Eine Erklärung, warum manche Wahrheiten notwendigerweise wahr sind, sollte verständlich machen, warum es für diese eine Wahrheitsgarantie gibt. Einen interessanten Ansatz für eine solche Erklärung liefert Kants Definition analytischer Wahrheiten als solche, die bereits in einem Begriff enthalten sind. Die notwendige Wahrheit analytischer Sätze kann hier über das Verhältnis ihrer Bestandteile erklärt werden. Diese Erklärung kann jedoch nur der Anfang einer generellen Erklärung von Notwendigkeit sein, denn einerseits sind nicht nur analytische Urteile notwendig, sondern auch andere, andererseits basiert die Erklärung auf einer umstrittenen Theorie von Begriffen. Die Dissertation untersucht nun, ob und wie die Strategie, Notwendigkeit über das Verhältnis zwischen den Bestandteilen von Repräsentationen zu erklären dennoch ausgeweitet und verteidigt werden kann, um zum Beispiel auch a posteriori Notwendigkeiten und essentialistische Urteile zu erfassen. Indem auf die die Referenz-Relation konstituierenden Fakten Bezug genommen wird, wird gezeigt, dass eine solche Erklärung tatsächlich möglich ist. Notwendige Wahrheit ist demnach eine Eigenschaft von wahrheitsfähigen Repräsentationen, die diese aufgrund des Verhältnisses zwischen den für die Wahrheit der Repräsentation nötigen Fakten und den Fakten, die die Referenz der Bestandteile der Repräsentation bestimmen, hat. Stehen diese in einem bestimmten Verhältnis, wird die Wahrheit der Repräsentation garantiert. Nachdem dieser Ansatz auf eine Reihe von Beispielen angewendet wird, zeigen sich interessante Parallelen zu essentialistischen Theorien von Notwendigkeit und es lässt sich zeigen, dass der Ansatz das Verhältnis zwischen Essenzen und Notwendigkeit richtig darstellt und es sogar erlaubt, ein besseres Verständnis davon zu entwickeln, was Essenzen sind. / An explanation of why some truths are necessarily true needs to make intelligible how it is that a truth is guaranteed to be true. The thesis argues that a promising starting point for an explanation of necessity can be found in Kant’s containment-account of analyticity, for it explains how the truth of a judgment is guaranteed by its structure and the relationship between its constituents. This, however, can merely be a starting point for a general explanation of necessary truth, for it is both too narrow, and presupposes a contentious view of concepts. The thesis thus explores how the general strategy, explaining necessary truth by certain relationships between the constituents of representations, can be expanded to cover further necessary truths, for example a posteriori necessities and essentialist claims. It is argued that the explanation can be generalized by focussing on what it is that constitutes reference between representations and the objects they represent as well as how these representations come together to form truth-evaluable representations. Necessary truth, on this account, is a property of truth-evaluable representations which a representation has in virtue of the appropriate relationship between what is required for its truth, and the way in which the reference of its constituents is determined. The appropriate relationship guarantees the truth of the representation. After applying the theory to a range of examples, interesting parallels to essentialist accounts of necessity emerge and it is argued that the proposed explanation gets the relationship between essence and necessity right and may even be used to elucidate what essences are.

