Introduction: Meconium staining amniotic fluid is associated with lots of adverseoutcome and has long been considered to be a bad predictor of fetal outcome.Objective: This prospective observational study was undertaken to find out immediatefetal outcome in meconium stained liquor.Materials and Methods: This study was conducted in Obstetrics and Gynecologydepartment of Dhaka National Medical Collage Hospital from July to December 2008.The pregnant women with yellow, brown and thinly stained amniotic fluid in labour withgestational age 37 completed weeks were enrolled in the study. Their babies weretaken as case and followed upto 7 days after delivery in National Medical CollageHospital and in Dhaka Shishu Hospital after admission when required. Babies bornwithout meconium stained liquor were taken as a control.Results: Total 80 cases were enrolled in the study as case and 80 cases wereenrolled as control. Mean gestational age was 39.3±1.5 weeks in cases and 38.5±1.3weeks in control. There was 13.8% pregnancy induced hypertension in case groupand 3.8% in control group. Pre-eclampsia were present 10% in case group and 1.1%in control group (p<0.05). Caesarean deliveries were high (75%) in cases and it wasmuch higher with thick meconium (75%) as compared to the thin meconium (25%,p<0.001). Apgar scores in first minute and fifth minute were also low in cases. Birthasphyxia was more in cases (20%). Meconium Aspiration syndrome (25%) andConvulsion (3.8%) were developed only in cases. Admission in neonatal ward wasmore (22.5%) in cases (p<0.05) as compared to control. Neonatal mortality was high(3.8%) in cases than control (1.3%).Conclusion: Meconium stained amniotic fluid were associated with higher rate ofcaesarian delivery, increased need for neonatal resuscitation, increased rate of birthasphyxia with hypoxic ischemic encephalopathy, meconium aspiration syndrome,hospital admission and mortality.Key words: Meconium stained liquor; foetal outcome.DOI: 10.3329/bjch.v33i2.5675Bangladesh Journal of Child Health 2009; Vol.33(2): 41-45

Partial shading of a photovoltaic (PV) installation has an inconsistent impact on power production. This study investigates the effect of partial shading on PV performance. The experiments were carried out with a 90-W PV module under both variable and constant irradiations with shaded area increased from 0 to 80% to observe the effect of variable solar radiation at certain shading points. The effect of shading under irradiation levels from 300 to 800 W/m 2 was investigated. At a 600 W/m 2 irradiation level, the shading impact factor was 1.25 with a 25% shading, while at 75% shading the impact factor decreased to 0.86. Results also show that for every 100 W/m 2 increase in irradiation level, the electrical power output was enhanced by 3.89, 3.37, 2.27, and 2.02 W at 0, 25, 50, and 75% shading, respectively. The efficiency level was increased by 0.29, 0.27, 0.25, and 0.22% at 0, 25, 50, and 75% shading, respectively. Increasing the shaded area by 10% causes a 12.41 W drop in power output and a 2.3% drop in electrical efficiency. Partial shading not only deteriorates the PV performance, but also causes long-term degradation of the module.

Background Developing strategies aimed at reducing behavioral risk factors and hence the prevalence of non-communicable diseases (NCDs) is a major challenge to the policy makers today. Like the same age group worldwide, the prevalence of obesity, unhealthy dietary habit, physical inactivity, smoking and alcohol intake is high among the adolescents of Bangladesh. Studies showed promising results of an early intervention at adolescent age in reducing the likelihood of NCDs at adult age. So, this study is designed to implement a behavior change intervention and evaluate the effectiveness of the intervention in reducing the behavioral risk factors of NCDs among the adolescents of Bangladesh. Methods A before-after designed intervention study will be conducted in two randomly selected secondary schools- one will be selected randomly as intervention school and the another as control school. A baseline survey will be conducted among the students of both schools by a pre-tested questionnaire to attain their current status of knowledge, attitude and practices related to NCDs. Afterward, students will be enrolled in the intervention group who will meet the eligibility criteria from the intervention school. The intervention will be given through a health promotion session to a group of students, not more than 25 at a time, by trained facilitators. A post-intervention end line survey will be conducted among all the participants from both schools using the same questionnaire 3 months after the baseline survey. Discussion An intervention has been developed based on some principals of two psychosocial theory- Motivational Interview and Social Cognitive Theory. Emphasis will be given on motivating the adolescents towards a healthy lifestyle, supporting self-efficacy to be changed, guiding self-regulatory ways along with facilitating desired changing process by empowering them with choices about the preventive measures of NCDs. This intervention is expected to increase awareness by equipping the adolescents with specific knowledge and skills and thus, facilitate an eventual change in their practiced risk behaviors. Besides, this intervention will address multiple behaviors at a time, and will be delivered to a group of adolescents, to attain the cost-effectiveness and thereby making it more realistic in the resource-poor context of Bangladesh.
