Comparação entre técnicas coproparasitológicas no diagnóstico de ovos de helmintos e oocistos de protozoários em cães.

In this study we evaluated the frequency of enteroparasites in pet dogs and their association with age, sex and breed, as well as the efficiency of the Willis-Mollay, Faust, Sedimentation and Direct exam methods. By these methods we processed 401 fecal samples. The samples were positive in the following percentages: Ancylostoma spp. (53.1%), Toxocara canis (20.7%), Cystoisospora ohioensis (15.7%), Trichuris vulpis (3.7%), Dipylidium caninum (2.5%) and Taenia spp. (1.0%). Toxocara canis (67.3%) and C. ohioensis (47.3%) showed higher positivity in the puppies. The Willis-Mollay technique was more efficient in the diagnosis of Ancylostoma spp. and T. canis eggs. The Direct method was the least efficient. It was found that the majority of the cases of D. caninum were diagnosed by the Sedimentation method (8=2.0%), while for T. vulpis Willis-Mollay (12=3.0%) and Sedimentation (13=3.2%) were more efficient. In view of these results, we can recommend the association of Willis-Mollay and Sedimentation methods for the diagnosis of gastrointestinal helminths. Due to the elevated occurrence of Ancylostoma spp. and T. canis, which are involved in zoonotic diseases, it becomes necessary to apply more efficient prophylaxis of canine intestinal parasitosis at the City of Araçatuba, state of São Paulo.

Diagnóstico do uso de técnicas de calagem e aubação dos assentamentos rurais do estado de São Paulo: estudo de caso

In the context of the project “Development and qualification of agriculturists in the use of techniques for correction of theground in agricultural assentament”, the identification of the use of agricultural techniques becomes necessary as an important tool for decision taking, mainly in regards to the public politics of Assistance Technique and Agricultural Extension (ATER). In such a way, the present study it had for objectiveto diagnosis the use of limeand fertilization techniques in these agricultural assentamentin order to identify possible public politics ATER. Of the total of boarded families, 79.89% had answered to the questionnaire elaborated for this diagnosis. The field research was carried throughapplication of questionnaire elaborated for this study and the analysis of the results divided in profile of the beneficiaries, knowledge of techniques of ground handling and agricultural use of the areas of the Projects of Assentamentfor the beneficiaries. It was concluded that even so the great majority of the beneficiaries agricultural area and farmers to be declared diligent of this information are not in coherence with the one of knowledge of the type of ground, therefore, this type of understanding of the landscape is primordial for the taking of decision with regard to the agricultural use of the ground, moreover, the access to the knowledge and use of the techniques of limeand fertilization comes diminishing in the agricultural assentamentunder validity of II National Plan of the Agrarian Reformation, what it enters in total discord with the premises of the same. It fits here to detach the importance of public politics ATERdirected these beneficiaries of the Agrarian Reformation, mainly with regard to the ground handling.

Nuevos desarrollos en la medida de descargas parciales y técnicas avanzadas de análisis para el diagnóstico del estado de los aislamientos en sistemas eléctricos de alta tensión

