However, electrical efficiency and lifespan of solar photovoltaic panel tends to decrease due to the increase in surface temperature above the operation temperature of the panels due to its contact with the roofing sheets. The performance of solar photovoltaic panels was experimentally investigated on corrugated metal sheet (CMS) roof at four different heights (0, 100, 200, and 300mm). Four polycrystalline silicon photovoltaic panels of 10 watts each were selected from the same manufacturer. The temperatures on the roof and on the photovoltaic panels’ surfaces were measured at different solar hours. Also, the outputs of the solar panels together with the irradiance available were measured at same hours using an electronic data logger and imported to an Excel software. Irradiance variation, gap between r...

This research evaluated the toxicity effects of sub-chronic oral administration of Clinacanthus nutans ethanolic leaf extract in Institute of Cancer Research mice. A total 50, 8 w old female mice were divided into five groups of 10 mice each; Group A (control), Group B (125 mg/kg), Group C (250 mg/kg), Group D (500 mg/kg) and Group E (1000 mg/kg). The extract was administered orally for 90 d. The mice were monitored and sacrificed on d 91. Blood, liver and kidney samples were collected for analyses. There was significant (p<0.05) alterations in the haematological parameters of the mice in Group E and a significant increase in creatinine levels in groups B, C, D and E compared to A. The plasma level of alanine aminotransferase was significantly (p<0.05) higher in Groups D and E, compared to A. Histopathological evaluation of liver and kidneys revealed a moderate cytoplasmic vacuolation, eosinophilic cytoplasm and pyknosis of hepatocytes, as well as mild to moderate activated Kupffer cells in Group E. Similarly, the renal tubular cells showed mild to moderate renal cytoplasmic vacuolation, eosinophilic cytoplasm, pyknotic and karyolytic cells in Group E. It is concluded that repeated oral doses of Clinacanthus nutans ethanolic leaf extract for 90 d induced hepato-renal toxicities in female Institute of Cancer Research mice.

This review paper examines the growing literature on the impact of COVID-19 on the housing market to ascertain its positive and negative effects. Thus, a total of 40 published conference papers, thesis, academic journal articles, and others obtained from secondary sources were reviewed and revealed that the novel coronavirus (COVID-19) in some scenarios had positive and negative impacts on the housing market. The paper found that the positive impacts include a rise in housing prices, increase in housing supply and reduction in mass evictions in some locations, while the negative impacts are on housing prices, demand and supply, constraints in mortgage return maintenance and delay in the construction of new housing apartments. The paper, therefore, concludes that both positive and negative impacts of the COVID-19 pandemic are felt on the housing market globally. These thereby form a basis for fu...

Interruption or blockage of Chi brings about disorders, pain, and diseases. Acutherapy, therefore, aims at correcting the interruption or blockage of the harmonious flow of Chi along the meridian to restore the healthy condition of the body system. This correction could be accomplished by either acupuncture or acupressure, and are both collectively referred to as acutherapy. Thisform of therapy has been used in both humans and animals for several decades. It is, however, just gaining popularity in the treatment of humans and is still not yet in practice among veterinarians for animal patients in most developing countries like Nigeria. This review, therefore, is aimed at exposing veterinarians from the developing countries to the general application of acutherapy with emphasis on ...

It posits that a distinction needs to be made between child labor and child work. More so, until and unless we comprehend the background of families, the state of welfare, the potency of state mechanisms of control along political will, as well as the motives of the victims in relation to the consequences on the victims and the society in general, we cannot deal with the menace of child labor in the global south. This empirical study surveyed 311 child laborers in Kaduna Metropolis-Nigeria; conducted key informants' interviews; and utilized content analysis to generate the findings of the research. The data illustrate that the dynamics of child labor in the area of study is relatively common to children from poor and difficult parental backgrounds. It shows multiple consequences of such activities on schooling and general well-being of the children. It highlights the tendency for the children's future to be compromised with antecedent consequences such as increasing antisocial behaviors and the tendencies for transition from delinquency to criminality in the metropolis. Conversely, the data indicate that government is relenting on implementing measures to curb the problem. The study therefore recommends improved welfare provision by the state government, enhanced public private partnership (PPP), as well as private initiatives as collaborative efforts for empowerment. These efforts should be a bottom-top approach for the general well-being of notably the less-privileged in the metropolis.

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. Whether these phenotype and resistances that had no fitness cost to the bacterium could significantly affect the virulence of the bacteria in vivo remains to be investigated.

