Published: April 2020

Driving with brady-tachy syndrome is one of the main causes of car accidents. In order to prevent drivers from brady-tachy driving, there is a strong demand for driver monitoring systems. Other than problems in driving attitudes and skills, road accidents are also caused by uncontrollable factors such as medical conditions and drowsiness. These factors can be avoided by having early detection. Therefore, the brady-tachy heart automotive so-called BT-Heartomotive device is developed. This BT-Heartomotive device can detect early signs of drowsiness and health problems by measuring the heart rate of the drivers during driving. The device also could use the data to send an alert to the passengers that they’re in precaution. The device shows a good accuracy in the detection of the heart rate level. The device comprised three main components; wristband, monitor and integrated mobile applications. Heart rate measurement can reveal a lot about the physical conditions of an individual. The BT-Heartomotive device is simple, easy to use and automated.

Published: April 2020

Forest biogeocenosis is a necessary environment for the normal existence of many species of wild animals, including birds. Recently, however, a gradual decrease in their numbers is observed in most forest areas of the Forest-Steppe zone. This indicator is one of the most important criteria for estimation of the general condition of this or that ecosystem. In this regard, specialists-zoologists, ornithologists, etc. pay great attention to the study of this issue (Koval' N.F. 1982). Currently, there is a quite extensive and often conflicting material regarding the number of birds. The most fundamental is the book by D. Lack, “The number of animals and its regulation in nature” (1957), which shows the influence of the food supply, the number of nesting places, “shelters”, and enemies on the reproductive ability, survival and general dynamics of the number of many bird species. Determining the breeding intensity of specific species populations of bird, we proposed to use the so-called productivity coefficient, which allows us to compare both the degree of biomass stability over the breeding period during a number of years and its geographical differences. The total number of birds on nesting can be different in various parts of the range under the influence of environmental conditions. The number of birds nesting on the ground and in the underwood has recently decreased significantly due to the large recreational burden of forest cenoses. Consideration of the dynamics of the number of daytime predatory birds and owls is of special attention. Their numbers have recently stabilized, although it continues to decline in some regions according to the available literary data. Ornithologists consider this mainly as a consequence of environmental pollution, killing of birds by humans, destruction of their habitats. The number of animal populations, for example, can vary significantly during the year or on average over the years. It is determined by the breeding rate and mortality of individuals. The breeding rate of birds is directly dependent on the size of egg laying, the success of eggs brooding and the percentage of flying out of viable young animals, which in total determines the success of breeding.

Published: April 2020

Objetivo: Comparar dos métodos de obtención de ADN usando muestras de sangre y de plumas de patos y gallinas. Metodología: Se utilizaron muestras de 13 aves: 10 patos (7 hembras, 2 macho; 1 sexo indefinido) y 3 pollos (2 hembras; 1 macho). Se extrajo ADN de sangre usando QIAamp ARN Mini Kit y para las muestras de plumas se utilizó el protocolo con proteinasa K. Se amplificó mediante PCR usando el protocolo y los primers P8 y P2. Resultados: Los resultados mostraron una mayor cantidad de ADN en las muestras de plumas y solo en estas muestras se pudo apreciar con claridad las bandas en la electroforesis. Por lo tanto se sugiere que el sexaje no solo de aves domésticas si no también silvestres que no cuentan con dimorfismo sexual puede realizarse fácilmente con plumas en lugar de muestras

Algorithm Selection in Multimodal Medical Image Registration
Authors: Elkeshreu Husein , Basir Otman
Published: April 2020

Over the past few decades, fast-growth has occurred in the area of medical image acquisition devices, and physicians now rely on the utilization of medical images for the diagnosis, treatment plans, and surgical guidance. Researchers have classified medical images according to two structures: anatomical and functional structures. Due to this classification, the data obtained from two or more images of the same object frequently provide complementary and more abundant information through a process known as multimodal medical model registration. Image registration is spatially mapping the coordinate system of the two images obtained from a different viewpoint and utilizing various sensors. Several automatic multimodal medical image registration algorithms have been introduced based on types of medical images and their applications to increase the reliability, robustness, and accuracy. Due to the diversity in imaging and the different demands for applications, there is no single registration algorithm that can do that. This paper introduces a novel method for developing a multimodal medical image registration system that can select the most accepted registration algorithm from a group of registration algorithms for a variety of input datasets. The method described here is based on a machine learning technique that selects the most promising candidate. Several experiments have been conducted, and the results reveal that the novel approach leads to considerably faster reliability, accuracy, and more robustness registration algorithm selection.

