A computational homogenization analysis of materials using the stabilized mesh-free method based on the radial basis functions
Authors: Phuc Ho Le Huy , Canh Le Van , Hung Phan Duc 
Published: January 2020

This study presents a novel application of mesh-free method using the smoothed-radial basis functions for the computational homogenization analysis of materials. The displacement field corresponding to the scattered nodes within the representative volume element (RVE) is split into two parts including mean term and fluctuation term, and then the fluctuation one is approximated using the integrated radial basis function (iRBF) method. Due to the use of the stabilized conforming nodal integration (SCNI) technique, the strain rate is smoothed at discreted nodes; therefore, all constrains in resulting problems are enforced at nodes directly. Taking advantage of the shape function satisfies Kronecker-delta property, the periodic boundary conditions well-known as the most appropriate procedure for RVE are similarly imposed as in the finite element method. Several numerical examples are investigated to observe the computational aspect of iRBF procedure. The good agreement of the results in comparison with those reported in other studies demonstrates the accuracy and reliability of proposed approach.

homogenization analysis; mesh-free method; radial point interpolation method; SCNI scheme.
A three-dimensional model for rain-wind induced vibration of stay cables in cable-stayed bridges
Authors: Hung Truong Viet , Viet Vu Quang , Anh Vu Quoc 
Published: January 2020

In this paper, the effects of wind velocity according to height above the ground on the rain-wind induced vibration (RWIV) of stay cables are investigated. RWIV of the cable is modeled using the linear theory of cable vibration and the central difference algorithm. The wind speed profile according to height above the ground, which affects both aerodynamic forces acting on the cable and the oscillation of the rivulet on the cable surface, is taken into account in the theoretical formulation. The fourth-order method Runge-Kutta is used for solving the system of differential equation of the cable oscillation. The proposed 3D model of the stay cable is then used to assess the effects of wind velocity distribution on cable RWIV. The results obtained in this study showed that in most current cable-stayed bridges, in which the height of pylons is lower than 200 m, the change of wind velocity according to the height above the ground should be included in RWIV analyses.

An experimental study on the structural performance of reinforced concrete low-rise building columns subjected to axial loading
Authors: Dat Pham Xuan , Vu Nguyen Anh 
Published: January 2020

It has been commonly recognized by the international research and practice community that the presence of both outer and inner stirrups may significantly enhance the axial load capacity of reinforced concrete (RC) columns. However, there is limited testing evidence to support this conclusion that has been published nationally. This paper reports an experimental programme to study the effectiveness of stirrup detailing on the structural performance of columns having small sectional dimensions that are common in low-rise building structures. Nine column specimens with the same geometrical dimensions of 220 mm x 220 mm x 880 mm in three batches were detailed with different stirrup categories, have been gradually axially loaded to failure. The test data have revealed that although the presence of stirrups can generally enhance the axial load capacity of the column specimens, the enhancing levels are much dependent to the shapes of the stirrups. Selected interesting aspects of the test results have also been discussed, which set a concrete base for recommendations for design and detailing of such vertical structural elements.

Optimal parameters of tuned mass dampers for machine shaft using the maximum equivalent viscous resistance method
Authors: Chinh Nguyen Duy 
Published: January 2020

The paper analyzes and determines the optimal parameters of tuned mass damper to reduce torsional vibration for the machine shaft. The research steps are as follows. First, the optimal parameters of tuned mass damper for the shafts are given by using the maximization of equivalent viscous resistance method. Second, a numerical simulation is performed for configuration of machine shaft to validate the effectiveness of the obtained analytical results. The simulation results indicate that the proposed method significantly increases the effectiveness of torsional vibration reduction. Optimal parameters include the ratio between natural frequency of tuned mass damper and the machine shaft, the ratio of the viscous coefficient of tuned mass damper. The optimal parameters found by numerical method only apply to a machine shaft with specific data. However, the optimal parameters in this paper are found as analytic and explicit to help scientists easily apply to every machine shafts when the input parameters of the machine shaft change.
Keywords:
tuned mass damper; torsional vibration; optimal parameters; random excitation; equivalent viscous resistance.

