Estudio hospitalario del vértigo y mareo: aspectos clínicos y radiológicos
2020
Esta tesis doctoral trabaja sobre pacientes remitidos a cualquier especialidad de un hospital sin unidad de otoneurología por los síntomas vértigo y mareo. En una primera parte se analizan sus características demográficas y clínicas y se evalúan las derivaciones con el fin de obtener datos que permitan mejorar la calidad asistencial. También se analizan las pruebas de imagen realizadas en los pacientes con vértigo y mareo, para poder determinar su utilidad y establecer recomendaciones. Las conclusiones se resumen en los siguientes puntos: En el hospital hay una tasa anual de 1,6 primeras visitas por cada 1000 habitantes debido a los síntomas vértigo y mareo. De todos los pacientes derivados…
IL SITO PREISTORICO DELLO ZUBBIO DI COZZO SAN PIETRO S.I.C. RUPI DI CATALFANO E CAPO ZAFFERANO
2014
All’interno del S.I.C, “Rupi di Catalfano e Capo Zafferano”, alcune delle grotte presenti sono state frequentate dall’uomo fin dalla preistoria. Mettendo a confronto la genesi delle cavità e la loro ubicazione topografica, è evidente che la scelta dei siti consoni a essere usati dall’uomo è marcatamente strategica e ponderata. L’indagine è stata condotta dapprima individuando e raggiungendo i siti noti in bibliografia, dai quali si è cercato di elaborare un modello per individuare nuovi siti che potessero presentare evidenze di frequentazione umana risalenti alla preistoria, soprattutto recente. All’interno di una grotta, Zubbio di Cozzo San Pietro, ubicata ad una quota di 300 m s.l.m sul v…
Climate controls on the Holocene development of a subarctic lake in northern Fennoscandia
2015
International audience; Climate exerts strong control over the functioning of northern freshwater ecosystems, yet their resilience and responses to climate forcing may vary. We examined postglacial development patterns in subarctic Lake Varddoaijavri to discern the impact of direct climate controls, catchment influence, and ontogenic processes on the ecological functioning of the lake over the Holocene. Subfossil diatom assemblages together with the elemental and stable isotopic (delta C-13, delta N-15) composition of sediment organic matter were used to examine climate-induced changes in the structure of the phototrophic community and transport of terrestrial organic matter from the catchm…
Mauna Kea, Hawaii, as an Analog Site for Future Planetary Resource Exploration: Results from the 2010 ILSO-ISRU Field-Testing Campaign
2013
Within the framework of the International Lunar Surface Operation - In-Situ Resource Utilization Analogue Test held on January 27 - February 11, 2010 on the Mauna Kea volcano in Hawaii, a number of scientific instrument teams collaborated to characterize the field site and test instrument capabilities outside laboratory environments. In this paper, we provide a geological setting for this new field-test site, a description of the instruments that were tested during the 2010 ILSO-ISRU field campaign, and a short discussion for each instrument about the validity and use of the results obtained during the test. These results will form a catalogue that may serve as reference for future test cam…
On-board Energy Consumption Assessment for Symbolic Execution Models on Embedded Devices
2020
Internet of Things (IoT) applications operate in several domains while requiring seamless integration among heterogeneous objects. Regardless of the specific platform and context, IoT applications demand high energy efficiency. Adopting resource-constrained embedded devices for IoT applications means ensuring low power consumption, low maintenance costs and possibly longer battery life. Meeting these requirements is particularly arduous as programmers are not able to monitor the energy consumption of their own software during development or when applications are finally deployed. In this paper, we discuss on-board real-time energy evaluation of both hardware and software during the developm…
Determining noise and vibration exposure in conifer cross-cutting operations by using Li-Ion batteries and electric chainsaws
2018
In many activities, chainsaw users are exposed to the risk of injuries and several other hazard factors that may cause health problems. In fact, environmental and working conditions when using chainsaws result in workers&rsquo
Ecklonia maxima-derivate seaweed extract supply as mitigation strategy to alleviate drought stress in chicory plants
2023
Extreme climatic conditions have a severe repercussion on agriculture and on food availability. Ecological means to overcome drought are important to improve agroecosystems sustainability and resilience. The use of an Ecklonia maxima-derivate seaweed extract (SwE) as a tool to mitigate drought constrain in chicory plants grown in greenhouse was evaluated. Plants were cultivated in plastic pots filled with peat and subjected to drought stress by retaining moisture range at 90–100% of water holding capacity (WHC) [well-watered (WW)], 60–70% WHC [moderate drought stress (MDS)] or 30–40% WHC [severe drought stress (SDS)]. Drought stress decreased plant growth traits and yield. However, in plant…
Bridging the gap between research and practice : using phenomenographic findings to develop training for career practitioners
2021
AbstractThis study contends that phenomenography offers both a useful research method and practical tools for developing education and training for career practitioners. After introducing the basic principles of phenomenography, the study reviews previous research on its potential in developing pedagogical practices. It explores how the phenomenographic findings were utilized to design an online skills training programme for career practitioners. The study finds that phenomenographic research serves three practical pedagogical purposes: (1) revealing how learners understand certain concepts or phenomena, (2) elucidating how these understandings differ; and (3) identifying critical aspects i…
Underuse of long-term routine hospital follow-up care in patients with a history of breast cancer?
2011
Abstract Background After primary treatment for breast cancer, patients are recommended to use hospital follow-up care routinely. Long-term data on the utilization of this follow-up care are relatively rare. Methods Information regarding the utilization of routine hospital follow-up care was retrieved from hospital documents of 662 patients treated for breast cancer. Utilization of hospital follow-up care was defined as the use of follow-up care according to the guidelines in that period of time. Determinants of hospital follow up care were evaluated with multivariate analysis by generalized estimating equations (GEE). Results The median follow-up time was 9.0 (0.3-18.1) years. At fifth and…
Car sharing demand estimation and urban transport demand modelling using stated preference techniques
2008
The research deals with the use of the stated preference technique (SP) and transport demand modelling to analyse travel mode choice behaviour for commuting urban trips in Palermo, Italy. The principal aim of the study was the calibration of a demand model to forecast the modal split of the urban transport demand, allowing for the possibility of using innovative transport systems like car sharing and car pooling. In order to estimate the demand model parameters, a specific survey was carried out inside the urban area of Palermo. The survey focused on the morning rush hour and involved mainly employees, self-employed workers and students (about 500 respondents) whose final destination was lo…
