Sensitivity of the radiative forcing by stratospheric sulfur geoengineering to the amount and strategy of the SO2injection studied with the LMDZ-S3A model
Authors: Kleinschmitt Christoph , Boucher Olivier , Platt Ulrich
Published: February 2018

Abstract. The enhancement of the stratospheric sulfate aerosol layer has been proposed
as a method of geoengineering to abate global warming. Previous modelling
studies found that stratospheric aerosol geoengineering (SAG) could
effectively compensate for the warming by greenhouse gases on the global scale,
but also that the achievable cooling effect per sulfur mass unit, i.e. the
forcing efficiency, decreases with increasing injection rate. In this study
we use the atmospheric general circulation model LMDZ with the sectional
aerosol module S3A to determine how the forcing efficiency depends on the
injected amount of SO2, the injection height, and the spatio-temporal
pattern of injection. We find that the forcing efficiency may decrease more
drastically for larger SO2 injections than previously estimated. As
a result, the net instantaneous radiative forcing does not exceed the limit
of –2 W m−2 for continuous equatorial SO2 injections
and it decreases (in absolute value) for injection rates larger than
20 Tg S yr−1. In contrast to other studies, the net radiative
forcing in our experiments is fairly constant with injection height (in
a range 17 to 23 km) for a given amount of SO2 injected.
Also,
spreading the SO2 injections between 30∘ S and
30∘ N or injecting only seasonally from varying latitudes does not
result in a significantly larger (i.e. more negative) radiative forcing.
Other key characteristics of our simulations include a consequent
stratospheric heating, caused by the absorption of solar and infrared radiation
by the aerosol, and changes in stratospheric dynamics, with a collapse of the
quasi-biennial oscillation at larger injection rates, which has impacts on
the resulting spatial aerosol distribution, size, and optical properties. But
it has to be noted that the complexity and uncertainty of stratospheric
processes cause considerable disagreement among different modelling studies
of stratospheric aerosol geoengineering. This may be addressed through
detailed model intercomparison activities, as observations to constrain the
simulations of stratospheric aerosol geoengineering are not available and
analogues (such as volcanic eruptions) are imperfect.
Module-based structure design of wheeled mobile robot
Authors: Luo Zirong , Shang Jianzhong , Wei Guowu , Ren Lei
Published: February 2018

Abstract. This paper proposes an innovative and systematic approach for synthesizing mechanical structures of wheeled mobile robots. The principle and terminologies used for the proposed synthesis method are presented by adopting the concept of modular design, isomorphic and non-isomorphic, and set theory with its associated combinatorial mathematics. The modular-based innovative synthesis and design of wheeled robots were conducted at two levels. Firstly at the module level, by creative design and analysing the structures of classic wheeled robots, a wheel module set containing four types of wheel mechanisms, a suspension module set consisting of five types of suspension frames and a chassis module set composed of five types of rigid or articulated chassis were designed and generalized. Secondly at the synthesis level, two kinds of structure synthesis modes, namely the isomorphic-combination mode and the non-isomorphic combination mode were proposed to synthesize mechanical structures of wheeled robots; which led to 241 structures for wheeled mobile robots including 236 novel ones. Further, mathematical models and a software platform were developed to provide appropriate and intuitive tools for simulating and evaluating performance of the wheeled robots that were proposed in this paper. Eventually, physical prototypes of sample wheeled robots/rovers were developed and tested so as to prove and validate the principle and methodology presented in this paper.
Una distopía terrorista para el conflicto domínico-haitiano: El día de todos, de Juan Carlos Mieses
Authors: Martín de Marcos Gonzalo
Published: February 2018

El día de todos (2014) es una novela distópica escrita por el dominicano Juan Carlos Mieses. En la historia, Haití y la República Dominicana se abocan a un choque apocalíptico. Un acto terrorista cruento de un líder mesiánico es el detonante. El conflicto domínico-haitiano se trata en la figura de personajes de una y otra nación. La relación con el otro—según el enfoque de Tzvetan Todorov—y el esencial nihilismo de todo terrorismo—tal como lo argumenta André Glucksmann— sirven para estudiar una ficción que no asume un compromiso explícito con uno u otro lado, sino que deriva la reflexión sobre el problema al plano de la figuración literaria.

