On the mixed convective carbon nanotube flow over a convectively heated curved surface

In this article, mixed convective boundary layer stream of nanofluid flow with carbon nanotube as nanoparticles and transmission of heat over a coiled stretched surface are studied. The influence of magnetic orientation and velocity slip is also encountered in this problem. Two classes of carbon nanotubes, SWCNT and MWCNT, are considered as nanoparticles and water as a pure liquid. The foremost leading partial differential equations (PDEs) are formulated through curvilinear coordinate system subjected to proper boundary conditions. To simplify this nonlinear PDE‐associated model, we have employed a compatible similarity conversion and acquired the nonlinear dimensionless ordinary differential equations (ODEs). To determine the requisite numerical solution of the transformed problem, a shooting procedure embedded with RK‐4 technique has been applied. Various pictorial attempts have been initiated against different parametric inputs to reveal the hydrothermal scenario. Some physical quantities like skin friction and Nusselt numbers are calculated to investigate flow distribution inside the preferred system. A comparison with earlier research depicts parallel outcomes. Results assured that velocity is a cumulative function with positive increment of curvature parameter, but an opposite scenario is shown for temperature for both type of nanofluids. The amount of heat transition has been declined against the improvement of the magnetic parameter.
Understanding drivers and outcomes of lurking vs. posting engagement behaviours in social media-based brand communities

ABSTRACT Social media-based brand communities (SMBBC) are ideal tools to develop Consumer Engagement (CE). Yet, brands do not fully understand whether members are really loyally engaged with the brand and uncertainties remain regarding SMBBC return on investment. Therefore, our aim is to understand what drives CE within SMBBC, to relate it to different CE behaviours and to study its impact on brand loyalty. Data from 213 Facebook users was analysed using PLS-SEM. The study concludes that the drivers for passive/lurking and active/posting behaviours differ and vary according to brand type, with the former revealing a stronger positive association with brand loyalty than the latter. This study also provides valuable insights into CE literature and to brands holding SMBBC, helping them to successfully develop social media strategies.
Optimal Location and Size of Distributed Generators in an Electric Distribution System based on a Novel Metaheuristic Algorithm

This paper proposes a method for optimizing the location and size of Distributed Generators (DGs) based on the Coyote Algorithm (COA), in order to minimize the power loss in an Electric Distribution System (EDS). Compared to other algorithms, COA does not need control parameters during its execution. The effectiveness of COA was evaluated in an EDS with 33 nodes for two scenarios: the optimization of location and capacity of DGs in an initial radial configuration, and the best radial configuration for power loss reduction. Results were compared with other methods, showing that the proposed COA is a reliable tool for optimizing the location and size of DGs in an EDS.
Equilibrium Homophily in Networks

Abstract I look at the equilibrium effects of homophily in network formation games having positive externalities. I show that very weak preferences for network effects (such as a preference for being part of a clique) may result in very high levels of homophily at equilibrium. I present an empirical procedure that allows an evaluation of the role of network effects on the observed level of homophily in the data. I apply my method to the formation of friendship networks in the USA. I show that network effects are small and have a negligible contribution to the observed racial homophily in friendship networks.
The relationship between health literacy and indicators of decision making for colorectal cancer screening among African Americans

Title of dissertation: THE RELATIONSHIP BETWEEN HEALTH LITERACY AND INDICATORS OF DECISION MAKING FOR COLORECTAL CANCER SCREENING AMONG AFRICAN AMERICANS Erin Kelly Tagai, Doctor of Philosophy, 2016 Directed by: Professor Cheryl L. Holt Assistant Professor Mary A. Garza Department of Behavioral and Community Health African Americans are disproportionately affected by colorectal cancer (CRC) incidence and mortality. CRC early detection leads to better treatment outcomes and, depending on the screening test, can prevent the development of CRC. African Americans, however, are screened less often than Whites. Aspects of decision making (e.g., decisional conflict, decision self-efficacy) can impact decision making outcomes and may be influenced by social determinants of health, including health literacy. However the relationship between social determinants of health and indicators of decision making in this population is not fully understood. Additionally, individuals have a choice between different CRC screening tests and an individual’s desire to use a particular screening test may be associated with social determinants of health such as health literacy. This study aimed to examine the relationship between social determinants of health and indicators of decision making for CRC screening among African Americans. A total of 111 participants completed a baseline and 14-month follow-up survey assessing decisional conflict, decision self-efficacy, decisional preference (shared versus informed decision making), and CRC test preference. Health literacy was negatively associated with decisional conflict and positively associated with decision self-efficacy (ps < .05). Individuals who were unemployed or working part-time had significantly greater decisional conflict than individuals working full-time (ps < .05). Individuals with a first-degree family history of CRC had significantly lower decision self-efficacy than individuals without a family history (p < .05). Women were significantly more likely to prefer making a shared decision rather than an informed decision compared to men (p < .05). Lastly, previous CRC screening behavior was significantly associated with CRC test preference (e.g., individuals previously screened using colonoscopy were significantly more likely to prefer colonoscopy for their next screening test; ps < .05). These findings begin to identify social determinants of health (e.g., health literacy, employment) that are related to indicators of decision making for CRC among African Americans. Furthermore, these findings suggest further research is needed to better understand these relationships to help with the future development and improvement of interventions targeting decision making outcomes for CRC screening in this population.

