60 samples were collected, 40 samples were for patients with CO-19 and 20 samples were for healthy control people. Tests were performed to know the patients people through the ADVIA Chemistry XPT System and an analysis was performed to find out the ratio of ferritin to patients based on I CHORMA. As for the LDH analysis, use the Cedex Bio Analyzer to find results were found that showed the great effect on ferritin and LDH, where the ratio of standard deviation to LDH to patients people was 441.5641 ±  234.80 and for control 185.08 ±  35.26 as for the analysis of ferritin, where the ratio of standard deviation was 853.92 ±  516.13 to patients people and for control 88.48 ±  59.44 And through the work of statistical analysis to know the effect of the CO-19 on the abnormal ratio, as the statistical analysis proved that there is a positive effect on ferritin and LDH to patients  people and the control has a negative effect, and this explains the reason for the lack of the amount of iron present in the body is little if the person is a carrier of the disease

Aims: To analyze the level of health of sharia general banks in Indonesia and their effects on profitability. Study Design: The research method used is quantitative descriptive research. Place and Duration of Study: The sampling technique used was purposive sampling. The study was conducted a Sharia General Bank registered in the Indonesian Financial Services Authority with a research period of 2015-2018. Methodology: The analytical method used is the inferential statistical analysis test using SmartPLS Professional 3.0 analysis tools, namely with a descriptive test, and inferential statistical analysis. Results: Sharia Commercial Banks in the 2015-2018 period based on Non-Performing Finance (NPF) have a healthy predicate and have a negative significant effect on profitability. Based on the Fair to Healthy Ratio (FDR) predicate as Healthy, and no significant positive effect on profitability. Based on Good Corporate Governance (GCG) with a healthy predicate, and no significant positive effect on profitability. Based on Operating Efficiency Ratio (OER) with a healthy predicate, and a significant negative effect on profitability. Based on the Capital Adequacy Ratio (CAR) which is categorized as Very Healthy, and no significant positive effect on profitability. Conclusion: Generally, Islamic commercial banks are in good health. However, the achievement of this soundness level is carried out by always striving to comply with the provisions given by Bank Indonesia, not optimizing the available resources so that the bank remains in a healthy condition while meeting the criteria of Bank Indonesia.

Chauvenet's criterion is commonly used for rejection of outliers from sample datasets in engineering and physical science research. Measurement and uncertainty textbooks provide conflicting information on how the criterion should be applied and generally do not refer to the original work. This study was undertaken to evaluate the efficacy of Chauvenet's criterion for improving the estimate of the standard deviation of a sample, evaluate the various interpretations on how it is to be applied, and evaluate the impact of removing detected outliers. Monte Carlo simulations using normally distributed random numbers were performed with sample sizes of 5–100,000. The results show that discarding outliers based on Chauvenet's criterion is more likely to have a negative effect on estimates of mean and standard deviation than to have a positive effect. At best, the probability of improving the estimates is around 50%, which only occurs for large sample sizes.

Poultry Farming

Trace elements in the body of the bird are in small quantities, but their role in productivity remains important. In order to get a quality carcass at the slaughterhouse, you need a constant supply of nutrients and, last but not least, microelements. Zinc and Manganese are essential trace elements that affect the growth and development of birds. And their deficiency in the body has a negative effect on the productivity of birds. In the diet of broilers trace elements are mainly added with a premix in the form of inorganic salts (sulfates, carbonates). However, these micronutrient compounds in the body of the bird are insufficiently absorbed, and increasing the dose of their introduction can cause toxicosis. Therefore, in order to prevent microelementosis, it is more appropriate to use organic compounds (chelates), which have a much higher level of bioavailability and less release into the environment. This review article describes the prophylactic efficacy of Zinc and Manganese chelates in micronutrient deficiencies in broiler chickens and laying hens. With a deficiency of a particular trace element develop metabolic disorders and other pathologies (perosis, etc.). Based on the presented data, it can be concluded that the use of organic forms of trace elements in poultry feeding is a better alternative to inorganic sources, as they can be used in smaller quantities. But due to their greater bioavailability, they are better absorbed, which has a positive effect on the productivity of broilers. Since knowledge about the use of chelated forms of trace elements in comparison with inorganic forms (salts, sulfates, etc.) in the diet of poultry is still poorly understood, it is necessary to further conduct research to prevent micronutrient deficiencies in these compounds.

