Innovatively Arranged Curved-Ribbed Solar-Assisted Air Heater: Performance and Correlation Development for Heat and Flow Characteristics

Solar radiation is a rich and clean source of energy. It can be collected and converted to thermal energy with the help of flat plate collectors called the solar-assisted air heater. Because of the low coefficient of heat transfer of air, the solar-assisted air heater has low thermal performance which can be improved by creating local turbulence using surface roughness on the heat transferring plate. The present investigation has been conducted to perceive the influence of the curved-ribbed element with gap on flow and heat transfer. The roughness element is defined by using five non-dimensionlized parameters, i.e., relative roughness width (W/w), relative roughness pitch (P/e), relative gap width (g/e), relative roughness height (e/D), and relative gap distance (d/x). The radius of the curvature of the curved rib-element is kept constant and the experimental measurements were done under quasi-steady state. The thermohydraulic performance parameter improved by 3.61 times the smooth flat plate solar air heater (SAH), in curved-ribbed SAH for W/w = 3, P/e = 8, g/e = 1, e/D = 0.045, and d/x = 0.65 at Reynolds number of 23,000. The generalized relation for heat transfer and flow characteristics is also being developed and the predicted Nusselt number and friction factor with the accuracy of ± 7.5% and ± 6.7%, respectively.
Intravenous Immunoglobulin Therapy in Systemic Lupus Erythematosus

This review covers the major advances in the therapeutic potential of intravenous immunoglobulin (IVIG) in systemic lupus erythematosus (SLE) published in Medline during the last years. IVIG is a potent biological drug, utilised in neuroimmunologic, infectious, dermatologic, haematologic, autoimmune, inflammatory and idiopathic disorders. Over the past tw o decades, IVIG has been utilised as adjunct therapy for various manifestations of SLE. IVIG may be particularly attractive for neurological involvement. Compared to immunosuppressive agents, IVIG may be advantageous due to its few and transient minor adverse effects.
Studies on proliferative kidney disease using monoclonal antibody probes.

Studies on PKD using Monoclonal Antibody Probes Four monoclonal antibody (MAb) probes were produced which reacted against PK’X’ the causative agent of proliferative kidney disease in salmonids. Three of the MAbs appeared to be specific for carbohydrate epitopes whilst the fourth appeared to recognise a protein epitope. These probes were utilised to investigate the progression of the disease in rainbow trout, examine possible alternative hosts/ infective agents for the disease and to explore a novel method of purification for the PK’X’ cell. Purification of PK’X’ from kidney homogenates was investigated using immunomagnetism. The success of this was hampered by lymphocytes and macrophages adhering to the parasites’ surface. Incubations using detergents, trypsin, sonication and osmotic shock were employed to remove these cells with varying degrees of success. The course of the infection in rainbow trout was studied using immunohistochemistry on tissues sampled throughout the summer. This revealed that the antigenic characteristics of PK’X’ changed, with an intensification of staining of the carbohydrate binding MAbs on extrasporogonic stages and the protein binding MAb recognising secondary cells and sporogonic stages. Immunogold electron microscopy revealed that the carbohydrate binding MAbs were specific for the lysosomal membranes in the primary cell of the parasite whilst the protein binding MAb reacted to the surface of the secondary cell, vacuoles contained within it and this cell’s immediate surroundings. It was speculated that the extrasporogonic parasite undergoes autophagy with the development and release of the sporogonic stage. Aquatic oligochaetes from PKD enzootic rivers infected with Actinosporean species were studied using immunohistochemistry, electron microscopy and transmission experiments performed. However, the alternative host for the disease was not determined. Wild fish kidneys from PKD enzootic waters were tested with immunohistochemistry to determine the possible definitive host of PK’X’. An unidentified Sphaerospora sp. infecting Atlantic salmon reacted with all of the MAbs indicating a possible definitive host for the parasite.

Knowledge, attitude and practice regarding diabetic retinopathy screening and its management among diabetic patients at a private hospital of Riyadh, Saudi Arabia

