Types of sleep

During each night a person goes through two stages of sleep that alternate with each other.They are

1)Slow wave sleep and

2)REM sleep

Slow wave sleep

In this type of sleep the brain waves are very slow.Though this sleep is frequently called “dreamless sleep”,dreams actually occur very often and even nightmares occur during this sleep.During this sleep the process of consolidation of the dreams in memory does not occur.This sleep is highly useful in decreasing blood pressure, respiratory rate and basal metabolic rate.

REM sleep or Rapid eye movement sleep

In a normal night sleep,REM sleep lasting 5-30 minutes usually appear on an average every 90 minutes.It is usually associated with active dreaming.The muscle tone throughout the body is exceedingly depressed during this sleep indicating strong inhibition of the spinal projections from the reticular formation of the brain stem.

The heart rate and respiration usually become irregular,which is characteristic of the dream state.During REM sleep,the brain is quite active.But,the brain activity is not channeled in the proper direction for persons to be aware of their sorroundings and therefore to be awake.

Physical effects of sleep

Sleep restores both normal sensitivities of nervous system and “balance” among the different parts of the central nervous system.Due to good sleep arterial blood pressure falls,pulse rate decreases,skin vessels dilate, muscles fall into relaxed state and overall metabolic rate of the body falls by 10-30 Percent.

UNDERSTANDING SOFTWARE DEVELOPMENT LIFE CYCLE

In todays cyber world we are driven with a technical life style which introduces software to be an integral part in our day to day life. It is hardly possible to imagine our every day life with out any computerized process. When we closely observe the applications that we use daily we all get a common doubt that, how were these applications are developed and what is the process behind them? Let me explain you about the process of developing a software keenly.

SOFTWARE DEVELOPMENT LIFE CYCLE:

Whenever there is a need for sophisticated system or an end user web or a mobile application we have to design a procedure which describes the whole process of development from starting stage to final stage. Similarly, Software development life cycle is also a methodology or a set of principles that should be followed in every software development team as preliminary steps to development a software.

This software development life cycle organizes the whole work process of the project into different stages which simplifies the work in order to complete it in the desired dead lines and it also focusses on the cost of project development. According to the project type we can apply different software development life cycles. The different SDLC processes applied by the companies are Agile model, RAD model, Waterfall model, Spiral model etc…. Though there are different models for the different kinds of projects, we use the following stages most frequently.

THE STAGES OF SOFTWARE DEVELOPMENT LIFE CYCLE:

1) BRAIN STORMING (OR) PLANNING: This is the first and fore most step in the software development life cycle process. This stage include brain storming session and then the development team finalizes an idea to proceed further into the project. After the completion of brain storming the team plans about the initial and core stages of the project and they also set the time frames and strategies to complete the project. When the prerequisite stage is perfectly completed then only the can move to the requirements stage.

2) DEFINING REQUIREMENTS: In this stage the team understands the project in deeper and classifies the requirements according to the stages of the project development and also in this stage only the team analyzes the future risks of the project and comes to a conclusion on the overall cost of the project.

3) DESIGN: Software design is the most complicated stage in the project development cycle. During this phase the team conceptualizes the created solution and verifies that whether the created solution meets the requirements or not. In this stage the team concentrates on the functionality of the solution and also analyze the structure capabilities, objectives of the proposed solution. After identifying a certain design for the development of software team forward in to development stage.

4) DEVELOPMENT: The development stage is all about converting the design into the actual software through coding. This stage of the development cycle is the longest path as it is the back bone of the whole project and the software development team should have to verify the code constantly to meet the requirements of the project. Once the development of complete architecture of the solution is completed. The team proceeds to the testing stage.

5) TESTING: In this stage the developed solution is tested under different methods in order to fix the bugs in the code and all the verified code at different stages are integrated in this stage. The testing stage is mainly useful for checking the quality of developed code prior to its release.

6) IMPLEMENTATION & MAINTENANCE: Once the software is certified with out having any errors or bugs then the team will release the developed software to production environment. This means the developed software product can be used by customers. Though the software is implemented also the development team must focus on the maintenance of the software in order to fix the bugs and update the new features.

These are the stages that are commonly used in every software development life cycle by a developer team. This SDLC process is use full to make perfect time frames for the completion of desired software product and also SDLC gives a perfect figure about total cost accomplished for the development of the project at every stage. Finally, SDLC is a process which sets the whole work in an organized and simplified manner.

Journalism and mass media

INTRODUCTION:-

Journalism and mass communication graduates work nationwide and worldwide at newspapers and magazines and in advertising, branding, broadcast news, social media, marketing, media research, photojournalism, publication design, public relations, radio, and other areas

Journalism:-

Journalism is the activity of gathering, assessing, creating, and presenting news and information. It is also the product of these activities.Journalism can be distinguished from other activities and products by certain identifiable characteristics and practices. These elements not only separate journalism from other forms of communication, they are what make it indispensable to democratic societies. History reveals that the more democratic a society, the more news and information it tends to have.

1.What is journalism?

Journalism is the activity of gathering, assessing, creating, and presenting news and information. … Journalism can be distinguished from other activities and products by certain identifiable characteristics and practices.

2. What makes journalism different than other forms of communication?

The vast majority of this communication, however, is not news and especially not journalism. Almost 70 percent of email traffic is spam, according to web security company Symantec. In 2012, there were an average of 175 million tweets each day. But almost all – 99% — consisted of “pointless babble,” according to researchers at Carnegie Mellon University.

3. What is the purpose of journalism?

“The purpose of journalism,” write Bill Kovach and Tom Rosenstiel in The Elements of Journalism, “is not defined by technology, nor by journalists or the techniques they employ.” Rather, “the principles and purpose of journalism are defined by something more basic: the function news plays in the lives of people.”

4. The elements of journalism?

In their book The Elements of Journalism, Bill Kovach and Tom Rosenstiel identify the essential principles and practices of journalism. Here are 10 elements common to good journalism, drawn from the book.

