Authors: Virdee J , Pafitanis G , Alamouti R , Brohi K , Patel H
Published: June 2018

Introduction

This study presents an extensive retrospective database of patients with polytrauma following train-related injuries and highlights the key lessons learnt in this rare clinical presentation.

Materials and methods

We retrospectively collected data from 127 patients who presented to Royal London Hospital after sustaining train related trauma. We analysed demographics, accident report data, aetiologies and clinical management interventions. All data were screened and injuries were mapped to various anatomical regions. The revised trauma score, injury severity score and new injury severity scores were used to quantify injury extent.

Results

Mean patient age was 41 years (range 16–81 years) with a 73% to 27% male to female ratio. Deliberate injuries occurred in 71% of patients, with accidental injury accounting for 29%. The mean new injury severity score was 26.48 (range 1–75), with the most common injuries sustained to the chest and the extremities. Pneumothorax, haemothorax or tension pneumothorax occurred in 44% of patients, with 11% suffering a flail chest injury. Traumatic amputations occurred in 33% of patients and 56% of patients required admission to intensive care. Total mortality rates were 19%, with 12% of patients dying at day 0 and 18% at day 7, respectively.

Conclusions

This study demonstrated the significant impact of train-related polytrauma and provided a comprehensive injury patterns. It was observed that deliberate polytrauma is related to psychiatric deliberate harm but there is no significant difference in the patterns of injuries between accidental and deliberately caused injuries. Overall injuries to the thorax and extremities were the most severe, demonstrating the highest mean injury scores.

Published: June 2018

No presente trabalho, foram estudadas as isotermas de adsorção do CO2 sobre carvão ativado produzido a partir de endocarpo de coco (Cocos nucifera L.) que constitui um resíduo gerado em diversos processos agroindustriais. O carvão sintetizado foi caracterizado por espectroscopia de infravermelho com transformada de Fourier (FTIR), fluorescência de raios X (FRX) e quantificação de grupos ácidos e básicos via método de Boehm. Na obtenção das isotermas de adsorção do CO2 foi utilizada a técnica volumétrica estática em uma coluna de leito fixo de 2 cm de diâmetro interno, 25 cm de altura e volume interno de 138,55 cm3, sob temperatura constante de 24 °C. Os resultados mostraram que a superfície do adsorvente apresentou grupos ácidos, fenólicos, lactonas e básicos. A isoterma de equilíbrio obtida seguiu o comportamento do tipo I da classificação da IUPAC. A capacidade máxima de adsorção de CO2 foi de 64,196 mg.g-1, sob pressão inicial de 3,4 bar e temperatura de 24°C.

Current evidence suggests that estradiol (E2), the main ovarian steroid, modulates energy balance by regulating both feeding and energy expenditure at the central level, through the energy sensor AMP-activated protein kinase (AMPK). We hypothesized that the hypothalamic mechanistic target of rapamycin (mTOR) pathway, a well-established nutrient sensor and modulator of appetite and puberty, could also mediate the anorectic effect of E2. Our data showed that ovariectomy (OVX) elicited a marked downregulation of the mTOR signaling in the arcuate nucleus of the hypothalamus (ARC), an effect that was reversed by either E2 replacement or central estrogen receptor alpha (ERα) agonism. The significance of this molecular signaling was given by the genetic inactivation of S6 kinase B1 (S6K1, a key downstream mTOR effector) in the ARC, which prevented the E2-induced hypophagia and weight loss. Overall, these data indicate that E2 induces hypophagia through modulation of mTOR pathway in the ARC.
Healthy Roots: Building capacity through shared stories rooted in Haudenosaunee knowledge to promote Indigenous foodways and well-being
Authors: Gordon Kelly , Lickers Xavier Adrianne , Tait Neufeld Hannah
Published: June 2018

Urban and reserve-based First Nation families in southern Ontario frequently experience food insecurity as well as more limited access to traditional, more nutrient dense foods from the local environment. Healthy Roots was initiated in the community of Six Nations to promote traditional food consumption. A small number of participants eating only locally available foods reported better-controlled blood glucose, positive weight change and increased traditional food knowledge. New relationships and partnerships were also developed. Our Sustenance, a community organization that was responsible for the local farmers market, community gardens, good food box program, and other community programs, joined the Healthy Roots Committee to continue advancing the knowledge and activation of the community-based initiatives such as the development of a Haudenosaunee Food Guide. Healthy Roots may serve as a model and inspiration to other Indigenous communities looking to reconnect to their local environments and Indigenous lifeways to promote Indigenous foodways and well-being.
Exploring homelessness and Indigenous food Systems in northern British Columbia
Authors: Russell Julia , Parkes Margot W.
Published: June 2018

