MODIFICATION AND APPLICATION OF STARCH IN NATURAL RUBBER LATEX COMPOSITES
Authors: Misman M. A. , Rashid Azura A. , Yahya Siti Rohana
Published: February 2018

This study presents a review of recent studies on starch-filled NR latex composites. Starch is a renewable source of material for fillers in NR latex compounding to obtain composites with multifunctional properties for selected applications. However, starch is a non-reinforcing filler due to its large particle size. The compatibility of NR and starch is another significant issue during the processing of starch-filled NR latex composites due to the nature of both materials. However, based on our research work, a fine dispersion of starch in the rubber matrix can improve the properties of NR latex composites. A good starch dispersion can be achieved through modifications, such as physical or chemical treatments. These treatments include the ball-milling process, ultrasonic process, use of coupling agents, esterification, etherification, and graft copolymerization. The various processing methods of these composites are discussed, specifically pre-vulcanization, latex co-coagulation, and in situ polymerization process. The successful modifications of either micro- or nano-starch will improve the compatibility with hydrophobic NR matrix, thereby increasing the mechanical properties of the resulting composites. The potential of starch as a biodegradable filler for NR latex and the interparticle interaction of starch-filled NR latex composites are also discussed.
VULCANIZATION SYSTEMS FOR RUBBER COMPOUNDS BASED ON IIR AND HALOGENATED IIR: AN OVERVIEW
Authors: Kruželák Ján , Hudec Ivan
Published: February 2018

The properties of IIR and halogenated IIRs, such as excellent steam and gas impermeability, heat aging stability, and oxygen and ozone resistance and increased chemical resistance, meet the demands of various industrial applications. However, due to the low level of unsaturation of IIR, the vulcanization rate is rather low and the degree of cross-linking is usually insufficient, causing IIR to be minimally co-vulcanized with unsaturated general-purpose rubbers. The low reactivity of IIR requires the consideration of a special composition of curing systems to provide the best possible rate and state of vulcanization. The type of curing system selected must also be a function of the composition of rubber formulations in which the IIR is used, and with respect to the final product's performance requirements. Therefore, the curing systems for IIR differ and can include standard sulfur systems, phenol-formaldehyde resins, or quinones. The incorporation of halogen (chlorine or bromine) atoms into the structure of IIR significantly increases the chemical reactivity, which can be subsequently reflected in a higher curing rate and the possibility to use some additional vulcanization systems such as metal oxides, diamines, or peroxide with co-agent. This study reviews the types and selection of applicable curing systems for IIR and its halogenated derivates.

This study aimed at identifying the level to which the administration at Al-Hussein Bin Tala(AHU) uses conflict management strategies and its relation to achievement motivation among its employees. To achieve the purposes of this study the researchers developed a scale that includes three parts: demographic information, (27) items measuring conflict management strategies and (20) items measuring achievement motivation. Validity and reliability were accredited the scale was applied to a sample of (149) academic administrative employees and only administrative employees who were randomly assigned.The results revealed that the means of conflict management strategies scale range from (2.634) to (3.369) at moderate level. Result also showed that there are no statistically significant differences at conflict management scale related to gender, job type and the number of years in administrative experience. However, the result revealed higher levels of achievement motivation means range from (4.651) to (4.013). Finally it was indicated that there was a significant positive but low relation between avoiding strategy and the achievement motivation while there was no significant relation between the use of the other strategies and achievement motivation. The study sample consisted from 149 employees at AHU. The sample consisted form academic/administrative employees and administrative employees, where academic/administrative have joint responsibilities: academic and administrative. The participants were selected using simple random sampling from the study population of 290 employees based on statistics personnel affair department for the academic year 2016/2017. The results showed that the means of the participants’ perceptions of the levels of utilization of the four conflict management strategies were moderate, ranged between (M = 2.63, SD=.72) and (M = 3.37, SD=.58). In addition, the results showed that there were no statistically significant differences at (α <0.05) in the participants’ means of perceptions of the levels of utilization of the four conflict management strategies based on their gender, job type, and number of years of administrative experience. The results showed that the means of the participants’ responses to the items of achievement motivation scale were high, ranged between (M = 4.01, SD=.84) and (M = 4.65, SD=.64).  Furthermore, the results showed that there was positive and weak correlation between means of the participants’ perceptions of their level of achievement motivation and participants’ means of perceptions of the levels of utilization of the avoiding strategy to resolve conflicts and the overall levels of utilization of the management strategies at AHU.

