Authors: Khaki Saeideh , Torkan Hajar , Sebghatollahi Vahid
Published: June 2019

Background: Irritable Bowel Syndrome (IBS) is a serious syndrome, which damages people’s psychological, communicative, social, and emotional lives. Therefore, the present study was conducted to compare integrative self-knowledge and impulsivity in patients with Irritable IBS and healthy individuals.
Methods: This case-control study was conducted on patients with IBS referring to gastroenterologists and healthy individuals in the city of Isfahan in 2018. The sample size included 150 patients with IBS and 150 healthy people in Isfahan selected using non-random convenient sampling method. The integrative self-knowledge and impulsivity questionnaires were applied to collect the information. After collecting the questionnaires and extracting the raw data, SPSS23 software was used and t-test was run to analyze the data.
Results: A significant difference was observed between patients with IBS and healthy participants with regard to integrative self-knowledge and impulsivity (P-value < 0.001), so that people with IBS had lower integrative self-knowledge and higher impulsivity in comparison with the healthy individuals.
Conclusion: According to the findings, people with IBS had lower integrative self-knowledge and higher impulsivity due to their therapeutic and psychological involvement in the disease. So, third-wave psychological treatments such as mindfulness treatment and positivist psychotherapy are required in this area.

Published: June 2019

Introdution: Studies have shown that plant compounds have significant anticancer effects that if the challenges of using them are resolved, can be the successor to the synthetic compounds commonly used in cancer therapy. Therefore, in this study, the liposomal nano- carriers containing Nepeta persica extract have been investigated in order to improve the physicochemical characteristics and evaluation of its antitumor properties.
Methods: The present study was an experimental study. Liposomal vesicles were prepared using SPC, cholesterol and PEG by thin-film method and the Nepeta persica extract was loaded into the liposomes. Their physicochemical characteristics were evaluated using Zeta Sizer, FTIR, SEM, and the release pattern of the extract was calculated at 37 oC and 42 oC. At the end, the toxicity of this nano-carriers containing the extract on the MCF-7 cell line of breast cancer has been studied.
Results: The results of the study showed that the nano-carriers containing the extract had an encapsulation efficiency of 67/11±5/74%, size of 116/9 nm, and -13.24 ± 1.01mV zeta potential, spherical morphology and controlled release. Also, the results of the toxicity of this nano-carrier containing the extract indicate that the liposomal extract has a higher toxicity to the MCF-7 cell line than the free extract..
Conclusion The results of this study show that nano-liposomes containing Nepeta persica extract, mean while having appropriate physiochemical properties, reduce the survival of breast cancer cells compared to non-liposomal extracts, and thus can be a good carriers for delivery of Nepeta persica extract to breast cancer cell.
FRAMING THE SOCIAL RESPONSIBILITY ROLE OF ISLAMIC FINANCIAL INSTITUTIONS WITHIN A THREE-SECTOR ECONOMIC MODEL
Authors: Barom Mohd Nizam
Published: June 2019

Purpose: This paper examines and reflects the ongoing debate on the social responsibility role of Islamic financial institutions (IFIs) in the light of the literature in the area of third sector and three-sector economic model. Subsequently, it seeks to develop a framework that can be used to conceptualise the potential interaction between the different sectors in the economy in relation to social welfare issues and locate the social responsibility role of IFIs within this framework.  

 Methodology: The paper uses an integrative analysis of Islamic finance and third sector literature, particularly on the American and European conceptions of the interactions between the three main sectors in the economy, i.e. public, private and ‘third’ sectors.

Results: The paper develops a modified circular flow of income and expenditure model as a basis for the integrative framework for social welfare provision within a three-sector economic model. Subsequently, it locates the social responsibility role of IFIs within this framework with the understanding that social welfare burden is a collective responsibility and therefore shared among the various potential welfare providers in the economy.

 Implications: The integrative framework of social welfare provision within a three-sector economic model as conceptualised in this paper highlights a multi-institutional approach towards promoting socio-economic justice and society's well-being in an Islamic economy, and hence provides a proper and reasonable context for social responsibility roles expected of IFIs.

Published: June 2019

Present investigation was conducted in 31 groundnut accessions to assess genetic divergence, characters association involving 13 quantitative characters and path coefficients in order to identify superior accessions exhibiting higher genetic diversity. Number of pods/plant, secondary branches, kernel width, and pod yield displayed a higher level of coefficient of variation both at phenotypic and genotypic level. Genetic advance with higher heritability indicated preponderance of additive variance for pod length, pod yield, and number of pods/plant. Number of secondary branches, kernel width, pod length, and number of pods/plant revealed significant positive correlation with pod yield. Path coefficient analysis revealed exertion of high positive direct effects on pod yield through pod length, kernel width and number of pods/plant. Cluster analysis exhibited substantial diversity among 31 accessions forming 13 clusters. Two clusters [X (two accessions) and XII (one accession)] showed the largest distance, which suggests hybridization between these accessions to achieve high level of heterosis for further exploitation. Five accessions viz., TAG-24, TG-69, ICGV-02005, TG-73 and TG-80 were identified as the most divergent for future use.

