The possibility of obtaining wood and plant plastics without a binder (WP-WB) in the presence of a catalyst of man-ganese-containing sodium vanadomolybdophosphate has been investigated. The use of this catalyst makes it possible to reduce the temperature of hot pressing in closed molds from 1,800°C to 1,600°C. The fractional composition of the initial press raw material influences physical and mechanical properties of WP-WB. Higher values of the plastic properties are obtained by using a 0.7 mm fraction, which is associated with an increased specific surface area of the particles compared to 1.3 mm particles. The results has showed that the samples obtained by using the catalyst have increase in strength properties (flexural strength, flexural modulus, hardness) at lower pressing temperature, but reduction of water resistance performance has been observed . This is explained by the increase in the content of functional groups when using a catalyst. The process of obtaining plastic can be broken down into two successive stages: the first is hydrothermal destruction of lignin-carbohydrate complex (initial moisture of the press raw material is 12%, the temperature of hot pressing in closed molds is 160 ... .180 ° C) and partial chemical activation of lignin as a result of hydrogen peroxide and catalyst application; the second stage - formation of plastic with the formation of a network structure due to the formed functional groups. It is established that the values of physical and mechanical properties of WP-WB are higher than those of plastic obtained on the basis of plant raw materials (PP-WB). This can be explained by the fact that lignin of coniferous species has the guaiacylpropane structure, while plant raw material has a hydroxyphenylpropane structure

Deconstructing Cultural Icons – Sherman Alexie and Junot Díaz
Authors: Gondor-Wiercioch Agnieszka
Published: March 2018

This paper addresses the problem of the representation of Native American and Latino/a identity in Sherman Alexie’s collection of short stories, The Lone Ranger and Tonto Fistfight in Heaven (1993), and Junot Díaz’s, This Is How You Lose Her (2012). Both authors try to the deconstruct popular ethnic stereotypes of the Indian Warrior and the Macho by creating characters such as Victor Joseph and or Yunior, who learn to reject the violence-based legacies of their respective cultures and try to substitute them with new hybrid identities, thus proving that it is possible to transform one’s ethnic heritage without getting completely acculturated. This paper also attempts to demonstrate that Alexie and Díaz play a very important role in the discussion of postethnic space by emphasizing the dangers of perceiving the Other through the prism of mass-fabricated images. They continue the long tradition established by authors such as Gerald Vizenor, Louis Owens, Arnold Krupat, Octavio Paz, Mario Vargas Llosa, and others. Additionally, Alexie and Díaz incorporate survival humor into their narratives, which makes their characters more credible and universal.

A globalização como fator de (i)mobilidade das pessoas sob o enfoque do relatório “forced displacement in 2015” da agência para refugiados da Organização das Nações Unidas
Authors: Puerta Neto Hélio Lentz , Santos Rafael Padilha dos
Published: March 2018

O deslocamento forçado de pessoas não é algo novo, o que muda, na verdade, é a direção dos acontecimentos. Se na primeira metade no século XX o deslocamento Norte-Sul foi realizado com políticas migratórias favoráveis aos refugiados, atualmente, no movimento inverso (Sul-Norte) não acontece. Apesar da Europa ocidental sofrer com o processo migratório, sobretudo a partir da Primavera Árabe (2010), os números globais divulgados no relatório “Global Trends – Forced Displacement in 2015” da Agência dos Refugiados da Organização das Nações Unidas demonstram que não há comparação com o que ocorre nos países “em desenvolvimento”. Ainda que fragilizados, estes países recebem um número absurdamente maior de refugiados. O fenômeno da globalização teve um preço e quem o está pagando são justamente aqueles que menos condições possuem. Denota-se, portanto, que há uma hierarquia estabelecida: o norte, global e livre, indicando a promoção social, progresso e sucesso; e o sul, local e preso, imóvel à própria desgraça. A emancipação de poucos para a submissão de muitos. A humanidade está (ou continua) em crise e a academia tem papel relevante no fortalecimento de bases teóricas para se alcançarem, na prática, soluções duradouras com abrangência legal, econômica, cultural e política, direcionadas principalmente aos países “em desenvolvimento”, para que estes possam enfrentar o problema migratório.

