Put a lamp in the lower part of the refrigerator. The thermostat is in there and controls the compressor. Cold air is diverted at a constant volume to the freezer so you must make the unit run based on refrigerator section temperature. If all works well, the lamp will both prevent the refrigerator section from freezing and keep the freezer cold.
Definition and purpose of peer review. Definition The peer review process is integral to scholarly research. It is a process of subjecting research methods and findings to the scrutiny of others who are experts in the same field. The process is considered essential, but has also been criticized as slow, ineffective and misunderstood.
What is a systematic review or meta-analysis? A systematic review answers a defined research question by collecting and summarising all empirical evidence that fits pre-specified eligibility criteria. A meta-analysis is the use of statistical methods to summarise the results of these studies. Systematic reviews, just like other research articles, can be of varying quality. 1  They are a significant piece of work (the Centre for Reviews and Dissemination at York estimates that a team will take 9-24 months), and to be useful to other researchers and practitioners they should have: 1  clearly stated objectives with pre-defined eligibility criteria for studies. 2  explicit, reproducible methodology.
