Abstract
For the safe and economical design and operation of freight pipelines it is necessary to know slurry flow behaviour in inclined pipe sections, which often form significant part of pipelines transporting solids. Fine-grained settling slurry was investigated on an experimental pipe loop of inner diameter D = 100 mm with the horizontal and inclined pipe sections for pipe slopes ranging from −45° to +45°. The slurry consisted of water and glass beads with a narrow particle size distribution and mean diameter d50
= 180 µm. The effect of pipe inclination, mean transport volumetric concentration, and slurry velocity on flow behaviour, pressure drops, deposition limit velocity, and concentration distribution was studied. The study revealed a stratified flow pattern of the studied slurry in inclined pipe sections. Frictional pressure drops in the ascending pipe were higher than that in the descending pipe, the difference decreased with increasing velocity and inclination. For inclination less than about 25° the effect of pipe inclinations on deposition limit velocity and local concentration distribution was not significant. For descending pipe section with inclinations over −25° no bed deposit was observed.
V-Function Method: Some Solutions of Direct and Inverse Dynamics Problems in A New Statement
Authors: Valishin Nail T. , Valishin Fan T. 
Published: April 2019

Abstract
Based on the V-function method, the properties of wave nature of object motion are studied for object uniform motion with constant speed and for harmonic oscillator. It follows from the V-function method that object wave motion is inseparably linked with its trajectory motion. The V-function method consists of the principle of local variation and a new statement of the direct and inverse dynamics problems. The proposed approach made it possible to make the optico-mechanical analogy that obtained a new continuation. A comparison is made with the results obtained by Schrödinger for a harmonic oscillator.

Abstract
The aim of this research study was to design and assess the design of the interior environment for a leisure learning area in the National Gallery of Thailand. The study used a combined quantitative and qualitative methodologies: interviewing the curator, 2 staff members, and the executive director of the National Gallery of Thailand; a physical survey of areas in the gallery; and a questionnaire survey of users’ preferences of art activity area. The survey of users’ preferences was conducted with a sample group of 600 potential users who were randomly and systematically sampled from a population of first-year students majoring in applied arts in several governmentally-supported universities in Bangkok. The obtained data on the designs that were based on the concept of functional and aesthetic design and a ‘circumplex model of affect’ in cognitive theory were analyzed accordingly. The preliminary designs were three arrangement patterns of environmental elements that provided positive stimuli: 1) a pattern for low level of stimuli; 2) one for moderate level; and 3) one for high level of stimuli. These patterns are illustrated in this paper as a layout plan and 3 computer-generated 3D perspectives that were assessed by 10 design experts on a 1-5 Likert rating scale. The means and standard deviations achieved by the 3 patterns indicated that the patterns for medium level and high level of stimuli was of a very high quality with ̄X = 4.5, SD = 0.14 and ̄X = 4.59, SD = 0.19, respectively. In other words, both patterns were active, functional, aesthetically-pleasing, and proper overall designs for the environmental interior of the intended area in the National Gallery of Thailand.

This research is justified by pointing out the basic conceptions of the continuing education of the university professor. The process of this research included three phases: First, the search; collection and analysis of information. Second, it includes models of professor training and theorization. Third, it raises the final conception of the educational training of the university professor. The research was developed from a qualitative perspective; therefore, it is implanted in an epistemic conceptualization that corresponds to its nature and the interest to deepen in the intuition of the object of study. In this research participated 8 (eight) professors who work at UTE. For the analysis of the data that was obtained they were applied the Grounded Theory and the Constant Comparative Method, which had the purpose of making a theoretical approximation from the categorizations and their dimensions, through the Atlas.ti operating software, version 8. Moreover, the goal was contributing to the theoretical foundation and methodology of the research which generated the following categories: professional professor role and new professor profile. In the conclusions it was mentioned the importance of the university professor updating through scientific research to promote the knowledge and strategies that demand the need to theorize, produce and raise the level of professor thinking.
Management of the Family Empowerment and Welfare Organization to Prevent Divorce in Cilacap Regency
Authors: Puspita Dyah Retna , Rostikawati Rin , Dharma Pawrtha 
Published: April 2019

