The TMAI Model – Performance Of Portfolios Constructed On The Base Of Correlated And Uncorrelated Financial Ratios
Authors: Węgrzyn Tomasz
Published: June 2015

The author studies portfolio performance. Companies are chosen to portfolios due to their position in the ranking that is constructed on the base of the chosen financial ratios. There are three rankings constructed on different number of financial ratios. Each ranking is constructed on the base of synthetic measure of development. The TMAI ranking is constructed on the base of 48 financial ratios, the TMAI_gr1 ranking is constructed on the base of 14 financial ratios that can be correlated and the TMAI_gr2 ranking is constructed on the base of 8 uncorrelated financial ratios. The author uses data of companies listed on the Warsaw Stock Exchange between 2005 and 2011. The rankings and portfolios are built separately for each year. As a result, it can be stated that the Portfolio 3 in the TMAI_gr1 ranking is the best portfolio for investors who are maximizing the Sharpe ratio.

Published: June 2015

The development of light-sensitive media based on organic, mostly heterocyclic compounds that have no fluorescence in their initial form but provide fluorescent photoproducts formation is considered in this review. Materials with photoinduced irreversible fluorescence appear to be the most promising in the design of recording media for 3D archive optical memory. Photoactivatable fluorophores are also of interest for use in cell biology.

Comparison of Cardiovascular Risk Screening Methods and Mortality Data Among Hungarian Primary care Population: Preliminary Results of the First Government-Financed Managed care Program / Primerjava Metod Presejanja Ogroženosti Srčno-Žilnega Sistema In Podatkov O Smrtnosti Madžarskega Prebivalstva Z Osnovno Zdravstveno Oskrbo: Predhodni Rezultati Prvega Programa Vodene Oskrbe, Ki Ga Je Financirala Vlada
Authors: Móczár Csaba , Rurik Imre
Published: June 2015

Introduction. Besides participation in the primary prevention, screening as secondary prevention is an important requirement for primary care services. The effect of this work is influenced by the characteristics of individual primary care practices and doctors’ screening habits, as well as by the regulation of screening processes and available financial resources. Between 1999 and 2009, a managed care program was introduced and carried out in Hungary, financed by the government. This financial support and motivation gave the opportunity to increase the number of screenings.

Method. 4,462 patients of 40 primary care practices were screened on the basis of SCORE risk assessment. The results of the screening were compared on the basis of two groups of patients, namely: those who had been pre-screened (pre-screening method) for known risk factors in their medical history (smoking, BMI, age, family cardiovascular history), and those randomly screened. The authors also compared the mortality data of participating primary care practices with the regional and national data.

Results. The average score was significantly higher in the pre-screened group of patients, regardless of whether the risk factors were considered one by one or in combination. Mortality was significantly lower in the participating primary practices than had been expected on the basis of the national mortality data.

Conclusion. This government-financed program was a big step forward to establish a proper screening method within Hungarian primary care. Performing cardiovascular screening of a selected target group is presumably more appropriate than screening within a randomly selected population. Both methods resulted in a visible improvement in regional mortality data, though it is very likely that with pre-screening a more cost-effective selection for screening may be obtained.
Some Complex Compounds of Neptunium (IV) and Related Ions
Authors: Ishimori Tomitaro , Nakamura Eiko
Published: June 2015

The phenylarsonate, oxalate, mandelate and ethylenediaminetetraacetate of neptunium (IV) were radiochemically surveyed by the solvent extraction technique. An equation given by SCHUBERT as well as another one evolved by ISHIMORI for the composition of complex compounds, were applied to the measured distribution ratios in a di-(2-ethyl-hexyl)-phosphoric acid-hydrochloric acid system containing a complexing agent. The determined molar ratios of the complexing agents: neptunium (IV) were 2, 4 and 1 for phenylarsonate, oxalate and ethylenediaminetetraacetate, respectively. No mandelate of neptunium (IV) was observed in the acidity range studied. The dissociation constants for most of the complex compounds were calculated.
Hot Electron Chemistry
Authors: Walton G. N.
Published: June 2015

Some features of the present position on theories of the chemical effects of nuclear transformation are briefly reviewed. It is suggested that theories based on the transfer of energy by elastic collisions of recoiling atoms are not adequate to explain many of the experimental observations. Instead it is shown that electronic excitation, the transfer of energy between electrons, and the consequent loss of valency bonding or its rearrangement, are likely to be of primary importance for explaining these effects.

