Parasitic InteriorsKanasink, Michael 27 April 2011 (has links)
This project is an experiment in the adaptive reuse of an Art Deco style manufacturing facility in Richmond, VA. The building has fallen into disrepair and has been inhabited by two different owners over the years, but the structure remains very much as it did when it was erected in 1946. I will propose adapting to the defunct space, a forward thinking school based on hands-on, creative learning. This school will challenge accepted pedagogies and serve as an exapmple of future learning. I have always looked as adaptive reuse interior design as a parasitic form of designing. The new program is almost never intendeed for the original space as it was designed and therfore should show its uniqueness in contast to the site. In this thesis, I will explore how the program will influence the design process, thus creating the most appropriate design to facilitate a futuristic learning environment in a obsolete manufacturing plant.

Embora várias espécies do território brasileiro tenham sido investigadas nos últimos anos quanto a aspectos de história natural, o conhecimento acerca do parasitismo ainda é escasso concentrado em alguns ecossistemas, como Restingas e Floresta Atlântica. No presente trabalho, a presença de helmintos foi avaliada em diversas espécies de lagartos de três ecossistemas do Brasil Central: Cerrado, Pantanal e Amazônia. Os espécimes utilizados foram provenientes de cinco coleções científicas: Coleção de Vertebrados da Universidade Federal de Mato Grosso, Coleção de Herpetologia da Universidade Federal de Góias, Coleção Zoológica de Referência do Campus de Corumbá, Coleção Zoológica de Referência da Universidade Federal de Mato Grosso do Sul e Coleção Herpetológica Arlindo de Figueiredo Bedá. Após a necropsia, os helmintos foram identificados e depositados na Coleção Helmintológica do Instituto de Biociências da UNESP de Botucatu. Foram calculados os seguintes parâmetros de infecção: Prevalência (porcentagem de indivíduos infectados em cada espécie hospedeira) e a Intensidade média da infecção (número médio de parasitos nos lagartos infectados). 0 índice de diversidade de Brillouin foi calculado para cada espécie hospedeira. Relação entre o comprimento rostro-cloacal e número total de parasitas e diversidade de helmintos foi testada através de correlação de Pearson. Análises de agrupamento (UPGMA) foram realizadas para avaliar a similaridade (índice de Sorensen) entre as áreas dentro dos biomas utilizando apenas os dados qualitativos. Um total de 955 indivíduos pertencentes a 66 espécies de lagartos foram necropsiados, dos quais 45,8% estavam parasitados. A prevalência por ecossistema foi de 58% de animais parasitados na amostra do Cerrado... / Brazilian diversity of lizards includes 236 species, although many aspects of lizard biology, including parasitism are poorly studied. These few studies are concentrated mostly on animals from Atlantic forest and Restinga. Herein we investigate the helminth parasites of lizards in three biomes of central Brazil Cerrado (savanna-like vegetation), Pantanal (floodplain) and Amazonia (rain forest). We look for helminths within the body cavity, esophagus, stomach, lungs, small and large intestines of each specimen under a stereomicroscope. Nematodes were cleared in phenol; Cestoda, Trematoda and Acanthocephala were stained in Carmim, dehydrated graded alcohols, cleared in Creosote and after identification, these helminths were deposited in the Coleção Helmintológica do Instituto de Biociências da Unesp de Botucatu, Brazil. A total of 955 individuals from 66 species of lizards representing 9 families were assessed, wherein 45.8% displayed helminthes. In the Cerrado the prevalence was 58% (a total of 436 specimens from 39 species), whereas in the Pantanal the overall prevalence was 53.9% (221 individuals from 27 species) and 54.2% (295 specimens from 31 species) was the prevalence in the Amazon. A total of 156,435 helminths from 62 species, including 8 trematodes, 2 acanthocephalans, 5 cestodes and 47 nematodes were found. Tropiduridae, Teiidae an Scincidae were the most parasitized lizard families in all biomes, while Gymnophthalmidae were lesser infected. Lizards with larger body sizes tend to have richer diversity and abundance of helminths. Cluster analysis revealed higher similarities between different populations of the same lizard species than phylogenetically closest sympatric species

