Psychological Variables of Aggression at Teenagers

AbstractManifestation of aggression in schools has become a major issue lately and teachers’ unanimous opinion is that this is a phenomenon that is likely to grow in the field of formal education. The study aimed to identify significant differences between adolescents who exhibit aggressive behaviour and those who did not manifest these behaviours regarding self-esteem and certain personality traits. The results of the study showed significant differences in terms of self-esteem and extraversion - introversion between subjects perceived as aggressors and as victims

Computer Aided Model for an Off-grid Photovoltaic System Using Batteries Only

This article will present an off-grid photovoltaic energy system based on a photovoltaic element (PV), or a group of PVs, integrated in a solar battery (SB), directly connected to an electrical battery (EB) having no DC-DC adapter (use of adapters is the most common solution existing now on in this domain). This SB must be properly adjusted to the EB, not only as voltage, but it must provide also the same amount of energy as the system when operating at its classically detected maximum power operating point. This proposed technical solution is more economically justified, compared to the classic one: SB+DC-DC+EB, due to the simple fact that the DC-DC converter is no longer required at all. A simple mathematical model for the current-voltage characteristics is also presented, followed by a comparison between the classic DC-DC converter-based solution and the newly proposed one, without DC-DC converter

Candida Infections in Severely Burned Patients: 1 Year Retrospective Study

Infections represent the most common complication occurring during the evolution of the severely burned patient, hence requiring closer study and targeted result analysis. The fungal infections are one of the most aggressive types of existing infections, their opportunistic character enabling them to cause invasive infections, ultimately leading to a higher morbidity and a higher rate of mortality. The present study focuses on the presence of Candida spp. in 19 out of a total of 70 patients admitted to the Critical Care Burn Unit in the Clinical Emergency Hospital Bucharest, between 01.01.2019-31.12.2019. No other fungal species, besides Candida spp., were identified in this patient lot. The aim of this study was to analyze the risk factors and the dynamics of the biological parameters of the patients presenting Candida spp. infections, in order to determine how these contribute to the prognostic and final outcome of these patients. We can conclude that a precise diagnostic and prompt treatment can make a significant difference in the outcome of severely burnt patients presenting with a fungal infection
