Authors: Allisse Maxime , Sercia Pierre , Comtois Alain-Steve , Leone Mario 
Published: August 2017

Abstract
The purpose of this study was to describe the evolution of morphological, physiological and skating performance profiles of elite age-group ice hockey players based on repeated measures spread over one season. In addition, the results of fitness tests and training programs performed in off-ice conditions and their relationship with skating performance were analyzed. Eighteen high level age-group ice hockey players (13.1 ± 0.6 years) were assessed off and on-ice at the beginning and at the end of the hockey season. A third evaluation was also conducted at the beginning of the following hockey season. The players were taller, heavier, and showed bone breadths and muscle girths above the reference population of the same age. Muscular variables improved significantly during and between the two hockey seasons (p < 0.05). However, maximal aerobic power improved only during the off-season. All skating performance tests exhibited significant enhancements during the hockey season, but not during the off-season where some degradation was observed. Finally, weak observed variances (generally <20% of the explained variance) between physiological variables measured off-ice and on-ice skating performance tests indicated important gaps, both in the choice of the off-ice assessment tools as well as in training methods conventionally used. The reflection on the best way to assess and train hockey players certainly deserves to be continued.

Abstract
Real Madrid was named as the best club of the 20th century by the International Federation of Football History and Statistics. The aim of this study was to compare if players from Real Madrid covered shorter distances than players from the opposing team. One hundred and forty-nine matches including league, cup and UEFA Champions League matches played by the Real Madrid were monitored during the 2001-2002 to the 2006-2007 seasons. Data from both teams (Real Madrid and the opponent) were recorded. Altogether, 2082 physical performance profiles were examined, 1052 from the Real Madrid and 1031 from the opposing team (Central Defenders (CD) = 536, External Defenders (ED) = 491, Central Midfielders (CM) = 544, External Midfielders (EM) = 233, and Forwards (F) = 278). Match performance data were collected using a computerized multiple-camera tracking system (Amisco Pro®, Nice, France). A repeated measures analysis of variance (ANOVA) was performed for distances covered at different intensities (sprinting (>24.0 km/h) and high-speed running (21.1-24.0 km/h) and the number of sprints (21.1-24.0 km/h and >24.0 km/h) during games for each player sectioned under their positional roles. Players from Real Madrid covered shorter distances in high-speed running and sprint than players from the opposing team (p < 0.01). While ED did not show differences in their physical performance, CD (p < 0.05), CM (p < 0.01), EM (p < 0.01) and F (p > 0.01) from Real Madrid covered shorter distances in high-intensity running and sprint and performed less sprints than their counterparts. Finally, no differences were found in the high-intensity running and sprint distances performed by players from Real Madrid depending on the quality of the opposition.

Abstract
The aim of the study was to describe and compare kinematics in two types of execution of attack hit, the goofy approach and regular approach. The research group consisted of players from the Czech Republic’s top league (n = 12, age 28.0 ± 4.3 years, body height 196.6 ± 5.6 cm, body mass 89.7 ± 6.7 kg) divided into two groups according to the individual type of approach in the attack. Analysis of movement was performed by 3D kinematics video analysis, space coordinates were calculated by the DLT (Direct Linear Transformation) method together with interpretation software TEMA Bio 2.3 (Image Systems AB, Sweden). The players started their run-up from a distance of about 4 – 4.5 m from the net with similar maximal vertical velocity (2.91 – 2.96 m⋅s-1). The trajectory of players with goofy approach seemed to be convenient for the rotation of shoulders and hips in the moment of ball contact. Differences between both groups were observed. Players with a goofy approach had a longer flight phase compared to regularly approaching players.

Authors: Dirba J. , Dobriyan R. , Lavrinovicha L. , Vitolina S. 
Published: August 2017

Abstract
The paper presents the comparison of two synchronous reluctance motors with the inner rotor and the outer one. The aim of the research is to determine the influence of motor type on electromagnetic torque and ripple factor. The results indicate that a maximum value of electromagnetic torque and the amplitude of the first harmonic of electromagnetic torque increase for the motor with the inner rotor, and the value of ripple factor increases as well. If both motor types with equal rated power, rotation frequency and current density are compared, the results show a possibility to reduce the volume of motor with the inner rotor by 15 %.
Low Brightness Temperature in Microwaves at Periphery of Some Solar Active Regions
Authors: Ryabov B. I. , Bezrukov D. A. , Kallunki J. 
Published: August 2017

