Grounding systems for power supply facilities

This study aims to define some recommendations for choice of grounding system type for power supply facility. Operating modes of 0.4 kV networks approved by International Electrotechnical Commission (IEC) were considered and their advantages and disadvantages were identified. The comparison criteria were based on the conditions of human safety from electric shock in the breakdown of insulation on the body of electrical equipment, possibilities of expanding the network and uninterruptible power supply. The real application of the neutral modes and the possibility of installing protective devices were also taken into account. All the recommendations made is planned to apply for the modernization of the urban networks and the calculation of the earthing arrangement by using special software

Анализ колебательно-вращательного спектра высокого разрешения полос v4, v6, v7, v8, v10 молекулы C2H3D

Данное исследование посвящено анализу энергетической структуры взаимодействующих фундаментальных состояний (v10=1, A?), (v7=1, A??), (v8=1, A??), (v4=1, A??), (v6=1, A?) молекулы C2H3D, что с одной стороны позволяет моделировать положения спектральных линий данного изотополога, с другой - несет информацию о структурных параметрах и внутренней динамике молекулы. В конечном итоге найденные собственные значения и функции гамильтониана для исследованных состояний позволят рассчитать дипольные характеристики молекулы C2H3D, необходимые для определения компонентного состава и макропараметров газовых смесей: концентрации, температуры, давления.This study is devoted to the analysis of the energy structure of interacting fundamental states (v10 = 1, A?), (v7 = 1, A??), (v8 = 1, A??), (v4 = 1, A??), (v6 = 1, A?) of the C2H3D molecule, which, on the one hand, makes it possible to simulate the positions of the spectral lines of a given isotopologue, on the other hand, it carries information about the structural parameters and the internal dynamics of the molecule. Ultimately, the found eigenvalues ??and eigenfunctions of the Hamiltonian for the studied states will allow us to calculate the dipole characteristics of the C2H3D molecule, which are necessary for determining the component composition and macroparameters of gas mixtures: concentration, temperature, pressure

S1 guideline: Differential diagnosis of acute and chronic redness of the lower legs

Acute or chronic redness of the lower leg is a frequent reason for visits to clinics and practices. The differential diagnosis is often challenging. The aim of this guideline is to define criteria and procedures for the differential diagnosis of acute or chronic, unilateral or bilateral redness of the lower leg. Finding the correct diagnosis is essential for selecting an appropriate treatment and can help to reduce the inappropriate use of antibiotics. The guideline committee identified the most relevant differential diagnoses: 1. erysipelas, 2. stasis dermatitis, 3. hyperergic ictus reaction, 4. superficial and deep vein thrombosis, 5. gout, 6. chronic allergic contact dermatitis, and 7. acute toxic or allergic contact dermatitis. Algorithms/diagnostic pathways, each of which can be broken down into anamnesis, clinical examination, and diagnostics, have been developed for these seven diagnoses. In addition, the guideline group identified over 40 other relevant diagnoses and summarized their characteristics in a table to facilitate further differential diagnoses
