EVALUATION OF HYSTEROSALPINGOGRAPHY VERSUS LAPAROSCOPY IN THE DETERMINATION OF TUBAL FACTORS IN FEMALE INFERTILITY: A HOSPITAL BASED COMPARATIVE STUDY.
Authors: Choudhary Richa , Sinha Rishikant
Published: October 2020

Objectives: Hysterosalpingography and laparoscopy both are the diagnostic methods for assessment of female infertility.  The present study was to compare the evaluation of hysterosalpingography (HSG) versus laparoscopy in determination of tubal factors in female infertility.

Methods: Detailed assessment, physical examination and clinical investigations were performed in all 100 infertile female with age 20 years to 40 years. All patients were advised to perform digital HSG. Patients with an abnormal HSG underwent laparoscopy without delay, whereas in patients with a normal HSG, laparoscopy was performed three months after HSG. HSG is best scheduled during the 2nd -5th day interval immediately following the end of menstruation, to minimize risk for infection, avoid interference from intrauterine blood and clot, and to prevent any possibility that the procedure might be performed after conception.

Results: Data was analysed by using IBM SPSS version 23 software.  All data was tabulated and percentages were calculated. Mean ± standard deviation was observed.

Conclusions: Diagnostic laparoscopy is the gold standard in diagnosing tubal pathology and other intra-abdominal causes of infertility. Other hand, Hysterosalpingography is a frequently utilized diagnostic tool in the assessment of tubal status and detection of uterine anatomical defects in infertility. Hysterosalpingography and laparoscopy are not alternatives but complimentary investigations. But, inadequacy of hysterosalpingography (HSG) in determining the state of tubal patency, emphasizes the need for laparoscopy. Laparoscopy provides both a panoramic view of the pelvic reproductive anatomy and a magnified view of pelvic organs and peritoneal surfaces.

Adam as is the first prophet and man that God created on this earth. Before Adam was created, Allah SWT had hinted to the angels that he would make Adam the Caliph on this earth. That makes the angels ask questions to each other, especially the Devil who is one of the inhabitants of the sky who hears the word of God. The creation of Adam (as) did not make Satan happy, but he hated so much that he was finally expelled by God from heaven and threatened to tempt Adam and his grandchildren. This article contains the values ​​of character education that can be taken in the story of Adam and Satan, both from the very first time Adam was created until he was revealed to the earth, where all of the events of Adam were not escaped from Satan's observation.

PHOTOLUMINESCENCE OBSERVATIONS OF DONOR-ACCEPTOR EMISSION IN MILLED Cd0.3Zn0.7Se NANOCRYSTALS
Authors: Bagudo Ibrahim , Tanimu A.
Published: October 2020

Defects and impurities that arise during material synthesis are detrimental to device performance. Hence, an effective characterization tool is fundamental to effectively quantify and understand the origin of such defects. In this paper, we examine photoluminescence spectra (PL) from (650-900) nm of mechanically alloyed Cd0.3Zn0.7Se nanocrystals and observe three prominent emission peaks (1.4, 1.8, and 1.54) eV. The peaks were pinned at a fixed position despite a decrease in crystallites size which ought to increase the energy bandgap. The intensity of the peaks increases with milling time due to longer milling time which gives rise to a higher density of intrinsic defects. This was attributed to continuous deformations from the milling process. The formation energies of acceptor and donor defects remain constant to the conduction and valance band edge

