Great attention has been paid to membrane-based separation technology in various separation fields, including gas separation. It provides the benefits of energy efficiency, environmental friendliness, easy scale-up, and convenience in operation. Different division advancements are being utilized for the expulsion of acid gas carbon dioxide (CO2). The aim of this work is to synthesis the membrane using polyvinyl alcohol (PVA) with treatment (WT) and without treatment (WOT) of the additive that is triethanolamine (TEA), to study the effect of additive on the permeance of membrane towards CO2 and the morphology changes of each membrane. In this research, virgin PVA and PVA with TEA were cast upon the porous support membrane of polyvinyl chloride (PVC). PVA was used as the polymer matrix, and TEA was used as a CO2 facilitating agent. Distilled water was used as a solvent for TEA and PVA in preparing the solution. Dimethyl acetamide (DMAc) and Tetrahydrofuran (THF) were used as solvents for PVC porous membranes. These membranes were tested on CO2 to find out the permeability and flux rates (J). For the morphology of the membrane, we performed SEM; for thermal analysis, we performed DSC and TGA, and for the strength, we performed the tensile test. The results reveal that the presence of TEA changes the morphology and thermal behavior increases the strength and the permeability of CO2. In a nutshell, the presence of TEA enhanced the performance and the morphology of the membrane.

Background: Premature rupture of membranes (PROM) is a leading cause of neonatal morbidity and mortality. Aim: To compare the outcomes of prophylactic versus selective antibiotics in term newborns born after PROM > 18 hours in terms of neonatal sepsis and resistance of neonatal. Study design: Randomized controlled trial. Methodology: This study enrolled (n=120) asymptomatic term (37+ weeks) babies of either gender with PROM > 18 hours after ethical review committee’s (ERC) approval. This study held at DHQ Hospital, Rawalpindi-Pakistan in 2019. Data was collected through a structured proforma with informed consent. Data was analyzed by SPSS, v-20. The study outcomes were neonatal sepsis and resistant neonatal flora. Chi-square test was applied with p≤0.05 taken as significant. Results: The neonatal sepsis was diagnosed in 8 (13.3%) and 9(15%) babies in the prophylactic treatment group and the selective treatment group, respectively having statistically insignificant difference (p>0.05). Likewise, resistant neonatal flora between both groups showed statistically insignificant difference (p>0.05). Conclusion: We concluded that there was insignificant difference in terms of rates of neonatal sepsis and resistant neonatal flora between two treatment groups. However, there is a need to conduct large sample size, multicentre studies to validate these results before making recommendations for routine treatment of full term babies with PROM >18 hours in our clinical settings.