5. What does a journalist do?

Asking who is a journalist is the wrong question, because journalism can be produced by anyone.At the same time, merely engaging in journalistic-like activity – snapping a cell-phone picture at the scene of a fire or creating a blog site for news and comment – does not by itself produce a journalistic product. Though it can and sometimes does, there is a distinction between the act of journalism and the end result.

6. The journalist as a ‘committed observer’

Gil Thelen, the former publisher and president of The Tampa Tribune, believes the journalist has a very specific role in society. He calls it the “committed observer.” What he means by that, Thelen explains, is that the journalist is not removed from community, though at times may stand apart from others so as to view things from a different perspective.

7. The theory of the interlocking public

The splintering of mass media audiences and the migration of information consumers to tens of thousands of niche web sites is further evidence that everyone is interested, and expert, in something. The diversity and magnitude of the public, in fact, is its strength. A mix of publics is usually much wiser than a public comprised of just the elite or one segment of special interest.

8. Bias and objectivity

Journalism attempts to be fair and accurate. It does this through objective methods and managing bias. The guides in this section help you understand and navigate those processes.

9. The lost meaning of ‘objectivity’

One of the great confusions about journalism, write Bill Kovach and Tom Rosenstiel in The Elements of Journalism, is the concept of objectivity. When the concept originally evolved, it was not meant to imply that journalists were free of bias. Quite the contrary. The term began to appear as part of journalism after the turn of the 20th century, particularly in the 1920s, out of a growing recognition that journalists were full of bias, often unconsciously. Objectivity called for journalists to develop a consistent method of testing information – a transparent approach to evidence – precisely so that personal and cultural biases would not undermine the accuracy of their work.

10. Understanding bias

For a time, “bias” was the term of choice to describe anything people hated about journalism, whether the power and influence of corporate news organizations to the choices reporters made in writing individual stories. In 2001, in fact, a book about media unfairness entitled “Bias” was number one on the New York Times bestseller list. In recent years the public seems to have adopted a more nuanced view of bias.  Perhaps this is because many critics have found their voice online – where studies confirm that half the blogs contain just the author’s opinion – or that one-sidedness has become a successful business model, as Fox News Channel and MSNBC have demonstrated.

What Is Mass Media?

INTRODUCTION:-

Mass media is communication that is to a large group, or groups, of people in a short time (Mass Media, 2013, p. … This can be written, spoken or broadcast communication. Some of the most popular forms of mass media are newspapers, magazines, radio, advertisements, social media, television, Internet, and films/movies.

Mass Media:-

Think about this for a second: whenever you want to hear your favorite song, watch your favorite show, or see the latest current events, where do you go? You more than likely turn on your television, radio, or computer. The source that the majority of the general public uses to get their news and information from is considered mass media.Mass media means technology that is intended to reach a mass audience. It is the primary means of communication used to reach the vast majority of the general public. The most common platforms for mass media are newspapers, magazines, radio, television, and the Internet. The general public typically relies on the mass media to provide information regarding political issues, social issues, entertainment, and news in pop culture.

There are 6 main types of Mass Media:

  1. Traditional Media
  2. Print Media
  3. Electronic/Broadcasting Media
  4. Outdoor Media or Out of Home Media (OOH)
  5. Transit Media
  6. Digital Media/New Media/Internet

1. Traditional Media:-

People have developed different ways of communication depending upon their local language and culture. Traditional media is one of the oldest types of mass media to transfer traditions and culture over generations. The tools of communication have been developed from beliefs, customs, rituals, and practices of society. Traditional media imparts indigenous ways of communication for ages. Further, this type of mass media varied as per each culture and society as every culture has their own mediums to communicate to their mass audience. Thus, the traditional media can be folk songs, dances, folktales and folklore as well as paintings, sculptures, stupas, statues and fairs, festivals, rural or community radio and announcement mediums like nagada, etc.

Forms of Traditional Media

  • Folk Dances
  • Folk Songs and Music
  • Theatre, Drama, and Folktales
  • Painting, Sculptures, Inscriptions, Statues, and Stupas
  • Motifs and Symbols
  • Announcements made by beating drums or ‘nagada’
  • Shadow Puppetry and String Puppetry
  • Storytelling
  • Nautanki
  • Fairs and Festivals
  • Rural Radio

2. Print Media

In simple words, Print Media is all about the printed form of information and news. Before the invention of the printing press, printed materials had to be hand-written that made mass distribution almost impossible. Print media is one of the basic types of mass media tools making it very popular and convenient to reach a wider audience. Newspapers are considered as the oldest forms of mass media after the traditional mass media as for a long period of time, the general public relied on newspapers to know the latest happenings in their local areas as well as from around the world. Thus, print media originally refers to newspapers and then expanded towards magazines, tabloids, promotional brochures, journals, books, novels and comics.

Forms of Print Media

  • Newspapers (broadsheet and tabloid)
  • Periodicals, Newsletters, and Magazines (general or specific interest)
  • Brochures, Leaflets and Pamphlets
  • Journals
  • Books, Novels and Comics

3. Electronic/Broadcasting Media

Broadcasting is simply a distribution of audio and video content to a dispersed audience using the electronic broadcasting medium. Originally the term ‘broadcasting’ referred to the sowing of seeds on farms by scattering them over the large field. Broadcast media allows ease of news dissemination to even an illiterate person because it appeals to both the auditory and visual senses making it one of the most lucrative types of mass media. Centuries later after the newspapers were used as the original mass media, the advent of radio and television happened. Radio was the primary medium of news for the general public during wars as well as for sports and entertainment. When television was invented, it became the most effective type of mass media as it was primarily used for news dissemination and then for TV shows, live events and other entertainment purposes.

