propionic acid (pa) is a short chain fatty acid, a common food preservative and metabolic end product of enteric bacteria in the gut. the present study was undertaken to investigate the effect of pa on liver injury in male rats. male western albino rats were divided into two groups. the first group served as normal control, the second was treated with pa. the activities of serum hepatospecific ...

reluctance towards implementation of precision agriculture (pa) seems to be based on lackof consideration to education, extension, and research sectors. the objective of this study isto identify educational, extensional, and research requirements in application of the pasystem. the research population included all the experts in qazvin province who are familiarwith pa concepts and pa’s equipmen...

Aims. This paper reports on single-pulse radio observations of PSR B1702–19 and their implications for pulsar emission theories. Methods. These observations were made with the Westerbork Synthesis Radio Telescope at 1380 and 328 MHz. The PA-swing is used to constrain possible geometries of the pulsar and the single-pulse data is analysed for subpulse modulation correlations between the main pulse

Matchmaking is a complex process and requires tremendous expertise. Matchmakers in various industries often advertise proprietary technologies that would presumably help users find an ideal match in a shorter period of time. However, matchmakers might seek to deliberately reduce their matchmaking effectiveness because users would thus remain clients for a longer time and hence pay more fees. Th...

a new output structure for class e power amplifier (pa) is proposed in this paper. a series lc resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. this resonator causes low impedance at the second harmonic. the output circuit is designed to shape the switch voltage of the class e amplifier and lower the voltage stress of the transistor. t...

PA (Process algebra) is the name that has become common use to denote the algebra with a sequential and parallel operator (without communication), plus recursion. PA-processes are a superset of both Basic Parallel Processes (BPP) Chr93] and context-free processes (BPA). We study three problems for PA-processes: The reachability problem, the partial deadlock reachability problem (\Is it possible...
