Database of geomagnetic observations in Russian Arctic and its application for estimates of the space weather impact on technological systems
Authors: Kozyreva Olga , Pilipenko Vyacheslav , Dobrovolskiy Mikhail , Zaitsev Aleksandr , Marshalko Elena
Published: March 2022

An archive of digital 1-min data from Soviet/Russian Arctic magnetic stations has been created, starting from 1983 to the present. The archive includes data from stations deployed along the Arctic coast by various USSR/Russia institutes. All data are divided into daily files, converted into a standard IAGA2002 format, and provided with graphs for quick-look browsing. Some of the data are not included in the existing world data portals (SuperMAG, INTERMAGNET). We give examples of using the database for the Arctic: study of irregular disturbances and waves of the Pc5/Pi3 range exciting intense geomagnetically induced currents; distortion of the pipe-to-soil potential during magnetic storms; ground support for radar observations of the ionosphere. To assess the regions most susceptible to geomagnetic hazard, we calculated a map with normalized telluric fields for a uniform magnetic disturbance with a unit amplitude and periods 100–1000 s. This map shows that the geological structure significantly affects the magnitude of the geoelectric fields generated by magnetic disturbances. The database is made publicly available on the anonymous FTP site [ftp://door.gcras.ru/ftp_anonymous/ARCTICA_Rus].
The current state of the theory of Pc1 range ULF pulsations in magnetospheric plasma with heavy ions: A review
Authors: Mikhailova Olga , Klimushkin Dmitri , Mager Pavel
Published: March 2022

The review considers the current state of the theory of short-period ULF waves in plasma with admixture of heavy ions (ions whose mass significantly exceeds the mass of protons). The presence of heavy ions influences the spectrum and propagation characteristics of waves in Pc1 range. We examine elements of the theory of quasi-parallel and quasi-perpendicular short-period ULF waves. It is usually suggested that quasi-parallel ion-cyclotron waves have a left circular polarization. Quasi-perpendicular ion-ion hybrid waves have linear polarization and can be poloidal and toroidal. We discuss the theory of an equatorial resonator for Pc1 waves and determine its size from the density of heavy ions. In the radial direction, the waves can be locked in the vicinity of the plasmapause or in the region of a local minimum in the density of heavy ions. The equatorial resonator for arbitrary values of the wave vector components is considered. We note that ion-ion hybrid waves, in contrast to Alfvén waves, have a large parallel component of the magnetic field.
Daytime electron density at ionospheric F1-layer heights during geomagnetic storms (Irkutsk)
Authors: Kushnarenko Galina , Kuznetsova Galina , Yakovleva Olga
Published: March 2022

We have examined variations in electron density Ne at ionospheric F1-layer heights during geomagnetic storms at the Irkutsk ionospheric station (52° N, 104° E). We have selected geomagnetic storms of varying intensity as well as quiet days for each event for the winter and summer seasons of 2003. We have analyzed the electron density in the daytime during geomagnetic storms at 150–190 km heights. Different effects of geomagnetic storms on Ne in different seasons at these heights were found. There is a slight change in the electron density during summer geomagnetic storms. On the other hand, there is an interesting effect in winter indicating the summer-winter asymmetry of the Ne response to the geomagnetic storms at these heights in 2003: in winter there is a significant influence of disturbances on Ne at a height of 190 km and a smaller effect at lower heights.
Is the Central Register of Beneficial Owners a Reliable and Independent Source of Information? Different ways of Implementing the 4th and 5th AML Directives in Poland and Germany
Authors: Szulc Damian
Published: March 2022

