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.
