Chalcogen–Chalcogen Interactions in Furan-YHX and Thiophene-YHX Complexes (X = F, Cl, Br; Y = S, Se): An Ab Initio Study
Authors: Esrafili Mehdi D , Saeidi Nasibeh , Baneshi Mohammad Mehdi
Published: September 2015

In this work, ab initio calculations are performed to study chalcogen–chalcogen interactions in binary furan-YHX and thiophene-YHX (X = F, Cl, Br; Y = S, Se) complexes. Interaction energies of these complexes vary between −13.65 and −23.96 kJ mol−1 at MP2/aug-cc-pVTZ level. For a given X, complexes of SeHX have shorter chalcogen–chalcogen distances than SHX counterparts. The strength of the furan-YHX and thiophene-YHX complexes for a given Y decreases as follows: X = F > Cl > Br. Even though chalcogen–chalcogen interactions are mainly dominated by electrostatic effects, interaction energy decomposition analysis shows that polarization and dispersion effects also make important contributions to the stability of these complexes. In addition, charge-transfer from the O(S) lone pair to the σ*Y–X orbital leads to stabilization of these complexes. To further characterize the nature of chalcogen–chalcogen interactions, molecular electrostatic potential and quantum theory of atoms in molecules analyses are performed. Cooperative effects are observed when hydrogen bond and chalcogen–chalcogen interactions coexist in furan-YHF-HCN and thiophene-YHF-HCN.
Stitching across time: Heritage and history in contemporary Hong Kong fashion
Authors: Radclyffe-Thomas Natascha
Published: September 2015

Popular media celebrates the iconic Hong Kong dress – the cheongsam; yet, its existence is threatened as Hong Kong’s population of master tailors is rapidly dwindling. Hong Kong’s fashion identity is closely intertwined with the changing patterns of the global fashion industry. Hong Kong once buzzed with factories supplying the world’s wardrobes, but recent developments resulted in the loss of its manufacturing base, and as fashions changed the once ubiquitous cheongsam was consigned to fashion history. With the recent focus on heritage and slow fashion, making has become a key component in fashion marketing. Companies in the United Kingdom and United States are reviving old brands and launching new ones, using abandoned industrial equipment and reinvigorating local economies. This increased focus on country of origin, artisanship and sustainability also offers opportunities for Hong Kong to reposition itself, and this article surveys the contemporary fashion landscape in order to inform a debate on cultural heritage in fashion and its marketing.
Two different tales of fashion media industry development in Mainland China and Hong Kong
Authors: Tse Tommy
Published: September 2015

By revisiting relevant literature and case studies, this article first outlines Euro-American fashion media’s influence on and the development of the Chinese fashion media industry. The participant field research created chances for interviews with sixteen Chinese fashion media insiders from 2011 to 2013. Apparently, Hong Kong journalists take a pessimistic view of the local fashion industry. Mainland fashion media personnel, by contrast, take an optimistic view of the industry’s potential in China. The interview data suggest that such contradictory visions may arise from differing political changes and cultural biases. It is argued that the fashion media industry has never reached a cultural renaissance in either Hong Kong or China proper, despite their respective economic boom over the past decades. Fashion was taboo, a sign of bourgeois taste, and considered morally inferior in the communist ideology. Against this backdrop, colonial Hong Kong, where fashion was adopted to manifest a modern Chinese identity, did not share this ideological change. With the arrival of 1997, the situation changed under the fast-growing Chinese economy and information flow. The shifting fashion industries and cultural politics in the two regions construct new relations between the post-socialist country and its postcolonial city.
Born global: A new perspective for Chinese fashion design
Authors: Lindgren Tim
Published: September 2015

In this article I contend that the gathering momentum of the Chinese fashion industry has reached an important tipping point. Typically this impetus has been constrained by two key forces that have shaped the perception of Chinese development. Chinese culture and Chinese politics have long held an almost insurmountable presence over many aspects of daily life, including cultural and creative expression; however, this is changing rapidly, in part because of China’s global ascendency as an economically powerful nation, but more importantly because of borderless exchanges of aesthetic information due to globalization and the integration of digital and social media in daily life. This new perspective means that Chinese fashion designers must increasingly be born global, with a focus on creating innovative and agile business models as well as distinct aesthetic design signatures that resonate no longer with a country-specific consciousness but invoke a sophisticated world-view.
The fashioned victims: Addressing the un/dressed body in Hwang’s M. Butterfly
Authors: Lin Emile Cheng-Hsien
Published: September 2015

