Authors: Morales Jose , Roman Vicenç , Yáñez Alexandre , Solana-Tramunt Mònica , Álamo Juan , Fíguls Antón
Published: April 2019

This study compares and describes relationships among stress-recovery indices, the heart rate variability index, and the Cooper and Yo-Yo IR1 tests among female soccer players during the last six weeks of the competitive season. Sixteen female soccer players engaged in a pre-test of all of the variables. After having their training monitored for six weeks, a post-test was administered. The results revealed significant (p < 0.05) differences in the specific stress-recovery scales of the RESTQ-sport and in the frequency-domain variables of the HRV, although there were no significant differences in the general stress or general recovery scales. The Yo-Yo IR1 test, the Cooper test scores, and the means of the time-domain HRV variables did not exhibit any significant differences between the pre- and the post-test. The RMSSD variations exhibited very large and large correlations with the performance test and the RESTQ-sport variables, respectively. The variations in the HRV frequency-domain variables exhibited significant moderate and large correlations among the variations of the RESTQ-sport scales. Monitoring athletes at the end of the season may reveal contradictions between some variables. To help with the interpretation of these scales, some external aspects, such as athlete strain and monotony of training, should be considered.

The purpose of this study was to analyze the day-to-day variance of a typical weekly external training workload of two professional soccer teams from different countries. Twenty-nine players from two professional teams from Portugal and the Netherlands participated in this study. The players’ external load was monitored for 7 weeks, by means of portable GPS devices (10 Hz, JOHAN, Noordwijk, Netherlands). Results revealed that match day -1 (MD-1), i.e. the training day before a match, had significantly (p = 0.001) less training volume (4584.50 m) than the other days. MD-5 (training five days before a match), MD-4 (four days before a match) and MD-3 (three days before a match) were the most intense (390.83, 176.90 and 247.32 m of sprinting distance, respectively) and with large volume (7062.66, 6077.30 and 6919.49 m, respectively). Interestingly, significant differences were found between clubs of different countries (p < 0.05) with the Portuguese team showing significantly higher intensity (sprinting distance) and volume (total distance) in all days with exception of MD-1 than the Dutch team. The results of this study possibly allow for the identification of different training workloads and tapering strategies between countries in relation to volume and intensity. It should be noted, however, that both clubs used a significant tapering phase in the last two days before the competition in an attempt to reduce residual fatigue accumulation.

Authors: Kubayi Alliance , Toriola Abel
Published: April 2019

Although the influence of ball possession in soccer has been well studied in other leagues, such information is sparse concerning the South African Premier Soccer League (PSL). The purpose of this study was to assess the impact of situational variables on ball possession in the PSL. Thirty-two matches played during the 2016–2017 PSL season were analysed using a multiple-camera match analysis system (InStat®). Three situational variables (match outcome, match location, and quality of opposition) and team performance variables (percentage of ball possession, ball possession <5 s, ball possession 5–15 s, ball possession 15–45 s, and ball possession >45 s) were examined. The results showed that losing teams had the highest ball possession (52.35 ± 5.90%) compared to winning (47.65 ± 5.90%) and drawing (50.00 ± 9.98%) teams. Playing away significantly (p < 0.05) decreased ball possession by 5.21% compared to playing at home. Playing against weak opposition was associated with increased ball possession by 4.09%. Conclusively, soccer coaches should be aware of the potential role of situational variables in determining successful team performance in a league season.

Published: April 2019

The objective of this study was to carry out a detailed quantitative analysis of the very high intensity runs during actual play in the 2013-2014 Spanish First Division, at a general level and according to the specific playing position and half. 380 matches of the Spanish First Division in the 2013 - 2014 season were monitored using the Mediacoach video motion analysis tool. Total distance, very high intensity (above 21 km/h) running distance and the number of runs at very high intensity of 230 players from 20 teams in the Spanish First Division were analysed. The main findings of the study were that the performance indicators at very high intensities decreased from the first half to the second half for all outfield players (covered distance: 4694 ± 538 m vs 4485 ± 437 m, sprint distance: 256 ± 72 m vs 239 ± 67 m, number of sprints: 14.3 ± 3.5 vs 13.2 ± 3.1), except the central defenders (sprint distance: 166 ± 37 vs 166 ± 40 m, number of sprints: 10.0 ± 2.1 vs 9.8 ± 3.8). Secondly, although wide defenders (9759 ± 665 m) and central midfielders (9776 ± 942 m) covered the most distance during matches, it were the wide defenders (30 ± 5), centre-forwards (28 ± 7) and wide midfielders (31 ± 8) who performed the most runs at very high intensity. Consequently, the distance they ran at these very high intensity runs followed the same pattern. Such results enable general and specific profiles by demarcation to be established based on the demands of the game at high-level competitive play.

