Az európai nyomozási határozat helye a büntető igazságügyi együttműködés uniós rendszerében – esetjogi elemzés
Authors: Szijártó István
Published: November 2021

Jelen tanulmány a dél-dunántúli régió bíróságain és ügyészségein végzett esetjogi kutatást mutatja be, amely a Somogy, Tolna és Baranya megye ügyészségei és bíróságai által kibocsátott, illetve azokhoz beérkező európai nyomozási határozatok (a továbbiakban rövidítve: ENYH) vizsgálja. A kutatás vizsgálódási szempontjai között szerepel, hogy milyen az a tipikus büntetőeljárás, amelyben ENYH kibocsátására kerül sor: milyen bűncselekmények miatt indul, milyen hosszú, milyen nemzetközi vonatkozásokkal rendelkezik és milyen módon fejeződik be. Emellett a kutatás célja, hogy a vizsgált ügyekben kibocsátott ENYH-k tartalmát is vizsgálja: adott ügyben hány ENYH-t bocsátanak ki, milyen eljárási cselekmények elvégzését rendelik el és azok milyen eljárási célokat szolgának, a kibocsátó hatóság milyen alaki követelményeket és eljárásokat határoz meg a végrehajtó hatóság számára és az ENYH útján külföldről beszerzett bizonyíték miképpen hasznosul a büntetőeljárásban. A kutatás célja az, hogy az előbbi szempontok alapján meghatározza azon esetek körét, amelyekben az ENYH alkalmazása ideális és ezzel együtt összevesse más uniós eljárásjogi eszközökkel, amelyek a tagállamok büntető igazságügyi együttműködésében szerepet kapnak.
Bird community monitoring at Wilson’s Creek National Battlefield, Missouri: Status report 2008–2020
Authors: Peitz David , Reibold Naomi
Published: November 2021

Breeding bird surveys were initiated on Wilson’s Creek National Monument, Missouri, in 2008 to assess temporal changes in the species composition and abundance of birds on the park and to improve our understanding of relationships between breeding birds and their habitat and the effects of management actions, such as invasive plant species control and tree thinning, on bird populations. Birds were sampled using point counts with 38 variable circular plots located on a systematic grid of 400 x 400-m cells (originating from a random start point). All birds seen or heard on a plot during a 5-min sampling period were recorded. In the 13 years since initiating our breeding bird survey, birds were surveyed on as many of the 38 variable circular plots as possible each year, resulting in 444 cumulative plot visits. Surveys have yielded records for 119 different species of birds. Ninety-eight of the species recorded are classified as permanent or summer residents to the area, 18 are classified as transients in the area, and 3 as winter residents to the area. Eight breeding species recorded are considered species of conservation concern for the Central Hardwoods Bird Conservation Region, the bird conservation region in which Wilson’s Creek National Battlefield is located. Of the 98 breeding species recorded, 12 species in grassland habitat and 15 in woodland habitat occurred in numbers large enough to calculate annual abundances with some degree of confidence. Trends in abundance were classified as uncertain for most species, which means that no significant increases or decreases occurred but it is not certain that trends were <5% per year. The Indigo Bunting (Passerina cyanea) population in grassland habitat was stable. The Eastern Towhee (Pipilo erythrophthalmus) and Eastern Wood-pewee (Contopus virens) populations in woodland habitat were in moderate decline. Comparing population trends on the park with regional trends for the Central Hardwoods Bird Conservation Region suggests that the bird community at Wilson’s Creek National Battlefield is faring similarly to that of the region as a whole. Stable diversity, richness, and evenness values suggest that the park’s habitat has remained consistent in its ability to meet the requirements of many of the park’s breeding bird species. Any decline in species richness could reflect habitat management practices, but it could also reflect the influences of larger-scale factors such as weather or climatic conditions on vegetation. Therefore, continued monitoring of birds and their habitats on Wilson’s Creek National Battlefield as management and weather and climatic conditions change is essential for park management.

