Abstract: This work aims at analyzing the bioactive and anti-nutritional compounds of edible and wild beans when unprocessed and malted. Qualitative screening of phytochemicals in the various bean samples was determined in ethanol and petroleum ether solvents. Results of the anti-nutritional compositions of unprocessed wild bean extracted with petroleum ether showed there were no traces of saponin and polyphenol, in Feregede and also in edible bean-IT07K-243-1-10 which also had no traces of saponin and tannin. After malting, saponin was totally absent in Pakala, Mucuna, IT97k-499-35, IT07k-243-1-10, and IT04k-333-2 respectively. Polyphenol was also found to be absent in IT07k-243-1-10. Mucuna has the highest phytic acid level (7.8867 ± 0.011) while Feregede has the lowest phytic acid level (2.9810 ± 0.004). Otili has the highest anti-trypsin level (12.001 ± 0.0013). This study showed varying levels of anti-nutrients on the respective bean samples when unprocessed but decreased marginally after malting. It was keenly noted that values derived, either before and after malting were not significantly different (P ≤ 0.05) from each other. In all, this study had further shown that malting process enhanced removal of anti-nutrients which invariably would lead to availability of nutrient for animal and human consumption.

Abstract: This work was set out to assay for some minerals essential for healthy state and biochemical indices that underlined degenerative diseases in some edible bean cultivar and nearly extinct local wild bean. Against this backdrop, ash composition was determined before Na , K , Ca2 , Mg2 , Zn2 , Fe2 , Pb2 and Cd were determined by Flame Photometer and Atomic Absorption Spectroscopy (AAS) respectively. 2,2-diphenyl-1-picrylhydrazyl (DPPH), Vitamin E and Vitamin C were also assayed to determine the scavenging ability of the bean samples. The proximate ash composition result of unprocessed and malted edible bean IT99K-573-2-1 had the highest ash content value of 6.90 ± 0.01 and 6.92 ± 0.01 respectively. In the bean samples Pb2 and Cd2 were not detected. The empirical mineral composition varies across both the wild and edible bean without significant difference (P ≤ 0.05) except IT07K-243-1-10 that had Ca2 to be significantly higher than other bean samples. K was found to be significantly higher in Feregede and IT07K-243-1-10 compared to other bean samples. Changes in the radical scavenging ability of the various sample in this study after malting, showed a slight reduction in DPPH content except for the edible beans—IT04K-333-2 and IT845-2246-4. Well, there was slight reduction of Vitamin E only in Otili, Mucuna and IT99K-573-1-1. Compared to others only Otili and IT845-2246-4 had slight reduction in Vitamin C after malting.

Abstract: In this study on bean, four wild types were compared with the edible for their functional and nutritional characteristics in unprocessed and malted form. Results obtained in functional properties showed that bulk density was higher in wild types compared to edibles types. Feregede has the least dispersibility compared to all the bean samples. The swelling power of all the wild and edible types was almost the same with the edible bean IT845-2246-4 having the highest value of 26.15 ± 0.02. Pakala had the broadest foaming stability even up to the region of alkaline pH. In proximate compositions, the entire edible bean had more carbohydrate and crude fibre content than the wild types but after malting, there was no significant difference (P < 0.05) in the crude fibre content between the edible and the wild type beans. After malting, it was observed that Pakala and edible bean IT99K-573-1-1 had more moisture content with the values 9.2 ± 0.14 and 9 ± 0.15 respectively. There was no significant difference in the protein content across both the wild and edible bean and ranged between 28.45 ± 0.012 and 30.70 ± 0.014 while these values were slightly reduced after malting. This study reveals that Mucuna and other types of underutilized wild beans— Otili, Feregede, and Pakala are important food sources that can be exploited to mitigate shortage in animal protein and under nutrition facing families in many developing countries particularly in Nigeria.

This work is an investigation of the curative effects of some edible and wild type beans on colonic inflammation induced by Dextran Sulphate Sodium (DSS) in wister albino rats. Macroscopic examination performed on the colon after seven-day exposure of the animals to both DSS and bean sample revealed a high incidence of colonic inflammation in rats fed with macuna compared to other groups. However, from the histological examination, the groups fed with Otili and Feregede had a low incidence of dysplasia showing Otili and Feregede to be good candidates that could mitigate effect of Dextran Sodium Sulphate.

Abstract: Creating a sustainable energy and environment, alternative energy is needed to be developed instead of using fossil fuels. This research describe a comparison of the use of pyrolysis oils which are the tire pyrolysis oil, plastic pyrolysis oil and diesel oil in the assessment of engine performance, and feasibility analysis. Pyrolysis oils from waste tire and waste plastic are studied to apply with one cylinder multipurpose agriculture diesel engine. It is found that without engine modification, the tire pyrolysis offers better engine performance whereas the heating value of the plastic pyrolysis oil is higher. The plastic pyrolysis oil could improve performance by modifying engine. The economic analysis shows that the pyrolysis oil is able to replace diesel in terms of engine performance and energy output if the price of pyrolysis oil is not greater than 85% of diesel oil.

