Published: March 2021

Aim: to determine the effectiveness of using a step-platform to improve the technique of performing elements with the manifestation of static and dynamic strength of female students engaged in sports aerobics.
Material and methods. The study involved 20 female students of Kharkov higher educational institutions, who were engaged in sports aerobics in sports improvement groups. Research methods. The questionnaire was carried out among aerobics coaches in order to reveal their attitude to the use of a step-platform in the process of studying and improving the technique of elements of dynamic and static strength. The pedagogical experiment was carried out in 2 stages and lasted for 6 months from October 2019 to March 2020. At the first stage, the existing level of development of the physical abilities of the subjects was revealed, in particular, flexibility (bending forward from a sitting position), power abilities (flexion, extension of the arms in a lying position, hanging on bent arms, lifting the body in a sitting position in 1 min.), Speed ( run 60 m), agility (shuttle run 4x9 m), endurance (run 1000 m) and techniques for performing basic elements of dynamic and static force, which were taken as control ones. The assessment of each of the control elements was carried out on a 10 point scale. The athlete received the highest score for the impeccable performance of the element, for each gross error she lost 3 points, the average 2, and the small 1 point, loss of balance and fall during the execution of the element did not give the subjects a single point.
Results. A significant increase in flexibility, strength and endurance, as well as marks for the technique of performing elements of dynamic and static strength, was revealed. Significant relationships were revealed between the scores for the STRADDLE LATERAL PUSH UP and HINGE PUSH UP technique and the indicators of flexion and extension of the arms in the supine position and weight on bent arms. Significant correlations were also revealed between the scores by STRADDLE SUPPORT 1/1 TURN and LIFTED STATIC WENSON SUPPORT and the indicators of forward bending of the trunk and lifting of the trunk to the sitting position in 1 min.
Conclusions. Provided sets of exercises using a step platform. The exercises are aimed at developing physical qualities for performing elements with the manifestation of dynamic and static strength. The exercises are also aimed at learning and improving the technique of these elements in various conditions. Their effectiveness in physical and technical preparation of girl students for the fulfillment of elements with the manifestation of dynamic and static strength in sports aerobics has been experimentally proved.

Authors: Sreedharan Sadhishaan , Gray Steven , Bruscino-Raiola Frank
Published: March 2021

Background: Traditional socket-based prostheses are an important rehabilitation tool in lower limb amputation, however, patients often experience skin-related problems, pain, stump volume fluctuations and poor suspension. Osseointegration offers a suitable alternative by providing direct skeletal attachment for limb prosthesis. This study aims to review the complications following osseointegration for lower limb amputation, with attention to mechanical abutment failure. Method: A retrospective chart review was undertaken of all patients who underwent transfemoral osseointegration between January 2000 and June 2019 through the osseointegration and targeted muscle reinnervation surgical and rehabilitation program at The Alfred in Victoria, Australia. Ethics approval was obtained through The Alfred’s ethics committee (414/16). In 2016 this program was redesigned and in 2017 the osseointegration implant system was modified. Patients underwent a two-stage surgical procedure followed by a rehabilitation protocol that gradually increased their activity. Results: A total of 19 limbs were osseointegrated in 18 patients during the study period. Two patients had their implant removed due to failure of osseointegration. The most common complication was a mechanical abutment failure, occurring 46 times in 11 patients. Patients who suffered an abutment failure reported higher levels of postoperative activity. Soft-tissue infections occurred in five patients: three superficial skin infections and two collections. There were no mechanical abutment failures noted in the updated program.Conclusion: Osseointegration is a good option for patients who may have difficulties with traditional socket prosthesis. However, complications such as abutment fracture can occur, and appropriate patient selection and counselling are required

WIID Companion (March 2021): global income distribution
Authors: Gradín Carlos
Published: March 2021

This document is part of a series of technical notes describing the compilation of a new companion database that complements the UNU-WIDER World Income Inequality Database. It aims at facilitating the analysis of inequality as well as progress in achieving the global goal of reducing inequality within and across countries. This new dataset includes an annual series reporting the income distribution at the percentile level for all citizens in the world, regardless of where they live, from 1950 to the present. The global distribution is displayed along with the country-level information used to produce it. The dataset also includes estimates of various global absolute and relative inequality measures, and the income share of key population groups. All estimates are further disaggregated by the contribution of inequalities within and between countries, as well as by each country’s geographical region and income group. While previous technical notes described the selection of country income distribution series and the integration and standardization process to overcome the heterogeneity in original welfare concepts and other methods, I here describe all the necessary additional steps and assumptions made to construct the new global dataset.

