Single-lap joints of similar and dissimilar adherends bonded with a polyurethane adhesive used in the automotive industry

The mechanical performances of single-lap joints between similar and dissimilar adherends bonded with a bi-component polyurethane adhesive have been studied in the present work. The substrate materials include both carbon fibre reinforced composite material (CRFP) and painted metal substrates (PMS). The following substrate combinations were tested: CFRP/CFRP, PMS/PMS, and CFRP/PMS. Two adhesive overlaps, 12 mm and 24 mm, with a fixed thickness were studied to assess the mechanical behaviour of the adhesive joints. The experimental results have been used to construct a finite element model of the single lap joint tests. The objective is to determine the material cohesive properties, in particular the maximum shear stress and the corresponding energy release rate, of the adhesive layer for each retained combination of substrates. An optimization scheme based on transient nonlinear finite element analysis has been here considered, where cohesive parameters of the adhesive layer are handled as design variables. Material parameters are firstly identified for the 12 mm overlap, minimizing the discrepancy between the experimental and numerical force-displacement curves. Then, to validate the obtained properties, results of the 24 mm overlap single lap joint tests are used. The comparison between the experimental and numerical results shows a very good agreement.
How transformational leadership influences innovative behavior: the mediating role of psychological empowerment and proactivity of employees

This research aims to examine the impact of transformational leadership on innovative behavior of employees within the organization. It draws on conservation of resources theory and examines when and how transformational leadership style relates to innovative behavior of employees. The study proposes a sequential mediation effect of psychological empowerment and proactivity of employees that predicts innovative behavior among employees. The data of 230 employees is collected from large public sector organizations, from employees and their managers by utilizing three-wave time lagged study design. The results of the study were obtained using PROCESS macro by Hayes via 2000 resample bias corrected (BC) bootstrap method. The findings not only validate the applicability of psychological empowerment and proactivity for innovative behavior but also found these as mediators between transformational leadership and innovative behavior relationship. Theoretical and practical implications are also discussed in light of the findings.
Effect of dietary energy density and folic acid supplementation on white striping occurrence and growth performance of broiler chickens

Abstract: Broilers were allocated to eight treatments consisting of two energy levels: normal (NE) and high (HE), and four folic acid (FA) levels (2.2, 5, 10, and 15 ppm). On day 42, two male and two female chickens were euthanized per pen, and white striping (WS) evaluation was performed on the pectoralis major. Birds fed HE diets had reduced (P < 0.05) feed intake and feed conversion rate than those on NE diets. With increasing FA levels, there was reduced (P < 0.05) WS score and increased (P < 0.05) normal breast fillet percentage in female chickens but not in the males. WS scores were higher (P < 0.01) in male chickens than in the females.

Soil organic carbon changes after seven years of conservation agriculture in a rice–wheat system of the eastern Indo‐Gangetic Plains

Sequestration of soil organic carbon (SOC) is an important strategy to improve soil quality and to mitigate climate change. To investigate changes in SOC under conservation agriculture (CA), we measured SOC concentrations after seven years of rice (Oryza sativa L.)–wheat (Triticum aestivum L.) rotations in the eastern Indo‐Gangetic Plains (IGP) of India under various combinations of tillage and crop establishment methods. The six treatments were as follows: conventional till transplanted rice followed by conventional till wheat (CTR‐CTW), CTR followed by zero‐till wheat (CTR‐ZTW), ZT direct‐seeded rice followed by CTW (ZTDSR‐CTW), ZTDSR followed by ZT wheat both on permanent raised beds with residue (PBDSR‐PBW+R), and ZTDSR followed by ZTW both with (ZTDSR‐ZTW+R) and without residues (ZTDSR‐ZTW). We hypothesized that CA systems (i.e. ZT with residue retention) would sequester more carbon (C) than CT. After seven years, ZTDSR‐ZTW+R and PBDSR‐PBW+R increased SOC at 0–0.6 m depth by 4.7 and 3.0 t C/ha, respectively, whereas the CTR‐CTW system resulted in a decrease in SOC of 0.9 t C/ha. Over the same soil depth, ZT without residue retention (ZTDSR‐ZTW) only increased SOC by 1.1 t C/ha. There was no increase in SOC where ZT in either rice or wheat was followed by CT in the next crop (i.e. CTR‐ZTW and ZTDSR‐CTW), most likely because the benefit of ZT is lost when followed by tillage. Tillage and crop establishment methods had no significant effect on the SOC stock below the 0.15‐m soil layer. Over the seven years, the total carbon input from above‐ground residues was ca. 14.5 t/ha in ZTDSR‐ZTW+R and PBDSR‐PBW+R, almost sixfold greater than in the other systems. Our findings suggest that the increased biomass production achieved through a combination of ZT and partial residue retention offers an opportunity to increase SOC whilst allowing residues to be used for other purposes.
Improved model exploration for the relationship between moral foundations and moral judgment development using Bayesian Model Averaging

