Authors: Zbaravska Lesia , Chaikovska Olha , Semenyshena Ruslana , Duhanets Viktor
Published: May 2019

This study reports on interdisciplinary approach to teaching physics to the students majoring in agrarian and mechanical engineering. Physics plays a crucial role in mastering major disciplines by students of technical universities. Ukrainian higher education provides primarily mono-disciplinary approach to teaching academic and major subjects, so called teaching isolated disciplines. The interdisciplinary aspect of teaching physics corresponds to the requirements of modern society to educate competitive and qualified specialists in agricultural and engineering spheres. The study aims at defining the essence of interdisciplinary links between physics and major subjects, at specifying the peculiarities of job-focused physics tasks, at demonstrating the necessity of implementation the professional context in the process of studying. The paper investigates this issue by analyzing, comparing, systematizing the pedagogical literature.The study is based on monitoring and pedagogical experiment that proved the insufficient level of professional orientation of physics course. Pedagogical experiment was carried (out from 2014 to 2017). The students of State Agrarian and Engineering University in Podilya, Tavriyskiy State Agrarian University majoring in Agrarian Engineering and Agronomy and the students of Sumy National Agrarian University majoring in Agricultural mechanization took part in the survey. The sample involved 150 students. The study demonstrated such advantages of interdisciplinary approach to teaching physics through occupation-based task scenarios as student engagement and highly qualified specialists, subject interaction. The results of the experiment showed the insufficient level of professional competence of physics course. The material in this article, he patterns of physics course tasks accompanied by illustrations for students of mechanical engineering and agrarian departments, in particular, can be used in educational process.

Chinese L2 acquisition of sense relatedness for shàng “to go up”
Authors: Liang Haiyan , Sullivan Karen
Published: May 2019

This paper examines the relations between the senses of the Chinese polysemous verbshàng“to go up”, in an effort to understand how the various senses of polysemous words are organized in the L1 and L2 lexicons and to shed light on the role they might play in L2 polysemy acquisition. To this end, we analyzed the senses of shàng at the conceptual level, then used these findings to inform an empirical study of the sense relatedness as perceived by L1 and L2 participants. A developmental pattern is identifiable across the L2 proficiency groups. Specifically, the sense relations identified by the L2 groups increasingly approximate those identified by L1 as their proficiency level grows. Both native speakers and learners base their perceptions of sense relatedness on purported conceptual metaphors as well as other factors such as transitivity, function and concreteness – though the two groups apply these concepts in different ways. These findings suggest that learners can access the same conceptual tools as native speakers, but are using these tools in a way that differs from native speakers. Conclusions support the cognitive motivations behind polysemous senses and teaching-oriented findings that overlap in L1 and L2. Conceptual universals should be helpful in L2 vocabulary acquisition.

Quasi-Linearisation Methods for a Non-Linear Heat Equation with Functional Dependence
Authors: Leszczyński Henryk
Published: May 2019

We consider a heat equation with the non-linear right-hand side which depends on certain Volterra-type functionals acting on the unknown function and on its gradient. We give some natural sufficient conditions for the existence and uniqueness of solutions to this equation. The solution is obtained as a limit of a fast convergent sequence of successive approximations obtained by the quasi-linearisation method.
Typology and contexts of article errors: Investigation into the use of English articles by Hong Kong Cantonese ESL learners
Authors: Chan Alice Yin Wa
Published: May 2019

This paper provides a taxonomy of errors in the use of English articles by Hong Kong Cantonese ESL learners. A study was conducted with 387 Hong Kong Cantonese ESL learners, including 65 students from three local universities and 322 students from five local secondary schools. They did two free writing tasks of about 200–300 words. Over 600 pieces of free writing were obtained. The use of English articles was analyzed and errors were identified. Irrespective of learners’ proficiency levels, similar types of article errors have been observed. While over-extension errors and under-extension errors are both quite common, co-occurrence errors are nearly non-existent. Intended generic reference triggers most problems, although this reference has been least attempted. The function of the noun phrase in which an article error occurs may play a part in error severity, with Object creating most problems for learners, yet the precise effects of noun functions are yet to be determined. It is suggested that more emphasis be put on the teaching of English articles to learners at different proficiency levels. Advanced learners, such as university students, should be engaged in metalinguistic analyses uncovering the subtle differences between the use of different articles in the same linguistic context.
How Much Should a Person Know? Moral Inquiry & Demandingness
Authors: Hartford Anna
Published: May 2019

