Pasaulio ekonomikos augimas, spartėjantis globalizacijos procesas, technologijų pažanga didina atstumus tarp žaliavų gavimo, gamybos ir pagamintų prekių naudojimo taškų. Gausėjant prekybinių ryšių bei plečiantis jų geografijai, didėja reikalavimai transporto ir logistikos paslaugas teikiančiam sektoriui. Regionų ekonominis augimas priklauso nuo to, kaip transporto sistema geba patenkinti žaliavų tiekėjų, gamintojų, prekybininkų ir vartotojų logistikos poreikius laiko, greičio, saugumo, sąnaudų prasmėmis. Transporto srautai ilgainiui prisitaiko prie kintamų regiono logistikos poreikių, tačiau dėl transporto sistemos inertiškumo tam sugaištama laiko. Lietuvoje reikšminga dalis bendrojo nacionalinio produkto sukuriama transporto ir logistikos sektoriuje, kadangi šalis yra stambių tranzitinių krovinių srautų kryžkelėje. Lietuvai tapus Europos Sąjungos nare, atsiveria tarptautinės prekybos augimo galimybes, Lietuva tampa Europos Sąjungos buferine zona prekybai su Rytų bloko šalimis, taigi teisinga Lietuvos transporto sistemos plėtros strategija gali suteikti Lietuvai didžiulį ekonominį potencialą, bendrojo vidaus produkto ir darbo vietų skaičiaus augimo perspektyvas. Transporto srautams užtikrinti būtina transporto infrastruktūra, kurios plėtrai yra labai svarbu nustatyti potencialius krovinių srautus. Transporto infrastruktūra labai imli kapitalui, todėl jos plėtros kryptys turi tiksliai atitikti logistikos poreikius, priešingu atveju milžiniškos investicijos nepateisinamos...

Full textAbstract:
A partir da década de 1980, passou-se a adotar um regime de transporte internacional mais condizente com a redução de custos operacionais e com a facilidade de contratação. Esse misto de operação de transporte com aspectos contratuais específicos fora denominado transporte multimodal, sendo utilizado também para o fortalecimento da integração regional em transportes no âmbito de blocos econômicos regionais. A preocupação inicial de organizações internacionais tais como a CNUCED, CNUDCI, OMI, OACI e de órgão privados internacionais tais como a CCI, ATAI, CMI foi fundamental no despertar da sociedade internacional para o papel essencial dos transportes no comércio internacional, sendo protagonista de várias modificações no cenário global. No plano regional mercosulista, essa preocupação com os temas relacionados aos transportes também foi abordado por meio do estabelecimento de regras relacionadas ao transporte multimodal de cargas, seguindo o modelo convencional estabelecido na Associação Latino-Americana de Integração, com a implementação do Acordo parcial para a facilitação do transporte multimodal nos Estados-partes do Mercosul de 1994. O objetivo do presente estudo é realizar uma avaliação dos desafios e dos limites jurídicos estabelecidos atualmente para a consecução da eficiência da multimodalidade no Mercosul, tal como estabelecido desde o Acordo de 1994. Avaliaram-se as regras convencionais atuais relevantes para o estudo da regulamentação do transporte multimodal por meio da política de transporte; do regime jurídico do Acordo de Ministros de 1996, das regras CCI-CNUCED; dos regimes nacionais do transporte multimodal na Argentina, Brasil, Paraguai e Uruguai e o impacto das novas Regras de Roterdã da CNUDCI de 2009. Em seguida, passou-se à interpretação da viabilidade da aplicação da multimodalidade na conjuntura institucional atual da integração mercosulista. A relevância do presente estudo se dá por ser um instrumento de avaliação da opção pela implementação da multimodalidade no Mercosul, baseando-se em estudo de normas jurídicas sub-regionais. Como conclusão, é perceptível a falta de harmonização de regras de transporte multimodal no Mercosul, de tal maneira que a legislação mercosulista não está baseada em um regime normativo propício para a eliminação ou redução de custos da integração regional por meio da multimodalidade.Since eighty years, economic agents have adopted an international transport regime more appropriated for operational costs reductions and facilities on contracting. This mixture of transport operation and specifics contractual aspects were named multimodal transport and were also used for strengthen regional economic integration on transports in economics regions. Some main preoccupations of international organizations e. g. UNCTAD, UNCITRAL, IMO, ICAO and international private entities e. g. ICC, IATA, IMC were fundamental to international society in playing the part of international commercial transport. In Southern Common Market regional plan this concern related to transport also was broached by establishing rules to multimodal transport as the model of Latin American Association of Integration on the Partial agreement to the facilitation of multimodal transport in Members States of Southern Common Market of 1994. The objective of this studying is to analyze challenges and legal limits established nowadays to the efficiency of multimodal transport on Southern Common Market since 1994 Agreement. It was evaluated some treaties related to multimodal transport regulation, legal regime of Ministers Agreement of 1996, ICC-UNCTAD Rules, national regimes of multimodal transport in Argentina, Brazil, Paraguay and Uruguay and the impact of new UNCITRAL Rotterdam Rules of 2009. Besides that it was evaluated the feasibility to multimodal transport in Southern Common Market integration. The main importance of this studying is to be an instrument of evaluation of the application of multimodal transport in Southern Common Market through regional legal rules. As conclusion it is perceptible the absence of harmonization on multimodal transport that prove an existence of a non propitious legal regime to eliminate or reduce regional integration costs through multimodal operations.

Smith, Neil C. E. "Carrier-mediated transport of norepinephrine transporter substrates." Thesis, University of Surrey, 2000. http://epubs.surrey.ac.uk/843076/.
Full textAbstract:
An overview of the noradrenergic system, including the identification of norepinephrine (NE) in animal tissue, its synthesis and metabolism, adrenoceptor classification, peripheral and central actions, uptake and storage, and mechanisms of NE release are presented. After characterizing the kinetic, ion dependence and inhibitor sensitivity of the norepinephrine transporter (NET) expressed in a recombinant cell line (LLC-NET cells), the influence of catecholamine (CA) metabolizing enzymes on studies of transport was assessed. Inhibitors of catechol-O-methyltransferase (COMT) potentiated the apparent uptake and retention of [3H]NE and [3H]DA. COMT inhibition had a greater influence on [3H]DA than [3H]NE uptake and retention, which corresponds to the higher spontaneous loss of radiolabel from cells exposed to [3H]DA than [3H]NE ([3H]methoxytyramine, is more lipophilic than [3H]normetanephrine). The monoamine oxidase inhibitor, pargyline, had no augmentary action on [3H]CA uptake, but actually inhibited substrate influx by blocking the NET. [3H]substrate specific differences were demonstrated for [3H]NE, [3H]DA and [3H]MPP+. For a given length of exposure to low Na+ or tyramine, [3H]NE release was the lowest, but most sensitive to NET inhibitors. Disparities in the kinetics of each [3H]substrate for the inwardly facing NET may account for this. Inhibitors of the NET were found to stimulate the efflux of [3H]substrates from preloaded cells incubated in a physiological HEPES buffer. Efflux was NET-dependent and differed greatly for each [3H]substrate. Inhibitor-induced release was greatest for [3H]MPP+ and least for [3H]NE. Finally, a functional model of carrier-mediated NE release in myocardial ischemia, was developed in this study. Release of [3H]MPP+ was stimulated by Na+-H+ exchanger (NHE) activation and modulated by inhibitors of the NET, NHE, Na+,K+-ATPase, and via a receptor-operated pathway. Excessive NE release contributes to severe myocardial arrhythmias, therefore an improved understanding of the carrier-mediated NE release process will ultimately enhance our ability to intervene and prevent the deleterious effects of excessive NE release.

