Bases legais e institucionais de planos diretores municipais: exemplos no Triângulo Mineiro, Minas Gerais, Brasil
Authors: Mauro Cláudio Antonio Di , Gomes Gláucia Carvalho
Published: December 2017

As questões urbanas, consideradas em sua complexidade, não se constituem em prioridades para as políticas governamentais brasileiras. Ou são consideradas apenas em função de determinados aspectos que, em ampla medida, não se orientam pelo que está disposto no Estatuto da Cidade. Mesmo que a Constituição Federal da República Federativa do Brasil, bem como o Estatuto da Cidade sirvam de referenciais para as administrações municipais na consideração da função social da cidade e também da propriedade urbana, ainda assim as políticas aplicadas nos municípios têm se revelado deficientes. Os instrumentos contidos no Estatuto da Cidade, mesmo quando incluídos em Leis Orgânicas de Municípios que elaboram seus Planos Diretores, contudo têm suas utilizações precárias e não atendem os objetivos de garantir a cidade para todos. Os Planos Diretores de Uberlândia e Tupaciguara (MG) são exemplos de iniciativas que apontam para aproveitamento adequado das normatizações oferecidas pelo Estatuto, mas que, na prática, não foram complementadas por legislação regulamentar e encontram-se sem aplicação em suas ricas possibilidades. Mesmo com a natureza progressista de novas práticas possíveis do Estatuto da Cidade, chama muito a atenção o fato de que nos dois municípios importantes instrumentos possibilitados pelo Estatuto da Cidade, e respaldados nos respectivos Planos Diretores, não terem sido adotados de forma sistemática.

The performance of surface barrier discharge in magnetic field driven by half bridge series resonance converter
Authors: Murdiya Fri , Febrizal Febrizal , Amri Amun
Published: December 2017

This paper reports an application of a series resonance converter as a high voltage generator to drive a surface barrier discharge with a magnetic field. The high voltage was about 5 kV with the frequency of 25 kHz. It was connected to circular aluminum plates as the anode electrode and a rectangular aluminum plate as the cathode electrode. These electrodes were separated by a glass dielectric as the barrier. The experiment result indicated that the discharge current with magnetic field was lower than without magnetic field. The plasma on the surface barrier with magnetic field was more luminous than without magnetic field. It also indicated that the area of Lissajous diagram for the surface barrier discharge with magnetic field was slightly decreased than without magnetic field. It could be concluded that the magnetic field affects the plasma progress on the surface barrier. Molecular dynamic (MD) could be used in understanding the ionization process of air molecules. The ionization energies for CO2, N2, and O2 were 0.0502 kcal/mol, 0.0526 kcal/mol and 0.430 kcal/mol, respectively in 1,000 seconds. The highest ionization energy was O2.
Enseñanza de la historia e inclusión educativa: la experiencia de tener dos alumnos ciegos en mi aula
Authors: Rodríguez Hernández Mayra
Published: December 2017

El presente artículo trata sobre la pertinencia de la enseñanza de la Historia como promotora de la inclusión educativa de dos alumnos ciegos en una secundaria regular. Se partió de la idea de que, el currículum escolar vigente tiende más hacia la exclusión, la desigualdad y la injusticia social. No obstante, el currículum puede propiciar el proceso de inclusión educativa si se hacen las modificaciones pertinentes en los diferentes elementos que lo componen. La intención en este artículo es describir cómo se buscó promover una cultura inclusiva dentro del aula. No obstante, pese a la planificación y el ambiente de trabajo que se promovía, los antecedentes marcaron ciertas prácticas excluyentes, sobre todo al principio del ciclo escolar. Al final del día, este proyecto tuvo resultados satisfactorios pues logró promover algunas prácticas inclusivas entre el grupo, desarrolló aprendizajes de los diferentes alumnos, es decir, con o sin discapacidad y aumentó la participación de los alumnos ciegos, con lo que se contribuyó al proceso de inclusión educativa. Además, se mostró que las estrategias didácticas y los contenidos históricos permiten desarrollar el pensamiento histórico de los alumnos.

