"كَيْفَ تَكْفُرُونَ بِٱللَّهِ وَكُنْتُمْ أَمْوَاتاً فَأَحْيَاكُمْ ثُمَّ يُمِيتُكُمْ ثُمَّ يُحْيِيكُمْ ثُمَّ إِلَيْهِ تُرْجَعُونَ[[1]]

"تم اللہ کے ساتھ کفر کا رویہ کیسے اختیار کرتے ہو حالانکہ تم بے جان تھے، اس نے تم کو زندگی عطا کی، پھر وہی تمھاری جان سلب کرے گا، پھر وہی تمہیں دوبارہ زندگی عطا کرے گا، پھر اسی کی طرف تمہیں پلٹ کر جانا ہے"۔

Interaction of Household Wealth and Women’s Working Status on Child Malnutrition: Evidence from PDHS-2013

Theoretically, it is supposed that women’s working status and household wealth independently contribute towards the children’s dietary status. The working women of the inferior socio-economic class are generally engaged in the informal sector or low paid work. It may be argued that such kinds of service cannot contribute to the nutritious prestige in children. To solve this puzzle whether woman's working status in all socio-economic setups is contributing to children’s nutritional status or not? This is the main focus of the research. A sample data of 1169 households from PDHS (2012-13) are used to explore the influencing factors of child malnutrition. The study employed the binary logistic regression which observes the likelihood of malnutrition in the children. Malnutrition is measured through CIAF. The interaction terms of the woman’s working status and five quintiles of wealth index have been created. The results disclose that working women belonging to the household of the first two quintiles of the wealth index and the fourth quintile of the wealth index are not contributing to the nutritious prestige of the children. Furthermore, in the third quintiles, the working status of women contributes to the nutritional prestige of children. It may be inferred that the socioeconomic status of the household is important for the nutritional welfare of the children, not the woman's employment. However, it may be concluded that women’s employment should be of the level that can support the socio-economic status of the household.

Molecular and Physiological Evaluation of Maize Zea Mays After Chemical Pre-Treatment for Alleviation of Drought Stress

To investigate the effect of foliar application of Ca2+, K+ and H2O2 and subsequent water application on maize seedlings CV Azam, a pot experiment was arranged in completely randomized design at the Institute of Biotechnology and Genetic Engineering, The University of Agriculture Peshawar from 2012 to 2014. Drought stress was enforced by withholding water from half of the pots for 20 days after foliar supplementation of 5, 10, 15mM CaCl2, 25, 50 and 75mM KNO3, 1, 3 and 6mM H2O2 (hydrogen peroxide) and distilled water. The results of this experiment revealed that foliar application of Ca2+, K+ and low concentration of H2O2 (hydrogen peroxide) decreased the excised leaf water loss (ELWL), signifying better water relations and osmotic adjustment. Moreover, water deficit decreased fresh and dry biomass, shoot-root ratio, relative water content (RWC), chlorophyll content, membrane stability, ascorbate content, catalase (Cat) activity, and protein content. Similarly, there was an increase in the H2O2 content, MDA (malondialdehyde) content, cell death, anthocyanin content, proline content, sugar content, thiol content, glutathione content and ascorbate peroxidase (APX) activity. Foliar application of 10mM CaCl2 and 75mM KNO3 improved all these traits under drought stress. Senescence during drought was also delayed in the supplemented seedlings as highlighted by a high RWC, leaf area, chlorophyll content and high antioxidant enzymes activity. The Ca2+ and K+ concentration resulted in a decrease in H2O2 content, MDA content, percentage electrolyte leakage. The Ca2+, K+ and H2O2 induced calcium dependent protein kinase (ZmCDPK1, 2, 3, 11), ZmCat3 and ZmCSD1 expression under irrigated and drought stress conditions. The improved water relations and maintenance of growth in the supplemented seedlings established the potential of CaCl2 and KNO3 to improve crop performance under restricted water regimes without diminution of yield and ensure food production from arid and semi-arid lands. Transcripts abundance offers a base for further crop improvement and enhanced understanding of signal transduction in plants.
