Abstract: The investigation on relative strength and the nature of the intermolecular interaction have been done using Ultrasonic method. In our study Density, viscosity, Ultrasonic sound velocities are estimated, further thermo acoustical parameters and their excess values such as, excess adiabatic compressibility (KsE), excess intermolecular free length (LfE),excess free volume (VfE), excess Gibb’s free energy (GE), excess enthalpy (HE) and excess internal pressure (πE) have been measured for propylene glycol in Hexanol for various mole fractions. These results have been explained on the basis of intermolecular interactions between the components in the liquid mixture and correlations among the parameters are discussed. The study indicated that intermolecular hydrogen bond formation is stronger for (0.8 PG+0.2 Hexanol) molar ratio of the binary mixture liquid complex compare to that of other concentrations and hence this mixture is strongly recommended in therapeutical drugs, pharmaceutical industry and for the high heat transferability applications.

Abstract: The experience of COVID-19 Pandemic in the Philippines necessitated lockdowns and\r\ncommunity quarantines. This minimized mobility and resulted in the loss of income among\r\nfamilies below the poverty line making it difficult for them to provide for their daily needs such as food and medicine. These affected families, therefore, relied on relief assistance from the government and other private instrumentalities. But relief operation in this time of pandemic is challenged by limited manpower who will carry on the relief response. Hence, this study was\r\nconducted to determine the dimensions of public participation in relief response during the\r\nCOVID-19 Pandemic in the Philippines. The study utilized a data reduction process using\r\nexploratory factor analysis. To generate data, a total of 250 respondents were conveniently\r\nchosen to answer in the survey instrument with sixty-three items. Data reduction analysis\r\nrevealed that there are eleven dimensions of public participation on relief response based on the\r\nEigenvalues of not less than 0.4. These are the sense of duty, presence of enabling environment,\r\nintegration of disaster response in the educational curriculum, practical and technical capability\r\nbuilding, value for nationalism, provision of material support, accurate information and\r\neducation campaign, resource mobilization, values-orientation, availability of sophisticated\r\ndisaster response equipment, and readiness for collaboration. If these dimensions are considered\r\nin policymaking, more and more citizens will be greatly motivated to participate in the relief\r\nresponse in times of disasters like the COVID-19 pandemic.

Abstract: In Algeria, market gardeners consider the use of pesticides as necessary to manage pests, diseases and weeds during cultivation under greenhouses, in an effort to reduce or eliminate yield losses and maintain a high level of productivity. Despite their popularity and extensive use, pesticides may pose a significant threat to human health and the environment.The purpose of this study is to evaluate market gardeners’ practices and attitudes with regard to pesticide use and to assess the impact of pesticides on human health and the environment. A survey was carried out in Ain Naga (East Ziban) and Doucen (Ziban West). 96 vegetable farmers randomly selected were interviewed from October 2016 to December 2017. The survey revealed that a total of 143 pesticide products were used by farmers surveyed, representing 70 different active substances. According to CLP classification, the majority of active substances have an acute and/or chronic effects for human health and could cause great harm for ecosystems and target and non-target organisms. According to the WHO classification, four actives substances are considered as highly (WHO class Ib) and one extremely (WHO class Ia) hazardous. However, exposure is particularly critical for abamectin (WHO class Ib), since it is the most commonly used by the majority of farmers (79%). Over 60% of the farmers use pesticides lack knowledge and risk perceptions. More than 50% of the farmers presented safety issues when spraying pesticides. While 72% of the farmers encountered at least one symptom of severe poisoning due to pesticide use. Market gardeners are highly exposed to a wide range of pesticides, with a potential effect on their health.

Abstract: The quality of water can certainly influence the soil�s quality, harm most crops, and lead to unusable soil. Indeed, water scarcity and salinity of groundwater used for irrigation are the main constraints for agricultural production in arid and semi-arid areas. Bearing in mind that the agricultural production in EL Ghrous area (Biskra, SE of Algeria) is mainly based on groundwater irrigation, this study aimed to compare the performance of two interpolation methods: Inverse Distance Weighting (IDW) and Ordinary Kriging (OK) for spatial mapping of the electrical conductivity of groundwater used for irrigation and their effects on soil quality in this area. To do so, a total of 59 water samples and 42 soil samples were collected and analyzed in the laboratory. The aim was to apply interpolation methods coupled with a Geographic Information System (GIS) to select the method that would give better performance. This will offer managers an effective tool to better manage water and soil resources, and to monitor the quality of water used for irrigation in the El Ghrous perimeter.

