Fodboldens krav til kommunale stadionfaciliteter : et institutionelt perspektiv

Fodboldens krav til kommunale stadionfaciliteter – et institutionelt perspektiv (Danish pro-football’s demand for bigger stadiums: an institutional perspective) Although attendance figures in Danish football’s first tier are not in line with the Danish FA’s stadium requirements, the municipalities, which to a large degree fund the stadiums, comply with the stadium requirements and assist the clubs in obtaining their necessary league licenses. Taking on an institutional perspective, this study answers the question of why Danish municipalities follow these requirements and fund professional football stadiums that have a much bigger capacity than their regular attendance demands. The findings of the study can be summarized in three parts. First, coercive isomorphic processes are present within the homogenization process Danish stadiums are facing. As it is believed to be necessary to enhance facilities in order to keep Danish clubs competitive at the national and international level, the Danish FA, the Danish league, as well as the clubs, have been successful in realizing their demands for bigger stadiums. Second, it is also possible to discern mimetic isomorphic processes in the study. The competitive situation between municipalities, along with a conception of the clubs’ significance in the new experience economy, have contributed to the Danish municipalities’ compliance with the stadium requirements. Thirdly, although the municipalities have complied with the stadium requirements and funded the facilities, the analysis reveals a municipal opposition towards the requirements. However, the power balance between the clubs and municipalities seems to indicate that the clubs have the advantage, as the municipalities, despite their opposition, have conceded to making investments on the basis of the FA’s requirements.
Optimized Protocol for Chelex-based Extraction of DNA from Historical Skeletal Remains and Forensic Trace Samples

PCR-based analysis of skeletonized human remains is a common aspect in both forensic human identification as well as Ancient DNA research. In this, both areas not merely utilize very similar methodology, but also share the same problems regarding quantity and quality of recovered DNA and presence of inhibitory substances in samples from excavated remains. To enable amplification based analysis of the remains, development of optimized DNA extraction procedures is thus a critical factor in both areas.The method paper here presents an optimized protocol for DNA extraction from ancient skeletonized remains using Chelex-100, with improved effectively in yielding amplifiable extracts from sample material excavated after centuries in a soil environment, which consequently have high inhibitor content and overall limited DNA preservation. Further studies showed that the optimized protocol can likewise be utilized for extraction of DNA from common and trace Forensic sample material.
Head impact response-skull deformation and angular accelerations

The response of the head to impact was investigated using live anesthetized and post-mortem Rhesus monkeys and repressurized cadavers. The stationary test subject was struck by a guided moving impactor. The impactor striking surface was fitted with padding to vary the contact force-time characteristics. The experimental technique used a nine-accelerometer system rigidly mounted on the head to measure head motion, transducers placed at specific points below the skull to record epidural pressure, repressurization of both the vascular and cerebral spinal systems of the cadaver model, and high-speed cineradiography of selected test subjects. The results of the tests demonstrate the potential importance of skull deformation and angular acceleration on the injury produced in the live Rhesus and the damage produced in both the post-mortem Rhesus and the cadaver as a result of impact.

Radio frequency propagation differences through various transmissive materials.

The purpose of this research was to determine which of the commonly used wireless telecommunication site concealment materials has the least effect on signal potency. The tested materials were Tuff Span® fiberglass panels manufactured by Enduro Composite Systems, Lexan® XL-1 polycarbonate plastic manufactured by GE Corporation and Styrofoam polystyrene board manufactured by The Dow Chemical Company. Testing was conducted in a double electrically isolated copper mesh screen room at the University of North Texas Engineering Technology Building in Denton, Texas. Analysis of the data found no differences exist between the radio frequency transmissiveness of these products at broadband personal communication service frequencies. However, differences in the signal do exist with regards to the angle of incidence between the material and the transmitting antenna.
Flight Formation Control

This chapter presents an overview of the main issues relating to guidance and control of aircraft flying in a formation. Formation flight is a demanding task when performed manually, and it is a challenge for the flight control engineer, when performed in an automated fashion or by autonomous unmanned vehicles. The chapter focuses primarily on the investigation of possible formation structures to be used in an operational environment, with emphasis on optimization with respect to data information transfer among the elements (nodes) of the formation itself. The final objective is the capability of maintaining a formation in the presence of a failure of one of the vehicles/components, such as the loss of an aircraft, with a high degree of autonomy and possibly without intervention from ground and/or command operators. Although the emphasis is on unmanned aircraft, the principles could be extended to automated manned formation flight as well.