Characterization of Photophysical Properties of D−π−A−π−D Type Diketopyrrolopyrrole Based Molecules for Organic Light-Emitting diodes and Organic Solar Cells
Authors: Jin Ruifa , Zhang Xiaofei , Xiao Wenmin
Published: June 2019

A series of D–π–A diketopyrrolopyrrole (DPP)-based small molecules have been designed for organic light-emitting diodes (OLEDs) and organic solar cells (OSCs) applications. Appling the PBE0/6-31G(d,p) method, the ground state geometry and relevant electronic properties were investigated. The first excited singlet state geometry and the absorption and fluorescent spectra were simulated at the TD-PBE0/6-31G(d,p) level. The calculated results reveal that the photophysical properties are affected through the introduction of different end groups. Furthermore, the electronic transitions corresponding to absorption and emission exhibit intramolecular charge transfer feature. It was disclosed that the designed molecules act not only as luminescent for OLEDs, but also donor materials in OSCs. Moreover, they also can be used as potential electron transfer materials using for OLEDs and OSCs.

Authors: Li Huajing , Duan Na , Zhang Qing , Shao Yuan
Published: June 2019

Background: Head and neck cancer (HNC) is the sixth most frequent malignancy in the world. Interleukin 4 (IL-4) has been proved to be closely related to the occurrence and development of cancer. The objective of this research was to assess the association of IL-4 genetic polymorphisms with HNC risk in Chinese Han population.
Methods: Six single nucleotide polymorphisms (SNPs) of IL-4 gene were successfully genotyped using Agena MassARRY in 535 HNC patients and 538 healthy controls. Under multiple genetic models, stratification analysis and haplotype analysis, odds ratio (OR) and 95% confidence interval (CI) were calculated to assess the association between SNPs and HNC risk.
Results: The polymorphism, rs2243250, in the IL-4 gene was significantly associated with an increased HNC risk in the allele model (P < 0.05). In the genetic model, the polymorphisms rs2243250, rs2243267 and rs2243270 in IL-4 gene conferred an increased risk of HNC (P < 0.05). Gender stratification analysis showed that in males, rs2243250, rs2243267, rs2243270 and rs2243289 were associated with an increased risk of HNC (P < 0.05), while rs2243283 was associated with a decreased risk of HNC in males (P < 0.05). Besides, we have not found any association between six SNPs in IL-4 gene and HNC risk in females. Further haplotype analysis revealed that the haplotype CTGAC was significantly associated with a decreased risk of HNC.
Conclusion: This study provides an evidence for polymorphism of IL-4 gene associated with the development of HNC in the Chinese Han population.

Published: June 2019

Background: Hepatitis B surface antigen (HBsAg) positive leads to pregnancy outcomes and effects on offspring BMI z-score remains unclear in China. We are aim to explore if there is an association among HBsAg positive, BMI z-score, and pregnancy outcomes.
Methods: We extracted the characteristic information and pregnancy outcomes of pregnant women, and BMI z-score from 1 to 3 years in offspring from the Medical Birth Registry of Xiamen that registered between 1 March 2011 and 30 March 2018.
Results: Pregnant women with HBsAg positive had a higher risk of gestational diabetes mellitus (GDM) (1.128, 1.032-1.232), and cesarean delivery (1.116, 1.026-1.213). Interestingly, there is no difference between HBsAg positive and offspring BMI z-score (all P > 0.05). Additionally, the GDM women with HBsAg positive had higher incidence of low-for-gestation age (LGA), preterm birth, and cesarean delivery (22.95%, 9.48%, and 47.88%, respectively) (all P < 0.001).
Conclusions: HBsAg positive may be a risk factor of GDM and cesarean delivery. However, HBsAg positive has no effects on offspring BMI z-score. Therefore, women should perform GDM and HBsAg screening before or during pregnancy. As well, a larger follow-up population study should be performed to confirm the association between HBsAg positive and offspring BMI z-score.
Challenges of WASH in remote Australian Indigenous communities
Authors: Hall Nina Lansbury
Published: June 2019

