Solar air conditioning and efficient, low-consumption cooling systems work together.

Researchers from the Universitat Politècnica de València (UPVCMT-Motores )’s Térmicos (Thermal Engines) group are developing new, more efficient cooling systems that use solar air conditioning, which will assist in addressing the summer increase in electricity bills Their study results made an appearance in the International Journal of Refrigeration.

“In the last month, the ‘perfect storm’ has occurred in all aspects of the electricity bill. On the one hand, there is the so-called rate change, which is divided into three segments, and on the other, there are consumption peaks in the summer during the hottest days of the year. In these days of high temperatures, air conditioning units and cooling systems consume more electricity, raising the cost of electricity significantly—without going any further, the price of electricity surpassed its annual record last Saturday. Solar air conditioning, while an oxymoron, has the potential to be a solution to this perfect storm, says “José Ramón Serrano”, a CMT researcher.

Solar air conditioning equipment

Solar air conditioning is the equipment used to cool a space with solar energy. Two main groups are involved, as explained by Serrano: on the one hand, photovoltaic panels are used to produce traditional air conditioners. The problem with these solutions is their low efficiency: barely 10 percent, which means the nearly 1,000W per sqm that we get with the most solar radiation during the summertime, generates only 100W of electricity. “This represents about 300 W of cooling power in a traditional cold unit,” Serrano describes.

Solar thermal cooling systems, on the other hand, are more efficient and versatile. In this case, thermo-solar panels are used in place of photovoltaic panels that warm up a liquid by using surfaces that absorb or concentrate solar rays. These systems are used in the cold winter months in households to heat sanitary water and solar heating systems. The CMT-Motores Térmicos researchers concentrate their efforts on the latter to use them during the summer.

They propose coupling these panels to absorption or ejection cycles, which would allow them to cool the room using the sun’s heat as the source of energy. The 1,000 W per square meter received in these cases can be converted into 500 W of heating power using the thermal oil that flows through the thermo-solar panels. The 500 W can then be converted into 600 W of cooling power via high-efficiency absorption cycles.

“One advantage of using this equipment is that the cooling capability increases in tandem with the solar radiation, which coincides with periods of higher cooling demand,” says Vicente Dolz, UPV professor and CMT-Motores Térmicos researcher.

And how would this allow you to save money on electricity?

A typical household air conditioning unit in the living room has a cooling capacity of around 3,500 W. According to the UPV researchers, these values can be achieved with around 6 m2 of thermo-solar panels coupled to an absorption cycle during the hours of highest irradiation (midday in the summer) to completely replace the traditional air conditioning unit with the absorption cycle.

“A traditional air conditioning unit consumes approximately 1,170 W of electricity to achieve the 3,500 W of cooling power.” The technology that we propose would allow us to eliminate said consumption from our bills while enjoying the greatest level of comfort possible thanks to the combination of solar panels and absorption cycles.

CMT-Motores Térmicos proposed that solution can also be implemented as a hybrid system that provides part of the traditional system’s cooling capabilities or improves its efficiency while also reducing global electricity consumption by providing the solar air conditioning system.

STARTUP: A NEED OF HOUR

A startup is a young company founded by one or more entrepreneurs to develop a unique product or service, bring it to market and make it irresistible and irreplaceable for customers.

Startups are rooted in innovation, addressing the deficiencies of existing products or creating entirely new categories of goods and services, thereby disrupting entrenched ways of thinking and doing business for entire industries.

FACTORS THAT BOOST THE SUCCESS OF A STARTUP

•Expertise of Founder in Domain– An organisation is an artificial person and the founder is the one who determines whether it will survive or not. The founder needs to ensure that he/she has acquired adequate skills and knowledge about the domain and should not just step into it without any prior experience in the specific field. The more experience is held by its founder, more are the chances of its success.

•Passionate and Supporting Team– An organisation needs support of its members. A leader or a manager is nothing without his/her followers or sub-ordinates respectively. They need the support to create wonders. If an organisation is able to find such passionate and supporting employees, then the startup will definitely be able to crate a goodwill in no time.

•Committed and Hard Working Employees– Employee is that asset of an organisation that converts other assets into money. Capital is of use without Human Capital. Committed and Hard working employees don’t work for money but work for the belonging towards organisation. They give their best for success of organisation.

•Innovation– A market where the demand and requirements of consumers changes drastically, a new business needs to bring something new and out of the box that leaves a favorable impact on mind of customers to create a customer base.