Automated quality assessment of stone aggregates based on laser imaging and a neural network

An automated quality assessment technique is proposed for rapidly detecting excessive size variations during the production of stone aggregates. The system uses a laser profiler to scan collections of aggregate particles and obtain three-dimensional data points on the particle surfaces. For computational efficiency, the resulting data are converted into digital images. Wavelet transforms are then applied to the images to extract features indicative of the material gradation. These wavelet-based features are used as inputs to an artificial neural network, which is trained to classify the aggregate sample. Taken together, these components form a neural network-based classification system that can determine whether or not an aggregate product is in compliance with a given specification. Verification tests show that this approach could potentially help to determine, in an accurate and fast (real-time) manner, when adjustments or repairs to the production equipment are needed.
Effect of a feedback system on the plasma flux in an accelerator with closed electron drift

The paper describes experiments involving the excitation and stabilization of electrostatic perturbations of the plasma in an accelerator with closed electron drift and an extended ion acceleration zone (ACED, also known as a linear Hall generator); a control system consisting of a sensor probe, a bandpass filter, a delay line, and amplifier, and a control electrode in the plasma is used. The control electrode controls the electron density in the plasma and results in stabilization or excitation of electrostatic perturbations in the channel depending on the signal delay in the control system. Certain features of the operation of the control system associated with the turbulent nature of the plasma perturbations have been discovered. (auth)
SPATIAL AND SEASONAL VARIATIONS IN HYDRAULIC CONDUCTIVITY IN RELATION TO FOUR DETERMINATION TECHNIQUES

Various techniques available to determine saturated hydraulic conductivity involve different methodologies and analytical models in their computations. In this study, these differences are quantified in relation to the variations in Ks estimates obtained by four techniques: Double Ring Infiltrometer (RI), Rainfall Simulator (RS), Guelph Permeameter (GP) and Guelph Infiltrometer (GI). Results show that the Ks values obtained with the GI and RS have a higher mean than values obtained by the RI and GP techniques. The RI and RS yield Ks estimates exhibiting lower variability as compared to those obtained with the GP and GI techniques. This study further revealed that the variations in Ks in the spatial and temporal domains can be expected to be as substantial as those due to the techniques themselves.
APOSTOLICA

: The purpose of this article is to highlight Pope Francis' concern and pastoral sensitivity in the face of the difficulties of many faithful to live the marriage ideal of the Gospel and how his merciful gaze towards those who live in so-called "irregular" situations led him to decree and establish a reform of the marriage nullity process, to make it simpler and more accessible. The analysis of the criteria, which guided the work of the reform, showed that all meet this pastoral concern. A joint reading of Amoris Laetitia and MIDI was carried out, because the two documents, dealing with the theme of the family and its difficulties, had at their origin the same pastoral concern and complement each other.
SPL36 encodes a receptor-like protein kinase precursor and regulates programmed cell death and defense responses in rice

The rice (Oryza sativa) spotted leaf 36 (spl36) mutant was identified from an ethyl methanesulfonate–mutagenized Japonica cultivar Yundao population and was previously shown to display a spontaneous cell death phenotype and enhanced resistance to rice bacterial pathogens. Through the analysis of the expression of related genes, we speculate that spl36 is involved in the disease response by up-regulating the expression of defense-related genes. The results of physiological and biochemical experiments indicated that more cell death occurred in the mutant spl36, and the growth and development of the plant were affected. We have isolated SPL36 via a map-based cloning strategy. A single base substitution was detected in spl36, which results in encoding amino acid changes in the SPL36 protein. The predicted SPL36 encodes a receptor-like protein kinase precursor that contains repeated leucine domains and may be involved in stress response of rice. In the salt treatment experiment, we found that the mutant spl36 showed sensitivity to salt. Therefore, SPL36 may negatively regulate salt stress-related responses.
Influence of rearfoot and forefoot midsole hardness on biomechanical and perception variables during heel-toe running

Abstract Purpose: Running shoe cushioning research has focused widely on rearfoot (RF) characteristics, whereas forefoot (FF) characteristics have been rather neglected. However, altered cushioning may affect running biomechanics and respective subjective perception at RF and FF. Thus, this research compared the effect of running shoes with different midsole hardnesses at RF and FF. Methods: Twenty-eight heel-toe runners were tested in five experimental shoe conditions that featured three segmented EVA midsoles (RF, midfoot (MF), FF). Three conditions had the same midsole hardness at RF and FF (soft (SS), medium (MM), hard (HH)). Two conditions had different RF and FF midsole hardness (soft-RF/hard-FF (SH), hard-RF/soft-FF (HS)). All midsoles featured the same MF segment of medium hardness. Vertical ground reaction forces and lower extremity kinematics during stance, subjective cushioning of the heel-toe transition and the overall comfort were quantified. Data were analysed using Kolmogorov-Smirnov tests, repeated measures ANOVA, Bonferroni post-hoc tests (p < 0.05), and effect size analyses (pη2). Results: The consistent midsole shoe conditions showed increased maximum loading rates of impact and propulsion peaks from SS to HH. Respective maximum loading rates of SH were similarly to SS, and respective maximum loading rates for HS were similar to HH. Subjectively, the consistent midsole conditions were rated according to their mechanical properties and softer shoes were preferred over harder shoes. In the varied midsole shoe conditions, SH was perceived similar to SS, whereas HS was perceived similar to MM. Conclusion: The examined biomechanical variables were influenced almost entirely by respective RF cushioning properties. The hard FF did not negatively affect cushioning perception as long as the RF was soft. Combining a soft FF with a hard RF improved inferior cushioning perception associated with shoes being hard at RF and FF.
Modeling of opto-electronics in complex photonic integrated circuits

