Optimization of process parameter to improve on weld joint quality has been at the centre of global research. Some optimization methods have produced welds of low strength and quality whereas , some have made remarkable improvements on the quality of welded joints. In this study, the SWARA-ARAS method was adopted to access its effect on the quality of the obtained welded joints. Stepwise Weight Assessment Ratio Analysis (SWARA) method was used to determine the geometric mean of weights for each of the output parameters that is the mechanical test and measurement results. Additive Ratio Assessment (ARAS) was applied to optimize these parameters by utilizing the weights generated by using SWARA. From applying the SWARA-ARAS method, weldment was found to possess the best input and output parameters

Waste disposal has become one of the major concerns for our Country, Nigeria. Fruit peels are the major solid by-product. The dried fruit peels have a content of cellulose and hemicelluloses, which make it suitable as fermentation substrate when hydrolyzed. This thesis aims at utilizing fruit (pineapple) peels for the production of bio-ethanol by using the yeast Saccharomyces cerevisiae, thus, producing a valuable product from the fruit peel wastes. The pineapple waste is collected and weighed. This is then grinded, mixed with about 2 litres of water and then filtered. The filtrate is heated on the stove for 5-6hours in which sugar syrup is obtained.

After this, fermentation process takes place which involve introducing 10ml of the yeast into the mixture and mixing with 100ml of water. The water is first boiled at 100°c for 30 minutes after which it was allowed to cool to around 37°c.

Finally, distillation process is being carried out. The cold mash is put into the combustion chamber and heat is applied from a stove and a copper pipe connected through the condenser Chamber, thermometer, and cork fitted to the collection chamber. Re-distillation is carried out to increase the ethanol content.

Good health is central to human happiness and well-being. Quality health is necessary for the maintenance and improvement of standard of living which in turn increases productivity, reduces high rate of absenteeism either towards ones occupation or academics, Improves academic performance and reduces the transmission of common diseases. Health Centre’s are community-based and patient-directed organizations that deliver comprehensive, culturally competent, high quality primary health care services. The purpose of the study was to assess the level of utilization of the University health Centre among full time undergraduate of the University of Benin. The study discusses important aspect such as concept of PHC, declaration of Alma- ata, overview of health Centre, utilization of health Centre, service utilization and health seeking behaviour, perceived factors influencing the non- utilization of the health Centre. The descriptive survey research design was adopted for the study and a structured questionnaire containing twenty (20) items was used to collect data. The systematic random sampling technique was used. The population of the study was thirty nine thousand two hundred and forty three (39,243), representing full time undergraduates of the University of Benin with a sample size of one hundred and eighty two 182 undergraduates purposively selected from four faculties. The instrument was validated by two experts from the department

Musanga cecropioides R. Br. ex Tedlie (Family Urticaceae) is a tree distributed across some parts of Africa including Nigeria. Ethno-medicinal surveys shows that its leaves, root and root sap are used in the management of several health conditions, but there is a dearth of information on the biological activities of these parts of the plant to substantiate the ethno-medicinal claims. This study was aimed at evaluating the phyto-constituents and phytomedicinal properties of Musanga cecropioides leaf extracts, root extracts and root sap. The elucidation of phyto-constituents was done by carrying out qualitative and quantitative phytochemical screening, proximate analysis, and screenings for vitamins, carotene, amino acids and mineral elements using standard protocols. Acute and sub- acute toxicity assessments of the samples were carried out in experimental an mals using established protocols. Musanga cecropioides leaf extracts, root extracts and root sap were screened for antioxidant activities using 1,1-diphenyl-2-picryl hydrozyl (DPPH) and 2,2’-azinobis-3-ethylbenzothiozoline-6-sulfonic acid (ABTS) radical scavenging models, while the DNA protective effect was investigated on DNA damage caused by Fenton’s reagent. The antitussive activity was analyzed using the citric acid-induced cough model and mucus expectoration experiment, while anti- asthmatic properties were elucidated using the ovalbumin-induced asthma model. Antidiarrheal and anti-diabetic properties were elucidated using the castor oil-induced diarrhoea and Streptozotocin (STZ)-induced diabetes models respectively. The screening of Musanga cecropioides leaf extracts, root extracts and root sap for the phyto-constituents revealed the presence of alkaloids, tannins, saponins, flavonoids, moisture, fat, proteins, vitamins, carotene, essential and non-essential amino acids and micro and macro mineral elements in considerable quantities. The median lethal dose (LD50) for the aqueous and methanol leaf extracts, methanol root extract and crude root sap were indeterminable as no adverse effect was observed at the highest dose of 10000 mg/kg body weight, while the aqueous root extract caused absolute mortality at 5000, 7500 and 10000 mg/kg body weight leaving the LD50 at 2236 mg/kg body weight. The sub-acute toxicity study revealed that the extracts did not significantly alter the body weight and haematology parameters at 500, 1000, 2500 mg/kg. 1,1-diphenyl-2-picryl hydrozyl and 2,2’-azinobis-3- ethylbenzothiozoline-6-sulfonic acid scavenging assays revealed the presence of antioxidants in all samples with the leaf extracts showing the best activity. The leaf and root extracts protected pCAMBIA 1301 DNA from damage by Fenton’s reagent. Musanga cecropioides leaf extracts, root extracts and root sap showed significant anti-diarrhoeal activities, significantly increased mucus expectoration and suppressed cough bouts in guinea pigs at all doses in the antitussive study. In the anti-asthmatic study, the leaf extracts significantly increased the latency to pre-convulsive dyspnoea. The anti-diabetic study revealed significant reduction in glucose level by the aqueous leaf extract (50 mg/kg), methanol leaf extract (200 mg/kg), aqueous root extract (200mg/kg) and the root sap (2 ml/kg). Musanga cecropioides leaf, root and root sap possess antitussive, anti-asthmatic, anti-diarrheal and anti-diabetic activities. In conclusion, the therapeutic properties elicited by these plants extracts on selected diseases validated its ethnomedicinal reports.