•Not letting go even a small opportunity of Growth– A new organisation should grab each opportunity to show its uniqueness. Every opportunity have only two results either success or a learning that can act as a base for future success.

Sustainability In India

Pollution is not just an undesirable outcome that causes environmental deterioration in India; it is also a major roadblock to growth and development in the country. It would have a negative effect on economic growth if it is not addressed properly and managed.

This resulted in a major shift in people’s attitudes and political will. Significant advances in clean energy technologies have opened the path for commercial possibilities arising from the ‘green economy transformation.’ Clean technology will be in high demand. Countries that adequately upskill and establish industry sectors to manufacture it stand to benefit greatly. They may earn profit from clean technology exports and earn access to global markets.

While India already is trying to make tremendous progress in the field of sustainability, there seems to be an imperative need to involve our country’s youth in order to fulfil our sustainable development goals.

Sustainability became one of the most defining terms of the twenty-first century, and for valid reason: the contemporary world is now struggling with the consequences of unrestricted consumption and production tendencies. Simply stated, even as our population grows and technology advances at a breakneck pace, our quality of life is progressively deteriorating. India, which is on the verge of a new age of growth, is at an important crossroads in terms of its approach to sustainability. While our nation has some of the lowest per-capita emissions in the world, we are the third-largest emitter globally. The two most significant hurdles to our approach to sustainability are our population and the swift pace of our economic progress.

India, though, has made significant progress as an aspiring change-maker in addressing climate change and developing development plans which are in line with the Sustainable Development Goals, that were implemented in September 2015 and encapsulate the social, environmental, and social dimensions of sustainability, as well as the abolition of all forms of poverty.

To that aim, attempts have been made to include all stakeholders – public and private – in the development of successful guidelines, implementation methods, and best practises. For example, in February 2018, a nationwide seminar on capacity building was organised with the objective of localising the SDGs. In December 2018, the NITI Aayog released the SDG India Index — Baseline Report 2018 to monitor the progress the  states and union territories have made on the strategies and initiatives launched by the central government.

The country was also a significant participant in formulating the Paris Agreement and has implemented a variety of energy-efficiency initiatives. Sustainability is also an important aspect of Indian culture, thought, and beliefs. Rural areas, which accounted for about 70% of the nation’s population in 2011, maintain a modest and inexpensive way of living. According to Greendex, an international study on sustainable living which analyses how individuals respond to environmental issues in their housing, transportation, food, and products choices, India ranks first among 18 countries, including China and the United States.

India has also  had one of the most effective programmes in terms of eliminating single-use plastic and promoting the Swachh Bharat campaign, an initiative launched by the central government. This has aided in increasing awareness beginning in primary school, with children asking their parents about their right to cleanliness.

That being said, as the economy develops and grows, there is a noticeable change in socio-economic patterns. The nation still has to confront several  significant environmental challenges, particularly in terms of building sustainable communities.

Being one of the world’s youngest countries — 42% of India’s population is between the ages of 15 and 35, and this estimate is expected to rise to 55% in the coming 30 years — the youth in our country should be encouraged to develop environmentally friendly economic solutions.

Universal destruction

How could it be possible that when the time gets worse we often ignore the vulnerable?

Nikhil Meshram

We are living in the world , where no one can intrude . A life , where you can’t touch the one you want . A life, where one has to stay away from his own . A life , where no one can go in one’s home . Yes , it’s a life we are living ‘ A life of a LOG’ .

Coronavirus , I believe it’s not a new word in your dictionary . This eleven letter word creating a massive destruction all over the world . I know you are well aware but the real question is , are you following the protocols properly?

Firstly let’s get some knowledge about coronavirus.

The origin .

The recent outbreak began in Wuhan, a city in the Hubei province of China. Reports of the first COVID-19 cases started in December 2019.

Coronaviruses are common in certain species of animals, such as cattle and camels. Although the transmission of coronaviruses from animals to humans is rareTrusted Source, this new strain likely came from bats, though one study suggests pangolins may be the origin.

However, it remains unclear exactly how the virus first spread to humans.

Some reports trace the earliest cases back to a seafood and animal market in Wuhan. It may have been from here that SARS-CoV-2 started to spread to humans.

Coronaviruses are a group of viruses that can cause disease in both animals and humans. The severe acute respiratory syndrome (SARS) virus strain known as SARS-CoV is an example of a coronavirus. SARS spread rapidly in 2002–2003.

