Primary Energy
Primary energy is the energy as it is available as resources – such as the fuels that are burnt in power plants – before it has been transformed. This relates to the coal before it burned; the uranium; or the barrels of crude oil. This is the most widely available statistic and very commonly used PE.

Secondary Energy
When we convert primary energy into a transportable form we speak of secondary energy. For example, when we burn coal in a power plant to produce electricity, electricity is a form of secondary energy. Secondary energy like liquid fuels (gasoline, petrol and diesel: which are refined oil), electricity and heat.

Final Energy
Once we’ve transported secondary energy to the consumer it is final energy. Final energy is what a consumer buys and receives, such as electricity, heating, or petrol, diesel at the fuel pump.

Useful Energy
This is the last step. It is the energy that goes towards the desired output of the end-use application. For a lightbulb, it’s the amount of light that is produced, Fan, AC, fridge, collar use electricity to cool. For a car, it’s the amount of kinetic (movement) energy that is produced from oil.

For answering this I am dividing AC into two parts. The one that fits on the window (window type), and the one that fits on the wall (mini-split). The first is one piece, the second is two pieces (split)–one part is outside the wall, and the compressor (detailed below) is outside. The faucet hinges on the window AC are all in the same box, but the compressor is on the outside, not the room. But both types of AC basically work in the same way.
How does AC work?
Seen to pick up water with clothes from the floor? Or seen mopping the floor?
There is water on the floor, a cloth absorbs the water, then the cloth is crushed/wrung out to remove the water.
For AC, the water is the heating of the house, the cloth is a kind of chemical, which is called refrigerant.
The refrigerant absorbs the heat, then the refrigerant is crushed/twisted to expel the heat from the refrigerant outside the room. A machine called a ‘compressor’ works to compress/compress the refrigerant. As the name suggests, it compresses. By the way, the fridge works the same way.
Refrigerant is in liquid and gas state in different parts of AC. By absorbing heat, it becomes a gas, compressed in a compressor and becomes a liquid again.
– We all understand that when gas pressure increases, pipes can burst.
— If the pipe is blocked/narrowed for any reason, the pressure may increase
— Pipes can burst even if the dirt accumulates around the overheating.
The compressor can also burst due to the same reason. If the compressor of the mini split bursts and can injure people on the street below, it will not break through the walls and enter the house. A window-type compressor rupture can injure people below and people in the house, but injuries inside the house are less likely.
The mini split has a gas pipe (coil) inside, so it can crack but not explode.
Rupture from such causes is rare. The rate at which news reaches Bangladesh is ridiculously rare.
How much damage can a metal pipe or compressor crack? The damage is much less than if you hit a brick wall with all the force of another brick, because the broken pieces weigh so much less. However, a direct hit to the human body by metal fragments can cut, and can be fatal. It is not impossible to enter by breaking the glass of the window.
But again, it cannot break the wall.
Q: Can AC gas cause a fire?
Answer: Not possible. Common refrigerant gas can suffocate people, but it does not catch fire like stove gas. But there is a “but”.
There is a refrigerant called R-22a, which is a mixture of LPG and butane (cigarette lighter gas). It catches fire very well.
Couldn’t find if R-22a is sold in Bangladesh.
If the R-22a continues to leak, it may catch fire due to an electrical short circuit or other cause.

Are you worried about the future of Bangladesh?

While Israeli university students discover new elements, our university students visit the library and fall in love! The world’s number 1 Harvard University has no concerts reported throughout the year. And how many concerts in our varsity… L.R.B., James, Untitled, Ashes, Tahsan, Wharfage.- one program after another.
Dance, song, and Holi festival are also now. Fak u, hot baby, crush khaichi, masti, yaba, gaza these words are now very familiar to boys and girls.

In other countries, learned people, scientists come to the university to speak. Scientist Einstein participated in debates at Oxford University several times.
And us?

