Awareness willingness and use of voluntary HIV testing and counseling services by students of a university in South-South Nigeria.

Background : HIV testing and counseling (HTC) is the entry point to HIV prevention, treatment, care, and support services. HTC can be voluntary or mandatory. This study aimed to determine the awareness, willingness, and use of voluntary HTC (VHTC) services by students of the Niger Delta University, Bayelsa State Nigeria. Method: A cross sectional descriptive study was conducted in June 2012 using multi-stage random sampling to select 423 students who were administered a pre-tested, structured self-administered questionnaire adapted from the UNAIDS knowledge indicator questionnaire. Information about awareness, willingness and use of VHTC services were elicited from the respondents. Epi-Info 3.5. 3 was used for data entry and analysis. Result: There was almost universal awareness of HIV (99%) by respondents but a lower proportion (78.4%) were aware of VHTC services and a much lower proportion (14.8%) knew the services were available on the university campus. Furthermore, just about a half (53.8%) had ever undergone HIV testing (Female/male: OR=1.02, 95%CI: 0.68-1.55) and only 26.5% had voluntary HTC (Female/male: OR=1.34, 95%CI: 0.75-2.40). Majority (73.8%) of all respondents expressed willingness to undergo VHTC (significantly more females than males, OR=1.67, 95%CI: 1.04-2.68). Fear of positive result (39.1%) and stigma (25.7%) were the leading demotivators for those unwilling to have VHTC. Conclusion: Despite high awareness of HIV and voluntary HTC, actual use of VHTC services was low. There is a strong need for more education of the students and indeed the community at large as this would engender a more positive attitude and increased use of available VHTC services on campus.

Plasmids of endophytic bacteria as vectors for transformation in plants

The endophytic microorganisms in general have a rich potential as producers of novel bioactive compounds, as nitrogen fixers, IAA producers, plant toxicity reducers, etc. Endophytic bacteria can also be used as vectors for transferring genes of interest to plants. These plasmid bearers have the advantage of colonizing the plant and rhizosphere with ease. In the present work, plasmids of endophytic bacteria were used as vectors instead of whole organism, for genetic studies. The advantage being transfer of plasmid encoded plant beneficial properties along with genes of interest to the plant. The present study encompasses screening of 27 medicinal plants for the endophytic colonization, in the plants. Amongst the collection of about 50 distinct endophytes, it was observed that most of these endophytes (> 50%) harbour plasmids. A bacterial isolate from Anthacephalus kadamba, Ec 14 has proven to be an ideal candidate for gene transformation in plants. It produces antibacterial proteinaceous compound that is active against plant pathogens. Antibiotic sensitivity and antibiotic peptide production were found to be plasmid born, confirmed by plasmid curing. Plasmid has restriction sites for the enzymes EcoRI, EcoRV, HindIII, SalI and BamHI.
Prawn fishery of cuddalore, northern tamilnadu coast, with special reference to long-term changes

Prawn fishery along the east coast, in general, occurs in concentrations close to major estuaries and backwaters, for which varyingsources of Information are available. Little has been known about the prevalent prawn resources along the Cauvery Delta region off Cuddalore despite large scale exploitation since the introduction of trawl fishing. The fishing grounds along Cuddalore-Portonovo coast are commonly exploited by trawlers launched from four bases; Cuddalore (D.T.), Portonovo, Devinampatnam and Pazhayar, among which observations were restricted to Cuddalore (D.T.), which was the largest with more Infrastructure facilities. The salient feature of fishery of the region has been the multiplicity of species many o fwhich being more remunerative. The combination of P.indicus and M.dobsoni in dominant and the moderate catches of M.monoceros and P.semisulcatus, form the cream of commercial fishery.
Morphological evolution of block copolymer nanocomposites submitted to extensional flows

In this work, the effect of extensional flow on the morphology of polystyrene-b-poly(ethylene-co-butylene)-b-polystyrene (SEBS) triblock copolymers and their clay-containing nanocomposites was evaluated. Four types of SEBS copolymers with different block compositions and cylindrical morphology were chosen to understand the effects of cylinder orientation and state of clay dispersion on the evolution of morphology during extensional flow. The effect of clay concentration (ranging from 2.5 to 7.5 wt. %) was also studied. The samples were subjected to extensional flow using a Sentmanat extensional rheometer attached to a rotational rheometer at Hencky strain rates varying from 0.01 to 20 s−1. Small angle X-ray scattering analysis was subsequently performed to evaluate the morphological changes caused by extensional flow. When preoriented block copolymers [SEBS-30% PS (polystyrene)] and their nanocomposites undergo elongation, the styrene cylinders and clay nanoparticles align themselves in the flow direction.
Phase equilibria of carbon dioxide and methane gas-hydrates predicted with the modified analytical S-L-V equation of state