C. Ravichandran, N. Malmurugan
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.78107
Abstract: Nowadays video coding approach is a major key in many applications for easy transmission and storage consumption. The process of transformation is based on the empirical wavelet transform (EWT). The encoding process of video data provides secure and less consumption of storage and the reconstruction process consists of the reverse process with the extraction. In this paper, the coding of video is carried out at a very low bit rate with the enhancement of performance by proposing an approach of modified Set Partitioning in Hierarchical Tree (MSPIHT). This method encodes the high frequency frames with the scheduling of wavelet transform for efficient performances of encoding and improves the ability of both the frequency and time. By applying empirical wavelet transform on each video frame, the component of video frequency is extracted and the?low frequency frame is encoded by the H.264/AVC standard. The low coefficient values are ignored in applying the threshold and in the reconstruction process, HBLPCE method is used for?imaging?enhancement. The simulation of the proposed approach analysis shows better performance in reliable process and efficiency when compared to existing.

Open Journal of Anesthesiology (OJAnes) , 2014, DOI: 10.4236/ojanes.2014.410035
Abstract: Background: The laryngeal mask airway (LMA) has become popular due to simplicity of its use and its important function in difficult airway management. However, some complications have been associated with its use. A case report and review of literature on hiccups associated with the use of LMA is presented. Case Report: A 24-year-old man who presented with a right inguinoscrotal hernia was scheduled for elective surgery under general anaesthesia. He denied any co-existing medical illness. Physical examination showed a normal healthy patient and he was placed in class 1 of the American Society of Anesthesiologist (ASA) physical status category. After premedication with 0.6 mg atropine, general anaesthesia was induced with 200 mg of intravenous propofol. Size 5 classic LMA was inserted, and surgery had lasted for 45 minutes. He had hiccups immediately after removal of the LMA which lasted for 6 minutes, and stopped about 95 seconds after 0.6 mg intravenous atropine was given. Conclusion: Complications from the use of LMA may be rare but still possible. It is important to adhere to the guidelines for insertion and removal of the LMA and perioperative use of the device should strictly be by trained personnel.

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2012, DOI: 10.4236/jmmce.2012.118063
Abstract: Al-7075 alloy-base matrix, reinforced with mixtures of silicon carbide (SiC) and boron carbide (B4C) particles, know as hybrid composites have been fabricated by stir casting technique (liquid metallurgy route) and optimized at different parameters like sliding speed, applied load, sliding time, and percentage of reinforcement by Taguchi method. The specimens were examined by Rockwell hardness test machine, Pin on Disc, Scanning Electron Microscope (SEM) and Optical Microscope. A plan of experiment generated through Taguchi’s technique is used to conduct experiments based on L27 orthogonal array. The developed ANOVA and the regression equations were used to find the optimum wear as well as co-efficient of friction under the influence of sliding speed, applied load, sliding time and percentage of reinforcement. The dry sliding wear resistance was analyzed on the basis of “smaller the best”. Finally, confirmation tests were carried out to verify the experimental results.

Objectives: To identify causes of low vision among the patients in the Eye clinic of University of Nigeria Teaching Hospital (UNTH). Methods: This was a cross-sectional study of all new consecutive low vision patients seen at the eye clinic of University of Nigeria Teaching Hospital-(UNTH) Ituku-Ozalla. All patients with low vision were evaluated by the researcher and the findings entered on a research protocol. Data were analyzed using descriptive statistics to generate frequency and percentage distributions and analytical statistics to test for significance of observed inter-group differences. In all comparisons, statistical significance was indicated by p < 0.05. Results: A total of 197 patients were seen comprising of 120 males and 77 females (M:F = 1.6:1) aged 39.3 ± 22.9 SD years. The main causes of low vision in the study population were glaucoma (36.0%), followed by oculocutaneous albinism (14.7%). The mean presenting distant VA was logMAR 1.1 (95% CI), while the mean near VA is logMar 1.0 (6/60, 20/200). After refraction, the mean distant VA was logMar 1.0, using unpaired t-test, the difference between the distant presenting and refracted VA were not statistically significant. 57.9% had distant VA after optical low vision assessment of logMar 0.9 - logMar - 0.2 while the mean distant VA was logMar 0.8 which was statistically significant. Near vision after optical assessment improved with a mean of logMar 0.8, which was statistically significant. Conclusion: Glaucoma was the commonest cause of low vision in this study. Optical low vision aids improved the visual functions of majority of the patients in this study.

Abstract: Urinary tract infections (UTIs) are one of the most prevalent extra-intestinal bacterial infections. It is a common disease encountered in medical practice affecting people of all ages, from neonate to geriatric age group. These infections are on the increase for outpatients attending Primary Health Centres in Anambra State, Nigeria, therefore the need for this study. The prevalence rate of urinary tract infection, age distribution and influence of sex were determined. Susceptibility pattern of the infectious organisms to antimicrobial agent were examined. Clean-catch midstream urine samples were collected and examined. Out of 3000 urine samples examined, 528 bacterial isolates were recovered and characterized. These include: Escherichia coli (24.2%), Klebsiella spp. (18.2%), Staphylococcus aureus (18.2%), Proteus mirabilis (9.1%), Pseudomonas aeruginosa (9.1%), Enterococcus faecalis (9.1%), Citrobacter intermedius (6.1%) and Staphylococcus saprophyticus (6.1%). More females (52%) were infected than males (48%) and in both sexes, the highest incidence was found amongst the age group, 26 - 38 years. Gram negative rods had the highest incidence in both sexes. Among the towns in Anambra state, Umunya in southern province was observed to have the highest incidence rate of UTI. Susceptibility test of the bacterial isolates to antimicrobial agents showed that Staphylococcus aureus was sensitive to Cephalexin, Penicillin V, Erythromycin and Gentamycin while Pseudomonas aeruginosa was resistant to all the antibiotics.
