Abstract: Vegetables are important sources of minerals that are essential for life processes. Metal toxicity occurs when there is an elevated level of essential minerals or heavy metals in the body. Vegetables take up metals by absorbing them from contaminated soils and polluted environments. The mineral and heavy metal content were determined in ten (10) selected vegetables obtained from south eastern Nigeria. The vegetables include Telfairia occidentalis, Vitex doniana, Pterocapus santahnoides, Ceiba pentanda, Colocasia antiquorum, Curcurbita pepo, Corchorus olitorus, Mucuna Puriens, Amaranthus hybridus and Lecaniodiscus cupaniodes. The mineral content was analyzed using FS240AA agilent Atomic absorption spectrometer while the heavy metal analysis was done using varian AA240 Atomic absorption spectrophotometer. From the mineral analysis, the vegetables are rich in magnesium with appreciable levels of potassium, calcium and phosphate. Heavy metals such as Iron, Zinc,....

Abstract: This paper reports on a post-occupancy evaluation carried out on the only female students' hostel at Waziri Umaru Federal Polytechnic, Birnin Kebbi, in North-west Nigeria. The researchers aimed to assess the performance of the building, which has been occupied for nearly two decades. They pursued this by measuring occupants' satisfaction with identified variables like accessibility and circulation, occupation density, cleaning and maintenance of the hostel, space performance, and proximity to essential facilities in the institution. The academics collected data via interviews and structured questionnaires administered randomly to occupants on every floor and wing of the hostel. The authors analyzed the data obtained and calculated the Relative Satisfaction Indexes (RSI) for respondents on both floors of the building. Results show that the performance of the hostel is less than satisfactory in respect of most variables examined

Abstract: Post-occupancy evaluation (POE) of students' residences is a growing practice. The paper presents a review of literature on post-occupancy evaluation of on-campus residential facilities for students in Nigeria's tertiary schools. The study aimed to collate and articulate information on POE of students' dwellings that could be useful for informing future projects. Areas covered include POE essence, methods, benefits, and challenges. The researchers pursued the goal by primarily reviewing existing literature on the subject. These information were then integrated into a whole. The study found that POE is impeded by self-preservationist disposition of professionals. Benefits of POE according to the study include the possibility of energy consumption minimization in students' hostels. The study concluded that POE would make a difference in the lives of campus dwellers if carried out routinely.

Abstract: The goal of the study was to investigate the health vulnerabilities among the disaster affected children in coastal area of Bangladesh. Bangladesh is one of the disaster prone areas in the world. Disaster occurs here almost each and every year. As a result, the people of our country especially the children face different problems due to natural disaster. Health problem is the most of them. To achieve the objectives, 125 children (90 boys and 35 girls) were selected by random sampling, from two villages naming Kalabogi and Sarbatkhali under Dacope upazila in Khulna district from January to June 2016. It was an explanatory study by which the face to face interview administered with an interview schedule on the children below the age of 18 years. The findings of the study described that most of the children of the study area were very much physically vulnerable which lead them with bad health condition. Most of the children (82.4%) used hanging latrine and a significant portion of the children (37.6%) washed their hands after toileting by the ash. So, it is high time GOs and NGOs initiated programs on water supply, sanitation, hygienic practices, and proper medical facilities in this area for their better condition.

Abstract: Seventeen marketed brandsof black tea of Bangladesh (viz; Seylon, Tetley, Duncan, National, Fresh, Teer, Finlay, Starship, Ispahani, Cosmo, Magnolia, Danish, Shaw Wallace, Pusti, Kazi&Kazi, HRC and Lipton Taaza tea) randomly collected from the local supermarkets were evaluated for catechin status. The experiment was done in 2015, 2016 and 2017 for determining the catechins [catechin (C), epicatechin (EC), epicatechingallate (ECG), epigallocatechin (EGC), epigallocatechingallate (EGCG), gallocatechin (GC), gallocatechingallate (GCG), non-gallated catechins (NGCs), gallated catechins (GCs) and total catechins (TCs)].All the studied qualitative parameters was found to vary significantly (P<0.05) with the marketed brands of tea. Maximum amount of C, EC, ECG, EGC, EGCG, GC, GCG, NGCs and GCs in all the seventeen marketed brand teas of Bangladesh were determined.......

Abstract: The Pollutant standards indices (PSI) is a sub air quality index (sub-AQI), a number which indicates the concentration level of each pollutant in the air. Pollutant standards indices (PSI) were computed using concentrations of criteria pollutants (SO2, NO2, CO, PM10 and PM2.5). The concentration of air pollutants that present in the atmospheric air which exceeds the regulatory limits in Port Harcourt and its environs and with long time exposure constitute harm to human health and degradation of environments. Despite the global effort to curtail the discharge of air pollutants into the atmosphere, the tremendous increased in air pollution with rapid population growth and corresponding anthropogenic activities require developing of the air quality index modelof our environment. The prime objective of this work is to study the air quality status of Port Harcourt city and its environs by developing pollutant standard index (PSI) andAir Quality Index (AQI) models. Results of AQI indicated that, Eleme, Obio/Akporand Port Harcourt areas are more polluted than Oyigbo, Ikwerre and Etche in the wet season.

Abstract: The paper assessed the quality of facilities and services provided by hotels in Ado-Ekiti, the research employed the use of survey research method; it involved the use of a well structured questionnaire to elicit information from respondents. Purposive sampling technique will be used to select three (3) star hotel as the sample for the study. The reason for making use of the purposive sampling was because the researcher feels its right to use 3 star hotel for the research. Three (3) star hotels are the ones that have at least some average facilities that can be maintained. In all the 3 star hotels in Ado Ekiti, a total sample of 20 hotels were selected for the study using convenient sampling technique which form 10% of the total population of the hotels in the study area, The patrons who responded to the questionnaire were selected with the use of convenient sampling technique. A total of 4 patrons were selected from each of the 20 hotels. However, the researcher was able to retrieve 79 out of 80 copies of questionnaire....
