the effect of traffic density on the accident externality from driving the case study of tehran
در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
15 صفحه اولTHE ISOLATION OF ENZYME TRANSKETOLASE FROM HUMAN ERYTHROCYTES: THE CHARACTERIZATION OF ITS QUARTERNARY STRUCTURE
Human erythrocyte transketolase (sedoheptulose-7-phosphate: D-glyceraldehyde-3-phosphate, glycolaldehyde transferase, E.C. 2.2.1.1.) has been isolated from erythrocytes with a specific activity of 59.84 U/mg. SDS-PAGE and SE-HPLC were used both as a measure of purity and as a preparative mean to obtain a higher degree of purity. Four protein bands corresponding to molecular weights of 32,0...
متن کاملPalmitoylation is not required for trafficking of human anion exchanger 1 to the cell surface.
AE1 (anion exchanger 1) is a glycoprotein found in the plasma membrane of erythrocytes, where it mediates the electroneutral exchange of chloride and bicarbonate, a process important in CO2 removal from tissues. It had been previously shown that human AE1 purified from erythrocytes is covalently modified at Cys-843 in the membrane domain with palmitic acid. In this study, the role of Cys-843 in...
متن کاملProtein 4.2 interaction with hereditary spherocytosis mutants of the cytoplasmic domain of human anion exchanger 1.
AE1 (anion exchanger 1) and protein 4.2 associate in a protein complex bridging the erythrocyte membrane and cytoskeleton; disruption of the complex results in unstable erythrocytes and HS (hereditary spherocytosis). Three HS mutations (E40K, G130R and P327R) in cdAE1 (the cytoplasmic domain of AE1) occur with deficiencies of protein 4.2. The interaction of wild-type AE1, AE1HS mutants, mdEA1 (...
متن کاملAlphavirus RNA replicase is located on the cytoplasmic surface of endosomes and lysosomes
Using morphological and cell biological techniques, we have shown that the RNA replicase of Semliki Forest and Sindbis virus (two closely related alphaviruses) is located in complex ribonucleoprotein structures associated with the cytoplasmic surface of modified secondary lysosomes and endosomes. These nucleoprotein complexes often form a bridge between the membrane of the endocytic vacuole and...