La question de l’effectivité de la sanction pénale fait régulièrement débat. La sanction pénale serait, bien souvent, partiellement effective. Il faut dire que selon une acception classiquement répandue, l’effectivité de la sanction pénale correspondrait au taux d’application de la sanction prononcée et au rapport de conformité entre la sanction prononcée et la sanction exécutée. Tout écart entre ces deux pôles serait la manifestation d’une situation d’ineffectivité. Cette approche de l’effectivité est réductrice, elle ne permet pas d’appréhender cette notion dans sa globalité. Considérant comme effectif « ce qui produit un effet », l’étude de l’effectivité de la sanction pénale ne peut se limiter à une simple vérification de la correspondance entre la sanction prononcée et la sanction exécutée, elle s’étend à l’appréciation des effets produits par la sanction. L’effectivité, qui est un état, ne peut se confondre avec l’exécution qui correspond à l’ensemble du processus permettant d’y parvenir. Au cœur de la recherche de production des effets de la sanction, l’exécution est alors source de l’effectivité recherchée. Selon toute probabilité, la sanction exécutée produira des effets. Pourtant, sauf à vider de son sens la notion d’effectivité, il n’est pas possible de considérer que tous les effets que la sanction est susceptible de produire relèvent de son effectivité. Seuls les effets conformes à la finalité qui lui est assignée intègrent cette notion. Tout en distinguant l’effectivité de l’efficacité, l’effectivité de la sanction s’appréciera à l’aune des effets qui contribuent au maintien de la paix sociale. / The question of the effectiveness of criminal sanction is the cause of great debate. The criminal sanction would be, so often, partially effective. It must be said that according to common thinking, the effectiveness of criminal sanction corresponds to the rate of application of the pronounced sanction and to the relation of conformity between the pronounced sanction and the executed sanction. Any difference between these two poles could be seen as the demonstration of a situation of ineffectiveness. This approach of the effectiveness is simplistic, it does not make it possible to apprehend this notion in its entirety. Considering as effective “what produces an effect”, the study of the effectiveness of criminal sanction cannot be limited to simply checking the correspondence between the pronounced sanction and the executed sanction, it extends to the evaluation of the effects produced by the sanction. The effectiveness, which is a state, cannot nevertheless be confused with the execution which corresponds to the whole of the process making it possible to reach that point. At the core of the search for the production of the sanction’s effects, the execution is then the source of the required effectiveness. In all probability, the executed sanction will produce effects. However, unless we empty the notion of effectiveness of its meaning, it is not possible to consider that all of the effects which the sanction is likely to produce concern its effectiveness. Only the effects in conformity with the finality which is assigned to it integrate this notion. While distinguishing the effectiveness from the efficacy, the effectiveness of the sanction will be assessed in light of the effects which contribute to the maintenance of social peace.

A reposição de glicogênio pós treino foi investigada usando uma mistura de ambos, glicose e glicose-frutose, como repositores, em atletas corredores de longa distância. Dez corredores competitivos (30±4,7 anos) foram avaliados para composição corporal e consumo alimentar antes do exercício de 90 minutos em esteira elétrica a 70% V02máx. Amostras de sangue venoso foram coletadas antes e após o término do exercício, quando eles receberam 1g de carboidrato.kg-1 de uma mistura de ambos, glicose-frutose (CHO1) e glicose (CHO2), e outra com sucralose ou placebo (controle). Amostras de sangue foram retiradas 30, 60, 90 e 120 minutos após o consumo dos suplementos e usadas para determinação de glicose e de ácidos graxos plasmáticos, por reações colorimétricas. Não foram observadas diferenças significativas na composição corporal e na hidratação durante o exercício. Os tratamentos CHO1 e CHO2 produziram elevação na glicemia, em 30 minutos, comparados ao grupo placebo. Entretanto, em 90 min, somente no tratamento CHO1, uma queda na glicemia foi observada (CHO2>CHO1). Os ácidos graxos livres aumentaram comparativamente após o exercício (CHO1=CHO2=placebo) e, diferente do placebo, em 90 minutos, reduziram nos tratamentos CHO1 e CHO2. Ambos os repositores atuaram similarmente nas concentrações de ácidos graxos livres, mas o declínio da glicose plasmática (remoção da glicose) ocorreu primeiramente com o tratamento glicose-frutose do que com o glicose. Assim, a mistura glicose-frutose parece promover uma reposição de glicogênio mais rápida após exercícios de longa duração. / The post training glycogen replacement was investigated using either glucose or glucose-fructose mixture as repositors in long-distance athletes. Ten males (30±4,7yrs) voluntary competitive long distance runners were assessed for body composition and dietary intake prior to a 90 min 70% vo2 max exercise in treadmill. Blood samples were collected before and after the exercise when they received orally 1g of CHO.kg-1 either as maltodextrin-glucose-fructose (CHO1) or maltodextrin - glucose (CHO2) mixtures, having sucralose or placebo (control). Blood samples were drawn 30,60, 90 and 120 minutes after supplement intake and used for plasma glucose and free-fatty acids determinations by colorimetric reactions. There were no significant changes on body composition, mass or hydration, during the treadmill exercise. CHO1 and CHO2 loading increased the 30 min blood glucose both significatively above the placebo. However at 90 min only CHO1 decreased significantily (CHO2>CHO1). The FFA increased comparatively (CHO1=CHO2=placebo) after exercise and differently from placebo CHO1 and CHO2 decreased (similarly) up to 90 min. Both energetic repositors acted similarly on FFA levels but the plasma glucose decreasing (glucose removal) occurred earlier with glucose-fructose loading rather than glucose alone. Thus glucose-fructose mixtures seems to promote faster glycogen repletion after long lasting aerobic exercises.