The new strain of coronavirus is called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus causes coronavirus disease 19 (COVID-19).


Around 80%Trusted Source of people with COVID-19 recover without specialist treatment. These people may experience mild, flu-like symptoms. However, 1 in 6 peopleTrusted Source may experience severe symptoms, such as trouble breathing.

The new coronavirus has spread rapidly in many parts of the world. On March 11, 2020, the World Health Organization (WHO)Trusted Source declared COVID-19 a pandemic. A pandemic occurs when a disease that people are not immune to spreads across large regions.

It’s okay take a deep breath . Yes, it’s a lot to take in but we all know how china played with the whole world .

The protocols.

  • Wear masks ,
  • Wash hands ,
  • Use sanitizers ,
  • Social distancing , etc,.

Is it important to follow protocols ?

You say NO , I say ‘if you want to die you can easily ignore the protocols ’ . Well I don’t want to die , I have my whole 20s , 30s and so on…… .

According to the survey, people have been moving around freely, meeting different social groups and attending gatherings, going to malls and markets. This indicates that a pandemic fatigue has set in after after a year of restrictions on movement, social distancing and strict mask wearing norms.

Well , if you are saying this is what following protocols is than I am happy to stay home rather than chilling around like a monkey . Like really , a monkey also has a common sense that when to do chilling and when to fight for himself . What we are doing is putting masks in our pocket to showcase the world that I have one . Haha it’s kinda funny .

We long to return to normal, but **normal led to this**. To avert the future pandemics we know are coming, we MUST grapple with all the ways normal failed us. We have to build something better. I hope this piece, in showing what went wrong, helps.

Cabinet Reshuffle

With number of changes taking place in the country in recent times, one of a major change is taken place in the union cabinet. The Modi government had introduced new members in the council giving rise to a whole new cabinet of ministers for different departments on July,7th 2021. The total members counted as 43 among which 36 are new faces and 12 had been dropped out from the cabinet which includes, Health Minister Harsh Vardhan, IT and Law Minister Ravi Shankar Prasad and I&B Minister Prakash Javadekar, and brought Sarbananda Sonowal, Narayan Rane, Jyotiraditya Scindia and others. Many prime ministers all over the world have been known to have sacrificed this or that ministerial pawn in order to cover up their own leadership failure. Harsh Vardhan’s departure is as close an admission of governmental floundering as prime ministerial hubris would allow.

The new department of cooperation is granted to our home minister Amit Shah. New list is as follows-

Rajnath Singh: Defence Minister, Nitin Gadkari: Road Transport and Highways Minister, Nirmala Sitharaman: Finance Minister, Corporate Affairs Minister, Narendra Singh Tomar: Agriculture and Farmers’ Welfare Minister, S Jaishankar: External Affairs Minister, Arjun Munda: Tribal Affairs Minister, Smriti Irani: Women and Child Welfare Minister, Piyush Goyal: Commerce & Industry Minister, Consumer Affairs Minister, Food & Public Distribution Minister, Textiles Minister, Dharmendra Pradhan: Education Minister, Skill Development and Entrepreneurship Minister, Pralhad Joshi: Parliamentary Affairs Minister, Coal Minister, Mines Minister, Narayan Rane: Micro, Small and Medium Enterprises Minister, Sarbananda Sonowal: Ports, Shipping and Waterways Minister, AYUSH Minister, Mukhtar Abbas Naqvi: Minority Affairs Minister, Dr Virendra Kumar: Social Justice and Empowerment Minister, Giriraj Singh: Rural Development Minister, Panchayati Raj Minister, Jyotiraditya Scindia: Civil Aviation Minister, Ramchandra Prasad Singh: Steel Minister, Ashwini Vaishnaw: Railways Minister, Communication Minister, Electronics & IT Minister, Pashu Pati Kumar Paras: Food Processing Industries Minister, Gajendra Singh Shekhawat: Jal Shakti Minister, Kiren Rijiju: Law & Justice Minister, Raj Kumar Singh: Power Minister, New & Renewable Energy Minister, Hardeep Singh Puri: Petroleum & Natural Gas Minister, Housing & Urban Affairs Minister, Mansukh Mandaviya: Health and Family Welfare Minister, Chemicals & Fertilisers Minister, Bhupender Yadav: Environment, Forest & Climate Change Minister, Labour & Employment Minister, Mahendra Nath Pandey: Heavy Industries Minister, Parshottam Rupala: Fisheries, Animal Husbandry and Dairying Minister, G Kishan Reddy: Culture Minister, Tourism Minister, Minister for Development of Northeast, Anurag Thakur: Information & Broadcasting Minister, Sports & Youth Affairs Minister. Other 28 will hold the charge as Ministers of State.

