Frecuencia del fenómeno de prozona en la detección rápida de reaginas plasmáticas (RPR) en pacientes coinfectados con VIH y sífilis. Hospital Nacional Dos de Mayo. diciembre 2014 – marzo 2015Velásquez Huamaní, Pedro Jean Piere January 2015 (has links)
Objetivos: Determinar la frecuencia del Fenómeno de Prozona en la prueba de detección rápida de reaginas plasmáticas (RPR) en individuos con coinfección por VIH y sífilis. Así mismo determinar la seroprevalencia de sífilis en los pacientes con VIH/SIDA atendidos en el Hospital Nacional Dos de Mayo mediante la Estrategia Sanitaria Nacional Prevención y Control de las ITS, VIH y SIDA (ESNITSS).
Métodos: Se estudiaron un total de 567 muestras de suero de pacientes con VIH/SIDA atendidos en la ESNITSS del Hospital Nacional Dos de Mayo, a todos se le realizó la prueba cualitativa de RPR, así como la cuantitativa hasta la dilución 1:32 con la finalidad de buscar fenómeno de prozona, para la confirmación serológica de la infección por sífilis, los sueros que resultaron reactivos fueron analizados con la prueba de hemaglutinación pasiva para la detección de anticuerpos específicos de T. pallidum (TPHA).
Resultados: Se realizó la búsqueda de fenómeno de prozona en toda muestra no reactiva en la prueba cualitativa del RPR no encontrándose caso alguno (0.0%). De las 567 muestras analizadas se encontraron 114 muestras reactivas en el RPR, de estas 108 resultaron positivas en el TPHA y 6 generaron resultados indeterminados en la misma prueba, la seroprevalencia determinada de sífilis en pacientes VIH positivos atendidos en la ESNITSS del Hospital Nacional Dos de Mayo fue de 20.1%.
Conclusiones: No se halló fenómeno de prozona en la población estudiada. La seroprevalencia de sífilis es alta y sería sugestivo de la falta de medidas de protección durante las relaciones sexuales. / --- Objectives: To determine prozone phenomenon frecuencies by RPR test in individuals with HIV and syphilis co-infection. Also, determine the frequency of HIV/syphilis coinfection in patients treated at Health Strategy for Control of STI and HIV/AIDS (ESNITSS) of the National Hospital Dos de Mayo.
Methods: A total of 567 serum samples from HIV positive patients attended at Hospital Nacional Dos de Mayo by ESNITSS program were evaluated. All samples underwent qualitative and quantitative RPR testing up to1:32 dilution in order to assess the presence of prozone phenomenon, all positive samples were confirmed for serological confirmation of syphilis infection using TPHA.
Results: There were not prozone phenomenon in all samples assessed. Of 567 samples analyzed, 114 samples were reactive for RPR, from these 108 were positive at TPHA and 6 resulted indeterminate. Syphilis seroprevalence in HIV-positive patients treated by ESNITSS of the Hospital Nacional Dos de Mayo was 20.1 %.
Conclusions: We did not found any case of prozone phenomenon in evaluated samples. The seroprevalence of syphilis in HIV positive patients treated at the Hospital Nacional Dos de Mayo by the SNITSS program is significantly high and this could indicate that a high percentage of HIV-positive patients do not take prevention measures during intercourse.

Optimal Design of a Planar 3-RPR Haptic Interface Based on ManipulabilityHarris, Wesley Kay 17 March 2010 (has links) (PDF)
A haptic interface is a robotic force feedback device that provides a sense of touch to users of virtual reality simulations. This thesis presents a general method for the design optimization of parallel planar haptic devices based on maximizing the manipulability of the interface over its workspace. Manipulability is selected as the key design objective to ensure avoidance of singular configurations within the workspace and to maximize the interface's ability to generate feedback forces and torques in each direction in each handle location and orientation. The optimization approach developed in this thesis results in a set of candidate designs that are found by stepping the design parameters through the range of possible values, and testing the manipulability and other measures (including workspace area and space) at each location and orientation of the interface handle. To find the optimal design, a multi-objective approach is taken to generate a set of Pareto optimal designs. A smart Pareto filter is employed to yield a smaller set of designs representative of the full Pareto frontier. The most desirable design is chosen from this reduced set. The result is a general optimization method applicable to parallel haptic interfaces. The method is demonstrated on the design of a 3-RPR parallel planar interface.

Agricultural waste and wood waste for pyrolysis and biochar : An assessment for Rwanda / Jordbruks- och träavfall för produktion av biokol : En utvärdering för RwandaEliasson, Jenny, Carlsson, Viktor January 2020 (has links)
A high priority in order to combat climate change is disposal of waste. In low-income countries, a large portion of biomass residues generated in the forestry, agricultural and industrial sectors could be usable, instead of being seen as waste. For instance, it could be converted into biochar, which is proven to have many environmental benefits. In Rwanda, the agricultural sector employs 80% of the population and accounts for 35% of GDP. This sector, together with later refinement of crops and forestry production, cause large amounts of residue that many times is considered as waste. In this report, a literature study was conducted to evaluate possible biochar production from agricultural and wood wastes in Rwanda. Characteristics that determine if a biomass could be suitable for a biochar production were identified as C, H, O, N, S, hemicellulose, cellulose, lignin, ash and moisture content, residue-to-product ratio, and low heating value. These characteristics were assessed for the chosen Rwandan agricultural and wood wastes, by compiling values from published reports. The result shows that there are large volumes of residues that have potential for biochar production instead of being seen as waste in Rwanda. Biochar production from these wastes could enable environmental benefits for Rwanda, although further investigation of each single biomass could be needed in order to see if it is practically, technically and financially possible to do in reality. / För att bekämpa klimatförändringen är avfallshantering en hög prioritet. I låginkomstländer kan en stor andel av biomassarester som genereras i skogsbruk, jordbruks- och industrisektorer vara användbara, istället för att ses som avfall. Till exempel skulle det kunna omvandlas till biokol, som har visats sig ha många miljömässiga fördelar. I Rwanda arbetar 80% av befolkningen inom jordbrukssektorn och den står för 35% av BNP. Denna sektor, tillsammans med förädling av grödor och skogsbruksproduktion, orsakar stora mängder rester som många gånger betraktas som avfall. I denna rapport genomfördes en litteraturstudie för att utvärdera möjlig produktion av biokol från jordbruks- och träavfall i Rwanda. Egenskaper som avgör om en biomassa kan vara lämplig för en biokolsproduktion identifierades som C-, H-, O-, N-, S-, hemicellulosa-, cellulosa-, lignin-, ask- och fukthalt, samt andel avfall som uppstår i förhållande till färdig produkt och värmevärde. Dessa egenskaper utvärderades för det valda jordbruks- och träavfallet genom att sammanställa värden från publicerade rapporter. Resultatet visar att det finns stora volymer rester som har potential för biokolsproduktion istället för att ses som avfall i Rwanda. En biokolsproduktion från dessa avfall skulle kunna ge miljömässiga fördelar för Rwanda, även om ytterligare undersökning av varje enskild biomassa skulle behövas för att se om det är praktiskt, tekniskt och ekonomiskt möjligt att genomföra i verkligheten.