Authors: Sun Mengyuan , Zhao Sufang , Wei Wei , Wu Jindan , Wang Jiping
Published: December 2017

With frequent oil spills occurring worldwide, oil/water separation technologies using materials with special surface wettability have attracted attention. In this study, a polyacrylamide hydrogel was synthesized and crosslinked onto polyester fabric via UV-initiated polymerization. The modified fabric showed superhydrophilicity and underwater superoleophobicity, which allowed water passage and inhibited oil permeation. Different oils (including corn, diesel, and pump oils) could be easily separated from water with high efficiency. By rinsing with water, the fabric could be easily cleaned and recycled, while maintaining good separation performance over ten uses. A textile-based material for oil/water separation with high flux, easy-cleaning ability, and long-term efficiency was developed.

Local economic development (LED) is part of regional development concepts which emphasizes the use of local resources and capabilities and cooperation between all components to achieve quality and sustainable development. The LED initiatives could be accomplished through (industrial) business cluster approach. Cluster is basically a grouping of businesses characterized by business commonalities in proximate locations. The cluster growth requires proper role and involvement from the all stakeholders ranging from public to private sectors such as financial institutions, non-governmental organizations, educational institutions and local communities. Water Hyacinth Cluster in Banyubiru Subdistrict of Semarang Regency is of a good example. During its development trajectories, the Water Hyacinth Cluster has faced several problems because of which the call upon multiple stakeholders involvement necessary. This study aims to figure out and measure the effectiveness of the role played by each stakeholder in the observed cluster development. This study uses a mixed method research which combines quantitative and qualitative approaches. The quantitative approach is used to measure the effectiveness of the role played by the stakeholders involved in cluster, and the qualitative approach to assess and figure out the role of stakeholders deeper. The conclusion reveals that the non-government institutions perform the most dominant involvement among the remaining stakeholders. In addition, the role in production input stage is considerably more effective to the overall cluster performance.

Assessing the surface water vulnerability to pollution in the Garang Downstream Watershed Semarang requires a study concerned with some environmental components/indicators. Vulnerability measurement through surface water susceptibility index formulation on pollution is important considering the absence of surface water pollution effect indicators in an efficient assessment system. Therefore, a multi-indicator vulnerability assessment on surface water pollution is necessary. The Surface Water Vulnerability Index to Pollution (SWVIP) is composed of five components, namely water quality (WQ), rainfall (R), land use and vegetation cover (LVC), river hydrogeometric (RH) and population (P). Regarding index development, the subindex graphs and the weighting of each component are created. The application of composite index measurement yields an equation of SWVIP = 0.29.WQI + 0.23PI + 0.14RI + 0.20.LVCI + 0.14.RHI and an index value of 73.87 including the "rather high" category that represents the "vulnerable"condition in the Garang Downstream Watershed Semarang. This suggests that the five selected components used in the index creation can provide useful information to decision making in the surface water pollution control.

Bagasse ash is a fine residue collected from the burning of bagasse in sugar factory, and it behaves as pozzolanic materials. In addition, engineering behaviour of bagasse ash can be improved by addition of cement containing high calcium. Recently, research about cement stabilized soil is continuously in progress. In this paper, a set of experiment programs were done to investigate the randomly oriented polyester fibre  inclusion in bagasse ash-cement stabilized soil.  Bagasse ash was mixed with clay in different proportions. To get the optimum curing period,  it was done light compaction test of soil with 8% cement cured with 7, 14, 21, 28 and 36 days curing period,  that was found on 28 days. The next experiment was compaction test on soil + 8% cement + 3,6,9 and 12% bagasse ash to obtain optimum bagasse ash proportion. The result indicated that optimum bagasse ash content was 9%. To ensure this result, unconfined compression test was done on the same sample. Finally, light compaction, unconfined compression and direct shear tests were done on : soil + 8% cement + 9% bagasse ash +  polyester fibre with 28 days curing period. The results showed that maximum dry density and optimum moisture content was not influenced by fibre inclusion, whereas the increase of shear strength of stabilized soil with fibre inclusion  was mainly due to improvement of internal friction angle. In unconfined compression test, the unconfined compression strength of stabilized soil was significantly improved by fibre inclusion.

