Published: September 2016

Este estudo explora um ponto de interlocução entre estudos de usuários da informação e estudos de visitante da Museologia e investiga a interação dos visitantes do Museu Itinerante Ponto UFMG com a informação. A pesquisa embasa-se no conceito de práticas informacionais enquanto um fazer etnográfico, recorrendo à observação e entrevista para coleta de dados. Os resultados apontam que inúmeros fatores influenciam a interação entre o sujeito e os elementos do museu. Muitas vezes, os relatos dos entrevistados contradizem as observações, e a explicação para tal contradição está num misto de fatores, perpassando pela concepção dos sujeitos sobre museus e o nível de preocupação deles quanto à imagem que querem transmitir de si. Concluímos que a observação participante, aliada à entrevista, mostrou-se apropriada para desvelar os significados da experiência de visita, possibilitando-nos captar não apenas o que os visitantes dizem que fazem, mas também o que eles realmente fazem e o que pensam sobre o que fazem.

Authors: Spudeit Daniela , Cunha Miriam Vieira da
Published: September 2016

Este estudo objetiva analisar o modelo de profissão construído pelos bibliotecários durante o processo de socialização; identificar as formas de inserção desse profissional no mundo do trabalho, o perfil e os motivos que os levaram à escolha da profissão para compreender como a socialização contribui na construção da identidade. A fundamentação teórica para o estudo foi baseada, principalmente, em Hughes (1958), Dubar (2005), Berger e Luckman (2009). Os resultados evidenciaram que o interesse pela profissão foi despertado pelas aptidões, pelo gosto da leitura e pela influência que esses profissionais tiveram de familiares e de amigos que conheciam a profissão. Demonstram que a identidade foi construída por meio das relações pessoais, profissionais e no ambiente de trabalho, o que facilitou a sua inserção profissional. Em relação ao modelo profissional, a pesquisa mostrou que os bibliotecários passam por várias fases, como a imersão na cultura profissional, o choque de realidade entre o modelo ideal e o real para, em seguida, reconstruir seu modelo com base na imagem idealizada e na imagem real de profissão. Conclui-se que a identidade profissional está sempre se construindo, de acordo com as vivências e experiências do meio em que esse profissional está inserido e das mudanças no mundo profissional.

Authors: Jenner Eric , Jenner Lynne W. , Walsh Sarah , Demby Hilary , Gregory Alethia , Davis Erin
Published: September 2016

Objectives. To replicate an evidence-based HIV risk reduction program and assess its impact on 2 behavioral outcomes—inconsistency of condom use and frequency of sex—6 months after the program.

Methods. The study was an individual-level randomized controlled trial in which we randomly assigned 850 youths (aged 14–18 years) to 1 of 2 conditions. The treatment (Becoming a Responsible Teen) is a group-level sociocognitive and skills training sexual education course; the control is a general health intervention that includes the same initial informational component as the treatment. Participants were recruited over 3 summers (2012–2014) from a summer employment program in New Orleans, Louisiana, that serves primarily African American adolescents.

Results. Six months after program exposure, we found no statistically significant difference between treatment and control group members’ self-reported inconsistency of condom use or frequency of sex (P > .05).

Conclusions. Although previous evidence has indicated that this particular program can be effective, this study’s findings indicate that it was not effective in this setting with this specific population. Results should provide an incentive to learn why the intervention works in some cases and what conditions are necessary for causal impacts.

Authors: Gelfond Jonathan , Dierschke Nicole , Lowe Diana , Plastino Kristen
Published: September 2016

Objectives. To assess whether a sexual health education intervention reduces pregnancy rates in high school students.

Methods. We performed a secondary analysis of a 3-year quasi-experimental study performed in South Texas from 2011 to 2015 in which 1437 students without a history of pregnancy at baseline were surveyed each fall and spring. Potentially confounding risk factors considered included sexual behaviors, intentions, and demographics. The outcome measure was self-reported pregnancy status for male and female students. We performed analyses for male and female students using separate discrete time-to-event models.

