E-retailing refers to sale goods and services on the Web. E-retailing operation can be a simple reaffirmation of the desire and the opportunity to buy some goods or service using credit card and following transfer the required amount from one account to another. But it also can be very complex when, for example, to perform a transmission of information it should be carried out through the many networks.

The first examples of e-retailing have roots in banking and the process is known as “wire transfers.” In this process, the buyer authorized his Bank to make a wire transfer to an account in another bank. This process included the transfer of money across the country or to the other side of the world and is usually made by large enterprises and other independent commercial organizations. To replace the wire transfers, there were electronic means of transmitting financial information. After doing this, the banks to notified each other about transfer by telegrams, telex or email.

Psoriasis is a chronic, non-infectious disease, a dermatosis, which affects mainly the skin. It is now assumed to have autoimmune nature. Psoriasis is usually manifested by appearance of extremely dry red lumps, raised above the surface of the skin, the so-called papules, which merge among themselves, forming plaque. These papules are sites of chronic inflammation and abnormal proliferation of lymphocytes, macrophages, and keratinocytes of the skin, as well as excessive angiogenesis (formation of new small capillaries) in the underlying layer of the skin.

Psoriasis is a chronic disease characterized by alternating periods of spontaneous or induced by some or other therapeutic effects remission and periods of spontaneous or induced by some adverse external influences (alcohol, intercurrent infections, and stress) recurrences or exacerbations. The severity of the disease may vary in different patients and even in the same patient during periods of remission and exacerbation in a very wide range, from small local lesions to the patient’s body fully covered with psoriatic plaques.

Magnetic refrigeration is a method of obtaining a temperature lower than 0.7 K. To obtain low temperatures typically liquefied gas is used. Lowering the pressure over the free surface of the liquid, you can get the temperature below the normal boiling point of the liquid. For example, the flow of nitrogen vapors can reduce temperature to the temperature of the triple point of nitrogen (63 K), by pumping hydrogen vapors (above the solid phase) you can achieve the temperature of 10 K, by helium vapor pumping (with very good conditions of the experiment) you can achieve the temperature of about 0.7 K.

In 1926, the William Francis Giauque and Peter Debye independently showed that at very low temperatures paramagnetic substances should have a great value of magnetocaloric effect and that this effect can be used to obtain low temperatures. In their first experiments in 1933, Giauque and McDougall manage to obtain the temperature of 0.25 K by demagnetizing gadolinium salts.
The method is based on the effect of heat from the paramagnetic salts at magnetizing and subsequent absorption of heat by degaussing. This allows you to get the temperature down to 0.001 K. Continue reading “Magnetic Refrigeration Research Paper”

Stress is a state of the individual in extreme conditions, manifested at the physiological, psychological, and behavioral levels. It is a reaction of the organism to external stressors. Some of the stressors cause stress among students. Among them, there are school tests, admission to a higher education institution, the beginning of a new life, a new relationship with other students and many others. While studying in high school, students not only get some knowledge, but also are actively engaged in social activities. However, there in not always time to have to handle the incoming problems one at the time, so students have to deal several tasks simultaneously, which also causes stress.

It is known that most of the students are making a major effort in preparing for exams. During the examination session, the students do go tired and even may develop depression. The empirical study, using a test of academic stress, designed by J. Rough, was conducted among the students fourth year studying comparative philology. The testing took place in the middle of semester. Such factors as the academic load, strict teachers, unwillingness to study, lack of textbooks, conflicts among the students, and shared accommodation were less than expected.
