Impact of Additive Manufacturing on Internal Cooling Channels With Varying Diameters and Build Directions

The use of additive manufacturing (AM) processes, such as direct metal laser sintering, provides the design freedom required to incorporate complex cooling schemes in gas turbine components. Additively manufactured turbine components have a range of cooling feature sizes and, because of the inherent three-dimensionality, a wide range of build angles. Previous studies have shown that AM built directions influence internal channel surface roughness that, in turn, augment heat transfer and pressure loss. This study investigates the impact of AM on channel feature size and builds direction relative to tolerance, surface roughness, pressure losses, and convective cooling. Multiple AM coupons were built from Inconel 718 consisting of channels with different diameters and a variety of build directions. An experimental rig was used to measure pressure drop to calculate friction factor and was used to impose a constant surface temperature boundary condition to collect Nusselt number over a range of Reynolds numbers. Significant variations in surface roughness and geometric deviations from the design intent were observed for distinct build directions and channel sizes. These differences led to notable impacts in friction factor and Nusselt number augmentations, which were a strong function of build angle.
Online Meditation Program Builds Resilience and Competencies Among Social Work Students Working With Older Adults

ABSTRACT This article reports the results of a study on the impact of an online meditation (OMP) program in building resilience and geriatric social work competencies among postgraduate social work students across contexts. The OMP was fairly effective (Cohen’s d range=4.84–5.49, p≤.012), and students who participated in it exhibited greater resilience and geriatric social work competencies compared to the wait-list control group. Posttest resilience scores were higher for female students and Christians. Female students studying in the United States and Sweden with non-social-work subjects at the undergraduate level and doing field placement in assisted living settings demonstrated greater geriatric social work competencies posttest. Adherence through regular attendance of the OMP lessons and self-practice mediated the relation between sociodemographic predictors and outcomes. The OMP is a useful addition in the postgraduate field training curriculum with some refinements for male students from different cultures with a social work undergraduate degree and doing fieldwork in community or hospice settings.
Identification of volatile organic compounds extracted by headspace solid‐phase microextraction in specialty beers produced in Brazil

Beer is a very complex mixture, being an alcoholic beverage obtained by fermentation processes. The consumption and production of specialty beers in Brazil have increased in the past years; however, most Brazilian brewers still depend on imported commercial starter yeast strains and raw materials. Our data also indicate that volatile profile of Brazilian beers is more influenced by raw materials. The analysis of volatile compounds in beer is important for its quality control, and the presence of aromatic substances is related to the beverage acceptance and quality. In this study, headspace solid phase microextraction in combination with gas chromatography coupled to mass spectrometric detection was used for the identification of the volatile organic compounds in 30 samples of Brazilian Pilsen and ale beers. Ninety-nine volatile compounds were identified and grouped into ketones, terpenes, esters, higher alcohols, aldehydes, fatty acids, hydrocarbon and other minority compounds. Analysis of the principal components showed that the majority of specialty beers have similar chemical characteristics, their volatile profile being characterized mainly by esters and higher alcohols. Additional studies are necessary to better characterize Brazilian specialty beers; however, our results open perspectives for future research of possible indicators and markers that may serve for the purposes of certification, as well as quality control of the beverage.

Self-incompatibility (S) genotypes of cultivated sweet cherries – An overview update 2020

The fertility in sweet cherry is determined by a gametophytic self-incompatibility system, controlled by a multi-allelic S locus who prevents self-pollination. The fertilization is controlled by the interaction of an S allele specific ribonuclease (S-RNase) in the style with a pollen S specific F-box protein gene (SFB). Knowledge about the S genotype of sweet cherries is very important for cherry growers and breeders. In the last years molecular markers have been developed to distinguish the S alleles in sweet cherries. In the new update from October 2020 a total of 63 incompatibility groups in 1483 sweet cherries have been defined. 26 sweet cherries have a unique combination of S alleles and were described as universal donors and placed in the incompatibility group 0. Additionally, there exist 91 self-compatible sweet cherries, called group SC. A total of 22 different S alleles are described in the cultivated sweet cherries up to date. These are the S alleles S1, S2, S3, S4, S5, S6, S7, S9, S10, S12, S13, S14, S16, S17, S18, S19, S21, S22, S24, S27, S30, S37. The goal of this work is to summaries all known data of the S alleles in cultivated sweet cherries. In Table 1 the S genotypes of all studied sweet cherries are described. Furthermore it includes information about the parentage if they are known. Table 2 gives an overview about all the detected incompatibility groups. The groups are sorted according to the group numbers and the S allele numbers, respectively. In Table 3 all genotypes of the incompatibility group 0 with a unique S genotype are listed. Table 4 includes all known self-compatible sweet cherries. All references to the information of the S genotypes are listed in a file named 'References'. The present update needs to be further improved with all new S alleles data of sweet cherries. In addition, all new information about the parentage is very important for the breeding research. Please send all new or corrected data to the S alleles and the parentage of sweet cherries to mirko.schuster@julius-kuehn.de. An update of the S allele overview will take place in the next years.
The Effect of Wechat-Based Training on Improving the Village Doctors’ Knowledge of Tuberculosis Management: A Pre-And-Post Intervention Study from China

