Published: June 2020

Abstract
The paper presents a review of the suspension solutions used on the street vehicle up to the now a days, finalising with presentation of their damping characteristics and with evaluation of their advantages or disadvantages. Long time the suspension systems have been dominated by the classic passive suspensions realized with metallic springs, shock absorbers with constant damping coefficients and anti-roll bars, excepting some luxury and sport cars using semi-active and active suspensions. There are presented some semi-active suspension solutions with continuous or discontinuous damping characteristics adjustment and the evolution of the Citroen and other active suspensions. All of them improve in some matter the performances but all of them have not ability to recuperate energy and has auxiliary energy consumption so last period the electromagnetically shock absorbers are researched, the paper presenting some of them. The paper also presents magneto rheological MR damper, solutions for adjustable passive shock absorbers and solutions for passive shock absorbers with variable damping coefficient with the stroke, e.g. Monroe Sensa Trac, Citroën Solution and VZN solution, with their damping characteristics and performances.

Published: June 2020

Abstract
The aim of the research was to determine the effect of polyester-glass recyclate on the deflection of composite samples subjected to three-point bending. The polyester-glass recyclate was obtained from the part of the ship’s hull made of polyester-glass composite, constituting scrap metal. The pieces of scrap were pre-fragmented and then processed into a prepared stand for this purpose. Such a fragmented recycling will be used to make composites with different scrap / recycled content. For this purpose, research materials were made using the vacuum bag method with the percentage of 0%, 10% and 20% recyclate) as well as various granulation (i.e. 1.2 mm and 3.0 mm). The research material consisted of rectangular plates with a thickness corresponding to the thickness of the samples. The samples for testing were made by water cutting. The tests were carried out on a suitably prepared stand, which was made of a universal Zwick Roell testing machine and three-point bending handles and a dial indicator. The spacing of the supports has been determined in accordance with the binding standard for three-point bending. Obtained results from tests, i.e. strain, stress, deflection, deformation allowed analysing the impact of recyclate on bending strength and defining the deflection arrow. Based on the results obtained from three-point bending, it can be concluded that the polyester-glass recycling has an influence on the decrease of strength, stress and deflections of the tested composites.
An Influence of Correction of the Ignition Advance Angle on the Combustion Process in SI Engine Fuelled by LPG with the Addition of DME
Authors: Kubica Grzegorz , Marzec Paweł 
Published: June 2020

Abstract
The paper presents the results of tests of the SI engine fuelled by LPG with the addition of DME in the form of a mixture of gaseous fuels. Experimental tests were carried out on a chassis dynamometer in the full range of engine loads, at a fixed rotational speed: 2000, 2500 and 3000 rpm. The use of dimethyl ether (DME) as a fuel component makes it possible to exploit its important advantages. DME can be produced as a renewable fuel, which is important from the point of view of ecology. Another important fact is the presence of oxygen in this fuel, which has a positive effect on the engine volumetric efficiency. During the tests, the ignition timing was also adjusted due to the very good DME flammability. Two additional correction levels were applied, increasing the ignition advance by 3 and 6 CA degrees, compared to the factory settings of the driver. The analysis of the obtained results allowed determining the dependence of the basic engine parameters, in the function of the correction of ignition advance angle. In the summary, attention was also paid to the possibility of determining corrected maps of the ignition advance angle taking into account the variable proportions of fuel components.
Attitudes of teachers in the Arab schools in Israel towards integration of students with special needs
Authors: Majadley Enas 
Published: June 2020

Summary
The program for the integration of children with special needs in the regular educational frameworks supports and encourages the integration of children with a variety of special needs, temporary or ongoing, within the context of regular education, and sees integration as both a goal and value. The integration program is operated through a training and treatment system in the educational frameworks, which were formulated according to the special needs of those students. With the increase in the trend towards integration in Israel and the expectation that this trend will grow in the future, it is essential to continue to explore teachers’ perceptions and attitudes regarding integration as well as their needs for training and continuing education. The Arab education system in general and the issue of caring for children with special needs in school, in particular, are at huge gaps. The purpose of this paper is to review the literature on mainstream teachers’ attitudes towards integration and, more recently, inclusion and to show the need of design research on attitudes of teachers in schools in Arab society in Israel towards the integration of students with special needs into regular classes.