This new cabinet marked a starting of new journey not only in terms of development but also along with growth with social equality as the members itself are chosen from different social backgrounds including, 12 ministers from Scheduled Caste communities from states such as Tamil Nadu, Rajasthan, Karnataka, Uttar Pradesh, Madhya Pradesh, West Bengal. Two of them are likely to be Cabinet ministers. From the Scheduled Tribe communities, eight representatives from Arunachal Pradesh, Jharkhand, Chhattisgarh, Odisha, Assam, and Madhya Pradesh are inducted. Three of these are Cabinet ministers. Also, 19 members from Other Backward Class (OBC) communities. 11 women members had aslo been accomodated giving rise to women empowerment.

According to people aware of the details, the selection of ministers has also been done with the intent of bringing on-board people with administrative experience as the government has faced criticism including over the state of the economy, job crisis, rising prices, and the response to the second Covid-19 wave.

Crisis in LAKSHADWEEP( A union territory)

There were many hashtags trending, regarding the Lakshadweep issue on twitter and Lakshadweep has been spotted on several social platforms for the past days. Some were wondering what was happening in Lakshadweep and what has triggered the ongoing hassle to protect the island from social and political turmoil and imminent ecological demolition. In brief let us see what has pushed Lakshadweep into such a devastating state.

Lakshadweep is the India’s smallest Union Territory consisting a chain of 36 individual islands located in the Arabian Sea about 400 km from the city of Kochi with an area of 32 sq km. It comprises of 12 atolls, three reefs, five submerged banks and ten inhabited islands. The inhabited islands have a population of nearly 64,473 people according to the 2011 census. Culturally and socially the inlands’ are close to Kerala and the people over there speak a dialect of Malayalam with the influence of Arabic similar to Arabi Malayalam, in the Minicoy island which is close to the Maldives the language spoken is Mahl. Lakshadweep is known for its exotic and alluring beaches and the exuberant green landscape. In Malayalam and Sanskrit the word Lakshadweep means ‘a hundred thousand islands.’ When some of the beaches in the country are swamped with air pollution, plastics and wastes, it is pertinent to mention that the natural landscapes, the heavenly atmosphere, the glittering sea, the peace living people, the sandy shores, abundance of flora and fauna and the deprivation of a rushed and hasty lifestyle enhances the charisma of Lakshadweep. It certainly holds the the least position in crime rate of the country and one of the lowest, globally as well. As per the national crime records bureau (2019) report the island had zero cases of major crimes such as rape, murder, kidnapping and dacoity. The inhabitants take pride in their traditional culture while maintaining prominent environmental measure to safeguard the island. We can describe it as a small heaven on earth for its resources and wealth. It is a restricted territory and one requires an entry permit issued by the Lakshadweep Administration to visit the islands because 94% of the population are scheduled tribes.

The islands are protected under special provisions where alcohol and liquor sales are not permitted, and the non residents cannot buy any land. As Lakshadweep is a union Territory it doesn’t have a formal Chief Minister as other states do but for the administration and monitorization an administrator like an IAS or IPS officer would be appointed by the President. The trouble began after the death of Dineshwar Sharma, the former Administrator of Lakshadweep and once Praful Khoda Patel took over charge as the new administrator. He was a former BJP leader and the former Home Minister of Gujarat. After Praful Khoda Patel took charge, he came up with many drafts of several reforms such as the Lakshadweep Animal preservation regulation that bans slaughter of cows,bulls and bullocks( This proposal was fiercely opposed alleging that Patel is implementing the RSS’s agenda of beef ban) Lakshadweep prevention of Anti-Social Activities Regulation, Lakshadweep Development Authority Regulation( The draft bill is been widely resented with protestors alleging this law is aimed at serving ”Real estate interests” and usurping the small land holdings of the people) and amendment to the Lakshadweep Panchayat Staff rules(The draft proposed that if a resident has more than two children he/she cannot contest a panchayat election). The draft regulation defines development as the carrying out of building, mining, quarrying or other operations so it becomes apparent that the regulations make it very easy for the government to take over land of any person in the garb of development. When the nurses and health care workers protested for the salary hike everybody were refrained form their jobs and arrested. The Muslim majority island territory has remained a non alcoholic zone for decades but there was another draft framed that allowed sale of liquor at hotels and resorts in the name of tourist promotion.