Health and well-being are influenced by access and quality to safe drinking water, wastewater treatment, and hygiene practices and settings. This is recognised in the United Nations' Sustainable Development Goals for water and health. As a signatory to the UN Goals, Australia has a commitment to ensure the access and quality of these resources is attained for all, including Indigenous Australians living in remote communities. This research sought to identify the status of water, sanitation and hygiene services within remote communities on mainland Australia. Interviews were conducted with representatives of organisations providing water, sanitation and/or hygiene to communities. The quality and access of WASH services in remote Indigenous communities were revealed in this research as lacking at times in many communities. The qualitative results indicate that drinking water supplies can be contaminated by microbes or naturally occurring chemicals, wastewater treatment can be poorly maintained with irregular monitoring, and the health of residents is negatively impacted by crowding in houses, which affects residents' ability to maintain healthy hygiene levels of people, clothing, bedding and infrastructure. Effective responses require a collaborative and systemic approach by the respective government agencies responsible that effectively partner with – and adequately fund – Indigenous communities to provide options that are ‘fit for purpose, place and people’.

A company is established to raise the value of the firm by maximizing profit and shareholder’s wealth. In the capital market, firm value is reflected in the stock price. To raise a firm value, needed to investigate the determinant of firm value. So, this research is aimed to determine the effect of free cash flow on firm value with dividend payout and investment opportunity set as mediator. Population in this research was companies listed on the Main Board Stock Index in Indonesian Stock Exchange for 2013-2017. The sample is 189 observation and it was taken by using purposive sampling technique. Data analysis technique used in this research is path analysis and Sobel test. This research founded that free cash flow has a positive significant effect on firm value and dividend payout, free cash flow has a negative effect on investment opportunity set, dividend payout has a positive significant effect on firm value, and investment opportunity set has a positive significant effect on firm value. Furthermore, dividend payout act as a mediator on the effect of free cash flow on firm value, but investment opportunity unable to mediate the effect of free cash flow on firm value.
Validation of an Independent Web-Based Tool for Measuring Visual Acuity and Refractive Error (the Manifest versus Online Refractive Evaluation Trial): Prospective Open-Label Noninferiority Clinical Trial. (Preprint)
Authors: Wisse Robert P L , Muijzer Marc B , Cassano Francesco , Godefrooij Daniel A , Prevoo Yves F D M , Soeters Nienke
Published: June 2019

BACKGROUND

Digital tools provide a unique opportunity to increase access to eye care. We developed a Web-based test that measures visual acuity and both spherical and cylindrical refractive errors. This test is Conformité Européenne marked and available on the Easee website. The purpose of this study was to compare the efficacy of this Web-based tool with traditional subjective manifest refraction in a prospective open-label noninferiority clinical trial.

OBJECTIVE

The aim of this study was to evaluate the outcome of a Web-based refraction compared with a manifest refraction (golden standard).

METHODS

Healthy volunteers from 18 to 40 years of age, with a refraction error between –6 and +4 diopter (D), were eligible. Each participant performed the Web-based test, and the reference test was performed by an optometrist. An absolute difference in refractive error of <0.5 D was considered noninferior. Reliability was assessed by using an intraclass correlation coefficient (ICC). Both uncorrected and corrected visual acuity were measured.

RESULTS

A total of 200 eyes in 100 healthy volunteers were examined. The Web-based assessment of refractive error had excellent correlation with the reference test (ICC=0.92) and was considered noninferior to the reference test. Uncorrected visual acuity was similar with the Web-based test and the reference test (P=.21). Visual acuity was significantly improved using the prescription obtained by using the Web-based tool (P<.01). The Web-based test provided the best results in participants with mild myopia (ie, <3 D), with a mean difference of 0.02 (SD 0.49) D (P=.48) and yielding a corrected visual acuity of >1.0 in 90% (n=77) of participants.

CONCLUSIONS

Our results indicate that Web-based eye testing is a valid and safe method for measuring visual acuity and refractive error in healthy eyes, particularly for mild myopia. This tool can be used for screening purposes, and it is an easily accessible alternative to the subjective manifest refraction test.

Digital cognitive behaviour therapy for insomnia (CBTi) for adolescents with mental health problems. Results from a feasibility open trial. (Preprint)
Authors: Cliffe Bethany , Croker Abigail , Denne Megan , Smith Jacqueline , Stallard Paul
Published: June 2019

BACKGROUND

Insomnia in adolescents is common, persistent, and associated with poor mental health including anxiety and depression. Insomnia in adolescents attending child mental health services is seldom directly treated and the effects of digital CBTi on the mental health of adolescents with significant mental health problems is unknown.

OBJECTIVE

This paper reports an open study assessing the feasibility of adding supported online CBT for insomnia to the usual care of young people aged 14-17 years attending specialist child and adolescent mental health services.