Authors: Korzeniecka-Bondar Alicja 
Published: June 2020

SummarySchool is a complex system, inseparable from the specific context of here and now. Each day involves immersing in the course of particular events which are the result of multiple interactions at school. Time is what binds all the events taking place at school, and the category of time makes multi-level and multi-aspect analysis of school reality possible. The aim of the article is to reflect on the author’s own practice of phenomenographic studies of daily school time, to show the doubts occurring as part of the studies and to present the decisions taken. The text is the analysis of key elements of planning the studies, carrying them out and analyzing the results.
On the New-Old Political Concepts: Re-Conceptualizing and Expanding the Views in Studying Politics Following the Impact of Globalization
Authors: Latifi Veton 
Published: June 2020

Abstract
The article deals with the differences of pre-global and post-global conceptualizations in political sciences. It investigates the functions of political concepts under the changes globalization caused to political systems, culture and ideology. The paper does not engage with the methodological debates on political concepts, or question the undeniable importance of certain political concepts, but rather it addresses some of the principal concepts for which globalization may be a useful concept with regard to their similarities and differences with the Cold War era.
Despite the variety of political concepts as a result of various development phases of society, models of governance and ideological impact to the political processes along centuries, the concepts of power and authority seem to be among those that have survived in terms of the consistency of their relevance. However, the conception of politics through power, authority and leadership has been re-dimensioned significantly under the post-global era. By contrast, although the concept of sovereignty has been one of the initial concepts in the landscape of contemporary politics for many centuries back, following the effects of globalization, it has reduced its relevance significantly. In this view, as a consequence, the article discusses as well as the reconfiguration of the concept of state in a post-global era marked by a period of advancing causes—both trans-border and transnational causes—promoted by post-sovereignty states.
Under these circumstances the traditional debate regarding conflict versus cooperation in politics is one of the areas remaining within a status quo dimension in the dioptric view of both pre-global and post-global conceptualizations. With a contrastive methodological approach, the article as well analyzes the development and meaning of the concepts of political equality, justice and liberty as indispensable concepts in modern post-global political processes.
A Case-Control Study of Skin Microbiome in Patients with Lamellar Ichthyosis
Authors: Singh Mehak , Pawar Manoj 
Published: June 2020

Abstract

Introduction: Lamellar ichthyosis is a genetic disorder of keratinization and the frequent skin infections in these patients may be a result of change in normal skin flora acting in addendum to breach in the physical barrier. Material and Methods: A comparative retrospective study was performed in patients with lamellar ichthyosis and age/ sex controlled matched patients attending the dermatology IPD/OPD with positive skin swab results from July 1st 2015 to June 31st 2016. The two groups were then compared in terms of bacterial culture results. Results: The mean gestational age of the study subjects at birth was 35.56 weeks (range: 30–39 weeks). The study sample consisted of 6 males and 3 females in LI group and 12 males and 6 females in the control group. Methicillin resistant Staphylococcusaureus (MRSA) was exclusively seen in LI patients, and Gram negative rods, Fusobacterium and Candida were found more in the LI patients than in the control group. The Bacteroidetes to Firmicutes ratio, lipophilic diphtheroids, Propionibacterium acnes, Fusobacterium and Micrococci were present more in the control group than in the LI patients. Conclusion: By knowing this microbiota, undue reliance on antibiotics can be reduced as these microorganisms may form normal commensals for the given micro environment. Furthermore, these organisms may be responsible for perpetuating the disease process by compounding the genetic keratinocyte barrier. What is known: Frequent skin infections are not uncommon in patients of lamellar ichthyosis. What is new:
Methicillin resistant Staphylococcus aureus (MRSA) are commonly present in LI patients, and Gram negative rods, Fusobacterium and Candida are commoner in the LI patients than in the control group of patients.

Abstract

Introduction. Melasma is a common skin pigmentation disorder affecting a patient’s life psychologically and socially. Topical medications or lasers can have temporary and limited therapeutic effects on melasma. Material and Methods. This study is a prospective clinical trial comparing therapeutic effects of oral Tranexamic acid (TXA) and topical Hydroquinone (HQ) cream. A total number of 69 patients were examined. During the study, 10 patients failed to appear for the follow-up and 59 of them completed the trial. The patients were also divided randomly into two groups. Group A received TXA capsule 250 mg every 12 hours and group B received 4% topical HQ cream day and night. The patients from both groups were treated for 3 months. Melasma Area and Severity Index (MASI) scores were then calculated at the baseline, 4 weeks, and 12 weeks into the treatment and 3 months after the end of intervention. Results. MASI baseline, 4 weeks,12 weeks, and 24 weeks in TXA group were 21.66, 13.69, 9.10, 9.24; respectively. Reduction of MASI between baseline and 4 weeks was statistically significant. Such a decreasing trend in MASI scores between baseline and 12 weeks was also reported as statistically significant (p=0.001). In the HQ group, MASI baseline,4 weeks, 12 weeks, and 24 weeks were 21.46, 13.57, 10.93, 11.20; respectively. Reduction of MASI scores between baseline and 4 weeks was statistically significant. Moreover, a decline in MASI scores was observed between baseline and 12 weeks that was statistically significant (p=0.001). Considering both groups MASI scores were reduced but the difference between two study groups was not statistically significant (p=0.98). Conclusion. The efficacy of TXA and HQ was the same and both could significantly reduce MASI scores.