In The Body and Society, Turner indicates that ‘There is an obvious and prominent fact about human beings; they have bodies and they are bodies’. Human bodies are simultaneously dressed bodies. In M. Butterfly, Song’s dressed body lures/ seduces Gallimard into his calculated scheme, whereas his undressed body triggers the collapse of Gallimard’s fantasy and foregrounds the undermining subversion. Thus, Song’s un/dressed body plays a vital role and deserves further investigation. By addressing the un/dressed body it not only delves into the mechanism of deconstruction but also focalizes the inextricable connection between body and self-identity. The focus on the dressed and undressed body can exemplify how the representation of self through fashion can be carefully calculated to make and then break a person. Thus, this article seeks to address the un/dressed body to redress the core issues, such as power relation, sexuality and sexual orientation, dramatized in Hwang’s M. Butterfly in order to show the seminal relation between the body and shaping of identity. Moreover, it goes beyond to re-examine and challenge the dress/ body/self as a totality by arguing how both Song and Gallimard become fashioned victims through the experience of the sublime in the economy established by the bodily scheme.

Assessing chipper productivity and operator effects in forest biomass operations
Authors: Mola-Yudego Blas , Picchi Gianni , Röser Dominik , Spinelli Raffaele
Published: September 2015

The present research focuses on the productivity of energy wood chipping operations at several sites in Italy. The aim was to assess the productivity and specifically the effect attributed to the operator in the chipping of wood biomass. The research included 172 trials involving 67 operators across the country that were analysed using a mixed model approach, in order to assess productivity, and to isolate the operator effect from other potential variables. The model was constructed using different predictors aiming to explain the variability due to the machines and the raw-materials. The final model included the average piece weight of raw material chipped as well as the power of the machine. The coefficients of determination (R) were 0.76 for the fixed part of the model, and 0.88 when the effects due to the operators were included. The operatorsâ performance compared to their peers was established, and it was compared to a subjective classification based on the operatorâs previous experience. The results of this study can help to the planning and logistics of raw material supply for bioenergy, as well as to a more effective training of future forest operators.2
Общая устойчивость сжатых составных стержней переменного сечения
Authors: Сеницкий Юрий Эдуардович , Senitskii Yurii Eduardovich , Ишутин Александр Сергеевич , Ishutin Alexander Sergeevich
Published: September 2015

На основе технической теории стержней, кинематика деформирования которых дополнена деформациями поперечного сдвига, приводится точное решение задачи о потере устойчивости центрально сжатого составного стержня переменного сечения. Рассмотрен практически важный случай, соответствующий степенному закону изменения жесткости. В отличие от известных исследований, в работе используется прием, основанный на повышении порядка разрешающего дифференциального уравнения, что позволило в итоге получить новые результаты как для симметричных, так и для несимметричных форм потери устойчивости стержней при различных условиях их закрепления. Решения получены в цилиндрических, а для квадратичного закона изменения жесткости - в элементарных функциях. Показано, что учет деформаций поперечного сдвига решетки при оценке общей устойчивости составных стержней переменного сечения является обязательным.
Даламбертианы Леви и их применение в квантовой теории
Authors: Волков Борис Олегович , Volkov Boris Olegovich
Published: September 2015