The development authority regulation appears to be quite a controversial reform and hundreds of the islands’ residents have written to the administration opposing it. They expressed their intimidation that Patel’s motive was to destroy traditional and the cultural diversity of the people of Lakshadweep. Praful Patel was involved in many controversial circumstances. To everyone’s astonishment, when the whole world was inflicted by corona, Lakshadweep had no cases of Corona till last December. But after Patel took charge he pronounced that the people who tested negative for Corona within 48 hours can arrive to Lakshadweep and opened the gate for outsiders. But today Lakshadweep has over 7000 cases of covid-19 and corona is been spreading. Services of hundreds of contract laborers working under various departments of the Union Territory have been terminated and workers of various government offices have been dismissed. These are some of the woeful situations that the Lakshadweep is into and has got trapped in a contentious and autocratic administration. Development of a territory is most welcomed by the people but it should not ruin the resources and the wealth of the space.

Covid-19 THIRD WAVE.

Raising the alarm bells for policymakers and citizens, a research report has contended that India may witness the third covid wave from August 2021. The report – COVID-19: The race to finishing line – prepared by SBI Research, claims that the covid third wave peak will arrive in the month of September 2021.

The research report says that India achieved its second wave peak on 7th May. “Going by the current data, India can experience cases around10,000 somewhere around the 2nd week of July. However, the cases can start rising by the second fortnight of August,” the report said.


These are the highlights from the report:

1. Global data shows that on average third wave peak cases are around 1.7 times the peak cases at the time of second-wave.
2. However, based on historical trends the cases can start rising by the second fortnight of Aug’21 with peak cases at least a month later.
3. India has started giving more than 40 lakh vaccination doses per day as shown by 7 DMA.
4. Overall, India has fully vaccinated 4.6% of its population, apart from 20.8% having received one dose. This is still lower than other countries including the US, the UK, Israel, Spain, France among others.
5. The decline in bank deposits in FY21 and concomitant increase in health expenditure may result in further increase in household debt to GDP in FY22.
6. States with high per capita GDP have been associated with higher Covid-19 deaths per million while low per capita GDP are associated with low Covid-19 deaths.
7. Only 4.6 per cent of the population in India is fully vaccinated, while 20.8 per cent have received one dose, much lower compared to other countries including the US (47.1 per cent), the UK (48.7 per cent), Israel (59.8 per cent), Spain (38.5 per cent), France (31.2), among others.

However, these positive emotions last only for a brief period and in order to fully experience its benifits, it is necessary that these positive thoughts be thought often.

Negative thinking can feel outside of your control and completely automatic. Fortunately,research and studies have come up with great ways with whose help you can break the habit of negative thinking and develop a more positive outlook towards life.This practice of overcoming negative thoughts has been studied and proven and has helped many individuals change their lives.

Given below is a list of these effective ways that can help you alter your thought pattern and learn to handle your negative thoughts in a positive way.

1)Be conscious of your thoughts:

As soon as you find yourself thinking a negative thought,stop yourself from thinking it.

One thought can lead to another and before you know you are experiencing deep grief and sorrow over your past mistake or hurts.

It is therefore important you stop at that very first negative thought itself. The next thing you can do is replace it with a postive thought or reframe your thought pattern into a positive one.Doing this will help you feel more positive and helpful.

2.keep youself Busy:

“An idle mind is the devil’s workshop” is a very true saying when it comes to negative thoughts.If you notice,you are more prone to negative thinking when you are sitting idle,rather than when you are busy.

According to research ,keeping your hands and mind occupied by doing tasks like cleaning, sorting, knitting etc., helps keep your mind off negative thoughts. Mainly keeping busy is associated with a battery of brain benefits.

This is because the busier you are the lesser time you have to devote to negative thoughts.

3. Avoid Triggers:

It is very easy to fall into the rut of negative thinking.That’s why it is important that one pay attention to their environment and intentionally remove all triggers that would initiate negative thoughts.

It could be a gift from an ex or a picture or a friend or a neighbour or a relative who might be the constant source of negative thoughts in your life.

According to some researchers,negative thinking is also a habit that one can easily pick up from others.Minimizing contact with such people and avoiding negative triggers can help keep you sane and positive.

