This study examined the impact of Bisphenol A (BPA) on the physicochemical and bacteriological characteristics of water in storage tanks in Salem University Lokoja. Borehole water samples were collected from three (3) locations within the University environment and stored in a jerry can for analysis. Total Heterotrophic Bacteria Count (THBC) in water samples ranged from 1.00± 0.30 x104 at week 0 to 8.95±1.00 x104 cfu/ml at week 3, while the total coliform count (TCC) also ranged from 1.30±0.15 x104 to 7.11±0.82 x104 cfu/ml. TCC and THBC were found to be higher than the NSDWQ Standard. The identified isolates from the borehole samples were Escherichia coli, Pseudomonas aeruginosa, Streptococcus faecalis, Bacillus cereus, Staphylococcus epidermidis and Serretia spp. Bisphenol A (BPA) was not detected in week 0, after week 3, components of Bisphenol A detected were methyl chloride, Benzene and Dichlorobenzene and their highest values were 0.054±0.033, 0.021±0.020 and 0.055±0.062 mg/l respectively. The pH, Turbidity, Total suspended solids, BOD and conductivity reduced as storage increased. Magnesium and calcium for sample B were found to have the highest value of 0.31 and 1.73 mg/l respectively. Storage of water for a long period of time should be discouraged as it could trigger increased leaching of BPA into the water which will affect its physicochemical and microbiologically quality. Keywords: Bacteria, Bisphenol A, Storage Water Tanks, Drinking Water Quality.

In this study, the sanitary quality of tap water sources within the University of Port Harcourt was investigated in order to determine its suitability for drinking and other domestic applications. Eight composite samples of tap water were collected from Eight different locations within the three campuses of the University of Port Harcourt using 300 ml-capacity sterile containers. These locations included NDDC Hostel, Sports Hostel, Medical Hostel, NUH Hostel, Dan Etete Hostel, Delta A Hostel, Delta B Hostel and Choba Campus. After collection, water samples were taken to the laboratory for enumeration and identification of Total heterotrophic bacteria (THB), Total coliform (TC) and Faecal coliform (FC) using the membrane filtration method. Result showed that the average THB, TC and FC counts recorded in the tap water samples across the eight locations ranged from 12.4 CFU to 36.7 CFU, 4.3 CFU to 10.1 CFU and 2.8 CFU to 5.2 CFU per 100ml respectively. Bacterial isolates were identified as probably belonging to genera such as Bacillus spp., Klebsiella spp., Enterobacter spp., Staphylococcus spp., Proteus spp., Citrobacter spp., Serratia spp. and Escherichia spp., respectively. Samples from Delta B hostel and Choba campus recorded the lowest and highest THB, TC and FC counts respectively. According to WHO standard, the result of THB, TC and FC counts indicated that the tap water in all eight locations were above the limit acceptable for drinking but within acceptable limit for other domestic use such as bathing and washing.

In recent years there has been increased discussion of the subjective, emotional and sociological factors influencing student choice of university. However, there is a dearth of information exploring what constitutes these feelings. This exploratory paper uses the conceptual model of the servicescape to provide insight into the emotional factors driving student choice. In-depth interviews with prospective students revealed that first impressions really do count. Students are deterred by poor physical environments and excited by enthusiastic staff and students. Most significantly, the study revealed the necessity of a restorative servicescape to provide both a sense of escape and feeling of belonging. This paper contributes to broadening the application of the servicescape model and to a greater understanding of the impact of the environment on prospective students, and creates an opportunity to inform policy by providing university marketing decision makers with a better understanding of what constitutes the university environment and what makes it appealing to prospective students.

