It is hoped that through this study, various stakeholders such as school, district ed-ucation offices as well as the Ministry of Education will be able to assist in planning and organizing efforts to address the role of teacher leadership to produce highly talented future leaders at schools.

The objective of this study is to describe the influence of principals' leadership, work environment, and affiliation motivation on improving the performance of certified teachers at Private Vocational Schools in Tegal City, Indonesia. To achieve this objective, the current study carried out a research survey in Private Vocational Schools of Tegal City. Therefore, data collection was achieved by using survey questionnaire and respondents of the study was school teachers. Thus, this study used quantitative research approach with cross-sectional research design. Data were analyzed by using latest technique, namely; Structural Equation Modeling (SEM) based on Partial Least Square (PLS). The results of the study showed that the leadership of the principal, the work environment, and the motivation to affiliate were well per-ceived by the teachers. Both principal leadership and work environment had direct effects on improving the certified teacher’s performance. The teacher’s performance can be explained by independent head leadership and work environment variables, however, for independent variables namely; motivation to affiliate did not have enough significant influence. Hence, teacher’s performance can be improved through the leadership of principals and a conducive work environment.

This paper explored the dynamics of monetary policy and its effect on private investment, using annual frequency data from 1981 to 2017. The paper employed autoregressive distributive lags methodology to estimate the link between private investment and some selected monetary indicators. Empirical finding shows that broad money supply increases private investment in the long run for the study area. Interestingly, our study shows inverse relationship between exchange rate and private investment. These findings are insightful for policymakers for strategic policy mix construction. Consequently, the study recommends, among other things, proper coordination of monetary and fiscal policies, good macroeconomic policies, proper channeling of financial resources to the private sector and proper measures for controlling inflation.

Good management of cash flow will help managers control cost estimates, control plan implementation as well as control additional costs, ensuring project success. Therefore, identify-ing the factors influencing the cash flow of enterprises helps create synchronous solutions to improve the efficiency of cash flow management, contributing for improving the operational efficiency of the enterprises. This study is based on a survey to determine the factors influenc-ing the cash flow through the questionnaires and interviews of 105 construction companies listed on the Vietnam Stock Exchange in 2018. The study conducts descriptive statistics anal-ysis of surveyed enterprises; check the Exploratory Factor Analysis (EFA) analysis conditions to determine the groups of influencing factors on cash flow in construction companies listed on the Vietnam Stock Exchange. At the same time, this study remains to check a sample T-test with a value set to 3.0 and 5% reliability and analysis of EFA discovery factors to select components with the highest coefficients and load components. Based on the EFA analysis results, the study finds six main groups of factors affecting the cash flow of construction companies. They are: macro environment; construction period; payables and receivables; construction cost; retention; loan payment and tax. The study also shows that the effect of varia-bles to cash flow management varied with a mean value from 0.17 to 0.518. Based on the research results, the authors provide some recommendations to strengthen cash flow management in construction companies listed on the Vietnam Stock Exchange.

Epithelial sodium channels (ENaC) is a protein that plays a role in maintaining sodium levels and can be used as a biomarker of hypertension. This study aims to develop an electrochemical immunosensor for detecting ENaC using a screen-printed carbon electrode (SPCE) which is modified with reduced graphene oxide (RGO). The performance of RGO enhanced to provide covalent bonds between the -COOH residues at RGO and the terminal -NH2 of anti-ENaC. While anti-ENaC and ENaC decrease the peak of ferric cyanides current because of the resistance effect. The optimum concentration of anti-ENaC was 1.0 µg/mL for 30 min incubation time. The various concentration of ENaC has a linear relationship with the decreasing of ferric cyanide peak current in the range of 0.01-1.5 ng/mL, and the limit of detection found at 0.198 ng/mL. The low-level exposure of ENaC warrants the realization of a point-of-care device for early detection of hypertension in urine samples.

In order to investigate the isomerization and conversion mechanism of the advantageous and widely used nonsteroidal anti-inflammatory medicine flurbiprofen, the hybrid density functional theory was applied. According to the results, the rearrangement reaction of (R)-flurbiprofen to its (S)-enantiomer happens in a [1,3]-hydrogen shifts with inversion of configuration at chiral center C14. From the calculated energies, it can be understood that the rate-limiting step in the flurbiprofen isomerization is the excitation of (R)-flurbiprofen methyl ester in its initial form to the first excited singlet state S1 at λ=243.91 nm. we studied this process by scanning the C14-H17 distance for the excited singlet to get more information about the process of isomerization occurring upon excitation. The results of calculations demonstrated that the isomerization process should pass through a ~71 kcal/mol barrier. The (S)-flurbiprofen methyl ester is more photostable than its related (R)-enantiomer. This issue can be attributed to the -1.50 kcal/mol of thermodynamic stability of the (S)-flurbiprofen methyl ester.

Contamination of soils by trace elements is a worldwide concern and has negative effects on environmental sustainability. Geochemical assessment of soils using appropriate indicators and pollution indices has received much attention in recent years in efforts to rehabilitate this resource. This study quantified pollution of soils by trace elements at the Roundhill landfill, South Africa using indices and multivariate statistics. Soils were collected and assayed for trace metals using x-ray fluorescence. Pollution indices classified soil contamination levels while multivariate statistical analysis was conducted using principal component and cluster analyses. Findings showed that concentrations of all elements decreased with increasing distance from the landfill. Low to extremely high pollution was evident in all soils and Cr had the highest values compared to other elements. Negative correlation and weak clustering of Cr and Cd was associated with different wastes disposed at the landfill. Reported pollution in soils was associated with the influence of landfill leachate in the investigated area.

A series of fourteen chalcone was synthesized via. Claisen–Schmidt condensation between substituted 2- hydroxyl acetonaphthones and substituted benzaldehyde in presence of tripotassium phosphate (K3PO4) catalyst. The reaction was carried out by conventional method using 2-methoxyethanol. The procedure is simple and efficient in terms of reaction time, easy workup and isolation of products and yields. In-vitro all these synthesized compounds were screened and evaluated for the cytotoxic and antimicrobial activity. It was found that these compounds had significant cytotoxic activity in comparison with standard 5-flurouracil. The compounds 3a, 3b, 3h, 3f and 3l were screened by MTT assay against liver cancer cell line-HepG2. Among these, the compound 3b and 3c showed LC50 values of 997.14 μM/ml and 284.13 μM/ml., respectively. The remaining compounds did not display the LC50 values. The compound 3l displayed the strongest cytotoxic activities with IC50 value of 91.85 μg/ml against liver cancer cell line. The Chalcone 3a, 3f, 3h and 3e demonstrated excellent antimicrobial activity and the remaining were moderately active against tested pathogens. The antimicrobial effects of all the tested compounds are due to the presence of pharmacological active substituent in the basic nucleus of Chalcones. Therefore, the present study leads to the development of new class of anticancer and antimicrobial inhibitory candidates.
