Multilevel Models for the Analysis of Angle-Specific Torque Curves with Application to Master Athletes
Authors: Carvalho Humberto M. 
Published: January 2016

Abstract
The aim of this paper was to outline a multilevel modeling approach to fit individual angle-specific torque curves describing concentric knee extension and flexion isokinetic muscular actions in Master athletes. The potential of the analytical approach to examine between individual differences across the angle-specific torque curves was illustrated including between-individuals variation due to gender differences at a higher level. Torques in concentric muscular actions of knee extension and knee extension at 60°·s-1 were considered within a range of motion between 5°and 85° (only torques “truly” isokinetic). Multilevel time series models with autoregressive covariance structures with standard multilevel models were superior fits compared with standard multilevel models for repeated measures to fit anglespecific torque curves. Third and fourth order polynomial models were the best fits to describe angle-specific torque curves of isokinetic knee flexion and extension concentric actions, respectively. The fixed exponents allow interpretations for initial acceleration, the angle at peak torque and the decrement of torque after peak torque. Also, the multilevel models were flexible to illustrate the influence of gender differences on the shape of torque throughout the range of motion and in the shape of the curves. The presented multilevel regression models may afford a general framework to examine angle-specific moment curves by isokinetic dynamometry, and add to the understanding mechanisms of strength development, particularly the force-length relationship, both related to performance and injury prevention.

Abstract
The aim of the present study was to relate the overall rating of perceived exertion (RPE-overall) with cardiorespiratory and neuromuscular variables during stationary running with the elbow flexion/extension performed with water-floating equipment. The sample consisted of eleven women that performed the water-based exercise at submaximal cadences. The heart rate, oxygen uptake, ventilation, and electromyographic signal (EMG) from biceps brachii (%EMG BB), triceps brachii (%EMG TB), biceps femoris (%EMG BF) and rectus femoris (%EMG RF) muscles were measured during the exercise, and the overall RPE was measured immediately following its completion. The Pearson product-moment linear correlation was used to investigate associations between the variables analyzed in the present study. Significant relationships were observed between the RPE-overall and all the cardiorespiratory variables, with the r values ranging from 0.60 to 0.70 (p<0.05). In addition, the RPE-overall showed a significant (p<0.05) relationship with %EMG BB (r=0.55) and %EMG BF (r=0.50). These results suggest an association between the RPE-overall with all cardiorespiratory and two neuromuscular variables during the execution of a water-based aerobic exercise using water-floating equipment.

Abstract
Evidence of the role of ANGPTL3, a liver-secreted glycoprotein, in serum lipid turnover, led us to hypothesize that this protein may be involved in modification of the lipid profile induced by exercise-training. Given the lack of data regarding this issue, the main goal of the present study was to investigate the effects of regular participation in a recreational physical activity program on serum ANGPTL3 and selected lipid profile measures in young, apparently healthy female and male adults. We compared serum ANGPTL3, lipid profile measures, common lipid ratios, the Atherogenic Index of Plasma (AIP) and glucose in fasting blood samples derived from 22 active physical education students including active females (AF, N=6) and males (AM, N=16) with samples from 28 relatively sedentary agematched peers, including female (SF, N=9) and male (SM, N=19) individuals not involved in any regular physical conditioning program. Despite high inter-individual variability of serum ANGPTL3, there was a general tendency toward higher serum ANGPTL3 and HDL-C in women compared to men, but without significant differences related to their physical activity status. Based on both routine lipid profile measures and lipid ratios, all participants had normal lipid profiles, normal glycemia, as well as favorable anthropometric indices not suggesting increased cardiometabolic risk. However, lower levels of the TG/HDL-C ratio and AIP in physically active compared to relatively sedentary participants, reflecting the predominance of large, buoyant LDL particles, strongly support the view of beneficial healthpromoting effects of regular participation in recreational sport activities.
Effect of Kinesiotape Applications on Ball Velocity and Accuracy in Amateur Soccer and Handball
Authors: Müller Carsten , Brandes Mirko 
Published: January 2016

