As a result of the challenges of the manual method of taking attendance in schools and colleges in Nigeria, an automated attendance system needs to be adopted. The challenges include difficulty in keeping the attendance list over a long period of time, unnecessary time wastage during writing or signing, improper documentation, students forgetting to write or sign the attendance paper, lecturers forgetting the attendance list in the classroom, students writing or signing illegally for an absentee among others. This paper implements Radio frequency identification (RFID) automatic attendance system in Nigeria educational institutions which provides the functionalities of registering students, recording attendance, making decision on the eligibility of a student to sit for an examination in a course and other functions. This work eradicates the deficiencies associated with the manual attendance system with an automated approach implemented through Radio frequency identification (RFID) technology. The case study is Federal University of Technology, Akure, Nigeria.

We study the character pseudo - amenability of semigroup algebras. We focus on certain semigroups such as inverse semigroup with uniformly locally finite idempotent set and Brandt semigroup and study the character pseudo - amenability of semigroup algebra l1(S) in relation to the semigroup S: In particular, we show that for a unital cancellative semigroup S; the character pseudo-amenability of l1(S) is equivalent to its amenability, this is in turn equivalent to S being an amenable group.

Purpose: To describe and evaluate the efficacy of the slit-integration method in the prevention of ring recurrence after graft substitution urethroplasty. Materials and Methods: This was a pilot study of selected patients with urethral stricture disease who required urethroplasty from January 2016 to December 2018. Patients were recruited into the study after they granted informed consent about the procedure. Results: A total of eight patients were involved in this pilot study. The mean age (±standard deviation, SD) of the patients and the mean stricture length (±SD) were 44.25 (±11.07) years and 3.88 (±1.25) cm, respectively. The peno-bulbar region was the most frequently involved. The majority of the patients, 7 of 8 patients, underwent buccal mucosal graft repair with a mean graft length of 5.88 cm (range, 4–8 cm). There was leak during pericatheter urethrography in one patient. The mean (±SD) urethral calibers of the distal and proximal urethral anastomotic sites following urethroplasty were 26.00 (±1.85) and 25.25 (±1.83) at 1 week after removal of the urethral catheter stent and 27.75 (±0.71) and 27.75 (±0.71) at 12 months postoperatively, respectively. The mean maximum flow rate (±SD) at the 6- and 12-month follow-up was 20.25 (±1.83) and 21.88 (±1.73) mL/s, respectively. Conclusions: A slit-graft appropriately quilted into the corresponding urethrotomy incisions at the proximal and distal summit of the urethral stricture segments appears to mitigate the occurrence of ring contracture after urethroplasty. A randomized controlled trial of this technique with additional outcome assessment will be required to validate this observation.

Extraction of oil from Moringa oleifera seed using Response Surface Methodology (RSM) was investigated. Effects of three factors namely: sample mass, particle size and extraction time on the response, Moringa oleifera a volume extracted, were determined. The Box-Behnken design of RSM was employed which resulted in 15 experimental runs. Extraction was carried out in a 250 ml Soxhlet extractor with Hexane and Ethanol as solvent. The Moringa oleifera seed powder was packed inside a muslin cloth placed in a thimble of the Soxhlet extractor. The extraction was carried out at 60℃ using thermostatic heating mantle. The solvent in the extracted oil was evaporated and the resulting oil further dried to constant weight in the oven. This study demonstrates that Moringa oleifera oil can be extracted from its seed using ethanol and acetone as extraction solvent. The optimum process variables for both solvent (ethanol and acetone) was determined at sample weight of 40 g, particle size of 325 ㎛ and extraction time of 8 hours. It can be deduced that using acetone as solvent produces a higher yield of oil at the same optimum variable conditions compared to when ethanol was used.

<▼1><P><B>Background</B></P><P>The burden of typhoid in sub-Saharan African (SSA) countries has been difficult to estimate, in part, due to suboptimal laboratory diagnostics. However, surveillance blood cultures at two sites in Nigeria have identified typhoid associated with <I>Salmonella enterica</I> serovar Typhi (<I>S</I>. Typhi) as an important cause of bacteremia in children.</P><P><B>Methods</B></P><P>A total of 128 <I>S</I>. Typhi isolates from these studies in Nigeria were whole-genome sequenced, and the resulting data was used to place these Nigerian isolates into a worldwide context based on their phylogeny and carriage of molecular determinants of antibiotic resistance.</P><P><B>Results</B></P><P>Several distinct <I>S</I>. Typhi genotypes were identified in Nigeria that were related to other clusters of <I>S</I>. Typhi isolates from north, west and central regions of Africa. The rapidly expanding <I>S</I>. Typhi clade 4.3.1 (H58) previously associated with multiple antimicrobial resistances in Asia and in east, central and southern Africa, was not detected in this study. However, antimicrobial resistance was common amongst the Nigerian isolates and was associated with several plasmids, including the IncHI1 plasmid commonly associated with <I>S</I>. Typhi.</P><P><B>Conclusions</B></P><P>These data indicate that typhoid in Nigeria was established through multiple independent introductions into the country, with evidence of regional spread. MDR typhoid appears to be evolving independently of the haplotype H58 found in other typhoid endemic countries. This study highlights an urgent need for routine surveillance to monitor the epidemiology of typhoid and evolution of antimicrobial resistance within the bacterial population as a means to facilitate public health interventions to reduce the substantial morbidity and mortality of typhoid.</P></▼1><▼2><P><B>Author Summary</B></P><P>Typhoid fever, a serious bloodstream infection caused by the bacterium <I>Salmonella</I> Typhi, is a major cause of disease and death around the world. There have been limited data on the epidemiology of typhoid in many countries in sub-Saharan African, including Nigeria. Recent evidence, however, showed that typhoid was an important cause of bacteraemia in children residing in two regions of Nigeria. Here, we analyzed the whole genome sequences of 128 <I>S</I>. Typhi isolates from two studies in order to elucidate the population structure and characterize the genetic components of antimicrobial resistance. We found that the multiple <I>S</I>. Typhi genotypes identified were closely related to other <I>S</I>. Typhi from neighboring regions of Africa and that multidrug resistance (MDR) was common among these isolates, and in many cases was associated with the IncHI1 plasmid known to cause MDR typhoid. These results provide evidence that typhoid was established in Nigeria as a result of several independent introductions into the country and that there has been extensive exchange of <I>S</I>. Typhi in and around the region of West Africa. This study emphasizes the importance of surveillance to improve our understanding of the epidemiology of typhoid, which is needed to underpin public health measures to reduce the spread of disease and facilitate patient management.</P></▼2>
