Study Design: Prospective observational study. Place and Duration of Study: Gynae/Obs Department, Combined Military Hospital Bannu, from Jan 2018 Sep 2019. Methodology: A total of 134 patients fulfilling inclusion criteria were included in the study. Patient management was multidisciplinary. Convulsions were controlled by 4gram magnesium sulphate intravenously over 20 minutes as a loading dose, followed by 1gram per hour of maintenance infusion. Blood pressure was controlled with injection Labetalol 10 milligram followed by injection Hydralazine repeated after every 20 minutes till the blood pressure was controlled. Results: A total of 134 patients had eclampsia constituting 6.8% of obstetric admissions. Case fatality was 14 (10.4%) while 120 (89.55%) of the cases responded well to treatment and survived the event. Mean age of patients was 22 years. ...

It is imperative to understand the synthesis, processing conditions, and thermal degradation mechanism of the co- as well as terpolymers. This paper reports the in-situ synthesis and thermal degradation studies of the ethylene-propylene copolymer and ethylene-propylene-1-hexene terpolymer and its nanocomposite with ZnAL LDH sheets. The 1-hexene dosing during the in-situ process influenced the product yield and immensely affected the thermal stability of the resultant polymer. One milliliter 1-hexene in-situ addition increased the product yield by 170 percent, while the temperature at 10 percent weight loss in TGA was dropped by about 60 °C. While only 0.3 weight percent ZnAL LDH addition in the terpolymer improved the thermal stability by 10 °C. A master plot technique and combined kinetics analysis (CKA) were deployed to access the thermal degradation mechanism of the synthesized polymers.

One of the common characteristics of preclinical genetic experimentation is the result of repeated measurements, and for this purpose, repeated measurements designs (RMDs) have gained much more significance. In the class of RMDs, balanced repeated measurements designs (BRMDs) are preferred as they balance out the residual effects since the experimentation is repeated over time on different subjects. This study provides the theoretical framework of universal optimal criteria proposed by Kiefer (1975) for the newly proposed circular balanced repeated measurements designs (CBRMDs) by Rajab et al. (2018). These universal optimality criteria were proved for the special class of designs where the number of treatments is equal to the number of periods. Universal optimality has been discussed considering all the possible effects in the models, i.e., units, subjects, treatments, and periods. Methodology. This study characterized CBRMDs, where several treatments and periods are eq...

NiFe LDHs were synthesized with different intercalated anions using the coprecipitation method. The EP/LDH nanocomposites showed improved thermal stability, nevertheless, the various types of intercalated anions in the LDH showed a remarkable effect on the thermal stability and the degradation mechanism of the resultant polymer nanocomposites. EP/LDH constituted with NiFe‐CO3/A (A = acetone washed) showed maximum improvement in the thermal stability concerning neat EP. The LDH incorporation in the composite influenced the polymer microstructure which was evident from the DSC and CRYSTAF analysis. The degradation kinetics of neat EP and EP/LDH nanocomposites were studied by employing the isoconversional method. The degradation kinetics models of different polymer samples were predicted by applying a generalized mast...

Study Design: Comparative prospective study. Place and Duration of Study: Gynecology and Obstetrics department Combined Military Hospital Bannu, from Dec 2017 to Dec 2018 Methodology: Initially 215 patients were enrolled; who were planned for cesarean section under spinal anesthesia but in 8 patients spinal was converted to general anesthesia, while 7 patients refused to participate in trial. Patients were randomly allocated by lottery method to each group. Women in the early feeding group were allowed to start oral sips of fluids 2 hours post operatively while in delayed feeding group oral fluids were started after 12 hours. Primary outcome measures were hospital stay and patient satisfaction. Secondary outcome measures were nausea, vomiting, passage of flatus, and return of bowel sounds. Res...

(CC), digested municipal solid waste (DMSW) and their mixtures using thermogravimetric analysis and mass spectrometry.RESULTSThermogravimetric/differential thermogravimetric analysis indicated three major weight loss stages: dehydration (50–150 °C), thermal degradation of structural components (150–550 °C) and char decomposition (550–800 °C). The gases released during the process mainly contained CO, CH4, CO2 and H2 as main components. Also, with an increase in the composition of CC, the hydrogen yields were noticed to increase. Model‐free isoconversional methods, the Kissinger–Akahira–Sunose and Friedman methods, were considered to identify the activation energy. The kinetic results showed that an increase in the percentage of CC in the mixture lowered the activation energy. The activation energies recorded for CC, DMSW, CD‐1, ‐2 and ‐3 were 282....

The values of SRHT andPLT were separately compared to the respective values of UCS so as to find the linear relations. On the basis of the R2value of Regression Analysis, it has been found that a strong correlation with a high degree of accuracy exists betweenPLT and UCS while the degree of accuracy between SRHT and UCS was found to be low.

The optimization study is carried out using response surface methodology with central composite rotatable design (CCRD). The ANOVA study concludes that the second degree polynomial model is fitted well to the fifteen experimental runs based on p-value (0.003), R (0.97) and Adj-R (0.914). The study shows that the temperature is the most significant process variable to the leaching concentration of Cu followed by nitric acid concentration. However, ultrasound power shows no significant impact on the leaching concentration. The optimum conditions were found to be 20% nitric acid concentration, 48.89 °C temperature and 5.52 W ultrasound power for attaining maximum concentration of 97.916 mg/l for Cu leaching in solution.
