La cuenca del río Sipchoc, área de estudio del presente trabajo, está ubicada políticamente en los distritos de Aija y Recuay, provincia de Aija y Recuay, respectivamente, departamento de Ancash; cubre una extensión total de 8.79 Km2 . Dentro de esta cuenca se encuentran los pasivos resultantes de los procesos de producción en planta pertenecientes a la Cía. Minera Huancapetí, la cual produce concentrados de Ag – Pb – Zn. Las operaciones mineras generan una serie de impactos al medio ambiente, estos impactos son percibidos y se evidencian en un determinado espacio geográfico, que es el que se considera como el área de influencia ambiental. En base a lo anteriormente descrito, a los estudios que ha realizado la Compañía Minera Huancapetí S.A.C. y a la visita de campo de los especialistas de la consultora Green Consult S.A.C. en la zona donde se ubican sus pasivos ambienta...

En el primer cuatrimestre del año 2019, el gobierno de los Estados Unidos vetó a la marca Huawei de realizar operaciones comerciales en su territorio, debido que se le acusaba de conspirar con el gobierno chino sustrayendo información mediante sus equipos de tecnología. En consecuencia, Google decide finalizar acuerdos comerciales con dicha marca negando el uso de sus servicios como Google Play Store, Google Maps, entre otros. Esta medida representó una caída global en las ventas de los equipos de telecomunicaciones fabricados por la marca china, puesto que a los usuarios se les dificultaba la descarga de las aplicaciones más populares y sus actualizaciones. Ante este impacto negativo, Huawei tuvo que desarrollar “AppGallery”, con el fin de que sus consumidores puedan obtener alternativas similares a Google. Inicialmente, la tienda de aplicaciones de Huawei era muy limitada y ...

Introduction: Good Manufacturing Practices (GMP) are practices and procedures, their application is mandatory for establishments that produce, handle and sell food. Compliance with them avoids Foodborne Diseases (ETAS) guaranteeing health. The sale of food on public roads is a traditional practice, it represents a risk when GMPs are not applied. The objectives were to evaluate knowledge about GMP, investigate the application, and analyze the relationship between knowledge and the application of GMP. Methods: descriptive-correlational, cross-sectional study. The sample consisted of 20 individuals in charge of the 20 stalls at the Simoca Fair, with prior informed consent. The information was collected through a previous pilot test survey and a checklist in 2018. Results: People between 20 and 29 years of age, with complete primary and secondary education, predominated. Regarding the degree...

La presencia de artefactos en la obtención de la imagen de PET/CT es un hecho patente y presente en esta tecnología a nivel mundial. Los artefactos que afectan la sensibilidad y resolución pueden tener distintos orígenes, desde aquellos intrínsecos a la tecnología, como aquellos derivados del manejo del paciente en el momento de la adquisición de la imagen PET/CT. Los protocolos de apnea, han mostrado disminuir los artefactos relativos al movimiento respiratorio, y es posible que el incremento de la velocidad de adquisición, elimine los artefactos derivados del movimiento voluntario. Objetivo: Identificar el tipo y frecuencia de artefactos en estudios de PET-CT con 18F-FDG en pacientes oncológicos. Material y métodos: Se incluyó una muestra de los estudios adquiridos entre abril del 2014 y agosto del 2016, y los estudios fueron leídos por 2 tecnólogos médicos en radiología...

The study aimed to detect the presence of endoparasites in faecal samples of Trachemys. scripta elegans from private households in the Maule Region, Chile. The sampling was conducted to determine the prevalence of gastrointestinal parasites in 35 individuals (22 females and 13 males), using the Teuscher coproparasitic technique. Only one sample of a female turtle was positive (2.85%), corresponding to an undetermined species of coccidia.

The aim of this study was to determine the presence of ecto- and endoparasites in a canine population located in a mountainous rural sector of the Valparaíso region of Chile. Thirty canines were subjected to clinical inspection to collect ectoparasites and faeces of the rectum. Faecal samples were analysed using the Burrow’s coproparasitic technique and the SNAP® Giardia Test (IDEXX). Results showed that 73% of canines had endoparasites by the coproparasitic technique. The helminths Toxocara canis (40%), Strongyloides stercoralis (17%), Dipylidium caninum (17%), Uncinaria stenocephala (13%), Ancylostoma caninum (7%) Trichuris vulpis (3%), and the protozoa Isospora sp (13%), Sarcocystis sp (3%), Entamoeba coli (3%) and Blastocystis sp (3%). The prevalence of Giardia sp was 17%, but it was 27% by the SNAP® Giardia (p=0.0004). Ticks were found in 25 canines (83%), identifying the speci...