Даламбертиан Леви - бесконечномерный дифференциальный оператор второго порядка, определенный по аналогии с лапласианом Леви.
У работы две цели: исследовать связи между различными определениями даламбертиана Леви и исследовать связь между даламбертианами Леви и уравнениями квантовой хромодинамики (уравнениями Янга-Миллса-Дирака).
Существуют два определения классического оператора Даламбера-Леви. Первое из них заключается в том, что этот оператор определяется как интегральный функционал, заданный специальным видом второй производной.
По-другому даламбертиан Леви можно определить с помощью средних Чезаро вторых производных по направлению вдоль векторов ортонормированного базиса.
В работе доказывается эквивалентность этих определений,
при этом используются слабо равномерно плотные ортонормированные базисы.
По аналогии с семейством неклассических лапласианов Леви в работе вводится семейство неклассических даламбертианов Леви, параметризованных линейными операторами на линейной оболочке базиса.
Показано, что связь даламбертиана Леви с калибровочными полями можно описать как с помощью классического даламбертиана Леви, который задается тождественным оператором на линейной оболочке базиса,
так и с помощью другого элемента семейства неклассических даламбертианов Леви.
В работе изучается связь между последним оператором и уравнениями Янга-Милсса с источником.
В частности, выводится система бесконечномерных уравнений, эквивалентная уравнениям квантовой хромодинамики и содержащая такой неклассический даламбертиан.
Представление вероятностей квантовых переходов функциональным интегралом в пространстве энергетических состояний
Authors: Бирюков Александр Александрович , Biryukov Alexander Alexandrovich , Шлеенков Марк Александрович , Shleenkov Mark Alexandrovich
Published: September 2015

В рамках формализма функционального интегрирования (интегрирования по траекториям) излагается непертурбативный метод описания динамики многоуровневых квантовых систем (атомов, молекул, наносистем), взаимодействующих с полем лазерного излучения высокой интенсивности. Вероятности переходов между состояниями квантовой системы под действием внешнего электромагнитного поля представляются функциональным интегралом в энергетическом представлении (в пространстве энергетических состояний исследуемой многоуровневой квантовой системы). На основании предложенного метода вычисляются вероятности переходов двухатомных молекул между энергетическими уровнями вращательных степеней свободы под действием серии пикосекундных импульсов лазерного излучения. Проведено численное моделирование динамики населенностей различных вращательных квантовых состояний молекул $^{14}\mathrm N_2$ и $^{15}\mathrm N_2$ под действием серии пикосекундых лазерных импульсов различной интенсивности и с различным периодом группы импульсов. Показано, что при определенных интервалах между лазерными импульсами наблюдается явление резонанса переноса населенности с низших на более высокие вращательные уровни исследуемых молекул. Данный резонанс исследуется при различных интенсивностях лазерных импульсов. Примечательно, что параметры лазерного излучения, при которых наблюдается резонансный переход населенностей молекул, различны для $^{14}\mathrm N_2$ и $^{15}\mathrm N_2$. Полученные результаты указывают на возможность селективного возбуждения изотопов под действием групп ультракоротких лазерных импульсов путем варьирования их интенсивности и периода следования в группе. Результаты численного моделирования количественно согласуются с результатами экспериментальных исследований [Phys. Rev. Lett., 2012, vol. 109, 043003].

В представляемой работе приводится построение полной системы независимых ротационно-инвариантных функциональных аргументов для лагранжиана нелинейного микрополярного (микроморфного) термоупругого континуума второго типа, который включает тензор конечной деформации Коши-Грина, температурное смещение, референциальный градиент температурного смещения, три вектора экстрадеформации и три несимметричных тензора экстрадеформации второго ранга. Дополнительные (экстра) реперы, связанные с микроэлементами, предполагаются нежесткими, что допускает наиболее общую аффинную экстрадеформацию микроэлементов континуума. Исходя из принципа наименьшего действия Гамильтона получены 4-ковариантные уравнения термоупругого поля в микрополярном континууме в канонической форме Эйлера-Лагранжа. Сформулированы дифференциальные и функциональные условия ротационной инвариантности плотности действия. Последние затем используются с целью поиска ротационно-инвариантных функциональных аргументов лагранжиана. Найдена система независимых ротационно-инвариантных функциональных аргументов лагранжиана. Дается формальное доказательство ее полноты. Построены удовлетворяющие принципу объективности формы определяющих уравнений гиперболического микрополярного термоупругого континуума, соответствующие ротационно-инвариантному лагранжиану.