Results. We found no difference in pregnancy rates between intervention and comparison students within the first 3 years of high school. Female and male students in the intervention groups had pregnancy hazard ratios of, respectively, 1.62 (95% CI = 0.9, 2.61; P = .1) and 0.78 (95% CI = 0.44, 1.48; P = .4) relative to the comparison groups.

Conclusions. The educational intervention had no impact on the pregnancy rate. Social media tools in pregnancy prevention programs should be adaptive to new technologies and rapidly changing adolescent preferences for these services.

Objectives. To evaluate the Teen Outreach Program, a pregnancy prevention program, in 2 community-based settings.

Methods. We evaluated the Teen Outreach Program, a 9-month positive youth development program, in 3 cohorts of youths from 2012 to 2015 in 2 states. In Louisiana, 7 agencies participated in an individualized randomized controlled trial, with youths randomly assigned to a treatment or control condition. Fourteen agencies in Rochester, New York, participated in a cluster randomized controlled trial.

Results. We found no differences between the intervention and control youths on delay of sexual onset in Louisiana (adjusted odds ratio [AOR] = 0.80; 95% confidence interval [CI] = 0.62, 1.03) or in Rochester, New York (AOR = 0.89; 95% CI = 0.45, 1.77), or for sex with no effective means of birth control (Louisiana, AOR = 1.18; 95% CI = 0.78, 1.78; Rochester, AOR = 0.41; 95% CI = 0.13, 1.27) after controlling for relevant covariates.

Conclusions. We found no short-term effects for the offer of the intervention. Research might be needed for the long-term and intermediate impacts of youth development programs on these and other adolescent risk behaviors.

Authors: Piotrowski Z. Harry , Hedeker Donald
Published: September 2016

Objectives. To investigate the impact of Be the Exception, a newly developed program to delay onset of sexual behaviors, in a White, rural population.

Methods. A cluster randomized controlled trial in northwestern Indiana (14 schools, 1776 students, 2011–2015) compared an intervention (5 group sessions and multimedia assembly) with a no-intervention group; both continued usual standard health education. Multilevel mixed-effects logistic regressions with 1455 students measured long-term outcomes 12 months after baseline questionnaire.

Results. Intervention group students reported ever having had sexual intercourse and sexual intercourse in past 3 months significantly less often than did the comparison group (1.91% vs 6.29% and 1.09% vs 4.26%, respectively). No statistical differences were observed for reported sexual intercourse in past 3 months with risky behavior (1.23% vs 2.24%), without condom use (1.04% vs 1.73%), or without birth control (1.00% vs 1.53%). Cumulatively, intervention group students significantly more often reported no activity, holding hands, hugging and kissing and less often reported touching above and below the waist, other sex, or sexual intercourse.

Conclusions. Be the Exception is effective in delaying the onset of sexual behavior among rural middle school students.
Estimates of Stress-Dependent Properties in Tight Reservoirs: Their Use With Core and Drill-Cuttings Data
Authors: Lopez Jimenez Bruno A. , Piedrahita Jaime , Aguilera Roberto
Published: September 2016

The objective of this paper is to present a methodology with drill cuttings for making estimates of porosity, permeability, and compressibility as a function of confining pressures in tight formations.

An easy-to-use stress-dependent permeability correlation is developed by comparing results from experimental work including hysteresis at various combinations of overburden and pore pressures in vertical and horizontal core plugs, and permeabilities determined in the laboratory from drill cuttings. On the other hand, stress-dependent porosity and compressibility correlations with respect to permeability as a function of net confining stress (NCS) are also introduced. The work is important because of the presence of stress-dependent slot and/or microfracture porosities and permeabilities in tight formations that can significantly affect reservoir performance and forecasting.