Published: October 2020

The study involved the analysis of some selected heavy metals in drinking water consumed within Katsina Metropolis. The water samples were collected from Ajiwa dam raw water, taps, wells, boreholes, and sachet waters and the concentration of heavy metals (Cd, Pb, Cr, Co, and Ni), was determined using Atomic Absorption Spectrophotometer (AAS). The results obtained from the water analysis indicate that cadmium was not found in all the water samples. The concentrations range for lead were  (6.222-109.63)µg/L with maximum concentration value of 109.63 µg/L in Ajiwa dam raw water, above the World Health Organization (WHO) limit, nickel (0.72-6.99)µg/L with maximum concentration value of 6.99 µg/L in borehole water, within WHO limit, chromium (36-72)µg/L with maximum concentration value of 72 µg/L in well water, above WHO limit, cobalt  (4.758-9.516) µg/L with maximum concentration value of 9.516 µg/L in well water, within WHO limit. The results indicate that most of the concentrations of the heavy metals determined were within the WHO limit, except for chromium in well water which may arises from the Government activities of money recycling and incineration of old bank notes which does not affect other water sources in the area and lead in Ajiwa dam raw water which was further removed through water treatment processes. Moreover, the Analysis of Variance  (ANOVA)  indicate no significant difference in the means of the heavy metals concentrations in all the water samples analyzed, and this may be due to the same physicochemical factors and limited industrial activities in the study area

Published: October 2020

Analysis of prevalence and risk factors for Human Papilloma Virus (HPV) is the basis for prophylactic strategies against HPV infections. This study was to determine the seroprevalence of human papillomavirus, sociodemographic and risk factors associated with acquiring the virus among the study population. A total of 195 samples were collected by simple random sampling technique from three major hospitals in the zone. Serum from blood samples was used for ELISA and analyzed for IgM. Overall prevalence of 3.08% (6/195) was established for HPV infection. Patients with early sexual activity and those with multiple sexual partners were likely to be infected than their counterparts with 15.8%: 3/19 (χ 2 =16.4, df=3, p=0.001) and 50%: 2/4 (χ 2 =30.2, df=1, p=0.005) respectively. The infection was more among those who got married at age range of 26-30 years with prevalence of 5.4%: 2/37 (χ 2 =1.30, df = 5, p=0.82). On the basis of sex, female were found to have higher prevalence of 3.6%: 6/167(χ 2 =1.04, df = 1, p=0.6). Subjects with sexually transmitted disease (STD) had a higher prevalence of 8%: 2/25(χ 2 =2.45, df=2, p=0.32). The study shows that infection with HPV was strongly associated with age of sexual debut and number of sexual partners. It also reveals the occurrence of HPV infection in Kogi East, Nigeria. Hence, there is need for routine screening, public education and vaccination to prevent the spread of the virus which is a threat to public health.
APPLICATION OF MACHINE LEARNING TECHNIQUE FOR THE PREDICTION OF NEONATAL MORTALITY USING MULTIPLE RISK FACTORS
Authors: Odion P. O. , Musa M. N. , Suleiman Tasiu , Isa M. M.
Published: October 2020

It is a common knowledge that one of the major cause of neonatal mortality is high-risk birth, which can be identified through risk factors. Though, there are many risk factors associated with neonatal mortality (i.eshort birth interval, pre-natal care etc), most interventions of government and other agencies target birth based on a single risk factor (i.e. poverty) even though most neonatal deaths are not from the targeted risk factor,thus, failing to curb the prevalence of early-life mortality. Hence, data from Nigerian Demographic and health Survey was gotten for this study and nine risk factors were used to predict neonatal mortality risk by applying Support Vector Machine algorithm to build a predictive model. KMeansSMOTE was used to solve the problem of class imbalance in the dataset, while model hyper-parameter tuning was appliedto the SVM model to get a better prediction. Neonatal mortality risk was estimated as a function of nine risk factors.  Risk factors chosen for the study were compared with four (4) risk factors from a previous study. The result gave a sensitivity of 78%, specificity of 44% and area under curve of 60% compared to using only four risk factors which has a sensitivity of 63%, specificity of 37% and area under curve of 50%. The result shows that having more risk factorsgives a considerable improvement by predicting more neonatal deaths.This will aid researchers and governments to identify more risk factorscausing neonatal deaths especially in Africa