Published: June 2020

Abstract

Introduction: In the last decade in Romania, following the international trend, the interest for combat martial arts sports increased among the young generation. From all the contact sports, kickboxing was one of the most accessed athletic disciplines by both amateurs and professional athletes due to all the benefits of the complex training sessions.

Aim: The aim of the study was to analyze the differences between professional and non-professional males concerning the evolution of food habits and performance improvement when they follow the same training programme.

Results: Data analysis reveals an increase of physical performance in all performed tests. A significant improvement has been shown for both professional and non-professional athletes after 8 weeks of specific training. In the non-professional athletes group, the improvement of physical performance was even greater than in the professional group. Data analysis according to the age group revealed that in the case of the mature athletes the physical performance progress showed a lower augmentation than in the young ones, but the level of performance was at higher values than the performance of the young ones. In terms of nutrition, both groups need an improvement of their dietary habits, even if the professional ones revealed a better nutritional approach than the non-professional participants.

Conclusion: The results of this pilot study indicate that an integrative approach of a martial art athlete training is important in order to develop sports elites. The long term training programmes combined with proper nutrition are the key factors of the strategy for achieving greatness. Further studies are necessary in order to set the best physical and metabolic parameters in order to create the framework for a long term training strategy.
Study regarding the development of the front crawl and backstroke swimming techniques in children aged 7-10
Authors: Pîrjol Dan Ionuţ , Răsădean Marcel 
Published: June 2020

Abstract

Background: The biggest advantage of swimming is that the muscles and joints can move without the need to bear weight, thus the tension is limited which reduces most risks of injury. The water environment allows freedom of movement and exercise choices that are impossible on land.

Aim: The objective of our study is to test the hypothesis that the execution of a well designed training plan will result into the improvement of the technique and swimming speed in the front crawl and backstroke styles for the participants.

Methods: 16 children have been selected, 10 boys and 6 girls. Their mean age (8.4±0.96) is between 7 and 10. We chose 5 specific tests in order to evaluate our hypothesis.

Results: The final tests demonstrate that both performance and technique have been considerably improved as a result of the training plan.

Conclusion: After a well designed training plan for a period of 3 months, the group of children experienced a positive change in the quality of their motor skills associated with swimming which improved their technique and performance.

Authors: Gall Denisa-Laura , Vutan Ana-Maria , Niţă Andreea , Vutan Călin 
Published: June 2020

Abstract
Fractures of the proximal humerus account for 4% to 5% cases out of all fractures, and about 85% of them are minimally displaced. The purpose of the study was to observe the effectiveness of physiotherapeutic methods used in the proximal fractures of the humerus. Material and method: the research was performed on a group of 13 patients who have been orthopedically treated for fractures at the proximal end of the humerus. Five subjects followed the TECAR therapy and physical exercise, and eight subjects followed classical physiotherapy and physical exercise. The evaluations have been performed at the beginning of the recovery, after 14 days, after 28 days and after 42 days of treatment. Pain intensity (VAS score), joint amplitude (goniometry), muscle strength and functionality (the PENN questionnaire) were assessed in all patients. The results of the evaluations showed a decrease in pain, after the first 14 days, especially for the patients who underwent the Tecar therapy. Also, the results showed that the patients with surgical neck fractures had the best evolution in cases of goniometry evaluation, compared to the rest of the patients. In conclusion, physical therapies for proximal humerus fractures play an important role in the recovery and reintegration of the patients into family and at work.
Evaluation of the ventilometric parameters of two football teams in different leagues
Authors: Arnăutu Gabriel , Datcu Remus 
Published: June 2020

Abstract

Introduction: Spirometry testing is a physiological test measuring lung volume and flows. Compared to the other components of the respiratory system, training does not result into significant improvements as for the increase of the expiratory flow. The assessment of the respiratory function may indicate certain disorders of the bronchi and of the lungs, but, on the other hand, it offers little information on the aerobic capacity of the individuals or the effects of physical exercises.

