Authors: Singh Rupinder , Kumar Ranvijay , Amendola A. , Farina Ilenia , Singh Narinder , Fraternali Fernando
Published: October 2019

The present study deals with the optimal design of a Graphene reinforced composite. The Graphene was prepared by chemical exfoliation process and was chemically blended with matrix material in acetone. Further chemically mixed solution was exposed to air for acetone vaporization. Next, this Graphene composite was extruded through twin screw extrusion (TSE) for preparation of feedstock filament with 1.75±0.05mm diameter via fused deposition modelling (FDM). The presented results suggest that statistically controlled Graphene reinforced functional prototypes can be usefully employed as sensors for bio-medical and engineering applications.

Authors: Lascu Anca , Fagadar-Cosma Eugenia
Published: October 2019

The purpose of this work was to determine whether novel hybrid nanomaterials obtained in mild synthesis conditions between a Pt (II) metalloporphyrin, namely: Pt (II) 5,10,15,20-tetra (4-methoxy-phenyl)-porphyrin (PtTMeOPP) and nanoGold (n-Au) offer better recognition or detection properties toward hydrocortisone than the solely uncombined compounds. The Pt-porphyrin, gold-colloid and the hybrid nanomaterials were synthesized and characterized by UV-vis, FT-IR,1H-NMR, AFM and TEM microscopy. For the concentrations of hydrocortisone that have relevance for medical field, covering the range of 10-8to 10-7M, an excellent correlation of 0.99 was obtained between the intensity of absorption of then-Au-PtTMeOPPhybrid plasmon and the hydrocortisone concentration, measured in THF-water system. So, thisn-Au-PtTMeOPPconjugate system can be further developed to implement an accurate hydrocortisone optical sensor.
Scalability of Copper-Interconnects down to 3μm on Printed Boards by Laser-assisted-subtractive process
Authors: Acharya Sarthak , Chouhan Shailesh Singh , Delsing Jerker
Published: October 2019

As per the latest roadmap of iNEMI, the global electronics market is emphasizing to identify disruptive technologies that can contribute towards denser, robust and tighter integration on the board level. Therefore, reduction in packaging factor of printed board can accommodate greater number of ICs to support miniaturization. This paper has shown an experimental method to pattern the metallic layer on a Printed circuit Board (PCB) to the smallest feature size. To investigate this, a commercially available FR-4 PCB with photosensitive material coat and a Copper (Cu) layer on it, is used. A reverse-mode Laser assisted writing is implemented to pattern the desired copper tracks. Soon after, a well-controlled development and chemical etching of the Laser-activated regions are done using Sodium Hydroxide solution followed by an aqueous solution of Sodium Persulfate. Current PCB interconnects used by the industries are of the order (~20 μm). Whereas the present work is a contribution towards achieving Copper interconnects with feature size 3.0μm. This miniaturization corresponds to 70% reduction in the feature size from 20 μm to 3 μm. The natural adhesion of the Cu layer has remained intact even after the etching, shows the efficiency of the method adopted. Also, variation in the parameters such as etching time, etchant solution concentrations, temaperature, gain and exposure time of Laser beam and their corresponding effects are discussed. Other highlights of this subtractive method includes its cost-efficiency, lesser production time and repeatability.

Authors: Hesari Elham , Sabzi Zahra , Kolagari Shohreh
Published: October 2019

Chronic pain is among problems of old people and causes changes in their life pattern and processes. Teaching palliative care can help old people suffering from chronic pain to live an active life. The aim of this research was to determine effects of educating of palliative care on life pattern of elderly women with chronic pain. The present study was a Quasi-experimental design with pre-test and post test was conducted on 30 elderly women suffering from chronic pain in 2018 in Iran. The Questionnaire for evaluating the Pattern of Life with Pain in the elderly was filled before the intervention, group educating of palliative care was carried out using an educational package, and the questionnaire was completed again immediately and one and three months after. The data was analyzed using mean, standard deviations, Fisher’s F test, and Greenhouse-Geisser and Bonferroni post-hoc test by employing SPSS- 16. Mean changes before teaching palliative care significantly differed from those of immediately and one and three months after the educational program (p = 0.0), (p = 0.004). There were significant differences between the stages of immediately and one month after the educational program and that of three months after it (p = 0.001), (p = 0.002). Concerning the personal life patterns, there were statistically significant differences between the stage immediately after the educational program and those before the intervention and three months after it (p = 0.005), (p = 0.000). Regarding the social life pattern, only the stage of one month after the educational program significantly differed from that of three months (p = 0.005). Mean growth in life pattern of the old women suffering from chronic pain in the stages after the intervention indicated the importance of and the necessity for palliative care during old age. Moreover, the success of this education three months after the educational program as compared to immediately and one month after it indicates that allocation of sufficient time plays a very important role in transferring information and in teaching methods of palliative care to old people.
Le buone ragioni del soggettivismo etico e i suoi errori. Note su bioetica, relativismo e metafisica
Authors: Pessina Adriano
Published: October 2019