Health, Wealth, and Informality over the Life Cycle

How do labor market and health outcomes interact over the life cycle in a country characterized by a large informal sector and strong inequalities? To quantify the effects of bad health on labor market trajectories, wealth, and consumption, we develop a life-cycle heterogeneous agents model with a formal and an informal sector. We estimate our model using data from the National Income Dynamics Study, the first nationally representative panel study in South Africa. We run counterfactual experiments and show that health shocks have an important impact on wealth and consumption. The channel through which these shocks propagate strongly depends on the job status of individuals at the time of the shock. For formal workers, bad health reduces labor efficiency, which translates into lower earnings. For informal workers and the non-employed, the shock lowers the job finding rate and increases job separation into non-employment, which results in a surge in non-employment spells. As bad health spells persist more for non-employed than for employed individuals, the interaction between labor market risks and health risks generates a vicious circle.
Neurobiological disease markers in drug naïve schizophrenia patients in Taiwan : a cross sectional study

____________________________________________________________________ A major factor driving research into the pathophysiology of schizophrenia has been responsiveness to antipsychotic (dopamine antagonist) medication. Despite this it remains unclear whether there is a detectable disorder of dopamine function in patients who develop schizophrenia and if so, how it relates to other physiological markers of the condition. One reason why research in this area is such a challenge is the confounding effects of antipsychotic treatment. I carried out a case control study on drug-naïve patients with schizophrenia who presented to the university hospital clinic in Tainan, Taiwan. I obtained a number of clinical and neurobiological measures, thought to be possible disease biomarkers. I assessed patients before they received treatment using the following methods: (I) single photon emission computed tomography (SPECT) [Tc] TRODAT-1 for dopamine transporter (DAT) availability; and (II) Electroencephalograms to test event-related potentials (ERPs). Such measures were also obtained on healthy controls and appropriate comparisons made. Clinical state was assessed using standard scales. (I): DAT availability through [Tc]-TRODAT-1 SPECT was compared between 47 drug naïve patients with recent onset schizophrenia and 112 healthy controls. I also conducted a random effects meta-analysis of the available literature synthesizing the results of six comparable published papers as well as my current data. The mean specific striatal binding ratio showed a trend for a reduction among the patients compared with controls (estimated difference = 0.071; 95% CI 20.01, 0.15; P =.08). There was an effect of sex, whereby females had a higher ratio of specific striatal binding than males. Age was negatively correlated with the ratio of specific striatal binding, both in patients and controls. The meta-analysis provided a pooled standardized effect size (Cohen’s d) of -0.07 (95% CI: -0.31, 0.18; p= 0.60) for the patient versus control comparison in

Mediation of transformation by the v-fos oncogene: regulation of the invasive phenotype by histone deacetylases

Transformation of fibroblasts with the v-fos oncogene produces a highly invasive phenotype. Accordingly, genes up- and down-regulated by v-Fos are of crucial importance in mediating a multigenic invasion programme. Differential expression studies revealed that components of histone deacetylase (HDAC) transcriptional co-repressor complexes are up-regulated in FBR-v-Fos-transformed (FBR) cells. Since HDACs facilitate gene silencing, we investigated the consequences of inhibiting their activity in terms of gene re-expression and phenotypic changes. We treated FBR cells with the HDAC inhibitors, trichostatin A (TSA) and valproic acid (VPA), at a range of sub-growth-inhibitory concentrations. At higher concentrations within this range, actin stress-fibres reform, transformed morphology reverts, cells are less motile and invasion is inhibited. Significantly, however, at lower concentrations within this range we inhibit invasion and actin stress-fibres reform but morphology, motility and chemotaxis are unaffected. This demonstrates the involvement of different groups of genes in different aspects of the transformed phenotype. In a limited study, we found several genes, down-regulated in FBR cells, which are then re-expressed as a consequence of HDAC inhibition. Ectopic re-expression (stable and transient) of three of these genes (RYBP, PCDHGC3 and STAT6) individually, in FBR cells, inhibits invasion without affecting morphology, motility or chemotaxis; nor do actin stress-fibres reform. These results demonstrate that the down-regulation of genes by Fos can be mediated by histone deacetylases and that many of these down-regulated genes, when normally expressed in fibroblasts, function to maintain the non-invasive state, in that their expression is incompatible with the invasive phenotype.
First total synthesis of 5(S)-hydroxyrecifeiolide

