Prevalence of Trichomonas vaginalis Infection among Pregnant Women in Abeokuta, Nigeria

Trichomoniasis caused by Trichomonas vaginalis has emerged as one of the most common sexually transmitted infections. The infection may lead to an important complication in pregnancy, as it has been related with prematurity and low birth weight. The aim of this study was to determine the prevalence of T. vaginalis among Nigerian women attending ante natal clinic at the State Hospital, Abeokuta. A cross-sectional descriptive study was conducted among two hundred (200) pregnant women attending ante-natal at Ogun State Hospital, Abeokuta. High vaginal swabs (HVS) and urine samples were collected from consenting pregnant women and examined for the presence of T. vaginalis under the microscope. Out of 200 women, a total of 40 (20%) were found to be infected with T. vaginalis. The women between the age group 20-30 had the highest prevalence of 21.3% while age group >20 years had the lowest of 12.5% but the difference was not statistically significant. Women in second trimester had the highest prevalence of 25% while those of first trimester were the lowest with 18%. Results obtained from comparing HVS and urine microscopy in this study showed that HVS had a prevalence of 40% compared to urine microscopy (5.5%) and the difference in their detection was statistically significant p=0.0041. These results may be useful for health authorities, especially for ante-natal care and protection against STDs. The higher recovery rate obtained by using HVS microscopy confirms its advantage over urine microscopy.
DEVELOPMENT TRENDS OF PROCESS ENERGY SOURCES FOR SPECIAL APPLICATIONS OF THE SPARK EROSION

The process energy source is the main unit of the electrotechnical system for the spark erosion. The different fields of EDM application have made it necessary to develop different types of energy sources. In this paper, a brief review of the main types of energy sources is presented and the specific uses that are supposed to deal with. The examples are needle pulse energy sources with very short pulse duration (< 500 ns) and series-parallel resonant converters. The short needle pulse source does not produce any thermal-affected zone at the workpiece so that refinishing is not necessary. The series-parallel resonant converter can be forced in the robotics technology, which is of special interest for operations in critical rooms or environment.

Occupational Tasks in the German Labour Market: an alternative measurement on the basis of an expert database

"In recent times, the concept of tasks increasingly arises in the literature. Tasks defined as occupational tasks that individuals have to perform get more and more important in analysing different research questions. The most common application is the task-based approach (Autor/Levy/Murnane 2003) that explains rising wage inequality in many industrialised countries by changing tasks. However, the distinction between analytical/interactive and manual non-routine tasks as well as cognitive and manual routine tasks also provides a basic concept for further research on tasks like a task-based analysis of occupational segmentation of the labour market or occupational mobility. In contrast to the existing task operationalisations in Germany that are based on survey data, we use - following the approach in the U.S. - expert knowledge about competencies and skills - that are usually required for performing an occupation. Based on an expert database (BERUFENET of the German Federal Employment Agency), we provide an alternative task operationalisation for Germany and calculate the main task type and the composition of tasks for different occupational classifications (German Classification of Occupations 1988 and German Classification of Occupations 2010) and for different classification levels (2-digit- and 3-digit-codes). In this paper, we describe our procedure and provide first descriptive results on the validity of our new task operationalisation. " (Author's abstract, IAB-Doku) ((en)) Additional Information Data
Direct Combustion Synthesis of Silicon Carbide Nanopowder from the Elements

Direct synthesis of silicon carbide (SiC) nanopowders (size 50– 200 nm, BET~20 m 2 /g) in Si–C system is conducted in an inert atmosphere (argon) using a self-propagating high-temperature synthesis (SHS) approach. A preliminary short-term (e.g., minutes) high-energy ball milling (HEBM) of the initial mixture, which involves pure Si and C powders, is used to enhance system reactivity. Two conditions of HEBM with different force fields (17G and 90G) are applied and the results are compared. The influence of HEBM’s conditions on the microstructure of mechanically treated mixtures and combustion products is also investigated and discussed. Obtained results suggest that by changing the intensity of mechanical treatment one may prepare a completely amorphous reactive mixture containing carbon and silicon, or gradually change the ratio of (Si/C)–SiC phases and finally produce pure silicon carbide powder during the milling process. The influence of HEBM on the combustibility of the Si/C mixture possesses a critical character: the selfsustained reaction becomes feasible only after a critical time of ball milling (i.e., 10 min for 90G; 30 min for 17G). Comparison of the microstructures for as-milled and as-synthesized powders reveals that for all investigated conditions the morphologies of the as-milled reactive Si/C media are essentially the same as that for SiC combustion products. The mechanism for direct synthesis of SiC by combustion reaction is also proposed.
Development of Instrument Self-Concept Assessmen Student on Learning Mathematics in Junior High School

