در این مقاله مدلی برای آنالیز صحیح تیر رابط در قابهای ebf ارائه شده است. در این مدل جان و بال تیر رابط i شکل به طور جداگانه مدل میشوند. ماتریس سختی المان جان تیر رابط شبیه المان غشائی است و از روش اجزاء محدود محاسبه شده و توسط روش گوس در 8 نقطه انتگرال گیری میشود. همچنین این المان در نقاط گوس قابلیت جاری شدن دارد که به این ترتیب میتوان جاری شدن جان تیر رابط را بررسی کرد . همچنین در المانهای تیر...
Background Despite consistent evidence showing the importance of exclusive breastfeeding (EBF) for six months, it remains a sub-optimal practice in The Gambia. This study aimed at investigating the determinants of EBF knowledge and intention to or practice of EBF. Methods A cross-sectional study was conducted among 334 women receiving care at the Edward Francis Small Teaching Hospital (EFSTH)...
The development of the infant intestinal microbiome in response to dietary and other exposures may shape long-term metabolic and immune function. We examined differences in the community structure and function of the intestinal microbiome between four feeding groups, exclusively breastfed infants before introduction of solid foods (EBF), non-exclusively breastfed infants before introduction of ...
BACKGROUND The practice of exclusive breastfeeding (EBF) is influenced by maternal knowledge and attitudes as well as socio-demographic and cultural factors. This study assessed knowledge, attitudes and practice of EBF among rural lactating mothers with infants aged 0-6 months. Factors associated to the practice of EBF were also investigated. METHODS This cross-sectional study was conducted a...
BACKGROUND Empirical data showing the clear benefits of exclusive breastfeeding (EBF) for HIV prevention are needed to encourage implementation of lactation support programs for HIV-infected women in low resource settings among whom replacement feeding is unsafe. We conducted a prospective, observational study in Lusaka, Zambia, to test the hypothesis that EBF is associated with a lower risk of...
OBJECTIVES To ascertain determinants and impact of the duration of exclusive breastfeeding (EBF) for four to six months on growth and incidence of respiratory tract and diarrhoeal infections DESIGN AND SETTING A descriptive cross-sectional study of infants aged 4-6 months, visiting selected well baby clinics in Colombo. MEASUREMENTS An interviewer administered questionnaire to determine dur...
The duration of exclusive breastfeeding (EBF) is often defined as the time from birth to the first non-breast milk food/liquid fed (EBFLONG), or it is estimated by calculating the proportion of women at a given infant age who EBF in the previous 24 h (EBFDHS). Others have measured the total days or personal prevalence of EBF (EBFPREV), recognizing that although non-EBF days may occur, EBF can b...
In most aphid species, facultative parthenogenetic reproduction allows rapid growth and formation of large single-genotype colonies. Upon predator attack, individual aphids emit an alarm pheromone to warn the colony of this danger. (E)-beta-farnesene (EBF) is the predominant constituent of the alarm pheromone in Myzus persicae (green peach aphid) and many other aphid species. Continuous exposur...
OBJECTIVE To assess the relationships between maternal breast-feeding intention, attitudes, self-efficacy and knowledge at 7 months' gestation with exclusive or full breast-feeding at 3 months postpartum. DESIGN Prospective cohort study with structured home interviews during pregnancy and 3 months after delivery. SETTING Two rural sub-districts of Kishoreganj district, Bangladesh. SUBJECT...
The rate of Exclusive Breastfeeding (EBF) varies from 23% to 47% in Iran. Few studies have utilized an appropriate theoretical framework to investigate the continuation of EBF behavior. Resorting to the theory of planned behavior (TPB), this study was carried out to determine factors affecting EBF among women referred to health centers. Using multi-stage sampling method, 373 women were selected...