I denne artikkelen presenteres erfaringer og funn fra fire år med undervisning i emnet «Innføring i ingeniørfaglig yrkesutøvelse og arbeidsmetoder» ved Høgskulen på Vestlandet. Disse sees i sammenheng med det økende kravet om ex. phil. i all høyere utdanning. Våre ingeniørstudenter viste meget liten interesse for emnet ved oppstart i 2012, men ved å endre på pedagogikk og faglig tilnærming har studentene gradvis blitt mer interessert i dette dannelsesfaget. Skal en lykkes med å innføre ex. phil. i all høyere utdanning må man ta høyde for at de ulike studentgrupper har ulike preferanser og interesser.
Developing work placements in a discipline-oriented education
Authors: Velle Gaute , Hole Torstein Nielsen , Førland Oddfrid Kårstad , Simonelli Anne-Laure , Vandvik Vigdis
Published: February 2018

Education within higher education is often divided into discipline-oriented and professional programs. Professional programs prepare students for a specific profession and include relevant theoretical- and practical knowledge. Discipline-oriented programs emphasize theoretical knowledge and research within a specific discipline or field. Except for a career within research and higher education, discipline-oriented programs provide less obvious links to future careers. The transition from student life to working life may therefore be challenging. In this paper, we present and discuss the development and implementation of a work placement course as part of the disciplinary programs in biology at the University of Bergen. The course was developed to provide students with practical- and work- related skills and competences, inform about future careers and to foster motivation and learning. We have revised the course according to feedback from students, workplace hosts and our experience during the six semesters the course has been running. The work placement course is at the bachelor (BSc) level and consists of two main components; the work placement itself and the student’s own reporting of placement outcomes. For the placement, the students work 140 hours at a workplace as a biologist. The reporting consists of four open blog-posts, one written reflective essay and a final oral presentation. The course teachers also meet with the students and convey information on the roles of biology and biologists in today’s society through a Facebook group. Feedback from the students, hosts and course teachers point to a range of benefits from work practice courses in discipline- oriented study programs. Based on our experience, we provide guidance for developing such courses as part of discipline-oriented curricula.

Published: February 2018

El cormorán neotropical (Phalacrocorax brasilianus) es un ave acuática de amplia distribución que se encuentra usualmente en aguas claras poco profundas. La especie ocupa una amplia variedad de hábitats y ha sido reportada en varias localidades de Guatemala, en zonas costeras y del interior del país. El 15 de diciembre de 2016 observamos dos cormoranes en el río Motagua, Río Hondo, Zacapa, en el valle del Motagua, Guatemala. Esta observación, así como un reporte reciente de esta especie en Baja Verapaz, sugiere que la especie está colonizando localidades que, originalmente, tuvieron diferentes tipos de hábitat y que ahora constituyen una especie de monohábitat. Esta ampliación de la distribución local del cormorán puede tener diferentes implicaciones o al menos ofrecer algunas interpretaciones en términos de la conservación de la biodiversidad.

Authors: N Javzmaa , Sh Altantsetseg , S Shatar , A Amarjargal
Published: February 2018

Essential oils of aromatic and medicinal plants generally have a diverse range of activities because they possess many active constituents that work through a several modes of action. Artemisia, the largest genus of the family Asteraceae, has a number of effects against human and plant diseases. The main purpose of the present study was to investigate chemical compositions of essential oils of two Artemisia species, Artemisia palustris L and Artemisia sericea Weber ex Stechm from the Mongolian steppe zone using gas chromatography and gas chromatography-mass spectrometry. The essential oil of A.palustris was characterized by the presence of monoterpene hydrocarbons such as  trans-β-ocimene (59.1%), cis-β-ocimene (11.6%) and myrcene (7.1%), while the oil of A.sericea was dominated by the presence of three oxygenated monoterpenoids as 1,8-cineole (25.8%), borneol (22.5%) and camphor (18.8%) which are used for preparation of a fragrance and medicinal products.
Synthesis and electrocatalytic activity towards oxygen reduction reaction of gold-nanostars
Authors: G Oyunbileg , G Batnyagt , B Enkhsaruul , Takeguchi T
Published: February 2018

