A Model for Assessing the Magnitude and Distribution of Sheath Currents in Medium and High-Voltage Cable Lines

2020

In this article, the authors discuss a simulation model to study the effect of cross-bonding of metallic sheaths, and/or nonmagnetic armors, of single-core medium- and high-voltage cables in the same circuit. In single-core cables, the resistive losses due to the induced circulating currents in cable sheaths or armors cause an increase of the cable temperature, which therefore reduces its ampacity. This is a serious issue affecting the distribution and transmission lines. In addition, the risk of electric shock due to induced voltages may be present if a person is in contact with the armor/sheath at its unbounded end. For these reasons, special bonding techniques of metal sheaths are employ…

Polymorphism and versatile solvate formation of thiophanate-methyl

2009

The polymorphism of a fungicide, thiophanate-methyl (TM), was investigated with conventional solvent screening methods. Two polymorphs, the thermodynamically most stable form I and the less stable form II, were found. TM was also found to crystallize as a plethora of different solvates which produced mostly form II upon desolvation. The structures of form I and form II and the fourteen discovered solvates were solved by single crystal X-ray diffraction. The most stable forms were further characterized by powder diffraction, thermoanalytical (TG/DTA, DSC and thermomicroscopy) and spectroscopic (IR, Raman, ¹³C CP/MAS NMR) methods. peerReviewed

Cybersex in the “Net generation”: Online sexual activities among Spanish adolescents

2016

The internet offers several opportunities to explore sexuality among adolescents. However, some studies have also revealed problematic effects of cybersex in earlier stages. Despite this, few studies analyze the online sexual behavior among adolescents, even less in Spain where there is very little data. For this reason, our aim is to examine the use of internet for sexual purposes among Spanish adolescents, including gender differences. Three hundred and twenty-two adolescents completed an ad-hoc questionnaire and the Spanish version of the Internet Sex Screening Test. In general, boys report more cybersex than girls do, for example, in masturbating while the Internet (60.6% of boys and 7.…

IMPRESSIONI IN SICILIA

2014

“Impressioni in Sicilia” è la storia di una piccola azienda di design tessile che ha operato a Palermo dal 1974 fino al 1994. Proprietaria dell’impresa è Regine Hildebrandt, una svizzera trapiantata in Sicilia. La nascita di questo laboratorio s’inserisce in quel filone di esperienze finalizzate a incentivare il processo che vede l’incontro tra la cultura del progetto e la produzione artigianale, spesso legata alle tradizioni e alle risorse di alcuni territori. Gli oggetti progettati e realizzati da Regine hanno un valore durevole per la qualità dei disegni e dei materiali ma soprattutto, perché il suo progetto di ricerca è destinato all’identificazione e alla proposizione di “tratti cultur…

Cinematic dialogue, literary dialogue, and the art of adaptation : dialogue metamorphosis in the film adaptation of The green mile

Design and rationale of a nationwide screening analysis from the LIPIDOGRAM2015 and LIPIDOGEN2015 studies.

2022

IntroductionCardiovascular disease (CVD) is a major cause of morbidity and mortality throughout the world. The LIPIDOGRAM2015 study was performed to estimate the prevalence of risk factors for atherosclerotic diseases as well as cardiovascular and related disorders in the primary care setting in Poland. The LIPIDOGEN2015 sub-study was designed to include a random cohort of patients in order to analyse parameters related to lipid metabolism, oxidative stress, inflammatory responses, autoimmune disorders, and gene variants that confer susceptibility to cardiometabolic and atherosclerotic diseases.Material and methodsThe recruitment was carried out by 438 primary care physicians in Poland. The…

Prevalence of lumbosacral radiculopathy in two Sicilian municipalities

2009

Objectives - As part of a door-to-door survey of neurologic diseases, we investigated the prevalence of lumbosacral radiculopathy (LR) in two Sicilian municipalities (N = 14,540, as of November 1, 1987). Material & methods - During phase 1, we administered a brief screening instrument to subjects in the study population. In phase 2, study neurologists using specified diagnostic criteria investigated those subjects who screened positive. Our case finding was restricted to subjects who manifested symptoms of LR in the six months preceding the prevalence day. Results - We found 143 subjects affected by LR (112 definite, 31 possible) yielding a crude prevalence of 9.8 cases per 1,000 population…

Cancer colorectal : du diagnostic au dépistage

2009

Colorectal cancer fulfils the conditions required for mass screening. Data from controlled studies indicate that it is possible to reduce colorectal cancer mortality at a population level using faecal occult blood testing. Screenings rely on biennial testing in between 50 and 74average risk subjects. Compliance must be over 50%. Colorectal cancer mortality decrease in this case between 15 and 18% in the general population, 33 and 39% among participants to screening. The European Commission, on the basis of available data recommended to organise colorectal cancer screening in the European Union. Generalisation of screening has become a reality in France. Epidemiological studies allow us to d…

Improved calculations of beta decay backgrounds to new physics in liquid xenon detectors

2020

We present high-precision theoretical predictions for the electron energy spectra for the ground-state to ground-state $\beta$ decays of $^{214}$Pb, $^{212}$Pb, and $^{85}$Kr most relevant to the background of liquid xenon dark matter detectors. The effects of nuclear structure on the spectral shapes are taken into account using large-scale shell model calculations. Final spectra also include atomic screening and exchange effects. The impact of nuclear structure effects on the $^{214}$Pb and $^{212}$Pb spectra below $\approx100$ keV, pertinent for several searches for new physics, are found to be comparatively larger than those from the atomic effects alone. We find that the full calculatio…