ABSTRACT Although some previous studies have investigated the relationship between moral foundations and moral judgment development, the methods used have not been able to fully explore the relationship. In the present study, we used Bayesian Model Averaging (BMA) in order to address the limitations in traditional regression methods that have been used previously. Results showed consistency with previous findings that binding foundations are negatively correlated with post-conventional moral reasoning and positively correlated with maintaining norms and personal interest schemas. In addition to previous studies, our results showed a positive correlation for individualizing foundations and post-conventional moral reasoning. Implications are discussed as well as a detailed explanation of the novel BMA method in order to allow others in the field of moral education to be able to use it in their own studies.
Nestling diet and parental food provisioning in a declining mountain passerine reveal high sensitivity to climate change

Mountain ecosystems naturally experience strong seasonal weather variations leading to a brief peak in food availability that constrains bird reproduction. Climate change accentuates both the intra- and interannual weather variability, which in turn can reduce the predictability of food resources and hence impact population demography. Yet, relatively little is known about the influence of environmental factors on the breeding ecology of mountain birds. Here, we quantified the nestling diet and provisioning behaviour of the Alpine Ring Ouzel (Turdus torquatus alpestris), an emblematic and declining thrush species typical of central European treeline ecotones, and relate these parameters to local weather conditions. Nests were monitored with camcorders to assess prey provisioning frequency and identify items delivered by parents to nestlings, as well as to estimate prey biomass. Our results indicate the prominence of earthworms (Lumbricidae) in the nestling diet, both in terms of abundance (80%) and biomass (90%). Elevated ambient temperatures negatively impacted both prey provisioning rates and biomass delivered to chicks by parents, while rainfall had a positive effect on the delivered biomass. The mean prey item biomass decreased throughout the breeding season, as did the proportion of earthworms in nestlings’ diet. These findings highlight the key role played by local weather in parental provisioning behaviour, probably reflecting the low availability of the staple food source, earthworms, in warm and dry weather contexts. In particular, they underpin how climate alterations, notably increasing ambient temperatures and changing precipitation regimes, could impact mountain birds. Although effects on reproductive performance and population dynamics still ought to be studied, these results further our understanding of the ecological mechanisms potentially at play in the decline of wildlife inhabiting high-elevation, climate-sensitive ecosystems.
Computational Nonimaging Geometric Optics: Monge-Ampère

1. Overview The goal of computational nonimaging geometric optics is the efficient design of optical lenses and mirrors for the accurate control of light. Light waste in the United States is equivalent to 72.9 million mwh of unnecessary electricity generated at a cost of $6.9 billion a year [10] and the amount of CO2 generated in that process is equivalent to 9.5 million cars on the roads. Light pollution also has adverse health impacts on wildlife and humans. Other examples where an accurate control of light is required include projection displays, laser weapons, concentrated solar energy, and medical illuminators. Freeform illumination design, i.e., with no a priori symmetry assumption, often leads to numerically solving a nonlinear second order
Na Storage Capability Investigation of a Carbon Nanotube-Encapsulated Fe1-xS Composite

A promising anode material consisting of Fe1–xS nanoparticles and bamboo-like carbon nanotubes (CNTs) has been designed and prepared by an effective in situ chemical transformation. The resultant Fe1–xS@CNTs with a three-dimensional network not only provide high conductivity paths and channels for electrons and ions but also offer the combined merits of iron sulfide and CNTs in electrochemical energy storage applications, leading to outstanding performance as an anode material for sodium-ion batteries. When tested in a half-cell, a high capacity of 449.2 mAh g–1 can be retained after 200 cycles at 500 mA g–1, corresponding to a high retention of 97.4%. Even at 8000 mA g–1, a satisfactory capacity of 326.3 mAh g–1 can be delivered. When tested in the full cell, a capacity of 438.5 mAh g–1 with capacity retention of 85.0% is manifested after 80 cycles based on the mass of the anode. The appealing structure and electrochemical performance of this material demonstrate its great promise for applications in pra.