PURPOSE: We present the KAP levels and the determinants for diabetic retinopathy (DR) screening and management at a private hospital in Riyadh, Saudi Arabia. METHODS: A chart review was performed of DM patients to collect the demographics and diabetes related information in June to December 2017. A close ended questionnaire was used that queried knowledge (7), attitude (5) and practice for DR screening (7). RESULTS: Two hundred participants were interviewed half from endocrinology unit and half from the eye clinic. An excellent knowledge of the ophthalmic effects of diabetes was noted in 91 [45.5% (95% Confidence Interval CI 38.6–52.4) of participants. Thirty-eight [19% (95% CI 13.6–24.4)] participants had a positive attitude. None had an excellent grade of practice and poor practice was noted in 168 [74% (95% CI 78.9–89.1)] participants. Longer duration of DM (P=0.07) and systemic complications (P=0.06) were associated with good knowledge. Attitude was not significantly associated with any determinants. Good practice was associated with the presence of systemic complications of DM (P<0.01) and those recruited to the eye clinic (P= 0.06). Only 35% of patients had undergone an annual DR screening. Only 4 patients had a history of laser treatment. CONCLUSION: The KAP of diabetic patients regarding DR screening and management is less than desired. Establishing protocols and public health promotion activities directed at early detection and management are urgently needed in private sectors of Saudi Arabia.
Decreased VEGF and Cyclin D1 Genes Expression Enhances Chemosensitivity of Human Squamous Cell Carcinoma Cells to 5-Fluorouracil and/or Mesenchymal Stem Cells-Derived Microvesicles

Background: Among the most common oral cancers is oral squamous cell carcinoma which has high rates of mortality. 5-flurouracil (5-FU) is a widely used chemotherapeutic agent for treatment of head and neck cancers. However, its use has many limitations due to its well- known side effects. Thus, in the current study we aimed to investigate the chemosensitivity of squamous cell carcinoma cells to 5-FU and/or mesenchymal stem cells-derived microvesicles via H&E histopathological examination, in addition to detection of vascular endothelial growth factor (VEGF) and cyclin D1 (CD1) genes’ expression through quantitative RT-PCR analysis. Material & Methods: Human squamous cell carcinoma cell line (SCC152) was treated by 5-FU or Microvesicles or their combination for 24 and 48 hours. Histopathological examination through H&E stain as well as quantitative RT-PCR analysis, for gene expression of VEGF and CD1, were performed. Finally, statistical analysis of the obtained data and correlation between VEGF and CD1 genes’ expression among different groups were performed. Results: Regarding the histopathological results, the combination group, as compared to 5-FU or microvesicles treated groups, showed the most obvious improvement where numerous apoptotic bodies were observed at 24hrs, being markedly increased at 48hrs of culture, while viable cells were rarely seen. Concerning the qRT-PCR results, the combination group showed significant decrease in genes’ expression of both VEGF and CD1 than the 5-FU or microvesicles treated groups. Furthermore, correlation between VEGF and CD1 genes’ expression revealed a very good positive correlation.Conclusions: it was concluded that the combined use of microvesicles and 5-FU resulted in enhanced chemosensitivity of squamous cell carcinoma cells more than the use of either 5-FU or microvesicle alone. In addition, down regulation of VEGF gene expression was associated with decreased CD1 gene expression.

Soil properties alter plant and microbial communities to modulate denitrification rates in subtropical riparian wetlands

The capacity of riparian wetlands to remove nitrogen from upland runoff through the denitrification process is mainly controlled by soil properties and biological communities. However, the pathways or mechanisms by which soil properties and biological communities may regulate riparian denitrification rates are still largely unknown. Here, we measured the potential and unamended denitrification rates in sediments from riverine wetlands along a nitrogen‐rich river in subtropical China. We also investigated the plant richness, vegetation cover, and abundance of denitrifying microorganisms in wetland soils. The results show that both potential and unamended denitrification rates presented strong seasonality, and were found to be significantly associated with nitrogen concentration in soils, implying that denitrification process in riparian wetlands is probably nitrogen limited. Moreover, potential and unamended denitrification rates were positively related to denitrifier abundance, plant richness, and vegetation cover. Using structural equation modeling, we found that moisture and nitrogen concentration could influence denitrification rates directly; the indirect effects of these factors on denitrification rates mediated through modulating the structure of plant and microbial communities. These findings suggest that denitrification rates and nitrogen removal capacities in riparian wetlands are jointly modulated by soil properties and biological communities.
OPTIMISM/PESSIMISM AS A MEDIATOR OF SOCIAL STRUCTURAL DISPARITIES EFFECTS ON PHYSICAL HEALTH AND PSYCHOLOGICAL WELL-BEING: A LONGITUDINAL STUDY OF HOSPITALIZED ELDERS

by CHRISTOPHER J. BURANT Elders hospitalized for acute episodes of illness are often at risk for functional decline that can lead to “The Disablement Process” (Verbrugge and Jette, 1994). Studies show that one's level of optimism and pessimism impacts the recovery from chronic illnesses. The current study tests optimism and pessimism’s affect on recovery from acute conditions in 944 hospitalized elders at a large Midwest academic university affiliated hospital. This study contributes to the literature in four primary ways. First it expands the research on the relationship between optimism/pessimism and psychological well being and physical health in hospitalized elders. Second, the current study is the first to empirically test social structural disparities as antecedents to optimism and pessimism. Third, this study provides a more rigorous test concerning the dimensionality of the LOT. Finally, the present study uses a recently developed autoregressive latent trajectory (ALT) models to conduct a sophisticated analysis of the trajectory of recovery and the causal relationships between physical health and
health-related quality of life among older patients treated with complete prostheses