This work addresses a versatile modeling of complex photonic integrated circuits (PICs) including optical and electrical sub-elements. We introduce a new family of electrical elements, together with a novel electronic-photonic co-design, that complements current capabilities of photonic circuit simulators. This is illustrated with the modeling of complex electric circuits contained in photonic devices. Simulations of the interaction between electrical and optical parts allow the analysis of unwanted effects such as reflections due to impedance mismatching, as well as the optimization of the PIC as a whole. We illustrate the functionalities of our approach through application examples. As a use case, we present a model of the electrical driver for a monolithically-integrated InP transmitter developed in frame of the European research project MIRTHE and the analysis of the driver and the EA-Modulator interplay.
Application of holography to evaluate the thermal deformation of printed circuit board connector due to thermal stress

The contact resistances of thermally stressed PCB connector contacts were measured. The holographic interferometry measuring system (HIMS) was applied to analyze the thermal deformation of the PCB connector due to current flow. As a result, we found some contact failure, and the HIMS was shown to be a very effective tool to measure the microscopic deformation pattern. In this paper, an experimental condition for application of thermal stress, the HIMS and the experimental results were introduced along with some suggestions for choosing high current contacts in a connector from the thermal deformation viewpoint.

An Object-oriented Formal Notation: Executable Specifications in Clay = Una notación formal orientada a objetos : especificaciones ejecutables con Clay

This thesis presents Clay, a stateless object-oriented formal notation. Clay is class-based, has a nominal type system that integrates algebraic types and inheritance, has equality, method overriding with Scandinavian semantics, dynamic binding, and a rather permissive overloading. The type system of Clay is used to reject illegal specifications, and also to help guide the translation schemes that define the Clay semantics and the generation of executable prototypes. Clay has a first-order semantics that gives an interpretation in first-order logic of the main object-oriented constructions: inheritance, defining classes by cases, overloading, dynamic binding and static equality. Furthermore, the use of the concrete syntax of an automatic theorem prover (Prover9/Mace4) has allowed mechanising both, the Clay's meta-theory and specifications. For example, some of the theorems about Clay in this thesis have been proved semi-automatically. The thesis presents also a compilation scheme of Clay specifications into Prolog programs. Code can be generated from implicit specifications, even recursive ones, something hard to find in other tools. My implementation takes advantage of various logic programming techniques in order to achieve reasonable efficiency: constraints, constructive negation, Lloyd-Topor transforms, incremental deepening search, etc. A Clay compiler is also contributed, a tool that goes beyond the mathematical presentation of the translations into first-order logic and the synthesis of logic programs. I have built a compiler that supports syntax analysis of modular Clay specifications, type checking, translation of Clay specifications into first-order theories in Prover9/Mace4, and synthesis of executable Prolog prototypes.
Steady-state modelling method for matrix-reactance frequency converter with boost topology

This paper presents a method intended for calculation of steady-state processes in AC/AC three-phase converters that are described by nonstationary periodical differential equations. The method is based on the extension of nonstationary differential equations and the use of Galerkin's method. The results of calculations are presented in the form of a double Fourier series. As an example, a three-phase matrix-reactance frequency converter (MRFC) with boost topology is considered and the results of computation are compared with a numerical method. where X(t) is a vector of state variables, and A(t) and B(t) are respectively a matrix and a vector of the converter. These equations can be solved using an approximation by the nume- rical-analytic method (3, 4). The search for solutions leads to converting nonstationary dif- ferential equations into stationary equations and their solutions. The method is based on the use the Lapunov transformation. Then, in order to calculate the convolutions of functions the Laplace transform is applied. This method can be used to find transient and steady-state
Broadband and compact ridge substrate-integrated waveguides