La proliferación de las redes sociales y la facilidad que otorgan a sus usuarios para compartir información alienta a compartir lo que ocurre a su alrededor. Las redes sociales ayudan a conocer diferentes acontecimientos, y al estar conscientes de ellos, nos ayuda a tomar decisiones con mayor certeza. Por ejemplo, acerca del tránsito vehicular, el utilizar las redes sociales nos ayuda a saber cuándo están presentes manifestaciones o cuando ha ocurrido un accidente, esta información nos ayuda a eludir un congestionamiento vial desafortunado. Aprovechando la generación de contenido en Twitter y tomando como caso de estudio la Ciudad de México, se recolectó información de usuarios dedicados a publicar eventos viales. Por tanto, se propone una metodología para la geocodificación de textos cortos y un método de aprendizaje automático basado en Máquinas de Soporte Vectorial, con el cual se obtiene un modelo capaz de realizar un análisis espacio temporal de eventos viales. Como caso de estudio se consideró a la Ciudad de México.

Os mapas como operadores na gênese da cidade espraiada. Desconstrução e semiose cartográfica na análise das plantas da cidade de São Paulo entre 1877 e 1930
Authors: Kuvasney Eliane
Published: March 2021

El presente trabajo trata de la cartografía producida sobre la ciudad de São Paulo entre 1877 y 1930 y de cómo esa cartografía interfirió en la forma de como la ciudad fue vista y construida en el período. Se parte de la configuración del área urbano metropolitano y de su extensión, de forma que las cuestiones que guiaron la investigación giraban en torno a la lógica de la expansión de la ciudad: si fue pensada para tener esa característica o se fue construyendo según el mercado inmobiliario, o si la expansión fue causa o consecuencia de las desigualdades socio-espaciales, y finalmente, si los mapas interfieren en la extensión de la ciudad. A través del enfoque geohistórico y de la metodología de análisis de mapas de la Nueva Historia de la Cartografía, que constituye en la deconstrucción de los objetos cartográficos por medio de la comprensión del contexto en que fueron elaborados, se desarrolló el presente trabajo. La primera parte del trabajo, presenta la contextualización del período a partir de la bibliografía existente, además de los análisis de las actas y anales del Ayuntamiento de São Paulo, y de los informes de intendentes y alcaldes, con el fin de comprender el período y la forma en que el patrimonio municipal —las tierras pertenecientes al municipio— fueron apropiadas por el mercado inmobiliario en la construcción de la ciudad, al mismo tiempo que no se obedeció el código de situación que, desde 1875 exigía que el municipio fuera mapeado. Con el objetivo de analizar si los mapas tendrían capacidad de actuar “con desempeño” en el espacio geográfico, si los mismos actuaron como operadores en la construcción de la ciudad, se analizó la car-tografía del período con el propósito de comprender los fenómenos de la autorreferencia y de la iconización.

Published: March 2021

In this work numerical simulation results are shown for the steady state response of linear mechanical oscillating systems and the numerical errors that can be present when some numerical algorithms are used to perform the simulations. For some numerical parameters, the mechanical oscillating system with or without damping response, does not converge to the expected steady state response; this discrepancy is not easily detected when the performance of the system is on the range of high excitation frequencies, due that for of high excitation frequencies the amplitude in the steady state response reaches very small values. We perform the time response of the system using conventionally numerical methods included in the common programming platforms, and the result is that using the same algorithm in different platforms the error is the same; selecting other numeric algorithm the result in satisfactory. Non linear forced mechanical vibration systems; behave like linear systems for some frequency range, then is very useful to obtain the right or correct responses in the steady state response for the linear system, this is fundamental for forward studies, the right analysis is based on the selected numeric algorithm.

Authors: Ozmen Alper , Saritas Tufan
Published: March 2021

Mint ismeretes, az export kedvező gazdasági jelenség, amelynek növelésére törekszenek minden országban. A tanulmány a közszféra intézményi tényezőinek exportra gyakorolt hatását vizsgálja az OECD 36 országában, a 2002-2018 közötti időszakra vonatkozóan. A vizsgálat során négy különböző modellt hoztak létre, és az exportot minden modellben függő változóként határozták meg. Az első modell szerint negatív összefüggés van a korrupciókontroll és az export között. A második modellben szintén negatív összefüggést találtak a szabályozás minősége és az export között. A harmadik modellben megfigyelhető, hogy pozitív kapcsolat van a politikai stabilitás és az export között. A negyedik - a jogállamiság exportra gyakorolt hatásait vizsgáló - modellben nem volt statisztikailag szignifikáns kapcsolat a változók között.

