The base cut of cultures is one of the most studied parameters, and the variables involved in this process should be better evaluated under controlled conditions. The aim of this study was to evaluate, using an electromechanical device, under controlled conditions, the influence of the cutting angle and the machine's translation speed on the impact force generated on sugarcane stalks in mechanized harvesting. The study was carried out at the Nempa - Center for Testing of Agroforestry Machines and Tires (NEMPA) at UNESP/Botucatu. For the tests, the Sugarcane Basal Cut Testing Device (BCTD) was used. The collected data were evaluated using multiple linear regression analysis, using the stepwise method. The results showed that the angulation of the cutting blades is the most significant variable in relation to the impact force generated in the cutting process of sugarcane stalks, this research also managed to assess that the intensity of the angulation effect is more than 2 times greater than the effect generated by the displacement speed in the mechanized harvesting process.

This study was undertaken to determine the impact of sarcomere length (SL) on the level of cooperative activation of the cardiac myofilament at physiological [Mg2+]. Active force development was measured in skinned rat cardiac trabeculae as a function of free [Ca2+] at five SLs (1.85–2.25 μm; 1 mM free [Mg2+]; 15°C). Only muscle preparations with minimal force rundown during the entire protocol were included in the analysis (average 7.2 ± 1.7%). Median SL was measured by on-line computer video micrometry and controlled within 0.01 μm. Care was taken to ensure a sufficient number of data points in the steep portion of the [Ca2+]-force relationship at every SL to allow for accurate fit of the data to a modified Hill equation. Multiple linear regression analysis of the fit parameters revealed that both maximum, Ca2+-saturated force and Ca2+sensitivity were a significant function of SL ( P < 0.001), whereas the level of cooperativity did not depend on SL ( P = 0.2). Further analysis of the [Ca2+]-force relationships revealed a marked asymmetry that, also, was not affected by SL ( P = 0.2–0.6). Finally, we found that the level of cooperativity in isolated skinned myocardium was comparable to that reported for intact, nonskinned myocardium. Our results suggest that an increase in SL induces an increase in the Ca2+ responsiveness of the cardiac sarcomere without affecting the level of cooperativity.

The objective of the study was to evaluate the impact of stores existence toward sales turnover of stalls in Mataram city. Associative research design was adopted as the study guide. Purposive sampling techniques were used in which 100 copies of the research instrument were administered to stalls owner in Mataram city, out of which 100 copies of questionnaire were filled and returned. Test of validity and reliability, classical assumption test, and multiple linear regression analysis was used to analyse the data generated from respondents. The findings revealed that stores existence variable consisted of services, product diversification, price, and comfortable of consumer have significant influence on sales turnover of stalls at 0,05 level (2-tailed). The result of the research shows the variables negatively affecting sales turnover of stalls. Furthermore, price ranks the first follow by comfortable, product diversification, and services. This research will help the owner of stalls to understand and recognize the ranking of variables affecting sales turnover of stalls in Mataram city. Keywords:   Stores Existence, Stall, and Sales Turnover.

<pre>The objective of this study is empirically identify the impacts of Good Corporate Governance and capital structure on firm value with financial performance as intervening variable. We operate quantitative approach within the scope of manufacturing company of metal, chemical, and plastic packaging sector which listed in Indonesia Stock Exchange during the 2017-2018 periods as the population. Samples are chosen by purposive sampling method inwhich the company must report the financial statement in a row, obtained 79 observations. The data analysis technique used is financial ratio analysis to determine the condition of the business financial ratios of the variables studied. Data were analyzed using multiple linear regression analysis. The result shows that corporate governance and capital structure influence the firm value, moreover the use of institutional ownership ratio and capital structure will increase the value of the firm. The result also shows that the impact of Corporate governance and capital structure on the company value are mediated by financial performance. It means that the value of the firm can increase if the company able became an effective monitoring tool.</pre>

The purpose of this study was to determine the impact of employee relations (variable X1) and Work Discipline (variable X2) on Employee Performance (variable Y). The method used in this research is to use descriptive and associative methods. Data collection techniques used by researchers in this study are through observation, questionnaire interviews, documentation and literature studies. The data analysis technique used is the validity test, reliability test, multiple linear regression analysis, including the test of the coefficient of determination and multiple correlation coefficients. The results of the test of the coefficient of determination seen from the value (Adjusted R2) of 0.531 can be interpreted that the impact of employee relations and working discipline on employee performance is equal to 53.1%. The remaining 46.9% is influenced by other factors outside this study. Conclusion, there is a moderate relationship between employee relations and work discipline with employee performance.

The purpose of the chapter is to study what effect CSR has on firms' overall performance in a developing country context. While most of the previous empirical researches focused on the relationship between CSR and financial performance, the present study suggests exploring the impact of CSR on overall performance which encompasses economic, environmental, and social dimensions as well as stakeholders. The empirical study aims to analyze and measure the social and environmental involvement of large Moroccan firms operating in the main sectors of activity and located in different geographical areas. Using multiple linear regression analysis, the authors empirically test the impact of CSR on overall performance on a sample of 44 companies. The main findings reveal that CSR is a driver for improving image and reputation, enabling the firm to achieve overall corporate performance. On the basis of the main results, they set out some managerial implications and further directions for CSR research in developing countries.

ABSTRACT Voriconazole (VCZ) is an antifungal agent with wide inter- and intrapatient pharmacokinetic (PK) variability and narrow therapeutic index. Although obesity was associated with higher VCZ trough concentrations in adults, the impact of obesity had yet to be studied in children. We characterized the PK of VCZ in obese patients by accounting for age and CYP2C19 phenotype. We conducted intensive PK studies of VCZ and VCZ N-oxide metabolite in 44 hematopoietic stem cell transplantation (HSCT) recipients aged 2 to 21 years who received prophylactic intravenous VCZ every 12 hours (q12h). Blood samples were collected at 5 and 30 minutes; at 1, 3, 6, and 9 hours after infusion completion; and immediately before the next infusion start. We estimated PK parameters with noncompartmental analysis and evaluated for an association with obesity by multiple linear regression analysis. The 44 participants included 9 (20%) with obesity. CYP2C19 metabolism phenotypes were identified as normal in 22 (50%), poor/intermediate in 13 (30%), and rapid/ultrarapid in 9 patients (21%). Obesity status significantly affects the VCZ minimum concentration of drug in serum (Cmin) (higher by 1.4 mg/liter; 95% confidence interval [CI], 0.0 to 2.8; P = 0.047) and VCZ metabolism ratio (VCZRATIO) (higher by 0.4; 95% CI, 0.0 to 0.7; P = 0.03), while no association was observed with VCZ area under the curve (AUC) (P = 0.09) after adjusting for clinical factors. A younger age and a CYP2C19 phenotype were associated with lower VCZ AUC. Obesity was associated with decreased metabolism of VCZ to its inactive N-oxide metabolite and, concurrently, increased VCZ Cmin, which is deemed clinically meaningful. Future research should aim to further characterize its effects and determine a proper dosing regimen for the obese.
