The process of migmatitization in the Ghareh Naz has resulted in the formation of various rate of partial melting and eventually the formation of a large spectrum of metatexite and diatexite migmatites. Mineral chemistry studies by EPMA method shows that amphibole composition is magnesio-hastingsite and has a metamorphic origin and feldspar composition is andesine to oligoclase. Effective react...
in this paper, the ritz-galerkin method in bernstein polynomial basis is applied for solving the nonlinear problem of the magnetohydrodynamic (mhd) flow of third grade fluid between the two plates. the properties of the bernstein polynomials together with the ritz-galerkin method are used to reduce the solution of the mhd couette flow of non-newtonian fluid in a porous medium to the solution o...
CONTEXT Cyst fluid CEA concentration>192 ng/mL has proven accurate to differentiate mucinous from non-mucinous pancreatic cystic neoplasms. It is unclear whether the degree of cyst fluid CEA elevation is predictive of malignant behavior in IPMNs. OBJECTIVES To determine whether elevated cyst fluid CEA concentrations were predictive of invasive cancer. DESIGN Cross sectional study. SETTING...
In a 4-year longitudinal study, the authors investigated effects of retention in first grade on children's externalizing and internalizing behaviors; social acceptance; and behavioral, cognitive, and affective engagement. From a large multiethnic sample (n = 784) of children below the median on literacy at school entrance, 124 retained children were matched with 251 promoted children on the bas...
مقایسه کانسارCu-Ag-Au قلعه زری با دیگر کانسارهای نوع Iron Oxides Cu-Au (IOCG) و ارائه ردهبندی جدید
The Qaleh-Zari specularite- rich Cu-Au-Ag deposit is located 180 Km south of Birjand. Host rocks are mainly Tertiary andesites and andesitic basalts and some Jurassic shales and sandstones. Andesitic rocks from the western region of Qaleh-Zari were dated to 40.5±2 Ma. Four trends of faults and joints are identified in the mine area. The oldest is mineralized. Three major sub-parallel quartz ve...
مقدمه: فرکتالها عبارتند از ساختارهای هندسی پیچیده. علم فرکتال که به بررسی این ساختارها می پردازد در سال 1975 ابداع گردید و امروزه نه تنها در علوم مهندسی بلکه در علوم پزشکی نیز جایگاه ویژه ای یافته است. فرکتال ها در تشخیص بیماری های استخوانی و مدل سازی ساختار استخوانها و تحلیل تغییرات ساختار آنها و تحلیل ریتم و ضربان قلب و تشخیص بیماری های قلبی کاربرد دارند. هرچند به نظر می رسد هرکجا که یک بی نظ...
In this paper, the Ritz-Galerkin method in Bernstein polynomial basis is applied for solving the nonlinear problem of the magnetohydrodynamic (MHD) flow of third grade fluid between the two plates. The properties of the Bernstein polynomials together with the Ritz-Galerkin method are used to reduce the solution of the MHD Couette flow of non-Newtonian fluid in a porous medium to the solution o...
