The report deals with the material on freshwater crabs, collected by the Austrian-Ceylonese hydrobiological mission 1970 from the running waters of the mountains in south-west Ceylon. The locality records for Paratelphusa (Oziotelphusa) senex (Fabricius 1798) Paratelphusa (Ceylontelphusa) sorror (Zehntner 1894) and Paratelphusa (Ceylontelphusa) rugosa (Kingsley 1880), are described.

A total of 378 specimens from 25 collecting localities belonging to 31 different species of fish collected mainly from the rivers of the hilly and mountain regions of the south-western and southern Ceylon have been identified and recorded. Ecological data and water analyses of these collecting localities are given.

The Trichoptera collected in Sri Lanka by the Austrian Indo-Pacific expedition in autumn and winter 1970 (larvae and adults) are evaluated systematically and ecologically. The following new species are described: Pseudoneureclipsis starmuehlneri, P. maliboda (Polycentropodidae), Oecetis belihuloya (Leptoceridae), and Helcopsyche sri lanka (Helicopsychidae). Helicopsyche ceylanica Brauer 1866 is re-described. Several types of larvae and cases of Hydropsyche (Hydropsychidae), Ceylanopsyche (Sericostomatidae) and Helicopsyche are described or at least roughly characterised. According to the larval characters the genus Ceylanopsyche seems to belong to Sericostomatidae s. str.

In the present study the specimens collected by the Austrian-Ceylones hydrobiological mission 1970 are described. The freshwater gastropods in this study were collected from 100 different localities, mostly running waters, but some were also collected from stagnant waters like pools, irrigated paddy fields, swamps and water reservoirs (tanks). Listed from these localities are 31 species (and subspecies) 28 species are Streptoneura (=Prosobranchia), 3 species are Euthyneura-Pulmonata Basommatophora.

Pt. 19. Aquatic and semiaquatic Hemiptera of Sri Lanka from the Austrian Indo-Pacific expedition, 1970-71

This report concerns the aquatic and semiaquatic Hemiptera collected in Sri Lanka by Prof. Starmühlner and Prof. Costa during November and December 1970. A surprising number of new species have been found in the Starmühlner-Costa material, even in groups for which comprehensive revisions exist. Seven new species are described here.

Entre sus actividades, realizó numerosas ilustraciones de Trabajos científicos, tesis doctorales, ilustraciones de trabajos inéditos, comunicaciones a congresos, simposios reuniones científicas, libros algunos de ellos sobre la enseñanza de la ilustración científica. Exposiciones como organizadora e integrante en el marco de congresos de biología museos y galerías. Realizo maquetas y dioramas para diferentes salas del Museo de Ciencias Naturales de La Plata, y sellos postales para el Correo Argentino. Desarrolló una labor artística como miniaturista en biología. En 1985 crea el curso de Introducción a la Ilustración Científica, pasantías de formación y actividades de extensión sobre Ilustración Científica. Este archivo, además de revelar las dotes de ilustradora científica y plásticas de la Sra. Estivariz, muestra que el Museo de La Plata es un generador, no sólo del conocimiento, sino también del virtuosismo de sus integrantes.

Anticancer and antiangiogenic activity of surfactant-free nanoparticles based on self-assembled polymeric derivatives of vitamin e: Structure-activity relationship

α-Tocopheryl succinate (α-TOS) is a well-known mitochondrially targeted anticancer compound, however, it is highly hydrophobic and toxic. In order to improve its activity and reduce its toxicity, new surfactant-free biologically active nanoparticles (NP) were synthesized. A methacrylic derivative of α-TOS (MTOS) was prepared and incorporated in amphiphilic pseudoblock copolymers when copolymerized with N-vinylpyrrolidone (VP) by free radical polymerization (poly(VP-co-MTOS)). The selected poly(VP-co-MTOS) copolymers formed surfactant-free NP by nanoprecipitation with sizes between 96 and 220 nm and narrow size distribution, and the in vitro biological activity was tested. In order to understand the structure-activity relationship three other methacrylic monomers were synthesized and characterized: MVE did not have the succinate group, SPHY did not have the chromanol ring, and MPHY did not have both the succinate group and the chromanol ring.

“Fiction makes a better job of the truth”: dialogism, oppositional consciousness and re-membering in the novels of Helena María Viramontes

This thesis comprises close textual analyses of Chicana author Helena María Viramontes' two published novels, Under the Feet of Jesus (1995) and Their Dogs Came With Them (2007). These analyses fall under three broad frameworks: space, time and body. Chapter One engages with the first of these frameworks, space, and explores concepts of cognitive mapping and heteroptopias. Chapter Two, which looks at time, employs theories of intertextuality and the palimpsest, while Chapter Three looks at the interrrelationship between mythology and images of the body in the texts. This study emerges five years after the publication of Viramontes' last novel, Their Dogs Came With Them, but offers fresh insight into the contribution of the author to both the Chicano literary tradition and also the U.S. canon through her critique of hegemonic power structures that suppress not only the voices of lower class ethnic citizens but also of ethnic writers. In particular, her work chastises the paucity of attention given to ethnic women writers in the U.S. This thesis reaffirms Viramontes' position as one of the most important writers living and writing in the U.S. today. It corroborates her work as a contestation against ethnic and gender suppression, and applauds the craftsmanship of her narrative style that delicately but decisively exposes the socio-political wrongs that occur in ocntemporary U.S. society.

The increasing impact of human immunodeficiency virus infections, sexually transmitted diseases, and viral hepatitis in Durham County, North Carolina: a call for coordinated and integrated services.

BACKGROUND: Durham County, North Carolina, faces high rates of human immunodeficiency virus (HIV) infection (with or without progression to AIDS) and sexually transmitted diseases (STDs). We explored the use of health care services and the prevalence of coinfections, among HIV-infected residents, and we recorded community perspectives on HIV-related issues. METHODS: We evaluated data on diagnostic codes, outpatient visits, and hospitalizations for individuals with HIV infection, STDs, and/or hepatitis B or C who visited Duke University Hospital System (DUHS). Viral loads for HIV-infected patients receiving care were estimated for 2009. We conducted geospatial mapping to determine disease trends and used focus groups and key informant interviews to identify barriers and solutions to improving testing and care. RESULTS: We identified substantial increases in HIV/STDs in the southern regions of the county. During the 5-year period, 1,291 adults with HIV infection, 4,245 with STDs, and 2,182 with hepatitis B or C were evaluated at DUHS. Among HIV-infected persons, 13.9% and 21.8% were coinfected with an STD or hepatitis B or C, respectively. In 2009, 65.7% of HIV-infected persons receiving care had undetectable viral loads. Barriers to testing included stigma, fear, and denial of risk, while treatment barriers included costs, transportation, and low medical literacy. LIMITATIONS: Data for health care utilization and HIV load were available from different periods. Focus groups were conducted among a convenience sample, but they represented a diverse population. CONCLUSIONS: Durham County has experienced an increase in the number of HIV-infected persons in the county, and coinfections with STDs and hepatitis B or C are common. Multiple barriers to testing/treatment exist in the community. Coordinated care models are needed to improve access to HIV care and to reduce testing and treatment barriers.