Soggettivismo etico e relativismo della conoscenza fanno spesso da sfondo ai dibattiti in bioetica. Il soggettivismo rivendica una sorta di attività legislatrice della ragione umana che, almeno in parte, va accolta. Il singolo uomo ha il dovere di legiferare in merito alla promozione delle finalità che lo interpellano, ma il criterio non può essere soggettivo: per conoscere il bene dell’uomo si deve, infatti, sapere chi è l’uomo. Soltanto nella conoscenza della struttura antropologica umana si può trovare una risposta adeguata alle esigenze del soggetto. Al soggettivismo, allora, si deve rispondere con l’argomento della personalizzazione della vita morale. L’uomo deve realizzare un bene in sé facendolo diventare nel concreto bene per lui. Ma il nodo teorico che resta da affrontare è la possibilità pratica e teorica di rispondere alla domanda “chi è l’uomo” senza fare i conti con la metafisica. Il nesso tra etica e metafisica non si pone secondo la logica della remunerazione o del comando estrinseci, ma come determinazione del senso stesso della condizione umana. La metafisica va pensata come ciò che restituisce alla temporalità il suo stesso significato storico. ---------- Ethical subjectivism and relativism of knowledge are often the setting of debates on bioethics. The subjectivism vindicates a kind of legislative activity of the human reason that, at least partly, must be welcomed. The single man has duty to legislate regarding the promotion of finalities that consult him, but the criterion can not be subjective: to know the good of the man, in fact, ones must know who the man is. A suitable answer to the demands of the subject can be found only in the knowledge of the human anthropological structure. Ones must answer to subjectivism with the matter of the personalization of moral life. The man must realize a good in oneself making it becoming a good for him in the concrete. But the theoretical knot that stays to face is the practical and theoretical possibility to answer to the question “who is the man” without making the accounts with the metaphysics. The connection between ethics and metaphysics doesn’t set according to the logic of the extrinsic remuneration or the command, but as determination of the sense itself of human condition. Metaphysics must be thought like what it returns its same historical meaning to temporality.
The child with haemophilia
Authors: Karabus C. D.
Published: October 2019

Haemophilias are bleeding disorders due to an inherited defect in production of clotting factors. In South Africa 867 haemophiliacs have been registered and 309 of these are boys under 15 years of age. Haemophilia A and B make up about 85-90% of all cases. They are inherited in a sex-linked manner and thus affect males only. The manifestations of haemophilia are due to bleeding characteristically involving the joints. The disorder varies in severity and in the most severely affected children, repeated hemarthroses may lead to crippling. Early administration of clotting factor, preferably given at the child’s home, physiotherapy to prevent muscle wasting and regular assessment by a co-ordinated team of paediatrician, physiotherapist, orthopaedic surgeon and dentist at the hospital are necessary for successful management. These facilities can be organised only at a comprehensive haemophilia treatment centre treating a large number of bleeders.
Cystic fibrosis and the role of the physiotherapist
Authors: Miot Anne , Pettifor J. M. , Reef I.
Published: October 2019

Cystic fibrosis is an inherited disease, the major problems being pancreatic malabsorption and progressive respiratory involvement, although numerous other organs may also be involved. The pulmonary pathology and the role of the physiotherapist in the treatment of cystic fibrosis is discussed. The physiotherapist plays an important role in the management of the child with cystic fibrosis, not only from the point of view of maintaining maximal pulmonary function but also because she comes into close contact with the family and can help in optimising the acceptance of the child into the family situation.

Positive Definiteness on Products of Compact Two-point Homogeneous Spaces and Locally Compact Abelian Groups
Authors: Menegatto V. A. , Oliveira C. P.
Published: October 2019

In this paper, we consider the problem of characterizing positive definite functions on compact two-point homogeneous spaces cross locally compact abelian groups. For a locally compact abelian group $G$ with dual group $\widehat{G}$, a compact two-point homogeneous space $\mathbb{H}$ with normalized geodesic distance $\unicode[STIX]{x1D6FF}$ and a profile function $\unicode[STIX]{x1D719}:[-1,1]\times G\rightarrow \mathbb{C}$ satisfying certain continuity and integrability assumptions, we show that the positive definiteness of the kernel $((x,u),(y,v))\in (\mathbb{H}\times G)^{2}\mapsto \unicode[STIX]{x1D719}(\cos \unicode[STIX]{x1D6FF}(x,y),uv^{-1})$ is equivalent to the positive definiteness of the Fourier transformed kernels $(x,y)\in \mathbb{H}^{2}\mapsto \widehat{\unicode[STIX]{x1D719}}_{\cos \unicode[STIX]{x1D6FF}(x,y)}(\unicode[STIX]{x1D6FE})$, $\unicode[STIX]{x1D6FE}\in \widehat{G}$, where $\unicode[STIX]{x1D719}_{t}(u)=\unicode[STIX]{x1D719}(t,u)$, $u\in G$. We also provide some results on the strict positive definiteness of the kernel.