Background: In China, village doctors played a crucial role in TB cases referral and management. The current study aimed to evaluate the effect of WeChat-based training program on improving the village doctors’ knowledge on TB management.Methods: A One-year WeChat-based training was conducted by means of releasing original contents (in forms of text, poster, video or cartoon), through WeChat subscription account (WeChat SA) once a week. Pre-and post-training offline tests were hold using the same self-administered questionnaire to evaluate the training effect.Results: A total of 467 village doctor were included in the study. During the training, sixty original articles were posted through WeChat SA. With respect to the two tests, the median score increased from 50 (40.0-60.0) to 60 (53.0-70.0) (p<0.001) after training. The median scores were always higher after training no matter what kind of article contents and forms. In addition, the effectiveness of such training was found to be influenced by gender and education level.Conclusions: Our results indicated that WeChat-based training could partly improve the knowledge of village doctors on TB management. It is worthy to explore more effective new media-based training methods that might promote TB control work in rural China.
Phenotypic Detection of Macrolide-Lincosamide-Streptogramin Resistance among Staphylococcus aureus and Staphylococcus epidermidis in Baghdad, Iraq

Introduction: Staphylococci emerged as the most frequent nosocomial and community-acquired pathogens. Macrolide-lincosamide-streptogramin (MLS) antibiotics resistance was increasing among Staphylococcus aureus and Staphylococcus epidermidis (S. epidermidis) isolates. Objective: In the present study, the aim was to detect the phenotypic resistance pattern of MLS (constitutive and inducible) among S. aureus and S. epidermidis isolated from Iraqi patients. Methods: A total of 120 staphylococcal isolates (60 S. aureus and 60 S. epidermidis) were isolated from urine, wound swab, blood, and sputum specimens, then specified by the VITEK 2 system. Whole isolates were investigated by the disk-diffusion method against many antibiotics, then they were checked for the MLS phenotype by the D-zone test. Results: Out of 60 S. aureus isolates and 60 S. epidermidis, the isolation rates from wound, urine, blood, and sputum were 66.6 and 50%, 16.7 and 26.7%, 11.7 and 18.3%, and 5% for each species, respectively. The higher frequency rates of resistance were showed against erythromycin, clindamycin, and streptomycin, for both S. aureus with 83.3, 53.3, and 83.3%, respectively, and S. epidermidis with 73.3, 45, and 76.7%, respectively. Constitutive MLS resistance phenotype (MLSc) was shown in 32 isolates (53.3%) of S. aureus and inducible MLS resistance phenotype (MLSi) was noted in 16 isolates (26.7%). Conclusion: The current study concluded that the D-zone test must be applied within the routine work of the antimicrobial susceptibility test for staphylococcal isolates, to exclude the false results of staphylococcal isolates sensitivity against clindamycin.

Evaluation of the Hypolipidemic Properties of Cocoa Shell after Simulated Digestion Using In Vitro Techniques and a Cell Culture Model of Non-Alcoholic Fatty Liver Disease