Keadilan Sosial dalam Perspektif Al-Qur’an Dan Pancasila
Authors: Fatihin Roro
Published: March 2018

Social justice has always been the most significant component in determining the orientation and objectives of social life. Issues frequently arise in relation to social discrepancies initiated by ensuing injustices, this further instigates crucial tension among groups, particularly in the field of economic welfare. As a unitary state, Indonesia has high aspirations of accomplishing life goals that rise up from the spirit ideology of Pancasila. As an ideology, Pancasila is not an objective, it functions as a means of achieving an objective. The objective of such mutual perspective of life is nothing but the creation of a developed, prosperous, and wealthy society in which it is embodied in the spirit of social justice. This study attempts to uncover substantial matters pertaining to the concept of social justice according to Al-Qur’an and Pancasila, wherein both are inseparable from the spirit of the Indonesian community in a broad sense. As a Muslim living in Indonesia, Al-Qur’an and Pancasila have become indivisible. They serve as a foundation and guidance in attaining a wealthy and prosperous life. In this context, I try to find the point of agreement on the concept of social justice between Al-Qur’an and Pancasila in order to find similarities or harmony between the two. My aim is to synergize the power of religion and the power of state ideology in order to easily accomplish the objectives and aspirations of civil society[Keadilan sosial selalu saja menjadi bagian paling penting dalam menentukan arah dan tujuan suatu kehidupan bermasyarakat.Seringkali masalah muncul berkenaan dengan adanya ketimpangan sosial yang bermula dari ketidakadilan yang menyertainya, hal ini memicu adanya ketegangan yang krusial antar kelompok, khsususnya dalam bidang kesejahteraan ekonomi.Sebagai negara kesatuan, Indonesia memiliki cita-cita tinggi untuk mencapai tujuan hidup yang bertitik tolak dari semangat dan Ideologi Pancasila. Sebagai ideologi, Pancasila bukanlah tujuan, tetapi ia berfungsi sebagai sarana untuk sampai pada suatu tujuan. Tujuan dari pandangan hidup bersama tersebut tak lain adalah terciptanya masyarakat yang maju, makmur, dan sejahtera yang kemudian hal ini tertuang dalam semangat keadialan sosial. Penelitian ini mencoba menggali hal penting tentang konsep keadilan sosial menurut Al-Qur’an dan Pancasila, kedua hal tersebut sama sekali tidak bisa dipisahkan dari semangat masyarakat Indonesia secara luas. Sebagai masyarakat Muslim yang tinggal di Indonesia, Al-Qur’an dan Pancasila sudah menjadi bagian yang tak terpisahkan.Ia menjadi dasar sekaligus pegangan untuk mencapai suatu kehidupan yang makmur dan sejahtera. Dalam konteks ini, peneliti mencoba menemukan titik temu antara konsep keadilan sosial dalam perspektif Al-Qur’an dan Pancasila guna mencari persamaan atau keselarasan diantaranya keduanya.Tujuanny adalah untuk mensinergikan antara kekuatan agama dengan kekuatan ideologi negara, agar tujuan dan cita-cita sebagai masyarakat yang madani dapat dicapai dengan mudah.]
Identification of early biomarkers in proteomic profiles of the phaeophyteSaccharina japonicaproximal to and beneath the front of bryozoan colonies
Authors: Getachew Paulos , Nam Bo-Hye , Hong Yong-Ki
Published: March 2018

The sessile bryozoanMembranipora membranaceafrequently colonizes the phaeophyteSaccharina japonica.Identifying early colonization markers using proteomics could assist in the early detection of epiphytic contamination. Different sections of thallus tissue proximal to the bryozoan (i.e. the 1-cm zone beyond the boundary of the colony) and tissue from the colony-front (i.e. the narrow zone under the newly formed front of the colony after removing the bryozoans) were separated. From the proteomic profiles ofS. japonica, we detected 151 protein spots (99 up-, 50 down-, and 2 similarly regulated) from proximal tissues and 151 spots (69 up-, 75 down-, and 7 same-regulated) from colony-front tissues. Hundred and ten spots were detected from distal healthy thallus tissue, used as a control. The protein SSP15 was specifically up-regulated in the proximal tissues by ca. 1395-fold, while it exhibited little expression at the colony-front and in distal healthy tissues. ATPases were markedly up-regulated in both the proximal and colony-front tissues by 3198- and 2475-fold, respectively. Rpl1P and SRSF proteins were specifically up-regulated only in colony-front tissues by 5724- and 273-fold, respectively. Therefore, these proteins may be used as specific biomarkers for the early detection of bryozoan colonization on each tissue type of the seaweed.
New Nordic Environments in Eyvind Johnson’s Factual and Fictional Prose, 1928–1932
Authors: Thomsen B. Thorup
Published: March 2018