La spécialisation vétérinaire : la situation française en 2017
Authors: Coppalle Jérôme , Couvidat Danièle
Published: October 2019

La spécialisation est un processus évolutif qui a accompagné l’avancée des connaissances dans les différents domaines de l’exercice professionnel vétérinaire. Initialement créé en 1992, la spécialisation vétérinaire consiste d’abord en une approche par la formation, accessible à compter de 2004 par validation des acquis de l’expérience. En 2008, une évolution majeure organise la spécialisation autour d’une liste de spécialités arrêtée par le ministre chargé de l’agriculture après avis du Conseil national de la spécialisation vétérinaire. Il s’agit de passer d’un paradigme de spécialisation à partir de formations à un paradigme de spécialités conférées à des titulaires de compétences, diplômes et expériences professionnelles certifiées. La spécialisation vétérinaire en France en 2017 pose encore un certain nombre de questions notamment en ce qui concerne l’évolution de la réserve d’emplois, le positionnement de la spécialisation française face aux collèges américains, les exigences accrues en termes d’impartialité et le modèle économique à envisager pour l’avenir.
Hypertypes canins : propositions pour une stratégie d’évictionille
Authors: Chaudieu Gilles
Published: October 2019

Le phénotype de nombreux chiens ne correspond pas à celui de leur standard, qui devrait définir l’archétype racial idéal, notamment dans des populations canines en vogue. En élevage, une sélection globale en consanguinité large est la règle, la consanguinité étroite devant rester exceptionnelle. A partir de cette situation, la sélection dans la race doit s’appuyer sur un standard bien rédigé et correctement interprété. L’émergence d’hypertypes au sein des deux structures devrait être contenue par de bonnes pratiques d’élevage et un encadrement strict de la politique de sélection des associations de races. La profession vétérinaire, à différents niveaux -praticiens, sociétés savantes, institutions -souffre d’un déficit d’implication et de faire-savoir dans la lutte contre la production d’hypertypes canins ; certaines mesures simples devraient permettre de modifier les comportements des responsables de la filière, des éleveurs, des juges, des vétérinaires, du public, et de ce fait réduire les effets néfastes de comportements gravement préjudiciables à la santé et au bien-être du chien de race.
La sélection dans l’espèce bovine et ses perspectives
Authors: Boichard Didier , Mattalia Sophie , Fritz Sébastien
Published: October 2019

Cet article présente la sélection bovine dans les deux filières bovines laitière allaitante qui ont chacune leurs particularités, en particulier la place de l’insémination animale ou le développement de la base de sélection, mais aussi des propriétés communes, pour la plupart issues de la Loi sur l’Élevage qui a défini l’organisation de la sélection. Progressivement, les objectifs de sélection ont évolué vers la prise en compte d’un nombre croissant de caractères et la diminution du poids de la productivité au profit des caractères fonctionnels. La Loi d’orientation agricole de 2006 et l’émergence de la sélection génomique à partir de 2009 ont profondément modifié l’organisation de la sélection avec l’abandon du testage sur descendance, la mise en place de populations de référence, la concentration des acteurs économiques, une mutualisation nationale moindre au profit d’initiatives d’entreprises mais aussi d’accords internationaux. Un nouveau changement majeur est attendu avec la mise en application en 2018 du Règlement Zootechnique Européen qui modifie le cadre organisationnel de la sélection.
Hypertypes et standards de races chez le chien : une histoire d’équilibre
Authors: Guintard Claude , Class Anne-Marie
Published: October 2019

L’hypertype dans l’espèce canine a fait l’objet de nombreuses réflexions et publications mais l’originalité de ce travail réside dans le fait qu’il associe deux visions complémentaires, à savoir celle du juge et de l’éleveur d’un côté et celle de l’anatomiste et du vétérinaire de l’autre. Si en exposition canine, le culte du beau, poussé à l’exagération, pourrait prendre le pas sur la fonctionnalité ; on peut se demander quels sont les outils qui permettent d’éviter ces phénomènes préjudiciables pour le bien-être, voire la santé des chiens produits. Le levier du standard est souvent mis en avant, on peut toutefois se demander si ce n’est pas l’interprétation qui en est faite (voire la non lecture minutieuse des standards parfois) plus que les standards eux-mêmes qui est à l’origine de ce phénomène. La rédaction des standards actuels, selon le modèle de la Fédération Cynologique Internationale (FCI), ne devrait pas pouvoir aboutir à des hypertypes ; tout est question d’appréciation et d’équilibre de la part des différents acteurs de la cynophilie. D’autres outils que les standards sont clairement utilisables pour combattre les hypertypes, les auteurs ne feront que les énoncer, sans les développer.
Spatial soil loss estimation using an integrated GIS-based revised universal soil loss equation (RUSLE) in selected watersheds in northern Ghana
Authors: Adongoa T.A. , Agyare W.A. , Abagalec F.K. , Kyei-Baffour N.
Published: October 2019