Abstract
Evidence supporting performance enhancing effects of kinesiotape in sports is missing. The aims of this study were to evaluate effects of kinesiotape applications with regard to shooting and throwing performance in 26 amateur soccer and 32 handball players, and to further investigate if these effects were influenced by the players’ level of performance. Ball speed as the primary outcome and accuracy of soccer kicks and handball throws were analyzed with and without kinesiotape by means of radar units and video recordings. The application of kinesiotapes significantly increased ball speed in soccer by 1.4 km/h (p=0.047) and accuracy with a lesser distance from the target by -6.9 cm (p=0.039). Ball velocity in handball throws also significantly increased by 1.2 km/h (p=0.013), while accuracy was deteriorated with a greater distance from the target by 3.4 cm (p=0.005). Larger effects with respect to ball speed were found in players with a lower performance level in kicking (1.7 km/h, p=0.028) and throwing (1.8 km/h, p=0.001) compared with higher level soccer and handball players (1.2 km/h, p=0.346 and 0.5 km/h, p=0.511, respectively). In conclusion, the applications of kinesiotape used in this study might have beneficial effects on performance in amateur soccer, but the gain in ball speed in handball is counteracted by a significant deterioration of accuracy. Subgroup analyses indicate that kinesiotape may yield larger effects on ball velocity in athletes with lower kicking and throwing skills.

Published: January 2016

Abstract
The purpose of this study was to generate more concise rule extraction from the Recursive-Rule Extraction (Re-RX) algorithm by replacing the C4.5 program currently employed in Re-RX with the J48graft algorithm. Experiments were subsequently conducted to determine rules for six different two-class mixed datasets having discrete and continuous attributes and to compare the resulting accuracy, comprehensibility and conciseness. When working with the CARD1, CARD2, CARD3, German, Bene1 and Bene2 datasets, Re-RX with J48graft provided more concise rules than the original Re-RX algorithm. The use of Re-RX with J48graft resulted in 43.2%, 37% and 21% reductions in rules in the case of the German, Bene1 and Bene2 datasets compared to Re-RX. Furthermore, the Re-RX with J48graft showed 8.87% better accuracy than the Re-RX algorithm for the German dataset. These results confirm that the application of Re-RX in conjunction with J48graft has the capacity to facilitate migration from existing data systems toward new concise analytic systems and Big Data.

Authors: Swachia Kavita , Sharma Dinesh , Singh Jatinder 
Published: January 2016

Abstract

Background: The current standard treatment for sudden sensorineural hearing loss (SSNHL) comprises of tapered course of oral corticosteroids. Intratympanic steroids are introduced as another modality of treatment, but management of SSNHL continues to be debatable. The present study was designed to evaluate the efficacy of steroids given orally and by the intratympanic route.

Methods: A prospective, randomized, open-labeled study was conducted involving 42 patients. These were randomly divided into two groups; group I patients received oral prednisone tapered over 14 days, and group II patients were treated with intratympanic methylprednisolone (40 mg/mL). One milliliter of the drug solution containing 40 mg of the drug (40 mg/mL) was injected into the middle ear cavity through the trans-tympanic route. The drug was injected twice a week for 2 weeks. The total duration of the study was 60 days, and hearing outcome was assessed on the basis of change in pure tone average.

Results: An improvement of 18.24±8.72 dB was recorded in group I patients treated with oral prednisone in comparison to 14.68±12.88 dB improvement in group II. Statistically significant improvement in hearing was observed in both groups, but it was not significant when group I and group II were compared.

Conclusions: The post-treatment outcomes among patients who receive either oral prednisone or intratympanic methylprednisolone within 2 weeks of onset of symptoms were comparable. The outcomes were affected by degree of hearing loss and association of SSNHL with vertigo.
Evaluating the Variations in Employment Relations Across Developing! Economies:	A Degrees of Informalisation Approach
Authors: Williams Colin C. 
Published: January 2016

Abstract
Conventionally, cross-national variations in employment relations systems have been compared by analysing the different characters of their formal economies (e.g., whether they are control, market or mixed economies). Recognising the persistence and even growth of informal employment, this paper examines the cross-national variations in the degree of informalisation of employment relations and then evaluates critically whether such variations are associated with: under-development (modernisation theory); high taxes, corruption and state interference (neo-liberal theory), or inadequate state intervention to protect workers from poverty (political economy theory). Reporting International Labour Organisation surveys of informal employment in 41 developing economies, the finding is that the share of the non-agricultural workforce in informal employment ranges from 83.6 per cent in India to 6.1 per cent in Serbia. Evaluating critically how these cross-national variations can be explained, support is found for the modernisation and political economy theses that associates greater informalisation with under-development and inadequate state protection of workers from poverty and the neo-­liberal corruption thesis. No evidence is found that greater informalisation is associated with the neo-liberal theses of higher taxes and more state interference. The theoretical and policy implications are then discussed.
Determinants Of Foreign Direct Investment In Transition Economies, With Special Reference To Macedonia: Evidence From Gravity Model1
Authors: Dauti Bardhyl 
Published: January 2016