Obesity is closely associated with the increasing prevalence of non-alcoholic fatty liver disease (NAFLD). Due to the lack of proper pharmacological treatments for NAFLD, finding novel ingredients is necessary to reduce its incidence. Cocoa shell is a cocoa byproduct verified as a safe ingredient and a potential source of health-promoting compounds. Hence, this study’s main objective was to evaluate, after an in vitro simulated digestion, the hypolipidemic properties of the residual fraction of cocoa shell flour and the biological activity of the digested fractions of cocoa shell flour and extract in HepG2 cells. An in vitro static digestion (INFOGEST) of cocoa shell flour was used to establish the residual fraction’s capacity to bind cholesterol and bile salts and inhibit lipase. The results showed that digestion promoted the ability to bind cholesterol and bile salts of a residual fraction from a cocoa shell up to 65.2% and 90.5%. Moreover, digestion improved (1.6-fold, p < 0.05) the ability to inhibit lipase activity. The digested fractions of the flour and extract from the cocoa shell (50–250 µg/mL) significantly (p < 0.05) reduced the accumulation of fat (17–42%), triglycerides (9–38%), and cholesterol (11–54%) in HepG2 cells after NAFLD induction with palmitic acid (500 µM). In conclusion, digestion positively impacted the hypolipidemic properties of cocoa shells in vitro and enhanced their biological activity in cell culture models. Since cocoa shells might be used as a safe, novel ingredient to prevent hyperlipidemia and regulate lipid metabolism, future animal and clinical investigations will be necessary to confirm the effects observed.
Validation of reference genes for RT-qPCR in cardiac tissue of rats induced to obesity and diabetes

The validation of reference genes is an essential step for any RT-qPCR analysis. In this way, the present paper aimed to identify and validate reference genes for RT-qPCR in cardiac tissue of rats of the Rattus norvegicus albinus specie, submitted to obesity associated or not to type 2 diabetes mellitus. For this, the metabolic changes were induced at the 42nd day of life and the euthanasia was performed on the 70th day. The heart apexes were collected and destinates for RNA extraction. The RT-qPCR technique was performed in own thermocycler, the efficiency of the primers found by the LinReg software and the stability of the expression of the reference genes in the samples was analyzed by the RefFinder algorithm. The candidates for reference genes were GAPDH, POLR2A, RPL32, and RPL4 and the target gene used to verify the differences in gene expression of candidates for reference genes was CMA1. The obese animals showed a decrease in CMA1 gene expression when compared to the two most stable reference genes. The opposite occurs when it is compared to the two less stable reference genes. The GAPDH and POLR2A genes are the best to normalize the reactions with the samples in question. There is no universal reference gene for all situations, which requires systematic validation for each situation. The use of unvalidated reference genes may compromise the interpretation of the expression of the target genes, which would prevent the reflection of the actual situation.
To engage or not to engage in organisational citizenship behaviour: that is the question!

Abstract Organisational citizenship behaviour (OCB) can be defined as discretional, voluntary and useful informal behaviour that is not directly acknowledged by the organisation’s formal reward system. Such behaviour refers to actions that go beyond performing the tasks defined as part of one’s job. Previous studies have shown that organisations that promote OCB can notably improve their productivity and efficiency. It is therefore important to know what causes employees to engage in OCB rather than just limiting themselves to doing what is strictly expected at work. However, it is more important to know why they do not engage in OCB. Using a sample of public prison employees and the fsQCA method, this study examines how the combined effects of organisational characteristics, leadership behaviours and individual characteristics lead to the absence of OCB. The results indicate that the absence of affective commitment, or job satisfaction, or interactional justice is a necessary condition for the absence of OCB. Four conditions are identified as sufficient, and the absence of affective commitment and the presence of laissez-faire leadership are found to be the most relevant conditions for the absence of OCB. Managerial implications and directions for future studies are discussed at the end of the paper.
Liquidity Commonality and its Pricing: Evidence from Firms in Supply Chain Networks

This paper investigates how economic links from customer-supplier relationships affect liquidity commonality and its pricing. I show that a stock's liquidity co-moves with liquidity of its economically linked stocks and this liquidity commonality decreases with the level of information asymmetry on the stock. A long-short portfolio from the high-minus-low liquidity commonality with economically linked firms yields economically and statistically significant average returns, and these returns cannot be explained by majorly known systematic risk factors. The results imply that supply-chain networks are another important channel for liquidity risk.
The Impact of Sentiment on Emerging Stock Markets

For five leading emerging economies: China, India, Russia, Indonesia and South Korea, we show that existing sentiment variables-both direct (Consumer Confidence Index) and indirect (Baker-Wurgler Index)-are insignificant in explaining respective nations' index returns. We improve upon current techniques by using modified sentiment extraction as proposed in Anand et al. [2020] to study the impact of central bank speech sentiment on respective stock market indices. We find that central bank speeches do have a significant impact on the stock markets in our sample of emerging countries.
A Preliminary Study of Islamic Financial Well-Being Index