Abstract
The microwave regions with low brightness temperature are found to overlap the regions of the depressed coronal emission and open field lines at the periphery of two solar active regions (ARs). The imaging microwave observations of the Sun with the Nobeyama Radio heliograph at 1.76 cm, the MRO-14 radio telescope of Metsähovi Radio Observatory at 0.8 cm, and the RT-32 of Ventspils International Radio Astronomy Centre in the range 3.2-4.7 cm are used. To reduce the noise in the intensity distribution of the RT-32 maps of the Sun, one wavelet plane of “à trous” wavelet space decomposition is subtracted from each map. To locate the open-field regions, the full-Sun coronal magnetic fields with the potential field source surface (PFSS) model for RSS = 1.8 Rʘ are simulated. We conclude that the revealed LTRs present narrow coronal hole-like regions near two ARs and imply an extra investigation on the plasma outflow.

An Ecosystem Perspective On Asset Management Information
Authors: Metso Lasse , Kans Mirka 
Published: August 2017

Abstract
Big Data and Internet of Things will increase the amount of data on asset management exceedingly. Data sharing with an increased number of partners in the area of asset management is important when developing business opportunities and new ecosystems. An asset management ecosystem is a complex set of relationships between parties taking part in asset management actions. In this paper, the current barriers and benefits of data sharing are identified based on the results of an interview study. The main benefits are transparency, access to data and reuse of data. New services can be created by taking advantage of data sharing. The main barriers to sharing data are an unclear view of the data sharing process and difficulties to recognize the benefits of data sharing. For overcoming the barriers in data sharing, this paper applies the ecosystem perspective on asset management information. The approach is explained by using the Swedish railway industry as an example.

Published: August 2017

Abstract
Recent developments in information technology and business models enable a wide variety of new services for companies looking for growth in services. Currently, manufacturing companies have been actively developing and providing novel asset based services such as condition monitoring and remote control. However, there is still untapped potential in extending the service delivery to the long-term co-operative development of physical assets over the whole lifecycle. Close collaboration with the end-customer and other stakeholders is needed in order to understand the value generation options. In this paper, we assess some of the asset services manufacturing companies are currently developing. The descriptions of the asset services are based on the results of an industrial workshop in which the companies presented their service development plans. The service propositions are compared with the Total Cost of Ownership and the closed loop life cycle frameworks. Based on the comparison, gaps that indicate potential for extended asset service concepts are recognised. In conclusion, we argue that the manufacturing companies do not recognise the whole potential for asset based services and for optimizing the performance of the end customers′ processes.

Abstract
The maintenance planning corresponds to an approach that seeks to maximize the availability of equipment and, consequently, increase the levels of competitiveness of companies by increasing production times. This paper presents a maintenance planning based on operating variables (number of hours worked, duty cycles, number of revolutions) to maximizing the availability of operation of electrical motors. The reading of the operating variables and its sampling is done based on predetermined sampling cycles and subsequently is made the data analysis through time series algorithms aiming to launch work orders before reaching the variables limit values. This approach is supported by tools and technologies such as logical applications that enable a graphical user interface for access to relevant information about their Physical Asset HMI (Human Machine Interface), including the control and supervision by acquisition through SCADA (Supervisory Control And data acquisition) data, also including the communication protocols among different logical applications.

Published: August 2017

Abstract[Cu(cyclam)Ni(NCS)4(H2O)2]n(1) (cyclam = 1,4,8,11-tetraazacyclodecane) exhibits bent 1D crystal structure in which paramagnetic Cu(II) and Ni(II) atoms are linked by bridging μ2-NCS- ligands. The Cu(II) atom exhibit tetragonally elongated hexacoordination in the 4+2 form with one tetradentate macrocyclic cyclam ligands placed in the equatorial plane while the axial positions are occupied by S atoms from bridging NCS- ligands. The Ni(II) atom in NiN4O2donor set is deformed octahedrally coordinated by four isothiocyanato ligands among which two in trans positions are bridging in nature; additional aqua ligands occupy the remaining two positions in trans arrangement. Weak hydrogen bonding interactions of the O-H···S type links the formed chains into 3D supramolecular structure. The magnetism of 1 is dominated by a sizable single-ion anisotropy DNi/hc = +7.49 cm-1along with a weak exchange interaction of the ferromagnetic nature.
Dispersal and migration of a specialist waterbird: where do Eurasian Spoonbills (Platalea leucorodia) come to Hungary from?
Authors: Pigniczki Csaba 
Published: August 2017