An area of consensus in debates about culpability for ignorance concerns the importance of an agent’s epistemic situation, and the information available to them, in determining what they ought to know. On this understanding, given the excesses of our present epistemic situation, we are more culpable for our morally-relevant ignorance than ever. This verdict often seems appropriate at the level of individual cases, but I argue that it is over-demanding when considered at large. On the other hand, when we describe an obligation to know that avoids over-demandingness at large, it fails to be sufficiently demanding in individual cases. The first half of this paper is dedicated to setting up this dilemma. In the second half, I show that it cannot be easily escaped. Finally, I suggest that this dilemma impedes our ability to morally appraise one another’s ignorance, and even our own.
Feasibility of Noncontact Chemical Identification and Mapping for Steel Corrosion Using Portable Raman Spectroscopy
Authors: Zhou Zijie , Park Jeong Hoon , Kang Gyu-Hong , Yun Hae-Bum
Published: May 2019

This article presents the portable Raman spectroscopy as a novel noncontact chemical sensing technique for steel corrosion analysis that can be used in field bridge inspection. To validate its feasibility, the portable system was tested with four steel specimen sets by gradually increasing the complexity of corrosion products in atmospheric corrosion. A software algorithm was developed to process a large set of Raman spectra for automated chemical identification and two-dimensional chemical mapping. The portable Raman spectroscopy has advantages over conventional nondestructive evaluation techniques because (i) absolute chemical identification of corrosion products is possible without involving field calibration, (ii) no surface preparation is necessary, (iii) it allows for field inspection for periodic or in situ corrosion analysis, (iv) and because, being a noncontact portable sensing technique, it can be combined with a drone or robot for automated bridge inspection.
Evaluation of the Effect of Exposure Duration and Fiber Content on the Mechanical Properties of Polypropylene Fiber-Reinforced UHPC Exposed to Sustained Elevated Temperature
Authors: Rasul Mehboob , Ahmad Shamsad , Adekunle Saheed Kolawole , Al-Dulaijan Salah U. , Maslehuddin Mohammed , Ali Syed Imran
Published: May 2019

This article presents the results of an experimental study conducted to assess the effect of sustained elevated temperature on the mechanical properties of ultrahigh performance concrete (UHPC). UHPC mixtures were prepared with four different dosages of polypropylene (PP) fibers, and each mixture was exposed to a sustained pre-spalling elevated temperature of 300°C for five durations. The experimental data indicate that the used PP fibers were effective in providing sufficient strength and ductility to UHPC mixtures at room temperature. However, the PP fibers ceased to function as reinforcement in UHPC specimens that were exposed to the elevated temperature for 60 minutes. With an increase in the exposure period after melting of the fibers, the specimens exhibited a brittle mode of failure accompanied with an enhancement in the compressive strength and compressive modulus of toughness and a reduction in the modulus of elasticity and flexural strength. The significance of two variables (exposure duration and fiber content) was evaluated, and correlations between the mechanical properties and selected parameters were obtained by conducting a statistical analysis of the experimental data.
Historical Consciousness and Ethnicity: How Signifying the Past Influences the Fluctuations in Ethnic Boundary Maintenance
Authors: Zanazanian Paul
Published: May 2019

Theorists tend to limit ‘history's’ role in the dynamics of ethnicity to that generally played by collective memory. By bringing the notion of historical consciousness to the fore, new possibilities may, however, emerge for discerning how history, as one cultural mode of remembering among many others, impacts both ethnicity delineations and fluctuations in boundary maintenance. In encapsulating the many forms of commemoration as well as the different dimensions of historical thinking, the contribution of historical consciousness accordingly lies on how group members historicize temporal change for moral orientation in time. By likewise signifying past events for negotiating their ethnicity and agency toward the ‘significant Other’, social actors gate-keep group boundaries. And, depending on their capacity and willingness to recognize the ‘significant Other's’ moral and historical agency in the flow of time, they can transform group delineations and render ethnic boundaries more porous.