Published: October 2020

The use of information communication Technology (ICT) has grown exponentially that its monumental application can be seen in almost every aspect of human endeavor of which agriculture is not an exception to the profound benefits provided by this field. Groundnut is used to be one of the most remunerative farming enterprises in Nigeria prior to the discovery of crude oil. In Nigeria groundnut is crushed to produce roasted snacks, groundnut oil or boiled either in the shell or unshelled for direct consumption. This research work aims at mitigating the difficulty associated with manual detection of groundnut maturity using certain features of the leaves. Customary, to examine the maturity of groundnut it requires constant monitoring and observation of changes in the color of groundnut leaves from purely green to purely yellow. This method of maturity assessment in order to harvest the crop without excessive loss is less accurate and consumes an awful lot of time particularly in a large farm. Hence, this approach cannot be fully reliable as color is subjective to our naked eyes and failure to harvest the crop when it reaches optimum maturity stage might cause the seeds pod to decay/ germinate underground due to moisture which might eventually result in quantity reduction of the expected yield. Consequently, design of an automated system is pivotal to farming and becomes necessary in the context of ICT era. This task is achieved by identifying the stages of the leaves of the groundnut plant using a convolutional neural network classifier. An

Published: October 2020

The oligodynamic hold of gold and silver is extant and extremely relevant as a proactive measure against infections. The antimicrobial effect of gold and silver jewelries was determined on skin bacteria by introducing them into culture plates already inoculated with bacterial isolates; Staphylococcus aureus, Staphylococcus epidermidis and Pseudomonas aeruginosa from the wrist, neck and ear regions of the skin. Samples were collected by swab sampling and isolates were identified by their cultural morphology and biochemical characterization. Results showed that both precious metals were able to inhibit all three bacteria with silver jewelries giving wider zones of inhibition measuring between 3 mm to 7 mm while gold jewelries gave zones of inhibition between 1 mm to 4 mm. The culture plates containing Pseudomonas aeruginosa recorded the highest zone of inhibition while the least was observed in the culture plates that contained Staphylococcus epidermidis. No zone of inhibition was observed with ordinary golden-coloured and silver-coloured jewelries which served as negative control. This study showed that gold and silver are oligodynamic with silver having a higher oligodynamic efficacy on the skin bacteria tested

Published: October 2020

Multidrug resistance (MDR) exhibited by some strains of Escherichia coli may be due to acquiring mobile genetic element (R-plasmid) by the bacteria, or intrinsically induced by inappropriate use of antibiotics by the hosts.  Infection by such strains may result to prolonged illness and greater risk of death. The study evaluated the impact of curing on antibiotic resistance on selected clinical isolates of E. coli. Twenty clinical isolates of E. coli from our previous studies were re-characterized using conventional microbiological techniques. Antibiotic sensitivity testing was determined by disk diffusion method, MDR selected based on resistance to ≥ 2 classes of antibiotics. Multiple antibiotic resistance (MAR) index was determined as ratio of the number of antibiotic resisted to the total number of antibiotics tested and considered significant if ≥. 0.2. The isolates that showed significant MAR index were subjected to plasmid curing using acridine orange, thereafter, profiled for plasmid and the cured ones were re-tested against the antibiotics they initially resisted. Out of the 20 isolates, 19 (95%) were confirmed as E. coli, all (100%) of which were MDRs, which was highest against augmentin (78.9%) followed by amoxacillin (52.6%). However, after the plasmid curing only 6 (31.6%) out of the 19 isolates cured retained significant MAR index and the level of the significance had reduced drastically in 16 (84.2%) isolates. Conclusively, curing assay can completely eliminate R-plasmid acquired resistance. More studied on plasmid curing agents for possible augmentation of the agents into antibiotics may see the rise of successful antibiotic era again.