Abstract
Between 1950 and 2016, 254 individuals of Eurasian Spoonbill (Platalea leucorodia) of foreign origin were observed during their dispersal or migration in Hungary from eight countries. Colour-ringed birds originating from Serbia, Croatia and the Czech Republic were the most commonly observed, while individuals from Italy, the Danube Delta (Romania) and the Wadden Sea area (Denmark and The Netherlands) were observed rarely in Hungary. Only metal ringed Spoonbills were recovered from Austria. All age-classes were found in Hungary: juveniles were the most common, while 2cy immatures formed the rarest class. Adults from the Wadden Sea area, and also from the Danube Delta were observed in Hungary during the breeding season, implying potential gene flow between those areas and the Carpathian Basin. My results predict that the breeding population of the Carpathian Basin forms a unique subunit of a metapopulation which is in close contact with the Czech population. The nesting of adults of Serbian and Croatian origin was confirmed in Hungary. Two prospecting subadults (4cy) were observed in Hungarian colonies, one was from Serbia, and the other was from Italy. One adult (5cy) occurred in several Hungarian wetlands in a short period before breeding, which probably explored habitats for breeding or for feeding. Spoonbills of Czech, Serbian, Croatian and Italian origin observed in Hungary used the Central Mediterranean or the Adriatic Flyway. Individuals from the East Atlantic population arrived to Hungary by shifting their migration routes. One bird from the Danube Delta wintered in Tunisia, where it probably joined Hungarian breeders and reached Hungary with them. Adults and juveniles from the Czech Republic used the wetlands around Lake Neusiedler as a stop-over and staging area during autumn migration. My results suggest that Hungarian wetlands play an important role in the movements and breeding of Spoonbills in Central Europe, thus, the management and conservation of these wetlands are essential for the future.
Interesting breeding cases of the Raven (Corvus corax) in Hungary

Published: August 2017

Abstract
Due to conservation measures, the breeding population of the Raven significantly strengthened over the last decades in Hungary, also nesting on the lowlands. Nowadays, observing large flocks is not rare. Compared to other European countries, the urbanization of the species began relatively late in Hungary, in the ‘90s, first breeding in the urban areas of Baranya County. There were another five similar known cases after the millennium across the country. Because of the advanced adaptive capacity of species, this number is likely to grow in the future. In Hungary, the brood is typically complete in the second half of February and the young birds fledge in the first days of May. There are two known cases after the millennium when the Ravens bred in a significantly different time than usual. In these cases, the young birds fledged on 20 January and the second half of February. In both cases, the nests were found on overhead transmission line poles in lowland agricultural areas. It is uncertain what led to the unusual breeding time, but it is most likely that the breeding pair was accustomed, having successfully raised several brood before, and they could rely on the abundant food base near the nests during the breeding period.

Published: August 2017

AbstractOrnithological studies often rely on long-term bird ringing data sets as sources of information. However, basic descriptive statistics of raw data are rarely provided. In order to fill this gap, here we present the third item of a series of exploratory analyses of migration timing and body size measurements of the most frequent Passerine species at a ringing station located in Central Hungary (1984-2016). First, we give a concise description of foreign ring recoveries of the Song Thrush in relation to Hungary. We then shift focus to data of 4137 ringed individuals and 1051 recaptures derived from the ringing station, where birds have been trapped, handled and ringed with standardized methodology since 1984. Timing is described through annual and daily capture and recapture frequencies and their descriptive statistics. We show annual mean arrival dates within the study period and present the cumulative distributions of first captures with stopover durations. We present the distributions of wing, third primary, tail length and body mass, and the annual means of these variables. Furthermore, we show the distributions of individual fat and muscle scores, and the distributions of body mass within each fat score category. We distinguish the spring and autumn migratory periods, breeding and wintering seasons, and age groups (i.e. juveniles and adults). Our aim is to provide a comprehensive overview of the analysed variables. However, we do not aim to interpret the obtained results, merely to draw attention to interesting patterns that may be worth exploring in detail. Data used here are available upon request for further analyses.