Published: April 2019

The purpose of the study was to examine how various playing positions affected the number of (and percentage breakdowns for) physical and technical activities of soccer players in the Germany’s Bundesliga. A further objective was to identify and present features distinguishing between the activities of players within the Defender, Midfielder and Forward formations. The study sample comprised 4426 individual match observations of 473 soccer players competing in the Bundesliga during the 2016/2017 domestic season. Data from the Impire AG motion analysis system, and the so-called ”heat maps” it supplies, revealed areas in which players spent most time during a match, with 22 different playing positions on the pitch identified in consequence. Players in the formation comprising Defenders did not differ significantly in relation to the number of accelerations, the number of shots or the percentage of duels won. Furthermore, there were no significant differences among Midfielders in regard to total distance covered, mean running speed, the number of accelerations, the number of duels and the percentage of duels won. Likewise, Forwards did not differ in distances covered at ≥24 km/h, average running speed, the number of sprints, the number of shots, the proportion of on-target passes, the number of duels, or the percentage share of duels won. Irrespective of the formation or position on the pitch, today’s game of soccer also pays great importance to the number of accelerations, as well as the number of duels engaged in, and their effectiveness.
Body Height and Swimming Performance in 50 and 100 m Freestyle Olympic and World Championship Swimming Events: 1908 - 2016
Authors: Mazzilli Facundo
Published: April 2019

There are scattered data showing an increase in the height of Olympic and World Championships swimmers. To identify a possible historical trend, a study of the height of 50 and 100 m freestyle medalists at the Olympic Games and the World Championships between 1908 and 2016 was undertaken. 370 swimmers (186 men and 184 women) were studied. A progressive increase in the height of men’s medalists (r = 0.49, p < 0.001) was detected. With regard to women’s medalists, an increase (r = 0.383, p < 0.01) was also found. To provide a sort of confirmation of this trend, a separate analysis of swimmers achieving new official swimming records, not included in the initial design of the study, was undertaken and a similar and also significant trend was seen in this case in both male and female athletes. This study confirms and greatly expands the observation of other authors, and raises the question of whether the increase in the stature of elite swimmers is simply a reflection of the increase in height of the general population or whether other factors, such as a possible role of training, should be considered. The ethical aspects of an early selection of swimmers perhaps based on the genetic profile of youngsters deserves careful consideration.

Published: April 2019

The main objective of this study was to provide an extensive isokinetic profile of the hip joint in youth soccer players, where the literature is limited. Additionally, this study investigated the effect of age on isokinetic peak torque values of hip abductor and adductor muscles and on reciprocal muscle group torque ratios in youth soccer players at different angular velocities (30 vs. 90o/s) and muscle actions (concentric vs. eccentric). Sixty young elite male soccer players were assigned into three equal groups (n = 20): children, young adolescents and older adolescents, and performed five maximal concentric and eccentric hip-abductions and adductions at 30o/s and 90o/s. The results showed a significant increase (p < 0.05) in peak torque values from childhood to adolescence, with the exception of young adolescents vs. older adolescents where no differences were observed. The reciprocal ratios were not affected by age, but improved with an increase in angular velocity with the exception of the CON/ECC ratio that was higher at 30o/s. The data presented in this study provide an extensive isokinetic profile of hip abductor and adductor muscle strength in youth soccer players to assist both coaches and sports medicine professionals in strength monitoring and training.
Proposing an Index to Determine the Contract Level at the Pre-Contract Stage from the Viewpoint of Health, Safety and Environment (HSE)
Authors: Mapar Mahsa , Jafari Mohammad Javad , Mansouri Nabi-allah , Maheronnaghsh Sara
Published: April 2019

