asymptotic property of order statistics and sample quntile
چکیده: فرض کنید که تابعی از اپسیلون یک مجموع نامتناهی از احتمالات موزون مربوط به مجموع های جزئی براساس یک دنباله از متغیرهای تصادفی مستقل و همتوزیع باشد، و همچنین فرض کنید توابعی مانند g و h وجود دارند که هرگاه امید ریاضی توان دوم x متناهی و امیدریاضی x صفر باشد، در این صورت می توان حد حاصلضرب این توابع را بصورت تابعی از امید ریاضی توان دوم x نوشت. حالت عکس نیز برقرار است. همچنین ما با استفاده...
15 صفحه اولBronchial challenge tests: usefulness, availability and limitations
Indirect challenges to assess bronchial hyperresponsiveness are being increasingly used both for research and for assessment in the routine pulmonary function laboratory. ‘‘Indirect challenges act by causing the release of endogenous mediators that cause the airway smooth muscle to contract with or without inducing microvascular leakage. Because the responses to these challenges are modified or...
متن کاملPhosphorus Availability from Swine and Dairy Slurries
Compared to nitrogen (N), relatively little is known about the availability of phosphorus (P) from manure to crops. Many state extension bulletins recommend that 50-80% of total P in manure is available to crops the first year after application. This number is likely based on the fact that 35-90% of P in manures is in the inorganic form (Peperzak, et al., 1959; Barnett, 1994), which is immediat...
متن کاملAssessing protein availability of different bioethanol coproducts in dairy cattle.
Bioethanol production has led to the production of considerable quantities of different coproducts. Variation in nutrient profiles as well as nutrient availability among these coproducts may lead to an imbalance in the formulation of diets. The objectives of this study were to fractionate protein and carbohydrates by an in situ approach, to determine ruminal availability of nutrients for microb...
متن کاملeffects of alfalfa maturity and cutting times on availability of alfalfa hay protein for dairy cows
this experiment was conducted to consider the effects of maturity and cutting time on chemical composition and available protein content of alfalfa hay for dairy cows.. alfalfa hay harvested at two maturity stages (pre-bloom and early bloom) and two cutting times (morning and afternoon). available protein was predicted using nrc (2001) and dve/oeb (1994) models. in the nrc model (2001), alfalfa...
