Introduction: Medication use during pregnancy is a major concern in India and poor awareness is driven by non scientific information sources. Primary care providers play a role in providing information on risk of teratogenic and folate deficiency birth defects. Aim: To assess Knowledge, Attitude and Practice (KAP) of pregnant women attending antenatal clinic regarding medication use and self-medication during pregnancy. Materials and Methods: This cross-sectional study was conducted on 100 pregnant women attending the antenatal clinic in a tertiary care teaching hospital of Eastern India from August to October 2021. The study looked at sources of drug information, attitudes regarding medication use and practice of medication use and self-medication among pregnant mothers attending antenatal clinic of the hospital. Consenting women were enrolled in the study and the qualitative data gathered from the women were analysed using tools of descriptive statistics. Results: This study included 100 pregnant women with mean age of 22±2.0 years of which 42% were primigravida. Of the participants 80% had atleast high school education. Two third of the mothers 66% cited their family members as source of their drug information and 76% were aware of the risks of selfmedication during pregnancy. Self medication practice was seen in 25% pregnant women mainly with Paracetamol use for pain or over-the-counter drugs to control acid reflux and morning sickness symptoms. All the participants (100%) took their iron and folic acid supplements as advised. Conclusion: The pregnant women attending the hospital showed adequate knowledge and satisfactory practices regarding medication use. Counselling of the mothers attending the clinic regarding drug use and possible harms to the mother and baby can help reduce long-term risks.
In this study, an integrated power and refrigeration plant, based on biomass gasification, has been modeled and analyzed. The producer gas generated by gasification of solid biomass undergoes full combustion in a combustor-heat exchanger (CHX) and heats up compressed air for an indirectly heated gas turbine (GT) cycle. The waste heat of the CHX exhaust is further recovered in a recovery boiler to produce steam for the generator of an absorption refrigeration (VAR) unit. Energetic and exergetic assessments have been performed for this integrated plant. Major plant parameters, viz. GT cycle pressure ratio and turbine inlet temperature were varied to find optimized plant configuration. The results show that at a GT cycle pressure ratio 10, the plant yields highest electrical efficiency of 27% when the GT inlet air temperature is 1100°C. At this point, the plant has the lowest cooling-to-power ratio (CTPR, value being 1.18), although this point also gives best exergetic performance; with a combined exergetic efficiency of 27.6%. The plant also gives lowest exergetic specific biomass consumption of 0.7 kg/kWh and highest fuel energy savings ratio of about 45% at the same point.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