Spaltproduktabgabe von beschichteten Brennstoffpartikeln nach der Reaktor-Bestrahlung
Authors: Riedel H. J.
Published: June 2015

Bei dem Betrieb von gasgekühlten Hochtemperatur-Reaktoren werden mit Pyrokohlenstoff und Siliciumcarbid beschichtete Kernbrenn- und Brutstoffe verwendet. Das Rückhaltevermögen dieser Umhüllungen für gasförmige und feste Uranspaltprodukte, sowie der Transport der Spaltprodukte durch den die Partikeln umgebenden Graphit bestimmt den möglichen Grad einer Kontamination des Kühlkreislaufs.

Im Rahmen eines Nachuntersuchungsprogramms über das Verhalten verschiedener Partikeltypen in Abhängigkeit von der Betriebstemperatur, dem Abbrand und der geometrischen Unterbringung der Partikeln, untersuchten wir radiochemisch die Spaltproduktverteilung in dem die Partikeln umgebenden Graphit.

Für die analytische Trennung und Bestimmung der Spaltelemente bedienten wir uns der Destillation, der Fällung, der Flüssigkeitsextraktion und der Ionenaustauschtechnik. Die Methoden werden kurz beschrieben. Auf diese Weise können 12 Spaltnuklide bestimmt werden. Eine auffällig hohe Beweglichkeit wurde für die Spaltelemente Ba, Sr und Y beobachtet. Die Abgabe von anderen Spaltprodukten mit hoher Spaltausbeute liegt wesentlich tiefer.

Einige die Spaltproduktabgabe beeinflussenden Parameter werden diskutiert.
Migrantes latinoamericanos más allá de la frontera norte
Authors: Vejar Pérez-Rubio Carlos
Published: June 2015

El tema de los migrantes latinoamericanos en Estados Unidos y Canadá es analizado en este ensayo partiendo del concepto antropológico de los viajes, que han estado asociados siempre al género humano, en todas las culturas y ámbitos geográficos, desde los nómadas de la prehistoria hasta los turistas de la actualidad. Se advierte en el análisis que este fenómeno ha sido crucial para el desarrollo de las diversas civilizaciones, que se han forjado en buena medida con el tránsito e incorporación de individuos y grupos ajenos, si bien muchas veces con problemas, como es el caso hoy en día de la masiva corriente de migrantes que pasan de los países subdesarrollados a los desarrollados en busca de condiciones adecuadas para una vida digna, inaccesible en sus países de origen. Los millones de trabajadores migrantes de Latinoamérica que se encuentran en Estados Unidos y Canadá son un buen ejemplo de ello.

Published: June 2015

O presente estudo teve o objetivo de avaliar o equilíbrio Ca/Mg na correção da acidez do solo e medir o efeito da aplicação do potássio sobre a produção de matéria seca do milho, num experimento conduzido sob casa de vegetação em vasos de plástico com Latossolo Amarelo, álico, distrófico. O delineamento experimental utilizado foi em blocos ao acaso, em esquema fatorial (4 χ 3), com quatro repetições. Os tratamentos constituíram de quatro equilíbrios em % de Ca e Mg (100/0; 75/25; 50/50; e 25/75) e três doses de potássio (0; 100 e 200 mg.kg-1 de terra) na forma de cloreto de potássio. A aplicação do corretivo sob a forma de reagentes puros (carbonato de cálcio e carbonato de magnésio) foi realizada 21 dias antes do plantio, e os nutrientes foram aplicados na forma de solução. A colheita do experimento foi realizada aos 45 dias após o plantio. Determinaram-se as produções de matéria seca e os teores de K, Ca e Mg. Os resultados demonstraram que, as produções máximas foram obtidas quando o pH foi de 6,3; o teor de cálcio de 27,5 mmolcdnr-3; o teor de magnésio de 18,0 mmolcdnr-3; a relação (Ca + Mg)/K igual a 19,8 e a relação Ca/Mg no corretivo foi de 1,1/1. A relação Ca/Mg no solo foi um dos principais fatores que alterou a produção. As doses de potássio proporcionou aumento quadrático e significativo, independente das doses de calagem empregadas e das relações Ca/Mg utilizadas. Doses crescentes de potássio, reduziu o acúmulo do magnésio na parte aérea das plantas de milho.
Two cytotypes and a new hybrid in Salvinia Séguier
Authors: SOTA Elias R. DE LA , PAZOS Liliana A. CASSÁ DE
Published: June 2015