Forms of Broadcasting Media

  • Television
  • Radio (AM, FM, Pirate Radio, Terrestrial Radio, and Satellite)
  • Traditional Telephone
  • Film/Movie/Motion Picture
  • Video Games
  • Audio Recording and Reproduction

4. Outdoor Media or Out of Home Media (OOH)

This is also known as OOH or Out-of-Home Media and is focussed on transmitting information and news when the public is outside their home. Outdoor media gives importance to display advertising and attracting individuals towards new products, some social cause or any development or change in the society. These are prominent in brand promotion seen on buildings, streets, electric polls, roadside, vehicles, screens, kiosks, etc. This is one of the most prominent types of mass media used for commercial as well as public welfare advertising and mainly includes billboards, banners, posters, brochure distribution, ComPark Advertising, Wallscape, amongst others!

Forms of Outdoor Media

  • Billboards or Bulletins
  • Inflatable Billboards
  • Mobile Billboards
  • Banner
  • Lamppost Banners
  • Posters
  • Signs and Placards
  • Blimps, Skywriting
  • Brochure distribution
  • ComPark Advertising
  • Wallscape

5. Transit Media

Transit Media revolves around the concept of advertising and information dissemination when consumers are “on the go” in public places or in transit. These include display advertising on vehicles and transportation. With the aim “driving home a message” transit media is significantly used for massive brand promotion to millions of people who travel the country’s streets and highways every day.Some people might think that this type of mass media is outdated or ineffective, yet it is widely visible on the sides of buses, in subway cars, at transit stations where passengers enter or disembark from public transportation.

Forms of Transit Media

  • Bus Advertising
  • Railway Advertising
  • Taxi Advertising
  • Transit Shelter Advertising

6. Digital Media/New Media/Internet

Since the invention of the World Wide Web by English scientist Tim Berners-Lee in 1989, the Internet has drastically taken over all the types of mass media because of faster dissemination speed and higher digital technology. New Media is an interactive two-way communication with users being the active producers of content and information. The Internet is considered as a highly interactive mass medium and can be simply defined as the “network of networks”. It has quickly transformed as the centre of the mass media as it has marvellously integrated all the prominent types of mass media. Now, you can see news websites, broadcasted TV shows as well as listen to online radio using the internet and this is also called as the convergence of mass media!New Media is normally a re-conceptualization of the existing media. This is a rapidly growing mass media with the ease of accessibility with a computer and an Internet connection (broadband or WiFi). From Story Writing and Graphic Designing to Multimedia and Animation, pursuing a career in this field can be highly advantageous.

Forms of Digital Media

  • Websites
  • Emails
  • Social Media and Social Networking Sites (SNS)
  • Webcast and Podcast
  • Blogging and Vlogging
  • IPTV (Internet Protocol Television)
  • E-forums and E-books
  • E-commerce and M-commerce
  • Digital Videos
  • Computer Animation
  • Digital Video Games
  • Human-Computer Interface
  • Virtual World & Virtual Reality

  • Enhances mental well-being

Gratitude has a significant positive effect on psychological well-being. It boosts our self-esteem, stimulates positive thoughts, and elevates our optimism. In an older research from 2003 it has been found out that gratitude was connected to enhanced mood. Recently, According to a study published in 2020, expressing thankfulness on a regular basis might help alleviate anxiety and depressive symptoms.

  • Immune system booster

Gratitude has been demonstrated to aid in the development of a positive attitude. Over the years various researches have been conducted which shows improved immune system and lower stress levels as a result of practicing gratitude. According to a 2004 assessment of data, stress reduces the immune response to possible physiological threats, but mental well-being can assist your body fight sickness which can be done by being thankful.

Gratitude is essential in the formation of new connections as well as the strengthening of old ones. According to a 2010 study, spouses who expressed appreciation to one another reported higher relationship satisfaction and pleasure the next day. Thus, it can be said that Gratitude might make couples feel more happy with one other in love relationships and help them in building a strong relationship with each other.

  • Boosts optimism

It also makes a person optimistic who thinks that good things will happen. It can be concluded by seeing the result of 2018 study which states that gratitude practice might help you create an optimistic perspective if you’re not typically optimistic. A study was also conducted in 2003 on participants in which Participants felt more hopeful and positive about their current lives and the future after just 10 weeks of frequent gratitude practice.

So, I want to conclude that Gratitude is essential for bringing about change in one’s life. It relieves tension, makes you humble, and improves the quality of your relationships. It takes away your bad energy and replaces it with positivity. I believe that everyone should master the art of thankfulness in order to witness a positive shift in their lives.

Introduction about different Schools, Colleges, Universities

Introduction about different Schools:-

INTRODUCTION:-

ust as teachers may teach a broad spectrum of subject matter from math, science, English, to foreign languages, technology and the arts, they also teach across a wide age range and in many different classroom settings around the country.

The specific type of school in which a teacher teaches can have a huge impact on many aspects of their teaching career. From public schools — including magnet schools, charter schools, urban schools, rural schools and high needs schools — to private schools including military schools and boarding schools, every classroom setting is different and each has it’s own unique benefits and challenges. Deciding where you are best able to make a difference can be difficult.

Learn more about each type of schools to help you decide where you can fit in best:

  • Public Schools
  • Charter Schools
  • Magnet Schools
  • Private Schools
  • High Needs Schools
  • Urban Schools
  • Rural Schools

1. Public Schools:-

 A public school is government funded and all students attend free of cost.Because of funding from several sources, private schools may teach above and beyond the standard curriculum, may cater to a specific kind of students (gifted, special needs, specific religion/language) or have an alternative curriculum like art, drama, technology etc. Public schools have to adhere to the curriculum charted out by the district, and cannot deny admission to any child within the residential school zone.Public schools are often thought of as shoddy, less disciplined and low-grade curriculum.

2. Charter Schools:-

A charter school is a public school that operates as a school of choice. Charter schools commit to obtaining specific educational objectives in return for a charter to operate a school. Charter schools are exempt from significant state or local regulations related to operation and management but otherwise adhere to regulations of public schools — for example, charter schools cannot charge tuition or be affiliated with a religious institution.In other words, charter schools are publicly accountable — they rely on families choosing to enroll their children, and they must have a written performance contract with the authorized public chartering agency. Charter schools are also autonomous — they have more flexibility in the operations and management of the school than traditional public schools.

