    A review of the status of bryological research in each of the nations, states or governmental units of southern Melanesia, Micronesia and tropical Polynesia shows the imperfect state of knowledge about the Pacific tropical islands. Best known overall are Hawaii and Micronesia with Wallis and Futuna, the Marquesas and the high mountains of Fiji seeming to be the least known potentially species rich areas. Involvement of residents from Pacific islands in botanical study and preservation of ecosystems should be encouraged by tropical bryologists

    Constant propellant use rendezvous scenario across a launch window for refueling missions

    Get PDF
    Active rendezvous of an unmanned spacecraft with the Space Transportation System (STS) Shuttle for refueling missions is investigated. The operational constraints facing both the maneuvering spacecraft and the Shuttle during a rendezvous sequence are presented. For example, the user spacecraft must arrive in the generic Shuttle control box at a specified time after Shuttle launch. In addition, the spacecraft must be able to initiate the transfer sequence from any point in its orbit. The standard four-burn rendezvous sequence, consisting of two Hohmann transfers and an intermediate phasing orbit, is presented as a low-energy solution for rendezvous and retrieval missions. However, for refueling missions, the Shuttle must completely refuel the spacecraft and return to Earth with no excess fuel. This additional constraint is not satisfied by the standard four-burn sequence. Therefore, a variation of the four-burn rendezvous, the constant delta-V scenario, was developed to satisfy the added requirement

    Reproductive anatomy and physiology of the bull (1990)

    "Good reproductive performance of a bull is necessary to obtain a high percent calf crop when natural service is used for breeding. A bull must be fertile, capable and willing to mate a large number of cows during a short breeding season for optimum production. A basic knowledge of the reproductive tract is beneficial for improved management. An understanding of the bull's reproductive system will also help the producer better understand breeding soundness examinations, reproductive problems and breeding impairments."--First page.New 3/90/5M

    Allergic Rhinitis: Treatment of a Seasonal problem

    Get PDF
    Allergic rhinitis affects up to 30% of the population yet there is evidence that it is under treated and misdiagnosed. Allergy symptoms closely mimic other common illnesses and most medication used to treat seasonal allergies is now available over the counter. This shift in therapy means that patients are now self-medicating with little knowledge of what they are actually treating. Therefore this project aims to clear common misconceptions that prevail in the general population of Vermont as well as provide some guidance on the types of medications used to treat seasonal allergies.https://scholarworks.uvm.edu/fmclerk/1074/thumbnail.jp
