Authors: Rannama Indrek , Port Kristjan 
Published: October 2018

Abstract
The purpose of present study was to examine the bilateral differences of pedalling kinetics and thigh muscle activity patterns according to leg dominance during the 30 seconds maximal cycling exercise and to analyse the relationships between asymmetries of pedalling kinetics and muscle activity. Methods: The pedalling power (POW), power production smoothness (PS) and EMG of VL, RF and BF of 17 competitive cyclists (19.2±1.6y.; 1.82±0.07m; 74.1±8.2kg) were measured bilaterally during maximal 30s isokinetic (cadence limit 100 rpm) seated cycling exercise. The dynamics of POW, PS and normalized EMG-RMS amplitude and median frequency (MF) of dominant (DO) and non-dominant (ND) side were measured. The directional asymmetry indexes (AI%) between DO and ND side were computed and compared with student t-test for paired samples. Correlation analyse between AI(%) of pedalling kinetics and EMG patterns was made. Results: The DO side POW and PS values were significantly (p<0.05) higher than ND during the all exercise time (except POW between 5-10 sec). No significant bilateral differences were found between normalized EMG amplitude values. The AI(%) of POW and PS were significantly lowered during the exercise. Significant correlations were found between AI (%)-s of PS and VL EMG MFr (r=-0.64) and between AI(%)-s of POW and VL normalized EMG amplitude (r=0.63).Conclusions: Results of the present study indicate that during 30 seconds maximal intensity cycling does exist leg dominance dependent asymmetries in pedalling power patterns, which decreased during the exercise and was related with bilaterally asymmetry of vastus lateralis muscle firing patterns.

Published: October 2018

Abstract
The purpose was to investigate the effects of simultaneous endurance and strength training repeatedly performed in the same training sessions (hybrid training). Twenty-six habitually active female physical-education students took part in the study. They were assigned to a hybrid training group (HT) or one of two control groups (CON1; only endurance training and CON2; maintained their normal training regimen). In a pre- and post-test training design all the subjects were tested before and after the intervention period concerning peak oxygen uptake while pedalling on a cycle ergometer and power output in a progressive cycle ergometer pedalling power/strength test. The HT intervention group and the CON1 group trained three times per week for five weeks, while the CON2 group did not change their normal training regimen. The HT group used a pre-programmed cycle ergometer to pedal at a mean oxygen uptake of 70-75% VO2peak for 30 minutes, but the training time was divided into 60 intermittent work periods (6 seconds) at a very high relative intensity (approximately 190 % of VO2peak) interspersed with low-intensity work periods (24 seconds) at about 45% of VO2peak. The CON1 group trained at the same mean oxygen uptake level as the HT group but during 30 minutes continuous training. The HT group significantly increased VO2peak and muscle power performance. The CON1 group increased VO2peak significantly but not power/strength. The CON2 group did not change significantly in the parameters studied. Thus, it can be concluded that in-session hybrid training allows simultaneous significant improvements of both VO2peak and muscle power performance during cycle ergometer pedalling.

Abstract
World experience shows that the means of physical culture and sports have a universal ability of a complex approach to solving problems of people’s health improving and formation of a sound psychological climate in labor collectives and in the community as a whole. Physical culture and sports is a preventive tool for health maintaining, promotion and prevention of various noninfectious diseases (cardiovascular, coronary heart disease, diabetes, osteoporosis, obesity, etc.) and bad habits (drinking, smoking, toxicomania, etc.). Moreover, as it is noted by American and European experts, the use of physical activity and sport in order to prevent morbidity requires very slight additional costs from the state. Currently, in Belarus there is an urgent need in drastic measures aimed at improving the quality of public health, formation of new guideline values in the youth, and in fitness culture development. Encompassing various forms of motor activity, fitness meets the needs of different social groups in sports and recreational activities at the expense of fitness programs diversity, their accessibility and emotionality. It promotes not only the motor, but also the general culture of the people involved. Possessing significant adaptation and integrative capabilities, fitness is a phenomenon of modern physical culture with a multifunctional impact on various spheres of public life. This favors its integration into all kinds of physical activities. Because of differences in the approaches of American, European and Belarusian practices in the use of fitness we propose improvement of public health by creating a cluster in fitness of Belarus.