This study used thespatially integrated RUSLE to estimate annual soil loss and spatial distribution of soil loss severity classes for nine (9) reservoir  catchments in northern Ghana.This model is an empirical model with five (5)main input parameters: rainfall erosivity, soil erodibility, slope  length/steepness, landcover management and erosion management practice factors. Estimated annual soil loss rate ranged from 0 – 96.30 t/ha/y. Estimated mean annual soil loss ranged from 3.71 – 8.17 %. The severity of annual soil loss rates ranged from very low class (0.0 – 1.0 t/ha/y) to very high class (> 60.0 t/ha/y). Across the nine (9) catchments, the very low soil loss severity class was noted to constitute a larger portion of between 36.70 to 67.50 %. The moderate soil severity class was noted as the highest contributor to total annual soil loss. Soil and water conservation measures are required in the watershed to reduce soil loss.

Teatralidades da linguagem e poesia contemporânea
Authors: Scramim Susana
Published: October 2019

Este artigo pretende discutir os processos de nomeação operados pela escrita contemporânea, especialmente, no trabalho de duas poetas, Paula Glenadel e Nathalie Quintane, em seus livros respectivamente, A fábrica do feminino (2008) e Chaussure (1997). Serão tomados em consideração nesta reflexão os gestos que formulam definições, aplicam atributos, criam tropismos e, simultaneamente, os desconstroem, na medida que colocam o próprio processo de nomeação em xeque nessa experiência de escrita. Com isso, se estabelece uma relação entre voz (querer dizer) e linguagem (ser obrigado a dizer) que implica o enfrentamento de uma das formulações mais radicais da poesia moderna, a saber, reelaborar a relação entre a escrita da poesia – do verso – e a produção de um pensamento que se mantenha ético. Esse processo de nomeação e renomeação será denominado aqui de teatralidades da linguagem.
Quase-teatro: o pensamento escrita de Paula Glenadel
Authors: De Medeiros Manuela Quadra
Published: October 2019

O último livro da escritora contemporânea Paula Glenadel, intitulado Rede (2014) é classificado, em sua ficha catalográfica, como poesia, mas é escrito em forma de peça de teatro. A própria autora refere-se ao trabalho do livro, em diferentes momentos, como “prosa poética teatralizada” e como um trabalho de “pensamento-escrita”. Diante dessa classificação escorregadia, característica cada vez mais comum da poesia contemporânea – considerada como um desdobramento da crise da poesia moderna – pensamos a escrita de Paula Glenadel como um quase-teatro em que o que está em jogo é a própria linguagem colocada em cena, ou a linguagem teatralizada. Para isso, partimos do pensamento de Jacques Rancière acerca do “teatro imóvel”, que seria uma nova ideia de pensar o teatro como um teatro sem ação.
Effect of Pressure Gradient on the Development of Görtler Vortices
Authors: Marochio Fernandes Leandro , Teixeira de Mendonça Marcio
Published: October 2019

Boundary layers over concave surfaces may become unstable due to centrifugal instability that manifests itself as stationary streamwise counter rotating vortices. The centrifugal instability mechanism in boundary layers has been extensively studied and there is a large number of publications addressing different aspects of this problem. The results on the effect of pressure gradient show that favorable pressure gradients are stabilizing and adverse pressure gradient enhances the instability. The objective of the present investigation is to complement those works, looking particularly at the effect of pressure gradient on the stability diagram and on the determination of the spanwise wave number corresponding to the fastest growth. This study is based on the classic linear stability theory, where the parallel boundary layer approximation is assumed. Therefore, results are valid for Görtler numbers above 7, the lower limit where local mode linear stability analysis was identified in the literature as valid. For the base flow given by the Falkner-Skan solution, the linear stability equations are solved by a shooting method where the eigenvalues are the Görtler number, the spanwise wavenumber and the growth rate. The results show stabilization due to favorable pressure gradient as the constant amplification rate curves are displaced to higher Görtler numbers, with the opposite effect for adverse pressure gradient. Results previously unavailable in the literature identifying the fastest growing mode spanwise wavelength for a range of Falkner-Skan acceleration parameters are presented.
The Female Body in the Looking-Glass
Authors: Sliwinska Basia
Published: October 2019

