Femoral and Dega osteotomies in the treatment of habitual hip dislocation in down syndrome patients - is it efficient or not?
Authors: Aly Ahmad S. , Al-kersh Mohamed A. 
Published: May 2018

Purpose The purpose of this case series study is to report on the intermediate-term outcomes following a femoral varus derotational osteotomy (FVDO) performed in conjunction with a Dega osteotomy (DO) in management of hip ­instability in Down syndrome (DS) patients. Methods Ten hips in seven children with DS suffering from hip dislocation were included. All patients included in this study had hip dislocation in the habitual phase and painless mobile hip to full abduction. All patients were firstly subjected to FVDO. An additional DO was added if intraoperative assessment demonstrated posterior instability. The mean age at time of surgery was 5.6 years (3 to 7). There were three male and four female patients. All patients were followed up after two years with a mean follow-up of 3.27 years (2 to 5). All operations were performed by the first author. Results There was improvement of neck shaft angles (130° to 175°, median = 160° preoperatively, to 120° to 140°, median =130° postoperatively). The Shenton line was restored in all our cases. There was also improved percentage of the femoral head uncovered by the lateral wall of the acetabulum (25° to 100° with median = 45° preoperatively, to 0° to 15° with median = 5° postoperatively) and improved posterior acetabular coverage, which was assessed by CT. Conclusion FVDO combined with DO without ­capsulorrhaphy is efficient in the management of hip instability in DS, as it corrects hip biomechanics and increases posterior acetabular coverage.

Published: May 2018

Abstract
The rapid growth of the Chinese economy since the late 1970s has dramatically changed the dynamics of the marketplace. China’s consumer society has been transformed to a more liberal market system in which a variety of diverse market imageries have been created and circulated to consumers. This article examines how global fashion brands construct different ‘modern girl’ archetypes for consumers in the emerging Chinese market. Through conducting a semiotic analysis of printed advertisements published in four major fashion magazines during a four-year period from the beginning of 2009 to the end of 2012, we identified six ‘modern girl’ archetypes constructed by global fashion brands. Our findings reveal a dialogical relationship between brand-created imageries and prevailing cultural attitudes. We argue that fashion brands strategically create alternative modern girl archetypes as a way to depict a new era marked by the liberation of Chinese women under the influence of global consumer culture.

Published: May 2018

Abstract
The work presents the results of the investigations of the effect of inhibitors coated on the internal walls of a ceramic mould on the quality of the obtained casts made of the AM60 alloy containing additions of chromium and vanadium. In order to reduce the reactivity of magnesium alloy cast by the technology of investment casting with the material of the mould and the ambient atmosphere, solid inhibitors were applied in the form of a mixture of KBF4 and H3BO3 after the stage of mould baking and before the mould’s being filled with the liquid alloy. For the purpose of examining the effect of the inhibitors on the surface quality of the obtained casts, profilometric tests were performed and the basic parameters describing the surface roughness, Ra, Rz and Rm, were determined.

Polaroid Operators with Svep and Perturbations of Property (Gaw)
Authors: Rashid M.H.M. 
Published: May 2018

AbstractIn this paper we establish for a bounded linear operator defined on a Banach space several sufficient and necessary conditions for which property (gaw) holds. In this work, we consider commutative perturbations by algebraic operator and quasinilpotent operator for T ∈ B(X ) such that T * satisfies property (gaw). We prove that if A is an algebraic and T ∈ PS(X ) is such that AT = TA, then ƒ(T * + A*) satisfies property (gaw) for every ƒ ∈ Hc(σ(T + A)). Moreover, we show that if Q is a quasi-nilpotent operator and T ∈ PS(X ) is such that TQ = QT, then ƒ(T * + Q*) satisfies the property (gaw) for every ƒ ∈ Hc(σ(T +Q)). At the end of this paper, we apply the obtained results to a number of subclasses of PS(X ).

Published: May 2018

Abstract
The character of missions and conditions in which they are carried out by military un-manned aerial vehicles are usually special and difficult. This causes a necessity to provide support for their missions, especially with regard to checking their condition on the controlled or autonomic flight path, especially during landing and take-off operations.
This paper offers an account of an experiment and an attempt of assessing usefulness of thermal imaging cameras for controlling flights of aerial vehicles, mainly in areas of air-dromes and approach paths.

