Rapid Transport

A má qualidade do transporte público e da qualidade de vida, o crescimento do índice de acidentes e o aspecto visual desacolhedor, são alguns dos problemas que a expansão urbana acelerada sem planejamento nas cidades ocasiona. Em cidades de médio/grande porte é importante a realização de um projeto de Mobilidade Urbana, para evitar ou reduzir esses problemas, sejam eles ambientais, sociais ou econômicos. O propósito desse artigo foi analisar o projeto de Mobilidade Urbana realizado em Anápolis – GO, comparando com o Plano Diretor da cidade, com foco na principal e maior avenida: Avenida Brasil. O projeto contou com a implantação de corredores exclusivos para ônibus nas principais avenidas da cidade: Avenida Universitária, Pedro Ludovico, JK/São Francisco, Presidente Kennedy/Fernando Costa e Brasil, procurando a melhora na qualidade do sistema do transporte público, diminuindo o tempo gasto nas viagens, oferecendo segurança e conforto para os passageiros e, consequentemente, harmonizando a relação dos ônibus com os demais veículos no tráfego. O projeto também contou com a construção de novas plataformas de embarque e desembarque e dois viadutos localizados na Avenida Brasil sentido Sul. Ao ser realizada a comparação do Plano Diretor de Anápolis com a Avenida Brasil já em funcionamento com o novo Plano de Mobilidade Urbana, foi constatado que os pedestres, ciclistas e usuário de transporte público foram parcialmente favorecidos, ainda sem total prioridade no espaço viário. O Plano de Mobilidade Urbana realizado na cidade de Anápolis conseguiu antecipar a futura implantação do sistema BRT – Bus Rapid Transport, para quando houver demanda suficiente na cidade, pois os corredores exclusivos implantados, juntamente com as mudanças realizadas, não são o suficiente para que já seja considerado um sistema BRT.

A field experiment shows that rapid downward migration of solutes and microorganisms can occur in a fractured till. A solute tracer, chloride, and a bacteriophage tracer, PRD-1, were added to groundwater and allowed to infiltrate downwards over a 4 × 4 m area. Chloride was detected in horizontal filters at 2.0 m depth within 3-40 days of the start of the tracer test, and PRD-1 was detected in the same filters within 0.27 - 27 days. At 2.8 m depth chloride appeared in all the filters, but PRD-1 appeared in only about one-third of the filters. At 4.0 m depth chloride appeared in about one-third of the filters and trace amounts of PRD-1 were detected in only 2 of the 36 filters. Transport rates and peak tracer concentrations decreased with depth, but at each depth there was a high degree of variability. The transport data is generally consistent with expectations based on hydraulic conductivity measurements and on the observed density of fractures and biopores, both of which decrease with depth. Transport of chloride was apparently retarded by diffusion into the fine-grained matrix between fractures, but the rapid transport of PRD-1, with little dispersion, indicates that it was transported mainly through the fractures.

Basic Equipment

In aircraft and airport disasters help must reach the site of the accident in a very short time. In addition to the ground rescue service, rescue helicopters can also offer help. The rescue helicopter as a mobile intensive care unit contains a medical crew with a flying physician and a paramedic. The following are required basic equipment for rescue helicopters: resuscitation apparatus with and without oxygen; endotracheal intubation set; suction unit; apparatus for measuring blood pressure; infusion sets and solutions with intravenous cannulas; syringes and needles; bandages; special burn dressings; fixation and splinting material; vacuum mattress; surgical pocket kit; stomach tube; ECG monitor; defibrillator with pacemaker; drugs; and otoscope. This medical equipment has to be portable so that it can be used outside the rescue helicopter.The medical crew must be trained in emergency medical treatment and in aeromedical problems. Patients who are fit to fly can be transported by rescue helicopters after triage and support of their vital functions. This method is of most value if rapid transport to a distant specialized medical department, for example, to a burn or neurosurgery center, is required.The German Air Rescue operates seven rescue helicopters at five rescue helicopter centers for primary rescue with the helicopter types BO 105 CBS, BO 105, Bell 206 Long Ranger and 3et Ranger. Another important function of the service are long distance flights with patients to medical centers after aircraft and airport disasters. Specially equipped ambulance aircraft are used in these cases.

