    This paper examines the concept of indexing and abstracting, where index is define as systematic arrangement of entries designed to enable users to locate information in a document. While abstract at the other hand is an intellectual summary of an information package. The paper tried to finds out the availability and use of indexes and abstracts in Nuhu Bamalli Polytechnic Library (Annex) Zaria. The paper finds out that most types of indexes and abstracts are available and mostly used by Academic staffs and Students. It concludes that subject and citation indexes, as well as subject abstract were the most highly used by the respondents in the library; this could be due to lack of awareness about the other existing types of indexes and abstracts. However, some recommendations were made which includes; public awareness to the staffs and Students about the other existing types of indexes and abstracts and also more experts should be employed because as at present only one person is in charge of Indexing and Abstracting services.

    Employing Informetric analysis, the study investigated the features, types of documents, subjects spread and challenges affecting the growth and development of Ahmadu Bello University, Zaria Institutional Digital Repositories (ABU-IDR). The findings of the study indicated that the IDR has diverse features, deploying DSpace, Dublin core metadata elements and Open Archive Initiative – Metadata Harvesting Protocol (OAI-PMH) to make the repository robust and interoperable. As reported by earlier studies, ABU-IDR is also found to be dominated by theses and dissertations with 9,857(95.82) documents. Finding on subjects spread of theses and dissertations illustrated that Faculties of Sciences and Education have the largest subject coverage with 1979 (20.1%) and 1702 (17.3%) respectively. With diverse features and deploying DSpace, OAI-PMH and its interoperability, the study concluded that ABU-IDR has gained considerable traction in recent years. However, the IDR can be made more effective and efficient by creating institutional repository policy that will take care of copyright, deposition right, diversification of contents and advocacy which are the major challenges hampering the growth and development of the IDR

    In this paper, a graphical user interface (GUI) for position and trajectory tracking of the ball and plate system (BPS) control scheme using the double feedback loop structure i.e. a loop within a loop is proposed. The inner and the outer loop was designed using linear algebraic method by solving a set of Diophantine equations and  sensitivity function. The results were simulated in MATLAB 2018a, and the trajectory tracking was displayed on a GUI, which showed that the plate was able to be stabilized at a time of 0.3546 seconds, and also the ball settled at 1.7087 seconds, when a sinusoidal circular reference trajectory of radius 0.4m with an angular frequency of 1.57rad/sec was applied to the BPS, the trajectory tracking error was 0.0095m.  This shows that the controllers possess the following properties for the BPS, which are; good adaptability, strong robustness and a high control performance.

    Democracy and unemployment among youth are two antithetical bed-fellows. Unemployment hinders the progress and development of democracy in any country, be it developed or a developing one. The young, vibrant and energetic are important resources that should not be left idle for a democratic experiment to thrive. Thus, the youth have been the bane of Nigeria’s democracy since inception in 1999. Hence, becomes a cog in the wheel of democratic processes where it manifests itself in a myriads of serious socio-economic and political crises such as pipeline vandalism, political thuggery, kidnappings, prostitution and insurgency to mention a few. It is against this background that, this paper attempts to look at youth unemployment in relation to Nigeria’s democracy by using conflict theory as a basis for explanation. However, it is suggested that reducing youth unemployment is critical to the growth and development of Nigeria’s democracy as well as its stability

