Common Mode Voltage (CMV) produced in Pulse Width Modulated (PWM) inverters causes premature failure of the motor bearings. Therefore CMV has to be reduced. Pre-calculated Harmonic Eliminated PWM (PHEPWM) scheme is proposed to reduce the CMV in three phase inverter. The accurate switching angles have to be calculated by solving nonlinear equations. The switching angles for the pre-calculated harmonic elimination technique are calculated by using Newton-Raphson algorithm. The proposed modulation scheme is evaluated and tested at various switching frequencies for different modulation index. With this PHEPWM it is possible to eliminate the lower order harmonics, 5th, 7th , 11th, 13th, 17th, 19th, and 23rd from the inverter output voltage for any desired value of the fundamental component in for any desired modulation index. The CMV in inverter using PHEPWM method is compared with CMV produced using classical Sinusoidal PWM (SPWM) method.

In recent times there is a huge demand in reduced switched multilevel inverter. The multilevel inverter is one of the attractive features in harmonics elimination. This paper proposes single source nine level inverter with reduced switching devices for single phase AC applications. The conventional cascaded and other multilevel inverter comprises of more number of switches, passive components as well as sources. This makes the system larger in size, weight as well as less cost effective. The proposed multilevel inverter has the ability of producing nine levels with reduced number of switches and source. In addition to that the single source nine level inverter utilizes the simplified control algorithm which reduces the complexity. The Sinusoidal Pulse Width Modulation (SPWM) scheme is one of the most common control techniques which have the simple structure. The operation of the circuit and control algorithm is discussed in detail. The results are verified by the Matlab/Simulink which shows the value and righteousness of the system.

The current scenario of energy demands in India have waded new research areas for hunting the alternative energy resources to compensate the polluting non renewable resources. It brings larger importance to the idea of harvesting the frictional energy between the Roads and the vehicular tyres. This is exerted as a stress on the road surface accompanied by Heat dissipation. This wasted form for energy can be made productive by using Piezoelectric Generator and Thermoelectric Generator. Piezoelectric Generator generates electricity in response to stress acting on its mechanical axis while Thermoelectric Generator generates power when an ambient temperature difference is provided. These are embedded below the road surface with suitable insulations and proper structure to improve its performance. This system would have very low capital cost when compared to the total cost of power generation, transmission and distribution in conventional power generation methods with the life time of this system in concern . The pollution free electricity thus generated from the road by using these generators can be stored in a battery and later used for the domestic electrification. This method will be best suited for the electrification of all time loads like Traffic signals, street lights, lighting especially in highways.

The Computational Analysis of Kinematics of 3 – Links Articulated Robotic Manipulator has been presented in this. The design of robot manipulators requires accurate computational analysis, involving the geometric position of the linking arms. The method of Forward Kinematics and Inverse Kinematics were employed in estimating the robotic arm’s position with respect to link lengths and angle, in which the angle required to move the end effector to a desired position is estimated and determined. A three link robotic arm with a rigid rotational base was also illustrated using free body diagrams, and computational estimation of the required parameters. The outcomes of the forward kinematics reveals that the robot end effector position can be estimated using the values of x, y, and z coordinates thereby providing a better means of controlling or adapting robot’s arm/motion to its environment.

Authors: Linning Lisa M. , Kearney Christopher
Published: January 2020

Therapy to address PTSD symptoms in maltreated youth has received increased research attention in recent years.  However, little data are available regarding the treatment of youth temporarily housed in shelter care facilities whose parents are unavailable or inaccessible.  The present study examined a brief group therapy protocol for such youth in a county-operated shelter.  Participants received 1-6 sessions of treatment depending on their length of stay at the shelter.  Treatment components included psychoeducation, anxiety management, cognitive restructuring and coping skills, emotional expression, mindfulness, brief exposure, boundary setting, and journaling.  Results revealed a significant reduction in PTSD symptoms overall and that number of group therapy sessions mediated pre-treatment and post-treatment scores on various dependent measures.  In addition, level of pre-treatment dissociation predicted reduction in PTSD levels.  These preliminary results indicate that brief treatment for youth temporarily housed in a shelter care facility can provide some amelioration of PTSD-related symptoms.

