the present research was conducted to accomplish two purposes. firstly, it aimed to explore and describe schematic structure or what halliday and hassan (1989, p.64) have called “generic structure potential” (gsp) of american english, iranian persian and iranian english newspaper editorials within systemic functional linguistics. secondly, a quantitative cross-comparison was made to investigate...

effects of lamb and parents coefficient of inbreeding (ci) on wool weight were studied using 10,868 wool records belonging to 3,244 iran black lambs (1,633 males and 1,611 females) representing 96 rams and 995 ewes collected during 1983-2006 from animal breeding station of abbas abad. year and month of shearing, ci of lamb and dam, sex and birth type had significant affect on wool weight among ...

The effects of inbreeding, heterosis, recombination loss, and percentage Holstein on the estimation of predicted transmitting abilities for fertility traits (calving interval, number of days from calving to first insemination, nonreturn rate, number of inseminations) and correlated traits (milk yield at test nearest d 110 and body condition score) were examined in a mixed population of Holstein...

in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...

Hemimelia as a congenital anomaly is a failure of development of extremities formation in embryonic period. This anomaly is defined as complete absence of the part of extremities and different forms were explained for hemimelia. Adactyly is an alternative name for transverse hemimelia and is a rare disorder in the most of animal species. A two months old male lamb with normal vital signs was re...

The number of lambs sold per ewe mated in the breeding flock has a considerable impact on sheep operation profitability. This depends primarily on fertility, prolificacy (# of lambs), and lamb survival, mothering ability, milk production of the ewe and lamb growth rate. Optimal reproduction does vary by environment and management system – some sheep operations don’t want a lambing rate over 200...

All camelids (including the Bactrian [2 humps] and Dromedary [1 hump] old world camels) have a diploid number of 74 chromosomes. Interbreeding can occur between any of these species, producing fertile offspring. In llama and alpaca are occasionally interbred, producing an animal with longer but coarser fibre length than Alpaca. These are known as Huarizo. Using artificial insemination between o...

in this study reference as one of the five cohesive devices in the achievement of textuality in english and persian narrative/descripitive written texts is focused on and analysed . to do so , the theoretical framework elaborated by halliday and hasan (1976) and its version adapted by the writer to match the sub-types of reference in farsi are applied to the analysis of reference in english and...

BACKGROUND Echocardiography is a cost-efficient method to screen cats for presence of heart disease. Current reference intervals for feline cardiac dimensions do not account for body weight (BW). OBJECTIVE To study the effect of BW on heart rate (HR), aortic (Ao), left atrial (LA) and ventricular (LV) linear dimensions in cats, and to calculate 95% prediction intervals for these variables in ...