People experiencing homelessness are known to be highly food insecure, but outside of emergency aid little is known about their overall experiences with food, particularly in Canada’s northern communities. This study examined experiences that influenced access to food for people experiencing homelessness in a small city in northern British Columbia. Early findings underscored the importance of the impacts of colonization when seeking to understand food access in this context, and the value of lived experiences (including people with experiences of homelessness) when seeking to understand Indigenous food systems and food sovereignty as part of a re-emerging food system. The research drew on ethnography and case study methodology with modified community mapping to explore the food systems of the participants, who identified as First Nations, Métis or had mixed Indigenous and European ancestry. A focus group and subsequent interviews revealed a dynamic and complex food system. The flexible research design enabled participants to creatively express the food-related issues, challenges and successes most pertinent to their lives. Key food-related themes were social connections, as well as connections to the land and to culture. Participants’ experiences, actions and desires regarding food, health and well-being highlighted Indigenous food sovereignty as an overarching concept which offers an adaptable, holistic approach that can accommodate complexity. It is a valuable direction for future research and practice seeking to improve food security and health.

Published: June 2018

Food insecurity among Indigenous Peoples of northern Canada is a significant public health issue that is exacerbated by changing social and environmental conditions. While a patchwork of programs, strategies and polices exist, the extent to which they address all “pillars” of food security (food availability, access, quality, and utilization) remains under-assessed. We respond to this gap by providing a framework for synthesizing and assessing information about food security initiatives, using a case study of the Inuvialuit Settlement Region (ISR), the westernmost Inuit region of Canada. Our objectives are: (1) to identify existing initiatives in the ISR; (2) to assess the breadth and diversity of these initiatives in addressing the four key food security “pillars”; and (3) to present an analytical framework that will facilitate ongoing data updating and sharing in the ISR and elsewhere. Through a scoping review and direct consultation with 12 key informants, we identified 30 initiatives that support food security in the ISR. These are funded and implemented at a range of national, territorial, regional, and local levels, and include both governmental and non-governmental programs, strategic frameworks, and research and monitoring initiatives. Seven key themes emerged from the cross-scale analysis of these initiatives, including: orientation with respect to food security pillars, scope and scale, demographic targeting, funding, monitoring and evaluation, and implications for food security strategies. While our framework provides a useful tool for data synthesis and analysis, its outputs can help in identifying gaps and opportunities for both resource allocation and program and policy development for under-served communities. Significantly, this study highlights the importance of engaging local perspectives in the development of coordinated approaches to address Inuit food insecurity.
Responsibilities and reflections: Indigenous food, culture, and relationships
Authors: Martens Tabitha Robin
Published: June 2018

Understanding Indigenous food systems requires positioning ourselves in our own understanding of Indigenous food, culture, and place. The resurgence of Indigenous culture occurring around food, and the protection and revitalization of Indigenous food systems must be documented with a commitment to Indigenous values, worldviews and perspectives. This commentary offers insight into how we can do so.

Gastroesophageal reflux (GER), generally defined as the passage of gastric contents into the esophagus, is an almost universal phenomenon in preterm infants. It is a common diagnosis in the NICU; however, there is large variation in its treatment across NICU sites. In this clinical report, the physiology, diagnosis, and symptomatology in preterm infants as well as currently used treatment strategies in the NICU are examined. Conservative measures to control reflux, such as left lateral body position, head elevation, and feeding regimen manipulation, have not been shown to reduce clinically assessed signs of GER in the preterm infant. In addition, preterm infants with clinically diagnosed GER are often treated with pharmacologic agents; however, a lack of evidence of efficacy together with emerging evidence of significant harm (particularly with gastric acid blockade) strongly suggest that these agents should be used sparingly, if at all, in preterm infants.