Cette thèse essaye de dévoiler l'empreinte laissée par les processus de régionalisation sur le système de transport. Ont été étudiées d'abord les transformations subies par le cadre institutionnel et juridique, notamment la redistribution des pouvoirs et des financements entre les différents échelons de l'organisation territoriale de l'Etat. En deuxième lieu, il a été question des politiques de transport adoptées par les institutions régionales. Avec ces analyses, on a confirmé l'influence réciproque de la régionalisation et du système de transport. L'ensemble de l'intervention publique sur les transports s'en trouve modifiée, ne serait-ce que par la multiplication des acteurs, car les changements opérés dans l'organisation institutionnelle provoquent des transformations dans les processus de décision et dans les modes de gestion, ce qui constitue le principal objectif de la régionalisation. Parallèlement, la reterritorialisation des réseaux de transport agit comme un outil privilégié de la régionalisation elle-même

Darbo tikslas – atlikti Lietuvos autotransporto sektoriaus rodiklių analizę darnaus aplinkos būklės, ekonominio ir socialinio vystymosi aspektais 2000–2011 m.
Vykdant išsikeltus darbo uždavinius buvo renkami, grupuojami, ir analizuojami statistiniai duomenys susiję su transporto sektoriaus darniu vystymusi ir apimantys šio sektoriaus aplinkosauginius, ekonominius bei socialinius aspektus.
Analizuojamas laikotarpis apima 2000 – 2010 metus. Per šį laikotarpį Lietuvos transporto sektorius labai vystėsi.. Kelių transporto priemonių skaičius 2000 – 2006 padidėjo 40 %. Vėliau šis augimas nebuvo toks ryškus. Kuro sunaudojimas transporto sektoriuje per analizuojamą laikotarpį išaugo 50 proc. Kuro suvartojimas transporto sektoriuje sumažėjo dabartinės ekonominės krizės metu. Vis didesnę dalį krovinių ir keleivių apyvartos užima kelių transportas. Keleivių vežimas viešojo naudojimo autobusais iki 2008 metų padidėjo 22 %.
Transporto sektoriaus sukuriama BVP dalis 2000 – 2008 metų periodu augo 25 %. Darbuotojų skaičius transporto sektoriuje per 2000 – 2010 metų laikotarpį sumažėjo 16 %, tai rodo, kad net ir maža dalis dirbančiųjų transporto sektoriuje sukuria gan didelę dalį bendrojo Lietuvoje sukuriamo BVP. Bendras kelių tinklas išaugo 10 %. Lietuvoje gyventojų mirtingumas dėl transporto įvykių sumažėjo 54 %. Krovinių vežimas visomis transporto rūšimis iki 2008 metų augo, vėliau pastebimas sumažėjimas dėl finansų krizės. Ir tik nuo 2009 metų pastebimas pervežamų krovinių skaičiaus...

Fuel consumption in the transport sector dropped in the current economic crisis. An increasing share of freight and passenger turnover of road transport occupies. Passengers carried by public buses by the year 2008 increased by 22%. Transport sector in the GDP of 2000 - 2008 season increased by 25%. Number of employees in the transport sector during 2000 - 2010 the period decreased by 16%, suggesting that even a small proportion of workers in the transport sector creates a relatively large part of total GDP generated in Lithuania. The total road network grew by 10%. Lithuania mortality rate of traffic accidents decreased by 54%.

Le but de cette thèse est de décrire la problématique de la concurrence entre le transport combiné et le transport routier, par une analyse quantitative des facteurs influant le choix du transport combiné intérieur. Cette analyse s'appuie sur des outils économétriques du choix du mode de transport qui reposent sur la théorie de la maximisation de l'utilité du consommateur. Une double démarche de la modélisation a été conduite afin de trouver les facteurs sensibles a l'égard du transport combiné; d'une part, la modélisation agrégée du partage modal à l'aide des données recensées sur un échantillon de 44 axes principaux du transport combiné intérieur, et d'autre part, la modélisation désagrégée a l'aide des données tirées de l'enquête auprès des chargeurs de l'INRETS. Les résultats obtenus au cours de ce travail sont plutôt encourageants. Notre étude confirme que les facteurs tels que le prix et la distance ont une forte influence sur le choix du transport combiné. En plus, d'autres facteurs tels que les plages horaires de départ des trains, les différentes catégories de chargeurs et la valeur au kilo de l'envoi se révèlent également sensibles vis-à-vis du choix du transport combiné. La méthode utilisée permet de prévoir l'influence de la concurrence sur le marché de transport de fret et peut s'avérer aussi un outil d'analyse dans le but d'éclairer la politique du développement du transport combiné

Face à la concurrence du transport routier de marchandises et aux changements structurels du système productif, le fret Sncf subit depuis vingt ans une profonde mutation. Ce contexte de forte évolution amène à quantifier les effets de la croissance et des prix des transports sur les trafics en distinguant les fonctions de demande des transports de court et de long termes. L'analyse statistique faite sur des périodes glissantes permet de mieux cerner la stabilité ou non-stabilité des relations et de mieux cadrer les outils utiles à la prévision. La diversité de la demande justifie la segmentation des trafics suivant la nature des - produits transportes. La spécificité des marchés amène à affiner les bases de données sur les prix des transports routiers et ferroviaires. Il apparait également nécessaire de faire intervenir les variables d'échange (importations et exportations) et de différencier les variables de croissance suivant les branches de l'économie. Tout cela permet de mieux appréhender des caractéristiques de prix de transport et de qualité de service au niveau de la concurrence entre le rail et la route. En réponse à l'évolution de la demande, la Sncf a mis en place une prestation multimodale : le transport combiné. Une modélisation des parts de marche tenant compte de la diversité des relations et du contexte de forte évolution est développée avec des techniques de panel. Elle quantifie les effets de la qualité de service et des prix du transport combine sur la répartition des parts de marché des trafics du combine et du mode routier en séparant les axes de courte et de longues distances. Ces analyses quantitatives apportent un complément d'aide à la décision dans les choix stratégiques de développement du fret SncfFaced with the competition of road transport of goods and with the structural changes of production system, the SNCF freight has undergone massive changes in the last twenty years. In this context of deep evolution, it is essential to measure the effects of economic growth and transport prices on traffic, by separating the short and the long-term in the demand functions. The statistical analysis carried out on different periods of time enables us to determine more precisely the stability or non-stability of the relations and the tools useful for forecasting. The diversity of the demand justifies to segment the traffics according to the nature of the transported goods. The specificity of the markets leads to refine the databases on road and rail transport prices. It also seems necessary to introduce the variables of foreign exchange (imports and exports) and to differentiate the variables of growth according to industrial fields. All this allows to define more accurately the characteristics of transport prices and service quality at the level of the competition between rail and road. In response to the changing demand, the SNCF has set up a multimodal service : the combined transport. A modelling of market shares is developed with the cross-sectional data technique, according to the diversity of the relations and the context of drastic evolution. It measures the effects of service quality and combined transport prices on combined and road traffics market shares, while distinguishing between short and long distance axis. These quantitative analyses bring an additional help to make the strategic choices in the development of the SNCF freight