The Demographics Behind the Courage to Tell for Survivors: Child Sexual Abuse Experiences in Kenya
Authors: Menja Wamuyu Eunice , Kathuri-Ogola Lucy , Muriithi Joan Kabaria , Swindle Taren
Published: November 2021

Child Sexual Abuse (CSA) is both a global and national social issue, as well as an epidemic in various societies. Non-disclosure of CSA only worsens and extends survivors’ suffering, and CSA’s long-term effects can be devastating. Several studies have been done in the field of CSA and its health implications but rarely have previous studies addressed child sexual abuse disclosure (CSAD). The current study aimed at examining child factors of CSAD at Thika Level 5 Hospital (TL5H) in Kiambu County, Kenya. The study is a case study using a phenomenology approach where the primary data was collected from the sexual abuse survivors and caregivers using a mixed-method analysis. Interviews were conducted with 30 CSA survivors, 25 girls, and 5 boys: 5-17 years. The study utilised the convergent QUAL (investigative open-ended questions and storytelling) design with a Quan component (structured survey) to identify CSA survivors’ experiences while receiving medical treatment and therapeutic intervention at TL5H. Descriptive and thematic approaches were applied to analyse qualitative data that revealed survivors’ lived experiences with CSA. Informed by Bronfenbrenner’s Socio-Ecological Model (SEM), saliency analysis was applied to code the recurring and important themes from the data in order to identify which child factors. Survivors gave detailed accounts of types of threats and manipulation applied by perpetrators to stop them from disclosing abuse. Survivors said disclosing or not disclosing helped them cope with abuse trauma. Quantitative results revealed that 58% of the survivors who completed the disclosure process aged between 9-13 years, 83.3% were female, and 70% had achieved a lower level of education.
Comparative Analysis of Motorcyclists’ Gaze Behavior in Different Road Environments
Authors: Lemonakis Panagiotis , Misokefalou Eleni , Eliou Nikolaos , Koroni Myrofora
Published: November 2021

While car drivers consist the vast majority of road users, motorcycle drivers are considered among the most vulnerable ones with significant participation in accidents. The present study investigates the role of elements that permanently exist in the road environment and affect motorcyclist’s behavior since their usefulness requires visual contact between them and the rider during a certain period of time. Therefore, on such an occasion the riders do not monitor the road ahead which is considered as a fundamental driving task and hence the visual search and scan is not directed to the frontal view. The main objective of this paper is to identify and evaluate certain aspects of motorcyclists’ behavior influenced by exterior factors, such as observation of vertical signage or advertisement signs, by using naturalistic data. Motorcyclist’s visual behavior is evaluated via a continuous recording of his gaze, which acts as the main indicator regarding the rider’s performance, with the use of special equipment under naturalistic riding conditions. The selection of a naturalistic method permits continuous data recording, producing real-time data. Thus, the results are reliable and valid to the maximum possible extent. This research is based on a medium-scale experimental procedure that took place in three different road sections in Western Greece. A number of 11 motorcyclists participated in the study. The present research may be used as a tool to improve road infrastructure and to identify attitudes that pose a risk to rider’s safety aiming to the creation of a safer road environment, which will lead to less fatal and serious accidents.

Authors: Jeyasubramanian Kadarkaraithangam , Paranibramma Nayagi Silambu Selvan , Hikku Gnanadhas Sobhin Osannal
Published: November 2021

Surface frictional drag developed by marine vessels utilizes a considerable percentage of fuel for propulsion. Superhydrophobic (SH) surface normally traps a layer of air at the interface and significantly reduces the surface frictional drag. Herein, the efficacy of the SH coating towards the surface drag reduction of the sailing boat is recognized by conducting a facile experiment where the bottom of the toy boat is coated with SH additives. AlNiCo nanoparticles and nickel stearate prepared by ball-milling and co-precipitation methods respectively are drop-casted layer by layer over the surface of the toy boat to impart SH. The fuel efficiency of the SH boat is improved by 51.49% substantiating the reduction in surface drag of the vessel. Further, the trapped air provides extra buoyancy force, enhancing the load-bearing capability of the SH boat by 5.77%.