Published: September 2015

O objetivo do estudo foi avaliar os níveis de matéria orgânica e do fósforo com suas frações num argissolo amarelo sob cultivo de culturas anuais submetidos a pousios. A vegetação regenerativa nos períodos de pousio foi submetida aos manejos de corte, trituração e deposição sobre o solo ou queimada. Considerou-se, desta forma, três tratamentos: Sistema de corte e queima da floresta secundária (MQ); Sistema de corte e trituração da floresta secundária (MT); Floresta secundária em 40 anos de pousio (FS). Das amostras de solo de cada uma dessas três áreas, analisou-se: matéria orgânica (MO), fósforo total (Pt), fósforo total lábil (Ptl), fósforo orgânico lábil (Pol), fósforo inorgânico lábil (Pil) e fósforo disponível (Pd). Os maiores valores de Pt foram encontrados na FS devido ao maior estado de equilíbrio edáfico encontrado neste tratamento. O solo sob manejo com deposição de resíduos vegetais (MT) apresentou os maiores valores de matéria orgânica e das frações total lábil (Ptl), orgânica lábil (Pol), inorgânica lábil (Pil) e disponível (Pd) em comparação com o manejo de queima da floresta (MQ) em regeneração, que, por sua vez, em comparação com o solo de uma floresta em pousio há quarenta anos apresentou menores valores dessas variáveis analisadas, exceto para Pt. O manejo com a conservação dos resíduos vegetais no sistema mostrou ser benéfico quanto ao incremento de matéria orgânica e aporte de frações de fósforo no solo, opostamente ao que apresentou o manejo com queima da vegetação em regeneração.

Published: September 2015

O objetivo deste trabalho foi avaliar a produção e a qualidade do tomate sob diferentes adensamentos e número de hastes. O estudo foi conduzido na fazenda Murici no município de Ibicoara – BA, em delineamento blocos casualizado com 8 repetições e esquema fatorial 2 x 2, com dois espaçamentos (1,4 x 0,5 e 1,4 x 0,25 m), duas quantidades de hastes por planta (uma e duas hastes). Ao final, foi avaliado o número de frutos por planta, diâmetro longitudinal, diâmetro transversal, peso médio dos frutos, produção por planta, produtividade, pH da polpa do fruto, teor de ácido ascórbico, acidez titulável, teor de sólidos solúveis, relação sólidos solúveis e acidez titulável e firmeza. O adensamento conferiu menores quantidades de fruto e peso médio por fruto, mas obteve maior produtividade. Enquanto o tomateiro produzido com duas hastes obteve maior número de frutos e menor peso médio por fruto, mas atingiu maior produtividade. Em relação a qualidade dos frutos melhores resultados foram alcançados utilizando plantio com menor adensamento e plantas conduzidas com uma haste. Para a produção de tomate, recomenda-se o plantio em maior adensamento, aliado à condução das plantas com duas hastes. Porém, acarretará na obtenção de frutos com menor calibre, mais leves e menor qualidade do fruto.

O presente trabalho apresenta a potencialidade no uso de imagens termais aéreas de alta resolução da superfície urbana como ferramenta para mapear zonas de conforto térmico. Utilizou-se uma câmera termal de alta resolução, modelo FLIR SC660, com resolução espacial de 1,5 m e espectral de 640x480 pixels, em sobrevoo na área urbana do município de Piracicaba, São Paulo, Brasil, durante o dia 30 de outubro de 2012, em três períodos: 08:36 (manhã), 14:27 (tarde) e 19:23 (noite), horário local. No Brasil, ainda são poucos os trabalhos realizados com imagens termais de alta resolução em levantamentos aéreos. Por meio de técnicas de sensoriamento remoto das imagens obtidas, foi possível identificar o campo térmico na área de estudo sob influência, principalmente, do asfalto, classe com temperatura de superfície mais alta (55,7 °C às 14:27), e vegetação e corpos d’água, as quais minimizaram o efeito.
Youth and intimate media cultures: Gender, sexuality, relationships, and desire as storytelling practices in social networking sites
Authors: de Ridder Sander , van Bauwel Sofie
Published: September 2015

