In 2004, 3 and 4 strains of avian influenza virus (subtype H5N1) were isolated from waterfowl and chickens, respectively, in central People's Republic of China. Viral replication and pathogenicity were evaluated in chickens, quails, pigeons, and mice. We analyzed the sequences of the hemagglutinin and neuraminidase genes of the isolates and found broad diversity among them.
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
Background: Achieving quality care is an important issue which is often paied attention to in providing nursing care. It seems that communication skills can affect the quality of care. Aim: This study investigated the effect of training the communication skills on the quality of nursing care in patients. Methods: The study was a pretest/posttest experimental design with control group. 60 nurses...

Infectious bursal disease virus (IBDV) causes an economically significant disease of chickens worldwide. The emergence of very virulent IBDV (vvIBDV) has brought more challenges for effective prevention of this disease. The molecular basis for the virulence of vvIBDV is not fully understood. In this study, 20 IBDV strains were analysed phylogenically and clustered in three branches based on the...
Salmonella and Campylobacter continue to be major foodborne pathogens and raw poultry is considered to be an important source of these bacteria. In this study, the prevalence and numbers of Salmonella and Campylobacter spp. in relation to isolation/sampling methods were determined in 241 whole raw chickens purchased from retail outlets in England during the winters of 1998/1999 (101 chickens) a...
The study was conducted to characterize the indigenous chicken ecotypes and identify production system of owners across different locations. three districts West Hararghe zone Oromia region, Gamachis, Tullo Ciro district were purposely selected represent high-altitude, mid-altitude low-altitude agro-ecologies, respectively. Three kebeles from locations (urban, peri-urban rural) in each that mak...
The main reason preventing broiler chickens from reaching their genetic potential and hurting performance in the tropics is heat stress. This study aimed to ascertain how Justicia carnea leaf powder (JLP) supplementation affects chickens’ performance, blood indices, antioxidant status, gut microflora tropical environments. A completely randomized method was used assign 240 Cobb 500 chicks exper...
the ability to speak two languages in the world is a remarkable achievement. there is a good reason to believe that bilingualism is the norm for the majority of people in the world because 70% of the earth’s population are supposed to be bilingual or multilingual. various investigations have shown that the native language impacts foreign word recognition, and this influence is adapted by the de...
