Development of Fingerprint Biometric Attendance System for Non-Academic Staff in a Tertiary Institution

Institutions, companies and organisations where security and net productivity is vital, access to certain areas must be controlled and monitored through an automated system of attendance. Managing people is a difficult task for most of the organizations and maintaining the attendance record is an important factor in people management. When considering the academic institute, taking the attendance of non-academic staff on daily basis and maintaining the records is a major task. Manually taking attendance and maintaining it for a long time adds to the difficulty of this task as well as wastes a lot of time. For this reason, an efficient system is proposed in this paper to solve the problem of manual attendance. This system takes attendance electronically with the help of a fingerprint recognition system, and all the records are saved for subsequent operations. Staff biometric attendance system employs an automated system to calculate attendance of staff in an organization and do further calculations of monthly attendance summary in order to reduce human errors during calculations. In essence, the proposed system can be employed in curbing the problems of lateness, buddy punching and truancy in any institution, organization or establishment. The proposed system will also improve the productivity of any organization if properly implemented. Keywords: Institution, Attendance, Biometric, Fingerprin

Characterization of methicillin-resistant Staphylococcus aureus isolates from apparently healthy individuals in Malete, Kwara state, Nigeria

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is a common and continuously growing cause of nosocomial and community-acquired staphylococcal infections around the world. Screening for colonization with MRSA is a major aspect of control and limiting the spread of infections cause by this organism. We investigated the carriage of MRSA among apparently healthy individuals in four rural villages: Eleburu, Tapa, Atere and Apo all around semi-urban town-Malete, in Moro Local Government of Kwara State, Nigeria.Methods: Nasal swabs were collected from volunteered individuals and were cultured on mannitol salt agar and blood agar for isolation and identification of Staph aureus using standard microbiological techniques. Susceptibility to cefoxitin disc (30 ag) was used to determine MRSA status of the isolates. Molecular method was used to detect the gene responsible for resistance among MRSA isolates. Antimicrobial susceptibility test to commonly prescribed antibiotics was carried out using discs diffusion method.Results: Total number of individuals carrying Staph aureus in their nostrils was 42 (37.2 %). Antibiotics susceptibility profile of Staph aureus isolates showed 100 % resistance to cefuroxime, cefotaxime, cloxacillin and augmentin, and were 87 %, 81 %, 69 % and 23.8 % and 19 % resistant to tetracycline, ceftriaxone, erythromycin, ofloxacin and gentamicin respectively. A total of 6 (14%) Community –Acquired MRSA (CA-MRSA) isolates were recovered from individuals living in these villages. Molecular method detected muc and mecA genes in all the 6 (100%) CA-MRSA isolates and lukS-lukF was detected in 3 (50%) of the isolates.Conclusion: Detection of CA-MRSA strains among these rural dweller indicates that they are harbouring enhance virulence organism that may manifest a more severe disease condition. The danger associated with high prevalence of multidrug resistant Staph aureus and CAMRSA; and its consequential effects of poor drug administration in Nigeria was discussed. There is need to establish a more strict legislation and enforcement on drug control; and a body that would monitor production and appropriate use of antibiotics in the Nigeria.KEYWORDS: CA-MRSA, Staph aureus, Antibiotics, Rural Villages and Molecular Characterizatio

Spatial variability of solar quiet fields along 96° magnetic meridian in Africa:results from MAGDAS

We have used chains of Magnetic Data Acquisition System (MAGDAS) magnetometer records of the horizontal (H) and vertical (Z) magnetic field intensities during September 2008 to August 2009 (year of deep minimum) across Africa to study their variability during the quietest international days, which coincidently associated with the sudden stratospheric warming (SSW) event in January 2009. This selection of the most international quiet days is indicative of 80% that are strongly associated with days when unusually strong and prolonged sudden SSW event occurs in January 2009. Interestingly, in January, a significant magnitude depletion of solar quiet (Sq) equivalent current was observed near noon hours around the magnetic equator (Addis Ababa, ABB) compared to any other months along with a consistent significantly reduced value across the Northern Hemisphere and moderate decrease at the Southern Hemisphere. Also, we found that Nairobi and Dar es Salaam at the Southern Hemisphere, which are close to ABB (dip equator), are strongly prone to westward electric field compared to the magnetic equator and Khartoum at the Northern Hemisphere. Significant negative values of MSq(Z) magnitudes observed near noon hours at Hermanus indicate the presence of induced currents that suggest ocean effects along with reversal to significant positive values in the afternoon, which subsided before 1800 LT in almost all the months, indicate stronger influence of ionospheric currents. On seasonal variability of Sq(H), a slight depression at ABB during September equinox is one of the evidences of seasonal Sq focus shift. Latitudinal variability of Sq near-noon hours was also investigated