Published: April 2020

Background: Proper adjustment of arterial oxygen saturation (SaO2) during daily activities in interstitial lung disease (ILD) patients requiring long-term oxygen therapy (LTOT) is challenging. Given the multifactorial nature of the limited exercise tolerance in patients with ILDs, the isolated use of oxygen therapy may not be enough. As demonstrated previously in COPD patients, the use of a portable non-invasive ventilation (NIV) device combined with oxygen therapy may prevent the falling of oxygen saturation during exercise, due to an increased activation of respiratory muscles that could lead to an improvement of exercise tolerance. We sought to assess in patients diagnosed with ILD who are in need of oxygen therapy, the effect of associating a portable NIV to improve oxygen parameters and the distance covered during the 6 minutes walking test (6MWT).Methods: We conducted a prospective observational study in patients with ILDs. After a clinical characterization, we performed 6MWT in two different situations: using a portable oxygen concentrator with the regular flow used by the patient during their daily life activities and afterwards adding the additional support of a NIV. The oxygen saturation parameters were registered with a portable oximeter. Results: We included 16 patients with different ILDs who have oxygen therapy prescribed. The use of NIV associated with oxygen therapy in comparison with the use of oxygen therapy alone showed an increase of the average SaO2 [91% (88-93) vs 88% (86-90); p=0.0005] and a decrease in the percentage of time with oxygen saturation<90% (CT90): 36% (6-56) vs 58% (36-77); p<0.0001. There were no changes in the 6MWT distance: 307m (222-419) vs 316m (228-425); p=0.10Conclusions: In our study the use of a portable NIV system associated with LTOT during exercise showed benefitial effects, especially improvement of oxygen saturation.
Longer duration of breastfeeding is associated with lower BMI among individuals aged 8-49 months in Poland.
Authors: Pruszkowska-Przybylska Paulina , Żądzińska Elżbieta
Published: April 2020

Objectives: Breastfeeding in the first years of life seems to be an important factor affecting the shaping the body mass, and body mass/height proportion during first months of life, that importantly differentiates body mass and body proportion at the later stages of the human ontogenesis. The aim of this study was to evaluate if duration of breastfeeding affects BMI in later life.Material: In the analysis 470 children born in time, aged 8-49 months were included. The data came from the nurseries in Lodz (central Poland) where children' parents filed the questionnaires and was collected in years 1993-1997. In the analysis were included information about: duration of breastfeeding, parental educational level, birth body weight, birth body length. The BMI was standardized on sex and age of the children. The stepwise regression models were used to evaluate the hypothesis. The obtained residues for BMI were used to verify only breastfeeding impact using the regression analysis.Results: The regression model included parental education level and birth parameters were used to adjust BMI on them and revealed that low educated mothers had children with higher BMI (Beta=0.213; p<0.015). Additionally heavier newborns had higher BMI at the later stages of ontogenesis (Beta=0.207; p<0.001). There were made two regression analyses using BMI residues. The first one treated breastfeeding as categories, and revealed that children breastfed over 6 months vs. not breastfed or breastfed no longer than 1 month had lower BMI (Beta=-0.098; p<0.030). The second model treated duration of breastfeeding as a continuous variable, and showed that breastfeeding duration was inversely correlated with BMI residues (Beta=-0.092; p=0.042).Conclusions: Duration of breastfeeding differentiates the BMI among Polish children aged 8-49 months and seems to reduce BMI in further life.Trial registration: This study was conducted according to the guidelines laid down in the Declaration of Helsinki and all procedures involving research study participants were approved retrospectively by the Ethical Commission at the University of Lodz (NR21/KBBN- UŁ/I/2018). Written informed consent was obtained from all subjects' parents.

