The study examined the levels of resource-use efficiency of rice farmers unde,r irrigation method in Dadinkowa, Gombe state of Nigeria. Using questionnaire, data were collected during the year 2010 irrigation season from 120 randomly sampled rice irrigators and the data were analyzed using multiple regression and marginal analyses. Results showed that significant factors influencing irrigated rice production were labour （P 〈 0.001）, land and fertilizer （P 〈 0.01）. In addition, the coefficient of determination （R2）, the F-ratio and the standard error of the mean （S） were found to be 0.471, 16.37＊＊＊ and 8.908, respectively. The results also indicated that efficiency values of land, seeds, fertilizer and labour were 1.234, 0.498, 2.352 and 1.620, respectively. Finally, it was found that resource-use among the farmers were not efficient thus equipment, land, fertilizer and labour inputs shall be increased by 78.3%, 18.9%, 57.5% and 38.3%, respectively, while seed input shall be reduced by 50.2% for the farmers to attain optimal resource utilization.

The study assessed the Challenges Militating against the Effectiveness of Knowledge Management (KM) in Sustainable Land Use and Agricultural Production among Agricultural Extension Workers in Sokoto State, Nigeria. A sample size of 188 was drawn using well-structured questionnaires and was used for the study. Descriptive statistics and logit model were as tools of data analysis. The result of the study indicated that 53.7% of the extension Workers highlighted that lack of top Management support as major challenges for effectiveness of knowledge management among agricultural extension workers. The result of the logit model indicated that marital status, education level, experience, cosmopolitness and means of transportation had positive and significant relationship with effectiveness of Knowledge management. It was recommended therefore that Knowledge Management should be given top management support in all government establishments.

Chinese Business Review 2017年第2期16卷 102-108页

作者： Naziru suleiman Zaleha Othman abubakar Tafawa Balewa University Bauchi Nigeria Universiti Utara Malaysia Kedah Malaysia

Corruption is increasingly becoming a global phenomenon virtually affecting every part of the world. The effects have been very devastating particularly in the developing nations, by which to a large extent public service functions thrive in an environment heavily characterized by corruption. This paper reviews the relevant and related literature on corruption and then proposes a classification of the type of corruption based on the review.

Risk Assessment from Catchment to Consumers as Framed in Water Safety Plans: A Study from Maiduguri Water Treatment Plant, North East Nigeria

Water safety plan as conceived by WHO can lead to prevention of pollution in each component of water supply chain which leads to ensuring safe drinking water. Risk assessment is one of the key components during the development of water safety plan, achieved by identifying hazardous events and estimating their risk towards implementing control measures. This study reports the risk assessment from catchment to consumers in Maiduguri water treatment plant in Northeast Nigeria. Tools such as the field visits, key informant interviews, questionnaire and water quality monitoring were used to identify the hazards and estimate their risk using semi-quantitative matrix. With the existing control measures, the study showed a total of 33 hazardous events;5 in catchment, 16 in treatment plant, 6 in distribution system and 6 at consumers’ points. The risk score indicated 6 are of medium risk and 9 of high risk. Catchment activities, upgrade of treatment facilities and lack of routine maintenance in the treatment plant, pipeline damages in distribution lines, and consumers’ lack of hygiene knowledge and awareness were found to be the major contributory factors which affect the desired quality. Therefore participation and commitment by all relevant stakeholders are fundamental requisite to manage the identified health risks.

Hypermucoviscosity in Clinical Isolates of Klebsiella pneumoniae Correlates with High Multiple Antibiotic Resistance (MAR) Index

引用

Open Journal of Medical Microbiology 2016年第3期6卷 97-103页

作者： Uzal Umar Sandra Anagor Abdullahi Aliyu Abdulmumini Ibrahim suleiman Department of Biological Sciences Abubakar Tafawa Balewa University Bauchi Nigeria Department of Clinical Microbiology Abubakar Tafawa Balewa University Teaching Hospital Bauchi Nigeria

Klebsiella pneumoniae is an opportunistic pathogen of medical importance and the capsule and mucoid phenotype in this organism are considered as requisite virulence determinants. A total of 62 clinical samples from ATBUTH were collected and screened for K. pneumoniae. The isolates were identified using standard tests for this organism. The string test was used to detect the mucoid (hypermucoviscous) phenotype and the antimicrobial susceptibility test to 10 antibiotics was carried out with the disk diffusion technique after standardizing inoculum. A K. pneumoniae prevalence of 24% (15/62) was obtained of which 47% (7/15) were mucoid (hypermucoviscous) and 53% (8/15) were non-mucoid. Colonial sizes of the two strains do not reveal any significant differences in growth fitness of the strains. On blood agar, the mucoid and non-mucoid strains had a mean colonial size ± standard deviations of 4.41 ± 0.58 mm and 4.27 ± 0.42 mm respectively. The antibiotic susceptibility rate showed that the mucoid strains compared to the non-mucoid were more resistant to nine out of 10 antibiotics. The mucoid strains were outrightly resistant to augmentin, amoxicillin, septrin, sparfloxacin and perfloxacin. The non-mucoid strains showed no complete resistant to any antibiotic tested but had a higher resistant rate to chloramphenicol only. The Multiple Antibiotic Resistance (MAR) index shows the themucoid strains with a high MAR index range of 0.7 - 1.0 with a median MAR index of 0.8, while the non-mucoid strains had a MAR index of 0.2 - 0.8 with a median MAR index of 0.35. The data suggest that the mucoid phenotype could be associated with extrachromsomal element(s) carrying resistance genes to antibiotics and that these extrachromosomal elements may not harbour resistance determinants to chloramphenicol. Furthermore, the extrachromosomal elements bearing the mucoid phenotype and the resistance elements in the mucoid strains do not significantly impact on the fitness of the cognate strain.
