Authors: Netto Leonardo Dantas de Souza , Reis Taline Valéria Góes , Guimarães André Da Silva , Santana Pedro Leite de , Silva Antônio Santos , Pagano Rogério Luz
Published: May 2016

A pesquisa por novas alternativas e processos geradores de energia tornou-se fundamental para atender à demanda mundial por fontes energéticas sustentáveis e menos agressivas ao meio ambiente. Defronte destes fatos, a produção de hidrogênio converte-se numa alternativa viável, por ser considerado um combustível limpo e de alta densidade energética. A principal rota industrial para a obtenção de hidrogênio é a reforma a vapor do metano. Este é um processo endotérmico, no qual o metano reage com o vapor d’água, sob condições de elevadas temperaturas e pressão, para geração de hidrogênio. Recentemente, os avanços na área de modelagem e simulação, especialmente aplicando a técnica de fluidodinâmica computacional, vem auxiliando na investigação e otimização destes processos, sem que haja gastos relacionados à realização do mesmo. Diante deste contexto, o presente trabalho teve como finalidade simular um reator com membrana por meio de um software comercial, com a finalidade de realizar a otimização das suas condições operacionais. O Algoritmo Genético (AG) foi aplicado com o intuito de maximizar a produtividade do processo. Foram obtidos perfis simulados do reator para a conversão de metano e recuperação de hidrogênio alcançando valores de 100 %, o que comprova a eficácia da metodologia apresentada para otimizar as principais variáveis do processo.

Authors: Da Graça Denes Carlos Santos , Cardoso Gisélia , Cavalcante Erinaldo Hilário
Published: May 2016

Modificadores de ligantes asfálticos, tais como polímeros, borrachas de pneus moídos, borra oleosa de petróleo, dentre outros, vêm sendo estudados para melhor adequação destes às condições de uso. Contrariamente aos puros, os ligantes modificados apresentam comportamento reológico não-Newtoniano. Por essa razão, a dosagem de mistura asfáltica com ligantes modificados apresenta restrições às metodologias convencionais. Neste estudo, a modificação do ligante asfáltico CAP 50/70 foi realizada utilizando-se 10% e 20%, em massa, de masterbatch’s de borracha de pneus inservíveis com borra de petróleo, na proporção 15/85 (CM1) e 85/15 (CM2), seguindo a Norma DNER – ME 043/95. Os resultados mostraram que é possível dosar misturas asfálticas com o CAP 50/70 modificado com borra de petróleo seguindo-se a metodologia da referida Norma.
Modificação de celulose e avaliação da sua ação no fenômeno de parafinação em petróleo
Authors: Santos Clécio Martinho do Rosário , Da Graça Denes Carlos Santos , Cardoso Gisélia
Published: May 2016

A celulose é uma substância natural, macromolecular, não tóxica, de origem renovável e biodegradável, cuja estrutura química pode sofrer modificações através da substituição das hidroxilas presentes na sua macromolécula e assim, obter produtos com variadas propriedades de uso. Com o aumento da atenção mundial para a degradação ambiental, a obtenção de novos produtos a partir de modificação química da celulose tem sido realizada com crescente aplicabilidade em diversos setores industriais, dentre eles, a indústria de extração e produção de petróleo. Este estudo mostra a ação de uma substância surfactante obtida a partir de xantatos celulósicos de sisal (Agave sisalana) modificado em bancada de laboratório com álcool láurico no fenômeno de parafinação de petróleo pesado, por meio da medida de temperatura de iniciação de aparecimento de cristais de parafina (TIAC) e da energia de ativação de fluxo. Os resultados dos referidos experimentos mostraram que este não reduziu os valores de TIAC em amostra de óleo pesado em estudo, mas promoveu reduções na energia de ativação de fluxo.
Wilson’s type Hilbert space valued functional equations

Published: May 2016

In the present paper we characterize, in terms of characters, additive functions and matrix elements of irreducible two-dimensional representations, the continuous solutions of some trigonometric functional equations for mappings defined on an arbitrary group and taking their values in a complex Hilbert space with the Hadamard product. In addition, we investigate a superstability result for these equations.
Number of Firms, Rationing, Matching, and Knowledge: A Comprehensive Study of Variations in Experimental Kreps–Scheinkman Markets
Authors: Jacobs Martin
Published: May 2016

