Refrigerator and its working

Refrigerator Basic  working Principal: To understand how a fridge works, you have to take inspiration from the human body: when we sweat, sweat produces a feeling of cold when it evaporates, because it takes calories from our skin. For a refrigerator, it's basically the same thing: you force the liquid to evaporate so that it takes heat inside the fridge. The fluid first enters the evaporator . As it is a very thin tube, it goes drop by drop: the molecules disperse and the fluid becomes gaseous. Very cooled (-40 ° C), it seeks to warm up by absorbing the heat that is inside the refrigerator. Then the gas is again compressed and liquefied in the condenser (coil outside), where it releases the stored heat. At the end of this circuit, the liquid is dehydrated to rid it of water, air and the various impurities which it has picked up. Contrary to popular belief, the refrigerator does not "make" cold, but captures the heat inside the fridge . If the door is opened too

Lung Cancer Symptoms Causes Treatment

What is Lung Cancer? Lung cancer usually arises from the cells of the lower respiratory tract (bronchi). Therefore, it is also called bronchial carcinoma. Doctors distinguish between a small cell and a non-small cell form in lung cancer. Small cell bronchial carcinomas grow rapidly and often form metastases, i.e. daughter tumors in other organs. However, this form only occurs in 20 percent of the cases. Around eight out of ten patients have non-small cell bronchial carcinoma. Lung cancer is the second most common cancer among men in Germany and the third most common among women. According to the Center for Cancer Registry Data, around 53,000 people fell ill in 2012 ; men are affected more often than women. However, fewer and fewer men have contracted lung cancer since the 1980s, while the number of women is increasing. Experts attribute this to the fact that more women smoke today than in the past. Causes and risk factors: Smoking is the main risk factor: Tobacco smok

Stomach Cancer Symptoms Causes and Treatment

Stomach Cancer: The stomach cancer , also called gastric cancer , develops from a parietal cell (cell in the stomach wall), initially normal, that multiplies uncontrollably, forming a mass called a malignant tumor . More than 90% of the tumors that cause stomach cancer are adenocarcinomas , that is, they develop from the inner surface layer of the stomach, called the mucosa . It is a cancer which progresses slowly and which one seldom meets before 50 years. The tumors can remain local for a long time, before spreading to the other layers of the gastric wall and invading by contiguity the nearby organs (pancreas, colon, spleen) or by lymphatic and vascular way, by leaving cancer cells going to invade the lymph nodes, then spread these cancer cells to other organs such as the liver and lung (metastases). Other forms of stomach cancer , such as gastric lymphoma (which affects the lymphatic system), sarcoma (which affects muscle tissue) or gastrointestinal stromal tumor (which arises

Brain Tumor Symptoms Causes and Treatment

Brain Tumor: Brain tumors are caused by the growth of substances or abnormal cells that accumulate in or near the brain. Any brain cell can take the form of a tumor or a tumor Therefore, the nature of the disease depends largely on the size, location and type of tumor If the tumor is in a part of the brain that controls the human eye, a possible symptom may be blurred vision, but because the tumor can be in any part of the brain, it is difficult to estimate. How many of these symptoms are due to brain tumors? However, there are some signs that you should be aware of. Seizures The first symptoms appear in the form of seizures. These seizures have nothing to do with the type of tumor. Tumors cause inflammation in the brain and cause the brain to destroy neurons. There are also many types of seizures that affect the whole body or cause tremors in some parts. Persistent headache: Headaches are not the only sign of a brain tumor, but you should be careful if you have a persisten