Abstract The first total synthesis of recently isolated 5(S)-hydroxyrecifeiolide has been described in ten straight forward linear steps with 14% of overall yield. The key reaction involves Jacobsen’s hydrolytic kinetic resolution, Copper catalysed Grignard reaction, Steglich esterification and ring closing metathesis reaction using Grubb's 2nd generation catalyst making the synthesis very elegant and simple. The stereogenic center at C5 was generated via Jacobsen's HKR which was confirmed by the Mandelate ester strategy as well as HPLC purity. Graphical Abstract
Inside the Black Box of Child Penalties

As developed countries have been unable to completely close the gender wage and participation gap, recent literature has revisited the old findings regarding the existence of child penalties in the labor market. Developing countries, however, present different challenges to the ability of women to work for pay. In this paper, we produce the first formal estimation of the child penalties in the Mexican labor market, and the second in a Latin American context. Using an event study approach and an instrumental variable strategy as a robustness check, we estimate the short run impact of children on labor force participation and wages, as well as their effect on transitions between the informal and formal sector. We find significant gaps between men and women in the short run impacts of children on both paid and unpaid work.
Knowledge, Barriers, and Motivation Related to Breast and Cervical Cancer Screening Among Women in Bojonegoro, East Java: A Qualitative Study

Background: Breast and cervical cancer remain a major cause of morbidity and mortality for wo­men in Indonesia. Although this cancer can be de­tected early, women are still less active in self-detecting breast and cervical cancer, so both cancers are found at an advanced stage. This study aimed to explore how women's knowledge, barriers, and motivations are related to early detection of breast and cervical cancer. Subjects and Method: This was a qualitative study, with focus group discussions (FGDs) and interviews with key informants. Discussions and in­terviews were conducted in the community within Ledok Kulon village, Bojonegoro Regency, East Java, Indonesia. Participants: FGD partici­pants involved 20 women, 10 women underwent FDG about cervical cancer and 10 other women conducted FGD about breast cancer. Three key informants interviewed with health worker and administrator that allow triangulation of res­pon­ses thereby increasing the validity of the findings. Participants were aged 20 to ≥60 years, with no history of symptoms or previous diagnosis of breast or cervical cancer. The women were inter­viewed in October-November 2019. The trans­cri­bed data were analyzed using content analysis. Results: Participants' knowledge about under­stan­ding, risk factors, signs and symptoms of breast and cervical cancer was still lacking. Par­ticipants attributed the cause of cervical cancer to the vaginal wound resulting in cervical cancer and signs of symptoms such as heartburn. Whe­reas for breast cancer participants were not know the signs and symptoms, they only said there was a lump in the breast. Barriers to screening were ashamed to be examined by health workers, afraid of testing procedures, feeling healthy and there were no signs of cancer. Screening motiva­tion were experiencing signs and symptoms of can­cer, family history of the disease and aware­ness of the disease/screening service. Conclusion: The study participants' knowledge of breast and cervical cancer was still lacking. To improve breast and cervical cancer screening, efforts must focus on reducing identified barriers and increasing motivation.

Prediction and Evaluation of Breast Myopathy

Broiler breast myopathies, including woody breast, white striping, and spaghetti breast, negatively impact the industry. Therefore, evaluation, prediction, and frequency of these muscle abnormalities on modern birds are important for decision making. Modern broilers are not highly active and often sit with the breast of the bird resting on the floor. Therefore, the first experiment was to promote bird movement and explore the impact on the breast myopathies. The movement was stimulated by human interaction (walking through pen) and higher light intensity so that birds walked around the pen more often throughout the day. The control group had normal low light intensity and minimal human interaction. However, the results were not different between the treatments on performance or breast myopathies. In other studies, broilers were palpated for woody breast (WB) and the breast region and/or fillets were measured for width, length, thickness, etc. in efforts to develop prediction of WB during growout and in the plant. Differences on the thickness and other part of the measurements on the fillets were found between WB categories (normal to severe) and it was determined that these features were good predictors for the differentiation on the severe WB and normal categories. Furthermore, palpation and measurements of the breast on the live bird throughout the growing period were also well correlated and some measurements were good predictors, like measurements on the cranial region of the breast with a cloth tape. There was observed that the different strains were different between each other as well the WB myopathy. Furthermore, the broiler breast myopathies demographic chapter to summarize all the data collected in 3 years with the most utilized strains in the market. Generally, myopathies increase as the birds get older and larger and they also increase AS breast yield increases to higher levels (breast yield > 30%). Additionally, males generally had greater WB than females and females had greater SM than males.
Analysis of differences in Banking Profitability Ratios before and after adoption of Internet Banking to bank listed on the Indonesian Stock Exchange (IDX)

