Published: January 2021

PurposeKnee sleeves have become widely popular in the exercise realm, especially for knee support during back squats. Knee sleeves are successful in providing frontal plane knee support during functional tasks, but have not been investigated in back squats. Knee wraps, a somewhat similar elastic material, provide elastic energy that increases weight lifted during back squats. Thus, it is possible the thick neoprene knee sleeves could prove advantageous for back squats. The purpose of this study was to examine the effects of knee sleeves on weight lifted, knee biomechanics, and muscle activations during back squats.MethodsFifteen resistance trained men and women performed 1-repetition maximum (1-RM) squats to full depth and 80% 1-RM to full and parallel depths during two separate randomized sessions: with/without knee sleeves. Three-dimensional motion capture, force platforms, and electromyography recorded knee biomechanics and activations of the rectus femoris, vastus medialis, biceps femoris long head, and gluteus maximus during all squats.ResultsMaximal weight lifted did not improve when using knee sleeves. Frontal plane knee biomechanics did not differ for 1-RM or submaximal squats to either depth between conditions. Knee external rotation moments during descent were larger with sleeves during submaximal squats. Reduced integrated ascent phase gluteus maximus activations occurred during both 1-RM and submaximal squats with knee sleeves.ConclusionsThe results of this study show that wearing knee sleeves does not provide additive effects to weight lifted and do not appear to alter frontal plane mechanics during weighted back squats.

PurposeOne factor affecting successful performance in beach handball is the efficiency of shootings. As only few studies evaluated gender-related differences in shooting performance, the aim of this study was to analyse variations of shooting efficiency between males (M) and females (F) during beach handball matches.MethodsNine matches were analysed. Overall, there were 559 (M: 353; F: 206) shots, of which 54.7 ± 9.4% were successful and 19.9 ± 7.1% were goalkeepers’ saves. Type of shot, shooting area, and goal area were recorded. Percentages of differences between genders were also computed. Players’ efficiency was calculated as (frequency of goals*100)/frequency of shots. Goalkeepers’ efficiency was calculated as (frequency of goalkeepers’ saves*100)/frequency of shots. Gender differences were ascertained by Pearson’s chi-squared test for independence with Bonferroni corrections. Statistical significance of the results was accepted at <i>p</i> < 0.05.ResultsNo statistically significant gender differences were found for any parameter. Goalkeepers were most efficient (M: 23.0 ± 6.1%; F: 25.9 ± 18.0%) when receiving inflight shots. The most frequent shooting area was the front (M: 328 shots; F: 194 shots) and most shots reached lower corners of the goal (M: 139 shots; F: 77 shots).ConclusionsNo differences between genders were found during semifinal and final phases of the tournament. Notational analysis proved to be a valuable tool for better coaching through the interpretation of shots in beach handball and it may be useful to examine all the aspects related to shooting, such as the shooting area and the goal area.

IntroductionRheumatoid arthritis (RA) is categorized as an autoimmune disease with a frequency of 0.2–1% worldwide. It is reported that various autoantibodies are produced in the RA population, particularly against citrullinated peptides. Among various candidate markers for RA diagnosis, the citrullinated proteins have the highest specificity and sensitivity for both diagnosis and prognosis of RA. Anti-mutated citrullinated vimentin and -enolase constitute a new class of autoantibodies for early detection of RA.Material and methods45 serum samples and 19 synovial fluid (SF) specimens collected from RA patients were considered for American College of Rheumatology criteria and 20 serum samples and 10 SF specimens were provided from healthy subjects as a control group. To assess the quantity of anti-citrullinated protein antibodies (ACPA), anti-mutated citrullinated vimentin (MCV) and anti--enolase in the serum and SF of RA patients were determined by the enzyme-linked immunosorbent assay (ELISA) method. For the evaluation of disease activity and joint destruction, we used the Disease Activity Score of 28 joints based on erythrocyte sedimentation rate (ESR) Disease Activity Score 28 (DAS28). Furthermore, to measure the molecular weight of vimentin and -enolase, electrophoresis on 10% SDS-PAGE was performed as described before.ResultsThe anti--enolase level among serum samples from RA patients was significantly higher than in healthy subjects (4.49 ±0.20 ng/ml vs. 0.76 ±0.12 ng/ml) (p < 0.001). There was a direct relation between -enolase quantity and (rheumatoid factor) RF and C-reactive protein (CRP) levels. The mean ESR value in positive and negative ACPA patients was 38.2 ±22.6 mm/h and 9.2 ±5.8 mm/h respectively (p < 0.0001). The mean DAS28-ESR was 3.3. The level of anti-MCV in the serum of RA patients (244.6 ±53.3 U/ml) was higher than in serum of the healthy group (148.73 ±71.8) (p < 0.0001). The level of anti-MCV in the SF of patients was 687.5 ±148.4 U/ml.ConclusionsIn conclusion, both autoantibodies against MCV and -enolase are two important markers that increase in serum and SF of RA patients and are specific for diagnosis of RA disease.

