Рассматриваются исследования касающиеся оценки качества обмолота сои сорта Айма в обмолотном механизме зерноуборочного комбайна 30.40 Бизон. Процесс обмолота при разных рабочих параметрах молотилки регистрировали на кинопленке 16 мм с использованием специальной кинокамеры типа „Гиспид" рабтающей со скоростью передвижения ленты 500 клеток в секунду. Самое хорошее качество обмолота сои с влажностью семян 14% было получено при угловой скорости обмолотного барабана 73,5-78,5 рад/с, рабочей щели 25/15 мм и угловой скорости вала вентилятора 68- 73,3 рад/с.
The paper presents results of the studies dealing with evaluation of the quality of threshing of the Ajma soybean by the threshing complex of the Bizon combine harvester. The threshing process, provided various working parameters of the thresher, have been recorded on the 16 mm film using special "Hyspeed" camera operating with the speed of 500 frames per second. The best quality of threshing the soybeans (of the moisture of 14%) has been obtained at the rotational speed of the drum varying from 700 to 750 revolutions per minute, operating slot between the drum and the concave of 25/15 mm, and rotational speed of the fan in the range of 650-700 revolutions per minute.
The aim of the present study was to assess the possible correlation of p53 with CEA and Ca 19-9 serum levels as well as with selected clinicopathological data. 46 patients, who were gastrectomized due to gastric cancer between 1998 and 2001, were analyzed. The concentration of CEA and Ca 19.9 was estimated in serum. Mean percentage of p53-positive cells in present group was 33,69 %. The comparison of mean percentage of p53-positive cells with IHC reaction intensity revealed statistically significant, directly proportional correlation, with p<0,001. Mean CEA and Ca 19-9 serum concentration were 1,75± 1,71 ng/ml, and 17,34±44,73 U/ml respectively. No significant correlation between p53-expression, CEA and Cal9-9 was noted respecting several clinicopathological data of tumors. However clear trend of higher CEA and Cal9-9 values in groups of potentially worse prognosis (T3-T4; Nl-2; III grade of disease) was observed.
Ectopic pancreas, a rare entity, is defined as pancreatic tissue lying outside its normal location without anatomical or vascular connections with the pancreas proper. Most occurrences of heterotopic pancreas are located in the stomach wall, duodenum, small intestine or anywhere in the gastrointestinal tract. The aim of this study was to describe the endoscopic, endosonographic (EUS) and radiological features of these lesions. Management of the ectopic pancreas remains controversial. The authors describe 12 patients and try to recommend different kind of treatment in the light of the symptoms, location and size of the lesions.