Abstract To describe the parasitic community of the Magellanic Horned Owl, Bubo magellanicus (Aves, Strigiformes), 19 carcasses from central Chile were analyzed. Ectoparasites were collected through plumage inspection, while endoparasites were collected through traditional techniques of parasitological necropsy. Sixteen owls were infected with at least one species of ectoparasite (84.21%) or endoparasite (31.58%). Eleven of 19 birds (57.89%) harbored feather mites of the three species Pandalura cirrata (42.11%), Glaucalges attenuatus (47.37%), and Kramerella sp. (10.53%), whereas 16 individuals (84.21%) harbored the chewing louse Strigiphilus chilensis. Only six birds (31.58%) were infected with helminths; the nematodes Capillaria tenuissima (26.32%) and Dispharynx nasuta (5.26%); the acanthocephalan Centrorhynchus spinosus (5.26%); and the trematode Neodiplostomum sp. (5.26%). Apart from S . chilensis, all parasites comprised new records for B . magellanicus.
Cost estimation of utility strikes: towards proactive management of street works
Authors: Makana Lewis O , Metje Nicole , Jefferson Ian , Sackey Margaret , Rogers Chris D F
Published: June 2018

The true (full) cost of a utility strike incident is rarely known. Generally, only the direct costs are used to measure the impact of utility strikes; the wider indirect and social costs are rarely quantified in monetary terms. Moreover, no established methodology exists to address this gap in knowledge, while access to fully documented records often presents the greatest challenge. This paper presents research that for the first time has been given access to 16 fully detailed utility strike case studies in UK urban areas. The research has identified and assessed the impacts of these utility strikes and provided an objective estimation of their associated (total) costs. These costs consist of those paid directly by the utility owner (direct costs), those borne by third parties in the contractual agreement (indirect costs) and those borne by other parties not engaged in the contractual agreement (social costs). Although the richness lies in the detailed case studies, the aggregated findings from all 16 utility strike case studies indicate that the total cost ratio – the ratio of indirect and social costs to the direct cost of repair – is 29:1. Thus there is a very substantial impact, which to date has been largely neglected.
Feasibility of long-term NDT programme for system-wide monitoring of bridge deck condition in Indiana, USA
Authors: Taylor Benjamin , Qiao Yu , Bowman Mark , Labi Samuel
Published: June 2018

Through effective and proactive monitoring, highway agencies can acquire information needed for deck repair or replacement timing decisions. However, system-wide monitoring of infrastructure requires a large expenditure outlay and therefore needs to be justified by comparing its costs to the potential savings if such monitoring leads to timely actions. This paper presents a framework that considers two strategies for managing a bridge deck network: a condition-based strategy that involves monitoring and repair and a time-based strategy that involves repairs at specific time intervals without condition monitoring. Using a case study, the paper calculates the life-cycle cost of each strategy as the sum of the monitoring and repair costs. The paper estimates that if a non-destructive test (NDT) is used as the monitoring platform system-wide, the unit monitoring cost will be $0·04–0·35/ft2 ($0·43–3·77/m2) of deck (average $0·22/ft2 ($2·37/m2)). This cost is expected to be different for other inventories due to differences in age, inventory size and bridge proximities. The paper determines that the NDT monitoring programme benefits outweigh its costs ($3·68–10·42 rate of return in repair savings for every dollar of investment in that programme). The paper also analyses the sensitivity of the outcome to key evaluation factors.

Novel ultrashort self-assembling peptide bioinks for 3D culture of muscle myoblast cells
Authors: Arab Wafaa , Rauf Sakandar , Al-Harbi Ohoud , A. E. Hauser Charlotte
Published: June 2018

The ability of skeletal muscle to self-repair after a traumatic injury, tumor ablation, or muscular disease is slow and limited, and the capacity of skeletal muscle to self-regenerate declines steeply with age. Tissue engineering of functional skeletal muscle using 3D bioprinting technology is promising for creating tissue constructs that repair and promote regeneration of damaged tissue. Hydrogel scaffolds used as biomaterials for skeletal muscle tissue engineering can provide chemical, physical and mechanical cues to the cells in three dimensions thus promoting regeneration. Herein, we have developed two synthetically designed novel tetramer peptide biomaterials. These peptides are self-assembling into a nanofibrous 3D network, entrapping 99.9% water and mimicking the native collagen of an extracellular matrix. Different biocompatibility assays including MTT, 3D cell viability assay, cytotoxicity assay and live-dead assay confirm the biocompatibility of these peptide hydrogels for mouse myoblast cells (C2C12). Immunofluorescence analysis of cell-laden hydrogels revealed that the proliferation of C2C12 cells was well-aligned in the peptide hydrogels compared to the alginategelatin control. These results indicate that these peptide hydrogels are suitable for skeletal muscle tissue engineering. Finally, we tested the printability of the peptide bioinks using a commercially available 3D bioprinter. The ability to print these hydrogels will enable future development of 3D bioprinted scaffolds containing skeletal muscle myoblasts for tissue engineering applications. 
Film education in Europe: National cultures or European identity?
Authors: Reid Mark
Published: June 2018

