Development of a unified guidance system for geocentric transfer

A method is presented for open loop guidance of a solar electric propulsion spacecraft to geosynchronsus orbit. The method consists of determining the thrust vector profiles on the ground with an optimization computer program, and performing updates based on the difference between the actual trajectory and that predicted with a precision simulation computer program. The motivation for performing the guidance analysis during the mission planning phase is discussed, and a spacecraft design option that employs attitude orientation constraints is presented. The improvements required in both the optimization program and simulation program are set forth, together with the efforts to integrate the programs into the ground support software for the guidance system

The Cake Cafe Menu 2017

At the Cake Café we do birthday cakes, tasty cakes and party cakes, cakes for any occasion. [email protected] The Cake Café\u27s leafy courtyard has been an oasis in the city centre where people enjoy sugar-dusted sponges, lemon slices, the most excellent coffee, glasses of processco, baked egg & soldiers or our famous beans on toast. You will not find a microwave or freezer in our kitchen, everything is prepared fresh to order using the very best Irish produce and natural oils. We do everything that we can to support the excellent small food producers in Ireland. Our business is conducted in an environmentally friendly manner; even using rain water to flush our toilets.https://arrow.tudublin.ie/menus21c/1415/thumbnail.jp

Cake in the Country

This is a place where you can expect a lot of rambling mumblings about growing up in rural Ireland and the adventures that ensued. Twas great craic. Recipes included :) I spend my time at home mostly baking, on the farm, poring through my ever growing collection of books and cookbooks. Term time largely consists of poring through medical books and taking an occasional cooking break. Must mention that the first Friday of every month is now cookalong night with the Irish foodies. Please join in, even if it’s as simple as your own take of beans on toast! Find us on facebook here: http://www.facebook.com/group.php?gid=10271164644931

Larval Cestode Parasites of Edible Mollusks of the Northeastern Gulf of Mexico

Ten distinct species of larval cestodes were obtained from 43 edible, or potentially edible, benthic mollusks of the northeastern Gulf of Mexico. Three of the infected mollusks, American oysters, Crassostrea virginica (Gmelin), Atlantic bay scallops, Argopecten irradians concentricus (Say), and sunray venus clams, Macrocallista nimbosa (Lightfoot), are important commercial species in the eastern Gulf and the remainder are occasionally eaten by epicurean shellfishermen or were consumed by prehistoric, aboriginal Indians of the Gulf coast. The cestodes represent four orders, seven families and nine recogized genera and include the trypanorhynchs, Euteirarhynchus sp. (of Cake 1975) and Parachristianella sp. (of Cake 1975), the Iecanicephalideans, Polypocephalus sp. (of Cake 1975) and Tylocephalum sp. (of Burton 1963), the tetraphyllideans, Dioecotaenia cancellata (Linton 1890), Anthobothrium sp. (of Cake 1975), Rhinebothrium sp. (of Cake 1975), Acanthobothrium sp. (of Regan 1963), and Acanthobothrium sp. (of Harry 1969), and the diphyllidean, Echinobothrium sp. (of Cake 1975). Infected mollusks were widely distributed in coastal estuarine and marine habitats from the Mississippi Sound to the Florida Keys. Pelecypods appear to serve as primary intermediate hosts and molluscivorous gastropods appear to serve as secondary intermediate or paratenic (transport) hosts for these cestodes which in turn utilize demersal elasmobranch fish as final hosts. None of these cestodes are known to infect humans and the only potential harm is to the quality and quantity of the edible molluscan tissues

Experimental Infection Studies with Bothridio-Plerocercoids of Rhinebothrium sp. (Cestoda; Tetraphyllides) and Two Intermediate Molluscan Hosts

Molluscivorous gastropods became infected with bothridio-plerocercoids of the elasmobranch cestode, Rhinebothrium sp. (Cake, 1976) (Tetraphyllidea; Phyllobothriidae) after consuming infected pelecypods under experimental conditions. Banded tulips, Fasciolaria lilium hunteria (Perry)(Gastropoda; Fasciolariidae) exhibited a significant increase in infection intensity after consuming Rhinebothrium-infected viscera from ponderous arks, Noetia ponderosa(Say)(Bivalvia; Arcidae). The final experimental infection intensity was 144 times greater than the baseline intensity (43.2 vs. 0.3 plerocercoids/tulip) and 24 times greater than the final controlintensity (43.2 vs. 1.8/tulip). The experimental transmission rate was 20.6% of the probable rate based on a mean intensity of 33±6.9 plerocercoids/baseline ark. Marine pelecypods and gastropods appear to serve as intermediate and/or paratenic hosts in the life cycle of Rhinebothrium sp

Mass study for modular approaches to a solar electric propulsion module

The propulsion module comprises six to eight 30-cm thruster and power processing units, a mercury propellant storage and distribution system, a solar array ranging in power from 18 to 25 kW, and the thermal and structure systems required to support the thrust and power subsystems. Launch and on-orbit configurations are presented for both modular approaches. The propulsion module satisfies the thermal design requirements of a multimission set including: Mercury, Saturn, and Jupiter orbiters, a 1-AU solar observatory, and comet and asteroid rendezvous. A detailed mass breakdown and a mass equation relating the total mass to the number of thrusters and solar array power requirement is given for both approaches