Summary. At present, no scheme of approach to surgical treatment of patients with hip-lumbar syndrome (HLS) depending on the type of vertical posture and the type of bone formation and progression of coxarthrosis is developed. The decision of these questions, interesting from the scientific and practical point of view, is an actual task of modern orthopedics and defines features of preoperative planning of total hip arthroplasty (THA) in patients with HLS.

Objective: to determine the features of preoperative planning of total hip arthroplasty in patients with hip-lumbar syndrome.

Materials and Methods. The basis for the development of recommendations for preoperative planning of THA in patients with HLS was the data of retrospective analysis of medical histories of 138 patients who underwent hip arthroplasty in the Department of Orthopedics and Traumatology of Adults of SI “Institute of Traumatology and Orthopedics of NAMS of Ukraine”. The data of the clinical study of 506 patients with idiopathic, dysplastic and post-traumatic coxarthrosis conducted earlier were also taken into account, and the tactics of treatment in cementless hip arthroplasty was developed.

Results. It was determined that the vertical posture affects the progression of coxarthrosis and the nature of the lesion of the lumbar spine in patients with HLS. Patients with a certain hypolordotic posture and a rapid course of coxarthrosis are recommended to undergo primary decompression of the spinal roots and THA at the second stage. In other cases, the initial implementation of THA is recommended. Recommendations for the use of the type and method of fixation and coverage of the leg of the endoprosthesis depending on the type of bone formation in the HLS of the examined patients are developed.

Conclusions. Taking into account the features of preoperative planning of THA in patients with HLS will reduce the number of negative results and complications of this category of orthopedic patients.

Objectives To investigate the relationship between measures of adiposity and risk of incident kidney stone disease.

Patients and methods The UK Biobank is a prospective cohort study of ~500,000 participants whose height, weight, BMI, waist circumference, hip circumference, waist:hip ratio (WHR), total fat mass, fat-free mass, body-fat percentage and percentage truncal fat were measured at enrolment with linkage to medical records. ICD-10 and OPCS codes were used to identify individuals with a new diagnosis of nephrolithiasis from 2006-2010. Individuals with a history of kidney stones or incomplete data were excluded. Multivariate Cox-proportional hazard models were used to assess associations between anthropometric measures and incident kidney stones.

Results From the UK Biobank, 493,410 individuals were identified for inclusion; 3,466 developed a kidney stone during the study period. Increasing weight, BMI, waist and hip circumferences, WHR, and body and truncal fat were associated with increased risk of incident kidney stone disease. However, after adjustment for BMI, only waist circumference and WHR remained significantly associated with risk of nephrolithiasis. In overweight patients, high (men 94-102cm, women 80-88cm) waist circumference or WHR (men >0.9, women >0.85) conferred >40% increased risk of stone formation.

Conclusion This study indicates that android fat distribution is independently associated with increased risk of developing nephrolithiasis. Kidney stone disease is known to be associated with hypertension, cardiovascular disease, and diabetes, all of which are linked to android body shape. Our findings provide insight into anthropometric risk factors for stone disease, will facilitate identification of patients at greatest risk of stone recurrence, and will inform prevention strategies.