Two cytotypes (2n=4x=36 and 2n=6x=54) found in Salvinia minima Bak. are discussed, the first from Brazil and the second from Argentina. The hexaploid cytotype, presumably a hybrid between Salvinia minima and S. sprucei Kuhn, was collected from the Solimões River near Manaus, Brazil and from Trinidad. Discussing its intermediate morphology, the authors attemp to explain the hybridization as a result of the seasonal and sporadic occurrence of Salvinia sprucei in the Amazonian basin, assuming that the still unknown chromosome number of the latter species would correspond to the diploid level (2n=2x=18).

Published: June 2015

OBJECTIVE: This study aimed to assess the nutritional status of vitamin A and associated factors in children assisted in Primary Care Health in Goiânia, Goiás, Brazil. METHODS: This is a cross-sectional study with a sample of 228 children 12 to 16 months of age. The nutritional status of vitamin A was assessed by serum retinol concentration, determined by high performance liquid chromatography. Multiple linear regression models with hierarchical selection of independent variables were used to evaluate the correlation with serum retinol as the dependent variable. RESULTS: The vitamin A deficiency (retinol < 0,7 μmol/L) was observed in 14,0% of the children. Maternal schooling and hemoglobin concentration were positively correlated with serum retinol concentration, while C-reactive protein showed a negative correlation (R2 = 0,1648). CONCLUSION: The vitamin A deficiency in one-year-old children attended in Basic Health Units in Goiânia configures itself as a moderate public health problem. Actions to promote maternal education, morbidity control and prevention of other micronutrient deficiencies are important for prevention and control of the vitamin A deficiency in this population.

Radiographie de l’immersion dans l’enseignement supérieur en Suisse et à l’Université de Fribourg : les pré-requis nécessaires
Authors: Gohard-Radenkovic Aline
Published: June 2015

De nos jours, la notion d’immersion est le plus souvent liée à celle d’éducation bilingue, proposant des dispositifs qui réinventent en quelque sorte l’appropriation naturelle d’une langue étrangère ou seconde dans le cadre de politiques linguistiques officielles. Toutefois l’immersion naturelle en langues existe depuis le Moyen-Âge en Europe, notamment en Suisse, surtout dans les régions frontalières. Que s’est-il passé entre-temps pour que le dispositif de l’immersion soit devenu l’atout majeur au service de cette éducation bilingue ? Après avoir brièvement rappelé les différentes conceptions et réalisations de l’immersion, nous examinerons les dispositifs existants de l’immersion dans l’enseignement supérieur en Suisse. Nous nous arrêterons à l’Université officiellement bilingue de Fribourg (français–allemand) où nous analyserons les offres d’immersion, plus spécifiquement le programme Bilingue Plus. Enfin nous nous demanderons quels sont les pré-requis de cette éducation au bi/plurilinguisme à l’heure où les apprenants pourraient simplement se contenter de l’apprentissage d’une seule langue, l’anglais.
Racial/Ethnic Differences in Combat- and Non–Combat-Associated Traumatic Brain Injury Severity in the Veterans Health Administration: 2004–2010
Authors: Dismuke Clara E. , Gebregziabher Mulugeta , Yeager Derik , Egede Leonard E.
Published: June 2015

Objectives. We examined the association between traumatic brain injury (TBI) severity and combat exposure by race/ethnicity.

Methods. We estimated logit models of the fully adjusted association of combat exposure with TBI severity in separate race/ethnicity models for a national cohort of 132 995 veterans with TBI between 2004 and 2010.