Nematode pests contribute significantly to poor growth and losses in ornamental plants. However, majority of ornamental garden operators have little or no knowledge of these nematode pests. This study assesses the perception of horticulturists on plant-parasitic nematodes (PPNs) of ornamental plants in Port Harcourt metropolis. A total of 23 ornamental gardens were randomly chosen and visited. Structured questionnaire was randomly administered directly to all operators in collection of data and options were given in code to rank the results. A total of fifty-three soil samples were collected from all the gardens visited. Nematode pests were extracted from the samples using standard procedures. Data were processed using descriptive statistics, diversity indices, relative importance value (RIV) and analysis of variance. The results showed that 95.7% of the horticulturists were male, 78.2% were youth, while 100.0% of the ornamental garden owners had no knowledge of nematode pests attacking ornamental plants. Four nematode pest genera, Meloidogyne, Pratylenchus, Tylenchulus and Helicotylenchus were found in the soil being used for propagation by these horticulturists. However, Meloidogyne species with the RIV of 40.45% were the most important genus and the most frequently encountered nematode pest (relative frequency of occurrence of 19.35%). Hilltop horticultural garden had the highest mean population of PPNs, but not significantly more than PPNs in other gardens. The study revealed that nematode pests are one of the major bio constraints to ornamental plants and that soil if not treated could be a primary source of nematode infection.
EFFECTS OF CALCIUM HYDROGEN PHOSPHATE ON LEAD UPTAKE BY COWPEA (VIGNA UNGUICULATA)
Authors: Dagari M. S. , Musa Mohammed Salisu
Published: October 2020

The effects of calcium hydrogen phosphate on lead (Pb) uptake by cowpea (Vigna unguiculata) were investigated in a growth chamber experiment coupled with atomic absorption spectrophotometry (AAS) and colorimetry analyses. Cowpea seeds were planted and harvested in soil samples treated with Pb+2 added as lead nitrate at the rates of 0, 1000 and 3000 mg/kg followed by calcium hydrogen phosphate (CaHPO4) at 0, 10, 50 and 250 mg/kg. Increases in shoot yield brought about by phosphate fertilization were observed to oppress the shoot lead concentration as a result of growth dilution, where the actual amount of lead in shoots was unaffected by phosphate treatment. This work revealed that there is no substantial effect on lead uptake by cowpea, as a result of phosphate fertilization. Therefore, phosphate fertilization is a good means of cowpea production with minimal lead uptake and hence safe for human consumption

In spite of the economic importance of plant-parasitic nematodes reported on ginger, little or no information is available as regards plant-parasitic nematodes diversity and abundance on ginger in Nigeria. This work was conducted in 2018 to identify plant-parasitic nematodes associated with ginger in Kaduna state and to determine their population densities. Three Local Government Areas (LGA) were visited and between 12 to 16 ginger farms were sampled per LGA. A total of 42 soil samples was collected at a depth of 0 - 30 cm of the plant rhizosphere. Plant-parasitic nematodes were extracted from the soil using modified sieving and decanting method. Identification to genera level was done using identification keys viewing with dissecting microscope at X40 magnification. Nineteen (19) genera of plant-parasitic nematodes were identified, with 12 genera occurring in all LGA(s). Scutellonema (113.33), Meloidogyne (110), and Pratylenchus (93.33) were the most abundant per 100 ml of soil when locations are combined. Plant-parasitic nematodes population average was 870-950 per 100 ml of soil. All locations showed a high percentage similarity of plant-parasitic nematodes diversity and were statistically similar. This high diversity and population abundance can be among the reasons for the low productivity of ginger in Nigeria. It is therefore important to educate farmers on the economic importance of plant-parasitic nematodes on ginger and its management. Further research using the most occurring genera to establish the threshold population densities capable of causing economic yield loss needs to be conducted