Abstract
This paper accounts for the main determinants of Foreign Direct Investment stocks to 5-South East European Countries and the 10-New Member States of the European Union countries by using an augmented Gravity Model, for the purpose of calculating the potential levels of FDI stock in Macedonia. The study takes into account country specific institutional factors that determine foreign investors’ decisions from 20 core OECD countries to invest in SEE-5 and EU-NMS-10 countries. From the results of the study we find that gravity factors (market size and distance), institutional related factors (control of corruption, corruption perception index, regulatory quality, transition progress and WTO membership) and other traditional determinants of FDI (schooling, bilateral exports) appear to significantly determine inward FDI stock to the SEE region and new EU member states. The GMM estimates suggest that bilateral FDI stock is subject to persistence effects. The study additionally confirms the relatively strong gravitational character of Macedonia’s inward FDI stock.
Impact Of Financial Crisis On Hedging Effectiveness Of Futures Contracts: Evidence From The National Stock Exchange Of India
Authors: Gupta Kapil , Kaur Mandeep 
Published: January 2016

Abstract
The present study examines the impact of the 2008 financial crisis on the hedging effectiveness of three index futures contracts traded on the National Stock Exchange of India for near, next and far month contracts over the sample period of January 2000 – June 2014. The hedge ratios were calculated using eight methods; Naive hedging, Ederington’s Model, Autoregressive Integrated Moving Average, Vector Autoregressive, Vector Error Correction Methodology, Generalized Autoregressive Conditional Heteroskedasticity, Exponential Generalized Autoregressive Conditional Heteroscedasticity and Threshold Generalized Autoregressive Conditional Heteroskedasticity. The study finds an improvement in hedging effectiveness during the post-crisis period, which implies that during the high-volatility period hedging effectiveness also improves. It was also found that near month futures contracts are a more effective tool for hedging as compared to next and far month contracts, which imply that liquidity is a more important determinant of hedging effectiveness than hedge horizons. The study also finds that a time-invariant hedge ratio is more efficient than time-variant hedging. Therefore, knowledge of sophisticated econometrical tools does not help to improve hedge effectiveness.

Published: January 2016

AbstractAdrenocortical tumors are neoplasms that rarely occur in pediatric patients. Adrenocortical carcinoma (ACC) is even more uncommon, and is an aggressive malignancy with 5-year survival of 55% in a registry series. There is a lack of information on long-term endocrine outcome in survivors. We describe a 10-year follow-up in a patient who presented at 3 years 5 months with a 1-year history of axillary odor and 6 months’ history of pubic hair development with an increased clitoral size. Androgen levels were increased and a pelvic sonogram revealed a suprarenal mass of the left kidney. The tumor was successfully removed. At 6 years 11 months, androgen levels increased again. Workup for tumor recurrence was negative and the findings likely represented early adrenarche. The patient had menarche at an appropriate time and attained a height appropriate for her family.

Published: January 2016

Abstract
Circular samples are the frequent objects of "in-vitro" investigation using imaging method based on magnetic resonance principles. The goal of our investigation is imaging of thin planar layers without using the slide selection procedure, thus only 2D imaging or imaging of selected layers of samples in circular vessels, eppendorf tubes,.. compulsorily using procedure "slide selection". In spite of that the standard imaging methods was used, some specificity arise when mathematical modeling of these procedure is introduced. In the paper several mathematical models were presented that were compared with real experimental results. Circular magnetic samples were placed into the homogenous magnetic field of a low field imager based on nuclear magnetic resonance. For experimental verification an MRI 0.178 Tesla ESAOTE Opera imager was used.