The provisions of Directive 2015/849 (the 4th AML Directive) on the prevention of money laundering and terrorist financing required Member States to establish and maintain registers of beneficial owners, defined as natural persons who ultimately own or control the customer or the natural person on whose behalf a transaction or activity is carried out. The Directive sets out a general framework for the register, leaving Member States free to develop detailed solutions. Most Member States have already established relevant registers. Significant differences can be observed not only in the data held in the registers, but also in the way the registers are managed. In some countries no verification of the data held in the registers is carried out. This raises serious doubts as to whether such data can therefore be regarded as reliable and independent information. The author focuses in particular on comparing the solutions introduced in Polish and German law, making an attempt to formulate de lege lata postulates for improving the functioning of central registers of beneficial owners.Ostatnia dekada przyniosła postępującą cyfryzację i informatyzację życia społecznego i gospodarczego. Jest to trend nie tylko europejski, ale także ogólnoświatowy, a cyfryzacja i informatyzacja stanowią narzędzia w procesach globalizacji. Regulacje k.p.a., jak również p.p.s.a. z uwzględnieniem zmian przewidzianych w ustawie z dnia 18 listopada 2020 r. o doręczeniach elektronicznych odpowiadają ramowym standardom wynikającym z wytycznych Komitetu Ministrów Rady Europy w sprawie dowodów elektronicznych w postępowaniach cywilnych i administracyjnych z 30 stycznia 2019 r. Analiza prawa krajowego oraz wzajemne odesłania między aktami prawa krajowego, unijnego i międzynarodowego świadczą o dążeniu do ugruntowania wspólnych europejskich standardów. Dokument w postaci elektronicznej sukcesywnie wypierał będzie tradycyjne dokumenty, jednak nie można w tym kontekście zapominać o osobach informatycznie wykluczonych oraz o przyjętej zasadzie równorzędności tradycyjnej papierowej formy dokumentu i postaci elektronicznej. W kontekście wrastającej internacjonalizacji postępowań administracyjnych istotne jest zapewnienie wspólnych standardów informatycznych, aby ułatwić, a niekiedy wręcz umożliwić posługiwanie się dokumentem w postaci elektronicznej za granicą oraz ułatwić przekazywanie między państwami dokumentów elektronicznych z publicznych rejestrów.
Wdrożenie sieci 5G jako warunek rozwoju europejskich inteligentnych miast
Authors: Kawka Inga
Published: March 2022

One of the goals of Europe’s digital transformation is to improve the quality of life in European cities by making these cities smarter. This is possible due to the rapid technological development of the electronic communication sector and the introduction of 5G mobile networks and services. However, this requires huge investments in infrastructure and new technologies. The regulatory measures provided in the European Electronic Communications Code (no access obligations for wholesale-only operators and the co-investment mechanism) to promote infrastructure investments do not ensure the optimal regulatory environment for the deployment of 5G, which is a precondition for the emergence of smart cities.

Do zagrożeń zaliczyć można ryzyko awarii, pozyskiwanie danych wrażliwych oraz dylematy dotyczące prywatności i śledzenia poruszania się i przyzwyczajeń pasażerów.
Granice cyfrowej kontroli podatnika na przykładzie zmian uszczelniających w VAT
Authors: Grzybowski Tomasz
Published: March 2022

The article discusses the advantages and threats of the digital sealing of the VAT system. The study presents selected IT tools in the field of sealing the above-mentioned tax, such as SAF-T, STIR and the VAT white list. It leads to the consideration of their function and reservations related to collecting information about taxpayers on an unprecedented scale. The study points out that SAF-T and STIR seem to violate the fundamental rights of taxpayers by excessively interfering with the informational autonomy of business participants. Against this background, the VAT white list better balances the fiscal target, on the one hand, and the taxpayers’ guarantees, on the other.
Learning in Temporary Teams: The Varying Effects of Partner Exposure by Team Member Role
Authors: Kim Song-Hee , Song Hummy , Valentine Melissa A.
Published: March 2022

In many workplaces, temporary teams convene to coordinate complex work, despite team members having not worked together before. Most related research has found consistent performance benefits when members of temporary teams work together multiple times (team familiarity). Recent work in this area broke new conceptual ground by instead exploring the learning and performance benefits that team members gain by being exposed to many new partners (partner exposure). In contrast to that new work that examined partner exposure between team members who are peers, in this paper, we extend this research by developing and testing theory about the performance effects of partner exposure for team members whose roles are differentiated by authority and skill. We use visit-level data from a hospital emergency department and leverage the ad hoc assignment of attendings, nurses, and residents to teams and the round-robin assignment of patients to these teams as our identification strategy. We find a negative performance effect of both nurses’ and resident trainees’ partner exposure to more attendings and of attendings’ and nurses’ exposure to more residents. In contrast, both attendings and residents experience a positive impact on performance from working with more nurses. The respective effects of residents working with more attendings and with more nurses is attenuated on patient cases with more structured workflows. Our results suggest that interactions with team members in decision-executing roles, as opposed to decision-initiating roles, is an important but often unrecognized part of disciplinary training and team learning.

