Drag Prediction of Engine -Airframe Interference Effects Using Unstructured Navier -Stokes Calculations

Navier-Stokes calculations on hybrid grids using the TAU software of the MEGAFLOW project are performed to compute engine installation drag for the DLR, German Aerospace Research Center, F6 transport aircraft configuration at cruise flight conditions with conventional and with very-high-bypass-ratio nacelles at three and two different locations, respectively. The results are verified by a comparison with experimental data from different wind-tunnel campaigns carried out with Office National d'Etudes et de Recherches Aerospatiales. Numerical discretization errors are reduced by several steps of grid adaptation, resulting in grid densities up to 8.4 x 10 6 nodes. It is demonstrated that the installation drag of the different configurations, which vary only a few drag counts (10 -4 ), can be computed consistently, although the total drag forces are predicted lower than results of experiments. Successive grid refinement leads to a decrease of the differences between calculated and measured installation drag
Characteristics of SOI FET's under pulsed conditions

A system for measuring output characteristics of FET's using nanosecond pulses, instead of dc voltage and current measurement, is described. The measurement system is used to obtain the I-V characteristics of silicon-on-insulator (SOI) FET's without the degradation resulting from self heating. Use of the technique to study partially depleted SOI FET's with floating bodies shows that under pulsed conditions, their output curves have a history dependence. The physical mechanisms responsible for the history dependence are explained. Further understanding of the physical mechanisms is given by examination of single-shot pulse measurements. The role of transient and time-dependent phenomena in determining I-V curves is elucidated.
The Academic Buoyancy Scale: Measurement Invariance across Culture and Gender in Egyptian and Omani Undergraduates

The academic buoyancy scale (ABS) is one of the most widely used instruments for measuring academic buoyancy. To obtain meaningful and valid comparisons across groups using ABS, however, measurement invariance should be ascertained a priori. To that end, we examined its measurement invariance, validity evidence based on relations to other variables, and score reliability using categorical omega across culture and gender among Egyptian and Omani undergraduates. Participants were 345 college students: Egyptian sample (N=191) and Omani sample (N=154). To assess measurement invariance across culture and gender, multiple–group confirmatory factor analysis was performed with four successive invariance models: (a) configural, (b) metric, (c) scalar, and (d) residual. Results revealed that the unidimensional baseline model had adequate fit to the data in the full sample. Moreover, measurement invariance was found to hold across culture but not across gender and consequently the ABS could be used to yield valid cross-cultural comparisons between the Egyptian and Omani students. Conversely, it cannot be used to yield valid inferences related to comparing gender groups within each culture. Validity evidence based on relations to other variables was supported by the significantly moderate correlation between ABS and academic achievement (GPA; r =.435 and r = .457, P < .01) for the Egyptian and Omani samples, respectively. With regard to score reliability, categorical omega coefficients were moderate across both samples. Educational and psychological implications, limitations and suggestions for improving the scale are discussed.
Chromogenic in Situ Hybridization for Human Cytomegalovirus-DNA Detection in Tissue Subsets with Prostatic Adenocarcinoma and Benign Hyperplasia

Human cytomegalovirus (HCMV) infects a wide range of human cells, resulting in both benign and malignant tumors. In the last few decades, proteins and/or nucleic acids of the virus were found to be often highly expressed in in patients with basal cell hyperplasia and prostatic neoplasia. This research aimed to unravel the rate of HCMV infections among prostatic tissue subsets from Iraqi patients with adenocarcinoma and benign hyperplasia. One hundred, formalin-fixed and paraffin embedded prostatic tissues were obtained from 40 tissue samples collected from different grades of prostate carcinoma; 40 from benign prostatic hyperplasia and 20 from apparently healthy prostatic tissues. These tissue specimens were collected from the archives of different public and private histopathological laboratories in Baghdad. Detection of HCMV-DNA was achieved by a highly sensitive version of chromogenic in situ hybridization technique. The signals of chromogenic in situ hybridization reactions for HCMV-DNA detection in prostatic adenocarcinoma tissues were found in 65% (26 out of 40) of the tissues, whereas in BPH (Benign Prostatic Hyperplasia), HCMV-DNA was detected in 57.5% (23 out of 40) of the tissues, and in the healthy control group in 25% (5 out of 20) of the tissues. The highest percentage of positive- HCMV- DNA-CISH reactions (57.5%) was found in prostatic adenocarcinomatous tissues that showed poor differentiation. Our results could show that HCMV might contribute to the development of the studied subsets of prostatic adenocarcinoma and benign prostatic hyperplasia.
Brahmin Left Versus Merchant Right: Changing Political Cleavages in 21 Western Democracies, 1948-2020