Binary expression systems like the LexA-LexAop system provide a powerful experimental tool kit to study gene and tissue function in developmental biology, neurobiology, and physiology. However, the number of well-defined LexA enhancer trap insertions remains limited. In this study, we present the molecular characterization and initial tissue expression analysis of nearly 100 novel StanEx LexA enhancer traps, derived from the StanEx1 index line. This includes 76 insertions into novel, distinct gene loci not previously associated with enhancer traps or targeted LexA constructs. Additionally, our studies revealed evidence for selective transposase-dependent replacement of a previously-undetected KP element on chromosome III within the StanEx1 genetic background during hybrid dysgenesis, suggesting a molecular basis for the over-representation of LexA insertions at the NK7.1 locus in our screen. Production and characterization of novel fly lines were performed by students and teachers in experiment-based genetics classes within a geographically diverse network of public and independent high schools. Thus, unique partnerships between secondary schools and university-based programs have produced and characterized novel genetic and molecular resources in Drosophila for open-source distribution, and provide paradigms for development of science education through experience-based pedagogy.
Arraigo y planificación urbana en grandes proyectos urbanos. El caso del Nuevo Aeropuerto de Quito
Authors: Sandoval-Luna Alejandra , Ibarra-Alonso Macarena
Published: May 2019

La urbanización planetaria ha comprometido un crecimiento urbano que transforma los territorios y a sus habitantes. Ante ello, la planificación territorial ha dado respuestas urgentes desde la esfera gubernamental y municipal a problemas de la escala local, atendiendo las necesidades de crecimiento sustentable de las ciudades en procura del resguardo del bienestar y de las identidades locales. El artículo propone cuatro factores clave para la planificación y la gestión de la ciudad de manera responsable y coordinada con la población afectada, a partir del caso de estudio del Nuevo Aeropuerto Internacional de la ciudad de Quito (NAIQ). Se examina cómo el arraigo de la comunidad de Tababela, lugar donde se emplazó el aeropuerto, fue modificado con su presencia y se plantea que la organización social, la transmisión de tradiciones, los valores solidarios y el liderazgo son aspectos claves para el arraigo ante la llegada de grandes proyectos urbanos.
O uso da problematização e do pêndulo simples para o estudo da gravidade
Authors: Dutra Carlos Maximiliano , Souza Melicia De
Published: May 2019

No presente trabalho propomos um experimento de Pêndulo Simples para determinação da aceleração da gravidade por estudantes de uma Escola de Ensino Médio do município de Uruguaiana/RS. O Pêndulo Simples consiste em um “peso” suspenso por um fio e o experimento consiste na análise do período de oscilação deste pêndulo. Verificou-se experimentalmente a independência do período do Pêndulo em relação à massa do seu “peso” e espessura do seu fio e apresentando uma variação com o comprimento do seu fio, fator esse que influencia na determinação da aceleração da gravidade pela experiência do Pêndulo Simples. Como resultado encontrou-se um valor médio de g = 9,92 m/s2, que representa um erro relativo de 1,30% em relação ao valor teórico de Uruguaiana, corrigido por altitude e latitude. O uso da experimentação proporcionou o desenvolvimento do espírito científico nos estudantes numa interação mais significativa entre eles e o conteúdo, tornando o processo de ensino aprendizagem mais dinâmico e atrativo.