3. What Is A Magnet School:-

Unlike charter schools or private schools, a magnet school is part of the local public school system. At regular public schools, students are generally zoned into their schools based on the location of their home – students go to the school that is nearest where they live. However, this may not always be true since boundaries can seem arbitrary and in some smaller towns schools are not zoned at all. But, magnet schools exist outside of zoned school boundaries. Whereas private schools are completely separate from local public school districts, and charter schools are public schools with private oversight, magnet schools remain part of the public school system and operate under the same administration and school board.

4. Private Schools:-

Many of the private primary and secondary schools in the United States were founded by religious institutions in order to incorporate religious beliefs and teachings into their students’ education, integrating it with a traditional academic curriculum. Some of the first religious schools were founded by the Catholic Church, and these parochial schools are still prevalent amongst private schools. Since then, however, many other religious denominations have started schools to provide religious education, and families often choose to enroll their children in schools whose policies reflect their own values. Nowadays, Protestant, Jewish, Muslim, Orthodox Christian and other religiously based schools are quite common. In addition, some private schools, boarding schools and military academies, offer their own unique approaches to education.

5. High Needs Schools:-

The No Child Left Behind Act of 2001 External link  defines a high-needs school as “within the top quartile of elementary and secondary schools statewide, as ranked by the number of unfilled, available teacher positions; or is located in an area where at least 30 percent of students come from families with incomes below the poverty line; or an area with a high percentage of out-of-field-teachers, high teacher turnover rate, or a high percentage of teachers who are not certified or licensed.” Essentially, high needs schools require teachers because they cannot fill job vacancies or retain teachers, or they have teachers who are not qualified or who teach in subjects outside their field. High-needs schools also serve communities of higher poverty rates, where classrooms are influenced by the difficulties of their students’ lives. Most high-needs schools are located in rural or urban areas.

6. Urban Schools:-

When thinking of high need schools, the first thing that comes to mind for many people is the image of an inner city school, crowded and poorly funded. The truth is, while this is a stereotype and many urban schools perform exceptionally well, there are still urban schools across the country that are in high need of teachers and resources.At the most technical level, urban schools are classified as city schools by the National Center for Education Statistics External link  (NCES). The NCES categorizes all schools into four locales by their size, population density and location in relation to a city. This is an “urban-centric” classification system. The four locale categories used by the NCES’ urban centric classification system External link  are city, suburb, town and rural. Urban schools are then broken down into three subcategories based on the Census Bureau External link ’s definitions of urbanicity:

7. Rural Schools:-

Ultimately, the technical definition of a rural school corresponds to our general understanding of rural areas; they are characterized by geographic isolation and small population size. All schools are categorized into four locales by their size, population density and location. The National Center for Education Statistics External link  (NCES) defines these locales by the school’s proximity to a city an “urban-centric” classification system. The four locale categories used by the NCES’ urban centric classification system External link  are city, suburb, town and rural. Rural schools are then broken down into three subcategories based on the Census Bureau External link ’s definitions of urbanicity. Rural schools are also all classified as high need schools.

Introduction about different Colleges:-

INTRODUCTION:-

college (Latin: collegium) is an educational institution or a constituent part of one. A college may be a degree-awarding tertiary educational institution, a part of a collegiate or federal university, an institution offering vocational education, or a secondary school.

In most of the world, a college may be a high school or secondary school, a college of further education, a training institution that awards trade qualifications, a higher-education provider that does not have university status (often without its own degree-awarding powers), or a constituent part of a university. In the United States, a college offers undergraduate programs; it may be independent or the undergraduate program of a university, it is generally also used as a synonym for a universitywhile in some instances a college may also be a residential college. A college in francophone countries [fr]—France (see secondary education in France), Belgium, and Switzerland—provides secondary education. However, the Collège de France is a prestigious advanced research institute in Paris.

Learn more about each type of colleges to help you decide where you can fit in best:

  • Community and Junior Colleges
  • Historically Black Colleges and Universities 
  • Liberal Arts Colleges
  • Women’s Colleges
  • Tribal Colleges
  • Technical Institutes and Professional Schools

1. Community and Junior Colleges:-

These colleges offer the first two years of a liberal arts education, as well as career or vocational training. Successful completion of a community or junior college curriculum earns graduates an associates degree. Many students continue on to a four-year institution after completing a community or junior college program.

2. Historically Black Colleges and Universities:-

These colleges originated when African-American students were legally denied access to most other institutions of higher education. Now, these colleges celebrate African-American culture and empowerment, and give black students the chance to experience an educational community in which they are finally part of the majority. A common abbreviation for this type of college is HBCU.

3. Liberal Arts Colleges:-

These colleges focus on the education of undergraduate students (students who are earning a bachelors degree). Classes are generally taught by professors who see teaching as their primary responsibility. Because most liberal arts colleges are smaller than universities, classes tend to be smaller and more personal attention  is available. Instead of preparing for a specific career path, students who attend liberal arts colleges are exposed to a broad sampling of classes. In addition, they select at least one area of in-depth study that is their college “major.” Many employers look for graduates of liberal arts programs.

4. Women’s Colleges:-

These colleges offer women the opportunity to enjoy a learning community where they are in the majority. Additionally, these colleges have a much larger population of female faculty and administrators. Women’s colleges graduate a high number of science majors, as well as students who continue on to graduate school or professional studies.

5. Tribal Colleges:-

Like HBCUs or Women’s colleges, these colleges focus on the needs and education of a group that has been traditionally underrepresented in higher education. In this case, these colleges focus on the education and empowerment of Native American students while celebrating a specific tribe’s unique culture and accomplishments.

6. Technical Institutes and Professional Schools:-

These colleges or institutes enroll students who have made a choice as to what career path they are taking. The curriculum at these colleges focuses solely on preparing students for these specific careers. Most of the career options offered at these colleges are in music, fine arts, engineering, or technical sciences.