La redención en la novelística de H. A. Murena
Authors: Santana Hernández Daniel
Published: February 2018

H. A. Murena cultivó una novelística propia de su labor ensayística. Aunque parece clara la división en dos etapas de sus siete novelas, el conjunto de la prosa de ficción sigue una línea con afán escatológico: vencer el nihilismo pasa por anegarnos en él, sin perder de vista una particular noción de verdad soteriológica. La reflexión de Walter Benjamin en torno a la felicidad y la redención servirá de pilar maestro en el recorrido por las novelas del autor argentino.
Más allá de la frontera: adscripciones contextuales de la obra de Eduardo Milán
Authors: López Carballo Pablo
Published: February 2018

El presente artículo se propone una revisión de los conceptos que habitualmente se utilizan para la adscripción contextual de una obra poética. En este caso, se estudia la pertinencia de ubicar a Eduardo Milán (Rivera, Uruguay, 1952) dentro de los diferentes límites geográficos y políticos y la necesidad de buscar nuevas categorías que permitan dar cuenta de la alteración de los mismos. Análogamente, se hace indispensable repensar los elementos que determinan su situación dentro del panorama literario.
Los grados de la intertextualidad en "Los sinsabores del verdadero policía" de Roberto Bolaño: algunos planteamientos en torno a la ficción y el silencio literario
Authors: Gutiérrez Hibler Jonathan
Published: February 2018

La obra de Roberto Bolaño es sin duda un pretexto para conciliar la intertextualidad con la teoría de los mundos posibles debido a la ruptura taxonómica en los grados de la primera. A pesar de tratarse de una obra póstuma, Los sinsabores del verdadero policía no resulta ser una obra inacabada, en realidad ésta comienza una vez que el lector se desplaza a otros textos del autor y ahí es posible resaltar la riqueza de sus grados en la intertextualidad. Este comportamiento es típico del silencio narrativo, considerado como un juego de huellas en la orientación del texto: no sólo encontramos al narrador o los narradores como los ejes principales de la selección y filiación de la información narrativa, también la apropiación de otros textos es lo que crea una expansión textual en todos los géneros, específicamente en el narrativo. El objetivo de este trabajo consiste en plantear algunas interrogantes a la luz de momentos específicos de esta novela, principalmente los de notoria presencia intratextual, como es el caso del poema de Rimbaud leído por Amalfitano.

Adoption of Human Resources Management Policies for Practices: Harvard Model versus Religious Model
Authors: Babalola Oginni , Patience Erigbe , Afolabi Ojo , ‘Sola Laosebikan, , ‘Femi Ogunlusi,
Published: February 2018

The paper set out to explore two different models of Human Resources Management as a policy for practice that will be adequate for adoption by any organisation. The Harvard and Religious models were the two models critically examined vis – a – vis their implications on the practice of Human Resources Management (HRM). It was revealed that Harvard model of HRM is a content model as it is contingent on specific core issues (work system, reward system, employees’ influence and flow of people) in human resources management while Religious model of HRM is a process model as it is based on identification of relationship among components units (management and employees) Harvard model of HRM as a policy is embedded in the organisation through congruence, commitment, cost effectiveness and competence and Religious model of HRM is anchored on value based ideology through morality, honesty, sincerity, fairness and integrity. The two models are practicable but Harvard model of HRM has no exception to a particular party in business organisation while Religious model of HRM is averse to development of trade union in organisation. Therefore, the adoption of the two models will make world of work conducive, however, Harvard model of HRM aligned more with the nature and belief of business. However, combination of the two models to give a contingency – hybrid model will make the workplace to be better than adopting one of the models.

Suicide rates in the European Union Countries. An analysis from a multivariate approach
Authors: Gutiérrez-Barroso Josué , Barragán-Medero Fernando , Pérez-Jorge David
Published: February 2018

Suicide is one of the most important causes of death in the European Union Countries (EU) and is considered as a phenomenon which can be explained from a psychological, biological and social point of view. Objectives: This research will analyze the phenomenon of suicide in the European Union from a sociological point of view, with the aim of creating a multivariate model which explains such phenomenon. Method: Taking into account those data offered by the European Statistics Office (EUROSTAT), this study will try to explain, through the multiple linear regression model, suicide rates in European countries from demographic variables (number of inhabitants, divorce rate, ratio of women), economic variables (Gross Domestic Product (GDP), general government gross debt), social variables (government expenditure on social protection, population at risk of poverty) or educational variables (public expenditure on education and population with secondary education). Conclusions: A model to explain suicide rates in different countries was developed. This model was made up of two variables (percentage of people with secondary education and ratio of women), which account for 50% of the suicide rate.