The research aims to find out how the level of internet banking adoption and Return On Assets (ROA), Return On Equity (ROE), & BOPO on banks listed on the Indonesia Stock Exchange, as well as to analyze differences in Return On Assets (ROA), Return On Equity (ROE), & BOPO before and after implementing internet banking. The research method used in this study is included in quantitative research. The renewability in this study is that there is still no previous research that discusses the differences in banking performance before and after using e-banking in terms of ROA, ROE, & BOPO. Based on the analysis of the results of research and discussion presented earlier, it can be concluded that the provision of internet banking services have a significant influence on the financial performance of banks as measured by ROA, ROE, & BOPO listed in Indonesia Stock Exchange.
CASES OF STIGMATIZATION AND DISCRIMINATION AGAINST HIV AND HCV
PATIENTS BY MEDICAL PERSONNEL – COMPARATIVE SURVEYS

Introduction: Research results indicate that in Poland stigmatization and discrimination against HIV patients is occurring on the part of medical personnel. This phenomenon is characterized by a poorer treatment of patients due to infection, impediments to access to health services or refusing to provide medical care. the aim: The aim of the work was to analyze attitudes and the communication process between the patient and medical staff both before receiving health services as well as during the process of providing these services in order to investigate the causes and nature of the phenomenon of stigmatization and discrimination against patients with HIV and HCV by representatives of various medical professions. Material and methods: The study was conducted among patients with diagnosed HIV – the primary group and among patients with HCV – the control group. A total of 160 patients with HIV and HCV were investigated at the two outpatient clinics of the University Hospital in Krakow. The research used the author’s questionnaires of a comparative nature. results: Doctors, dentists, dental technicians, nurses and midwives are among the group of medical workers, who stigmatize and discriminate against patients diagnosed with HIV, which is manifested by the impediments or refusal to grant health services after the patient has provided information about the virus. The refusal to grant services to patients was often accompanied by the inducing guilt in patients due to having infection. Some patients withdrew themselves from health services despite the occurrence of medical need due to earlier ill-treatment by medical personnel. Patients, among the reasons for refusal, pointed to the personnel’s excuses for too long queues of patients, lack of appropriate qualifications or appropriate technical capabilities. Similar attitudes, though much less frequently and to a lesser extent, were noted in patients with HCV, constituting a control group in this study. This type of attitude, manifested by stigmatization and discrimination against patients, was not observed among paramedics, who are the group of medical professionals particularly often exposed to contact with potentially infectious material and therefore to an increased risk of infection. Conclusions: The cases of stigmatization and discrimination against patients with diagnosed HIV and HCV by medical personnel occur solely due to the patients’ infection with the virus. Cases of refusal are accompanied by anxiety and a sense of threat of infection, which may be related to the state of knowledge of the prevention of viral infections. Resignation of patients from medical care despite the need for health due to previous negative experiences in such situations, impediments in granting medical care or refusal to provide health services may have negative health consequences for these patients, and in the longer term, generate higher costs for the health care system due to the abandonment of earlier pro-health activities.
Controlled Evaluation in a Diesel Engine of the Biofuel Obtained with Ni/γ-Al2O3 Nanoparticles in the Hydrodeoxygenation of Oleic Acid

Abstract Renewable biodiesel with a high content of n-C17 alkanes was prepared through the catalytic hydrodeoxygenation of oleic acid under optimum conditions of temperature, reaction time and weight percentage of Ni deposited in γ-Al2O3. The hydrotreated vegetable oil (HVO) was blended with petrodiesel (20 % and 40 % of HVO) to evaluate its behaviour in a diesel engine. Comparative studies of power and emission of atmospheric pollutants such as NOx, CO, HC and smoke were evaluated under prepared blends and petrodiesel. The presence of HVO biodiesel at full load generated a slight decrease in power compared to petrodiesel; however, the decrease in emission of pollutants when using the blends containing HVO was significant. In the case of 40 % HVO were able to reduce more of 20 % of CO and HC emissions, and more than 40 % reduction in smoke when compared with petrodiesel. The NOx emissions of the blends with HVO had a significant slightly decrease. Further, the properties of Ni/γ-Al2O3 catalysts are justified by the results of EDS characterization, surface area (SBET), XRD, XPS, HR-TEM and it’s capacity to produce biodiesel.
