Primary data was obtained aided by a hand-held radiation meter and a well-structured questionnaire. With the aim of ascertaining the radiation distribution pattern and occurrence rate of Electro Hypersensitivity Syndrome’ (EHS) in the study area. The analysis of variance test ‘ANOVA’, an inferential statistics was used to ascertain the radiation distribution pattern, while the descriptive statistics was used in determining the occurrence rate of (EHS) inpopulations of the study area. A convenience sampling technique was adopted, and 30 sampling unit of residential apartment were chosen for the study, relying on homogeneity, inclusion and exclusion criteria. The pre-tested questionnaire scored 74% Cronbach's Alfa reliability. Findings from the study revealed that total indoor radiation varied significantly across the study area, with F(2,27) = 38.599, P < 0.00, at (α = 0.05). The occurrence rate of the understudied EHS illnesses were determined to be in the following order: sleep disorder, fatigues, headaches, dizziness, loss of appetite and memory loss, with mean averages of 3.53,3.26, 2.97, 2.70, 2.17, and 2.03 respectively. Hence a recommendation for public sensitization on the occurrence, effect and necessary policy control measures, towards minimising public exposure to indoor non-ionising radiation, by relevant stakeholders such as: the Standards Organisation of Nigeria, Federal and States Ministries of Environment and the Nigerian Customs was necessitated.","PeriodicalId":292938,"journal":{"name":"BIMA JOURNAL OF SCIENCE AND TECHNOLOGY (2536-6041)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127973298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work was carried out to ascertain the indoor and outdoor background ionizing radiation in Gombe state as a precautionary measure due to recent development of radioactive activities in the State. RDS-31 Survey meter placed 1m above the earth surface was used for taking readings. The measured average exposure rates ranged from 0.007 to 0.017 mR/h for indoor and 0.007 to 0.015 mR/h for outdoor with a total mean of 0.010 ± 0.003 mR/h, which are within the limit of world average of 0.013 mR/h. The indoor absorbed dose rate ranged from 61.34 ± 7.52 nGy/h in Kwami to 149.21 ± 57.35 nGy/h in Billiri with a total mean value of 88.47 ± 32.64 nGy/h, which is higher than World’s average of 84.00 nGy/h, while the outdoor ranged from 61.34 ± 17.45 nGy/h in Shongom to 134.42 ± 38.61 nGy/h in Kaltungo with a mean total value of 90.24 ± 29.88 nGy/h, which is 31.24 nGy/h higher than the standard average of 59.00 nGy/h. Equivalent dose rate was calculated to be in the range of 0.59 ± 0.07 mSv/yr to 1.44 ± 0.55 mSv/yr with a total mean of 0.86 ± 0.32 mSv/yr, which is within the International Commission on Radiological Protection(ICRP)recommended limit of 1 mSv/yr. The AEDE shows a range of 0.33 ± 0.08 to 0.73 ± 0.28 mSv/yr for indoor and 0.08 ± 0.02 to 0.16 ± 0.05 mSv/y for the outdoor respectively. The sum is found to be 0.54 mSv/yr which is 0.02 mSv/yr higher than the world’s average of 0.52 mSv/yr. Estimated life-time cancer risk ranges from 1.20 x 10-3 to 2.56 x 10-3 mSv/yr, while outdoor ranges from 0.30 x 10-3 to 0.58 x 10-3mSv/yr with a total mean of 2.08 x 10-3 mSv/yr which is larger compared with the resulting worldwide average of 1.45 x 10-3. The excess lifetime cancer risk values indicated that the probabilities of contracting cancer for residents of Gombe, Kwami, Dukku, Yamaltu Deba, Bajoga, Shongom, Balanga, Funakaye, Kaltungo are low but higher in Billiri, and Akko (Mai-Ganga). These values may not constitute any immediate health risk to the residents of Gombe state but precaution should be taken in order to avoid stochastic effect.","PeriodicalId":292938,"journal":{"name":"BIMA JOURNAL OF SCIENCE AND TECHNOLOGY (2536-6041)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116511356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients’ data including socio-demographic characteristics, cardiovascular risk factors, medication history and clinical characteristics were retrieved. The data were presented as proportions and percentages in tables and pie chart formats. The analysis was done using statistical package for social sciences (SPSS) version 21.0. Of the 807 case folders that were reviewed, 64.5% were female patients, with majority (61.3%) below 50 yearsof age and 90.2% were married. Over 50% had secondary/primary education and most (57.9%) were unskilled labourers. About one-third (34.6%) were engaged in moderate to regular physical activities. The prevalence of hypertension, dyslipidaemia and obesity was 84.8%, 5.1% and 47.1% respectively. More than three quarters of the patients (87%) were on multiple oralantidiabetic agents and metformin was the most prescribed medication (93.8%). The antihypertensive agents with the highest prescription rate was lisinopril (57.9%), while 50.9%, 6.5%, and 2.7% received low dose acetylsalicylic acid, lipid lowering agents and pregabalin respectively. Hypertension was the most prevalent cardiovascular risk factor in the study population, followed by overweight/obesity.

