SIMULATION ANALYSIS OF PREHEATER CHARGE TO THE ROTARY FURNACE
Authors: Mikula Jan , Palička Pavol , Kerekanic Jan
Published: September 2015

Mathematical modeling of heat aggregates is one of the fundamental methods of the mathematical modelling research. A mathematical model based on the method of elementary balances was created for the thermal treatment of granular and lumpy materials. The adaptation of the selected aggregate model is based on prior knowledge and experiments. The paper presents an adaptation of the mathematical model for the magnesite processing rotary furnace using the mode of caustic and clinker production. A simulation of the charge preheater impact based on the thin layer principle is implemented into the model. The main advantages of using this type of preheater of rotary furnace are smaller dimensions for a large exchange surface and low pressure losses.
CFD SIMULATION OF THE HEAT TRANSFER PROCESS IN A CHEVRON PLATE HEAT EXCHANGER USING THE SST TURBULENCE MODEL
Authors: Skočilas Jan , Palaziuk Ievgen
Published: September 2015

This paper deals with a computational fluid dynamics (CFD) simulation of the heat transfer process during turbulent hot water flow between two chevron plates in a plate heat exchanger. A three-dimensional model with the simplified geometry of two cross-corrugated channels provided by chevron plates, taking into account the inlet and outlet ports, has been designed for the numerical study. The numerical model was based on the shear-stress transport (SST) k-! model. The basic characteristics of the heat exchanger, as values of heat transfer coefficient and pressure drop, have been investigated. A comparative analysis of analytical calculation results, based on experimental data obtained from literature, and of the results obtained by numerical simulation, has been carried out. The coefficients and the exponents in the design equations for the considered plates have been arranged by using simulation results. The influence on the main flow parameters of the corrugation inclination angle relative to the flow direction has been taken into account. An analysis of the temperature distribution across the plates has been carried out, and it has shown the presence of zones with higher heat losses and low fluid flow intensity.
NOx EMISSIONS FROM BUBBLING FLUIDIZED BED COMBUSTION OF LIGNITE COAL
Authors: Skopec Pavel , Hrdlička Jan , Opatřil Jan , Štefanica Jiří
Published: September 2015

This paper presents experimental results of NOx emission measurements for combustion of two kinds of coal in a bubbling fluidized bed combustor. The tested fuels were Czech brown coal (CBC) and German young brown coal (GYC). These fuels have different nitrogen contents. The experiments were performed in the pilot scale BFB experimental unit with power output of 500 kW. The influence of several parameters on NOx formation are investigated in this paper. The parameters studied here include the effect of the nitrogen content in the fuel, the effect of the oxygen concentration in the bed, the effect of bed temperature, the effect of air staging, and the effect of fluidization velocity. Significantly different behaviour of the fuels was found. Although GYC has a lower nitrogen content than CBC, it is more reactive and produces higher NOx emissions. The biggest dependence of NOx production for CBC was found for the effects of air staging and fluidization velocity. As the fluidization velocity increases and the amount of secondary air decreases, there is an increase in NOx emissions. The oxygen concentration in the bed has the strongest effect on the NOx production of GYCs. With increasing oxygen concentration, the production of NOx also increases. On the basis of the NOx measurements, the N-NO conversion factor was calculated and the effect of the operating parameters on this conversion factor was investigated.
The remote area nurse model of consultation
Authors: Lenthall Sue , Knight Sabina , Foxley Sally , Gordon Vicki , Ivanhoe Terrie , Aitken Robyn
Published: September 2015

Registered nurses working in remote areas of Australia are often called remote area nurses (RANs). RANs have traditionally used models of client consultation designed for acute presentations and episodes of care. However, presentations to health care facilities in remote Australia are more likely to be chronic, complex, multi-system and multifactorial in origin and subsequent management. This paper describes a consultation model developed from a combination of expert opinion, literature and trial and feedback from RANs. The model is comprehensive, systematic and puts the person at the centre of care. It aims to mitigate risk for the client; the RAN and the health service while at the same time building trust and health literacy between the client and the RAN to encourage the client to continue with the partnership in care.

