در تحقیق حاضر، ?-آمیلاز حاصل از باسیلوس سابتیلیس بر روی سطح سیلیکاژل، از طریق برقراری پیوند کووالانسی تثبیت شد و سپس اثر میدان مغناطیسی ایستا (mt13) برتثبیت و فعالیت ?-آمیلاز (تثبیت شده و آزاد) در دمای c°25 و phهای مختلف (0/6، 5/6، 9/6و 6/7) مورد بررسی قرار گرفت. ?-آمیلاز (آنزیم آزاد( و واکنش آنزیم-سوبسترا (آنزیم آزاد و تثبیت شده) به ترتیب برای مدت 100 دقیقه و 5/1 دقیقه در دمای c°25 در معرض مید...
The aim of study was to assess the metabolic syndrome in preeclampsia women. The study was performed on 50 women. The metabolic syndrome prevalence was 66%. Serum glucose, triglyceride and LDL-cholesterol levels significantly were increased and HDL- cholesterol level significantly was decreased in metabolic syndrome patients. These patients showed high prevalence of components of the syndrome. ...
BACKGROUND Anencephaly is a neural tube defect incompatible with life. The aim of this prospective study was to determine the prevalence of anencephaly in Gorgan, northern Iran. METHODS During 1998 - 2005, 49,534 newborns at Dezyani hospital in Gorgan were screened for neural tube defects. Clinical and demographic data of the diagnosed cases were recorded in a pre-designed questionnaire for a...

The dust event from 12 January to 17 2021 (“1.12 event”) is the first process in and earliest last two decades. 14 18 March (“3.15 was strongest storm past decade. Distribution, transport, impact on urban air quality of these typical events were studied using multi-source satellite data, a HYSPLIT trajectory model, 3D concentration-weighted model. Results show that both affected wide range area...
The Deep Thunder mesoscale weather modelling and visualization system has been run semi-operationally since January 2001 at the IBM Thomas J. Watson Research in Yorktown Heights, NY focusing on the New York City metropolitan area. The model used in this work is derived from earlier work supporting the 1996 Centennial Olympic Games in Atlanta (Snook et al, 1998). This is a highly modified versio...

The purpose of this research is to analyze anemometer data to study the wind regime in Kashan and to investigate the role of different land uses in sand storms. Therefore, anemometer data obtained from synoptic station of Kashan were analyzed during a 40-year period (1966-2005) using different methods. Seasonal and annual wind roses and storm roses for different lands were created using WRPlot ...
Human risk of infection with Borrelia burgdorferi, the Lyme disease agent, in eastern United States.
The geographic pattern of human risk for infection with Borrelia burgdorferi sensu stricto, the tick-borne pathogen that causes Lyme disease, was mapped for the eastern United States. The map is based on standardized field sampling in 304 sites of the density of Ixodes scapularis host-seeking nymphs infected with B. burgdorferi, which is closely associated with human infection risk. Risk factor...
The variations of visibility, PM-mass concentration and mixing-layer height (MLH) in four major urban/industry regions (Shenyang, Anshan, Benxi and Fushun) of central Liaoning in Northeast China are evaluated from 2009 to 2012 to characterize their dynamic effect on air pollution. The annual mean visibilities are about 13.7 ± 7.8, 13.5 ± 6.5, 12.8 ± 6.1 and 11.5 ± 6.8 km in Shenyang, Anshan, Be...
