Influência das linhas genéticas na produtividade de bovinos da raça Alentejana e Mertolenga

A produtividade de um efetivo pode ser medida através da avaliação de várias características reprodutivas e produtivas. O caso presente utilizou a informação disponível referente a vacadas de raça Alentejana e Merto-lenga. A análise da influência das linhas genéticas implicou a organização dos animais em famílias de machos e em famílias de fêmeas. Analisou-se estatisticamente as características reprodutivas e produtivas. Através do programa informático MTDFREML estimou-se, para cada raça: o valor genético, direto e materno, para o peso ao desmame; o valor genético para o Intervalo entre partos e o Coeficiente de consanguinidade. Ambas as raças revelaram variabilidade genética para os caracteres em estudo, o que permitiria a seleção de futuros reprodutores, geneticamente superiores para cada caracter, originando um progresso genético dos efetivos. O coeficiente de consanguinidade na raça Alentejana foi de 5,33% e na Mertolenga de 7,12%. As linhas gené-ticas parecem não ter influenciado os caracteres em estudo; Influence of breeding lines of sires and dams on the productivity of an Alentejano and Mertolengo cattle breed population Abstract: The productivity of a cattle breed population can be measured by the evaluation of several reproductive and productive traits. The present study was based on available information about an Alentejano and Mertolengo cattle breed population. In order to analyze the influence of breeding lines, animals were organized in groups of sires and dams families. The productive and reproductive traits were statistically analyzed. Through the software package MTDFREML, the direct and maternal genetic effects for the weaning weight, genetic effect for the calving interval as well as the inbreeding were estimated for each breed. Both breeds showed genetic variability regarding the studied parameters, which would allow the selection of future breeding animals, genetically superior for each trait, resulting in a genetic progress of the herds. For the Alentejano breed, the inbreeding was 5,33% and for the Mertolengo 7,12%. The genetic lines seem to have not influenced the traits under study

Escrever para aprender estudo do meio

Tese de doutoramento, Educação (Formação de Professores), Universidade de Lisboa, Instituto de Educação, 2019Este estudo tem como objetivo contribuir para a melhoria de práticas docentes através de uma abordagem integrada da didática da língua e das ciências, partindo da constatação de que escrever ao longo do currículo favorece a compreensão, e consequentemente, a aprendizagem dos alunos (Briton, 1970; Catel, 2001), tanto ao nível da área curricular em foco como ao nível da área da língua. Vários são os estudos sobre a importância da escrita no desenvolvimento da aprendizagem (Denny, 1995; Havellock, 1995; Kleiman, 1995; Michalowsky, 1994; Street, 1984), bem como a pertinência das aprendizagens nas diversas áreas curriculares, mas raros são aqueles que se debruçam sobre a escrita no currículo numa perspetiva integradora e muito menos do ponto de vista das práticas dos professores, no que diz respeito ao ensino explícito e sistemático de estratégias diversificadas e facilitadoras de escrita para aprender ao longo do Currículo. Por conseguinte, pretendeu-se, com o presente estudo, conhecer: Qual a formação considerada adequada para que os Professores do 1.º Ciclo do Ensino Básico respondam eficazmente às necessidades de escrita dos alunos para construir conhecimento na área de Estudo do Meio? Com base na investigação, seguindo a metodologia Design-Based Research, desenvolveu-se um programa de formação de professores sobre estratégias promotoras do desenvolvimento da escrita como ferramenta de aprendizagem na área de estudo do meio. O programa da formação foi concebido, em conjunto com os professores participantes, a partir de informações obtidas através de entrevistas, de inquério por questionário, de observação de aulas e de análise de produções escritas, na área de estudo do meio, por parte de alunos dos 3.º e 4.º anos de escolaridade. Ao longo das várias observações realizadas, em paralelo com o decorrer da Oficina de Formação, verificou-se que, em simultâneo, enquanto os professores alteravam as suas práticas, de forma progressiva, os alunos foram começando a fazer uso das estratégias apresentadas pelos seus professores e, como consequência, o desempenho dos alunos melhorou nas áreas em intervenção. Ou seja, as aprendizagens dos alunos foram evoluindo quer ao nível da escrita, quer ao nível do estudo do meio, a partir da alteração de práticas dos seus professores.Based on the observation that writing across the curriculum promotes comprehension, and consequently, student’s learning (Briton, 1970; Catel, 2001), both in therms of the curricular areas that serves as a subject and in the área of language, this study has as an objective to contribute to the improvement of teaching practices through an integrated teaching approach. There are several studies about the importance of writing in the development of learning, as well as the pertinence of learning in the diferente curricular áreas, but there are few studies that deal with writing in the curriculum in na integrative perspective, much less in the perspective of the practices of the teachers with regard to the explicit and systematic teaching of diversified and facilitating writing strategies for learning across the curriculum. Therefore, it was intended, with the presente study, to know: What training is considered adequate for teachers of the 1st cycle of Basic Education to respond effectively to the writing needs of students to build knowledge in sciences? Based on research carried out in the Design-Based Research modality, it was sought to provide teachers in the 1st Cycle of Basic Education, to teach in classes of 4th year, a training on strategies promoting the development of writing as a tool for learning sciences and to propose them to their students in the effective development of this competence. The training program was, together with the participating teachers, conceived from the information obtained initially, through interviews, questionnaires, direct observation of the classes and analysis of written productions, in sciences, students of the 3rd and 4th year of schooling. The implementation of the program was constituted by cycles through which it was tried to perfect the previous one based on the findings, reflections, suggestions of who applied it. With this, it was intended to make an importante contribution to the development of the practices of the teachers who constituted the group and formulate guidelines to take into account whwn developing integrated didactic practices. Throught the several observations made in parallel with the course of Training Workshop, it was found that, in a progressive way, the students were beginning to make use of the strategies presented by their teachers, spontaneously. That is, the changes in the students’practices were occurring from the change in teachers’practices

