سابقه و هدف: در کشور ایران از حدود 5/88 میلیارد مترمکعب آب استحصال‌شده منابع سطحی زیرزمینی، ۸۳ یعنی 5/93 درصد به بخش کشاورزی اختصاص می‌یابد، بزرگ‌ترین مصرف‌کننده است. مصرف رو افزایش معلول جمعیت، سطح زیر کشت تولیدات هست که به‌تبع آن سبب کاهش دسترسی افت ایستابی تخلیه آبخوان‌ها شده آمارها نشان می‌دهند این استراتژیک، تهدید کمیت کیفیت است ­طوری ­که هم ­اکنون تعداد زیادی دشت­ های شرایط بحرانی قرار دا...

spark plasma sintering (sps) method, as plasma activated sintering, is a method applicable for rapid sintering of metals and ceramics. owing to the advantage of rapid heating, the alumina ceramics obtained by sps have a grain size and density comparable to those of hot pressed ones. the increase of densification rate may be related to some difference in ion transport characteristics. this study...

case presentation the patient was a 65-year-old female with sps diagnosed 1 year before. assessments were performed, such as range of motion, muscle strength, pain, balance, and functional mobility. she had shoulder pain, with a score of 5/10 on the numerical pain rating scale for both shoulders. moreover, her muscle strength was impaired. although the patient could not maintain an upright posi...

Expansive laminoplasty for ossification of the posterior longitudinal ligament (OPLL) has had favorable outcomes. Many modifications of expansive laminoplasty have been developed, including expansive laminoplasty with and without spinous process spacers (SPS). The purpose of this study was to determine whether surgical outcomes were similar between expansive laminoplasty surgeries with and with...

We demonstrate superluminal light propagation using two frequency multiplexed pump beams to produce a gain doublet in a photorefractive crystal of Ce:BaTiO(3). The two gain lines are obtained by two-wave mixing between a probe field and two individual pump fields. The angular frequencies of the pumps are symmetrically tuned from the frequency of the probe. The frequency difference between the p...

It has recently been shown (Kunik et al., PLOS Comput Biol 2007;3(8):e167) that the occurrence of specific peptides (SPs) on sequences of enzymes allows for accurate EC classification of enzymes. We inquire whether these SPs play important roles in bringing about the enzymatic function. This is assessed by cross-checking the occurrence of SPs on enzymes with Swiss-Prot annotations and PDB spati...

Saw palmetto supplements (SPS) are commonly consumed by men with prostate cancer. We investigated whether SPS fatty acids and phytosterols concentrations determine their growth-inhibitory action in androgen-sensitive LNCaP cells and hamster flank organs. High long-chain fatty acids-low phytosterols (HLLP) SPS ≥ 750 nM with testosterone significantly increased and ≥500 nM with dihydrotestosteron...

This paper analyses the income and structural effects of the Single Payment Scheme (SPS). In particular, we analyze how the income distributional effects and farm restructuring are impacted by the SPS by accounting for entitlement tradability, cross-compliance and CAP 'greening' requirements, different SPS implementation models, and the entitlement stock. Our results suggest that the SPS implic...

Sucrose-phosphate synthase (SPS; E.C. 2.4.1.14) is the plant enzyme thought to play a major role in sucrose biosynthesis. In photosynthetic and nonphotosynthetic tissues, SPS is regulated by metabolites and by reversible protein phosphorylation. In leaves, phosphorylation modulates SPS activity in response to light/dark signals and end-product accumulation. SPS is phosphorylated on multiple ser...