This article sheds new light on the long-run evolution of political cleavages in 21 Western democracies. We exploit a new database on the socioeconomic determinants of the vote, covering over 300 elections held between 1948 and 2020. In the 1950s and 1960s, the vote for social democratic, socialist, and affiliated parties was associated with lower-educated and low-income voters. It has gradually become associated with higher-educated voters, giving rise in the 2010s to a disconnection between the effects of income and education on the vote: higher-educated voters now vote for the “left,” while high-income voters continue to vote for the “right. ” This transition has been accelerated by the rise of green and anti-immigration movements, whose distinctive feature is to concentrate the votes of the higher-educated and lower-educated electorates. Combining our database with historical data on political parties’ programs, we provide evidence that the reversal of the education cleavage is strongly linked to the emergence of a new “sociocultural” axis of political conflict.
Characterization and energy-based model of the magnetomechanical behavior of polycrystalline iron–gallium alloys

The actuation and sensing behavior of a typical polycrystalline Fe81.6Ga18. 4 alloy sample grown using free stand zone melt (FSZM) manufacturing processes was characterized and its cross-section texture was determined at three transverse stations using electron back-scattering diffraction (EBSD). An attempt was made to model the actuation and sensing behavior of the polycrystalline magnetostrictive sample from its cross-section texture by treating the polycrystal as composed of multiple grains of single crystals, each with a different orientation to the loading axis. The polycrystalline magnetomechanical behavior was modeled as the sum of the volume fraction weighted single-crystal behavior along the [100], [110], [210], [310], [111], [211] and [311] directions, which are modeled using the energy-based approach discussed in Armstrong (1997 J. Appl. Phys. 81 2321) and Atulasimha (2006 PhD Thesis Aerospace Engineering, University of Maryland).
Transmission-Line Properties of a Round Wire in a Polygon Shield

A family of transmission lines is based on a round wire in a cylindrical shield of polygon cross-section. There is presented a simple formula which gives a smooth transition between the extremes of a small wire and a wire near contact. The same formula is adapted for different shapes by entry of different constants depending on the number of shield planes and the degree of symmetry. The formula is reversible for synthesis or analysis by explicit expression of either shape ratio or wave resistance in terms of the other. For comparison in the transition region, there is computed for each shape a close approximation by the method of images.
HEALTHCARE PROVIDER PATIENT NONVERBAL COMMUNICATIVE BEHAVIOUR ON DIABETES MELLITUS MANAGEMENT PRACTICES IN SELECTED HOSPITALS IN KENYA

Purpose: To examine the effect of healthcare provider patient communication nonverbal communicative behaviour on diabetes mellitus management practices in selected hospital in Kenya. Methodology: This was a causal comparative research design study with application of quantitative methodology. The study was carried out at Kenyatta National Hospital (KNH) and MP Shah Hospital. Systematic random sampling was used to sample patients. 400 participants were involved in the study and comprised 313 patients at KNH and 87 patients at MP Shah Hospital studied between the months of February 2019 and November 2019. The researcher administered questionnaire was used to collect data. The results were summarized using percentages and means or medians for categorical and continuous data respectively. Comparisons were done using chi square test of association of categorical variables and independent t-test for comparison of means. Linear regression and ANOVA were used to test for associations and hypothesis between healthcare provider patient nonverbal communicative behaviour (NVCB) and diabetes mellitus management practices (DMMPs). Findings: The rating of nonverbal communicative behavior was significantly higher at MP Shah Hospital than at KNH, p=0.010. Nonverbal communicative behavior had positive significant effect on diabetes mellitus management practices in Kenya [β=0.15, (95% CI 0.03, 0.27), p=0.016] with similar outcome at KNH [β=0.20, (95% CI 0.08, 0.33), p=0.002] and not at MP Shah Hospital [β=0.03, (95% CI 0.37, 0.42), p=0.899]. Thus, the null hypothesis was rejected in Kenya; the null hypothesis was rejected at KNH; the null hypothesis was not rejected at MP Shah Hospital. Therefore, there was significant effect of NVCB on DMMPs in Kenya, at KNH and not at MP Shah Hospital. Unique contribution to theory, practice and policy: Nonverbal communicative behaviour was responsible for improved performance in diabetes mellitus management practices among patients in Kenya and at KNH. At MP Shah Hospital, NVCB was not responsible for improvement in the DMMPs. The findings reinforce uncertainty reduction and communication accommodation theories basis in the dyadic interaction between patients and healthcare providers. Therefore, NVCB needs to be well conceptualized and incorporated at the health ministry and medical training institutions to equip medical workers with the required communication skills.