Introduction. Prosthetic rehabilitation of edentulous patients exerts an indisputable influence on their sense of oral health-related quality of life (OHRQoL). This study examines which particular OHRQoL aspects pose the biggest challenge in terms of improvement upon the conclusion of a complete prosthesis adaptation period. Basic research design. Patients were examined at the Gerostomatology Clinic, Poznań University of Medical Sciences, in 2012–2013. Participants. The research involved 76 edentulous people over 60 years of age, of whom 66 returned for post-treatment check-ups after three months. Interventions. Oral health-related quality of life was examined, using the General Oral Health Assessment Index, prior to prosthetic restoration and following a three-month adaptation period. Results. Within the scope of an OHRQoL assessment, the examined patients scored the fewest points with regard to problems caused by mastication (Q2), unease at the appearance of their dentition (Q9), and discomfort experienced while eating (Q5). Following the three-month adaptation period, the highest percentage increase was observed in terms of the patient’s satisfaction with the looks of their dentition (Q7), while more than 10% of the patients experienced the negative impact of eating-related problems on their daily lives (Q1, Q2, Q5). Conclusions. Prosthetic treatment of edentulous patients using conventional complete prostheses significantly improves patients’ oral health-related quality of life. Discomfort caused by problems with mastication can be observed among 10% of the examined patients.
Comparing the Rates of Misconduct Between Private and Public Prisons in Texas

Mass incarceration has led to an increased reliance on private prisons. Yet, there is little evidence regarding the extent to which public safety and misconduct patterns differ across private versus public prisons. Combining data from prisoners in the State of Texas within a counterfactual research design, the current study examines differences in the likelihood of engaging in misconduct among comparable male inmates sentenced to a private over a public prison unit. Findings indicate there are no significant differences in the amount of misconduct committed by inmates in either public or private institutions—with the exception of physical violence. Inmates assigned to private facilities were 10% less likely to engage in institutional violence compared with similarly situated inmates assigned to public facilities.
EXTENDED SCOPE PHYSIOTHERAPISTS: HOW OFTEN DOES THEIR CLINICAL DIAGNOSIS AGREE WITH THE MRI SCAN?

Objective: To determine whether extended scope physiotherapists (ESP’s) in spinal clinics are able to accurately assess and diagnose patient pathology as verified by MRI findings. Methods: This is a prospective study of 318 new spinal outpatients assessed and examined by one of two spinal ESP’s. 76 patients (24%) were referred for an MRI scan. At the time of request for MRI scan the likelihood of specific spinal pathology correlating with the MRI scan was noted on a four point scale dividing the patients into 4 groups: Group 4 = Very high suspicion of pathology (n=41) Group 3 = Moderate suspicion of pathology (n=21) Group 2 = Some suspicion of pathology (n=10) Group 1 = Pathology unlikely but scan indicated eg thoracic pain (n=4). Results: Of the 76 patients referred for an MRI scan, 54 (71%) had an MRI scan result that would correlate with the clinical picture. Looking at the percentage of scans correlating with the clinical picture for each of the 4 groups: Group 4: 88% Group 3: 67% Group 2: 40% Group 1: 0% Conclusion: Dividing the patients into groups by clinical suspicion is essential for evaluating a clinician’s ability in spinal assessment. Further evaluation of Consultants, Fellows and Specialist Registrars is on going. This type of study could form a basis for competency measures for staff development and training if they are undertaking extended roles.
The Current Status of Prescribing Psychologists: Practice Patterns and Medical Professional Evaluations

Despite ongoing controversy surrounding prescriptive authority for psychologists, few studies have been conducted on the practices or acceptance of prescribing psychologists. The current study had three aims. The first was to evaluate how prescribing psychologists are perceived by themselves and by their colleagues in various medical professions. The second aim was to understand the practice patterns of prescribing psychologists, while the last was to explore factors associated with perceptions of prescribing psychologists among medical professionals. Thirty prescribing psychologists and 24 of their medical colleagues completed surveys evaluating perceptions and practices of prescribing psychologists. Results demonstrated that prescribing psychologists were overwhelmingly perceived positively by their medical colleagues across various domains. Basic elements of the practice of the prescribing psychologist are described. Conclusions, limitations, and suggestions for further research are discussed.
Staff Nurses' Perceptions of Rapid Response Teams in Acute Care Hospitals