The main aim of the article is to offer a closer examination of interfaces between Johnson’s factual and fictional modes of writing around 1930, with a particular emphasis on analysing accounts and appreciations of modern environments, infrastructures and mentalities in “peripheral” as well as “central” Swedish locations. To frame theoretically this examination, the article opens by considering some aspects of the current scholarly discourses on the hybrid genre of travel writing, to which the nonfictional texts in question broadly belong, and on the interrelationship between factual and fictional modes of representation. The article goes on to consider three of Johnson’s newspaper reportage pieces that may be located in the subgenre of domestic travel writing, popular in the interwar period, while they also, as “foreign” correspondence of sorts, contribute to confounding the very concept of home nation as well as challenging the distinction between “off-centre” and “centre” in the nation space. In its third phase, the article discusses two novels that illustrate, respectively, the “marginal” and the metropolitan variant of domestic modernism in Johnson’s fictional work, thus complementing the reportage pieces. The article concludes by situating the discussion of Johnson’s narratives in the context of new approaches to Scandinavian literary modernism.
Orte und Nicht-Orte im Werk Klaus Rifbjergs
Authors: Schlosser Jan T.
Published: March 2018

For the first time Klaus Rifbjerg’s diary Berlinerdage (1995) and other of his most important prose and lyric texts from different periods of his authorship are examined in the context of Marc Augé’s theory of places and non-places in this paper. The analysis of Rifbjerg’s texts focuses on the implicit presence of places and non-places. Reading Rifbjerg in context of Augé and Walter Benjamin’s Berliner Kindheit um neunzehnhundert (final version 1938) opens up for a new research position; it proves Rifbjerg’s considerable interest in German culture, and elucidates his opposition to ‘supermodernity’. Places and non-places are palimpsests in Rifbjerg’s texts about Berlin’s and Copenhagen’s urbanity. His texts focus on cultural continuity and historical foundation of modern life.
Efficient Redundancy Techniques in Cloud and Desktop Grid Systems using MAP/G/c-type Queues
Authors: Chakravarthy Srinivas R. , Rumyantsev Alexander
Published: March 2018

Cloud computing is continuing to prove its flexibility and versatility in helping industries and businesses as well as academia as a way of providing needed computing capacity. As an important alternative to cloud computing, desktop grids allow to utilize the idle computer resources of an enterprise/community by means of distributed computing system, providing a more secure and controllable environment with lower operational expenses. Further, both cloud computing and desktop grids are meant to optimize limited resources and at the same time to decrease the expected latency for users. The crucial parameter for optimization both in cloud computing and in desktop grids is the level of redundancy (replication) for service requests/workunits. In this paper we study the optimal replication policies by considering three variations of Fork-Join systems in the context of a multi-server queueing system with a versatile point process for the arrivals. For services we consider phase type distributions as well as shifted exponential and Weibull. We use both analytical and simulation approach in our analysis and report some interesting qualitative results.

Published: March 2018

A thermodynamic model for calculating the mass action concentrations{N_i}of structural units in Fe–Al binary melts based on the atom–molecule coexistence theory,i. e., AMCT–{N_i}model, has been developed and verified to be valid by comparing with reported activities{a_{{\rm{R, }}i}}of both Al and Fe relative to pure liquid as standard state in Fe–Al binary melts over a temperature range from 1823 to 1973 K (1550  to 1700 °C). Furthermore, Raoultian activity coefficients\gamma _i^0of both Al and Fe in the Fe-rich corner or Al-rich corner of Fe–Al binary melts as well as the standard molar Gibbs-free energy changes{\Delta _{{\rm{sol}}}}G_{{\rm{m, }}i{\rm{(l)}} \to {{{\rm{[}}i{\rm{]}}}_{{\rm{ [ \% }}i]{\rm{ = 1}}{\rm{. 0}}}}}^{\Theta {\rm{, \% }}}of dissolved Al or Fe for forming [% Al] or [% Fe] as 1.0 in Fe–Al binary melts have also been determined by the developed AMCT–{N_i}model and verified to be accurate.