The study was aimed at identifying the extent of contamination of the notes in circulation, and to determine if job occupation has an influence in the bacterial contamination of currency notes, which serve as a medium of exchange. A total of 108 samples of the Nigerian currency note (Naira: N) of the following denominations; N5, N10, N20, N50, N100 and N200, were randomly collected from six (6) occupational groups namely: Fish/Meat sellers, Restaurant operators, Traders, Taxi drivers, Students and Banks. Samples were processed for bacterial isolation. 29 out of 108 samples yielded bacterial growth which gives a total recovery rate of 27%. Currency note with the highest contamination was N50 (24.1%), followed by N10 (17.2%), N100 (17.2%), N200 (17.2%), N20 (14%) and N5 (10.3%). Organisms isolated from the currency notes in descending order of prevalence include Staphylococcus spp (24.1%), Streptococcus spp (24.1%), Escherichia coli (17.2%), Klebsiella spp (13.8%), Enterobacter spp (10.3%), Pseudomonas spp (3.45%), Coliform bacteria (3.45%), and Candida spp (3.45%). Occupational group with the highest currency note contamination rate was Restaurant operators (31%), followed by Traders (24%), Fish/Meat sellers (21%), Taxi drivers (14%), Bank (7%) and Students (3%). N50 note collected from restaurant operators recorded the highest contamination rate of 14%. A significant relationship has been observed between occupation and level of contamination. We advocate that proper standards of hygiene should be observed to avoid contamination, and onward transmission of these pathogens.

Malaria prevalence studies had been undertaken in many parts of Nigeria but there is probably no data available from the far North Western region. This research study was undertaken to determine the prevalence, monthly distribution of malaria in Sokoto, North Western Nigeria in order to generate baseline information. A total of 1,297 blood samples were collected by simple random sampling, from patients attending the two health centres over the twelve calendar months. Thick and thin blood films were Giemsa stained and observed for the presence of malaria parasites. A total of 354 (27.29%) were positive for malaria parasites with the highest prevalence rate being recorded in the month of August with 72 (59.5%) positive cases and the month of March having the least infection rate of 9 (9.18%). The infection rate according to gender showed that males had the higher infection rate of 192 (n = 635) or 30.24% than the females who had a total 162 infection (n = 662) or 24.47%. The age group 0-5 years had the highest infection rate of 123 (43.77%) while the age group 36-40 years had the least infection rate of 10 (9.8%). The study has revealed the presence of malaria transmission throughout the year in Sokoto, North Western Nigeria and the infection rate can be considered as moderately high.

A total of 110 Pseudomonas aeruginosa was obtained from clinical wound samples in three tertiary hospitals in South West, Nigeria. Isolated pure cultures of bacteria were subjected to various morphology and biochemical tests. After which they were identified using Bergey's Manual of Systematic Bacteriology. One hundred and ten (110) Pseudomonas aeruginosa isolated from clinical wounds were subjected to antibiotic susceptibility testing by disk diffusion and plasmid profiling. Fifteen (15) different antibiotics discs were used to determine the drug sensitivity pattern of the isolates. Plasmids were extracted by the alkaline lysis method (Zymogen UK). Electrophoresis of the DNA was carried out on a 0.8% agarose gel. Variation occurred in multiple antibiotic resistance patterns among various strains of Pseudomonas aeruginosa isolated from the clinical wound samples. The antibiotic resistant pattern showed that Pseudomonas aeruginosa had high resistant to amoxicillin 92.7%, ampicillin 90%, cloxacillin 88.2%, cotrimoxazole 77.3%, erythromycin 72.7%, tetracycline 70.9%, streptomycin 65.5% and ofloxacin 60% and had low resistant to ceftazidime (20%), gentamycin (26.4%), levoxin (30.9%), ceftriaxone (34.5%) and ciprofloxacin (35.5%). Plasmid profile was carried out on 22 selected multi drug resistant (MDR) isolates that were resistant to three or more classes of antibiotics. Eight (36.4%) strains were found to possess plasmid bands. Six of the strains had single plasmid band while two strains possessed two bands with sizes ranging from 662 to 830bp. The sizes of the plasmids among P. aeruginosa isolates ranged from 662bp to 830bp. All the strains that had plasmids were resistant to amoxicillin, ampicillin, cloxacillin, cotrimoxazole, erythromycin and tetracycline.

It has about the worst maternal/child mortality rates in sub-Saharan Africa (NHR, 2007), it sits 143 among the 183 most corrupt countries of the world (Transparently International, 2011), and coupled with the fact that unemployment is arguably over 40% (Nigeria News Network, November 17, 2012). That these uncomplimentary indicators exists side-by-side great national wealth and potentials make the Nigerian situation a complicated paradox requiring urgent, systematic, and strategic efforts at a reversal. This paper argues that such strides should begin with reforming Nigeria's ailing public administration by way of repositioning it to both support and drive the processes of national development. It recommends, among others, purposeful political/administrative leadership, viable institutions of accountability, and huge investments in human capital development, as panacea for Nigeria's weak public administration, and impetus for sustainable national development.