The Determinants Factors of Womenpreneurship Performances in Low Economic Class : An Evidence from Melaka

Within this study, we want to examine factors those determine to the rise of womenpreneurship, since it is one of the most important 2030 Agenda for Sustainable Development to eradicate national poverty as well as to support the innovation and ever-growing economy. The increasing of women's participation in entrepreneurs demonstrated positive impact of female entrepreneurs, not only on the family but also on economic growth and development. We build our theoretical framework based on literature surveys; that factors of an inspiring role model, education on digital skills, and financial support, which taken from Theory of Planned Behaviour (TPB), contribute to this increasing of womenpreneurship participation. As far as we have known, we are among the first who establish the study focused on women entrepreneurs, especially among the B40 economic social class. We employ a quantitative approach of Multiple Regression Linear Analysis with a convenience sample, comprising 100 women entrepreneurs in Melaka. We find that women entrepreneurs with clear targets, would not only possess the right attitude in their entrepreneurial path, but also become the society role models at the same time. Also, when facing the social pressure, womenpreneurs will equip themselves with proper education to grasp more opportunities. Even though limited by the participation rate, especially those in the rural areas, we would like to make recommendations on ways to encourage more women to pursue entrepreneurship, especially during the Covid-19 outbreak.
Optical and structural studies on bio-synthesized ZnO using Citrullus lanatus peel extract

Bio-fabrication of ZnO films using plants, enzymes, and microorganisms has been recognized as an environmentally friendly procedure as an alternative to physical and chemical methods. In this research, the optical and structural properties of ZnO thin film have been investigated using UV-Vis spectrophotometer, X-ray diffraction (XRD), and Scanning Electron Microscopy (SEM), respectively. The ZnO films was prepared by spin-coating the mixed solution of Zn(NO3)2 and watermelon (Citrullus lanatus) peel extract on glass substrate. The ZnO films were then annealed at 400°C for 3h. The UV-Vis absorbance spectra show the strong absorption peaks occurs over a range of wavelengths of 220-380nm, and 190-235 nm for pre-annealed and annealed samples, respectively. The optical band gap of the samples was influenced by the heat treatment. The as-prepared samples synthesized at pH 8 is 3.73 eV and increased up to 5.4 eV after annealed at 400 °C for 3 h. This result suggested that pre-annealed sample has better photocatalytic activity compared to the annealed samples. The XRD pattern of the ZnO films exhibits the ZnO diffraction peaks that correspond to the hkl of hexagonal wurtzite structure. SEM image shows that the morphology of ZnO samples are spherical and rod-like microstructure.
Anti-Tumor and Anti-Invasive Effects of ONC201 on Ovarian Cancer Cells and a Transgenic Mouse Model of Serous Ovarian Cancer

ONC201 is a promising first-in-class small molecule that has been reported to have anti-neoplastic activity in various types of cancer through activation of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) as well as activation of mitochondrial caseinolytic protease P (ClpP). The present study was to explore the anti-tumor potential effect of ONC201 in ovarian cancer cell lines and in a transgenic mouse model of high grade serous ovarian cancer under obese (high fat diet) and lean (low fat diet) conditions. ONC201 significantly suppressed cell proliferation, induced arrest in G1 phase, and increased cellular stress and apoptosis, accompanied by dual inhibition of the AKT/mTOR/S6 and MAPK pathways in OC cells. ONC201 also resulted in inhibition of adhesion and invasion via epithelial–mesenchymal transition and reduction of VEGF expression. Pre-treatment with the anti-oxidant, N-acetylcysteine (NAC), reversed the ONC201-induced oxidative stress response, and prevented ONC201-reduced VEGF and cell invasion by regulating epithelial–mesenchymal transition protein expression. Knockdown of ClpP in ovarian cancer cells reduced ONC201 mediated the anti-tumor activity and cellular stress. Diet-induced obesity accelerated ovarian tumor growth in the KpB mouse model. ONC201 significantly suppressed tumor growth, and decreased serum VEGF production in obese and lean mice, leading to a decrease in tumoral expression of Ki-67, VEGF and phosphorylation of p42/44 and S6 and an increase in ClpP and DRD5, as assessed by immunohistochemistry. These results suggest that ONC201 may be a promising therapeutic agent to be explored in future clinical trials in high-grade serous ovarian cancer.
Measurements of Physiochemical Parameters and Trace Element Concentration of Rock Samples in Ogun State

