Bacterial Contaminants of Salad Vegetables in Abuja Municipal Area Council, Nigeria
Itohan, A. M.,Peters, O.,Kolo, I.
Malaysian Journal of Microbiology , 2011,
Abstract: Salad vegetables are essential part of people’s diet all around the world. They are usually consumed raw and often without heat treatment or thorough washing; hence have been known to serve as vehicles for the transmission of pathogenic microorganism associated with human diseases. Fresh samples of lettuce, carrot and cucumber collected from different markets and vendors in Abuja Municipal Area Council, Federal Capital Territory, Nigeria were evaluated for bacterial loads using spread plate agar dilution method. Bacterial loads ranged from 1.6 x 106 to 2.9 x 108 cfu/g. Escherichia coli, Klebsiella and Enterobacter were amongst the coliforms (lactose fermenters), while Proteus, Pseudomonas aeruginosa, Salmonella and Shigella were non-lactose fermenters associated with the samples. Staphylococcus aureus was isolated from majority of the samples.
Antimicrobial activity of non-steroidal anti-inflammatory drugs with respect to immunological response: Diclofenac sodium as a case study
T Umaru, CO Nwamba, I Kolo, UU Nwodo
African Journal of Biotechnology , 2009,
Abstract: The non-steroidal anti-inflammatory drugs (NSAIDs) as the name implies are compounds of nonsteroidal origin, with the capability of inhibiting/reducing inflammatory response associated with tissue injury which could be as a result of physical trauma, noxious chemicals or microorganisms. There is however reason to believe that these drugs, which confound disease progression by suppressing fever, pain and attenuating some of the cardinal manifestations of inflammation in a patient actually lessen the immunologic response to bacterial infection. This seemingly paradoxical property is the birth of this mini review. This review aims at invalidating the claims that NSAIDs in general lessen the immunological response to microbial infections by examining the antimicrobial properties of diclofenac sodium, an NSAID.
A Simple and Reliable Touch Sensitive Security System
A. M. Zungeru,J. G. Kolo,I. Olumide
Computer Science , 2012, DOI: 10.5121/ijnsa.2012.4512
Abstract: This research focuses on detection of unauthorized access to residential and commercial buildings when the residents are far away from the access gate of the house. The system is a simple and reliable touch activated security system and uses sensor technology to revolutionize the standards of living. The system provides a best solution to most of the problems faced by house owners in their daily life. Due to its simple electronic components nature, it is more adaptable and cost-effective. The system is divided into three units; the power supply unit which employs the use of both DC battery and mains supply to ensure constant power supply to the circuit, the trigger unit which is responsible for activating the alarm unit and designed to have much time and period and moderate sensitivity in order to reduce the rate of false alarm, and the alarm amplitude unit which main function is to produce amplitude alarm sound when triggered by the trigger unit with the aim of producing a large audible sound that can alert the entire neighborhood or scare an intruder away. The design of the system was achieved by considering some factors such as economy, availability of components and research materials, efficiency, compatibility and portability and also durability in the design process. The performance of the system after test met design specifications. This system works on the principle of touch sensor. The general operation of the system and performance is dependent on the presence of an intruder entering through the door and touching any part of the door. The overall system was constructed and tested and it work perfectly.

In 2016, the total estimated paddy production in Nigeria was 17.5 million metric tons (MMT) which is equivalent to 5.7 MMT milled rice. This is 1.3 MMT lower than the projected 7.0 MMT national consumption demands. This implies that Nigeria is progressing towards achieving self-sufficiency in rice if this data is compared with 3.5 MMT milled rice production in 2010. But about 10% - 30% or more of this increase does not reach the final consumers largely due to inefficient postharvest management practices. Huge postharvest grain loss (PHGL) and postharvest grain quality loss (PGQL) have been reported and significant efforts have been made towards reducing them and improving food security, but this is hampered by lack of simple, cost effective, adoptable and well-defined practical postharvest management practices and technologies. This situation has presented huge opportunity for investment and strategic interventions. From the point of harvest till rice reaches the consumers table, rice passes through wide range of unit operations which may have impact on the quantity and quality of the milled rice, these have made value chain actors adopt different practices to manage the process as it passes through the various unit operations. This paper examines the current rice post-harvest management technologies in Nigeria, with attention focusing on the current practices, constraints militating against the improvement of the rice postharvest system and opportunities it presents for improvement taking into account the main contribution of the research and development organizations in solving rice postharvest related challenges and lessons to be learned that will sharpen future direction for sustainable development.

