13. Integração dos problemas de carregamento e roteamento de veículos com janela de tempo e frota heterogênea. / Integration of loading and vehicle routing problems with time windows and heterogeneous fleet.
Este trabalho aborda um problema ainda não explorado na literatura denominado 3L-FSMVRPTW (three-dimensional loading fleet sizing and mix vehicle routing problem with time windows), que compreende resolver simultaneamente o roteamento e carregamento tridimensional de veículos considerando frota heterogênea e janela de tempo. Foi desenvolvido um algoritmo

14. Dynamic generation metodology of road travel patterns to vehicles intelligent monitoring in AVL systems. / Metodologia de geração dinâmica de padrões de viagens rodoviárias para monitoramentos inteligentes de veículos de carga em sistemas AVL.
This dissertation addresses the question of vehicle travel adherence in intelligent monitoring with Automatic Transportation Location (AVL) operating in a regional environment. A trip is considered as series of runs, corresponding to time in movement but excluding time spent on activities such as loading/unloading and others. Based on historic data collected

15. Desenvolvimento de análise por trajetórias vibroacústicas para aplicação automotiva
An analysis and development of how vibration and acoustic noise generated in a motor car arrives at the interior of the vehicle, a key issue in modern industry, is presented. The study considers the development of experimental techniques, employing computational data processing and data systemising, leading to the identification and ranking contribution of b

16. Three-dimensional cutting and packing problems and integration with vehicle routing / Problemas de corte e empacotamento tridimensional e integração com roteamento de veiculos
The wide-scale adoption of the containers made the development of the multimodal transport possible. Nowadays, shipment of boxes in containers is an important activity for companies that have in the load transport a logistic factor of high cost. This work presents the development and the application of metaheuristics with adaptive memory in order to solve th

17. A DYNAMIC INTERACTION MODEL OF TRACK RAILWAY STRUCTURAL ELEMENTS / UM MODELO DE INTERAÇÃO DINÂMICA ENTRE OS ELEMENTOS ESTRUTURAIS DE UMA VIA FÉRREA
In a railway, the vehicle interacts dynamically with a track superstructure (rails, rail pad and sleepers) and sub-structure (ballast, sub-ballast, sub- grade). Passengers comfort, environmental loading (ground vibration) and frequency of maintenance works of vehicles as well as of the track are deter- mined by the way all the structural elements interact. T

18. Estudo da dinamica das transmissões mecanicas por trens de engrenagens planetarias
Vehicular transmissions are the way to adapt the torque supplied by the engine to that required at each moment of the path of a vehicle. Automatic gearboxes are among severa! types oftransmissions. Epicyclic Gear Trains, EGTs, are fundamental components ofthis kind of mechanical transmission. This kind of mechanism have been studied exhaustively trough the y

19. Abordagens para problemas de roteamento
Neste trabalho, investigamos abordagens para problemas de roteamento, que têm como finalidade encontrar um melhor conjunto de rotas para que veículos possam transportar mercadorias a clientes geograficamente dispersos, respeitando certas restrições, como por exemplo, a de capacidade de carga dos veículos. Para isto, além de pesquisas em diversas fontes

20. Interactions between angiotensin II, aortic and sympathetic nerve during development of coarctation hypertension. / Interações entre angiotensina II, atividade do nervo depressor aórtico e atividade simpática esplâncnina durante o desenvolvimento da hipertensão por coarctação.
In the chronic phase of coarctation hypertension (CH) we have shown both marked depression of baroreceptor reflex control of heart rate (Michelini et al, Hypertension, 1992, 19: II159-II163) and normalization of the depressed reflex control even with the persistence of hypertension in losartan-treated animals (Santos et al, Am. J. Physiol, 1995, 269: H812-H8

21. Calcineurin plays a modulatory role in loading-induced regulation of type I myosin heavy chain gene expression in slow skeletal muscle
The role of calcineurin (Cn) in skeletal muscle fiber-type expression has been a subject of great interest because of reports indicating that it controls the slow muscle phenotype. To delineate the role of Cn in phenotype remodeling, particularly its role in driving expression of the type I myosin heavy chain (MHC) gene, we used a novel strategy whereby a pr

22. Virus-assisted loading of polymer nanocontainer
We present a DNA-containing polymeric nanocontainer using the self-assembled superstructure of amphiphilic block copolymers in aqueous solutions. To demonstrate that DNA translocation is possible across a completely synthetic block copolymer membrane, we have used a phage transfection strategy as a DNA-transfer model system. For this purpose the bacterial ch

23. Transfer of tRNAs to somatic cells mediated by Sendai-virus-induced fusion.
tRNAs from yeast (tRNAPhe and 4S RNA) and Escherichia coli (suIII+ tRNAITyr) have been transferred to mouse cells by means of a two-step transfer procedure [Loyter, Zakai, and Kulka (1975) J. Cell Biol. 66, 292-304; Schlegel and Rechsteiner (1975) Cell 5, 371-379]. In the first stage of the transfer tRNAs were incorporated into rabbit red blood cells (RBCs).

24. Type 1 Diabetes in Young Rats Leads to Progressive Trabecular Bone Loss, Cessation of Cortical Bone Growth, and Diminished Whole Bone Strength and Fatigue Life
People with diabetes have increased risk of fracture disproportionate to BMD, suggesting reduced material strength (quality). We quantified the skeletal effects of type 1 diabetes in the rat. Fischer 344 and Sprague-Dawley rats (12 wk of age) were injected with either vehicle (Control) or streptozotocin (Diabetic). Forelimbs were scanned at 0, 4, 8, and 12 w