The level of contractor’s HSE is a major concern in outsourcing of the works for large organizations. In each tender a rational level of HSE holding by the contractors is recommended to reduce the project costs. By investigating the classification procedure of the contracts available in reliable manuals and models at international level, 6 main criteria were selected for determining the contract level from the viewpoint of HSE. Also, an indicator, called "contract separation" was proposed by weighting the criteria. Initial weight of the main criteria along with their scoring in this indicator was determined by applying sub-criteria characteristics, namely "specialized workforce", "man-day required for meeting the criteria", "required technology", and "impact of criterion on planning the next steps of the contract". Then, by preparing a questionnaire and applying the experts' opinion, the final weight of the criteria was specified, based on which all the contracts of Shahid Tondgouyan Oil Refinery Company in Tehran were divided into four levels, namely (1) advanced, (2) moderate, (3) basic, and (4) exempted from the initial HSE assessment. Results of the present study showed that the operational risk level had the highest impact percentage on determining the level of contract compared with other criteria, which indicates that regardless of other criteria, in case the level of contract risk is high, some special HSE measures should be planned for that contract according to the advanced contracts. Also, cost of the contract had the lowest weight; although cost of the contract is one of the most effective criteria in the contract classification, it cannot by itself represent the magnitude of the contract from the HSE perspective and its impact must be considered along with other criteria associated with HSE in order to determine the contract level.

Authors: Bustos Lidia Denisse , Guedes Joana , Torres Costa Jose
Published: April 2019

Background: The resulting interaction between occupational stress and individual susceptibility to illness demands careful management. This represents a dual challenge to organizations responsible for the well-being of personnel who engage in strenuous physical exertion, imposing requirements to be vigilant for, or even curtail, situations that may result in high physiological strain in healthy personnel and also to identify and protect vulnerable individuals. The emergence of wearable physiological and medical monitoring technologies could prove advantageous in this regard.

Objectives: A systematic review is proposed to summarize current progress in the development of physiological monitoring systems for occupational applications. Thus, adhering with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) Statement, this systematic review protocol aims to present adequate guidelines to develop research that can provide appropriate results to the sought objective.

Data sources: Five databases will be accessed (SCOPUS, PubMed, Science Direct, Academic Search Complete and Web of Science) and a total of 12 keywords will be combined.

Study eligibility and criteria: Working-age study participants will be included. Assessment procedures will be considered when they do not interfere with normal tasks development and involve harmless procedures for participants.

Study appraisal and synthesis methods: Two authors will independently screen titles and abstracts against the eligibility criteria at first, and full-texts of potentially eligible records at a second phase, followed by extraction of data from qualifying studies. Two review authors will also assess the risk of bias and the quality of evidence, taking as a reference the Cochrane Collaboration’s Tool.

An Authorisation Policy Management Model in Federations
Authors: Cham Vu Ngoc , Anh Nguyen Tuan
Published: April 2019

A federation is usually an alliance of organisations where users from one organisation are trusted to access resources in another organisation. The membership of federations is diverse and continually changing. Federations require distributed and dynamic security policy management to meet these challenges. We propose an authorisation policy management model, FABACD, which simplifies the management of collaborations between organisations. It allows distributed and trusted administrators to adjust the authorisation policies in a resource holding organisation, whilst ensuring that the latter remains in ultimate control. The net result is that a resource’s authorisation system is able to use user credentials built from preexisting attributes issued by any participating organisation, in order to determine a user’s access rights to the various resources, without requiring credentials to be issued that are based on federation specific attributes. The model significantly simplifies the authorisation management process for the resource holding organisation.