Background : Recently, it is well known the utility of both magnetic resonance imaging (MRI) and ultrasound (US) for rheumatoid arthritis (RA) in clinical practice. To investigate the favorable timing for monitoring of RA by MRI and US for predicting the radiographic progression during a treat-to-target (T2T) strategy. Methods : Symptomatic wrist and finger joints of 44 active RA patients (median disease duration 8.5 months), recruited in Nagasaki University Hospital from January 2010 to June 2017, were examined by MRI and US at baseline and then at 3-month (US) and 6-month intervals (MRI). The T2T strategy was used through 1 year. MRI was evaluated by RA MRI scoring (RAMRIS) and US by Outcomes Measures in Rheumatology Clinical Trial (OMERACT), respectively. Plain radiographs were assessed by the Genant-modified Sharp score for the symptomatic side. Radiographic progression was defined as an annual increase ≥0.75 at 1 year. Factors associated with radiographic progression were analyzed. The optimal use of MRI and US at each timepoint was considered. Results : Disease activity score (DAS) 28-ESR as well as inflammatory findings of MRI-proven bone marrow edema (BME) and US power-Doppler (PD) signal were reduced during treatment. A logistic regression model revealed that MRI-proven BME at baseline and 6 months and joint counts of PD grade ≥2 synovitis at 3 or 6 months are significantly associated with radiographic progression at 1 year. Conclusions : The combination of MRI and US at each timepoint may help predict radiographic progression in patients with early-stage RA during T2T strategies.

Published: April 2020

The atomic and electronic structures of reconstructions with (2 × 4), (4 × 2), c(4 × 4) and (4 × 3) symmetry on the (001) surface of GaSb and InSb semiconductors were studied by the projector augmented-wave method. It was shown that in the cation-rich limit the β2(2 × 4) reconstruction is stable on the GaSb(001) surface, whereas α2(2 × 4) has the lowest energy in the case of InSb. The c(4 × 4) reconstruction with three Sb dimers is found to be stable in the Sb-rich limit. Near stoichiometric composition the α(4 × 3) and β(4 × 3) structures are stable that is in agreement with experimental data. Electronic structure of the (4 × 3) reconstructions with lowest surface energy is discussed. A weak influence of chemical composition of cations on the surface state structure and their localization at the formation of (4 × 3) structures was revealed. The correlation between the surface energy of some (4 × 2) and (2 × 4) reconstructions and the difference in the atomic radii of anions and cations was established.
Doping-Dependent Nonlinear Electron Mobility in GaAs|In-=SUB=-x-=/SUB=-Ga-=SUB=-1-x-=/SUB=-As Coupled Quantum-Well Pseudo-Morphic MODFET Structure
Authors: Panda S.R. , Sahu A. , Das S. , Panda A.K. , Sahu T.
Published: April 2020

We analyze the asymmetric delta-doping dependence of nonlinear electron mobility μ of GaAs|InxGa1-xAs double quantum-well pseudo-morphic modulation doped field-effect transistor structure. We solve the Schrodinger and Poisson's equations self-consistently to obtain the sub-band energy levels and wave functions. We consider scatterings due to the ionized impurities (IMP), alloy disorder (AL), and interface roughness (IR) to calculate μ for a system having double sub-band occupancy, in which the inter-sub-band effects play an important role. Considering the doping concentrations in the barriers towards the substrate and surface sides as Nd1 and Nd2, respectively, we show that variation of Nd1 leads to a dip in μ near Nd1=Nd2, at which the resonance of the sub-band states occurs. A similar dip in μ as a function of Nd1 is also obtained at Nd1=Nd2 by keeping (Nd1+Nd2) unchanged. By increasing the central barrier width and well width, the dip in μ becomes sharp. We note that even though the overall μ is governed by the IMP- and AL-scatterings, the dip in μ is mostly affected through substantial variation of the sub-band mobilities due to IR-scattering near the resonance. Our results of nonlinear electron mobility near the resonance of sub-band states can be utilized for the performance analysis of GaAs|InGaAs pseudo-morphic quantum-well field-effect transistors. Keywords: asymmetric double quantum wells, GaAs|InxGa1-xAs structures, nonlinear electron mobility, pseudo-morphic HEMT structures, resonance of sub-band states.