Self-Oscillating 150 W Switch-Mode Amplifier Equipped with eGaN-FETs

This paper discusses the effect of flux modulation in the electrodynamic loudspeaker with main focus on the effect on the force factor. A measurement setup to measure the AC flux modulation with static voice coil is explained and the measurements shows good consistency with FEA simulations. Measurements of the generated AC flux modulation shows, that eddy currents are the main source to magnetic losses in form of phase lag and amplitude changes. Use of a copper cap shows a decrease in flux modulation amplitude at the expense of increased power losses. Finally, simulations show that there is a high dependency between the generated AC flux modulation from the voice coil and the AC force factor change.
Competitiveness of Small-Medium, New Generation Reactors: A Comparative Study on Capital and O&M Costs

Smaller size reactors are going to be an important component of the worldwide nuclear renaissance. An inappropriate application of the economy of scale would label the small-medium size reactors as not economically competitive with larger plants because of capital costs ($/kWe) and O&M costs ($/kWh) that would appear to be significantly higher. However, the economy of scale applies only if the considered designs are similar, which is not the case here, since the small size allows original design solutions not accessible to large size reactors. In the paper the historical trend of capital costs vs. plant size is estimated from literature, and a reference exponent factor for the economy of scale for the light water reactor is derived. Then the paper identifies and briefly discusses the various factors which, beside size, contribute in differentiating the capital cost of smaller reactors with respect to large reactors. In this reference frame the evaluation for of the following factors is provided: · design characteristics · modular build · multiple units · accelerated learning in construction · operation, and shorter construction time. The IRIS reactor is used as the example of small modular reactor (SMR), but the analysis and conclusions are applicable to the whole spectrum of small nuclear plants. The results show that when all these factors are accounted for in a set of realistic and comparable configurations, and with the same power installed in the site, the capital costs of small and large plants installations are practically equivalent. Considering the O&M cost the paper shows how the plant size is not the only and fundamental cost driver. In fact there is a range of other factors (e.g. location, regulatory issues, capacity factor, plant obsolescence and number of reactors on a site) able to influence the annual O&M cost for a specific plant. The paper provides a preliminary evaluation of these factors by historical analysis of reactors built in the United States, concluding, also in this case, that when all the factors are considered the difference between the average cost ($/KWh) of Large Size vs. SMR is about 20% less than would be expected.
Evaluation of taxonomic and neural embedding methods for calculating semantic similarity

Abstract Modelling semantic similarity plays a fundamental role in lexical semantic applications. A natural way of calculating semantic similarity is to access handcrafted semantic networks, but similarity prediction can also be anticipated in a distributional vector space. Similarity calculation continues to be a challenging task, even with the latest breakthroughs in deep neural language models. We first examined popular methodologies in measuring taxonomic similarity, including edge-counting that solely employs semantic relations in a taxonomy, as well as the complex methods that estimate concept specificity. We further extrapolated three weighting factors in modelling taxonomic similarity. To study the distinct mechanisms between taxonomic and distributional similarity measures, we ran head-to-head comparisons of each measure with human similarity judgements from the perspectives of word frequency, polysemy degree and similarity intensity. Our findings suggest that without fine-tuning the uniform distance, taxonomic similarity measures can depend on the shortest path length as a prime factor to predict semantic similarity; in contrast to distributional semantics, edge-counting is free from sense distribution bias in use and can measure word similarity both literally and metaphorically; the synergy of retrofitting neural embeddings with concept relations in similarity prediction may indicate a new trend to leverage knowledge bases on transfer learning. It appears that a large gap still exists on computing semantic similarity among different ranges of word frequency, polysemous degree and similarity intensity.
Optimal prestressing and configuration of stayed columns

A steel column that is reinforced by prestressed stays generally has an increased strength in axial compression. In the past, greater emphasis was placed on obtaining its higher critical buckling load. However, detailed knowledge of the post-buckling behaviour is important to ensure the safety and the efficiency of the structure. Although previous work revealed that the optimal design should be determined with the post-buckling response, the actual values of the optimal prestress had not been previously evaluated. The present work examines the issue of the true optimal prestress for stayed columns through proposed structural optimisation indicators involving both instability and material quantity measures. Non-linear finite-element analysis was performed to investigate the non-linear buckling behaviour, which gives values for these indicators. Through a comparison of these values, suggestions for the configurations for improving the structural efficiency are presented.
Testicular Cancer Knowledge and Viewpoints of American Men