Many studies have shown that land use changes in watersheds such as forests that convert to settlements, industrial and estates, have an impact on flooding. So it is important to know the correlation between the various land use changes to the discharge within a watershed. This study is a preliminary study in an attempt to assess the correlation between land cover index and peak discharge, with case studies in the Beringin River Basin.The peak discharge with the return period of 2, 5, 10, 20, 50 and 100 years are computed with HEC-HMS software, developed by Hydrologic Engineering Centre (HEC) and US Army Corps of Engineers which computes the runoff discharge from the precipitation. As for land covered index (LCI), it is defined as the sum of the land-use index (LUI). The result of the case study shows the strong correlation between the land covered index with the the runoff discharge with such relation : Q100 = -22.42LCI2 + 214.30LCI - 10.62, Q50 = -18.33LCI2 + 181.87LCI - 20.19, Q20 = -14.30LCI2 + 145.27LCI - 15.61, Q10 = -11.36LCI2 + 118.41LCI - 12.29, Q5 = -8.42LCI2 + 91.27LCI - 8.9 and Q2 = -4.44LCI2 + 53.54LCI - 4.5.

Building a Social Network for Success
Authors: Ansari Asim , Stahl Florian , Heitmann Mark , Bremer Lucas
Published: December 2017

This article proposes a framework for studying how a brand, firm, or individual can use networking activities to manage a social network and drive its success. Using data from ego networks of music artists, the article models how artists can enhance their social networking presence and stimulate relationships between fans to achieve long-term benefits in terms of music plays. The authors use a Bayesian modeling framework to model the heterogeneous and dynamic impact of networking activities on network structure and on music popularity, while relying on instrumental variables from another independent online social network to handle potential endogeneity. The results imply that artists can shape network structure via marketing activities and thereby achieve a long-term impact on success that far exceeds the direct and short-term impact in magnitude. Specifically, improving the density of ego networks enables long-term effects beyond those that stem from growth in network size.
Is Cash King for Sales Compensation Plans? Evidence from a Large-Scale Field Intervention
Authors: Viswanathan Madhu , Li Xiaolin , John George , Narasimhan Om
Published: December 2017

The pervasive use of merchandise (i.e., noncash) incentives in sales compensation plans is an empirical and theoretical puzzle given the supposed superiority of cash incentives in the standard theory (i.e., principal–agent models) as well as the scant, and contradictory empirical evidence. The authors conducted a large-scale field intervention that switched 580 salespeople at a large frozen food manufacturer away from their cash plus “merchandise points” bonus to a commensurate all-cash bonus. After controlling for salesperson, seasonality, year, and target effects, the authors estimate that sales, on average, dropped by 4.36%. Furthermore, they estimated individual-level sales changes and effort changes to validate the incentive–effort–sales causal chain. The results show that the top salespeople experienced the largest drops in sales. A post-intervention survey of social and individual difference variables reveals that salespeople from households with more discretionary financial resources and those who think more abstractly about the uses of cash income exhibited smaller reductions in effort and sales. Although the absence of a control group prevents the authors from making strong causal inferences, this set of results nevertheless provides descriptive and suggestive evidence for separate mental accounts as the most promising explanation for the greater utility provided by merchandise incentives.
Matchmaker Competition and Technology Provision
Authors: Wu Yue , Zhang Kaifu , Padmanabhan V.
Published: December 2017

