Ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry to identify contaminants in water: an insight on environment…

2013

Ultra-high pressure liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-QqTOF-MS) acquiring full scan MS data for quantification, and automatic data dependent information product ion spectra (IDA-MS/MS) without any predefinition of the ions by the user was checked for identifying organic contaminants in water samples. The use of a database with more than 2000 compounds achieved high confidence results for a wide number of contaminants based upon retention time, accurate mass, isotopic pattern and MS/MS library searching. More than 20 contaminants, mostly pharmaceuticals, but also mycotoxins and polyphenols were unambiguously identified. Furthermore, the combination of s…

HPLC determination of oxadiazon in commercial pesticide formulations

2008

A simple, fast and precise high performance liquid chromatographic (HPLC) procedure has been developed for the determination of oxadiazon in emulsifiable concentrated pesticide formulations. 20 µL of diluted sample in acetonitrile were injected in a Kromasil C18 (250 ×am injetados em uma coluna Kromasil C18 4.6 mm, 5 µm) column, using acetonitrile:water (80:20) as mobile phase at 1 mL min-1 flow rate and oxadiazon determined by absorbance measurement at 292 nm. A theoretical limit of detection of 0.02 µg mL-1, a limit of quantification of 0.047 µg mL-1, corresponding to a 0.02 and 0.07% m/v in the original sample, and a relative standard deviation of 0.08% for three replicate analysis of sa…

DIAGNOSIS-RELATED GROUP ANALYSIS AND STRATEGIC HEALTHCARE BUDGETING

2011

The term Diagnosis-Related Group DRG) refers to a classification system used to assess hospital services with the aim of streamling health care costs and improving performance. The DRG system focuses on the utilization of resources, and is not concerned with the specific type of care provided to the patient. This system highlights any diseconomies and eventual critical aspects of the hospital system. This article examines the variables used to correctly evaluate hospital performance based on the DRG system. These include: Average length of Stay, Average Daily Patients Load, Comparative Performance Index and Case Mix Index.

El rol del modelo de las competencias en la reconfiguración meritocrática de las pautas de negociación salarial en empresas argentinas: continuidades…

2020

The development of new models of work organization and the complementary advance of flexible guidelines for the use of the labor force had as a correlate a profound change in techniques for the evaluation of workers. Thus, the typical model of Fordism, based on qualifications, was replaced by a different one based on competencies, whereby the strong relationship of the former was abandoned with the determination of the technical knowledge required for each job to move to a system which the priority is placed in the individual attitude. The consequent individualization of performance evaluations can lead to a possible loss of objectivity. In this article we develop a theoretical comparison b…

The contribution of geographical certification programs to farm income and rural economies: The case of Pecorino Siciliano PDO

2021

This study attempts to measure the capacity of the EU geographical certification scheme to positively influence the price of certified products and the incomes of their producers. A comparison of the economic results of two cheese-producing dairy farm enterprises with different business strategies and locations within the Sicilian hinterlands is performed in order to determine the transformation value of each dairy’s sheep milk into pecorino cheese (with and without the Protected Designation of Origin, or PDO, certification) and the related joint products (ricotta). The economic convenience of the total transformation of sheep milk into Pecorino Siciliano PDO and ricotta is also appraised. …

A Digital Twin predictive maintenance framework of air handling units based on automatic fault detection and diagnostics

2022

The building industry consumes the most energy globally, making it a priority in energy efficiency initiatives. Heating, ventilation, and air conditioning (HVAC) systems create the heart of buildings. Stable air handling unit (AHU) functioning is vital to ensuring high efficiency and extending the life of HVAC systems. This research proposes a Digital Twin predictive maintenance framework of AHU to overcome the limitations of facility maintenance management (FMM) systems now in use in buildings. Digital Twin technology, which is still at an initial stage in the facility management industry, use Building Information Modeling (BIM), Internet of things (IoT) and semantic technologies to create…

Comunicació 2.0 i gènere

2009

Internet ha capgirat les formes de comunicació i d’intercanvi d’informació entre les persones: les receptores en el procés comunicatiu són ara també emissores. La conjunció d’aquesta particularitat amb l’aparició i ús d’algunes eines de comunicació (fàcils d’usar i bàsicament gratuïtes) permet parlar d’un fenomen social de gran abast: la comunicació 2.0. Aquest article analitza algunes de les característiques d’aquesta classe d’interacció i centra l’interés de forma particular en certes iniciatives que tenen com a epicentre les qüestions de gènere. La comunicació 2.0 permet la participació activa i directa en el procés, obert i col·laboratiu, de construcció de la identitat pròpia. Així mate…

MODELLING AND ANALYSING STUDENT DROPOUT IN COLOMBIAN HIGHER EDUCATION THROUGH POLICY AND PUBLIC MANAGEMENT

The complexity of the phenomenon of student dropout in higher education requires several modeling techniques. In this doctoral dissertation, findings of blending mathematical, statistical and Dynamic Performance Management as modelling techniques are presented to allow a deeper comprehension of Colombian student dropout in higher education.

Impact of wage penalty on mobility return of French PhDs

2015

International audience; Expatriation of higher-education graduates raises much concern in many countries often in conjunction with talk about the brain drain. It supposedly entails a risk of losing the skills required for a competitive economy. The issue is all the more acute for PhD graduates, who are expected to play a major part in the knowledge economy. However, questions arise as to the causes of such mobility and its consequences for young graduates' individual career paths.

Programming languages for data-Intensive HPC applications: A systematic mapping study

2020

This work is a result of activities from COST Action 10406 High -Performance Modelling and Simulation for Big Data Applications (cHiPSet), funded by the European Cooperation in Science and Technology. FCT, Portugal for grants: NOVA LINCS Research Laboratory Ref. UID/ CEC/ 04516/ 2019); INESC-ID Ref. UID/CEC/50021/2019; BioISI Ref. UID/MULTI/04046/2103; LASIGE Research Unit Ref. UID/CEC/00408/ 2019. A major challenge in modelling and simulation is the need to combine expertise in both software technologies and a given scientific domain. When High-Performance Computing (HPC) is required to solve a scientific problem, software development becomes a problematic issue. Considering the complexity…