AYVACIK’TA (ÇANAKKALE) SURİYELİLERİN GÖÇ VE YERLEŞİM SÜREÇLERİ ÜZERİNE BİR ARAŞTIRMA
Authors: TAŞKIN Kerim , ÖZÖZEN KAHRAMAN Selver 
Published: January 2020

2011’de Suriye’de başlayan iç savaş sonrasında Suriyeliler Türkiye’ye
göç etmiş ve “Geçici Koruma” kapsamında kamplara ve çeşitli yerleşim
birimlerine yerleşmişlerdir. Türkiye’yi transit ülke olarak
kullanan ve AB’ye geçmeyi amaçlayan Suriyeliler özellikle Türkiye’nin batı
kıyısındaki kara ve deniz sınırlarını düzensiz göç güzergâhları olarak
kullanmışlardır. Bu güzergâh üzerindeki Ayvacık (Çanakkale), Midilli adasına (4
mil) en yakın yerleşim yeridir. Bu durum Suriyelilerin Ayvacık’ı
düzensiz göç güzergâhı olarak seçmelerinde etkili olmuştur. 2017’nin ikinci
yarısından itibaren Yunanistan sınırına yakın kıyılarda alınan tedbirler
nedeniyle düzensiz göçler durma noktasına gelmiş, Suriyelilerin Ayvacık’a göçleri azalmıştır. Ayvacık’ı düzensiz göç
güzergâhı olarak gören Suriyelilerin, zamanla düzensiz göç girişimleri
zorlaşmıştır. Bu nedenle Suriyeliler Ayvacık’ı geçici bir göç güzergâhından
ziyade ikamet edilecek bir yerleşim yeri olarak görmeye başlamışlardır. Bu
makalede Ayvacık’ta ikamet eden Suriyelilerin demografik özellikleri, ekonomik
faaliyetleri, gelecek beklentileri ve yerli halkla ilişkileri araştırılmıştır.
Yerli halktan 54, Suriyelilerden 61 kişiyle yüz yüze mülakat yöntemiyle veriler
toplanarak analiz edilmiş ve yorumlanmıştır. Suriyelilerin Ayvacık’a göç
tercihlerinde iş olanakları ve tanıdıklarının olması etkili olmuştur.
Suriyelilerin Ayvacık’tan memnun oldukları görülürken, yerli halkın
Suriyelilerle ilgili tutumları mahallelere göre farklılıklar
göstermektedir.

Published: January 2020

Objectives: Combined functional MRI (fMRI) and diffusion tensor tractography (DTT) imaging provides a powerful vehicle for the investigation of motor recovery mechanisms. Using this combined method, we investigated the motor recovery mechanism in patients with pontine infarct. Design: We evaluated six healthy control subjects and two patients with pontine infarct at 6 months from onset. fMRI was performed at 1.5 T with timed hand grasp-release movements. For DTT, we used each of the 32 noncollinear diffusion-sensitizing gradients. Three-dimensional reconstructions of the fiber tracts were obtained with FA <0.3, angle >45° as termination criteria. Results: fMRI data revealed activation only in the contralateral primary sensorimotor cortex during movement of either hand. DTI findings from controls and the unaffected hemisphere of the patients showed that the corticospinal tract descended through the known corticospinal tract pathway. However, the tracts of the affected hemisphere in the patients were observed to pass along peri-infarct areas (patient 1: lateral, patient 2: posterior) in the pons. Conclusions: It seems that the peri-infarct areas compensate for corticospinal tract damage at the pons; this may be one mechanism of motor recovery for patients with pontine infarct.

Published: January 2020

Objectives: To evaluate the functional status, leisure activity and satisfaction in adult stroke survivors participating in a community rehabilitation program, and to compare these outcomes with stroke survivors not attending any program. Method: Subjects included in the study were survivors of a first stroke that received inpatient rehabilitation and were living at home at least one year post onset. Twenty seven were participants in a community rehabilitation program and 56 were non-participants. The outcome measures were the Stroke impact Scale (SIS), Functional Independence Measure (FIM), Instrumental Activities of Daily Living Questionnaire (IADLq), Activity Card Sort (ACS), and the Life-Satisfaction questionnaire (Li-Sat-9). Results: The results revealed severe stroke impact and low functioning in activities of daily living in the participant group, yet the level of participation in leisure activities improved significantly after attending the program ( t = −8.1, p = 0.000). The comparison with the non participant group revealed that participants were even more disabled in basic activities of daily living (as measured by the FIM) than non-participants ( t = −3.1, p = 0.004). However, the satisfaction rates of the participants were significantly higher than non participants from "life as a whole" and from their leisure situation (p < 0.05). Conclusions: Stroke survivors participating in a community based rehabilitation program did not show an advantage in terms of disability levels over non-participants. However, their activity level increased due to the program and their satisfaction scores were higher than non-participants.
Protein synthesizing function and the functional state of liver of rats for the continuous cadmium and lead load
Authors: Slobodian S. O. , Gutyj B. V. 
Published: January 2020