Tibial tuberosity-trochlear groove distance: does it measure up?
Authors: Krishnan Harry , Eldridge Jonathan D. , Clark Damian , Metcalfe Andrew J. , Stevens Jarrad M. , Mandalia Vipul
Published: March 2022

Recognized anatomic variations that lead to patella instability include patella alta and trochlea dysplasia. Lateralization of the extensor mechanism relative to the trochlea is often considered to be a contributing factor; however, controversy remains as to the degree this contributes to instability and how this should be measured. As the tibial tuberosity-trochlear groove (TT-TG) is one of most common imaging measurements to assess lateralization of the extensor mechanism, it is important to understand its strengths and weaknesses. Care needs to be taken while interpreting the TT-TG value as it is affected by many factors. Medializing tibial tubercle osteotomy is sometimes used to correct the TT-TG, but may not truly address the underlying anatomical problem. This review set out to determine whether the TT-TG distance sufficiently summarizes the pathoanatomy, and if this assists with planning of surgery in patellar instability.

Published: March 2022

Background: Throughout medical school students are exposed to a variety of fields within medicine, but structured leadership and teaching opportunities are limited. There is a need for more training to prepare students of all backgrounds to be future leaders in all healthcare realms, especially critical care medicine, in order to address the lack of diversity seen in leadership positions. Methods: Implemented entirely by students with faculty guidance, the Kern model was applied to develop a student-run longitudinal Designated Emphasis in Healthcare Leadership. This program was implemented at a medical school leading the nation in creating opportunities for diverse and underrepresented groups in medicine. Students are involved in structured leadership lectures, projects, and mentorship, and there is an emphasis on learning by doing. A survey was sent out to all present and past student participants to assess its acceptability and effectiveness. Results: A post-participation survey found that a total of 96% of participants identified themselves as healthcare leaders, felt confident leading a team, and felt comfortable working with a diverse team. Further, 96% of participants agreed or strongly agreed they would recommend the program to other medical students. Qualitative feedback revealed that participants felt they learned how to “apply leadership skills to the healthcare setting” and were provided an “environment to grow and practice vital leadership skills that will help [them] be effective clinicians.” Conclusions: Our initial research shows that introducing a longitudinal leadership program into Medical Education may allow participants to start developing personal and professional leadership qualities. The program is well-received by the students and preliminary data shows that there may be increase in leadership capabilities when participating in this program. Such a program can enable future healthcare providers to become leaders in their own fields, so that they can hone interpersonal communication skills, bridge the gap of representation in leadership positions, and lead teams effectively.
Using individual preferences and BWM with entropy measures to modify the Global Entrepreneurship Index
Authors: Chen Caixiang , Zhu An
Published: March 2022

The Global Entrepreneurship and Development Institute (GEDI) annually releases the Global Entrepreneurship Index (GEI) to measure the quality and dynamics of entrepreneurship ecosystems at a national and regional level. The published Global Entrepreneurship Index takes the arithmetic mean value of the individual level of entrepreneurial attitudes, abilities and aspirations. In this paper, we alternatively consider all individual preferences among these three sub-indices, the performance results of which are obtained by means of a sophisticated manner. The entropy values of these performance results are derived to reduce the information redundancy. The best-worst method (BWM) is employed to determine the common weights with respect to each individual preference. An empirical study using the data of GEI-2019 is performed to indicate the validness of our methodology.
Changes of cross-sectional morphology and channel capacity during an extreme flood event, lower Tisza and Maros rivers, Hungary
Authors: Sipos György , Fiala Károly
Published: March 2022

When examining the characteristics of individual floods Hungarian researchers primarily investigate hydrological and hydraulic processes, whilst the relation between flood events and morphological changes of the river-bed are widely ignored. The present research quantifies the morphological changes of two cross-sections of the lowland reaches of the River Tisza and its tributary, the River Maros, during a high magni-tude flood which occurred in spring 2000. During the flood several key morphological cross-section variables (mean depth, channel bed eleva-tion, maximum depth, cross-sectional area and channel capacity) were monitored. Relationships between these data and daily river stage height series of the flood and specific stream power were determined. Results suggest that the identified morphological changes highly affect the channel capacity of the two cross-sections during the flood event. The channel capacity changes (9-10%) were almost identical for both study sites. However, different morphological processes characterised the two cross-sections. We found that morphological parameters de-pend not only on the actual stream power, but the available amount of sediment for transport, the rate of stage and stream power change.

