Purpose

The aim of the study was to compare the morphological characteristics of experienced futsal players with professional soccer players.

Methods

The research sample included 22 university futsal players and 22 professional soccer players. Parameters including body height and mass, skinfold thicknesses of the trunk and extremities, lower limb length, trunk width, humerus and femur bone breadths, and the circumferences of the chest, hips, thighs, and calves were used to calculate various somatic indices. Somatotyping was performed using the Heath–Carter method. Differences in the characteristics between the futsal and soccer players were analyzed using Student’s t test. Intragroup analysis was also performed on futsal players depending on player position and compared with the arithmetic means and standard deviations of all variables of the entire sample.

Results

Compared with their soccer-playing peers, the futsal players were shorter, weighed less, had shorter lower limbs, narrower hips, and smaller hip circumference and bone breadth values. In contrast, higher levels of body fat and endomorphy were noted in this group. The proportion of mesomorphs and ectomorphs were similar in both groups. Futsal goalkeepers were differentiated by greater subcutaneous adiposity and body mass. Defenders had the slimmest body shape, with relatively narrower shoulders and hips, smaller bone breadths, and lower levels of adiposity. The body build of wingers was slightly larger. Pivoters were characterized by greater body height and larger values for the characteristics measuring the lateral trunk dimensions.

Conclusions

The observed morphological differences between futsal and soccer players were mainly in body height and height-associated characteristics. This indicates that no specialized approach in futsal recruitment is currently used. This points to the need to develop a specialized approach in the player recruitment stage, as the tactical and technical constructs of futsal set the game apart from other indoor soccer games, finding that futsal players share a number of morphological similarities with handball players.

In the industrial manufacturing chain of roller bearings the hot bars are subsequently sheared into billets and these are automatically transported to the first forming stage of the press. Normally the cobalt-based hard-facing alloys for the blades are deposited by manual metal arc or plasma transfer arc welding. In the research work presented here, the hard-facing alloys are produced by spray forming to increase the life time of the tool. Long life time is expected because of the advantages of spray forming: homogeneity of the microstructure, a low segregation and absence of a heat affected welding zone. For this purpose a bi-metal composite is deposited in a co-spray process to combine the hard-facing alloy layer with a hot working steel to insert the blade into a carrier. The interface between the two different materials was analyzed in terms of porosity, hardness, adhesive strength and machinability to describe the new composite material.
Field Monitoring of Rebar Debonding in Concrete Bridge Decks under Traffic-Induced Vibrations
Authors: Beltran Miguel , Nassif Hani
Published: August 2014

Concrete deck resurfacing is conducted through staged construction under active traffic conditions in lanes adjacent to the newly poured concrete. Many engineers are concerned about the potential of cracking and rebar debonding and other factors, such as shrinkage, thermal expansion and contraction, and live loads. There is a need to evaluate these detrimental effects with techniques that are reliable under field conditions. In this paper, results are presented from a field study that measured peak rebar velocities during concrete pours. The peak velocities were then compared with experimentally established limits for the cracking potential of the concrete surrounding the rebar. However, it is often more feasible to process accelerometer measurements to obtain velocity indirectly from common processing techniques, such as direct integration. A numerical approach was developed to mitigate the various sources of error in the integration and produce accurate estimates of velocities and displacements from raw accelerometer data. The comprehensive field testing of a rehabilitated bridge span was conducted to capture the dynamic response of the bridge girders, stringers, and deck reinforcement. The bridge was monitored during the pour of a simple span and for several hours after the initial concrete placement. The response predicted by the numerical analysis compared well with the field results: the time histories of velocity and displacement were accurately reconstructed. A comparison with the established limits of peak particle velocity suggested that vibrations induced by typical truck traffic during the initial concrete setting period should not pose any significant risk of debonding.