The reported activities{a_{{\rm{R, }}i}}of both Al and Fe from the literature can be well reproduced by calculated mass action concentrations{N_i}of free Al and free Fe in Fe–Al binary melts. A small effect of changing temperature from 1823 to 1973 K (1550  to 1700 °C) on reaction abilities of both Al and Fe from the available literature is also confirmed by calculated mass action concentrations{N_i}of free Al and free Fe in Fe–Al binary melts. The obtained activity coefficients{\gamma _i}of both Al and Fe in Fe–Al binary melts can be described by a quadratic polynomial function and a cubic polynomial function, respectively. Furthermore, accurate expressions of Raoultian activity coefficients\gamma _i^0of both Al and Fe in Fe-rich corner or Al-rich corner of Fe–Al binary melts are also obtained as\ln \gamma _{{\rm{Al}}}^0 = - {\rm{9, 646}}{\rm{. 5}}/T{\rm{ + 2}}{\rm{. 196}}and\ln \gamma _{{\rm{Fe}}}^0 = - {\rm{6, 799}}{\rm{. 1}}/T - {\rm{0}}{\rm{. 01367}}, respectively. In addition, expressions of the first-order activity interaction coefficients\varepsilon _i^iore_i^iorh_i^iof both Al and Fe coupled with three activity coefficients\gamma _i^{}orf_{ \% {\rm{, }}i}^{}orf_{{\rm{H, }}i}^{}relative to three standard states are also obtained from the developed AMCT–{N_i}model for Fe–Al binary melts.
Shapes of an Air Taylor Bubble in Stagnant Liquids Influenced by Different Surface Tensions
Authors: Lertnuwat B.
Published: March 2018

The aim of this work is to propose an empirical model for predicting shapes of a Taylor bubble, which is a part of slug flows, under different values of the surface tension in stagnant liquids by employing numerical simulations. The k - Ɛ turbulence model was used in the framework of finite volume method for simulating flow fields in a unit of slug flow and also the pressure distribution on a Taylor bubble surface. Assuming that an air pressure distribution inside the Taylor bubble must be uniform, a grid search method was exploited to find an appropriate shape of a Taylor bubble for six values of surface tension. It was found that the shape of a Taylor bubble would be blunter if the surface tension was increased. This was because the surface tension affected the Froude number, controlling the flow around a Taylor bubble. The simulation results were also compared with the Taylor bubble shape, created by the Dumitrescu-and-Taylor model and former studies in order to ensure that they were consistent. Finally, the empirical model was presented from the simulation results.
Compressible Analysis of Bénard Convection of Magneto Rotatory Couple-Stress Fluid
Authors: Mehta C.B. , Singh M.
Published: March 2018

Thermal Instability (Benard’s Convection) in the presence of uniform rotation and uniform magnetic field (separately) is studied. Using the linearized stability theory and normal mode analyses the dispersion relation is obtained in each case. In the case of rotatory Benard’s stationary convection compressibility and rotation postpone the onset of convection whereas the couple-stress have duel character onset of convection depending on rotation parameter. While in the absence of rotation couple-stress always postpones the onset of convection. On the other hand, magnetic field on thermal instability problem on couple-stress fluid for stationary convection couple-stress parameter and magnetic field postpones the onset of convection. The effect of compressibility also postpones the onset of convection in both cases as rotation and magnetic field. Graphs have been plotted by giving numerical values to the parameters to depict the stationary characteristics. Further, the magnetic field and rotation are found to introduce oscillatory modes which were non-existent in their absence and then the principle of exchange of stability is valid. The sufficient conditions for non-existence of overstability are also obtained.