Gas-hydrates (clathrates) are non-stoichiometric crystallized solutions of gas molecules in the metastable water lattice. Two or more components are associated without ordinary chemical union but through complete enclosure of gas molecules in a framework of water molecules linked together by hydrogen bonds. The clathrates are important in the following applications: the pipeline blockage in natural gas industry, potential energy source in the form of natural hydrates present in ocean bottom, and the CO2 separation and storage. In this study, we have modified an analytical solid-liquid-vapor equation of state (EoS) (A. Yokozeki, Fluid Phase Equil. 222-223 (2004)) to improve its ability for modeling the phase equilibria of clathrates. The EoS can predict the formation conditions for CO2- and CH4-hydrates. It will be used as an initial estimate for a more complicated hydrate model based on the fundamental EoSs for fluid phases. 1. INTRODUCTION TO GAS-HYDRATES Clathrates of natural gas, commonly called gas-hydrates, are non-stoichiometric solid solutions of a low molecular weight gas and water (1). The gas-hydrates are becoming important in many areas of human activities. Originally, the gas-hydrates were investigated due to the pipeline blockage in the natural gas industry. With increasing energy consumption, decreasing reserves of fossil fuels, and climate changes, the gas- hydrates are being investigated for two following applications: potential energy source in the form of natural hydrates present in the ocean bottom, and the carbon dioxide separation and storage (2). The clathrate is a solid crystallized solution of the gaseous component in the thermodynamically metastable water lattice. In gas-hydrates, the gas molecule, called the "guest", is situated in the cavity, referred also as the "cage" or "host", formed by a framework of water molecules linked together by hydrogen bonds. The guest-host interactions are realized through van der Waals type dispersion forces. The clathrate becomes thermodynamically stable under given temperature and pressure if a certain fraction of cavities is occupied by the guest molecules. The guest occupancy of the cavities stabilizes the empty water lattice.
EFFECT OF FERTILIZATION AND HUMIC ACID TREATMENTS ON SEEDS PRODUCTION OF PLANTAGO PSYLLIUM L.

his experiment was carried out during two consecutive seasons of 2014/2015 and 2015/2016 in the Baluza Research Station of the Desert Research Center, North Sinai Governorate, to study the effect of different rates of chemical fertilization (control without fertilization, 25, 50 and 75% of recommended rates) with different levels of humic acid (0, 2 and 4 kg/feddan) and their interaction, on the growth, seed yield, active ingredient and chemical constituents of Plantago psyllium L. plants. The treatment of chemical fertilizers gave significant effect on the plant height, number of branches per plant, the fresh and dry weights per plant, seeds yield per plant and per feddan also mucilage content and percentage per plant and per feddan. The treatment of 75% from the recommended dose gave the beast result. Treatment as well as humic acid gave significant effect for data recorded and the best treatment was obtained by adding humic acid at a level of 4 kg/feddan. The obtained results indicated that the interaction between chemical fertilizers at 75% from the recommended dose combined with addition of humic acid at 4 kg/feddan gave a significant effect for all data recorded.

Genetic similarity of Jatropha curcas accessions based on AFLP markers

The genetic relationships between accessions of Jatropha (Jatropha curcas) were determined based on AFLP marker. A set of 50 plants from 12 accessions of J. curcas was analyzed with molecular data from 164 loci generated from 17 AFLP primer combinations. Molecular variance of data was analyzed by total decomposition between and within accessions. An UPGMA dendrogram was constructed based on genetic distances estimated by Jaccard's similarity coefficient. The well-defined dendrogram showed a cophenetic value of 0.91. Groups of plants were observed in six of the 12 accessions studied with similarity of over 30 %, indicating high genetic variability. The variation among accessions was estimated to be 0.275, also indicating high variability. These results show that the genetic variability of the studied J. curcas accessions is structured according to the origin and that a greater number of populations should be sampled to increase the genetic diversity of the studied genebank.
Strategy perspectives in empirical research

This paper investigates the ontological and epistemological position implied in empirical research on strategy. Sandberg & Dall’Alba (2009) state that most empirical research is analyzed by taking on a building perspective. This statement is checked by doing a literature review. Ten articles are analyzed to find out which perspective was implied in the empirical research. Although some papers used the building mode and some used the dwelling mode, most research used a combination of both modes of strategy making. Besides concluding that a combination of both modes is used, this paper also explains why this is the case.
Tourism Led-Inflation: A case of Malaysia