Introduction about different Universities:-

INTRODUCTION:-

The original Latin word universitas refers in general to “a number of persons associated into one body, a society, company, community, guild, corporation, etc”. At the time of the emergence of urban town life and medieval guilds, specialized “associations of students and teachers with collective legal rights usually guaranteed by charters issued by princes, prelates, or the towns in which they were located” came to be denominated by this general term. Like other guilds, they were self-regulating and determined the qualifications of their members.

In modern usage the word has come to mean “An institution of higher education offering tuition in mainly non-vocational subjects and typically having the power to confer degrees,” with the earlier emphasis on its corporate organization considered as applying historically to Medieval universities.The original Latin word referred to degree-awarding institutions of learning in Western and Central Europe, where this form of legal organisation was prevalent and from where the institution spread around the world.

Learn more about each type of Universities to help you decide where you can fit in best:

  • Central universities, or Union universities
  • State Universities
  • Private Universities
  • Deemed university

1. Central universities, or Union universities:-

in India are established by an Act of Parliament and are under the purview of the Department of Higher Education in the Ministry of Education.In general, universities in India are recognised by the University Grants Commission (UGC), which draws its power from the University Grants Commission Act, 1956.In addition, 15 Professional Councils are established, controlling different aspects of accreditation and coordination.Central universities, in addition, are covered by the Central Universities Act, 2009, which regulates their purpose, powers, governance etc., and established 12 new universities.As of 1 June 2020, The list of central universities published by the UGC includes 54 central universities.

Other types of universities controlled by the UGC include:

  • State universities are run by the state government of each of the states and territories of India, and are usually established by a local legislative assembly act.
  • Deemed university, or “Deemed-to-be-University”, is a status of autonomy granted by the Department of Higher Education on the advice of the UGC, under Section 3 of UGC Act, 1956.
  • Private universities are approved by the UGC. They can grant degrees but they are not allowed to have off-campus affiliated colleges.

Apart from the above universities, other institutions are granted the permission to autonomously award degrees. These institutes do not affiliate colleges and are not officially called “universities” but “autonomous organisations” or “autonomous institutes”. They fall under the administrative control of the Department of Higher Education.These organisations include the Indian Institutes of Technology, the National Institutes of Technology, the Indian Institutes of Science Education and Research, the Indian Institutes of Engineering Science and Technology, the Indian Institutes of Management, the National Law Schools, the All India Institute of Medical Sciences, and other autonomous institutes.

2. State Universities:-

State universities are run by the state government of each of the states and territories of India, and are usually established by a local parliament act. As of 26 August 2011, the UGC lists 281 state universities, around 170 of which are receiving Central/UGC assistance. The oldest establishment date listed by the UGC is 1857, shared by the University of Mumbai, the University of Madras and the University of Calcutta.

In India, state universities are run and funded by the state government of each of the states of India.Following the adoption of the Constitution of India in 1950, education became a state responsibility. Following a constitutional change in 1976, it became a joint responsibility of the states and the central government.As of 17 March 2021, the UGC lists 426 state universities.

3. Private Universities:-

Private universities are approved by the UGC. They can grant degrees but they are not allowed to have off-campus affiliated colleges. The UGC list from 1 September 2011 lists 94 private universities.

Private universities and private colleges are usually not operated by governments, although many receive tax breaks, public student loans, and grants. Depending on their location, private universities may be subject to government regulation. This is in contrast to public universities and national universities. Many private universities are nonprofit organizations.

4. Deemed university:-

Deemed university, or deemed-to-be-university, is an accreditation granted to higher educational institutions in India, conferring the status of a university. It is granted by the Department of Higher Education.To quote the Ministry of Human Resource Development (MHRD), “An Institution of Higher Education, other than universities, working at a very high standard in specific area of study, can be declared by the Central Government on the advice of the University Grants Commission (UGC), as an Institution ‘Deemed-to-be-university’. Institutions that are ‘deemed-to-be-university’ enjoy the academic status and privileges of a university.”

Deemed university, or “Deemed-to-be-University”, is a status of autonomy granted by the Department of Higher Education on the advice of the UGC, under Section 3 of UGC Act, 1956. The UGC list from 23 June 2008 lists 130 deemed universities. According to this list, the first institute to be granted deemed university status was Indian Institute of Science which was granted this status on 12 May 1958. Note that in many cases, the same listing by the UGC covers several institutes. For example, the listing for Homi Bhabha National Institute covers the Institute of Mathematical Sciences, the Indira Gandhi Centre for Atomic Research and other institutes. The list below includes only the major institute granted the status, and such additional institutes are not listed separately.

Broken heart 💔

The day you made me realize that you’re not mine, you broke my heart into pieces but I wonder how, each and every single peace of it loves you still !!! They say crying all alone makes you forget even someone special, but even then my every little water drops brings back your memory and makes me cry even more. I literally can’t sleep or even relax for a minute if I come to know that someone is crying because of me, but I don’t know how , you make me cry each and every second and you still remain silent even after knowing that, you’re the reason of it.

” YOUR SILENCE KILL ME MORE, THAN YOU SPEECH”

” Sometimes we put up walls, not to stay away from people but to see who cares enough” but you never turned up….

Every time I come to online to check whether you’re in ,the moment I see you online I feel happy but the next minute I fall into depression by realising that, it was not for me…I know very well my tears can’t bring you back to me but, I’m in a state where I can’t control myself.

I wanted to spend time with people to come out of your memories but I could see only one face in each and every one of them and that’s you…

I’m sure I can’t live without you….

“I WILL WAIT FOR YOU IN THE SAME PLACE WHERE YOU LEFT ME ,TILL THE DAY I CAN FORGET YOU OR TILL THE DAY YOU REALIZE YOU CAN’T FORGOT ME”….

PROBLEM OF GARBAGE IN INDIA

Urban India generates 62 million tonnes of waste (MSW) annually, and it has been predicted that this will reach 165 million tonnes in 2030. 43 million tonnes of municipal solid waste is collected annually, out of which 31 million is dumped in landfill sites and just 11.9 million is treated.

