In recent past, Ebola Hemorrhagic Fever (EHF) took a devastating toll on humanity, with its outbreak in mostly some West African countries, and with up to 90% mortality rate for those affected. As a result of the highly infectious nature of the ailment, there is urgent need for effective, accurate and fast diagnostic procedures. In this study, a Fuzzy Logic based approach is proposed, which is considered suitable for diagnosing EHF, especially at the early stage, before it becomes contagious. The system obtains responses (in linguistic terms) to symptoms such as, temperature, vomiting, bleeding, diarrhea, muscle pain, etc. from people suspected of being infected with the Ebola virus. It processes these responses using fuzzy classification approach to determine the possibility of Ebola virus infection. The advantage of this system is that, besides providing quick response alternative to the long period manual laboratory diagnosis, it also helps to reduce the likelihood that an uninfected person is quarantined or subjected to laboratory processes. It will aid early detection, thereby reducing further spread of the virus as well as mortality rate and stigmatization.

Thin films of tin (iv) oxide (SnO2) were deposited on six polished sample plates of stainless steel 430 using improved chemical bath deposition (CBD) method at 302 K and pH value of 12.4 for different deposition time of 16 to 36 h at 4 h interval, respectively. Ethylenediamine tetra acetate (EDTA) was used to stabilize the deposition at the required pH value. The thermal emittance values of the polished and coated sample plates were determined before and after the deposition of films, respectively, using thermocouple potentiometer. The average thermal emittance value of the uncoated polished sample plate is 0.15 ± 0.01 while thermal emittance values of the coated sample plates vary from 0.15 to 0.19 ±0.01. The film thickness of the coated sample plates varies from 33.73 to 77.59 μm. These low thermal emittance values compare well with those obtained for oxidized stainless steel selective surfaces. The coated sample plates with most favorable conditions of thermal emittance 0.17 to 0.18 ± 0.01 and film thickness 45.70 to 69.18 μm could find applications in photothermal conversion of solar energy. The improved chemical bath deposition technique could be employed at different pH values with suitable deposition time to fabricate selective surfaces for use in solar energy applications. © 2010 Academic Journals.

Determination of the overall rate controlling step in the biosorption of Methyl violet dye onto a new biosorbent, palm kernel fiber has been determined. Pseudo-second-order model described the kinetics over the whole contact time period for the effect of initial concentration and temperature. Using the Wu's approaching equilibrium factor, Rw, it was observed that the time for the switch from initial biosorption to intraparticle diffusion is affected by initial concentration and temperature. A comparison between the activation parameters of film diffusion, pseudo-second order ion exchange and intraparticle diffusion revealed that film diffusion is the overall slowest step in the biosorption process. Temperature increased the biosorption capacity but reduced slightly the rate of intraparticle diffusion, indicating that the biosorbent surface was activated by temperature which limited the diffusion of Methyl violet molecules into the interior of the biosorbent. A multistage process design to minimize mass and contact time was done. © 2011 Elsevier Ltd.

Based on local claims on the efficacy of Aframomum melegueta (alligator pepper) and Costus afer (ginger lily) in the treatment of malaria, the present study compared the antioxidant activity and phytochemical constituents of extracts of A. melegueta and C. afer leaves. Methanol extracts of the plant leaves were obtained using standard procedures. The antioxidant property of the plants extracts were evaluated using DPPH (1,1-diphenyl-1-picryl-hydrazyl) radical, Total Phenol Content (TPC), Total Flavonoid Content (TFC), Proanthocyanidin Content (PC), Ferric acid Reducing Antioxidant Potential (FRAP) and ThioBarbituric Acid Reducing Substances (TBARS) assay. The phytochemical screening test revealed the presence of alkaloids, reducing sugars, flavonoids, tannins, saponins, steroids, cardiac glycosides and terpenoids in both extracts. The antioxidant study showed that the A. melegueta extract had higher DPPH radical scavenging ability (IC50 of 122.25ug/ml), FRAP (35.38μmol Fe(II)/g) and TBARS (% inhibition of 62.08%) than C. afer (IC50 of 156.48ug/ml, 12.25 μmol Fe(II)/g, and 42.5%, respectively). The C. afer extract, however, recorded higher levels of TFC, PC and a lower TPC content when compared with the A. melegueta counterpart. The results suggest that C. afer and A. melegueta extracts could serve as free radical scavengers, acting as primary antioxidants. The results support local claims of their therapeutic uses in the treatment of malaria in folklore medicine. © 2015 Jordan Journal of Biological Sciences.