A infância e a adolescência são consideradas fases que envolvem uma série de transformações entre as quais merecem destaque o crescimento físico e desenvolvimento acelerados que são determinantes de uma maior demanda de energia e nutrientes. É fundamental que os indivíduos adotem alimentação balanceada no tocante à energia e nutrientes para que as mudanças na composição corporal e maturação sexual, entre outras demandas, sejam asseguradas. Entre os objetivos principais da pesquisa destacam-se a análise do estado nutricional, consumo de energia e nutrientes e a participação dos macronutrientes na dieta de amostra de 1325 escolares, matriculados em vinte unidades de ensino de dez municípios brasileiros. Os dados referentes ao consumo de alimentos foram obtidos por meio da adoção do método Recordatório 24- horas. Para a elaboração das análises nutricionais foi utilizado o software Virtual Nutri (Philippi et al., 1996). Os resultados revelam ingestão média de energia (1503,4 kcal) que pode ser considerada menor que à recomendação definida para os alunos do grupo etário da amostra. Quando se analisou a situação dos escolares, de acordo com a participação dos macronutrientes no Valor Energético Total da Dieta - VET, observouse que, de forma geral, a maioria (55%) adota dieta inadequada, sendo que as situações mais desfavoráveis atingem os estudantes dos municípios das Regiões Nordeste (Parnaíba e Brasileira) e Norte (Abaetetuba e Tailândia). Situação inversa foi identificada no tocante às dietas dos escolares de Joinville-SC (71,3% do grupo adotavam dietas adequadas). A análise do estado nutricional revelou que é nula a prevalência de baixo peso entre os alunos da totalidade das vinte escolas integrantes da pesquisa. De foram geral a maioria (cerca de 92,6%) foi classificada como eutrófica e proporção de escolares próxima à esperada identificada com sobrepeso. No entanto, nos municípios da Região Sul, os resultados distinguem-se pela superioridade da prevalência de sobrepeso em relação aos demais: proporções de escolares (14,7%) de Joinville e 16,3%, em Ponte Serrada foram diagnosticados com excesso de peso. Note-se que os referidos percentuais são praticamente três vezes maiores quando comparados à proporção observada (5%) em populações considerado de referência. Quanto ao consumo de minerais, merece atenção a reduzida ingestão de cálcio (a maioria dos escolares não ingeriu 50% do valor preconizado). O consumo (médio) de praticamente a totalidade das vitaminas selecionadas pode ser considerado relativamente mais favorável, exceto quando se verifica, entre os alunos a baixa ingestão de folacina e ácido pantotênico. A reduzida presença de fibras da dieta da totalidade dos escolares causa preocupação, especialmente quando atenção é dirigida aos valores preconizados (25 a 38g/dia): o maior consumo foi observado entre os alunos de Parnaiba (14,3 g), enquanto em Joinville, a ingestão alcançou 7,9 g (menor quantidade média identificada). Não sobram dúvidas que o grupo formado por crianças e adolescentes, especialmente aqueles matriculados nas unidades da rede pública de ensino, merece a atenção dos órgãos de saúde e educação, principalmente no tocante ao monitoramento do consumo de alimentos. / Childhood and adolescence are considered periods that involve a series of changes in which some of them are worth enlightening: the physical growth and development that requires a higher intake of energy and nutrients. It is important that these subjects have a balanced food intake concerning energy and nutrients to reassure that the changes such as in body composition and sexual maturation are guaranteed. One of the most important goals of this work is the assessesment of the nutritional status, the energy and nutrients intake, and the macronutrients present in diets of a sample of 1325 students, enrolled in 20 public schools in 10 Brazilian states. The data on the students food intake were obtained using the 24-hour Recall Method. To the nutritional analyses the software Virtual Nutri was used. It was identified among the main findings an average of energy intake (1503.4 kcal) which was considered below the recommended allowance for the group. When the distribution of the students according to the participation of the macronutrients in the total energy value of the diet was analyzed, it was observed that most of them (55%) has inadequate diets, being the worst situations among students of the Northeast Region (Parnaíba and Brasileira) and the North Region (Abaetetuba and Tailândia). The