Burying garbage also causes both air and water pollution, and simply transporting it to the sites consumes an increasing amount of valuable fossil fuels, which produces more pollution and other problems. Buried in a landfill, the typical plastic trash bag takes 1,000 years to degrade, giving off toxins as it does.

The reason why most landfill sites are over-flowing is because the current waste disposal system is flawed. Nearly 20% of methane gas emissions in India is caused by landfills. The trash dumped in the landfills are prone to catching fire due to the heat generated by the decomposition of waste.

The amount of rubbish produced by an average household has increased dramatically over the last few decades. This trend is mainly due to consumption and abundance of plastic. … Now they buy packed food from supermarkets which creates a myriad of plastics waste through its packaging.

India faces major environmental challenges associated with waste generation and inadequate waste collection, transport, treatment and disposal. Current systems in India cannot cope with the volumes of waste generated by an increasing urban population, and this impacts on the environment and public health.

Steps we can take to ensure the environment clean —

• Donate Clothes.

• Reduce Food Waste.

• Meal Plan.

• Eat Healthy.

• Save Leftovers for Next Day.

• Buy Things in Bulk with Less Packaging.

• Avoid Food Wrapped In Plastic.

• Bring Your Own Bag.

• Avoid plastic and one time usable plastic

Energy from waste can be used to produce heat or electricity, which might then replace the energy produced using coal or other fuels. Energy recovery of waste can thus help reduce greenhouse gas emissions. Recycling can help even more to lower greenhouse gas emissions and other emissions

Proper waste management helps improve the quality of water and air, as well as reduce the emission of greenhouse gases. … So, when they collect the waste, they are usually salvaged for redistribution, recycling and reuse. By booking a skip bin, you can reduce pollution and lower the demand for producing new materials.

Elon Musk

Elon musk is South African-born American entrepreneur and a business magnate. He is one Billionaire in the world. He is the founder and CEO of SpaceX, CEO of Tesla, founder of Boring company and Co-founder of OpenAI and Neuralink. In this blog, we are going the discuss the success story of Elon Musk.

PERSONAL LIFE

Elon Revee Musk was born on 28 June 1971 in Pretoria, South Africa. His father is Errol Musk, a electromechanical engineer, pilot and a sailor. His mother is Maye Musk, who is a model. From a very young age Elon musk was very interested in computers and programming. At the age of 12, he created a video game and sold it to computer magazines for $500. His friends used to tease him calling introverted child. After his parents divorced in 1980, he used to live with his father. After two years, he estranged from his father.

EDUCATION

Musk studied in Waterkloof House Preparatory school and Bryanston High School before graduating from Pretoria Boys High School.After that his high school, he want to study in America and by knowing that it would be easily to enter in America through Canada. In 1988, Musk applied to Canadian passport through his Canadian born mother after obtaining the passport he left South Africa because of the apartheid system, that force to work in South Africa Military. After arriving in Canada, he was failed to stay with his great-uncle instead of that he stayed at a youth hostel. In 1990, he enrolled in Queen’s University in Kingston, in Ontario. After two years, he transferred to University of Pennsylvania. In 1995, he enrolled in Stanford University to study P.H.D in Material Science. Just after two days, he decide to left Stanford University to start an Internet Startup. In 1997, he graduated from University of Pennsylvania with a bachelor degree in Economics and bachelor of Arts degree in Physics.

BUSINESS CAREER

ZIP2

In 1995, Musk with his brother Kambal and Gred Kouri founded ZIP2 company, which provides map, directions to news paper publishing industries. Musk used to write code all days in a week for zip2. In 1999, Compaq(a computer manufacturing company) bought zip2 for $307 million, in which musk got $22 million for his 7 percent share in ZIP2 company.

X.com and PayPal

In 1999, Musk Co-Founded X.com, which was an online e-mail payment company. Within its initial months, the company eventually reached 200000 customers joined the company. In the same year, X.com merged with Confinity, which had its own money-transfer service PayPal. In 2001, the company renamed as PayPal. In 2002, eBay bought PayPal for $1.5 Billion in stock in which Musk was the largest stakeholder with 11.7 percent and received 100 million.

SpaceX

In February 2002, Musk founded Space Exploration Technologies Corporation traded as SpaceX with his $100 million. In 2006, SpaceX launched there first rocket, Falcon 1 but it failed in just 33 seconds. In 2007, SpaceX launched there second rocket, this due to engine failure the engines shutdown completely and the fail to reach the orbit. Another failure for SpaceX. Then SpaceX launched there third rocket, this time also it failed. The failure almost killed the company. After three failed launches, SpaceX successfully launched there 4 rocket. It was the first privately fueled rocket to reach the earth orbit. After the successful launch, SpaceX received $1.6 Billion for Commercial Resupply Service contract.

Why we should exercise?

Exercise is physical activity that is planned, structured and repetitive for the purpose of conditioning any part of the body used to improve health and maintain fitness. Generally you work up a sweat, breath heavy and increase your heart rate during exercise.

The muscle inactivity always leads to weakness and wasting of muscles.Muscles are no exception to the saying “use it or lose it”.Regular exercise increases muscle size, strength and endurance.There are several exercises according to the needs and benefits.For example jogging or biking results in stronger,more flexible muscles with greater resistance to fatigue.Stamina formation is mainly carried out through aerobic activities,such as running and swimming.

Benefits of aerobic exercise:

⭐Physical exercise is a major contributor to health and can improve the body in three ways:more efficient heart,and lungs, improved muscle tone,and more supply joints.

⭐It is also essential to prevent obesity.Due to regular exercise,blood supply to muscle increases,it results in supply of more oxygen.

⭐Further exercises make body metabolism more efficient, improve digestion and enhance neuromuscular coordination.

⭐Heart beat enlarges,so that more blood is pumped out with each beat,fat deposits are cleared from the blood vessels and the lungs become more efficient in gaseous exchange.

