Novel metallic stainless-steel mesh-supported conductive membrane and its performance in the electro-filtration process
No full textIn this study, we demonstrate the fabrication of a thoroughly metallic electro-conductive membrane by using simple filtration to uniformly coat AgNWs dispersion through stainless steel (SUS)-mesh, which functions both as filter and a flexible conductive substrate. The as-prepared AgNWs networks layer on the SUS-mesh was further strengthened by electroplating Ag layers (P-SUS membrane); exhibiting an overall electrical conductivity of 9.2 x 104 S/m, which is up to 42 times greater than the conductivity of pristine SUS-mesh. The P-SUS membrane exhibited adequate physical durability against chemical and mechanical stresses under prolonged filtration, and high pure water flux of 534 +/- 54 LMH/bar. This electro-membrane displayed the anticipated flux recovery in harvesting microalgae (Chlorella sp. HS-2) when filtration was done with the membrane used as a cathode: micro -sized bubbles, generated from the cathodic membrane, functioned to detach the foulants and recover the relative flux to a significant level. The P-SUS membrane indeed possesses necessary traits that the polymer-support membrane lacks, in terms of not only electrical conductivity and mechanical strength but also filtration per-formance with anti-fouling capability, all of which are of necessity to be considered workable electroconductive membrane.
The role of solar energy and eco‐innovation in reducing environmental degradation in China: Evidence from QARDL approach
No full textIn the past decade, researchers have shifted their interests to explore different ways to mitigate environmental degradation. In that context, the present study explores the role of solar energy and eco-innovation in reducing environmental degradation in China. The study utilized data for the period 1990–2018 and applied the latest available econometric technique, a quantile autoregressive distributed lag model, to determine the impacts of solar energy and eco-innovation on improving China's environmental quality. According to the empirical results, in the long term, solar energy is negatively and significantly associated with CO2 emissions at higher quantiles. Eco-innovation has proven to be the most important channel to mitigate CO2 emissions in China. Eco-innovation is exerting a negative and significant influence on CO2 emissions at all quantiles in the long term. In addition, the population size is causing CO2 emissions to surge significantly at lower quantiles. The empirical analysis reveals that per capita income (PI) is positively associated with CO2 emissions at all quantiles, but it is significant only at higher quantiles in China. We found evidence of unidirectional causality for eco-innovation to CO2 emissions and solar energy to CO2 emissions. However, for population and CO2 emissions, per capita income, and CO2 emissions, we found bidirectional causality. As indicated by our empirical results, solar energy and eco-innovation are the two most effective channels to control CO2 emissions in China. Therefore, policies based on the promotion of eco-innovation and the initiation of new solar energy projects can control emissions and improve environmental quality in China
Gamma radioactivity and Environmental radiation risks of Granitoids in Central and Western Gilgit-Baltistan, Himalayas, North Pakistan
No full textThe study analyzed the gamma radioactivity levels due to radionuclides (226Ra, 232Th, and 40K) by the Gamma-Ray spectrometry method and calculated health hazards in rocks in Central and Western Gilgit-Baltistan, North Pakistan. The results of average activity concentrations of collected rock samples were 714.82 Bq kg−1 for 40K, 44.47 Bq kg−1 for 232Th, and 56.21 Bq kg−1 for 226Ra, respectively. The values of Indoor Excessive Lifetime Cancer Risk ELCR (in) in the samples are much greater than the permissible limit of 1.19 × 10−3. The values are also higher than safe limits for building materials (0.31 × 10−3) for seven samples. According to statistical analysis, the calculation shows the correlation coefficient value higher than the safe limit. Between 226Ra and 232Th correlation coefficient value is (0.92) and 40K and 226Ra correlation coefficient value (0.97) seemed to be positively high value. For Pearson’s correlation p < 0.05 is considered a safe limit but calculations find out the values for p > 0.05. For Absorbed Dose (D), Effective dose (H), Annual Equivalent dose (E), And most important lifetime cancer risk (ELCR) R2 = 0.99 which shows a strong correlation between them. We have concluded that areas, where these rocks are exposed on a large scale, are not suitable for living. The diorite, granite, leucogranite, pegmatite, amphibolite, and gneiss are highly radioactive and should not be used as a building material.