This study provides a comprehensive picture of experimental Kreps–Scheinkman markets with capacity choice in the first stage and subsequent price competition in the second. We conduct seven different treatments of such markets, varying the number of firms, demand rationing, subject matching, and subjects’ knowledge about the market mechanism. We find that only the number of firms has a persistent effect on capacity choices, whereas price choices are affected by both the number of firms and the rationing scheme. From the outset, subjects in the high-knowledge condition behave in the same way as subjects with low knowledge do in later periods after gaining experience. In all treatments, conduct is more competitive than the Cournot outcome, irrespective of the Nash equilibrium prediction. Nevertheless, the Cournot model does pack some predictive power. Under efficient demand rationing where the Cournot outcome is predicted, exact Cournot choices are more likely for both capacities and prices.

Authors: Mžik Martin , Chmelařová Marcela , John Stanislav , Laco Jan , Slabý Ondřej , Kiss Igor , Bohovicová Lucia , Palička Vladimír , Nekvindová Jana
Published: May 2016

Background:

Aberrant hypermethylation of tumour suppressor genes (TSGs) occurring in hepatocellular carcinoma (HCC) could provide a mean of molecular characterisation of this cancer. The aim of this study was to investigate promoter methylation and gene expression of selected TSGs in HCC to identify candidate genes for further validation as potential biomarkers.

Methods:

Methylation-specific multiplex ligation-dependent probe amplification method was used to measure the methylation status of 25 TSGs in 49 HCC samples and 36 corresponding non-cancerous liver tissue samples. Relative expression of the differentially methylated genes was assessed at the mRNA level using quantitative PCR.

Results:

We observed a significantly higher methylation in genes WT1, PAX5, PAX6, PYCARD and GATA5 in HCC compared with control samples. The expression of PAX5 was significantly decreased by methylation; conversely methylation of WT1 was associated with higher mRNA levels. Methylation of GATA5 was significantly associated with overall survival and methylation of WT1 and PAX5 significantly varied between patients with ALBI score 1 vs. 2+3. Moreover, PAX5 was significantly more methylated in patients with tumour grade 2+3 vs. grade 1, and methylation of the PAX5 correlated with the patient’s age at the time of diagnosis.

Conclusions:

HCC evince aberrant promoter methylation of WT1, PAX5, PAX6, PYCARD and GATA5 genes. Correlation between GATA5, WT1 and PAX5 methylation and clinical/histological parameters is suggestive of applicability of these markers in non-invasive (epi)genetic testing in HCC.
HbA1c: EQA in Germany, Belgium and the Netherlands using fresh whole blood samples with target values assigned with the IFCC reference system
Authors: Kaiser Patricia , Spannagl Michael , van Campenhout Christel , Lenga Yolande , Siebelder Carla , Weykamp Cas
Published: May 2016

Background:

External quality assessment/proficiency test (EQA/PT) organizers play an important role in monitoring the performance of HbA1c measurements. With increasing quality of the assays, HbA1c is increasingly used for diagnosis of diabetes and the demands on EQA/PT organizers themselves are rising constantly. EQA organizers in Germany (INSTAND), Belgium (WIV/IPV), and the Netherlands (SKML) organized a program with commutable samples and target values assigned with the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) reference system. The aim of this project was to confirm the logistic feasibility of organizing synchronically in the three countries, an accuracy-based EQA program with fresh whole blood, to investigate the performance of HbA1c assays within and across countries and manufacturers, and to review the EQA acceptance limits.

Methods:

Throughout 2015, ten fresh whole blood samples were supplied to the participants. Aggregated results were evaluated according to the IFCC model for quality targets at four levels: overall, per country, per manufacturer, and per country per manufacturer.