The aim of the study was to investigate the effect of Cadmium and Lead on the protein synthesis and function of the rat liver. The experiments were conducted in male rats of the Wistar line, weighing 200–220 g, of which 4 groups of animals were formed: 1) a control group – injected drinking water through a metal probe in a volume equivalent to the volume of an aqueous solution of Cd2+ salts and Pb2+; 2) experimental group 1 – animals were administered a 0.029% aqueous solution of cadmium chloride at a dose of 4.0 mg/kg; 3) experimental group 2 – animals were administered 16.6% aqueous lead acetate solution at a dose of 200 mg/kg; 4) experimental group 3 – animals were administered 16.6% aqueous lead acetate solution at a dose of 100 mg/kg and 0.029% aqueous cadmium chloride solution at a dose of 2.0 mg/kg. Throughout the experiment, rats were kept in a balanced diet containing all the necessary components, and animals were given drinking water, without restriction, from 0.2 liter glass bowls. The functional state of the liver of rats under the conditions of use of salts of heavy metals was investigated by the activity of aminotransferases. In long-term lead-cadmium loading in rats of the experimental groups, the functional state of the liver is characterized, which is characterized by an increase in the permeability of biological membranes of the cell membranes, which causes hyperfermentemia in blood serum, in particular aminotransferase (AST, ALT). The high activity of ALT and AST in the serum of rats under the influence of Cadmium and Lead indicates the destructive processes in the liver that cause an increase in the output of aminotransaminases from cell organelles in the blood of experimental animals. Thus, the results obtained indicate an increase in the destructive processes in the body of rats under lead-cadmium loading. Important diagnostic value for intoxication of different etiology is the determination of protein synthesis of liver function. An important indicator of liver protein synthesis is the level of total protein and its fractions in the serum. This indicator reflects the changes that occur in the body in different pathological conditions. When loaded with heavy metals in the body of rats inhibits the protein synthesis function of the liver, which is manifested by a decrease in total blood protein and albumin levels.
Influence of medication “Membranostabil” on expression of immunoreceptor proteins in small intestine of ruminants during the period of formation of colostral immunity
Authors: Holopura S. I. , Tsvilikhovsky M. I. , Popadiuk B. V. 
Published: January 2020

The influence of medication “Membranostabil” on the indexes of content of proteins with MM of 33, 40, and 47 kDa in the plasmolemma of enterocytes of jejunum of new-born calves during the period from birth till the age of 24-hours was investigated. The research was conducted on calves (males) of Ukrainian black-and-white breed during the spring. Throughout the trial period, the calves of the control and experimental groups were kept on a standard diet for newborn calves, colostrum. In addition, calves of the experimental group got the medication “Membranostabil” based on the soybean lecithin. Proteins of plasmolemma of enterocytes of the jejunum of calves were isolated from the membrane fraction of lysates and examined by electrophoresis. Electrophoretic separation of proteins of plasmolemma of the jejunum enterocytes of newborn calves revealed proteins with MM of 37, 40 and 43 kDa on electrophoregram. The data of expression of immunoreceptor proteins with MM of 37, 40, 43 kDa and the dynamics of their changes depending on the time after birth in calves of the control and experimental groups were analyzed. The decrease in the total content of expression of proteins with MM of 37, 40, and 43 kDa in the membrane fraction of lysates of enterocytes of the jejunum of calves at the age of 6 hours compared to the newborn ones was demonstrated. The levels of expression of each immunoreceptor protein are considered with their comparative analysis between the individual fractions in the cytolemma of the enterocytes of the jejunum of newborn calves, which according to their molecular weights correspond to MM isoforms of FcγRIII/CD32. The data obtained showed a significantly higher expression of level of proteins with molecular mass of 37 kDa on the apical membrane of enterocytes, compared with proteins with MM of 40 and 43 kDa, both at birth of calves and at the age of 6 and 24 hours. Based on the data obtained, proteins with MM of 37, 40, and 43 kDa of plasmolemma of the jejunum enterocytes undergo significant changes in the process of postnatal ontogeny in cattle. These changes indicate the synthesis of these proteins in the enterocytes themselves in the process of formation of colostral immunity in newborn calves under the influence of the medication “Membranostabil” used by this research group, compared with calves of the control group. It is shown that the application of medication “Membranostabil” for the new-born calves activates the transport of immunoglobulins of colostrum in the intestine of these animals, assists the increasing of level of colostral immunity, and prevents the occurrence of digestive disorders. Findings of this research correlate with the results of clinical observation in newborn calves.
„Zvířecí” výrazy pro lidský svět. Opozice člověk – zvíře v češtině

Polskie tłumaczenie skróconej wersji artykułu w tekście.
Svět zvířat je vždy nahlížen z lidské perspektivy, oba světy jsou proto vzájemně propojené a neoddělitelné. Příspěvek si klade za cíl sledovat různé projevy antropocentrismu v češtině. Zaměřuje se zejména na výrazy, které lidský a zvířecí prostor propojují a označují skutečnosti, jež mají své ekvivalenty na obou stranách. V češtině často existují dvě série jednotek označujících stejnou skutečnost – pro člověka a pro zvíře. Odlišná slova použijeme např. pro označení částí těla člověka a částí těla zvířete (hlava, ústa X rypák, tlama, zobák), pro různé činnosti (jíst X žrát), zvuky (mluvit X skřehotat, mečet, kdákat) atd. Použijeme-li navíc primárně „zvířecí” výrazy ve vztahu k lidem, přinášejí s sebou výrazně negativní hodnocení. Text je založen především na analýze českého slovníkového materiálu, uváděny jsou také příklady z folklorních textů.

