Derivation of a pH Dependent Solid-Liquid Interfacial Tension and Theoretical Interpretation of the Physicochemistry of Dewetting in the CO2-Brine-Silica System

The solid-liquid interfacial tension is a fundamental parameter in areas of wettability pertaining to adhesive bonds and petroleum engineering practice. In wettability issues related to surface functionalized polymeric materials design to achieve specific adhesive properties, the solid-liquid interfacial tension can be pH dependent due to amphoteric behavior. In this paper, we have used the theory of pH dependent surface charging and the 2-pk model as well as the site binding model of the electric double layer theory to derive a pH dependent solid-liquid interfacial tension equation. Following the fundamental relationship between solid-liquid interfacial tension and contact angle in light of Young’s equation, we have extended the theoretical basis of the derivation. Consequently, we have also derived a pH dependent cosine of the thermodynamic contact angle. Both equations give satisfactory explanations for observed experimental data available in the literature.
Liquid Crystal - Ferrofluid Dispersion

This research is aimed to determine the viscosity of liquid crystals by observing the motions of ferrofluid droplets in liquid crystal hosts under external magnetic fields. The ferrofluid droplets of size 20~30 I¼m were suspended in two plates covering the host liquid, and their motions under the magnetic field were observed with using a polarizing microscope. As the first step, three types of isotropic liquids, such as water, glycerin, and silicone oil, were employed as the host liquid. The speed of the moving droplet was much slower than the theoretical value calculated by the equilibrium between the magnetic force and the viscous force. This fact led us to one assumption, which the droplets involve the boundary layers under the magnetic field, and all results of isotropic liquids supported this fact. The main experiments of this research, using 4-cyano-4â€™-penthylbiphenyl (5CB), were conducted, and the result also supported the assumption above mentioned, which the new method to determine the 5CB viscosity was established. The experiments were conducted with several conditions, and unique anistropic properties of 5CB were observed with this new method. This research showed that that the new method enables us to observe anisotopic properties with the quantitate aspects.
Intrauterin fosterdød hos innvandrerkvinner og svenske kvinner – en svensk registerstudie

Background:Stillbirths or intrauterine fetal death have wide effects on families. This is about women’s and children’s health as well as equity in health for all. As Sweden becomes more multicultural, new challenges in equity on women’s and children’s health develope related to culture, communication, women –and family matters, lifestyle and medical issues.Aim: The aim of this study was to assess the occurence of stillbirths in immigrant women compared to Swedish women and investigate factors related to stillbirths.Method:Data from 904 646 newborns and their mothers during the period 1992-2001 was analysed using bivariat analyses. A literature study was undertaken with a systematic appraisal of relevant national and international research in the field.Results: The analyses showed that stillbirth was more common in non-European immigrant women. OR: 1,45 (95% CI 1,28-1,63). Non-European immigrant women in Sweden had higher odds of stillbirths compared to the background population.The litterature showed that non-European immigrant women have 2-3 times the risk of stillbirths, and the risk of stillbirths is also increased in women of lower socioeconomic status (SES). Other risk factors indicated to be important are age, consanguinity, smoking and the quality of perinatal care.Conclusions:Non-European immigrant women in Sweden have higher odds of stillbirths compared to the background population. These women also have an increased risk of low SES, which is itself a riskfactor of stillbirth. Appropriate knowledge of difference in health needs in different groups in the community is important for filling the health care needs and improving the medical treatments. Further research is needed from different sectors to assess the importance of lifestyle, language limitations and how these women are treated by the health care system.

Lichen Based Synthesis of Zinc Oxide Nanoparticles and Evaluation of its Neurotoxic Effects on Human Neuroblastoma Cells

Nanoparticles, smaller than 100 nm are synthesized by chemical and physical methods. Biological synthesis of nanoparticles is very popular in science recently. The aim of the study is green synthesis of zinc oxide nanoparticles (ZnO NPs) using the lichen extract (Ramalina fraxinea) and investigating the cytotoxic effects of ZnO NPs on human neuroblastoma cells (SHSY-5Y). Despite the widespread use of ZnO NPs, a limited number of studies have investigated the neurobiological effects of ZnO NP. Therefore, we tested the neurotoxic effect of green synthesized ZnO NPs administration and its neuroprotective effect against hydrogen peroxide-induced cell damage on SH-SY5Y human neuroblastoma cell line. The absorbance peak of the ZnO NPs was detected by UV–visible spectroscopy (UV-Vis) at 330 nm. The average diameter of ZnO NPs was measured as about 21 nm by Scanning Electron Microscope (SEM) and Field Emission Scanning Electron Microscope (FE-SEM) images. According to X-ray Diffraction (XRD) diagram, ZnO NPs were hexagonal in structure. The peaks observed in the Fourier Transform Infrared (FT-IR) test showed functional groups in the structure of the nanoparticles. According to our results, ZnO NPs may have beneficial effects at the low concentrations while neurotoxic effects at the higher doses in SH-SY5Y. In addition, we indicate that hydrogen peroxide-induced cell death could not reverse by ZnO NPs and its higher doses potentiated the neurodegenerative effect of hydrogen peroxide. In conclusion, here we report that ZnO NPs, widely used in various products, may have beneficial or harmful effects in a dose-dependent manner and play a role in neuropsychiatric disease, especially neurodegenerative diseases. This is the first study dealing with neurotoxicity on SHSY-5Y of Ramalina fraxinea extract based ZnO NPs.