IntroductionJuvenile idiopathic arthritis is the most common rheumatic disease in childhood. Biologic agents have changed the course of juvenile idiopathic arthritis. However, there are concerns regarding the occurrence of serious adverse events in patients receiving biologic agents. The aim of this study was to evaluate adverse events in children with juvenile idiopathic arthritis receiving biologic agents.Material and methodsThis retrospective study includes juvenile idiopathic arthritis patients receiving biologic agents. Demographic features and adverse events during biologic agents were collected from medical files. Adverse events that either resulted in death, were life-threatening, required inpatient hospitalization, or resulted in persistent or significant disability/incapacity were considered as serious adverse events.ResultsIn total, 162 juvenile idiopathic arthritis patients (55.6% female) receiving biologic agents were enrolled: 101 (62.3%) patients treated with etanercept, 27 (16.7) with tocilizumab, 14 (8.6%) with adalimumab, 15 (9.2%) with anti-interleukin 1 agents (13 canakinumab, 2 anakinra), and 5 (3.1%) with infli­ximab. 75.9% of the patients received concomitantly disease-modifying anti-rheumatic drugs, and 20.4% received disease-modifying anti-rheumatic drugs plus corticosteroid. The mean age at initiation of the biologic agent was 10.5 ±4.3 years. The mean age at the study enrolment was 12.1 ±4.5 years. The mean follow-up duration was 19.7 ±2.1 months. The most frequent adverse event was upper respiratory tract infections (54.3%) followed by urinary tract infections (21%). Anaphylaxis occurred in 3 patients (1.9%): 2 with tocilizumab and one with infliximab. Macrophage activation syndrome occurred in 1 patient (0.6%) receiving tocilizumab. Lung tuberculosis developed in 2 patients (1.2%) receiving canakinumab. The frequency of serious adverse events in total was 6.7%.ConclusionsWhile the most frequent adverse events during biologic agents was upper respiratory tract infections, the frequency of serious adverse events was 6.7%; therefore, juvenile idiopathic arthritis patients receiving biologic agents should be carefully evaluated for these adverse events in clinical practice.

Published: January 2021

Juvenile idiopathic arthritis (JIA) is an umbrella term for a group of diseases in children younger than 16 years old lasting six weeks or longer. Synovitis may lead to destructive and irreversible joint changes with subsequent functional impairment. Prompt diagnosis is essential to prevent permanent joint damage and preserve joint functionality. In the course of JIA both the axial and peripheral skeleton may be involved in the inflammatory process, but the knee joint is most frequently affected. New drugs and treatment protocols have forced the need for diagnosis at the earliest possible stage. Magnetic resonance imaging (MRI) allows early detection of lesions and constitutes a superior diagnostic imaging method. Synovitis, tenosynovitis, enthesitis, bursitis, osteitis, cartilage loss, bone cysts, and erosions are lesions diagnosed in JIA, and they can be precisely imaged in MRI. <br />
This article aims to present MRI inflammatory features of the knee in children with JIA based on the literature.