opposite was found among the students from Joinville-SC (71,3% of the group had diets classified as adequate). The analyses of the nutritional status found no prevalence of low weight among the students in the study. Most of them (around 92.6%) were classified as eutrophic and an expected rate (5%) was identified as overweight. Nonetheless among the students from Joinville (14.7%) and Ponte Serrada (16.3%) the results related to overweightness (percentages practically 3 times higher) distinguished by the superiority over the others. Regarding the consumption of minerals, it is surprisingly the low intake of calcium: most of them hadn’t had 50% of the recommended allowance. In relation to the average intake of vitamins the situation can be classified as more regular, except when the reduced intake of folacin and pantotenic acid is considered. The average content of fibers in the diets of all the students is cause of worries especially when the recommended daily allowance (25 to 38g): the highest intake was observed in students from Paraiba (14.3g) and the lowest was identified in students from Joinville. There are no doubts that the group of children and adolescents, especially the ones who attend public schools deserve close attention from the health and educational institutions concerning to food comsuption.

Cette thèse est une investigation de la structure syntaxique et de l'interprétation modale des phrases impliquant le modal dénominal de nécessité behar ‘devoir, falloir, avoir besoin’ et un complément infinitif. La thèse analyse le statut syntaxique des compléments non finis du verbe modal denominal behar en examinant leur interaction avec des phénomènes syntaxiques sensibles à des conditions structurelles et de localité diverses, et conclut que les compléments d’infinitif de behar peuvent correspondre à différentes structures sous-jacentes. Le type d'infinitif le plus complexe du point de vue structurel est un infinitif non-restructurant qui projette une architecture de phrase complète (c.-à-d. une CP), et le plus petit est un infinitif réduit de restructuration qui projette une structure de phrase de niveau vP. Il y a des preuves pour l'existence des types intermédiaires projetant jusqu'au domaine flexionnel (IP / TP). D'autre part, la thèse examine les propriétés thématiques et de portée des sujets dans chacun des différents types structurels et l'interprétation modale à laquelle elles donnent cours. Sur la base de cette analyse, la thèse soutient que l'interprétation modale n'est déterminée par aucun facteur en particulier (la présence de la restructuration, le statut référentiel du sujet et sa portée relative vis-à-vis du prédicat modal, parmi d'autres fréquemment mentionnés), mais dépend de l'effet cumulatif de plusieurs facteurs travaillant ensemble. La thèse montre également la nécessité d'adopter une vision plus fine de la modalité radicale (root modality), qui permet une association plus simple entre structures syntaxiques et significations modales. / This dissertation is an investigation of the syntactic structure and modal interpretation of clauses involving the denominal necessity predicate behar ‘need’ and an infinitival complement. On the one hand, it analyses the syntactic status of non-finite complements of denominal behar by examining their interaction with syntactic phenomena sensitive to different structural and locality conditions, and concludes that the infinitival complements of behar can correspond to different underlying structures. The largest type of infinitive is a non-restructuring infinitive that projects a full clausal architecture (i.e. a CP), and the smallest one is a reduced restructuring infinitive that projects up to vP. There is evidence for intermediate types projecting up to the inflectional domain (IP/TP). On the other hand, the dissertation examines the thematic and scope properties of the subjects in each of the different structural types and the modal interpretation that they can give rise to. On the basis of this analysis it is argued that modal interpretation is not constrained by any single factor (the presence of restructuring, the referential status of the subject and its relative scope vis-à-vis the modal predicate, among other frequently mentioned ones), but depends on the cumulative effect of several factors working together. The dissertation also shows the necessity of adopting a more fine-grained view of root modality, one that allows a simpler mapping of syntactic structures into modal meanings.

