one of the goals of financial reporting is to provide the useful information in order to facilitate the decision making. accounting information system is of high importance for the users to make specific decisions. the information should be analyzed to present the valuable information to the investors so that in this paper, the relative content and return additive with cash recovery have been a...
application of most antibiotic growth promoters as feed additives has been banned in a lot of countries due to cross-resistance against pathogens and residues in tissues. therefore, scientists are searching for alternatives to antibiotics nowadays. medicinal plant extracts are one of the alternatives that have anti-microbial and growth promoting effect on poultry. in this paper, the benefits of...
the aim of the experiment was to determine the effect of different dry matter content and addition of silage inoculant on the ruminal protein degradability. alfalfa herbage was collected from two cuts and the fresh matter was sampled two times during each cut (with different dry matter content). during the preparation of experimental micro-silages, the chopped forage was treated with a microbia...
In order to study the inheritance of some traits related to grain yield in drought stress conditions in bread wheat (Triticum aestivum L.), F2, F3 and F4 generations derived from a Kharchia (tolerant) × Gaspard (susceptible) cross and their parents were used separately in a complete randomized block design with two replications. Stem length, biological yield, main spike straw weight, total spik...
staining behavior of an anti-graffiti polyurethane clear coating against accelerated weathering test
apermanent anti-graffiti clear polyurethane coating, using a silicone additive, was prepared and studied. various techniques, such as contact angle measurements and edx were employed to characterize and investigate thesurface properties of the coatings. the results revealed that with inclusion of silicon additive to clear coating, according to wu method, surface free energy was decreased from 4...
Six rice cultivars were crossed in half diallel design to evaluate their GCA and SCA in 2005. In the following year, parents and their progenies were grown in a randomized complete block design with three replications, and 10 traits were measured. The analysis of variance showed significant differences (p≤0.01) between cultivars. Furthermore, general combining ability (GCA) and specific combini...
a-Al2O3 is the most important raw material for synthesizing modern ceramics and high alumina refractories. Active Alumina (also known as Hydratable Alumina and r-Al2O3) is a kind of transition alumina which is produced by flash-calcining of Gibbsite at 500-600 oC. In this research, the effect of Ammonium bi-fluoride additive (NH4HF2), on the formation of a-Al2O3 from active alumina was investig...
for centuries, aloe vera has been used by many different cultures. the ancient greeks, the romans, the babylonians, indians and the chinese have all used aloe vera as a medicinal plant. one of the common experimental cancer models is sarcoma-180. when aloe was administered to mice bearing s-180 tumors, the tumor growth was inhibited. aloe vera is a dietary supplement and not a regulated drug. t...
A simulation study was conducted to address the issue of how purely additive (simple) genetic architecture might impact on the efficacy of parametric and non-parametric genomic prediction methods. For this purpose, we simulated a trait with narrow sense heritability h2= 0.3, with only additive genetic effects for 300 loci in order to compare the predictive ability of 14 more practically used ge...
Biochemical and physiological traits are affected by environmental stresses and therefore the breeding of these traits will play an effective role in stress tolerance. In this study, hybrids of five S7 lines of maize in a 5 × 5 half-diallel design were investigated in order to study the combining ability of biochemical and physiological traits of maize at the Research Farm of Graduate Universit...
