Simulation of Soil Compaction by a Tractor Passing

Several methods for agricultural soil compaction evaluation are known. However, there is a lack of knowledge about a soil elasticity, which could be an important factor for final level of compaction. The paper deals with a possibility of evaluation of soil elasticity using automatic computerized oedometer. A simulation of tractor passing was performed as a part of research focused on the monitoring of soil conditions in vineyards. Cyclic loading test of five loading cycles (loading 300 kPa and un-loading 5 kPa) was performed and vertical deflection was observed, which changed in dependency on change of vertical stress. Course of vertical deformation indicates the ability of soil to relax when the load subsides. The paper presents pilot results, that show good potential of using oedometer for soil elasticity evaluating. Information on the elastic behaviour of soil will make it possible to design and apply means for improving soil elasticity and thus help to mitigate the effects of soil compaction.

Nodes with the highest control power play an important role at the final level of cooperation in directed networks

Controllability of complex networks aims to seek the lowest number of nodes (the driver nodes) that can control all the nodes by receiving the input signals. The concept of control centrality is used to determine the power of each node to control the network. The more a node controls the nodes through connections in the network, the more it has the power to control. Although the cooperative and free-rider strategies and the final level of cooperation in a population are considered and studied in the public goods game. However, it is yet to determine a solution to indicate the effectiveness of each member in changing the strategies of the other members. In a network, the choice of nodes effective in changing the other nodes’ strategies, as free-riders, will lead to lower cooperation and vice versa. This paper uses simulated and real networks to investigate that the nodes with the highest control power are more effective than the hubs, local, and random nodes in changing the strategies of the other nodes and the final level of cooperation. Results indicate that the nodes with the highest control power as free-riders, compared to the other sets being under consideration, can lead to a lower level of cooperation and are, therefore, more effective in changing the strategies of the other nodes. The obtained results can be considered in the treatment of cancer. So that, destroying the tumoral cells with the highest control power should be a priority as these cells have a higher capability to change the strategies of the other cells from cooperators to free-riders (healthy to tumoral).

Analisa Faktor-Faktor yang Berhubungan dengan Perilaku Makan Mahasiswa Tingkat Akhir Fakultas Kedokteran Universitas Pembangunan Nasional “Veteran” Jakarta Tahun 2020

Background: Eating behavior is the way a person thinks, is knowledgeable, and has views about food which is expressed in the form of eating. Deviant eating behaviors can be caused by a variety of factors, one of which is the stress condition commonly experienced by final-level students.. Objective: This study aims to determine the factors associated with the eating behavior of final-level students. Methods: The study used cross-sectional analytical studies on 49 respondents with stratified random sampling techniques. Data was collected using a questionnaire conducted online via google-form. The questionnaire that has been made by previous researchers has been tested for validity and reliability. Results: The results showed that the majority of respondents had female gender (73.5%), good eating behavior (69.4%), positive body image perception (61.2%), moderate stress level (51%), and positive emotional eating (51%). Based on bivariate analysis there was a relationship between perception of body image and eating behavior (p = 0.029). Conclusion: Therefore, students are advised to build good confidence in order to create a positive perception of body image, so that they can have good eating behaviors with high levels of productivity. Keywords: eating behavior; gender; body image perception; stress; emotional eating; final year student.

Number of type 2 diabetes patients achieving HbA1c goal and Related Factors in Brazil: A real world evidence study

Background Despite the clinical advances in the management of type 2 diabetes mellitus (T2DM) over the past decades, in the US, nearly 48% of patients do not achieve the ADA recommended glycemic goal of glycated hemoglobin (HbA1c) below 7.0%1. The Brazilian Guidelines for the Treatment of T2DM has established the same goal of HbA1c below 7.0%2, but the data for the rate of glycemic goal achievement in Brazil is lacking. The aim of this study was to determine the rate of HbA1c goal achievement among Brazilian patients receiving antidiabetic therapy and investigate its relation to other clinical and demographic covariates. Methods Using a cross-sectional database analysis from a group of private clinics in São Paulo, Brazil, this Real Word Evidence study evaluated 1034 patients with T2DM, which were being treated with at least one antidiabetic agent for a minimum of three months and had a basal level of Glycated Hemoglobin (HbA1c) above 7.0%. The number of patients that did not achieve the therapeutic target of HbA1c below 7% was calculated. Demographic and clinical characteristics were collected and a correlation analysis with the treatment target achievement was performed. Results The average age of the population was 60.5 years and gender were equally distributed. A total of 60.3% of the patients did not achieve the target of HbA1c below 7% after a minimum of three months treatment with one or more antidiabetic agents. The average time between HbA1c basal to final was 9.9 months. The average basal level of HbA1c was 9.9% ± 2.2 and the final level was 7.8% ± 1.9. In the univariate analysis a statistically significant difference was observed in the following clinical variables: age, total cholesterol level, LDL level, basal and final HbA1c, time to HbA1c final measure, treatment time, and number of antidiabetic agents. Conclusion In this retrospective real-world study, only 40% of patients achieved the glycemic target of HbA1c below 7% after at least 3 months of treatment with one or more antidiabetic agent. The average initial HbA1c was 9.9% and the final level was 7.8%. Patients not at goal were older and had more comorbidities, which highlight the challenge that represents the management of diabetes in Brazil. This study confirms previous published data that T2DM glycemic targets are difficult to achieve and the reasons for this are complex and multifactorial