Authors: Wołejsza Piotr , Koszelew Jolanta 
Published: May 2018

AbstractThe known navigational systems in use and methods of navigational decision support perform information functions and as such are helpful in the process of safe conduct of a vessel. However, none of these known systems provides a navigator with ready solutions of collision situations taking account of all the vessels in the proximity of own ship, where the Collision Regulations apply. This paper presents verification results of NAVDEC — new Navigational Decision Supporting System created by research team from Szczecin Maritime University both for ocean going ships and pleasure crafts. Verification was carried out in real condition on board Motor Ferry ‘Wawel’ (m/f ‘Wawel’), which belongs to shipowner Polferries (PŻB). During the journey to/from Nynashamn system was tested from customer perspective. Few suggestions for improvements were issued, which were discussed in this article.
Exergy analysis of the Szewalski cycle with a waste heat recovery system
Authors: Kowalczyk Tomasz , Ziółkowski Paweł , Badur Janusz 
Published: May 2018

Abstract
The conversion of a waste heat energy to electricity is now becoming one of the key points to improve the energy efficiency in a process engineering. However, large losses of a low-temperature thermal energy are also present in power engineering. One of such sources of waste heat in power plants are exhaust gases at the outlet of boilers. Through usage of a waste heat regeneration system it is possible to attain a heat rate of approximately 200 MWth, under about 90 °C, for a supercritical power block of 900 MWel fuelled by a lignite. In the article, we propose to use the waste heat to improve thermal efficiency of the Szewalski binary vapour cycle. The Szewalski binary vapour cycle provides steam as the working fluid in a high temperature part of the cycle, while another fluid – organic working fluid – as the working substance substituting conventional steam over the temperature range represented by the low pressure steam expansion. In order to define in detail the efficiency of energy conversion at various stages of the proposed cycle the exergy analysis was performed. The steam cycle for reference conditions, the Szewalski binary vapour cycle as well as the Szewalski hierarchic vapour cycle cooperating with a system of waste heat recovery have been comprised.

Abstract
In this paper, we give some equivalence relations and results over the commutative quaternions and their matrices. In this sense, consimilarity, semisimilarity, and consemisimilarity over the commutative quaternion algebra and commutative quaternion matrix algebra are established. Equalities of these equivalence relations are explicitly determined. Also Syvester-s-Conjugate commutative quaternion matrix equations are studied by means of real representation of the commutative quaternion matrices and consimilarity of the two commutative quaternion matrices.

Authors: Ozen Kahraman Esen , Tosun Murat , Akyiğit Mahmut 
Published: May 2018

Abstract
The resolution of the acceleration vector of rigid body moving along a space curve is well known thanks to Siacci [1]. In this resolution, the acceleration vector is stated as the sum of two special oblique components in the osculating plane of the point of the curve. In this paper, we have studied the Siacci’s theorem for the curves on regular surfaces in 3-dimensional Euclidean space. Also, an example is given for a helix lying on a cylinder.

Published: May 2018

Abstract
The mixed problem for quasilinear hyperbolic system with coefficients functionally dependent on the solution is studied. We assume that the coefficients are continuous nonlinear operators in the Banach space C1(ℝ) satisfying some additional assumptions. Under these assumptions we prove the uniqueness and existence of local in time C1 solution, provided that the initial data are also of class C1.

Authors: Siraj Khalid , Deso Dema , Jado Demelash , Selale Girma 
Published: May 2018

Abstract
Adsorption of 8-hydroxyquinoline (8HQ) on powdered orange peel (POP), a locally available adsorbent, has been studied. Experiment was performed on different 8HQ concentration, particle size, and adsorbent dosage. The Langmuir and Freundlich adsorption isotherm model has been tested. The obtained results best fitted the Langmuir model, suggesting monolayer adsorption of 8HQ on POP. The kinetic studies for the adsorption process were also carried out using pseudo-first- and pseudo-second-order models, and the data obtained is best fitted to the pseudo-second-order kinetic model. Thermodynamic parameters were calculated for the adsorption process and the result showed that the values of ΔGads, ΔHads, and ΔSads are −1171.4J/mol, −140J/mol and −40.5 J/K at 303 K. Thus, it can be summarized that the adsorption of 8HQ is spontaneous, chemisorbed, monolayer, and exothermic
Calvary of the Germans in Hungary at the end of WWII
Authors: Matkovits-Kretz Eleonóra 
Published: May 2018

Abstract
The German community in Hungary suffered many blows at the end of World War II and after it, on the basis of collective guilt. Immediately after the Red Army had marched in. gathering and deportation started into the camps of the Soviet Union, primarily into forced-labour camps in Donetsk, the Caucasus, and the Ural mountains. One third of them never returned. Those left behind had to face forced resettlement, the confiscation of their properties, and other ordeals. Their history was a taboo subject until the change of the political system in 1989. Not even until our days, by the 70th anniversary of the events, has their story reached a worthy place in national and international remembrance. International collaboration, the establishment of a research institute is needed to set to rights in history the story of the ordeal of the German community after World War II. for the present and future generations

Published: May 2018

Abstract
The Institute of Military History of the Hungarian Ministry of Defence decided in 2000 to try to find the marked or unmarked graves of Hungarian soldiers killed in World War II. Joining this initiative, Jozsef Patakv founded the Committee for the Preservation of Military Traditions from Turda (THHB). Among other things, the aim of establishing the Committee was to discover the identity of the Hungarian soldiers that died in action in the fall of 1944 in Torda (in Romanian: Turda: in the followings, we will use the traditionally Hungarian name of the town: Torda) and its surroundings, find the location where they were buried, and erect a worthy monument to their memory. A Hungarian Soldier Graveyard was created within the Central Hungarian Cemetery of Torda, which has since become a place of pilgrimage. In addition, more then fifty sites of Hungarian soldiers’ graves were discovered and in most of the cases properly marked since that time. In 2012, Jozsef Patakv was awarded the Hungarian Gold Cross by the Ministry of Defence for his untiring work to discover the places of burial and identify Hungarian soldiers that died in WWII, and for worthily keeping their memories alive.