Abstract Introduction: We sought to better understand the baseline knowledge and practices of the general population regarding testicular cancer (TC) and testicular self-examination (TSE) in an effort to understand whether current screening guidelines reflect their viewpoint. The U.S. Preventive Services Task Force (USPSTF) currently recommends against TSE for TC screening due to a lack of data to support a benefit. Early detection of TC may reduce the required burden of therapy and associated long-term toxicities. Methods: This was a cross-sectional survey study. Participants (median age 33 years, IQR 28–39) were recruited via Amazon Mechanical Turk, a validated crowdsourcing platform used to recruit minimally compensated participants. Results: A total of 250 men rated themselves as “somewhat unknowledgeable” about TC, with no respondents considering themselves “very knowledgeable. ” Only 26.4% of men knew that TC was curable most of the time. Despite 90.8% of men feeling that their doctor had some role in discussing TC/TSE, only 17.2% had discussed these topics with their doctor. Even after being informed of the rationale behind USPSTF recommendations, only 8% of men thought that potential false positives of TSE would be more important than the rare chance of finding early TC. Conclusions: American men do not feel knowledgeable about TC, have a favorable attitude toward TSE and want their doctor to discuss these topics. Shared decision making regarding TC screening is warranted given the low risk of harm and patient interest, and continued accrual of data on this topic is necessary given the lack of prospective work to date.
Bacterial Hazards and Critical Control Points in Goat Processing at a Typical Tropical Abattoir in Ibadan, Nigeria

This study assessed bacteria hazards in goat processing line. Goat meat has become an important source of protein to the teaming Nigerian populace. Unhygienic processing of carcasses and inadequate sanitary conditions of the abattoir poses health risks to consumers. Enterobacteriaceae count and Total Aerobic Plate Counts were assayed along the processing line and facilities used in goat processing. Enterobacteriaceae count on goat carcasses increased from 12.70 logcfu/cm 2 before evisceration to 13.72 logcfu/cm 2 after singeing, while the Total Aerobic Plate Counts increased from 13.45 logcfu/cm 2 for tables after wash to 14.01 logcfu/cm 2 for tables or knives before wash and carcass after wash. These counts exceeded international limits (WHO/European Commission). The microbial assay showed a significant difference in Enterobacteriaceae count (p 0.05). A positive correlation (r 2 = 0.0528) ensued between the Enterobacteriaceae count and Total Aerobic Plate Counts. Important Critical Control Points (CCPs) include: goat's skin after singeing, evisceration, cutting (knife before use), display table before use and waste water generated during the processing. The findings in this study suggest that processed goat carcasses from the abattoir under study will pose serious health hazard to consumers. The public health implications and need to implement Hazard Analysis Critical Control system in goat carcass processing to ensure provision of wholesome meat for the human populace is therefore emphasized.
Improvement of a Riveting Process Capability with Application of Tools and Methods of the Quality Management

Assessment of a process capability is an important area of the quality management. Quality of produced outputs depends on the quality of the process, in which product characteristics are formed. In considering the capability of the process, the ability of the process should be determined to provide the required quality of products. The required product quality has to meet customer requirements and expectations. For determination of process capability are used methods, which are based on comparing variability of selected product quality characteristics. The smaller the variability of the input factor is, the better is the process capability and therefore a better quality of product is produced. Improvement of process capability and reducing the variability of the product quality characteristics can be achieved by means of applying of statistical methods. Standards for the quality management system require the need of statistical methods application as well as other tools and techniques for improvement in business practice. It is necessary to use statistical methods in measuring, monitoring and process improvement. So can be determined the process variability, identified common and special causes of variability and in consequence to propose corrective actions. The paper describes first theoretical characteristics of capability assessment methods and tools in continuous improvement in industry praxis. With application of chosen statistical methods has been improved capability of the riveting process of clutch disk.
Rainfall-Induced Landslide Thresholds Development by Considering Different Rainfall Parameters: A Review

This paper reviews the development of landslide thresholds from the perspective of rainfall and climate patterns. For certain, geology, morphology, lithology, etc., contribute to the initiation of the mass movement. However, the role of rainfall as the triggering mechanism of the landslide is vital as well. It has been proven by many researchers from various studies worldwide that have proposed the rainfall thresholds by utilising different rainfall parameters. The outcome of their studies is interesting, since different regions have diversified patterns of rainfall that produce a variety of threshold models. Therefore, from various published papers on rainfall thresholds, this paper studied the variety of rainfall parameters that have been utilised in establishing the rainfall threshold for landslide prediction. Instead of providing a better understanding regarding the application, this review aimed to cultivate the following study for deriving rigorous parameters for the purpose of sustainable findings.
