Relatório de estágio de atividade física e desporto realizado no Club Sport Marítimo

O presente relatório, visa relatar todo o trabalho desenvolvido ao longo do estágio curricular, realizado no Club Sport Marítimo, tendo como objetivo a conclusão do Mestrado em Atividade Física e Desporto, ministrado na Universidade da Madeira. A principal atividade abordada ao longo do estágio curricular foi o projeto Marítimo LAB, cujo principal objetivo é a avaliação e a potencialização das capacidades individuais e coletivas dos jovens atletas do futebol de formação do Clube. A avaliação dos atletas baseouse na aplicação das baterias de teste e os momentos de potencialização na aplicação de unidades de treino com o intuito de estimular e aperfeiçoar as capacidades individuais. A amostra foi constituída por 241 atletas, todos do género masculino, com idades compreendidas entre os 10 e os 18 anos de idade. Para uma análise das variáveis da composição corporal e da performance motora, efetuou-se uma comparação dos valores médios dos três momentos de avaliação, com a finalidade de verificar o grau de evolução dos atletas ao longo de uma época competitiva. Para além do projeto Marítimo LAB, o estagiário também foi integrado numa equipa técnica do escalão de iniciados (Sub-15), e esteve presente em todas atividades organizadas e dinamizadas pelo departamento de futebol amador do Clube.

On-line learning in radial basis functions networks

An analytic investigation of the average case learning and generalization properties of Radial Basis Function Networks (RBFs) is presented, utilising on-line gradient descent as the learning rule. The analytic method employed allows both the calculation of generalization error and the examination of the internal dynamics of the network. The generalization error and internal dynamics are then used to examine the role of the learning rate and the specialization of the hidden units, which gives insight into decreasing the time required for training. The realizable and over-realizable cases are studied in detail; the phase of learning in which the hidden units are unspecialized (symmetric phase) and the phase in which asymptotic convergence occurs are analyzed, and their typical properties found. Finally, simulations are performed which strongly confirm the analytic results.

A tudás termelői? Az Európai Unió kormányainak és nagyvállalatainak hozzájárulása a tudásgazdaság létrehozásához

Az 1990-es évek eleje óta tudományos értekezések és kormányzati tervezetek szerzői egyre inkább a tudásban, annak létrehozásában, használatában és cseréjében vélik felismerni a gazdasági növekedés és társadalmi fejlődés legfontosabb forrását. Mindezek ellenére az európai nagyvállalatok innovációs, kutatási-fejlesztési aktivitása, kutatási-fejlesztési költségvetése nem tükrözi ezt a felismerést. Ugyanez vonatkozik az Európai Unió és a tagállamok kormányainak politikai nyilatkozataira is: csaknem tíz évvel a Lisszaboni Stratégia meghirdetése és évről évre történő megerősítése után az EU-tagállamok többsége nem tudott érdemleges előrelépést tenni az innováció, a kutatás-fejlesztés terén. Az Európai Uniónak nemhogy nem sikerült "a világ legversenyképesebb és legdinamikusabb tudásalapú gazdaságává válnia", de az elmúlt tíz év során tovább mélyült az innovációs szakadék az Európai Unió tagállamai és a globális gazdaság leginnovatívabb országai között.

Queering Human Resource Development

Societal norms for gender and sexual identity and practices tend to be heteronormative or homonormative, often privileging individuals belonging to the normative population. Viewing human resource development through a queer lens can suggest ways to support work environments that welcome all identities.

Advertising Legalized Gambling: A Late Bloomer Under the First Amendment

New federal laws and court cases have put a new perspective on the ability of the industry to advertise as it has never been able to do before. With gaming becoming more prevalent, the acceptability of the legal industry is making promotion easier. The author discusses these new influences.

New Organogermanium Substrates for Palladium-Catalyzed Cross-Coupling Reactions. Application of Organogermanes towards the Synthesis of Carbon-5 Modified Uridine Analogues