Results:

Robust results in summer and winter demonstrated the feasibility of organizing an EQA with fresh whole blood samples in three countries. The overall performances, as well as the performance for each country were very similar: results fell within the IFCC criteria. Although substantial differences between results from different manufacturers were present, the performances of laboratories using tests of the same manufacturer were strikingly similar in the three countries, suggesting that the quality of HbA1c assays is for the most part manufacturer- related. The improved design of the EQA program also suggested that acceptance limits for performance can be reduced to approximately 8%.
Inward and Outward Foreign Direct Investment and Inequality: Evidence from a Group of Middle-Income Countries
Authors: Huang Chao-Hsi , Teng Kai-Fang , Tsai Pan-Long
Published: May 2016

Using panel data of a group of 39 middle-income countries over 1981–2006, this paper examines how globalization in general and inward and outward FDI in particular affects inequality. Depending on geographical region and economic system, each component of globalization affects inequality in three groups of countries in different ways: open to inward FDI tends to affect income distribution adversely in transition economies and Latin American countries, but marginally improves income distribution in countries of the reference group. In contrast, open to outward FDI is positively associated with inequality in the reference group whereas negatively associated with that of the other two groups of countries. Crucially, improvement in human capital appears to be the single most reliable way to reduce inequality.

Authors: Koteswara Reddy Chagam , Kimi Lalmuan , Haripriya Sundaramoorthy
Published: May 2016

Starches isolated from three different pigmented rice varieties (Chak-hao Amubi, Chak-hao Poireiton, and Chak-hao Angangba) and investigated for their molecular structure and physico-chemical properties including amylose content, morphology, crystallinity, pasting viscosity, color, thermal property, swelling power and solubility. Significant differences were detected in physico-chemical and functional properties (p
≤0.05) of rice starches. The amylose content results revealed that Chak-hao Angangba (1.93 %) and Chak-hao Poireiton (1.98 %) are waxy rice, and Chak-hao Amubi (3.16 %) is a very low-amylose rice. The morphology of rice starch granules shown polyhedral edges with an irregular shape; and the XRD patterns of rice starches exhibited A-type crystalline patterns with peaks at 2θ=15.1°, 17.1°, 18.2° and 23.0°. Waxy rice starches shown higher peak viscosity and enthalpy with lower gelatinization temperatures than very low amylose rice starches. The pasting viscosity, swelling power and solubility crystallinity of rice starches were varied significantly (p
≤0.05). Finally, the present study provides knowledge for the utilization of starches isolated from three pigmented rice varieties grown in North-Eastern part of India that would be relevant for both domestic and industrial applications.
African diaspora and the circulation of language: Cuban and Afro-Cuban loanwords in Equatorial Guinea
Authors: Castillo-Rodríguez Susana
Published: May 2016

When in 1861 nearly 200 emancipated black Cubans settled in the “Barrio Congo” of Fernando Po to work in public construction, a process of language contact initiated. Four years later, a few hundred political activists were deported from Cuba to Fernando Po because of their potential influence in the Cuban revolution. This historical episode might have triggered Cubans’ and Afro-Cubans’ lexical transfers to the Spanish spoken in Fernando Po as a result of the two-way connection of the transatlantic slave trade. Based on royal decrees, archival material and the memoirs of Cuban exiles (Balmaseda, Francisco Javier. [1869] 1874.

Knowledge of health principles among professionals in Slovenian kindergartens
Authors: Slabe Damjan , Fink Rok , Dolenc Eva , Kvas Andreja
Published: May 2016

Objectives

Preschool children have significant health issues. From the relevant legislation and regulations, it can be seen that kindergarten teachers (KTs) and kindergarten teacher assistants (KTAs) are expected to be familiarwith the basic hygienic measures and steps for preventing injuries and illnesses, to recognize infectious diseases, and to know how to give the first aid. To gain these skills, a continuous life-long learning is necessary, because the characteristics of diseases are changing. Study design: original research.

Methods

45 kindergartens in Slovenia were randomly selected and a questionnaire with 17 questions on health themes was sent. An analysis was performed via SPSS 17.0, using descriptive methods and nonparametric χ2 tests.

Results

There were 774 participants, of whom 56% were KTs and 44% KTAs. The share of KTs and KTAs who consider their knowledge of health principles to be very good or excellent is 67%. Their estimation of first aid knowledge is lower. They are also well aware of the importance of health knowledge in their work; a total of 87% strongly agree with this. The results also show that they are familiar with hygiene principles. The χ2 test showed there are certain statistically characteristic connections between the age of teachers and their assistants, occupation and work experiences.