Matchmaking is a complex process that requires considerable expertise. Matchmakers in various industries often advertise proprietary technologies that presumably help users find an ideal match in a short time. However, matchmakers may have incentives to provide suboptimal matchmaking services so that users remain clients longer and pay more fees. This article considers a matchmaking market with network effects and strategic consumers and analyzes under what conditions matchmakers would offer more effective versus less effective matchmaking services. The authors find that stronger pricing power paradoxically leads to lower technology provision when consumers have high valuation for the matchmaking service. Moreover, network effects typically encourage matchmakers to retain the users in the market to create positive externalities, which can result in less precise matchmaking. In addition, consumer patience prompts competing matchmakers to implement ineffective technology. In two extensions, the authors explore asymmetric two-sided markets and discuss the impacts of alternative pricing schemes on technology provision.
The Occurrence of the Broadside Ballad Ó, radost má [Oh, My Joy] Among Folk Songs
Authors: Thořová Věra
Published: December 2017

The broadside ballad O, radost ma [Oh, My Joy] was, as far as known, first printed in Kutna Hora in 1808. Later, it began to be sung to an unprecedented number of different tunes, inspired by folk and semi-folk songs, broadside ballads, church and artificial songs. Sometimes, the tune even literally quoted the folk melody. Variants of the song continued to appear in all Czech regions throughout the 20th century. In the Chodsko region, the song has become popular and has been sung as a folk song to this day.

The Comenius Museum in Přerov has an interesting collection of chapbooks of Moravian and Slovak provenance. In the early 1990s, it was processed in the form of a museum catalogue including photo documentation. There is no extant record of when the museum acquired this collection. The collection comprises more than two thousand items, the earliest of which come from the 18th century, the latest from the beginning of the 20th century. Most of them were published by the Škarnicl family. They include both secular broadside ballads and pilgrim songs, with religious themes being predominant. Some of them are kept loose while others have been bound into chapbooks with canvas, cloth or leather binding.
Love for the Homeland Is Not an Empty Phrase for Me
Authors: Pousta Zdeněk
Published: December 2017

Having passed his secondary-school graduation exam, the young patriot Jaroslav Cisař left Brno to study mathematics and astronomy in New York. He reacted to the fire of war in 1914 by his active engagement in anti-Austrian resistance, whose aim was the restoration of the independence of the Czech nation. After the arrival of T. G. Masaryk in the United States, he became his personal secretary in the spring of 1918. Following the establishment of the Czechoslovak Republic, he worked at the Czechoslovak embassy in London, from 1927 in the newspaper Lidove noviny in Brno. After the occupation, he left for emigration, where he was involved in the tasks of the Ministry of Foreign Affairs. After the change in the political situation in 1948, he was released from the Ministry of Foreign Affairs and was fortunate enough to be employed as an astronomer at the University of St Andrews in Scotland. From the 1970s, he struggled with normalisation authorities over his return to the homeland. That was successfully accomplished in 1980.

This study sought to evaluate the number of those overweight and the rate of obesity among 6- and 7-year-olds living in Poland with regard to their place of residence, the parental level of education and the number of children in the family. The analysis was based on a survey of 64 544 children (33 051 boys and 31 493 girls) living in Poland. Overweight and obesity were defined based on body mass index (BMI) using the IOTF cut-off points. To evaluate the rates of overweight and obesity occurrence in children with regard to family socio-economic status, parental level of education, the number of children in the family, and the place of residence (divided into city and village) was used. ‘Only children’ were the most likely group to be overweight or obese. These children were twice as likely to be obese as their peers living in families with four or more children. Overweight and obesity occurred more often amongst children living in cities rather than those living in rural areas. Moreover, these conditions were more frequent among children whose parents had higher levels of education. The most significant predictors of childhood overweight and obesity were the number of children in the family and the educational level of the mother.