Abstract
This study gives unsteady radiative magneto hydrodynamic Carreau-Casson fluids in suspension of graphene particle with Cattaneo-Christov model. A simulation is performed by mixing of graphene nanoparticles into the base water. The arising set of governing partial differential equations (PDEs) are transformed into set of ordinary differential equations (ODEs) using similarity transformations and then solved numerically using shooting technique with Runge-Kutta (RK) method. The computational results for non-dimensional temperature and velocity profiles are presented through graphs and tables. We also presented the numerical values of physical quantities (friction factor and local numbers) for various physical parameters. We compared the present results with existing literature under some limited case. At the end of this analysis we concluded that, the temperature profiles are higher in Casson fluid when compared to Carreau fluid. Similarly, the friction between the particles is more in Casson fluid compare to Carreau fluid, and heat transfer rate is high in Carreau fluid compared to Casson fluid. This help us to conclude that the cooling treatment by using Casson fluid is useful compared to Carreau fluid over unsteady sheet.

Abstract
Terahertz (THz) pulse imaging exhibits a potential application in biomedicine, nondestructive detection and safety inspection. However, the THz time-domain spectroscopy system will affect the THz image quality. To improve the THz image quality, in this article we proposed a novel method by combining the ant colony algorithm with the compressive sensing method. First, the image edge is detected by using the ant colony algorithm. Subsequently, the compressive sensing method based on signal sparse representation and the reconstruction algorithm from partial Fourier is applied on the non-edge image for noise reduction. Finally, the reconstruction result is obtained by combining the noise reduced non-edge image with the edge image. The experimental results on three kinds of images prove that the proposed method can preserve the edge information during noise reduction.

Abstract
Blends of rubber-rubber have desired properties intermediated between two rubber matrices. On the other hand, polymer-clay nanocomposites have attracted the attention of many researchers and experimental results are presented in a large number of recent papers and patents because of the outstanding mechanical properties and low gas permeability that are achieved in many cases. Polymer-clay nanocomposites are a new class of mineral-field polymer that contain relatively small amounts (<10%) of nanometer-sized clay particles. In this study, new nanocomposite materials were produced from the blend of polybutadiene rubber (BR) and ethylene propylene diene monomer rubber (EPDM), BR/EPDM (50/50) as matrix and organically modified vermiculite clay (VMT) by quaternary alkylammonium in different contents (3, 6, 9 and 12 phr) as the filler by using rubber mill then, the rubber nanocomposite sheets were irradiated at doses of 25, 50, 75, 100 and 150 kGy using γ-radiation technique as a crosslinking tool. The prepared composites can be characterized by using various analytical techniques including X-ray diffractometer (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR) as well as mechanical properties measurements.

AbstractA 35-year-old female athlete appealed to her sports physician on new onset of frequent palpitations, just before an important competition. Initial electrocardiography revealed unifocal premature ventricular complexes in the form of bigeminy. Echocardiography revealed fine-granulated hyperdensic changes in septum. Global strain rate was within a range normal, as well as pulsed tissue Doppler ultrasound. Patient was referred for cardiac MRI, which revealed interventricular septum with rougher compounds, but with preserved continuity, with thickness of 10 mm, which is in the middle of the LV, in length of 5 mm, thinned to a thickness of 4 mm. ELISA laboratory test demonstrated an increased titer of IgM antibodies for adenovirus. Six months later, the patient was referred for control MRI of the heart, which showed pronounced trabeculation of infero-lateral wall of the left ventricle, but without certain criteria for non-compaction cardiomyopathy. There was T1 oedema component in apical septal segment and apical segment of the left ventricle. There was increase of the signal in late gadolinium enhancement in the medial parts of the same segments but also in the segment of the basomedial septum, with previous focal myocarditis. These findings suggest myocardial fibrosis in the segments that were stricken by myocarditis, now without active ongoing myocarditis, but without consequent myocardial fibrosis.
Can a Taylor rule better explain the Fed’s monetary policy through the 1920s and 1930s? A nonlinear cliometric analysis
Authors: Damette Olivier , Jawadi Fredj , Parent Antoine 
Published: October 2018