Results. Of veterans with TBI, 25.8% had served in a combat zone. Mild TBI increased from 11.5% to 40.3%, whereas moderate or severe TBI decreased from 88.5% to 59.7%. Moderate or severe TBI was higher in non-Hispanic Blacks (80.0%) and Hispanics (89.4%) than in non-Hispanic Whites (71.9%). In the fully adjusted all-race/ethnicity model, non-Hispanic Blacks (1.44; 95% confidence interval [CI] = 1.37, 1.52) and Hispanics (1.47; 95% CI = 1.26, 1.72) had higher odds of moderate or severe TBI than did non-Hispanic Whites. However, combat exposure was associated with higher odds of mild TBI in non-Hispanic Blacks (2.48; 95% CI = 2.22, 2.76) and Hispanics (3.42; 95% CI = 1.84, 6.35) than in non-Hispanic Whites (2.17; 95% CI = 2.09, 2.26).

Conclusions. Research is needed to understand racial differences in the effect of combat exposure on mild TBI and on interventions to prevent TBI across severity levels.
Considerations Before Establishing an Environmental Health Registry
Authors: Antao Vinicius C. , Muravov Oleg I. , Sapp James , Larson Theodore C. , Pallos L. Laszlo , Sanchez Marchelle E. , Williamson G. David , Horton D. Kevin
Published: June 2015

Public health registries can provide valuable information when health consequences of environmental exposures are uncertain or will likely take long to develop. They can also aid research on diseases that may have environmental causes that are not completely well defined.

We discuss factors to consider when deciding whether to create an environmental health registry. Those factors include public health significance, purpose and outcomes, duration and scope of data collection and availability of alternative data sources, timeliness, availability of funding and administrative capabilities, and whether the establishment of a registry can adequately address specific health concerns.

We also discuss difficulties, limitations, and benefits of exposure and disease registries, based on the experience of the Agency for Toxic Substances and Disease Registry.
Life-Course Partnership Status and Biomarkers in Midlife: Evidence From the 1958 British Birth Cohort
Authors: Ploubidis George B. , Silverwood Richard J. , DeStavola Bianca , Grundy Emily
Published: June 2015

Objectives. We examined the association between trajectories of partnership status over the life course and objectively measured health indicators in midlife.

Methods. We used data from 4 waves (1981, 1991, 2000, and 2002–2004) of the British National Child Development Study (NCDS), a prospective cohort study that includes all people born in Britain during 1 week in March 1958 (n = 18 558).

Results. After controlling for selection attributable to early-life and early-adulthood characteristics, we found that life-course trajectories of partnership status were associated with hemostatic and inflammatory markers, the prevalence of metabolic syndrome and respiratory function in midlife. Never marrying or cohabiting was negatively associated with health in midlife for both genders, but the effect was more pronounced in men. Women who had married in their late 20s or early 30s and remained married had the best health in midlife. Men and women in cohabiting unions had midlife health outcomes similar to those in formal marriages.

Conclusions. Partnership status over the life course has a cumulative effect on a wide range of objectively measured health indicators in midlife.

Authors: Masuduzzaman M , Raman ML , Hossain MA
Published: June 2015

An investigation was carried out on incidence and pathology of fascioliasis in deer of Chittagong Zoo and some houses of Chittagong city during the period from January 2001 to June 2004. A total of 57 domesticated deer of various types were examined to diagnose the fascioliasis in Chittagong zoo and some house deer of Chittagong city. By faecal examination out of 44 cases 34 (77.3%) were positive for fascioliasis, of which, 15 (34.1%) cases were recorded in Chittra deer, 12 (27.3%) in Maya deer, 05 (11.4%) in Shambar deer and 02 (4.5%) in Nathrini deer. In post mortem examination, fascioliasis found in 13 (100%) cases, of which, 08 (61.5%) from Chittra deer and 05 (38.5%) from Maya deer. The overall incidence of fascioliasis in deer was 82.5%. In relation to sex the fasciolasis was significantly (p < 0.05) higher in female (82.6%) than male (71.4%) deer. The incidence of fascioliasis in various types of deer in relation to age was significantly (p < 0.05) higher in age group of above 2 years old than in age group below 2 years old. The gross examination revealed enlarged livers with round edges and thickened capsule with numerous haemorrhagic spots on the parietal surface (subacute form). In chronic form, the livers were cirrhotic and reduced in size. The affected intra-hepatic bile ducts were protruded and were engorged with flukes. Microscopically the migratory tracts were represented by the presence of haemorrhagic, oedema and infiltration with numerous eosinophils mixed with few lymphocytes. The wall of the bile ducts was thickened with fibrous tissue proliferation and the lining epithelium showed hyperplastic changes.