Trials , 2012, DOI: 10.1186/1745-6215-13-59
Abstract: Patients aged 30 to 69?years with uncomplicated hypertension (140 to 179/90 to 109?mmHg) and ≤2 associated risk factors are eligible. After a four week run-in period off treatment, 180 patients have to be randomized to once daily bisoprolol/hydrochlorothiazide 5/6.25?mg (R) or amlodipine/valsartan 5/160?mg (E). To attain blood pressure <140/<90?mmHg during six months, the doses of bisoprolol and amlodipine should be increased to 10?mg/day with the possible addition of up to 2?g/day α-methyldopa.At the time of writing of this progress report, of 206 patients enrolled in the run-in period, 140 had been randomized. At randomization, the R and E groups were similar (P?≥?0.11) with respect to mean age (50.7?years), body mass index (28.2?kg/m2), blood pressure (153.9/91.5?mmHg) and the proportions of women (53.6%) and treatment na?ve patients (72.7%). After randomization, in the R and E groups combined, blood pressure dropped by 18.2/10.1?mmHg, 19.4/11.2?mmHg, 22.4/12.2?mmHg and 25.8/15.2?mmHg at weeks two (n?=?122), four (n?=?109), eight (n?=?57), and 12 (n?=?49), respectively. The control rate was >65% already at two weeks. At 12?weeks, 12 patients (24.5%) had progressed to the higher dose of R or E and/or had α-methyldopa added. Cohort analyses of 49 patients up to 12?weeks were confirmatory. Only two patients dropped out of the study.NOAAH (NCT01030458) demonstrated that blood pressure control can be achieved fast in Black patients born and living in Africa with a simple regimen consisting of a single-pill combination of two antihypertensive agents. NOAAH proves that randomized clinical trials of cardiovascular drugs in the indigenous populations of sub-Saharan Africa are feasible.
The role of plain radiographs in the diagnosis of chronic maxillary rhinosinusitis in adults

African Health Sciences , 2012,
Abstract: Background: Computed tomography is currently the gold standard for the diagnosis of chronic rhinosinusitis. However, this facility is not readily available in many developing countries. Thus, plain sinus radiography is still widely in use in our practice. Objectives: To assess the diagnostic value of plain radiographs in adult patients with uncomplicated chronic maxillary rhinosinusitis. Methods: This study was carried out at a tertiary health facility in Northern Nigeria. All adult patients with clinical and radiological diagnosis of chronic maxillary rhinosinusitis were included. Results: A total of 88 patients were recruited into the study. There were 51 males (58.0%) and 37 (42.0%) females. Their ages ranged from 18 to 60 years; with a mean age of 31.7+ 9.20 years. Mucosal thickening was the commonest diagnostic plain radiographic feature, and fluid level was the least. Maxillary antra with diagnostic plain radiographic interpretations of fluid level, haziness and opacity had high specificities (100%, 95.2%, and 85.7%) and high positive predictive values (100%, 75%, and 70%) respectively. Conclusions: Plain radiographs are relevant in the diagnosis of chronic maxillary rhinosinusitis in our locality only when they show features of fluid level: findings of haziness and opacity are of less diagnostic value.