This paper investigates how young people give meaning to gender, sexuality, relationships, and desire in the popular social networking site (SNS) Netlog. In arguing how SNSs are important spaces for intimate politics, the extent to which Netlog is a space that allows contestations of intimate stories and a voicing of difference is questioned. These intimate stories should be understood as self-representational media practices; young people make sense of their intimate stories in SNSs through media cultures. Media cultures reflect how audiences and SNS institutions make sense of intimacy. This paper concludes that intimate stories as media practices in the SNS Netlog are structured around creativity, anonymity, authenticity, performativity, bricolage and intertextuality. The intimate storytelling practices focusing on creativity, anonymity, bricolage and intertextuality are particularly significant for a diversity of intimacies to proliferate.
Carbon fiber-reinforced plastics based on epoxy resin toughened with core shell rubber impact modifiers
Authors: Park Hyeongcheol , Jung Hana , Yu Jaesang , Park Min , Kim Seong Yun
Published: September 2015

The weak impact properties of carbon fiber-reinforced plastics (CFRPs) are due to their laminated structure, thus limiting the use of these materials in various automotive applications even though they provide weight savings as compared with metal materials. In this study, core shell rubbers (CSRs), which are known for their excellent dispersion characteristics, were selected as an impact modifier and CFRPs incorporated with CSRs were fabricated using the vacuum-assisted resin transfer molding process to enhance their impact properties. CFRPs with highly reinforced carbon fibers of 72–74 wt.% were prepared without voids as confirmed by morphological and thermogravimetric data. The impact strength of the CFRPs was improved by up to 87.5%, depending on the increase in CSR content, but their tensile properties were not reduced, indicating that these properties were predominantly determined by the continuous reinforcement of carbon fibers. Therefore, CSRs are an effective impact modifier for improving the impact properties of CFRPs. These findings will help in increasing the use of CFRPs as automotive structural materials.

Carboxymethyl cellulose and hydrogel beads produced from sugar cane bagasse (SCB) and palm kernel cake (PKC) were characterised, and the ability of the hydrogel beads to encapsulate and protect the probiotic bacteria of Lactobacillus acidophilus (LA-5) under simulated gastrointestinal conditions was investigated. Encapsulation with SCB and PKC hydrogel beads was performed with 87.4% and 80.9% efficiency, respectively, compared with that with alginate hydrogel beads, which had 75.0% efficiency. LA-5 free cells and those encapsulated in alginate hydrogel beads showed no survival. LA-5 cells encapsulated in SCB and PKC hydrogel beads retained high survival under stomach conditions of pH 2 after 1.5 h (>6 log CFU/ml) and 3 h (>4 log CFU/ml). However, no survival of cells was observed under colon conditions of pH 7.5 after 24 h. SCB and PKC hydrogel beads were able to protect the cells against the pH conditions of the stomach but not of the colon.

Capacity of Cognitive Radio with Partial Channel Distribution Information in Rayleigh Fading Environments
Authors: Xu D. , Li Q.
Published: September 2015

This paper investigates the capacity of the secondary user (SU) in a cognitive radio (CR) network in Rayleigh fading environments. Different from existing works where perfect channel state information (CSI) or channel distribution information (CDI) of the interference link from the SU to the primary user (PU) is assumed to be available, this paper assumes that only partial CDI is available. Specifically, we assume the distribution parameter is unknown and estimated from a set of channel gain samples. With such partial CDI, closed-form expressions for the ergodic and outage capacities of the SU are obtained under the transmit power and the interference outage constraints. It is shown that the capacity with partial CDI is not degraded compared to that with perfect CDI if the interference outage constraint is loose. It is also shown that the capacity can be significantly improved by increasing the number of channel gain samples.