Conclusions

Because children are a particularly vulnerable group, teachers can encounter injuries and sudden illnesses at their work. Supplementary education is necessary among skilled workers in educational institutions, including kindergartens.

Authors: Gallucci Gerardo , Calderón Warner Larrondo , Boretto Jorge , Castellaro Lantermo Juan Antonio , Terán Julio , De Carli Pablo
Published: May 2016

Objetivo

Reportar los resultados clínico-radiológicos del tratamiento de las fracturas del húmero distal (FHD) con prótesis total de codo en pacientes > 65 años.

Material y métodos

Este trabajo retrospectivo fue realizado en 2 centros quirúrgicos. Se incluyeron: pacientes con FHD, > 65 años, operados con prótesis total de Coonrad-Morrey y con seguimiento >1 año. Se incluyeron 21 pacientes. Veinte eran mujeres con una edad promedio de 79 años. Según la clasificación AO, 13 fracturas eran del tipo C3, 7 C2 y una A2. Todos los pacientes fueron operados sin desinserción del aparato extensor. El seguimiento promedio fue de 40 meses.

Resultados

La flexo-extensión fue de 123-17°, con un arco de movilidad de 106° (un 80 % con respecto al lado sano).  El dolor según EVA fue de 1 punto. El SCM promedio fue de 83 puntos: 8 pacientes tuvieron resultados excelentes, 11 buenos, 1 regular y 1 malo. El DASH promedio fue de 24 puntos. No se evidenciaron aflojamientos en 13 pacientes. Se observaron 9 complicaciones: 2 pacientes fueron reoperados por desgaste del polietileno, 1 paciente fue reoperado al mes de la cirugía para la recolocación del perno de ensamble por una falla en la colocación del mismo, 2 pacientes presentaron parestesias postoperatoria del nervio cubital. Un paciente presentó un hematoma de la herida que produjo una necrosis de la piel y necesitó de un colgajo braquial para su cobertura.

Conclusiones

El tratamiento de FHD con prótesis total de codo en pacientes  > 65 años, puede ofrecer una opción razonable de tratamiento, pero las indicaciones deben estar limitadas a fracturas complejas donde la fijación interna puede ser precaria, en pacientes con osteoporosis y con baja demanda funcional.
Diferencias en las habilidades emprendedoras desde la categoría género en los y las estudiantes de la Facultad de Ingeniería, sede Bogotá
Authors: Becerra Arias Luis Abraham
Published: May 2016

Resumen. Este artículo es producto de la investigación “Estudio de perfil del emprendedor de la Universidad Cooperativa de Colombia, sede Bogotá”. El grupo de investigación Induspymes analizó durante el 2012 la percepción de desarrollo de habilidades para el emprendimiento de los miembros de la comunidad académica y estudiantil de la Facultad de Ingeniería, sede Bogotá, desde la categoría género. La muestra comprendió 502 miembros de la comunidad académica (docentes y estudiantes) de la Facultad. Se diseñó una encuesta y los datos se analizaron con un nivel de significancia del 0,01, 4 grados de libertad y un factor crítico de 13,27. Entre los hallazgos más relevantes están las diferencias en el desarrollo de habilidades de emprendimiento entre hombres y mujeres asociadas con la tendencia de asumir riesgos y el manejo de la frustración, para el caso de los hombres; sin embargo, las mujeres presentan mejor desempeño en la capacidad comercial y la autoestima. Es de anotar que los resultados anteriores deben ser revisados y ampliados a partir de aspectos fundamentales que deben estudiarse en el futuro, en especial los relacionados con las diferencias de género y el deseo de establecer una empresa (los motivos y obstáculos que encuentran mujeres y hombres para realizar un emprendimiento). Esto permitirá aportar nuevas perspectivas para la construcción, validación y gestión del modelo institucional.
Ghanaian Screendance Perspectives: The Nuance of ‘Sankofaism’ as Emerging Aesthetics and Rejection of Orthodoxy
Authors: Benagr Samuel , Ofosu Terry B.K.
Published: May 2016