Discorrer acerca da criação da Universidade Federal de Ouro Preto (1969) e analisar o papel da Escola de Farmácia nesse processo é o intuito deste artigo. Através de pesquisa bibliográfica e de ampla investigação documental realizada no Arquivo Histórico da instituição corrobora-se que o curso farmacêutico de Ouro Preto além de ser pioneiro e de se manter perene na cidade de Ouro Preto desde o século XIX, também exerceu papel primordial na criação da Universidade Federal de Ouro Preto (UFOP), sendo um centro de referência e expansão educacional na região antes mesmo do seu processo de federalização e mesmo após a sua incorporação à UFOP.
Repercusiones de las guerras civiles en Colombia en el sistema de instrucción pública, siglo XIX
Authors: Pico Roger Pita
Published: March 2022

El propósito de este artículo consiste en examinar el impacto de las guerras civiles decimonónicas en las escuelas y colegios de Colombia a través de la destrucción de las aulas y la ocupación de las tropas, la represión política y el reclutamiento militar de alumnos y profesores y, asimismo, profundizar en el análisis de las repercusiones en la interrupción de las labores escolares y en el ritmo de aprendizaje, además de las marcadas fluctuaciones en los niveles de cobertura. La intención es llenar un vacío historiográfico por cuanto los escasos estudios sobre la educación en Colombia en el siglo XIX se han concentrado en demostrar los avances de este sector en tiempos de paz. Más que describir los estragos de la guerra, este trabajo ha dejado constancia también de los esfuerzos y sacrificios por mantener activos los servicios educativos aun en medio del ambiente de agitación política y de la confrontación militar. En ese sentido, cabe resaltar la iniciativa de ayuda de algunos profesores, el aporte de algunos empleados públicos, la movilización del clero a escala parroquial y los esfuerzos conjuntos de las diferentes instancias del gobierno nacional, provincial y local con miras a asegurar algunos recursos en medio del estado de devastación generalizada.
O reposicionamento político do Barão de Abiahy nos debates educacionais do fim do Império e início da República
Authors: Costa Suenya do Nascimento , Costa Jean Carlo de Carvalho
Published: March 2022

Este artigo demonstra como Silvino Elvídio Carneiro da Cunha – o barão do Abiahy, figura atuante da elite política na Paraíba e representante do partido conservador, permaneceu monarquista até as vésperas da proclamação republicana, aderindo ao novo regime estabelecido e ajustando seu discurso envolvendo as reformas educacionais para continuar em condições de controle político. Com a República, alguns sujeitos do final do século XIX reposicionaram suas ideias sobre elementos centrais da instrução. Estas discussões, como parte das concorrências políticas, encontravam-se, sobretudo, nos jornais e nos relatórios presidenciais. Percebe-se uma concepção adesista e liberal em vários momentos como: defesa da instrução para os ingênuos, ideário do Ensino Livre e criação de aulas noturnas para o público adulto trabalhador. Assim, constata-se o caráter adesista na atuação do barão de Abiahy, que representava a redefinição do jogo político em período caracterizado pela coexistência de posicionamentos diante do ordenamento educacional, político e social.

ANTIBACTERIAL POTENCY OF CELL FREE SUPERNATANT PRODUCED BY LACTIC ACID BACTERIA ISOLATED FROM INDONESIAN FERMENTED FISH PRODUCTS AGAINST HISTAMINE-PRODUCING BACTERIA
Authors: Putra Masagus Muhammad Prima , Al-Hammam Muhammad Yaafi , Ahsan Giffarri , Chandra Klara Kharisma Bunga , Puspita Indun Dewi
Published: March 2022