Published: May 2019

A expansão do Ensino Superior brasileiro nos últimos anos e a adoção de políticas públicas, trouxeram à universidade um número expressivo de estudantes provenientes de escolas públicas e em condições socioeconômicas adversas. Diante dessas condições é necessário que se ofereçam meios para incentivar a permanência e o êxito dos estudantes. Desse modo, o presente artigo objetiva analisar o rendimento acadêmico e a permanência de alunos ingressantes nos cursos superiores do Instituto Federal do Ceará - Campus Fortaleza, observando-se sua progressão através do índice de Rendimento Acadêmico (IRA), a fim de obter dados sobre o impacto da política de cotas na instituição. A amostra foi composta por alunos regularmente matriculados, para cálculo do desempenho, e por egressos sem êxito, para cálculo da evasão. A análise de rendimento revelou que os alunos não cotistas têm um rendimento superior aos cotistas, mas não há uma diferença significativa entre os dois grupos. Na análise da evasão, verificou-se que o número de alunos cotistas evadidos foi menor em quatro dos sete períodos analisados. Conclui-se que é necessário que haja uma mediação para redução dessa diferença a fim de incluir efetivamente os alunos cotistas na instituição.
Análise dos projetos pedagógicos do Curso de Tecnologia em Processos Gerenciais com foco no tema: relacionamento interpessoal

Published: May 2019

Este trabalho visou revisar os Projetos Pedagógicos do Curso (PPC) Tecnologia em Processos Gerenciais (TPG) ofertados nos campi do Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Sul (IFRS). Para tanto, analisou suas disciplinas e conteúdos quanto à abordagem do tema “Relacionamento Interpessoal”, devido ao fato que esta habilidade é valorizada no mercado de trabalho, sendo muitas vezes fator de diferenciação entre profissionais com mesma formação. O problema que norteia este trabalho foi: está prevista a abordagem do tema relacionamento interpessoal nos PPCs dos campi do IFRS que ofertam o Curso de TPG? O objetivo principal deste trabalho foi examinar os PPCs fazendo comparações acerca das ementas das disciplinas relacionadas ao tema. Por meio de pesquisa bibliográfica, foi feita análise documental dos PPCs de todos os campi que ofertam o Curso e observou-se que o conteúdo não é abordado em todos os PPCs. Um dos resultados apontou a importância de definir a inclusão deste conteúdo de forma padronizada numa disciplina específica, dada a relevância deste tema na formação destes Tecnólogos.

Published: May 2019

Sob premissas de centralização do processo ensino-aprendizagem no estudante e do rompimento com a tradição expositiva, a sala de aula invertida (SAI) se apresenta como uma tendência educacional no ensino superior. Nesse modelo didático, os alunos estudam antecipadamente os conteúdos, a partir de materiais preparados e encaminhados pelo professor, e destinam o tempo em sala para a operacionalização do conhecimento por meio de metodologias ativas. Os resultados das pesquisas com estudantes estrangeiros são significativos e vêm tendo forte repercussão acadêmica, particularmente nas ciências exatas. No entanto, permanecem insuficientes as evidências colhidas com professores e em contextos peculiares, como o das universidades públicas no Brasil. Este artigo relata duas experiências com a SAI, no primeiro semestre de 2017, nas disciplinas Geometria Analítica e Física Introdutória de um curso de Licenciatura em Ciências Exatas. Com intenção vicária e exemplar, os docentes responsáveis compartilham sua familiaridade com a proposta, descrevem suas opções metodológicas, e apresentam evidências da prática que sugerem potencialidades e desafios para a adoção e a implementação da SAI.

O uso de identidades vetoriais associado ao tensor de Levi-Civita
Authors: Nascimento Luciano
Published: May 2019

A álgebra e o cálculo vetorial são freqüentemente usados em muitos ramos da Física, por exemplo, mecânica clássica, teoria eletromagnética, Astrofísica, Espectroscopia, etc. Neste trabalho é utilizada a notação de Levi-Civita e do tensor delta de Krönecker que simplifica consideravelmente cálculos que são provadas neste artigo. Algumas das identidades foram provadas usando símbolos de Levi-Civita por outros matemáticos e físicos. Muitas das simplificações decorrem de usar a convenção da soma de Einstein sobre índices repetidos no espaço tridimensional.
Intra-lingual pragmatic variation in Mandarin Chinese apologies
Authors: Su Yunwen , Chang Yufen
Published: May 2019