Screendance is a hybrid art in which choreographic and film techniques are necessary for creating texts where the body dialogues with camera. Ghanaian dance film is best understood within the context of postmodern discourse. This article argues that indigenous and foreign cultural practices are convoluted by morality and hegemonic influence of western culture. Moving from orthodoxy, the Ghanaian dance film re-contextualizes dance practice and film techniques into a composite construct with a tinge of Afrocentrism. Framed by *critical sankofaism*, screendances in Ghana are discussed as being influenced by individual musician's ideas with western biases. Dances for television are shaped by institutional guidelines gleaned from Ghanaian culture. Using *Heyba* and screendance at TV3 Network and GTV, this article discusses dance films as an emerging aesthetic that re-interprets the function of bodies, their relationships with the camera, and concludes that more than being a hybrid site, screendance in Ghana is a 'polybrid'.

Medicine and the Art of Seeing
Authors: Rosetti Leah Natalie
Published: May 2016

This Humanities in Medicine article is an examination of the use of formal fine arts training in medical curricula to enhance diagnos­tic skills. A great amount can be discerned about pathology and pathophysiology using visual cues. Conventional medical education stresses the importance of physical diagnostic skills but often omits explicit teaching on how to methodically observe for information that could be useful for diagnosis. The current curriculum could be greatly complimented by the study of fine arts, which deals directly with the careful observation, description, and interpretation of the visual world. Cet article sur la médecine et les humanités est un aperçu sur la pertinence d’incorporer une formation formelle des beaux-arts dans le curriculum médical afin d’optimiser l’habileté des cliniciens à poser un bon diagnostic. L’utilisation de repères visuels est d’une grande utilité pour discerner la pathologie et la physiopathologie de différentes maladies. L’éducation médicale conventionnelle souligne l’importance de l’examen physique lorsqu’on doit poser un diagnostic, mais néglige parfois l’enseignement d’une approche méthodique qui utilise activement l’observation afin de repérer des informations qui pourraient être très utiles dans le diagnostic d’un patient. Le curriculum actuel pourrait très bien incorporer l’étude des beaux-arts, car celle-ci implique une observation, une descrip­tion et une interprétation du monde visuel qui nous entoure.
Isolation and antioxidant activity of flavonoids from Holarrhena floribunda (G.don) leaves.
Authors: Badmus Jelili A , Ekpo Okobi E , Rautenbach Fanie , Marnewick Jeanine L , Hussein Ahmed A , Hiss Donavon C
Published: May 2016

Bioactive polyphenolics are ubiquitously present in plants and may play an important role in the prevention and management of certain human diseases. Three known flavonoids viz Kaemperol-3-O-rutinoside (1), quercetin-3-O-glucoside (2) and kaemperol-3-O-glucoside (3) and inseparable mixture (1:1) of quercetin-3-O-glucose/galactose (4) were isolated, and identified for the first time from Holarrhena floribunda. The antioxidant capacity using the ORAC, FRAP and TEAC assays and inhibition of lipid peroxidation were measured for isolated flavonoids. The result showed that compounds 2 and 4 showed significantly increased ORAC, TEAC, and FRAP activities with low pro-oxidant potential as well as improved lipid peroxidation inhibition levels when compared to compounds 1 and 3. The most active compounds were found to be flavonoids with a quercetin basic structure. These results imply that the isolated flavonoid glycosides are responsible for the antioxidant activity of the plant leaves and it forms the scientific basis for its traditional usage.