Blood Cancer Symptoms and Treatment

Blood Cancer: Blood cell production and function are affected by blood cancer. Blood is produced in the marrow, where most of these cancers originate. Three types of blood cells that mature and develop from bone marrow stem cells are red blood cells, white blood cells, and platelets. The uncontrolled increase in an abnormal type of blood cell interrupts the process of normal blood cell development in most blood cancers. The functions of the blood, such as fighting infections and preventing serious air extraction, are restricted by these abnormal cancer cells (o). Three main types of blood cancer Blood cancer can be commonly divided into three types : 1) Leukemia 2) Lymphoma 3) Myeloma A factor named lymphocyte is a type of white blood cell that fights infection. Lymphocytes which are abnormal converted lymphoma cells, which multiply and surround in both lymph nodes and other tissues. Gradually, the immune system is worsened by these cancer cells. L

Cancer Treatment

Cancer Treatment:  Cancer is one of the fastest growing diseases in the world at the moment, but it can be cured if it is diagnosed early and therefore the death rate is very high. However, scientists have now discovered new immune cells that can kill most types of cancer and are expected to make significant progress in treating the disease. The scientists were looking at blood cells in a blood bank that have the ability to fight bacteria, and in the process they discovered a completely new type of T cells (immune cells). These new cells carry a receptor that ignores healthy cells and kills cancer cells. Research reports in the laboratory found that these new cells can kill cancerous cells in the lungs, skin, blood, colon, breast, bone, bladder, kidney and other types. Professor Andrew Sewell, who led the research team, said the discovery of such cells was "extraordinary" and would make a universal therapy possible, along with improving cancer-fighting therapie

Cancer and Its Symptoms

Cancer: Cancer is a group of diseases affecting an organism that is primarily related to cells. Cancer occurs when some cells in the body cannot continue to grow at a normal rate and begin to grow rapidly in size and size. Normal cells have a range of divisions at which they stop, and they also have a self-extinguishing system that causes the death of cells that contain a fragment of DNA. Death of this type of cell, which is either defective or out of date, is called programmed cell death. This process of normal cell division, inhibition of division and self-destruction is determined by genes. In contrast, cancerous cells are constantly dividing and their systemic cell death system  suicidal cells in the event of an irreversible disorder& also becomes defective and extinct. And when the growing number of cancer cells form a cluster, a body called a tumor begins to emerge. This inflammation also puts undue pressure on the normal cells around it and causes other disorders, such a

Kidney Stones Treatment

Kidney Stones:   Kidneys are very important for the human body. Every year, more than 50,000 people in the world die of various kidney diseases, due in large part to the lack of kidney donors. There are a lot of kidney diseases but one of major disease is kidney stone. Diet extra weight and diet can cause kidney stone . There are other causes but these are major causes. Kidney stones contain insoluble and solid minerals that accumulate in the kidneys, which interfere with the excretion of water from the body. These minerals are mostly composed of calcium oxalate but may also contain other compounds. These rock-shaped minerals can be as large as a golf ball and are small enough to be excreted in the urine. However, if they are large, they cause a lot of pain. A crystalline  solid is made up in kidney or urinary tract which causes troubles to human . symptoms and causes are written in other article on website you can check.

Kidney Stone Symptoms: Eyes swollen: One of the earliest symptoms of kidney failure is swelling around the eyes, indicating that a large amount of protein is being excreted from the kidneys through the urine. If this happens, the body gets adequate rest and protein and still the process of swelling around the eyes continues, then a doctor should be consulted. High blood pressure: Circulation and the kidneys are interdependent, the kidne

Kidney Disease Symptoms: You Can see other article based on information of Kidney you can read on website. Now we discuss about kidney Diseases symptoms kidney stones  If a person's kidneys start to deteriorate, some of the symptoms appear first but people ignore them and suffer serious damage. Let us tell you about five such symptoms and their treatment. Lower back pain: This is the first sign of kidney failure and if taken seriously it can prevent major damage. Sleeps on which side there is pain in the kidneys. After a short while this pain starts to occur on both sides, there is also difficulty in urinating. Itching, dry skin and redness on the skin: The most important function of the kidneys is to flush out waste products from the body through urine, but when they do not work properly and the urine does not come in properly, the toxins remain in the body and reddening our skin as well as the skin. It becomes dry and sometimes itchy. Changes in urinary ha