INFLUENCE OF INTER-ROW SPACING AND WEED CONTROL METHODS IN GROUNDNUT (Arachis hypogeal (L.)

Weed competition has been identified as one of the major obstacles in crop production. The produc-tion of groundnut is limited by high weed infestation resulting in yield losses ranging from 50 - 80% in Nigeria. Hence, the need to evaluate integrated weed control in its production. Field trials were there-fore conducted at the Teaching and Research Farm of the Federal University of Agriculture, Abeokuta (7o 20’ N, 30 23’ E) to evaluate the influence of inter-row spacing and weed control methods on growth and yield of groundnut during the wet seasons in 2009 and 2010. The experiment was a Randomised Complete Design (RCBD) laid out in a split plot with three replications. The main plot treatment con-sisted of three inter-row spacings of 60 cm, 75 cm and 90 cm while the subplots included five weed control treatments of commercial formulation of metolachlor plus promethyne mixture (codal) at 1.0 kg a.i/ha, codal at 1.0 kg a.i./ha followed by supplementary hoe weeding at 6 weeks after sowing (WAS), codal at 2 kg a.i./ha, hoe weeding at 3, 6 and 9 WAS and a weedy check. Inter-row spacings of 60 cm and 75 cm reduced weed growth with consequent higher yields compared to the inter-row spacings of 90 cm in the early season of 2009. Application of codal at 1.0 kg a.i./ha followed by supplementary hoe weeding at 6 WAS combined with 60cm inter-row spacing gave effective weed control and higher groundnut pod yield than hoe-weeded control in both years of experimentation

Itaconic Acid Production from Date Palm (Phoenix Dactylifera L) Using Fungi in Solid State Fermentation

This study evaluates the potentials of Phoenix dactylifera L (Date fruits) as possible alternative raw materials for itaconic acid production using naturally occurring fungi. Date fruit (pulp) was used as a substrate in solid state fermentation for the production of itaconic acid using naturally occurring fungus.The date fruit (pulp) was de-capped from its seed manually with the aid of a knife and dried in an oven at 60 0C and was grounded using an Excella Mixer grinder. The fungus used was naturally isolated by fermentation of substrate (date pulp) and was identified as Aspergillus niger. Proximate analysis was carried out on the substrate using standard methods. Parameters such as substrate concentration, inoculum size and fermentation period were varied using standard methods to determine its effect on itaconic acid production. Assay for itaconic acid production was carried out using standard methods at a wavelength of 385nm. Amount of itaconic acid produced was derived by translation of absorbance values on the itaconic acid curve. The substrate had a high carbohydrate content of 72.29%. The fermentation results showed maximum production of itaconic acid of 20.75±0.25mg/ml using 40g substrate, 15.13±1.13mg/ml using 2 ml inoculums size of spore suspension (2×105 spores/ml) and a maximum yield of 16.88±0.13mg/ml at day 1 of fermentation period. On optimization with 40g substrate and 2 ml inoculums for 3 days a maximum yield was observed at day 2 of fermentation with a maximum yield of 25.00±1.00mg/ml. The highest acidic level throughout the fermentation period was observed to be at pH 4.2. From the study it was concluded that date pulp is a promising substrate and could be utilized by Aspergillus niger for the production of itaconic acid

A Geographically-Restricted but Prevalent Mycobacterium tuberculosis Strain Identified in the West Midlands Region of the UK between 1995 and 2008