4. Sufficient Rest and Sleep:

Lack of sleep greatly affects your mood,causing you to feel anxious, irritable and angry.Getting the sufficinet 8 hours of sleep helps keep the negative thoughts away and greatly improves your mental health.

Psychologists state that there is an important relationship between sleep and mood.

Economic significance of Algae

People are mainly aware about the algae as seaweeds or algal blooms. They are the organisms with ability of photosynthesis and very much diverse community as well. But algae are important to man and their economic importance is manyfold. They are used as food, fodder and manure. They are also important in industrial field as well as agriculture.

there are 7 major types in algae
  • Chrysophytes
  • Euglenophytes
  • Pyrrophytes
  • Chlorophytes
  • Rhodophytes
  • Phaeophytes
  • Xanthophytes
these are the benificial roles of algae
  1. Algae is a food source: In different parts of the world algae have been utilized as direct source of food. They are rich in proteins, carbohydrates, oils, vitamins and minerals hence used as a diet food. They possess minerals like Cu, Fe, Zn, Co, V, Mn and Cr. About 20 different seaweeds are used as food source. Nostoc,
  2. Algae as fodder: Many seaweeds are as food for cattle, poultry and aquatic organisms. Sargassum is used as cattle feed in China. Laminaria and Fucus are also used for the same purpose. Seaweed meal increases the egg laying capacity of fowls. These eggs contain high amount of iodine and carotene.
  3. Algae in agriculture: Algae are used as green manures in agriculture. Sargassum, Laminaria, Macrocystis and Gracilaria are the most commonly used ones. Seaweed manure increases the yield of barley, potato, coconut palms, citrus etc. Many blue green algae have the ability to fix the atmospheric nitrogen into the soil. So they can be used as biofertilizers. Saline and alkaline soils can be converted into productive ones by growing some blue-green algae on soil. Anabaena, Rivularia, Spirulina are used for this purpose.
  4. Algae in Industries: In Industries many algae have been used as sources for the extraction of commercial products like agar-agar, diatomite, carrageenin and algin. Agar-agar is used as culture media for bacteria. It is also used as emulsifier in ice-cream, fruit jellies and dairy product preparation. Algin is used as painting pastes in textile industry and thickeners in cosmetics, pharmaceutical products etc. Carrageenin which is extracted from Chondrus crispus and Gigartina are used in food industry, textiles and leather industry. It is a remedy for cough.
  5. Algae in sewage disposal: Sewage water contains organic and inorganic substances which makes it low in oxygen content. But sewage finds use in agricultural practice as they are rich in salts. To decrease the foul smell algae are used. Algae are used to decompose the organic and inorganic substances.
  6. Algae and Research: Algae are used in the study of effects of pesticides, herbicides and UV light. They are used in the research for preparing biofuels.
  7. Algae as pollution indicator: Some algae grow well in polluted water as they are more tolerant towards pollution. Growth of these algae indicates the pollution and its intensity. Scenedesmus indicates copper wastes and Ulothrix zonata indicates indicates paper mill wastes.

Though many algae are useful, there are harmful algae are also there. The development of water blooms is considered to be a bad effect of algae. There are some parasitic algae cause diseases in plants. Attachment of algae tp ship retards the speed of the ship. growth of algae on cloths are also seen and they ruin the cloth.

UNIX

UNIX Full Form - GeeksforGeeks

UNIX is a multi-user and multitasking operating system. in a multi-user environment. the computer can receive the commands from a number of end users programs, access files, and print documents simultaneously.

The host computer, which has a UNIX operating system, provides services to the terminal, such as file access services. four terminals are connected to one host computer and all the terminals are sharing resources from the host computer.

Features of UNIX

The general and additional features of UNIX operating system are :

  • File and Processes : file and process are two entities that are supported by UNIX. A file contains information, such as text, code or directory structure that you need to save in the computer, The file is stored in the hard disk of the computer at a particular location, which can be easily remember whereas a process is the name given to a file or a programs that is currently running . UNIX provides various tools that enable you to control a process, change the sequence of the process, and kill the process.
  • Multi-user system: UNIX supports multitasking system as the kernel is designed to handle multiple processes. A single user can run multiple process simultaneously. For example, an end user can print a file and edit another file simultaneously. The kernel handles the multiple processes as foreground and background process. The current process runs in the foreground and the other processes run in the background. This multitasking feature is an advantage for the programmers, as they do not have to close the editor and run the program; this can done simultaneously.
  • UNIX toolkit: The UNIX toolkit provides various tools that are enable you to perform different tasks in UNIX as kernel alone cannot perform every task. The tools that are included in the UNIX toolkit are:

1:- General purpose tools , such as vi editor

2:- Text manipulation utilizes filters that are used to retrieve the output from two or more commands simultaneously .