En esta tesis se desarrolla una investigación sobre las técnicas de medida de descargas parciales (DP) que se aplican en medidas on-line, en condiciones normales de operación de las instalaciones eléctricas de alta tensión (AT). También se realiza un estudio de técnicas avanzadas de procesado y análisis de las señales medidas, que permiten realizar diagnósticos precisos del estado de los aislamientos eléctricos de AT. Uno de los objetivos fundamentales de la tesis ha sido disponer de un procedimiento eficaz de medida y procesado de las señales de DP, para la realización de medidas on-line tanto de forma itinerante, como mediante monitorización temporal o permanente. La implementación del nuevo procedimiento de medida permite obtener resultados satisfactorios en la detección, identificación y localización de defectos de aislamiento. Se ha dedicado especial interés al desarrollo de un método de clasificación de señales, que permite separar pulsos de ruido y diferentes fuentes de DP, presentes de forma simultánea en las instalaciones de AT. El estudio de la clasificación de señales se ha completado con la aplicación de un método para la detección de manera asistida, de los diferentes grupos de pulsos de ruido y de DP. La aplicación de este método de detección de grupos de pulsos, facilita la labor de los técnicos especialistas a la hora de diagnosticar el estado de los elementos aislantes. Al efecto de verificar de forma práctica las aportaciones de la tesis, se han realizado medidas de DP tanto en laboratorio como en campo. Las medidas experimentales en laboratorio se han efectuado en el Laboratorio de Alta Tensión de la Escuela Técnica Superior de Ingeniería y Diseño Industrial (LAT-UPM), de la Universidad Politécnica de Madrid. Por otro lado, las medidas experimentales en campo se han llevado a cabo en instalaciones de AT propiedad de compañías de transporte y distribución de energía eléctrica. La realización de ensayos de DP en estas instalaciones ha sido posible, gracias a los proyectos de investigación llevados a cabo por el grupo de trabajo del LAT-UPM, con diferentes empresas del sector durante los diez últimos años. ABSTRACT This thesis develops techniques for measuring partial discharges (PD) that are applied in on-line measurements, under normal operating conditions of the high voltage (HV) electrical installations. In addition there are studied advanced techniques for the processing and analysis of the measured signals, that permit precise diagnostics of the state of HV electrical insulation systems. One of the fundamental objectives of the thesis is to make available an effective procedure for measuring and processing PD signals, for making on-line measurements, either in an itinerant way or in temporary or permanent monitoring. The implementation of the new measurement procedure yields satisfactory results in the detection, identification and localization of insulation defects. Special attention has been devoted to the development of a method for classifying signals, that separates noise pulses and various PD sources present simultaneously in the HV installations. The study of the classification of signals has been completed by the application of a method for detecting, in a user assisted manner, the different groups of noise pulses and of PD. The application of this method for detecting groups of pulses facilitates the work of the specialist technicians to diagnose the condition of the insulation elements. To demonstrate the practical value of the thesis, PD measurements were made in laboratory as well as in field installations. The experimental measurements in laboratory were made in the High Voltage Laboratory (LAT-UPM) of the High Technical School of Engineering and Industrial Design, of the Polytechnic University of Madrid. Field measurements were realized in the HV installations of companies providing electrical energy transport and distribution. The realization of PD tests in these facilities was possible thanks to the research projects carried out by the working group of the LAT-UPM during the last ten years, with different companies operating in the sector.

Um sistema inteligente de teleoftalmologia para o auxílio no diagnóstico de catarata

The increasing in world population, with higher proportion of elderly, leads to an increase in the number of individuals with vision loss and cataracts are one of the leading causes of blindness worldwide. Cataract is an eye disease that is the partial or total opacity of the crystalline lens (natural lens of the eye) or its capsule. It can be triggered by several factors such as trauma, age, diabetes mellitus, and medications, among others. It is known that the attendance by ophthalmologists in rural and poor areas in Brazil is less than needed and many patients with treatable diseases such as cataracts are undiagnosed and therefore untreated. In this context, this project presents the development of OPTICA, a system of teleophthalmology using smartphones for ophthalmic emergencies detection, providing a diagnostic aid for cataract using specialists systems and image processing techniques. The images are captured by a cellphone camera and along with a questionnaire filled with patient information are transmitted securely via the platform Mobile SANA to a online server that has an intelligent system available to assist in the diagnosis of cataract and provides ophthalmologists who analyze the information and write back the patient’s report. Thus, the OPTICA provides eye care to the poorest and least favored population, improving the screening of critically ill patients and increasing access to diagnosis and treatment.

Técnicas avanzadas de análisis financiero: aplicación al diagnóstico y pronóstico en oncología clínica

La curación de un proceso neoplásico no siempre es posible, por lo que durante las últimas décadas los estudios oncológicos realizados buscaban una mejor comprensión de la naturaleza del cáncer que permitiese obtener para los pacientes supervivencias cada vez mayores. Estos estudios se realizaban con el fin de conseguir técnicas quirúrgicas más depuradas, fármacos más eficaces y con menos efectos adversos, etc. El propósito de esta Tesis Doctoral es ofrecer un marco teórico, novedoso en el campo de la oncología molecular, que haga posible la identificación de genes diana. Se desea aportar una nueva propuesta basándose en los perfiles de expresión4 obtenidos en función de un nuevo parámetro que clasifique los tumores no por su histopatología, fundamento en el que se sustentan las principales clasificaciones tumorales como por ejemplo: Dukes5, Astler y Coller o TNM, sino por la variabilidad en la expresión de los genes. Para abordar esta cuestión, se utiliza uno de los parámetros empleados en la caracterización del riesgo bursátil: la beta de un activo financiero. Se traslada este concepto a la oncología molecular. La identificación de genes se realiza teniendo en cuenta los perfiles de expresión obtenidos en función de las betas de los genes...