Scientist Moksudul Alam went to many convocation ceremonies? How many convocations did our current scientist Muhammad Ashraful Alam attend? (Who developed the bacteria detection sensor. His research was published in the journal “Proceedings of the National Academy of Sciences of the United States of America”)
The three researchers of Bangladesh have achieved unprecedented success in diagnosing ‘gene’ defects. They are — Dr. KM Forkan Uddin and Dr. Md. Robed Amin and Bangladeshi-born Canadian scientist Dr. Mohammad Uddin Dafil. Will they also go to a university convocation ceremony? Will they be called to any university in Bangladesh?

None of them will be called to the university. Because – Naila Naeem and Sunny Leone are expensive here or spineless intellectuals carrying the seeds of brokering and slavery – who want to make the people of this country like Rohingyas. Steve Jobs’ speech is available on YouTube. He addressed the convocation.
Bill Gates is a good speaker.

Mark Zuckerberg is also a motivational speaker!
Today, China is becoming one of the world’s superpowers. India is dominating the IT sector. Their sons and daughters work at Google. And our university boys do masti and girls pass the time by watching Hindi serials.

While India is sitting and producing CEOs, we are sitting and producing cadres on campus. While America designs new fighter jets, Turkish university students organize defense-security fairs, we protest the Mithila-Tahsan divorce on campus and watch lol videos on YouTube.

While Myanmar is trying to invent mineral resources across its borders – our children are making love in the botanical garden.

In our country, the boy who became a hit with a love drama is a big celebrity. And Maida Sundari is hot cake.

Here’s a video of an intimate visit to the library leaked.
A teacher who recently returned from abroad told us that the skills of college level boys and girls in our country are not so creative and efficient.
We are spending billions of rupees per month to connect more than 100 TV channels (not even one of our channels are shown in India) to educate students.

How to pick up a girl during office hours.
How to propose to a best friend
How to flirt with a friend’s girlfriend.
Why not make researchers from Bangladesh?
Why we do not get a place in the world ranking?
Why we do not have any international celebrities?

There are bars to love, sea beaches, long drives. University library is not a place of love! This is not the place to watch Hindi channels! Not everyone needs to go to university.

University is a place to acquire skills. Myanmar has imposed 1 million Rohingyas on us, India is organizing to smuggle 80 million Bengali Muslims from Assam into my country! If India makes nuclear bomb – will we make hydrogen bomb or not?

How to get rid of the communalism and hegemony of neighboring states? How will our defense policy with China? Even if our university boys and girls have no idea about these things – getting golden A+ in exams by out-questioning, spending all night with girlfriends on the internet, the hegemonists have managed to insert the steps to make the nation spineless!

As a entrepreneur I still experimenting with different things. I can proudly say that a lot of my products and services have failed. Yes. I failed.
I can also proudly say that a few of my products have succeeded, some above my expectations.

The success sometimes gives birth to some form of ego. The failures, on the other hand, gave birth to a new character inside me. They taught me things I could never have learned from the best university of the world, or from the best books or courses.
If you have an idea or theory, try putting it into practice. Successful hole try to remain humble and make your product better. Failure hole be proud, because its the first step of something big

An important component of our fourth industrial revolution is the creation of skilled manpower. A Startup zone, idea/innovation zone, industry-academic zone, brainstorming zone, e-library, Bangabandhu corner, exhibition/demonstration center, video conferencing room, etc. have been placed in this incubator to create skilled manpower. In addition to encouraging the young society of the country in the information technology sector, they will play an important role in making themselves experienced by combining academic knowledge with real life in this sector.

It is said that data science will lead the world in the next decade. The more advanced the workforce is in data collection and processing, the more advanced they are in leadership. In this regard, so that the youth of our country does not lag, the data center, and research lab has been kept in this incubator. Which will advance the data science of our country in the fourth industrial revolution.

CUET IT Business Incubator Project
This business incubator was set up in CUET to create successful entrepreneurs in the country’s information technology sector, encourage research and innovation activities and strengthen industry-academic collaboration, as well as expand Bangladesh’s opportunities globally in the information technology sector. The project was implemented at a cost of around 117.7 million takas under the supervision of Bangladesh Hi-Tech Park Authority under the Department of Information and Communication Technology.

It is to be noted that this incubator is expected to play a role in the construction of ‘Smart Bangladesh’ by 2041 by producing skilled graduates in the information technology sector to meet the challenges of the fourth industrial revolution.