3:- Compiler and Interpreter .

4:- Network administration and system tools , such as mailx and pine.

  • Pattern Matching :- UNIX supports pattern matching feature that enables you to retrieve the output according to the required pattern . Pattern matching in UNIX can be implemented using a special characters , such as * known as metacharacter .
  • Programming Facility :- UNIX provides a programming facility known as shell that is developed specifically for programmers and not for the users .

Environmental pollution

“Humankind has not woven the web of life. We are but one thread within it. Whatever we do to the web, we do to ourselves. All things are bound together. All things connect.”

~ Chief Seattle

What is environmental pollution ?

Is it degrading our lifestyle ?

How can we improve our environment ?

Let’s get through the topic .

Introduction

One of the greatest problems that the world is facing today is that of environmental pollution, which is causing grave and irreparable damage to the natural world and human society with about 40% of deaths worldwide being caused by water, air and soil pollution and coupled with human overpopulation has contributed to the malnutrition of 3.7 billion people worldwide, making them more susceptible to disease.

Environmental pollution is defined as “the contamination of the physical and biological components of the earth/atmosphere system to such an extent that normal environmental processes are adversely affected.”

From: Environmental Management, 2017

We all are well known about the word Environmental pollution . It is not some kind of new phenomenon , yet it is a greatest problem facing by our society . Still , people are avoiding the topic to its utmost.

Environmental pollution is one of the most serious global challenges. Wild-type organisms have a slower degradation rate of hazardous materials.

Both developed and developing nations share this burden together, though awareness and stricter laws in developed countries have contributed to a larger extent in protecting their environment.

Reasons behind environmental pollution

  • The Burning of Fossil Fuels. Industrial Emission.
  • Indoor Air Pollution.
  • Wildfires.
  • Microbial Decaying Process.
  • Transportation.
  • Open Burning of Garbage Waste.
  • Construction and Demolition.
  • Urbanization and industrialization. Since the era of industrial revolution, man has continued to introduce hazardous materials into the environment at an alarming rate.Mining and exploration.
  • Agricultural activities.
  • Particulate matter.
  • Plastics.
  • Energy production.
  • Deforestation.
  • Mining.
  • Over population.
  • Increase in global average temperature.

Effects of environmental pollution

Environmental pollution is an incurable disease . It can only be prevented.

Barry commoner

1. Effects on Humans. The effects of environmental pollution on humans are mainly physical, but can also turn into neuro-affections in the long term. The best-known troubles to us are respiratory, in the form of allergies, asthma, irritation of the eyes and nasal passages, or other forms of respiratory infections. Other rarer diseases include hepatitis, typhoid affections, diarrhea, and hormonal disruptions.

2. Effects on Animals . Environmental pollution mainly affects animals by causing harm to their living environment, making it toxic for them to live in.

3. Effects on plants . As for animals, plants, and especially trees, can be destroyed by acid rains (and this will also have a negative impact on animals as well, as their natural environment will be modified), ozone in the lower atmosphere block the plant respiration, and harmful pollutants can be absorbed from the water or soil.

Solutions for environmental pollution.

  • Evironment planning.
  • Shifting to eco-friendly transportation.
  • Air pollution must involve moving away from fossil fuels, replace them with sustainable fuels .
  • Solar power .
  • Wind power.
  • Go green.
  • Storage facilities for solid waste.
  • Environmental friendly products.
  • Policies implimentation for environmental pollution.
  • We also need to work on electromagnetic radiation (ER) reduction.
  • Awareness through mass media.
  • More green parks and areas.
  • Environmental education, etc,.

Math 2.0 day

Today is math 2.0 day, but what exactly does that even mean?.With or without knowing we all use math several times every single day. The subject is also important for the advancement of technology. And thus, to celebrate the combination of maths and technology, Math 2.0 Day is celebrated on July 8. Read on to know other details.

Imagine the way the world used to be viewed! Math as known to be important but not thought to be something you could make a living at and the rising tide of technology was considered a fad! Math 2.0 Day reminds us that technology is here to stay!