Published: December 2017

In this paper we determine the caries frequency in children of the Early Iron Age (EIA) (the 9th – the 3d centuries BC) and the Medieval populations (the 8th – the beginning of the 15th century AD) from the Ukraine area, and compare the results with the data from several European populations who lived at the same time. The EIA is presented by 41 children skeletons, three of which were Cimmerian (the 9th – the 7th centuries BC) from the territory of contemporary Poltava region; 38 skulls from the territory of contemporary Poltava region and Crimea represented Scythian period (the 7th – the 3d centuries BC). Remains of 24 children from the Medieval populations were also examined, three of which were the ancient Hungarians from the Poltava region (the 8th – the 9th centuries AD), 6 Khazars from the Kharkiv region (the 8th – the 9th centuries), 1 child related the Old Rus culture from the Kyiv region (the 9th century), and 14 representatives of the nomadic populations in the Golden Horde period (the 13th – the beginning of the 15th century) from the Poltava and Zaporizhzhya regions. Taking in consideration the letter archaeobotanical studies we suggest that there were no major changes in the plants exploited during all the studied periods. The frequency of carious lesions in children from the Medieval populations (8.3% in individuals, 0.5% in deciduous teeth, and 0.4% in permanent teeth) is only slightly higher than those from the EIA period (2.4% in individuals and 0.2% in deciduous teeth). These indexes were not larger those of majority of European populations dated to the same historic period. Further isotopic, chemical and palaeobotanical studies of the additional sites, with sufficient sample sizes, allow us to learn so much more of the cariogenic factors in children of the past populations from the Ukraine area.
Theory of Vibrations of Sugar Beet Leaf Harvester Front-Mounted on Universal Tractor
Authors: Bulgakov Volodymyr , Adamchuk Valerii , Nozdrovický Ladislav , Ihnatiev Yevhen
Published: December 2017

The harvest and transport of sugar beet leaves during harvesting can be considered a current task in the area of sugar beet growing system development. A rotary sugar beet leaf cutting mechanism is used for achieving the significant increase in the harvester forward speed during harvest. This leads to intensive vibrations of the topping mechanism in the longitudinal vertical plane causing the decrease of harvest quality. Therefore, it is necessary to analytically determine the effect of kinematic and design parameters of the sugar beet topping mechanism front-mounted on the tractor and to discover the value of the amplitude of oscillations in the longitudinal vertical plane of its sugar beet topping mechanism. We have constructed a mathematical model of the estimated motion of this machine by means of dynamics equations in Lagrange II-kind form. A system consisting of two non-linear differential equations was obtained by developing the equivalent scheme of selected generalized coordinates and by performing the necessary mathematical transformations. This system describes the vibrations of the sugar beet topping mechanism in the longitudinal vertical plane. The optimal design and kinematic parameters of the sugar beet topper mechanism front-mounted on the tractor were determined by means of our own software and numerical solution of the differential equation system, which allows the reduction of mentioned vibrations.
Using Service Simulating Test in Designing of Tillage Combine
Authors: Oskin Sergey Vladimirovich , Tarasenko Boris Fedorovich
Published: December 2017

Determining the optimal structure of the tillage combine for working in a particular company is a very difficult task due to many factors. While searching for the optimal choice, it is necessary to strive for having fewer combines in operation, reduce the fuel costs and compensate damages due to changes in agrotechnical terms and soil compaction during the combines’ operation. In this article it is proposed to apply the Monte Carlo simulation for solving this issue. As a result of the analysis of models, it was observed that all combines can be divided into separate efficiency groups and form certain tillage complexes. After the analysis of these complexes, it was proposed to replace the tillage tools, which led to further reduction in total costs. So the transition to non-mouldboard technology in both high-efficiency and low-efficiency combines will lead to cost savings by 45%, and the introduction of new tools will reduce the fuel consumption by 61-64%. For high-efficiency machine complexes, non-mouldboard technology allows the reduction of the optimal number of aggregates by 25-32%. At the same time, the introduction of new tillage combines will reduce the number of operating combines by 50-58% due to reduced resistance and the combination of technological operations.
Evaluation of lexicon- and syntax-based negation detection algorithms using clinical text data
Authors: Manimaran J. , Velmurugan T.
Published: December 2017

Background:

Clinical Text Analysis and Knowledge Extraction System (cTAKES) is an open-source natural language processing (NLP) system. In recent development modules of cTAKES, a negation detection (ND) algorithm is used to improve annotation capabilities and simplify automatic identification of negative context in large clinical documents. In this research, the two types of ND algorithms used are lexicon and syntax, which are analyzed using a database made openly available by the National Center for Biomedical Computing. The aim of this analysis is to find the pros and cons of these algorithms.