Abstract
The organization Family Empowerment and Welfare (FEW, or known in Indonesia as PKK) is a social institution that receives significant and varied support from the Indonesian government due to its significant role in empowering families. It has a wide scope, reaching down to the Neighborhood Association/RT (the smallest village administrative level) and even Dasa Wisma (groups of ten families) levels. One regency in which FEW analysis is attractive is Cilacap Regency. Cilacap has the highest divorce rates in Central Java province, and there has been a degradation of family sustainability as a result. Therefore, this research aims to analyze the management of FEW in empowering families in this regency, especially in preventing divorce. This research applies a descriptive-qualitative approach, with FEW officials as its research target. Data were collected through interviews, discussions, and observations. This research shows that one cause of high divorce rates in this region is the limited function of this program and its activities, as social analysis has not been conducted as the basis for making plans. It is recommended that the social analysis strategy be implemented.
The Polish School of Composition in 20th-Century Music – A Recapitulation
Authors: Lindstedt Iwona 
Published: April 2019

Abstract
The present paper concerns the concept of ‘the Polish School of Composition’, well established in writings on music composed in the 2nd half of the 20th century, but still resisting attempts to define it clearly. I sum up the ways authors have talked about the Polish School of Composition to date, both from the internal (Polish) and external (foreign) points of view. I also examine the musical differentia specifica (such as aspects of style, composition technique and expression in works associated with this phenomenon) and the extramusical (mostly social and political) contexts which have determined the evolving approaches to the phenomenon in question. I begin with the origin of the term itself and discuss its subsequent interpretations until the present. From this perspective, the Polish School of Composition appears to be a kind of mythic narrative, a proposed way of ordering and understanding the past realities, transcending the categories of truth and falsehood, and working primarily in the sphere of emotions.
Determining the optical properties of blood using He-Ne laser and double integrating sphere set-up
Authors: Ashoor Habib E. , Jasim Khalil Ebrahim 
Published: April 2019

Abstract
The behaviour of light interaction with biological tissue is determined by micro-optical parameters: refractive index (n), absorption coefficient (µa
), scattering coefficient (µs
), and anisotropy (g). The goal of this study is to measure the optical properties of normal whole blood using He-Ne laser (wavelength 632.8 nm).
The refractive index is measured using the traveller microscope. The integrating sphere method is used to measure the macro-optical parameters: total diffusive reflectance, transmittance, and collimated transmittance at wavelength 632.8 nm. The macro-optical parameters are fed to Inverse Adding Doubling (IAD) theoretical technique, to estimate the micro-optical parameters (µs
, µa
, g). An alternative practical method is used to measure the g value based on utilising the goniometric table. The study reveals that the refractive index (n) equals 1.395±0.0547, absorption coefficient (µa
) equals 2.37 mm−1, scattering coefficient (µs
) equals 55.69 mm−1, and anisotropy (g) equals 0.82.
In conclusion, these findings approved, in general, the applicability of the suggested experimental set up. The set up depend on using three devices: the integrating sphere method to estimate (µs
, µa
, g), traveller microscope (n) and goniometer (g).
A Monte Carlo investigation of the dose distribution for new I-125 Low Dose Rate brachytherapy source in water and in different media
Authors: Fardi Zeinab , Taherparvar Payvand 
Published: April 2019