Introdução: O transporte médico de crianças gravemente enfermas envolve particularidades que aumentam o risco de complicações, que podem contribuir para o aumento no tempo de internação e mortalidade. Objetivos: Avaliar a frequência e os tipos de complicações observadas durante o transporte pré- hospitalar e inter-hospitalar de crianças gravemente enfermas, assim como o impacto dessas complicações na mortalidade, no tempo de internação hospitalar e nos custos hospitalares. Pacientes e Métodos: Estudo realizado em duas etapas: a primeira foi um estudo transversal, no qual, por meio de entrevista padronizada com o médico que admitiu as crianças gravemente enfermas que necessitaram de transporte pré-hospitalar ou inter-hospitalar, foram identificadas e caracterizadas possíveis complicações ocorridas durante esse transporte. Estes dados foram auditados por três médicos independentes que definiram a presença ou ausência de complicações durante o transporte. A segunda etapa constituiu-se de uma coorte prospectiva, na qual os pacientes, divididos em dois grupos distintos (com e sem complicações durante o transporte), foram seguidos, prospectivamente, por 60 dias, observando-se a ocorrência de morte ou alta hospitalar. Resultados: Foram incluídas 143 crianças no estudo. Pelo menos uma complicação durante o transporte foi observada em 74 pacientes (52%). As complicações mais frequentes foram relacionadas com as vias aéreas (69%), seguidas por distúrbios metabólicos (47%), alterações cardiovasculares (40%) e falhas relacionadas aos dispositivos e à monitorização (37%). Na análise univariada, os seguintes preditores para ocorrência de complicações durante o transporte foram observados: peso <10Kg (risco relativo - RR: 1,52; intervalo de confiança (IC 95%: 1,11-2,09); distância >100Km (RR: 1,67; IC 95%: 1,16-2,40); presença de doença respiratória (RR: 1,46; IC 95%: 1,06-1,95) e comorbidades (RR: 1,68; IC 95%: 1,23-2,30). Já na análise multivariada, não foram observados preditores independentes para ocorrência de complicações. A ocorrência de complicações durante o transporte foi associada com maior taxa de mortalidade hospitalar (hazard ratio - HR: 5,668; IC 95%: 1,26-26,65; p=0,0130) e menor taxa de alta hospitalar (HR: 0,48; IC 95%: 0,31-0,74; p=0,0007). Após a aplicação da regressão de Cox para ajuste de potenciais fatores de confusão, a presença de complicação durante o transporte permaneceu associada com o índice de mortalidade hospitalar (HR: 6,74; IC 95%: 1,40-32,34; p=0,017), contudo deixou de ser associada com o tempo para a alta hospitalar (HR: 0,76; IC 95%: 0,49- 1,16; p=0,213). Conclusões: As complicações foram frequentes durante o transporte pediátrico. A presença de doenças respiratórias, peso <10Kg, presença de comorbidades e a distância >100 Km foram preditores de risco para a ocorrência dessas complicações. As complicações ocorridas durante o transporte foram associadas com o aumento nas taxas de mortalidade hospitalar.Introduction: The medical transport of critically ill children involves characteristics that increase the risk of complications, which can contribute to an increase in length of stay and mortality. Objectives: To evaluate the frequency and type of complications observed during the pre-hospital and inter-hospital transport of critically ill children, as well as the impact of these complications on mortality, length of hospital stay and hospital costs. Patients and Methods: A study carried out in two stages: the first was a cross-sectional study where through a standardized interview with the doctor who admitted the critically ill children requiring pre-hospital or inter-hospital transport identified and characterized possible complications during this transport. These data were audited by three independent doctors who defined the presence or absence of complications during transport. The second stage consists of a prospective cohort study, where patients divided into two groups (with and without complications during transportation) were followed prospectively for 60 days observing the occurrence of death or hospital discharge. Results: We included 143 children in the study. At least one complication during transportation was observed in 74 patients (52%). The most frequent complications have been associated with airway (69%), followed by metabolic disorders (47%), cardiovascular disorders (40%) and failure in the device and monitoring (37%). In the uni-variate analysis, the following predictors for the occurrence of complications during transport were observed: weight <10 kg (relative risk - RR: 1.52; 95% confidence interval - CI: 1.11-2.09); distance greater than 100 km (RR: 1.67; 95% CI: 1.16-2.40); presence of respiratory disease (RR: 1.46; 95% CI: 1.06-1.95) and associated comorbidity (RR: 1.68; 95% CI: 1.23- 2.30). In the multivariate analysis, no independent predictors were observed for the occurrence of complications. The occurrence of complications during transport was associated with higher hospital mortality (hazard ratio - HR: 5.668; 95% CI: 1.26-26.65; p=0.0130) and a lower hospital discharge rate (HR: 0.48; 95% CI: 0.31-0.74; p=0.0007). After Cox regression to adjust for potential confounding factors, the presence of complications during transport remained associated with hospital mortality (HR: 6.74; IC 95%: 1.40-32.34; p=0.017), however, was not associated with hospital discharge rates (HR: 0.76; 95% CI: 0.49-1.16; p=0.213). Conclusions: The complications were common during pediatric transport. Distance greater than 100 km, presence of respiratory disease, associated comorbidity and weight <10 kg were risk predictors for occurrence of complications. Complications during pediatric transport were associated with increased hospital mortality rates.

Les professionnels du transport maritime pétrolier doivent répondre à de multiples questions qui s'articulent principalement autour du renouvellement d'une flotte assez âgée, et en partie obsolète, face aux nouvelles normes de sécurité exigées par les organisations internationales. Le principal défi à relever repose alors sur les décisions d'investissements et de désinvestissements en phase avec les aspects cycliques du marché : type de navire, mode de financement ou d'exploitation. L'objectif principal est mettre en place un outil de prospective du marché du transport maritime. L'approche adoptée s'inscrit dans un schéma d'équilibre partiel ou le taux de fret est défini par l'égalité de l'offre et de la demande de transport qui est évaluée à l'aide d'une technique d'optimisation. L'offre de transport est estimée à l'aide d'un modèle économétrique. La méthodologie adoptée s'appuie sur un modèle dynamique ou la demande et l'offre sont estimées séparément. L'outil élaboré donne des prévisions, à l'horizon 1994, 1995 et 1996, des besoins, de l'offre de transport. Des taux de fret et des prix des naviresThe world shipping industry is facing a time of decision in the tanker sector and the stakes are much higher than they have been for a long time. A massive tanker-replacement program is inevitable and the main challenge involves handling oil transportation efficiently, with the necessary safety at acceptable prices. The purpose of this is to set a tool which explore the major factors that play an important role in explaining demand and supply of product tankers. It is a detailed examination of parameters for evaluating investment and strategies. An optimisation method is used to estimate product movements. We use an aggregated econometric model to estimate the available fleet. We assume that ship owners maximise profits under conditions of perfect competition. Freight rates are then obtained using the interaction of transport supply and demand. This model produce forecasts of spot rates and ship up to 1994, 1995, 1996