The oxygen reduction reaction (ORR) is a characteristic reaction which determines the performance of fuel cells which convert a chemical energy into an electrical energy. Aims of this study are to synthesize Au-based nanostars (AuNSs) and determine their preliminary electro-catalytic activities towards ORR by a rotating-disk electrode method in alkaline electrolyte. The images obtained from a scanning electron microscope (SEM) and a transmission electron microscope (TEM) analyses confirm the formation of the star-shaped nanoparticles. Among the investigated nanostar catalysts, an AuNS5 with smaller size and a few branches showed the higher electrocatalytic activity towards ORR than other catalysts with a bigger size. In addition, the electron numbers transferred for all the catalysts are approximately two. The present study results infer that the size of the Au-based nanostars may influence greatly on their catalytic activity. The present study results show that the further improvement is needed for Au-based nanostar catalysts towards the ORR reaction.
3D Scene Modeling And Understanding From Image Sequences
Authors: Tang Hao
Published: February 2018

A new method for 3D modeling is proposed, which generates a content-based 3D mosaic (CB3M) representation for long video sequences of 3D, dynamic urban scenes captured by a camera on a mobile platform. In the first phase, a set of parallel-perspective (pushbroom) mosaics with varying viewing directions is generated to capture both the 3D and dynamic aspects of the scene under the camera coverage. In the second phase, a unified patch-based stereo matching algorithm is applied to extract parametric representations of the color, structure and motion of the dynamic and/or 3D objects in urban scenes, where a lot of planar surfaces exist. Multiple pairs of stereo mosaics are used for facilitating reliable stereo matching, occlusion handling, accurate 3D reconstruction and robust moving target detection. The outcome of this phase is a CB3M representation, which is a highly compressed visual representation for a dynamic 3D scene, and has object contents of both 3D and motion information. In the third phase, a multi-layer based scene understanding algorithm is proposed, resulting in a planar surface model for higher-level object representations. Experimental results are given for both simulated and several different real video sequences of large-scale 3D scenes to show the accuracy and effectiveness of the representation. We also show the patch-based stereo matching algorithm and the CB3M representation can be generalized to 3D modeling with perspective views using either a single camera or a stereovision head on a ground mobile platform or a pedestrian. Applications of the proposed method include airborne or ground video surveillance, 3D urban scene modeling, traffic survey, transportation planning and the visual aid for perception and navigation of blind people.
Algorithms for selecting parameters of combination of acyclic adjacency graphs in the problem of texture image processing
Authors: Sang Dinh
Published: February 2018

Nowadays the great interest of researchers in the problem of processing the interrelated data arrays including images is retained. In the modern theory of machine learning, the problem of image processing is often viewed as a problem in the field of graph models. Image pixels constitute a unique array of interrelated elements. The interrelations between array elements are represented by an adjacency graph. The problem of image processing is often solved by minimizing Gibbs energy associated with corresponding adjacency graphs. The crucial disadvantage of Gibbs approach is that it requires empirical specifying of appropriate energy functions on cliques. In the present work, we investigate a simpler, but not less effective model, which is an expansion of the Markov chain theory. Our approach to image processing is based on the idea of replacing the arbitrary adjacency graphs by tree-like (acyclic in general) ones and linearly combining of acyclic Markov models in order to get the best quality of restoration of hidden classes. In this work, we propose algorithms for tuning combination of acyclic adjacency graphs.

The presented paper is concerned with the analysis of the current state of inclusion in general physical education (PE). Even though, students with physical disabilities form a majority and permanently growing group of individually included students, this topic is not yet well described. Th e survey took place in 2007 in elementary schools. A research sample consisted of 164 PE teachers who taught students with physical disabilities (164 boys, 90 girls). Out of the whole research sample 160 students were included to PE classes. Th e other students were released from PE based on a recommendation from their physicians. It is evident that the inclusion within the frame of PE represents a unique phenomenon enabling a complex development of the student’s personality. However, there are a number of important factors infl uencing success of inclusion, e.g. lack of fi nancial means, low family support, and lack of knowledgeable PE teachers in the fi eld of adapted physical education. Th ose crucial factors signifi cantly infl uence the process. An essential factor in the successful inclusion of students with disabilities to the system is the creation of appropriate conditions by the school (material, personal, spatial). Also the family has to undertake certain steps leading to a more eff ective cooperation. Inclusive PE should be based on a complex assessment of students. It should suit their individual needs and should be highly planned and systematic.