Background: We describe the identification of, and risk factors for, the single most prevalent Mycobacterium tuberculosis strain in the West Midlands region of the UK.Methodology/Principal Findings: Prospective 15-locus MIRU-VNTR genotyping of all M. tuberculosis isolates in the West Midlands between 2004 and 2008 was undertaken. Two retrospective epidemiological investigations were also undertaken using univariable and multivariable logistic regression analysis. The first study of all TB patients in the West Midlands between 2004 and 2008 identified a single prevalent strain in each of the study years (total 155/3,056 (5%) isolates). This prevalent MIRU-VNTR profile (32333 2432515314 434443183) remained clustered after typing with an additional 9-loci MIRU-VNTR and spoligotyping. The majority of these patients (122/155, 79%) resided in three major cities located within a 40 km radius. From the apparent geographical restriction, we have named this the "Mercian" strain. A multivariate analysis of all TB patients in the West Midlands identified that infection with a Mercian strain was significantly associated with being UK-born (OR = 9.03, 95% CI = 4.56-17.87, p 65 years old (OR = 0.25, 95% CI = 0.09-0.67, p < 0.01). A second more detailed investigation analyzed a cohort of 82 patients resident in Wolverhampton between 2003 and 2006. A significant association with being born in the UK remained after a multivariate analysis (OR = 9.68, 95% CI = 2.00-46.78, p < 0.01) and excess alcohol intake and cannabis use (OR = 6.26, 95% CI = 1.45-27.02, p = .01) were observed as social risk factors for infection.Conclusions/Significance: The continued consistent presence of the Mercian strain suggests ongoing community transmission. Whilst significant associations have been found, there may be other common risk factors yet to be identified. Future investigations should focus on targeting the relevant risk groups and elucidating the biological factors that mediate continued transmission of this strain

A Trial of Early Antiretrovirals and Isoniazid Preventive Therapy in Africa

BACKGROUND: In sub-Saharan Africa, the burden of human immunodeficiency virus (HIV)-associated tuberculosis is high. We conducted a trial with a 2-by-2 factorial design to assess the benefits of early antiretroviral therapy (ART), 6-month isoniazid preventive therapy (IPT), or both among HIV-infected adults with high CD4+ cell counts in Ivory Coast. METHODS: We included participants who had HIV type 1 infection and a CD4+ count of less than 800 cells per cubic millimeter and who met no criteria for starting ART according to World Health Organization (WHO) guidelines. Participants were randomly assigned to one of four treatment groups: deferred ART (ART initiation according to WHO criteria), deferred ART plus IPT, early ART (immediate ART initiation), or early ART plus IPT. The primary end point was a composite of diseases included in the case definition of the acquired immunodeficiency syndrome (AIDS), non-AIDS-defining cancer, non-AIDS-defining invasive bacterial disease, or death from any cause at 30 months. We used Cox proportional models to compare outcomes between the deferred-ART and early-ART strategies and between the IPT and no-IPT strategies. RESULTS: A total of 2056 patients (41% with a baseline CD4+ count of ≥500 cells per cubic millimeter) were followed for 4757 patient-years. A total of 204 primary end-point events were observed (3.8 events per 100 person-years; 95% confidence interval [CI], 3.3 to 4.4), including 68 in patients with a baseline CD4+ count of at least 500 cells per cubic millimeter (3.2 events per 100 person-years; 95% CI, 2.4 to 4.0). Tuberculosis and invasive bacterial diseases accounted for 42% and 27% of primary end-point events, respectively. The risk of death or severe HIV-related illness was lower with early ART than with deferred ART (adjusted hazard ratio, 0.56; 95% CI, 0.41 to 0.76; adjusted hazard ratio among patients with a baseline CD4+ count of ≥500 cells per cubic millimeter, 0.56; 95% CI, 0.33 to 0.94) and lower with IPT than with no IPT (adjusted hazard ratio, 0.65; 95% CI, 0.48 to 0.88; adjusted hazard ratio among patients with a baseline CD4+ count of ≥500 cells per cubic millimeter, 0.61; 95% CI, 0.36 to 1.01). The 30-month probability of grade 3 or 4 adverse events did not differ significantly among the strategies. CONCLUSIONS: In this African country, immediate ART and 6 months of IPT independently led to lower rates of severe illness than did deferred ART and no IPT, both overall and among patients with CD4+ counts of at least 500 cells per cubic millimeter.