Brazil's cities in recent decades have a predominance of car use as children's mode of transport to school. In carrying out the route home-school by motorized modes children practice less physical activity to the detriment of health. Policies developed in schools can play an important role in determining how students travel to school. In this context, this research aims to identify the factors that influence the perception of managers about using the walk to access the school. The focuses of the research are the municipal and private elementary schools 1. The case study was conducted in the city of São José do Rio Preto. Data collection was carried out with the school managers (directors, coordinators and teachers) through questionnaires on travel behavior of the students, information on any activities at school to teach students to behave in traffic, opinions of management on the relationship between physical activity and health of children, children's ability to to walk to school, the barriers surrounding the school and attitude of managers regarding the use of different modes of transport and the impact of vehicle traffic in urban . The results showed that the estimation of directors and coordinators on the modes of transport used by students does not differ from a survey conducted by teachers significantly, and in private schools motorized individual transport is the most used by students and public schools over half of students walk or use public transportation to school. It was found that the traffic behavior on teaching is applied in all schools, although the directors and coordinators are more likely to say that the activities are carried out in your school. The school managers have a positive perception of the importance of physical activity, with acceptance rates above 90%. There is no consensus about the best age and abilities of children to make safe decisions alone and analysis on the perception of managers of barriers around the schools that may hinder access to foot it was found that about half of the managers have positive about the quality of the environment around the schools, but other managers have indifferent opinion about the quality of the environment. Regarding the use of different modes of transport it was observed that attitudes regarding the use of buses are in general negative, more than half of managers are indifferent to automobile use and favorable to the use of the walk. In the manager's attitude regarding the impact of vehicle traffic in urban areas the vast majority of managers are concerned about the impact of traffic on the environment. Perceptions regarding the active mobility should be worked through school policies to improve students' skills as pedestrians and through public policies to improve the environment in the school environment and encourage the use of active modes of transportation.
As cidades brasileiras nas ultimas décadas vem apresentando um predomínio do uso do automóvel como modo de transporte das crianças para a escola. Ao realizarem o percurso casa-escola por modos motorizados as crianças praticam menos atividades físicas com prejuízo para a saúde. Políticas desenvolvidas nas escolas podem desempenhar um papel importante na determinação do modo como os estudantes viajam para a escola. Neste contexto, esta pesquisa visa identificar quais os fatores que influenciam na percepção dos gestores sobre a utilização da caminhada para acesso a escola. O foco da pesquisa são as escolas municipais e particulares de ensino fundamental 1. O estudo de caso foi realizado na cidade de São José do Rio Preto. A coleta de dados foi realizada junto aos gestores escolares (diretores, coordenadores e professores) através de questionários sobre comportamento de viagem dos alunos da escola, informações sobre eventuais atividades desenvolvidas na escola para ensinar aos alunos com se comportar no trânsito, opiniões dos gestores sobre o relacionamento entre atividades físicas e saúde das crianças, a habilidade das crianças para caminharem até a escola, as barreiras existentes no entorno da escola e atitude dos gestores com relação à utilização dos diferentes modos de transporte e ao impacto do tráfego de veículos no meio urbano. Os resultados mostraram que a estimativa dos diretores e coordenadores sobre os modos de transporte utilizados pelos alunos não difere significativamente do levantamento realizado pelos professores, sendo que nas escolas privadas o transporte individual motorizado é o mais utilizado pelos alunos e nas escolas públicas mais da metade dos alunos caminham ou utilizam o transporte coletivo para a escola. Verificou-se que o ensino sobre comportamento no trânsito é aplicado em todas as escolas, embora os diretores e coordenadores sejam mais propensos a afirmar que as atividades são realizadas em sua escola. Os gestores escolares têm percepção positiva sobre a importância da atividade física, com taxas de aceitação acima de 90%. Não há um consenso sobre a melhor idade e as habilidades das crianças para tomar decisões seguras sozinhas e nas análises sobre a percepção dos gestores das barreiras existentes no entorno das escolas que podem dificultar o acesso a pé constatou-se que cerca da metade dos gestores tem opinião positiva sobre a qualidade do ambiente no entorno das escolas, porém os demais gestores possuem opinião indiferente quanto a qualidade do ambiente. Com relação à utilização dos diferentes modos de transporte observou-se que as atitudes com relação ao uso do ônibus são em geral negativas, mais da metade dos gestores são indiferentes ao uso do automóvel e são favoráveis às caminhada. Na atitude do gestor com relação ao impacto do tráfego de veículos no meio urbano a grande maioria dos gestores é preocupada com o impacto do tráfego no meio ambiente. As percepções com relação à mobilidade ativa devem ser trabalhadas através de políticas escolares para melhorar as habilidades dos alunos quanto pedestres e através de políticas públicas para melhorar o ambiente no entorno escolar e incentivar o uso dos modos ativos de transporte.

Le fonctionnement parallèle des réseaux des flux des envois et des informations dans la chaîne de production du transport express était le cas idéal pour identifier l’avantage concurrentiel que le système d’information crée pour l’entreprise. Le système d’information de l’entreprise de transport express peut être considéré comme un système d’information stratégique (SIS) parce qu’il soutient très bien les cinq coups stratégiques. Son rôle dans les stratégies de différenciation et de réduction des coûts est déterminant et son absence constitue un facteur de limitation non seulement pour les stratégies d’innovation, de croissance et d’alliances, mais aussi pour l’activité de l’entreprise. Si le système d’information est essentiel pour définir la démarche stratégique de l’entreprise de transport, il est en même temps défini par la stratégie de l’entreprise. Une boucle dynamique entre système d’information et démarche stratégique est ainsi produite : chaque élément de la boucle évolue sous l’influence de l’autreThis thesis gives weight to the importance of information and telecommunication technologies for the transport companies, by examining the information system in the context of the company’s strategy process. Parallel functioning of shipments and information flow networks inside the express transport production chain was the ideal case for the identification of the competitive advantage that information system creates for the company. The information system of the express transport company can be considered as a strategic information system (SIS) because it supports very well the five strategic thrusts. Its role for differentiation and cost reduction strategies is very important and its absence is a limiting factof not only for innovation, growth and alliances’strategies but also for the company activity. The information system has a strategic importance for the definition of the strategy process of the company and at the same time is defined by the company strategy. A dynamic loop between information system and strategy process is produced in this way : each element of the loop evolves under the influence of the other