Aim: The purpose of this research was to study the respiratory volumes in two football teams that are part of two different leagues (2nd league, and 5th league, respectively), and to compare these results with the ones at the international level.

Materials and methods: We included in this research two football teams in two different leagues (2nd league, and 5th league, respectively) and, from each team, we chose the players with the highest number of minutes spent playing throughout the championship return phase. In order to perform spirometry, we used a portable spirometer (Spirotube Spirometer, PC Spirometer). The prediction method used by the spirometer software was the one presented by the European Respiratory Society and Kudson.

Results: By comparing the environments of the two groups we can see that, in terms of height and weight, the two samples present close values. According to the results recorded with the help of the spirometer, the value of the forced vital capacity (FVC = 4.50) represents 98% of the normal level, and the Expiratory volume per second FEV1 (FEV1 = 4.50) represents 97% of the normal level. Within the ASU group, the value of the forced vital capacity (FVC = 5.19) represents 95% of the normal level, and the Expiratory volume per second (FEV1 = 4.45) represents 95% of the normal level. As we can see, neither of the groups reaches the normal potential. However, the CS UVT group reaches a higher percentage than the other, although they play their matches in a lower league.

Conclusions: Considering that we could not compare the types of training that the two teams had during the preparation phase, we cannot say whether such trainings had a certain effect on the subjects. Further research should be carried out in order to determine if the type of training had a beneficial effect in the case of the CS UVT group.
New study on the neuromuscular dystrophy rehabilitation program
Authors: Miclaus Roxana , Roman Nadinne 
Published: June 2020

Abstract
Neuromuscular dystrophy is a progressive disease, interesting skeletal muscles by progressive weakness and loss of voluntary motor function.

Material and Methods: A prospective study was developed on 16 patients with progressive neuromuscular dystrophy, over a three months period. The initial and final assessment included muscle manual testing, range of motion and, for the functional outcomes, the Vigos Scale, Barthel Scale, Activity of Daily Living (ADL) Score, and Muscular Dystrophy Scale were used. The physiotherapy program was developed on four stages and a guiding protocol was used for the individualization of the physical therapy program. The statistical analysis was performed in Microsoft Excel, using a Paired samples T-test.

Results: Statistical significant results were obtained within all assessment tools. Muscle strength and ADL capacity improved, with the highest increases in patients with low levels of disability.

Conclusion: The main results suggest that individualized physiotherapy can slow the progressivity of the disorder and improve the quality of life, especially when started at an earlier stage of the disease.

Published: June 2020

Abstract
It was proved by Jang et al. that various chains of one-parameter distributions converge to Benford’s law. We study chains of truncated distributions and propose another approach, using a recent convergence result of the Lerch transcendent function, to proving that they converge to Benford’s law for initial Beta distributions with parameters α and 1.
On the Maximum Order Complexity of the Thue-Morse and Rudin-Shapiro Sequence
Authors: Sun Zhimin , Winterhof Arne 
Published: June 2020

Abstract
Expansion complexity and maximum order complexity are both finer measures of pseudorandomness than the linear complexity which is the most prominent quality measure for cryptographic sequences. The expected value of the Nth maximum order complexity is of order of magnitude log N whereas it is easy to find families of sequences with Nth expansion complexity exponential in log N. This might lead to the conjecture that the maximum order complexity is a finer measure than the expansion complexity. However, in this paper we provide two examples, the Thue-Morse sequence and the Rudin-Shapiro sequence with very small expansion complexity but very large maximum order complexity. More precisely, we prove explicit formulas for their N th maximum order complexity which are both of the largest possible order of magnitude N. We present the result on the Rudin-Shapiro sequence in a more general form as a formula for the maximum order complexity of certain pattern sequences.
Quasi-Random Graphs, Pseudo-Random Graphs and Pseudorandom Binary Sequences, I. (Quasi-Random Graphs)
Authors: Borbély József , Sárközy András 
Published: June 2020

Abstract
In the last decades many results have been proved on pseudo-randomness of binary sequences. In this series our goal is to show that using many of these results one can also construct large families of quasi-random, pseudo-random and strongly pseudo-random graphs. Indeed, it will be proved that if the first row of the adjacency matrix of a circulant graph forms a binary sequence which possesses certain pseudorandom properties (and there are many large families of binary sequences known with these properties), then the graph is quasi-random, pseudo-random or strongly pseudo-random, respectively. In particular, here in Part I we will construct large families of quasi-random graphs along these lines. (In Parts II and III we will present and study constructions for pseudo-random and strongly pseudo-random graphs, respectively.)