On Locally Strongest Assumption Generation Method for Component-Based Software Verification
Authors: Tran Hoang-Viet , Hung Pham Ngoc
Published: April 2019

Assume-guarantee reasoning, a well-known approach in component-based software (CBS) verification, is infact a language containment problem whose computational cost depends on the sizes of languages of the softwarecomponents under checking and the assumption to be generated. Therefore, the smaller language assumptions,the more computational cost we can reduce in software verification. Moreover, strong assumptions are moreimportant in CBS verification in the context of software evolution because they can be reused many times in theverification process. For this reason, this paper presents a method for generating locally strongest assumptions withlocally smallest languages during CBS verification. The key idea of this method is to create a variant techniquefor answering membership queries of the Teacher when responding to the Learner in the L–based assumptionlearning process. This variant technique is then integrated into an algorithm in order to generate locally strongestassumptions. These assumptions will effectively reduce the computational cost when verifying CBS, especiallyfor large–scale and evolving ones. The correctness proof, experimental results, and some discussions about theproposed method are also presented.Keywords: Assume-guarantee reasoning, Model checking, Component-based software verification, Locallystrongest assumptions, Locally smallest language assumptions.
Simulation-based Short-term Model Predictive Control for HVAC Systems of Residential Houses
Authors: Nguyễn Sơn Hoài , Tan Yasuo
Published: April 2019

In this paper, we propose a simple model predictive control (MPC) scheme for Heating, ventilation, and air conditioning (HVAC) systems in residential houses. Our control scheme utilizes fitted thermal simulation to achieve precise prediction of room temperature and energy consumption in each prediction period. The set points of HVAC systems are selected to minimize the amount of energy consumption while maintaining room temperature within a desirable range to satisfy user comfort. Our control system is simple enough to implement in residential houses and is more efficient comparing with rule-based control methods.
Experimental and Computational Study on the Inclusion Complexes of β-Cyclodextrin with Selected Food Phenolic Compounds
Authors: Simsek Tuba , Simsek Senay , Mayer Christian , Rasulev Bakhtiyor
Published: April 2019

A number of phenolic compounds, including caffeic acid, trans-ferulic acid and p-coumaric acid that are commonly found in food products are beneficial for human health. Cyclodextrins can form inclusion complexes with various organic compounds in which the physiochemical properties of the included organic molecules are changed. In this study, three phenolic compounds with β-cyclodextrin as inclusion complexes were studied. The complexes were characterized by various analytical methods, including NMR-, FT-IR spectroscopy, mass spectrometry, differential scanning calorimetry and scanning electron microscopy. Results showed that the phenolic compounds used in this study were able to form inclusion complexes in the hydrophobic cavity of β-cyclodextrin by non-covalent bonds. Their physicochemical properties were changed due to the complex formation. In addition, a computational study was performed to find factors that were responsible for binding forces between flavors and β-cyclodextrin. The quantum-mechanical calculations supported the results obtained from experimental studies. Thus, DHf for the complex of p-coumaric acid and b-cyclodextrin has been found as -11.72 kcal/mol, which was about 3 kcal/mol more stable than for inclusion complexes of other flavors. A HOMO-LUMO gap for the complex of p-coumaric acid and b-cyclodextrin had the largest value (8.19 eV) in comparison to other complexes, which was an indication of higher stability complex.
Hollow zeolite microspheres as a nest for enzymes: a new route to hybrid heterogeneous catalysts for chemo-enzymatic cascade reactions
Authors: Smeets Valentin , Baaziz Walid , Ersen Ovidiu , Gaigneaux Eric M. , Boissière Cédric , Sanchez Clément , Debecker Damien
Published: April 2019

Integrating enzymatic and heterogeneous catalysis can pave the way to new and performing cascade chemical processes. In this perspective, the preparation of bifunctional structures combining both an active inorganic catalyst and an enzyme is a key. However, such combinations are not straightforward, for example in the case of zeolite catalysts for which enzyme immobilization would be restricted to the external surface. We overcame this challenge by developing a new kind of hybrid catalysts based on hollow zeolite microspheres. The method leverages on the aerosol-assisted assembly of TS-1 nanocrystals to form hollow zeolite microspheres with tailored hierarchical texture and high epoxidation activity in water. The latter spheres were subsequently loaded with glucose oxidase enzymes which were then cross-linked to secure their entrapment. This controlled design allows to combine all the decisive features of the zeolite with a high enzyme loading. A chemo-enzymatic reaction is demonstrated, where the structured zeolite microsphere is used both as a nest for the enzyme and as an efficient inorganic heterogeneous catalyst. The enzyme ensures the in situ production of H2O2 subsequently utilized by the zeolite for the epoxidation of allylic alcohol. We anticipate our method will open up new perspectives in the field of hybrid catalysis. Starting from various catalytic nano-building blocks, hollow microspheres with open entry ways could be prepared using the aerosol process and could be used as vessels for enzymes or even multi-enzymatic systems, thereby giving access to a multitude of new heterogeneous chemo-biocatalysts.