METHODS

Thirty-nine adolescents aged 14-17 attending specialist child and adolescent mental health services with insomnia were assessed and offered digital CBTi. The digital intervention was Sleepio, an evidence based, self-directed, fully automated CBTi that has proven effective in multiple randomized controlled trials with adults. Self-report assessments of sleep (Sleep Condition Indicator, Insomnia Severity Scale, online sleep diaries), anxiety (Revised Child Anxiety and Depression Scale) and depression (Mood and Feelings Questionnaire) were completed at baseline and post-intervention. Post-use interviews assessed satisfaction with digital CBTi.

RESULTS

Average baseline sleep efficiency was very poor (52.9%) with participants spending an average of 9.6 hrs in bed but only 5.1 hrs asleep. All scored <17 on the Sleep Condition Indicator with 36/39 (92.3%) scoring ≥15 on the Insomnia Severity Scale, suggesting clinical insomnia. 36 (92.3%) scored ≥ 27 on the Mood and Feelings Questionnaire for major depression and 20 (51.3%) had clinically elevated symptoms of anxiety. The majority (76%) were not having any treatment for their insomnia, with the remaining 24% receiving medication. Sleepio was acceptable with 77% (30/39) activating their account and 67% (21/30) completing the program. Statistically significant pre-post improvements were found in weekly diaries of sleep efficiency (p=.005) and sleep quality (p=.001) and on measures of sleep (SCI; p=.001: ISI; p=.001), low mood (MFQ; p=.024) and anxiety (RCADS; p=.015). Satisfaction was high; with 89% finding Sleepio helpful, 94% would recommend it to a friend with 39% expressing a definite preference for a digital intervention.

CONCLUSIONS

Our study has a number of methodological limitations, particularly the small sample size, absence of a comparison group and follow-up assessment. Nonetheless, our findings are encouraging and suggest that digital CBTi for young people with mental health problems might offer an acceptable and an effective way to improve both sleep and mental health.

Published: June 2019

Background and objectives

Whether combining changes in eGFR and urine albumin-to-creatinine ratio (UACR) is more strongly associated with outcomes compared with either change alone is unknown.

Design, setting, participants, & measurements

We analyzed 8766 patients with type 2 diabetes in the Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation Observational (ADVANCE-ON) study. Changes in eGFR and UACR (baseline to 2 years) were defined as ≥40% decrease, minor change, and ≥40% increase. The primary outcome was the composite of major macrovascular (nonfatal or fatal myocardial infarction, nonfatal or fatal stroke, or cardiovascular death), major kidney events (requirement for kidney replacement therapy or kidney death), and all-cause mortality.

Results

Over a median of 7.7 years of follow-up, 2191 primary outcomes were recorded. Strong linear associations between eGFR and UACR changes and subsequent risk of the outcome were observed. For eGFR, the hazard ratios were 1.58 (95% confidence interval [95% CI], 1.27 to 1.95) for a decrease ≥40% and 0.82 for an increase ≥40% (95% CI, 0.64 to 1.04) compared with minor change. For UACR, the hazard ratios were 0.96 (95% CI, 0.85 to 1.07) for a decrease ≥40% and 1.32 (95% CI, 1.19 to 1.46) for ≥40% increase compared with minor change. Compared with dual minor changes, both an eGFR decrease ≥40% and a UACR increase ≥40% had 2.31 (95% CI, 1.67 to 3.18) times the risk of the outcome, with evidence of interaction between the two markers.

Conclusions

Clinically meaningful decreases in eGFR and increases in UACR over 2 years, independently and in combination, were significantly associated with higher risk of major clinical outcomes.

The Hospitality Center is one of the business incubators managed by the Faculty of Tourism and Hospitality of the UNP. Currently, the Hospitality Center provides lodging services and will be equipped with other supporting facilities. Consumers who become the market share of this accommodation are University guests, trainees, students and employees, especially those in Padang State University. As one of the business incubators since UNP changed its status to a Public Service Agency, this unit is expected to be one of the pioneers of income generating which can contribute significantly to the income of the UNP. To increase Occupancy and maximize revenue and Hospitality Center, it is necessary to study the servicescape that is needed (Importance) by guests and how the performance (performance) of the servicescape itself has been provided by the manager. This study seeks to assess the level of importance and performance of each item from servicescapes consisting of ambient conditions, spatial layout and functionality, sign, symbol, and artifacts. The purpose of this study is; to determine the level of importance and performance of servicescapes, so that it can facilitate the assessment and help take action on servicescapes that have been analyzed and grouped into importance performance analysis, it can assess the condition of existing servicescapes and can make priority scales future improvements. The research method used in this study was descriptive method with a quantitative approach by distributing questionnaires to 80 guests who had or were staying at the Hospitality Center, Padang State University. The results of the research trials show that there were no declarations from the instruments prepared. The results of the study show that all the attributes of servicescapes belong to the B quadrant (Maintain Achievement), where the level of importance of servicescapes required by guests, has been met by the manager.

