China's space program : a new tool for PRC "soft power" in international relations?

When China launched an anti-satellite (ASAT) weapon in January 2007 to destroy one of its inactive weather satellites, most reactions from academics and U.S. space experts focused on a potential military “space race” between the United States and China. Overlooked, however, is China’s growing role as global competitor on the non-military side of space. China’s space program goes far beyond military counterspace applications and manifests manned space aspirations, including lunar exploration. Its pursuit of both commercial and scientific international space ventures constitutes a small, yet growing, percentage of the global space launch and related satellite service industry. It also highlights China’s willingness to cooperate with nations far away from Asia for political and strategic purposes. These partnerships may constitute a challenge to the United States and enhance China’s “soft power” among key American allies and even in some regions traditionally dominated by U.S. influence (e.g., Latin America and Africa). Thus, an appropriate U.S. response may not lie in a “hard power” counterspace effort but instead in a revival of U.S. space outreach of the past, as well as implementation of more business-friendly export control policies.

Water relations in physic nut according to climatic seasonality, in semiarid conditions

The objective of this work was to determine the effect of climatic seasonality on physic nut (Jatropha curcas), in field, under semiarid climate conditions. Stomatal conductance (g s), transpiration (E), soluble leaf carbohydrates (SLC), free amino acids (FAA) and total proteins (TP) were measured in leaves, in a commercial plantation in Northeast Brazil, during the summer and autumn. Plants showed high g s and E, as well as SLC, FAA and TP contents in the summer, which gradually decreased with the lower temperatures and photosynthetically active radiation during the autumn, despite the higher water availability. Even in conditions of adequate water availability, the combination of low temperatures and reduced light drastically decreased foliar metabolism.

Morphometric and allometric relations of cage-reared Iguaçu surubim

The objective of this work was to evaluate the morphometric and allometric relations of Iguaçu surubim (Steindachneridion melanodermatum) cultivated in net cages. One hundred and twenty specimens were cultivated at a density of 50 fish per square meter in three 6 m³ net cages. Fish were fed three times a day with commercial feed. Thirty fish were evaluated at 60, 120, 180, and 360 days of cultivation as to the variables: total body, head, clean trunk, viscera, skin, and fin weight; total, standard, and head length; and head and body height. The Iguaçu surubim shows later development of the clean trunk and early development of the other body parts.

Some advances in mathematical models for preference relations

Preference relations, and their modeling, have played a crucial role in both social sciences and applied mathematics. A special category of preference relations is represented by cardinal preference relations, which are nothing other than relations which can also take into account the degree of relation. Preference relations play a pivotal role in most of multi criteria decision making methods and in the operational research. This thesis aims at showing some recent advances in their methodology. Actually, there are a number of open issues in this field and the contributions presented in this thesis can be grouped accordingly. The first issue regards the estimation of a weight vector given a preference relation. A new and efficient algorithm for estimating the priority vector of a reciprocal relation, i.e. a special type of preference relation, is going to be presented. The same section contains the proof that twenty methods already proposed in literature lead to unsatisfactory results as they employ a conflicting constraint in their optimization model. The second area of interest concerns consistency evaluation and it is possibly the kernel of the thesis. This thesis contains the proofs that some indices are equivalent and that therefore, some seemingly different formulae, end up leading to the very same result. Moreover, some numerical simulations are presented. The section ends with some consideration of a new method for fairly evaluating consistency. The third matter regards incomplete relations and how to estimate missing comparisons. This section reports a numerical study of the methods already proposed in literature and analyzes their behavior in different situations. The fourth, and last, topic, proposes a way to deal with group decision making by means of connecting preference relations with social network analysis.

Supervisor-Student Relations: Examining the Spectrum of Conflicts of Interest in Bioscience Laboratories

Much attention has been given to financial conflicts of interest (COI) in bioscience research. Yet to date, surprisingly little attention has focused on other COIs that arise in supervisor-student relations. We examine a spectrum of related situations, ranging from standard graduate supervision through to dual relationships sometimes found in research with commercial potential. We illustrate some of the less-obvious factors that can bias supervisory judgment, and situate financial COI along a spectrum of forces that are deserving of recognition. We conclude by providing two sets of recommendations: one for individual supervisors, and the other for institutions and policy-makers.

L'arbitrage commercial international et les garanties procédurales

Cette recherche aborde un sujet complexe, qui est en plein débat doctrinal en droit de l'arbitrage international: L'arbitrage commercial international et les garanties procédurales. Au fait, l'arbitrage commercial international revêt le mode traditionnel des règlements de litiges du commerce international et des relations économiques internationales. À cause de l'hybridité de sa nature (contractuelle et juridictionnelle), il est le plus souvent préféré par les parties aux tribunaux étatiques. Cette faveur vis-à-vis de ce mode de règlements de litiges internationaux s'explique par le développement de l'économie internationale, par la globalisation du marché, par la conclusion de nombreuses conventions internationales en la matière, par la création des centres d'arbitrage, enfin par la modernisation des lois et règlements nationaux. En revanche, il est constaté que l'arbitrage souffre d'un déficit de prévisibilité et de certitudes pour les acteurs du commerce international. Que l'on songe seulement à la multiplication des rattachements législatifs et des contrôles judiciaires: conflits de lois, conflits entre les règles de conflits, etc. Nous avons démontré que la solution aux difficultés de la méthode conflictualiste serait l'harmonisation de la procédure arbitrale internationale et que ce mode de règlement de différends débouche de plus en plus sur le rapprochement entre traditions juridiques différentes (Common Law et droit civil).Toutefois, ce mouvement de convergence est loin d'être achevé. Beaucoup d'autres pratiques arbitrales continuent de garder l'empreinte de la diversité des procédures étatiques et celle des grands systèmes juridiques mondiaux.