Att forma en medarbetare eller att undervisa en student
Authors: Johansson Mahic Maria , Skyvell Nilsson Maria
Published: June 2015

Genom cooperative education (co-op) ges studenter möjlighet att inom utbildningen, praktiskt tillämpa sina kunskaper på en arbetsplats. Under co-op tilldelas studenten en av arbetsgivaren utsedd handledare. Co-op är ett trepartssamarbete mellan högskola, student och arbetsplats. Merparten av tidigare studier fokuserar studenternas upplevelse av co-op eller vad co-op kan innebära för studentens studiemotivation, framtida karriär och möjlighet till arbete. Syftet med denna fenomenografiska studie är att beskriva handledares uppfattning om handlednings syfte. Studien kan därmed bidra till kunskap om den utbildningssituationen studenter ställs inför i co-op. Studiens resultat, som är baserad på intervjuer, visar fyra olika uppfattningar om handlednings syfte: Stödja in i gemenskapen, Delge specifikt kunskapsinnehåll, Att få möjlighet att lära och Bidra till produktionen. Handledarnas uppfattningar indikerar att studenten förväntas praktiskt tillämpa teoretisk kunskap och få arbets- och yrkesrelaterade erfarenheter genom ett socialt lärande. Variationerna i handledarnas uppfattningar antyder även att det samlade kunskapsinnehållet som studenten får ta del av under co-op kan variera stort. Utifrån resultatet diskuteras möjligheter och hinder för studentens lärande under co-op.
Integrating Social Media and Traditional CRM
Authors: Yoon Kanghyun , Sims Jeanetta D.
Published: June 2015

In recent years, marketers have paid lots of attention to a new field called social CRM, created from the combination of social media and traditional customer relationship management (CRM) practices. In the past, traditional CRM practices have mainly focused on the task of valuing individual customers' profitability through relationship management over time as the proxy of creating the firm's value. Shifting away from this trend, firms have recently attempted to promote customer engagement into the value creation process as the core of CRM strategy. This chapter proposes conceptual guidelines for the success of social CRM practices, while considering the development of personalized customer engagement programs with social media depending on customer status over the life cycle.
Adoption of Social Media Services
Authors: Sharif Mohd Hisham Mohd , Troshani Indrit , Davidson Robyn
Published: June 2015

The increasing diffusion of social media is attracting government organizations worldwide, including local government. Social media can help local government improve the manner in which it is engaged with community and its responsiveness whilst offering cost savings and flexibility. Yet, there is paucity of research in relation to the adoption of social media Web services in local government organizations. The aim of this chapter is to investigate the factors that drive the adoption of social media Web services within Australian local government. Using qualitative evidence, the authors find technological, organizational, and environmental factors that drive the decisions of local government organizations to adopt social media Web services. In addition to extending the existing body of knowledge, this chapter offers insight concerning important managerial implications for helping local governments to better understand social media adoption in their organizations.
Turkish Youth's (Re)Construction of their Political Identity in Social Media, before “Resistanbul”
Authors: Gülşen Tüge T.
Published: June 2015

This chapter explores the political potential of social media widely used as a means of communication by Turkish young people and examines how they perceive social media as alternative social environments, where they can manifest their political identities. In addition, the study conducted aims at understanding whether the political situation in Turkey before the “Resistanbul” events, beginning toward the end of May 2013, created fear among young people that could cause them to hesitate to express their political thoughts or feel the need to veil their political identities. The results of the survey reveals that Turkish young people, despite having a high sense of freedom, tend to be politically disengaged in social media, and they seem to be hesitant to reveal their political identities in this alternative democratic social space, but they do not mind “others” manifesting their political identities.

