This paper presents the effect of five dissolved inorganic salts (NaCl, CaCl2, ZnCl2, CdCl2 and NH4Cl) on the endothermic enthalpy of mixing of the binary methanol + ethyl acetate system has been investigated at 303.15 K, using an isothermal batch calorimeter with vapour space. The endothermic excess enthalpies of mixing values are significantly increases for the addition of ZnCl2, CdCl2 and CaCl2. For the addition of NaCl and NH4Cl salts are insignificantly decreases the endothermic excess enthalpy values. The experimental values of the enthalpy of mixing were fitted into a Redlich – Kister equation, the deviations and parameters were reported. The experimental and correlation results reveals that the importance of the solvent- solvent and solute-solvent interaction by the enhanced excess enthalpy of mixing (HE) values in the positive direction with increasing concentration of the salts.

Phthalates are one of the more favoured plasticisers in polymer industries. The phthalic acid (benzene-1,2-dicarboxylic acid) diesters an artificial substance with a variety of industrial uses, generally known as phthalates. They are of two types: High molecular weight (HMW) phthalates, like DEHP[di(2-ethylhexyl)phthalate], DnOP(di-n-octyl phthalate), and DiNP(di-isononyl phthalate), which are mainly employed in the manufacturing of flexible vinyl to make them more flexible and pliable, and then used to make goods, placemat and wall coverings, applications that come into contact with devices of medical and food. Low molecular weight (LMW) phthalates, those are use in varnishes and coatings, as well as some times releases medicinal preparations, fragrances, moisturizers, and cosmetics. DEP (diethyl phthalate) and DBP (dibutyl phthalate) are the examples of LMW type of phthalate. Exposure to phthalate esters has increased fear of the health and well-being of women. Several noxious exposures of phthalates have been shown to have an adverse impact on health. In the present scenario phthalates exposure has been recognized. However, among the overall human population women are one of the most vulnerable groups, which are often a victim of self-ignorance. Some of the major health issues frequently observed in women due to phthalate exposure are endometriosis, precocious puberty, hormonal disbalance, obesity etc. Although some studies are available concerning the effects of phthalate exposure on women yet major area remains unaddressed. The present review gives insight into the extent of work performed in the above area along with respective loopholes. Also, an attempt has been made to understand the proper mechanism given by simultaneous researchers throughout the globe. Moreover, the study will enable to help professionals in the field to regulate the extent of exposure along with highlighting the alarming situations as a result of phthalate usage and acquaintance.

The purpose of the study was to determine the extent to which principals’ forms of communication influence students’ discipline in secondary schools in Nandi County, Kenya. The study used systems theory by Ludngvan Bartalanffy. Descriptive survey design was adopted. The study sample consisted of 118 public and private schools’ principals, 108 teacher and 1534 student leaders. Each school provided 13 student leaders. Questionnaires for principals, interview guide for teachers and student leaders were used as instruments of data collection. Data was analysed using SPSS. Descriptive statistics was used to analyse data then, tabulate and present data. The results generated were reported in tables. The study establishes that communication clarity is a key component to adherence of instructions given. The information has highest clarity when given in student baraza. The principal is able to explain himself to the satisfaction of the students and issues raised are promptly answered. The students are able seek clarifications on issues they want sorted out. This enhances discipline. The national and county quality and standards officers should be designed by MOEST to bolstering their assessment capabilities to adequately report accurately on true causes of discipline cases in schools and particularly in Nandi County and give out specific remedies to work out on how to reduce the prevalence.

It gained 29.67 folds purification at this final step. In addition to its beneficial in characterization of glucose in blood; moreover it can destroy microbial strains.

Kenya is vulnerable to natural disasters like floods, which are expected to become more common as a result of climate change. Flooding is one of the natural hazards that is catastrophic in nature and affects human settlements, infrastructure, and livelihoods. The objective of the study was to investigate the factors influencing the integration of GIS, community coping strategies, and local knowledge in flood management in Narok Town, Kenya. This study adopted an analytic cross-sectional study design and an exploratory approach. The study population comprised of households within Narok Town. The sampling unit was a single household while the household head was the unit of analysis. A stratified random sampling technique was used to select 385 households from the different zones in the town. A structured flood coping mechanism questionnaire was used to collect data from the household head while Key informant interview guide and focus group discussion was used to gather qualitative information. Descriptive statistics included the mean, standard deviation, percentages, chi-square test were used to analyze data. Analysis was done using SPSS version 24.0 and Quantum Geographic information System to generate data and information on community coping mechanisms, geospatial patterns of floods, and perception about floods in Narok town. Qualitative analysis was analyzed through the use of secondary literature while quantitative data was analyzed through the inferential statistics Fisher’s exact test, Analysis of variance, correlation, and logistic regression. The study findings showed that there is low integration of household knowledge, coping strategies, and Geographic Information systems in flood management among residents of Narok Town. The study finding established that education, Income, and government policies influenced the integration of local knowledge, coping strategies, and GIS integration in flood management. The finding implied that households’ heads' education, income, and awareness of existing government policy on flood disaster management significantly strengthened integration of local knowledge, coping mechanism, GIS integration in flood management.