Published: August 2014

This paper summarizes the efforts and the outcomes of a pilot student internship program developed jointly in 2012 by the Iowa Department of Transportation (DOT) and the Institute for Transportation at Iowa State University. In 2012, Iowa was the only state DOT to use federal funds for the internship program, which was initiated as a summer program with 56 interns assigned to DOT offices and projects across the state. The paid internship program was extended into the fall semester with 22 students assigned to offices in Ames, Iowa. The program had engineering and nonengineering positions and was developed to provide experiential learning opportunities, to address Iowa DOT's workforce needs, and to attract undergraduate students to transportation careers. More than 80% of the interns and more than 90% of the supervisors, choosing from multiple choice responses, rated the program outcomes as great or okay. The interns valued opportunities to work in professional settings where they had responsibilities entrusted to them, interactions with other professionals and practitioners, an opportunity to understand real-world application of their course work, and the chance to gain first-hand experience working on transportation projects, as well as to learn about expectations in a professional setting. Supervisors noted the importance of establishing a continuation of the internship and cooperative education programs for future students. Nearly 100% of the interns and fully 100% of the supervisors said that they would recommend the program to students. Because of the student contributions during the internship, Iowa DOT was able to complete many activities that would not have been completed.

Published: August 2014

In the past decade, an increasing investment in pilot programs has advanced transportation workforce development initiatives. The Transportation Education Development Pilot Program (TEDPP) at the University of Vermont Transportation Research Center (TRC) is one such initiative from FHWA's efforts toward new projects that will demonstrate successful outcomes and pathways for replication. Paralleling this initiative, developmental evaluation has emerged as a new paradigm for assessing evolving programs that are complex, innovative, and involve multiple partners and sectors. This paper provides a case study of a developmental evaluation conducted on the TEDPP initiative at the University of Vermont Transportation Research Center (TRC). The two goals of the TEDPP initiative were to encourage new entrants into the transportation workforce and to retain and improve the effectiveness of current transportation employees. Although internal formative and summative evaluation measures were addressed throughout the TEDPP implementation (2008 to 2012), a comprehensive developmental evaluation for the entire project was undertaken in 2012–2013. This study describes the developmental evaluation in terms of methodology, evaluation, key findings, and suggested recommendations for transportation workforce development projects. The TEDPP at University of Vermont TRC accomplished many important outcomes. Although these outcomes differed from those conceived at the start of the project, the overall goals were still supported. The nature of this developmental evaluation revealed unexpected benefits and provided a framework for program expansion in terms of audience and offerings. This study makes a case for including a developmental evaluation process in transportation workforce development efforts, not only to track progress but to guide continuous program innovation.
Prioratization of villages for providing safe water sources in disaster prone Sarankhola Upazila of Bagerhat district: a GIS based approach
Authors: Sultana Sarmin , Alam Md Badrul , Ahmed Kazi Matin
Published: August 2014

Sarankhola Upazila of Bagerhat district is one of the most water scarce and disaster prone areas of the country. Village level map of existing safe water options for this Upazila has been prepared using data on number of water supply technologies for each village using ArcGIS 9.1. Hydrometeorological, geological and hydrogeological data have been analyzed to decipher the geohydro-environment in order to validate site specific water supply options. Existence of different safe water options in every village alongside population density has been presented in the map in order to identify high, medium and low priority areas. It is evident from the analysis that where shallow tubewell is less successful, the safe water coverage is also low. Rainwater harvesting is the least used option despite having high annual rainfall and therefore, can be used in large numbers along with pond sand filter (PSF) in order to improve safe water coverage. Results obtained from the study can be utilized as a planning tool to optimize the safe water coverage by targeting priority areas. The map also identifies the areas suitable for a particular safe water option and can be used as a guiding tool for installing the appropriate sustainable safe water options during future interventions.

