Tribunal Constitucional Alemão: “reestruturação”?

Porque é que, do ponto de vista físico, o Tribunal Constitucional, o Supremo Tribunal de Justiça, a Procuradoria-Geral da República, a Provedoria da Justiça, entre inúmeras outras instituições nacionais, num terreno pequeno, têm que ser todas em Lisboa? (...). Aliás, v.g., “a PGR já aconselhou o Governo a levar os contratos-swap a tribunal” (Sol, 3/11/13). Abstract: Why, from the physical point of view, the Constitutional Court, the Supreme Court, the Attorney General's Office, the Office of the Ombudsman, among many other national, a small plot of land, they must all be in Lisbon? (...). Moreover, eg, "the PGR has advised the Government to take the swap contracts to court" (Sun, 11/03/13).

Selection of full-sib families of Panicum maximum Jacq under low light conditions

The silvopastoral system is a viable technological alternative to extensive cattle grazing, however, for it to be successful, forage grass genotypes adapted to reduced light need to be identified. The objective of this study was to select progenies of Panicum maximum tolerant to low light conditions for use in breeding programs and to study the genetic control and performance of some traits associated with shade tolerance. Six full-sib progenies were evaluated in full sun, 50% and 70% of light reduction in pots and subjected to cuttings. Progeny genotypic values ​​(GV) increased with light reduction in relation to plant height (H) and specific leaf area (SLA). The traits total dry mass accumulation (DM) and leaf dry mass accumulation (LDM) had GV higher in 50% shade and intermediate in 70% shade. The GV of tiller number (TIL) and root dry mass accumulation (RDM) decreased with light reduction. The highest positive correlations were obtained for the traits H and RDM with SLA and DM; the highest negative correlations were between TIL and SLA and RDM, and H and LDM. The progenies showed higher tolerance to 50% light reduction and, among them, two stood out and will be used in breeding programs. It was also found that it is not necessary to evaluate some traits under all light conditions. All traits had high broad sense heritability and high genotypic correlation between progenies in all light intensities. There is genetic difference among the progenies regarding the response to different light intensities, which will allow selection for shade tolerance

Estudo das tensões interlaminares e rotura de elementos curvos em materiais compósitos

Este trabalho aborda o comportamento mecânico de elementos curvos em materiais compósitos aquando sujeitos a forças e momentos nas extremidades. Os modos de falha mais comuns são estudados em detalhe: falha transversal na matriz devido a tensões de flexão (tensões circunferenciais), ou falha por delaminagem devido as tensões interlaminares de tracção verificadas ao longo da espessura na região curva (tensões radiais). Inicialmente, faz-se uma abordagem sobre a influência de Z-Pins na resistência interlaminar, uma abordagem sobre os efeitos de bordo, e sobre tensões interlaminares com base em teorias Layerwise de ordem superior. Salienta-se, ainda, a importância do estudo feito com o World-Wide Failure Exercise (WWFE) (Hinton et al. 2004) na comunidade científica relacionada com o tema dos materiais compósitos. O presente trabalho, é essencialmente dividido em duas partes: modelos analíticos e modelos numéricos. São estudados provetes curvos, em forma de C (semicircular), geometria analisada por Ko e Jackson (1989); e em forma de L (cantoneira de abas iguais), analisados por Sun e Kelly (1988). Começa-se por fazer uma análise teórica, através da Teoria Multicamada, ao trabalho Ko e Jackson, autores da mesma. Analisou-se também, através desta teoria, a parte em quarto de círculo da viga estudada por Sun e Kelly. Após ter a solução analítica bem compreendida, essa teoria é aplicada ao principal estudo deste trabalho, um provete semicircular, usando os empilhamentos de Sun e Kelly. É ainda estudado, e aplicado a este último, o critério de falha em três dimensões (3D) proposto por Hashin (1980). Na segunda parte, é feita uma validação numérica dos três casos anteriores, com recurso ao software comercial de elementos finitos (EF), ANSYS. Estes estudos de EF têm a diferença, relativamente aos originais, de serem em 3D, podendo assim ser retiradas todas as tensões necessárias para se aplicar o critério de falha. No final, é feita uma comparação geral entre os resultados analíticos e numéricos.

