This article examines China's proposals on the reform of global governance, and discusses the main features of China's proposing behavior in the cases of the WTO Doha Round negotiation and G-20 Process. The main findings are: (1) in the critical junctures of global governance reform, China engaged the reform of the global governance institutions proactively, and put forward a series of reform proposals; (2) in proposing behavior, China argued the global governance institutions should be properly adjusted without intention to change the basic principles, refrained from playing a leadership role while proposing jointly with other countries, and upheld the principled idea of pro-development.

Pilosocereus aurisetus é uma espécie de cactos de importância econômica e ambiental que se encontra em risco de extinção. A propagação em áreas naturais ocorre, principalmente, de forma sexuada; entretanto, não há registro da germinação e viabilidade de sementes e morfologia pós-seminal de plântulas dessa espécie. Assim, objetivou-se avaliar a germinação de sementes e descrever a morfologia do desenvolvimento pós-seminal de plântulas de P. aurisetus. Para isso, sementes, armazenadas em condições ambientais por 19 meses, foram submetidas aos tratamentos: embebição em água por 24 horas; pré-resfriamento; imersão em solução de giberelina, nas concentrações de 250 mg L-1 e 500 mg L-1; e um tratamento controle. As sementes foram colocadas para germinar em meio de cultura MS, por 30 dias, quando se avaliou a percentagem de germinação. O delineamento estatístico foi o inteiramente casualizado, com cinco tratamentos e quatro repetições, sendo dispostas 25 sementes por parcela. A caracterização pós-seminal foi realizada por um período de 60 dias, utilizando-se microscópio binocular, com base nas Regras para Análise de Sementes. Maior percentagem da germinação de sementes ocorreu no controle, ou quando embebidas por 24 horas, sendo observados 90% e 83%, respectivamente. A morfologia do desenvolvimento pós-seminal indicou que a germinação é do tipo epígea, com hipocótilo de reserva; suas plântulas sofrem modificações na região do colo, para a emissão de raízes, e apresentam cerdas no ápice caulinar, mesmo na fase inicial da expansão cotiledonar. A diferenciação e início da formação das costelas iniciam-se aos 60 dias após a germinação, com o desenvolvimento do epicótilo.

Será que tem sentido do ponto de vista constitucional criminalizar o lenocínio? E porque não regulamentar nomeadamente através do pagamento de impostos e tributos? § Does it make sense from a constitutional point of view criminalize pimping? And why not regulate in particular through the payment of taxes and duties?

Education for health is a process in which all public health and medical care personnel are involved. People learn both formally (planned learning experiences) and informally (unplanned learning experiences). Since the patient, the client, the consummer and the community expect public health and medical care personnel to assist them with health and disease issues and problems, the response of the professional "educates" the customer whether the professional intends to educate or not. Therefore, it is incumbent on all public health and medical care professionals to understand their educational functions and their role in health education. It is also important that the role of the specialist in education be clear. The specialist, as to all other specialists, has an in-depth knowledge of his area of expertise, i.e., the teaching/learning process; s/he may function as a consultant to others to enhance the educational potential of their role or s/he may work with a team or with communities or groups of patients. Specific competencies and knowledge are required of the health education specialist; and there is a body of learning and social change theory which provides a frame of reference for planning, implementing and evaluating educational programs. Working with others to enhance their potential to learn and to make informed decisions about health/disease issues is the hallmark of the health education specialist.

We calculate the equilibrium thermodynamic properties, percolation threshold, and cluster distribution functions for a model of associating colloids, which consists of hard spherical particles having on their surfaces three short-ranged attractive sites (sticky spots) of two different types, A and B. The thermodynamic properties are calculated using Wertheim's perturbation theory of associating fluids. This also allows us to find the onset of self-assembly, which can be quantified by the maxima of the specific heat at constant volume. The percolation threshold is derived, under the no-loop assumption, for the correlated bond model: In all cases it is two percolated phases that become identical at a critical point, when one exists. Finally, the cluster size distributions are calculated by mapping the model onto an effective model, characterized by a-state-dependent-functionality (f) over bar and unique bonding probability (p) over bar. The mapping is based on the asymptotic limit of the cluster distributions functions of the generic model and the effective parameters are defined through the requirement that the equilibrium cluster distributions of the true and effective models have the same number-averaged and weight-averaged sizes at all densities and temperatures. We also study the model numerically in the case where BB interactions are missing. In this limit, AB bonds either provide branching between A-chains (Y-junctions) if epsilon(AB)/epsilon(AA) is small, or drive the formation of a hyperbranched polymer if epsilon(AB)/epsilon(AA) is large. We find that the theoretical predictions describe quite accurately the numerical data, especially in the region where Y-junctions are present. There is fairly good agreement between theoretical and numerical results both for the thermodynamic (number of bonds and phase coexistence) and the connectivity properties of the model (cluster size distributions and percolation locus).

