First case in Italy of acquired resistance to oseltamivir in an immunocompromised patient with influenza A/H1N1v infection

2010

A pandemic influenza A/H1N1v strain with the neuraminidase H274Y mutation was detected in nasal secretions of a 2-year-old leukemic patient with influenza-like illness after 18 days of treatment with oseltamivir. At baseline, no drug-resistant virus was found, while 4 days after treatment initiation a mix- ture of wild-type and mutated virus was detected. After treatment interruption, the wild type influenza virus re-emerged and became prevalent in nasal secretions after a few days, suggesting the lower fitness of the mutated virus strain. The patient slowly improved concurrently with a decrease in virus load, which resulted negative 42 days after diagnosis. No other drug-resistant influenz…

Steel-concrete bond in lightweight fiber reinforced concrete under monotonic and cyclic actions

2005

Experimental results of the local bond stress-slip relationship of reinforcing bars embedded in lightweight fiber reinforced concrete with expanded clay aggregates are presented. The effect of the following parameters were investigated: - dimension of specimens; - anchorage length; - percentages of hooked steel fibers; - geometrical ratio of transverse reinforcement; - confinement external transverse pressure. Prismatic specimens with deformed steel bars embedded for a fixed length equal to five and eight equivalent diameters were tested under both monotonic and cyclic reversal imposed displacements at the tip of the bars, in controlled displacement tests. The influence of the above mention…

Immediate loading implants: Review of the critical aspects

2018

Purpose. Modern dentistry have witnessed, a rapid and continuing evolution. Concerning the implant-rehabilitation protocols, they have beenEdizioniredefined in order to satisfy patient’s increasing expectations in terms of comfort, aesthetic and shorter treatment period. The purpose of this review is to explore the concept of implant immediate loading and the indications for clinical practice. All the critical aspects that could influence the outcomes of this treatment will also be considered. Materials and methods. Three protocols for implant load timing have been classified: immediate loading implants (ILI); early loading implants (ELI); and conventional loading implants (CLI). Two subc…

Reed canary grass transportation costs – Reducing costs and increasing feasible transportation distances

2009

Abstract Reed canary grass is used in several heat and power plants in Finland and it is estimated that about 70–80 plants could utilise reed canary grass as a co-firing fuel. Long-distance transport of reed canary grass forms a significant share of the production and delivery costs. Reed canary grass can be transported in bales or as loose matter. The density of the matter and shape of the bales influence the load-size and the cost. At present it is impossible to obtain the full load-bearing capacity of a lorry even with bales, and with light bulk matter the obtainable load is less than one-third of the load-bearing capacity of a lorry. By using Orkel local-baler it has been possible to ob…

A Modular Synthesis of Polysubstituted Indolizines

2012

The N-alkylation of pyridines with cyanohydrin triflates or α-halonitriles furnishes 1-(1-cyanoalkyl)pyridinium salts that can react with nitroolefins under basic conditions to furnish polysubstituted indolizines. Overall, the indolizine core can be constructed from a pyridine, two aldehydes, and a nitroalkane, and no undesired functional groups remain in the products. When bromoacetonitrile was used for the N-alkylation, indolizine-3-carbonitriles were obtained instead. The pyridine component may be replaced by other azines, giving rise to related heterocyclic systems.

ANALYSIS OF IMPACTS ON ELECTRIC POWER SYSTEM OPERATION OF LOAD MANAGEMENT IN RESIDENTIAL AND TERTIARY BUILDINGS

2012

Load management includes all the techniques, logics, actions and programs through which the electric utilities and the customers are able to manage loads absorption in a more prudent and efficient way; it determines economic benefits for the users, but also allows a network management and operation simpler and cheaper, determining technical and economic benefits. The present paper constitutes a detailed study of interventions and techniques to control demand in the residential and tertiary sectors and the effects that these actions have on the entire electrical system and its management. It discusses the implications of such control actions in terms of reduction of network losses and relate…

The relation between workload and personal well-being among university professors

2019

The aim of the present study was to explore the level of perceived workload of university professors and to evaluate related psychosocial risks, such as addiction to work, psychological distress, and work–life conflicts. A total of 252 professors, balanced for gender (Mean age = 48.1; DS: 5.1) from 10 different universities across Europe participated in the research. Participants completed the University’s Work Environment Survey, the Dutch Workaholism Scale, and The General Health Questionnaire. The results showed that workload, when linked to bureaucratic university practices, is a predisposing factor to a negative perception of work-related well-being among university professors.

Mood, Physical, and Mental Load in Spanish Teachers of Urban School: The Role of Intensive or Split Shift

2019

Psychosocial risk factors threaten the health of teachers, who are considered to be a group at high risk of suffering burnout syndrome. The objective of this study is to measure the levels of work satisfaction, burnout, engagement, emotional stability, fatigue, and mood of teachers, depending on their workday: intensive or split shift. A nonexperimental, descriptive–comparative research design is proposed for this study. A follow-up questionnaire has been developed to assess a teacher’s levels of physical fatigue, mental fatigue, and mood at the beginning and end of the 9 days of work analyzed. The study sample consisted of 125 teachers (102 women and 23 men) with a mean age of 38.67 years…

Burnout Syndrome in municipal health managers

2016

Resumo Introdução Os gestores municipais da saúde devem responder às demandas de suas equipes e dos pacientes do Sistema Único de Saúde, enfrentando cotidianamente situações potencialmente estressoras. A sobrecarga no trabalho pode levar à exaustão física e mental, com esgotamento dos recursos emocionais, e desencadear a Síndrome de Burnout (SB), cujas consequências podem atingir o serviço gerenciado, uma vez que, ao desempenhar essa atividade laboral, tomam-se decisões determinantes nas ações em saúde que afetam muitas pessoas. Este estudo verificou a presença da SB nos gestores municipais de saúde do Estado de São Paulo. Métodos Estudo do tipo transversal no qual foram coletados dados soc…