The difficulty of learning mathematics faced by students can be caused by several factors. Internal factors (factors from within the child itself) such as talent, interest, motivation, self-concept and others, and external factors (factors from outside the child) is the factor of the house and the surrounding environment.The goal of the research is to develop self-concept assessment instrument of students in junior high school mathematics study that is valid, reliable, practical, and know the self concept concept of students on SMP Al Amin Dukuhturi Tegal. This research is a development research with modified Borg & Gall model without dissemination and implementation stage. The validity of the instrument contents is tested by 3 experts in the field, the score given by the expert is tested using V Index, and reliability with ICC. Small-scale trials to find out valid grains tested with pearson correlation and alpha cronbach for reliability. Large-scale test of grain validity was tested with pearson correlation, construct validity with Exploratory Factor Analysis (EFA), and reliability with alpha cronbach. The results obtained 26 valid items from expert validation with reliability of 0.817. Small scale test with respondent 35, obtained 22 valid items with coefficient > 0,334, and 0,848 for reliability coefficient. Large scale test with 60 respondents obtained 22 valid items with coefficient> 0,254, construct validity of KMO value equal to 0,646 with significance 0,000, while value of MSA> 0,5 for 22 item which form 8 factor according to aspect dimension of self concept. Test of practicality, from 5 mathematics teacher respondents stated practical with score >21. Most high-caliber self-concept is obtained in small and large scale trials. Self concept assessment mathematical can be used by teachers in order to improve the learning process.
Quantum and Classical Approach Applied to the Motion of a Celestial Body in the Solar System

According to the classical mechanics the energy of a celestial body circulating in the solar system is a constant term. This energy is defined by the masses product of the larger and smaller body entering into a mutual attraction as well as the size of the major semiaxis characteristic for the corresponding Kepler orbit. A special situation concerns the planet interaction with the Sun because of a systematic decrease of the Sun mass due to the luminosity effect. The aim of the paper is to point out that even in the case of perfectly constant interacting masses the energy of the moving body should decrease when a quantum treatment of the body motion is considered. The rate of the energy decrease is extremely small, nevertheless it gives a shortening of the distance between the interacting bodies leading to a final effect of a touch of the larger body and a smaller one.
Phenotypic and genotypic population differentiation in the bivalve mollusc Arctica islandica: results from RAPD analysis

The bivalve mollusc Arctica islandica is an important commercial species with a presumed panmictic dispersal strategy, and is widely distributed throughout much of the soft sediment benthos of the North Atlantic continental shelf. Previous studies have shown that there can be gross morphologi- cal differences between populations, which has led to the suggestion that this may be reflected in geno- type. So far, only one study has examined the population genetics of this species, revealing, depending upon location, that populations are only genetically distinct at a macroscale (>1000 km), thereby supporting the assumption of panmixia. Examination of the quantitative morphological traits between 5 different populations (4 North Sea and 1 Canadian) determined that all populations could be readily identified from their unique morphologies (shapes/growth patterns) derived from 2 factors resulting from a principal components analysis. Investigation, using random amplified polymorphic DNA (RAPD) analysis, into the genetics of the populations, to indirectly assess whether the observed phenotypic differences could be related to potential differences in genotype, revealed that all populations were genetically distinct (between populations overall phiST = 0.662) from each other even at a microscale (< 25 km) (phiST = 0.719). However, no correlation between genetic distance, morphological distance and/or geographical distance, whatever metric was applied, could be obtained. It is concluded that although phenotypic differences can be used to distinguish between populations of A. islandica, it should not and cannot be used to infer genetic differences in the absence of further studies. What is interesting is that the results from the genetic analysis dispute the presumption that the dispersal patterns of A. islandica is in any shape or form panmictic. This has very important consequences for the management of the species. The results are discussed with reference to the possible mechanisms responsible for maintaining a high degree of genetic diversity between the populations that were studied.
Is There a Green Paradox?

