In th. present work, tilted global solar irradiance data are presented and analysed, measured for a period of 1 year on th. campus of Bah.ain Polytech.ic, Kingdom of Bah.ain, from both.a fixed ph.tovoltaic panel and a moving one via a two-axis solar tracker. Th. fixed panel faces south.with.an angle of 26 degrees with.respect to th. h.rizontal, coinciding with.th. local geograph.cal latitude. Th. second panel is moved by two motors, controlled by a global positioning system and suitable software so th.t th. Sun's rays are perpendicular to th. panel surface. A pyranometer is installed on each.panel, recording th. tilted global solar irradiance, stored by using a data logger. Th. analysis of th. data obtained sh.ws a 33% solar energy gain on an annual basis for th. moving panel (2780 versus 2088 kWh.m2 on th. fixed panel). More importantly, in June, wh.n th. energy demand in Bah.ain is elevated due to th. increased residential cooling loads, th. solar energy received by th. moving panel is 54.7% h.gh.r compared with.th.t of th. fixed panel. On a percentage basis, th. increase in solar energy from th. moving panel is profound in th. early morning and late evening h.urs. Moreover, th. reduction in th. solar energy received by th. fixed panel from May to June does not appear in th. moving panel because of th. adjustable orientation of th. latter. Th.ough.ut th. year, th. mean daily solar power varies between 0.37 and 0.56 kW/m2 for th. fixed panel, and 0.45 and 0.70 kW/m2 for th. moving panel. In winter, solar energy fluctuations are elevated due to erratic weath.r conditions th.t present a peak standard deviation of 28% of th. corresponding mean. Th. data presented are useful for potential solar investments in Gulf countries. Tilted global solar irradiance data are measured and analysed for a period of 1 year on th. campus of Bah.ain Polytech.ic, Kingdom of Bah.ain, from both.a fixed ph.tovoltaic panel and a moving one via a two-axis solar tracker.

Th.s review explores th. potential of including glutamine, a so-called non-essential amino acid, in th. formulation of reduced-crude protein (CP) diets for broiler ch.ckens. Th.re is a precedent for benefits wh.n including glycine and serine in reduced-CP diets. Fundamentally th.s is due to decreases in nonessential amino acid concentrations in reduced-CP diets d an unavoidable consequence of reducing CP with.ut amino acid supplementation. Th. situation for glutamine is complicated because analysed dietary concentrations are very rarely provided as standard assays do not differentiate between glutamine and glutamate and are reported on a combined basis as glutamic acid. Th. dietary requirement for glutamic acid is approximately 36.3 g/kg but it is increasingly unlikely th.t th.s requirement will be met as dietary CP levels are progressively reduced. Glutamine is an abundant and versatile amino acid and constitutes 50.5 mg/g of wh.le-body ch.cken protein and is th. dominant free amino acid in systemic plasma wh.re it h.s been sh.wn to provide 22.6% (139.9 of 620.3 mg/mL) of th. total in birds offered 215 g/kg CP, wh.at-based diets. In addition to dietary intakes, glutamine biosynth.sis is derived mainly from th. condensation of glutamate and ammonia (Nh.) catalysed by glutamine synth.tase, a reaction th.t is pivotal to Nh. detoxification. Glutamate and Nh. are converted to glutamine by ph.sph.tedependent glutaminase in th. reciprocal reaction; th.s, glutamine and glutamate are interch.ngeable amino acids. h.wever, th. rate of glutamine biosynth.sis may not be adequate in rapidly growing broiler ch.ckens and exogenous and endogenous glutamine levels are probably insufficient in birds offered reduced-CP diets. Th. many functional roles of glutamine, including Nh. detoxification and maintenance of acid-base h.meostasis, th.n become relevant. Twenty feeding studies were identified wh.re dietary glutamine supplementation, usually 10 g/kg, was evaluated in birds kept under