Verification and Updating of the Database of Topographic Objects with Geometric Information About Buildings by Means of Airborne Laser Scanning Data
Authors: Mendela-Anzlik Małgorzata , Borkowski Andrzej 
Published: August 2017

Abstract
Airborne laser scanning data (ALS) are used mainly for creation of precise digital elevation models. However, it appears that the informative potential stored in ALS data can be also used for updating spatial databases, including the Database of Topographic Objects (BDOT10k). Typically, geometric representations of buildings in the BDOT10k are equal to their entities in the Land and Property Register (EGiB). In this study ALS is considered as supporting data source. The thresholding method of original ALS data with the use of the alpha shape algorithm, proposed in this paper, allows for extraction of points that represent horizontal cross section of building walls, leading to creation of vector, geometric models of buildings that can be then used for updating the BDOT10k. This method gives also the possibility of an easy verification of up-to-dateness of both the BDOT10k and the district EGiB databases within geometric information about buildings. For verification of the proposed methodology there have been used the classified ALS data acquired with a density of 4 points/m2. The accuracy assessment of the identified building outlines has been carried out by their comparison to the corresponding EGiB objects. The RMSE values for 78 buildings are from a few to tens of centimeters and the average value is about 0,5 m. At the same time for several objects there have been revealed huge geometric discrepancies. Further analyses have shown that these discrepancies could be resulted from incorrect representations of buildings in the EGiB database.
Integrated Precipitable Water from GPS Observations and CIMEL Sunphotometer Measurements at CGO Belsk
Authors: Kruczyk Michał , Liwosz Tomasz , Pietruczuk Aleksander 
Published: August 2017

AbstractThis paper describes results of integrated precipitable water co-located measurements from two techniques: GPS solution and CIMEL-318 sunphotometer. Integrated Precipitable Water (IPW) is an important meteorological parameter and is derived from GPS tropospheric solutions for GPS station at Central Geophysical Observatory (CGO), Polish Academy of Sciences (PAS), Belsk and compared with sunphotometer (CIMEL-318 device by Cimel Electronique) data provided by Aerosol Robotic Network (AERONET). Two dedicated and independent GPS solutions: network solution in the sub-network of European Permanent Network (EPN) and precise point positioning solution have been made to obtain tropospheric delays. The quality of dedicated tropospheric solutions has been verified by comparison with EPN tropospheric combined product. Several IPW comparisons and analyses revealed systematic difference between techniques (difference RMS is over 1 mm). IPW bias changes with season: annual close to 1 mm IPW (and semi-annual term also present). IPW bias is a function of atmospheric temperature. Probable cause of this systematic deficiency in solar photometry as IPW retrieval technique is a change of optical filter characteristics in CIMEL.
Current insights in CSF leaks: a literature review of mechanisms, pathophysiology and treatment options
Authors: Patrascu Elena , Manea Claudiu , Sarafoleanu Codrut 
Published: August 2017

Abstract
A cerebrospinal fluid (CSF) leak occurs when there appears a fistula between the dura and the skull base and it is usually characterized by discharge of cerebrospinal fluid from the nose. Cerebrospinal fluid leaks may have many etiologies, the most common being trauma. The most common site of dural lesion is the cribriform plate of the ethmoid. Diagnosis can be achieved by a multitude of techniques, high-resolution computed tomography being the modality of choice and it may be completed with magnetic resonance imaging or cisternography. Treatment may be either conservative, either surgical, related to the cause, the site and the duration of CSF leak. Conservative treatment usually includes strict bed rest, elevated bed head and no straining, nose blowing or stretching, with resolution of the majority of traumatic CSF leaks in seven days. Surgical treatment consists of a variety of approaches (intracranial/extracranial, open/endoscopic). The future trend is represented by minimally invasive endoscopic approaches, with a success rate of almost 90%; however, open transcranial or extracranial interventions still have indications in the surgical management. CSF leaks must be correctly diagnosed and treated, because the risk of intracranial complications increases 10-fold when the leakage persists.

Abstract
Nasolacrimal duct obstruction (NLDO) is a common event in clinical practice. The authors, all members of the Italian Society of Rhinology, analysed 100 cases from different ENT Departments. The causes of NLDO, according to the etiology, can be divided into two classes: idiopathic primary acquired nasolacrimal duct obstruction and secondary. The aim of the study was to describe an association between the sign and symptoms of chronic rhinosinusitis and a complaint of epiphora.