Recent work has shown that drill cuttings can be used quantitatively for complete petrophysical evaluation and rock-mechanical-properties estimation (Olusola and Aguilera 2013; Ortega and Aguilera 2014). The methods have been shown to be useful in those instances in which cores and specialized well logs are scarce. Porosity and permeability values obtained from the aforementioned works are extended in this paper to quantitative evaluation of stress-dependent properties.

It is concluded that drill cuttings are important direct sources of information that can be used for developing estimates of stress-dependent petrophysical properties particularly in those cases in which cores and specialized logs are scarce or not available. The methodology and stress-dependent-permeability, -porosity, and -compressibility correlations are presented in detail, as well as a practical application for the case of drill cuttings. Although the main and novel contribution is the development of easy-to-use correlations for stress-dependent tight reservoirs with drill cuttings, the correlations can obviously be used if only plug data are available.

Published: September 2016

The article is devoted to analysis of the errors that occur when acoustic diagnostics of stress state for shaped profiles of metal structures. The analysis of methods for acoustic diagnostics of stressed state of shaped profiles was conducted using mirror-shadow method and areas, causing the occurrence of errors, were revealed. The analysis of tool, methodical and subjective errors that accompany acoustic diagnostics of stress state of shaped profile allowed offering recommendations for their reduction and increasing the reliability of diagnostics results. The necessity of reducing the total error for determining the stress state caused by factors accompanying acoustic diagnostics of shaped profiles was shown. Application of automation during the acoustic diagnostics of stress state for shaped profiles of metal structures was proposed. This will significantly increase the reliability of the data by reducing human intervention in the process of measurement and processing results. Technical and methodological solutions were proposed that will reduce the impact of the total error on the result of acoustic diagnostics of stress state for shaped profiles using the mirror-shadow scanning method.

Published: September 2016

In recent years, Horizontal Directional Drilling has been the first choice in trenchless engineering of pipeline crossing for its strong environmental adaptability, high efficiency and low cost. In order to reduce the resistance force and avoid pipeline damage in construction, the angle formed by the pipeline axis and hole axis should be lessened when the pipeline is lifted to a height. However, the stress status of the pipeline is very complex during the lifting process. Hence the research of pipeline lifting process is great importance for pipeline safety. In this paper, a finite element model is established to uncover the stress variety law of pipeline during lifting process. And then its reliability was verified by the experimental method. At last, the results of engineering experiment show that the finite element model which is credible can be used to reveal the stress variety law of the pipeline during the lifting process.
Effects of thermal aging of laminated rubber bearing on seismic performance of bridges
Authors: Oh Ju , Kim Jin Ho , Yi Hwa Cho
Published: September 2016

The dynamic characteristics of laminated rubber bearings, which are used as isolator, are dependent on the main rubber's dynamic behaviors and nonlinear properties. Rubber materials tend to undergo an aging process under the influence of mechanical or environmental factors, so they inevitably end up facing damage. A main cause of aging like this is known to be oxidization, which occurs through the heat of reaction at high temperatures. Accordingly, in this study an accelerated thermal aging test was carried out in order to compare the characteristic values of the bearings before and after thermal aging occurs. As a result of this experiment, it was found that a thermal aging phenomenon could have some effects on shear stiffness, energy absorption, and equivalent damping coefficients of the bearings. Furthermore, a deterioration in the dynamic properties of the laminated rubber bearings caused by the thermal aging was applied to an actual bridge and then the effects of such thermal aging on the seismic performance of the bridge were also compared and analyzed based on numerical analysis. As a result of this analysis, it was found that the changes in the basic properties of the natural rubber bearings caused by the thermal aging bring only a minor effect on the seismic performance of bridges.