Influence of Tourism Frequency on Association Model of Ecotourism Action
Authors: Wu Shwu-Ing , Hsu Hao-Ping
Published: February 2018

In recent years, many tour operators have entered to the ecotourism market aiming at the trend of ecotourism. In combination of local ecological and environmental resources, these tour operators have promoted a series of themed ecotourism paths and activities to attract tourists from different places. This study conducted literature review and empirical research to explore the influences of consumers’ tourism involvement, tourism values, perception of ecotourism and affection toward ecotourism on attitude toward ecotourism, perceived value of ecotourism, willingness of consumers and actual ecotourism action. Furthermore, association models were established, and the differences on the association models of tourist groups with different tourism frequencies were compared. Convenience sampling was used to survey the consumers who had participated in ecotourism. A total of 787 valid samples were collected. Based on tourism frequency, the respondents were divided into three groups, namely high frequency, medium frequency and low frequency, and the group models were compared. The results showed that (1) the influence of affection toward ecotourism on perceived value of ecotourism is the most significant among the four independent variables in the three tourism groups; (2) for all three tourism groups, tourism involvement has significantly negative influences on the paths of attitude toward ecotourism, and the influence of high-frequency tourism group is the highest; (3) tourism values of the high-frequency tourism group have a significantly negative influence on the path of perceived value of ecotourism while medium-frequency and low-frequency tourism groups have no significant influence; (4) in the medium-frequency tourism group, the affection toward ecotourism has a significantly positive influence on the path of attitude toward ecotourism, and the influence of this group is the highest while high-frequency and low-frequency groups have no significant influence; (5) for all three tourism groups, perceived value of ecotourism has a significantly positive influence on the path of attitude toward ecotourism and the influence of high-frequency tourism group is the highest.
On Estimating Non-standard Discrete Distributions Using Adaptive MCMC Methods
Authors: Baffoun Hatem , Hajlaoui Mekki , Farhat Abdeljelil
Published: February 2018

In this paper, we compare empirically the performance of some adaptive MCMC methods, that is, Adaptive Metropolis (AM) algorithm, Single Component Adaptive Metropolis (SCAM) algorithm and Delayed Rejection Adaptive Metropolis (DRAM) algorithm. The context is the simulation of non-standard discrete distributions. The performance criterion used is the precision of the frequency estimator. An application to a Bayesian hypothesis testing problem shows the superiority of the DRAM algorithm over the other considered sampling schemes.
Entrepreneurial Self-efficacy and Intention: Saudi Perspective
Authors: Alessa Adlah A.
Published: February 2018

The objective of this study has been to compare motivation, intention, fear of failure and self-efficacy in starting business ventures in Saudi Arabia. Inductive content analysis is used to identify the similarities and differences between two cites and groups of people in Saudi Arabia; both male and female entrepreneurs and those who have already established a business. Furthermore, the paper draws on data gathered from eight interviews in the cities of Riyadh and Jeddah. Four of these interviews were conducted with male entrepreneurs and the remaining four were with female entrepreneurs. A description and analysis of each entrepreneur was developed individually including short observations on the interviewees; noting movements and body language. We found the motivation for being one’s own boss is greater in Riyadh than in Jeddah (p=0.024) whereas self-efficacy is greater in Jeddah yet this difference is not significant. Regarding intention, no significant difference was found between region and gender. Finally, both regions consider fear of failure to be predictable. The study presents important contributions to theorists and practitioners in entrepreneurial activities in Saudi Arabia. Our research has contributed to the study in entrepreneurial motivation, intention, role of management, and role of culture of male and female entrepreneurs in Saudi Arabia hence providing more knowledge and information towards the behavior of Saudi entrepreneurs.
Social Network Site Usage by Small- and Medium-Sized Businesses: Understanding the Motivations and Barriers
Authors: Alshamaila Yazn
Published: February 2018