Brenneria nigrifluens y Brenneria rubrifaciens, causan el cancro superficial y profundo de la corteza del nogal, respectivamente. B. nigrifluen ocasiona necrosis en la corteza exterior y manchas dispersas de exudado marrón oscuro. Los síntomas de B. nigrifluens involucra hoyos en la madera, grietas profundas longitudinales en el tronco, exudado color oscuro marrón con bacterias que fluyen de las grietas de las ramas. Finalmente, las dos enfermedades pueden ocasionar pérdida de vigor y muerte de los árboles. El cancro del nogal ocasionado por especies de Brenneria se ha reportado principalmente en Estados Unidos, Francia, España, Italia, Hungría, Persia e Irán. En México no se han reportado, sin embargo, SENASICA (Servicio Nacional de Sanidad, Inocuidad y Calidad Agroalimentaria) ha establecido mapas de riesgo, ya que en México el nogal pecanero es un cultivo rentable, para el año 2014, se tuvo una producción de 125 758 ton, con un valor mayor a 6 173 millones de pesos. Debido a la patogenicidad de las bacterias, el diagnóstico oportuno es clave en el manejo de la enfermedad. Los principales métodos de diagnóstico del género Brenneria spp son: observación de signos y síntomas, pruebas bioquímicas como el sistema API, Biolog y el análisis de los ácidos grasos celulares; técnicas serológicas; técnicas moleculares como PCR punto final y tiempo real; así como técnicas cromatográficas (HPLC, CCD) para detección de metabolitos específicos como la rubrifacina. El trabajo tiene como objetivo presentar la situación a nivel nacional y mundial del cancro del nogal, así como revisión de las técnicas de diagnóstico de la enfermedad.

Late Partial Dissociation of a Humeral Head Morse Taper Associated with Periprosthetic Proximal Humeral Fracture
Authors: Lee Alan H. , Dilisio Matthew F. , Warner Jon J.P.
Published: May 2016

Case:

A fifty-two-year-old man who had undergone total shoulder arthroplasty ten years previously presented following a mechanical fall onto his operatively treated shoulder, resulting in a periprosthetic humeral fracture and partial dissociation of the humeral head from the stem.

Conclusion:

Shoulder surgeons should consider late disengagement of the Morse taper as a potential cause of surgical failure. Partial late dissociation of the humeral head from the stem after shoulder arthroplasty is possible and can be associated with a fracture. The shoulder surgeon should be aware of this potential complication when evaluating periprosthetic proximal humeral fractures, emphasizing the importance of attention to detail when evaluating patients.

Ozone- A Biological Therapy in Dentistry- Reality or Myth?????
Authors: Naik Saraswathi V. , K Rajeshwari , Kohli Shivani , Zohabhasan Sayyad , Bhatia Shekhar
Published: May 2016

The usage of ozone in dentistry has been proposed because of its antimicrobial, disinfectant, biocompatibility and healing properties. In the last decade a number of therapeutic protocols with ozone have been developed to address common dental infections associated with periodontal disease, RCT and caries. Despite these advantages, therapeutic ozone’s application in dentistry is limited because of its possible side effects. Hence, dental practitioners need to know the proper usage of ozone therapy that can provide better patient care and considerably cut down the time and cost of the treatment.
Geographic maps as evidence in practice of the international court of justice
Authors: Novakovic Marko
Published: May 2016

The paper deals with the use of geographic maps as evidence in the practice
of the International Court of Justice with a view to the latest cases in
which the Court in its judgments elaborated maps as evidence: the case
Certain Activities carried out by Nicaragua in the Border Area (Costa Rica v.
Nicaragua) and Construction of a Road in Costa Rica along the San Juan River
(Nicaragua v. Costa Rica). The analysis comprehends the evidentiary value of
geographic maps throughout the International Court of Justice's jurisprudence
and even in the case-law of its predecessors. The author emphasizes that the
substantial element that affects whether a geographic map will be accepted as
direct evidence before the International Court of Justice is the consent of
the parties to the dispute, as well as the fact, that the map stands as an
expression of the will of the state. The author concludes that the map
properties-such as details, quality and consistency-have no impact on the
acceptance of the map as direct evidence, but only on whether the geographic
map is to be accepted as an indirect proof.
Evaluation of the natural radioactivity level of Nigerian tar sand deposits, eastern Dahomey basin, southwestern Nigeria

