طراحی کامپوزیت پایه سیمانی مهندسی شده با الیاف پلی وینیل الکل با رفتار سخت شدگی مجدد و ترک های متعدد
کامپوزیت سیمانی مهندسی شده (ecc) نوع پیشرفتهای از کامپوزیتهای سیمانی مسلح به الیاف با ظرفیت کرنش کششی بالا ناشی از رفتار سختشوندگی کرنشی و ترکخوردگی مویی متعدد است. مهندسی مواد در eccاز ارتباط میان میکروسازهها، پروسه ساخت، مشخصات مصالح و کارایی تشکیل شده است. در واقع میکرومکانیک برقرارکننده پلارتباطی میان ویژگیهای مکانیکی کامپوزیت و مشخصات مصالح میباشد. پارامترهای میکرومکانیکی براساس ا...
This study examined the effects of various levels of dietary encapsulated choline chloride (ECC) on growth performance, carcass characteristics, serum and liver lipids content in Ross 308 broilers. A total of 480 day-old broilers were assigned to eight dietary treatments with six replicates of 10 birds each from 1 to 21 days of age. Eight experimental diets were provided from a basal non-added ...
بررسی پاسخ های هورمونی حاد نسبت به فعالیت های انقباضی کانسنتریک، اکسنتریک و کانسنتریک-اکسنتریک در مردان جوان سالم چکیده: مقدمه: تمرین مقاومتی، یک محرک قوی برای افزایش حاد غلظت هورمونهای در گردش خون نظیر هورمون رشد (growth hormone) ، تستوسترون (testosterone) و کورتیزول است. بطور معمول تمرین مقاومتی شامل توالی انقباضاتeccentric (ecc) و concentric(con) می باشد که در برابر بارگذاری ثابت خارجی انجام...
We formulate a framework for applying error-correcting codes (ECC) on multi-label classification problems. The framework treats some base learners as noisy channels and uses ECC to correct the prediction errors made by the learners. An immediate use of the framework is a novel ECC-based explanation of the popular random k-label-sets (RAKEL) algorithm using a simple repetition ECC. Using the fra...
The pseudo strain-hardening behavior of fiber reinforced engineered cementitious composites (ECC) is a desirable characteristic for it to act as a substitute for concrete to suppress brittle failure. The use of ECC in the industry is, however, limited by its high cost. To achieve higher cost/performance ratio, ECC can be strategically applied in parts of a structure that is under relatively hig...
background: early childhood caries (ecc) is a severe type of dental caries affecting infants and pre-school children. because of the infectious nature of the disease, the immunologic response by the host plays an essential role in its development. objective: this study investigated the association between the presence of salivary scd14 and ecc. methods: this study was carried out on 40 healthy ...
AIM This was to assess the prevalence of Early Childhood Caries (ECC) among preschool children attending nursery schools and to compare the results with those of a previous survey where the investigators used the term and diagnosis for Baby Bottle Tooth Decay (BBTD) syndrome. METHODS A cross-sectional survey of 1006 children aged 1-6 years was carried out. WHO recommendations for oral health ...
Methods For this study, tagged MRI images (see Fig.1) were acquired from canine hearts while pacing with standard cardiac gated, breath-hold, cine SPGR, no echo sharing or interpolation, in a 1.5T cardiac scanner. (GE Medical Systems). Following myocardial and tag segmentation a four-dimensional B-spline based parametric motion field was computed for a volume of interest encompassing both ventr...
Background: The infectious nature of severe early-childhood caries (S-ECC) points to the possible participation of immunologic host responses including neutrophils and their antimicrobial products. Objectives: The aim of this study was to determine the neutrophil apoptosis, α-defensins (HNP1-3) and calprotectin levels in the saliva of preschool children and the association with S-ECC. Methods: ...
OBJECTIVE This paper sought to investigate whether early childhood caries (ECC) prevention guidelines were able to produce a significant, long-term, homogeneous decrease in ECC prevalence/incidence within all socio-economic strata of the population and whether their development followed methodologies specifically designed for ECC prevention guidelines. METHODS ECC prevention guidelines and sp...
