this study was conducted to evaluate some postmortem changes parameters (ph, color, rigor mortise and sensory evaluation) in kutum, captured by gillnet and beach seine. eight pieces of kutum were provided from each net and blood was sampled via 5 cc strile syringes from caudal vein and put into special tubes. then, fishes were placed into isolated boxes between thick layers of ice and transferr...
this study was intended to analyze the listening tapescripts of the elementary and pre-intermediate levels of total english textbooks from the pragmatic dimension of language functions and speech acts in order to see whether the listening tasks are pragmatically informative or not. for this purpose, 8 conversations from the two books were selected randomly, and then, the two pragmatic models of...
Discoloration of composite resins is considered to be a major factor in esthetic restoration failures. The aim of this study was to evaluate color stability of IDM composite (both light and self cure samples namely IL and IS), and to compare it with a self-cure composite (Degufill named DS) and a light cure ormocer composite (Definite, called DL in the Report). 60 disk shaped samples of each co...
according to coates’s (2004, as cited in zhang, 2010) definition of "conversational dominance" (p.111), it refers to the phenomenon of a speaker dominating others in interaction. specifically, it means how a speaker makes use of certain strategies to get the floor and maintain the floor. thus, the amount of talk is the main measurement for the dominance of the conversation. whether a speaker do...
after test and review results and analysis of farm data, the following results were obtained. the review examined farms was done and the results obtained in this study was to determine the effectiveness of vaccines hatchpak avinew (frozen) and hatchpak ib h120 with spray in broilers a day in factories incubation and at least,they can be as vaccines avinew and bioral h120 ability to create saf...
The aim of this study was to compare in vitro survival rates of in vivo and in vitro-produced bovine embryos by slow freezing or solid surface vitrification. In vivo-produced blastocysts (n = 210) and in vitroproduced blastocysts (n = 445) were randomly allocated in two cryopreservation groups. Group 1 embryos were exposed to 1.5 M ethylene glycol (EG) for 5 min, loaded in 0.5 ml straws, frozen...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
In order to study the bacterial flora of dead-in-shell ostrich chicks, twelve unhatched eggs which did nothave external pipping during the hatching period were transferred to the laboratory of microbiology. The eggshells were accurately disinfected and the embryos were removed and placed in a sterile plate. The surface of each embryo was swabbed with a sterile swab which was also plunged throug...
This study was designed to investigate the effect of vitrification and post-thaw survival and chromosomal aberrations caused by vitrification of vitrified 8-cell mouse embryos in comparison with a control group. To this purpose the survival rate and the frequency of chromosomal aberrations were assessed in frozen-thawed 8-cell mouse embryos after various storage durations in the presence of eth...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
