hershfield method is commonly used for computing probable maximum precipitation (pmp) in most parts of the world for which the frequency factor (km) is considered to be 15 for computing 24-h pmp (pmp24). this value may not be suitable for different stations under different climatic conditions. in 1986 the world meteorological organization standardized the hershfield method and introduced the re...

background:the first step in diagnosis of diabetic nephropathy is measurement ofalbumin in a spot urine sample. the aim of this study was assessment of the accuracy of urinary albumin to creatinine ratio (uacr) in random urine specimens (rus) for microalbuminuria and macroalbuminuria screening in iranian diabetic patients. methods:a total of 200 diabetic patients participated to our study. 24 h...

Domains in macromolecular complexes are often considered structurally and functionally conserved while energetically coupled to each other. In the modular voltage-gated ion channels the central ion-conducting pore is surrounded by four voltage sensing domains (VSDs). Here, the energetic coupling is mediated by interactions between the S4-S5 linker, covalently linking the domains, and the proxim...

Gas-liquid chromatography was used to monitor the evolution of short chain fatty acids by Bacteroides fragilis in five media. Acetic and succinic acids, the prominent end products encountered, were readily detected within 24 h. Propionic, isobutyric, isovaleric, and lactic acids were usually recorded in more limited quantities. Maximum rates of bacterial multiplication, glucose catabolism, and ...