Published: March 2018

The article discusses motion of a healthy knee joint in the sagittal plane and motion of an injured knee joint supported by an active orthosis. A kinematic scheme of a mechanism for the simulation of a knee joint motion is developed and motion of healthy and injured knee joints are modelled in Matlab. Angles between links, which simulate the femur and tibia are controlled by Simulink block of Model predictive control (MPC). The results of simulation have been compared with several samples of real motion of the human knee joint obtained from motion capture systems. On the basis of these analyses and also of the analysis of the forces in human lower limbs created at motion, an active smart orthosis is developed. The orthosis design was optimized to achieve an energy saving system with sufficient anatomy, necessary reliability, easy exploitation and low cost. With the orthosis it is possible to unload the knee joint, and also partially or fully compensate muscle forces required for the bending of the lower limb.
Effects of Heat Source/Sink and Chemical Reaction on MHD Maxwell Nanofluid Flow Over a Convectively Heated Exponentially Stretching Sheet Using Homotopy Analysis Method
Authors: Sravanthi C.S. , Gorla R.S.R.
Published: March 2018

The aim of this paper is to study the effects of chemical reaction and heat source/sink on a steady MHD (magnetohydrodynamic) two-dimensional mixed convective boundary layer flow of a Maxwell nanofluid over a porous exponentially stretching sheet in the presence of suction/blowing. Convective boundary conditions of temperature and nanoparticle concentration are employed in the formulation. Similarity transformations are used to convert the governing partial differential equations into non-linear ordinary differential equations. The resulting non-linear system has been solved analytically using an efficient technique, namely: the homotopy analysis method (HAM). Expressions for velocity, temperature and nanoparticle concentration fields are developed in series form. Convergence of the constructed solution is verified. A comparison is made with the available results in the literature and our results are in very good agreement with the known results. The obtained results are presented through graphs for several sets of values of the parameters and salient features of the solutions are analyzed. Numerical values of the local skin-friction, Nusselt number and nanoparticle Sherwood number are computed and analyzed.
Simulation of the Flow Through Porous Layers Composed of Converging-Diverging Capillary Fissures or Tubes
Authors: Walicka A.
Published: March 2018

In this paper, a porous medium is modelled by a network of converging-diverging capillaries which may be considered as fissures or tubes. This model makes it necessary to consider flows through capillary fissures or tubes. Therefore an analytical method for deriving the relationships between pressure drops, volumetric flow rates and velocities for the following fluids: Newtonian, polar, power-law, pseudoplastic (DeHaven and Sisko types) and Shulmanian, was developed. Next, considerations on the models of pore network for Newtonian and non-Newtonian fluids were presented. The models, similar to the schemes of central finite differences may provide a good basis for transforming the governing equations of a flow through the porous medium into a set of linear or quasi-linear algebraic equations. It was shown that the some coefficients in these algebraic equations depend on the kind of the capillary convergence.
Filmhefte für den DaF-Unterricht: Qualitätsstandards

Das verstärkte Interesse der letzten Jahre am Film als Unterrichtsmedium hat die Produktion diverser methodisch-didaktischer Lehr-/Lernmaterialien zu Filmen bedingt, jedoch fehlten für Filmhefte, die im Unterricht Deutsch als Fremdsprache eingesetzt werden sollen, fehlen bis dato jegliche Qualitätsstandards. In den Jahren 2014/2015 führte die PH Freiburg in Kooperation mit der Zentralstelle für das Auslandsschulwesen (ZfA) ein Forschungsprojekt zur Entwicklung eines Filmkanons für den DaF-Unterricht im Auslandsschulwesen durch. Zwölf Spielfilme wurden ausgewählt, zu denen nun Filmmaterialien/Filmhefte entwickelt werden sollen. Im Beitrag wird ein Vorschlag zu Qualitätsstandards für die Filmhefte unterbreitet, für die ein dynamischer Kriterienkatalog für die Analyse der Filmhefte formuliert wurde. Mit der Entwicklung des Kriterienkatalogs und der Qualitätsstandards für DaF-Filmhefte werden zwei Ziele verfolgt: 1. Erstellung eines Instrumentariums, welches DaF-Lehrende bei der Beurteilung der Qualität und der Eignung der Filmhefte unterstützen kann; 2. Erstellung eines Instrumentariums, welches Lehrenden bzw. Expertenteams bei der Konzeption und Erstellung von Filmheften als Orientierung dienen kann.
Am I perfect enough to be a true bilingual? Monolingual bias in the lay perception and self-perception of bi- and multilinguals
Authors: Zubrzycki Kamil
Published: March 2018

