Web-Based Student Score Application Design at Husni Thamrin Private Junior High School, Medan

Value data processing is one of the most important parts of school operations and activities. Husni Thamrin Medan Private Middle School, one of the schools that organizes an educational process based on the 2013 Curriculum, manages value data through manual and separate input by each teacher. It is hoped that through the development of a web application-based value management system, value data processing can be carried out more easily and integratedly. To implement the use of this application, training is needed for teachers so they can get to know the features and how to use the application

Residual Current Measurement using Helmholtz Coil Configuration with different Current Flow

For leakage current safety, Residual Current Device (RCD) has been well known. The purpose of this work is to make the employment of low price components to measure residual current feasible and the Residual Current Device (RCD) must to be taken into account because it is a well known device for leakage current safety. For this purpose, experiments employing the Helmholtz Coil Configuration were performed with the different current flow. Furthermore, the residual current was formulated and simulated through the software Easy Java Simulation (EJS). The results showed that it is possible to move the magnet into different angles using leakage current with linear gradient as low as 0.382 degree/mA. Finally, it was proposed a way to increase the sensitivity and to reduce the hysteresis phenomenon

Effect of Stromal Vascular Fraction and Platelet-Rich Plasma Combination on Polymorphonuclear Cells in Wistar Rats Anal Trauma Model

Introduction: By relying on polymorphonuclear (PMN) cells, stromal vascular fraction (SVF) and platelet-rich plasma (PRP) contribute significantly in the healing process. Through anal trauma model, this study examined the effect of SVF and PRP combination on PMN counts in vivo. Method: Three groups of twenty-eight eligible Wistar rats anal trauma model randomly assigned to receive SVF and PRP combination (Group A), normal saline (Group B), or healthy controls (Group C). On days 1, 7, and 14, we examined at PMN cell counts in Groups A and B. Group C were sacrificed early to acquire baseline data on PMN cells. Results:  On the first day, Group A had more PMN cells than Group B, but this difference faded by days 7 and 14. On day 1, the test revealed a significant increase in PMN cells (p=0.002). Conclusion:  Combining SVF and PRP can improve PMN cells' acute phase of anal damage repair in viv

EDUCATION GAME AS AN EFFORT DELIGHTFUL LEARNING IN THE ELEMENTARY SCHOOL

This study aims to develop a thematic learning media in the era of industrial revolution 4.0 by using educational games for elementary students that are valid, practical and effective. Thematic learning media using educational games is closely related to innovation and the use of technology following the demands of the industrial revolution 4.0 era to increase student’s attractiveness in learning. Thematic media learning was the result of development by using adobe flash CS6 program. The contained of media was thematic learning that integrates of several subjects. The development model used was 4-D (define, design, develop, disseminate). The research data was obtained from the validity test (media validation sheet), practicality (student and teacher response questionnaire), and effectiveness (student learning activities and results). Data were analyzed descriptively. The results showed that the thematic learning media was valid (media content according to curriculum, attractive design and layout, ease of operation, easy to understand students' language, and clear presentation according to student characteristics), practical (clear contents and objectives, easy to read, attractive appearance, and student interest increases), and effective (can increase student activity and learning outcomes). Learning media using educational games can create a fun learning proces

In-Silico Study of Novel Folate Analogues as Anticancer which Inhibits Dihydrofolate Reductase

Dihydrofolate reductase (DHFR) has an important function in folic analogues biosynthesis which is used as nutrition for cells. In a specific cancer cell, DHFR has bigger expression than normal cells therefore it is good candidates as target to cancer chemotherap. In this research the screening have been done to 10-N-(4’-bromobenzoyl) folic acid and 10-N-(p-toluoyl) folic acid by in silico method. The result of molecular docking shows that those two compounds have more stable interaction than other DHFR inhibitors (methotrexate) but those two compound do not follow the Lipinsky’s rule of 5 which is affected to its bioavailability

Less than 50% sublattice polarization in an insulating S=3/2 kagome' antiferromagnet at low T

We have found weak long range antiferromagnetic order in the quasi-two-dimensional insulating oxide $KCr_3(OD)_6(SO_4)_2$ which contains Cr$^{3+}$ S=3/2 ions on a kagom\'{e} lattice. In a sample with $\approx$ 76% occupancy of the chromium sites the ordered moment is 1.1(3)$\mu_B$ per chromium ion which is only one third of the N\'{e}el value $g\mu_BS=3\mu_B$. The magnetic unit cell equals the chemical unit cell, a situation which is favored by inter-plane interactions. Gapless quantum spin-fluctuations ($\Delta/k_B >$T_N$= 1.6K are the dominant contribution to the spin correlation function,$S(Q,\omega)$ in the ordered phase.Comment: 18 pages, RevTex/Latex, with 6 figure

Neutron Scattering study of Sr_2Cu_3O_4Cl_2

We report a neutron scattering study on the tetragonal compound Sr_2Cu_3O_4Cl_2, which has two-dimensional (2D) interpenetrating Cu_I and Cu_{II} subsystems, each forming a S=1/2 square lattice quantum Heisenberg antiferromagnet (SLQHA). The mean-field ground state is degenerate, since the inter-subsystem interactions are geometrically frustrated. Magnetic neutron scattering experiments show that quantum fluctuations lift the degeneracy and cause a 2D Ising ordering of the Cu_{II} subsystem. Due to quantum fluctuations a dramatic increase of the Cu_I out-of-plane spin-wave gap is also observed. The temperature dependence and the dispersion of the spin-wave energy are quantitatively explained by spin-wave calculations which include quantum fluctuations explicitly. The values for the nearest-neighbor superexchange interactions between the Cu_I and Cu_{II} ions and between the Cu_{II} ions are determined experimentally to be J_{I-II} = -10(2)meV and J_{II}= 10.5(5)meV, respectively. Due to its small exchange interaction, J_{II}, the 2D dispersion of the Cu_{II} SLQHA can be measured over the whole Brillouin zone with thermal neutrons, and a novel dispersion at the zone boundary, predicted by theory, is confirmed. The instantaneous magnetic correlation length of the Cu_{II} SLQHA is obtained up to a very high temperature, T/J_{II}\approx 0.75. This result is compared with several theoretical predictions as well as recent experiments on the S=1/2 SLQHA.Comment: Figures and equations are rearrange
