cml in breif cml is characterized by the proliferation of large numbers of immature wbc in the blood and bone marrow. in most of the patients , it is a clonal disorder in which all cell lines, express the philadelphia chromosome)q/22 translocation(it accounts for 20 of all leukemias and most cases occur over 25 yrs of age. the disease usually begins insidiously,but symptoms referable to anemia ...

در مقاله حاضر مبحث انتقال ماده همزمان با فعل و انفعال شیمیایی در مورد سیستمهای گاز-مایع با فرض آنکه واکنش در فاز مایع انجام شود مورد مطالعه قرار می گیرد معمولاً واکنشهای شیمیایی را که همراه با انتقال جرم صورت می گیرند با توجه به مکانیسم آنها به سه دسته کند ، سریع و آنی تقسیم می نمایند . در مورد واکنشهای کند می توان از تغییرات غلظت در حول سطح مشترک گاز –مایع صرفنظر نموده و در نتیجه غلظت ترکیب شون...
A salt metathesis reaction is a chemical process involving the exchange of bonds between two reacting chemical species, which results in the creation of products with similar or identical bonding affiliations. Hyperstructure theory is studied from the theoretical point of view and for its applications. In this paper, we provide some examples of hyperstructures associated with salt m...
in this study, an in-house multi-dimensional code has been developed which simulates the combustion of n-heptane in a homogeneous charge compression ignition (hcci) engine. it couples the flow field computations with detailed chemical kinetic scheme which involves the multi-reactions equations. a chemical kinetic scheme solver has been developed and coupled for solving the chemical reactions an...