Abstract
Permanent and temporary implantation of I-125 brachytherapy sources has become an official method for the treatment of different cancers. In this technique, it is essential to determine dose distribution around the brachytherapy source to choose the optimal treatment plan. In this study, the dosimetric parameters for a new interstitial brachytherapy source I-125 (IrSeed-125) were calculated with GATE/GEANT4 Monte Carlo code. Dose rate constant, radial dose function and 2D anisotropy function were calculated inside a water phantom (based on the recommendations of TG-43U1 protocol), and inside several tissue phantoms around the IrSeed-125 capsule. Acquired results were compared with MCNP simulation and experimental data. The dose rate constant of IrSeed-125 in the water phantom was about 1.038 cGy·h−1U−1 that shows good consistency with the experimental data. The radial dose function at 0.5, 0.9, 1.8, 3 and 7 cm radial distances were obtained as 1.095, 1.019, 0.826, 0.605, and 0.188, respectively. The results of the IrSeed-125 is not only in good agreement with those calculated by other simulation with MCNP code but also are closer to the experimental results. Discrepancies in the estimation of dose around IrSeed-125 capsule in the muscle and fat tissue phantoms are greater than the breast and lung phantoms in comparison with the water phantom. Results show that GATE/GEANT4 Monte Carlo code produces accurate results for dosimetric parameters of the IrSeed-125 LDR brachytherapy source with choosing the appropriate physics list. There are some differences in the dose calculation in the tissue phantoms in comparison with water phantom, especially in long distances from the source center, which may cause errors in the estimation of dose around brachytherapy sources that are not taken account by the TG43-U1 formalism.
Ad fontes (The Codices of Revúca)
Authors: Piroščáková Jana 
Published: April 2019

Abstract
The article presents the Codices of Revúca as one of the most important sources of research on Slovak fairy tales through the interpretation of the Berona fairy tale. This topic as a whole but also in the context of the fairy tale theory is still unexplored, just like most similar manuscripts of Slovak romanticists who were at the birth of the folklore studies in their pre-scientific period. It is purposly conceived as a material study with the aim of demonstrating the need to return to archive sources and the research potential offered by such materials. It is, however, not the specific objective of this article to present an analysis of the texts quoted in the annex. The article consists of two parts. The first one evaluates the existing material base of the research on the Codices of Revúca (J. Polívka, M. Dzubáková), highlights the limitations arising from the marginalisation of the available materials, offers precise records from the Codices of Revúca on the texts for the interpretation of the fairy tale and, finally, corrects the information on one of the key texts from this source, the letter written by S. Reuss on December 17, 1843, the full translation of which forms part of the text in the annex. The second (analytical) part of the article deals with the contextualisation and comparison of three commentaries on the Berona fairy tale (S. Reuss, J. Francisci, S. Ormis). All three texts are fully available in the annex.

Published: April 2019

Abstract
Hypokinetic dysarthria is characterized by a speech that gradually becomes monotonous, poorly modulated, quiet and ultimately unintelligible. The goal of this research is to determine the acoustic characteristics of voice and speech in adults with hypokinetic dysarthria and the impact of the altered voice on the quality of communication. The sample consisted of 30 elderly respondents of both genders with Parkinson’s disease and hypokinetic dysarthria. In order to conduct a spectral analysis, the voice of patients was recorded while they were reading phonetically balanced text. The respondents conducted a self-assessment of the degree of their own handicap caused by voice disorder and impact of the voice handicap by completing the Voice Handicap Index (VHI). Statistically significant differences were determined in the position of some formants in respondents compared to the values of formants in typical speakers for the following vowels: F1 of the vowel /I/ and F2 of the vowels /E/, /I/, /O/ and /U/. By examining the relation between the score achieved on the VHI instrument and the value of formants, the only statistically significant correlation was achieved between the formant F1 of the vowel /A/ and functional and emotional subscale. By regression analysis used to determine the predictor of the quality of communication, it was confirmed that F1 of the vowel /A/ has a statistically significant contribution to the explanation of the score achieved on functional and emotional subscale, by explaining 15% of the functional subscale (Beta=-0,393 (11,30 – 47,37)) and 10% of the emotional subscale (Beta=-0,363 (-0,052 – 0,000)).
Aspects regarding the use of drugs among athletes
Authors: Gligor Șerban , Gligor Răzvan 
Published: April 2019

Abstract
Drug abuse among athletes is a current and very important issue, both ethically and in terms of health risks. In addition to the drugs prescribed for the treatment of some diseases, athletes can also use substances that artificially increase their performance, such as: stimulants, anabolics, opioids, erythropoietin, diuretics as well as substances used to mask the prohibited substances.