    Rice husk ash (RHA) and palm oil fuel ash (POFA) is a by-product from agricultural waste produced thousand tonnes every year. This paper presents the use of RHA and POFA as a substitute material for quartz in fabricating an improved porcelain ceramic. The RH was thoroughly washed with distilled water in order to remove adhering soil and dust. After that it was dried in an oven at 100 ºC for 24 hours. Then the dried husk was subjected to the chemical treatment; 2M HCL, 5% solid at 25 ºC before calcinations to increase silica content. Untreated POFA was dried in an oven at 100 ºC for 24 h. It was ground in a ball mill for 1.5 h with the revolution rate of 200 rev/min to reduce the particle size. Untreated POFA was sieved to remove the particles coarser than 50 μm. The POFA was treated by heating it at a temperature of 600 ºC for 1.5 h. The mixed powder was then pressed into pellets at mould pressure (MP) 91 MPa. All the pellets were sintered at the temperature of 1100 ºC for 1 h hour, 2 h hour s and 3 h hours soaking times. It was found that the highest compressive strength occurred at 20 wt% RHA and POFA and a soaking time of 2 h. The increment in the strength could be attributed to the changes in the increase in mullite and critobalite

    Urinary tract infection caused by bacteria leads to inflammation and over growth of uropathogens and prevalence of infection for both genders, but women is more vulnerable especially at the sexually active ages. But unfortunately, the continuous emergence of antibiotic resistant bacterial strains brings most serious public health concerns. It is therefore, important to look for more alternative, effective, safer and safer treatments. The aim of the present study was to investigate antimicrobial activity of Securidaca longipedunculata root extracts against some human pathogenic bacteria and fungi using agar well diffusion method and agar dilution for minimum inhibitory concentration (MIC). Phytochemical and acute toxicity studies were carried out using the standard methods. Phytochemicals which include alkaloids, flavonoids, saponins, tannins, carbohydrates and triterpenes were detected in both aqueous and methanolic extracts. The antimicrobial results revealed that, the methanolic extract had promising antibacterial activity. For intense Escherichia coli was found to be the most susceptible bacteria in both methanol and aqueous extracts at 500mg/ml with inhibition zones of 20 mm and 16mm, Staphylococcus aureus was next most susceptible bacteria to methanol extract of the root with inhibition zone of 16 mm and MIC of 31.25 mg/ml respectively. The extracts does not showed activity against all the tested fungal isolates at lowest concentration 62.5 mg/ml. The LD50 of Securidaca longipedunculata was found to be greater than 5000 mg /kg and could be considered safe for consumption

    Molecular Detection of Influenza A(H1N1)Pdm09 Virus Among Chronic Kidney Disease Patients: A Peripheral Blood Sample Approach and Assessment of the Associated Risk Factors

    Get PDF
    Introduction: Chronic kidney disease (CKD) is a progressive loss of functional nephron characterized by various risk factors. Influenza virus has been found to cause rhabdomyolysis, which is toxic to the kidneys and can initiate or worsen CKD. This study aims to investigate the frequency and molecular detection of Influenza A(H1N1)Pdm09 Virus gene among CKD patients attending University of Maiduguri Teaching Hospital, Nigeria.Materials and Methods: Peripheral blood samples were collected from 150 CKD patients. One-step RT-PCR was performed for detection of influenza virus using the Centers for Disease Control and Prevention protocol. Relevant clinical data were collected in standardized questionnaires from each patient, and medical history was obtained from their hospital records.Results: Conventional PCR analysis revealed that 16% of the CKD patients tested positive for Inf A/Pdm H1N1. The virus frequency was found to be higher among patients in CKD stage 5 (end-stage CKD) and lower in CKD stage 3 (moderate CKD). Additionally, female CKD patients and those in the age group of 55-64 years showed a higher susceptibility to Inf A/Pdm H1N1 infection.Discussion: The study provides evidence of the presence of Inf A/Pdm H1N1 in CKD patients, aligning with previous research showing its involvement in kidney disease aggravation. CKD patients often exhibit immune dysregulation, which might facilitate the virus's invasion and persistence. Conclusion: This study provides evidence of an association between Influenza A(H1N1)Pdm09 viraemia and decreased kidney function among CKD patients. The findings highlight the importance of monitoring and preventing influenza infection in CKD patients to prevent further kidney damage

    Global, regional, and national under-5 mortality, adult mortality, age-specific mortality, and life expectancy, 1970–2016: a systematic analysis for the Global Burden of Disease Study 2016