The present investigation involves Taguchi Grey relational analysis-based optimization of transesterification process parameters such as methanol to oil molar ration, catalyst loading and  temperature and their effect on both per cent fatty acid methyl ester (FAME) yield and heat transfer coefficient (HTC) of transesterified cotton seed oil (TC). A Taguchi L9 orthogonal array was designed and nine experimental runs were conducted based on the designed experiments. The FAME (ester) yield and HTC were recorded for each experiment. Based on the average responses computed from Taguchi grey relational analysis, methanol to oil molar ration of 9:1 (32.6 wt% of methanol), catalyst loading of 0.5 wt% and temperature of 60 oC were identified  to be the optimal parameters. Confirmation test conducted using the optimal parameters setting demonstrated an improvement of 0.3% in grey relational grade. Methyl ester group was detected in TC on 1438.8 cm-1 by FTIR spectra. Cooling curve analysis of the TC from the confirmation experiment indicated outstanding quenching performance compared to raw cotton seed oil (FC) and SAE40.

This study is aimed at examining the spatial distribution and locational implications of public conveniences in Kano metropolis. This research utilized mixed methods; where both qualitative and quantitative methods were used. Both primary and secondary source of data were used in this study. The primary data were obtained from field measurementsile the secondary data were obtained from the Kano State Ministry of Environment, Kano State Urban Planning Development Authority (KNUPDA) as well as journals and previous theses. Materials used for this study include: Geo-positioning system (GPS) device (Garmin cx76 model) used for taking coordinates of the public conveniences (PCs). Computer software (Arc GIS 10.3) was also used in processing and analyzing of data generated from field. Availability sampling was used in administering questionnaires while purposive sampling was used for interview. The study find out that PCs are built rampantly without approval from appropriate government authoritymake them to build without complying with the standard rules and regulations. It is found that the distribution pattern of public PCs in Kano metropolis is mostly nucleated as they depend categorically on commercial activities as most of them are in motor parks or markets. This result also indicates that there is presence of air pollution and unsanitary condition due to poor drainage.

The study analyzed the supply sources and catchment areas of Wudil cattle market in Kano State. The objectives focused on types of cattle traded, supply source locations of cattle and catchment areas of buyers. Data were collected on types of cattle, sources of their supply and catchment areas of buyers using records of cattle observation and Focus Group Discussion with nine participants including the market leaders and other traders. Types of cattle were presented in table. Sources of supply of cattle and catchment areas for the market were depicted on maps using ARCGIS software. Based on colour of skin and castration, the major types of cattle supplied into the market are Baki (Ambala), Fari (Bunaji or White Fulani), Ja (Rahaji or Red Bororo), Galare (White-horned), Shodare (breed of white and red species), Nordi (breed of white and black species) and Bartandi (castrated). Cattle are supplied from three main sources: other countries (Niger Republic and Cameroun), other states in Nigeria (Taraba, Adamawa, Jigawa and Yobe) and within Kano State. The catchment areas are three: primary catchment area consisting of buyers within Kano State and neighbouring states, secondary catchment area including buyers largely from northeast (Gombe and Yobe States) and middle belt of Nigeria and tertiary catchment area consisting of all the states in the southern parts of the country. Recommendations given included development of market and transport infrastructure and further study on cattle transport and buyer characteristics

In this study 10 soil and 11 ground water samples were randomly collected, and the 222Rn concentrations were measured using a DURRIDGE RAD7 electronic radon detector. The radon concentration in ground water ranged from 0.53 BqL-1 to 5.13 BqL-1 with a mean value 2.37 BqL-1. The results show that all the groundwater samples collected have 222Rn concentrations below the US EPA Maximum Contaminant Level (MCL) of 11.1 BqL–1 (for states without radon monitoring policy and enhanced indoor air programs). All the ground water samples also have 222Rn concentrations below MCL of 100 BqL–1 recommended by EU. The annual effective dose due to ingestion (Hing) of 222Rn in the groundwater ranged from 0.00386 – 0.03744 mSvyear-1 with a mean value of 0.01706 mSvyear-1. These values are within the ICRP recommended reference level of 1 mSvy–1 for the intake of the radionuclide in water by the general public for a prolonged exposure. The effective radium content, radon mass exhalation rate and alpha index of the soil samples varied from 0.574 – 1.170 Bqkg-1, 0.104 Bqkg-1d-1 – 0,212 Bqkg-1d-1 and 0.00287 – 0.00585 respectively. The alpha index suggests that none of the selected soil samples have a radon mass exhalation that could cause indoor radon concentrations exceeding 200 Bqkg-1. Therefore, it is concluded that the radon concentration in ground water and soil in the study area indicate that the ground water is safe for drinking and it is safe to use the soil as a building material.