Authors: Bilgic Hasan Huseyin , Sen Muhammed Arif , Kalyoncu Mete
Published: September 2016

Stabilizing of an inverted pendulum (IP) system is a main problem for researchers working on control theory. Balancing of an inverted pendulum system is one of the major benchmark problems in the control system community. This paper presents optimal tuning of linear quadratic regulator (LQR) controller with The Bees Algorithm (BA) for a linear inverted pendulum. In this paper, a metaheuristic approach which is a nature-inspired search method that mimics the foraging behavior of honey bees is used for design of LQR controller to obtain optimal performance. In LQR controller design, state (Q) and control (R) weighting matrices are basic parameters of LQR which are tuning by designer using trial and error method in usually. The Bees Algorithm optimizes the weighting matrices of the LQR controller so that it can move the cart to a desired position with the minimum change in pendulum’s angle from vertically upright position during the movement. The tuned LQR controller is benchmarked on the linear inverted pendulum experimental device (IP02) that is manufactured by QUANSER Company. After description of the system and The Bees Algorithm, the paper gives the experimental results obtained from the IP02 system to demonstrating the efficiency of the tuning of the LQR controller. Simulation and experimental results are given graphically to show the success of controller. As a result of the paper, the performance of LQR controller shows the effectiveness of The Bees Algorithm which is a diversity method for provide an efficient solution to conventional trial and error design approach.

Authors: Zhu Lida , Ding Yang , Liu Changfu , Xu Zhiwei
Published: September 2016

High-speed milling of thin-walled part is a common application for aerospace industry, automotive, computer hardware and bioengineering industries. Aiming at the small-stiffness frequency response characteristics of thin-walled parts, the dynamic model and critical condition of stability was proposed by the relative transfer functions between cutter subsystem and thin-walled part subsystem in this paper. The stability critical domain was predicted by semi-discretization (SD) method based on the dynamic behavior of the multi-DOF system. It can be shown that the chatter condition in high-speed milling is closely related to both cutter speed and depth of cut, besides cutter geometry, engagement conditions, relative frequency response function, material property of thin-walled part and so on. This conclusion provides a theoretical foundation and reference for the milling mechanism research.

Authors: Liu Zhimin , Sun Hanxu , Li Yansheng , Jia Qingxuan , Chu Ming
Published: September 2016

This paper addresses the point stabilization problem for the underwater spherical roving robot (BYSQ-3) in the horizontal plane. The finite-time stable control laws are adopted to steer the robot to the origin fast, accurately and reliably. Firstly, the inner structure and operational principle of the robot is described and the kinematic and dynamic equations are established. Secondly, the diffeomorphism transformation and change of inputs are introduced to decouple the multivariable coupling system into two subsystems. The second subsystem consists of two double integrator systems. The finite-time controller is introduced to ensure part states converge to zero in finite time. Then, the other states are steered to the origin using the same method. Thirdly, the design process has no virtual input and the stability analysis is simple, the controller designed is easy for engineering implementation. The simulation and experiment results are presented to validate the shorter convergence time and better stability character of the controller.
Performance and dynamic characteristics of a multi stages vertical axis wind turbine
Authors: Attia El Arabi , Saber Hesham , El Gamal Hassan
Published: September 2016

Vertical axis wind turbines (VAWTs) are used to convert wind energy to mechanical output or electricity. Vertical axis wind turbines are favorable at buildings as it can receive wind from any direction, have a design that can be integrated simply with building architecture and they have better response in turbulent wind flow which is common in urban areas. Using a calculation code based on the Double Multiple Stream Tube theory, symmetrical straight-bladed NACA0012 wind turbine performance was evaluated. The induction factor for both upwind and downwind zone is determined with the aid of a root-finding algorithm. This numerical analysis highlighted how turbine performance is strongly influenced by the wind speed (Reynolds number) and rotor solidity (turbine radius and blade chord length). Also a dimensional analysis is introduced and is to be considered in such a way to generalize the design for different turbine specifications. One of the qualities provided by dimensional analysis is that geometrically similar turbines will produce the same non-dimensional results. This allows one to make comparison between different sizes wind turbines in terms of power output and other related variables. One of the main problems affecting the turbine performance and dynamics is the torque ripple phenomena. So in this paper a turbine design configuration is introduced in order to decrease the turbine torque fluctuation. This design is carried out by constructing more similar turbine units (stages) on the vertical axis on top of each other with different orientation phase angles. The results showed that using even number of turbine assembly is better than odd number to avoid torque fluctuation and mechanical vibrations acting on the turbine. Also it is preferred to use four turbine stages as the eight stages will have no sensible effect on decreasing the torque fluctuation.
Characteristics and sources analysis of riverine chromophoric dissolved organic matter in Liaohe River, China
Authors: Shao Tiantian , Song Kaishan , Jacinthe Pierre-Andre , Du Jia , Zhao Ying , Ding Zhi , Guan Ying , Bai Zhang
Published: September 2016