AbstractThis paper investigates whether a variant of a Taylor rule applied to historical monetary data of the interwar period is useful to gain a better understanding of the Fed’s conduct of monetary policy over the period 1920–1940. To this end, we considered a standard Taylor rule (using two drivers: output gap and inflation gap) and proxied them differently for robustness. Further, we extended this Taylor rule to a nonlinear framework while enabling its coefficient to be time-varying and to change with regard to the phases in business cycle, in order to better capture any further asymmetry in the data and the structural break induced by the Great Depression. Accordingly, we showed two important findings. First, the linearity hypothesis was rejected, and we found that an On/Off Taylor Rule is appropriate to reproduce the conduct of monetary policy during the interwar period more effectively (the activation of drivers only occurs per regime). Second, unlike Field [Field, A. 2015. “The Taylor Rule in the 1920s.” Working Paper], we validated the use of a Taylor rule to explain the conduct of monetary policy in history more effectively. Consequently, this nonlinear Taylor rule specification provides interesting results for a better understanding of monetary regimes during the interwar period, and offers useful complements to narrative monetary history.
Arabic stress in strict CV, with no moras, no syllables, no feet and no extrametricality
Authors: Faust Noam , Ulfsbjorninn Shanti 
Published: October 2018

AbstractThis paper continues the effort that began in (Scheer, Tobias & Peter Szigetvari. 2005. Unified representations for stress and the syllable.Phonology22(1). 37–75.) to present a compelling alternative to moraic accounts of stress systems, framed in the theory of Strict CV (Lowenstamm, Jean. 1996. CV as the only syllable type. In Jacques Durand & Bernard Laks (eds.),Current trends in phonology models and methods, 419–442. European Studies Research Institute, University of Salford.). We have chosen stress in Palestinian Arabic, a stronghold of moraic theory, to be the empirical basis of the paper. It is a complex system, involving syllable structure and stress assignment, quantity sensitivity and syllabically-determined stress shift. Moreover, its analysis requires the deployment of a great deal of the theoretical machinery that has been (independently) developed in moraic stress theory. These phenomena, although recurrent cross-linguistically, remained outside the scope of Scheer and Szigetvari’s work. The present paper provides an account of these patterns using the innovative grid-based notion of weight incorporation (Ulfsbjorninn, Shanti. 2014.A Field Theory of Stress: the role of empty nuclei in stress systems. SOAS – University of London, PhD Dissertation.). The analysis is also brought to bear on Cairene Arabic, which is shown to differ from Palestinian in a single parameter setting. Significant independent support is provided by the extension of the analysis to the phenomenon of vowel shortening (both metrical and final), whose distribution and motivation are shown to follow in a straightforward manner from the general account. The paper also improves on previous analyses of meter in Strict CV, as for the first time in Strict CV metrics, a computational component is explicitly formalized. We conclude with a comparison to a moraic analysis of the phenomena discussed, and argue on principled grounds that the Strict CV account is a worthy competitor to such an analysis. Like its predecessor from 2005, the present account recognizes only one unit relevant for meter: the nucleus. No appeal is made to moras, syllables, feet or extrametricality.

O uso de drogas de abuso vem tomando proporções cada vez maiores na sociedade. A cada ano é notável o surgimento de novas substâncias com capacidade de provocar dependência física ou psicológica. O Instituto de Polícia Científica da Paraíba é um órgão pertencente à Polícia Civil do Estado que possui um setor responsável pela análise de drogas apreendidas. Neste contexto, o presente estudo teve como objetivo criar um perfil de drogas de abuso admitidas no IPC-JP entre os meses de janeiro a novembro de 2017. A coleta de dados se deu através da análise de 1851 laudos referentes às admissões de drogas de abuso, onde foram extraídas as informações necessárias à pesquisa. Foi possível traçar um panorama contendo informações a respeito da incidência de drogas, dos seus métodos de análises, do trabalho da polícia e da ação do Instituto, demonstrando através dos dados a situação atual e as perspectivas de avanço nas políticas de prevenção ao uso de drogas. Os resultados apontam a maconha como à droga mais apreendida, seguida pela cocaína. As apreensões de cocaína em forma de pedra representam quase que o dobro do número de apreensões da forma em pó. Em 87% das análises o esquema analítico seguia as recomendações do SWGDRUG. Os resultados apresentados se destinam a coadjuvar com programas e ações destinados a prevenção e combate a utilização e tráfico de drogas.