Methods:

Patient medical reports were collected from three institutions included the 2010 i2b2/VA Clinical NLP Challenge, which is the input data for this analysis. This database includes patient discharge summaries and progress notes. The patient data is fed into five ND algorithms: NegEx, ConText, pyConTextNLP, DEEPEN and Negation Resolution (NR). NegEx, ConText and pyConTextNLP are lexicon-based, whereas DEEPEN and NR are syntax-based. The results from these five ND algorithms are post-processed and compared with the annotated data. Finally, the performance of these ND algorithms is evaluated by computing standard measures including F-measure, kappa statistics and ROC, among others, as well as the execution time of each algorithm.

Results:

This research is tested through practical implementation based on the accuracy of each algorithm’s results and computational time to evaluate its performance in order to find a robust and reliable ND algorithm.

Conclusions:

The performance of the chosen ND algorithms is analyzed based on the results produced by this research approach. The time and accuracy of each algorithm are calculated and compared to suggest the best method.
Computational modeling of the electromechanical response of a ventricular fiber affected by eccentric hypertrophy
Authors: Bianco Fabrizio Del , Franzone Piero Colli , Scacchi Simone , Fassina Lorenzo
Published: December 2017

The aim of this work is to study the effects of eccentric hypertrophy on the electromechanics of a single myocardial ventricular fiber by means of a one-dimensional finite-element strongly-coupled model. The electrical current ow model is written in the reference configuration and it is characterized by two geometric feedbacks, i.e. the conduction and convection ones, and by the mechanoelectric feedback due to stretchactivated channels. First, the influence of such feedbacks is investigated for both a healthy and a hypertrophic fiber in case of isometric simulations. No relevant discrepancies are found when disregarding one or more feedbacks for both fibers. Then, all feedbacks are taken into account while studying the electromechanical responses of fibers. The results from isometric tests do not point out any notable difference between the healthy and hypertrophic fibers as regards the action potential duration and conduction velocity. The length-tension relationships show increased stretches and reduced peak values for tension instead. The tension-velocity relationships derived from afterloaded isotonic and quick- release tests depict higher values of contraction velocity at smaller afterloads. Moreover, higher maximum shortenings are achieved during the isotonic contraction. In conclusion, our simulation results are innovative in predicting the electromechanical behavior of eccentric hypertrophic fibers.

Published: December 2017

Essential oils (EOs) exhibit a wide range of pharmacological properties, which have been reported over the years in various studies. The aim of this literature review is to present the latest findings of the immunomodulatory effects of EOs. From 2008 to 2016in vivo- and/orin vitro-studies, most of which were published in the last couple of years, have been selected based on their topic relevance, namely immunomodulatory, anti-inflammatory, antileishmanial, antiallergic, and anticancer effects of various EOs. These findings show modulation of pro- and anti-inflammatory cytokines, antiproliferative, chemotactic properties and also exert antiparasitic effects by inhibiting the pro, axenic and intramacrophagic amastigote forms of Leishmania parasites or by modulating the TH1 and TH2 immune responses. Furthermore, the EOs of some plants show the ability to reduce the mast cell degranulation and improve the airway inflammation and mucus obstruction in the cases of immediate hypersensitivity in murine models. Additionally, the cytotoxicity of some EOs against human melanoma, hepatoma, lung, prostate and breast cancer cell lines proposed their potential antitumor effect by an increased immunosuppressive (cytostatic) activity.

