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 ...
Resonance experiment was employed to investigate the mechanism of photoperiodic time measurement during initiation of ovarian growth and functions in the subtropical population of female tree sparrow (Passer montanus) at Shillong (Latitude 25 degrees 34 'N, Longitude 91 degrees 53 'E). Photosensitive birds were subjected to various resonance light dark cycles of different durations such as: 12-...
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
this experiment was carried out the aim of the effect of sainfoin forage and forage:concentrate ratios on feed intake, nitrogen balance,ruminal biohydrogenation and milk fatty acid profile in dairy ewes using of eight lori breed ewes according to a replicated 4 × 4 latin square design. treatments were adjusted from one to four according to forage:concentrate ratios of 35:65 with and without sai...
The aim of this study was to investigate the effect of different levels of soybean meal peptides on body weight gain, feed conversion ratio, feed intake intestinal morphology and microbial population in broiler chicks. In a completely randomized design 280 one-day-old Ross 308 male broiler chicks were allocated to 7 treatments with 4 replicates and 10 chicks per replicate. Broiler c...
Abstract Objective: The experiment was conducted to study the effects of selenium-enriched fermented Chinese herbal feed additive on growth performance, immune performance and meat quality fowl. Method: A total 180 Hyline brown chicks 7-day-old were randomly divided into 3 groups with replicates per group 20 replicate. These three control (basal diet), experimental I diet &Chinese additive)...
