Nuclear Reactors INDEX Nuclear Reactor  Heat Generation Cooling Reactivity Control Xenon Poisoning Electrical Power Generation Type of Nuclear Reactors Nuclear Fuel Cycle Refueling  Nuclear Safety Nuclear Accidents  Advantages and Disadvantages  01. Nuclear Reactor   A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in marine nuclear propulsion.  The heat from nuclear fission is passed to a working fluid (water or gas), which runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear-generated steam in principle can be used for industrial process heat or for district heating 02. Heat Generation A kilogram of uranium-235 (U-235) converted via nuclear processes releases approximately three million times more energy than a kilogram of it burned conventionally (7.2 × 1013 joules

Occupational Respiratory Disease

Introduction and Causes Repeated and long-term exposure to certain irritants on the job can lead to various lung diseases that may have lasting effects, even after exposure ceases. working in a car garage, textile factory, or coal mine can expose a person to hazardous chemicals, dust, and fibers that may lead to a lifetime of lung problems if not correctly diagnosed and treated. Diagnosis  Diagnosis of Occupational lung diseases usually requires an initial chest X-ray or CT scan for a clinical diagnosis. In addition, various tests may be performed to determine the type and severity of the lung disease, including: Pulmonary function tests. Biochemical and cellular studies of lung fluids Measurement of respiratory or gas exchange function Examination of airway or bronchial activity   A microscopic examination from a biopsy or autopsy of tissue, cells, and fluids from the lung. Symptoms of an occupational lung disease Symptoms of occupational lung disease include Coughing Shortness o

Misunderstood

08 - October - 2022   Dear stranger, Been a while since I have talked to you. I had a lot going on for a while now, so here I am sitting with you, its been past 12 midnight quite a while ago.  I find the weather resonating with my heart, drizzles of sorrow fall from the dark midnight clouds. The strong winds of time make the drizzles confused. The dark clouds resembled my hopelessness, and the blankets covered for the warm touch of affection I never got to experience. Don't know how long I have been in this condition, but it seems just as the long rainy days make the ground messy, my founding memories have been just the same. Theirs a diary in my hand, a pen, and a cozy corner, just for me to enjoy the solitude. You know, I thought they understood me, I thought that opening up to them would make them understand me. I thought I could change their opinion but little did I know that their mind was not water, it was stone. The hardened stone that neither can be broken by words of tru

Threads and Relations

Threads  Threads; they form; they break; they morph; sometimes with a gradual pace and sometimes in a snap. Threads also connect and strengthen, like the relations between 2 people.     Threads and relationships, I believe are similar, just like the colors of connections drift with time, and alter with the aura of the environment. The threads also do the same, they fade away, and are also affected if not taken care of. With healthy boundaries, love, care, and a little bit of fun, the hues of the rainbow can also shine over the deteriorating relations and threads.

They can form under the naked eye, and freeze up like icebergs in the cold sorrowful winds of conversations. But there are also the eternally blissful warm connections, filled to the brim with deep affection and pure love. At first, there is an extremely thin pure white thread, but with time as you star