For a better comprehension of the subject, we approached the concept of social security and its historical evaluation. After this preliminary examination, we made a few considerations about the social security under the Brazilian law. When we dealt with the pension for death benefits within the Social Security s General Regime of the national law, we analyzed all the criteria that integrate its hypothesis (material, space and time criteria) and its consequent ruling (personal and quantitative criteria). As a critical argument related to the approached matter, we tried to demonstrate situations in which the survivors benefits in Brazil should not be granted because the social necessity requisite is not present. In the final part of this dissertation, as an attempt to reach conclusions and suggestions for the improvement of the pension for death benefits under the Brazilian Social Security s General Regime, we discoursed upon the pension for death benefits in Portugal, Spain, Italy, Chile and the United States of America / O escopo desta dissertação é estudar o benefício previdenciário pensão por morte no Regime Geral da Previdência Social brasileiro em cotejo com o ordenamento alienígena. Para melhor entendimento do tema, abordamos o conceito de seguridade social e sua evolução histórica. Após este exame preliminar, tecemos algumas considerações sobre a previdência social no direito brasileiro. Ao tratarmos do benefício previdenciário pensão por morte, no Regime Geral da Previdência Social do direito pátrio, analisamos cada um dos critérios que integram a sua hipótese (critérios material, espacial e temporal) e seu conseqüente normativo (critério pessoal e quantitativo). Como argumento crítico ao tema abordado procuramos demonstrar situações em que o benefício pensão por morte no Brasil não deveria ser concedido, pois não estaria presente o requisito da necessidade social. Na parte final desta dissertação, buscando conclusões e sugestões para o aprimoramento da pensão por morte, no Regime Geral da Previdência Social brasileiro, discorremos sobre a pensão por morte de Portugal, Espanha, Itália, Chile e Estados Unidos

La thèse a pour objet de démontrer l'émergence du principe de nécessité dans l'action normative au niveau de l'Union européenne. Après une partie concernant la notion générale de nécessité et le rôle des principes dans l'ordre juridique de l'Union, le cadre juridique des traités est examiné à l'aune du principe de nécessité. L'analyse est faite sur base des dispositions pertinentes des traités ainsi que des actes législatifs adoptés par le législateur de l'Union et des critères qui ressortent de la jurisprudence de la Cour de justice en matière pénale. Une distinction est opéré entre (1) les dispositions concernant la coopération judiciaire en matière pénale et la procédure pénale (article 82 TFUE), (2) le droit pénal autonome (article 83, paragraphe 1, TFUE), et (3) le droit pénal accessoire (article 83, paragraphe 2, TFUE) de l'Union. Des documents concernant les prises de position de certaines institutions de l'Union sont également examinés. À l'issue de l'analyse, l'on conclut à l'émergence d'un principe de nécessité, à la lumière aussi de l'évolution de la pratique législative. / This thesis has as its purpose to demonstrate the appearance of the principle of necessity in the legislative action of the European Union in the field of criminal law. After a first part which concerns the general notion of necessity and the role of principles in the Union's legal order, the legal context of the EU Treaties is examined in the light of the principle of necessity. The analysis is made on the basis of the relevant provisions of the Treaties as well as on the basis of the legislative acts adopted by the Union's legislature and takes into account the criteria coming from the case law of the Court of Justice in criminal law related matters. A distinction is made between (i) the provisions concerning judicial cooperation in criminal matters and criminal proceedings (Article 82 TFEU), (ii) autonomous criminal law (Article 83(1) TFEU), and (iii) ancillary criminal law (Article 83(2) TFEU) of the European Union. A number of documents concerning the positions taken by some Institutions of the European Union are also analysed. In the final analysis, it is concluded that the principle of necessity appears in the Union's criminal law, also in the light of the evolution of the legislative work.