In this study, pure cultures of three antagonistic fungi, Trichoderma, Penicillium and Aspergillus species and a fungal pathogen, Sclerotium sp. were obtained after inoculation on potato dextrose agar (PDA) fortified with antibiotics to prevent bacterial contamination. Pathogenicity test was carried out when the antagonistic isolates were inoculated on PDA 24 h before and after Sclerotium inoculation. Of the three fungal antagonists evaluated for inhibitory efficacy, Trichoderma sp. proved to be the most effective as it exhibited the greatest inhibition to Sclerotium sp. (P<0.01) both at the initial and final tests. This was closely followed by Aspergillus sp. with inhibitory effect on the pathogen at both trials (P<0.01). However Penicillium sp. was slightly inhibitory against Sclerotium. Percentage inhibitions of the antagonists on Sclerotium by Trichoderma, Aspergillus, and Penicillium, were up to 81.36-80.29%, 88.35-73.12% and 56.98-46.24%, at the 6th day of inhibition at both trials, respectively. The result implied that the extent of inhibition by the fungi provides the use of potential antagonists capable of controlling the pathogenicity of Sclerotium sp. in crops for sustainable agriculture. © 2010 Friends Science Publishers.

Glycemic index has generated a lot of debate for nearly 30 years, especially as it relates to the control for the treatment of diabetes. This study determined the glycemic index (GI) of ten processed Nigerian foods and revealed their similarity in the release of glucose on consumption. The food items tested were made from yam tubers, cassava tubers and local cereals. These foods were served to human volunteers in several processed forms which resulted in viscous pastes. The GI results are related to the increased incidence of overweight and obesity in the middle class Nigerians. It is suggested that these processed foods should be discouraged in the regular dietary plan if Nigerians desire to stay slim and save the planet by reducing carbon emission and climate change.

This aim of this study is to review naturally occurring dietary chemotherapeutic bioactive agents in some african medicinal plants that can be put to therapeutic use in combating inflammation and carcinogenesis without posing any deleterious effects to normal cells, tissues, organs and systems. Flavonoids possess antioxidant activity and may play a beneficial role in cancer prevention, and offer some protection against diabetes and atherosclerosis. Polyphenol prevents oxygen free radical-induced hepatocyte lethality, prevent lipopolysaccharide-induced liver injury through inhibition of inducible nitric oxide synthase and tumor necrosis factor-a expression and inhibits carcinogen or toxininduced liver oxidative DNA damage. Acetogenins have cytotoxic properties against tumor cell lines. Cardiac glycosides helps in the treatment of congestive heart failure. Tannins exert antimicrobial activities by iron deprivation, hydrogen bounding or specific interactions with vital proteins such as enzymes in microbial cells. Terpenoid have hepatoprotective effects in albino rats.

High performance liquid chromatography (HPLC) was used to conduct an entomotoxicological analysis on puparia cases and adult insects bred from monocrotophos poisoned carrions. The results indicate that, the poison was better detected in puparia cases compared to adults. This is valuable as puparia abundance at carrion in the late stages of decomposition is a common phenomenon compared to maggots and adults. Hence, standard operating procedures for collecting entomological evidence at death scene involving heavily decomposed remains should focus on collecting puparia, as they could be a link to cause of death, especially when foul play by poisoning is suspected.

Outage probability is a key performance measure for real time traffic in wireless networks and is often considered as more critical than drop call probability. In this paper, we study the outage probability in a wireless mobile environment, where the interferers are distributed on the ground. Taking into consideration the background noise and the cell radius, we formulate an outage probability model coupled with observed data from Airtel Nigeria formally Zain Communications Limited, a Telecommunication company operating in Nigeria and simulate the system's performance using the Java programming language. We also present a geographical information system (GIS) solution showing the distribution of signal outages at various base stations in Akwa Ibom State (East region) of Nigeria for observed and simulated data. A performance evaluation of these data reveals that our model could greatly improve the system's performance. The results obtained allow us to study the stability of the network and evaluate the network in a more efficient and accurate manner. © 2011 Kavala Institute of Technology.

We have performed the electronic and phonon band structures of BxIn1-xN for various concentration of Boron using the pseudopotential method. The electronic band structure calculation was done using the GW approximation while the phonon band structure was done using the density functional perturbation theory. All calculations were done within the frame work of the density functional theory (DFT). From our calculations, the direct band gap for B0.25In0.75N, B0.5In0.5N and B0.75In0.25N were found to be 0.024eV, 2.2 eV and 6.01 eV respectively while the indirect band gap obtained were 0.59 eV, 3.24 eV and 6.9 eV. For the phonon calculations, it was also observed that an increase in the Boron content results in corresponding increase in the frequency of the topmost LO at the zone centre. For B0.25In0.75N, B0.5In0.5N and B0.75In0.25N, the topmost LO obtained were 735 cm-1, 885 cm-1 and 1105 cm-1 respectively. We also saw that as the Boron concentration decreases, the number of optical bands across which the acoustic bands overlap increases. © (2014) Trans Tech Publications, Switzerland.