Authors: Silva Jean Pierre Pierote
Published: June 2019

Esse artigo tem como objetivo pensar as relações entre o patrimônio cultural edificado e os modos de habitar a cidade. Parte-se de uma perspectiva pós-colonial e toma-se como base a experiência de pesquisa de campo etnográfica realizada durante uma residência artística na cidade de Rio de Contas (BA) em 2013. As questões em torno da relação entre as políticas de patrimônio cultural, a perspectiva pós-colonial e o uso metodológico de práticas artísticas na pesquisa etnográfica são as balizas que direcionam este trabalho. Elas permitiram pensar o patrimônio cultural também como uma plataforma discursiva onde os moradores das cidades patrimonializadas se apropriam material e simbolicamente dessas edificações, compondo outros usos e sentidos para o patrimônio no presente.
Discursos Y Prácticas Despatologizantes, Aportes desde la Narrativa: La Fábrica de la Locura
Authors: Pérez Gastón
Published: June 2019

El presente artículo desarrolla una sistematización y análisis sobre una intervención desarrollada en mi actividad profesional como trabajador social en un Centro de Recuperación estatal. Surge de las tensiones en el abordaje con una persona con diagnóstico de demencia y la inquietud por generar narrativas que posibiliten prácticas y discursos despatologizantes.El marco teórico consta de cuatro ejes, donde destacan: discursos/prácticas en claves de poder-saber, la herencia positivista y su reproducción acrítica; la categoría de enfermedad mental como construcción teórica; los aportes del análisis institucional; y la denuncia de lo natural desde la semiología.La metodología consiste en el enfoque biográfico-narrativo, entendiendo la identidad narrativa como permanente (re)significación en relación con los espacios transitados, generando la apertura a nuevos discursos y universos de sentido, a nuevas realidades.La reflexión se centra en la necesidad de generar discursos/prácticas por fuera de las hegemónicas biologicistas, conscientes de las lógicas de poder que las atraviesan, construyendo lugares más empáticos con el sufrimiento humano. AbstractThis article develops a systematization and analysis of an intervention made in my professional activity as a social worker in a state Recovery Center. It comes from the tensions in the approach of a person diagnosed with dementia and the need to create narratives that enable de-pathologizing practices and discourses.The theoretical framework consists of four main ideas, including: discourses/practices in the form of power-knowledge, the positivist heritage and its uncritical reproduction; the category of mental illness as a theoretical construction; the contributions of institutional analysis; and the criticism of what is natural from semiotics.The methodology consists of a biographical-narrative approach, understanding the narrative identity as a constant (re)signification in relation to the inhabited spaces, welcoming new discourses and universes of meaning, new realities.The reflection is focused on the need to create discourses/practices outside the hegemonic biologistic ones, being aware of the logics of power that go through them, building places which are more empathetic with human suffering.

Published: June 2019

We analyze a first order in time Fourier pseudospectral scheme for Swift-Hohenberg equation. One major challenge for the higher order diffusion non-linear systems is how to ensure the unconditional energy stability and we propose an efficient scheme for the equation based on the convex splitting of the energy. The?oretically, the energy stability of the scheme is proved. Moreover, following the derived aliasing error estimate, the convergence analysis in the discrete l2-norm for the proposed scheme is given.
Performatividad de género en el teatro para niños. Estrategias para el análisis de obras infantiles
Authors: Casella Germán
Published: June 2019

Este artículo tiene como objetivo delinear estrategias para el análisis de micropoéticas escénicas destinadas a las infancias desde las categorías de género y sexo. Para hacerlo, se desarrollarán los postulados de Judith Butler (2016, 2002) acerca de la performatividad del género como un acto estilizado y reiterado, constitutivo de las categorías generizadas. Serán contrapuestos con la comprensión del teatro para niños como un acontecimiento formativo de identidades. Se destacará su producción a partir de relaciones contingentes entre productores y espectadores que son, por tanto, asimétricas. Finalmente, a modo de ejemplo, se aplicarán las estrategias al caso La bella durmiente contada por una abuela, de Lorena Velazquez y Juan Carlos Fiasconaro.
O PAPEL DA POLÍTICA NACIONAL DOS RESÍDUOS SÓLIDOS NA LOGÍSTICA REVERSA EM EMPRESAS FARMACÊUTICAS
Authors: Luna Roger Augusto , Viana Fernando Luiz Emerenciano
Published: June 2019

