Prefazione

In un contesto in continua evoluzione per effetto della globalizzazione e della rivoluzione tecnologica, la definizione del concetto di devianza e l’esplorazione dei suoi cambiamenti rendono necessaria una riflessione trasversale a diversi ambiti disciplinari, attraversando il confine tra sociologia della devianza e diritto. In a changing environment as a result of globalization and technological revolution, the definition of the concept of deviance and the exploration of its changes make necessary a cross-reflection in different disciplines, crossing the border between sociology of deviance and law.
Viaggi nell’immaginario: il turismo virtuale nel sito UNESCO di Tarragona
2023
Le nuove tecnologie hanno trasformato in modo radicale non solo la geografia come disciplina, ma anche le geografie del mondo. Il digitale ha assunto, infatti, un ruolo di mediazione sempre più pervasivo nella produzione dello spazio, come delle conoscenze e degli immaginari geografici. Le possibilità offerte dal virtuale, in particolare, offrono oggi un contributo decisivo nella comunicazione dei significati attribuiti ai luoghi e rispondono in modo sempre più efficace ai bisogni emergenti del settore turistico. Le esperienze di visita mediate dal digitale mirano a coinvolgere i sensi e risultano efficaci quando promuovono immersioni rigorosamente realistiche. Nel quadro di queste riflessi…
A new type of hydraulic cylinder system controlled by the new-type hydraulic transformer
2013
In order to enhance the efficiency of the hydraulic system, one new-type hydraulic transformer is presented in this paper. First, the basic structure and the principle of the new-type hydraulic transformer are explained. Then, the mathematical models including both the inner and outer loops are analyzed. Moreover, two kinds of control methods are discussed corresponding to the two loops, respectively. Furthermore, the proposed strategies are translated into the simulation languages, and the simulation is made in Simulink. Finally, the prototypes of new-type hydraulic transformer and the test rig are constructed to test the performance. Both the simulated and experimental results show that …
Fumador, exfumador y COVID-19: la nicotina no protege contra el SARS-CoV-2
2021
Queremos agradecer a Moril et al.1 el interés en nuestro trabajo, pues nos permite reflexionar sobre el tema. La proteína Spike del SARS-CoV-2 es la responsable de facilitar su entrada a las células humanas, requiriendo cebado por la proteasa TMPRSS2 que permite la fusión de las membranas viral y celular2. El receptor utilizado por la proteína Spike es la enzima convertidora de angiotensina 2 (ACE2)2, que se expresa en diferentes estirpes celulares, además de en el pulmón; existiendo, a nivel pulmonar, un gradiente de expresión de ACE2 (mayor expresión en vías respiratorias superiores [epitelio nasal] y menor en los neumocitos alveolares)2. Se sugiere que una mayor expresión de ACE2 podría …
A Comparison of Special Bonding Techniques for Transmission and Distribution Cables under Normal and Fault Conditions
2021
In this article, a review of the existing special bonding techniques for medium voltage and high-voltage cables is presented. Special bonding techniques have the purpose of reducing sheath currents, thereby limiting copper losses and the reduction of the ampacity of cables. The literature review shows various bonding techniques and how these have evolved over the years thanks to new technologies. Simulations of each technique are performed in MATLAB/Simulink, to compare their strengths and drawbacks both under normal conditions and in the presence of a single-line-to-ground fault.
« N'hésitez pas à mettre un petit pouce en l’air ! » : la relation entre le youtubeur Norman et son public à travers la déixis sociale
2016
Tutkimus käsittelee kuuluisan YouTube-tähti Normanin tapaa puhutella katsojiaan. Puhuttelutavat, suhde osapuolten välillä sekä muutos puhuttelutavoissa ajan kuluessa ovat tutkimuksen tärkeimpiä aiheita. Niitä lähestytään sosiaalisen deiksiksen kautta, ja tarkempana tutkimuskohteena ovat katsojiin kohdistuvat persoonapronominit sekä imperatiivimuodot, sillä ne kuvastavat hyvin vuorovaikutussuhteita ihmisten välillä ja niitä esiintyy Normanin videoissa runsaasti. Aineiston valinta perustuu paitsi satunnaisuuteen, myös tutkimuksen kannalta välttämättömään, ehdolliseen materiaalin valintaan. Kaikissa aineistoon valituissa neljässä videossa esiintyy suoria tapoja puhutella yleisöä sanallisesti. …
Morphological determination of the phototrophic community composition of biological soil crusts in coastal sand dunes in northern Germany
2022
This dataset comprises the microbial community composition of biological soil crusts in north-German sand dunes. For this we obtained enrichment cultures of phototrophic microorganisms, by placing fragments of biocrusts of the same Petri dishes as used for sequencing, in Petri dishes with Bold Basal (1N BBM) agarized medium (Bischoff and Bold 1963). Cultures were grown under standard laboratory conditions: with a 12-hour alteration of light and dark phases and irradiation of 25 μmol photons m-2 s-1 at a temperature 20 ± 5 ºС. Microscopic study of these raw cultures began in the third week of cultivation. Morphological examinations were performed using Olympus BX53 light microscope with Noma…

Timeout procedure in paediatric surgery: effective tool or lip service? A randomised prospective observational study.
2021
BackgroundFor over a decade, the preoperative timeout procedure has been implemented in most paediatric surgery units. However, the impact of this intervention has not been systematically studied. This study evaluates whether purposefully introduced errors during the timeout routine are detected and reported by the operating team members.MethodsAfter ethics board approval and informed consent, deliberate errors were randomly and clandestinely introduced into the timeout routine for elective surgical procedures by a paediatric surgery attending. Errors were randomly selected among wrong name, site, side, allergy, intervention, birthdate and gender items. The main outcome measure was how freq…
Prevalence of tick-borne pathogens in ticks collected from migratory birds in Latvia.
2014
Migratory birds act as hosts and long-distance vectors for several tick-borne infectious agents. Here, feeding Ixodes ticks were collected from migratory birds during the autumn migration period in Latvia and screened for the presence of epidemiologically important non-viral pathogens. A total of 93 DNA samples of ticks (37 larvae and 56 nymphs) removed from 41 birds (order Passeriformes, 9 species) was tested for Lyme borreliosis spirochaetes, Anaplasma phagocytophilum, Rickettsia spp., and Babesia spp. Borrelia burgdorferi DNA was detected in 18% of the tick samples, and a majority of infected ticks were from thrush (Turdus spp.) birds. Among the infected ticks, Borrelia valaisiana was de…