Potential Stability

The peculiarities of organization and perspectives of mass passenger transportation in the city and beyond are considered with the use of "Bus Rapid Transport" (BRT) or Metrobus. Different aspects of study of motor vehicles (MV) controllability and stability are analyzed. It is substantiated that it is sufficient to consider the potential stability of the MV itself, in order to guarantee the stability of the "driver MV" system with a large reserve. A mathematical model of a three-axle bus train consisting of a bus and two trains (metrobus) is developed and the factors influencing the critical speed as the main index of the stability of its movement are determined. It is established that the increase of the critical speed of the metrobus can be achieved by increasing the base of the bus, the first and the second trailer, as well as the mass of the bus and the coefficients of resistance of the drive wheels of the bus driving axle and the trailers axles. At the same time, increasing the distance from the mass center to the bus rear axle, increasing the distance from the mass center to the point of the coupling of the bus with the first trailer, increasing the mass of trailers and the resistance of the resistance of the wheel drive of the bus axis lead to a decrease in the critical speed of the metrobus. This must be taken into account both when designing metrobuses, and when operating them.

A single intracerebroventricular injection of dexamethasone (DEX) rapidly (within 30 min) suppresses brown adipose tissue thermogenesis and increases plasma insulin concentrations in adrenal-ectomized (ADX) ob/ob mice but not in ADX lean mice. Intracerebroventricular neuropeptide Y (NPY) administered intracerebroventricularly causes these same metabolic changes within 30 min in both ob/ob and lean ADX mice. We therefore hypothesized that DEX exerts these rapid-onset metabolic actions in ob/ob mice via a phenotype-specific enhancement of NPY secretion within the central nervous system. In support of this hypothesis, DEX (a type II glucocorticoid receptor agonist) administered intracerebroventricularly selectively lowered NPY concentrations in the whole hypothalamus of ADX ob/ob mice by 35% and in the arcuate nucleus region by approximately 70% within 30 min but not in the brain stem or hippocampus or in any of these regions of lean mice. DEX also functioned in vitro to enhance depolarization-dependent release of NPY from hypothalamic blocks of ADX ob/ob mice but not of ADX lean mice. Thus DEX acts in the hypothalamus of ob/ob mice in a phenotype-specific manner to evoke rapid transport of NPY from cell bodies within the arcuate nucleus to terminal regions including the dorsomedial and ventromedial hypothalamic regions for release.

Preferential Water

<p>Preferential water flow and solute transport in agricultural systems affects not only the quality of groundwater but also the quality of surface waters like streams and lakes. This is due to the rapid transport of agrochemicals, immediately after application, through subsurface drainpipes and surface water. Experimental evidence attributes this to the occurrence of continuously connected pathways, connecting the soil surface directly with the drainpipes. We developed a physically-based model describing preferential flow and transport in biopores and implemented it in the agroecological model Daisy. The model simulates the often observed rapid transport of chemicals from   the upper soil layers to the drainpipes or to deeper layers of the soil matrix. Based on field investigations, biopores with specific characteristics can be parameterized as classes with different vertical and horizontal distributions. The model was tested against experimental data from a column experiment with an artificial biopore and showed good results in simulating preferential flow dynamics. We illustrate the performance of the new approach, by conducting five simulations assuming a two-dimensional simulation domain with different biopore parametrizations, from none to several different classes. The simulation results agreed with experimental observations reported in the literature, indicating rapid transport from the soil to the drainpipes. Furthermore, the different biopore parametrizations resulted in distinctly different leaching patterns, raising the expectation that biopore properties could be estimated or constrained based on observed leaching data and direct measurements.</p>