The importance of the tourism industry has prevailed among developed and even developing countries. It has been perceived to be an important contribution to economic growth. However, in the proliferation of studies on inflation, information on the extent to which tourism industry able to influence inflation, is still sparse. Therefore, this study embarks on investigating tourism as a potential factor towards inflation. Data on consumer price index and the number of tourist arrival from 1986 until 2014 are used in the analysis. This study adopts a quantitative approach employing the Autoregressive Distributed Lag (ARDL) approach. Several controlled variables such as money supply, economic growth, government expenditure, and interest rate are also included. The results suggest that the tourism industry plays an important role in determining inflation in both short-and long-runs. Therefore, governments should take proactive measures in ascertaining that any expansion of the tourism industry can avert inflation.
The Promise of Nonword Repetition as a Clinical Tool

Nonword repetition requires the immediate recall of novel word forms such as woogalamic. The task mimics the learning of the phonological form of a new word as one aspect of vocabulary acquisition. Individuals with language learning diffi culties typically are poor at repeating nonwords. Children with Specifi c Language Impairment (SLI) show marked and pervasive defi cits on nonword repetition tasks; this defi cit is highly heritable and linked to chromosome 16. Even children with a history of SLI but who score in the average range on language measures continue to have diffi culty recalling novel words accurately. Nonword repetition effectively discriminates children with SLI from typically developing monolingual groups, and children learning a second language. The nonword repetition task is a simple, practical tool that can be scored online and easily adapted to the clinic environment. It is likely that the SLI impairment in nonword repetition arises in part due to defi cits in phonological knowledge and retention impairing the transfer of new phonological material to the lexicon. Intervention strategies may be aimed either at enhancing the encoding or retention of new phonological sequences.
The ozone transfer between atmosphere and vegetation. A study on Scots pine in the field

This thesis analysed the controlling processes of the transfer of ozone at the air-plant interface. Improvement in the knowledge of these processes benefits the prediction of both atmospheric removal of O3 and its impact on vegetation. This study was based on the measurement and analysis of multi-year field measurements of O3 flux to Scots pine (Pinus sylvestris L.) foliage with a shoot-scale gas-exchange enclosure system. In addition, the analyses made use of simultaneous CO2 and H2O exchange, canopy-scale O3, CO2 and H2O exchange, foliage surface wetness, and environmental variables. All data was gathered at the SMEAR measuring station (southern Finland). Enclosure gas-exchange techniques can be applied to the measure of O3 gas-exchange in the field with consideration of artefacts arising from O3 reactivity and low concentration. The O3 wall-loss was corrected with information from simultaneous and continuous measurements, and was included the mass balance formulation of O3 concentration inside the chamber. The flux of ozone to the Scots pine foliage was generated in equal proportions by stomatal and non-stomatal controlled processes. The temporal pattern of total flux was an overlap of the patterns of biological activity and presence of wetness in the environment. The stomatal uptake was estimated from models of stomatal behaviours and the non-stomatal portion of the flux was analysed further. The observed moisture enhancement was related to the presence of liquid films on the foliage surface. Theoretical simulation of the diffusive transfer at one-stoma-scale showed that O3 scavenging reactions located before or near the stomatal aperture can prevent or diminish the diffusion of ozone towards the intercellular air space of the mesophyll. The discussion covers the methodological developments of this study, the relevance of the different controlling factors of ozone flux, the partition amongst its component, and the possible mechanisms of non-stomatal uptake.
Perception of human bodies and sexual characteristics: An ERP study

ERPs were recorded to investigate the processing of the appraisal of conscious and unconscious affective stimuli as being sexual using a backward masking paradigm. Twenty heterosexual participants between 18 and 35 years old had to discriminate whether bodies were naked or dressed in a supraliminal presentation (260 ms) and in a subliminal presentation (16 ms). The results showed that during the supraliminal presentation and the subliminal presentation, the amplitude of the N190 component was significantly larger for the images of sexual characteristics versus dressed bodies over occipito-temporal electrodes. Through a segmentation procedure, a specific topographical microstate associated with the N190 component was found, though it didn’t provide further information on the processing of sexual characteristics. The neural generators responsible for the processing of sexual characteristics were located at the occipito-temporal lobe as well as the amygdala. However, there were no significant differences between images of sexual characteristics of bodies and dressed bodies for the early visual P1 component over occipito-temporal electrodes.
Effect of crack parameters on free vibrations of the Bernoulli-Euler beam