In his writing on the 'mirror stage', the psychoanalytic theorist Jacques Lacan describes the female body as lacking: a mere symptom of man, an object constructed by male desire. However, what happens if the woman in art follows Jean Baudrillard's advice to 'swallow the mirror', and is made real? What if the beautiful is inverted and becomes ugly; and the ugly becomes beautiful? These are the fundamental questions Basia Sliwinska poses in this important new enquiry into gender identity and the politics of vision in contemporary women's art. Through an innovative discussion of the metaphor of the mirror, or looking-glass, Sliwinska reveals how the post-1989 practices of woman artists from both sides of the former Iron Curtain - such as Marina Abramovic, Joanna Rajkowska, Lora Hristova, Jess Dobkin, Natalia LL, Sedzia Glowny and SZ-ZS - go beyond gender binaries and instead embrace otherness and difference. She makes a refreshing, radical intervention into art theory and cultural studies by offering concepts such as 'the mirror' and 'genderland' (inspired by Alice's 'Wonderland') as critical tools with which we can analyse and explain recent developments in women's art.
Dialogic Discourse Analysis: A methodology for dealing with the classroom as a text
Authors: Skaftun Atle
Published: October 2019

Bakhtin is a source of theoretical inspiration for educational research. This article will be an attempt to activate also Bakhtin’s analytical practice and his methodology. I will explore and elaborate the typology of discursive relations which are suggested in Bakhtin’s book on Problems of Dostoevsky’ Poetics (Bakhtin ,1984), and the potential application of it in the study of discourse in the classroom. In order to do so properly it will be necessary to activate Bakhtin’s understanding of the utterance as a meaningful unity, and thus also the problem of authorship and the relationship between author and hero.Bakhtin’s analytical practice can be considered a consistent methodology for the study of literature in schools as well as in the scholarly study of literature (cf. Skaftun, 2009; 2010), and I have called it dialogic discourse analysis (DDA). The first main part of the article elaborates key features of DDA in dialogue with Bakhtin’s work. In the other main part, DDA is applied to educational settings in order to enter the educational dialogue on how to make sense of authorship and the adhering conception of the classroom as a text. My ambition here is primarily to elaborate DDA as a powerful and dynamic toolkit also for educational research. In doing so I also hope to contribute to the ongoing work of transferring Bakhtin’s dialogism as a whole from the study of literature to the study of education. Examples will in part be drawn from literature, but for the most part from educational settings.

Authors: Zafiri Makrina , Vakalopoulou Vassiliki , Pliogou Vassiliki
Published: October 2019

In recent years, dyslexia has become an important issue in the field of foreign language teaching and learning. In this research we will explore dyslexia in connection to teaching and learning a foreign language. More particularly, in this research, we will be probing into the teaching of German as a foreign language. The purpose of this research is to investigate the effectiveness of the application of Differential Instruction, the application of the Grammar –Translation Method, the Audio-Visual Method, the Communicative Approach to language teaching as well as the Multisensory Method to a Greek student with dyslexia. The girl is in the first year of junior high school and is being taught German as a foreign language at school. The research method, which was applied, focused on qualitative research through the use of semi - structured interviews. This research is also a case study. Action research was conducted, for the needs of this small-scale research, through ten differentiated instruction lessons which were taught to a student with dyslexia. The student and her mother were the major sources of data collection. More particularly, the semi - structured interviews were conducted before and after the implementation of differentiated instruction with the student and her mother. We initially attempted to collect information through semi-structured interviews, on the student's family profile, and after conducting the ten lessons, we tried to verify the effectiveness of the approaches and methods which were applied. The results of this research showed that the effectiveness of differentiated instruction was immense as the student’s performance improved in the foreign language.
Effect of Hot Air Thin Layer Drying Temperature on Physicochemical and Textural Properties of Dried Horseradish
Authors: Mitra Pranabendu , Alim Md. Abdul , Meda Venkatesh
Published: October 2019

The horseradish (Armoracia rusticana) is an important crop as ingredients for many commercial food products and medicinal uses. However, the horseradish is perishable and preservation of this crop for supplying year-round is necessary. Drying can be used to preserve the horseradish but establishing a suitable drying method and conditions are important for product quality of dried horseradish. The objective of this study was to investigate the effects of hot air-drying temperatures on the physicochemical and textural properties of dried horseradish samples to determine the appropriate hot air-drying conditions. The sliced horseradish samples were dried at 55, 65, 75, 85 and 95 ℃ using a conventional hot air drier. The physicochemical and textural properties of the dried horseradish samples were determined, and the results were compared for different drying temperatures. The ANOVA analysis indicated that the drying temperature affected the physicochemical and textural properties of dried horseradish samples significantly (p<0.05). The experimental results indicated that the moisture content (9.18-6.15%,wb), aw (0.06-0.03), porosity (31.47-12.13%) and rehydration ratio (82.74 -44.47%) decreased and piece density (0.63-0.84 g/mL), hardness (193.63 -298.31N), cohesiveness (1.04-1.32), gumminess (202.13-390.12) and chewiness (635.08-1223.55) of dried horseradish samples increased with the drying temperature. Power law model indicated that the porosity was linearly corelated to the rehydration ratio of dried horseradish samples. The overall results revealed that relatively lower (55-65 ℃) drying temperature range was suitable to keep the quality of the dried horseradish samples. The findings of this study are expected to be helpful for the commercial drying of horseradish samples using hot air-drying method.
Endogenous Tradability, International Relative Prices, and the International Transmission of Business Cycles
Authors: Moon Soojae
Published: October 2019