⭐These benefits may be temporary or permanent on the basis of regular and vigorous exercises.Aerobic exercises do not cause the muscle to increase in size,even though the exercise may go on for hours.

⭐Aerobic exercises increase the adaptability of muscles and give greater endurance to muscles.

⭐To gain good health,it is suggested that a total of atleast 20 minutes per day,of moderate exercise,to burn around 200 calories (837)a day,is required.Regular exercise is preferrable to occasional intense sessions.

The bulging of muscles of a body builder or proffesional weight lifter results mainly from resistance or isometric exercise in which muscles are pitted against some immovable,or nearly so, object.

Endurance and resistance exercises produce different patterns of muscle response,it is important to know what your exercise goals are.

Weight lift will not improve your endurance for a marathon race.At the same time, jogging will do little to improve your muscle definition nor will it make you stronger.Proper exercise for proper goal is necessary.

IMPACT OF COVID-19 ON EDUCATION IN INDIA

India is the one of best and largest place for education systems in the world.

India is the country with over 1,000 universities and 50,000 colleges and institutions. The impact of covid 19 is observed in every sector around the world. The education sectors of India as well as world are badly affected by this.

Due to this pandemic, around 32 crore learners stopped to move schools/ colleges, all educational institutions are halted in India. COVID-19 made all the institutions to grow and opt for platforms , techniques, that are not used before. All the classes suspended and all the examinations, entrance tests are postponed.

This pandemic completely destroyed all the schedules of every student. COVID-19 Impact on education is also leads a great damage on country economy at present and in future.

COVID-19 has created many opportunities and challenges for educational institutions to strengthen their technological knowledge and infrastructure.

The lockdown made the entire education online, the teachers are teaching and assigning works through online by using some apps like zoom, Google meet, teams, YouTube, Facebook, skype .,etc.

India is not fully equipped to make education reach every corner of the country through online process. The students those who are not having access to internet will suffer a lot due to the present choice of digital platforms.

Universities and the government of India are relentlessly trying to come up with a solution to this problem.

An Overview of the Stock Market

The stock market or the share market comprises of buyers and sellers of shares. The shares can be traded over private or public platforms. Investors who buy shares of any institution, are conferred ownership to a certain part of the institution. A company can build its market capitalization through its outstanding shares. There are various financial intermediaries that act as middlemen by overseeing the financial transactions made between two parties, such as banks, insurance, stock exchanges.

India has two stock exchanges -the NSE and the BSE. The stock market provides the pricing information resulting from the financial transactions, between the buyers and the sellers, of the market. The stock market is regulated by SEBI which is a regulatory body that issues guidelines to intermediaries and companies regarding the securities and capital, with the motive of ensuring the interests of the investors are protected. The BSE is one of the oldest stock exchanges in Asia and has a market capitalization of $3 trillion dollars. The BSE constitutes the indices of BSE SENSEX, S&P BSE Smallcap, Midcap and Largecap, BSE 500. The NSE is a government owned stock exchange also having a market capitalization rate of $3 trillion. The NSE considers the indices of NIFTY 50, NIFTY Next 50, NIFTY 500.

The stock market ensures liquidity by providing a mechanism for an investor to sell their financial assets. The comprisal of the stock market ranges from small companies to large companies. Small individual investors or large investing firms can invest in any stocks from any of the stock exchanges in the world. Today, stocks are traded over electronic platforms, making it convenient for investors to look up at stock prices, analyze their perceptions according to the price indices and invest. Back in the days, stocks were traded through brokers using physical mediums, like certificates or paper receipts, which involved more complexity in contrast to the advancing technology of today’s world.

The stock market exhibits both the primary market and the secondary market. The primary market offers new shares to the investors, the sale of securities to the public can be facilitated by underwriting institutions such as bank. In the secondary market the shares that are already in the public domain or with the investors, are traded with buyers and sellers. The investors in the secondary market trade stock with each other rather than with any issuing firm.

There are two types of offerings of shares to the public -IPO and FPO. IPO are initial offerings of shares to the public done via primary market. FPO are follow on public offerings wherein an issuance of additional shares is done by a company after IPO. The prices of the shares offered in IPO are fixed, while the price of shares in FPO is deemed based on their market value.

Some companies have dividend payments which is a sort of reward to the investors for investing in their business. Dividends are the distributions of a company’s earnings to its shareholders.

Today, investors have an option for a better portfolio management, as investors can manage their risk by diversifying their investments among various financial instruments. Building a proper portfolio requires proper analysis of stock, bond or any other commodity and can bring in profits to the investor. 

Database Concepts

Database :- It is collection of information in such a way that computer program can quickly retrieve desired pieces of data and do operations.

DBMS ( Database management system) :- It is collection of programs that allows us to store, modify and extract information from database.

Data Independence :- Data independence implies that data stored at different levels should not affect each other when get changed.

Table :- A predefined row/column format for storing information in relational databasse.

Attributes :- Columns of table are called attributes.

Tuples :- Rows of table are called tuples.

Degree :- Number of attributes (columns) in a relation is called its degree.

Cardinality :- The number of tuples (rows) in relation is called cardinality.

Key :- Keys help in identifying, retrieving and establishing relationship among tables. There are various keys some of them are primary key, foreign key, alternate key, etc.

Data Integrity :- It means that one person can correctly and consistently navigate and manipulate the tables in database.

Entity Integrity :- It state that value of primary key can never be null and for each roe, it should be unique.

Referential Integrity :- It state that if a relational table has foreign key, then every value of foreign key must be either null or match the value in the relational table in which foreign key is a primary key.

Join :- It is used to combine related tuples from two relation. The join operator is cross product of two relations.

SQL (structured Query Language ) :- It is standard language used for communicating with RDBMS. It looks like English language.

DML ( Data Manipulation Language ) :- It is a part of SQL that provides statements for manipulating database. DML statements can modify the data stored in a database, but they can’t change its structured. Some of DML statements are : Insert Into, Delete , Select, Update, etc.

