Taxas de substituições das Annonaceas: uma perspectiva do modelo códon
2014
The Annonaceae includes cultivated species of economic interest and represents an important source of information for better understanding the evolution of tropical rainforests. In phylogenetic analyses of DNA sequence data that are used to address evolutionary questions, it is imperative to use appropriate statistical models. Annonaceae are cases in point: Two sister clades, the subfamilies Annonoideae and Malmeoideae, contain the majority of Annonaceae species diversity. The Annonoideae generally show a greater degree of sequence divergence compared to the Malmeoideae, resulting in stark differences in branch lengths in phylogenetic trees. Uncertainty in how to interpret and analyse these…
Attraction of egg-killing parasitoids toward induced plant volatiles in a multi-herbivore context
2015
In response to insect herbivory, plants emit volatile organic compounds which may act as indirect plant defenses by attracting natural enemies of the attacking herbivore. In nature, plants are often attacked by multiple herbivores, but the majority of studies which have investigated indirect plant defenses to date have focused on the recruitment of different parasitoid species in a single-herbivore context. Here, we report our investigation on the attraction of egg parasitoids of lepidopteran hosts (Trichogramma brassicae and T. evanescens) toward plant volatiles induced by different insect herbivores in olfactometer bioassays. We used a system consisting of a native crucifer, Brassica nigr…
Cultural institutions as agents of urban and community regeneration in the (post-)pandemic city. The case of the «Laboratorio Zen Insieme» in Palermo
2022
Although all cities in the world have been affected by the COVID-19 pandemic, its impacts on the territories, yet to be understood, are unevenly distributed, revealing extremely varied imbalances depending on the places. However, it is clear that the virus and its variants have aggravated pre-existing socio-spatial inequalities, creating new ones and bringing attention back to those implications between space, planning, public health and citizenship that are at the origins of contemporary urbanism. In a reference framework in which the crisis is globalized but unequal and in the absence of a welfare system capable of responding to the urgencies of the most marginalized social contexts and g…
Mikrotik virtuālās laboratorijas ReSeLa vidē
2016
Strauji attīstoties virtualizācijas un mākoņskaitļošanas tehnoloģijām, tās tiek izmantotas ar vien plašākiem mērķiem. Virtualizācijas izmantošana virtuālo sistēmu veidošanā ir tikai viens no tās daudziem pielietojumiem. Darba mērķis ir, datortīklu apguves mācību procesā izmantojamu, virtuālo laboratoriju izveide uz ReSeLa platformas. Darba gaitā ir iepazīta MikroTik izveidotā maršrutētāju operētājsistēma un apgūta laboratoriju veidošanai izmantotā OpenStack sistēma. Darba laikā tika izveidotas strādājošas laboratorijas ar speciāli tām izveidotu testēšanas sistēmu, to pārbaudei un vērtēšanai.
Guía multimedia de operaciones básicas en análisis químico, farmacéutico y medioambiental
2008
En el presente proyecto se ha desarrollado una guía multimedia en formato electrónico como recurso de apoyo para la enseñanza y aprendizaje de las técnicas básicas del laboratorio analítico. La guía contiene ocho apartados donde los estudiantes pueden encontrar fácilmente información sobre las características de los reactivos químicos, descripción del material de laboratorio de uso frecuente, cómo se debe manejar y limpiar dicho material, instrucciones para no cometer errores en la operación de pesada de un sólido, como preparar de forma correcta una disolución, como llevar a cabo una valoración y las distintas etapas necesarias para calibrar un instrumento de medida, desde la preparación d…
Fluorescence explorer (FLEX): An optimised payload to map vegetation photosynthesis from space
2006
The FLuorescence EXplorer (FLEX) mission proposes to launch a satellite for the global monitoring of steady-state chlorophyll fluorescence in terrestrial vegetation. Fluorescence is a sensitive probe of photosynthetic function in both healthy and physiologically perturbed vegetation, and a powerful non-invasive tool to track the status, resilience, and recovery of photochemical processes and moreover provides important information on overall photosynthetic performance with implications for related carbon sequestration. The early responsiveness of fluorescence to atmospheric, soil and plant water balance, as well as to atmospheric chemistry and human intervention in land usage makes it an ob…

2022
Este documento ha sido revisado por el Servicio de política Linguística. Su labor ha sido muy importante para la correción del documento. Este documento contiene el cuadernillo de prácticas que utilizan los alumnos de Integración Bioquímica y Biología Molecular, asignatura de segundo año del grado de Medicina. El documento describe las diferentes sesiones de prácticas que se realizan en el laboratorio. Para cada práctica, se incluye una pequeña base teórica, así como el protocolo de cada sesión de laboratorio. Además, en algunos casos se incluyen preguntas relacionadas con las prácticas, para ser resueltas por el alumno. This document contains the lab book used by the Integration of Biochem…

An application of Matlab c on Dimensional Nonlinear Programming
2014
[EN] Nonlinear Programming (NLP) is a widely applicable tool in modeling real life problems applied to business, economics and engineering. Is to maximize or minimize a scalar field whose domain is given as a set of constraints given by equalities and/or inequalities not necessarily linear. In this paper we present a virtual laboratory to study the PNL graphically and numerically in the case of two variables