Published: January 2021

A pesar de que la vegetación arbórea y arbustiva leñosa se halla intervenida y deteriorada en la zona altoandina, existen especies como fuentes de energía. El estudio se desarrolló en 12 comunidades campesinas localizadas en las microcuencas de los ríos Patacancha (Ollantaytambo-Urubamba) y Lares (Lares-Calca); han sido identificadas 56 especies nativas empleadas como leña; estas especies son utilizadas por las comunidades campesinas ubicadas por encima de 3,200 msnm en la cordillera del Vilcanota. El requerimiento comunal de leña y energía es de 1.754 kg. de combustible por persona al día; esto implica un consumo en valores de energía de 12,170.88 kJ/kg,lo que significa un consumo de 0.0227 GJ persona/día. El 62.71% del combustible utilizado por las comunidades altoandinas proviene de bosques nativos, el 13.97%, de la bosta de ganado y el 23.3% del eucalipto. Si esta demanda es comparada con la oferta de leña existente en los bosques nativos, se concluye que existe un déficit de oferta de energía por parte de la biomasa vegetal existente en los bosques montanos altoandinos. Se han identificado especies de interés parala recuperación de los bosques altoandinos, como las que pertenecen a los géneros: Polylepis, Escallonia,Hesperomeles, Duranta, Citharexylum, Vallea, Berberis, Myrcianthes que poseen un alto poder calorífico que fluctúa entre 11,500 y 12,500 KJ/kg.

Robots and animals in care and law enforcement
In law enforcement animal assisted interventions have become popular. Unfortunately in evaluation studies often animal welfare is not included. The question rises to what extent this work might be harmful for participating animals and what alternatives we may offer. In this contribution we describe how robots have been introduced and are being used in the world of care. Might robots be a good alternative for animal participation in risky situations in law enforcement? We conclude by raising a number of pertinent questions for further research.

Published: January 2021

Members of extremely halophilic archaea, currently consisting of more than 56 genera and 216 species, are known to produce their specific bacteriocin-like peptides and proteins called halocins, synthesized by the ribosomal pathway. Halocins are diverse in size, consisting of proteins as large as 35 kDa and peptide “microhalocins” as small as 3.6 kDa. Today, about fifteen halocins have been described and only three genes, halC8, halS8 and halH4, coding C8, S8 and H4 halocins respectively have been identified. In this study, a total of 1858 of complete and nearly complete genome sequences of Halobacteria class members were retrieved from the IMG and Genbank databases and then screened for halocin encoding gene content, based on the BLASTP algorithm. A total of 61 amino acid sequences belonging to three halocins classes (C8, HalH4 and S8) were identified within 15 genera with the abundance of C8 class. Phylogenetic analysis based on amino acids sequences showed a clear segregation of the three halocins classes. Halocin S8 was phylogenetically more close to HalH4. No clear segregation on species and genera levels was observed based on halocin C8 analysiscontrary to HalH4 based analysis. Collectively, these results give an overview on halocins diversity within halophilic archaea which can open new research topics that will shed light on halocins as marker for haloarchaeal phylogentic delineation.
Numerical Investigation of Natural Convection and Entropy Generation of Water near Density Inversion in a Cavity Having Circular and Elliptical Body
Authors: Minh Phu Nguyen , Van Hap Nguyen 
Published: January 2021

In this chapter, a water-filled square cavity with left hot wall and right cold wall was numerically investigated. The hot and cold wall temperatures are 10°C and 0°C respectively to examine the density inversion of natural convection water, i.e. water at 4°C. In the middle of the square, there are circular and elliptical bodies to study fluid–structure interaction in terms of the thermohydraulic behavior and entropy generation. 2D numerical simulation was performed using finite volume method in Ansys fluent software with the assumption of laminar flow. The simulation results are compared with benchmark data to determine reliability. The results indicate that the body insertions increase the convection heat transfer coefficients at the best heat transfer positions due to impingement heat transfer. An increase in heat transfer rate of 1.06 times is observed in the case of circular body compared to none. There are three primary eddies in the cavity with bodies, whereas the cavity without body has two primary eddies. Maximum entropy generation was found in the upper right corner of cavity mainly due to high horizontal temperature gradient. Bodies of circle and vertical ellipse have almost the same thermohydraulic and entropy generation characteristics due to the same horizontal dimension which mainly effects on the downward natural convection current. The entropy generation of cavity with circular body is 1.23 times higher than that of the cavity without body. At positions y/L = 1 on the hot wall and y/L = 0.74 on the cold wall, the convection heat transfer coefficient is close to zero due to stagnant fluid.
O que acontece quando eu olho para você: o espaço íntimo do teatro na prisão para prisioneiros e voluntários
Authors: Hamer Karen , Martin Cedric 
Published: January 2021