Energy and our future: a perspective from the Clemson Nanomaterials Center
Authors: Rao Apparao M.
Published: September 2015

Our increasing energy demands have spurred a rigorous search for renewable energy sources to reduce our dependence on fossil fuels. However, efficient use of renewable energy is possible only with advances in both energy generation and storage. Today’s batteries and capacitors, which are the main energy storage devices, cannot meet the world’s demand for combined power and energy densities. To enhance the viability of such energy storing devices, the Clemson Nanomaterials Center (CNC) has developed a mix of scalable processes for carbon nanotube-based hybrid electrodes that show promise as a cost-effective alternative to standard activated carbon-based electrodes. Working together with industrial partners, CNC has fabricated supercapacitors with energy and power densities in the range of ~11–35 Wh/kg and ~1.2–9 W/kg, respectively. Although this research development is transformative, further studies to optimize the separator and electrolyte technologies are needed to maximize both the energy and power density in a single device.
Effects of the pre-irradiation storage procedure on the dose response of a Fricke xylenol orange gel dosimeter
Authors: Liosi Giulia Maria , Giacobbo Francesca , Pignoli Emanuele , Carrara Mauro , Gambarini Grazia , Mariani Mario
Published: September 2015

The Fricke xylenol orange (FX) gel system is a chemical dosimeter characterized by good sensitivity, linear dose response, tissue equivalence, no toxicity, easy preparation, reproducibility and low cost. Thanks to the presence of the gelatinous matrix, the system is particularly suitable to perform reliable 3D mapping of the absorbed dose spatial distribution via magnetic resonance imaging (MRI) or optical techniques. The aim of this work is to study in a systematic way the influence of the pre-irradiation storage procedure upon sensitivity, dose response stability and lifetime of use of a FX gel system made with gelatin from porcine skin subjected to homogeneous irradiation. For this purpose, different pre-irradiation storage procedures, in terms of temperature and duration of each storage step, were investigated. In order to evaluate the dose response stability, the optical analyses of the samples were performed up to 6 hours after irradiation. Moreover, the samples were irradiated at time intervals of 24 hours for up to 7 days after preparation in order to evaluate the system lifetime of use. Regardless of their thermal and temporal life, the samples show linear dose responses in the investigated dose range (3-24 Gy) and an increase of sensitivity with the time elapsed between preparation and irradiation. Among the three pre-irradiation storage procedures considered here, a procedure that provides the best dose response stability and lifetime of use was identified and recommended for further use. The analyzed dosimetric system possesses good properties that make it promising for medical application, particularly concerning the evaluation of pre-treatment plan quality assurance within the conformational external beam radiotherapy

Authors: Liu Wei , Liu Yafeng , Yuan Shujuan
Published: September 2015

In this article, the Bargmann system related to the spectral problem (∂2+q∂+∂q+r)φ=λφ+λφxis discussed. By the Euler–Lagrange equations and the Legendre transformations, a suitable Jacobi–Ostrogradsky coordinate system is obtained. So the Lax pairs of the aforementioned spectral problem are nonlinearised. A new kind of finite-dimensional Hamilton system is generated. Moreover, the involutive solutions of the evolution equations for the infinite-dimensional soliton system are derived.
Vaccine potential of a nonflagellated, virulence-plasmid-cured (fliD–, pSEVΔ) mutant of Salmonella Enteritidis for chickens
Authors: Imre Ariel , Szmolka Ama , Olasz Ferenc , Nagy Béla
Published: September 2015

The aim of these studies was to assess residual virulence and early protective capacity of a negatively markered live attenuated vaccine candidate Salmonella Enteritidis mutant against a highly virulent S. Enteritidis strain using a dayold chicken model. Nonflagellated FliD negative mutants of Salmonella Enteritidis 11 (SE11) with and without the virulence plasmid proved to be sufficiently attenuated (limited invasiveness in vitro/in vivo) without reduced ability to colonise chicken gut. The early protective activity of a nonflagellated, virulence-plasmidcured (fliD–, pSEVΔ) mutant against organ invasion, caecal colonisation and faecal shedding by the highly virulent challenge strain S. Enteritidis 147 NalR proved to be effective and safe. The innate and adaptive immunity was demonstrable during the first four weeks of life, and the serological response was clearly distinguishable from the response induced by the wild parental strain. In conclusion, we provided data for the first time about a virulence-plasmid-cured, nonflagellated mutant of S. Enteritidis to serve as a basis for development of a negatively markered potential live oral vaccine against virulent S. Enteritidis in chicken.