The toxicity caused by high histamine content produced by histamine-producing bacteria (HPB) during the fermentation of scombridae fish group based fermented fish products is still a problem that requires a solution. This study aims to explore the potential of secondary metabolites in the form of cell free supernatant (CFS) produced by lactic acid bacteria (LAB) as antibacterial agents against HPB. The LAB was isolated from the fermented fishery products named bekasan, cincalok and fish sauce using MRS-Agar and fermented on MRS-broth for 48 hours. CFS was collected by centrifugation at 15,000 x g for 15 minutes, followed by heating at 100oC for 3 minutes and pH neutralization with 0.1N NaOH. Antimicrobial activity of CFS then tested on HFB namely Morganella morganii TK7, Citrobacter freundii CK1, and Klebsiella sp. CK13.2 (collection of the Laboratory of Fisheries Product Quality and Safety, Department of Fisheries UGM) using the macrodilution method. Isolation of LAB from all three products successfully isolated 34 isolates. The results of the antibacterial activity showed that 4 isolates namely GMCN 1.12, GMBK 2.6, GMBK 2.7, dan GMKI 2.1 were able to inhibit HFB growth more than 70%. The highest activity was shown by GMBK 2.7 which inhibits 98% against Morganella morganii TK7, 99% against Citrobacter freundii CK1, and 84% against Klebsiella sp. CK13.2. The antimicrobial activity was reduced after proteolytic enzymes were added suggesting that the bioactive compound came from peptide-based substances like bacteriocin.
Implicit/Explicit, BEM/FEM Coupled Scheme for Acoustic Waves with the Wave Equation in the Second Order Formulation
Authors: Banjai Lehel
Published: March 2022

Acoustic scattering of waves by bounded inhomogeneities in an unbounded homogeneous domain is considered.
A symmetric coupled system of time-domain boundary integral equations and the second order formulation of the wave equation is described.
A fully discrete system consists of spatial discretization by boundary and finite element methods (BEM/FEM), leapfrog time-stepping in the interior, and convolution quadrature for the boundary integral equations.
Convolution quadrature is based on BDF2, trapezoidal rule, or a newly introduced truncated trapezoidal rule that has some favourable properties for both the implementation and quality of approximate solution.
We give a stability and convergence analysis under a CFL condition of the fully discrete system.
The theoretical results are illustrated by numerical experiments in two dimensions.

Inpainting of regular textures using ridge functions
Authors: Kazantsev Ivan G. , Turebekov Rauan Z. , Sultanov Murat A.
Published: March 2022

In this paper, we propose a
method for inpainting regular textures composed of oriented patterns
and completion of images distorted by
long stripes.
We have developed a model fit to describe a regular texture as a sum of a few ridge functions. The ridge functions are known in tomography as a result of a back-projection operator applied to projections, or samples of the Radon transform.
A computational scheme for the singular value decomposition of a regular texture into the sum of informative ridge functions is presented.
The numerical experiments on various images demonstrate the efficiency of the techniques proposed.
Serum spexin levels are not associated with size at birth but are associated with metabolic syndrome components in prepubertal children born at term
Authors: Öztürk Önsal Fatma Duygu , Elitok Gizem Kara , Bülbül Ali , Uçar Ahmet
Published: March 2022

Background

Babies born small for gestational age (SGA) are at risk of obesity and metabolic syndrome (MetS). Spexin (SPX) is a novel peptide implicated in food intake and obesity. Spexin levels are lower in obese subjects. This study investigated the potential association of SPX and some obesity related peptides such as leptin and active ghrelin with size at birth and MetS components in prepubertal children born term and either SGA or appropriate for GA (AGA). Secondary aim was to identify whether any of the investigated peptides were associated with MetS components.

Methods

We conducted a cross-sectional study of 37 consecutive (median age: 5.6 y) SGA- and 50 (median age: 5.9 y) AGA-born children. Clinical evaluations were performed using standard methods. Several biochemical variables (SPX, total leptin, and active ghrelin levels) were analyzed. Age-dependent cut-off values were used to define MetS components, including excess adiposity, hypertension, insulin resistance, and dyslipidemia. The associations between the assessed clinical and laboratory variables and MetS components were investigated.

Results

Children born SGA had higher frequencies of MetS components than AGA-born peers (p < 0.01). None of the investigated peptides were different between children born SGA and AGA after correcting for body mass index (p > 0.05 for all). Serum SPX levels were lower in children with at least one metS component than those without MetS components (p = 0.018).

Conclusions

Size at birth had no association with serum SPX. Serum SPX levels are decreased in prepubertal children with MetS components.

