چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...
15 صفحه اولStandardized Calculation and Interpretation of Basic Cow Herd Performance Measures
Commercial cow-calf producers commonly use the term “percent calf crop,” but what does it mean? Does percent calf crop represent the number of calves born relative to the number of cows bred, or perhaps it is the number of calves born relative to the number of cows exposed to a bull? Some might calculate percent calf crop as the number of calves weaned compared to the number of calves born, or ...
متن کاملCullin the Beef Cow Herd
Removing select cattle from a herd (culling) is done to improve herd performance and profitability Production and market conditions influence culling criteria Some cattle are obvious candidates for culling (e g , cows with poor breeding performance or cancer eye), but cattle can and should be culled for reasons that may not be readily observable Simply put, cows are selected for culling based o...
متن کاملProfiting from the Cattle Cycle: Alternative Cow Herd Investment Strategies
Beef cow herd owners can benefit from incorporating price signals into their heifer retention decisions. Whereas a perfect forecast of calf prices over the productive life of the heifer added to the herd would be ideal, such information is not available. However, simple decision rules that incorporate current or recent prices and the knowledge that the cattle cycle likely will repeat itself can...
متن کاملIdentification of Factors Causing Heterogeneous Within-Herd Variance Components Using a Structural Model for Variances
Many applications of mixed linear statistical models for genetic evaluation of dairy cattle assume that genetic and residual components of variance are each constant across environments. However, this assumption is violated for production and conformation traits, which can reduce accuracy of selection and cause biases in the proportions of breeding animals chosen from each environment. Best lin...