Authors: Vincze Boglárka , Kutasi Orsolya , Baska Ferenc , Szenci Ottó
Published: September 2015

The aims of this study were to detect physiological changes in blood biochemical parameters throughout gestation, to compare the findings in nonpregnant and pregnant Lipizzaner mares in early-mid and late pregnancy, and to provide reference values for clinical chemistry parameters in this horse breed. A total of 136 venous blood samples were collected from 20 pregnant and 10 nonpregnant (control) asymptomatic Lipizzaner broodmares for biochemical analyses. Twelve parameters (albumin, total protein, urea, triglycerides, glucose, creatinine, alkaline phosphatase, aspartate transaminase, glutamate dehydrogenase, gammaglutamyltransferase, creatine kinase and lactate dehydrogenase) were measured. For the statistical analyses, correlation, analysis of variance and Kruskal–Wallis H-test were used to evaluate the possible associations between parameters. Serum triglyceride levels proved to be significantly different in pregnant mares compared to the control group. Total protein and urea levels significantly decreased, while glucose, triglyceride and glutamate dehydrogenase values increased from approx. the fifth month of gestation until parturition. Four biochemical parameters (albumin, aspartate transaminase, total protein and urea) were lower and three other variables (glucose, alkaline phosphatase and creatinine) were significantly higher in late-term pregnant mares than in mares in early or mid-gestation. It is concluded that reference values not only reflect the species, breed and sex but also the reproductive status of animals.

Authors: Bende Balázs , Kovács Krisztina Borbála , Solymosi Norbert , Németh Tibor
Published: September 2015

The objective of this study was to describe the epidemiology of canine urolithiasis in Hungary in order to determine the annual incidence of urolithiasis and to identify breeds at risk for different types of urolithiasis. Data of a total of 2,543 canine uroliths analysed in the laboratory of the Budapest Urolith Centre were evaluated retrospectively from 2001 to 2012. Logistic regression was used to assess odds ratios for the proportion of each affected breed compared to those of crossbreeds. The annual incidence of urolithiasis was evaluated by the number of submissions compared to the estimated number of dogs in the population from which the samples originated. Epidemiologic data revealed a relatively high and increasing proportion of struvite urolithiasis. Statistical analysis of breed predispositions resulted in the detection of breeds not having been reported at risk (e.g. Bernese Mountain dog — struvite, Bichon Frise, Bolognese, Tibetan Terrier — purine, French Bulldog — cystine). Conflicting results were revealed for some other breeds previously described as being affected by certain types of urolithiasis (Chihuahua, Pekingese, Shih Tzu, English Cocker Spaniel). Regardless of the type of urolithiasis, its average cumulative incidence in the dog population of Hungary was found to be 1.76/10,000/year.
Coxiella burnetii antibody dynamics in heifers born to vaccinated versus non-vaccinated dams in a chronically infected dairy herd
Authors: Tutusaus Joan , Garcia-Ispierto Irina , López-Gatius Fernando
Published: September 2015

This study was designed to compare Coxiella burnetii antibody dynamics in heifers born to vaccinated or non-vaccinated dams in a single high-producing dairy herd chronically infected with the bacterium. Antibody dynamics were examined from birth to the postpartum period in replacement heifers (n = 14) born to non-vaccinated dams (n = 7) or to dams that had been vaccinated on gestation days 171–177 (n = 7) and 192–198. Samples of blood, milk, faeces, vaginal fluid, colostrum and cotyledons (the latter two only at parturition) were obtained in the dams over the period from gestation days 171–177 to postpartum days 91–97. Blood samples were used to detect antibodies against C. burnetii and remaining samples for PCR identification of the bacterium. In their calves/heifers, blood samples for antibody determinations were collected from birth to postpartum at the time points 1–7 and 22–28 days and 3, 6 and 12 months of age; 90–96 and 210–216 days of gestation; and 22–28 days postpartum. All calves were born seronegative for C. burnetii. Irrespective of the shedding status of their mothers (7 were C. burnetii shedders), seroconversion occurred after colostrum intake in all calves born to seropositive cows (n = 9) and in two of three vaccinated seronegative dams. Thereafter antibody titres gradually declined and by 6 months of age all calves were seronegative. Seronegativity persisted until their first postpartum period. These findings indicate that cows vaccinated during advanced pregnancy transfer immunity to their calves via the colostrum. Maternal C. burnetii antibodies in calves persisted for three months in calves born both to seronegative vaccinated and seropositive dams.
Treatment of naturally acquired demodectic mange with amitraz in two harbour seals (Phoca vitulina)
Authors: Kim Kyoo-Tae , Lee Seung-Hun , Kwak Dongmi
Published: September 2015