Translation is the communication of the meaning of a source language text by means of an equivalent target language text. This study seeks to investigate the problems encountered by translators when carrying out a
translation exercise. Also, these problems outlined will be tackled using the techniques of translation. The data for this study were gotten from the Bible and grouped under the problems of translation they fall under; the techniques of translation were further used to solve the translation problems that were encountered. The data are analyzed using Uwajeh (2001), Four Models
Translation. The conclusion of the study is that languages are different in their structures, lexicons, etc. therefore, further studies should be made on the Uneme language by experts to develop the language

Methicillin-resistant Staphylococcus aureus (MRSA) is a well-recognized public health problem throughout the world. In this study presents data on the prevalence of MRSA and resistance pattern to other antibiotics on the selected specimen from three hospitals in Benin City, Edo State. A cross sectional study was conducted among 233 participants recruited from three hospitals in Benin City, Edo State they were 157 female and 76 male using a questionnaire and the following samples were collected from the participants such as nasal swab, urine and both nasal swab & urine. The culture media used are Nutrient and MacConkey agar . All media were prepared according to manufacturer’s instruction. The media used were sterilised in an Auto clave at 121 oC for 15 minutes.

Global statistics estimated that at the end of 2018, there were 9.3 billionmobilephone subscriptions, today virtually everyone has a cell phone. Shouldthesephones constitute a health hazard it would be a global pandemic. Soundispartof our daily life and sounds produced from phones are closest to us. This studywas undertaken to measure the frequency spectra of the sound producedbythree phones commonly used in Nigeria to determine if sound level exposuresfrom these phones should warrant the inclusion of a hearing protectionprogramme. Data was collected and evaluated to ascertain the impact of soundfrom three different types of phones: GSM mobile phone made by Nokia(Nokia1280), an android phone made by Infinix (Infinix Note 8) and an Iphonemadeby Apple (iPhone X), using a UT353 BT Mini Sound Meter (BluetoothVersion). The results showed that the total sound pressure levels for Nokia1280was 109.63dB and average of 98.83dB. This value exceeds the NIOSHallowable noise exposure levels of 85dB thus there is a cause for concerninusing Nokia 1280 to play music for a long time. While the total soundpressurelevels for Infinix Note 8 was 96.79dB which was slightly higher thantheNIOSH allowable noise exposure levels of 95dB for 1 hour but onaverageitwas found to be in line with the allowable noise exposure levels of 85dB. Asimilar lower sound level was observed in the Iphone X, an average of 77.25dBand a total of 88.05dB was recorded within an hour period. This is very safe according to the NIOSH Recommendations which stipulates that onlyover a4-hour period of continues sound can this value become a potential healthrisk. Itwas concluded that phones produced more recently takes into consideration the sound pressure levels and are current design following the NIOSHRecommendations, while older phone may pose a health risk as they hadhighervalues of sound pressure levels. It was therefore recommended that moreresearch need be carried out on the sound level measurement of different phonesas this will inform buyers and producers of these devices on thehealthramifications in using these phones.

Nigeria has no functional national policy on the care and welfare of older persons. Changing demographics in Nigeria, in addition to the breakdown of the family structure and absence of a social security system, present unique challenges to the elderly in Nigeria. This paper analyzes the current policy lacuna and future issues concerning older persons in Nigeria. It posits that the introduction of neoliberal economic policies created a vacuum in policy formulation and execution in which the older persons are not provided for within the social safety nets in the neoliberal state. This exploratory, qualitative study is based on interviews and
narratives of interviews with government officials. The findings of the study show that, in the face of rapid demographic change, one of the major challenges facing Nigeria is developing policies and appointing personnel capable of understanding and responding to the current social priorities and complex needs of an increasingly ageing population in the country. Furthermore, the findings of this study shows that modernization has brought a lot of changes in ageing population in Nigeria. The more modernized a society becomes the more the status of the other declines. The extended family no longer care for aged parents at home because of modernization. Based on the findings, the study provides recommendations that may assist the government to table policies that will promote the well-being of the elderly in Nigeria