Published: April 2020

The proposed solution relates to fluidics and can be used, for example, in the extraction of oil and gas, the collection and preparation of oil, gas and water, the extraction of methane from methane beds, oil refining. The technical result is to increase the efficiency of a liquid-gas ejector by ensuring its work in the field of rational concentrations and salt composition, in which the intensification of energy exchange between the working fluid and the ejected gas is achieved. The essence of the proposed solution: the method of operation of a liquid-gas ejector involves injecting a working fluid with a power pump into the ejector nozzle, pumping gas with an ejector, creating, dispersing and increasing the pressure of a gas-liquid mixture with an ejector using aqueous solutions of salts as a working fluid. The values of the concentration and composition of salts in the working fluid are maintained within the range of rational concentrations and composition of salts, in which increased values of the efficiency of the ejector are achieved. Salts are added to the weakly mineralized aqueous solutions, and the highly mineralized aqueous solutions are diluted with fresh water. As the working fluid, the formation and/or incidentally produced waters of oil, gas, gas condensate and methane-coal deposits, which are aqueous solutions of salts, are used if the composition and concentration of salts in the produced and/or incidentally produced waters are within the range of rational concentrations and composition of salts in which provides an increase in the efficiency of the ejector. The boundaries of the field of rational concentrations and salt composition are preliminarily determined by laboratory bench studies.
The state and the “rentier economy” in oil exporting countries
Authors: Ghukasyan Gurgen Levonovich
Published: April 2020

In the new foreign economic conditions that have arisen as a result of a significant deformation of the cyclical dynamics of the world oil market, the views on the model of the socalled “rentier state” and “rentier economy” that apply to oil exporting countries in Asia, Africa, Latin America, and also to the states of the post-Soviet space, including the Russian Federation, Kazakhstan, Azerbaijan and Turkmenistan, are of certain interest. For these states, in the face of declining oil export revenues, the question of changing the “rentier model” of development is relevant. At the same time, the recommendations of foreign authors are not acceptable in many aspects, but their analysis allows us to approach problems of overcoming the “raw nature” of the economy more comprehensively.

Francisco Suárez y la tradición del Contrato social
Authors: Schwartz Porzecanski Daniel
Published: April 2020

RESUMENesisten importantes discrepancias entre los intérpretes acerca de si Francisco Suárez fue un teórico del contrato social. En buena medida, este desacuerdo tiene que ver con la relación entre el consentimiento constitutivo (por el cual la comunidad política es creada) y la obligación política. De acuerdo con una interpretación de Suárez, el consentimiento constitutivo no crea obligación política; más bien tal obligación corresponde a la comunidad política en virtud de la clase de entidad que es(igual que las personas tienen sus derechos de autonoía por ser personas). Argumento en contra de esta interpretación de Suárez al proponer que los efectos del consentimiento constitutivo deberían ser comprendidos a la luz del tratamiento que ofrece Suárez de "actos operativos" como votos, promesas y juramentos. Defiendo que muchos de los pasajes de Suárez han sido incorrectamente interpretados como apoyo de una lectura organicista, cuando en realidad corresponden al planteamiento que hace de la causación moral.PALABRAS CLAVEFRANCISCO SUÁREZ, CONSENTIMIENTO, OBLIGACIÓN POLÍTICA, CONTRATO SOCIAL.ABSTRACTInterpretars disagree on whether Francisco Suárez was a social contract theorist. Much of this discrepancy turns on the relation between constitutive consent (that consent by wich the political community is created) and political obligation. According to one interpretation of Suárez, it is not constitutive consent that creates political obligation. Rather, such obligation belongs to the political community by virtue of he sort of being that it is (just as persons have self-rule rights by virtue of being persons, independently from their mode of production). I argue against this interpretation of Suárez by suggesting that the effects of constitutive consent should be understood in light of Suárez's treatment of "operative acts"such vows, promises, and oaths. i establish that many of Suárez's phrases incorrectly deemed as supportive of an organicist reading, bellong, in fact, to Suárez's treatment of moral causation KEYWORDSFRANCISCO SUÁREZ, CONSENT, POLITICAL OBLIGATION, SOCIAL CONTRACT