A study about the bacteriological and physicochemical quality of borehole water at the University of Port Harcourt was carried out. Eight water samples was pooled from NUH Block B (Under graduate Hostel), Nelson Mandela Block B (Undergraduate Hostel), Intercontinental Hostel (Post Graduate Hostel), Donald Ekong Block C (Post graduate Hostel), Clinical Hostel, Staff quarters (Opposite Uniport Bottling plant), Dan Etete (Undergraduate Hostel) and Gambiama Staff quarters designated as Sample 1 to sample 8 respectively. Physical examination was conducted to as the sanitary and hygiene practices within the collection area. It was observed that the undergraduate hostels had the least sanitary practice. Total counts of heterotrophic bacteria count showed that the highest bacterial count was recorded from Sample 2 with bacterial count of 2.3x104 CFU/ml while the least bacterial count was recorded from sample 8 with bacterial count of 3.0x102 CFU/ml. The isolated bacterial species from the water sources were identified as Bacillus sp., Micrococcus sp., E. coli., Serratia sp., Staphylococcus sp., Enterobacter sp., Citrobacter sp. The presence of coliform bacteria in the sampled water source does not comply with the World Health Organization (WHO) standard for coliform bacteria of zero total coliform per 100 ml of water. The borehole water samples collected had pH values within 5.9-6.85 which does not comply with the WHO recommended range for drinking water standards which should fall between ≥7 to ≤9.2. Nitrate concentration as observed amongst the eight water samples was below the WHO standard of 50mg/l. The Total dissolved solutes was below 0.01 in all the tested waters samples. This study has revealed that borehole water from sampled sources within the University of Port Harcourt is not fit for human consumption without adequate treatment.

Background: The current situation due COVID-19 may cause an eminent impact on mental health because the confinement restrictions. Aims: The aim of this study was to analyze and compare perceived stress, resilience, depression symptoms and coping strategies on the members of University of Campinas, in Brazil, before and during the outbreak of the COVID-19. Methods: Volunteers over 18 years of both sexes, members of the University of Campinas (Unicamp) in Brazil answered instruments related to perceived stress, depression, resilience and coping strategies during final exams at the end of semester during 2018 to 2020. Results: We obtained 1,135 responses (893 before COVID-19 and 242 during COVID-19). The volunteers did not show significant differences for perceived stress, depressive signs and resilience before and during the pandemic. In both periods, men exhibited lower scores for perceived stress and depression and higher scores for resilience when compared to women. Undergraduate and graduate students exhibited higher perceived stress scores, more pronounced depressive signs and lower resilience, and employees and professors presented lower scores for perceived stress, depressive signs and greater resilience. Conclusions: These first months of confinement did not directly affect the scores of perceived stress, depression and resilience, however, each subgroup adapted to the new routine by changing the coping strategy used. This study suggests the importance of monitoring the mental health of member in the university, especially in times of epidemic, in the search for policies that aim to improve the resilience of the population and seek positive and effective coping strategies within the university environment.

The Relationship

Although some attention has been given to student issues at university, the literature on the relationship between social connectedness, achievement motivation and emotional-social learning with student adjustment is relatively limited. Therefore, this study investigates the impact of social connectedness, achievement motivation and emotional-social learning upon the adjustment of students in a university context. In addition, this study looks into the differences in achievement motivation and emotional-social learning levels between the genders. The sample comprised 240 university students, both male and female. According to the findings, the relationship between the study variables does not significantly differ between genders. Emotional-social learning is significant in terms of predicting the adjustment. Furthermore, gender differences were noted in terms of emotional-social learning levels, but not in terms of achievement motivation and social connectedness. The study explores implications of the significance of emotional-social learning in the university environment and makes recommendations in light of these implications.

A study, using four types of water samples ranging from relatively pure stream water to water containing industrial and domestic effluents, was carried out to investigate the effect of storage temperature on four bacterial parameters: total coliform, fecal coliform, fecal streptococcus, and heterotrophic bacteria. In the study, each water sample was cooled immediately after collection to approximately 1.5 °C by storage in crushed ice. At 2-, 24-, 30-, and 48-h intervals, the sample was mixed, and a subsample was removed and tested. Three separate analyses for each parameter were made on each subsample. The data available for statistical analyses contained, in some cases, the values obtained for the three subsamples and, in others, the means of the three values. The data were analysed as replicated data and as part of the entire set. The analysed data indicated (i) that with the exception of heterotrophic populations, more than 75% of the samples were microbiologically stable for at least 24 h, (ii) that at least 50% of samples tested for heterotrophic densities were stable for a minimum period of 24 h, (iii) that the original water temperature and bacterial load do not appear to be consistent factors in the preservation of samples for microbiological analysis, and (iv) that nutrient levels, also, do not seem to be consistent factors in the preservation of water samples for microbiological analyses.