This paper on the environmental impacts of transport purchasing in road freight is to highlight how the adaptive capability of transport chains are affected through collaboration and the aim for sustainability through political regulations and societal demands.This paper is divided into a theoretical framework and an empirical study, followed by the analysis, conclusions and discussions based on the framework and empirical study.The theoretical framework will discuss the different aspects of road freight transport which impact the environment and show the interdependencies of each aspect.The analysis will highlight the empirical chapter with a comparison of the theoretical framework in order to make substantial conclusions.Conclusions among others are that standardization is needed although flexibility and agility is also needed. By standardizing processes, routine measures can be implemented and it creates a sense of certainty within the company. Agility and flexibility can be achieved by adding modular processes which can be implemented if the need for customization arises.Governmental involvement is necessary for the development of infrastructure to minimize traffic congestion and improve the infrastructure for increased reliability, accessibility, and flexibility. By developing the rail infrastructure, a larger share of goods can be transferred via railway and thus reduce the environmental impacts of road freight through intermodal transportation.Program: Industrial Engineering – Logistics Management

When asked what the most important issue facing their country is, Chileans routinely refer to public transport systems. In the Santiago Metropolitan Region alone, the Transantiago system administers up to 6.400 buses covering a total area of 2400 km2 along 377 different routes. In spite of these numbers, it is increasingly evident that this system has failed. The Transantiago was implemented following a request for proposals published in 2005. The main objective of this Thesis is to help solve the mobility problems of the inhabitants of Santiago de Chile. As such, we started with a detailed analysis of the Transantiago in its current form. Furthermore, we examined its origins and history in order to better understand the causes of its problems and to find scope for improvement.

Full textAbstract:
Esta pesquisa foi motivada pela necessidade de desenvolvimento de uma metodologia para elaboração de índices de preços para os fretes de cargas agroindustriais no Brasil. O estudo das principais fórmulas utilizadas na elaboração dos índices culminou com a apresentação de um ranking segundo sua superioridade no atendimento às aproximações. Concluiu-se que os índices de Fisher e Walsh são aqueles capazes de atender ao maior número de preceitos lógicos, estatísticos e econômicos. Em seguida surgem os índices geométricos de Vartia, Törnqvist e Theil. Os índices de Laspeyres e Paasche, apesar de apresentarem algumas sérias limitações, acabam sendo amplamente utilizados na prática devido à fácil operacionalização. A pesquisa sobre os índices existentes para o transporte ratifica a idéia de que o Índice de Laspeyres é o mais utilizado. Essa análise ainda mostrou que os índices geralmente são elaborados com rotas bem definidas, para modais e tipo de carga bem definidos. A presente pesquisa apresentou um estudo de caso objetivando avaliar as variações nos procedimentos possíveis para a elaboração dos índices. A utilização de um estudo específico é justificada pela necessidade de se avaliar empiricamente os resultados obtidos a partir de índices distintos. Nesse sentido, foi escolhido o transporte rodoviário da soja a granel no Brasil. Foram realizados quatro tratamentos. Os tratamentos 1 e 4 mostraram-se mais adequados para a obtenção de um índice para o nível geral de frete. O primeiro, entretanto, apresenta baixa capacidade em fornecer informações mais desagregadas (sub-índices), uma vez que apresenta apenas agrupamento por faixas de distância. O quarto tratamento, por utilizar equações do preço em função da distância, deve ser considerado com ressalvas no fornecimento de sub-índices específicos. A principal vantagem que se espera desse tratamento é o conhecimento do nível geral dos preços sem perda de informações. Esse tratamento, sob o ponto de vista das aproximações, parece bastante razoável: atende à maior parte dos testes axiomáticos, está baseado em fundamentos estatísticos sólidos e utiliza uma função econômica que, estimada, fornece uma relação entre preço e quantidade. Os tratamentos 2 e 3, por sua vez, procuraram, por meio da desagregação, dispor de uma maior riqueza de informações, apresentando sub-índices por faixas de distância e regiões de origem e destino. Contudo, essa vantagem implica um esforço significativamente maior no processo de amostragem. A principal conseqüência de se trabalhar com informações incompletas é a ocorrência de sérias distorções (vieses) nos resultados finais.Em termos de informações para ponderação, foram testadas duas possibilidades: uma através da utilização da própria amostra (a distância percorrida), outra com o uso de informações exógenas (no caso, de uma matriz origem-destino que foi construída para esse fim). Recomenda-se a utilização de matrizes origem-destino, baseando-se no argumento de que isso diminuiria a responsabilidade sobre o processo amostral que, além dos preços, deveria também abranger as quantidades movimentadas. A realização da pesquisa permitiu a obtenção da variação acumulada no nível geral de preços para o transporte rodoviário de soja no Brasil no período entre fevereiro de 1998 e março de 2002. De acordo com os resultados dos tratamentos 1 e 4, essa variação teria sido de 76%.This research was motivated by the necessity of developing a methodology to elaborate price indexes to cargo freights for agroindustrial products in Brazil. The study on the most used mathematical formulas to elaborate indexes resulted in a ranking that considers their superiority in terms of theoretical approximations. It was concluded that Fisher and Walsh indexes are those that attend most of the logical, statistical and economic principles, followed by the geometric indexes, like Vartia, Törnqvist and Theil. Laspeyres and Paasche, in spite of their limitations, are widely used in practice. The research on the existing transportation indexes ratifies the idea that the Laspeyres is the most used. The analysis also showed that these indexes are generally calculated considering well-defined routes to specific transportation modes and cargoes. A case study was selected to evaluate variations on possible procedures to index elaboration. The utilization of a specific study is justified by the need of empirically evaluating the results to be obtained through different indexes. In view of that, it was chosen the bulk soybean hauled by road transport in Brazil. Four treatments were conducted. The treatments 1 and 4 seemed to be more suitable to calculate an index for a general price level. The first one, nevertheless, shows low capacity to supply less aggregated information, provided that has only items related to different distances groups. The fourth, which uses equations of price in function of distance, should be carefully considered when referring to sub-indexes transparency. The main advantage of this treatment is the knowledge of general price level without information loss. This treatment, under the theorical approach, looks quite reasonable: it attempts to the majority of axiomatic tests, is based on statistics foundation and uses an economic function that, when estimated, gives the relation between price and quantity. The treatments 2 and 3, in their turn, try to rank more information through disaggregation, showing sub-indexes for distances groups and origin and destination regions. On the other side, this advantage causes the need of significantly more efforts (large number of observations) in sampling process. The outcome of incomplete information is the occurrence of distortion (errors) in final results. Related to the weighting system, two possibilities were tested: using the own sample as the main source (traveled distance), or using exogenous information (in this case, from an origin-destination matrix built for this purpose). Its recommended the employment of origin-destination matrixes, based on the argument that this would reduce the responsibility over the sampling process that, beyond the prices, should comply the volumes that were transported. As a result, it was obtained that the general price level variation of the soybean transported by road in Brazil, between February 1998 and March 2002, was 76%, considering the treatments 1 and 4.

