monumental changes occurring on a daily basis have altered the world into a global village of expanding technology and shrinking geography in which preparing language learners for intercultural communication seems to be a sine qua non for modern language education. employing a cross-sectional design in its first phase, this study investigated the intercultural sensitivity and language proficien...
This experiment was carried out to study the effect of different levels (3.06, 3.23, 3.4, 3.57 and 3.74%) of calcium and vitamin D3 (2000, 2200 and 2400 IU/kg diet) on eggshell quality of laying hens. In a completely randomized design and in a 5×3 (15 treatments) factorial arrangement, two hundred and forty (240) white leghorn laying hens, strain Hy-Line W36 and 26 weeks old, were divided into ...
The most important step in developing of a sugar beet hybrid for target trait is selection of CMS line or single cross. In the present study, 12 progenies derived of 4 sugar beet lines(as female parent) with different level of rhizomania resistant, along with 3 pollinators 27270, 27273 and 27274(as male parent) and parents were evaluated in two locations (Mashhad and Shiraz) with rhizomania inf...
the present study was an attempt to determine the types of motivation and levels of foreign language learning anxiety among efl students studying at azad and state universities in kermanshah and to determine the relationship between these two factors and language proficiency and gender. to this end, the foreign language learning motivation scale, by deci and ryan )1985(, were administered to 12...
s of papers 91 yolk (YP), Haugh units (HU), yolk index (YI), shell percent (SP), shell thickness (ST) and egg specific gravity (ESG). The vitamin D influenced the parameters HU, YI, SP, ST, ESG when in thermoneutral temperature, the YI in a cycling heat stress and ST, ESG in constant heat stress. The vitamin C interfered on HU, SP, ST, ESG under thermoneutral temperature and on YI under cycling...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Hatchability is a very important trait in a breeding program which has a great economical impact on franchise hatcheries. The variability between and within strains raises the question whether reproductive performance can be improved by selection within lines. The aim of this study is to analyse the genetic background of the hatchability and its correlations between egg quality and production t...
An experiment was carried out using 200 hundred Athulya birds divided into 10 treatments (T1-T10) to find out the effect of phytase enzyme on egg quality traits supplemented at 0, 500 and 1000 units/kg in low energy, low protein and low energyprotein layer chicken diets containing available phosphorus of 0.30 per cent from 21 to 40 weeks of age. A standard layer ration was offered to birds in T...
to investigate the genetic diversity of persian walnut (juglans regia), 608 different walnut genotypes of neyriz region were evaluated for 30 morphological characteristics including kernel color, fruit shape, shell seal, shell texture and kernel plumpness, kernel weight, percentage of kernel as well as thickness of shell. the correlation between was traits in most cases significant at either 1 ...