As a relatively new form of communication and information dissemination, the effect of social media on public awareness and public participation in political events is relatively unknown. Using the events that unfolded surrounding the election of Governor Scott Walker in Wisconsin and the removal of collective bargaining rights of public employees as its main example, this chapter explores the relationship between social media, information dissemination, and collective action.
Teachers' Use of Social Networking Sites for Continuing Professional Development
Authors: Xerri Daniel
Published: June 2015

On the basis of the results of a study conducted amongst secondary school teachers of English in Malta, this chapter explores the use of Social Networking Sites (SNS) for professional development purposes. In the digital era, SNS provide teachers with the opportunity of creating a Personal Learning Network (PLN), which is an increasingly significant way of acquiring new knowledge and enhancing pedagogical skills while also having the capacity of making teachers feel they belong to a Community of Practice (CoP). This chapter shows how despite their regular use of SNS for personal reasons, teachers do not always exploit these sites to achieve professional development. It is argued that training is a necessary means of not only enabling teachers to learn how to use such tools for such a purpose but also of redefining the way they think about the process of acquiring and sharing knowledge and skills in the 21st century.
Political Information, Political Power, and People Power
Authors: Alahmed Anas
Published: June 2015

This chapter explores the concept of new media in the Arab world and how politics in the information age has changed Arab politics and moved citizens to the streets. However, the evolution of new media social networks and the cause of political information in particular during the revolution is not studied alone. In fact, the evolution of the Arab Spring and the effects of new media social networks are taken into account by exploring how politics in the information age has influenced Arab citizens and allowed them to use information for the greater good and established such a new social movement. This chapter takes the Arab Spring as a case study and an empirical example to understand the transnational protests and global movements, the concept of global media and global politics in the case of the Arab Spring, new media and new politics regarding the Arab Spring, and city and street and public sphere as people power in the information age. Finally, the chapter distinguishes between the new social movements through social networks and the roles of ICTs to aim revolution and whether such a revolution will erupt without new media social networks.
Valorisation du biogaz par moteur à allumage commandé : Une approche méthodologique du dimensionnement
Authors: Bereza M. , Le Corre O. , Tazerout M.
Published: June 2015

The size of an electric power plant using biogaz has to be achieved by the development of a model designed to integrate fuel quality and quantity evolutions throughout life duration of the power plant. A description by “grey box” for the biogaz combustion in spark ignition engines allows to estimate the electric power output. The biogaz composition is featured by “typical days”. The investment decision is generally based on economical criteria, the electric trade, the investment and the maintenance costs are introduced. Results show the optimal power output to install according to the available biogaz flow-rate. The “bottom price” for the electric power, which is the minimum price beneath such a project can not make any profit, is presented.

Le dimensionnement d'une installation de production d'électricité utilisant du biogaz nécessite de mettre au point un modèle permettant d'intégrer les changements de quantité et de qualité du combustible durant la durée de vie de l'installation. Une description de type « boite grise » de la combustion du biogaz dans les moteurs à allumage commandé permet d'obtenir la puissance électrique produite en fonction du combustible. Les caractéristiques du biogaz sont modélisées par « journées types ».

Authors: Boidot-Forget Marc , Monier Véronique
Published: June 2015

Ecobilan has developed a software tool designed to assess the environmental burdens of any collection-sorting-downstream treatment scheme of any domestic waste. The tool allows any comparison between alternative waste management scenarios, including incineration, recycling, landfilling. A special emphasis is put on the user's interface, which enables easy and quick navigation through the tool. The construction of the system and the calculations are automatically performed upon request by TEAMTM, Ecobilan's Life Cycle Assessment software tool. Sets of graphics can be generated and give insight into the inventory of the flows (around 150 are listed) and into a large set of environmental impacts (around 20 can be computed).

Ecobilan a développé un logiciel d'évaluation des impacts sur l'environnement associé à différents types de traitement des déchets ménagers. L'outil permet de comparer différents scénarios de traitement des déchets, dont l'incinération, le recyclage, la mise en décharge. Une attention particulière a été consacrée à l'interface utilisateur, qui permet de se déplacer rapidement entre les différentes parties du logiciel. La construction du système et les calculs sont effectués automatiquement avec TEAMTM, le logiciel d'Ecobilan de calcul des analyses du cycle de vie. Des jeux de graphiques peuvent alors être tracés et permettre de représenter les flux comptabilisés (environ 150) et les impacts sur l'environnement disponibles dans l'outil (environ 20).