This study investigates regional and gender variations of apologies in Putonghua ‘Standard Mandarin’ and Guoyu ‘Taiwanese Mandarin’. Production data were elicited from 40 participants from northern Mainland China and 34 from Taipei using an oral discourse completion task. Results showed that speakers in both regions employed a similar sequence of strategies and demonstrated similar preferences for context-dependent strategies in their apologies, but Mainland speakers used a significantly greater number of strategies than Taiwan speakers. Gender differences were observed in the apologies produced by Taiwan speakers regarding their use of illocutionary force indicating devices. The study found an interaction effect of power relation and region, with Mainland speakers sounding more apologetic than Taiwan speakers, but no interaction effect of power relation and gender; the effect of severity of offence was not clear, which could be attributed to the gap between the predetermined level of severity and speakers’ actual perception of it in each scenario.

Published: May 2019

Simulated learning experiences (SLEs) assist students to acquire knowledge and skills and are an effective teaching tool in physiotherapy education. The aim of this project was to explore physiotherapy student attitudes towards SLEs as a preparatory component of an introductory clinical placement. The project was a quasi-experimental, pre/post-test repeated measures design. Participants were second year physiotherapy students (n = 57) allocated to a placement which included one week of SLEs and three weeks in a healthcare setting. The SLE week consisted of sessions to develop students’ clinical skills in preparation for placement. Data on participant attitudes towards SLEs were collected via anonymous survey before and after the SLE week, and at the completion of the three week clinical placement. Attitudes of respondents (n = 43) towards SLEs were significantly more positive at the completion of the SLE week. At the completion of the three week clinical placement, all responses remained more positive than at the commencement of the project, however participant responses were  generally less positive than at the conclusion of the week of SLEs. Students valued the use of SLEs in preparing for introductory clinical placements. Simulated learning experiences should be considered as a useful tool for pre-placement preparation for early year physiotherapy.

The Tension and Intersection between my Personal and Professional Identities as an Egyptian, Muslim Woman
Authors: Barakat Maysaa
Published: May 2019

In this autoethnography I connect my personal experience as an Egyptian, Muslim Woman and my professional experience as an Educator to the complex intercultural context in which I found myself (Ellis & Bochner, 2000). Using one critical incident (please see “we are not in America here” vignette) as a point of reflection on the influence that my background has had on my personal and professional learning, career choices, and how my perceptions of marginalization as an Egyptian, Muslim, Woman impacted my attitudes and behaviors and led me to focus on the importance of cultural competence for educators. Now more than ever, because of the divisive and hate rhetoric which is dominating the public and political arenas, I find myself concerned with the encompassing question of how could educators understand the struggles of students who are members of venerable minority groups, so that they could better support their learning?
"Taking Away the Occasion for Violence": The Quaker Peace Testimony and Law Enforcement in the Justice and Policy Studies Department at Guilford College
Authors: Fernandes Jane K. , Giles Hollyce "Sherry" , Lawrence Barbara J. , Hinson James E. , Morris Wesley
Published: May 2019

The mid-sized southern city of Greensboro, North Carolina has not been spared from the crisis in policing gripping the United States. The city has a history of racial conflict and violence involving the police, most notably the 1979 Massacre where five anti-Klan protestors were killed by Neo-Nazi and Klan members. It is also the site of renowned movements for social justice; in 1961, four North Carolina Agricultural and Technical State University freshmen sparked the Sit-In movement, and in 2005, the first Truth and Reconciliation Commission in the United States, which addressed the Massacre, took place in Greensboro. Through partnerships with activists, police, and other community members, the Justice and Policy Studies Department (JPS) at Guilford College works to strengthen police-community relations in Greensboro. The Quaker peace testimony, which calls for “taking away the occasion for violence,” inspires and guides these efforts. This article explores the ways that JPS and its community partners prepare students to take away the occasion for violence in policing and the criminal justice system. Guilford’s president, two JPS professors, a Deputy Chief of the Greensboro Police Department and a community organizer with the Beloved Community Center share their insights regarding this critical topic.
The (Mis)Uses of Race in Research on College Students: A Systematic Review
Authors: Johnston-Guerrero Marc P.
Published: May 2019

