در این پایان نامه یک تجزیه ul ناقص برای ماتریس a ارائه می شود. این تجزیه iul ناقص به عنوان پیش شرط برای حل دستگاه خطی ax=b به کار می رود.از آنجایی که این پیش شرط به عنوان محصول فرعی الگوریتم bfapinv محاسبه می شود، آن را پیش شرط iulbf می نامیم. به منظور کیفیت پیش شرط iulbf آن را با پیش شرط دیگری به نام iluff مقایسه می کنیم. با بکار بردن فرایند حذف درایه های ماتریس های w،z،l و u، نسخه های متفاوت...
Consider the linear system of equations of the form Ax = b where the coefficient matrix A ∈ Rn×n is nonsingular, large, sparse and nonsymmetric and also x, b ∈ R. We refer to this system as the original system. An explicit preconditioner M for this system is an approximation of matrix A−1. In [1], Lou presented the Backward Factored INVerse or BFINV algorithm which computes the inverse factoriz...
background : studies show that there is association between air pollution and disturbances on normal function of various systems of body. the main aim of this study was to determine the effects of diesel oil vapor inhalation on serum creatine, alkaline phosphatase, sgot and sgpt levels as indices of liver function in male rats. methods: thirty two rats were randomly divided into 4 groups: contr...
Background and purpose: Vascular calcification is an important factor in pathogenesis of atherosclerosis. Studies have shown that alkaline phosphatase increases vascular calcification. Here we investigated the effect of gallic acid on alkaline phosphatase gene expression in vascular smooth muscle cells (VSMCs). Materials and methods: In this experimental study humans aorta VSMCs were incubated...
objectives: osteoblasts are the most important cells in the osseointegration process. despite years of study on dental implants, limited studies have discussed the effect of saliva on the adhesion process of osteoblasts to implant surfaces. the aim of this in vitro study was to evaluate the effect of saliva on morphology and differentiation of osteoblasts attached to implant surfaces. materials...
backgrounds and aims: the purpose of this study was to examine the effects of potassium, sodium and zinc metal ions on ammonium sulfate fraction of acid phosphatase activity of orange fruit. materials and methods: acid phosphatase was extracted and purified from orange fruit and then various samples as well as a control sample were prepared in vitro. in addition to substrates, ions of potassium...
water and soil salinity are two of the most important limiting factors in crop production. phosphatase enzymes are widely found in plants. phosphatase enzymes are responsible for de-phosphorylation of organic phosphate and altering it to mineral phosphate. germination experiments were conducted using two bread wheat cultivars, namely, iniya66 and ghods along with application of different nacl p...
drought resistance is a very important characteristic needed for plant survival especially at germination stage, in arid and semi-arid lands. phosphatase enzymes are widely found in plants. these enzymes are responsible for dephosphorylation of organic phosphate and altering it to mineral phosphate. germination experiments were conducted in two bread wheat cultivars (sardari and alvand) under s...
Background: Hodgkin’s disease (HD) is a neoplastic disease originating in lymphoid tissue, which spreads to lymphoid structures and ultimately nonlymphoid tissues. Lactate Dehydrogenase and Alkaline Phosphatase are increased in blood following membrane cell damage. The aim of this study was to compare Lactate Dehydrogenase and Alkaline Phosphatase levels in children in different stages of Hodg...