Published: January 2020

Moderate-to-vigorous physical activity (MVPA) may deter adolescents from smoking initiation; such an approach requires knowledge of psychosocial risk and protective factors associated with both physical activity and smoking experimentation. This paper examines such psychosocial factors across four groups of adolescents identified by crossing smoking experimentation (yes/no) with completes adequate MVPA (yes/no). In 2008-09, 1,098 Mexican origin youth (50.4% girls, mean age 14.3 years (SD=1.04)) provided data on smoking behavior, physical activity, alcohol use, acculturation, peer and parental smoking, BMI, body image, smoking outcome expectations, anxiety, subjective social status (SSS), body image and sensation-seeking tendencies. We conducted Pearson’s 2 tests to examine associations between a) MVPA and smoking and b) demographic variables and the four groups identified by crossing smoking experimentation with MVPA. Next, adjusting for age and gender, we completed analysis of covariance to examine differences in psychosocial factors across the four groups. In our sample, 22.4% had experimented with cigarettes, and 29.3% completed adequate MVPA. Both behaviors were more prevalent among boys. Although not statistically significantly higher, 32.9% of experimenters completed adequate MVPA compared to 28.3% among non-experimenters. Experimenters who complete adequate MVPA reported the highest levels of thrill and adventure seeking, while those who complete inadequate MVPA reported lower SSS and more body image concerns than non-experimenters (p<0.05 for all). Our findings highlight an opportunity to address MVPA as an alternative to smoking among Mexican origin youth with high thrill and adventure sensation seeking tendencies, 82% of whom have experimented and 69% of who complete MVPA.
Air pollution and the school air environment.
Authors: Fsadni Peter , Montefort Stephen
Published: January 2020

There is growing concern about the association of school indoor air quality (SIAQ) with asthma, rhinitis and rhinoconjunctivitis.Students and school staff alike deserve the highest standards of school air quality possible thus ensuring a safe and productive environment for our childrens’ education. Existing studies highlighted the presence of  several air pollutants  present within school classrooms which have a direct association with poor health and student performance. Very little data exists about school air quality in countries situated in subtropical regions including small island nations such as Malta. The most commonly identified pollutants include CO2, CO, volatile organic compounds (VOC), formaldehyde, O3,  NO2 , and particulate matter (PM 10, PM 2.5). These have been mainly associated with an increased risk of asthma and rhinitis mainly in atopic pupils after correcting for alternative exposures. Air quality improvement is an essential measure to help prevent respiratory atopic disease in school occupants. The absence of a European SIAQ monitoring programme highlights the urgent need for more research in this field so as to issue the necessary evidence based recommendations specific to the individual countries.
Economic theory meets clinical practice: moral hazard
Authors: Vasylyeva Olga
Published: January 2020

Economic theory must be tested by reality to prove that the goal is achievable and reproducible. However, health care economics do not always theorize based on modern-day medical practice, which results in detachment of some economic recommendations from real-life medicine. The theory of “moral hazard” assumes that patients will utilize more medical services if they transfer the risk of cost to insurances. In this article, we will revisit the understanding of appropriate avoidance of medical services and incorporate no-show rate, avoidance of care, and nonadherence into the concept of health services utilization. The primary goal of this interdisciplinary commentary is to bridge economic theory with clinical practice. It is written from the perspective of a clinical practitioner, who applies realities of everyday medicine to economic reasoning. The author hopes that this abstract will extend the field of vision of health care economics.
Fusion of Elliptical Extended Object Estimates Parameterized with Orientation and Axes Lengths
Authors: Thormann Kolja , Baum Marcus
Published: January 2020

This article considers the fusion of target estimates stemming from multiple sensors, where the spatial extent of the targets is incorporated. The target estimates are represented as ellipses parameterized with center orientation and semi-axis lengths and width. Here, the fusion faces challenges such as ambiguous parameterization and an unclear meaning of the Euclidean distance between such estimates. We introduce a novel Bayesian framework for random ellipses based on the concept of a Minimum Mean Gaussian Wasserstein (MMGW) estimator. The MMGW estimate is optimal with respect to the Gaussian Wasserstein (GW) distance, which is a suitable distance metric for ellipses. We develop practical algorithms to approximate the MMGW estimate of the fusion result. The key idea is to approximate the GW distance with a modified version of the Square Root (SR) distance. By this means, optimal estimation and fusion can be performed based on the square root of the elliptic shape matrices. We analyze different implementations using, e.g., Monte Carlo methods, and evaluate them in simulated scenarios. An extensive comparison with state-of-the-art methods highlights the benefits of estimators tailored to the Gaussian Wasserstein distances.

The role of Epstein-Barr viral infection and hepatitis B and C in liver pathology
Authors: Solomay T. V. , Semenenko T. A. , Ivanova M. Yu.
Published: January 2020

A review of scientific literature data on clinical and epidemiological characterization of viral hepatitis B, C and Epstein-Barr viral infection is presented. Scopus, Web of Science, MedLine, The Cochrane Library, PubMed, CyberLeninka, RSCI databases were used to find the necessary literature. It was shown that Epstein-Barr virus along with hepatitis B and C viruses plays a significant role in the development of virus-mediated autoimmune liver diseases, as well as other organs (intestine, heart, kidneys, thyroid gland, etc.). The similarity of these nosologies is also evident in the nature of the course of the disease: the presence of a primary infection in a manifest or latent form, with possible subsequent chronization of the process and its periodic reactivation. Wide distribution of pathogens in the human population determines the possibility of mixed infections with Epstein-Barr virus and hepatitis B and C viruses, however, this problem has not been adequately described in the scientific literature. The review suggests that the role of Epstein-Barr virus in the development of liver diseases and extrahepatic pathology should not be ignored, and the combination of this pathogen with hepatitis B and C viruses required further in-depth studies.

