[1] The Radio Aurora Explorer CubeSat detected the first radar echoes during the solar storm of March 8, 2012. The 300 s ground-to-space bi-static radar experiment was conducted in conjunction with the Poker Flat Incoherent Scatter Radar in the local morning ( 8 am) over Poker Flat, Alaska. The geomagnetic conditions for the E region field-aligned irregularity generation were optimal due to str...

Three-dimensional transvaginal ultrasound was used to determine the location of early gestational sacs (E-GSs) and, as a result, the physiological implantation sites of human blastocysts. We examined 138 patients who were found by three-dimensional transvaginal ultrasound to have a GS with an inner diameter of 3 to 6 mm (E-GS). The uterine cavity was divided into three parts: upper, middle, and...

shiga toxin producing escherichia coli have been associated with hus, hc and ttp in human. we found recto-anal mucosal sample in sheep as well in cattle is the main site for e. coli o157 localization. 1246 e. coli isolates from 872 both healthy and diarrheic animals were analyzed, by screening for the presence of shiga toxin-producing (vt 1 and vt 2) and intimin (eae) genes used multiplex pcr. ...

INTRODUCTION The e-commerce revolution has affected all organizations. Of particular interest is its effect on small and medium-sized enterprises (SMEs), because we can observe an interesting duality, where these companies are most likely to benefit from the opportunities afforded by e-commerce (because through e-commerce, it is possible to level the playing field), and yet they appear to be sl...

background: we reviewed the monthly laboratory surveillance reports and hospital laboratory database in dhahira region, oman. methods: all patients for whom a stool sample examination request was made from 1 st january 2002 to 31 st december 2006 (5 years) were included in the study. antimicrobial resistance pattern was studied for 2 years period. the cultures were done using standard laborator...

Intestinal coccidiosis, caused by Eimeria species, is an economically-important disease of poultry production industry worldwide. This study was designed to investigate the prevalence of different Eimeria species in the farmed broilers of Khoy city, West Azarbaijan, North West Iran. A total of 26 broiler farms of different production capacities were arbitrarily selected and examined in 2013. In...

A bstract We use an abelian model to study linear power corrections which arise from infrared renormalons and affect event shapes in e + − annihilation into hadrons. While previous studies explored the two-jet region, this paper we focus on three-jet is most relevant one for determination of strong coupling constant. show that a broad class shape variables, can be written factorised form, invol...

The regulatory region of the trp operon of Citrobacter freundii was sequenced and compared with the corresponding regions of other enteric bacteria. Significant differences were noted in the promoter region. These differences are presumably responsible for the weak expression of the cloned trp operon in Escherichia coli. The presumed operator region, although nonfunctional in E. coli, has dyad ...