Race has been one of the most controversial subjects studied by scholars across a wide range of disciplines as they debate whether races actually exist and whether race matters in determining life, social, and educational outcomes. Missing from the literature are investigations into various ways race gets applied in research, especially in higher education and student affairs. This review explores how scholars use race in their framing, operationalizing, and interpreting of research on college students. Through a systematic content analysis of three higher education journals over five years, this review elucidates scholars’ varied racial applications as well as potential implicit and explicit messages about race being sent by those applications and inconsistencies within articles. By better understanding how race is used in higher education and student affairs research, scholars can be more purposeful in their applications to reduce problematic messages about the essentialist nature of race and deficit framing of certain racial groups.

Multiculturally competent student affairs educators are required to effectively meet the needs of today’s diverse student population. However, little is known about how educators acquire these skills. This study examined the multicultural awareness, knowledge, and skills gained by student affairs educators through their participation in NCORE, an experiential conference exploring race and ethnicity. Results of the study have implications for graduate preparation programs and professional development opportunities for student affairs educators.
Racial Color-Blindness and Privilege Awareness in Relation to Interest in Social Justice among College Students
Authors: Garrett-Walker Ja’Nina , Martin Poole Sonja , Williams Sienna L. , Banks Caleb J. , Stallings Justine A. , Balgobin Kristian R. , Moore Dylan P.
Published: May 2019

An online survey examining racial color-blindness, privilege awareness, and social justice was administered to a sample of 381 college students (Mage = 20.53, SD = 4.35). Using multiple regression, increases in heterosexual and class privilege awareness predicted increases in student interest in social justice while increased levels of racial color-blindness predicted decreases in student interest in social justice. These findings suggest that racial color-blindness may serve as a barrier to engagement in social justice while heterosexual and class privilege awareness may buffer the aforementioned barrier. Professors and university administration should consider ways in which they infuse conversations around diversity, privilege, and racial color-blindness into their curriculum.
Choque de gestão petista? Repensando a relação do PT com a reforma gerencial
Authors: FONTOURA LEANDRO HEITICH
Published: May 2019

RESUMO Líderes petistas utilizando o slogan “choque de gestão” e defendendo políticas como avaliação de desempenho, premiação por resultados e transferência de serviços para organizações sociais não são encontrados facilmente, uma vez que são conceitos e instrumentos vinculados ao PSDB, seu principal adversário político. Este artigo apresenta administrações municipais petistas que revisam o tradicional discurso antirreforma do partido. São usados dados de uma pesquisa que buscou identificar prefeitos do PT alinhados aos princípios gerenciais. Para verificar a adesão de administrações petistas à APG, o estudo avaliou até que ponto implementaram políticas vinculadas a essa agenda. A pesquisa definiu cinco princípios básicos da APG: Planejamento; Meritocracia; Parcerias e contratualização; Participação e cidadania; Eficiência e modernização. Esses eixos contemplam 20 políticas de gestão, que formaram o questionário norteador das 10 entrevistas do estudo. A partir da pesquisa sobre a aplicação da agenda da APG em cinco administrações do PT, constatou-se que prefeitos da legenda, diante dos problemas urbanos das cidades, dos entraves da burocracia pública e do aumento das demandas sociais, aos poucos implementam políticas associadas aos adversários com a finalidade de tornar a máquina pública mais eficiente e oferecer serviços mais qualificados ao cidadão. A novidade trazida por este artigo é uma revisão do discurso petista. Essa mudança de postura não se dá sem tensionamentos com setores da legenda e do funcionalismo público, mas aponta para uma tentativa de revisão do posicionamento do partido.

