When searching for an article on the topic, I'm sure you've seen both: a systematic review and a literature review. They do seem similar, but do they stand strong as the same? The short answer is no. But to conclude, we will walk through the history and intent while highlighting key factors that separate them. As this article is written within the context of higher education, it will refer specifically to literature and systematic reviews. However, these concepts are applicable outside of academia as well.

Having complaints and grievances with other employees is natural in a company. Many co-workers report those complaints to the higher authorities. They report them in the form of a letter called a 'grievance letter'. The problem is that many workers in a company do not know about writing a grievance letter. They just want to make the complaint without properly mentioning the problem and evidence. Keeping this in view, today's article is going to discuss the top things you must take care of when writing a grievance letter. There will also be a sample letter at the end of the article with top things. Thus, keep reading it until the end.

Funding is the major obstacle for students aspiring to enrol in a PhD degree programme in international universities. Reputed universities are expensive, and as an international student, it is costly to study in an international university. Many students find it impossible to achieve their dream of doing PhD from a reputed university. The UK is the most expensive country to go to for a PhD programme without any question. Britain is one of the most developed countries to live in, and it is the best place to study. Many students dream of going to the United Kingdom for higher education because of its state of the art universities, premium faculty, and multiple job opportunities.

Relying on the low operating temperature of the air end, CMN has developed a unique screw hydrogen compressor with a flow range of 5 to 59m3/min and a pressure range of 4 to 45bar. Since water is directly injected into the air end for compression, the operating temperature of the host will usually not be higher than 45 degrees Celsius, so safety can be guaranteed.

The characteristics determined by the partial pressure of water vapor in compressed air and the temperature of compressed air are used for cooling, dehydration and drying. While keeping the compressed air pressure basically unchanged, lowering the temperature of the compressed air can reduce the water content in the compressed air, and the excess water vapor will condense into liquid. The refrigerated dryer uses this principle to dry compressed air using refrigeration technology, so the refrigerated dryer has a refrigeration system. Refrigerated air dryer working Refrigerated air dryer how it works The refrigerated dryer sucks the low-pressure (low-temperature) refrigerant in the evaporator into the compressor cylinder. After the refrigerant vapor is compressed, the pressure and temperature increase at the same time; the high-pressure and high-temperature refrigerant vapor is pressed to the condenser. The higher temperature refrigerant steam exchanges heat with the lower temperature cooling water or air. The heat of the refrigerant is taken away by water or air and condensed, and the refrigerant vapor becomes a liquid.