This paper contributes to a growing body of research on the process by which small- and medium-sized businesses (SMBs) adopt social network sites (SNSs) as part of their business strategies. If SMBs make use of SNSs, they could potentially compete with big corporations, flattening the marketplace. Open-ended online survey questions were used to collect data from 24 different social media experts in the Hashemite Kingdom of Jordan. Jordan was selected for this study because 90% of its adult Internet users are active on SNSs, a percentage that surpasses many emerging and developed countries. This research project identifies (a) relative advantage, (b) community demand, and (c) interactivity as motivating factors for SNS adoption. The survey results also reveal that (a) top management belief, (b) firm readiness, (c) negative comments and reviews, and (d) a low level of awareness are barriers to SNS adoption by SMBs in Jordan. The present study should prove to be particularly valuable to academics and business managers to formulate their business strategies regarding SNS adoption, and to pave the way for more research to assess likely changes.

An Apartment as a National Issue: On the Exhibitions of the Polish Applied Art Society at the Zachęta Gallery in 1902 and 1908
Authors: Adamska Katarzyna
Published: February 2018

Towarzystwo Polska Sztuka Stosowana (TPSS) organised two exhibitions at the Zachęta
Gallery. Their aim was to shape the national culture of living and to propagate ornamental
design inspired by indigenous motifs. The 1902 exposition was arranged in accordance
with the traditional perception of arts and crafts, which disregarded their function and
construction in favour of the external form. New critical categories, borrowed from the
language of functionalism and from ideas regarding living space as developed by the German
Kunstgewerbe circles, induced the members of the TPSS to arrange their 1908 exhibition
differently – as fully designed interiors rather than groups of independent items.
Similar changes were then observed in the of shop-window design and in commercial
expositions. The fact that they were explicated in terms of ethics reveals a combination
of consumerism, aesthetics and morality characteristic of the early 20th century.
Käthe Kollwitz and Otto Nagel: Two Exhibitions of “Progressive Artists” at the Zachęta in the Framework of Cultural Cooperation with the German Democratic Republic
Authors: Welbel Stanisław
Published: February 2018

The essay focuses on a discussion of two exhibitions hosted at the Zachęta Central Bureau
of Art Exhibitions in Warsaw that were organised in collaboration with the Committee
for Cultural Cooperation with Foreign Countries. This Committee, which existed in the
years 1950–1956, was an offi cial agency responsible for Poland’s cultural relations with
foreign countries. Its programme refl ected the state policy and focused on cooperation with
countries of the Eastern bloc. The events discussed in the essay were organised as part of
the cooperation with the German Democratic Republic; they were solo exhibitions of the
work of two German artists, Käthe Kollwitz in 1951 and Otto Nagel in 1955. They were
linked by the person of the painter Otto Nagel, who, being the guardian of Kollwitz’s
legacy, acted as the commissioner of her posthumous exhibition. The essay contains a critical
analysis of the texts published in the catalogues and of other printed matter associated
with the exhibitions as well as an analysis of related press reviews.
Meetings: Exhibitions of Women’s Art Curated by Izabella Gustowska
Authors: Jakubowska Agata
Published: February 2018

In February of 1978 the exhibition Trzy kobiety. Ania Bednarczuk, Iza Gustowska, Krynia
Piotrowska opened at the Bureau of Art Exhibitions in Poznań. It became a starting point
for two cycles of exhibitions that have been organised practically until today: Odbicia
(Gustowska’s and Piotrowska’s joint exhibitions) and Spotkania. The essay focuses on
Spotkania, i.e. exhibitions at which Gustowska (initially with Piotrowska) presented the
works of invited women artists. These exhibitions were Trzy kobiety (1978, Poznań), Sztuka
kobiet (1980, Poznań), Spotkania – Obecność I (1987, Poznań), Spotkania – Obecność III (1992,
Poznań), Presence IV – 6 Women (1994, Galeria La Coupole, Rennes) and Osiem dni tygodnia
(2011, Szczecin). To consider them a cycle and to analyse them under the joint title of
Spotkania is the author’s own interpretative approach based on the observation that, in
their case, Izabella Gustowska’s actions comprise a consistent project based mainly on the
recurrent gesture of creating an opportunity for women artists to meet – hence the word
meetings – and to engage in a dialogue.
Spotkania is the longest-lasting and most consistently carried out project enabling women
artists to meet but, paradoxically, not intended to consolidate them. All of the exhibitions
emphasised Gustowska’s certainty of essential closeness between women. This closeness
was always characterised, very generally and indistinctly, as a kinship that becomes evident
only when sought. An analysis of the exhibitions leads one to the conclusion that the
combination of the conviction that women share essential similarities with an emphasis
on their individuality and on the separateness of their artistic proposals, coupled with
Gustowska’s distancing herself from feminism, are the reasons why Spotkania did not
result in the emergence of any kind of community or in the undertaking of collective
actions. The exhibitions remained as incidental meetings and their infl uence on the oeuvres
of the women artists who participated in them is yet to be analysed.