Abstract The rumen is the most studied organ with regard to the symbiotic interaction between host and microbiota in the digestive tract of ruminants. Thus, this study aimed at evaluating the effects of including virginiamycin and salinomycin to the supplement for cattle fed tropical grass diet during the rainy season. Three treatments were set: control - mineral supplement COMIGO - Cria 61-F2 (MS); virginiamycin - MS + virginiamycin (Phigrow (r)) 100 mg/animal/day; salinomycin - MS + salinomycin (Posistac(r)) 108 mg/animal/day for the experiment 1 (performance) and experiment 2 (ruminal metabolism). The control showed higher Mineral supplement intake (MSI) (P <0.05), the virginiamycin had higher average daily gain (ADG) (P> 0.05) and better financial efficiency. Biometric measurements showed no differences (P> 0.05), suggesting a change in the ADG composition. There was no difference (P> 0.05) for dry matter digestibility (DMDIS), acid detergent fiber digestibility (ADFDIS), ruminal pH and ammoniacal-N. The virginiamycin had the highest effective neutral detergent fiber (NDF) degradability (P> 0.05) in the passage rates of 2 and 5%; the degradability rates were similar to control treatement and higher than that of salinomycin at the rate of 8%/hour. The virginiamycin or salinomycin can be conveyed to the MS, but do not promote significant effects on ruminal pH, ammoniacal-N, DMDIS and ADFDIS; but virginiamycin promoted greater effective degradability of NDF.

Abstract The allometric growth of male and female naturalized pig breeds (Nilo, Piau, Moura, and Monteiro) was evaluated regarding hip height, snout length, and head length using the allometric equation. Body measurements generally show later growth in relation to the snout length and earlier growth in relation to the head length and hip height. When comparing breeds of pigs, female Moura animals showed later growth of the characteristics linked to muscle (thoracic circumference, body length, and longitudinal diameter) than of head length. Nilo females showed characteristics such as shoulder length, rump length and interschiadic distance earlier than snout length. There were differences between the breed and gender in terms of development times for the different parts of the body, showing that breeding systems and use of these animals have to be specific for each breed.

Resumo O objetivo deste trabalho foi avaliar a interação entre sistemas produtivos e estações do ano sobre a qualidade do leite bovino. Três propriedades foram avaliadas mensalmente, durante as estações, em quatro graus de especialização dos sistemas de produção: altamente especializado, especializado, semiespecializado e não especializado. Em termos de qualidade do leite, consideraram-se os teores de gordura, proteína, sólidos totais, contagem de células somáticas, contagem bacteriana total, acidez titulável em graus Dornic, densidade, índice crioscópico, estabilidade ao alizarol, potencial de hidrogênio (pH) e teste de redução do azul de metileno. Além destes, devido à sua importância para o rendimento industrial dos produtos lácteos de base proteica, foi realizado o fracionamento da proteína total do leite em equivalente proteico do nitrogênio não proteico, da proteína verdadeira e da caseína. A acidez Dornic foi maior na primavera e no inverno, enquanto os valores mais elevados de contagem de células somáticas foram no verão. Os teores de proteína total e proteína verdadeira foram menores durante o verão e elevaram-se os sólidos totais no outono. Com a diminuição dos níveis de especialização das propriedades rurais, observaram-se aumento na contagem bacteriana total e diminuição do nitrogênio não proteico. A densidade apresentou comportamento inverso ao da gordura, enquanto o potencial de hidrogênio (pH) se expressou de modo antagônico à acidez titulável. Na análise multivariada dos dados, foi possível identificar as combinações entre estratos produtivos e estações do ano que apresentavam a melhor qualidade da proteína do leite. Nesse sentido, todos os arranjos de sistemas de produção com o outono, o sistema altamente especializado no inverno, o semiespecializado no verão e o especializado na primavera tiveram qualidade proteica positiva, destacando-se pelas menores contagens de células somáticas a combinação entre a estação primavera e o sistema semiespecializado de produção.