This paper considers the extent to which European countries have distinctive models and approaches to film education, and the extent to which a supranational model of European film education might exist in competition with those national models. It considers where film education is
positioned in relation to other subject fields and disciplines (literacy and media literacy); the role of the European Commission in promoting both European and national approaches to film education; and the potential of transnational film education programmes to move between national and
supranational film education cultures. It draws on data collected for Screening Literacy, a survey of film education funded by the European MEDIA programme that was carried out in 2012.

Published: June 2018

The present study was conducted to know the genetic diversity of three Saudi sheep populations; Naeimi (NM), Herri (H) and Najdi (NJ). Genomic DNA was extracted from 156 animals of sheep comprising 47 Naeimi, 47 Herri and 62 Najdi breeds using 18 microsatellite markers. A total of 212 alleles were generated with a mean value of 11.80 alleles per locus, with a range of observed and expected heterozygosity of 0.505 to 0.875 and 0.595 to 0.854, respectively. Eleven of the microsatellites loci studied in NM, three loci in H and fifteen loci in NJ were observed to be deviated from Hardy-Weinberg equilibrium. The fixation genetic indices (Fst) among the three sheep populations were very low, ranging from 0.017 (between NJ and H) to 0.033 (between NJ and NM), indicating low population differentiation among the three sheep populations studied. The present study showed that the microsatellite markers are powerful tool in determining genetic diversity among sheep populations.
The psychometric properties of the Big Five inventory-10 (BFI-10) including correlations with subjective and psychological well-being
Authors: Balgiu Beatrice Adriana
Published: June 2018

The article sums up the results of a psychometric study carried out on a sample of Romanian students (N = 496; 193 females) in order to assess the psychometric qualities of Big Five Inventory-10 (BFI-10). The questionnaire measures the 5 factors of personality from the Five Factors model. The convergent validity is demonstrated by the fact that BFI-10 correlates with the measures for: subjective well-being like happiness, life satisfaction, positive and negative affect and psychological well-being and its dimensions. Internal consistency is acceptable given that we evaluated an extra-short scale with two items per factor, although much reduced in comparison with the instruments with a large number of items. The confirmatory factorial analysis revealed a five-factor structure similar to the original structure with the modification of the factors Extraversion, Agreeableness, and Neuroticism. We consider that the application of BFI-10 must be accompanied and correlated with other instruments when it comes to assessing personality. It is necessary that the instrument BFI-10 should be perfected by redefining the items it contains.
On Galois extension of a separable algebra
Authors: Xuea Lianyong
Published: June 2018

Let \(B \) be a Galois extension of \(B^G \) with Galois group \(G \) such that \(B^G \) is a separable \(C^G \)-algebra where \(C \) is the center of \(B \). Then, for a subgroup \(H \) of \(G \), \(B\supset B^H \) is a Hirata separable Galois extension with Galois group \(H\) if and only if \(H\subset K \) where \(K=\{g\in G\,|\,g(c)=c \) for each \(c\in C\} \). Moreover, for \(H\not\subset K \) and \(H\cap K\not=\{e\} \), it is shown that \(B^{H\cap K}\supset B^H \) is the unique minimal Galois extension with Galois group \(H/H\cap K\) in \(B\supset B^H \) such that \(B\supset B^{H\cap K} \) is a Hirata separable Galois extension with Galois group \({H\cap K}\).