Este trabalho objetivou avaliar o potencial pedoclimático do Estado da Paraíba para a cultura agrícola do feijão caupi. Na obtenção dos mapas de potencial pedoclimático, as informações do potencial dos solos foram cruzadas com as obtidas da aptidão climática considerando três cenários pluviométricos: anos chuvosos, regulares e secos. O cruzamento das informações foi realizado por meio de técnicas de geoprocessamento utilizando o software SPRING e obtendo-se os mapas do potencial pedoclimático. O resultado das interpretações foi classificado em cinco classes de potencial pedoclimático: Muito Alto, Alto, Médio, Baixo e Muito Baixo. Os resultados demonstraram que áreas com potencial pedoclimático Baixo e Muito Baixo representam mais de 50% da área, o que sugere que outros usos da terra sejam desenvolvidos, como a pecuária extensiva com utilização de pastagem natural; As áreas com potencial pedoclimático Alto encontram-se principalmente na região do Litoral; Áreas de potencial Muito Baixo diminuem conforme o cenário se modifica do seco ao chuvoso, e as áreas de potencial Alto também diminuem conforme a mudança dos cenários; Devido à escala de trabalho 1:200.000 pequenas áreas não mapeadas podem apresentar potencial pedoclimático favorável ao desenvolvimento da cultura.    A B S T R A C T This study aimed to evaluate the potential of the soil and climate of Paraiba State for crop of cowpea.

A utilização do Sensoriamento Remoto para a avaliação do meio ambiente é cada vez mais aplicado em pesquisas. As imagens adquiridas pelos sensores acoplados aos satélites fornecem dados qualitativos e quantitativos do estado da vegetação através da aplicação dos índices de vegetação. Os índices são obtidos pela combinação matemáticas das reflectâncias dos alvos nas faixas espectrais, principalmente do vermelho e infravermelho próximo e podem ser afetados por diferentes fatores tais como reflectância, irradiancia e o brilho do solo. Um dos índices comumente utilizados, principalmente em áreas semiáridas, onde se tem influencia do brilho do solo, é o índice de vegetação ajustado ao solo (IVAS). Este índice introduz um fator de ajuste (L) ao índice de vegetação normalizada (IVDN) para minimizar os efeitos da presença do solo. Porém para cada região deve-se estudar e determinar os melhores parâmetros para o mesmo. Portanto este trabalho tem como objetivo apresentar uma revisão de literatura em relação ao índice de vegetação ajustado ao solo em diferentes biomas brasileiro e outras aplicações.   A B S T R A C T The use of remote sensing for environmental assessment is increasingly applied in research. The images acquired by the satellite sensors coupled to provide qualitative and quantitative information on the state of the vegetation by the application of vegetation indices. The indices are obtained by mathematical combination of the reflectance of the targets in the spectral bands, especially the red and near infrared and can be affected by different factors such as reflectance, irradiance and the brightness of the soil. One of the commonly used indices, especially in semi-arid areas where it has influence of soil brightness, is the vegetation index adjusted to the ground (UAI). This index introduces an adjustment factor (L) normalized vegetation index (NDVI) to minimize the effects of soil present. However, for each region should study and determine the best parameters for the same. Therefore this work aims to present a literature review regarding the vegetation index adjusted to the soil in different Brazilian biomes and other applications.

The purpose of this study is to analyze the teaching contents of a circle dealt with in an elementary mathematics textbook and to suggest an effective direction for teaching a circle. Through a longitudinal research, we analyze Korea's secondary curriculum up to 2015 revised curriculum. To a cross-sectional research, we compare and analyze recently published textbooks of Korea (1 type), Japan (4 types) and Singapore (2 types). Based on these findings, we suggest that math educators consider the following three points. First, it is necessary to raise the learning order of the center, radius, and diameter of the circle components. Second, it should be enhanced by the times when students use compass to draw circles. Lastly, in addition to the circles, the semi-circle and quarter-circle concepts need to be reflected in the curriculum.

Published: April 2020

As the global spread of novel coronavirus (SARS-CoV-2) escalates, the high demand for personal protective equipment (PPE) has created shortages of this equipment globally and prompted the need to ensure appropriate stewardship and develop strategies to conserve supply. Surgical masks have broad and commonplace applications as PPE, including in the care of suspected or confirmed COVID-19 patients, and for the care of the general patient population in areas where community spread of COVID-19 is of concern. Surgical mask rationing and conservation is therefore a priority to ensure adequate supply during a pandemic. Several methods have been considered to decontaminate and allow the reuse of single-use PPE, such as hydrogen peroxide vapour and ultraviolet germicidal irradiation, but to date this literature has not been comprehensively synthesized. The objective of this systematic review is to identify and synthesize data from published studies evaluating interventions used to decontaminate or treat surgical mask PPE for the purposes of reuse.