Cash distribution by stock buyback is one ways to increase stockholder wealth. This study is to analyze the effect of misprice (misvaluation) and leverage on stock buyback. Limited prior study discussed about stock buyback and misprice especially in Indonesia, theoritically, in Indonesia not only firm with undervalue stock do stock buyback but also firm with overvalue stock. Stock buyback can increase the stock prices, but the implementation in Indonesia is still small. Non-financial firms listed on the Indonesia Stock Exchange from 2010 to 2017 used in this study. Samples were taken by a purposive sampling method based on certain criteria. The data analysis techniques use multiple linear regression statistical analysis. The results showed that misprice has a positive effect on buyback. The different thing found in Indonesia because overvalued firms hold stock buyback. Leverage has a negative effect on stock buyback. Firms with leverage below the target tend to do a stock buyback. In addition, the stock buyback also used to correct prices (for undervalued stock to be fair). The implication in this study is stock buyback not only viewing to correct prices but also giving a signal to the market that the firm is in a good fundamental condition.

Determinar la composición corporal y las diferentes características físicas y condicionales fue el primer objetivo planteado en este estudio, donde se valoraron a 45 jugadores de balonmano masculino de la Región de Murcia, correspondiente a la categoría juvenil. Los clubes analizados han sido el Murcia, Alhama, Jumilla y Águilas. El segundo objetivo de este trabajo consiste en establecer diferencias entre los equipos valorados y las líneas de juego de carácter ofensivo. El proceso de recogida de datos antropométricos se llevó a cabo siguiendo el protocolo estipulado por el ISAK. El análisis estadístico realizado fue en primer lugar descriptivo y, posteriormente, un análisis inferencial para establecer las diferencias estadísticas entre los distintos equipos y sus líneas de juego, en todas las variables de estudio. La valoración condicional se centró básicamente en la determinación del somatotipo, en la evaluación de la velocidad de lanzamiento y en la fuerza isométrica de tren superior. Los equipos de la parte superior de la tabla presentan valores superiores en las variables antropométricas pero sin ser estadísticamente significativas estas diferencias. Se constata la importancia de la mesomorfia como característica predominante en el somatotipo del jugador de balonmano. Las mayores velocidades se alcanzaron en los lanzamientos en los que hay desplazamiento previo.Abstract: The aim of this study was two fold, first to determine the body composition, physical and conditional characteristics of male handball players, who were playing in juvenile level in Murcia. A Second objective was to establish differences among the teams evaluated and offensive playing lines. The teams analyzed were playing in Murcia, Alhama, Jumilla and Águilas. 45 juvenile male handball players participated in this study. Anthropometric data were collected following ISAK protocols. A descriptive statistical analysis was made in order to obtains means and standard deviation of the simple. An ANOVA analysis was performed in order to establish differences among teams and its playing lines. The somatotype, throwing velocity and grip were analyzed in all teams The best teams show higher values in anthropometric variables than the worts, but these differences does not reach statistical significance. Mesomorphy is a very important characteristic in handball player. Higher throwing velocities were reach in throwings with previous displacements.

A prevailing notion in experimental psychology is that individuals' performance in a task varies gradually in a continuous fashion. In a Stroop task, for example, the true average effect may be 50ms with a standard deviation of say 30ms. In this case, some individuals will have greater effects than 50ms, some will have smaller, and some are fore-casted to have negative effects in sign - they respond faster to incongruent items than to congruent ones! But are there people who have a true negative effect in Stroop or any other task? We highlight three *qualitatively different* effects: negative effects, null effects, and positive effects. The main goal of this paper is to develop models that allow researchers to explore whether all three are present in a task: Do all individuals show a positive effect? Are there individuals with truly no effect? Are there any individuals with negative effects? We develop a family of Bayesian hierarchical models that capture a variety of these constraints. We apply this approach to Stroop interference experiments and a near-liminal priming experiment where the prime may be below and above threshold for different people. We show that most tasks people are quite alike - for example everyone has positive Stroop effects and nobody fails to Stroop or Stroops negatively. We also show a case that under very specific circumstances, we could entice some people to not Stroop at all.

This paper investigates the relationship between CEO visibility and corporate risk-taking. The empirical results show that more visible CEOs tend to take more risk. A one-standard-deviation shock in the CEOs media exposure results in a 6.53% rise in total risk. We further investigate the channels of risk-taking activities and find that more visible CEOs seek more R&D investments. The positive effect of CEO visibility on firm risk policies is clearly of concern to bondholders. Consistent with this view, we report that CEO visibility has a significant negative effect on firm credit ratings. Our results highlight the importance of CEO visibility on a crucial corporate outcome — the extent of corporate risk-taking.

This research is new in its attempt to take future time orientation, morningness orientation, and prospective memory as measures of mental prospection, and to examine a three-factor model that assumes working memory, mental prospection, and cognitive insight are independent but related higher-order cognitive constructs by using confirmatory factor analysis (CFA). The three-factor model produced a good fit to the data. An alternative one-factor model was tested and rejected. The results suggest that working memory and cognitive insight are distinguishable, related constructs, and that both are distinct from, but negatively associated with, mental prospection. In addition, structural equation modeling (SEM) showed that working memory had a strong positive effect on cognitive insight and a moderate negative effect on mental prospection.