Authors: Martins Jefferson Dos Santos , Parreira Mariana Casari , Ribeiro Rafael Coelho , Silva Evaldo Morais da
Published: June 2018

O cultivo de raízes de mandioca é muito importante nas regiões do Brasil, principalmente por pessoas de baixa renda. Apesar do aumento da área plantada, a produtividade desta cultura é baixa, devido principalmente a baixa fertilidade e manejo dos solos utilizados para o plantio. Este trabalho teve como objetivo avaliar a influencia do calcário na cultura da mandioca no Nordeste Paraense (Amazônia Tocantina). O experimento foi realizado sob condições de campo, no período de novembro de 2015 a setembro de 2016, em uma propriedade rural de caráter familiar no município de Cametá, estado do Pará. O experimento foi conduzido em delineamento em blocos casualizados – DBC, com quatro repetições. Os tratamentos utilizados foram dosagens crescentes de calcário: 500 kg ha-1; 750 kg ha-1; 1.000 kg ha-1; 1.500 kg ha-1, mais uma testemunha sem aplicação. A cultura foi conduzida de acordo com os produtores familiares da Amazônia Tocantina, sem irrigação e adubação complementares. Foram avaliados: comprimento, diâmetro, número e peso de raízes por planta, produção total de raízes e também a quantificação de ácido cianídrico. Verificou-se que o maior peso de raízes por planta e a máxima produção foram obtidos utilizando a menor dosagem. A quantidade de ácido cianídrico nas raízes não foi diminuída com o aumento das doses de calcário, sendo a cultivar utilizada, classificada como mandioca mansa ou de mesa.
Exploration and attribution of synergistic gains from joint optimal operation of downstream Jinsha River cascade and Three Gorges cascade reservoirs for hydropower generation

Published: June 2018

Joint operation for multi-reservoir systems leads to synergistic gains. This study aims to explore and attribute the driven mechanism of synergism from joint operation of a multi-hydropower system. It quantified synergistic gains in spatial, temporal, and interannual scales by establishing and solving an individual and a joint reservoir operation model. It then proposed an attribution method for identifying the contribution of water released and water head to synergistic gains using total differential equation. Results of the case study of the downstream Jinsha River cascade and Three Gorges cascade reservoirs during the drawdown season show that: (1) synergistic gains generally occur in May and are mostly generated in Xiangjiaba and Gezhouba; (2) joint reservoir operation is driven by the rapid drawdown policy of Xiluodu and the Three Gorges in early May, which lowers down their water head and gains for most cases; (3) the main contribution factor to synergistic gains of Xiangjiaba and Gezhouba are water released and water head, respectively; and (4) the influence mechanisms of synergistic gains of Xiangjiaba and Gezhouba are jointly determined by their storage and power release capacity conditions. The study provides new insights for analyzing synergism of joint hydropower operations.

Indicadores del decaimiento en bosques de Nothofagus pumilio en el norte de la Patagonia, Argentina
Authors: Rodríguez-Catón Milagros , Villalba Ricardo
Published: June 2018

El decaimiento forestal está frecuentemente asociado a la mortalidad parcial o total de las copas en un alto porcentaje de individuos de un rodal. Si bien el decaimiento ha sido documentado a escala global, las relaciones entre las condiciones externas de los árboles y su crecimiento radial raramente han sido exploradas. El presente trabajo relaciona la intensidad del decaimiento con el crecimiento radial en 294 árboles de Nothofagus pumilio en el norte de la Patagonia. Los indicadores externos del decaimiento analizados fueron la mortalidad de la copa, la sanidad de la corteza, la incidencia de insectos barrenadores y pájaros carpinteros, así como la presencia de plantas hemiparásitas, hongos y líquenes. Los resultados indican que elevados porcentajes de mortalidad de copa están significativamente relacionados con la disminución del crecimiento radial promedio, siendo esta relación más notoria cuando se usa como medida del crecimiento radial el incremento en área basal en lugar del ancho de los anillos. El deterioro de la corteza y la abundancia de cavidades producto de las actividades de insectos barrenadores y de pájaros carpinteros también estuvieron significativa e inversamente relacionados con el crecimiento. Por el contrario, el crecimiento y la presencia de hemiparásitas, hongos o líquenes no mostraron relaciones significativas. A partir de estos resultados, se propone utilizar en la estimación de la sanidad forestal los indicadores externos (1) mortalidad de copa, (2) deterioro de la corteza y (3) cavidades de insectos y/o pájaros carpinteros, como una medida integral del decaimiento forestal de Nothofagus pumilio en la Patagonia.
GREEN LOGISTICS : ECO-FRIENDLY MEASURE IN SUPPLY-CHAIN
Authors: Purnendu Kumar Patra
Published: June 2018