“It’s their way of protecting them”: Between care and control in an honor context for youths with intellectual disabilities
Authors: Löfgren-Mårtenson Lotta , Ouis Pernilla
Published: February 2018

Today’s multicultural society is characterized by contradictory sexual norms that may have consequences for youths with intellectual disabilities’ possibilities of choosing a partner and expressing their sexuality. However, the body of knowledge concerning the area of youths with intellectual disabilities is limited. This study aims to examine professionals’ views on honor-related experiences among youths with intellectual disabilities. The data consists of nine qualitative interviews with professionals in special schools (personal assistants and teachers). In addition, 11 professionals were included at pre-meetings while designing the study. A thematic analysis was conducted while using sexual script as a theoretical framework. The results are presented in the following themes: (1) The professionals’ perceptions of the young people’s abilities to deal with honor-related experiences; (2) The professionals’ opinions of the existence of honor-related experiences among youth with intellectual disabilities; and (3) Descriptions of the professionals’ conduct toward the youths with intellectual disabilities concerning honor-related experiences. The analysis shows an honor script geared towards youths with intellectual disabilities, which can be described as a continuum between care and control connected to cultural sexual norms and to the disability. The families’ strive for a so-called normality seem to be an important factor in understanding for example arranged marriages among youths with ID. To meet the needs of these youths, the professionals require tools to navigate between care and control in this complicated arena of contradictory sexual and cultural norms.
In Defense of the Human Difference
Authors: McGrath Sean J. ,   International Association for Environmental Philosophy
Published: February 2018

Against the prevalent trend in eco-criticism which is to deny the human difference, I summon a set of untimely tropes from metaphysics in the interest of advancing an ecological humanism: the difference in kind between human consciousness and animal sensibility; the uniquely human capacity for moral discernment; and the human being’s peculiar freedom from the material conditions of existence. While I agree with eco-critics who argue that anthropocenic nature is not only finite, but sick: sickened by our abuse and neglect, I disagree that this abuse is simply a result of insisting on the human difference (“anthropocentrism”), nor is species egalitarianism the way forward. On the contrary, the eco-collapse, referred to as the sixth great extinction event, is the consequence of a general disavowal of the human’s special call to take responsibility for the relation between the human and the non-human, and only a re-awakening of this responsibility can restore health to anthropocenic nature. The non-human cannot effect this restoration, for that is not its vocation. A difference in vocation is not necessarily a difference in moral worth, and so the human difference does not justify denying the “intrinsic value” of the non-human. Humanity is uniquely responsible both for the mess we are in and for cleaning it up.
PURIFICATION OF 1-BUTYL-3-METHYLIMIDAZOLIUM CHLORIDE AFTER DISSOLUTION OF WHEAT STRAW
Authors: Evstaf’ev Sergei N. , Hoang Cuong Q
Published: February 2018