Abstract: Rapid population growth is uncontrollably causing social and environmental strains in the developing nations of the world. The magnitude of this challenge is reflected by the increasing amount of solid and liquid waste generated and deposits. Consequently, common features of the developing nations are massive areas with stinking heaps of uncollected waste disposed carelessly by roadsides and open spaces which are sometimes borne out of non-compliance to waste disposal rules and improper facilities .Till date, environmental sustainability remains a principal goal of the United Nation’s 2030 target. Therefore, safeguarding the environment and health of the South Africa citizens is an issue of utmost importance even though various South African government have implemented different waste disposal avenues for her populace however, inefficiency of these environmental programme in many part of the nation necessitates further effort in the annual household data overview. Therefore, South Africa’s General Household Survey (GHS), 2017 dataset compiled using stratified two-stage design, with a total of 21,225 households from the nine (9) provinces was adopted here. The dataset was compiled using a well-structured questionnaire which were administered to the households to capture elicit information on the various socioeconomic , housing, living conditions, environmental and waste disposal methods among others. Information on the waste disposal methods, environmental problems, willingness to pay for waste disposal were key variables explored in this paper. This is geared towards the proper understanding the concept of waste management and willingness of the South African households to pay for waste disposal. The research utilized is herewith made available and considered of vital use to the public, given some various present and future reuse potentials as well as the explicit policy implications on the environment and health sustainability.

Abstract: This study was driven by the need to identify with the high school English teachers’ perceptions related to bi/multiculturalism in a classroom. This qualitative study involved 20 teachers divided into four interview focus groups. These teachers teach English and were purposively selected to articulate their observations and unease about mother tongue education in one education district of South Africa. Findings point to the main worry of teachers who feel that their universities did not train them adequately to handle this current issue of mother tongue education in the classroom. They also cited political, economic, social and technical challenges in trying to promote multilingualism in the classrooms. Additionally, the learners seemed to still favour English as the main medium of instruction.

Abstract: CD4 cells are important component of the body�s defense mechanism, therefore CD4 cells count is an important indicator of immune function. Human immunodeficiency virus infection attacks the CD4 cells in the blood, causing their number to drop. When that happens, the person�s body cannot fight infections effectively. The individual then becomes vulnerable to attack by opportunistic infections. These infections occur more frequently and more severely in persons living with HIV (PLWH) than in the general population.\r\nHighly active antiretroviral therapy (HAART), when adhered to by PLWH, is capable of suppressing HIV viral replication, thereby reducing the viral population to �lower than detectable level� which eventually results in immunologic recovery and restoration of normal immune function as the number of CD4 cells increase to normal range.\r\nHowever, not all PLWH achieve immunologic recovery. There are factors that affect immunologic recovery. This study, with a sample size of 1203 PLWH, was aimed at determining patient factors which could affect immunologic recovery in PLWH on antiretroviral therapy in public health care facilities in KwaZulu-Natal. Data was collected using questionnaire and hospital patient charts. 64% of the participants were female, 45.5% of had immunologic failure (CD4 cell count <200 cells/�L). CD4 cells count outcome was statistically significantly associated with gender, poor adherence to ART and baseline CD4 cells count. The probability of immunologic failure for those who did not strictly adhere to ART was more than 3 folds higher than those who adhered to ART; and the probability of immunologic failure was more than 8 folds higher for those who had baseline CD4 cells <200 cells/�L than those who had baseline CD4 cells ?200 cells/�L. These therefore affirm the absolute necessity of strict adherence to ART by PLWH as well as highlights the necessity of the WHO HIV treatment policy of �test and treat�.\r\nKey words: Patient, Immunologic, CD4, HIV, Factors, Failure, recovery