Public policymaking and its analysis at National and European Levels
Authors: Majone Giandomenico 
Published: January 2020

The author describes the specific features of public policy process at the European Unionlevel and its differences related to policy-making at national level. He underlines, amongother things that the policy agenda in the European Union is being shaped differently.At the national level the agenda is under greater influence of politicians who are closelyinterconnected with voters. At the European Union level the technocratic (not directlyelected) European Commission has a monopoly of legislative initiative. Furthermore, atthe European level feasibility studies – as an element of the pre-decision stage in publicpolicy-making – tend to be ignored. In nation-states we can see such analyses as a resultof competition taking place between those who rule and their political opposition. Atthe European Union level it is not the case. The author points out that these mechanisms would have been beneficial for the EU member states. They would have haltedthe implementation of decisions which ran the excessive risk. He has also in mind thedecision related to the introduction of the monetary union. In his opinion, this decisionwas made without a proper feasibility analysis (costs and profits). Basically, the decisionon a common currency was made on political rather than substantive grounds. A largenumber of experts were against the idea as they perceived serious risks involved in it.The supporters of greater European integration ignored the fact that the monetary uniondeprived nation-states of many factors that affected the economic development in a positive way. The point is that they were under influence of “total optimism” expecting only good results of the monetary union. The mechanisms of crisis management, including exitscenario from the monetary union, or methods of supporting those members who needfinancial aid, have not been even created. Furthermore, the evaluation of the monetaryunion was not properly carried out as it was based on the assessment of the process (forexample, smooth introduction of euro notes and coins or phasing out of the nationalcurrencies in 2002) and not of its results
Labirynty konceptualizowania Unii Europejskiej i suwerenności jej państw członkowskich
Authors: Czaputowicz Jacek 
Published: January 2020

Autor przedstawia i podsumowuje główne teorie opisujące specyfikę Unii Europejskiej jako organizmu wewnętrznie złożonego, który ma cechy zarówno organizacji międzynarodowej, konfederacji, jak i federacji. Wielu badaczy porównuje proces tworzenia UE do procesu powstawania państwa, ale niektórzy porównują Unię do Stanów Zjednoczonych. Jeszcze inni badacze twierdzą, że struktura UE z jej wielopoziomowym systemem rządów przypomina neośredniowieczne imperium. Występują w niej zachodzące na siebie systemy władzy i obszary lojalności.
Autor wskazuje także, że strukturalnie funkcjonowanie UE można zobrazować za pomocą modelu wielopoziomowego zarządzania (multilevel governance). W tym modelu Unię Europejską można uznać za system polityczny sui generis; nie jest więc ona analogiczna do państwa narodowego, lecz traktowana jak system zarządzania bez formalnego rządu.Pojęcie to odnosi się do wzrostu współzależności w sferze ponadnarodowej. W drugiej części tekstu autor analizuje problematykę suwerenności państw i samej Unii. Dokonuje przeglądu stanowisk, które w różny sposób oceniają poziom wpływu, jaki proces europeizacji wywiera na politykę wewnętrzną państw.
Polityka Unii Europejskiej przeciwdziałająca szkodliwej międzynarodowej optymalizacji opodatkowania
Authors: Gajewski Dominik Jan 
Published: January 2020

Działalność holdingów międzynarodowych stała się kluczowa dla gospodarki europejskiej. Szczególną uwagę należy zwrócić na aspekty podatkowe, które są związane z transgraniczną działalnością holdingów. Coraz częściej stosują one w swojej strategii agresywną optymalizację opodatkowania. Polityka podatkowa poszczególnych państw członkowskich okazała się mało skuteczna. Jednocześnie brak wspólnej i zharmonizowanej polityki podatkowej przeciwdziałającej optymalizacji opodatkowania stał się poważnym problemem dla Unii Europejskiej. Dlatego ideą Komisji Europejskiej jest – z jednej strony – wypracowanie koncepcji podatkowej, która będzie w stanie skutecznie przeciwdziałać międzynarodowej optymalizacji opodatkowania stosowanej przez holdingi, z drugiej zaś – będzie integralna z wewnętrznymi systemami podatkowymi państw członkowskich.