NDVI and LST extraction of MODIS data under a GIS open source application - Rickettsia study case in Angola

Fevers of unknown origin can have different aetiologies. The overlapping symptomatology of rickettsial infection and other endemic diseases that cause fever leads to a misdiagnosis or under-diagnosis of spotted fever group of Rickettsia (SFGR). To better understand the epidemiology of this vector-borne disease in Angola, a comprehensive seroprevalence study was conducted investigating the exposure to SFGR in a sample of 92 febrile, Malaria and Yellow Fever negative human plasma specimen, collected to the study of the national surveillance of febrile syndromes between 2016 and 2017, in Angola. The seroprevalence of IgG antibodies against SFG Rickettsia in humans was calculated by gender, and aimag (province). All data were analyzed through a logistic regression. Spatial data sources included Normalized Differential Vegetation Index (NDVI) and Land Surface Temperature (LST) products by Moderate Resolution Imaging Spectroradiometer (MODIS). The main objective of this work was the development of a GIS open source application to automatize the extraction of LST and NDVI products from MODIS images. The application was created as a simple graphic interface composed by two input fields (the text file with the coordinates of the sampling points (in sinusoidal coordinate system and the folder with the MODIS images), the field to define the buffer distance, and the output file. The application was tested considering MOD11A1 (LST product), MOD13Q1 and MYD13Q1 (NDVI product), free download from the USGS. QGIS 2.18.17 was used for geospatial operations and Python language was employed for the development of the GIS open source application under QGIS software. The process includes the circumscription of the major clusters where human data were collected. Then, a convex hull (minimum convex bounding geometry) was created around each sampling site with a 10 km buffer zone to accommodate the mobility among the nomadic people being samples. Counts of seropositive and seronegative humans were calculated within each of these sampling clusters along with the mean, maximum, and minimum values of NDVI and LST, and percent area of each land cover class. The application was tested in a set of 92 points in Angola and a buffer of 10 km considering the Universal transverse Mercator (UTM) Zone 33S projection (EPSG:32733) was applied for each point. The LST and NDVI statistical values were extracted for each sampling cluster. Variations in ecological niches, abundance of vegetation and land surface temperature, for ticks and fleas between different provinces could be in part responsible for the geographic differences in seroprevalence observed with SFGR

Molecular detection of Rickettsia spp. in ticks and fleas collected from rescued hedgehogs (Erinaceus europaeus) in Portugal.

Hedgehogs (e.g., Erinaceus europaeus, E. roumanicus) are wild mammals that frequently are observed near residential areas. The aim of this study was to investigate ticks and feas collected from European hedgehogs in Portugal and to evaluate the prevalence of Rickettsia in those ectoparasites. Ticks and feas were identifed by morphological and molecular methods, and molecular detection by PCR and genotypic characterization of Rickettsia spp. was performed targeting ompB, ompA and gltA gene fragments. In total, 1892 ticks and 213 feas were collected from 33 rescued European hedgehogs captured in seven districts of the north and centre of Portugal. Two tick species were identifed – Rhipicephalus sanguineus accounted for 91% (n=1719) of the total ticks collected and 9% (n=173) were Ixodes hexagonus. All feas were identifed as Archaeopsylla erinacei. Regarding pathogen detection, Rickettsia massiliae DNA was found in 22 of the 212 tested Rh. sanguineus. None of the 48 I. hexagonus tested showed to be positive for rickettsiae. Rickettsia asembonensis DNA was identifed in 55 A. erinacei feas tested (n=117). These results show that European hedgehogs are exposed to R. massiliae transmitted by ticks and to R. asembonensis via feas suggesting that these mammals might be involved in the natural transmission cycle of these Rickettsia species. This study is the frst report of R. asembonensis in feas in Portugal.A91F-E8B8-FA62 | Teresa Susana Letra MateusN/