Resumo Objetivou-se analisar os achados hematológicos em sangue periférico e medula óssea em cães infectados por Ehrlichia spp. e Anaplasma spp.. Avaliaram-se 44 cães com suspeita clínica de hemoparasitose, de diferentes raças, idades e de ambos os sexos, submetidos ao exame sorológico pelo SNAP Test, a análises hematológicas e mielograma. Dos 44 cães avaliados, 63,6% (28/44) foram sorologicamente reagentes, sendo 57,1% (16/28) positivos para Ehrlichia spp., 21,4% (6/28) para Anaplasma spp. e 21,4% (6/28) de coinfectados. A trombocitopenia foi a alteração hematológica mais frequente em cães positivos para Ehrlichia spp., presente em 93,7% (15/16) (p=0,015) dos animais, enquanto a anemia macrocítica e hipocrômica prevaleceu em 66,7% (4/6) (p=0,010) dos animais infectados por Anaplasma spp.. Ao mielograma, 62,5% (10/16) (p=0,005) dos animais positivos para Ehrlichia spp. apresentaram hipoplasia medular e 75,0% (12/16) (p=0,044) diminuição do índice mieloide:eritroide (M:E). Nos animais positivos para Anaplasma spp., destacou-se a hiperplasia da série eritroide em 50,0% (3/6) (p=0,022) dos cães. Não houve associação significativa em nenhuma das análises com o grupo coinfecção (p>0,05). Os resultados obtidos neste estudo permitem inferir que o somatório de métodos laboratoriais é essencial na caracterização das hemoparasitoses em cães, agregando valor e permitindo uma efetiva consolidação do diagnóstico relacionado a essas doenças.

Abstract Recently, in Brazil, coloured-tegument soybean cultivars have been developed, such as those with brown and black teguments. Soybeans with black teguments have been widely used for decades due to their health benefits and their use in oriental folk medicine as a result of the presence of phytochemicals. They have been recognized as health-promoting functional food ingredients due to their antioxidant activity, and are also known to have anti-cancer, hypoglycaemic and anti-inflammatory effects and have been used in the treatment of various circulatory disorders. This study aimed to determine the proximate composition, fatty acid levels and lipoxygenase activity of soybean lineages with different tegument colours intended for human consumption. The lineage MGBR10-16601 which has a yellow tegument, presented the highest protein and lowest fat contents, with values of 37.6 g 100 g-1 and 18.3 g 100 g-1, respectively. The lineage MGBR10-16201, which also has a yellow tegument, was identified as free of lipoxygenase isoenzymes. The unsaturated fatty acid levels ranged from 18.48 to 31.37 mg g-1 and from 47.36 to 58.31 mg g-1 for oleic and linoleic acids, respectively. The lineage BRN07-50543, which has a black tegument, presented high total isoflavone levels (546 mg 100 g-1), with an oleic acid level above and linoleic acid level below the standards established by the Codex Alimentarius for soybean oil, with values of 31.37 mg g-1 and 47.36 mg g-1, respectively. The cultivar BRSMG 790A, which has a yellow tegument, presented the lowest isoflavone level (171.4 mg 100 g-1). All the genetic materials examined presented crude protein, fat, dietary fibre and ash levels within the commercial parameters established for soybeans.

Abstract The snap bean (Phaseolus vulgaris L.) is an economically important legume worldwide due to its good nutritional quality, being considered as a source of protein, fibre, vitamins and minerals. Furthermore, snap beans present high phenolic compound levels and antioxidant activity, factors that contribute in the prevention of the oxidation effects by free radicals. Hence, the present study characterized five snap bean genotypes (UEL 1, UEL 2, UEL 405, UEL 415 and Alessa) with respect to their amino acid concentrations, total phenolic compound contents and antioxidant activities. The amino acid analysis indicated that UEL 415 showed the highest glutamic acid content (12.9 g / 100 g) and UEL 2 the highest histidine content (2.27 g / 100 g). However, only the UEL 1 genotype showed the highest total phenolic compound content (0.492 mg GAE / 100 g) and highest antioxidant activity according to DPPH• radical scavenging (64.71%). The UEL 1, UEL 2 and UEL 415 genotypes presented desirable chemical characteristics for genetic improvement programmes and their commercial exploitation by food industries.