This study aimed to explore the criteria of the financial well-being of the Malaysian workforce to develop a conceptual understanding of the impaired financial well-being of young adults. Concurrently, this study aimed to develop an Islamic Financial Well-Being Index (i-FWB Index) for sustainable financial well-being among Malaysian workers in consideration of recent transformative innovation in Islamic financial services. The orientation of qualitative research fitted the objective of this study, which was to conceptualise on the limited literature on Islamic economic well-being. The utilisation of individual and focus group interviews in gathering expert opinions provided valuable data based on grounded theory to develop a substantive and conceptual analysis. Atlas.ti was used as the software for qualitative analysis to achieve the research objective. Since none has touched on the area of developing financial well-being with the inclusion of religious beliefs, the findings of this study are expected to bridge the gap by providing specific scale in measuring Islamic financial wellbeing index, specifically for Malaysian workers. The originality of this study may contribute to the formation of a new body of knowledge, and enrich the literature sources in the field of scale development that will benefit the academicians.
The Effectiveness of Synchronous Online Flipped Learning in College EFL Reading Course During the COVID-19 Epidemic

The purpose of this study was to examine the effectiveness of synchronous online flipped learning (SOFL) when no one can go to school and merely rely on online learning during the COVID-19 epidemic. According to community of inquiry (CoI), put forward by Garrison et al (2001), only when the three key elements of blended teaching, social presence, teaching presence and cognitive presence reach a high level, can effective learning occur, which were used as the framework of this study. Mixed methods were used to evaluate the effectiveness of SOFL teaching. A total of 60 undergraduates from pre-service English teacher training program participated in an online questionnaire survey and 25 of them voluntarily joined online in-depth interviews. Results showed that the learning effect was improved in SOFL context. Anonymity was found to improve learning in asynchronous online learning while distraction and lack of sustainable attention were found in synchronous online learning session. The findings suggest that instructors may need to have a careful design, strict organization and scientific implementation of synchronous online teaching and learning in order to achieve distinctive teaching effects, and that they may also consider the complex influence factors of synchronous and asynchronous online learning to arouse students’ interest and attention, and meet their learning needs (Wong 2020).
Food Waste and Disposal Behaviour among University Students

Food waste is a crucial and persistent issue globally. The household food waste phenomenon in Malaysia has emerged as increasingly serious with the rapid rise in its generation by domestic households. This study explored youth behaviour toward food waste and its disposal behaviour among the university students of Faculty Business and Management, Universiti Teknologi MARA, Puncak Alam Campus. Factor analysis was applied to identify the underlying factors of food waste and disposal behaviour, while the independent t-test served to examine gender differences regarding the factors. In particular, Pearson’s Chi-square Test of Independence was applied to examine the association between gender and food waste, food planning, and food recycling behaviors. To this end, a self-administrated questionnaire was used to collect data based on the convenience sampling method in which a sample size of 111 respondents were engaged with. Factor analysis successfully identified three factors as a result, namely food disposal, knowledge of food waste, and involvement in preventing food waste. The independent t-test also revealed significant gender differences among the students on food disposal behavior, whereas no significant gender differences were found with the factors of knowledge of food waste and involvement in preventing food waste. Additionally, there was no association between gender and food recycling, food planning, and food waster behaviours, respectively. As such, these findings can increase student participation and commitment to reducing food waste as it is fast becoming an issue for all.
Evaluation of surrounding anatomical structures in implant supported FPD with and without cantilever: An original research

Objective: The aim of this study was to evaluate and compare the status of supporting tissue around implant-supported fixed partial denture with or without cantilever clinically and radiographically during a three year period of follow up. Materials and Methods: one hundred patients who were treated by 300 implants supported fixed partial prosthesis with and without cantilever after at least three years of treatment, were evaluated. Clinical and radiographic indices of plaque index, probing pocket depth, bleeding index and marginal bone loss were measured. Collected data were analyzed by Mann-Whitney, Fridman and repeated-measures ANOVA tests using SPSS software. Results: The overall survival rate of implant supported prosthesis was 95.9% after at least three years of treatment. The success rates of implant supported fixed prosthesis with and without cantilever were 94.6% and 96.8% respectively. Marginal bone loss in the cantilevered fixed prosthesis was significantly more than the second group after two and four years of treatment (P<0.001), however, all the clinical indices were not significantly different. Conclusion: Considering the guidelines of cantilever prosthesis applications, using the cantilevered fixed partial dentures have a similar and comparable prognosis as the traditional implant-supported fixed prostheses.
