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…

Olsen 2018Settore ICAR/21 - UrbanisticaSettore M-GGR/01 - GeografiaSacco and Blessi 2009). In the current (post-) pandemic context and through the lens of a southern European perspective the purpose of this article is to critically reflect about the role of culture as possible vehicle of urban and community regeneration. In particular we will focus on the activities of the no profit organization «Laboratorio Zen Insieme» in ZEN2 one of the last large popular and peripheral neighborhoods built in Palermo at the end of 80s in order to explore and understand how cultural practices work as agent of urban and social transformation capable of addressing emerging issues especially in the pandemic scenario we are experiencing. Thecasestudy has been conducted through analysis of documents participative observations (Honer and Hitzler 2015) and qualitative in-depth interviews with key actors involved in the conception organization and management of the activities carried out by Laboratorio Zen Insieme with representatives of local institutions and non-formal conversations with participants of the workshops heldin the neighborhood. The experience we narrate finds that cultural practices have re-conceptualized their design and functions as strategies of urban and community regeneration and at the same time have contributed to answer to emergent issues in developing proximity and local based strategies facing up to problems inherent civil rights educationalpoverty socio-spatial justice and have changed the image and identity of urban places they inhabit.In this sense the research provides a framework for development of strategies and legitimization for cultural practices and a point of discussionabouttheirrolein urban development.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 groups a response to the new social and individual needs has been offered by cultural institutions that play a role of territorial agency often independently or in the absence of political institutions. Far from the idea of entertainment and divertissement it is in fact increasingly clear how the practices of cultural innovation experimenting with various forms of action and participation can in some cases play a fundamental role in the processes of social cohesion and community building representing an antidote to the worsening of the phenomena of marginalization and socio-spatial inequalities within cities and territories (Colantonio and Dixon 2011

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.

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…

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