Military Expenditures and Free-Riding in NATO
Authors: Odehnal Jakub
Published: September 2015

Changes in the security environment after the Cold War and decreasing number of armed conflicts in NATO member states lead these countries to a gradual reduction in military expenditure. However, new security threats that these countries faced at the beginning of the 21st century brought a massive growth of military expenditure especially in the USA which lead to significant deepening of disparities between the USA and European NATO member states. The aim of the article is to investigate disproportionality of burden sharing among 28 NATO members and via multidimensional statistic methods identify free-riding in Alliances. A model based on theory of the demand for military spending provides the basis for an investigation of the disparities (identified especially in the characteristics of the economic and security environment) in determinants influencing military expenditure. Finding suggest that the Alliance is not mainly an economically homogenous body and individual economies thus allocate a significantly different amount of GDP for the needs of the armed forces in dependence on political priorities of individual governments, public finances or overall economic condition of national economies. However, the results of the classification model reveal the fact that group of countries identified as core states of the “traditional” NATO member states (with above-average values of variables) do not allocate the long-term recommended amount of military expenditure of 2% of GDP. These countries are suspected of dangerous free-riding.
N,N′-Bis(benzoyl) adipic acid dihydrazide and talc: nucleating agents for poly(l-lactic acid)
Authors: Xue Bai , Guo Dan , Bao Jianjun
Published: September 2015

In this paper, high-heat-resistant polymeric composite products were prepared via the traditional melt blending process by incorporating N,N′-bis(benzoyl) adipic acid dihydrazide (BAAD) into poly(l-lactic acid) (PLLA), which acted as an organic nucleating agent. The heat distortion temperature (HDT) of the PLLA/BAAD composite samples was measured by an HDT apparatus, and a high value of 96.2°C was achieved at a BAAD loading fraction of 0.5 wt.%, whereas, at the same processing conditions, the HDT of PLLA/talc specimens reached a similar value at a talc content of 20 wt.%, which was much higher than the BAAD content. Differential scanning calorimetry and X-ray diffraction analyses were applied to determine the melting and crystallization behavior of the PLLA/BAAD blends. Polarized optical microscopy was used to observe the crystalline morphologies. Thermogravimetric analysis was employed to study the effect of BAAD on the thermal stability of PLLA. Measurement of the mechanical property confirmed that the addition of BAAD was beneficial to the enhancement of the mechanical properties of the resulting blends. However, the tensile strength of the PLLA/talc composites decreased with increasing weight fraction of talc.
Valorization of industrial by-products through bioplastic production: defatted rice bran and kraft lignin utilization
Authors: Klanwan Yanut , Kunanopparat Thiranan , Menut Paul , Siriwattanayotin Suwit
Published: September 2015

The objective of this study was to develop a bioplastic from industrial by-products. Commercial defatted rice bran (DRB) was extruded with 0–30% kraft lignin (KL) as a filler and 30% glycerol as a plasticizer. Firstly, the effect of extrusion temperature on the plasticized DRB’s processability was determined. Increasing the die extrusion temperature from 100°C to 150°C improved the extrudability by decreasing the die pressure and motor current. Subsequently, the effect of KL on plasticized DRB was studied. The addition of 10–30% KL improved DRB processability. The addition of 30% KL markedly lowered the die pressure in comparison to using a 150°C extrusion temperature. Moreover, KL addition decreased DRB viscosity determined by a capillary rheometer. These results were coherent with a decreased storage modulus in a rubber state and an increased tan δ height determined by a dynamic mechanical thermal analyzer (DMA). However, n values of DRB with 10–30% KL could not be explained by a simple mixing rule. This may be attributed to the interaction between DRB and KL, as shown by Fourier transform infrared (FTIR) spectra. KL addition increased Young’s modulus and the glass transition temperature (T
g) of plasticized DRB. Therefore, blending DRB with KL is an effective way to improve polymer flowability at the processing temperature and mechanical properties at ambient temperature.
On “R” in phrasal compounds – a contextualist approach
Authors: Meibauer Jörg
Published: September 2015

In phrasal compounds of the type XP+Y, one can assume a relation “R” that holds between the head and the non-head just as in ordinary N+N compounds. The paper discusses the question how “R” should be understood. Three recent approaches, i.e., construction morphology, parallel architecture view, and indexicalism are discussed. It is argued that all approaches lack a pragmatic component which is necessary for modeling pragmatic inferencing with respect to phrasal compounds. Thus, an “unspecific meaning” approach to the semantics of phrasal compounds, together with contextualist views on pragmatic enrichment, is a serious alternative to the approaches discussed.