AbstrakKegiatan konversi lahan di Kalimantan Barat yang cenderung terus meningkat dapat berdampak negatif bagi ketersediaan pangan masyarakat desa yang masih melakukan food gathering dan berburu dari suplai alami di sekitar desa atau berternak dengan skala keluarga. Perilaku makan yang salah disertai lokasi desa yang relatif jauh dari fasilitas kesehatan yang lengkap turut menambah risiko kesehatan dan kematian pada masyarakat desa tersebut. Penelitian ini menjelaskan dan menentukan faktor-faktor yang mempengaruhi perilaku makan tiga etnis berbeda di Kalimantan Barat, mencakup Dayak, Madura dan Tionghoa, terkait penurunan ketersediaan lahan sebagai sumber pangan. Survei dilakukan di empat kabupaten dan satu kota dengan sampel diambil secara acak dari populasi etnis Dayak (Kanayatn, Muduk, Ketungau Sesae’), Madura danTionghoa. Data perilaku makan dianalisis secara deskriptif mencakup frekuensi dan rutinitas makan, keragaman sumber makanan, estimasi pengeluaran energi harian dan klasifikasi aktivitas fisik sehari penuh, serta kondisi fisik sebagai manifestasi kegiatan makan dari 293 partisipan. Faktor-faktor yang mempengaruhi perilaku makan masyarakat pedesaan Kalimantan Barat adalah pekerjaan, keterlibatan individu dalam kelompok sosial, serta ketersediaan dan keterjangkauan sumber makanan. Konversi lahan hutan dan kebun akan mempengaruhi ketersediaan sumber makanan yang terjangkau termasuk perilaku makan sehat dan seimbang pada masyarakat pedesaan di Kalimantan Barat.AbstractMost rural communities in West Kalimantan were facing negative impact of increasing land conversion activities on their natural food supply. Improper eating behavior and limited health facilities may give more health and death risk to these people. This research described and determined the factors that influenced the eating behavior among three ethnics in West Kalimantan, namely Dayak, Madura and Chinese populations, and the potential impact of land conversion to it. Survey was conducted in four regencies and one city and random sampling was done in three sub ethnics of Dayak (Muduk, Kanayatn, and Ketungau Sesae’), Madura, and Chinese communities. The eating behavior data was analyzed descriptively included meal frequency and routines, the variety of daily food source, individual estimates of energy expenditure, body mass index (BMI) distribution, and sports habit among 293 participants. Four main factors influenced the eating behavior of rural communities in West Kalimantan including types of occupation, individual involvement in social groups, and the availability and affordability of food source. The land conversion activity will certainly influence the affordable food source availability and the eating behavior for healthy and balanced food among the rural communities in West Kalimantan.

The insecticide obtained as a 97% technical grade was diluted in acetone and applied topically to dorsum of thorax of the boll weevils. The LD50 values of methyl parathion on Mexico and E.U. cotton boll weevil populations were 0.0091 and 0.01 mg/weevil, respectively. Both values indicated susceptibility. Te LD50 value of methyl parathion on the Guatemala cotton boll weevil populations was 0.44 μ g/weevil. this value may be considered as indicative of resistance.
Impacto potencial de la taltuza (Orthogeomys sp.) en el cultivo del pejibaye (Bactris gasipaes) en Costa Rica.
Authors: Monge Javier 
Published: October 2018

The taltuzas (pocket gopher) (Orthogeomys sp.) are rodents that plague several crops from USA to Panama. Peach palm (Bactris gasipaes) is a crop in expansion that overlaps in its geographical distribution with the one of Pocket gopher. Three patterns were found by superposing the distribution maps of rodents and palms. In one pattern only one organism was present but not the other whereas in two patterns rodents and palms were coincident. Since peach palm is attacked by the taltuzas, some considerations were discussed for each pattern in relation to future expansion of this crop.