Little is still known about the factors which make L2 speakers self-categorize as bilinguals and the ways in which bilinguals self-perceive and evaluate their language proficiency. This replicational study aims to contribute to a better understanding of this problem by analyzing linguistic and sociobiographical factors determining self-identification as a bilingual, as well as validating the findings of (Sia, Jennifer & Jean-Marc Dewaele. 2006. Are you bilingual?BISAL1. 1–19). While both studies show that self-assessed overall L2 proficiency and self-rated skill proficiencies (speaking, listening, reading, and writing) have an effect on self-classification as a bilingual, discrepancies were identified in sociobiographical variables, which means that further research is necessary in this area.

The present study was also extended by obtaining qualitative data concerning participants’ definitions of bilingualism and reasons for self-categorizing as bilinguals or not. It was hypothesized that this type of information would shed new light on the results of the original study, which was confirmed by the analysis of the collected responses. The fractional view of bilingualism (Grosjean, François. 1985. The bilingual as a competent but specific speaker-hearer.Journal of Multilingual and Multicultural Development6. 467–477), stemming from the monolingual bias (Cook, Vivian. 1997. Monolingual bias in second language acquisition research.Revista Canaria de Estudios Ingleses34. 35–50), seems to be deeply ingrained in the lay perception of the phenomenon, making bilinguals underestimate and see their skills inaccurately. This indicates that the lay view, drawing extensively on the notion of ideal native speaker as the benchmark, and the current academic approach to bilingualism diverge considerably. It is argued that relevant steps ought to be taken to change the status quo.

Hematology and erythrocyte osmotic fragility of the Franquet’s fruit bat (Epomops franqueti)
Authors: Ekeolu Oyetunde Kazeem , Adebiyi Olamide Elizabeth
Published: March 2018

Background

Hematological parameters are vital diagnostic tools for understanding health dynamics of humans and animals. Franquet’s fruit bat (Epomops franqueti) is host to several parasites such as protozoa, bacteria, viruses and mites. Yet, studies exploring the values of its blood components with interest for research or food purposes are scarce. Thus, this study was carried out to investigate the hematological values of the adult E. franqueti.

Methods

Seventeen (nine female and eight male) apparently healthy adult E. franqueti were captured from their roosting colony. Blood samples were collected for determination of erythrocyte indices [red blood cell count (RBC), packed cell volume (PCV), hemoglobin (Hb) concentration, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC)] and leukocyte indices [total white blood cell counts (WBC), lymphocytes, eosinophil, monocytes, neutrophil count and erythrocytes osmotic fragility].

Results

There were no significant (p≥0.05) sex-related differences in RBC, PCV, Hb concentration, MCV, MCH, MCHC and total and differential WBC of E. franqueti. Erythrocyte osmotic fragility was significantly higher in female than in male E. franqueti at 0.1% NaCl.

Conclusions

These considerations are critical in establishing reference ranges of blood parameters for E. franqueti and may provide insight to why they serve as reservoir hosts for several microorganisms.

Wound healing is a complex restorative process of the altered cutaneous tissue, which is impaired by numerous local and systemic factors, leading to chronic non-healing lesions with few efficient therapeutic options. Stem cells possess the capacity to differentiate into various types of cell lines. Furthermore, stem cells are able to secrete cytokines and growth factors, modulating inflammation and ultimately leading to angiogenesis, fibrogenesis, and epithelization. Because of their paracrine activity, these cells are able to attract other cell types to the base of the wound, improving the formation of new skin layers. Mesenchymal stem cells derived from the adipose tissue, bone marrow, and placenta, offer numerous ways of implementation. The process of harvesting, growing, and administrating stem cells depends on the site and type of the cells, but recent trial results showed improvement of wound healing independent of the administration site. Bioengineered skin substitutes are validated for treatment of chronic wounds with direct application on the skin surface. These offer physical scaffolding for the migrating cells and promote secretion of growth factors, thus facilitating rapid wound healing. Obtaining further clinical data is essential, but stem cell therapy may become a first-line therapeutic choice for the treatment of non-healing chronic wounds.