A grande utilização de produtos fármacos em diversos segmentos da saúde vem se tornando um possível problema ambiental, uma vez que o descarte incorreto, feito pela população, dos resíduos no meio ambiente por falta de legislação especifica de retorno destes resíduos, ainda é uma realidade nacional. Esta lacuna proporcionada pela falta de legislação reflete diretamente nos processos de logística reversa da indústria farmacêutica. A criação da Política Nacional dos Resíduos Sólidos (PNRS), lei federal 12.305 de 2010, busca exatamente suprir esta necessidade e propor ações de responsabilidade compartilhada em todos os elos da cadeia de suprimento. Esta pesquisa tem o objetivo de analisar o processo de logística reversa utilizado pela indústria farmacêutica no Brasil à luz da Política Nacional de Resíduos Sólidos (PNRS), constituindo um estudo qualitativo, que envolveu a realização de entrevistas com gestores de empresas fabricantes de medicamentos, representante de classe, redes de farmácias e o órgão regulador do setor. Como resultados, pode-se observar uma extensa cadeia de suprimento, a qual é responsável pela distribuição dos medicamentos, porém, não ativa no processo reverso, com isto, identificou-se apenas um fluxo reverso para os medicamentos vencidos nas farmácias, não se preocupando com o último elo de consumo. Foram identificados como principais direcionadores da logística reversa na indústria farmacêutica os aspectos mercadológicos, operacionais, legais e custo. Por fim, observou-se que a cadeia de suprimento da indústria farmacêutica, desde o fabricante até as redes de farmácias, ainda não está preparada para atender as demandas da PNRS, embora exista uma articulação em curso visando ao atendimento dessas demandas.

Solar panel is gaining popularity as one of the source of alternative energy especially in tropical country. Solar panel users need to know how much energy is produced and what components it takes before starting to make a solar panel system. A comparison between ideal energy and actual energy will help to evaluate the performance of solar panel to show how much energy it will produce under a real condition. In this research, a 20 WP solar panel was used and the data collection was performed from 9 May 2018–9 July 2018 in Bekasi City. Collected data are voltage and current produced by the solar panel every ten minutes for ten hours continuous measurements. The solar panel performance was analysed by comparing maximum power, average power, and energy production per week. From the data measurements and analysis, it is found that the total energy produced is 3797 Wh, the average energy produced in one day is 61.24 Wh, and the average peak hour is 11.20 a.m.

Authors: Sobolewski Peter , Murthy N. Sanjeeva , Kohn Joachim , El Fray Miroslawa
Published: June 2019

Proteins adsorbed onto biomaterial surfaces facilitate cell-material interactions, including adhesion and migration. Of particular importance are provisional matrix components, fibrinogen (Fg) and fibronectin (Fn), which play an important role in the wound healing process. Here, to assess the potential of a series of elastomeric poly(butylene succinate) copolymers for soft tissue engineering and regenerative medicine applications, we examined the adsorption of Fg and Fn. We prepared spin-coated thin films of poly(butylene succinate) homopolymer and a series of elastomeric poly(butylene succinate) copolymers with butylene succinate (PBS, hard segment) to succinate-dimer linoleic diol units (DLS, soft segments) weight ratios of 70:30, 60:40, and 50:50. X-ray diffraction was used to assess crystallinity, while the obtained thin films were characterized using quartz crystal microbalance with dissipation monitoring (QCM-D) and atomic force microscopy (AFM). Protein adsorption was assessed using QCM-D, followed by data analysis using viscoelastic modeling. On all three copolymers, we observed robust adsorption of both key provisional matrix proteins. Importantly, for both proteins, viscoelastic modeling determined that the adlayers were 30–40 nm thick and had low shear modulus values (<25 kPa), thus indicating soft orientations (end-on for Fg) or conformations (open for Fn) of the hydrated proteins. Overall, our results are very encouraging, as they predict excellent cell adhesion and migration, key features enabling tissue integration of potential PBS-DLS scaffolds.

A New Four-Parameter Cubic Equation of State for Predicting Fluid Phase Behavior
Authors: he zhiren
Published: June 2019

A new four-parameter cubic equation of state (EoS) is generated by incorporating the critical compressibility factor (Zc) apart from the critical pressure (Pc) and temperature (Tc). One free parameter in the denominator of the attractive term and two parameters in the alpha function are adjusted using the experimental data of saturated liquid density, vapor pressure, and isobaric liquid heat capacity of 48 components including hydrocarbons and non-hydrocarbons. Applying this equation of state, saturated liquid density, saturated vapor density, and vapor pressure of pure components are accurately reproduced compared with experimental values. Furthermore, the predicted properties including derivatives of alpha function, such as enthalpy of vaporization, entropy of vaporization and isobaric heat capacity of liquid, also have decent accuracy. The global average absolute relative deviation (AAD) of saturated liquid density, saturated vapor density, saturated vapor pressure, enthalpy of vaporization, entropy of vaporization, and isobaric heat capacity of liquid in a wide reduced temperature (Tr) range of subcritical region reproduced by this work are 4.33%, 4.18%, 3.19%, 2.26%, 2.27%, and 5.82%, respectively. Substantial improvement has been achieved for the isobaric liquid heat capacity calculation.
Car-Parrinello Monitor for More Robust Born-Oppenheimer Molecular Dynamics
Authors: Wang Lee-Ping , Song Chenchen
Published: June 2019