The harmful effects of spent engine oil on aquatic and terrestrial ecosystems have been well established in literature. This study was conducted to assess the bio stimulatory influence of amendments; compost and inorganic fertilizer on bacterial degradation of spent engine oil contaminated soil.  500 g of unpolluted soil was collected and artificially contaminated with 5, 10 and 15% (v/w) spent engine oil. The experiment was laid out in a completely randomized design. Each amendment (50 g) was subsequently mixed thoroughly with the spent engine oil contaminated soil at varying levels except nine experimental bottles used as control. Incubation study was carried out and lasted for four weeks. Estimation of total petroleum hydrocarbon, pH, electrical conductivity, temperature and bacterial population density was done within two weeks interval during the incubation study. Results obtained indicate that compost significantly enhanced total petroleum hydrocarbon reduction by 87% while inorganic fertilizer facilitated 62% total petroleum hydrocarbon reduction on 5% spent engine oil contamination level respectively. Estimation of hydrocarbon utilizing bacteria on 5, 10 and 15% spent engine oil contaminated soil indicated that compost enhanced higher hydrocarbon utilizing bacteria thereby influencing bacterial degradation than those stimulated with inorganic fertilizer. pH remained in the range of alkalinity (7.8 and 8.06) for compost and 6.2 and 6.7 for inorganic fertilizer. The potential that compost recorded in influencing bacterial degradation of spent engine oil contaminated soil in this study has made it a good bio stimulant for the bioremediation of hydrocarbon polluted environments.

The sources of energy we use in our day-day activities contributes significantly to the alarming global warming which the world is currently experiencing. A technical solution to the menace of an environmental friendly, sustainable and reliable energy is the peak of this research. Wind speed data from 2014 to 2017 measured at a height of 2 m were analyzed using the Weibull’s distribution method. The results show that all through the studied years and seasons, the mean wind speed distribution for the rainy season is significantly stable as seen from the K-values. However, the dry season has the highest K-value of 2.08 signifying more stable winds during the season. The monthly averages, computed for height of 60 m above ground level ranges between 2.15 m/s and 6.42 m/s with the maximum wind speed in June while the minimum wind speed occurred in September. This implies that the wind velocity of the study area tends to be lower during the end of the rainy season. Nevertheless, the deviation in the mean wind speed was not significant, as such wind energy can serve as a reliable energy source for the area hence could be harvested

O objetivo da pesquisa foi conhecer o perfil das vítimas de traumatismo cranioencefálico atendidas em um pronto socorro do sul do Brasil. Trata-se de um estudo quantitativo, com caráter retrospectivo, descritivo e transversal realizado por meio de fichas de atendimento de pacientes que deram entrada no serviço, por esse trauma, em 2018. Dos 711 pacientes, 63,2% era do sexo masculino, na faixa etária de 0 a 12 anos (38,7%), a maioria residente na cidade de Pelotas (78,8%), sendo o turno da noite, o que mais registrou casos (43,7%). Quanto à gravidade, o TCE leve predominou (53,6%). Neste estudo, ganharam destaque as quedas, representando 53,7% dos casos, seguido pelos acidentes de trânsito, com 24,6%. Entende-se que o TCE atinge, com maior frequência, as crianças, em virtude do supervisionamento ineficaz, reforçando a necessidade de mais pesquisas acerca do assunto.