Chromophoric dissolved organic matter (CDOM) in riverine systems can be affected by environmental conditions and land-use, and thus could provide important information regarding human activities in surrounding landscapes. The optical properties of water samples collected at 42 locations across the Liaohe River (LHR, China) watershed were examined using UV-Vis and fluorescence spectroscopy to determine CDOM characteristics, composition and sources. Total nitrogen (TN) and total phosphorus (TP) concentrations at all sampling sites exceeded the GB3838-2002 (national quality standards for surface waters, China) standard for Class V waters of 2.0 mg N/L and 0.4 mg P/L respectively, while trophic state index (TSIM) indicated that all the sites investigated were mesotrophic, 64% of which were eutrophic at the same time. Redundancy analysis showed that total suspended matter (TSM), dissolved organic carbon (DOC), and turbidity had a strong correlation with CDOM, while the other parameters (Chl a, TN, TP and TSIM) exhibited weak correlations with CDOM absorption. High spectral slope values and low SUVA254 (the specific UV absorption) values indicated that CDOM in the LHR was primarily comprised of low molecular weight organic substances. Analysis of excitation-emission matrices contour plots showed that CDOM in water samples collected from upstream locations exhibited fulvic-acid-like characteristics whereas protein-like substances were most likely predominant in samples collected in estuarine areas and downstream from large cities. These patterns were interpreted as indicative of water pollution from urban and industrial activities in several downstream sections of the LHR watershed.

Authors: Rubin-Oliveira Marlize , Dal Pai Franco Maria Estela
Published: September 2016

O objetivo central deste artigo foi analisar programas de pós-graduação interdisciplinares, buscando captar especificidades dos contextos e pretextos dos programas confrontados. O locus do estudo foram oito programas de pós-graduação (stricto sensu) interdisciplinares reconhecidos e recomendados pela Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes), que têm como princípio o diálogo entre Ciências Humanas e da Natureza e um programa da University of Arizona (U of A), dos Estados Unidos. As análises realizadas identificaram uma relação estreita entre movimentos internacionais de repensar a ciência moderna e a gênese dos programas. Os programas são compreendidos como parte do movimento crescente da ciência que busca repensar a fragmentação e a dualidade, inclusive na direção de legitimar outros espaços de poder e prestígio e rever a organização de áreas do conhecimento historicamente constituídas.

The objective of this literature review, describe the aspects related to the quality of beef. In general, a number of factors such as management in the creation, transport, pre-slaughter management in the refrigerator is directly related to the quality of meat. The pre-slaughter cattle management is widely studied and includes concrete results in the scientific literature that it significantly influences the quality of meat and the use of housing. Usually the losses are related to injuries, but no other loss mode which is caused by the stress experienced by cattle during handling, property or poorly planned abattoirs, which raises the pH of the meat and reduces its useful life. Good management throughout the breeding system is reflected in the quality of the meat. Aggregating quality, even through some identifiable characteristics, promotes the differentiation of the product. Thus, as the damage caused by inadequate management, differentiation gains through animal welfare practices can be shared by all the productive chain agents.

