خردشدگی ناشی از انفجار نقش بمهمی در کنترل و کاهش هزینههای عملیات بارگیری، باربری و سنگشکنی دارد. بنابراین پیشبینی خردشدگی حاصل از انفجار در طراحی عملیات انفجار بهینه بسیار مؤثر خواهد بود. سد گتوند علیا بزرگترین سد سنگریزهای کشور با هسته رسی است که روی رودخانه کارون در دست ساخت است. بر اساس مشخصات فنی طرح برای مصالح بدنه سد دانهبندی ویژهای در نظر گرفته شده است. بنابراین تأمین مصالح مورد ن...
مقدمه : تشخیص انفارکتوس میوکارد تا حد زیادی بستگی به مارکرهای بیوشیمیایی دارد. هدف این مطالعه بررسی حساسیت و ویژگی فعالیت ck-mb در تشخیص انفــارکتوس میوکارد می باشد. با توجه به اینکه در کتب رفرنس توصیه شده است هر آزمایشــگاهی cut off تشخیصــی خود را با توجه به تفــاوت هایی که در شرایط آزمایشگاه و جمعیت منطقه وجود دارد تعیین کند و فعــالیت ck-mb از اسفند ماه 81 در بیمارستان حضرت ولی عصر (عج) اند...
Let F be a graph and k be a positive integer. With a graph G, we associate the quantity ck,F (G), the number of k-colorings of the edge set of G with no monochromatic copy of F . Consider the function ck,F : N −→ N given by ck,F (n) = max{ck,F (G) : |V (G)| = n}, the maximum of ck,F (G) over all graphs G on n vertices. In this paper we study the asymptotic behavior of ck,F and describe the extr...
The prevalence of circulating macromolecular creatine kinase type 1 (macro CK type 1 or CK-immunoglobulin complexes) is significantly higher in a patient population selected for CK isoenzyme assay than in age- and sex-matched blood donors (n = 1304). In greater than 8000 patients studied, 49 individuals with macro CK type 1 were identified, yielding an overall prevalence of 0.61%. Macro CK type...
The automated (CK)MB1,2/MM1,2,3 isoform measurement, based on electrophoresis, has been simplified to the point that it has become possible to perform this analysis on a 24-h routine basis. We studied analytical aspects of this analysis and its clinical relevance in relation to other biochemical markers (CK total, CKMB activity, CKMB mass, myoglobin, Troponin I and Troponin T) in patients with ...
Monoclonal antibodies have been raised against human heart- and brain-type creatine kinase (CK-MB and CK-BB). We used a low-affinity monoclonal antibody to develop a simple two-step immunoaffinity purification procedure for native CK-MB. Antibodies of higher affinity were used to construct specific two-site immunoradiometric assays for CK-MB and CK-BB. In the assay for CK-MB we used an 125I-lab...
Cytokinins (CKs) are involved in the regulation of plant development including plastid differentiation and function. Partial location of CK biosynthetic pathways in plastids suggests the importance of CKs for chloroplast development. The impact of genetically modified CK metabolism on endogenous CK, indole-3-acetic acid, and abscisic acid contents in leaves and isolated intact chloroplasts of N...
The aim of the present study was to determine the relationship between histopathological lesions and tissue enzymes in chickens affected by Marek's disease.Five apparently healthy chickens(as control group)and 25 chickens affected by Marek's disease were selected. After consideration of history and gross lesions, tissue samples were collected from kidney, liver, heart, ovary, pectoral muscl...
The aim of this study was to determine the degree to which the epidermis and oral epithelium of species other than man express cytokeratin (CK) intermediate filaments, which are markers of epithelial differentiation. Fixed, wax-embedded samples of skin, buccal mucosa and gingiva from rhesus monkey, marmoset, cow, sheep, pig, ferret, hamster, axolotl and trout were tested for CK expression using...