The coach-parent-athlete triangle: an investigation in age group swimming

This thesis analyses the relationships that exist between the coach, the parent and the athlete within the context of age-group swimming. The interest in this area grew from the researcher's own experiences as a swimmer, a parent of swimmers and a swimming coach together with the underlying belief that the three members or what Byrne (1993) terms the 'sporting triangle' approach swimming experiences with different needs and wants. If other members of this sporting triangle fail to recognise or understand these needs then conflict may arise which could detract from the positive sporting experiences of the young swimmer. Because of the dearth of literature concerning relationships between all three members of this triad the literature review provides an overview of literature concerning the coach's, parent's and swimmers' roles and their relationships with one or more members of the sporting triangle. The importance of the context in which swimming takes place is also recognised and the age-group swimming structure within the United Kingdom is discussed. The research was carried out within two swimming clubs which were at participation level of competition. Within each club the field work involved observations followed by in-depth interviews with three swimmers and their parents together with the Chief Coach. The selection of the families was based around Hellstedt's (1987) model of the coach-parent-athlete triangle. Data were analysed using a grounded theory approach and Goffman's (1984) dramaturgical approach, alongside role theory and the notion of 'positioning' (Giddens, 1984; David and Harre, 1990) provided the basis for the reflexive pluralist methodology employed. The findings confirmed the complexity of the relationships within the triad together with the importance of the context in which social interaction takes place. The continual tension that exists between structure and agency was highlighted and seen as something that must be both understood (theoretically) and addressed (empirically) in any attempt to understand social interaction. The resulting data also confirmed that members of the 'sporting triangle' do not come to a swimming situation value free but bring with them a variety of expectations, needs and wants. As a result the need for strong lines of communication between all three members of the triad is recognised. Finally recommendations are made for policy and practice which it is hoped will ensure that young athletes' sporting experiences are positive.
Just what is the significance of communication in emergency management? An attempt to find empirical evidence by content analysis of reviews and debriefs of Australian emergency incidents and exercises

[Introduction]: Operational success in responding to an emergency might easily be measured in terms the number of lives and properties saved. Media images of fire fighters or State Emergency Services rescue boats in action during flood are evidence to the community, emergency managers and politicians that emergency agency resources are hard at work. Unfortunately, the effect of communication around the same emergency is hard to measure and such measurement not resourced. This may result in communication teams being starved of resources that can not easily be justified by emergency managers in terms of outcomes. Despite this, debriefing sessions often seem to be dominated by issues surrounding communication with the media and community. This study was commissioned by the Emergency Media and Public Affairs Research and Development committee and investigates suspicions of practitioners that, while communication teams are small, communication is a large component of emergency management that can easily turn into an issue (Rekers, Delaney & Wilson 2008). It attempts to quantify the significance of communication to emergency management. It will undertake a content analysis of a sample of documents that have been produced in Australia as a result of emergency incident and emergency exercise debriefing sessions and reviews from 2003 to 2008 and will measure the number of recommendations specific to or relating to communications against the total number of recommendations. The term ‘communications’ in this paper includes agency-community communication, community-agency communication, intra- and inter-agency communication and deals with messaging, channels and technology.
DSTATCOM-Fuel Cell System on Radial Low-voltage Distribution Network for Mitigating Voltage Rise Caused by High Penetration of Photovoltaic Systems

Article history: Received: 31 May, 2019 Accepted: 27 July, 2019 Online: 07 August, 2019 The Malaysian government has recently announced to increase the share of renewable energy generation from 2% to 20% of the total electricity consumption by year 2030. However, integrating a significant level of renewable energy sources on the distribution network without proper coordination will cause adverse effects that leads to unnecessary operation costs to the stakeholders. Various solutions including energy storage system are proven to be an effective way to overcome the issues caused by the integration of renewable energy sources. However, energy storage system using batteries have limitations such as limited life cycle and environmental hazards. As such, alternative source such as fuel cell which is well known for its zero pollutant can be considered. In this paper, a distributed static synchronous compensator integrated with a hydrogen system (DSTATCOM-Fuel cell) is proposed. The hydrogen system consists of fuel cell and electrolyzer to perform power exchange within the grid for regulating the voltage magnitude at 1 p.u. Various case studies have been conducted to validate the efficacy of this proposed combination and the results have shown that the DSTATCOM-Fuel cell can effectively mitigates the voltage rise up to 12.3% while maintaining high penetration of the photovoltaic systems.
Dual branches network for image superâ•’resolution

Recent studies have shown that deep convolutional neural networks (CNNs) signi ﬁ cantly boosted the performance of single-image super-resolution (SISR). In this Letter, the authors present a novel dual branches network (DBN) for SISR. Different from traditional CNN, the authors ’ DBN utilises the bene ﬁ ts of the residual structure and the densely connected structure together. Their key strategy is to divide the input path of the network into dual branches: a residual branch and a dense branch. This dual branches structure reuses valuable features and explores new features effectively. Experimental comparisons demonstrated the high ability of their DBN over the state-of-the-art framework for SISR with alleviating blurs of output images.