Abstract. The regional analysis of extreme hydrological events is connected with the availability of a dense network of rainfall data that is absent or inaccessible in Brazil, especially for sub-daily information. In engineering, extreme events rainfall information is represented by intensity–duration–frequency (IDF) relationships which are the most commonly used tools in water resources engineering for planning and design. Even if the sub-daily information that is included in the relationships is not available, the extreme rainfall information rest in the fundamentals of the IDF. This paper analyzes spatial distribution and track changes in sub-daily precipitation over Northeastern (NE) Brazil. Precipitation was estimated from IDF relationships information in Brazil based in rainfall measured from 1920's to 1950's (but still used in engineering projects) and information from the last half of the 20th century obtained from several IDFs gathered from municipalities' manuals, local symposia and books in many cases not easily obtainable. Results showed an intensification of extreme events in recent years, especially in shorter duration rainfall (less than 12 h). Hourly rainfall is bigger in almost all the Brazilian region, but especially in littoral and Northern portion, however, 12 and 24 h rainfall exhibit increases in the North, but, lower values in the Southern half of the region in concordance with flood changes reported by Milly et al. (2005). Analyzing the ratio between 1 and 24 h rainfall is possible to confirm its increase in all the region, with up to 35% in some areas. These results were able to show insight of sub-daily extreme events changes during 20th century in NE Brazil were previous reports were not found. The results also alerts for the necessity of engineering projects review, as outdated information is still being used for design purposes.

Both the scholarly and certainly the popular literatures surrounding information and computing ethics make frequent reference to one or more revolutions. To be sure, in an age that has witnessed—and is increasingly driven by—rapid technological innovation and diffusion, it is tempting to believe that new technologies cannot help but to transform our lives and worlds in radical, dramatic, and thus revolutionary ways.
Mellom samfunnsstrukturer og profesjon: om avgrensning, kultivering og premisser for adekvat skjønnsutøvelse i legerollen
Authors: Bærøe Kristine
Published: June 2015

Denne artikkelen tar utgangspunkt i et skille mellom samfunnsstrukturer som avgrenser legers skjønnsmessige utfoldelse på den ene siden, og profesjonens tilrettelegging for kultiveringen av erkjennelsesmessige ferdigheter på den annen. Ved å videreføre H. Grimen og A. Molanders anvendelse av S.E. Toulmins modell for praktisk resonnering i en klinisk kontekst redegjør jeg for legeskjønnets multidimensjonale, epistemiske struktur. Gjennomgangen viser hvordan skjønnsanvendelse i legerollen kan analyseres i henhold til en fagteknisk, en distributiv og en relasjonell dimensjon. Mot denne bakgrunnen diskuterer jeg så spenninger som oppstår i skjæringspunktet mellom strukturering og kultivering av skjønnets ulike dimensjoner. Diskusjonen tydeliggjør at den medisinske profesjonen ikke kan betraktes som en selvtilstrekkelig premissleverandør når det gjelder å sikre adekvat kultivering av medlemmenes skjønnsutøvelse i en klinisk kontekst. Ved å synliggjøre og vektlegge de relevante profesjonseksterne bidragene i profesjonens pågående selvregulering kan befolkningens berettigete tillit til profesjonen styrkes ytterligere.Nøkkelord: strukturelt skjønn, epistemisk skjønn, profesjon, selvregulering, tillitEnglish summary: In Between Structures of Society and Profession: On Delimitation, Cultivation and Premises for Adequately Exercising Judgment in the Role as PhysicianThe point of departure of this article is a distinction between societal structures that delimit the discretion of the physician on the one hand and the profession's arrangements for the cultivation of the physician's judgment on the other. By developing H. Grimen and A. Molander's application of S.E. Toulmin's model for practical reasoning in a clinical context, the multi-dimensional epistemic structure of the physician's judgment in terms of technical, distributive, and relational judgment is accounted for. Against this backdrop, tensions emerging in the intersection between delimitation and cultivation of professional judgment in its various dimensions are discussed. The discussion clarifies that the medical profession is not a self-sufficient provider when it comes to ensuring an adequate cultivation of its members' judgment in a clinical context. It is argued that by emphasising and implementing the relevant external contributions to the profession's ongoing self-regulation, the public's justified trust in the medical profession can be strengthened.
Why is integration so difficult? Shifting roles of ethics and three idioms for thinking about science, technology and society
Authors: Nydal Rune
Published: June 2015

Contemporary science and technology research are now expected to become more responsible through collaboration with social scientists and scholars from the humanities. This paper suggests a frame explaining why such current calls for ‘integration’ are seen as appropriate across sectors even though there are no shared understanding of how proper integration is to take place. The call for integration is understood as a response to shifting roles of ethics within research structures following shifts in modes of knowledge production. Integration is difficult, this paper suggests, because it challenges the modern normative division of labor affecting professional identities across sectors. Working out modes of integration is one important venue for working out alternative professional identities on the one hand and viable alternative understandings of research on the other hand. This paper discusses the matter with reference to three successive idioms for thinking about science, technology and society discussed in the literature; the representational, performative and co-production idiom.