On Mechanistic Modeling of Gene Content Evolution: Birth-Death Models and Mechanisms of Gene Birth and Gene Retention
Authors: Teufel Ashley , Zhao Jing , O'Reilly Malgorzata , Liu Liang , Liberles David
Published: August 2014

Characterizing the mechanisms of duplicate gene retention using phylogenetic methods requires models that are consistent with different biological processes. The interplay between complex biological processes and necessarily simpler statistical models leads to a complex modeling problem. A discussion of the relationship between biological processes, existing models for duplicate gene retention and data is presented. Existing models are then extended in deriving two new birth/death models for phylogenetic application in a gene tree/species tree reconciliation framework to enable probabilistic inference of the mechanisms from model parameterization. The goal of this work is to synthesize a detailed discussion of modeling duplicate genes to address biological questions, moving from previous work to future trajectories with the aim of generating better models and better inference.
Field Application of Modified In Situ Soil Flushing in Combination with Air Sparging at a Military Site Polluted by Diesel and Gasoline in Korea
Authors: Lee Hwan , Lee Yoonjin , Kim Jaeyoung , Kim Choltae
Published: August 2014

In this study the full-scale operation of soil flushing with air sparging to improve the removal efficiency of petroleum at depths of less than 7 m at a military site in Korea was evaluated. The target area was polluted by multiple gasoline and diesel fuel sources. The soil was composed of heterogeneous layers of granules, sand, silt and clay. The operation factors were systemically assessed using a column test and a pilot study before running the full-scale process at the site. The discharged TPH and BTEX (benzene, toluene, ethylbenzene, and xylenes) concentrations in the water were highest at 20 min and at a rate of 350 L/min, which was selected as the volume of air for the full-scale operation in the pilot air sparging test. The surfactant-aid condition was 1.4 times more efficient than the non-surfactant condition in the serial operations of modified soil flushing followed by air sparging. The hydraulic conductivity (3.13 × 10−3 cm/s) increased 4.7 times after the serial operation of both processes relative to the existing condition (6.61 × 10−4 cm/s). The removal efficiencies of TPH were 52.8%, 57.4%, and 61.8% for the soil layers at 6 to 7, 7 to 8 and 8 to 9 m, respectively. Therefore, the TPH removal was improved at depth of less than 7 m by using this modified remediation system. The removal efficiencies for the areas with TPH and BTEX concentrations of more than 500 and 80 mg/kg, were 55.5% and 92.9%, respectively, at a pore volume of 2.9. The total TPH and BTEX mass removed during the full-scale operation was 5109 and 752 kg, respectively.
3D Building Roof Modeling by Optimizing Primitive’s Parameters Using Constraints from LiDAR Data and Aerial Imagery
Authors: Zhang Wuming , Wang Hongtao , Chen Yiming , Yan Kai , Chen Mei
Published: August 2014

In this paper, a primitive-based 3D building roof modeling method, by integrating LiDAR data and aerial imagery, is proposed. The novelty of the proposed modeling method is to represent building roofs by geometric primitives and to construct a cost function by using constraints from both LiDAR data and aerial imagery simultaneously, so that the accuracy potential of the different sensors can be tightly integrated for the building model generation by an integrated primitive’s parameter optimization procedure. To verify the proposed modeling method, both simulated data and real data with simple buildings provided by ISPRS (International Society for Photogrammetry and Remote Sensing), were used in this study. The experimental results were evaluated by the ISPRS, which demonstrate the proposed modeling method can integrate LiDAR data and aerial imagery to generate 3D building models with high accuracy in both the horizontal and vertical directions. The experimental results also show that by adding a component, such as a dormer, to the primitive, a variant of the simple primitive is constructed, and the proposed method can generate a building model with some details.
Structural Changes of Desertified and Managed Shrubland Landscapes in Response to Drought: Spectral, Spatial and Temporal Analyses
Authors: Paz-Kagan Tarin , Panov Natalya , Shachak Moshe , Zaady Eli , Karnieli Arnon
Published: August 2014