In this paper, we compare Modern Greek nominal compounds to their Turkish counterparts and reveal that Modern Greek nominal compounds under investigation are morphological while Turkish ones are syntactically built. Based on this, we offer an explanation for the availability of phrasal compounds in Turkish but not in Modern Greek: phrase-level items can be involved in syntactic compounds, but not in morphological compounds involving solely morphological items. The study reveals that the locus of compound formation is not confined to a single module both cross-linguistically and within a language, but the locus of a specific type of compound in a language entails whether or not phrasal compounds with the same compound structure can also occur in that specific language.
Phrasal compounds in Turkish: Distinguishing citations from quotations
Authors: Göksel Aslı
Published: September 2015

To date, studies of phrasal compounds, most of which are on Germanic languages, have been inconclusive with respect to whether the non-heads are phrases or quotations. In this paper, I present syntactic, semantic, and prosodic evidence from a typologically different language, Turkish, to distinguish between the two types. I will show that what look like equally complex constructions turn out to differ radically in complexity and in terms of their internal structure; phrases that are sensitive to syntax versus quotations which are not, and head-complement relations versus type-token relations. I further discuss the structural implications of having phrasal units within morphological units, arguing that this is a natural phenomenon within frameworks where the relation between morphology and syntax is bidirectional.
Do Romance languages have phrasal compounds? A look at Italian
Authors: Bisetto Antonietta
Published: September 2015

Phrasal compounds did not constitute a highly debated issue in Italian, apart from some sporadic observations (Ricca 2005) on peculiar compounds as, for example, V+N exocentric compounds likespazzaneve‘snowplough’ that admit NP constituents. This paper is devoted to the analysis of a group of N+NP constructions, found in the ItTenTen10 corpus, a corpus of 2.588.873.046 words investigated by means of the Sketch-Engine, with the purpose of establishing whether phrasal compounding is a phenomenon present in Italian too.

Background: The goal of the present study was to evaluate the color preferences of patients with schizophrenia
and their correlations with personality traits. Methodology: Sixty-three patients with schizophrenia and 59
healthy volunteers were asked to undertake the color preference and the Zuckerman-Kuhlman Personality
Questionnaire (ZKPQ) tests. Results: The healthy volunteers showed a greater preference for green but a lesser one
for brown compared to the patients with schizophrenia. Patients scored higher than the healthy volunteers on
the ZKPQ Neuroticism-Anxiety and Activity scales. Moreover, in patients, black preference ranking was associated
with the Neuroticism-Anxiety, whereas pink and orange preferences were negatively associated with Activity;
white preference correlated negatively with Sociability. Conclusions: Patients with schizophrenia preferred green
less but brown more, and displayed their personality correlates of these color preferences. These findings are
suggesting that patients with schizophrenia should be encouraged to be more exposed to bright colors such as
green and white, and less to dark colors such as black, during therapy and rehabilitation sessions.

Published: September 2015

Ternary palladium and platinum oxides NaPd3O4and NaPt3O4are studied theoretically using DFT. The calculated structural parameters and geometry are found consistent with the experiments. The mechanical properties analysis show that both compounds are elastically stable; anisotropic and reveal the ductile nature. Electronic cloud explain that the chemical bond between Na and Pd/Pt is ionic, whereas between O and Pd/Pt is covalent. The electronic band structures and densities of states demonstrate that these compounds are metals. The d-state splitting explains the origin of the electronic behaviour of these oxides. The optimised magnetic phase energies and magnetic susceptibility confirm that these oxides are paramagnetic metals.
2,5-Bridged 1-Carba-arachno-pentaborane(10) Derivatives – Intermediates on the Way to Pentaalkyl-1,5-dicarba-closo-pentaboranes(5)
Authors: Wrackmeyer Bernd , Schanz Hans-Joerg
Published: September 2015

