    Sustainable processing is now becoming compliance for the Textile industries. Bio-processing is the one of the eco-label fields in the modern technologies. Therefore, this article mainly focuses on new research on biological treatments for pretreatment sector of cellulosic substrate for eco-friendly processes and eco balancing by using various enzymes, instead of harsh & hazardous chemicals. In addition, the future trends in the biotechnology are also discussed in the end of this paper. This paper presents also short introduction to the method of new bio-processes. Biotechnology can be used in new production processes that are themselves less polluting than the traditional processes and microbes or their enzymes are already being used to degrade toxic wastes. The use of enzymes in the textile chemical processing is rapidly gaining  globally recognition because of their non-toxic and eco-friendly characteristics with the  increasingly important requirements for textile manufactures to reduce pollution in textile  production The reduction in pollution load represents a major option for potentially decreasing both the environmental impacts as well as the treatment costs.

    The study attempts to examine the impact of intellectual capital(IC) practices (i.e. human capital, structural capital and relationalcapital practices) on financial efficiency through mediating the roleof bank performance. We collected data for 518 banks’ professionalsthrough questionnaire and use the direct path way and multipleregression to examine the impact of IC practices on mediating variable(bank performance) and mediating variable on dependent variable(financial efficiency). The results reveal that the proposed hypothesesare statistically significant (p<0.01) and that banks’ performancepartially mediates the relationship between IC practices and banks’financial efficiency. This study provides valuable insights on theimpact of IC practices on financial efficiency of banks throughmediation of bank performance. The tested theoretical relationshipreveals that banks which are more involved in IC practices get betterresults than their competitors

In this research, smart controller is intended to regulate the attitude of drone. Simulation ideal model and fuzzy logic control approach is formulated to implement for four elementary motions i.e. roll, pitch, yaw, and height of our drone for the application of earth-quake. The key objective of this research paper is to develop the anticipated output as compare to the desired input

    Wheat Straw Optimization via its Efficient Pretreatment for Improved Biogas Production

    Get PDF
    The complex indigenous configuration of non-bio-labile wheat straw necessitates its pretreatment to optimize the breakdown of its structural components for its ultimate conversion into biogas by means of anaerobic digestion. In this research work, wheat straw was pretreated with potassium hydroxide (KOH) to facilitate its improved biodegradability. The pretreatment of wheat straw was also obvious in terms of its crystallinity resulting in the improved amorphous regions compared to the control wheat straw. The results showed that pretreated wheat straw digestion transpired into comparatively higher removal of TS (86%), VS (89%) and total lignin, cellulose and hemicellulose (22%) than that obtained with control wheat straw. Maximum biogas production accrued was 1550 mLN per day with optimized dosing of KOH compared to 967 mLN per day obtained with control wheat straw, implying that the cumulative biogas production was improved by 45% using pretreated wheat straw than that using control wheat straw. These results suggested that pretreated wheat straw digestion led to a significant improvement in the biogas yield

    Background: Although many causes of malnutrition are discussed in previous studies, the impact of mother schooling on malnutrition among children of rural-urban Pakistan and mediating factors is not posited in case of Pakistan. Hence, this study examine the effect of mother schooling and intervening linkages on acute and chronic malnutrition. Methods: The prior empirical relationship is examined by calculating adjusted risk-ratio with the help of binary logistic regression analyses using a sample size of 3184 rural-urban mothers retrieved from the latest Pakistan Demographic and Health Survey 2012-13 (PDHS). Results: The urban mothers without education are more likely to have stunted and underweighted infants as compared to rural ones. Rural (urban) mothers with poor (moderate) economic position have more chances of having stunted infants than urban (rural) mothers. However, only urban mothers with poor status have more chances of having underweight kids relative to mothers with rich class. The rural mothers with empowerment and with seeking for medical services are less likelihood to have stunted infants than urban ones. Value of the Study: The impact of mediating factors arising from education on rural infants’ health is higher than that on urban infant