The relevance of this study is conditioned by the high degree of importance of creating the latest modifications of the polymer–bitumen binder for the manufacture of high-quality asphalt concrete, for its subsequent use in the construction of motorways and concrete pavements of airfields. In this context, the purpose of the study is to obtain new, scientifically substantiated technological solutions for the development and practical application of effective nanomodified polymer-bitumen binders (PBBs) that can improve the operational characteristics and duration of practical use of asphalt. The study results clearly demonstrate the fact that carbon nanotubes (CNTs) are a stabiliser and an ageing inhibitor of polymer–bitumen binders (PBBs), while contributing to a decrease in the intensity of its operational destruction over time by more than 10 times relative to the compositions of PBB with structuring additives, which is essential in the preparation and practical use of asphalt concrete for the construction of motorways and airfields. The results obtained are of significant importance for developers of modern technologies for manufacturing asphalt concrete for road construction, and road maintenance workers who professionally solve the problems of road maintenance, applying the latest practical developments in the field of road construction and repair in their activities.

Authors: Rai Devendra , Sinha Shishir
Published: March 2022

The review focuses on the recent development in anode materials and their synthesis approach, focusing on their compatibility for treating actual industrial wastewater, improving selectivity, electrocatalytic activity, stability at higher concentration, and thereby reducing the mineralization cost for organic pollutant degradation. The advancement in sol–gel technique, including the Pechini method, is discussed in the first section. A separate discussion related to the selection of the electrodeposition method and its deciding parameters is also included. Furthermore, the effect of using advanced heating approaches, including microwave and laser deposition synthesis, is also discussed. Next, a separate discussion is provided on using different types of anode materials and their effect on active •OH radical generation, activity, and electrode stability in direct and indirect oxidation and future aspects. The effect of using different synthesis approaches, additives, and doping is discussed separately for each anode. Graphene, carbon nanotubes (CNTs), and metal doping enhance the number of active sites, electrochemical activity, and mineralization current efficiency (MCE) of the anode. While, microwave or laser heating approaches were proved to be an effective, cheaper, and fast alternative to conventional heating. The electrodeposition and nonaqueous solvent synthesis were convenient and environment-friendly techniques for conductive metallic and polymeric film deposition.
Urban-economic geographies beyond production: Nairobi’s sociotechnical system and the challenge of generative urbanization
Authors: Murphy James T.
Published: March 2022

Urban-regional economies are developing in highly variegated, uneven ways globally. In economic geography, studies of urban-regional development emphasize the prospects for innovative, globally-competitive industrial sectors to emerge and enhance a city-region’s exchange value in global markets. This focus reflects a productivist bias that may fail to address issues related to the use-value of, or living conditions associated with urban transitions. Such concerns are particularly significant in the Global South where urbanization has often not led to socioeconomic transformations that benefit the majority of urban residents. To examine the relationships between a city’s exchange and use value, this paper argues for a sociotechnical systems approach that conceptualizes cities as constituted by interdependent or coupled regimes related to production, consumption, and infrastructure that stabilize urban-regional economies and determine development pathways. The framework is deployed empirically to examine the case of Nairobi, Kenya – a rapidly growing urban-regional economy characterized by high rates of inward foreign direct investment, principally in speculative real estate ventures in the consumption regime. Domestic manufacturing industries (the production regime) are stagnating, struggling to compete against imports, and failing to generate widespread formal employment and raise tax revenues for the infrastructure regime. The net result is a city characterized by fragmented or splintered regimes that create highly uneven, exclusionary development outcomes. These dynamics and findings are analyzed in relation to a similar study of Dar es Salaam, Tanzania in order to demonstrate the comparative potential of this conceptual approach. The paper concludes with a call for economic geographers to better account for the use-value of urban-regional economies such that development concerns beyond production become more central to our analyses.

Published: March 2022

Gruppierungs- und Reihenfolgeprobleme der Fertigung zählen zu den zentralen Fragestellungen der operativen Produktionsplanung. Gruppierung bezeichnet dabei die zu treffenden Entscheidungen über Größe und zeitliche Lage von Fertigungsaufträgen (Losen), während der Reihenfolgeaspekt die Belegung der Anlagen zum Gegenstand hat. Im vorliegenden Beitrag wird ein neues konzeptionelles Modell vorgestellt, mit dessen Hilfe Gruppierungs- und Reihenfolgeentscheidungen bei reihenfolgeabhängigen Rüstvorgängen simultan getroffen werden können. Schließlich wird diskutiert, wie sich das vorgeschlagene Gruppierungs- und Reihenfolgemodell verallgemeinern läßt.