    BACKGROUND: Detailed assessments of mortality patterns, particularly age-specific mortality, represent a crucial input that enables health systems to target interventions to specific populations. Understanding how all-cause mortality has changed with respect to development status can identify exemplars for best practice. To accomplish this, the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) estimated age-specific and sex-specific all-cause mortality between 1970 and 2016 for 195 countries and territories and at the subnational level for the five countries with a population greater than 200 million in 2016. METHODS: We have evaluated how well civil registration systems captured deaths using a set of demographic methods called death distribution methods for adults and from consideration of survey and census data for children younger than 5 years. We generated an overall assessment of completeness of registration of deaths by dividing registered deaths in each location-year by our estimate of all-age deaths generated from our overall estimation process. For 163 locations, including subnational units in countries with a population greater than 200 million with complete vital registration (VR) systems, our estimates were largely driven by the observed data, with corrections for small fluctuations in numbers and estimation for recent years where there were lags in data reporting (lags were variable by location, generally between 1 year and 6 years). For other locations, we took advantage of different data sources available to measure under-5 mortality rates (U5MR) using complete birth histories, summary birth histories, and incomplete VR with adjustments; we measured adult mortality rate (the probability of death in individuals aged 15-60 years) using adjusted incomplete VR, sibling histories, and household death recall. We used the U5MR and adult mortality rate, together with crude death rate due to HIV in the GBD model life table system, to estimate age-specific and sex-specific death rates for each location-year. Using various international databases, we identified fatal discontinuities, which we defined as increases in the death rate of more than one death per million, resulting from conflict and terrorism, natural disasters, major transport or technological accidents, and a subset of epidemic infectious diseases; these were added to estimates in the relevant years. In 47 countries with an identified peak adult prevalence for HIV/AIDS of more than 0·5% and where VR systems were less than 65% complete, we informed our estimates of age-sex-specific mortality using the Estimation and Projection Package (EPP)-Spectrum model fitted to national HIV/AIDS prevalence surveys and antenatal clinic serosurveillance systems. We estimated stillbirths, early neonatal, late neonatal, and childhood mortality using both survey and VR data in spatiotemporal Gaussian process regression models. We estimated abridged life tables for all location-years using age-specific death rates. We grouped locations into development quintiles based on the Socio-demographic Index (SDI) and analysed mortality trends by quintile. Using spline regression, we estimated the expected mortality rate for each age-sex group as a function of SDI. We identified countries with higher life expectancy than expected by comparing observed life expectancy to anticipated life expectancy on the basis of development status alone. FINDINGS: Completeness in the registration of deaths increased from 28% in 1970 to a peak of 45% in 2013; completeness was lower after 2013 because of lags in reporting. Total deaths in children younger than 5 years decreased from 1970 to 2016, and slower decreases occurred at ages 5-24 years. By contrast, numbers of adult deaths increased in each 5-year age bracket above the age of 25 years. The distribution of annualised rates of change in age-specific mortality rate differed over the period 2000 to 2016 compared with earlier decades: increasing annualised rates of change were less frequent, although rising annualised rates of change still occurred in some locations, particularly for adolescent and younger adult age groups. Rates of stillbirths and under-5 mortality both decreased globally from 1970. Evidence for global convergence of death rates was mixed; although the absolute difference between age-standardised death rates narrowed between countries at the lowest and highest levels of SDI, the ratio of these death rates-a measure of relative inequality-increased slightly. There was a strong shift between 1970 and 2016 toward higher life expectancy, most noticeably at higher levels of SDI. Among countries with populations greater than 1 million in 2016, life expectancy at birth was highest for women in Japan, at 86·9 years (95% UI 86·7-87·2), and for men in Singapore, at 81·3 years (78·8-83·7) in 2016. Male life expectancy was generally lower than female life expectancy between 1970 and 2016, an

    Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