Green Logistics may be defined as the entire set of efforts taken by organisations to measure and minimize the environmental impact of logistics activities. Among other reasons why companies choose to go green, one major cause is that it gives the company a competitive advantage. Other reasons could be: to reduce traffic congestion, control pollution or to save transportation costs. Logistics is the backbone of globalization process but unfortunately, it takes a toll on the planet. Technological advancements have improved the cost, efficiency and reliability of transportation systems but the negative environmental impacts of transportation have generated much attention and are at the core of issues of sustainability. The term “logistics” denotes the degree of coordination and control over shipments and has become one of the most important developments in transportation. Green has become a buzz word for a range of environmental concerns. When put together, the two words point towards an eco-friendly, efficient transport and distribution system. It describes all attempts to measure and minimize the ecological impact of logistics activities. This includes all activities of forward and reverse flows of products, information and services between the point of origin & point of consumption. This paper is an attempt to look at green logistics from an industry point of view. Doing thus, it is hoped to make the industry see business sense in adopting and implementing eco-friendly measures in their colossal supply chains. A new model supported by adequate literature review has been proposed with an aim to convey to the stakeholders that there is perfect rationale in accepting modern green practices without sacrificing any of their econometric performance indicators. The method adopted is that of analysis of existing literature coupled with a proposal to enhance the efficiency ofthe existing traditional supply chain system.
OCCUPATIONAL STRESS AT WORKPLACE : A CASE STUDY OF PRIVATE COLLEGES IN VARANASI
Authors: Anchal Pathak
Published: June 2018

The main focus of the study is to ascertain the stress amongst the faculties of higher education in private colleges at Varanasi. It has been found that high level of occupational stress can cause irritation, anxiety, ineffectiveness, depression and lower job satisfaction. The key objective of this study was to assess the level of occupational stress, causes and consequences among the faculties. Among the twelve occupational stressors gauged in the study, using Occupational Stress Index by A.K. Srivastava and A.P. Singh, role overload & role conflict was found to be with maximum variance among the faculties. It has also been observed that unfair distribution of work and under participation influences satisfaction and well being of faculty members at workplace in Varanasi. Implications of this research from the perspective of better stress management among faculty members are discussed.
CpG islands’ clustering uncovers early development genes in the human genome
Authors: Babenko Vladimir , Bogomolov Anton , Babenko Roman , Galieva Elvira , Orlov Yuriy
Published: June 2018

We address the problem of the annotation of CpG islands (CGIs) clusters in the human genome. Upon analyzing gene content within CGIs clusters, piRNA, tRNA, and miRNA-encoding genes were found as well as CpG-rich homeobox genes reported previously. Chromosome-wide CGI density is positively correlated with replication timing, confirming that CGIs may serve as open chromatin markers. Early embryonic stage expressed KRAB-ZNF genes abundant at chromosome 19 were found to be interlinked with CGI clusters. We detected that a number of long CGIs and CGI clusters are, in fact, tandem copies with multiple annotated macrosatellites and paralogous genes. This finding implies that tandem expansion of CGIs may serve as a substrate for nonhomologous recombination events.

polyethylene (PE-LD) that could be obtained over a very wide range of
polymerization conditions. The method was proved using experimental data
from the literature. However, some shortcomings of the method were noticed.
The aim of this work was to overcome the shortcomings and to enable the
better manipulation of experimental data using a computer. A computer
program has been developed to establish the mathematical relationships
between ethylene entropy and the structural parameters and density of Pe-LD.
All available experimental data (more than 300 experimental points) have
elaborated and confirmed our mathematical models and our theoretical
predictions.

The reaction of copigmentation of malvidin 3,5-diglucoside and tannic acid of
the ester type was studied. The interactions of these molecules were
observed via UV-VIS absorption spectroscopy. It was established that the pH
of the medium, the concentration of the copigmentating molecules, and the
temperature affect the copigmentation process. The calculated equilibrium
constant of the reaction of pH 3.00 is K = 226.9, and at pH 3.65 it is K =
277.0. The change of the Gibbs free energy in pH 3.00 buffer is ?G =-13.4
kJ/mol, and in pH 3.65 buffer it is DG =-13.9 kJ/mol. The stoichiometric
ratio of the components in the copigment is 1:1, at both pH values. It is
evident from the calculated values of the thermodynamic functions that the
process is thermodynamically favorable in the lower temperature range.
Temperature appears as the basic parameter of the thermodynamic feasability
of the process, since the copigmentation process is exothermic (?HpH=3.00
= -41.6 kJ/mol and ?HpH=3.65 = -41.6 kJ/mol) and proceeds with a decrease
in entropy (?SpH=3.00 = -94.4 J/mol K and ?SpH=3.65 = -92.7 J/mol K).
Oxygen reduction on single crystal platinum electrodes in phosphoric acid solutions
Authors: Tanaka A. , Adzic R. , Nikolic B.
Published: June 2018