Published: March 2021

An experiment was conducted during September 2019 - January 2020 to investigate the effects of cultivars and different weed management practices on yield attributes, yield, nutrient uptake and soil micro-flora in dry direct-seeded rice (DDSR). Experiment was laid out in split plot design replicated thrice. The treatment combination consisted of three levels of cultivars in main plot (ADT 46, CO 52 and Improved white ponni) and five levels of weed management practices in the sub plots (application of pendimethalin @ 1 kg a.i ha-1 as pre-emergence herbicide at 3 days after sowing (DAS), bispyribac-sodium @ 0.02 kg a.i ha-1 as post-emergence herbicide at 20 DAS, sequential application of pendimethalin @ 1 kg a.i ha-1 followed by (fb) bispyribac-sodium @ 0.02 kg a.i ha-1, hand weeding twice at 20 and 40 DAS and weedy check). Both the cultivars and weed management practices influenced the growth, nutrient uptake, soil microbial population and yield of the DDSR. However, the interaction did not influence any of the parameters significantly. Rice cultivar ADT 46 proved to be superior with respect to nutrient uptake and yield. Whereas, among weed management practices, the highest nutrient uptake and yield were obtained with sequential application of pendimethalin @ 1 kg a.i ha-1 fb bispyribac-sodium @ 0.02 kg a.i ha-1.

Authors: Pathak Dalibha , Kalita Umesh Ch.
Published: March 2021

Sixteen genotypes of rice (including one check) were evaluated on 18 quantitative traits during sali (August), 2018 in a randomized block design with three replications at Instruction cum Research Farm, Department of Plant Breeding and Genetics, Assam Agricultural University, Jorhat to study the nature and magnitude of variability, heritability and genetic advance under delayed sown condition. The analysis of variance for 18 quantitative traits revealed the presence of significant differences for grain yield and its component characters. The highest genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) was observed for chaffs per panicle followed by grains per panicle, spikelet sterility (%), spikelets per panicle, grain yield (kg/ha). A high heritability coupled with high genetic advance was observed for plant height (cm), spikelets per panicle, spikelet sterility (%), chaffs per panicle, grains per panicle, grain yield (g/hill), grain yield (kg/ha), biological yield (kg/ha), straw weight (kg/ha) and harvest index (%) indicating that selection might be effective for improvement of these characters under delayed sown condition with low input. From the findings of this investigation, one genotype viz., Gandhari emerged as the outstanding genotype which yielded 4170 kg/ha and could be directly used for cultivation in delayed sown situation with low inputs. Some other promising genotypes that yielded higher than the check Manoharsali under delayed sown condition were JR 29, JR 16, Basundhara and JR 60 and could be utilized as potential parental material in the hybridization programmes designed to develop suitable rice varieties for delayed sown situation.

Published: March 2021

Spiders are one of the most fascinating and diverse invertebrates and also potential bio-control agents in agro-ecosystems. Field surveys were carried out at Sundernagar, Jogindernagar, Nurpur and Palampur areas of Himachal Pradesh by two methods namely visual count and sweep net to assess seasonal abundance and diversity of spider, in the rice ecosystems during kharif, 2015 and 2016. It was found that the population trend was well represented by visual count method as compared to sweep net method. Maximum numbers of spiders were recorded from Palampur area followed by Sundernagar, Jogindernagar and Nurpur. Eleven families viz., Oxyopidae, Tetragnathidae, Salticidae, Lycosidae, Pisauridae, Araneidae, Theridiidae, Clubionidae, Sparassidae, Thomisidae and Pholcidae were recorded from the fields with majority belonging to Araneidae and Tetragnathidae. The pre-dominant spider genus from all the locations were Tetragnatha and Neoscona while Araneus pseudosturmii and Runcinia ghorpadei Tikader were confined only to Nurpur and Sundernagar, respectively. A. pseudosturmii and Micropholcus fauroti Simon seem to be the first records from India while R. ghorpadei to be the hitherto unknown male morph.

SYSTEMIC APPROACH TO DETERMINING THE SAFETY OF SUSTAINABLE DEVELOPMENT OF AIR TRANSPORT: INDICATORS, LEVEL, THREATS
Authors: BUGAYKO Dmytro , KHARAZISHVILI Yuri , LIASHENKO Viachelsav , KWILINSKI Aleksy
Published: March 2021