Published: November 2021

В работе рассматривается онтологический подход к интеграции знаний для поддержки междисциплинарных исследований в области энергетики и экологии с точки зрения оценки качества жизни, предполагающих интеграцию экологической и социальной составляющих. Экологическая составляющая определяется природно-климатическими условиями и состоянием элементов природной среды конкретной территории. Социальная - подразумевает обеспечение потребностей населения в электрической и тепловой энергии, необходимых для комфортного проживания. Для сопоставления положительного и отрицательного влияния функционирования объектов энергетики на население рассматриваются индикаторы качества жизни, как способ оценки этого влияния. Использование онтологического подхода обеспечивает наглядное представление и интеграцию знаний разных предметных областей. Представлены онтологии, детализирующие базовые понятия предметной области исследований антропогенного влияния объектов энергетики, качества жизни и отражающие их интеграцию в едином онтологическом пространстве знаний.

This paper examines an ontological approach to integrating knowledge to support interdisciplinary studies in energy and ecology in terms of quality of life assessment. These studies involve the integration of environmental and social components. The environmental component is determined by natural and climatic conditions and the state of elements of the natural environment of a particular territory. The social component implies meeting the demand of the population for electricity and heat, which are necessary for comfortable living. To compare the positive and negative impacts of the operation of energy facilities on the natural environment and the population, quality of life metrics are considered as a way to assess these impacts. We present ontologies detailing the basic concepts of the subject area of research on the anthropogenic impact of energy facilities and quality of life, and reflecting their integration into a single ontological space of knowledge. The use of the ontological approach provides a visual representation and integration of knowledge from different subject areas.

Published: November 2021

В статье исследуется зависимость стационарной температуры слоевого горения биомассы от скорости подачи и удельного расхода воздушного дутья. Для этого стационарное уравнение теплового баланса вместе с простейшим уравнением кинетики для химической реакции решается в широком диапазоне параметров. Для численного решения вводится ряд допущений (узкая зона реакции, преимущественный отвод теплоты путем лучистой теплопроводности, равновесный состав продуктов окисления). Результаты расчетов дают граничные значения расходных и стехиометрических параметров, при которых возможно устойчивое горение.

The article investigates the dependence of the stationary combustion temperature of layer combustion of biomass on the feed rate and specific consumption of air blast. For this, the stationary heat balance equation, together with the simplest kinetic equation for a chemical reaction, is solved over a wide range of parameters. For a numerical solution, a number of assumptions are introduced (a narrow reaction zone, preferential heat removal by radiant heat conduction, equilibrium composition of oxidation products). The calculation results give the boundary values of the consumption and stoichiometric parameters at which stable combustion is possible.

Published: November 2021

AbstractIn the current era of globalization, competition between countries is getting stronger and is determined by the quality of their human resources. One of the benchmarks is the Human Development and Literacy Index. The better the HDI number, the better the quality of the country's human resources, thus also literacy rate. However, the country of Indonesia, which is so vast and consists of thousands of islands, leaves a serious problem, namely the high inequality of HDI figures and the low numbers literacy of the people.This paper offers a discussion and a solution for increasing the development of Human Resources and Literacy with equilibrium theory in microeconomics, to overcome inequality which is currently a serious problem. This is of course in accordance with the constitutional mandate of "Social Justice for All Indonesian People" as a reference paper based on authoritative literature with social, economic and educational analysis.Key word : Human Development Index, Literacy, Equlibrium Theory

Published: November 2021

Abstract The aims of this study is to find out the way how to train students' metacognition in developing self-efficacy in the Mathematics subject matter. The writing of this article uses a library research approach. In general, metacognition relates to how to explore one's thoughts about thinking. Self-efficacy is a form of belief or belief related to one's own ability to organize, do something to achieve a goal, produce something, and also implement actions in order to achieve a certain form of skill.Based on the study of literature, training students' metacognition in developing self-efficacy in learning mathematics includes two dimensions of thinking, namely the awareness that a person has about his or her thinking (self-awareness of cognition) and a person's ability to use his/her consciousness to regulate his thinking process (self-regulation of cognition). By training to develop students' metacognitive awareness, it is hoped that students can arrange the information they face in solving problem-based questions so that they can develop students' mathematical self-efficacy.