Drought events cause changes in ecosystem function and structure by reducing the shrub abundance and expanding the biological soil crusts (biocrusts). This change increases the leakage of nutrient resources and water into the river streams in semi-arid areas. A common management solution for decreasing this loss of resources is to create a runoff-harvesting system (RHS). The objective of the current research is to apply geo-information techniques, including remote sensing and geographic information systems (GIS), on the watershed scale, to monitor and analyze the spatial and temporal changes in response to drought of two source-sink systems, the natural shrubland and the human-made RHSs in the semi-arid area of the northern Negev Desert, Israel. This was done by evaluating the changes in soil, vegetation and landscape cover. The spatial changes were evaluated by three spectral indices: Normalized Difference Vegetation Index (NDVI), Crust Index (CI) and landscape classification change between 2003 and 2010. In addition, we examined the effects of environmental factors on NDVI, CI and their clustering after successive drought years. The results show that vegetation cover indicates a negative ∆NDVI change due to a reduction in the abundance of woody vegetation. On the other hand, the soil cover change data indicate a positive ∆CI change due to the expansion of the biocrusts. These two trends are evidence for degradation processes in terms of resource conservation and bio-production. A considerable part of the changed area (39%) represents transitions between redistribution processes of resources, such as water, sediments, nutrients and seeds, on the watershed scale. In the pre-drought period, resource redistribution mainly occurred on the slope scale, while in the post-drought period, resource redistribution occurred on the whole watershed scale. However, the RHS management is effective in reducing leakage, since these systems are located on the slopes where the magnitude of runoff pulses is low.
A New Database of Global and Direct Solar Radiation Using the Eastern Meteosat Satellite, Models and Validation
Authors: Amillo Ana , Huld Thomas , Müller Richard
Published: August 2014

We present a new database of solar radiation at ground level for Eastern Europe and Africa, the Middle East and Asia, estimated using satellite images from the Meteosat East geostationary satellites. The method presented calculates global horizontal (G) and direct normal irradiance (DNI) at hourly intervals, using the full Meteosat archive from 1998 to present. Validation of the estimated global horizontal and direct normal irradiance values has been performed by comparison with high-quality ground station measurements. Due to the low number of ground measurements in the viewing area of the Meteosat Eastern satellites, the validation of the calculation method has been extended by a comparison of the estimated values derived from the same class of satellites but positioned at 0°E, where more ground stations are available. Results show a low overall mean bias deviation (MBD) of +1.63 Wm−2 or +0.73% for global horizontal irradiance. The mean absolute bias of the individual station MBD is 2.36%, while the root mean square deviation of the individual MBD values is 3.18%. For direct normal irradiance the corresponding values are overall MBD of +0.61 Wm−2 or +0.62%, while the mean absolute bias of the individual station MBD is 5.03% and the root mean square deviation of the individual MBD values is 6.30%. The resulting database of hourly solar radiation values will be made freely available. These data will also be integrated into the PVGIS web application to allow users to estimate the energy output of photovoltaic (PV) systems not only in Europe and Africa, but now also in Asia.
Addressing the challenges of a new digital technologies curriculum: MOOCs as a scalable solution for teacher professional development
Authors: Vivian Rebecca , Falkner Katrina , Falkner Nickolas
Published: August 2014

England and Australia have introduced new learning areas, teaching computer science to children from the first year of school. This is a significant milestone that also raises a number of big challenges: the preparation of teachers and the development of resources at a national scale. Curriculum change is not easy for teachers, in any context, and to ensure teachers are supported, scaled solutions are required. One educational approach that has gained traction for delivering content to large-scale audiences are massively open online courses (MOOCs); however, little is known about what constitutes effective MOOC design, particularly within professional development contexts. To prepare teachers in Australia, we decided to ride the wave of MOOCs, developing a MOOC to deliver free computing content and pedagogy to teachers with the integration of social media to support knowledge exchange and resource building. The MOOC was designed to meet teacher needs, allowing for flexibility, ad-hoc interactions, support and the open sharing of resources. In this paper, we describe the process of developing our initiative, participant engagement and experiences, so that others encountering similar changes and reforms may learn from our experience.Keywords: scaling up; MOOCs; open access; professional development; online course; computer science education(Published: 28 August 2014)Citation: Research in Learning Technology 2014, 22: 24691 - http://dx.doi.org/10.3402/rlt.v22.24691

Initiated by the Service régional de l’Archéologie and the Conservation régionale des Monuments historiques, together with the Caunes-Minervois municipality, a synthesis of the archaeological data recorded during soundings recently performed within the abbey church and the southern cloister (VIIIth-XVIIIth c.) has been realized Between 1984 and 1991, thirteen excavations concerned various sectors of the conventual group buildings : we do not take into consideration the interventions which took place outside, at the foot of the choir and near the bell tower and the porch. Each operation brought to light numerous remains ; mainly sections of walls, ground levels and graves, some of which belong to a phase of activity previous to the Romanesque period. Described in a more or less developed way in excavation reports kept in the scientific archives of the S. R. A., these elements had not until now been the object of a periodisation attempt concerning the whole site. No collation of the whole set of the surveys had also been undertaken.