Auditors' Constraining Effect on Tax Noncompliance at Different Book-Tax Conformity Levels in a Transition Economy
Authors: Chan K. Hung , Luo Rebecca , Mo Phyllis Lai Lan
Published: September 2016

This study examines how differential auditor quality can affect clients' tax noncompliance at different book-tax conformity levels. Overall, we find that high-quality auditors are associated with client firms' better tax compliance. Specifically, high-quality auditors are effective in constraining book-tax-conforming noncompliance because of the direct linkage between financial and tax reporting for such noncompliance at both the higher and the lower conformity periods. In contrast, high-quality auditors' constraining effect on book-tax-difference noncompliance is significant only in the lower conformity period when there are more opportunities for reporting irregularities. Furthermore, firms that switch from a low- to a high-quality auditor have better tax compliance after the switch. This study contributes to the literature by providing evidence that high-quality auditors not only can constrain clients' earnings management, but can also constrain tax noncompliance.

Water Sorption and Solubility of Luting Agents Used Under Ceramic Laminates With Different Degrees of Translucency

Purpose: The aim of this study was to evaluate the effect of low-thickness ceramic laminate translucency on water sorption and solubility in resin luting agents.

Methods and Materials: Ceramic slides (15×0.7 mm) were generated using lithium disilicate (IPS e.max Press, Ivoclar-Vivadent, Schaan, Liechtenstein) that were A1 in color and had decreasing degrees of translucency (high, medium, and low). A slide of transparent glass of similar size was used as the control. Under each slide, 15 specimens (8×0.5 mm) of differing composite materials from the same manufacturer (3M ESPE Dental Products, St Paul, MN, USA) were prepared (n=5): light-cured resin cement (RelyX Veneer); dual-cured resin cement (RelyX ARC); and flowable composite (Z350XT Flow). To evaluate the loss or gain of mass, the specimens were dried until a constant mass was reached. Then, they were immersed in water for seven days and weighed immediately following removal from water. Subsequently, the specimens were dried again until a constant mass was obtained. The mass measurements were used to calculate the water sorption and solubility. Statistical analyses were carried out using a two-way analysis of variance and the Tukey test.

Results: Under the high-translucency ceramic slides, all of the luting agents showed similar performance regarding water sorption; the flowable composite resin and the light-cured resin cement had the lowest solubility values. Under the medium- and low-translucency surfaces, the dual-cured resin cement and the flowable composite resin showed better performance with respect to water sorption and solubility.

Conclusions: In the case of high-translucency laminates, luting agents with different activation methods might be used. However, even in thin sections, decreasing the translucency of the laminate led to significant loss of light penetration, indicating a decreased likelihood of the physical activation of the resin cement.

The present study aimed to characterize the pattern and volume of polymerization shrinkage of flowable resin composites, including one conventional, two bulk fill, and one self-adhesive. Standardized class I preparations (2.5 mm depth × 4 mm length × 4 mm wide) were performed in 24 caries-free human third molars that were randomly divided in four groups, according to the resin composite and adhesive system used: group 1 = Permaflo + Peak Universal Bond (PP); group 2 = Filtek Bulk Fill + Scotchbond Universal (FS); group 3 = Surefil SDR + XP Bond (SX); and group 4 = Vertise flow self-adhering (VE) (n=6). Each tooth was scanned three times using a microcomputed tomography (μCT) apparatus. The first scan was done after the cavity preparation, the second after cavity filling with the flowable resin composite before curing, and the third after it was cured. The μCT images were imported into three-dimensional rendering software, and volumetric polymerization shrinkage percentage was calculated for each sample. Data were submitted to one-way analysis of variance and post hoc comparisons. No significant difference was observed among PP, FS, and VE. SX bulk fill resin composite presented the lowest values of volumetric shrinkage. Shrinkage was mostly observed along the occlusal surface and part of the pulpal floor. In conclusion, polymerization shrinkage outcomes in a 2.5-mm deep class I cavity were material dependent, although most materials did not differ. The location of shrinkage was mainly at the occlusal surface.
A Conservative Technique for Repairing Class IV Composite Restorations
Authors: Ruschel VC , Stolf SC , Shibata S , Baratieri LN
Published: September 2016