The existing technologies for the extraction of polysaccharides and lignin from lignocellulosic materials from an ecological and economic point of view are imperfect. The solution of this actual problem at present day is possible by heat treatment of lignocellulosic materials at the atmospheric pressure and relatively low temperature in the environment of ionic liquids. The use of ionic liquids for the fractionation of lignocellulosic raw materials isn't found industrial application because of their relatively high cost and sensitivity to contamination, despite the unique set of physico-chemical properties for dissolving cellulose. The solution of the problem is possible by reusing ionic liquid in the technological process without losing their effectiveness, which requires purification from impurities. The purpose of thе work was the comparative research of the efficiency of purification of 1-butyl-3-methylimidazolium chloride by adsorption on activated carbon, liquid extraction by organic solvents (benzene, dioxane, tetrahydrofuran) and supercritical CO2 extraction. It has been established that the methods of liquid extraction, supercritical CO2 extraction and adsorption on activated carbon can be used to purify 1-butyl-3-methylimidazolium chloride from extractives of wheat straw. For the purpose of comparison of efficiency of purification with above-mentioned methods the GC-MS, IR- and 1H NMR spectroscopy were used. It was revealed that extraction of impurities by organic solvents, such as benzene, dioxane and tetrahydrofuran, allows to reduce significantly their content in ionic liquid while supercritical CO2-extraction and adsorption on activated carbon almost completely remove impurities. Considering the substantial losses of the ionic liquid when using adsorption to purify 1-butyl-3-methylimidazolium chloride from the extractives of wheat straw, a supercritical CO2 extraction method can be recommended for use.Forcitation:Evstaf’ev S.N., Hoang C.Q.

Zincate-manganites with the composition NdM2IIZnMnO6 (MII− Mg, Ca) were synthesized using ceramic technology from oxides of Nd (III), Zn (II), Mn (III) and carbonates of alkaline-earth metals - magnesium and calcium. X-ray patterns of the prepared substancies were measured on a DRON-2.0 diffractometer. We established that they crystallize in the cubic system with the following unit cell parameters: NdMg2ZnMnO6 – а=13.927±0.035 Å, Z = 4, V0 = 2701.36±0.11 Å3, V0el.cell. = 675.34±0.03 Å3, ρX-ray = 4.20, ρpycn. = 4.19±0.01 g/cm3; NdCa2ZnMnO6 – а=13.910±0.030 Å, Z = 4, V0 = 2691.45±0.10 Å3, V0el.cell. = 672.86±0.03 Å3, ρX-ray = 4.04, ρpycn. = 4.01±0.08 g/сm3. The temperature dependence of the heat capacity of NdMg2ZnMnO6 and NdCa2ZnMnO6 was studied by dynamic calorimetry in the range of 298.15-673 K on the IT-S-400 calorimeter. Five parallel experiments were performed at each temperature point with 25 K step. The results were averaged and analyzed using mathematical statistics. As a result of calorimetric studies of the heat capacity, within the temperature range of 298.15-673 K, we discovered on the curves of the temperature dependence of heat capacity the phase transitions of the II kind at the following temperatures: 373, 548 К- NdMg2ZnMnO6, 448, 573 К – NdCa2ZnMnO6. These phase transitions were probably due to Schottky effects -the transition from semiconductivity to metallic conductivity, and variations in capacity, dielectric permittivity, the occurrence of Curie or Neel points. The equations of the temperature dependence of the heat capacity were derived on the basis of the experimental values with account the temperatures of the phase transitions. By the ion increment method, we calculated the standard entropies of the compounds investigated. We calculated the temperature dependences of С°р(Т) and thermodynamic functions Н°(Т)-Н°(298.15), S°(T) and Фхх(Т).Forcitation:Kasenov B.K., Kasenova Sh.B., Sagintaeva Zh.I., Kuanyshbekov Е.Е., Turtubaeva М.О.

Published: February 2018

Researches of polymer immobilized nanoparticles of ruthenium have been carried out by frontal polymerization (FP) of ruthenium acrylonitrile (AN) complex in the presence of inorganic carrier. Assessment of their catalytic properties in the hydrogenation reaction of unsaturated compounds has been done. Effective and selective organo-inorganic catalyst has been synthesized on the basis of akrylonitril complex and its reactivity in the hydrogenation reaction of cyclohexen has been investigated. Synthesis of akrylonitril complex of ruthenium on the surface of mineral carrier SiO2 silica, its further polymerization and reduction leads to the formation of polymer-inorganic composite including nano-size particle of Ru stabilized by polymer matrix and inorganic carrier. The offered method is a new approach in the catalyst preparing. Synthesized samples of Ru- nano composetes have been studied by methods of element analysis, IR-spectroscopy and X-ray analysis. There are wide diffraction peaks at 300-800 °C range in the X-rays patterns of the obtained samples wich correspond to crystallic ruthenium. Broadening diffraction maximums testifies ultradisperse state of particles. Microporous structure with pore sizes to 20 nm and their uniform size distribution are typical for obtained nano composites. It has been determined that specific surface of carriers decreases after polymerization of RuAN on the surface, though it is bigger than S spec. of the polymerization product in SiO2 absence. Obtained hybride nano composites have developed surface and porous structure which provide accessibility of active centers of catalyst for reagents and their high activity in the researched catalytic reaction. Formation conditions of Ru nanoparticles influence on catalytic properties of the studied composites, for example, the use of various regimes of frontal polymerization in inert medium. With the increase of the reduction treatment temperature of nano-composites the hydrogenation rate of cyclohexene reduces, the reason of which is the integration of Ru particles in the obtaining of nano composites at high temperatures. It should be mentioned that after hydrogenation the main ruthenium mass in poly-RuAN (90%) will have zero valency. The polymer matrix reduces. It is also subjected to changes and it confirms by spectrum broadening. Thus, the synthesized hybridization of polymer-immobilized Ru-nanoparticles display high activity in the reaction of cyclohexene hydrogenation and keep their activity during repeated cycles of reactions. Catalytic properties of nano-composites depend on the conditions of their obtaining which influence apparently on the size of forming Ruthenium nanoparticles.Forcitation:Agaguseynova M.M., Mikailova M.R.