Authors: Szkiva Zs. , Bálint Á. M. , Füle M. , Nánai L. 
Published: May 2018

Abstract
Pulsed laser irradiated vanadium surface morphology under different ambient has been prepared and characterized using fractal dimension analysis method on scanning electron microscopy (SEM) images. In presence of different ambient, self-periodic and self-similar surface patterns (e.g. dots, islands, and pins) were grown and appeared in different shapes. The fractal dimension (FD) of this developed vanadium nanostructure was calculated by fractal box count method (FBM). The calculated fractal dimension (FD, Df) shows dependence on the different type on ambient and the number of laser shots.

relationship between student athletes’ behaviour in the classroom and teachers’ burnout level
Authors: Karakaya Yunus Emre , Brusseau Timothy A , Karademir Tamer 
Published: May 2018

Summary
Study aim: To examine the relationship between the behaviour of student athletes in the classroom in sport schools in Turkey and their teachers’ burnout level.

Material and methods: The sample of the study consisted of 226 teachers from sport high schools in Turkey. A questionnaire developed by Özdemir (2009) was used to ascertain students’ unwanted behaviour and the Maslach burnout inventory developed by Maslach and Jackson (1981) was used to assess the views of the research group. The data obtained were analysed through the SPSS 18.0 software.

Results: The research group complained of student behaviour including ‘speaking without permission’ during the course, ‘not having the necessary equipment for the course’, ‘not performing a given task’ and ‘not listening to the teacher’. A positive linear and moderate level relationship was found between the emotional burnout and depersonalization sub-dimensions. Suggesting that, as emotional burnout level increases so does the level of indifference. A positive and linear but low-level relationship was found between the emotional burnout and personal failure sub-dimensions. Suggesting that, as emotional burnout level increases so does personal failure. In addition, a positive and linear but low-level relationship was observed between the depersonalization and personal failure sub-dimensions. In other words, as the level of indifference increases so does personal failure. A significant difference was seen in the period of service variable of the depersonalization sub-dimension in the research group. Significant differences were observed in accordance with personal failure, period of service and fields of study.

Conclusions: Teachers should analyse their students in terms of academic and personal development in order to reduce negative behaviours in the classroom. Teachers should be able to help students in whatever field they need. Teachers in sports schools should receive support in adapting to the institutional culture of the schools.

Notes On Alien Plant Species Amorpha Fruticosa New To Lithuania
Authors: Gudžinskas Zigmantas , Žalneravičius Egidijus 
Published: May 2018

Abstract
Woody plant species in recent decades have increasingly often been recorded escaped from cultivation and naturalized. In 2013, a new alien woody species Amorpha fruticosa L. (Fabaceae) was first found in Lithuania. In several Central European countries, A. fruticosa is recognized as invasive species that pose serious threat to natural habitats and ecosystems. To date, A. fruticosa has been registered in three localities in Lithuania: two populations in Ukmergė district and one population in Prienai district. Considering the present state of revealed A. fruticosa populations, it is concluded that this species in Lithuania is already naturalized and potentially invasive. Estimated total area occupied by A. fruticosa in three known localities is about 0.2 ha. In certain areas this species can become abundant and invade significant areas of meadow, forest-edge and other open habitats. Therefore, its immediate control and subsequent eradication can reduce risk of future invasion. Cultivation of A. fruticosa should be forbidden outside the ornamental plantations.

Published: May 2018

Abstract
Currently, patients with isolated peritoneal surface malignancies are treated with a combination of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). This combination should now be considered the standard of care for appendiceal cancers (including pseudomyxoma), colorectal cancer and peritoneal mesothelioma, while patients with peritoneal metastases from ovarian or gastric cancer may be treated within clinical trials. At present, 8 clinical centres in Poland perform CRS and HIPEC. The unanswered problems of combined intraperitoneal therapy were an impulse for the organization of the 4th International Conference “Advances in Surgical Oncology” that was held on November 23-24, 2017, in Lublin (Poland), and the Polish chapter of the Peritoneal Surface Oncology Group International (PSOGI) was established as a result of this meeting. This special issue of the Current Issues in Pharmacy and Medical Sciences is dedicated to the current therapeutic difficulties discussed during the two days of the conference – experiences that were exchanged to set in motion further directions for the improvement of intraperitoneal treatment.
