ساخت خمیر کاغذ شیمیایی- مکانیکی از پسماند کلزا با هدف بررسی تاثیر زمان و دمای مرحله فراوری شیمیایی بر کیفیت خمیر کاغذ از ساقه کلزا انجام گرفته است. متغیرهای فراوری شیمیایی شامل دو دمای 125 و 145 درجه سلسیوس و سه زمان 15، 30 و 45 دقیقه و با مصرف 4٪ هیدروکسید سدیم و 8٪ سولفیت سدیم در یک محفظه پخت تحت فشار انجام گرفت. بازده قابل قبول بین کمینه 8/53٪ تا بیشینه 63٪ بود و بازده کل بین 6/57٪ تا 9/68٪ ...
AIM To compare the outcome between patients with jejunoileal atresia (JIA) associated with cystic meconium peritonitis (CMP) and patients with isolated JIA (JIA without CMP). METHODS A retrospective study was conducted for all neonates with JIA operated in our institute from January 2005 to January 2016. Demographics including the gestation age, sex, birth weight, age at operation, the presen...
The effect of 2’-cytidylic acid and 3’qtidylic acid upon the binding of cupric ions by RNase has been studied by gel filtration, together with the effect of cupric ions upon binding of 2’and 3’-cytidylic acids. The results confirm that binding of 2’-CMP by RNase weakens its athnity for cupric ions; reciprocally, binding of cupric ion diminishes the athnity of RNase for 2’CMP. The negative inter...
The terminal sugar sialic acid (Sia) plays a pivotal role in cell-cell interaction and recognition. A prerequisite for the biosynthesis of sialoglycoconjugates is the activation of Sia to cytidine monophosphate-Sia (CMP-Sia), by CMP-Sia synthetases (CMP-Sia-syn). CMP-Sia-syn are conserved from bacteria to man, and have been found to reside in the nucleus of all vertebrate species analysed to da...
Infants diagnosed with allergy to cow's milk protein (CMP) are fed extensively hydrolysed cow's milk formulas, modified soy formulas or even amino acid-based formulas. Hydrolysed rice protein infant formulas have become available and have been shown to be well tolerated by these infants. A prospective open, randomized clinical study to compare the clinical tolerance of a new hydrolysed rice pro...
The ability of soluble C. albicans 20A (serotype A) mannoprotein (CMP) to serve as a ligand for toll-like receptor 4 (TLR4) and its co-receptors was examined using commercially available and stably-transfected HEK293 cells that express human TLR4, MD2 and CD14, but not MR. These TLR4 reporter cells also express an NF-κB-dependent, secreted embryonic alkaline phosphatase (SEAP) reporter gene. TL...
We have used monoclonal antibodies against cell-surface developmental epitopes in combination with micromagnetic beads to isolate phenotypically defined subpopulations of cholangiocyte marker-positive fetal liver epithelial cells (CMP-FLEC). Differentiation potential was evaluated by injecting cell isolates from dipeptidyl peptidase IV (DPPIV) positive (DPPIV+) Fischer donor rats into the splee...
In many-core CMP architectures, the cache coherence protocol is a key component since it can add requirements of area and power consumption to the final design and, therefore, it could restrict severely its scalability. Area constraints limit the use of precise sharing codes to smallor medium-scale CMPs. Power constraints make impractical to use broadcast-based protocols for large-scale CMPs. T...
این تحقیق به منظور استخراج لیگنین از خمیر کاغذ شیمیایی – مکانیکی (cmp) رنگ بری نشده مخلوط پهن برگان و مطالعه ی گروه های عاملی رنگ ساز در آن براساس تیمارهای استیل دار کردن و احیاء کردن، به کمک طیف سنجی ftir انجام گردید. برای استخراج لیگنین از خمیر کاغذ از روش استخراج دیوکسان اسیدی ملایم استفاده شد. برای تیمارهای استیل دار کردن و احیاء کردن لیگنین به ترتیب از اسید استیک و بوروهیدرید سدیم (nabh4) ...
Human immunodeficiency virus (HIV) infection has been associated with cardiac disease, including anatomical or functional disturbance to the heart. Cardiomyopathy (CMP) is one of these disturbances that have been associated with high rates of morbidity and mortality. In this review article, several aspects of potential relationships between HIV infection and cardiomyopathy development have been...
