Authors: Ân Văn Viết Thiên , Hải Lê Đăng 
Published: July 2019

Nghiên cứu này đánh giá ảnh hưởng của hàm lượng tro bay và nano carbon đến các tính chất cơ lý cũng như co ngót và khả năng kháng nứt theo phương pháp vòng hạn chế (Ring-Test) của bê tông chất lượng siêu cao (UHPC). Kết quả nghiên cứu cho thấy khi tăng hàm lượng tro bay thay thế xi măng thì tính công tác và co ngót của UHPC sẽ được cải thiện. Tuy nhiên, cường độ nén ở tuổi 28 ngày và khả năng kháng nứt của UHPC đạt được cao nhất ở 20% tro bay thay thế xi măng theo thể tích. Khi sử dụng nano carbon thì cường độ nén ở 28 ngày tuổi và khả năng kháng nứt của UHPC tăng lên.

Bài báo này trình bày các nguyên tắc thiết kế chung và các phương pháp tính toán đơn giản cho cấu kiện sàn bê tông cốt thép, được quy định trong tiêu chuẩn châu Âu EN 1992-1-2 về thiết kế kết cấu bê tông cốt thép trong điều kiện cháy. Quy trình tính toán theo ba phương pháp đơn giản bao gồm tra bảng, đường đẳng nhiệt và phương pháp phân lớp được trình bày cụ thể và minh họa thông qua ví dụ tính toán. Ảnh hưởng của một số thông số quan trọng như lớp bê tông bảo vệ, hàm lượng cốt thép và thời gian cháy được khảo sát. Kết quả cho thấy khi tăng chiều dày lớp bê tông bảo vệ và hàm lượng cốt thép thì khả năng chịu lực khi cháy của sàn tăng lên, tuy nhiên khả năng chịu lực chỉ tăng đến một giá trị nào đó thì lại giảm dần do chiều cao làm việc giảm. Khi thời gian cháy tăng lên thì khả năng chịu lực khi cháy của sàn cũng giảm đi. Nếu vẽ giá trị mô men ngoại lực và khả năng chịu lực trên cùng một biểu đồ thì dễ dàng xác định được khả năng chịu lực khi cháy của sàn bê tông cốt thép.

Published: July 2019

Even though there are many issues surrounding dividend policy, dividend remains one of the main goals for investors to achieve. The aim of this study is to find out determinants of dividend policy in Indonesia. Most of the samples in observed period have varieties of dividend policies. Data for this study was collected from 258 business entities in the period between 2009 and 2012. For hypotheses testing, a binary logistic regression and factor analysis were used. The result from binary logistic regression showed that share price, earnings per share and current ratio are significant factors for dividend policy, while debt to equity ratio and corporate tax are insignificant. The insignificance of debt and tax was probably due to current ratio affected by accounting adjustments. Even though debt and tax are insignificant, they could not be ignored. Using factor analysis, it is confirmed that, most companies in this study have a similar objective through dividend policy, which is to maximize their share value in the stock market by considering profitability and liquidity on cash availability and also debt and tax. Dividends as a form of “trust value” offered by companies to their shareholders stimulate the trust of investors or shareholders and resulting the increase of share price.

Introduction: This article reviews the treatments available for patients with T2DM, with an emphasis on agents introduced within the last decade. Materials and Methods: This review is based on a search of Medline, the Cochrane Database of Systemic Reviews, and citation lists of relevant publications. Subject heading and key words used include type 2 diabetes mellitus, prevalence, current diagnosis, and current treatment. Only articles in English were included.
Materials & Methods: Screening and diagnosis is still based on World Health Organization (WHO) and American Diabetes Association (ADA) criteria which include both clinical and laboratory parameters. No cure has yet been found for the disease; however, treatment modalities include lifestyle modifications, treatment of obesity, oral hypoglycemic agents, and insulin sensitizers is still the recommended first line medication. Other effective medications include non-sulfonylurea secretagogues, thiazolidinediones, alpha glucosidase inhibitors, and insulin. Recent research into the pathophysiology of type 2 DM has led to the introduction of new medications like glucagon-like peptide 1 analogoues: dipeptidyl peptidase-IV inhibitors, inhibitors of the sodium-glucose cotransporter 2 and 11ß-hydroxysteroid dehydrogenase 1, insulin-releasing glucokinase activators and pancreatic-G-protein-coupled fatty-acid-receptor agonists, glucagon-receptor antagonists, metabolic inhibitors of hepatic glucose output and quick-release bromocriptine.

Published: July 2019

This experiment aimed to measurenment of the electricity and dielectric characteristic of onion (Allium cepa). In this study, the onion have been done through the variation of frequency and temperature. The frequency was setup in 30 different values from 100 Hz -1 MHz with the temperature are from 26 0 C up to 40 0C with each increase of 2 0C. The measurement was performed on AC current in 1 kHz and input voltage is one volt. The ions through to the membrane was measured as a conductance value by using LCRmeter that connected with two pieces of AgCl electrodes on both side of the membrane. Beside that, the conductance (G) was measured by the variation temperature of the solution. The results based on the electric characteristics variation of the frequency shows that the electricity of the onion membrane from the conductance itself is tend to increase and the capacitance is decrease due to increasing of the frequency. However, the conductance and the capacitance of the soaked onion membrane is increase doe to increase of the temperature than the original onion membrane. In adddition, the increasing of conductance to temperature was plotted on ln G to 1/T curve. The slope or gradient of the curve is used to determine the change of the self-energy of the membrane and its pore radius. Self-energy of ion which obtained from non-washed and washed and soaked (with distilled water) membrane is respectively 7,66967 x 10-21 J or 0,04787 eV dan 1,2156 x 10-19 J or 0,7869 eV ( 1 joule = 6,2415 x 1018 eV) and the average of pore membrane radius is 2,00 x 10-9 meter (2,00 nm) and 1,26 10-10 meter (0,126 nm). Based on the results the onion membrane could be a good membrane for established the electrisity anf the dielectricity.