We derive a set of differential inequalities for positive definite functions based on previous results derived for positive definite kernels by purely algebraic methods. Our main results show that the global behavior of a smooth positive definite function is, to a large extent, determined solely by the sequence of even-order derivatives at the origin: if a single one of these vanishes then the function is constant; if they are all non-zero and satisfy a natural growth condition, the function is real-analytic and consequently extends holomorphically to a maximal horizontal strip of the complex plane.

A two terminal optically addressed image processing device based on two stacked sensing/switching p-i-n a-SiC:H diodes is presented. The charge packets are injected optically into the p-i-n sensing photodiode and confined at the illuminated regions changing locally the electrical field profile across the p-i-n switching diode. A red scanner is used for charge readout. The various design parameters and addressing architecture trade-offs are discussed. The influence on the transfer functions of an a-SiC:H sensing absorber optimized for red transmittance and blue collection or of a floating anode in between is analysed. Results show that the thin a-SiC:H sensing absorber confines the readout to the switching diode and filters the light allowing full colour detection at two appropriated voltages. When the floating anode is used the spectral response broadens, allowing B&W image recognition with improved light-to-dark sensitivity. A physical model supports the image and colour recognition process.

We investigate the crust, upper mantle and mantle transition zone of the Cape Verde hotspot by using seismic P and S receiver functions from several tens of local seismograph stations. We find a strong discontinuity at a depth of similar to 10 km underlain by a similar to 15-km thick layer with a high (similar to 1.9) Vp/Vs velocity ratio. We interpret this discontinuity and the underlying layer as the fossil Moho, inherited from the pre-hotspot era, and the plume-related magmatic underplate. Our uppermost-mantle models are very different from those previously obtained for this region: our S velocity is much lower and there are no indications of low densities. Contrary to previously published arguments for the standard transition zone thickness our data indicate that this thickness under the Cape Verde islands is up to similar to 30 km less than in the ambient mantle. This reduction is a combined effect of a depression of the 410-km discontinuity and an uplift of the 660-km discontinuity. The uplift is in contrast to laboratory data and some seismic data on a negligible dependence of depth of the 660-km discontinuity on temperature in hotspots. A large negative pressure-temperature slope which is suggested by our data implies that the 660-km discontinuity may resist passage of the plume. Our data reveal beneath the islands a reduction of S velocity of a few percent between 470-km and 510-km depths. The low velocity layer in the upper transition zone under the Cape Verde archipelago is very similar to that previously found under the Azores and a few other hotspots. In the literature there are reports on a regional 520-km discontinuity, the impedance of which is too large to be explained by the known phase transitions. Our observations suggest that the 520-km discontinuity may present the base of the low-velocity layer in the transition zone. (C) 2011 Elsevier B.V. All rights reserved.

O presente trabalho foi realizado no âmbito de um estágio curricular, em parceria com o Instituto de Formação Aeronáutica, tendo como tema a “Certificação de uma Parte M completa (Subparte G + F) para Aviação Geral”. Note-se que quando o autor faz referência à aviação geral, dirige-se às aeronaves não envolvidas no transporte aéreo comercial e cuja massa máxima à descolagem é inferior ou igual a 5700 kg. No entanto no desenrolar da elaboração deste trabalho, o IFA optou pela obtenção da certificação de acordo com a Parte 145, o que permitirá a realização de manutenção no âmbito da aviação comercial e geral, o que torna irrazoável a certificação apenas de acordo com a Parte M Subparte F, já que esta se direcciona única e exclusivamente para a aviação geral. Por conseguinte, o autor optou por desenvolver e abordar apenas a certificação de acordo com a Parte M Subparte G. Com efeito, como principal objectivo pretende-se elaborar um Manual de Gestão da Continuidade da Aeronavegabilidade, por forma a criar as condições necessárias para certificar uma nova empresa, vulgo “start-up”, a ser incubada no IFA, como uma Organização de Gestão da Continuidade da Aeronavegabilidade de acordo com a Parte M Subparte G. O referido manual permitirá demonstrar perante a Autoridade Aeronáutica que a empresa em apreço preenche os requisitos exigidos e definidos na Regulamentação aplicável. Mais se pretende com este trabalho trazer benefícios para a nova empresa a incubar no IFA, designadamente acelerar todo o processo de formação e permitir que a mesma se possa inserir no mercado com a maior brevidade possível. Importa ainda realçar que o trabalho desenvolvido implicou o levantamento e a análise minuciosa de toda a Legislação e Regulamentação relacionada com a Continuidade da Aeronavegabilidade de aeronaves e seus componentes.