The aim of this study is to review the data from the literature about the use of various drugs by athletes, for therapeutic purposes, or to increase sports performance.

Methods: We identified several studies using the on-line databases, and the inclusion and exclusion criteria. Searches were limited to full-text English-language journal articles published between 2003 and 2014.

Results: After the primary analyses we selected a total of 30 relevant studies on this topic.
Even if there is progress in detecting prohibited substances that increase sports performance, doping prevalence persists in sport.

Conclusion: In order to prevent and disrupt drug abuse, appropriate measures should be taken by physicians and coaches, such as warning about the risks of doping, appropriate training, appropriate nutrition and an appropriate psychological approach.
Smart training equals performance

Published: April 2019

Abstract

Introduction: Training individualization is a key element for optimal sports performance and protection of the athlete’s health. The training program should be adjusted according to each athlete's characteristics and should be based on data obtained using proper evaluation. Cardiopulmonary exercise testing (CPET) is considered the gold standard for aerobic exercise capacity assessment and provides an increased quantity of information in regard to body reaction to effort, offering a complete perspective over the O2 transportation system and its utilization in metabolic processes.
The aim of this study was to highlight the importance of a scientific approach regarding the physical training, starting from junior level.

Methods: For a 3 years period (2013 - 2016) we followed the evolution of a professional cyclist (14 years old at baseline), in terms of cardiopulmonary parameters. During this period, he was tested 5 times and he followed a special training program adapted according the tests results. The CPET was performed in the laboratory using a stationary electronically braked cycle ergometer (Lode Corival, Netherland) and a breath by breath gas analyzer device (Cortex Metalyzer 3B, Germany).

Results: We observed an improvement trend in almost all parameters investigated during the 3 years evaluation period. Comparing post-season records from 2013 and 2016, we noticed an increase of 54% in maximal aerobic power and 50% in peak oxygen uptake at anaerobic threshold and an even greater increase (59%) of these parameters at maximal effort achieved during CPET. After these 3 years of training we observed a significant improvement of ventilatory efficiency and cardiac performance during exercise.

Conclusions: The study indicate that proper training adaptation according to data obtained using CPET, can bring an important progress in terms of performance.

Evaluation of posture in sports performance
Authors: Jurjiu Nicolae-Adrian , Pantea Corina 
Published: April 2019

Abstract
The aim of this paper was to study a number of 34 athletes practicing different kinds of sports activities, in order to determine whether they have developed a certain spine deficiency and if there is any association between the type of sports they practice and the postural changes they develop.

Methods: In this study we have enrolled 12 members of the men’s volleyball team of the “West University of Timisoara”, 9 members of the men’s football team ASU Politehnica Timișoara, and 13 members of the men’s basketball team BC SCM Timișoara. Postural analysis was carried out with the Zebris CMS-10 from the mechatronics department of the Politehinca University Timisoara, a device that determines the spatial coordinates of the spinous processes. From the obtained data we have established the angle of the spinal deviation both sagittal and frontal, in a similar manner as with the Cobb method.

Results: We have observed a reduction in the spinal curvature in volleyball players; 8 out of 12 had values under the normal range that can in time lead to a rigid spine. 7 players from the basketball team presented values out of the normal range for kyphosis and 8 of them for lordosis, while all except two of the team players present with a front plane deviation of the spine. From the evaluation of the football players from ASU Politehnica Timișoara we cannot generalize a deviation in the sagittal plane, but all of them present deviations in the frontal plane.

Conclusion: Professional athletes can also present postural changes determined by the positions they most frequently adopt depending on the type of sports they practice.

This study aims to discuss the learning and intruction which is an activity conducted by teachers and students. Learning is the process of changing a behavior and knowledge. Learning process becomes one system in intruction. The intruction system consists of several components that interact with each other, that is: teachers, students, learning objectives, materials, media, methods, and evaluation. The intruction can not be done well without any interaction between the learning components, then all components of learning must cooperate to make a efficient learning
