The simulation of drop-weight impact test on ramie-eglass hybrid fiber composite for kayoh jaloe wall material
The purpose of this study is to simulate drop-weight impact tests on hybrid fibre composites made of ramie and Eglass, which are used to make the traditional Acehnese boat wall material for jaloe kayoh. Using composites of ramie-Eglass fiber hybrid in the construction of jaloe kayoh wall material will significantly enhance the strength, durability, and sustainability of traditional Acehnese boats. The simulation was carried out using the finite element method approach using the Abaqus software. Three distinct laminate layer configurations—three layers (GRG), five layers (GRGRG), and six layers (GRGGRG)—with alternating Eglass and ramie fibres make up the test specimens. The ends of the specimen are set with fixed support to ensure boundary conditions, which limit all active structural degrees of freedom on all sides of the specimen. According to simulation results, the specimen with six laminate layers, measuring 12.498 mm, had the largest displacement. The specimen with six laminate layers has the highest stress concentration, measured at 560.6 MPa, while the specimen with three layers has the highest strain concentration, measured at 0.023. Its indicating that the lamina variation can influence the structural performance of the jaloe kayoh material. This research contributes to understanding the potential of ramie-Eglass hybrid fiber composites to enhance the safety and durability of traditional vessels such as jaloe kayoh. The implications of the results can serve as a foundation for the development of superior structural materials in the future
Grassroots football club stakeholders' sponsorship: the role of happiness and shared values
Purpose: This research serves to determine causal configurations of corporate social responsibility (CSR) conditions that best influences grassroots football club stakeholders to meet a sponsor's goals through promotional activity. Design/methodology/approach: The research uses a case study of the Essex Alliance League, a local amateur football league in England. Firstly, semi-structured interviews were held with multiple stakeholders to understand the ecosystem of grassroots football. From here, further semi-structured interviews were held with club sponsors to identify the conditions of CSR. This allowed the research to then issue a survey from which results were analysed and discussed using fuzzy set Qualitative Comparative Analysis (fsQCA). Findings: The ecosystem of grassroots football is formed by a myriad of stakeholders operating at a national level, all the way to more local governance structures within which the business-club relationship exists. Sponsors identified three main conditions of CSR: shared values, self-congruity, and happiness. However, following fsQCA, two pathways were found: (1) presence of shared values, and (2) presence of happiness with the absence of self-congruity. Practical implications: For practitioners, adaptations can be made for clubs to attract and maintain sponsorship as businesses seek to use grassroots sport as a channel for their own CSR objectives. To attract long term sponsorship, club managers are recommended to maintain long-term relationships with business owners especially in relation to personal values, fit, and happiness. As such, the responsibility of the club to ensure its stakeholders engage in promotional activity on behalf of their sponsor will help in maximising the financial value over multiple seasons. Originality/value: Where fertile ground for academic analysis in grassroots football is present, this research investigates CSR activity at this level of football, where most research is more concerned with professional levels of the game. Furthermore, this research reaches into the sport ecosystem through an understanding of co-created values between organisations in this exchange of shared values to meet common objectives
Analysis of Burr Formation in Low Speed Micro-milling of Titanium Alloy (Ti-6Al-4V)
The use of titanium based alloys in aerospace and biomedical applications
make them an attractive choice for research in micro-machining. In this
research, low speed micro-milling is used to analyze machinability of
Ti-6Al-4V alloy as low speed machining setup is not expensive and it can be
carried out on conventional machine tools already available at most
machining setups. Parameters like feed per tooth, cutting speed and depth of
cut are selected as machining variables and their effect on burr formation
is analyzed through statistical technique analysis of variance to determine
key process variables. Results show that feed per tooth is the most dominant
factor in burr formation (81 % contribution ratio). The effect of depth of
cut was found to be negligible. It was also observed that micro-milling at
optimum process parameters showed minimum burr formation. In terms of burr
formation, as compared to high speed machining setup, better results were
achieved at low speed machining setup by varying machining parameters.</p

Global burden of 288 causes of death and life expectancy decomposition in 204 countries and territories and 811 subnational locations, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021
