Purpose To investigate the feasibility of texture analysis apparent diffusion coefficient (ADC) maps for differentiating fat-poor angiomyolipomas (fpAMLs) from non-clear-cell renal cell carcinomas (non-ccRCCs). Methods In this bi-institutional study, we included two consecutive cohorts different institutions with pathologically confirmed solid masses: 67 patients (fpAML = 46; non-ccRCC 21) mode...
simulating discharge and sediment production using swat in chehelchai watershed of golestan province
runoff and sediment measurement is difficult in mountain watershed because of many different problems such as time and financial limitations. so using simulation model is necessary in this regard. accuracy and precision evaluation of models for different watershed of iran is necessary. the aim of this study was the evaluation of swat model efficiency in simulation of runoff and sediment yield i...
The IL-1β play a major role in inflammatory disorders and IL-1β production inhibitors can be used in the treatment of inflammatory and related diseases. In this study, quantitative relationships between the structures of 46 pyridazine derivatives (inhibitors of IL-1β production) and their activities were investigated by Multiple Linear Regression (MLR) technique Stepwise Regression Method (ES-S...
Iron poisoning has become uncommon. This success may underscore the importance of prevention by interventions gleaned from poison center data and poison prevention advocacy. Blister packaging, smaller dosages, and education of parents and health care professionals have led to a great decline in iron poisoning in the past two decades. Unfortunately, however, significant iron poisonings still occ...
Simulation of water and solute transport in soil is very useful for optimum management of water and fertilizer use. In this study, the HYDRUS-1D model was used to simulate water and nitrate transport in furrow irrigation of sugarcane. For this putpose, a large-scale experiment was performed as a split plot design based on the randomized complete blocks with 3 replications in a 25-hectare piece ...
در پژوهش حاضر، روی استانات (zn2sno4) با مورفولوژی های مکعبی و گلی به ترتیب با روش های همرسوبی و هیدروترمال سنتز و خواص فتوکاتالیزوری آن ها در حذف ماده رنگزای آلی (قرمز بازی 46) مطالعه شد. خواص ساختاری فتوکاتالیزورهای سنتز شده توسط الگوی پراش اشعه ایکس (xrd)، طیف مادون قرمز (ft-ir)، طیف بازتابش پخشی (drs) و تصاویر میکروسکوپ الکترونی روبشی (sem) مورد بررسی قرار گرفت. در بخش اول کار پژوهشی، روی ا...
introduction: complications of caustic ingestion swallowing in children of singe to gullet severe stricture and andoscopic actions and multiple surgeries is different that increase the risk of gastrointestinal perforation and gastrointestinal malignancies ..... because acid substances have bad taste and these are tissue coalescence in location of contact thus attribute alkali make lose of inj...
