Pharmacokinetics of the cannabinoid receptor ligand [18 F]MK-9470 in the rat brain - Evaluation of models using microPET

2018

PURPOSE The positron emission tomography ligand [18 F]MK-9470 is an inverse agonist that binds reversibly and with high affinity to the cannabinoid type 1 receptor. Due to its slow brain kinetics, care is required in the definition of its dissociation rates from the receptor. The goal of this study was to investigate pharmacokinetic analysis methods using an arterial input function. METHODS Five Sprague-Dawley rats received injections of 13 to 25 MBq of [18 F]MK-9470 and were scanned over a period of 90 min. Arterial blood samples were collected throughout the scan. Data were analyzed using four different compartmental models: a reversible one-tissue model, reversible two tissue models with…

Two ways to handle dependent uncertainties in multi-criteria decision problems☆

2009

Abstract We consider multi-criteria group decision-making problems, where the decision makers (DMs) want to identify their most preferred alternative(s) based on uncertain or inaccurate criteria measurements. In many real-life problems the uncertainties may be dependent. In this paper, we focus on multicriteria decision-making (MCDM) problems where the criteria and their uncertainties are computed using a stochastic simulation model. The model is based on decision variables and stochastic parameters with given distributions. The simulation model determines for the criteria a joint probability distribution, which quantifies the uncertainties and their dependencies. We present and compare two…

RELIABILITY AND VALIDITY OF THE LATVIAN VERSION OF THE COMPUTERIZED EXECUTIVE FUNCTIONS TEST “EXAMINER” IN A STUDENTS SAMPLE: RESULTS OF THE PILOT ST…

2016

The aim of this pilot-study was to assess reliability and validity of the Latvian version of the computerized executive functions test EXAMINER (Executive Abilities: Measures and Instruments for Neurobehavioral Evaluation and Research) in a sample of high school students and university students. The adaptation procedure included translation of the instructions and technical configuration of the test’s computerized version. The Latvian version of the EXAMINER includes tasks that measure executive functions of inhibition, set shifting and working memory updating. Participants included two sub-groups: 22 (14 males, 8 female) students from high school and 39 students (11 males, 28 female) from …

EXPLORING THE EFFECTS OF DISCUSSION AND TEXT PLANNING STRATEGIES TO ENHANCE AND ASSESS WRITTEN COMMUNICATION SKILLS

2016

A scuola come nella vita, le capacità di comunicazione scritta sono fondamentali. Queste abilità riguardano soprattutto la costruzione di testi per usi e scopi diversi, l’elaborazione efficace delle informazioni, l’uso corretto della forma linguistica. Scrivere significa conoscere le regole grammaticali ma soprattutto riflettere sulle situazioni e sui contesti specifici di realizzazione, considerare le funzioni linguistiche, gli scopi e i bisogni comunicativi. Sempre più spesso lo sviluppo tecnologico alimenta le difficoltà di bambini e ragazzi di produrre discorsi corretti, coerenti e logicamente organizzati. Per promuovere e valutare la competenza espressiva scritta (strutturazione logica…

Bio-ecological, phytosociological and conservation aspects of relictual and disjointed populations of Simethis mattiazzi (Vandelli) Sacc. (Xanthorrho…

2012

Two populations of Simethis mattiazzi (Xanthorrhoeaceae) were recently discovered in the Channel of Sicily – (1) Punta Bassana (Marettimo Island) and (2) Mount S. Giuliano (western Sicily) – at a considerable distance from the nearest stations hitherto known, located in southern Sardinia, the Pontine Islands Archipelago and Tunisia. The taxonomical and distributive aspects of this species are analysed to highlight the relictual and biogeographical significance of the disjointed and fragmentary nuclei distributed in several small islands of the Channel of Sicily, the Italian Peninsula and North Africa. Some morphological, biological, ecological and phytosociological aspects of the two new po…

Effects of particle clustering on the plastic deformation and damage initiation of particulate reinforced composite utilizing X-ray CT data and finit…

2018

In this paper, a new simulation technique which can include microstructural inhomogeneity of particulate reinforced composites is proposed to accurately study deformation pattern and damage mechanism in these composites. Three dimensional microstructures constructed from XCT images incorporated into finite element modeling codes with minimal approximation to capture the effects of cluster size, local volume fraction of particles in the cluster and the distance between clusters as relevant statistical quantities describing the microstructural inhomogeneity of particulate reinforced composites. A quantitative parameter as degree of clustering is defined to consider particle clustering effect.…

Dexipm-Grapevine : a multicriteria assessment tool of the sustainability for grapevine farming systems

2015

The development of innovative farming systems to reach new goals of agricultural sustainability needs new methods for efficiency assessment. DEXiPM-Grapevine© is a multicriteria assessment tool for overall sustainability of grapevine farming systems adapted from DEXiPM arable crops (Pelzer et al, 2012). DEXiPM-Grapevine© was implemented during the European PURE Project 2012-2015 (Integrated Pest Management (IPM) solutions in agriculture) in order to assess and compare various innovative grapevine systems. This model includes 65 basic attributes describing the cropping system, which are then combined into 97 aggregated attributes, designed to assess the economic, social and environmental per…

2016

The CoSAC project associates partners from research and development in order to (1) quantify and understand, with experiments, the effects of novel agricultural practices on weeds and the functioning of the agroecosystem, (2) design tools that predict the effect of agricultural techniques et pedoclimate on weed flora, (3) use these tools to design sustainable weed management strategies and to evaluate their performances in contexts of changing agricultural practices, climate, biodiversity, (4) facilitate the adoption of these novel strategies by farmers. We will present the first results of the project, e.g. the effect on weeds of cover crops during fallow or associated to a cash crop, the …