Published: March 2018

Background:

The prevalence of childhood obesity has significantly increased in Korea. This study aimed to use data from the 2010 Korea National Health and Nutrition Examination Survey (KNHANES) to investigate the association between sodium (Na) intake and insulin resistance in children and adolescents with obesity.

Methods:

The study population consisted of 578 adolescents aged 12–18 years who were enrolled in the 2010 KNHANES. Subjects were classified into the following four groups based on their body mass index (BMI) and homeostatic model assessment-insulin resistance (HOMA-IR) values: normal BMI and HOMA-IR (Group 1), normal BMI and ≥75% HOMA-IR (Group 2), ≥85% BMI and normal HOMA-IR (Group 3) and ≥85% BMI and ≥75% HOMA-IR (Group 4). The groups were further divided into four quartiles (Q1–Q4) based on urinary sodium-creatinine ratios (UNa/Cr) to analyze the association between obesity and metabolic abnormality as a result of increased Na intake.

Results:

There were significant differences among the four groups in terms of abdominal obesity (p<0.000), waist circumference (WC) (p<0.000) blood glucose levels (p<0.000), insulin levels (p<0.000) and UNa/Cr, with Groups 2, 3 and 4 having significantly higher UNa/Cr than Group 1 (p=0.002). In addition, there was a significant positive correlation between UNa/Cr and obesity (Q1=1 vs. Q4=3.23, p=0.019) and metabolic abnormality (Q1=1 vs. Q4=2.25, p=0.167).

Conclusions:

Increased Na intake showed a positive statistical correlation with insulin resistance and is associated with an increased risk of insulin resistance and other metabolic abnormalities in obese children and adolescents.

Published: March 2018

Background

Hand grip strength (HGS) test is commonly used as an indicator of overall muscle strength in medical and sport practices. Recently, several studies have proposed that the measurement of the maximal HGS depends on dynamometer’s handle position. The aim of the present study was to identify the optimal handle position to obtain maximal HGS using the hand grip dynamometer (HGD) for school-aged children.

Methods

HGS was assessed with the Jamar digital HGD. Each participant performed three maximum contractions of each hand on three handle positions progressing from first to third position.

Results

A total of 135 healthy children aged 5–9 years participated in the study. Participants obtained significantly higher results using position 2 than using positions 1 or 3. The maximal mean (± SD) HGS achieved was 9.9 (± 3.1) kg with position 1, 10.4 (± 3.1) kg with position 2, and 9.0 (± 3.2) kg with position 3. Handle position 2 was the most comfortable position for 73% of participants.

Conclusions

Our results provide useful methodological information indicating that the second handle position of the Jamar digital HGD is optimal to measure maximal HGS in non-athletic healthy pediatric participants aged 5–9 years.
Polarization and EIS studies to evaluate the effect of aluminum concentration on the corrosion behavior of SAC105 solder alloy

This paper presents an investigation on corrosion behavior of Sn-1.0Ag-0.5Cu-XAl (X = 0, 0.1, 0.5, 1.0) by means of polarization and electrochemical impedance spectroscopy (EIS) measurements in 3.5 wt.% NaCl solution. The results show that addition of aluminum into SAC105 shifts the corrosion current density and passivation current density towards more positive values. It is also found that with an increase in aluminum concentration in SAC105 solder alloy, the corrosion current density increases and polarization resistance decreases. This suggests that SAC105 with the highest concentration of Al has the lowest corrosion resistance. In this case, the corrosion behavior seems to be attributed to anodic dissolution of aluminum and Sn-matrix.

Published: March 2018

Microstructure and dielectric properties of La2O3doped Ti-rich barium strontium titanate ceramics, prepared by solid state method, were investigated with non-stoichiometric level and various La2O3content, using XRD, SEM and LCR measuring system. With an increase of non-stoichiometric level, the unit cell volumes of perovskite lattices for the single phase Ti-rich barium strontium titanate ceramics increased due to the decreasing A site vacancy concentration V″A. The unit cell volume increased and then decreased slightly with the increasing La2O3content. Relatively high non-stoichiometric level and high La2O3content in Ti-rich barium strontium titanate ceramics contributed to the decreased average grain size as well as fine grain size distribution, which correspondingly improved the temperature stability of the relative dielectric constant. The relative dielectric constant єrRT, dielectric loss tanδRTand the maximum relative dielectric constant єrmaxdecreased and then increased with the increasing non-stoichiometric level. With the increase of La2O3doping content, the relative dielectric constant єrRTincreased initially and then decreased. The maximum relative dielectric constant єrmaxcan be increased by applying low doping content of La2O3in Ti-rich barium strontium titanate ceramics due to the increased spontaneous polarization.
Aggregation kinetics of irreversible patches coupled with reversible isotropic interaction leading to chains, bundles and globules
Authors: Malhotra Isha , Babu Sujin B.
Published: March 2018