This paper propose a two-country, dynamic, stochastic, general equilibrium (DSGE) model with endogenous tradability, product differentiation, variously determined physical capital, and an elastic labor supply to explore the propagation of business cycles across countries. The model successfully addresses international relative price dynamics (its appreciation with positive home productivity shock, called the ‘Harrod-Balassa-Samuelson Effect’) through the entry of producers and their cut-off productivities of exporting. The use of endogenous physical capital in the model induces a more realistic framework since the simulated model is compared to the U.S. investment data that covers spending on capital equipment, structures and inventories for producers’ entry and exit dynamics. Building the model with endogenous capital and elastic labor supply weakens the volatility of investment compared to conventional international real business cycle (IRBC) models. The model also accounts for several features of the data, such as the volatility of aggregate variables and their correlations with GDP.
The Stature of Volunteers to the Polish Army in France: An Anthropometric Inquiry
Authors: Kopczyński Michał , Antosik Szymon
Published: October 2019

This article analyzes the stature of volunteers to the Polish Army in France examined in Recruitment Center no. 2 in Chicago in 1917 and 1918. The authors divided the sample according to place and time of birth and compared the statures of volunteers with heights of Polish draftees measured by conscription authorities in Poland. The investigation arrives at two main conclusions. Firstly, Poles born in the US were considerably taller than both volunteers born in Poland and draftees living in the native country. Secondly, the comparison of immigrants and those who remained in Poland shows that people who migrated were taller than those who remained, although the difference diminished over time. Since human stature is positively correlated with length of life and work capacity, we can conclude quoting the opinion of the Dillingham Commission: Although drawn from classes low in the economic scale, the new immigrants as a rule are the strongest, the most enterprising, and the best of their class.

The results of the study will be useful for firms through enables firms to know what factors are influence their stock market liquidity. Further, this study could have implications on regulating bodies such as Bursa Malaysia to help design regulations that could enhance stock market liquidity. Moreover, this study would provide implications for the investors and traders in terms of helping them on how to formulate their trading strategy.
An Investigation of the Psychometric Properties of Emotional Intelligence Scale Using Item Response Theory
Authors: Aldhafri Said , Shindi Yousef Abu
Published: October 2019

Students’ emotional intelligence represents an important variable that is connected to students’ academic achievementand life success. One main challenge when measuring students’ emotional intelligence is to have a valid and reliablemeasure that captures this emotional construct. The current study aims to investigate the psychometric properties of theArabic version of Alsmadoni emotional intelligence scale (AEIS-25) using item response theory (IRT) models. Thestudy was applied among 3030 students in grades 7-10 in Oman.Data model fit was examined through evaluating IRT assumptions (i.e. unidimensional assumption and localindependence assumption) and goodness of fit (i.e. items fit and persons fit). It was found that item parameters wereacceptable and satisfactory, which indicates the appropriateness of AEIS to examine emotional intelligence amongadolescents. Findings from exploratory factor analysis for 2924 students and for the remaining 24 items indicated thepresence of a 2-factor model since the third factor was loaded by only one item. AEIS was considered as a reliable andpotentially valid measure of trait emotional intelligence.

Zinc borosilicate glass with optimized chemical composition was synthesized and doped with 5 wt % α-Fe2O3. XRD, 57Fe Mössbauer, FT-IR, UV/Vis/NIR and FE SEM were used as the characterization methods. XRD showed the amorphous nature of the samples synthesized. 57Fe Mössbauer spectra confirmed the superposition of Fe3+ in tetrahedral and Fe2+ in octahedral positions. FT-IR spectra showed general features characteristic of different borosilicate glasses. The NIR band at 1116 nm in the UV/Vis/NIR spectrum was assigned to the Fe2+ transition, whereas the Fe3+ transition bands could not be assigned due to the overlapping of several spectral bands of different origin in the UV region centered at 282 nm and the Vis region between 415 to 496 nm. Zinc borosilicate glass as synthesized can be considered as a possible matrix in the immobilization of nonradioactive as well as radioactive wastes.
Expectancy-Value Theory of Achievement Motivation: How Perceived Racial Prejudice Can Influence Ability Beliefs, Expectancy Beliefs and Subject Task Value of Métis Post-Secondary Students
Authors: Ferguson Leon Myles
Published: October 2019