Hepatitis A is a widespread viral infection. The HAV strains of “human” and “monkey” origin are similar in their morphological and antigenic properties, but differ genotypically.The aim of this research was a comparative study of serological and molecular-genetic markers of HAV infection in monkeys born at the Adler Primate Center and in those imported from different countries.Material and methods. Fecal samples (n = 313) and serum (n = 266) from various species of monkey using ELISA and RT-PCR were studied.Results and discussion. The frequency of anti-HAV-IgG was high (78.9%) in imported animals (vervet monkeys from Tanzania and cynomolgus monkeys from Vietnam) and as well as in various species of monkeys (rhesus monkeys, cynomolgus monkeys, green monkeys and papio hamadryas) of the Center (88.6%). At the same time, in the imported monkeys, the markers of “fresh” HAV infection (IgM-27.2%, Ag-HAV-16.7%, RNA-22.0%) were detected significantly more often (p 0.05) than in monkeys kept at the Colony (IgM-7.5%, HAV-Ag – 5.2%, RNA – 3.6%). In general, anti-IgG reactivity ranged from 1.064 to 2.073 OD450, anti-IgM ranged from 0.546 to 1.059 OD450. The number of HAV-Ag was 0.496 – 1.995 OD450. RNA HAV only in rhesus monkeys and cynomolgys monkeys born at the Colony, as well as in imported vervet monkeys was detected.Conclusions. The data obtained indicate a wide circulation of HAV among monkeys born in the Adler Primate Center and among the imported animals. Markers of “fresh” HAV infection varied depending on the species of monkeys and their origin.

The article discusses the issues of improving the technology of cutting teeth of cylindrical gears using modular precast disk milling cutter in various production conditions for gear milling, reducing the cost of tooling materials and facilitating the manufacture of precast disk mills by changing the design. The essence of this design is that when cutting teeth into gears with an involute profile, radial runout is eliminated to a minimum, since the gear cutting operation is carried out on the machine in which the turning was performed. The proposed new gear processing technology – with an involute profile shape and engineered efficient design of prefabricated disk cutters. The main place in the article is given to the design parameters of gear cutting mills, as well as their advantages and disadvantages. Much attention is paid to the determination of the structural and geometric parameters of cutters with various cutting patterns. The described methods are applicable for the design of tools in small-scale production of gears.

The study deals with the field experiment on the efficiency of soil tillage technology (conventional and alternate tillage) and the amount of crop residue retention of ozone trunks of winter wheat-mung-cotton under the conditions of typically irrigated grey-earth soil of the Tashkent region. The study results showed the compaction of 0-30 and 30-50 cm soil layers with summer green mung grown under permanent beds compared to the existing technology for soil tillage. The efficiency of minimum soil tillage for summer crops with a decreased number of tillage operations under minimum soil till resulted in earlier seeding of summer crops and improved soil water permeability compared to the traditional soil tillage. Despite the amount of crop residue retained for mulching, the grain yield of summer green gram was 1.1 to 1.2 t ha-1 under traditional tillage and 1.0 to 1.1 t ha-1 under alternate tillage. The highest seed cotton yield was reached with 100% residue retention for both conventional and alternate tillage. However, the seed cotton yield was 0.38 t ha-1 higher under traditional tillage in comparison with alternate tillage.

The study proposes innovative equipment designed to strengthen the forage base of fish farms. The device of the latest technology is protected from external influences as the power supply is located inside the device. It is equipped with modern energy-saving lamps and is able to work for a long time without additional electricity. The proposed innovative fish farming device provides fish with natural nutrients – flying insects. The device works as follows: the surface and lower part of the protective cap is yellow, and the light flux emitted by the optical radiation source (lighting), reflecting from the coloured cap and the surface of the water, glows differently according to the law of interference. This makes it more attractive to insects around the pond. The light source is surrounded by a high-voltage grid, whose task is to kill insects that fly to the device. The distance between high-voltage grid cells is 5-8 millimetres. Insects that strive for light pass through high-voltage cells. In this process, insects die in high-voltage grids and fall into the pond. The system allows fish to feed on natural nutrients such as insects.