Stimulated by a report from (R. Köster, G. Benedikt, M. A. Grassberger, Liebigs Ann. Chem. 1968, 719, 187.) on a carbaborane, for which the structure of 2,3,4,5,-tetraethlyl-1-methyl-2,5-μ-(ethyl-1′,1′-diyl)-1-carba-arachno-pentaborane(10) 1 was proposed, an independent synthesis was developed. Diethyl(ethynyl)borane was generated in situ in the presence of a large excess of “Et2B–H” (hydride bath) by ethynyl/H exchange, using ethynyl(trioctyl)tin to react in a mixture with diethyl(vinyl)borane at low temperature. Hydroboration and Et2B–H-catalysed condensation afforded 1, as shown by 11B, 13C NMR spectroscopy and DFT calculations. Thermal degradation of 1 gave 2,3,4-triethyl-1,5-dimethyl-1,5-dicarba-closo-pentaborane(5), whereas the pentaethyl-1,5-dicarba-closo-pentaborane(5) resulted from thermally induced decomposition of other suitably substituted arachno carbaboranes.

Reactive oxygen species in disease: Rebuttal of a conventional concept
Authors: Vitetta Luis , Coulson Samantha , Linnane Anthony W
Published: September 2015

The production of intracellular reactive oxygen species and reactive nitrogen species has long been proposed as leading to the random deleterious modification of macromolecules (i.e., nucleic acids, proteins) with an associated progressive development of the age associated systemic diseases (e.g., diabetes, Parkinson’s disease) as well as contributing to the ageing process.   Superoxide anion (hydrogen peroxide) and nitric oxide (peroxynitrite) comprise regulated intracellular second messenger pro-oxidant systems, with specific sub-cellular locales of production and are essential for the normal function of the metabolome and cellular electro-physiology.  We have posited that the formation of superoxide anion and its metabolic product hydrogen peroxide, and nitric oxide, do not conditionally lead to random damage of macromolecular species such as nucleic acids or proteins.  Under normal physiological conditions their production is intrinsically regulated that is very much consistent with their second messenger purpose of function.   We further propose that the concept of an orally administered small molecule antioxidant as a therapy to abrogate free radical activity (to control oxidative stress) is a chimera.  As such we consider that free radicals are not a major overwhelming player in the development of the chronic diseases or the ageing process.

Authors: Кашин И.А. , Kashyn I.A.
Published: September 2015

Virtual screening of chemical compounds able to mimic pharmacophoric properties of broadly neutralizing monoclonal antibody 10E8 against HIV-1 was carried out.
Evaluation of the efficacy of binding of these compounds to the membrane-proximal external region (MPER) of the HIV-1 gp41 protein critical for fusion of
the virus membrane with a target cell was performed by molecular docking and molecular dynamics simulations. Eight chemical compounds exhibiting negative
values of the free energy of binding to this functionally important site of HIV-1 were identified. The data obtained testify to the availability of these
molecules in the studies aimed at the design of novel antiviral drugs presenting the HIV-1 fusion inhibitors that block the MPER region of the gp41 protein.

Published: September 2015

In line with the goals of sustainable development and environmental
protection today great attention is directed towards new technologies for
waste and industrial by-products utilization. Waste products represent
potentially good raw material for production other valuable products, such as
bioethanol, biogas, biodiesel, organic acids, enzymes, microbial biomass,
etc. Since the first industrial production to the present, lactic acid has
found wide application in food, cosmetic, pharmaceutical and chemical
industries. In recent years, the demand for lactic acid has been increasing
considerably owing to its potential use as a monomer for the production of
poly-lactic acid (PLA) polymers which are biodegradable and biocompatible
with wide applications. Waste and industrial by-products such are whey,
molasses, stillage, waste starch and lignocellulosic materials are a good
source of fermentable sugars and many other substances of great importance
for the growth of microorganisms, such as proteins, minerals and vitamins.
Utilization of waste products for production of lactic acid could help to
reduce the total cost of lactic acid production and except the economic
viability of the process offers a solution of their disposal. Fermentation
process depends on chemical and physical nature of feedstocks and the lactic
acid producer. This review describes the characteristics, abilities and
limits of microorganisms involved in lactic acid production, as well as the
characteristics and types of waste products for lactic acid production. The
fermentation methods that have been recently reported to improve lactic acid
production are summarized and compared. In order to improve processes and
productivity, fed-batch fermentation, fermentation with immobilized cell
systems and mixed cultures and opportunities of open (non-sterilized)
fermentation have been investigated.
