This article presents the performance analysis of a conventional hybrid photovoltaic/thermal air heating collector. An excel spreadsheet is developed and various parameters are calculated for single-glass configuration. Results are presented to show the effect of various design and operational parameters on the performance of a system. These results are useful for designing such systems more scientifically.
Since the 1970s a lot of countries has concentrated their attention on photovoltaic panels. A lot of studies and research have been made. Many innovative systems and products have been put forward and their quality evaluated by academics and professionals. A range of theoretical models have been introduced and their appropriateness validated by experimental data. Important design parameters are identified...
Jet injectors may transmit blood-borne infections, such as hepatitis B virus (HBV) and human immunodeficiency virus (HIV). To evaluate the safety of an anticontaminant disposable device which protects the jet injector apparatus, 22714 healthy subjects were intradermally inoculated (38162 inoculations) with a variety of vaccines. All the subjects were systematically followed-up clinically and epidemiologically...