Full textAbstract:
High urban transport energy consumption is directly influenced by the level of transport energy dependence of urban forms and transport systems. Despite the introduction of new land use policies and vehicle technologies, dramatic reductions in urban transport energy dependence are not yet being observed. It is proposed that stricter land use regulations coupled with new GIS tools are required that specifically tackle the energy dependence issue. The objective of this project is to design a GIS tool that could be used within an urban development framework to dramatically reduce urban transport energy dependence. A tool was developed and named the Transport Energy Specification (TES). The TES measures urban transport energy dependency from travel behaviour, mode use and spatial data inputs. The TES is designed to be used as an energy based land-use regulation inside an urban development framework by specifying a maximum allowable energy dependency limit for land use modifications in existing urban areas and new developments. Implementation of the energy dependency land use regulation will be achieved through zoning and providing financial or other incentives for the specific desired land use activities (residential, supermarkets, kindergartens etc.). Trials were performed in Germany, New Zealand and Brazil, allowing different urban neighbourhoods and transport systems to be measured with the TES energy dependency measurement tool. The measurements confirmed similar findings from previous researchers regarding the benefits of high density areas and mixed activities in urban areas. Further analysis, trials and workshops with local governments will set in motion the process of including the TES into future urban development policy.O alto consumo de energia nos transportes urbanos é diretamente influenciado pelo grau de dependência energética das formas urbanas e dos sistemas de transportes. Como o desenvolvimento de novas tecnologias veiculares e políticas de uso do solo ainda não foi capaz de produzir reduções significativas no grau de dependência energética dos transportes urbanos, defende-se aqui que uma legislação mais restritiva de uso do solo, combinada com novas ferramentas de Sistemas de Informações Geográficas, constitui-se em uma condição necessária para enfrentar a questão da dependência energética. O objetivo deste projeto é desenvolver uma estrutura conceitual em plataforma SIG, que possa ser usada como ferramenta de planejamento para o desenvolvimento urbano, capaz de reduzir drasticamente a dependência energética do transporte urbano. A ferramenta desenvolvida recebeu a designação Especificação de Energia para Transporte (ou TES, da sigla em inglês Transport Energy Specification), e destina-se a medir o nível de dependência do transporte urbano em relação a aspectos como o comportamento de viagens, escolha modal e aspectos espaciais dos elementos urbanos. A TES foi concebida para ser usada como elemento regulatório do uso do solo, sob o ponto de vista da eficiência energética, a partir da especificação de um valor máximo para o limite de dependência energética decorrente de modificações em áreas urbanas existentes ou em novos loteamentos. A implantação de uma estratégia de regulação de uso do solo baseada no conceito de dependência energética pode ser alcançada através de uma legislação de zoneamento e de incentivos, inclusive financeiros, para determinadas tipos de uso (residências, supermercados, creches, etc.). Estudos de caso com a ferramenta proposta para avaliação do grau de dependência energética foram conduzidos em cidades selecionadas na Alemanha, Nova Zelândia e Brasil, de forma a contemplar diferentes tipos de arranjos de vizinhança e de sistemas de transportes. Os resultados encontrados confirmaram os benefícios, já apontados por outros pesquisadores, de áreas com elevadas densidades e uso misto em zonas urbanas. Novas análises, estudos de caso e discussões com governos locais são necessários para fazer do TES parte de políticas futuras de desenvolvimento urbano.

Ce mémoire présente les résultats de projets d'optimisation de réseaux de transport de l'entreprise Produit Forestier Résolu (PFR). Ces réseaux traitent, dans un cas, du transport de bois brut inter-usine et dans l'autre, de l'approvisionnement et du transport de copeaux vers les papetières. Le projet du transport de bois brut inter-usine cherche à développer un outil d'optimisation pour effectuer la planification du transport du bois brut entre les différentes étapes de production, soit le sciage, le séchage et le planage. Ce projet s'avère nécessaire en raison du contexte opérationnel de PFR, qui possède plusieurs petites usines avec des capacités différentes à chaque étape, demandant donc le transport de produits à différents moments. Le projet se restreint au territoire du Lac Saint-Jean, au Québec. Ce projet est complexe notamment en raison de la gestion des chargements; comme il s'agit de paquets de bois de toutes longueurs et dimensions, il n'est pas possible de simplement considérer une caractéristique physique pour remplir le camion. Les résultats sont prometteurs et proposent, outre une réduction significative du temps de planification, des gains allant de 1200 à 3000$ pour une période de deux semaines. Du côté du transport de copeaux, l'objectif est également de créer un outil d'optimisation, cette fois pour gérer l'approvisionnement en copeaux des papetières de PFR à travers la province de Québec. Ici, le défi est de considérer les recettes de productions aux papetières et d'assurer l'approvisionnement en tenant compte des différents mélanges d'essences aux scieries et les contraintes d'entreposage aux papetières. En raison de l'ampleur du réseau, les résultats sont significatifs, proposant des gains allant de 180 000 à 475 000$ pour une période de 4 semaines, en plus de faciliter la production de différents scénarios étudiant diverses hypothèses.

The electronic material graphene has attracted much attention for its unique physical properties such as, linear band structure, high electron mobility, and room temperature ballistic conduction. The possibilities for device applications utilizing graphene show great variety, from transistors for computing to chemical sensors. Yet, there are still several basic physical properties such as thermal conductivity that need to be determined accurately.
This work examines the thermal properties of graphene grown by the chemical vapor deposition technique. The thermoelectric power of graphene is studied in ambient and vacuum environments and is shown to be highly sensitive to surface charge doping. Exploiting this effect, we study the change in thermoelectric power due to introduction of gaseous species. The temperature dependent thermal conductivity of graphene is measured using a comparison method. We show that the major contribution to the thermal conductivity is the scattering of in-plane phonons.
Graphene also shows promise as an optoelectronic material. We probe the Landau level structure of graphene in high magnetic fields using a differential photoconductivity technique. Using this method we observed the lifting of spin and valley degeneracies of the lowest Landau level in graphene.

Full textAbstract:
This thesis studies a specific transport planning problem, which is based on a realistic scenario in the transport industry and deals with the delivery of goods by transport companies to their customers. The main aspect of the planning problem is to consider if each company should deliver the cargo on its own or through a collaboration of companies, in which the companies share the deliveries. In order to find out whether or not collaboration should take place, the transport planning problem is represented in terms of a mathematical optimization problem, which is formulated by using a column generation method and whose objective function involves minimization of costs. Three different solution cases are considered where each of them takes into account different combinations of vehicles used for delivering the cargo as well as the different maximum allowed driving time of the vehicles. The goal of the thesis is twofold; firstly, to see if the optimization problem can be solved and secondly, in case the problem is solvable, investigate whether it is beneficial for transport companies to collaborate under the aforementioned circumstances in order to incur lower costs in all instances considered. It turns out that both goals are achieved. To achieve the first goal, a few simplifications need to be made. The simplifications pertain both to the formulation of the problem and its implementation, as it is not only difficult to formulate a transport planning problem of this kind with respect to real life situations, but the problem is also difficult to solve due to its computational complexity. As for the second goal of the thesis, a numerical comparison between the different instances for the two scenarios demonstrates that the costs according to collaborative transport planning turns out to be considerably lower, which suggests that, under the circumstances considered in the thesis, collaboration between transport companies is beneficial for the companies involved.