The diverse biological properties exhibited by uridine analogues modified at carbon-5 of the uracil base have attracted special interest to the development of efficient methodologies for their synthesis. This study aimed to evaluate the possible application of vinyl tris(trimethylsilyl)germanes in the synthesis of conjugated 5-modified uridine analogues via Pd-catalyzed cross-coupling reactions. The stereoselective synthesis of 5-[(2-tris(trimethylsilyl)germyl)ethenyl]uridine derivatives was achieved by the radical-mediated hydrogermylation of the protected 5-alkynyluridine precursors with tris(trimethylsilyl)germane [(TMS)3GeH]. The hydrogermylation with Ph3GeH afforded in addition to the expected 5-vinylgermane, novel 5-(2-triphenylgermyl)acetyl derivatives. Also, the treatment with Me3GeH provided access to 5-vinylgermane uridine analogues with potential biological applications. Since the Pd-catalyzed cross-coupling of organogermanes has received much less attention than the couplings involving organostannanes and organosilanes, we were prompted to develop novel organogermane precursors suitable for transfer of aryl and/or alkenyl groups. The allyl(phenyl)germanes were found to transfer allyl groups to aryl iodides in the presence of sodium hydroxide or tetrabutylammonium fluoride (TBAF) via a Heck arylation mechanism. On the other hand, the treatment of allyl(phenyl)germanes with tetracyanoethylene (TCNE) effectively cleaved the Ge-C(allyl) bonds and promoted the transfer of the phenyl groups upon fluoride activation in toluene. It was discovered that the trichlorophenyl,- dichlorodiphenyl,- and chlorotriphenylgermanes undergo Pd-catalyzed cross-couplings with aryl bromides and iodides in the presence of TBAF in toluene with addition of the measured amount of water. One chloride ligand on the Ge center allows efficient activation by fluoride to promote transfer of one, two or three phenyl groups from the organogermane precursors. The methodology shows that organogermanes can render a coupling efficiency comparable to the more established stannane and silane counterparts. Our coupling methodology (TBAF/moist toluene) was also found to promote the transfer of multiple phenyl groups from analogous chloro(phenyl)silanes and stannanes.

Vertical profiles of environmental parameters measured on discrete water samples collected with Niskin bottles at station TARA_144 during the Tara Oceans expedition 2009-2013

The Tara Oceans Expedition (2009-2013) was a global survey of ocean ecosystems aboard the Sailing Vessel Tara. It carried out extensive measurements of evironmental conditions and collected plankton (viruses, bacteria, protists and metazoans) for later analysis using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set includes properties of seawater, particulate matter and dissolved matter that were measured from discrete water samples collected with Niskin bottles during the 2009-2013 Tara Oceans expedition. Properties include pigment concentrations from HPLC analysis (10 depths per vertical profile, 25 pigments per depth), the carbonate system (Surface and 400m; pH (total scale), CO2, pCO2, fCO2, HCO3, CO3, Total alkalinity, Total carbon, OmegaAragonite, OmegaCalcite, and dosage Flags), nutrients (10 depths per vertical profile; NO2, PO4, N02/NO3, SI, quality Flags), DOC, CDOM, and dissolved oxygen isotopes. The Service National d'Analyse des Paramètres Océaniques du CO2, at the Université Pierre et Marie Curie, determined CT and AT potentiometrically. More than 200 vertical profiles of these properties were made across the world ocean. DOC, CDOM and dissolved oxygen isotopes are available only for the Arctic Ocean and Arctic Seas (2013).

Uso da cinza do bagaço da cana-de-açúcar como matéria-prima na substituição dos fundentes para aplicações em porcelanato

The present study aims to evaluate the potential use of bagasse ash from sugar cane (CBC) as a flux, replacing phyllite and/or feldspar in standard industrial mass production of enameled porcelain, verifying the possibility of the CBC contribute to the overall reduction of the coefficient of thermal expansion of the ceramic mass. To this end, as a result of the research, we characterized the raw material components of the standard mass (clay, phyllite, kaolin, feldspar, quartz and talc) and the residue of BCC, by testing by XRF, XRD, AG, DTA and ATG. Specimens (CDP) were manufactured in the dimensions of 100 mm x 50 mm x 8 mm in uniaxial matrix under compaction pressure of 33 MPa, assembled in batches of 3 units subsequently sintered at temperatures of 1150°C to 1210°C by varying the Rating Scale at 10°C, heating and cooling ramp of 50°C/min and 25°C/min, with levels of 1 min, 3 min, 5 min, 8 min, 10 min, 15 min, 30 min and 60 min. analyzing the results of the physical properties of water absorption (WA), linear firing shrinkage (LFS), dilatometric analysis (DTA), flexural strain (SFT) and SEM of the sintered bodies in order to verify the adequacy of CDP to ISO 13006, ISO 10545, NBR 13816 standards; NBR 13817 and NBR 13818. The study showed that the formulations that best suit the requirements of the standards are:. G4 - which was applied in 10% of replacing the CBC phyllite, sintering temperature 1210 ° C for 10 min and porch, and F3 - with application of 7.5% of CBC to replace the feldspar in the sintering temperatures of 1190°C, 1200°C and 1210°C for 10 min and porch. These formulations showed better performance regarding the formation of primary and secondary mullite, with considerable reduction of cracks and pores, meeting the prerequisites of standards for glazed porcelain. The results shows that the use of the CBC as a flux in the preparation of porcelain mass meets standard parameters for the manufacture of the product, and thereby can reduce environmental impact and the cost of production. Therefore, it is recommended to use this residue in the ceramics industry, due to its industrial, commercial and collaborative viability for sustainability.