L.) under organic management in system of seeding with prepare soil and no till cropping system. This work was conducted in the experimental area of SIPA (Integrated system of agro ecological production), at the county of Serop?dica RJ, with the aim of valuate the growth , the water needs, and the efficiency of the use of the water by the bell pepper culture (Capsicum annuum. L ), at the conventional (PC) and the direct systems of soiling. The conventional system consisted of soil prepare with rotational hoe tied to a micro tractor, and the direct soiling, being done after the occupation of the area with a combination of Sorghum bicolor and Crotal?ria acroleura, that was grazed at the transplantation of the bell pepper s seedlings without previous soil preparation. The same fertilization and cultural practices permitted by the agro ecological handling, was used in both systems. The two systems tested, received sprinkler irrigation, and the determination of the water s blade, was made by monitoring with TDR (Time Domain Reflectometry), calibrated for the soil conditions of the experimental area. The splits were also monitorated by a tensiometer at a 50 cm. deep. Collects were made at intervals of 14 days, with the aim of foliar area evaluation, biomass accumulation by the parts of the plant, along the entire cycle, being also evaluated the crop production at the two systems of soiling. By the adjustment of the IAF (Foliar Area Indices ) and the biomass accumulated by the plant at the two systems of planting in function of accumulated day-degree (GDA), was verified that 1533 GDA was necessary to complete the productive cycle, reaching the top of accumulated biomass at 1059 and 1148 GDA, at PC and PD respectivement. There were no differences between the systems of planting, in respect of the growth rate and the productivity, however the PD system gave less competition between spontaneous vegetation and the bell pepper crop, reducing in 60% the necessity of hand labor at the firsts weddings. The PD system raise the efficiency of the use of water (EUA) by the crop reducing in 47,5 mm. the blade applied during its cycle, in relation of PC. The irrigation handling using TDR, provide an meaning EUA of 4,4 Kg.m-3, above the means of 1,5 to 3,0Kg.m-3, recommended by Doorenbos & Kassam (1994). The culture coefficients (Kc) recommended for the bell pepper crop, were evaluated together with the calculated coefficients using some methodologies proposed in this work, and was noted that the estimated Kc s values of the production cycles (ETc cycle) and by the Kc curve (graphic ETc) estimated during the culture cycle, were more appropriated for the calculation of the evapotranspiration of the crop. The estimation of reference evapotranspiration (ETo), by the pan class A method, made possible means close to those estimated by the Penman-Monteith model witch is recommended by FAO as standard. Therefore, the pan class A method, can be utilized in the estimated ETo, at same conditions of the experiment when there are no data of climate for the Penman-Monteith model use. Associated tensiometry and TDR for irrigation management, showed to be an essential practice when looking for raising the efficiency of the use of water. / Este trabalho foi realizado na ?rea experimental do SIPA (Sistema Integrado de produ??o Agroecol?gica), localizada no munic?pio de Serop?dica-RJ, com o objetivo de avaliar o crescimento, as necessidades h?dricas e a efici?ncia no uso da ?gua pela cultura do piment?o (Capsicum annuum. L), nos sistemas de plantio convencional (PC) e direto (PD). O sistema convencional consistiu de preparo de solo com enxada rotativa acoplada a micro-trator e o plantio direto, na ocupa??o da ?rea com pr?