Two male harbour seals (Phoca vitulina; 33 and 35 years old, respectively), housed since 2002 at a zoo for exhibition purposes, developed severe, multifocal and diffuse skin lesions. Skin scrapings and microscopy for parasites as well as pure cultures for bacteria and dermatophytes were carried out to identify the aetiological agent. Skin scrapings showed that lesions appearing on the seals were caused by an infestation of Demodex mites, which is uncommon in marine mammals, and were not due to other causative agents (parasites, bacteria or dermatophytes). Treatment with amitraz (0.01%) once a week for three weeks and with ampicillin (10 mg/kg SID per os) for six days eliminated the mites and resolved the clinical signs of demodectic mange in the harbour seals. The purpose of this report is to describe the successful treatment of naturally acquired demodectic mange with amitraz in harbour seals.

Authors: Alharbi Fahd Ali , Ahmed Mohamed Rifaat
Published: September 2015

Introduction

Hearing loss among kindergarten children is considered as a major health problem especially when there is a deficiency in routine hearing screening during the clinical examination. The aim of the study was to detect any pattern of hearing loss among kindergarten children in Jazan (Kingdom of Saudi Arabia).

Methods

A total of 1220 kindergarten students in Jazan (Kingdom of Saudi Arabia) were subjected to meticulous hearing evaluation using otological examination, Tuning fork tests, pure tone audiometry (PTA), speech audiometry, and tympanometry.

Results

We found that 18 kindergarten students had type C tympanogram (Eustachian tube dysfunction), 28 had type B tympanogram (secretory otitis media with conductive hearing loss), 4 had chronic otitis media with conductive hearing loss, and 6 had mild sensorineural hearing loss.

Conclusions

Early detection and eradication of hearing loss improves quality of life outcomes of children which reduces the incidence of social burden from unrecognized hearing loss.

Commentary on: Are we overpathologizing everyday life? A tenable blueprint for behavioral addiction research
Authors: de Timary Philippe , Philippot Pierre
Published: September 2015

Background

This paper is a commentary to the article entitled: “Are we overpathologizing everyday life? A tenable blueprint for behavioral addiction research”, by Billieux, Schimmenti, Khazaal, Maurage and Heeren (2015).

Methods and Aims

In this manuscript, we commented on two aspects developed by the authors. Billieux et al. (2015) propose that the recent development of propositions of behavioral addiction is driven by an unwise application of an addiction model to excessive behaviors and rests on a confirmatory research strategy that does not question the psychological processes underlying the development of the conduct. They also show that applying a process driven strategy leads to a more appropriate description of the reality of the behavior and conduct, in particular by describing a variety of motivations for the excessive behavior, which is central to understanding the nature of the conduct. We believe that this new approach, which is fruitful to the emerging domain of behavioral addictions, could also apply to the domain of addictions in general. The latter is characterized by the application of a generic biological model, largely influenced by animal models, focusing on neurophysiological determinants of addiction. This approach may have decreased the attention paid to dimensions of addictions that are more specifically human. We will firstly briefly argue on the limitation of this neurophysiological addiction model for the field of excessive behavioral conducts. Secondly, we will argue for an approach centered on the differentiation of motivations and on the adaptive dimension of the behavior when it first developed and on the evocation of a transition where the conduct became independent of its original function.

Conclusions

The emerging domain of behavioral addictions, where no animal model has been developed so far, may bring a new reflection that may apply to the domain of addictions in general, with a specific attention to human questions.
Eating disorder risk, exercise dependence, and body weight dissatisfaction among female nutrition and exercise science university majors
Authors: Harris Natalie , Gee David , d’Acquisto Debra , Ogan Dana , Pritchett Kelly
Published: September 2015

Background and Aims

Past research has examined eating disorder risk among college students majoring in Nutrition and has suggested an increased risk, while other studies contradict these results. Exercise Science majors, however, have yet to be fully examined regarding their risk for eating disorders and exercise dependence. Based on pressures to fit the image associated with careers related to these two disciplines, research is warranted to examine the potential risk for both eating disorder and exercise dependence. The purpose of this study is to compare eating disorder risk, exercise dependence, and body weight dissatisfaction (BWD) between Nutrition and Exercise Science majors, compared to students outside of these career pathways.

