PERFORMANCE OF SCOTCH PINE RACES UNDER PRAIRIE CONDITIONS

Manual Performance under Cold Conditions

The purpose of this study was to investigate manual performance and thermal responses during low work intensity in persons wearing standard protective clothing in the petroleum industry when they were exposed to a range of temperatures (5, –5, –15 and –25°C) that are relevant to environmental conditions for petroleum industry personnel in northern regions. Twelve men participated in the study. ...

Performance of PV Topologies under Shaded Conditions

The test also determines a Shading Mitigation Factor (SMF) which represents the annual energy recovery of a power optimizer or microinverter system, compared to a traditional string inverter. The study found that the SolarEdge system recovered 28.3%, 21.9%, and 24.3% of energy lost by the string inverter system, with light, medium and heavy shading, respectively. These results indicate higher S...

Performance of Photovoltaics Under Actual Operating Conditions

Field Performance of Blue Pine (pinus Wallichiana) Seedlings Inoculated with Selected Species of Bio-inoculants under Nursery Conditions

A pot experiment was carried out during 2009 and 2010 to study the field performance of blue pine seedlings inoculated with selected species of bio-inoculants under nursery conditions .The experiment was laid in Completely Randomized Design with three replications which comprised of seven inoculants (Azotobacter sp., Azospirillum sp., Pseudomonas fluorescens, Bacillus subtilis, Pisolithus tinct...

pH electrode performance under automated management conditions

pH is frequently measured in laboratories, but to have confidence in the results it is necessary to know that it was measured properly. For an electrode to give accurate results it must be treated well and calibrated correctly. In this paper, an automated system for pH measurement is described; the system uses the operational pH scale and calibrates using two or three buffer solutions, taking p...