A sufficiently rapidly rising carbon tax may increase near-term emissions compared with the case of no carbon tax. Even so, such a carbon tax path may reduce total costs related to climate change, since the tax may reduce total carbon extraction. A government cannot commit to a specific carbon tax rate in the distant future. For reasonable assumptions about expectation formation, a higher present carbon tax will reduce near-term carbon emissions. Moreover, whatever the expectations about future tax rates are, near-term emissions will decline for a sufficiently high carbon tax. However, if the near-term tax rate for some reason is set below its optimal level, increased concern for the climate may change taxes in a manner that increases near-term emissions.
The influence of one month complex spa therapy on the muscular fitness and general physical fitness of obese children

Childhood and adult obesity are associated with various health problems. Obesity in childhood is also coupled with a range of potential medical and psychosocial complications, as well as being a risk factor for increased morbidity and premature mortality in adulthood. In recent years, the prevalence of obesity among children and adolescents has risen dramatically due to unhealthy changes in lifestyle. The aim of this study was to provide some basic information about the incidence, prevention and treatment of obesity in childhood. Special emphasis was placed on physical activity and a description of spa therapy for obese children in Spa Bludov which incorporated a plan of physical activity, diet and psychological therapy. Additionally the study set out to evaluate the actual muscular and physical fitness of obese children and determine the effect of one month spa therapy on muscular fitness and general physical fitness in obese children. This study included one group of 26 obese children who had complex spa therapy and one control group of non obese children. Before and after one month spa therapy measurements of muscular fitness and general physical fitness of obese children were taken utilising the Kraus-Weber test of minimal muscular fitness and a test of general physical fitness. Outcomes for both groups were compared. It emerged that complex spa therapy has a considerable influence on physical fitness in obese children.
UvA-DARE ( Digital Academic Repository ) Drumming with dopamine neurons

Micro Electrode Arrays were used to simultaneously record spontaneous extracellular action potentials from 10-30 dopamine neurons in acute brain slices from the lateral Ventral Tegmental Area (VTA) of the rat. The spike train of an individual neuron was used to characterize the firing pattern: firing rate, firing irregularity and oscillation frequency. The functional connectivity between a pair of neurons was quantified by the Paired Phase Consistency, taking the oscillation frequency as reference. Under baseline conditions the PPC was significantly different from zero and 42 of the 386 pairs of VTA neurons showed significant coupling. 50 % of the recorded dopamine neurons were part of this functionally coupled VTA network. Raising extracellular potassium to 5 mm increased the mean firing rate of the dopamine neurons by 45 %. The same increase could be induced by bath application of 300 μm glutamate. High potassium weakened the functional connectivity, but it did not change during the glutamate application. Our findings imply that manipulating excitability has distinct and specific consequences for functional connectivity in the VTA network that cannot be directly predicted from the changes in neuronal firing rates. Functional connectivity reflects the spatial organization and synchronization of the VTA output and thus represents a unique element of the message that is sent to the mesolimbic projection area. It adds a dimension to pharmacological manipulation of the VTA micro circuit that might help to understand the pharmacological (side-) effects of e.g. anti-psychotic drugs.
Proton and heavy ion acceleration by stochastic fluctuations in the Earth's magnetotail

Abstract. Spacecraft observations show that energetic ions are found in the Earth's magnetotail, with energies ranging from tens of keV to a few hundreds of keV. In this paper we carry out test particle simulations in which protons and other ion species are injected in the Vlasov magnetic field configurations obtained by Catapano et al. (2015). These configurations represent solutions of a generalized Harris model, which well describes the observed profiles in the magnetotail. In addition, three-dimensional time-dependent stochastic electromagnetic perturbations are included in the simulation box, so that the ion acceleration process is studied while varying the equilibrium magnetic field profile and the ion species. We find that proton energies of the order of 100 keV are reached with simulation parameters typical of the Earth's magnetotail. By changing the ion mass and charge, we can study the acceleration of heavy ions such as He+ + and O+, and it is found that energies of the order of 100–200 keV are reached in a few seconds for He+ + , and about 100 keV for O+.
EFFICIENT RETRIEVAL OF DATA FROM CLOUD USING DATA PARTITIONING METHOD FOR BANKING APPLICATIONS (RBAC)