Methods

Participants (n = 89) were divided into three groups based on major; Nutrition majors (NUTR; n = 31), Exercise Science majors (EXSC; n = 30), and other majors (CON; n = 28). Participants were given the EAT-26 questionnaire and the Exercise Dependence Scale. BWD was calculated as the discrepancy between actual BMI and ideal BMI.

Results

The majority of participants expressed a desire to weigh less (83%) and EXSC had significantly (p = .03) greater BWD than NUTR. However, there were no significant differences in eating disorder risk or exercise dependence among majors

Discussion and Conclusions

This study suggested there was no significant difference in eating disorder risk or exercise dependence between the three groups (NUTR, EXSC, and CON).

The coccolithophorid Scyphosphaera apsteinii is here reported for the first time from waters off the west coast of the Baja California Peninsula. Scypho­sphaera apsteinii is the type species of the genus Scyphosphaera and had hitherto been recorded only in the Atlantic and Indian Oceans, the Gulf of Mexico, the Mediterranean, and the Caribbean Seas. Specimens were found in samples collected in nets off Isla de Guadalupe in January 2013. This recording thus extends the geographical distribution of S. apsteinii from the Central Pacific (Hawaii) to the Eastern Pacific (NW Mexico).

Range characteristics in non-material clauses in Mandarin Chinese
Authors: Guowen Yang
Published: September 2015

Range described in this article is a generalized term for some non-inherent participants of processes defined within the theoretical framework of Systemic Functional Grammar. This article discusses the characteristics of Range in non-material clauses in Mandarin Chinese by comparing its grammatical behaviour with that of inherent participants of processes and that of its counterpart in English. Due to the lexical and grammatical differences between English and Chinese, circumstantial elements that are commonly realized by prepositional phrases in English are more likely to be realized by nouns or nominal groups in Chinese, functioning as the elements of Range. Range in different processes in Chinese generally make complementary specifications of those processes. Compared with inherent participants of processes, Range is much less likely to change its position in the clause. It has a lower possibility to follow the preposition b? ? in the b? ? construction and to be the thematic element in the bèi ? construction. Furthermore, the Range is less likely than the inherent participants to have thematic status in the complement-theme construction and to be marked focus in the contrastive-emphatic construction.

Published: September 2015

Resumo Objetivo: Este artigo propõe a utilização da Análise de Lacunas de Melhoria (Improvement Gap Analysis – IGA) como método para gestão de compromissos, ou trade-offs, de estratégias operacionais. Desenho/metodologia/abordagem Uma pesquisa quantitativa foi aplicada a 32 clientes de um fabricante de móveis, que receberam seus produtos devidamente instalados em sua residência no período de janeiro a setembro de 2012, mensurando o desempenho atual e o nível de satisfação e insatisfação esperadas pelos clientes em função de alterações do desempenho de estratégias operacionais. Descobertas Este estudo demonstra que através do uso da IGA – Improvement Gap Analysis é possível verificar o impacto da alteração de desempenho das estratégias operacionais por meio da satisfação dos clientes. Limitações da pesquisa Uma limitação dessa pesquisa é proveniente da metodologia IGA – Improvement Gap Analysis quanto ao uso da insatisfação dos clientes como medida de relevância das estratégias operacionais. Outra limitação é que nesse estudo foi analisada a alteração do desempenho das estratégias operacionais denominadas qualidade, flexibilidade, velocidade, confiabilidade e custos. Porém são apresentadas na literatura outras possíveis estratégias operacionais ou critérios competitivos, sendo necessárias futuras pesquisas empíricas para verificar possíveis conflitos de recomendações gerenciais entre os respectivos critérios. Implicações práticas Gerentes devem estar cientes de qual é o foco das melhorias em estratégias operacionais e, em possíveis situações de conflito inerentes ao processo de gestão dos trade-offs de operações, qual estratégia operacional pode ter seu desempenho reduzido, não gerando insatisfação significativa aos clientes. As prioridades de melhorias recomendadas por métodos fundamentados na importância declarada podem ser equivocadas, pois a importância declarada pelos clientes pode alterar-se em função do desempenho. A IGA pode ser uma alternativa viável, pois é possível definir não somente “o que melhorar”, mas também “quanto melhorar” em relação ao desempenho das estratégias operacionais. Originalidade/valor O desempenho das estratégias operacionais tem sido gerenciado sob a óptica da importância fixa e apenas definindo “o que melhorar”. Entretanto, a importância pode se alterar em função do desempenho e pode ser necessário definir “o quanto melhorar”. Esse artigo confirma a alteração da importância da estratégia operacional em função da alteração de seu desempenho, e propõe a utilização do método IGA com uma adequação importante, não definindo apenas a suficiência da melhoria, mas também a configuração de alteração nas estratégias operacionais.
Impactos Econômicos do Código Florestal Brasileiro: uma discussão à luz de um modelo computável de equilíbrio geral
Authors: Diniz Tiago , Ferreira Filho Joaquim Bento
Published: September 2015