Shear zone broadening controlled by thermal pressurization and poroelastic effects during model earthquakes
Authors: Chen J. , Rempel A. W.
Published: June 2015

As a result of the comminution that takes place over numerous earthquake cycles, mature faults are characterized by thick layers of pulverized gouge with finite porosity that is saturated with water at seismogenic depths. The heat generated during earthquakes raises the gouge temperature and thermal expansion of the pore fluid, and surrounding solids produce elevated pore pressures that cause fault strength to decrease in the process known as thermal pressurization. Building upon this framework, we describe a model that imposes a plane‐strain configuration and shows that the stress variations caused by porothermoelasticity promote the Mohr‐Coulomb failure of previously undeformed regions. Except in special cases where the friction is rate strengthening, we find that the frictional strength must vary throughout the post‐failure region, which we identify in our model with the shear zone. We introduce a strain rate function that describes the overall influence of distributed slip on energy dissipation and fault strength as the shear zone thickness expands. Using typical fault parameters at 7 km depth, the shear zone reaches several millimeters of thickness after 1 s sliding at an overall rate of 1 m/s. The expansion of the shear zone limits the temperature rise to several hundred degrees Celsius, and the average fault strength falls to about a tenth of the static frictional strength.

Herein we describe a total synthesis of the natural product heraclemycin B. This synthetic approach follows a Diels–Alder strategy to form the anthracenone core followed by a β‐ketosulfoxide and aldehyde annulation to form the 4‐pyranone D ring. The spectral data for the synthesized product matches that reported in the isolation studies.
Immobilization of cationic polyelectrolyte on polystyrene spheres and adsorption for model whitewater contaminants
Authors: Xiao He , He Beihai , Li Junrong
Published: June 2015

Polystyrene (PS) spheres with cationic polyelectrolyte brushes were prepared by reversible addition‐fragmentation chain transfer polymerization (RAFT) from cross‐linked PS spheres. These PS spheres were subsequently modified by reaction with chloroacetyl chloride and S,S‐Bis(α,α’‐dimethyl‐α”‐acetic acid) trithiocarbonate to serve as macro chain transfer agents (macro‐CTAs). Methacryloxyethyltrimethyl ammonium chloride (MAC) was then grafted from these macro‐CTAs of PS spheres to obtain cationic PS spheres. FT‐IR, 13C‐NMR, SEM, element analysis, and TGA techniques were applied to investigate and optimize the structure of PS spheres. The cationic PS spheres loading 1.35 mmol/g poly‐MAC were used as absorbents for removal of polygalacturonic acid (PGA) and sodium ligninsulfonate (lignin‐Na). Adsorption capacity of cationic PS spheres could reach 3 mg PGA/g and 24 mg lignin‐Na/g, respectively. Moreover, adsorption isotherm data of PGA were described by Langmuir‐Freundlich model, whereas lignin‐Na conformed to Langmuir model. Kinetic studies suggested that dissolved substances (PGA and lignin‐Na) could diffuse into the pores of cationic PS spheres. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 42509.
Large Eddy Simulation of Turbulent Reactive Mixing at High Schmidt and Reynolds Numbers
Authors: Walter Matthias , Kornev Nikolai , Hassel Egon
Published: June 2015

Large eddy simulation is used to investigate the reactive scalar transport in a confined jet reactor at high Reynolds and Schmidt numbers. Numerical simulations are performed for a fast neutralization reaction of acid and base supported by experimental data. Based on detailed planar laser‐induced fluorescence measurements, a simple conditional micromixing model for infinitely fast chemistry is developed and successfully applied to the jet mixer configuration. Results obtained for the reactive scalar transport are in excellent agreement with measurements, whereas established micromixing approaches based on the eddy dissipation model, multi environment model, and presumed probability density function with infinetly fast chemistry models indicate discrepancies in the determination of micromixing rate and product concentration.
