Technology makes many of the tasks that were previously difficult to perform, nowadays can be solved, one of them is to be able to carry out studies on large tracts of land and at the same time be able to have a level of detail of them, through the study of the satellite images provided by the Earth observation satellites, these images are composed of a series of spectral bands that will depend on the type of satellite mission that was conceived and the optical instrument that is found as a payload, these images are represented by multidimensional arrays and large size, so computational high computation equipment is required to process the images, added to this requires specialized software that allows the visual interpretation of satellite images. To be able to work with satellite images you have many configurations, normally you work with the configuration of separate bands that consis...

A retrospective analysis of parasitological test results in fecal samples was done.Samples were analyzed at the Parasitology Laboratory, Faculty of Veterinary Medicineand Animal Science, Universidad Peruana Cayetano Heredia between February 2008and March 2012. Out of 476 samples, 119 (25.0%) were positive to at least one parasitespecies. Among positive samples, 71.5, 20.3 and 8.1% corresponded to protozoa,nematodes and cestodes respectively where the most frequent species were Giardiacanis (37/119) and Isospora spp (37/119).

Se analizaron retrospectivamente los resultados de exámenes parasitológicos demuestras fecales de caninos en el Laboratorio de Parasitología de la Facultad de Veterinaria y Zootecnia de la Universidad Peruana Cayetano Heredia, Lima, entre febrero de 2008 y marzo de 2012. De un total de 476 muestras, 119 (25.0%) resultaron positivas para al menos un tipo de parásito. De las muestras positivas, el 71.5, 20.3 y 8.1% correspondieron a protozoos, nematodos y cestodos, respectivamente, siendo las especies de mayor frecuencia Giardia canis (37/119) e Isospora spp (37/119).

In the new times we are living, the use of technology is causing many of the customs are changing, one of them is the development of children, in previous years children used to play with their friends in the parks, technology It has caused many of them to perform recreation activities based on the use of video games, these games have caused children to develop certain skills and also change their behavior when they perform certain activities, in this work a comparison between the levels of concentration and meditation levels when children carry out activities related to the realization of academic activities related to the accomplishment of the school tasks that they must perform, with the levels of concentration and meditation when the child is doing activities related to video games, methodology that was used to evaluate the levels The concentration and meditation is based on the use ...

When we want to work with signals produced by the human body, we face different challenges that we must address, from the sensor to be used, through the conditioning of the signal for later registration and analysis, these stages are important to have a Good record of the clean interference signal that are foreign to the signal. One of the challenges you have when working with the electromyography signal, is to be able to understand the behavior of the muscles accompanied by the biophysics of the movement that is performed, for your better understanding and analysis the monitoring of several muscles at the same time is required, what originates a multichannel record, this condition is a complex requirement at the time of being able to design a team that can perform this multi record, being able to record these signals is vital for a subsequent analysis and understanding of muscle activit...

The thermal comfort of beef cattle in intensive finishing was assessed through the availability of shade and living space, in conditions of the very hot semi-dry climate of the northwestern coastal region of Mexico during autumn and winter and housed in three types of pens. The design of the pens varied according to the infrastructure available in the livestock production unit (pen area and shade per animal). The observation period was six weeks per season. The daily ambient temperature and relative humidity were measured, and the Temperature and Humidity Index (ITH) was calculated. The area of each pen, the shade area, and the number of cattle per pen were measured to calculate the living space and the shade available at the beginning and at the end of the fattening period. In autumn, the cattle were in a state of Danger to Emergency Thermal (ITH ≥84 units) and in the winter in a stat...

Background: Trichosporon fungaemia (TF) episodes have increased in recent years and mortality rates remain high despite the advances in the management of sepsis. New concepts about its clinical course, treatment and microbiology need to be investigated for the better management of this infection. Objectives: To describe the aetiology, natural history, clinical management and prognostic factors of TF. Methods: TF episodes documented between 2005 and 2018 in 23 South American centres were retrospectively investigated by using a standard clinical form. Molecular identification, antifungal susceptibility testing and biofilm production were also performed. Results: Eighty-eight TF episodes were studied. Patients had several underlying conditions, including haematological diseases (47.7%), post-operative status (34%), solid organ transplants (n = 7, 7.9%), among others. Seventy-three (82.9%) p...
