A LIGHTWEIGHT UAV-BASED LASER SCANNING SYSTEM FOR FOREST APPLICATION
Lightweight Unmanned Aerial Vehicles (UAVs) have become a cost effective alternative for studies which use aerial Remote Sensing with high temporal frequency requirements for small areas. Laser scanner devices are widely used for rapid tridimensional data acquisition, mainly as a complementary data source to photogrammetric surveying. Recent studies using laser scanner systems onboard UAVs for forestry inventory and mapping applications have presented encouraging results. This work describes the development and accuracy assessment of a low cost mapping platform composed by an Ibeo Lux scanner, a GNSS (Global Navigation Satellite System) antenna, an Inertial Navigation System Novatel Span-IGM-S1, integrating a GNSS receiver and an IMU (Inertial Measurement Unit), a Raspberry PI portable computer and an octopter UAV. The system was assessed in aerial mode using an UAV octopter developed by SensorMap Company. The resulting point density in a plot with trees concentration was also evaluated. The point density of this device is lower than conventional Airborne Laser Systems but the results showed that altimetric accuracy with this system is around 30 cm, which is acceptable for forest applications. The main advantages of this system are their low weight and low cost, which make it attractive for several applications
Quality and Shelf-Life Stability of Pork Meat Fillets Packaged in Multilayer Polylactide Films
[EN] In the present study, the effectiveness of a multilayer film of polylactide (PLA), fully bio-based and compostable, was ascertained to develop a novel sustainable packaging solution for the preservation of fresh pork meat. To this end, the multilayer PLA films were first characterized in terms of their thermal characteristics, structure, mechanical performance, permeance to water and aroma vapors and oxygen, and optical properties and, for the first time, compared with two commercial high-barrier multilayer packaging films. Thereafter, the multilayers were thermosealed to package fillets of fresh pork meat and the physicochemical changes, lipid oxidation levels, and microbiological counts were monitored in the food samples during storage under refrigeration conditions. Results showed that the meat fillets packaged in PLA developed a redder color and showed certain indications of dehydration and oxidation, being more noticeably after 11 days of storage, due to the higher water vapor and oxygen permeance values of the biopolymer multilayer. However, the pH changes and bacterial growth in the cold-stored fresh pork meat samples were minimal and very similar in the three tested multilayer films, successfully accomplishing the requirements of the food quality and safety standards at the end of storage.This research was funded by the Spanish Ministry of Science and Innovation (MICI), grant number PID2019-105207RB-I00.

Investigación Cualitativa en Ciencias Sociales
Esta pesquisa traz um olhar das estruturas e do poder que exerceram as enfermeiras, dentro das instituições hospitalares por manter a hegemonia, utilizando-‐se a teoria de pensamento estratégico conceitualizada como um pensamento sobre o poder, em particular sobre as formas do uso do poder (Testa, 1995Objetivo: descrever as circunstâncias que levaram às enfermeiras à gerência de hospitais públicos, e discutir as diferentes posições políticas dos integrantes da equipe de saúde no processo de gestão das diretoras-‐enfermeiras. Método: estudo de caso, com base na Teoria de Pensamento Estratégico. Para análise utilizou-‐se a matriz de categorias e explanação concorrente simples destes casos. Resultados: as categorias apreendidas foram função de direção na percepção das enfermeiras, atuações dos médicos diante do desenvolvimento dos fatos e da visão dos dirigentes. Estas verificaram que a base política é o fator essencial para o exercício da gerência e do sucesso que tiveram as enfermeiras durante a gestão hospitalar. Conclusão: deve-‐se valorizar o poder que têm pelo quantitativo de sua categoria, desenvolver alianças e coligações políticas com outros setores, uma vez que as enfermeiras em sua prática profissional detêm o controle do processo operativo
Asociación del sobrepeso y obesidad en estudiantes universitarios mexiquenses y la actividad física
La obesidad ha alcanzado proporciones epidémicas a nivel mundial, y cada año
mueren, como mínimo, 2,8 millones de personas a causa de la obesidad o
sobrepeso. Aunque anteriormente se consideraba un problema confinado a los
países de altos ingresos, en la actualidad la obesidad también es prevalente en los
países de ingresos bajos y medianos.
En los últimos 30 años la obesidad surgió como un importante problema de salud
pública a nivel mundial. La Organización Mundial de la Salud utilizó la denominación
"epidemia global" para describir este fenómeno

Birthdays are special events for everybody and for most of people it is an important date in their life, it is the day where they feel honoured and appreciated by their friends, family, acquaintances…
The main reason for creating an application dedicated to make from the Birthday event a fun game, is generated after bearing in mind how the tradition of giving presents to honour a birthday person is something important in many people\u27s lives.
Another aspect considered during the conception of this application is how fast the world is moving, and how sometimes it could be beneficial to have different options to make from an event something different and special.
Under this knowledge it is importantly understood that creating an app is a work that requires significant amounts of time and attention. Something that in a fast pace world like this can be considered a luxury.Nevertheless, the opportunity to offer something different to a specific target of users, who enjoy gaming options, is an interesting and worthwhile challenge to be taken
Percepção de um grupo de homens acerca da Diabetes Mellitus: contribuições para a enfermagem
Artículo que muestra el papel del hombre en relación con el binomio salud-enfermedad ha sido poco estudiado; en este sentido, la percepción puede ser un referente para su cuidado científico de enfermería.The aim was to understand how men in the State of Mexico perceive diabetes. An ethnographic study based on in-depth interviews with 15 men with diabetes who participate in an exercise program, in a municipality in Mexico. For a period of eleven months, the main researcher remained in contact with this community of men who belong to a support group. Content analysis was performed to group data into categories. The men expressed that in their daily lives the disease gave rise to different feelings, such as fear, anxiety, anger and sadness. These perceptions help nurses to understand the social and cultural world, comprised of beliefs, actions and interactions. The field of nursing is in need of new paradigms to provide an epistemic foundation for the care of these men living with diabetes.Sin patrcinado