The article is dedicated to methods of integrating the safety of air transport in the mechanism of interaction between sustainable development goals and strategic management of sustanable development security through managerial, functional, and informational links between subsytems of sustainable development and different hierarchal levels of safety. This determines the place and role of aviation safety in ensuring fundamental national interests, i.e. sustainable development of national economy. The multifactor hierarchal model detailing the level of safety of air transport was developed in accordance with the system approach in the context of sustainable development and combines the economic and technological, social, and environmental components. It is proposed to consider a total of 7 components and 29 indicators that include shadow economy aspects, without which the current conditions cannot be estimated accurately. The boundaries of safe existence have been defined for all indicators using Student’s t-test. The conducted modelling has determined the current values of all indicators and the safety level of air transport as a whole. Identification has been carried out in accordance with the latest assessment methodology, including the multiplicative integral indices, modified method of normalization and formalized determination of dynamic weights. The list of threats and their severity have been determined using two criteria. Distance from the point of sustainable development, i.e. average value of the «homeostatic plateau», was used to identify the list and importance of threats, while the severity of threats was calculated using elasticity coefficients. The calculations show that the safety of air transport depends foremost on the social component, as well as economic and technological development of aviation.

The paper presents the methods for fire identification using low-resolution space images obtained from Terra Modis and NOAA satellites. There are lots of algorithms to identify potentially "fire pixels" (PF). They are based on the assessment of temperature in spectral ranges from 3.5–4 to 10.5–11.5 microns. One of the problematic aspects in the Fire Detection Method using low-resolution space images is "Cloud and Water Masking". To identify "fire pixels", it is important to exclude from the analysis fragments of images that are covered with clouds and occupied by water objects. Identification of pixels in which one or more fires are actively burning at the time of passing over the Earth is the basis of the algorithm for detecting potentially "fire pixels". The algorithm requires a significant increase in radiation in the range of 4 micrometers, as well as on the observed radiation in the range of 11 micrometers. The algorithm investigates each pixel in a scene that is assigned one of the following classes as a result: lack of data, cloud, water, potentially fire or uncertain. The pixels that lack actual data are immediately classified as "missing data (NULL)" and excluded from further consideration. Cloud and water pixels, defined by the cloud masking technique and water objects, belong to cloud and water classes, respectively. The fire detection algorithm investigates only those pixels of the Earth's surface that are classified as potentially fire or uncertain. The method was implemented using the Visual Programming Tool PowerBuilder in the data processing system of Erdas Imaging. As a result of the use of the identification method, fires in the Chornobyl exclusion zone, steppe fires and fires at gas wells were detected. Using the method of satellite fire identification is essential for the prompt detection of fires for remote forests or steppes that are poorly controlled by ground monitoring methods.

The article considers the methods of calculating radio signal power. The main factors influencing the distribution and their connection with the error in the calculations of the indicators' peak values are analyzed. The regularities of signal propagation and the correlation between the distance from the radio signal source and the ratio of noise to useful information are determined. These patterns allow us to develop a model of artificial intelligence, which improves the prediction of results compared to existing calculation methods. The obtained results present the efficiency of the offered method.
GENERATING FIRE-PROOF CURTAINS BY EXPLOSION-PRODUCTION OF WATER AEROSOL AS AN ELEMENT OF FIRE-SAFETY ENGINEERING
Authors: Śmigielski Grzegorz
Published: March 2021

Parameters of a fire-quenching system based on explosive water-aerosol production and spreading are presented. Such a system with correctly tailored amounts of the water and the explosive material produces water-aerosol with high fire-quenching efficiency due to the small radii of the droplets and at the same time secures that shock-wave pressures are safe for the human body at distances exceeding 30 m from the explosion axis.
METODA OKREŚLANIA RZECZYWISTEJ WARTOŚCI CIŚNIENIA W PRÓŻNIOWEJ KOMORZE GASZENIOWEJ SN
Authors: Lech Michał , Kostyła Damian
Published: March 2021

W artykule opisano autorski sposób pozwalający na określenie rzeczywistej wartości ciśnienia w próżniowej komorze rozłącznikowej SN podczas wysokonapięciowych badań laboratoryjnych. Konieczność opracowania metody tego typu wynikła z braku możliwości pomiaru ciśnienia bezpośrednio w komorze próżniowej w trakcie badań. Istniało bowiem ryzyko uszkodzenia próżniomierza w wyniku przeskoku elektrycznego. Proponowana metoda polega na pomiarze w warunkach beznapięciowych różnicy ciśnienia pomiędzy zestawem pomp próżniowych, a prototypem komory próżniowej wykonanym dla potrzeb realizacji tej metody. Dzięki temu znając wartość ciśnienia przy pompach oraz mając wyznaczone charakterystyki skalowania układu, w trakcie badań wysokonapięciowych możliwe będzie określenie rzeczywistego ciśnienia wewnątrz badanej rozłącznikowej komory gaszeniowej SN. Przeprowadzono pomiary spadku ciśnienia w kanale pompowym dla powietrza oraz trzech gazów elektroujemnych: helu, argonu oraz neonu, wykorzystywanych w badaniach przez autorów niniejszego artykułu.