Full textAbstract:
Cette thèse met en valeur l'importance des technologies de l'information et des télécommunications pour les entreprises de transport, en examinant le système d'information dans le contexte de la démarche stratégique de l'entreprise. Le fonctionnement parallèle des réseaux des flux des envois et des informations dans la chaîne de production du transport express était le cas idéal pour identifier l'avantage concurrentiel que le système d'information crée pour l'entreprise. Le système d'information de l'entreprise de transport express peut être considéré comme un système d'information stratégique (SIS) parce qu'il soutient très bien les cinq coups stratégiques. Son rôle dans les stratégies de différenciation et de réduction des coûts est déterminant et son absence constitue un facteur de limitation non seulement pour les stratégies d'innovation, de croissance et d'alliances mais aussi pour l'activité de l'entreprise. Si le système d'information est essentiel pour définir la démarche stratégique de l'entreprise de transport, il est en même temps défini par la stratégie de l'entreprise. Une boucle dynamique entre système d'information et démarche stratégique est ainsi produite: chaque élément de la boucle évolue sous l'influence de l'autre.

O sector dos transportes é crucial nesta àrea: não só é um dos sectores mais poluentes como um importante elo na cadeia de valor das empresas, contribuindo para as emissões de CO2 dos seus produtos. O presente estudo analisou a oferta ecológica que o sector do transporte expresso oferece em Portugal e procurou perceber se esta é valorizada pelas empresas na escolha do transportador. As principais conclusões sugerem que os operadores de transporte expresso apresentam já algumas iniciativas e soluções ecológicas, no entanto estas não são um critério primordial das empresas na selecção da transportadora, valorizando antes questões relacionadas com preço e eficiência.

The transport industry is crucial in this area: not only is one of the most polluting sectors as an important link in company?s value chain, contributing to the CO2 emissions of their products. The present study examined the ecological offer of the express transport sector in Portugal and sought to understand whether this is valued by companies in the choice of the carrier. The main findings suggest that transport operators already share some initiatives and environmental solutions; however these are not primary criteria to companies when selecting a carrier partner, emphasizing issues related to price and efficiency.

Full textAbstract:
El crecimiento económico y social que afronta el país en la actualidad ha traído como resultado un gran incremento de la demanda de viajes en las zonas urbanas de Lima Metropolitana; esto se ve reflejado en el incesante aumento de transporte privado y público, lo que da a lugar a la congestión vehicular, diversos accidentes de tránsito y elevados niveles contaminación ambiental y sonora. El flujo vehicular ha aumentado, no solo en avenidas principales, sino también calles secundarias, por vehículos particulares y de transporte público debido a que el parque automovilístico en el Perú ha aumentado en estos últimos años. Llegando a alcanzar hasta Julio del año 2018 un aumento del 5.5% anual, así lo indica el informe técnico N°09 de la INEI y el MTC. Es por esta razón que es necesaria la implementación de otras alternativas para el transporte privado y que sirva como apoyo al transporte público. La importancia de establecer una solución al importante tráfico que se vive en las calles diariamente ha concluido en la utilización de la bicicleta como medio de transporte cotidiano. En los últimos años, ciudades como Bogotá, en Colombia y Santiago en Chile han logrado que la bicicleta pase ser un modo de transporte recreativo a ser también un modo de transporte urbano cotidiano y eficiente. Sin embargo, Lima ha mantenido el porcentaje de personas que usa la bicicleta, ya sea de manera recreativa o laboral, en un 0.5% de la población, según el FONAM. Asimismo, los 150 km de ciclovía establecidas hasta la actualidad presentan falta de funcionalidad, planificación y deficiencia en el diseño geométrico de la interconectividad entre estas. Por lo tanto, en la presente tesis se analizará la aceptación de una ciclovía que conecte las estaciones de la Av. Angamos de dos medios de transporte masivo como lo son el Metro y el Metropolitano de Lima y se propondrá una ruta que cumpla con las bases de tiempo, infraestructura y accesibilidad de manera que cumpla eficientemente las necesidades de los usuarios de llegar a tiempo.The economic and social growth that the country is facing nowadays has resulted in an unceasing increase in the demand for travel in the urban areas of Metropolitan Lima; This is reflected in the constant increase in private and public transport, which leads to high traffic congestion, accidents, environmental pollution and noise. The traffic flow has increased, not only in main avenues, but also secondary streets, by private vehicles and public transport because the automobile fleet in Peru has increased in recent years. Reaching until July of 2018 an increase of 5.5% per year, as indicated in the technical report N ° 09 of the INEI and the MTC. It is for this reason that it is necessary to implement other alternatives for private transportation and to serve as a support to public transport. The importance of establishing a solution to the important traffic that lives on the streets daily has ended in the use of the bicycle as a means of daily transport. In recent years, cities such as Bogotá, Colombia and Santiago in Chile have made cycling a recreational mode of transport and also a daily and efficient mode of urban transport. However, Lima has maintained the percentage of people who use the bicycle, either recreationally or work, in 0.5% of the population, according to the FONAM. Likewise, the 150 km of bikeways established to date present lack of functionality, planning and deficiency in the geometric design of the interconnectivity between them. Therefore, in this thesis will be analyzed the acceptance of a bikeway that connects the stations of Av. Angamos of two means of mass transport as they are the Metro and the Metropolitan of Lima and a route that complies with the bases will be proposed of time, infrastructure and accessibility in a way that efficiently meets the needs of users to arrive on time.

We tested the existence of an intracellular nucleoside transporter pool in sheep reticulocytes. The number of cell surface NBMPR binding sites in sheep reticulocytes is 5.1 $ pm$ 0.5 (S.D.) fmol/10$ sp{6}$ cells (n = 9), compared to 6.9 $ pm$ 0.4 (S.D.) fmol/10$ sp{6}$ cells (n = 9) for total binding. Resealed ghosts made from sheep reticulocytes show no fewer NBMPR binding sites than cell surface, but somewhat fewer than total binding sites. Furthermore, the number of NBMPR binding sites is the same in ghosts $ pm$ saponin, suggesting that after cell lysis and resealing, NBMPR is accessible in the intracellular matrix. The resealed ghosts also show increased permeability to pCMBS (an inhibitor of -SH groups on the cytoplasmic side of the nucleoside transporter in sheep reticulocytes). NBMPR binding sites exhibit a preferential loss compared to those on the cell surface during in vitro maturation of sheep reticulocytes. Species differences in NBMPR binding on cell surface and total were also examined.

Full textAbstract:
The mitochondrial folate transport protein (MFT) functions to transport folates into the mitochondrial matrix. The MFT is a member of a mitochondrial carrier family (MCF) of proteins that have a high degree of sequence and structural similarities, yet they transport vastly different substrates at high specificities. In this dissertation research, the folate-specific transport mechanism of the MFT was explored using experimental and computational techniques. MFT residues that differed from MCF consensus residues in conserved PxD/ExxK/R motifs and at a predicted substrate-binding site common to all MCF proteins were investigated. Site-directed mutagenesis of these anomalous residues in the MFT revealed that these residues were adapted for optimal folate transport, and that the MCF consensus residues at these positions were incompatible with folate transport. The structure of the MFT was predicted by homology modeling using the solved crystallographic structure of the ADP/ATP carrier as a template and this model was subjected to ~75 ns of molecular dynamics simulations. These simulations predicted a stepwise descent for the folate substrate into the MFT transport cavity and implicated several aromatic and basic residues in folate recognition and orientation. A predicted set of interactions at the base of the transport cavity between the MCF PxD/ExxK/R conserved motif residues did not appear static as previously hypothesized; these interactions appeared to be induced in the presence of the folate substrate. Therefore, we believe it is unlikely that these interactions form a barrier at the base of the transport cavity. We also investigated the role of the MFT in the compartmentalization of folate metabolism. Cell lines were created that could be induced with doxycycline to express either the cytosolic or mitochondrial isoform of the enzyme folylpoly-γ-glutamate synthetase (FPGS). The constructed cell lines were used to study the flux of folylpolyglutamates across the mitochondrial membrane. It appeared that cellular folylpolyglutamates are not transported across the mitochondrial membrane in either direction. We also demonstrated that many antifolates, including methotrexate and pemetrexed, impaired mitochondrial folate uptake. We believe that these folate analogs competitively inhibit the MFT and have purified the MFT protein for future analysis in reconstituted transport systems.