Cloud computing is a pioneering area, where abundant services are provided for storing and handling data. Though the cloud usage reduces the cost of its customers, there is a severe drawback towards its privacy. As access to the data is provided open, there is a tendency for the lack of privacy of data. The existing methods use different encryption algorithms to handle this issue. Encryption algorithms being costlier and depends on the chosen key value the method becomes less secured. Hence, in this paper a simple yet secured perturbation procedure using integer partitioning which uses the keyword itself for generating the key value. The procedure is explained with the algorithm and the results are compared with the existing method.

These quantitative aspects are important to precisely understand the impact of smoking and air pollution on public health. Smoking and air pollution have huge human cost both in suffering and in monetary terms. Healthy clean air is a global resource. International effort in controlling smoking and air pollution is fundamental in improving global public health.
Osteohistology of the Early Triassic Ichthyopterygian Reptile Utatsusaurus hataii: Implications for Early Ichthyosaur Biology

Ichthyosaurs were highly adapted to a marine lifestyle, as shown by their fish-like body shape and their assumed active swimming abilities and high metabolic rates. However, the processes of adaptation to an aquatic life in the early stages of this lineage remain poorly understood. Here, we present the first osteohistological data concerning the most basal ichthyopterygian yet known, Utatsusaurus hataii, from the Lower Triassic of Japan. The cancellous bone structure suggests adaptation to active swimming in an open marine environment. Moreover, the possible occurrence of rapidly deposited bone tissue, in a fibrolamellar complex, suggests a higher metabolic rate than in modern poikilothermic reptiles, and therefore a trend toward homeothermy. This basal ichthyosaur, with its elongate body, was already more adapted to an aquatic lifestyle than expected from its morphology, and the process of adaptation to a marine lifestyle was already well advanced by the Early Triassic.
Fluorescent colors in orchid bees (Hymenoptera: Apidae)

The presence of UV-fluorescent pigments is described for the first time in insects. The clear hairs on terga I, III and IV of Eulaema niveofasciata (Friese) are the only ones among several Euglossina species which fluoresce, supporting recent taxonomic studies which suggested that this endemic species of the Atlantic Forest domain and Eulaema bombiformis (Packard) are really different species. The UV-color pattern may have effects both on mating behavior and warning to predators.

The Relative Importance of Fuels and Weather on Fire Behavior in Subalpine Forests

Surface fire intensity (kilowatts per metre) and crown fire initiation were predicted using Rothermel's 1972 and Van Wagner's 1977 fire models with fuel data from 47 upland subalpine conifer stands varying in age from 22-258 yr and 35 yr of daily weather data (fuel moisture and wind speeds). Rothermel's intensity model was divided into a fuel component variable and weather component variable, which were then used to examine the relative roles of fuel and weather on surface fire intensity (kilowatts per metre). Similar variables were defined in the crown fire initiation model of Van Wagner. Both surface fire intensity and crown fire initiation were strongly related to the weather com- ponents and weakly related to the fuel components, due to much greater variability in weather than fuel, and stronger relationship to the fire behavior mechanisms for weather than for fuel. Fire intensity was correlated to annual area burned; large area burned years had higher fire intensity predictions than smaller area burned years. The reason for this difference was attributed directly to the weather variable frequency distribution, which was shifted towards more extreme values in years in which large areas burned. During extreme weather conditions, the relative importance of fuels diminishes since all stands achieve the threshold required to permit crown fire development. This is important since most of the area burned in subalpine forests has historically occurred during very extreme weather (i.e., drought coupled to high winds). The fire behavior relationships predicted in the models support the concept that forest fire behavior is determined primarily by weather variation among years rather than fuel variation associated with stand age.