Resumo:O trabalho analisa os impactos econômicos decorrentes da aplicação do Código Florestal, na sua nova versão e na anterior, sobre o Brasil e suas regiões. Para tanto, foram analisados três cenários distintos de aplicação do código por meio de um modelo de equilíbrio geral inter-regional, o TERM-BR, a partir do qual se podem obter os resultados a nível nacional e regional. Os dados básicos foram obtidos por meio de estudos realizados via imagens de satélite e compatibilizados com as informações de uso do solo provenientes do Censo Agropecuário de 2006. As conclusões mostraram que as restrições mais brandas da nova legislação, de fato, desdobram-se em menores impactos econômicos. Com o novo Código Florestal, a adequação às restrições legais implicaria redução de 0,19% do PIB do País ou de 0,17%, quando utilizado o mecanismo de compensar o déficit de Reserva Legal em outro estado. Na versão anterior do código, por sua vez, esse percentual seria de 0,37% do PIB. Esses resultados agregados, contudo, têm diferenças significativas quando analisados entre as regiões do Brasil, uma vez que, regionalmente, as incidências legais são distintas em cada um dos cenários.
Alzheimer and vascular brain diseases: Focal and diffuse subforms
Authors: Engelhardt Eliasz , Grinberg Lea T.
Published: September 2015

Alois Alzheimer is best known for his description of the pre-senile neurodegenerative disease named after him. However, his previous interest in vascular brain diseases, underlying cognitive and behavioral changes, was very strong. Besides describing the Arteriosclerotic atrophy of the brain and the arteriosclerotic subtype of Senile dementia which he viewed as main forms of vascular brain diseases, he also identified and described a series of conditions he considered subforms. These may be divided, as suggested by the authors of the present paper, into 3 groups: gliosis and sclerosis, subcortical atrophies, and apoplectic. The subforms of the three groups present characteristic neuropathological features and clinical, cognitive and behavioral manifestations. These provide the basis, together with part of the main forms, for the contemporary condition known as Vascular Cognitive Impairment.
A patient with a long history of relapsing psychosis and mania presenting with anti-NMDA receptor encephalitis ten years after first episode
Authors: Simabukuro Mateus Mistieri , Freitas Christian Henrique de Andrade , Castro Luiz Henrique Martins
Published: September 2015

Anti-N-methyl- D-aspartate receptor (NMDAR) encephalitis is a recently discovered autoimmune disorder, in which antibodies target NMDARs in the brain, leading to their removal from synapses. Early in the disease course, patients often present with marked psychosis and mood disturbances (i.e. mania, depression), explaining why most of these patients are first seen by psychiatrists. Hence, autoimmune encephalitis is receiving growing attention from psychiatry, mainly owing to concerns over misdiagnosing immunomediated and potentially curable disorders as primary psychiatric disorders, such as schizophrenia or major depressive disorder. Although anti-NMDAR encephalitis occurs in the context of new-onset psychiatric symptoms, there is a lack of information on differential diagnosis and treatment of this disorder after a long-term diagnostic history of functional psychiatric disorders. We report a case of a patient with a long history of bipolar affective disorder evolving with anti-NMDAR encephalitis, initially misdiagnosed as non-organic psychosis.