Born-Oppenheimer molecular dynamics (BOMD) is a promising simulation method for exploring the possible reaction pathways of a chemical system, but one significant challenge is the increased difficulty of converging the self-consistent field (SCF) calculation that often accompanies the breaking and forming of chemical bonds.To address this challenge, we developed an enhancement to the BOMD simulation method called the Car-Parrinello monitor (CPMonitor) that uses Car-Parrinello molecular dynamics (CPMD) to recover from SCF convergence failures.CPMonitor works by detecting SCF convergence failures in BOMD and switching to a CPMD Hamiltonian to propagate through the region of configuration space where the SCF calculation is unable to converge, then switching back to BOMD when good convergence behavior is re-established.We present a series of simulation studies that use CPMonitor, including detailed studies of the thermodynamic and dynamical properties of simple systems, as well as ab initio nanoreactor simulations containing transition metal atoms that were previously not possible to simulate using standard BOMD methods.Our studies show that CPMonitor can make BOMD simulations robust to SCF convergence difficulties and improve simulation performance and stability in reaction discovery applications.
Cultura Política e Assistência Social:
Authors: Oliveira Heloísa Maria José de
Published: June 2019

O presente artigo discute a Política de Assistência Social no contexto dos sistemas de proteção social, sob a ótica da Cultura Política. Estudos nesse campo têm revelado sua pertinência no sentido de apontar alguns dos limites que se impõem à consolidação da Assistência Social em uma perspectiva democrática e cidadã. Diferentes atitudes e orientações, marcadas pela lógica do clientelismo e do favor e estimuladoras do atendimento residual e focalista às demandas sociais, minam o reconhecimento dessa política como pública, inviabilizando suas prerrogativas legais inscritas na Constituição e na Lei Orgânica da Assistência Social. O objetivo deste ensaio, portanto, é indicar algumas tendências presentes na Cultura Política da Assistência Social, de modo a contribuir para o desvelamento de seus dilemas e perspectivas no âmbito da proteção social.

ISSUES OF EFFICIENCY FOR PUBLIC-PRIVATE PARTNERSHIPS IN THE WATER SECTOR
Authors: Frone Simona , Frone Dumitru Florin
Published: June 2019

The water resources are critical for the economic development in a country or region, since the pollution and depletion of the waters are raising concerns for the environmental and economic efficiency of their management. This outlook calls for analysis on economic and financial issues and risks associated with specific investment projects in water supply and sanitation infrastructure WSS. In previous research outcomes we have shown successful models of Public-Private Partnerships (PPP) used to manage and mitigate the risks and improve performance in providing the public services of Water Supply and Sanitation (WSS). The main objective of this paper is to reiterate the PPP as an efficient business model for the water sector, by employing several methodologies: literature review, case studies, performance indicators, analysis and synthesis. Some features and experiences of PPP in the water sector are resumed and analysed, considering recent developments and leading to conclusions and recommendations on their opportunity and efficiency in Romania.

Amid the Changing Landscape of City, Class and Imperial Russian Policy: The Habitus of the Kaunas Urban Elite and Their Symbolic Representation in the Early 19th Century
Authors: Civinskas Remigijus
Published: June 2019

Changing 19th-century socio-economic identities have been a major topic of debate among European historians. Obviously, there are disagreements over the scientific analysis and objectivity of identities research in Lithuanian and Western historical narratives. This is especially relevant when discussing the specific characteristics of urban society. In this article, the author analyses the social identities of the Kaunas burgher elite, and the factors which affected the group in the late 18th and early 19th centuries. The theoretical approach of the sociologist Pierre Bourdieu is used to describe the phenomenon. The habitus concept is used to analyse the facts, as it helps to reveal representations of the identification of elites with the city and estate structures (the early Kaunas urban tradition and the new Imperial Russian classes).

Pelayanan antenatal care memainkan peranan yang penting dalam mencegah dan mendeteksi komplikasi obstetrik sedini yang mungkin serta ditangani pada tahapan awal untuk mendapatkan ibu dan bayi yang sehat. Tujuan penelitian ini untuk Mengetahui hubungan antara tingkat pendidikan ibu dengan pemeriksaan awal kehamilan (K1) di Puskesmas Krebet Pilangkenceng Madiun.