BACKGROUND Regular, detailed reporting on population health by underlying cause of death is fundamental for public health decision making. Cause-specific estimates of mortality and the subsequent effects on life expectancy worldwide are valuable metrics to gauge progress in reducing mortality rates. These estimates are particularly important following large-scale mortality spikes, such as the COVID-19 pandemic. When systematically analysed, mortality rates and life expectancy allow comparisons of the consequences of causes of death globally and over time, providing a nuanced understanding of the effect of these causes on global populations. METHODS The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 cause-of-death analysis estimated mortality and years of life lost (YLLs) from 288 causes of death by age-sex-location-year in 204 countries and territories and 811 subnational locations for each year from 1990 until 2021. The analysis used 56 604 data sources, including data from vital registration and verbal autopsy as well as surveys, censuses, surveillance systems, and cancer registries, among others. As with previous GBD rounds, cause-specific death rates for most causes were estimated using the Cause of Death Ensemble model-a modelling tool developed for GBD to assess the out-of-sample predictive validity of different statistical models and covariate permutations and combine those results to produce cause-specific mortality estimates-with alternative strategies adapted to model causes with insufficient data, substantial changes in reporting over the study period, or unusual epidemiology. YLLs were computed as the product of the number of deaths for each cause-age-sex-location-year and the standard life expectancy at each age. As part of the modelling process, uncertainty intervals (UIs) were generated using the 2·5th and 97·5th percentiles from a 1000-draw distribution for each metric. We decomposed life expectancy by cause of death, location, and year to show cause-specific effects on life expectancy from 1990 to 2021. We also used the coefficient of variation and the fraction of population affected by 90% of deaths to highlight concentrations of mortality. Findings are reported in counts and age-standardised rates. Methodological improvements for cause-of-death estimates in GBD 2021 include the expansion of under-5-years age group to include four new age groups, enhanced methods to account for stochastic variation of sparse data, and the inclusion of COVID-19 and other pandemic-related mortality-which includes excess mortality associated with the pandemic, excluding COVID-19, lower respiratory infections, measles, malaria, and pertussis. For this analysis, 199 new country-years of vital registration cause-of-death data, 5 country-years of surveillance data, 21 country-years of verbal autopsy data, and 94 country-years of other data types were added to those used in previous GBD rounds. FINDINGS The leading causes of age-standardised deaths globally were the same in 2019 as they were in 1990; in descending order, these were, ischaemic heart disease, stroke, chronic obstructive pulmonary disease, and lower respiratory infections. In 2021, however, COVID-19 replaced stroke as the second-leading age-standardised cause of death, with 94·0 deaths (95% UI 89·2-100·0) per 100 000 population. The COVID-19 pandemic shifted the rankings of the leading five causes, lowering stroke to the third-leading and chronic obstructive pulmonary disease to the fourth-leading position. In 2021, the highest age-standardised death rates from COVID-19 occurred in sub-Saharan Africa (271·0 deaths [250·1-290·7] per 100 000 population) and Latin America and the Caribbean (195·4 deaths [182·1-211·4] per 100 000 population). The lowest age-standardised death rates from COVID-19 were in the high-income super-region (48·1 deaths [47·4-48·8] per 100 000 population) and southeast Asia, east Asia, and Oceania (23·2 deaths [16·3-37·2] per 100 000 population). Globally, life expectancy steadily improved between 1990 and 2019 for 18 of the 22 investigated causes. Decomposition of global and regional life expectancy showed the positive effect that reductions in deaths from enteric infections, lower respiratory infections, stroke, and neonatal deaths, among others have contributed to improved survival over the study period. However, a net reduction of 1·6 years occurred in global life expectancy between 2019 and 2021, primarily due to increased death rates from COVID-19 and other pandemic-related mortality. Life expectancy was highly variable between super-regions over the study period, with southeast Asia, east Asia, and Oceania gaining 8·3 years (6·7-9·9) overall, while having the smallest reduction in life expectancy due to COVID-19 (0·4 years). The largest reduction in life expectancy due to COVID-19 occurred in Latin America and the Caribbean (3·6 years). Additionally, 53 of the 288 causes of death were highly concentrated in locations with less than 50% of the global population as of 2021, and these causes of death became progressively more concentrated since 1990, when only 44 causes showed this pattern. The concentration phenomenon is discussed heuristically with respect to enteric and lower respiratory infections, malaria, HIV/AIDS, neonatal disorders, tuberculosis, and measles. INTERPRETATION Long-standing gains in life expectancy and reductions in many of the leading causes of death have been disrupted by the COVID-19 pandemic, the adverse effects of which were spread unevenly among populations. Despite the pandemic, there has been continued progress in combatting several notable causes of death, leading to improved global life expectancy over the study period. Each of the seven GBD super-regions showed an overall improvement from 1990 and 2021, obscuring the negative effect in the years of the pandemic. Additionally, our findings regarding regional variation in causes of death driving increases in life expectancy hold clear policy utility. Analyses of shifting mortality trends reveal that several causes, once widespread globally, are now increasingly concentrated geographically. These changes in mortality concentration, alongside further investigation of changing risks, interventions, and relevant policy, present an important opportunity to deepen our understanding of mortality-reduction strategies. Examining patterns in mortality concentration might reveal areas where successful public health interventions have been implemented. Translating these successes to locations where certain causes of death remain entrenched can inform policies that work to improve life expectancy for people everywhere.

