     Um esqueitista treina em uma pista cujo perfil está representado na figura abaixo. O trecho horizontal AB está a uma altura h = 2,4 m em relação ao trecho, também horizontal, CD. O esqueitista percorre a pista no sentido de A para D. No trecho AB, ele está com velocidade constante, de módulo v = 4 m/s; em seguida, desce a rampa BC, percorre o trecho CD, o mais baixo da pista, e sobe a outra rampa até atingir uma altura máxima H, em relação a CD. A velocidade do esqueitista no trecho CD e a altura máxima H são, respectivamente, iguais a

    The Impact of the Gulf Oil Spill on the U.S.

          Although the oil has been pouring into the Gulf of Mexico for months, the consequences of this larger than ever environmental disaster have yet to be fully examined and determined. Scientists and researchers have started to put together some of the puzzle pieces, and the impact of the Deepwater Horizon oil spill are likely to be big.

          North Americans will have fewer choices on the store shelves. The Gulf of Mexico is a huge shipping lane through which products of all shapes and sizes come into North America. From toys to clothes to cars to building materials, you may find that the selection at your local store begins to shrink as shipping lanes slow down as a result of the oil spill.

          Whether you’re taking a vacation or hoping to walk along the shore, you may be disappointed. Many beaches in the U.S.A. are now closing as clean-up efforts on removing oil slick from the sands. But the impact may be felt for quite some time as oil continues to wash up on shore.

          Many wildlife animals will be impacted by the oil spill. Oiled birds, otter, bald eagles, pelicans, turtles, fish, and dolphins are already washing up on shore, making the beach sights less than palatable for someone looking to see some pristine nature.

          Over time, molluscs like clams incorporate calcium into their shells throughout their lifetimes. But the heavy metals like nickel and vanadium from the petroleum industry and the resulting oil spill may be incorporated into the shells of these creatures. As other wildlife consumes these clams, they incorporate the toxins into their bodies, and on it goes as the heavy metals bio-accumulate in the food chain. This could have serious, long-term consequences for human health. 

          Environmentalists have been working on restoring the populations of oysters by reseeding certain reefs to boost their numbers. The Gulf of Mexico has been home-working on some of these projects, but with the massive oil spilling into that environment, the oysters could soon become tainted with chemicals, making them unsafe to eat.

          The Gulf of Mexico is also a nursery for species like shrimp that grow up in the estuaries. The oil that is taking over this natural environment will choke out the plants that make the estuaries so nutritious to shrimp. 

          According to the National Weather Service, a hurricane like Hurricane Katrina could have a devastating impact on New Orleans. Researchers expect 15 named storms to develop into 8 hurricanes, and with a well-placed hurricane, the oil could be pushed onto New Orleans shores, further impacting the already devastated region.

    A formação de coágulos é um processo natural que impede a ocorrência de hemorragias, entretanto a coagulação no interior dos vasos obstrui a circulação sanguínea. O coágulo se forma devido à transformação de uma proteína denominada fibrinogênio em outra proteína em forma de uma rede de malhas finíssimas denominada fibrina, que estanca a hemorragia.

    A hipercolesterolemia familiar é uma doença genética associada à deficiência do metabolismo lipídico, nomeadamente o transporte e metabolismo do colesterol. É uma doença com transmissão autossômica dominante. Um indivíduo heterozigoto tem 50% de probabilidade de transmissão do alelo para seu descendente. Indivíduos homozigóticos para o alelo, geralmente, morrem em poucos anos de vida, devido à forma grave da doença, caracterizada por hipercolesterolemia precoce. A dieta alimentar, bem como outros hábitos vitais, pode controlar a doença.

    Em 1911, o renomado cientista Ernest Rutherford e seus colaboradores Marsden e Geiger realizaram uma série de experimentos com materiais que emitiam partículas alfa (α). Os resultados obtidos levaram esse pesquisador a sugerir um novo modelo para o átomo. A figura a seguir representa, esquematicamente, um desses experimentos.

    Sobre os motivos que levaram Rutherford a realizar esses experimentos e as conclusões que ele obteve, foram feitas as afirmações:

    I. Rutherford concordava com o modelo atômico sugerido por Thomson e, por isso, esperava que todas as partículas alfa(α) atravessassem a placa de ouro com facilidade.

    II. O modelo atômico proposto por Rutherford sugere que o átomo é eletricamente neutro, apesar de ser constituído por partículas positivas e negativas.

    III. Rutherford desenvolveu esses experimentos porque estudava o comportamento dos prótons e elétrons que constituem a placa de ouro.