Quelques pistes sont proposées, thématiques autant que stratégiques, qui pourraient guider l'élaboration d'un programme exemplaire sur la dynamique de la biodiversité, sa conservation et son exploitation durable.
Focus on GABAA receptor function
Authors: Hautzel H. , Müller H.-W. , Nikolaus S.
Published: August 2014

Impairment of GABAA receptor function is increasingly recognized to play a major role in the pathophysiology of neuropsychiatric diseases including anxiety disorder (AD), major depressive disorder (MDD) and schizophrenia (SZ). Patients, method: We conducted a PUBMED search, which provided a total of 23 in vivo investigations with PET and SPECT, in which GABAA receptor binding in patients with the primary diagnosis of AD (n = 14, 160 patients, 172 controls), MDD (n = 2, 24 patients, 28 controls) or SZ (n = 6, 77 patients, 90 controls) was compared to healthy individuals. Results: A retrospective analysis revealed that AD, MDD and SZ differed as to both site(s) and extent(s) of GABAergic impairment. Additionally, it may be stated that, while the decline of GABAA receptor binding AD involved the whole mesolimbocortical system, in SZ it was confined to the frontal and temporal cortex. Conclusion: As GABA is known to inhibit dopamine and serotonin, GABAergic dysfunction may be associated with the disturbances of dopaminergic and serotonergic neurotransmission in neuropsychiatric disorders.

This study examines the relationships between visitor satisfaction and place attachment. Confirmatory factor analysis and structural equation modeling were used to test competing models of visitor satisfaction and place attachment represented as a (i) unidimensional, (ii) first-order,
and (iii) second-order factor. Data were collected from a sample of 525 visitors at the Bruce Peninsula National Park, in the state of Ontario, Canada. Results indicate visitor satisfaction is a better predictor of place attachment as a second-order construct. Findings are discussed with respect
to their applied and theoretical relevance. Practical applications of the study include strategies aimed at achieving optimum visitor satisfaction and promoting place attachment in national parks.
Extension education strategy for minimizing aflatoxin impact on sub-Saharan African agriculture and food systems
Authors: Ayeni A.
Published: August 2014

Sub-Saharan Africa (SSA) is the most vulnerable region of the world to all aflatoxin-related problems including food insecurity, ill health and reduced foreign exchange earnings. Aflatoxin-contaminated maize, groundnuts (peanuts), sorghum and other crops reduce human access to adequate calories from these staples; consumption of aflatoxin-contaminated foods results in severe health conditions, including liver cancer, that deny the region a significant amount of otherwise productive man-hours; while the reduction of grain quality below the international standards due to aflatoxin contamination drastically reduces income in foreign exchange earnings. Scientific knowledge of the causes of aflatoxins in agricultural systems and their mitigation abounds in research institutions in SSA and internationally, but most of this knowledge is unavailable to farmers, food consumers and policy makers in useful form due to poor extension education and ineffective extension services. A paradigm shift in the approach to extension in SSA is proposed, one driven by a sustainable mechanism that is sensitive to the needs of the people and proactive (rather than reactive) in providing solutions to aflatoxin-related problems the local community and policy makers have to deal with. This paper argues that such sustainable mechanism may only be found in a University-based and University-run ‘land grant’ type extension services adapted appropriately to SSA conditions.