Oxygen reduction reaction has been studied on Pt low index planes in 0.1Mand
85% H3PO4 using hanging meniscus rotating disc electrode technique. The
first-order kinetics of O2 reduction reaction was found for all three
surfaces in a four-electron process with the first electron transfer rate
determining in both 0.1 M and 85% H2PO4 solutions. Catalytic activity for O2
reduction follows the sequence Pt (110)>Pt (100)>Pt (111). Structural
dependence is predominantly determined by the adsorption of phosphoric
acid anions, which is strongly structure-dependent on Pt surfaces.
Monilukutaitoa monitaiteisesti

Published: June 2018

Perusopetuksen uudistetun opetussuunnitelman (POPS, 2014) yksi laaja-alaiseen osaamiseen liittyvä tavoite on monilukutaidon kehittäminen, jolla tähdätään siihen, että oppilaat kykenevät tuottamaan ja tulkitsemaan erilaisia tekstejä eri tavoilla. Lukutaitotutkimuksessa asiaan viitataan puhumalla erilaisista modaliteeteista, tavoista ja keinoista kommunikoida ja representoida sisältöjä esimerkiksi visuaalisesti, kinestiteettisesti, auditiivisesti, numeraalisesti sekä modaliteettien yhdistelmiä käyttämällä (monimodaalisuus, multimodaalisuus).

Tässä artikkelissa tarkastelemme perusopetuksen yhdeksännellä luokalla toteutettua musiikin ja tanssin opetuskokonaisuutta monilukutaidon kehittymisen tukemisen näkökulmasta. Tavoitteenamme on ymmärtää, miten monilukutaito ilmenee ja miten sitä voidaan tukea oppiaineissa, joiden perusta on moniaistisuudessa, itseilmaisussa ja kehollisuudessa.

Selvitämme tapaustutkimuksen keinoin, millaisia monilukutaidon – erityisesti monimodaalisen lukutaidon – ilmentymisen ja kehittymisen tukemisen kannalta relevantteja merkityksiä yläkoulun oppilaat tuottavat tanssikoreografian luomisprosessissa tekijänä ja katsojana, sekä miten he reflektiivisesti analysoivat havaitsemiaan merkityksiä.
Un mosaico de lenguas: los intérpretes de la Audiencia de México en el siglo XVI
Authors: Cunill Caroline
Published: June 2018

En Laberintos de justicia Víctor Gayol analizó los oficios menores que permitían que la Real Audiencia de México impartiera justicia en los territorios bajo su jurisdicción. No obstante, el historiador dejó a un lado un oficio de suma importancia para comprender el funcionamiento de esta institución: los intérpretes de las lenguas indígenas. ¿Cuántas lenguas autóctonas se hablaban en la Audiencia de México? ¿Quién desempeñó las funciones de intérprete? ¿Eran indígenas, españoles o mestizos? ¿En qué circunstancias estas personas llegaron a ser bilingües? Para contestar a estas interrogantes el presente trabajo analiza una serie de nombramientos de intérpretes otorgados por la Audiencia de México, así como las probanzas de méritos y servicios que algunos titulares enviaron al Consejo de Indias, de manera individual o colectiva, para dar a conocer su trabajo y solicitar mercedes. Gracias a esta documentación, se ofrece una cronología de la ocupación del cargo en el siglo XVI y un análisis del perfil social y étnico de sus titulares. Consideramos que esta reflexión permite entender mejor el proceso de adaptación de las instituciones del Imperio hispánico a la realidad plurilingüística del continente americano.
La historia contemporánea de México y la historia global: reflexiones acerca de los “sesenta globales”
Authors: Scheuzger Stephan
Published: June 2018