Molecular detection of human pathogenic gastric helicobacter species in wild rabbits (Oryctolagus cuniculus) and Wild Quails (Coturnix coturnix)

Wildlife plays a major role in the maintenance and transmission of multihost pathogens. Several Helicobacter spp. have been described to have zoonotic potential; thus, human, domestic and wild animal interactions deserve more attention. In this study, the presence of the DNA of human pathogenic gastric Helicobacter species was determined in gastric samples collected from wild rabbits and wild quails during the national hunting campaigns in Portugal. Eleven out of the 12 wild rabbits (91.7%) and all six wild quails tested (100%) were PCR positive for one or more gastric Helicobacter species. In both animal species, H. felis, H. bizzozeronii and H. salomonis DNA were detected. In addition to these non-Helicobacter pylori Helicobacter spp. (NHPH), H. pylori DNA was also identified in gizzard samples of wild quails. These findings might indicate that wild rabbits and wild quails may act as reservoirs and contribute to the H. pylori and NHPH environment dissemination, causing both Public Health and One health concerns to ariseA91F-E8B8-FA62 | Teresa Susana Letra MateusN/

A 2-Year Longitudinal Seroepidemiological Evaluation of Toxoplasma gondii Antibodies in a Cohort of Autochthonous Sheep from Central Portugal

Background: Toxoplasma gondii is an important zoonosis and one of the major causes of abortion in sheep worldwide. (2) Methods: We performed a 2-year longitudinal serological antiT. gondii IgG screening on a cohort of a spatially confined population of a Portuguese autochthonous sheep breed in central Portugal. (3) Results: From the screening of the 2015 and 2016 sera, an increase of seroprevalence was observed (57.7% (95% CI: 49.9–65.3%) versus 69.1% (95% CI: 61.5–75.9), from 2015 and 2016, respectively) (p = 0.031). (4) Conclusions The present study is the first to provide prospective data on the anti-T. gondii serological status of a sheep cohort in Portugal, showing an increase in the occurrence of T. gondii. There is a need to provide a clearer understanding of T. gondii epidemiology in Portugal, ideally by implementing monitoring programs on sentinel herds, not only due to the high impact of T. gondii on animal health but also for it being a zoonosis.info:eu-repo/semantics/publishedVersio

Registo Oncológico na Região Autónoma da Madeira, 2017

Prefácio O Registo Oncológico Nacional (RON) encontra-se unificado e reorganizado desde o dia 1 de Janeiro de 2018, com a entrada em vigor da nova legislação - Lei n.º 53/2017 Diário da República n.º 135/2017, Série I de 2017-07-14. Previamente à data referida, o registo dos casos de doença oncológica efetuava-se em quatro plataformas principais, de acordo com a área geográfica: ROR-Sul (na qual se inseria o registo da Região Autónoma da Madeira - RAM); ROR-Centro; RORENO e RORA (Açores). Com a nova metodologia e a plataforma única nacional, a RAM assistiu a uma reorganização do seu registo, com um novo grupo de trabalho e uma nova dinâmica. Partindo de recursos humanos experientes e com dedicação de várias décadas a este projeto, conseguimos instruir novos elementos promovendo um registo organizado, atualizado e de qualidade. O grupo do registo oncológico da RAM pretende contribuir para o aumento da atividade científica não assistencial da instituição e da região que representa. A publicação dos dados aferidos e a sua disponibilização permitirão a discussão entre os profissionais de saúde envolvidos no rastreio, na prevenção, no diagnóstico, no tratamento e nos cuidados de suporte ao doente oncológico. A presente publicação tem como objetivo principal proceder ao tratamento estatístico dos dados aferidos da plataforma do RON referente aos novos casos de doença oncológica na RAM, no ano de 2017. A divulgação do padrão de distribuição dos tumores malignos na população madeirense vai possibilitar aumentar o conhecimento sobre as neoplasias mais frequentes, as faixas etárias mais afetadas, as taxas de incidência totais e padronizadas, entre outros aspetos. Só com esse conhecimento se poderá constituir uma base de trabalho entre os profissionais e as instâncias governativas, que visa a melhoria das políticas e da prestação de cuidados de saúde ao doente oncológico da RAM. No futuro próximo, pretende-se que a rede organizativa e a qualidade de registo seja ampliada e de maior abrangência no que se refere às instituições de domínio privado na RAM. O registo oncológico da RAM agradece a todos os profissionais envolvidos no tratamento da doença oncológica que, de forma direta ou indireta, contribuíram para a elaboração deste trabalho, salientando que a qualidade do registo do processo clínico do doente é fulcral para o adequado conhecimento da doença oncológica na região.info:eu-repo/semantics/publishedVersio