Authors: Maia Luiz Cláudio Gomes , Santos Maria De Souza Lima
Published: September 2015

O objetivo deste artigo é compreender como os gestores do Sistema de Bibliotecas da UFG (Sibi/UFG) utilizam os indicadores de avaliação do MEC durante o processo de aquisição de recursos informacionais. A investigação foi realizada por meio de entrevistas semiestruturadas e analisadas de forma descritiva, por meio de um estudo de caso a partir do qual se buscou interpretar as informações, tendo como base o referencial teórico que norteou o desenvolvimento da pesquisa, com os gestores das bibliotecas e com os bibliotecários gerentes de atendimento. Os resultados apontam que há uma homogeneidade acerca do processo de avaliação e que a biblioteca precisa definir, junto ao corpo docente, e a administração da Instituição, uma Política de Formação de Acervo que deverá orientar o processo de aquisição de materiais bibliográficos nos diversos formatos, tanto para cursos existentes quanto para novos. Contribuindo, dessa forma, para um melhor atendimento às novas diretrizes estabelecidas pelo MEC e, consequentemente, resultando em melhorias para a biblioteca universitária.
Repositórios digitais confiáveis para documentos arquivísticos: ponderações sobre a preservação em longo prazo
Authors: Santos Henrique Machado dos , Flores Daniel
Published: September 2015

A evolução da tecnologia da informação e a sua inserção na Arquivologia proporcionou rupturas no conceito e na concepção de documento arquivístico que se refletem nas práticas de gestão, preservação e acesso. A complexidade e a especificidade do documento arquivístico digital implica na necessidade de um tratamento diferenciado se comparado aos documentos tradicionais em suportes analógicos. Além disto, é preciso garantir a integridade e a autenticidade dos documentos digitais armazenando-os em um sistema confiável. Neste sentido, os repositórios digitais se configuram no âmbito global como a melhor alternativa para a preservação em longo prazo, entretanto, as ações para gerar confiabilidade ainda são pouco difundidas. Este artigo tem por objetivo realizar uma reflexão sobre os requisitos para desenvolver um repositório digital confiável. A metodologia utilizada consiste na revisão de materiais previamente publicados nos últimos vinte anos, a qual aborda os dados de forma qualitativa, enfatizando os estudos mais recentes. Dentre os avanços mais significativos, salienta-se a realização de auditorias para que os repositórios possam ser certificados como "confiáveis". Além disso, é reforçada a utilização de normas e recomendações, e a definição prévia de políticas de preservação digital que considerem a confiabilidade durante todo o ciclo documental, configurando assim uma custódia confiável.

ResumoA pimenta bico, pertencente à espécie Capsicum chinense, é muito utilizada na culinária brasileira no preparo de diversos pratos e também em conservas. Por se tratar de um alimento altamente perecível, faz-se necessária a utilização de métodos para a sua conservação, destacando-se o processo de secagem. O presente trabalho teve como objetivo determinar e analisar a cinética de secagem da pimenta bico em diferentes condições de temperatura e velocidade do ar de secagem. A pimenta foi submetida ao processo de secagem por meio de um secador de bandejas em camada delgada, com velocidade do ar de secagem controlada a 1,0; 1,5 e 2,0 m/s e temperatura de 40, 50 e 60 °C. As pimentas foram colocadas no interior do equipamento em bandejas removíveis de aço inoxidável e as amostras, pesadas periodicamente até o equilíbrio ser atingindo. Os modelos matemáticos de Page, Henderson e Pabis, Midilli e Kucuk, Thompson e Aproximação da difusão foram ajustados aos dados experimentais. O melhor ajuste foi determinado em função dos maiores valores do coeficiente de determinação (R2), menores valores de desvio médio relativo (P) e do erro médio estimado (SE). Os resultados obtidos mostraram que a secagem da pimenta é influenciada pela velocidade e temperatura do ar de secagem, visto que quanto maior a temperatura do ar de secagem, mais rapidamente obtém-se o equilíbrio de umidade das amostras. O modelo de Midilli e Kucuk foi o que se ajustou melhor aos dados experimentais. Os valores de difusividade efetiva encontrados variam de 1,65 × 10–10 a 5,01 × 10–10 m2/s e a energia de ativação varia de 98,42 a 108,13 kJ/mol.
Validity and Reliability Evidence for Assessing Holland's Career Types
Authors: Meireles Everson , Primi Ricardo
Published: September 2015