Trace elements occur in tiny quantities but detectatble, in minerals and rocks. They are always less than 1% of the all the minerals. When trace elements’ concentration is low, they become beneficial and aids growth an metabolism but when present at high concentrations begin to pose health risks. This paper aimed at investigating and analyzing the pH, electrical conductivity, and trace element concentrations in the rocks samples collected from twenty local government headquarters of Ogun state, using a pH meter, an atomic absorption spectrometer and an electrical conductivity meter, respectively. The measured pH ranged between 6.63 to7.34, which suggests that the rocks in these areas are neutral. The electrical conductivity estimated varied between 46.3 and 598µScm−1, with Ewekoro having the highest conductivity, which may be due to the accumulation of limestone in this area. It was noticed that all the elements were present in minute quantities except iron (Fe), which was present in high concentration that exceeded the recommended value. It was thenconcluded that the rocks in the study area are neutral and contain a high concentration of iron.
Self-Determined Motivation Mediates the Association between Self-Reported Availability of Green Spaces for Exercising and Physical Activity: An Explorative Study

The aim of the study was to test the associations between the self-reported access to exercise in green spaces (GS) and moderate-to-vigorous physical activity (MVPA) testing the mediating role of the motivation. Based on self-determination theory (SDT), we expected that self-determined motivation will mediate the associations between the self-reported availability of GS for exercising (GSE) and MVPA with the most self-determined exercise regulation forms (identified and intrinsic motivation) demonstrating the strongest positive associations between the variables. Method: The sample consisted of 2154 participants (74.7% women). The ages ranged from 18 to 79 years, with a mean age of 32.6 (SD = 12.2) years. Participants completed the Behavior Regulation in Exercise Questionnaire-2, the measures of self-reported distance to residential GS (RGS), availability of the GS for exercising (GSE), and physical activity (PA). Logistic regression and path analysis were used to test the associations between study variables. Results: Higher reported distance to RGS was associated with lower reported availability of GSE, but not PA. Availability of GSE was directly associated with more frequent MVPA. More autonomous forms of exercise behavior regulation (intrinsic and identified regulations) mediated the associations between self-reported availability of GSE and MVPA. Internal and identified exercise regulations were directly associated with more frequent MVPA. Conclusions: The results of the present study support the main tenets of SDT suggesting that self-determined behavioral exercise regulation is an important mediator between the self-reported availability of GSE and general MVPA. Practical implications of these findings are discussed herein.
Use of Estradiol Cypionate to induce ovulation in buffalo raised in floodplain areas of Itacoatiara, Amazonas

ABSTRACT This study aimed to determine the efficiency of estradiol cypionate (EC) as an ovulation inducer in a Timed Artificial Insemination protocol. 69 buffalo cows received an intravaginal progesterone device and 2mg of estradiol benzoate (EB) at D0. On D9, the intravaginal device was removed and 0.53mg of prostaglandin (PGF2α) and 400UI of equine chorionic gonadotrophin (eCG) were applied. The cows were distributed into two groups: the first group received 1mg of EC (ECG) in D9, and the second group received 1mg of EB (EBG) in D10. Inseminations occurred on D11. Ovarian activity and pregnancy diagnosis were analyzed by ultrasonography. There was no difference (P>0.05) in follicular diameter (9.6 ± 0.89mm vs. 10.7 ± 1.12mm; P=0.06), in ovulation rate (90.9% vs. 90.9%; P=1) and pregnancy rate (58.8% vs. 62.9%; P=0.79), however, buffalo cows from the ECG treatment have less time between P4 removal and ovulation when compared to EBG buffalos (37.4h vs. 52.8h; P=0.001), respectively. Thus, it was concluded that the implantation of TAI in the floodplain of Amazonas is feasible and the use of EC results in successful rates, similar to EB.
The Effect of Financial Compensation and Work Pressure on Employees’ Performance through Job Satisfaction

This study aims to examine and analyze the effect of financial compensation and work pressure on the performance of employees through job satisfaction in DGT Regional office of South, West and South-East Sulawesi. Data was collected by a survey method, using questionnaire instruments created by Google Form platform and distributed to all civil servants of DGT Regional office of South, West and South-East Sulawesi and are grouped into five clusters. Of the 1,701 employee population, there were 352 employees who responded. Data is then analyzed using the Structural Equation Model (SEM) with the help of the SPSS AMOS application. The results showed that financial compensation and work pressure have a significant positive effect on job satisfaction. Interestingly, both variables, financial compensation and work pressure, did not show a significant effect on employees’ performance. Job satisfaction has a significant positive effect on employees’ performance.
Option-Implied Dependence and Correlation Risk Premium

We propose a novel model-free approach to obtain the joint risk-neutral distribution among several assets that is consistent with options on these assets and their weighted index. We implement this approach for the nine industry sectors comprising the S&P 500 index and find that their option-implied dependence is highly asymmetric and time-varying. We then study two conditional correlations: when the market moves down or up. The risk premium is strongly negative for the down correlation but positive for the up correlation. Intuitively, investors dislike the loss of diversification when markets fall, but they actually prefer high correlation when markets rally.