It will be succesful to have a commercial relation between France and Colombia focus on the milk sector ?

Globalization has led to a drastic change on the international trade, this has caused that many countries such as France and Colombia find new business partners. This is the raison because I develop the investigation about How these countries can be integrated commercially in the dairy sector? Colombia and France had active trade relations for more than 8 years, but this has been declining for several factors. In the case of France, it has found that Germany is an excellent producer of raw milk, which can supply domestic demand and can export large quantities with a low price to European countries because of its proximity. For this reason, Colombia is a country that can not compete with Germany directly in raw milk, but I concluded that Colombia could become a major competitor with organic milk. This is the result of a research of the way they raise and feed the cows in the two countries, Colombia is generally on open country and Germany is on cow housing. In Colombia, the country found that Venezuela could offer many benefits in the processing of raw milk, and other processes that require high technology. But today Colombia has had several disputes with Venezuela and many Colombian companies are affected in this sector. Additionally, France is one of the largest producers and distributors of processed milk and its derivatives; it launches annually many manufactured products with high technology. At this point, Colombia can take out the best advantage because it can create an strategic alliance with French companies to bring most innovative and processed products such as cheese and yoghurts. The theoretical framework of this thesis consists on the analysis of competitiveness, because it is relevant to see if these two countries are competitive or if one has the comparative advantage over the other. The related authors are: Michael Porter, Adam Smith and David Ricardo. To complete the theoretical part, we found that France has a comparative advantage over Colombia in this sector thanks to its high technology, and Colombia is not currently competitive in the area of raw milk because the milk price is higher and the distance is a barrier, and it has no technology. But this research indicates that Colombia could become a competitive country selling organic milk.

Glutathione Peroxidase 1 Pro198Leu Polymorphism in Brazilian Alzheimer's Disease Patients: Relations to the Enzyme Activity and to Selenium Status

Background/Aims: Oxidative stress plays a central role in Alzheimer's disease (AD). Pro198Leu cytosolic glutathione peroxidase (GPx1) polymorphism seems to be associated with a lower activity of this enzyme, but there are no studies with AD patients. Thus, the aim was to determine the frequency of the GPx1 Pro198Leu polymorphism in AD patients and to verify its relation to glutathione peroxidase (GPx) activity and selenium (Se) status. Methods:The study was carried out in a group of AD elderly (n = 28) compared to a control group (n = 29). Blood Se concentrations were measured through hydride generation atomic absorption spectroscopy. GPx activity was determined using a commercial kit, and the polymorphism using amplified DNA sequencing. Results:The distribution of genotypes was not different between groups. The variant allele frequency was 0.179 (AD group) and 0.207 (control group). Although no differences regarding GPx activity were found between individuals with different genotypes, lower blood Se levels were found in Pro/Pro AD patients compared to Pro/Pro control subjects, which was not found in the Pro/Leu groups. Moreover, the association between the erythrocyte Se concentration and GPx activity was affected by the Pro198Leu genotype. Conclusions: Results indicate that this polymorphism had apparently affected Se status in AD patients and that more studies in this field are necessary. Copyright (c) 2012 S. Karger AG, Basel

Structure-property relations in polymers from renewable resources

The present research project focuses its attention on the study of structure-property relations in polymers from renewable sources (bio-based polymers) such as polymers microbially produced, i.e. polyhydrohyalkanoates (PHAs) or chemically synthesized using monomers from renewable sources, i.e. polyammide 11 (PA11). By means of a broad spectrum of experimental techniques, the influence of different modifications on bio-based polymers such as blending with other components, copolymerization with different co-monomers and introduction of branching to yield complex architectures have been investigated. The present work on PHAs focused on the study of the dependence of polymer properties on both the fermentation process conditions (e.g. bacterial strain and carbon substrate used) and the method adopted to recover PHAs from cells. Furthermore, a solvent-free method using an enzyme and chemicals in an aqueous medium, was developed in order to recover PHAs from cells. Such a method allowed to recover PHA granules in their amorphous state, i.e. in native form useful for specific applications (e.g. paper coating). In addition, a commercial PHA was used as polymeric matrix to develop biodegradable and bio-based composites for food packaging applications. Biodegradable, non-toxic, food contact plasticizers and low cost, widely available lignocellulosic fibers (wheat straw fibers) were incorporated in such a polymeric matrix, in order to decrease PHA brittleness and the polymer cost, respectively. As concerns the study of polyamide 11, both the rheological and the solid-state behavior of PA11 star samples with different arm number and length was studied. Introduction of arms in a polymer molecule allows to modulate melt viscosity behavior which is advantageous for industrial applications. Also, several important solid-state properties, in particular mechanical properties, are affected by the presence of branching. Given the importance of using ‘green’ synthetic strategies in polymer chemistry, novel poly(-amino esters), synthesized via enzymatic-catalyzed polymerization, have also been investigated in this work.
