Numerous studies throughout North America allege deleterious associations among invasive Asian Carp and native fishes; however, no empirical evidence on a system-wide scale exists. We used Mississippi River Basin fish community data collected by the Long Term Resource Monitoring program and the Missouri Department of Conservation to evaluate possible interaction between Asian Carp and native fi...
The mechanism for the potentiation of the actin-activated ATPase of smooth muscle myosin by tropomyosin is investigated using smooth muscle actin, tropomyosin, and heavy meromyosin. In the presence of tropomyosin, an increase in Vmax occurs with no effect on KATPase and Kbinding at 20 mM ionic strength. Utilizing N-ethylmaleimide-treated subfragment-1, which forms rigor complexes with actin in ...
The objective of this study was to determine the influence of Ca source [highly soluble calcified seaweed (HSC) or limestone], phytase supplementation, and dietary levels of Ca on bird performance and mineral digestibility (Ca and P) during a necrotic enteritis (NE) episode. Cobb 500 male broilers were weighed and randomized into 8 treatment groups (9 pens/treatment; 30 birds/pen) at day of hat...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی بیان شده اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...