Innovation is a prominent phenomenon that enables a firm to gain a competitive advantage against its rivals. However, this does not mean that being innovative allow a firm to perform better. Although innovation has been investigated in the literature, the types of innovations still not understood well. As discussed, there are different types of innovations. Different kinds of innovation require different kinds of a business model and may have varying impacts on consumer product decisions. First, this study seeks to highlight the distinction between sustaining and disruptive innovations. Second, this study offers a conceptual framework for the antecedents of sustaining innovations. Theoretical and practical implications are discussed in the light of observations.

STUDYING BY THE METHOD OF THIN-LAYER CHROMATOGRAPHY OF POTENT AND POISON SUBSTANCES ON THE EXAMPLE OF CLOFELIN AND ATRAKURIA

Among crimes against the person, the most dangerous are crimes that are committed with the help of potent or poisonous drugs. Unfortunately, there is not yet a tendency to reduce the number of crimes committed, which always affects the state of social protection of citizens, increases tension in society, and undermines the authority of the state.

The disclosure of these crimes is fraught with considerable difficulties and a very large amount of work, which suggests that these crimes fall into the category of increased complexity.

There are a number of investigative and analytical tasks that may arise in any case involving the use of drugs, potent and poisonous drugs in order to facilitate the commission of a crime.

Crimes committed with the help of drugs, potent and poisonous substances include rape or other forms of sexual assault, robbery, robbery, extortion of money.

These crimes involve the use of drugs — these are crimes committed through the introduction into the human body of a substance with the intention to disrupt his normal behavior, perception or ability to make decisions without his consent after he voluntarily accepted a substance that deprives him of the ability to action.

Toxic substances when exposed to the body cause a sharp disruption of normal life, poisoning and death. These include, for example, snake venom, its derivatives, purified bee venom, clonidine (clonidine), etc.

Often passengers of railway trains become victims of robberies with the use of clonidine.

The psychoactive substances used in this type of crime can alter the victim’s state and orientation in reality, the ability to make decisions, as well as short-term memory loss. Such substances can make the victim vulnerable and unable to resist the attacker. In addition, they can be used in order to have a sedative effect on the victim in order to make it easier for the perpetrator to transport it.

Methods for the identification and quantification of clonidine chromatography in tonic layers can be used in pharmaceutical analysis of dosage forms of clonidine and muscle relaxants (atracuria), as well as in research in expert chemical laboratories.

In pharmaceutical analysis, qualitative color reactions are used to identify clonidine and atracuria. However, due to low sensitivity, nonspecificity and low availability of reagents, it is not suitable for the purposes of chemical-toxicological analysis.

Аморфты алюмосликат тасымалдағышына (ASA) және титан қос тотығына(рутил, TiO 2 ) отырғызылған родий және родий-алтын катализаторлары екi түрлi әдiспендайындалды: сiңiру және коллоидтық әдiс. Катализаторлар индуктивтi байланысқан плазмаоптикалық эмиссиялық спектрометр (ICP-OES), трансмиссиялық электронды микроскопия(ТЕМ) және рентгендiк дифракция (XRD) әдiстерiмен сипатталды. Дайындалғанкатализаторлардың белсендiлiгi мен селективтiлiгi бензолды және толуолды гидрлеуреакциясы арқылы сыналды. Гидрлеу 4 МПа қысым мен 80 0 С температурада жүргiзiлдi.Нәтижесiнде, сiңiру әдiсiмен дайындалған биметалды Rh-Au/ASA катализаторы бензолдыгидрлеу реакциясында, ал, коллоидтық әдiспен дайындалған осы катализатор толуолдыгидрлеу реакциясында жоғарырақ белсендiлiк көрсеттi. Бұл нәтиже басқа ароматтықосылыстар арасындағы бензолды селективтi гидрлейтiн катализатор алуға мүмкiндiк бередiдеп есептеймiз. Алтынның қосылуы родий катализаторының белсендiлiгiн айтарлықтайжоғарылата алмайтындығы, тиiмдi тасымалдағыш алюмосликат екендiгi, сондай-ақ, бензолмен толуолды гидрлеудiң өнiмдерi тек циклогексан және метил-циклогексан екенi анықталды.
