A palynological study of forty ditch-cutting samples from CHEV-2 well drilled offshore in the Niger Delta showed that the sediments were mainly deposited during the Miocene age. Palynological assemblage was dominated by pollen and spores with rare occurrence of dinoflagellate cysts. The stratigraphic ranges of Retitricolporites irregularis, Psilatricolporites crassus, Echitritricolporites spinosus, Zonocostites ramonae, Foveotricolporites crassiexius, Monoporites annulatus, Psilatricolporites operculatus, Multiareolites formosus, Podocarpus milanjianus and some other marker species were used to demarcate five informal palynogical zones in the study area.

We report the case of a 21-year-old patient, who had a stricture of the penile urethra. After failed endoscopic urethrotomy, he had resection of the stricture with end to end anastomotic urethroplasty. We describe this surgical technique and analyze epidemiological, therapeutic and prognostic characteristics of anterior urethral strictures.

Shelley’s lyrics of 1819-1820 have a common feature despite the diversity of the natural phenomena they touch upon. Shelley is seeking in the natural changes of the world analogies by which to reassure his most advocated faith that regeneration follows destruction. In this article I shall attempt to give substance to my claim that in these lyrics there is a pattern of scientific and ontological enquiry into Nature’s apparently chaotic changes, through which Shelley is trying to come to real understanding of the Permanent, amongst the Transitory. I will sometimes invoke the help of other poems such as Mont Blanc or Adonais

In this paper, the author has studied performance of a three unit redundant system with the impact of switch and human failure. A system with three identical unit has been considered for assessment of performance under 2-out –of -3: G; policy. In the system, a switch is used to transfer load from one unit to another unit. All three units of system are connected in parallel configuration and working under 2-out-of-3: G; policy. The system can have two types of failure partial failure and complete failure. Partial failure degrades the efficiency of system but the complete failure breakdown the system and stop functioning of the system. Switch failure and human failure are considered as complete failure. The system has two types of failure and two types of repair. General repair is employed to the partially failed system and Gumbel-Hougaard family copula distribution complete failed system. The system is studied by supplementary variable technique and various measures of reliability, such as availability, reliability, MTTF and profit functions have been discussed. Some particular cases have been discussed by taking different failure rates.

This paper discusses in detail different configurations for comparing the performances of different combinations of commonly used techniques for speech recognition and speaker identification. The Feature extraction techniques considered were MFCC, LPC and Autocorrelation. The feature matching techniques considered were VQ, HMM, DTW and ANN.

In the present study, 26 elderly subjects were recruited and randomly divided into 2 groups, that is, orange (low in antioxidant capacity) and pomegranate (high in antioxidant capacity) groups, and 250 mL of juice was consumed daily for 4 weeks. Changes in plasma antioxidant capacity, activity of antioxidant enzymes, contents of ascorbic acid, vitamin E, reduced glutathione, malondialdehyde, oxidized low-density lipoprotein and carbonyls, and the degree of DNA damage in mononuclear blood cells were measured. Urine samples were collected for determination of 8-hydroxy-2?- deoxyguanosine content. Increased plasma antioxidant capacity and decreased plasma carbonyl content were demonstrated after daily consumption of pomegranate juice. In comparison, orange juice consumption presented a less significant effect on antioxidant function in elderly subjects. It is concluded that daily consumption of pomegranate juices is potentially better than orange juice in improving antioxidant function in the elderly. Because the plasma ascorbic acid, vitamin E, and reduced glutathione contents did not differ significantly between the 2 groups in this study, the phenolics may be the functional components contained in pomegranate juice that accounted for the observations.

Pressure dependent exciton binding energy in a Cd0.8Zn0.2Te/ZnTe strained quantum dot is investigated with the geometrical confinement within the single band effective mass approximation. The interband transition energy as functions of dot radius and the hydrostatic pressure is brought out. Computations are carried out using variational formulism. The pressure induced oscillator strength and the nonlinear optical rectification coefficient of an exciton in a Cd0.8Zn0.2Te/ZnTe quantum dot are studied using matrix method. Our results show that the exciton binding energy, interband emission energy and the nonlinear optical rectification coefficient are strongly dependent on the geometrical confinement and the applied hydrostatic pressure values.

Over the past years, malaria was a major public health problem in Eritrea. But since 1998, it has experienced a dramatic decline in malaria incidence. In 2013, the MoH launched a massive expansion of the malaria prevention and control program. The program was aimed mainly at the reduction of malaria in populations living in all zobas of the country in general and in the malarious areas in particular. Since Endagergis is one of the malarious areas in Eritrea, the Government put much effort to reduce morbidity and mortality rates in this area. However, there is still a need to generate new information on the prevalence of malaria at the villages of Endagergis locality at the moment. A total of 30 blood slides were examined. Out of these 6 (20%) (95% CI; 5% - 34.9%) were found to be infected. The malaria parasite prevalence differed markedly among villages from 0 to 2.2%, with 40% of the five villages having no positive cases. Four (13.3%) of positive slides had P. falciparum and two (6.7%) had P. vivax. Among the total tested, 4 (28.6%) of the males and 2 (12.5%) of the females had malaria infection and infection was occurred in all age groups, with a slightly higher prevalence (66.7%) of the parasite observed in age groups of below 15 years old. This study reports a significant drop in the prevalence of malaria infection in the inhabitants of Endagergis locality, due to an appropriate implementation of many preventive strategies. However, malaria prevalence still exists in some areas of the locality and is strongly associated with presence of mosquito breeding sites. The prevalence varies according to location of villages with Endagergis, AdiGuor and AdiSeyabo showing statistically higher prevalence. Malaria prevalence was higher in August 2012 than in other months of the surveillance periods.

Polyphenols widely distributed in plants, fruits and vegetables have received considerable attention because of their physiological functions including antioxidant, antimutagenic and/or cancer preventive activities. The present study aims to process cocoa beans and to estimate the quantity of epicatechin after processing. The seeds of Theobroma cocoa were subjected to two different treatments. One set of seeds were allowed to boil and other for fermentation. Both the boiled seeds and fermented seeds were further grouped into two. The first group of boiled seeds was dried and deshelled (BNR), second group of seeds were dried and roasted (BR). The fermented seeds were then dried under sunlight and deshelled without roasting (FNR) and the other group of seeds was roasted and deshelled (FR). The obtained seeds were ground to cocoa liquor and polyphenols were extracted using various solvents and concentrated by rotary evaporation, and these solutions were subjected to HPLC analysis and eluted compounds were detected by monitoring UV absorbance at 280 nm. The calibration curves were compared against the standard which was run at same nm. The obtained calibration curves identified the presence of the polyphenolic compound-epicatechin at 6 min. The sample BNR possessed the maximum concentration of o.938mg/g of epicatechin whereas the sample FR doesn’t obtained any peak representing the presence of epicatechin. Hence the study concludes that processing that involves fermentation and heat reduced epicatechin content as well as antioxidant activity.

In this paper the numerical study of unsteady flow of a viscous incompressible fluid past an exponentially accelerated infinite vertical plate with radiation, viscous dissipation, chemical reaction and variable heat and mass diffusion have been analyzed in the porous medium. To obtain the non-similar momentum, energy, and concentration equations usual non-dimensional variables have been used. The dimensionless governing equations are solved numerically by explicit finite difference method. Here velocity, temperature and concentration fields are described graphically for the different physical parameters. Skin friction and Nusselt number profiles have been also described graphically here.