Journal of Applied Sciences and Environmental Management , 2010,
Abstract: An in-situ measurement of the background radiation level was carried out at the vicinity of three campuses of two major tertiary institutions in Minna. A portable Geiger-Mueller tube-based environmental radiation dosimeter was used for the measurement. A total of 34 point was surveyed across the three institutions for background environmental radiation. The dose rate range obtained are: at the Niger State College of Education Minna (NCM), the dose rate varies from 0.125 μSv/hr to 0.171μSv/hr; at the Federal University of Technology Bosso Campus (FUTB) it wass between 0.152 μSv/hr and 0.184 μSv/hr; and at the Federal University of Technology Gidan- Kwano campus FUTG it was between 0.137 μSv/hr and 0.184 μSv/hr. In all the 34 points surveyed the mean dose rate was 0.154 μSv/hr with a standard deviation of 0.017 μSv/hr. Generally, the dose rate level in each of the institutions surveyed are comparable to one another and could simply be attributed to natural sources. The average annual effective dose obtained from this study is 0.189 mSv/annum which is still less than the recommended limit of 1mSv/annum by International Commission on Radiation Protection [ICRP] for non occupational population exposure.

Nigerian Veterinary Journal , 2006,
Abstract: In a survey of major constraints limiting commercial poultry production in Gombe metropolis, 2,121 poultry cases were presented at the Gombe State Veterinary Clinic between January 1995 and December 2004. Out of the total number of cases presented, Newcastle disease (ND) accounted for 14.66%, chronic respiratory disease (CRD) 12.31%, fowl typhoid (FT) 12.02%, coccidiosis 10.81%, fowl pox (FP) 10.33%, fowl cholera (FC) 8.63%, nutritional disorders 8.49%, ectoparasitism 7.49% while helminthosis accounted for 7.07%. Based on the analysis of 110 questionnaires administered to poultry farmers, ND was found to be the most prevalent accounting for 19.1% of the total, FP accounted for 15.7%, and helminthosis accounted for 2.2%. The results suggest that infectious, non-infectious, and parasitic diseases constituted the major constraints to successful commercial poultry production in Gombe State.
Design of a Smart Embedded Uninterrupted Power Supply System for Personal Computers
A. M. Zungeru,A. J. Garba,J. G. Kolo,M. S. Ahmed,I. Olumide
Computer Science , 2012, DOI: 10.5121/ijesa.2012.2401
Abstract: Digital equipment such as computers, telecommunication systems and instruments use microprocessors that operate at high frequencies allowing them to carry out millions or even billions of operations per second. A disturbance in the electrical supply lasting just a few milliseconds can affect thousands or millions of basic operations. The result may be malfunctioning and loss of data with dangerous or costly consequences (e.g. loss of production). That is why many loads, called sensitive or critical loads, require a supply that is protected. Many manufacturers of sensitive equipment specify very strict tolerances, much stricter than those in the distribution system for the supply of their equipment, one example being Computer Business Equipment Manufacturers Association for computer equipment against distribution system disturbances. The design of this uninterrupted power supply (UPS) for personal computer (PC) is necessitated due to a need for enhanced portability in the design of personal computer desktop workstations. Apart from its original functionality as a backup source of power, this design incorporates the unit within the system unit casing, thereby reducing the number of system components available. Also, the embedding of this unit removes the untidiness of connecting wires and makes the whole computer act like a laptop. Not to be left out is the choice of a microcontroller as an important part of the circuitry. This has eliminated the weight and space-consuming components that make up an original design. The singular use of this microcontroller places the UPS under the class of an advanced technology device.

Abstract: Data are presented on the reaction pbar-p -> omega-omega-pizero at rest from the Crystal Barrel detector. These data identify a strong signal due to f2(1565) -> omega-omega. The relative production from initial pbar-p states 3P2, 3P1 and 1S0 is well determined from omega-omega decay angular correlations; P-state annihilation dominates strongly. A combined fit is made with data on pbar-p -> 3pizero at rest, where f2(1565) -> pizero-pizero is observed.