The paper deals with looking for potential indicators of correct technique of bounce concerning a tucked forward somersault on the base of relations between time characteristics of instantaneous forces in a vertical and horizontal plane in a realization phase of the bounce. Our test-group was created by 13 students of Faculty of Sport. We used statistical signifi cance of Spearman correlation coeffi cients p ≤ 0,05 as a method for judging whether or not a particular ratio of the impulses of forces in the vertical and horizontal plane represents a suitable indicator of correct technique of bounce. We assumed that some of the observed ratios will represent the potential indicator of correct technique of bounce. Th e hypothesis was confi rmed. Th e potential indicators of bounce are the following: variable 4 (time frame since vertical force reached its maximum value to the end of jump to total time of bounce), variable 6 (time frame since vertical force reached its maximum value to the end of bounce to the time frame from when horizontal force reached its maximum value to the end of bounce), variable 2 (time frame since vertical force reached its maximum value to the end of bounce).

Th e program follows the interest of the teenage generation and is based on modern methods from abroad. An experiement was conducted to verify the effi ciency of the new dance program. Th e aim of the experiment was to compare the level of dance skills improvement. 4-way ANCOVA was used to evaluate the experiment. Th e covariates were dance program, aft erschool activities, age, teacher, pre-test performance. Th e results of the research enriched the fi eld of dance education, especially the process of learning new dance skills. Th e new dance program improved the results of all music and motor skills and from the view point of development of specifi c dance skills it was considered very effi cient. Th e level of music skills varied according to the age of research subjects, which shows the importance of creating programs with adequate contents according to the students age. Our research showed the dance skills as three-dimensional with three latent factors: rhythmic, memory and motor. Th e results also pointed out the fact that aft er school activities focus on improvement of dance motor skills (dance technique) but neglect the music and rhythmic perception, which is the initiator of dance movement. Our results also confi rmed that dance skills can be improved by a short term dance program within the school P.E. lessons. Th e results of the research also showed unsignifi cant eff ectivity of recent dance motor programs at schools in development of dance skills. Th e results contributed to the scientifi c fi eld of dance education, especially the factor structure of dance skills.

This article looks at the evolution of structure teams in the highest Czech basketball league. The tracking period is since seasons 1998/99 to 2008/09. This research is based on content analysis of game statistics from particular games. The sample of players is classified into three groups (Czech players younger than twenty years, Czech players twenty years old and older, foreign players) and evaluates statistical characteristics by the comparative method. These include the number of players, minutes played, points scored and coefficient of usefulness. The results confirm the expected increase of the number of foreign players as well as continuously growing impact on the game. The impact is expressed as a coefficient of player’s utility. In contrast to this, the trend of participation and usefulness of Czech players younger than twenty years is shown to be diminishing. The hypotheses of our studies are therefore proven valid. The article refers to the change of the team constitution.

The objectification of strength speed abilities diagnostic is very important in the field of conditioning. The studies are mostly concentrated on activity of muscle groups, by EMG, in various ways to do bench press. The main aim of research was compare selected parameters of strength in two basic grip wide of press on horizontal bench. We measured the maximal mean power in total and in acceleration part of concentric phase of movement in increased diagnostic series in bench press. The results confirmed our the hypothesis, the peak mean power in total concentric phase was achieved by narrow grip with counter movement 509,9±87,2 W and with wide grip 477,06±86,7 W (p<0,01). In acceleration part of concentric phase was the peak of mean power achieved in a narrow grip with counter movement 692,9±137,8 W, although in wide grip only 652,2±122,5 W (p<0,05). We recommend to use narrow grip as a mean os special strength development especially in sports where kinematics of movement are similar for example bobsleigh, handball, karate, box, etc.