Estación de tratamiento de lodos - Orly (Francia)
Authors: Salmona J.
Published: August 2014

El artículo explica los problemas principales que se les han planteado a los autores del proyecto y cómo han tratado de resolverlos:
- recepción de lodos procedentes de los decantadores y concentración preliminar;
- recuperación del sulfato de alúmina por tratamiento al ácido con decantación de lodos acidificados;
- tratamiento de lodos con neutralización y filtración en vacio.
Aunque todavía es pronto, parece ser que los resultados obtenidos en esta instalación —tal vez la única del mundo— son muy alentadores y marcan un interesante camino a seguir.

Centro parroquial de la catedral católica Santa María - Tokio (Japón)
Authors: Kenzo Tange Asociados y arquitectos
Published: August 2014

La Casa parroquial y Centro católico (situados cerca de la entrada principal del conjunto que forman con la Catedral) contienen: salas para reuniones —pequeñas y grandes—, un salón de actos, residencia para sacerdotes, y las oficinas parroquiales.
Desde el punto de vista de la composición arquitectónica del conjunto creado, estos edificios han ayudado, tanto por la textura de los materiales empleados en los mismos como por su diseño, a armonizar la línea arquitectónica audaz de la Catedral con la humana de los edificios circundantes, evitando así un salto brusco de escalas.
Ciudad Sanitaria de la Seguridad Social «La Fe» - Valencia (España)
Authors: De Zavala y Lafora Juan , Flórez Plaza Fernando , Picabea Cervino Javier
Published: August 2014

Este complejo sanitario, construido con precisión y notable rapidez, resuelve de manera rotunda toda una serie de urgentes necesidades planteadas en la provincia. Se recogen en él todas las experiencias anteriores en centros similares del país, con incorporación de todo tipo de adelantos técnicos, de materiales y de instalaciones que, año tras año, se van perfeccionando de forma acelerada en este tipo de edificios.
En la redacción del proyecto se han tenido muy en cuenta, para resolverlas acertadamente, las premisas esenciales planteadas de funcionalidad, investigación y enseñanza.
El programa completo, con unas 1.100 camas para enfermos abarca siete partes bien diferenciadas: Hospital Residencia general; Centro de rehabilitación; Maternidad; Hospital infantil; Escuela de enfermeras; Laboratorios centrales, de investigación y cirugía experimental y Servicios generales (central térmica, tratamiento de aguas, lavandería, incineración, mortuorio, etcétera).
Se ha estudiado cuidadosamente la habitación tipo, tendiendo a la máxima flexibilidad de ocupación, mínimo relativo de coste, máximo confort, recorridos ponderados de enfermeras, reducción de promiscuidad, etc., agrupando racionalmente el número de ellas a servir por un mismo núcleo de servicios generales.
En tres números sucesivos de INFORMES se desarrolla, de forma suficientemente expresiva, este importante conjunto edificado, que pone de manifiesto el esfuerzo ingente de la Seguridad Social española para ponerse en primera línea mundial en este terreno de la Asistencia sanitaria.

Complejo de expansión al NW. de Francfort - Alemania Federal
Authors: Apel, Beckert Arquitectos , Becker Ingeniero
Published: August 2014

Constituye el Centro Noroeste un ambicioso proyecto que viene a catalizar todas las actividades más importantes de un gran sector de la ciudad de Francfort.
Proyectado en cuatro planos superpuestos, para conseguir un fluido desarrollo del tráfico, crea una serie de calles interiores, sin tráfico rodado, en las que se desarrolla la actividad comercial y de esparcimiento.
Debido a los muchos intereses públicos y privados que se conjugaban en el proyecto, y tras largos estudios y discusiones, hubo que llegar a fórmulas de aprovechamiento que complacieran a todos en lo posible: sistema Leasing, para edificios públicos; contratos entre el municipio y adjudicatarios; alquiler ajustable en los edificios oficiales; etc.
Como elementos interesantes en el proyecto pueden destacarse: la estación del ferrocarril metropolitano especialmente dotada de revestimiento antiacústico; la planta de estacionamiento para más de 2.000 vehículos, con entradas y salidas especiales, evitando toda clase de cruces; el sistema de planos de peatones, y abastecimiento con calles interiores para entrega de mercancías, rampas especiales, zonas de paso, etc.