The study area lies between longitudes 5030' – 7000' E and latitudes 9030' – 10030' N. To achieve this objective, high resolution aeromagnetic data covering the study area was subjected to magnetic residual separation and analytical signal using Oasis Montaj version 8.4. The Land satellite imagery data was also subjected to false colour composite analysis using ILWISversion 3.3 software. Combination of this analysis aided in mapping of lineaments within the study area. Result of lineaments mapping from analytical signal and land satellite images shows high density lineaments around Wushishi, Zungeru, Tegina Kagara, Pandogari, Alawa, Gurmana and low density lineaments around Bobi, Kuta, Guni, Minna, Tenenge. These lineaments having a dominant trend in the NE-SW and NW-SE, E-W minor directions were interpreted as joints, veins, faults, foliations and lineation of outcrops. Field studies in Tegina, Zungeru and Wushishi falling within areas with high lineament density revealed good groundwater yield from motorized pumps, hand pumps and hand dug wells. This is contrary to what was observed in Gidan Gwari an area attributed to low lineament density where only one hand bore hole out of the seven drilled boreholes was productive.","PeriodicalId":292938,"journal":{"name":"BIMA JOURNAL OF SCIENCE AND TECHNOLOGY (2536-6041)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133641399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The existing method of severity classification for SCA patient is done manually through a microscope which is time-consuming, tedious, prone to error, and require a trained hematologist. The affected patient has many cell shapes that show important biomechanical characteristics of patient severity level. The main purpose of the study is to develop an automated severity level classification method of SCA patients by comparing deep learning AlexNet and Support Vector Machine (SVM) to enable present the percentage of each cell present in blood smear image. Hence, having an effective way of classifying the abnormalities present in the SCA disease based on the level of patient severity to give a better insight into managing the concerned patient's life. The study was performed with 182 SCA patients (over 11,000 single RBC images) with 14 classes of abnormalities and a class of normal cells to develop a shape factor quantification and general multiscale shape analysis to classify the patient based on severity level. As a result, it was found that the proposed framework can detect 85.4% abnormalities in SCA patient blood smear in automated manner when compared with Support Vector Machine (SVM) method with 71.9%.

Various types of bacteria/viruses are categorized as pathogens, disease causing organisms that can be found in pretreated or inadequately treated water. Water, being dynamic, needs to be constantly analyzed to minimize contaminants that could be detrimental to the consumers. E. coli and fecal coliform are bacteria whose presence can indicate water contaminated by human or animal wastes, causing short-term health effects. When there is seepage of contaminant through well casing, cracks or holes in the well casing allow water that has not been filtered through the soil to enter the well. This seepage is common in the wells made of concrete, clay tile, or brick. These are the nature of wells commonly found across the study areas. Most of the bole holes are hand dug, shallow, located close to river banks where refuse and farming activities characterized by bush burning, application of fertilizers, animals and human defecation is the order day due to these reasons, water sources across the study areas are vulnerable to different kinds of contamination. Investigation into water quality is not a relatively new phenomenon but literature concerning the quality of drinking water from the study is sparse. 62 water Samples were collected at random from both well and boreholes at different location within the study areas using containers with earlier prepared nutrient broth. Three different media were prepared adhering strictly to the media manufacturer’s instruction. For the determination of E. coli, 24g of EMB was used and SS agar was used for Salmonella species. Results shows that in well water during rainy season the mean concentration of salmonella spp. ranged from (153– 272 CFU/ml), Total coliforms, well water during rainy season mean concentration ranged from (418 – 624 CFU/ml), During dry season, values ranged from (81 – 126 CFU/ml), while for E.coli, in well water during rainy season, the mean values ranged from (33 – 71 CFU/ml),.

This study investigates the chemical constituents and larvicidal activity of volatile oil obtained from Solenostemon monostachyusagainst the larvae of Anopheles gambiae. The volatile oils were extracted using hydro-distillation in a Clevenger type apparatus and analyzed using GC-MS. The larvicidal assay was carried out against Anopheles gambiae larvae at concentration range of 12.5- 400 μg/mL. The analysis of the volatile oil showed that the major constituents of the oil were Caryophyllene oxide (21.6%), β-Caryophyllene (19.6%), β-Pinene (9.8%) and Germacrene D (7.3%). Results showed that larval mortality increases with increasing exposure period to the volatile oils from S. monostachyus. The larvicidal activity demonstrated that the mosquito larvae were susceptible to the volatile oil with LC50 of 23.44 μg/mL. The results suggest that S. monostachyus essential oil has potentials for the control of Anopheles gambiae.