Wissensbasiertes Datenmodell für Konstruktion und Arbeitsplanung
Authors: Tönshoff Hans Kurt , Zahn Guido
Published: March 2022

Obwohl in der Konstruktion oftmals moderne CAD-Systeme eingesetzt werden, ist die digitale Übernahme geometrischer oder gar technologischer Daten aus der Konstruktion in der Praxis kaum zu finden. Eine kürzlich durchgeführte Umfrage zeigt deutlich, daß sich darüber hinaus häufig erhebliche Probleme durch nicht fertigungsgerecht gestaltete Werkstücke ergeben. Es wurde daher ein auf Technischen Elementen basierendes Datenmodell entwickelt, das die Abbildung und den Austausch aller im Bereich von Konstruktion und Arbeitsplanung relevanten Daten zuläßt sowie das zur Planung und Fertigung eines beschriebenen Werkstücks notwendige fertigungstechnische Wissen enthält.

Lewis, MH, Siedler, MR, Lamadrid, P, Ford, S, Smith, T, SanFilippo, G, Waddell, B, Trexler, ET, Buckner, S, and Campbell, BI. Sex differences may exist for performance fatigue but not recovery after single-joint upper-body and lower-body resistance exercise. J Strength Cond Res 36(6): 1498–1505, 2022—This study evaluated sex differences in performance recovery and fatigue during dynamic exercise. Twenty-eight resistance-trained males (n = 16) and females (n = 12) completed a repeated-measures, randomized, parallel-groups design. The protocol consisted of a baseline assessment, a recovery period (4, 24, or 48 hours), and a postrecovery assessment. The assessments were identical consisting of 4 sets of 10 repetition maximum (10RM) bicep curls and 4 sets of 10RM leg extensions to failure. Recovery was quantified as the number of total repetitions completed in the postrecovery bout. Fatigue was quantified as the number of repetitions completed set to set within the session. For analysis, we set the level of significance at p ≤ 0.05. No sex differences in performance recovery were observed across any of the investigated time periods for either exercise modality. Regarding fatigue, significant effects were observed for set (p < 0.001) and sex (p = 0.031) for bicep curls. Repetitions dropped in later sets, and females generally completed a greater number of repetitions than males (8.8 ± 0.5 vs. 7.2 ± 0.5). For leg extension, a significant sex × set interaction was observed (p = 0.003), but post hoc tests revealed these sex differences as marginal. Our results suggest that in dynamic bicep curls and leg extensions, other factors unrelated to sex may be more impactful on performance recovery. To optimize an athlete's desired adaptations, it may be more important to consider other variables unrelated to sex such as volume, perceived exertion, and training history when formulating training prescriptions for single-joint exercises.

Cross, JA, Higgins, AW, Dziuk, CC, Harris, GF, and Raasch, WG. Relationships among shoulder rotational strength, range of motion, pitching kinetics, and pitch velocity in collegiate baseball pitchers. J Strength Cond Res XX(X): 000–000, 2022—Throwing shoulder injuries are the most common type of injury experienced by baseball pitchers. Weakness in the shoulder musculature and insufficient throwing arm range of motion are both risk factors for developing a shoulder injury. The goal of this study was to determine correlations among shoulder rotational strength, range of motion, pitching kinetics, and pitch velocity in collegiate pitchers. Thirteen uninjured male college pitchers were evaluated. Clinical measures included shoulder internal and external rotation range of motion, peak isokinetic internal and external rotator strength, and peak isometric internal and external rotator strength. Three-dimensional biomechanics were assessed as subjects threw from an indoor pitching mound to a strike zone net at regulation distance. Pearson's correlations were used to assess the associations among the clinical measures and throwing metrics. Five significant correlations were found between peak shoulder compressive force and strength, and 4 significant correlations were found between pitching velocity and strength (p < 0.05). No significant correlations were found between range of motion and pitching kinetics or velocity. Our results suggest that as shoulder rotational strength increases, the peak shoulder compressive force and pitch velocity both increase. Knowledge of relationships between strength metrics and pitching biomechanics may allow for improved strength training routines with the goal of increasing velocity without increasing injury risk.