The specific activities of natural radionuclides in twenty seven samples
collected from the eastern Dahomey basin in southwestern Nigeria were
evaluated. Experimental results were obtained by using a 3" x 3" sodium
iodide NaI(Tl) detector. A major trace element assessment of the samples was
made by Inductively Coupled Plasma Mass Spectrometry techniques. Gamma ray
radioactive standard sources, 137Cs and 60Co, were used to calibrate the
measurement system and the International Atomic Energy Agency SOIL-375
radioactive standard source was also used to analyze and compute the specific
activities of desired natural radionuclides. Three radioelements, viz. 238U,
232Th and 40K, were identified in the samples with the following specific
activities of 238U ranging from 9.88 ? 4.70 Bq/kg to 69.15 ? 12.37 Bq/kg with
an average of 26.50 ? 7.18 Bq/kg; 232Th from 12.78 ? 5.16 Bq/kg to 36.86 ?
13.35 Bq/kg with an average of 22.77 ? 4.28 Bq/kg; 40K ranging from 189.82 ?
79.51 Bq/kg to 518.77 ? ? 119.54 Bq/kg with an average of 297.69 ? 16.21
Bq/kg. The result was compared with the world mean values of 35, 30 and 400
Bq/kg, respectively, specified by the United Nations Scientific Committee on
the Effects of Atomic Radiation. The mean result obtained for the radium
equivalent, total absorbed dose rate, external hazard index, internal hazard
index, and the annual effective dose equivalent, were 79.90 Bq/kg, 38.50
?Sv/h, 0.22 Bq/kg, 0.29 Bq/kg, and 47.22 ?Sv, respectively. With respect to
radiological risk to human health, the absorbed gamma dose rate in air was
estimated to be in the range of 21.7 ? 0.4 to 155.7 ? 2.2 ?Sv/h; the outdoor
annual effective dose equivalent was evaluated to vary from 26.6 ? 0.4 to
190.9 ? ? 2.7 ?Sv with the arithmetic mean value of 79.06 ? 33.23 ?Sv and
compared to the world-wide effective dose of 70 ?Sv. Also, the values of the
radium equivalent and the external hazard index for all samples in the study
area were found to be lower than the accepted safety limit value of 370 Bq/kg
and equally below the limit of unity, respectively. The results indicate
that, at present, the radiation hazard from radionuclides in all samples
analyzed is within permissible limits.
New head process for non-HEU 99Mo production based on the oxidation of irradiated UO2-pellets forming soluble U3O8
Authors: Beyer Gerd , Eichler Bernd , Reetz Teja , Muenze Rudolf , Comor Jozef
Published: May 2016

All fission-based 99Mo producers worldwide are required to convert their 99Mo
production processes from using highly enriched uranium to low-enriched
uranium. At a recent IAEA meeting in Vienna, problems related to bottlenecks
and target modification and optimization of low-enriched uranium-based 99Mo
production processes were discussed. Ceramic UO2-pellets (as used in fuel)
were excluded from the discussion with the argument that this material cannot
be dissolved under practically applicable conditions. In this paper, we
suggest transforming the non-soluble ceramic UO2 fuel-pellets into the U3O8
form by simple oxidation and the use of the soluble U-oxide modification as
the starting material for the 99Mo production processes. Due to the absence
of Al, larger target quantities could be processed and the waste volume could
still be kept small. The approach is known and proven in nuclear technology.
In principle, this new head process can be connected to any of the presently
used 99Mo production procedures.
Steady-state heat conduction in a medium with spatial non-singular fading memory: Derivation of Caputo-Fabrizio space-fractional derivative from Cattaneo concept with Jeffrey`s Kernel and analytical solutions
Authors: Hristov Jordan
Published: May 2016

Starting from the Cattaneo constitutive relation with a Jeffrey's kernel the derivation of a transient heat diffusion equation with relaxation term expressed through the Caputo-Fabrizio time fractional derivative has been developed. This approach allows seeing the physical back ground of the newly defined Caputo-Fabrizio time fractional derivative and demonstrates how other constitutive equations could be modified with non-singular fading memories.
Incidence of malignancy and outcomes for dogs undergoing splenectomy for incidentally detected nonruptured splenic nodules or masses: 105 cases (2009–2013)
Authors: Cleveland Matthew J. , Casale Sue
Published: May 2016

OBJECTIVE To determine the frequency of malignancy and survival rates of dogs that underwent splenectomy for incidentally detected nonruptured splenic masses or nodules.

DESIGN Retrospective case series.

ANIMALS 105 client-owned dogs.