In the present study we are performing simulation of simple model of two patch colloidal particles undergoing irreversible diffusion limited cluster aggregation using patchy Brownian cluster dynamics. In addition to the irreversible aggregation of patches, the spheres are coupled with isotropic reversible aggregation through the Kern–Frenkel potential. Due to the presence of anisotropic and isotropic potential we have also defined three different kinds of clusters formed due to anisotropic potential and isotropic potential only as well as both the potentials together. We have investigated the effect of patch size on self-assembly under different solvent qualities for various volume fractions. We will show that at low volume fractions during aggregation process, we end up in a chain conformation for smaller patch size while in a globular conformation for bigger patch size. We also observed a chain to bundle transformation depending on the attractive interaction strength between the chains or in other words depending on the quality of the solvent. We will also show that bundling process is very similar to nucleation and growth phenomena observed in colloidal system with short range attraction. We have also studied the bond angle distribution for this system, where for small patches only two angles are more probable indicating chain formation, while for bundling at very low volume fraction a tail is developed in the distribution. While for the case of higher patch angle this distribution is broad compared to the case of low patch angles showing we have a more globular conformation. We are also proposing a model for the formation of bundles which are similar to amyloid fibers using two patch colloidal particles.
Aretalogical Poetry: A Forgotten Genre of Greek Literature
Authors: Lipka Michael
Published: March 2018

The article deals with a hitherto largely neglected group of poetic texts that is characterized by the representation of the vicissitudes and deeds of a single hero (or god) through a third-person omniscient authorial voice, henceforth called ‘aretalogical poetry’. I want to demonstrate that in terms of form, contents, intertextual ‘self-awareness’ and long-term influence, aretalogical poetry qualifies as a fully-fledged epic genre comparable to bucolic or didactic poetry. In order not to blur my argument, I will focus on heroic aretalogies, and onHeracleidsandTheseidsin particular, because of their prominence in the minds of ancient literary critics. In the case of Heraclean aretalogies, it is expedient to distinguish further between aretalogies of ‘epic’ and ‘lyric epic’ (i.e. lyric poets such as Stesichorus, who writes ‘epic’ aretalogies).

Die Gesundheitsversorgung von Migranten erfordert von den beteiligten Gesundheitsberufen neben fachlichem Wissen auch Kultursensibilität. Diese wird in der Ausbildung und im beruflichen Alltag nicht systematisch vermittelt. Das Programm „Operation Team – Interprofessionelle Fortbildungen“ der Robert Bosch Stiftung bietet eine Möglichkeit, kultursensible Lerneinheiten in multiprofessionellen Lern- und Weiterbildungssettings zu etablieren. Viele Institutionen nutzen das Angebot aktiv.
‚Blanko-Verordnung‛ und ‚Direktzugang‛ – zwei Wege zu mehr Entscheidungsautonomie für die therapeutischen Gesundheitsfachberufe
Authors: Räbiger Jutta , Schmidt Wiebke
Published: March 2018

Das bestehende System der engen gesetzlichen Regelung (Heilmittel-Richtlinie) und die damit verbundene Abhängigkeit von detaillierten ärztlichen Verordnungen haben auf Seiten der Therapeuten, insb. der Physiotherapeuten, zu der Forderung nach mehr Therapiefreiheit geführt. Derzeit sind zwei Systeme in der Diskussion, die den Heilmittelerbringern mehr Freiheit bei der Wahl von Art, Menge und Dauer der Behandlung bieten könn(t)en: Die ‚Blanko-Verordnung‛ und der ‚Direktzugang‛, beide Versorgungsformen werden im Folgenden vergleichend betrachtet.