Jenis penelitian analitik korelasional menggunakan pendekatan cross sectional. Variabel penelitian tingkat pendidikan ibu sebagai variabel independent dan pemeriksaan awal kehamilan (K1) sebagai variabel dependent. Populasi penelitian seluruh ibu hamil di Puskesmas Krebet Pilangkenceng Madiun pada Bulan Januari - Agustus 2016 sebanyak 49. Sampel diambil dengan teknik simple random sampling sebanyak 43 responden pada tanggal 3 Oktober – 30 Desember 2016. Data dikumpulkan dalam bentuk data sekunder kemudian hasil pengumpulan data diuji dengan uji wilcoxon.

Hasil penelitian menunjukkan bahwa sebagian besar responden paling banyak pendidikan responden adalah menengah (SLTA) sebanyak 29 responden (67,4%) dan kunjungan K1 Akses sebanyak 35 responden (81,4%) dan kunjungan K1 murni sebanyak 8 responden (18,6%).

Hasil statistic Wilcoxon Signed Rank pada program SPSS diperoleh hasil ρ = 0,042. Jika α = 0,05 maka dapat disimpulkan ρ < α artinya H ditolak berarti ada hubungan antar tingkat pendidikan dengan pemeriksaan awal keha- 0 milan (K1).

Pada umumnya semakin tinggi pendidikan seseorang akan mempengaruhi kunjungan kehamilan yaitu responden yang berpendidikan tinggi cenderung melakukan kunjungan ANC K1 murni, sedangkan responden yang berpendidikan rendah cenderung memilih kunjungan ANC K1 akses. diharapkan ibu juga dapat meningkatkan informasi yang diperoleh tentang kunjungan ANC sehingga dapat melakukan kunjungan dengan lebih aktif dan dapat mendeteksi kelainan pada kehamilan secara dini.
Principals’ Perceptions of Teacher Evaluation Reform from Structural and Human Resource Perspectives
Authors: Campbell John Wilson , Derrington Mary Lynne
Published: June 2019

Driven by Race to the Top funding and quickly designed and deployed in 2010-2011, a new teacher evaluation policy in Tennessee altered principals’ supervisory practices regarding their use of time for observation and reporting, their interaction with teachers, and the methods for giving teachers performance ratings. In addition, student test score data were integrated into final ratings, and professional consequences were linked with those ratings. Researchers in this study followed fourteen school principals over a five-year period to understand how their perceptions of new evaluation policy components affected their implementation. Data were analyzed using the structural and human resource frames of Bolman and Deal (2017) to interpret policy demands, principals’ perceptions, and variations in implementation. Findings indicate that principals appeared to reject strict application of the policy’s structurally focused components and procedures, while supporting collaborative, human resource-oriented approaches for promoting teacher growth and professional development.
Unsteady hydromagnetic flow of Oldroyd-B fluid over an oscillatory stretching surface: a mathematical model
Authors: Khan Sami Ullah , Ali Nasir
Published: June 2019

In the present work, we have studied an unsteady, two-dimensional boundary layer flow of a magnetohydrodynamics (MHD) Oldroyd-B fluid over an oscillatory stretching surface. The problem is modeled by using constitutive equations. The number of independent variables in the governing equations are reduced by using appropriate dimensionless variables. The analytical solution is computed by using homotopy analysis method. The influences of various physical parameters such as Deborah numbers, ratio of angular frequency to stretching rate parameter and Hartmann number on time-series of velocity and transverse velocity profiles at different time instants are investigated and discussed quantitatively with the help of various graphs. It is observed that amplitude of velocity increases by increasing ratio of oscillating frequency to stretching rate parameter while decreases by increasing Hartmann number. It is further observed that the magnitude of velocity decreases by increasing Hartmann number and Deborah numbers in the terms of relaxation time parameter.
REMOCIÓN DE UN INSTRUMENTO FRACTURADO DURANTE LA TERAPIA ENDODÓNTICA: REPORTE DE UN CASO
Authors: Vélez Astudillo Rómulo Andres
Published: June 2019

Durante los procedimientos de preparación del conducto radicular, el potencial de fractura de instrumentos está siempre presente. Cuando un instrumento se fractura, produce ansiedad al tratante, así como, una obstrucción metálica del conducto lo que dificulta aún más la limpieza y conformación. Se debe intentar siempre remover el instrumento fracturado, y si la recuperación no es posible; se debe evaluar la posibilidad de sobrepasarlo. El propósito de este artículo es reportar un caso clínico de remoción de un instrumento endodóntico fracturado en el interior del conducto radicular, mediante la creación de un espacio alrededor del instrumento y con la ayuda de dos limas Hedström que traccionan de él, removiéndolo por completo.