The physicochemical, microbiological and heavy metal studies of water samples obtained from Mbiaso River and Enang Stream were investigated. Water samples were collected from two locations with two sampling points from each location along the course of the water body based on their use by the community and analysed using standard procedures. The results obtained were compared with WHO standards for drinking and recreational water. Aside titratable acidity, titratable alkalinity and BOD, all other physicochemical parameters were within the permissible standards. All the heavy metals concentrations were above the permissible limits except for Lead (Pb) that ranged between 0.01mg/l to 0.05 mg/l for all the sampling points. All the water samples were found to harbor coliforms organisms in numbers greater than the required WHO standards for water except for Enang river that lacked the presence of Vibrio spp. The total viable counts for all the water samples were generally high exceeding the standard limit of 1.0 x 102 cfu/ml for water. The total heterotrophic bacteria count, total coliform count, faecal coliform count and total fungal count ranged between 1.9x104 - 52x104 cfu/ml, 2.3x104 -38 x104 cfu/ml, 1.7x104 - 30x104 cfu/ml and 2.5x104 - 5.3x104 cfu/ml respectively. The total salmonella-shigella counts and total staphylococcus counts were in the range of 0.2 x102-0.4 x102 cfu/ml and 0.3 x102 -0.6 x104 cfu/ml respectively. From the study, it is suggested that some regulations measures be put in place to control pollution of the water while the water be properly treated before use for domestic, potable or recreational purposes.

Water is very crucial for the survival and maintenance of most living organisms. The quality of water available for plant, animal or human use cannot therefore be compromised. This study therefore examined the physicochemical and microbiological characteristics of water samples in Okomu National Park, Edo State, Nigeria. Water samples were collected from four waterholes (three rivers and one stream) for two seasons (dry and wet) using grab sampling technique. These water samples were analysed for physicochemical [temperature, pH, total dissolved solid, electrical conductivity, total suspended solids, dissolved oxygen (DO), nitrate, chloride, phosphate, sulphate, biological oxygen demand (BOD) and chemical oxygen demand (COD)] and microbiological (total coliform and fungal counts) analyses using standard methods. Data collected were subjected to descriptive statistics and T-test at α0.05 and compared with WHO permissible limits. The result showed that the mean COD (both seasons) and BOD (dry season) were above the comparable WHO permissible limit while there was no significant difference in the values of all the physicochemical parameters across the seasons of sampling. Salmonella / Shigella and Staphylococcus aureus were observed to be absent while the total coliform and fungi counts were observed to be higher than the WHO permissible limit for drinking water. The detection of Escherichia coli in the water samples (except Arakhuan stream) is an indication of faecal contamination either of animal or human origin. There was significant difference in total heterotrophic bacteria (t=-4.936) and total coliform counts (t=-2.417) in the waters sampled. Constant monitoring of the waterholes and intensified sensitization of the surrounding communities on ecosystem conservation is needed to protect the park’s ecosystems.

The use of unsafe water supplies and microbial contaminated water may pose serious health challenge to users. The aim of the study was to determine the level of bacterial contamination of the various water sources and the suitability for human use and consumption in University of Calabar Community, Nigeria. A total of 30 water samples were obtained from the University storage tanks and analysed for the presence of bacteria. The level of feacal coliform count, total coliform count and heterotrophic bacterial count was analysed using membrane filtration method and standard culture method on a differential and selective media. The samples were cultured on MacConkey and Nutrient agar. The isolates obtained from the above media were subcultured into slants of nutrient agar. Isolates were subjected to Gram staining and biochemical tests. The feacal coliform, Escherichia coli was isolated from all the water samples. Total coliform counts ranged from 1cfu/ml - 92cfu/ml while total heterotrophic bacterial count ranged from 1cfu/ml to 161cfu/ml. The bacteria species isolated were Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, Pseudomonas aeruginosa, Streptococcus species, Enterobacter aerogenes, Coagulase negative Staphylococcus, Proteus species, Lactobacillus species and Listeria species. The results obtained from this study have shown high level of bacterial load which makes the water unsuitable for human consumption. Further treatment may be needed as the bacteria isolates from the water samples point to feacal contamination which may be due to inadequate treatment of water, contamination while in the storage tanks or passage through contaminated pipes supplying the community. The consumers may be at high risks of enteric bacterial infections.