Full textAbstract:
Le droit des transports ferroviaires est marqué, en Europe, par l'ampleur du réseau ferroviaire paneuropéen sous l'égide de l'Organisation de transports internationaux ferroviaires assortie de son corps normatif dans sa version de 1980, qui recouvre quarante-deux Etats sur trois continents, amcain, asiatique et européen, pris au sens géographique. Avec l'avènement du nouveau corpus normatif institué par le protocole de Vilnius de 1999, ce système juridique novateur entre en vigueur en juillet 2006 à raison de vingt-sept premières adhésions étatiques. Le recours par les transporteurs ferroviaires qui n'auront pas, ou pas encore, adhéré au nouveau système, nouveau système qui aspire à la libéralisation des transporteurs ferroviaires, à des dispositions de droit contractuel pour se soumettre au droit réformé par ce biais, est une solution envisagée à un éventuel démembrement du réseau du fait d'adhésions manquantes, dans l'intérêt de l'uniformisation juridique du réseau ferroviaire paneuropéen, pour autant que le droit contractuel demeure assujetti au droit national contraignant respectif. Le rapprochement des normes nationales internes aux dispositions à caractère international de la COTIF diverge d'un Etat à l'autre, avec parfois des insertions de normes internationales relevant de l'OTIF en droit interne comme des dispositions procédurales singulières très spécifiques. Si l'on veut bien se référer au modèle préalable britannique pour ce qui est de la libéralisation du secteur ferroviaire, les expériences du passé permettant de mieux comprendre l'avenir, il semble que le principe d'obligation de transporter demeure du fait de nécessités commerciales, avant comme après la libéralisation, la mission de service public persistant en droit des transports ferroviaires. Malgré la démarcation qui demeure entre elles d'après les réalités historiques allant au-delà de l'Union de Berne de 1890, les deux organisations internationales de transport ferroviaire que sont l'OSJD axée sur l'Europe orientale et sur le continent asiatique autour de la Communauté des Etats Indépendants, et l'OTIF plus axée géographiquement sur une zone ferroviaire occidentale, réalisent un effort remarquable d'harmonisation qui sert l'intérêt du réseau ferroviaire paneuropéen. A l'appui de ces efforts viennent s'adjoindre ceux de la Communauté européenne qui, d'une part, se propose d'instituer en ce sens, outre ses directives, des règlements européens et, d'autre part, envisage avec sérieux son adhésion à l'OTIF. Cette évolution va dans le sens d'une uniformisation juridique réellement souhaitée mais praticable seulement à long terme.

Full textAbstract:
La tesis presenta una descripció unificadora d'una varietat d'experiments de transport tèrmic a la micro i nano escala en semiconductors com el silici o el germani. S'utilitza un model de transport de calor hidrodinàmic per predir la resposta no difusiva de sistemes complexes en situacions de rellevància tecnològica, com el procés de refredament d'un component electrònic alliberant calor cap a un substrat semiconductor. El model no utilitza paràmetres d'ajust en funció de la geometria, sinó que utilitza paràmetres calculats des de primers principis. Els efectes de mida petita o alta freqüència es capturen a través de condicions de contorn específiques i, per tant, el model és una eina útil pel disseny de dispositiu micro electrònics. Degut a que la descripció hidrodinàmics pel silici no és el mètode convencional, en aquesta tesis es posa especial èmfasis en determinar l'aplicabilitat del model en múltiples experiments de manera unificadora. Com a resultat, s'identifiquen fenòmens no difusius com la propagació del segon so en camps tèrmics fluctuants en germani o múltiples temps de relaxació en l'evolució tèrmica d'escalfadors nano estructurats en silici. A més, la descripció hidrodinàmica es compara amb altres models moderns per descriure els mateixos experiments, i es proporciona un resum de les eines teòriques necessàries (la termodinàmica de no equilibri i la teoria cinètica). Utilitzant les evidències experimentals que s'aporten, es conclou que el model hidrodinàmic té capacitat predictiva de la resposta tèrmica de materials com el silici a la nano escala dins d'un cert rang d'aplicabilitat.Ésta tesis presenta una descripción unificadora de una variedad de experimentos de transporte térmico a la micro y nano escala en semiconductores como el silicio o el germanio.

Dado que la descripción hidrodinámica para el silicio no es el método convencional, en ésta tesis se presta especial atención a determinar la aplicabilidad del modelo en múltiples experimentos de forma unificadora. Como resultado, se identifican fenómenos no difusivos como la propagación de segundo sonido en campos térmicos fluctuantes en germanio, o múltiples tiempos de relajación en la evolución térmica de calentadores nano estructurados en silicio. Además, la descripción hidrodinámica se compara con otros modelos modernos para describir los mismos experimentos, y se proporciona un resumen de las herramientas teóricas necesarias (la termodinámica de no equilibrio y la teoria cinética). Utilizando las evidencias experimentales que se aportan, se concluye que el modelo hidrodinámico tiene capacidad predictiva de la respuesta térmica de materiales como el silicio a la nano escala dentro de un cierto rango de aplicabilidad.
This thesis presents a unifying description of a variety of experiments on micro- and nano-scale heat transport in semiconductors like silicon or germanium. A hydrodynamic-like heat transport model is used to predict the non-diffusive thermal response of complex systems in technologically relevant situations, like the process of energy release from nanostructured heat sources towards a semiconductor substrate. The model does not use geometry-dependent or fitted parameters, but use intrinsic material properties that can be calculated from first principles. Small-size and high-frequency effects are captured through the use of specific boundary conditions, thus resulting in a practical tool for complex microelectronic device design. Since hydrodynamic modeling is not the state-of-the-art approach to describe standard semiconductors like silicon, special care is devoted to quantitatively determine the applicability of the model, and multiple experiments using different techniques are considered and studied in a unifying way. As a result, previously unreported non-Fourier phenomena in materials like silicon or germanium is identified and demonstrated (e.g. second sound in rapidly varying thermal fields or multiple decay times characterizing the evolution of nano-structured heaters). Furthermore, the hydrodynamic description is compared with alternative modern frameworks describing size and frequency effects in semiconductor heat transport, and a summarized overview of the theoretical background, namely non-equilibrium thermodynamics and kinetic theory, is presented. In light of the extensive experimental evidence provided, this thesis demonstrate the predictive capability of hydrodynamic-like thermal transport modeling in semiconductors within a certain range of applicability that is well beyond the diffusive regime.