Which is in the IT Business Incubator
Under the Sheikh Kamal IT Business Incubator Project, this incubation building with a 50 thousand square feet area and 10 floors has been constructed on about five acres of land inside CUET Campus. Besides, a multipurpose training building with six floors of 36 thousand square feet has been constructed. Incubation buildings include – Startup Zone, Idea/Innovation Zone, Industry-Academic Zone, Brainstorming Zone, e-Library, Data Centre, Research Lab, Bangabandhu Corner, Exhibition/Demonstration Centre, Video Conferencing Room, Meeting Rooms, etc.

An artificial intelligence (AI) lab, a machine learning lab, a big data lab, an optical fiber backbone, a sub-station, and solar panels have been placed to facilitate the work of entrepreneurs and researchers. Besides, there are separate corners for banks and IT firms, cyber cafes, food courts, cafeterias, recreation zone, maker spaces, display zone, press/media coverage zone, own parking facilities, etc.

On the other hand, the multipurpose training building has a well-equipped auditorium with a capacity of 250 people and eight separate computer lab cum seminar rooms with a capacity of 30 people. Besides, two separate (female and male) residential dormitory buildings of 20,000 square feet each has been constructed. Each dormitory has 40 rooms. Besides, a state-of-the-art research lab with two mini supercomputers is going to be set up soon.

Although student life and journalism are two separate lives, campus journalism brings these two into the same lifestyle, and campus journalists face a new reality. In the case of campus journalists at the University of Engineering, the experience is somewhat different. Because this is represented by the students of the journalism department in public universities, those who have academic studies in journalism and choose journalism as a profession in their later life. Journalism is a completely different and new experience for engineering students there.

Many times the teacher to whom I do my academic classes, some of the news I write goes against him. However, I have to advance my academic life with him. From that point of view, there is institutional pressure in campus journalism. The same phenomenon can be repeated for friends. Campus journalists have to take a certain time outside of classes, tests, labs, assignments, or thesis work to monitor and save information on the current situation on campus. Also, according to the current situation in Bangladesh, campus journalists have to face various problems like the non-tolerant, reckless behavior of various student organizations in the campus. Since campus reporter has to be based on the campus they report on, crime-related reports naturally become riskier. Due to all these issues, the campus life of campus journalists becomes difficult at times.

University Vice-Chancellors, Registrars, Student Welfare Offices, Deans, Teachers, Treasurers, Controllers of Examinations and other administrative officers want to hide their weaknesses, errors, and inefficiencies. On the other hand, the ruling student organizations want to hide their incidents like extortion, tender-betting, student torture, drug distribution, and open weapons drills from the people of the country. But when these issues came to the fore after the campus journalist published the news, there were various threats, threats, torture, attacks, etc. And ignoring these, campus journalism has to continue. Also, there is fear of undisclosed harassment by the university administration, loss of studentship.
Among these, there are some responsible people in the administration and surroundings, who understand the responsibility of a campus journalist. They never see a campus journalist in a negative light even with the news that goes against them because they can understand the responsibility on the relationship and everything.

In obstacles and adversities, I have to ensure the truth of what I am writing.

When an uncharged or uncharged object is brought in contact with or near a charged object, the uncharged object becomes charged. Just like when an iron is brought near a magnet, the iron also behaves like a magnet. This method of inducing an inert object by bringing it near to an inert object without touching it is called electromagnetic induction.

Generally, friction occurs between two objects. Again, if the infected object is brought in contact with the uninfected object, the uninfected object is infected. Because in this case, some charge from the charged object goes to the uncharged object. But in this process, the uninjured object is not brought into contact with the infested object but only when it is brought close to it.

Amedeo Avogadro’s hypothesis is also called Avogadro’s hypothesis despite being a proven theory. There is no logical reason behind it. While Avogadro could not prove his hypothesis theoretically, it was not fully accepted but could be used to arrive at the correct solution. At that time this unproven hypothesis was widely discussed as Avogadro’s hypothesis. It was later proved by Millikan, but its hypothesis remains. But you can call it theory or formula if you want. Rather that is more acceptable.