Surface modification of titanium alloy VT 6 in aqueous solution containing 5 wt% of ammonium hydrate and 10 wt% of ammonium chloride in a temperature range of 650- 900 ºC by plasma electrolitic treatment was carried out. Characterization of surface layers of the alloy after plasma electrolytic treatment was done by Fourier Transform Infrared spectroscopy (FTIR) and powder X-ray diffraction (XRD). The FTIR spectra were recorded on a spectrometer BrukerVertex80 at room temperature in the range of 7500-350 cm-1. The spectra show the presence of rutile phase on the alloy surface after the plasma electrolytic treatment in the electrolyte solution of the indicated composition. The intensive bands at 654-643 cm-1, the weak bands near 560 cm-1 and the bands at 425-416 cm-1 can be assigned to rutile. The bands at 466-462 cm-1 are related to Ti-O-Ti stretching vibrations. With increasing temperature the relative intensity of the bands assigned to rutile increase. The plasma electrolytic treatment leads to appearence of the bands testifying enrichment of the alloy surface by nitrogen: the bands at 1634-1622 см-1 can be assigned to asymmetric bending of NH4+; the bands about 1539 cm-1 are related to N-H bending or symmetric bending of NH4+. The bands about 1428-1426 cm-1 can be also assigned to NH4+ bending vibrations. The plasma electrolytic treatment in the temperature range of 650-750 ºС results in appearance of the bands at 1069-1064 см-1. According to literature data, the bands can be assigned to vibrations of Ti-O-N. X-ray diffraction analysis allowed to ascertain crystal structure, phase identiﬁcation of the titanium alloy VT 6 after its plasma electrolytic treatment. The measurements were performed using a Bruker D8 Advance diffractometer with Mo Kα radiation (λ=0.07107 nm). Analysis of XRD patterns showed that titanium oxide in the samples is present as hongquiite phase (γ- monoclinic singony) and magnesium phase (hexagonal singony). Besides the peaks of TiO, the peaks which are characteristic for hamrabevit TiC in halite phase (cubic syngony) and Ti2O3 in corundum phase (trigonal syngony) were observed.Forcitation:Parfenyuk V.I., Tesakova M.V., Lutovac M., Kusmanov S.A., Lutovac B., Belkin P.N., Parfenyuk E.V.

Apprendre le sens de nouveaux mots dans un environnement riche en information. Une étude micro-développementale
Authors: Landry Danika , Dion Eric , Dupéré Véronique , Barrette Anne
Published: February 2018

Notre objectif était de déterminer la quantité d’aide dont les enfants ont besoin pour intégrer un nouveau mot à leur vocabulaire oral. Six séances ont été consacrées à l’enseignement de 24 mots à des élèves de maternelle de milieu défavorisé. Les mots ont été présentés à plusieurs reprises à l’aide d’une brève définition ainsi que d’une illustration. Les résultats indiquent que les enfants n’ont appris qu’un mot sur trois et que lorsqu’un mot était appris, c’était en moyenne après 2.4 séances. Nos résultats suggèrent qu’apprendre le sens d’un mot représente un apprentissage abstrait et par conséquent difficile pour les enfants.