The objective of paper is to compare the exercise intensity during playing the active video game PlayDance on dancing pads with playing on crosses marked on the ground. All respondents were student of university, 21-26 years old, with minimum previous experiences with dancing pads. Our research was aimed on comparison the differences in HR between exercise on dancing pads and crosses marked on the ground with regard to 3 basic levels of difficulty. We also were comparing the levels of difficulty between themselves. The research confirmed expectation that the level of exercise intensity is lower on crosses against on dancing pads and also that the exercise intensity increases with the level of difficultness except shifting between level 2 and 3 on crosses. Majority of players answered in the questionnaire that they found playing the game on dancing pads more enjoyable and motivational than on crosses. Therefore, we cannot recommend playing PlayDance on crosses marked on the ground as separated activity without combination with the dancing pads, while it seems that there is lost the motivation for keeping the exercise intensity. We recommend playing PlayDance on dancing pads or using a combination of pads and crosses.

The research focused on the sport training issue of junior goalkeepers in football. It was a two-group, time-parallel pedagogical experiment in natural conditions of the training process. We surveyed the impact of experimental factor on the dynamics of changes in game performance of goalkeepers with using individual game performance evaluation and expertise method - individual game performance evaluation. The content of special training of goalkeeper was the experimental factor in our pedagogical experiment. The experimental factor appeared differently in experimental and control group. In the technical and tactical preparation it appeared with a different representation of the offensive and defensive activities of goalkeeper. We based composing the experimental factor on more than 100 analyzes of individual game performance of junior and senior goalkeepers in top events. The results obtained during research were analyzed and compared with the results of the control group. We conclude that the training program of experimental group with emphasis on offensive game activities had a statistically significant impact on individual game performance of goalkeepers in the match.

The contribution deals with the issues of judging the level and evolution trends of somatic and motor performance preconditions in tennis. In contemporary world tennis, there is an obvious tendency to the physically demanding game and that is why the diagnostics of the level of performance preconditions is an important part of the training process. The research intent was to perform a longitudinal observation of the level of somatic and motor preconditions in two female tennis players, who have reached a high international level of performance in their adult age, to evaluate evolution trends and to compare the found data with a population of female tennis players. The research had the character of a longitudinal study and the data were gathered using the test battery TENDIAG1 containing three somatic and six motor items. The results of both observed female players clearly show that the total point score in the test battery was above the boundary of the average level of the female tennis players’population. The results proved that the level of somatic and motor preconditions of both female players was mostly above average. The results confirm the importance of somatic, conditioning, and coordination preconditions for tennis.

The research was focused on analyzing balancing in handstand, as one of the fundamental physical structure sports gymnastics. With this research dealt many authors, but without application in practice.Its specificity is determined from the mechanical point of gravity height, the size of the support surface and the overall equilibrium position in which maintain stability. The aim of the project was to optimize the training of standing on their hands, depending on the strategy of maintaining a balance in this unstable static physical structure. For a comprehensive analysis of handstands is utilized synchronized 3D kinematic analysis, stabilomathric measuring and EMG, which we were reveal the inner essence of outer performance of technique. It was a case study and the tested person was a gymnast of student category and we focused on changes in the angle of the hip joint ("shoulder - hip - knee") and shoulder joint ("wrist - shoulder - hip") in connection with the muscle activity observed muscles and muscle groups. Now the application of this knowledge in practice, we can optimize the training, which in some cases lengthy.

Published: February 2018

Since the 90s of the twentieth century, the sports diagnostics have started applying principles of fuzzy logic, which offers a different quality approach to data analyses than the standard probability approach. The aim was to create a process for evaluating each test of the battery of tests TENDIAG1 on the principle of fuzzy theory. Based on similar published research and expert reviews we constructed membership functions for individual tests and proposed an algorithm to calculate the boundary points. Procedure for the construction of membership functions is demonstrated in the research data set of the tennis players aged 11-12 years (n = 187), specific evaluation of the results was performed at the sub-set of randomly selected tennis players (n = 25) of the set. For the final evaluation of the results of the test battery we used the method of aggregation of partial results. This procedure allows a finer resolution level of performance of individual players than the currently used threelevel standard. We are sure that in the future, more sophisticated methods of aggregation will be used, allowing to work with different weights of subtests.