The paper presents the problem of free vibration of the cantilever Bernoulli-Euler beam with a crack. The beam along the length has a variable cross-sectional area, and the crack parameters (thickness, depth and location) undergo changes. The work includes an analytical solution of the vibration problem and the results obtained with the use of FEM and CATIA program.
Parallel process in supervision

This paper addresses the concept of parallel process and its application in clinical supervision. Parallels between therapy and supervision are examined as well as some of the key issues surrounding the use of parallel process as a supervisory intervention. Although there is a need for more investigation to explain and support this concept further, the authors would argue that parallel process interventions in supervision can enhance the supervisory process and the task of teaching and learning for both the supervisee and supervisor. A case example is provided to demonstrate the parallel process in supervision and its potential as a facilitative intervention.

The effects of ambient stratification on the crow instability and subsequent vortex reconnection

We discuss the results of direct numerical simulations of three-dimensional (3D) anti-parallel vortex pairs evolving in ambient stratification for a range of Reynolds ( Re ) and Froude ( Fr ) numbers. These results have relevance to both the study of aircraft trailing vortices, which can pose considerable hazard to following aircraft (see, e.g., Olsen et al. 1971), and the general topic of vortex reconnection, an important process in fully-developed turbulence and other complex flows (see, e.g., Rogers & Moin 1988, Melander & Hussain 1988).

Goldmann applanation tonometry versus non-contact tonometry: a comparative study -

Background: Intraocular pressure (IOP) measurement is a routine procedure in complete ophthalmologic examination and finds importance in diagnosis and monitoring of glaucoma. Goldmann applanation tonometry and non-contact tonometry, though age old, are still widely used methods of measuring IOP, especially in developing countries like India. This study was undertaken to compare IOP measured with Goldmann applanation tonometer (GAT) and non-contact tonometer (NCT) and to determine the correlation between intraocular pressure and central corneal thickness (CCT). Methods: This was a cross sectional and observational study wherein adult patients visiting a medical hospital were included. IOP measurements of one hundred and forty four eyes (glaucomatous and non-glaucomatous) were performed using GAT and NCT. The IOP values were compared in different IOP ranges using Bland Altman graph. CCT was measured and its correlation with GAT and NCT analyzed using linear regression analysis. Results: Both methods of tonometry correlated significantly with each other. The mean of paired difference between GAT and NCT was 1.24±1.38 mmHg (r=0.95, p<0.001). A positive correlation between CCT and both GAT and NCT was found with a regression of 0.35 mmHg per 10 micrometer change in corneal thickness. Conclusions: Pressure readings of GAT and NCT are comparable. Ophthalmologists need to keep in mind the variation of IOP with CCT. Suitable correction table needs to be devised when considering different CCT ranges for both methods of tonometry.
Synthesis of CuO/Co3O4 Coaxial Heterostructures for Efficient and Recycling Photodegradation

The highly efficient CuO/Co3O4 composite photocatalyst with different morphologies has been synthesized directly on Cu wire mesh by controlling the composition of cobalt-containing solid precursors via a simple hydrothermal method. The structure morphology and composition of the composite photocatalyst have been characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and UV-visible diffuse reflectance spectra. The photocatalytic result shows that the CuO/Co3O4 coaxial heterostructure is easy to recycle and exhibit enhanced photodegradation activity for methylene blue compared to single CuO nanorod arrays under full spectrum solar light irradiation. The enhanced photocatalytic efficiency of the composite could be ascribed to the synergistic effect of CuO and Co3O4. This study provides a general and effective method in the fabrication of 1D composition NRs with sound heterojunctions that show enhancement of photocatalytic performance and facility of recycling.
Assessing ‘alarm-based CN’ earthquake predictions in Italy

The quantitative assessment of the performance of earthquake prediction and/or forecast models is essential for evaluating their applicability for risk reduction purposes. Here we assess the earthquake prediction performance of the CN model applied to the Italian territory. This model has been widely publicized in Italian news media, but a careful assessment of its prediction performance is still lacking. In this paper we evaluate the results obtained so far from the CN algorithm applied to the Italian territory, by adopting widely used testing procedures and under development in the Collaboratory for the Study of Earthquake Predictability (CSEP) network. Our results show that the CN prediction performance is comparable to the prediction performance of the stationary Poisson model, that is, CN predictions do not add more to what may be expected from random chance.