The purpose of the present study were to (a) explore the relationship between the frequency of use of Rapid Response Teams (RRTs) by hospital staff nurses and the support received from RRTs; (b) to investigate staff nurses’ perceptions of their individual level, group level and organizational level learning as a result of single or multiple exposures to the RRT; (c) to identify predictors of learning outcomes and (d) to identify overall impressions and advantages and disadvantages of the RRT. A mail survey was used to collect data. The response responses rate was 33%, 131 registered nurses responded to the survey (pre-test = 12, study = 119). The results of Pearson r correlation suggest that a high frequency of access of RRTs was positively related to process support (r = .25, p < .01). Also, perceived content and process support from RRTs was positively related to maintenance and building of staff nurses’ mental models regarding patient deterioration pertaining to self, group and organization. Multiple regression analyses show that sociodemographic and independent variables predict organizational learning outcomes (mental model maintenance and building). Overall impressions of the RRTs were high. A content analysis of nurses’ comments indicated that there were more advantages to having the RRTs than disadvantages. This study suggests that RRTs are influential in changing nurses’ perceptions about managing patient deterioration. Training programs for RRTs should include both content and process support, which may enhance building and maintaining mental models.
Hybrid Lead Halide Perovskite and Bismuth-Based Perovskite-Inspired Photovoltaics: An In Situ Investigation

Ink-based semiconductors that come to mind today include conjugated molecules and polymers, colloidal quantum dots, metal halide hybrid perovskites, and transition metal oxides. These materials form an ink (solution/ suspension/ sol-gel) that can be applied and dried in ambient air to form high-quality films for optoelectronic devices. In this study, we will introduce the current understanding of ink-based lead and lead-free hybrid perovskite and perovskite-inspired thin films. Examples will be presented through time-resolved studies of the solidification to link the solidstate microstructure and device figures of merit to the ink’s formulation, drying, and solidification process. The perovskite crystallization kinetics characterized in situ during the solution process indicates an essential role by the inclusion of Cs and K alkali metal cations in perovskite inks. The film and device characterizations indicate the functions of mixed cation and halides in determining the optoelectronic properties. The further sophisticated design of perovskite inks enables significantly optimized charge dynamics, including exciton separation, inter-grain charge transfer, trap density, charge mobility, and charge collection efficiency. The considerably improved optoelectronic properties lead to higher charge collection efficiency and, therefore, better open-circuit voltage and fill factor for the Cs-containing 3D perovskite devices in contrast to the control FAPbI3 one. Recent developments in ink formulation and processing that enable scalable ambient fabrication of high-quality perovskite semiconductor films will also be presented. These findings raise the possibility of developing more controlled perovskites for systematically addressing both charge dynamics and degradation mechanisms in concert for the timely commercialization of perovskite solar cells.
Corporate governance beyond the shareholder–stakeholder dichotomy: Lessons from Japanese corporations' environmental performance

Although corporate environmental performance (CEP) is determined by corporate governance (CG) typified by board and ownership structures, in‐depth research on stakeholder‐oriented CG is sparse. This study seeks to fill this void and promote an alternative vision of good governance. Japanese corporations have often been criticized for their stakeholder‐oriented practices such as less independent boards and the dominance of stable domestic shareholders. However, these practices are not necessarily problematic if effective monitoring mechanisms are in place. Using a database of Japanese listed corporations over 2012–2015, this study shows that both board size and composition enhance CEP, confirming the advisory function of boards. Contrastingly, foreign blockholders, who are expected to play a monitoring role, significantly constrain CEP. Japanese corporations are evolving toward a hybrid CG that aims to narrow the shareholder–stakeholder divide, and the findings will offer useful lessons for the modification of shareholder‐oriented CG.

Advancing employee’s innovative work behaviors in the workplace

Despite the mounting evidence that leadership can fuel the innovation behavior of employees, yet no study considered the psychological state of employees in such a relationship while Psychology is the primary root of human feelings and behavior. In this regard, this study uses the integrative approach of transformational leadership theory and positive psychology to uncover the pivotal role of positive psychological capital (PsyCap) and perceived effort-reward fairness in the relationship between transformational leadership (TFL) and employee’s innovation behavior. Data collected from 14 banking institutions operating in Rwanda (412 total respondents) were analyzed using structural equation modeling and findings support our hypothesized model