A pesar de la abundancia de publicaciones sobre el “68” en México que abarcan también sus antecedentes, causas y contextos, sorprende lo poco que se sabe tanto sobre el significado exacto de los entrelazamientos transnacionales para los sucesos en México como sobre la relación entre la contracultura y la política en el desafío del orden establecido. La presente contribución no tiene como objetivo llenar estas lagunas. Ampliando la perspectiva hacia la idea de los global sixties, el presente artículo más bien propone una reflexión sobre lo que pueden significar los planteamientos de la historia global tanto para la comprensión de un período considerado como decisivo para el transcurso de la historia contemporánea mexicana como para la interpretación de fenómenos históricos en muchas otras partes del mundo. Este sondeo se hace a la luz del diagnóstico de que la historia de América Latina, y particularmente su historia contemporánea, ha quedado hasta ahora al margen de la coyuntura de la historia global. El análisis de los años sesenta se presta para dar uno de los primeros pasos en la dirección de una mayor integración de la historia latinoamericana en general y de la historia mexicana en particular en las perspectivas de la historia global. El objetivo de esta integración consiste en llegar a una mejor comprensión no sólo de lo que sucedió en México o en otros países del subcontinente y del mundo, sino también de procesos más allá de los marcos nacionales de la historia.

OBJECTIVE To determine survival time and metastatic rate for dogs with early-stage anal sac adenocarcinoma (ASACA) treated with surgery alone and assess whether specific clinical, pathological, or immunohistochemical factors were predictive of outcome for those dogs.

DESIGN Retrospective case series.

ANIMALS 34 dogs with early-stage, nonmetastatic ASACA that were treated with surgery only.

PROCEDURES Medical record databases of 2 referral hospitals were searched to identify dogs examined between 2002 and 2013 that had a diagnosis of nonmetastatic ASACA that was < 3.2 cm at its largest diameter. Only dogs that received surgical treatment alone were included in the study. For each dog, information extracted from the medical record included signalment, clinical and diagnostic test findings, tumor characteristics, and outcome. When available, archived tumor specimens were histologically reviewed and tumor characteristics were described; Ki-67 and E-cadherin expressions were evaluated by use of immunohistochemical methods. Clinical, pathological, and immunohistochemical factors were assessed for associations with survival time and tumor recurrence and metastasis rates.

RESULTS Median survival time was 1,237 days. Seven dogs had tumor recurrence and 9 dogs developed metastatic disease at a median of 354 and 589 days, respectively, after primary tumor removal. Cellular pleomorphism was positively associated with development of metastatic disease. No other factors evaluated were associated with outcome.

CONCLUSIONS AND CLINICAL RELEVANCE Results indicated dogs with early-stage nonmetastatic ASACA generally had a favorable outcome following surgical removal of the primary tumor alone. Routine rectal examination may be a simple and useful method for detection of dogs with early-stage ASACA.
Elucidating the Role of Isotopically Chiral Initiators in the Soai Asymmetric Autocatalytic Reaction
Authors: Hawbaker Neil , Blackmond Donna
Published: June 2018

A mechanistic rationalization is given for how asymmetric amplification is induced with fidelity in the Soai autocatalytic reaction by chiral initiators that are enantiomeric only by virtue of an isotope, e.g. – CH3 vs.CD3. A transient inhibition of the autocatalytic pathway at the outset of the reaction implicates an interaction between initiator and product initially formed in the uncatalyzed background reaction. Selectivity in formation of the product-initiator complex ultimately induces a slight enantioenrichment in the active dimer catalysts that trigger and direct the autocatalytic pathway.
Is Pokémon GO Feminist? An Actor-Network Theory Analysis
Authors: Assuncao Carina
Published: June 2018

The Pokémon franchise has been targeted and has been successful with males and females (Tobin, 2004). In it, cute-looking creatures with superpowers fight each other for the fame and glory of their masters (the players). The franchise includes a plethora of entertainment media. This essay will focus on the recent release, Pokémon GO. This particular game and its location-based technology will be analysed using cyberfeminism and actor-network theory to explore the play space as a context for kinaesthetic awareness and embodiment. The cyberfeminism herein exploited is that of “the utopian tradition of imagining a world without gender” (Haraway, 2000, p. 292). Actor-network theory, a strong methodological tradition in science and technology studies, sees actors and the networks they create as completely ‘flat’ and non-hierarchical. ANT has been criticised for its lack of concern with politics and gender (Lagesen, 2012) but, in combination with a feminist lens, ANT has the potential to uncover issues that other approaches in game studies cannot. This original framework can help game studies scholars to see gameplay processes in a new light by following the many actors involved in game design and use.