Published: November 2021

Species of Tubakiaceae have often been reported as plant pathogens or endophytes, commonly isolated from a wide range of plant hosts. The isolated fungi were studied through a complete examination, based on multilocus phylogenies from combined datasets of ITS/LSU/rpb2 and ITS/tef1/tub2, in conjunction with morphological characteristics. Five strains isolated from Lithocarpus fohaiensis and Quercus palustris in China represented a new genus of Tubakiaceae, Obovoideisporodochium and three species, viz. Obovoideisporodochium lithocarpi sp. nov., Tubakia lushanensis sp. nov. and T. dryinoides.
Estimating credit default probabilities using stochastic optimisation
Authors: Joseph Dominic ,   Independent researcher, Kerala, India
Published: November 2021

Banks and financial institutions all over the world manage portfolios containing tens of thousands of customers. Not all customers are high credit-worthy, and many possess varying degrees of risk to the Bank or financial institutions that lend money to these customers. Hence assessment of default risk that is calibrated and reflective of actual credit risk is paramount in the field of credit risk management. This paper provides a detailed mathematical framework using the concepts of Binomial distribution and stochastic optimisation, in order to estimate the Probability of Default for credit ratings. The empirical results obtained from the study have been illustrated to have potential application value and perform better compared to other estimation models currently in practise.

The Einstein-Vlasov system in maximal areal coordinates---Local existence and continuation
Authors: Günther Sebastian , Rein Gerhard
Published: November 2021

We consider the spherically symmetric, asymptotically flat Einstein-Vlasov system in maximal areal coordinates. The latter coordinates have been used both in analytical and numerical investigations of the Einstein-Vlasov system [3,8,18,19], but neither a local existence theorem nor a suitable continuation criterion has so far been established for the corresponding nonlinear system of PDEs. We close this gap. Although the analysis follows lines similar to the corresponding result in Schwarzschild coordinates, essential new difficulties arise from to the much more complicated form which the field equations take, while at the same time it becomes easier to control the necessary, highest order derivatives of the solution. The latter observation may be useful in subsequent investigations.

Com base nos pressupostos teóricos da modernidade/colonialidade e nos estudos que problematizam o fenômeno da internacionalização da educação superior, busca-se, neste artigo, significar as experiências de técnicos administrativos da Universidade Federal de Santa Catarina (UFSC) que realizaram mobilidade de curta duração em universidades latino-americanas. Essa mobilidade ocorreu pelo Programa Escala Gestores y Administradores da Asociación de Universidades Grupo Montevideo (AUGM). Para isso, desenvolve-se um estudo de caso, com dados coletados por entrevistas com os oito participantes da UFSC nos anos de 2017 e 2018. A interpretação dos relatos aponta que suas experiências transcendem o discurso hegemônico e colonial da internacionalização. Constata-se a ênfase na história, na diversidade e no cotidiano dos sujeitos que integram as universidades públicas latino-americanas, que se distancia daquela orientada a suprir as demandas do mercado mundial capitalista.

Published: November 2021

The effect of high temperature annealing on microstructure evolution of Ni-24Fe-14Cr-8Mo alloy was investigated through Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and Rockwell Hardness Testing Machine. Three kinds of grain growth patterns were found at different annealing temperatures due to carbides precipitation and dissolution. After a combination of high temperature annealing and aging treatment, the hardness versus time curves performed a parabolic pattern. The highest hardness was achieved under 1070°C/60 minutes treatment, and the desirable annealing time should be 60 minutes to 90 minutes.

