The effects of the crude, methanol, hexane TLC and acetone extractable portion of strebulus as per on frog's heart and smooth muscle of rabbit were studied. The different extracts of S. asper showed a stimulant effect on frog's heart while the crude and methanol extracts showed not much alteration in the peristaltic activity of smooth muscle or rabbit. Methanol, hexane and acetone extractable p...

Extracts from several species of gram-positive cocci were prepared by a modification of the Rantz-Randall autoclave method and tested for reactions with rabbit anti-Peptostreptococcus anaerobius (ATCC 27337 and VPI 5737) sera in a capillary precipitin test. Antigen preparations from two reference strains of P. anaerobius (ATCC 27337 and VPI 5737) and six clinical isolates of P. anaerobius react...

Adequate biogeochemical characterization and monitoring of aquatic ecosystems, both for scientific purposes and for water management, pose high demands on spatial and temporal replication of chemical analyses. Near-infrared reflectance spectroscopy (NIRS) may offer a rapid, low-cost and reproducible alternative to standard analytical sample processing (digestion or extraction) and measuring tec...

We conducted an experiment to determine the effects of concentration and astringency of extractable and bound condensed tannins (CT) in tropical legumes on intake, digestibility, and nitrogen (N) utilization by sheep. The test legumes (Desmodium ovalifolium and Flemingia macrophylla) had similar concentrations of extractable CT (90 g/kg DM) but different concentrations of bound CT and astringen...

Phytoremediation is a promising approach for cleaning up soils contaminated with heavy metals. Information is needed to understand growth response and uptake mechanisms of heavy metals by some plant species with exceptional capability in absorbing and superaccumulating metals from soils. Greenhouse study, field trial, and old mined area survey were conducted to evaluate growth response and Cu p...

An algorithm substitution attack (ASA) can undermine the security of cryptographic primitives by subverting original implementation. ASA succeeds when it extracts secrets without being detected. To launch an on signature schemes, existing studies often needed to collect signatures with successive indices extract signing key. However, collection requires uninterrupted surveillance communication ...