Helminth ichthyo-parasitic fauna of a South African Sub-Tropical LakeMatla, Matsoele Moses January 2012 (has links)
Thesis (Ph.D. (Zoology)) --University of Limpopo, 2012 / The diversity of the helminth parasites of fishes in a clear-water, subtropical Lake
Tzaneen, in South Africa was investigated. Of the 527 fish specimens sampled
approximately 9000 parasites were collected. There are 38 different parasite species
discussed comprising 27 Monogenea, 3 Digenea, 4 Cestoda, 3 Nematoda and 1
Acanthocephala. Four new monogenean species are described and these are
Dactylogyrus spp. 1 to 4. Three monogenean species are introduced as first records
in Africa and these are Actinocleidus fusiformis (Mueller, 1934), Haplocleidus
furcatus Mueller, 1937 and Acolpenteron ureteroecetes Fischthal & Allison, 1940.
Fourteen monogenean and one acanthocephalan species are discussed as first
geographical records for South Africa and these are Gyrodactylus rysavyi Ergens,
1973, Dactylogyrus brevicirrus Paperna, 1973, Dactylogyrus cyclocirrus Paperna,
1973, Dogielius dublicornis Paperna, 1973, Dogielius sp., Schilbetrema quadricornis
Paperna & Thurston, 1968, Quadriacanthus aegypticus El Naggar & Serag, 1986,
Quadriacanthus clariadis Paperna, 1961, Scutogyrus gravivaginus (Paperna &
Thurston, 1969), Cichlidogyrus quaestio Douëllou, 1993, Cichlidogyrus halli Price &
Kirk, 1967, Cichlidogyrus sclerosus Paperna & Thurston, 1969, Cichlidogyrus
dossoui Douëllou, 1993, Cichlidogyrus tilapiae Paperna, 1960 and Acanthosentis
tilapiae Baylis, 1948. Seven species are discussed as first records for their hosts and
these are Cichlidogyrus dossoui, Cichlidogyrus halli and Acanthosentis tilapiae on
Oreochromis mossambicus; Dactylogyrus sp. 1 on Barbus radiatus and Barbus
trimaculatus; Dactylogyrus sp. 2 on Barbus unitaeniatus; Dactylogyrus sp. 3 and
Dactylogyrus sp. 4 on Labeo molybdinus. Gyrodactylus rysavyi is the only species
with a first site (gills) record. The other monogenean species discussed are
Macrogyrodactylus clarii Gussev, 1961, Macrogyrodactylus karibae (Douellou and
Chishawa, 1995), Dactylogyrus afrolongicornis afrolongicornis Paperna, 1973,
Dactylogyrus allolongionchus Paperna, 1973, Dactylogyrus spinicirrus (Paperna &
Thurston, 1968) and Cichlidogyrus philander (Douëllou, 1993). The digeneans
discussed are Glossidium pedatum Looss, 1899 and the larvae of Diplostomum van
Nordmann, 1832 and Clinostomum Leidy, 1856. The Cestodes discussed are
Proteocephalus glanduligerus (Janicki, 1928) Fuhrmann, 1933, Polyonchobothrium
clarias Woodland, 1925 and the larvae of Ligula intestinalis Goeze, 1782 and family Gryporhynchidae. The nematodes discussed are Procamallanus laevionchus (Wedl,
1861), Paracamallanus cyathopharynx Baylis, 1923 and larvae of Contracaecum
Railliet and Henry, 1912. Monogenea were commonly found on the gills but less on
the skin and in the urinary bladder. Digenea were found mainly in the eyes, brain and
visceral cavity, with only one species (Glossidium pedatum) present in the intestines
of Clarias gariepinus. Cestoda and Nematoda were found in the intestine and body
cavity. Only one species of Acanthocephala (Acanthosentis tilapiae) was found in the
intestines of Oreochromis mossambicus. No definite seasonal variations of infection
and parasite affinities towards the sexes and the sizes of the hosts could be
determined. The lake is oligotrophic with the water quality having no influence on the
parasite diversity and species richness. / the University of Limpopo Research Office, and the National Research Foundation

Compensation of Parasitic Inductance for Capacitors Applied to Common- and Differential-Mode Noise SuppressionYeh, Cheng-Yen 26 July 2007 (has links)
The suitable frequency range of electromagnetic interference (EMI) filters is always limited by the parasitic inductances and capacitances of components. The main object in this research is to develop design rules for lowering parasitic effects due to parasitic inductance of capacitor by using three coupled inductors. In this thesis, the properties and equivalent circuit of three coupled inductors are discussed first. It is found that two negative series inductances can be simultaneously obtained at two ports when the parameters of three coupled inductors are appropriately selected. These two negative inductances can be used to lower parasitic effect of capacitors. In other words, the EMI filter performance can be effectively improved by using this technology. Furthermore, method to completely reduce parasitic inductances is derived. The common mode insertion loss of this design is able to achieve at the rate of -60 dB/decade at high-frequency. For differential mode the insertion loss is even higher to the rate of -100 dB/decade.
