Effect of Heat Treatment on Changes In The Crystalline Domains In Mylar Film

Changes in the crystalline domains caused by heat treating Mylar filmsbetween Tg to 240 oC have been studied by Fourier Transform Infraredspectroscopy (FTIR) and X-ray Diffraction (XRD). Prior to glass transition temperature, shrinkage in the film is insignificant, but progresses rather abruptly as melting point is approached bringing the smooth film surface to rather wrinkle.The absorbance increase in the FTIR spectra is due to the thickened film caused by shrinking rather than the improvement in the crystalline orientation. XRD on the other hand show that heat treatment of the film near melting point only reduces the contribution of the crystalline domains in the direction [100] in favor of other direction namely rather than on the account of loosing order in favor of the amorphous regions

Anti-plasmodial and chloroquine resistance suppressive effects of embelin

Background: Emergence of chloroquine (CQ) resistance among different strains of Plasmodium falciparum is the worst catastrophe that has ever perplexed the dedicated efforts to eradicate malaria. This urged the scientists to search for new alternatives or sensitizers to augment its antiplasmodium effect. Materials and Method: In this experiment, the potential of embelin, isolated from Embelia ribes, to inhibit the growth and sensitize CQ action was screened using SYBRE-green-I based drug sensitivity and isobologram assays, respectively. Its effect on red blood cells stability was screened to assess its safety. To explore its molecular mechanism, its effect on plasmodial Hemozoin and the in vitro β-hematin formation was screened as well. Furthermore, its anti-oxidant activity was measured using the conventional in vitro tests and its molecular characters were obtained using Molispiration program. Results: The results showed that its anti-plasmodial effect was weaker than CQ but synergism was obtained when they were combined at ratios lower than 5:5 CQ/embelin. Furthermore, β-hematin formation was inhibited by embelin without showing any synergism after mixing with CQ. Conclusion: Overall, embelin is not ideal to be suggested as a conventional antiplasmodium but it has a potential to ameliorate CQ resistance. Furthermore, its action is not related to its impact on hemozoin formation. Further, investigations are recommended to illustrate its detailed mechanism of action

Genetic and Morphological Diversity Assessment of Five Kalanchoe Genotypes by SCoT, ISSR and RAPD-PCR Markers

Determining the appropriate parents for breeding programs is the most important decision that plant breeders must make to maximize the genetic variability and produce excellent recombinant genotypes. Several methods are used to identify genotypes with desirable phenotypic features for breeding experiments. In this study, five kalanchoe genotypes were morphologically characterized by assessing plant height, number of inflorescences, number of flowers, flower length, flower diameter and number of petals. The analysis showed the distinction of yellow kalanchoe in the plant height trait, while the orange kalanchoe was distinguished in the number of inflorescences, the number of flowers and flower length traits, whereas the violet kalanchoe possessed the largest flower diameter and the highest number of petals. The molecular profiling was performed by random amplified polymorphism DNA (RAPD), inter-simple sequence repeats (ISSR) and start codon targeted (SCoT)-polymerase chain reaction (PCR) tools. Genomic DNA was extracted from young leaves and the PCR reactions were performed using ten primers for each SCoT, ISSR and RAPD marker. Only four out of ten primers showed amplicon profiles in all PCR markers. A total of 70 bands were generated by SCoT, ISSR and RAPD-PCR with 35 polymorphic bands and 35 monomorphic bands. The total number of bands of RAPD, ISSR and SCoT was 15, 17 and 38, respectively. The polymorphism percentages achieved by RAPD, ISSR and SCoT were 60.25%, 15% and 57%, respectively. The cluster analysis based on morphological data revealed two clusters. Cluster I consisted of violet and orange kalanchoe, and cluster II comprised red, yellow and purple kalanchoe. Whereas the cluster analysis based on molecular data revealed three clusters. Cluster I included only yellow kalanchoe, cluster II comprised orange and violet kalanchoe while cluster III comprised red, and purple kalanchoe. The study concluded that orange, violet and yellow kalanchoe are distinguished parents for breeding economically valued traits in kalanchoe. Also, the study concluded that SCoT and RAPD markers reproduced reliable banding patterns to assess the genetic polymorphism among kalanchoe genotypes that consider the basis stone for genetic improvements in ornamental plants

Mapping 123 million neonatal, infant and child deaths between 2000 and 2017

Since 2000, many countries have achieved considerable success in improving child survival, but localized progress remains unclear. To inform efforts towards United Nations Sustainable Development Goal 3.2—to end preventable child deaths by 2030—we need consistently estimated data at the subnational level regarding child mortality rates and trends. Here we quantified, for the period 2000–2017, the subnational variation in mortality rates and number of deaths of neonates, infants and children under 5 years of age within 99 low- and middle-income countries using a geostatistical survival model. We estimated that 32% of children under 5 in these countries lived in districts that had attained rates of 25 or fewer child deaths per 1,000 live births by 2017, and that 58% of child deaths between 2000 and 2017 in these countries could have been averted in the absence of geographical inequality. This study enables the identification of high-mortality clusters, patterns of progress and geographical inequalities to inform appropriate investments and implementations that will help to improve the health of all populations

Turkish-Egyptian economic relations 2011-2013 AD

The economic relations between the two countries have gone through important stages, as we note the great development in relations, especially after the success of the Egyptian revolution on January 25, 2011. The golden stage in the two countries’ economic relations was during the rule of the Muslim Brotherhood, during the rule of President Mohamed Morsi. Investments and commercial relations in  Introduction to the economic relations between the two countries, which were of great importance in the development of economic relations, and the political relations between the two countries did not witness the development that the economic aspect witnessed

Hilla management in the Abbasid era 495-656 AH / 1101-1258 AD إدارة الحلة في العصر العبـــاسي 495- 656هـ/ 1101-1258 م

This research is an attempt to study the conditions of Hilla administrative since it established year 495 AH / 1101 AD until the end of the Abbasid era in 656 AH / 1258, Since Hilla is one of the Important Iraq cities that contributed to the political, social and economic events and had a big role in weakening the Seljuk power in Iraq, and that the reason of building it was politically and administratively represented in the desire of its founder Prince charity bin Mansour Mazeedi in maintaining its influence and achieve its goal of secession from the Seljuk State, when he saw suitable conditions because of the large number of funds and preoccupation with the sultans of the Seljuks in the ongoing disputes; for that he established Hilla and taken home to the emirate in 495 AH / 1101 A