The harmful effects of aviation can only be reduced by using alternative fuels with excellent burning properties and a high hydrogen content in the constituent molecules. Due to increasing plastic consumption the amount of the plastic waste is also higher. Despite the fact that landfill plastic waste has been steadily reduced, the present scenario is not satisfactory. Therefore, the aim of this study is to produce JET fuel containing an alternative component made from straight-run kerosene and the waste polyethylene cracking fraction. We carried out our experiments on a commercial NiMo/Al
A two-component copula with links to insurance

Published: December 2017

This paper presents a new copula to model dependencies between insurance entities, by considering how insurance entities are affected by both macro and micro factors. The model used to build the copula assumes that the insurance losses of two companies or lines of business are related through a random common loss factor which is then multiplied by an individual random company factor to get the total loss amounts. The new two-component copula is not Archimedean and it extends the toolkit of copulas for the insurance industry.
Determinants of Critical Infrastructure Resources
Authors: Ostrowska Teresa , Krupa Tadeusz
Published: December 2017

This article is devoted to the issue of how resources are interpreted in the form of technology reactors that, as a result of unexpected circumstances, turn into pyramidal or avalanche threat dynamics. Counteracting such catastrophic, terrorist, or war situations cannot begin in the face of mass casualties or significant material losses that will require reconstruction and the work of many generations. The decisive factor is the correct long-term operation and management of the economy. The starting point of this article is the concept of resource and structural-functional relationships of resources and all their possible interpretations consistent with the functionalities they play in the human environment, human aggregates, and whole nations. The aim is to draw the reader's attention to the importance (semiotics) of qualitative specifications and dynamically changing determinants contained in the material and structural-functional properties of the resources and their channel (information) communication.

Physical activity plays a crucial role in bone mass acquisition during childhood and adolescence, with weightbearing and high-impact sport activities being more beneficial. This study sought to evaluate the impact of different sports activities on bone mineral density and content in male Portuguese athletes. Seventy adolescent boys (aged 12-15 years) including 28 futsal players (FG), 20 swimmers (SG) and 22 non-athletic adolescents used as control subjects (CG), participated in the current study. Areal bone mineral density (aBMD) and areal bone mineral content (aBMC) were measured by dual energy x-ray absorptiometry (DEXA). Futsal players had significantly higher aBMD (lumbar spine - FG: 0.95 ± 0.18, SG: 0.80 ± 0.13, CG: 0.79 ± 0.13 g/cm2,p= 0.001; pelvis - FG: 1.17 ± 0.21, SG: 0.91 ± 0.12, CG: 0.98 ± 0.10 g/cm2,p< 0.001; lower limbs - FG: 1.21 ± 0.19, SG: 0.97 ± 0.10, CG: 0.99 ± 0.09 g/cm2,p< 0.001) and aBMC (lumbar spine - FG: 51.07 ± 16.53, SG: 40.19 ± 12.47, CG: 40.50 ± 10.53 g,p= 0.013; pelvis - FG: 299.5 ± 110.61, SG: 170.02 ± 55.82, CG: 183.11 ± 46.78 g,p< 0.001; lower limbs - FG: 427.21 ± 117.11, SG: 300.13 ± 76.42, CG: 312.26 ± 61.86 g/cm2,p< 0.001) than swimmers and control subjects. Data suggest that futsal, as a weightbearing and high or odd-impact sport, may improve bone mass during childhood and adolescence.

This study determined whether a multivariate profile more effectively discriminated selected than non-selected elite youth Brazilian soccer players. This examination was carried out on 66 youth soccer players (selected, n = 28, mean age 16.3 ± 0.1; non-selected, n = 38, mean age 16.7 ± 0.4) using objective instruments. Multivariate profiles were assessed through anthropometric characteristics, biological maturation, tactical-technical skills, and motor performance. The Student’s t-test identified that selected players exhibited significantly higher values for height (t = 2.331, p = 0.02), lean body mass (t = 2.441, p = 0.01), and maturity offset (t = 4.559, p < 0.001), as well as performed better in declarative tactical knowledge (t = 10.484, p < 0.001), shooting (t = 2.188, p = 0.03), dribbling (t = 5.914, p < 0.001), speed – 30 m (t = 8.304, p < 0.001), countermovement jump (t = 2.718, p = 0.008), and peak power tests (t = 2.454, p = 0.01). Forward stepwise discriminant function analysis showed that declarative tactical knowledge, running speed –30 m, maturity offset, dribbling, height, and peak power correctly classified 97% of the selected players. These findings may have implications for a highly efficient selection process with objective measures of youth players in soccer clubs.

