Analytic Analysis for Oil Recovery During Cocurrent Imbibition in Inclined Homogeneous Porous Medium
This paper focuses on the analysis of cocurrent imbibition phenomenon which occurs during secondary oil recovery process.In cocurrent imbibition, a strongly wetting phase(water) displaces a non-wetting phase(oil) spontaneously under the influence of capillary forces such that the oil moves in the same direction to the water. We use an optimal homotopy analysis method to derive an approximate analytical expression for saturation of water when the viscosity of the non-wetting phase is non-negligible
A socio-demographic profile, growth, nutritional and hygiene status of children of primary and secondary boarding schools of Gandhinagar district: a cross sectional study
Background: A school is a key location for educating children about health, hygiene and nutrition, and for putting in place interventions to promote the health of children. Objectives: of current study were 1) To study the socio demographic profile of children of boarding schools. 2) To study the growth, nutritional and hygiene status of children of boarding schools.Methods: The study was a cross sectional study. After taking the permission of principal of resident schools and consent of the parents of children, 867 children from 8 boarding schools were interviewed during February-March 2011. A self-administered questionnaire was used for data collection.Results: Age of the study children (total 867) ranged from 5-19 years. (Mean age = 13.80 ± 1.96 years). Out of 867, 434 (49.9%) were boys and 433 (50.1%) were girls. 32.6% belonged to socio economic class IV. There were only 122 (14.1%) children who had been in boarding school since 4 and more than 4 years. Good personal hygiene was observed in only 75 (8.7%) children followed by fair personal hygiene in 292 (33.7%) children and poor personal hygiene in 500 (57.7%) children. 220 (50.8%) female children had fair personal hygiene and 343 (79.0%) male children had poor personal hygiene and this difference was statistically significant. Prevalence of malnutrition in this study was 7.2% (Females = 4.2%; Males = 10.1%; P <0.001).The bulk of the malnutrition cases were constituted by the grade-I P.E.M. cases (66.1%) followed by grade-II P.E.M. cases (25.8%) and there were 5 (8.1%) cases of grade-III malnutrition only in female children. Conclusion:Poor personal hygiene, poor nutritional status among these children needs great attention and health education.

Postbiotic production: harnessing the power of microbial metabolites for health applications
Postbiotics, which are bioactive substances derived from the metabolic processes of beneficial microbes, have received considerable attention in the field of microbiome science in recent years, presenting a promising path for exploration and innovation. This comprehensive analysis looks into the multidimensional terrain of postbiotic production, including an extensive examination of diverse postbiotic classes, revealing their sophisticated mechanisms of action and highlighting future applications that might significantly affect human health. The authors thoroughly investigate the various mechanisms that support postbiotic production, ranging from conventional fermentation procedures to cutting-edge enzyme conversion and synthetic biology approaches. The review, as an acknowledgment of the field’s developing nature, not only highlights current achievements but also navigates through the problems inherent in postbiotic production. In order to successfully include postbiotics in therapeutic interventions and the production of functional food ingredients, emphasis is given to critical elements, including improving yields, bolstering stability, and assuring safety. The knowledge presented herein sheds light on the expanding field of postbiotics and their potential to revolutionize the development of novel therapeutics and functional food ingredients