Every year, Math 2.0 Day is celebrated on July 8. The day is observed to highlight the importance of the combination of maths and technology. The day was formed to celebrate the achievement made through the combination of maths and technology. Math 2.0 Day also helps to educate the masses about the benefits of maths and technology. Without maths and technology, it would have been impossible for us to achieve the various entertainment mediums we have now.

History of Math 2.0 Day

In 2009, the Math Interest Group formed Math 2.0 Day. Math is extremely important for the advancement of science, technology and education.Math 2.0 Day is a celebration of the blending of technology and mathematics. For a lot of us, math wasn’t a favorite subject, we’d spend the entire period staring at the equations and wondering what sort of livid madman designed these torture chambers on paper. Ultimately, however, we realized that math is utterly indispensable in our modern world. If you’ve ever wondered who uses math in their day to day careers, you aren’t alone and we have some answers for you.

Programmers deal with mathematics every day, as it’s the framework upon which all computer operations are formed. Everything from the order of operations to quadratic equations is necessary to make even the simplest program. Scientists are one of the biggest users of mathematics, whether they’re calculating the statistical variance of their data or figuring out how much to add to their chemistry experiment, it’s involved at every step.

One presumes you live in a house, drive a car, or operate a computer? The engineers responsible for designing those things so that they work, and especially in the case of the house, use math to ensure it doesn’t come crumbling down on your head. Math 2.0 day celebrates all these mathematical heroes and more.

How to celebrate Math 2.0 Day

If you’re like me, you probably have your old math books from college laying around. I suggest busting them open and studying them again. Who knows, in the intervening years you may have secretly developed a love for those dancing numbers. If not, make sure that you stop by those people who use math every day and thank them for doing the work so you don’ thave to.Mathematics is one of the most important fields in the world today, and just about everything we know and love is built on its back.

Asset Bubble

What Is a Bubble?

A bubble is an economic cycle that is characterized by the rapid escalation of market value, particularly in the price of assets. This fast inflation is followed by a quick decrease in value, or a contraction, that is sometimes referred to as a “crash” or a “bubble burst. Typically, a bubble is created by a surge in asset prices that is driven by exuberant market behavior. During a bubble, assets typically trade at a price, or within a price range, that greatly exceeds the asset’s intrinsic value (the price does not align with the fundamentals of the asset).The cause of bubbles is disputed by economists; some economists even disagree that bubbles occur at all (on the basis that asset prices frequently deviate from their intrinsic value). However, bubbles are usually only identified and studied in retrospect, after a massive drop in prices occurs.

How a Bubble Works

An economic bubble occurs any time that the price of a good rises far above the item’s real value. Bubbles are typically attributed to a change in investor behavior, although what causes this change in behavior is debated. Bubbles in equities markets and economies cause resources to be transferred to areas of rapid growth. At the end of a bubble, resources are moved again, causing prices to deflate.

The Japanese economy experienced a bubble in the 1980s after the country’s banks were partially deregulated. This caused a huge surge in the prices of real estate and stock prices. The dot-com boom, also called the dot-com bubble, was a stock market bubble in the late 1990s. It was characterized by excessive speculation in Internet-related companies. During the dot-com boom, people bought technology stocks at high prices—believing they could sell them at a higher price—until confidence was lost and a large market correction occurred.

The research of American economist Hyman P. Minsky helps to explain the development of financial instability and provides one explanation of the characteristics of financial crises. Through his research, Minsky identified five stages in a typical credit cycle. While his theories went largely under-the-radar for many decades, the subprime mortgage crisis of 2008 renewed interest in his formulations, which also help to explain some of the patterns of a bubble.

Displacement

This stage takes place when investors start to notice a new paradigm, like a new product or technology, or historically low interest rates. This can be basically anything that gets their attention. 

Boom

Prices start to rise. Then, they get even more momentum as more investors enter the market. This sets up the stage for the boom. There is an overall sense of failing to jump in, causing even more people to start buying assets. 

Euphoria

When euphoria hits and asset prices skyrocket, it could be said that caution on the part of investors is mostly thrown out the window. 

Profit-Taking

Figuring out when the bubble will burst isn’t easy; once a bubble has burst, it will not inflate again. But anyone who can identify the early warning signs will make money by selling off positions. 

Panic

Asset prices change course and drop (sometimes as rapidly as they rose). Investors want to liquidate them at any price. Asset prices decline as supply outshines demand.