Physical modeling of the spreading of epigenetic modifications through transient DNA looping

We utilize theoretical modeling to explore the physical mechanisms that govern the spreading of epigenetic modifications along chromosomal DNA. We focus on a particular modification, methylation of lysine 9 of histone H3 (H3K9), which is a representative and critical epigenetic mark that affects chromatin structure and gene expression. Our model captures transient loop formation in chromosomal DNA that enables distal segments to be in close spatial proximity and permits methyltransferase to confer methyl marks over a broad range of genomic distances. Using our exact results for the statistical behavior of a semiflexible polymer, we find the looping rate for a chromosomal segment based on a mean first-passage time process on a free-energy landscape. From this treatment, looping kinetics are predicted to be the rate-limiting process for methyl spreading at large genomic distances, which explains the considerable variability in the methyl profile at such scales. We then develop a ‘phase diagram’ for methylation spreading versus the methylation rate and the concentration of HP1, which we identify as a global regulator of the state of the chromosomal DNA.
OUTLIER DETECTION IN THE ANALYSIS OF NESTED GAGE R&R, RANDOM EFFECT MODEL

Abstract Measurement system analysis is a comprehensive valuation of a measurement process and characteristically includes a specially designed experiment that strives to isolate the components of variation in that measurement process. Gage repeatability and reproducibility is the adequate technique to evaluate variations within the measurement system. Repeatability refers to the measurement variation obtained when one person repeatedly measures the same item with the same Gage, while reproducibility refers to the variation due to different operators using the same Gage. The two factors factorial design, either crossed or nested factor, is usually used for a Gage R&R study. In this study, the focus is only on the nested factor, random effect model. Presently, the classical method (the method of analysing data without taking into consideration the existence of outliers) is used to analyse the nested Gage R&R data. However, this method is easily affected by outliers and, consequently, the measurement system’s capability is also affected. Therefore, the aims of this study are to develop an identification method to detect outliers and to formulate a robust method of measurement analysis of nested Gage R&R, random effect model. The proposed methods of outlier detection are based on a robust mm location and scale estimators of the residuals. The results of the simulation study and real numerical example show that the proposed outlier identification method and the robust estimation method are the most successful methods for the detection of outliers.
Evaluation of the Efficacy of Meta-Analytic Structural Equation Modeling with Missing Correlations

Researchers often face problems with missing correlations when applying meta-analytic structural equation modeling (MASEM). However, methodological investigation regarding the performance of MASEM paired with a large proportion of missingness is limited. This study investigated the impacts of missing conditions on the performance of correlation-based MASEM, utilizing weighted-covariance generalized least squares (W-COV GLS) with pairwise deletion (PD) and/or multiple imputation (MI), and two-stage structural equation modeling (TSSEM), with two factorial models. The results show the superiority of W-COV GLS with MI and the necessity of including studies with complete correlation matrices for TSSEM and W-COV GLS with PD. We identified the boundary conditions in which each approach performs satisfactorily and illustrated how the variation of factor loadings impacts the performance of correlation-based MASEM.
Treatment of vitamin D deficiency in Dutch nursing home residents

Vitamin D supplementation in the elderly: guidelines and practice objective: In 2008, the Health Council of the Netherlands published an advice on vitamin D supplementation for the elderly. Nevertheless, suspicion arose at the Ministry of Health, Welfare and Sport and the Netherlands Nutrition Centre that vitamin D supplementation in the elderly is still insufficient. We aimed to determine the extent to which elderly care physicians actually followed the advice of the Health Council. design: questionnaire study. method: Brief questionnaires were sent to all elderly care physicians in the Netherlands. For comparison some questions were also posed to general practitioners at a network meeting of the Academic Network of GP Practices of the VU University Medical Center in Amsterdam. results: More than two-thirds of the respondents, both elderly care physicians and general practitioners, are familiar with the guidelines of the Health Council of the Netherlands on vitamin D supplementation in the elderly, but about half do not prescribe vitamin D when the guideline advises to do so. When supplementation is prescribed, about half of the elderly care physicians and a fifth of the general practitioners uses an insufficient dose. conclusion: The guidelines of the Health Council of the Netherlands on vitamin D supplementation in the elderly are not sufficiently followed by elderly care physicians and probably also not by general practitioners. Awareness of and support for the vitamin D supplementation guidelines among health care providers is still limited.