Risk factors for basal cell carcinoma: a case-control study

A controlled trial was performed with the purpose of investigating which factors could be considered of significant risk for the development of basal cell carcinoma. A total of 259 cases of basal cell carcinoma diagnosed from July 1991 to July 1992 were compared with 518 controls matched for age and sex. All subjects in both groups were white. Protocol data were submitted to statistical analysis by the chi-square test and by multiple conditional logistic regression analysis and the following conclusions were reached: 1) light skin color (types I and II of the Fitzpatrick classification), odds ratio of 2.8; outdoor work under constant sunlight, odds ratio of 5.0; the presence of actinic lesions due to exposure to the sun, odds ratio of 4.9, are risk factors perse. 2) Type III skin in the Fitzpatrick classification only represents a risk factor when the patient reports a history of intense sunburns, but not in the absence of such a history. 3) Sunburns per se do not represent a risk factor althorig the point made in item 2 of these conclusions is valid. 4) Other suspected risk factors whose significance was not confirmed by multiple conditioned logistic regression analysis were: residence in rural areas, light eyes and blond hair color, extent of the awareness of the "sun x skin cancer" relationship, familial occurrence of skin cancer, excessive exposure to the sun, and freckles appearing in childhood.

Distributed energy resource short-term scheduling using signaled particle swarm optimization

Distributed Energy Resources (DER) scheduling in smart grids presents a new challenge to system operators. The increase of new resources, such as storage systems and demand response programs, results in additional computational efforts for optimization problems. On the other hand, since natural resources, such as wind and sun, can only be precisely forecasted with small anticipation, short-term scheduling is especially relevant requiring a very good performance on large dimension problems. Traditional techniques such as Mixed-Integer Non-Linear Programming (MINLP) do not cope well with large scale problems. This type of problems can be appropriately addressed by metaheuristics approaches. This paper proposes a new methodology called Signaled Particle Swarm Optimization (SiPSO) to address the energy resources management problem in the scope of smart grids, with intensive use of DER. The proposed methodology’s performance is illustrated by a case study with 99 distributed generators, 208 loads, and 27 storage units. The results are compared with those obtained in other methodologies, namely MINLP, Genetic Algorithm, original Particle Swarm Optimization (PSO), Evolutionary PSO, and New PSO. SiPSO performance is superior to the other tested PSO variants, demonstrating its adequacy to solve large dimension problems which require a decision in a short period of time.

Finnish Kullervo and chinese martial arts stories

Introduction: There are many important Finnish plays but, due to language barrier, Finnish drama is seldom exported, particularly to Hong Kong and China.. Objective: To find out differences in mentality between the Finnish and Chinese peoples by comparing the partially localized Chinese translation of Aleksis Kivi’s tragedy, Kullervo, with genuine Chinese martial arts literature. Methodology: 1. Chapman Chen has translated the Finnish classic, Kullervo, directly from Finnish into Chinese and published it in 2005. 2. In Chen’s Chinese translation, cultural markers are domesticated. On the other hand, values, characterization, plot, and rhythm remain unchanged. 3. According to Gideon Tory, the translator has to strike a golden mean between the norms of the source language and the target language. 4. Lau Tingci lists and explicates the essential components of martial arts drama. 5. According to Ehrnrooth’s “Mentality”, equality is the most important value in Finnish culture. Findings: i. Finland emphasizes independence while China emphasizes bilateral relationships. ii. The Finnish people loves freedom, but Gai Sizung argues that the Chinese people is slavish. iii. Finns are mature while many Chinese are, according to Sun Lung-kee (“The Deep Structure of Chinese Culture”; “The Deep Structure of Chinese Sexuality”), fixated at the oral and anal stages. iv. Finnish society highly values equality while Chinese interpersonal relationships are extremely complicated and hierachical. If Kullervo were a genuine Chinese kungfu story, the plot would be much more convoluted. Conclusion: The differences between Finnish and Chinese mentalities are so significant that partially localized or adapted Chinese translations of Finnish drama may still be able to introduce Finnish culture to the Chinese audience.

