در سیستم قابهای مهاربندی شده برون محور (واگرا یا EBF (Eccentric Braced Frame))، شکلپذیری مورد نیاز قاب، و نیز بخش عمدهای از جذب و استهلاک انرژی تحمیل شده به سیستم، توسط تیر پیوند (Link) تأمین میگردد، که مقدار آن بستگی به مشخصات و جزئیات هندسی این تیر دارد. بهترین حالت جهت تأمین سختی و شکلپذیری مطلوب، هنگامی ایجاد میشود که تیر پیوند در برش عمل نماید. در این حالت، نقش ضخامت بال، جان و سخت ک...
BACKGROUND Undernutrition is highly prevalent among infants in Uganda. Optimal infant feeding practices may improve nutritional status, health, and survival among children. OBJECTIVE Our study evaluates the socioeconomic distribution of exclusive breastfeeding (EBF) and growth outcomes among infants included in a trial, which promoted EBF by peer counselors in Uganda. DESIGN Twenty-four clu...
Maternal age at first childbirth has increased in most developed countries in the past 20 years. The purpose of this study is to investigate effects of maternal age at delivery and parity on successful initiation of exclusive breastfeeding (EBF). This retrospective study investigated 1193 singleton dyads with vaginal-delivered at 37-42 gestational weeks during January and December in 2011 at on...
Ectopic bone formation (EBF) is frequently found in various tissues and affects the prognosis of diseases accompanied by EBF. Although the mechanism of EBF remains unclear, several local factors that influence the progression of EBF have been proposed. We have been focusing on the role of mechanical stress as a local factor in EBF in spinal ligament tissues, that is, ossification of the posteri...
BACKGROUND AND AIMS Fruit ripening in Malus× domestica (apple) is controlled by ethylene. Work in model species has shown that following the detection of ethylene, the ETHYLENE INSENSITIVE 3 (EIN3) transcription factor is stabilized, leading to an increase in transcript accumulation of ethylene-responsive genes, such as POLYGALACTURONASE1 (PG1). In the absence of ethylene, the EIN3 BINDING F-bo...
The purpose of the study was to determine the relation between quintiles of muscular strength after adjustment for age and body weight, and excessive body fat (EBF) and excessive abdominal fat (EAF) when controlling for cardiorespiratory fitness (CRF) and other potential confounders. A two-phased cross-sectional and longitudinal study was conducted assessing the prevalence and incidence of EBF ...
Accurate interpretation of reported breastfeeding rates is essential in understanding the true picture of a country's breastfeeding status. In Sri Lanka, where the reported exclusive breastfeeding (EBF) rate among infants aged from 0 to 5 months is 75%, accurate understanding of this rate is of the utmost importance. The danger of misinterpreting the data and assuming that Sri Lanka has achieve...
BACKGROUND Exclusive breastfeeding (EBF) improves infant health and survival. We tested the effectiveness of a home-based intervention using Community Health Workers (CHWs) on EBF for six months in urban poor settings in Kenya. METHODS We conducted a cluster-randomized controlled trial in Korogocho and Viwandani slums in Nairobi. We recruited pregnant women and followed them until the infant'...
Transcriptionally silent genes are maintained in inaccessible chromatin. Accessibility of these genes requires their modification by chromatin remodeling complexes (CRCs), which are recruited to promoters by sequence-specific DNA-binding proteins. Early B-cell factor (EBF), which is crucial for B-cell lineage specification, reprograms mb-1 (Ig-alpha) promoters by increasing chromatin accessibil...
PURPOSE A mother's working environment is believed to be a major determinant of exclusive breastfeeding (EBF) practice. We aimed to define the influence of a facility dedicated to breastfeeding and a breastfeeding support program at the workplace on breastfeeding practice. METHODS A cross-sectional study was performed in five workplaces. The inclusion criteria were female workers whose last c...