To explore how the threat of prejudice can interfere with a learner’s ability beliefs, expectancies of success and subjective task value 165 Métis post-secondary students were asked to consider themselves applying for a job with a non-Indigenous employer. Participants were grouped into high and low Métis identifiers and then placed into one of three groups: (1) Employer-prejudiced, (2) Employer non-prejudiced, and (3) Employer’s attitudes about Indigenous peoples unknown. A 2x3 Analysis of Variance (ANOVA) was used to examine the relationship between Métis identity (high/low) and five concepts: (1) expectations about being hired, (2) value placed on being hired, (3) learners’ beliefs about the mock employer’s integrity, (4) the extent to which learner’s held negative over-generalized negative beliefs about non-Indigenous people, and (5) actual task performance. Although there were no interaction effects a number of main effects are reported. While students with a stronger sense of Métis identity reported more overall optimism about being hired that those learners with a weaker sense of Métis identity, they nevertheless reported less motivation to perform an assigned task to the best of their respective abilities. Students in the prejudiced condition reported lower expectations about being hired and less motivation to perform the assigned task to the best of their ability. Students in the prejudiced condition also reported stronger negative generalized beliefs about both the mock employer and non-Indigenous people in general. Although the students in the prejudiced condition reported less motivation to exert high effort on the assigned task, their actual performance on the task was not related to whether or not the hypothetical employer was described as prejudiced, non-prejudiced, or neither about Indigenous peoples. Future studies should explore how one’s sense of Métis identity and other minority group identity can influence reactions to a threatening academic environment and suppress academic motivation.

Published: October 2019

Ion-exchange (number of functional group) properties and swelling capacity of leaf cell walls of plant species Betula nana, Salix polaris, Dryas octopetala and Cassiope tetragona from Western Spitsbergen Island were investigated. It was found out that cell wall of Arctic plants is cation exchanger which has similar functional groups (amine groups, carboxyl groups and phenolic OH-groups) with cell wall of boreal plants. In all investigated species, the highest percentage in the structure of the cell wall was recorded for the carboxyl groups of hydroxycinnamic acids and phenolic OH-groups, which are part of phenolic compounds. In comparison with species from other climatic zones leaf cell wall of arctic plants has in 2–3 times higher amount of ion exchange groups of all types as well as the higher values of swelling coefficients. It was proposed that the high values of the ion-exchange capacity and swelling coefficient of the cell wall of all studied species contribute to greater water flow system by the apoplast and enhance the metabolic processes in the cell wall of plants at high latitudes.
Oxygen evolution rate in Antarctic filamentous alga Stigeoclonium sp. evaluated by optodes relates to chlorophyll fluorescence parameters (Short Communication)
Authors: Váczi Peter
Published: October 2019

Photosynthetic reactions of algal communities, the essential component of primary production in polar regions, are strongly dependent on environmental factors. Among them, availability and amount of light in particular parts of growing season are of major importance. In this paper, the response of the photosynthetic processes of a filamentous fresh-water alga to photosynthetically active radiation (PAR) was studied by two approaches. The simultaneous measurements of the effective quantum yield (FPSII) and oxygen evolution rate (OER) at stepwise increasing photosynthetically active radiation provided data for beneficial correlation analysis of the FPSII to OER relationship in a wide range of PAR. In this study, the culture of filamentous alga Stigeoclonium sp. was analyzed. The linear relationship between FPSII and OER was found for the low PAR (the range of 0 – 200 mmol.m-2.s-1). At high PAR levels (200 – 1000 mmol.m-2.s-1) another linear relationship with different slope was found. The approach combining the fluorometric and oxymetric method might be used for calibration of data in follow up studies and, consequently for evaluation of photosynthetic rates (O2 evolution) from chlorophyll fluorescence data.

Authors: Vasilevskaya Natalia Vladimirovna , Domakhina Anna Dmitrievna
Published: October 2019

This article presents data of palynological research of Larix sibirica Ledeb. (Pinaceae Lindl) in the Arctic climate of Murmansk city, located in the Far North of Russia. The purpose of this study is to research the teratogenesis of the Larix sibirica pollen in the conditions of the Arctic climate and technogenic pollution of the city of Murmansk and holding the palynoindication of the environment. In the tested samples of pollen of L. sibirica, five morphological anomalies of the development were defined: pollen without protoplast, with plasmolysed protoplast, with damaged exine, giant pollen grains and dwarfed. The proportion of teratomorphs in the samples varies from 76 to 81%, which is above the control values of 2.5 – 3 times. Most of the abnormal grains are represented by pollen with plasmolysed protoplast (58 – 64%) and without protoplast (11 – 18%). Giant, dwarf pollen grains and pollen with exine damage are much less common. High level of teratogenesis of L. sibirica allows us to draw a conclusion about the critical level of pollution of the city environment.
Diatoms (Bacillariophyta) associated with lichens from Ulu Peninsula (James Ross Island, NE Antarctic Peninsula)
Authors: Chattová Barbora
Published: October 2019

