    An equation for predicting moisture loss or gain by gari grain packed in two types of materials was developed. From this, it may be possible to establish the storability of gari in these two packaging material. The equation took into account the permeabilities of the materials, which were determined experimentally. The validity of the equation was tested experimentally. High correlation coefficients were received for small packages, while observed values were found to be consistently lower than the predicted values with packages 25cm x 20cm x 1Ocm in size and above

    The success of inclusive development strategies in the post-2015 sustainable development agenda depends substantially on the adoption of common inclusive development policies among nations. Building on the relevance of a knowledge economy in the post-2015 development agenda, this study models the feasibility of common policies for inclusive human development in Sub-Saharan Africa (SSA). More specifically, we investigate the complementary role of knowledge diffusion in the inclusive benefits of mobile phone penetration in SSA from 2000 to 2012 by employing the Generalised Method of Moments. Knowledge diffusion variables include educational quality, innovation and Internet penetration. The main finding is that inclusive human development is persistently conditional on mobile phones in knowledge diffusion. Moreover, countries with low levels of inclusive human development are catching-up their counterparts with higher development. Policy implications are discussed with particular emphasis on how to leverage common knowledge economy initiatives for inclusive developmen

    <p>Abstract</p> <p>Background</p> <p>The management of burns remains a challenge in developing countries. Few data exist to document the extent of the problem. This study provides data from a suburban setting by documenting the epidemiology of burn injury and ascertaining outcome of management. This will help in planning strategies for prevention of burns and reducing severity of complications.</p> <p>Methods</p> <p>A total of 72 patients admitted for burns between January 1st, 2002 and December 31st, 2006 at the Irrua specialist teaching hospital were studied retrospectively. Sources of information were the case notes and operation registers. Data extracted included demographics as well as treatment methods and outcome</p> <p>Results</p> <p>The results revealed male to female ratio of 2.1:1. Over 50% of the injuries occurred at home. There was a seasonal variation with over 40% of injuries occurring between November and January. The commonest etiologic agent was flame burn from kerosene explosion. There were 7 deaths in the series.</p> <p>Conclusion</p> <p>Burns are preventable. We recommend adequate supply of unadulterated petroleum products and establishment of burn centers.</p

    Polycyclic Aromatic Hydrocarbon-degrading Bacteria from Aviation Fuel Spill Site at Ibeno, Nigeria

    Polycyclic aromatic hydrocarbon (PAH)–degrading bacteria were isolated from aviation fuel contaminated soil at Inua Eyet Ikot in Ibeno, Nigeria. PAH-degrading bacteria in the contaminated soil were isolated by enrichment culture technique. Isolates with high PAH degrading potential characterized by their extensive growth on PAH-supplemented minimal salt medium were screened for their naphthalene, phenanthrene and chrysene degradability. The screening medium which contained selected PAHs as the sole source of carbon and energy showed that Micrococcus varians AFS-2, Pseudomonas putida AFS-3 and Alcaligenes faecalis AFS-5 exhibited a concentration–dependent growth in all the PAH–compounds tested. There were visible changes in the color of growth medium suggesting the production of different metabolites. Their acclimation to different PAH substrates was also evident as A. faecalis AFS-5 isolated from chrysene grew well on other less complex aromatic compounds. The isolate exhibited best growth (0.44 OD600) when exposed to 10 ppm of chrysene for 5 days and could utilize up to 90 ppm of chrysene. This isolate and others with strong PAH-degrading potentials are recommended for bioremediation of PAHs in aviation fuel-contaminated sites in the tropics

    The manufacture of power hacksaw blades using worn out sawmill blades made of medium carbon steel has bean achieved. They were produced through carburization, hardening and tempering processes. The produced power hacksaw blade when compared with the imported one showed the former having a slightly higher wear rate than the latter. The result also showed that the tool life of the produced power hacksaw having a hardness value of 459BHN and the imported one of hardness value 575 BHN was 922.3mins and 1140mins respectively. Although, the imported hacksaw blade has a slightly higher tool life than the produced one, which may due to a higher hardness value, the produced power hacksaw blade compares favourably well with the imported hacksaw blade.Keywords: Power hacksaw blade, bone charcoal, tooth wear, tooth life, hardness value

    The parasitic infections associated with febrile conditions were studied in 4800 patients attending routine medical examination in different health institutions in Owerri, Nigeria between 2001 and 2004 (3 years). Stool smears, urine deposits and blood smears were used to detect gastrointestinal, urinary tract and blood parasites respectively. Gastrointestinal parasites such as Ascaris lumbricoides, Hookworm, Trichuris trichuria, Entamoeba histolytica, Taenia spp, Giardia intestinalis, Enterobius vermicularis and Balantidium coli were found in 1065(22.18%) of the study population. Urinary tract parasites, which included Trichomonas. vaginalis and Schistosoma haematobium, were found in 330(6.87%) of the study population and hemoparasites (P. falciparum and Onchocerca spp.) in 1260(26.25%). Mixed infections of gastrointestinal and hemoparasites, gastrointestinal and urinary tract parasites, hemoparasites and urinary tract parasites were recorded in 390(8.12%), 15(0.31%) and 165(3.43%) of the study population respectively. More male patients had their febrile conditions associated with gastro-intestinal tract (GIT) parasites than female for hookworm 255(5.31%), T. trichuria 240(5.00%), Giardia intestinalis 60(1.25%) and B. coli 105(2.18%), while female patients had more febrile condition associated with urinary tract parasites than males for T. virginals 345(7.18%). 21 years and above had the highest infection rate of 238(75.56%) for hemoparasites and lowest for GIT parasites 75(24.00%). 360(28.23%) and 240(18.82%) were infected with GIT and hemoparasites respectively in 6 – 12 years febrile patients tested. Infant (0 - 5yrs) had the lowest infection rates. There is need for proper diagnoses of the causes febrile conditions for early and proper treatment in the study area.

    This study evaluated the hepatoprotective effect of the aqueous and methanolic extracts of stem bark of Garcinia kola on acetaminophen-induced liver injury in rats. Twenty four (24) male Wister rats weighting between 116-247g were used for the study and the experimental animals were treated with graded doses of the aqueous (AE) and methanolic (ME) extracts of stem bark Garcinia kola for 7 days before induction of liver damage with 750mg/kg body weight of acetaminophen on the 8th day. At the end of the experimental period, serum samples were collected for biochemical studies and results showed markedly lowered mean values of liver maker enzymes (P&lt;0.001) with mean values of 52.90 + 4.21 IU/I, 12.8+ 3.93 IU/I and 14.00 + 2.21 IU/L for APL, ALT and AST respectively in group A (treated with 25mg/kg AE) when compared to respective mean values of 128.32 + 5.04 IU/L recorded in group E.This trend was also observed in groups B, C and D treated with 50mg/kg AE, 25mg.kg (ME) and 50mg/kg ME respectively. Also other biochemical parameters including total protein (TP) and albumin (ALB) showed mean values that demonstrated evidence of hepatroprotection in groups A-D when compared to group E. In conclusion, the aqueous and methanolic extracts of G. kola have been shown to have hepatoprotective activity and it is recommended that the phytochemical principles responsible for this effect be further elucidated through high resolution techniques.Key Words: Acetaminophen, ethnomedicine, hepatoprotective, Garcinia kol