DDl ( Data Definition language ) :- It is a part of SQL that provides statements for creation and deletion of database. DDL statements are : Create Table, Alter Table, Drop Table, Create Index, etc.

Manali flooded with tourist amid third wave warning; covid protocols getting ignored.

Inspite of third wave warning lakhs of tourists have thronged Himachal Pradesh in less than a month.Videos emerging from Manali and Shimla show that social distancing norms put in place to contain the coronavirus pandemic have gone for a toss.Highways choked, hotels fully booked after the Himachal Pradesh government relaxed Covid-19 related restrictions.Hotel occupancy in major tourist spots, including Shimla, Manali and Dharamshala, is almost full and tourists have been heading to less popular tourist spots in a bid to find accommodation and in guest houses.

Even though the governments, health experts have been warning against large crowds, a sea of tourists was seen in Manali town in Kullu district as the Himachal Pradesh government eased COVID restrictions.the increase in the number of tourists has posed a challenge for the authorities who are struggling to ensure implementation of Covid protocols amid fears of an impending third wave of coronavirus infections.

Reason behind this huge influx of tourist

  1. The prime reason is that the Himachal administration has withdrawn the mandatory need of a negative RTPCR report and e-Covid pass to enter the hill state.
  2. Another reason, behind the rush of tourists, is the ongoing heatwave in North India.
  3. while the third reason is that some people fear that lockdown-like restrictions may be imposed if the third wave of coronavirus strikes the nation. So many have decided to use this opportunity to visit some places

Twitterati reaction

Social media was abuzz with pictures of crowded Manali markets and tourist spots. While some were concerned over the violation of Covid protocols by the tourists, others shared memes and took taunt at the carelessness of the public.

Description of Metals, non-metals and metalloids


The process of man towards civilization is linked with the discovery of several metals and non-metals. Even today, the index of prosperity of a country depends upon the amount of metals and non-metals it produces. The wealth of a country is measured by the amount of gold in its reserve.

 An element can be identified as metal or non-metal by comparing its properties with the general properties of metals and non-metals. In doing so, we find that some elements neither fit with the metals nor with non-metals.

Such elements are called semi-metals or metalloids. Elements are classified into metals, non-metals and metalloids based on their properties.

METALS


Iron, copper, gold, silver, etc. That we use in our daily life are metals. The properties and uses of metals are given below.

PHYSICAL PROPERTIES OF METALS
Metals are solid under normal conditions of temperature and pressure.
Most metals are hard.
All metals are shiny. The typical shine of metals is called metallic lustre.
Metals generally have high density.


Metals in general have high melting point and boiling point.
Metals can be hammered into very thin sheets. This tendency of metals is called malleability. Using this property aluminium is transformed into silvery foils.
Metals can be drawn into thin wires. This property of metals is called ductility. Example : copper wires.
Generally metals are good conductors of heat and electricity.
On being hit, metals produce a typical sound. Hence, they are said to be sonorous. This property is being made used in making temple bells.

USES OF METALS
Iron is used for making bridges, engine parts, iron-sheets and bars.
Copper is used for making electrical wires, coins and statue.
Silver and gold are used for making jewels and for decorative purposes and photography.


Mercury is used in thermometers and barometers because of its high density and uniform expansion at different temperature.
Aluminium is used in electrical wires, cables and in aerospace industries.
Lead is used in automobile batteries, X-ray machines


NON-METALS


Elements like sulphur, carbon, oxygen etc. are non-metals. Some of the properties and uses of non-metals are given below.

PROPERTIES OF NON-METALS
Non-metals occur as solids, liquids or gases at normal temperature. For example, sulphur and phosphorus occur in solid state while bromine occurs in liquid state. Elements like oxygen, nitrogen etc., occur in gaseous state.
Non-metals are generally not hard except diamond (a form of carbon).
Non-metals have a dull appearance.


Non-metals are generally soft and have low densities. The exception here is a diamond (a form of carbon) which is the hardest naturally occurring substance.
Non-metals have low melting point and boiling point.
Non-metals are non-malleable.
Non-metals are not ductile. Carbon fibre is highly ductile.
Non-metals are generally bad conductors of electricity. Graphite (a form of carbon) is an exception.
Non-metals do not produce sound (non-sonorous) when hit.


USES OF NON-METALS
Diamond (a form of carbon) is used for making jewels, cutting and grinding equipments. Graphite is used in making pencil lead.
Sulphur is used in manufacturing of gun powder and vulcanization of rubber.


Phosphorus is used to make match boxes, rat poison etc.,
Nitrogen is used for manufacturing ammonia.
Chlorine is used as a bleaching agent and in sterilizing water.
Hydrogen is used as a rocket fuel and hydrogen flame is used for cutting and welding purposes. Hydrogen is also used as a reducing agent.

METALLOIDS
The elements which exhibit properties of metals as well as non-metals are called metalloids.

Examples: Boron, Silicon, Arsenic, Germanium, Antimony, Tellurium and Polonium.

PHYSICAL PROPERTIES OF METALLOIDS
Metalloids are solids at room temperature.
They can form alloys with other metals.
Some metalloids, such as silicon and germanium, can act as electrical conductors under specific conditions. Thus, they are called semiconductors.

Elements classified as Metalloids have physical properties of both metals and non-metals. SHINY. Some are DULL. somewhat MALLEABLE and DUCTILE. SEMI CONDUCTOR of heat and electricity – conducts at a lesser level than metals. SILICON. ARSENIC. BORON.


Silicon which is a metalloid appears lustrous, but it is neither malleable nor ductile. It is brittle – a characteristic of some non metals. It is a much poorer conductor of heat and electricity than the metals.
The physical properties of metalloids tend to be metallic, but their chemical properties tend to be non-metallic.

USES OF METALLOIDS


Silicon is used in electronic devices.
Boron is used in fireworks and as a fuel for ignition in rocket.