Apesar dos crescentes estudos sobre teatro e voluntários nas prisões, há pouca pesquisa que olha para a experiência teatral da prisão através dos olhos tanto dos voluntários externos quanto dos prisioneiros-participantes. Este artigo busca tecer as vozes dos coautores para explorar experiências compartilhadas da sala de aula do teatro prisional. Essas experiências – descritas como "mágicas" e "transcendentes" – dependem do voluntariado navegando com sucesso na entrada na prisão. O espaço da sala de aula do teatro prisional torna-se então um refúgio relacional onde tanto os presos quanto os voluntários podem se sentir bem-vindos e aceitos, vistos não como outros, mas como essenciais.

Published: January 2021

Modelización, usando ecuaciones estructurales, del grado de satisfacción de los profesores universitarios de contabilidad sobre el trabajo fin de grado.
La baja satisfacción que el colectivo de profesores universitarios de Contabilidad muestra ante el proceso de tutorización del Trabajo Fin de Grado es lo que ha motivado la realización del trabajo; además, existe mucho interés, por parte del colectivo de profesores, en conocer que factores son los que están influyendo en ese estado de satisfacción.
El objetivo del estudio es detectar qué factores explican el citado estado de satisfacción y modelizar dicha relación.
Se han identificado y estudiado los elementos que han podido influir en la construcción de dicho estado de opinión y se han extraído, mediante análisis factorial exploratorio, 5 factores: aceptación de la metodología, percepción de competencia, competencias genéricas, importancia de competencias instrumentales, importancia de competencias sistémicas.
Los resultados evidencian las relaciones entre los constructos y la satisfacción. En conclusión, si queremos construir una estrategia docente que refuerce el grado de satisfacción del profesor universitario de Contabilidad en la labor de tutela del TFG, esta debería centrarse en potenciar las competencias genéricas del TFG. El desarrollo de las competencias genéricas, directa o indirectamente, repercuten sobre la opinión del tutor sobre la importancia de las competencias instrumentales y sistémicas y, en consecuencia, en su satisfacción.
The low satisfaction of university accounting teachers with the mentoring process of the Final Year Dissertation (FYD) has motivated carrying out this study. Moreover, lecturers are very interested in knowing which factors are influencing this satisfaction.
The aim of the study is to detect which factors explain this state of satisfaction and model this relation.
The elements which have been able to influence this opinion have been identified and studied. Exploratory factor analysis has extracted 5 factors from them: the acceptation of the methodology, the perception of competence, generic competences, the importance of instrumental competences and the importance of systemic competences.
The results reveal the relations between the constructs and satisfaction. In conclusion, if we wish to build a teaching strategy which reinforces university accounting teachers’ degree of satisfaction in their work mentoring the FYD, this should be centred on enhancing its generic competences. The development of these generic competences directly or indirectly impacts the mentors’ opinions concerning the importance of the instrumental and systemic competences and, consequently, their satisfaction.

Published: January 2021

Las medidas implantadas para mejorar la liquidez de los municipios españoles y el principio de sostenibilidad de la deuda comercial ponen de manifiesto la importancia de controlar la morosidad pública. En este contexto, este trabajo comprueba el efecto de la regla fiscal que controla los plazos de pago y si el entorno político, socioeconómico y presupuestario incide en el periodo de pago de los ayuntamientos españoles. Para ello, se realiza un análisis exploratorio y se aplica la metodología de datos de panel (2009-2015). Los resultados contribuyen a demostrar la eficacia del control del periodo de pago y evidenciar los factores de riesgo en la situación financiera a corto plazo.
Determinants of the municipal average payment period and effectiveness of the commercial debt sustainability principle. The policies implemented to improve the liquidity of Spanish municipalities and the introduction of the commercial debt sustainability principle reveal the importance of controlling late payment by public sector. In this context, the purpose of this paper is to analyse the effect of the fiscal rule directed to control the average payment periods of public administrations and whether the political environment, socioeconomic characteristics and financial situation influence on the average payment period of municipalities. In order to achieve this goal, an exploratory analysis is carried oud and panel data methodology (2009-2015) is applied. The paper contributes to provide evidence of the effectiveness of the commercial debt sustainability principle and improves the knowledge for the analysis of short-term financial position.