Violência sexual e associação com a percepção individual de saúde entre mulheres gestantes

OBJETIVO: Estimar a prevalência de histórico de violência sexual entre mulheres gestantes e sua associação com a percepção de saúde. MÉTODOS: Estudo transversal, com 179 mulheres maiores de 14 anos e grávidas de 14 a 28 semanas, entrevistadas em serviços públicos de saúde em São Paulo, SP, entre os anos de 2006 e 2007. Os instrumentos utilizados foram: inventário de violência sexual, inventário de dados sociodemográficos e questionário de qualidade de vida relacionada à saúde: "Medical Outcomes 12-Item Short-Form Health Survey" (SF-12®). Mulheres com e sem história de violência sexual foram comparadas quanto à idade, escolaridade, ocupação, estado civil, cor da pele e autopercepção de saúde física e mental. A violência sexual foi caracterizada em penetrativa ou não penetrativa. RESULTADOS: Houve prevalência de 39,1% de violência sexual entre as entrevistadas, sendo 20% do tipo penetrativo, cometida sobretudo por agressores conhecidos. Em 57% das mulheres a primeira agressão ocorreu antes dos 14 anos. Não houve diferenças sociodemográficas entre mulheres que sofreram e as que não sofreram violência sexual. Escores médios de percepção de saúde física entre as entrevistadas com antecedente de violência sexual foram menores (42,2; DP=8,3) do que das mulheres sem este antecedente (51,0; DP=7,5) (p<0,001). A percepção de saúde mental teve escore médio de 37,4 (DP=11,2) e 48,1 (DP=10,2) (p<0,001), respectivamente para os dois grupos. CONCLUSÕES: Houve alta prevalência de violência sexual entre as grávidas dos serviços de saúde avaliados. Mulheres com antecedente de violência sexual apresentaram pior percepção de saúde do que as sem esse antecedente.

Dynamic peripheral visual performance relates to alpha activity in soccer players

Many studies have demonstrated the relationship between the alpha activity and the central visual ability, in which the visual ability is usually assessed through static stimuli. Besides static circumstance, however in the real environment there are often dynamic changes and the peripheral visual ability in a dynamic environment (i.e., dynamic peripheral visual ability) is important for all people. So far, no work has reported whether there is a relationship between the dynamic peripheral visual ability and the alpha activity. Thus, the objective of this study was to investigate their relationship. Sixty-two soccer players performed a newly designed peripheral vision task in which the visual stimuli were dynamic, while their EEG signals were recorded from Cz, O1, and O2 locations. The relationship between the dynamic peripheral visual performance and the alpha activity was examined by the percentage-bend correlation test. The results indicated no significant correlation between the dynamic peripheral visual performance and the alpha amplitudes in the eyes-open and eyes-closed resting condition. However, it was not the case for the alpha activity during the peripheral vision task: the dynamic peripheral visual performance showed significant positive inter-individual correlations with the amplitudes in the alpha band (8-12 Hz) and the individual alpha band (IAB) during the peripheral vision task. A potential application of this finding is to improve the dynamic peripheral visual performance by up-regulating alpha activity using neuromodulation techniques.

Developing Libraries Using Software Transactional Memory

Software transactional memory is a promising programming model that adapts many concepts borrowed from the databases world to control concurrent accesses to main memory (RAM) locations. This paper discusses how to support apparently irreversible operations, such as memory allocation and deallocation, within software libraries that will be used in (software memory) transactional contexts, and propose a generic and elegant approach based on a handler system, which provide the means to create and execute compensation actions at key moments during the life-time of a transaction.