A novel class of substrate-integrated waveguides (SIWs) is presented, based on the concept of the classical ridge rectangular waveguide, which permits the design of broadband, compact and low-loss integrated components and interconnects. Two configurations are proposed. The former is the ridge SIW, where the structure is integrated in a dielectric substrate with top and bottom metal layers, and comprises two-sided rows of full-height metal cylinders and a central row of partial-height metal posts connected at their bottom by a metal strip. The latter is the ridge substrate-integrated slab waveguide; this structure presents a geometry similar to the ridge SIW, but includes additional air holes to further enhance the bandwidth. The design and experimental verification of two prototypes, covering the frequency band from 6.8 to 25 GHz and from 7.1 to 30.7 GHz, respectively, are also presented. The proposed structures exhibit a monomodal bandwidth three times broader than classical rectangular waveguides or SIWs, and their size is half of the SIW with the same cut-off frequency.
Transgender and Gender Non-Binary Healthcare Coverage in State Medicaid Programs: Recommendations for More Equitable Approaches

Transgender and gender non-binary (TGNB) individuals face discrimination in healthcare settings and barriers to healthcare access, resulting in health disparities. These inequities are compounded by the intersection of lower socioeconomic status and geography. To understand the differences in how states provide healthcare to TGNB individuals in poverty, we ask: What are state Medicaid programs offering TGNB residents, and how can coverage be more equitable across jurisdictions? To answer these questions, we examine medical services covered by 15 diverse Medicaid programs and compare them to the services recommended by the World Professional Association for Transgender Health (WPATH). Unsurprisingly, the analysis reveals inconsistent TGNB health coverage across states. While some states include coverage for TGNB-related care, some do not, and others place access to services in the hands of medical providers. These coverage disparities leave many TGNB Medicaid recipients across the U.S. without coverage for medically necessary services, prompting equity questions for both research and practice.
Lung Segmentation and Characterization in COVID-19 Patients for Assessing Pulmonary Thromboembolism: An Approach Based on Deep Learning and Radiomics

The COVID-19 pandemic is inevitably changing the world in a dramatic way, and the role of computed tomography (CT) scans can be pivotal for the prognosis of COVID-19 patients. Since the start of the pandemic, great care has been given to the relationship between interstitial pneumonia caused by the infection and the onset of thromboembolic phenomena. In this preliminary study, we collected n = 20 CT scans from the Polyclinic of Bari, all from patients positive with COVID-19, nine of which developed pulmonary thromboembolism (PTE). For eight CT scans, we obtained masks of the lesions caused by the infection, annotated by expert radiologists; whereas for the other four CT scans, we obtained masks of the lungs (including both healthy parenchyma and lesions). We developed a deep learning-based segmentation model that utilizes convolutional neural networks (CNNs) in order to accurately segment the lung and lesions. By considering the images from publicly available datasets, we also realized a training set composed of 32 CT scans and a validation set of 10 CT scans. The results obtained from the segmentation task are promising, allowing to reach a Dice coefficient higher than 97%, posing the basis for analysis concerning the assessment of PTE onset. We characterized the segmented region in order to individuate radiomic features that can be useful for the prognosis of PTE. Out of 919 extracted radiomic features, we found that 109 present different distributions according to the Mann–Whitney U test with corrected p-values less than 0.01. Lastly, nine uncorrelated features were retained that can be exploited to realize a prognostic signature.
The Law of Unintended Consequences in Soccer: Impact of Three-Point-A-Win Rule on Strategies and Outcomes

This paper analyzes whether the three-point rule in soccer brought more action to the game for a large sample of European championships in 1990-1997, revealing team-specic heterogeneity of responses caused by differences in team tactics in the period prior to the rule change. Teams that relied more heavily on tie-intensive tactics dramatically changed their behavior towards more attacking style in away games, considerably reducing probability of a tie. Interestingly, even though the three-point rule signicantly reduced proportion of ties, it did not bring more goals into the game because the increased rewards of scoring when the current score is tied were oset by increased incentives of defending the current score when one team led.
WELL-BEING AND LIFE SATISFACTION OF STUDENTS

Research into the quality of people's lives is a current issue addressed by a large number of researchers. Subjective measures indicate differences in real living conditions. The well-being of people is examined within the eudaimonic and hedonistic approach. As a part of the hedonistic approach, life satisfaction is largely examined. The hedonistic approach refers to social and psychological well-being. In this study, we investigated both approaches to examine the overall well-being of students. The participants' general satisfaction with life is very high. The survey of life satisfaction in certain domains shows that students are most satisfied in the domains of personal relationships, community and personal safety. The well-being of the participants is high. Participants exhibit high levels of emotional and psychological well-being, which are related to eudaimonia. Full-time students are more satisfied with life and have higher levels of subjective well-being than part-time students. No differences in eudaimonic well-being were found.
