A critical step in the quantification of soil quality (SQ) is the selection of SQ benchmarks. The benchmarks used in this study were SQ ratings made by 32 farmer collaborators representing a range of farming systems, scales of operation and geographic locations in the Mid-Atlantic region of USA. Soils from 45 pairs of sites identified by their farmers as having good and poor SQ were sampled ove...

A novel fluorescent system has been assembled by using ATP, surfactant, and a squaraine dye in an aqueous buffer solution. In the system, a cationic surfactant such as cetyl trimethyl ammonium bromide (CTAB) forms a sphere-like micelle, whose positive charge at the surface of the micelle attracts the negatively charged ATP to form a unique organized nanostructure. Such an organized system is sh...

Two new 7-formamidocephalosporins have been isolated as their acetyl derivatives (SQ 28,516 and SQ 28,517) from fermentations of a Flavobacterium sp. SC 12,154. Structure 1 was deduced for SQ 28,516 from its spectroscopic properties while structure 2 was proposed for SQ 28,517. SQ 28,516 exhibits weak antibacterial activity.

A fast introduction to the the construction of the cohomology of sheaves pioneered by A. Grothendieck and J.L. Verdier. The approach is from the point of view of derived categories, though this concept is never mentioned. 1. Sheaves Let R commutative ring with 1. We denote by RMod the category of R-modules. For any topological space X we denote by OpenpXq the collection of open subsets. It can ...

BACKGROUND Poor sleep quality (SQ) is common after solid organ transplantation; however, very little is known about its natural history. We assessed the changes in SQ from pre- to 3 years post-transplant in adult heart, kidney, liver and lung recipients included in the prospective nation-wide Swiss Transplant Cohort Study. We explored associations with selected variables in patients suffering p...

BACKGROUND A hallmark of congestive heart failure (CHF) is the elevation of the cardiac natriuretic peptides (NPs), which have natriuretic, renin-inhibiting, vasodilating, and lusitropic properties. We have reported that chronic subcutaneous (SQ) administration of brain natriuretic peptide (BNP) in experimental CHF improves cardiorenal function. Vasopeptidase inhibitors (VPIs) are single molecu...

aim and background: in this study, the psychometric properties and hierarchal structural validity of short form health survey scale (sf-36) among students using structural equating modeling was investigated. methods and materials: a sample with 310 students (158 male and 152 female) from tehran university were chosen by multistage sampling method. for verifying discernment validity, two clinica...

background: quality of life (qol) is increasingly recognized as an important outcome measure in dermatology. psoriasis has a great impact on qol of patients, and has a strong effect on social relations, psychological status, and daily activities. this study describe and compare the impact of different grades of severity of psoriasis on qol of patients in north of iran. methods: this cross‑secti...