ABSTRACTProfessional interests are a synthesis of personal characteristics and function as a guiding factor for one's career choice. This study shows evidence of validity and reliability for the interpretation of the scores of a measure of career types. The responses of 1,265 high school students to 154 items from the Escala de Avaliação dos Tipos Profissionais de Holland (ATPH) ENT#091;Assessment Scale of Holland's Career TypesENT#093; were used. Exploratory and confirmatory factor analyses showed that the six-factor structure is appropriate and consistent to represent the RIASEC types. Evidence of convergent-discriminant validity of parcels of items was demonstrated to represent the latent factors of the ATPH Scale. Results of multidimensional analysis and phi correlation phi partially confirmed the hypothesis of circularity and congruence among the career types, which are organized in the acronym RASIEC. The implications of these results and study limitations are discussed.
Executive Functions: Influence of Sex, Age and Its Relationship With Intelligence

AbstractThe Tower of Hanoi is a tool used to evaluate executive functions. However, few studies describe what functions are evaluated in this test. This study investigates the executive functions, evaluated by the Tower of Hanoi (ToH), and the influence of gender, age and its relationship with intelligence. We evaluated 55 children and adolescents, between the ages of ten and 16, without diagnosed neuropsychiatric disorders. The results showed that the performance and time in to complete the Tower of Hanoi have no discriminative power when comparing age groups and sex; there was also no significant correlation found between the ToH and the execution quotient of the Wechsler Intelligence Scale for Children - Third Edition (WISC III), perceptual organization and the speed of processing. Only the subtest coding were positively related to the ToH, demonstrating that these instruments may be measuring related aspects of intelligence and executive functions, namely intelligence and working memory.
Rebalanceamento da Estrutura de Capital: Endividamento Setorial e Folga Financeira
Authors: Campos Anderson Luis Saber , Nakamura Wilson Toshiro
Published: September 2015

Admitindo-se um modelo em que o endividamento das empresas é fortemente influenciado pelo lado da oferta de recursos pelo fato de os credores e investidores (usuários do CAPM e de múltiplos de mercado) avaliarem sua exposição e nível de risco em bases relativas (empresas similares). Esse comportamento induz a estrutura de capital-alvo das empresas ao endividamento mediano do setor, restando aos gestores apenas gerenciar sua estrutura de capital em torno desse valor (folga financeira). Como objetivo, investigou-se o papel da folga financeira, avaliada como uma medida de endividamento relativo, e do endividamento setorial sobre o rebalanceamento da estrutura de capital das empresas. Para tanto, utilizou-se uma amostra inicial de empresas americanas com 32.309 observações-ano para estimar as medianas setoriais de 64 setores e uma subamostra de 5.380 observações, representando ainda 58 setores, para a construção de um painel balanceado por um período de 20 anos. Os resultados do painel dinâmico para o endividamento contábil indicam que o endividamento da empresa tende a acompanhar o endividamento setorial, porém tendem a reverter sua tendência em um período de dois anos. A velocidade de reversão está associada à folga financeira, ou seja, empresas mais distantes do endividamento mediano do seu setor convergem mais rapidamente.

LITERATURA NÃO-CANÔNICA DE DIVULGAÇÃO CIENTÍFICA EM AULAS DE CIÊNCIAS
Authors: Pinto Gisnaldo Amorim
Published: September 2015

Diferenciando a divulgação científica canônica da divulgação científica não canônica, este trabalho realiza uma análise de narrativas presentes em obras não canônicas de literatura, destacando suas potencialidades ao ensino de ciências. Foi possível localizar uma opção narrativa pela imaginação criadora, pela capacidade humana e por sua potencialidade criativa, elementos que são, nesse caso, motes fundamentais para reflexão sobre a vida humana e também sobre a ciência. Em especial na obra Meninos da planície, Cástor Cartelle, 2001, foi possível perceber uma contribuição para renovação do ensino de ciências, pois sua centralidade recai sobre a reflexão acerca da humanização dos sujeitos e não sobre a transmissão de conteúdos da ciência, embora essa dimensão, a da formação científica, esteja inequivocamente presente, sem prejuízos.
