اطلاع از وضعیت حدود رطوبتی ظرفیت زراعی و نقطه پژمردگی دایم،‍ در برنامه ریزی های آبیاری و مدیریت زراعی بسیار مهم است. تعیین دقیق این حدود با استفاده از دستگاه صفحه فشاری صورت می گیرد، لیکن این کار معمولاً وقت گیر بوده، و در عین حال امکانات مورد نیاز آن در همه آزمایشگاه ها یافت نمی شود. بنابراین، با تخمین این حدود از روی برخی ویژگی های فیزیکی و شیمیایی خاک، می توان اطلاعات مفیدی از توانایی نگهداری...

BACKGROUND The UK population is ageing; improved understanding of risk factors for hospital admission is required. Linkage of the Hertfordshire Cohort Study (HCS) with Hospital Episode Statistics (HES) data has created a multiple-failure survival dataset detailing the characteristics of 2,997 individuals at baseline (1998-2004, average age 66 years) and their hospital admissions (regarded as 'f...

Soil water characteristic curve (SWCC) is one of the most essential hydraulic properties that play fundamental role in various environmental issues and management. SWCC gives important information for movement, soil behavior, infiltration, drainage mechanism, affecting circle aquifer recharge. Since world’s freshwater withdrawals go irrigation uses, decoding beneficial, as it affects saving thr...

Field capacity (FC) and permanent wilting point (PWP) are important factors affecting irrigation scheduling and field management. FC and PWP can be estimated from some of the soil physical and chemical properties. Pressure Plate apparatus is usually used for determination of FC and PWP, but this is a time-consuming and laborious procedure besides, the apparatus may not be available in many labo...

SUMMARY Phylogenetic Web Profiler (PWP) is a web-based service designed to perform phylogenetic profiling of proteins against genomes. The current version offers a selection of 63 completed genomes and available plasmids as annotated in the PEDANT genome database. Unlike currently available applications, this tool offers several choices of ortholog prediction parameters including E-value cutoff...

Laan in (Ph.D Thesis, Tartu. 1999) introduced the principal weak form of Condition $(P)$ as Condition $(PWP)$ and gave some characterization of monoids by this condition of their acts. In this paper first we introduce Condition (G-PWP), a generalization of Condition $(PWP)$ of acts over monoids and then will give a characterization of monoids when all right acts satisfy this condition. We also ...

In this paper first of all we introduce Property $U$-($G$-$PWP$) of acts, which is an extension of Condition $(G$-$PWP)$ and give some general properties. Then we give a characterization of monoids when this property of acts implies some others. Also we show that the strong (faithfulness, $P$-cyclicity) and ($P$-)regularity of acts imply the property $U$-($G$-$PWP$). Finally, we give a necessar...