Revitalizing education: unveiling Allama Muhammad Iqbal’s vision for empowering the Muslim ummah
No full textThe revolutionary philosopher Allama Muhammad Iqbal enlightens and encourages the whole Muslim Ummah in general and the Muslims of the Subcontinent specially. Despite being a philosopher and poet, Dr. Mohammad Allama Iqbal addressed the root causes of the issues that plagued Muslim countries by considering and advocating for improvements of the educational system. He believed that reformation & transformation could be done by fostering self-awareness, advancing education, and distributing information. This article aims to clarify the education strategy that results from Iqbal's conception of education. The objectives of the study are: to investigate the views of Iqbal about Educational thoughts; to search out the main purpose of education and design curriculum in the light of Iqbal's Educational thoughts; to explore Suggested Teaching Methodology and the role of an ideal Teacher in Iqbal Philosophy. Qualitative research method is used for the study. Findings of the study showed that Muhammad Iqbal’s educational thoughts indicate holistic approach of nurturing an individual. His study focused on reviving the spirit of intellectualism in academics. Inculcation of spirituality in education system, based on Islamic ideology is the ultimate aim of education. The effect of this aim will be reflected in curriculum design, teaching methodology and personality of the teacher. Muhammad Iqbal's initiative is still applicable today, because education has a worldwide impact on daily life, forming devout believers or people who are seen to be well-advanced

Genetic Evaluation of Spontaneous Miscarriages and Couples through Conventional and Modern Diagnostic Tools
No full textABSTRACT:
Background: Genetic causes of miscarriages have been extensively reported and studied in almost half of the first-trimester pregnancy losses, for the reason genetic investigations of the product of conceptions (POCs) are crucial to help identify possible genetic etiology. This information is helpful for the devastated parents as it provides them with more acceptance of the loss and helps them recognize possible recurrence risks.
Objective: The aim of this study is two folds; the first is to corroborate an alternative molecular test, QF-PCR which is rapid, more economical, and has less failure rate, and the second is to explore potential parental chromosomal abnormalities causing recurrent spontaneous miscarriages.
Methodology: A total of seventy-six products of conceptions (POCs) were obtained from the Gynecology department of Civil Hospital, Karachi. Further blood samples from forty-five couples were also collected in addition to ninety-three maternal blood samples. All of these samples were subjected to amplify short tandem repeat (STR) for common chromosomal aneuploidies (13, 18, and 21). Real-time QF-PCR was performed on 76 POCs on Sansure Biotech Inc, Changsha, China, using primers D13S631 and D13S634 for chromosome 13, D18S386 and D18S535 for chromosome 18, and D21S1411 and D21S1414 for chromosome 21. Parental blood samples were examined by both QF-PCR and karyotyping for cross-checking with their POC. Chromosome 16 was used as an internal control for the amplification of each reaction. Statistical analysis was done by using SPSS version 24.
Results: QF-PCR analysis revealed chromosomal aneuploidies among twenty-nine POCs with the highest number of trisomy 13 followed by trisomy 21 and then trisomy 18 while all the parental samples were normal. Nine cases of chromosomal abnormalities were ruled out through karyotyping from parental blood samples further, a Robertsonian translocation was observed through conventional cytogenetics and interestingly the corresponding POC was found to have trisomy 21.
Conclusion: This study further confirmed QF-PCR as a competent technique to be included in the first line of prenatal diagnostic methods. As QF-PCR was found to be less laborious, has lesser turnaround time, is more economical, and has a low failure rate than karyotyping

Social capital as a determinant of population health outcomes: A global perspective
No full textThis study contributes to the health literature by decomposing health outcomes into three dimensions that are physical health, mental health and well-being of individuals. Where physical health is measured using life expectancy, infant mortality and self-rated health indicators while mental health is measured using stress index and addition of smoking in both males and females. Finally, well-being is measured using the index of happiness. The empirical analysis is conducted using OLS and GMM for 61 countries from 1980 to 2014. Overall results indicate that social capital is positively associated with all dimensions of health outcomes as high trusting individuals report better health outcomes in comparison to low trusting individuals. The results also reveal that the impact of social capital on mental health is stronger than the impact on physical health. Moreover, social capital is more conducive for controlling stress index than producing happiness. The main message of this research is that social capital has the power to influence diverse dimensions of population health. Therefore, the public policies need to focus on social indicators to overcome health disease burden