-cultivo, utilizando o cons?rcio Sorghum bicolor e Crotal?ria acroleura, os quais foram ro?ados por ocasi?o do transplante das mudas de piment?o, sem o preparo pr?vio do solo. Em ambos os tratamentos a cultura recebeu a mesma aduba??o de cova e tratos culturais permitidos pelo manejo agroecol?gico. Nos dois sistemas de plantio a cultura foi irrigada por aspers?o, e a determina??o das l?minas aplicadas, foi realizada atrav?s do monitoramento com TDR (Reflectometria no dom?nio do tempo), calibrado para as condi??es de solo da ?rea experimental. As parcelas foram monitoradas tamb?m por tensi?metro no perfil de 50cm de profundidade. Foram realizadas coletas em intervalos de 14 dias com a finalidade de avaliar a ?rea foliar e acumulo de biomassa pelas partes da planta, durante todo o seu ciclo, sendo avaliado tamb?m a produ??o pela cultura nos dois sistemas de plantio. Por meio do ajuste do IAF e da biomassa acumulada pela planta nos dois sistemas de plantio em fun??o de graus-dia acumulado (GDA), constatou-se que s?o necess?rios 1533 GDA para que a planta complete o seu ciclo produtivo, atingindo o m?ximo de biomassa acumulada aos 1059 e 1148 GDA, no PC e PD, respectivamente. Os sistemas de plantio n?o diferiram significativamente entre si com rela??o ?s taxas de crescimento e produtividade, entretanto o plantio direto proporcionou menor competi??o da vegeta??o espont?nea com a cultura, reduzindo em 60 % a necessidade de m?o-de-obra nas primeiras capinas. O PD aumentou a efici?ncia no uso da ?gua (EUA), pela cultura, reduzindo em 47,5mm a l?mina aplicada durante o seu ciclo, em rela??o ao PC. O manejo da irriga??o utilizando o TDR, proporcionou a EUA m?dia de 4,4kg.m-3, acima dos valores 1,5 a 3,0kg.m-3 propostos por Doorenbos e Kassam (1994). Os Coeficientes de cultivo (Kc) recomendados para a cultura, foram avaliados juntamente com os calculados por v?rias metodologias propostas neste trabalho, verificando-se que os valores de Kc estimados em fun??o dos ciclos de produ??o (ETc ciclo) e pela curva de Kc (ETc gr?fico) estimados durante o ciclo da cultura, se mostraram mais adequados ao c?lculo da evapotranspira??o da cultura. A estimativa da evapotranspira??o refer?ncia (ETo), pelo m?todo do tanque classe A , possibilitou valores pr?ximos aos estimados pelo modelo de Penman-Monteith recomendado pela FAO como padr?o. Portanto o m?todo do tanque classe A poder? ser utilizado na estimativa da ETo, em condi??es semelhantes a do experimento, quando n?o houver disponibilidade de dados clim?ticos para o uso do modelo de Penman- Monteith. O uso da tensiometria associado ao TDR no manejo de irriga??o revelou ser uma pr?tica indispens?vel, quando se almeja aumentar a efici?ncia no uso da ?gua.

<p>Obemannade flygplan med attackförmåga (UCAV) används i allt större utsträckning i konflikter idag. En av de främsta fördelarna med dessa är att det inte finns någon risk att mista en pilot, då dessa är fjärstyrda. I attacker utförda av amerikanska UCAV:er i framför allt Afghanistan och Pakistan, har collateral damage inträffat vid ett flertal tillfällen. Det innebär att civila oavsiktligt fallit offer för attacker. Enligt krigets lagar kan sådana händelser rättfärdigas av att militär nödvändighet föreligger, men det är tveksamt om det går att hävda det när man inte riskerar egna förluster. Detta innebär i så fall att collateral damage alltid är krigsbrott när det orsakats av UCAV. Då är det viktigt att det går att utkräva ansvar ur obemannade system och det finns farhågor att ansvarsförhållandena blir otydligare när det inte sitter en pilot i flygplanet som ”trycker på knappen”. Men så länge den obemannade farkosten fjärrstyrs och besluten tas av en människa går det inte att se några skillnader i möjligheten till ansvarsutkrävande från bemannade system.</p> / <p>The use of Unmanned combat aerial vehicles (UCAV) has seen an increasing use in modern conflicts. One of the main advantages of these is the fact that there is no risk of losing a pilot, as the aircraft are remote-controlled. The attacks carried out by U.S. UCAVs in Afghanistan and Pakistan have resultet in a number of incients with collateral damage. According to the laws of war, only military necessity can justify such incidents and it is highly doubtful if you can claim such necessity when you do not risk any loss of life yourself. This would mean that collateral damage caused by UCAVs automatically becomes a war crime. This raises the issue of accountability and wether it is possible to extract such from unmanned systems. There are fears that this would be difficult when no pilot is present in the aircraft to ”pull the trigger”. However, as long as operators remotely control the unmanned aircraft and the decision to release weapons in anger are made by humans, there are no differences to be found in terms of accountability between manned and unmanned systems.</p>