Since 2000, the entire Antarctic diatom flora is being revised using a more fine-grained taxonomy based on a better analysis and interpretation of the morphological and molecular observations. Despite the increased diatom research and efforts, the diversity and ecology of diatoms of lichen inhabiting flora of James Ross Island weren’t studied yet. To reveal the actual diatom diversity, samples were collected during February and March 2018 from lichens on the Ulu Peninsula, James Ross Island, a 2,450 km2 large island, situated in the north-western part of the Weddell Sea, close to the northern tip of the Antarctic Peninsula. The analysis of 29 lichen samples revealed the presence of 56 diatom taxa belonging to 17 genera. The most abundant species were Luticola muticopsis, Hantzschia amphioxys f. muelleri, Pinnularia borealisvar.scalaris, Luticola aff. pusilla and Achnanthes muelleri. Biogeographically, the lichen-inhabiting diatom flora of the Ulu Peninsula is composed of cosmopolitan, Antarctic and endemic elements. The present study is the first focusing on the diversity of lichen-inhabiting diatom communities on James Ross Island, revealing the presence of a rather species rich diatom flora.

Published: October 2019

The anatomical (thickness of layers of fungal and algal symbionts) and ecophysiological parameters (the content of photosynthetic pigments) of two lichen species (Hypogymnia physodes and Umbilicaria hyperborea) from rocky forest communities of northernmost boreal zone (North-West of Russia) were studied. H. physodes is a lichen with foliose thallus morphology and circumpolar distribution which colonizes almost every substrate. U. hyperborea is strictly epilithic lichen with umbilicate type of thallus morphology and arcto-alpine distribution. Despite the fact that the photobiont in two species are closely related taxa (unicellular green algae of the genus Trebouxia) a high variability of photosynthetic pigments content in H. physodes thalli has been revealed, whereas in U. hyperborea, the mycobiotic showed high structural variability. It can be concluded that both mycobiont and photobiont contribute to their adaptation to environmental factors. In the present study it was obtained that the proportion of variation in anatomical structures and the content of photosynthetic pigments probably less depends on taxonomic position of photobiont and more determined by the plasticity of the individual components of the symbiotrophic organism.
Pigment composition, glutathione and tocopherols in green algal and cyanobacterial lichens and their response to different light treatments
Authors: Cempírková Hana , Večeřová Kristýna
Published: October 2019

This study investigated photosynthetic pigments chlorophyll a and b, carotenoids (including xanthophyll cycle pigments) and antioxidants glutathione and tocopherols contents in chloro- (Lobaria pulmonaria, Lasallia pustulata) and cyanolichens (Lobaria scrobiculata, Peltigera canina) from different habitats and of different geographical origin. Lichen thalli were treated with various levels of irradiance (from 100 to 1500 mmol m-2 s-1) for various time periods (from 20 min. to 5 h). The extent of increase of zeaxanthin content after different light treatments differed among chlorolichens, clearly distinguishing the species from light and shade habitats. Irrespective of light treatment, β-carotene content was always higher in cyanobacterial species than in green algal species. Highest canthaxanthin concentration, as well as β-carotene concentration, was found in L. scrobiculata from shade habitat. The content of total glutathione was the same in the same species from different collection sites. On the contrary, contents of a-tocopherol differed in the same species from different collection sites.
Limitation of photosynthetic processes in photosystem II in alpine mosses exposed to low temperatures: Response of chlorophyll fluorescence parameters
Authors: Cameán Yeray Folgar , Barták Miloš
Published: October 2019

In this study, we evaluated the effects of low and sub-zero temperature on the fast chlorophyll fluorescence transient (OJIP) and OJIP-derived parameters in 4 different mosses: Sphagnum girgensohnii, Polytrichum formosum, Hylocomium splendens and Pleurozium schreberi. The low temperature stress was applied on the mosses for 90 min. at 3 different temperatures (5°C, -1°C and -10°C). To investigate the effects of this stress on the functioning of photosystem II (PS II), the chlorophyll fluorescence measurements were taken at control temperature (22°C) and, after a 90 min. acclimation period, at each experimental temperature. The shape of OJIP curves and chlorophyll fluorescence parameters were found temperature-dependent in all the species. The mosses differed in their sensitivity to the stress but general trends in response to low temperature were similar. The results support the idea that S. girgensohnii is less resistant to low temperature stress than the other species. We were also interested in the K and L steps in OJIPs, representing different disorders caused by low temperature. The K-step was seen in P. formosum and P. schreberi and the L-step in H. splendens and S. girgensohnii.