New Class of Electrophiles in Palladium/Norbornene Cooperative Catalysis: Sulfenamide-Enabled Ortho Thiolation of Aryl Iodides
Authors: Li Renhe , Zhou Yun , Yoon Ki-Young , Dong Zhe , Dong Guangbin
Published: April 2019

To expand the synthetic platform of the palladium-norbornene cooperative catalysis, here we report a general ortho thiolation of aryl and heteroaryl iodides using sulfenamides as a new class of electrophiles. The sulfenamides derived from a ε-tbutyl-lactam were found most efficient to introduce various aryl and methyl sulfur groups at the arene ortho position. The ipso functionalization is achieved through Heck or Suzuki termination. This reaction also provides a convenient access to the corresponding aryl sulfoxides and sulfones via selective oxidation of the ortho thiolation products.
Assessing the Role of Inter-Molecular Interactions in a Perylene-Based Nanowire Using First-Principles Many-Body Perturbation Theory
Authors: Huang Tianlun , Lewis D. Kirk , Sharifzadeh Sahar
Published: April 2019

We present a first-principles many-body perturbation theory study of the role of inter-molecular coupling on the optoelectronic properties of a one-dimensional p-stacked nanowire composed of perylene-3,4,9,10-tetracarboxylic diimide (PTCDI) molecules on a DNA-like backbone. We determine that strong inter-molecular electronic coupling results in large bandwidths and low carrier effective masses, suggesting a high electron mobility material. Additionally, by including the role of finite temperature phonons on optical absorption via a newly presented approach, we predict that the optical absorption spectrum at room temperature is significantly altered from room temperature due to allowed indirect transitions, while the exciton delocalization and binding energy, a measure of inter-molecular electronic interactions, remains constant. Overall, our studies indicate that strong inter-molecular coupling can dominate the optoelectronic properties of π-conjugated 1D systems even at room temperature.

The authors summarized the extensive experience of reconstruction of buildings taking into account the superstructure. A visual full-scale inspection of the actual technical condition of the main bearing and enclosing structures of a non-residential one-storey building was carried out. The possibility of superstructure on the floor of the building using lightweight structural elements of high rigidity is considered.

According to the results of the survey, an assessment of the technical condition of the structures is given. The General satisfactory condition of the foundations, walls, internal supports, building covering was revealed. Unacceptable deflections of plates, cracks in the plates and between them are not fixed. However, in the wall at row G has haphazardly small cracks on external verst masonry, which appeared likely to result from the soaking of the masonry from leaks from the roof and changes in temperature and humidity. At the moment, the cracks have stabilized, the leaks have been eliminated.

The calculations of the foundations of the test conditions of the stress under the foot and stress check given add-in. Conclusions and recommendations are formulated. For the wall on the axis G in the process of construction and operation must be monitored. In case of activation of development of constructive cracks to solve a question of possible strengthening.

Develop recommendations for the use of polymer-concrete bending structures is impossible without the creation or optimization of existing methods of calculation, this is especially true for bending elements that use multi-level reinforcement. Для применения (especially under the influence of aggressive environment) for use as a material for the manufacture of bending structures, we offer rubber concrete. – polymer-concrete, which is characterized by high strength characteristics. It is important to note that the composition of fibrorubcon used industrial waste such as fly ash and steel cord. Beams made from cauton and fibrocahuton were tested for pure bending - the most characteristic form of loading in the study of such elements. As a result of the theoretical studies of polymer concrete beams, the prerequisites were established for the calculation of the first group of limit states of rubcon beams and the method for calculating fibrorubcon beams was optimized. It was determined that fiber reinforcement with a percentage of reinforcement by mass of the rubcon element equal to 2.5% corresponds to the work of rod longitudinal reinforcement with a value of μ = 0.34%.
