 Methanotrophs in soil serves as a major atmospheric methane sink, and soil management has a direct impact on the diversity of microorganisms in soil. This study was set to identify methanotrophs in soil under different management systems. The study was conducted at the Ohio Agricultural Research and Development Center (OARDC), Ohio State University (OSU), Wooster, Ohio, US as part of their long continuous research in No-Till production.

     This  study was aimed to investigate the  association  between thyroid  disorders and  Helicobacter  pylori  infection  in 122  patients (100  females  and  22  males ) referred to the  Specialized Center  for  Endocrinology  and  Diabetes at  Al –kindy  Hospital  in  Baghdad . For comparison, 60 healthy  individuals (31 females and 29 males),who  had  no  thyroid  disorders, were  also  included   in   the  study. Blood samples were  collected  from  both  patients and the  healthy  individuals.

      Two hundred and six clinical specimens were collected from four different hospitals in Baghdad during the period (February to October 2010) ; these specimens included swabs from anterior nares, hands and ear swabs that were collected from visitors, hospitalized patients and the health care workers in these hospitals. Diagnostic results show that 154 out of the 206 specimens gave positive

The effect of static magnetic field on the growth and biochemical indices of five fungal species were studied (Aspergillus niger, Alternaria alternate, Fusarium oxysporum, Penicillium chrysogenium and Rhizopus oryzae). Exposing the above species to the northern pole, southern pole and both poles and their influences were compared with the control treatment (without magnetic field energy).