Abstract
Partitioning of uranium and neodymium was studied in a ‘molten chloride salt - liquid Ga-X (X = In or Sn) alloy’ system. Chloride melts were based on the low-melting ternary LiCl-KCl-CsCl eutectic. Nd/U separation factors were calculated from the thermodynamic data as well as determined experimentally. Separation of uranium and neodymium was studied using reductive extraction with neodymium acting as a reducing agent. Efficient partitioning of lanthanides (Nd) and actinides (U), simulating fission products and fissile materials in irradiated nuclear fuels, was achieved in a single stage process. The experimentally observed Nd/U separation factor valued up to 106, depending on the conditions.
The effect of SO3-Ph-BTBP on stainless steel corrosion in nitric acid
Authors: Wilbraham Richard J. , Boxall Colin 
Published: January 2016

Abstract
SO3-Ph-BTBP is a hydrophilic tetra-N-dentate ligand proposed for An(III)/Ln(III) separation by solvent extraction, and a candidate for use in future advanced reprocessing schemes such as GANEX and SANEX. We present the first study of the effect of SO3-Ph-BTBP on the corrosion behavior of stainless steels. Specifically, studies have been performed using steels and conditions equivalent to those found in relevant nuclear reprocessing flow sheets. SO3-Ph-BTBP has been shown to have little effect on either steel passivation or reductive dissolution. However, if driven cathodically into a region of hydrogen evolution at the electrode surface or conversely anodically into a region of transpassive dissolution, observed currents are reduced in the presence of SO3-Ph-BTBP, suggesting corrosion inhibition of the steel potentially through weak absorption of a SO3-Ph-BTBP layer at the metal-solution interface. The lack of any observed corrosion acceleration via complexation of Fe3+ is surprising and has been suggested to be due to the slow extraction kinetics of SO3-Ph-BTBP as a result of a requirement for a trans- to cis-conformational change before binding.

Published: January 2016

Abstract
The crystal structure of new conformation of the CyMe4-BTBP ligand (ttc) has been presented. The ttt conformer of this compound in a form of THF solvate has been also crystallized. The geometries of six possible conformations (ttt, ttc, tct, tcc, ctc and ccc) of the CyMe4-BTBP ligand have been modeled in the gas phase and in solutions (MeOH and H2O) by DFT calculations using B3LYP/6-31G(d,p) method. According to the calculations, in the three different media the conformers with trans orientation of the N atoms in the bipyridyl moiety are the most stable.
The status of the Hoopoe (Upupa epops) in Hungary: a review
Authors: Halmos Gergő , Nagy Károly , Karcza Zsolt , Szép Tibor 
Published: January 2016

Abstract
The Hoopoe is a widespread species in Hungary with the strongest populations on the Great plains. The fact that in 2015 it became ‛The Bird of the Year’ in Hungary offers the possibility to summarise the information about the distribution, population size, dispersion, migration as well as the nature conservation status of the Hoopoe population breeding in Hungary. In the period of 1999–2014 the number of breeding pairs and trend of population level was estimated based on the Common Bird Census database. The population size was estimated as 13,500–17,500 pairs with a stable trend (slope=−1.3%, SE=2.5%) over 1999–2014. There is very limited information on migration from bird ringing, only 8 recoveries between 1928–1963 indicate, that the Hungarian population is migrating on a south-southeast direction in autumn, wintering in the eastern parts of the Sahel, possibly in Chad and Sudan and migrates back in spring following a loop migration pattern further to the east. The main conservation issues are agricultural intensification impacting feeding possibilities, lack of nesting cavities and hunting during migration.
Sex and age dependent migration phenology of the Pied Flycatcher in a stopover site in the Carpathian Basin

Published: January 2016

Abstract
Very little is known about Pied Flycatchers crossing the Carpathian Basin. We give a comprehensive picture about its migration based on the data collected during the past 26 years (1989–2014) at a stopover site in Hungary: (1) sex and age related phenological changes over the years, (2) sex, age and size dependent migration patterns during and (3) between migration periods, (4) sex and age composition in spring and in autumn and their change over years.
The timing of spring migration shifted to earlier dates in the case of males, while that of females did not change implying an increasing rate of protandry. In autumn the timing did not change, but juveniles leave the area earlier than adults. The average wing length increased during the past decades in spring in the case of both sexes. In autumn, wing length did not change significantly during the years, but it increased during the seasons in all age and gender groups.
The proportion of males is about 60% in spring and among juveniles in autumn, and it is around 39% in the adult group in autumn. The male ratio diminishes during spring, but it does not change during the autumn season. The average wing of adults is shorter in spring than in autumn. Based on this fact and the different sex ratios in the two seasons we may hypothesize that Pied Flycatchers are loop migrants on this area, and even the sexes of the same population take different routes.