PROCEDURES Medical records of dogs that underwent splenectomy at a veterinary teaching hospital between 2009 and 2013 were examined to identify patients with incidentally detected nonruptured splenic masses or nodules without associated hemoperitoneum. Only dogs with histologically confirmed diagnoses were included. Information regarding signalment, preoperative diagnostic tests, perioperative blood product transfusions, splenic mass diameter, histologic findings, adjunctive treatments, and survival time was collected and analyzed.

RESULTS 74 of 105 (70.5%) patients had benign splenic lesions and 31 (29.5%) had malignant neoplasia, most commonly hemangiosarcoma (18/31 [58%]). The hazard of death decreased as preoperative PCV increased; histopathologic diagnosis of malignant neoplasia was significantly associated with an increased hazard of death. Median life expectancy of dogs with benign and malignant lesions was 436 and 110 days, respectively; 41 of 74 patients with benign lesions and 3 of 31 patients with malignant neoplasia were still alive at study conclusion. Median life expectancy of dogs with hemangiosarcoma was 132 days; only 7 of these 18 dogs received any adjunctive chemotherapeutic treatments.

CONCLUSIONS AND CLINICAL RELEVANCE Incidentally found, nonruptured splenic masses or nodules without associated hemoperitoneum were most commonly benign. Results suggested that life expectancy for these dogs with incidentally detected benign or malignant splenic lesions that received prompt intervention was better than has previously been reported for other studied populations.

Published: May 2016

OBJECTIVE To evaluate efficacy and duration of immunity of the bovine herpesvirus type 1 (BHV-1) fraction of a trivalent vaccine also containing parainfluenza virus-3 and bovine respiratory syncytial virus fractions administered intranasally (IN) for protection of calves against infectious bovine rhinotracheitis (IBR).

DESIGN Controlled challenge study.

ANIMALS 120 dairy calves (3 to 8 days old) seronegative for antibody against BHV-1 (experiments 1 and 2) or seropositive for maternally derived antibody against BHV-1 (experiment 3).

PROCEDURES In 3 separate experiments, calves were vaccinated IN via 2 nostrils (experiment 1) or 1 nostril (experiments 2 and 3) with a vaccine containing or not containing a BHV-1 fraction. For seronegative calves, the test vaccine contained a minimum immunizing dose of BHV-1; for seropositive calves, it contained a commercial dose of BHV-1. Calves were challenged IN with virulent BHV-1 on day 28 or 193 (seronegative calves) or day 105 (seropositive calves) after vaccination to evaluate vaccine efficacy. Frequency and duration of clinical signs, rectal temperatures, virus shedding, and serologic responses were compared between treatment groups within experiments.

RESULTS In all experiments, BHV-1 vaccinated calves had lower frequencies or shorter durations of clinical signs of IBR than did control calves. Following viral challenge, peak rectal temperatures and degrees of virus shedding were lower and serologic responses were higher in vaccinated versus control calves.

CONCLUSIONS AND CLINICAL RELEVANCE IN vaccination against BHV-1 protected all calves against clinical IBR disease, regardless of serologic status at the time of vaccination, and suppressed virus shedding. A single dose of this IN vaccine has the potential to protect seronegative calves for at least 193 days and override maternally derived antibody to protect seropositive calves for at least 105 days.
Imported chikungunya cases in an area newly colonised by Aedes albopictus: mathematical assessment of the best public health strategy

Published: May 2016

We aimed to identify the optimal strategy that should be used by public health authorities against transmission of chikungunya virus in mainland France. The theoretical model we developed, which mimics the current surveillance system, predicted that without vector control (VC), the probability of local transmission after introduction of viraemic patients was around 2%, and the number of autochthonous cases between five and 15 persons per hectare, depending on the number of imported cases. Compared with this baseline, we considered different strategies (VC after clinical suspicion of a case or after laboratory confirmation, for imported or autochthonous cases): Awaiting laboratory confirmation for suspected imported cases to implement VC had no significant impact on the epidemiological outcomes analysed, mainly because of the delay before entering into the surveillance system. However, waiting for laboratory confirmation of autochthonous cases before implementing VC resulted in more frequent outbreaks. After analysing the economic cost of such strategies, our study suggested implementing VC immediately after the notification of a suspected autochthonous case as the most efficient strategy in settings where local transmission has been proven. Nevertheless, we identified that decreasing reporting time for imported cases should remain a priority.