In this paper, the composites between polylactic acid (PLA) and eggshell powder (ESP) from the chicken shell were prepared by melt blending method in the internal mixer and then injection molded to produce the bio-composite specimen. The effect of the ESP concentration in the composites was investigated on the mechanical and thermal behaviors. The results indicated that the tensile strength and elongation decreased with increased ESP loading. Furthermore, the impact strength was not altered for PLA filled system with 10-30% of ESP. At the 10%wt of ESP in the PLA-composites was not significantly different of the onset (Tonset) and maximum degradation temperature (Td) from neat PLA but at higher ESP loading, Tonset and Td tend to decrease, therefore ESP could be able to accelerate degradation in the composites. The cold crystallization (Tcc) showed decreasing when the ESP was incorporate about 10-30 %wt. Otherwise, the incorporation of ESP affected on the declination of crystallinity in the PLA composites. The morphology, size and elements were examined using a scanning electron microscope (SEM) coupled with an energy dispersive X-ray system (EDX). It was indicated that agglomeration of ESP in the PLA matrix.

Thermoplastic starches and a nonwoven pineapple leaf sheet (NPALF) were prepared. Two types of flours were used to prepare thermoplastic starches (TPSs) which were Rice flour thermoplastic starch (RTPS) and Glutinous rice flour thermoplastic starch (GTPS). Two layers of thermoplastic starches and NPALF layer were sandwiched and pressed by a hot pressing machine at 150°C with 1500 psi for 15 min. All composites were investigated their densities and tensile properties. The density of all composite types had a lower density than each neat TPSs and types of rice flours did not affect their densities. The tensile property results confirmed NPALF could be used as a reinforcing agent both in GTPS and RTPS composites but their tensile improvement effectiveness in both systems are different. NPALF composite with RTPS did not affect the tensile strength but provided a slight improvement in modulus. Remarkably, NPALF composite using GTPS explored the great improvement performance both in strength and modulus which were increased up to 174% and 308% comparing with neat GTPS. SEM micrograph evidence clearly showed good wetting between GTPS and the reinforcement layer in the composite. This is resulting in the NPALF-GTPS composite showed a strong improvement in tensile properties.

Published: November 2021

This study investigated the stress and strain behavior caused in the forming process via simulation analysis using the finite element method, for suppressing punch shoulder and head plate thickness reduction die shoulder stress concentration by controlling the friction conditions. The following findings were obtained: The thickness of the blank head and punch shoulder decreased with the forming process. Due to the increase in the coefficient of friction with the punch side, the plate thickness reduction ratio decreases, and is the lowest when it is close to non-lubrication; Stress concentration occurs at the die shoulder with forming processing. With the increase in the friction coefficient value, forming limit parameter (FLP) increases slightly, but as it does not reach the limit value of 1, the forming process can be safely performed without mechanical damage; When the formability is comprehensively evaluated using the plate thickness reduction ratio and FLP, the friction coefficient μ = 0.4 to 0.5 is reasonable.

Published: November 2021

Endothelial cells (EC), which line the internal surface of blood vessels, play various essential roles in controlling vascular function. The mouse is an important animal model for the study of vascular biology and cardiovascular diseases. However, the isolation of primary EC from the murine aorta is challenging because they are readily contaminated by smooth muscle cells (SMC). A previous study developed a simple method to isolate murine EC from SMC. By taking advantage of the differential sedimentation rate between the two cells, the EC was selectively enriched with collagen-coated polystyrene surfaces. Our study further improved this method by introducing a biomimetic peptide REDV (Arg-Glu-Asp-Val), which may bind specifically to EC but not to SMC or fibroblasts. Firstly, REDV-gelatin conjugate was synthesized by using the amine-to-sulfhydryl crosslinker SMCC. REDV-gelatin coating was then prepared on polystyrene surfaces, and their affinities to EC and SMC were subsequently investigated. Fluorescence microscopy and flow cytometric analysis showed that EC adhesion to the gelatin coating was significantly promoted by REDV peptide conjugation. Moreover, cell migration assay and cell viability assay also showed that the conjugation of REDV does not affect EC migration, and this coating did not show cytotoxicity against EC. This gelatin-REDV coating provides a cost-effective and straightforward tool for isolating EC from SMC, which may facilitate in vitro investigations of EC from mice.
