Treatment of Gingival Recession

Gingival recession is an intriguing and complex phenomenon. Recession frequently disturbs patients because of sensitivity and esthetics. Many surgical techniques have been introduced to treat gingival recession, including those involving autogenous tissue grafting, various flap designs, orthodontics, and guided tissue regeneration (GTR). This article describes different clinical approaches to treat gingival recession with emphasis on techniques that show promising results and root coverage

Reflection of electromagnetic waves from mixtures of plane gravitational and scalar waves

We consider colliding wave packets consisting of hybrid mixtures of electromagnetic, gravitational and scalar waves. Irrespective of the scalar field, the electromagnetic wave still reflects from the gravitational wave. Some reflection processes are given for different choice of packets in which the Coulomb-like component $\Psi_2$ vanishes. Exact solution for multiple reflection of an electromagnetic wave from successive impulsive gravitational waves is obtained in a closed form. It is shown that a succesive sign flip in the Maxwell spinor arises as a result of encountering with an impulsive train (i.e. the Dirac's comb curvature) of gravitational waves. Such an observable effect may be helpful in the detection of gravitational wave bursts.Comment: 20 pages, 3 ps figures, small typos corrected, published versio

PROFESIONALISME GURU DI ERA REVOLUSI INDUSTRI 4.0

Revolution 4.0 requires teachers to be professional in the world of education. The role of teachers in the world of education is very urgent, because the condition of learning is the existence of a teacher. As teachers who live or are in the current global era, we are required to be creative and master technology so that it is not left behind by the current era. It is undeniable that the era of globalization requires us to be active, creative, master technology. If we cannot keep up with the current development of modern times, then we will be left behind by others

Credit of peanut to subsequent wheat under desert farming conditions in presence of diazotrophs and nitrogen fertilizers

Rotation with leguminous crops to break non-legume monocultures has been established to benefit the latter. The lacking information on this cultivation system in stressed environments encouraged the implementation of two field trials in two different locations of Ismailia desert soils. The experimental design included the cultivation of wheat subsequent to peanut in presence of diazotroph inoculation and N fertilization. Bradyrhizobial inoculation of the legume in combination with 50 kg N acre-1 resulted in the highest total biological yields of 4.24 and 5.01 kg plot-1 at the experimental sites 1 and 2, respective seed yields of 1.46 and 1.61 kg pot-1 were recorded. In case of the cereal crop, the measured acetylene reducing activities in soils of associative diazotroph-inoculated plants together with 50 kg N acre-1 were the highest being 515.8-886.2 and 616.7-1066.2 nmoles C2H4 g-1 h-1 at locations 1 and 2 respectively. The enzymatic activity of fallow-cultivated wheat generally represented ca. 95 % of that in subsequent to peanut. Irrespective of inoculation and N fertilization, the wheat biomass yield increases in residual effect-field over the fallow one were 6.4-35.1 % and 4.6-38.5 % at experimental sites 1 and 2 respectively. Increase percentages of 3.1-26.6 and 6.9-44.7 were scored as well for grain yield. The beneficial residual effect of the legume to the succeeding cereal was also extended to protein yields, increases of 4.0-14.2 % and 4.5-7.6 % were estimated for grain protein as well as 8.3-24.1 % and 8.1-35.3 % for straw protein yield. The findings of this study proved that the positively yield turnover of a legume is extended to the subsequent non-legume. Besides, the beneficial residual effects of legumes toward rotated non legumes could be magnified by diazotroph inoculation together with adequate N supply particularly in stressed environments represented, in the present study, by Ismailia sandy soil

Determination of Dominant Factors Diamond Fraud at Drinking Water Company

Research with the title Determination Factors Dominant of Diamond Fraud at Drinking Water Company with the aim to find out, describe, measure and analyze the influence of diamond fraud variables (capability, pressure, rationalization and opportunity) at Drinking Water Company The subject of this study was the Directorate of Services and Managing Water Use with the number of employees as 203 people. The data obtained were analyzed using SEM (Structural equation modeling is a statistical technique used to build and test statistical models that are usually in the form of causal models. The software used in this SEM analysis is LISREL 8.8. The results of the overall research, conceptualization and prevention of fraud through capability, pressure, rationalization and pelaang at Drinking Water Company shows that pressure is no longer a variable that has a relationship or influence on fraud variables. It is recommended to management to develop a system of controlling and monitoring opportunities that cause fraud that can arise from factors of capability, opportunities, rationalization. One of the management systems that can be applied to fraud control is the application of ISO37001: 2016 or what is known as an anti-bribery management system. Keywords: capability, rationalization, pressure, opportunities. DOI: 10.7176/EJBM/12-33-07 Publication date: November 30th 2020

Investigation of the Effect of Pipeline Size on the Cross Flow Injection Process

Injection pumps constitute an essential component for many industrial applications. The main focus of this study is to predict the effect of the size of the pipeline on the cross flow injection process. A test-rig was designed, built and equipped with three different pipelines, 1½", ¾" and ½" diameters. Comparison was made under constant line pressure of 40-bar and line flow rate of 5 liter/min, with a fixed injection pump rotational speed of 100 rpm. The main parameter tested was the injection dose capacity at different pump displacements. Cross flow mixing process is also theoretically studied using 3D-CFD analysis to show the injection cross flow behavior for the same geometry and parameters used for experimental test. Results show that increasing the size of the pipeline increases injection pump doses ability. This effect is insignificant at lower injection pump displacements, while the effect of the size of the pipeline becomes dominant when increasing the displacement. By changing the size of the pipeline from ½" to 1½" diameter injection pump dose capacity increases by 3.24% at 100% pump displacement. Selecting larger pipe sizes for injection ports is recommended whenever possible

This research was conducted at Mercubuanan Universitas .The method of data collection is using primary data from 96 students who ever use e-learning through questionnaires, direct observation of the object under study and literature study by use a sample survey methodology. The data were analyzed by using SPSS 17 software. The result of analysis for this model shows that perceived easy of use and attitude affect the intention to use e-learning. This means that the intention to use e-learning is influenced by the construct perceived ease of use and attitude. The implication of this research is relevant to the management university to consider factor of perceived ease of use and attitude in applying and developing e-learning in the University system.