Fenugreek (Trigonella foenum-graecum L.) is an annual leguminous crop, which is native to the Indian subcontinent and the Eastern Mediterranean region. Historically fenugreek leaves and seeds were used for many therapeutic purposes. Fenugreek has been used for treatment of mouth ulcers and chapped lips, cure of baldness, in alleviation of abdominal and abscesses pain, in alleviation of cardiovascular and hepatic disorders, treating arthritis, dropsy, heart disease, spleen and liver enlargement, kidney ailments. Various parts of fenugreek are used in different food products due to its diverse and rich constituents. Recent studies on animal models showed that fenugreek has a toxicity on acute large doses and on chronic low doses, despite this; fenugreek still stated as safe by food and drug administration (FDA).

The effect of viscous dissipation and internal heat generation on the Steady two-dimensional radiative boundary layer flow with suspended particulate matter (SPM) of an incompressible viscous fluid past over a semi-infinite flat plate has been investigated. The radiative heat flux is assumed to follow Rosseland approximation. The highly non-linear governing equations have been solved numerically by using finite difference technique with non-uniform grid. Results have been graphically displayed and discussed quantitatively to show the effect of radiation and internal heat generation on boundary layer flow characteristics as well as the numerical values of shear stress and rate of heat transfer are obtained for various values of physical parameter.

Millet is one of the oldest foods known to humans and pearl millet (Pennisetum glaucum) is the most widely grown type of millet. To test the acceptability and cost effectiveness of pearl millet based Indian sweets, establish their nutritional superiority and to promote them among school-going adolescent girls. Pearl millet was selected, procured, cleaned, roasted and milled. The milled flour was sieved repeatedly to get a fine flour. The flour was stored at room temperature in airtight HDPE. The pearl millet flour was incorporated in Indian sweets such as appam, Sweet murukku, Sesame balls, Groundnut balls and Roasted bengal gram balls. Appam (PMA), sesame balls (PMSB), groundnut balls(PMGB) and roasted bengal gram balls (PMRB) contained 40 percent of pearl millet flour and sweet murukku (SPMM) contained 60 percent of pearl millet flour. Their acceptability was evaluated, nutrient content and the Cost Effective Ratio (CER) were calculated. An overall acceptability score percentage of 90 and above was obtained by all the prepared sweets namely, sesame balls, groundnut balls, roasted Bengal gram balls and sweet murukku. Pearl millet appam and control sweet murukku which obtained a score of 86.67 percent and 87.56 percent respectively. The cost of preparation of 100 g of pearl millet based sweets and their control is well below Rs. 10. Pearl millet based Indian sweets are low cost recipes and highly acceptable.

Cocoa pod husk (CPH), is a rich source of minerals (particularly potassium), fiber (including lignin, cellulose, hemicellulose, and pectin), and antioxidants (e.g. phenolic acids). It is composed of mesocarp, endocarp, and epicarp. The mesocarp consists of fiber (crude, NDF, and ADF-44-48%) and cellulose (53%). CPH’s potential application to human health includes antioxidant, anti-inflammatory, anti-carcinogenic, immunomodulatory, vasodilatory analgesic, and antimicrobial activities. Fresh ripe cocoa pod husks were collected, and the mesocarp was separated and air dried followed by size reduction and extraction with acetone: methanol (7:3) (v/v) using the maceration process. GC-MS analysis was carried out to identify the phytochemical compounds present in the extract. The compounds identified in the extract highlight the great potential of the extract to improve life. When tested, the extract showed activity against nine different human pathogens at varying concentrations. Free radical scavenging activity was also determined using ABTS and DPPH assays, and the extract was found to be potent.

The study examined the extent at which Covid-19 pandemic affected families in river state, Nigeria. The study aimed at determining the level of impact on gender and the role of government in ensuring livelihood sustenance in post pandemic era. Crisis affect women, girls, men, boys, and all gender differently, government orders and legislations have disproportionate impact on different gender groups, as well as persons and families. During crises periods such as pandemics, the risk of gender based violence escalates. It therefore becomes imperative to examine these impacts and related consequences of the lockdown so as to help government make social provisions where and when necessary. A total of 200 questionnaires were purposively sent to individuals online. 10 different WhatsApp groups created for group discussions. Abusers were identified and interviews conducted. Data collected were analyzed using the Statistical Package for Social Sciences (SPSSS). Results indicate that due to the prolonged nature of lockdowns in the state with its psychological and emotional outcomes on families, abusers leveraged on the quarantine period as abuse became more frequent and violent, other issues were identified such as increased child abuse, hunger leading to malnutrition. Paper therefore recommends that help-lines be provided for reports of violence and cases of abuse. Government to adopt a systematic/data based palliative distribution for wider coverage. Equal access to COVID- 19 testing, treatment and vaccines as and when they become available.