Composite resin may make a restoration noticeable as time passes, on account of its color instability. The repair technique is a minimally invasive treatment for class IV composite resin restorations that show unsatisfactory coloration. Thus, the objective of the present article was to report a clinical case involving a conservative technique used for repairing a class IV composite resin restoration in the left maxillary central incisor and the replacement of a class IV restoration in the right maxillary central incisor.
Seven-Step Framework for Critical Analysis and Its Application in the Field of Physical Therapy

Published: September 2016

Critical analysis (or the ability to recognize taken-for-granted assumptions and their effects) is a skill that requires teaching and practice. The purpose of this article is to introduce a framework for critically analyzing assumptions within physical therapy and illustrate its utility through application to 2 examples: a physical therapy clinic logo and an outcome measure for health-related quality of life (HRQOL). This 7-step framework for critical analysis was created for a pilot project to develop reflexivity among senior physical therapist students and further developed through an iterative process of reflecting on its utility for advancing the field of physical therapy. The 7-step framework is an iterative process involving a cascade of 7 steps: (1) name the specific aspect of practice being analyzed, (2) identify the intended purposes of this aspect of practice, (3) uncover the assumptions that support these intended purposes, (4) identify who benefits, (5) identify who is disadvantaged, (6) link these specific ideas to society-level patterns, and (7) conceive of alternatives that mitigate actual or potential harms. It is emphasized that being theoretically critical does not equate to being negative. Rather, the word “critical” is used in the sense of thinking deeply and carefully about the intended and unintended consequences of actions (including common professional practices, ways of speaking, and visual representations) in order to reflect on and mature the field of physical therapy. The purpose of critical analysis is to invite and promote dialogue that assists physical therapist clinicians, researchers, and students to arrive at new insights about the impacts of their day-to-day actions.
Educational Status and Postnatal Care Practices among Dalit and Janajati Women of Nepal
Authors: Baral Om Prasad
Published: September 2016

This paper deals with educational status and postnatal care practices and the association of educational status and postnatal care practices of Dalit and Janajati women of Nepal. The result shows that literacy rate of respondents was 51.4 percent which is lower than the national level women literary rate 57.4 percent of Nepal. PNC (Postnatal Care) visit of Dalits and Janajatis women who visited three times during postnatal period were found to be 36 percent in survey area. PNC visit of respondents is less frequent than the national level PNC checkup (55 percent). Thus, it is recommended that Dalit and Janjati mothers who come for antenatal check up should be provided with adequate information about availability of safe delivery incentive, incentive for postnatal checkup and free health services provided by government of Nepal.Academic Voices Vol.5 2015: 22-27
Antimony(V) as Acceptors
Authors: Yadav Ram Nath Prasad
Published: September 2016

Lewis acidity of antimony(V) pentahalides and their organo substituted derivatives is well known. SbX5 acts as a strong acceptor towards halide ion as compared to antimony trihalide due to presence of two more electronegative halogen atoms in antimony pentahalide makes it better acceptor. Hexacoordinated organoantimony(V) complexes including chelating ligands are also known and hexacoordination and heptacoordination environment have been suggested for such compounds. The substitution of hydrocarbon groups bound to antimony by trifluoromethyl or pentafluorophenyl groups enhances the Lewis acidity of antimony facilitating the formation of neutral adducts. Such properties have mainly been investigated with organoantimoy(V) halides. As expected successive replacement of an organic group by halogen atom increases acceptor strength of antimony(V) compounds.Academic Voices Vol.5 2015: 34-39