The Relative Age Effect (RAE) in sport has been targeted by many research studies. The objective of this study was to analyze, in amateur clubs, the RAE of soccer players, according to the sport expertise level of the team (e.g., A, B, C and subsequent) that they belong to within the same game category. 1,098 soccer players in formative stages took part in the study, with ages varying between 6 and 18 years old (U8 to U19 categories). All of them were members of 4 Spanish federated clubs. The birth dates were classified into 4 quartiles (Q1 = Jan-Mar; Q2 = Apr-Jun; Q3 = Jul-Sept; Q4 = Oct-Dec)according to the team they belonged to. The results obtained in the chi-squared test and d value (effect size) revealed the existence of RAE in the teams with the highest expertise level, “A” (X2 = 15.342, p = .002, d = 0.4473) and “B” (X2 = 10.905, p = .012, d = 0.3657). However, in the lower level teams, “C and subsequent”, this effect was not observed. Present findings show that players born during the first months of the year tend to be selected to play in teams with a higher sport expertise level of each category, due to their physical maturity. Consequently, this causes differences in terms of the experience they accumulate and the motivation that this creates in these players.

The aim of this study was to perform an electromyographic and kinetic comparison of two commonly used hamstring eccentric strengthening exercises: Nordic Curl and Ball Leg Curl. After determining the maximum isometric voluntary contraction of the knee flexors, ten female athletes performed 3 repetitions of both the Nordic Curl and Ball Leg Curl, while knee angular displacement and electromyografic activity of the biceps femoris and semitendinosus were monitored. No significant differences were found between biceps femoris and semitendinosus activation in both the Nordic Curl and Ball Leg Curl. However, comparisons between exercises revealed higher activation of both the biceps femoris (74.8 ± 20 vs 50.3 ± 25.7%, p = 0.03 d = 0.53) and semitendinosus (78.3 ± 27.5 vs 44.3 ± 26.6%, p = 0.012, d = 0.63) at the closest knee angles in the Nordic Curl vs Ball Leg Curl, respectively. Hamstring muscles activation during the Nordic Curl increased, remained high (>70%) between 60 to 40° of the knee angle and then decreased to 27% of the maximal isometric voluntary contraction at the end of movement. Overall, the biceps femoris and semitendinosus showed similar patterns of activation. In conclusion, even though the hamstring muscle activation at open knee positions was similar between exercises, the Nordic Curl elicited a higher hamstring activity compared to the Ball Leg Curl.

There is a large gap in knowledge regarding research on post-exercise blood changes in disabled athletes. There are relatively few data on adaptive mechanisms to exercise in disabled athletes, including disabled rowers. Two rowers from a Polish adaptive rowing settle TAMix2x that qualified for the Paralympic Games in Rio, 2016 took part in this study. They performed a progressive test on a rowing ergometer until exhaustion. The cardiorespiratory fitness measures, complete blood count, white blood cells’ distribution and 30 clinical chemistry variables describing laboratory diagnostic profiles and general health were determined. The extreme effort induced changes in all studied metabolites (glucose, creatinine, urea, uric acid, total and direct bilirubin), albumin, total protein levels in both participants. Furthermore, a post-exercise increase in aspartate transaminase activity, yet a 2-fold decrease during the recovery time in both rowers were found. White blood cell count increased 2-fold after the test. The percentages of natural killer cells were higher and total T lymphocytes were lower after the exercise protocol. There were higher percentages of suppressor/cytotoxic and lower percentages of helper/inducer T lymphocyte subsets in both studied rowers. No changes in B lymphocytes distribution were observed. Lack of inflammatory symptoms during the experiment suggests a high level of rowers’ biological adaptation to the physical effort. The different changes in physiological, biochemical and immunological variables are related to the adaptive mechanism to physical exercise allowing for improvement of performance.