Heat transfer intensification of nanomaterial with involve of swirl flow device concerning entropy generation
Abstract The thermal features of hybrid nano-powder turbulent motion through a pipe employing helical turbulator is numerically simulated via Finite Volume Method (FVM). The hybrid nanofluid (MWCNTs + Fe3O4 + H2O) is obtained by uniformly dispersing MWCNTs + Fe3O4 nanomaterials in H2O. The characteristics features of thermal energy transfer of hybrid nanofluid are investigated by varying the pitch ratio (P) of the helical turbulator and Reynolds number (Re) of the fluid. The outputs of the study are depicted in terms of contour plots of temperature, velocity, frictional irreversibility Sgen,f, and thermal irreversibility Sgen,th. The variation of Sgen,f, and Sgen,th with changing P and Re are also displayed by 3D plots. It is found that making the fluid more turbulent by increasing Re, the temperature of the fluid drops whereas the fluid velocity augments. The frictional irreversibility enhances, whereas the thermal irreversibility drops with the increasing turbulent motion. The decreasing P causes to drop the temperature of the higher turbulent fluid flow, while opposite effect is observed for smaller Re. The decreasing P causes to enhance the fluid mixing and thus augments the fluid velocity. Sgen,f and Sgen,th both augment with decreasing P. The comparison of current outputs with the older article shows an acceptable accuracy. The results of the present investigation will be useful in modelling of efficient thermal energy transfer systems
The mechanism behind employee agreeableness and group performance ratings: a Pakistani study
Purpose
This study seeks to examine the links between employee agreeableness, group performance, and peers' perceptions of threat of retaliation, through relationship conflict.
Design/methodology/approach
In a laboratory setting, 42 groups of undergraduate students (N = 182) from a Pakistani university were assigned to group projects to be completed within four months. Data collected from three different questionnaires at four different times and actual scores awarded by the course instructor to each group were used for the analyses. Based on rWG(J) and ICC(1), level 1 (182 students') data were aggregated to level 2 (groups), and then analysed using regression analysis followed by Preacher and Hayes' bootstrapping procedure.
Findings
Results suggest that high agreeableness predicts group performance positively and peers' perceptions of threat of retaliation negatively. Moreover, relationship conflict among group members significantly mediates the agreeableness-group performance relationship. The above relationships may be sensitive to national culture.
Research limitations/implications
In this study, groups were formed for a few months, whereas in real organizational life, workgroups are formed for different durations. Therefore, the range of situations to which these findings generalize remains an open question.
Practical implications
Agreeableness of group members can be constructive for performance of the group. Managers may utilize this insight while forming groups, and rating performance.
Originality/value
There is dearth of research illuminating how employee's personality traits affect group performance and appraisal ratings. The study tests the effects of employee agreeableness on: (1) group performance, as rated by supervisors; (2) the threat of retaliation, as perceived by peer raters; and (3) the mediating effect of relationship conflict
