The working alliance in a randomized controlled trial comparing Internet-based self-help and face-to-face cognitive behavior therapy for chronic tinn…
2014
Objective This study (ID: NCT01205906) compared the impact of the working alliance between the therapist and the client on treatment outcome in a group and an Internet-based cognitive behavior therapy (GCBT vs. ICBT) for chronic tinnitus. Methods The Working Alliance Inventory — Short Revised (WAI-SR, scale range: 1–5) was administered to 26 GCBT and 38 ICBT participants after treatment weeks 2, 5, and 9, and the Tinnitus Handicap Inventory (THI) before and after the treatment. Results High alliance ratings were found in both ICBT (WAI-SR total scores at week 9: M = 3.59, SD = 0.72) and GCBT (WAI-SR total scores at week 9: M = 4.20, SD = 0.49), but significantly higher ratings occurred in G…
Status of ITER TBM port plug conceptual design and analyses
2014
The test blanket module port plug (TBM PP) consists of a TBM frame and two TBM-sets. However, at any time of the ITER operation, a TBM set can be replaced by a dummy TBM. The frame provides a standardized interface with the vacuum vessel (VV)/port structure and provides thermal isolation from the shield blanket. As one of the plasma-facing components, it shall withstand heat loads while at the same time provide adequate neutron shielding for the VV and magnet coils. The frame design shall provide a stable engineering solution to hold TBM-sets and also provide a mean for rapid remote handling replacement and refurbishment. This paper presents main design features of the conceptual design of …
Blind Radio Tomography
2018
From the attenuation measurements collected by a network of spatially distributed sensors, radio tomography constructs spatial loss fields (SLFs) that quantify absorption of radiofrequency waves at each location. These SLFs can be used for interference prediction in (possibly cognitive) wireless communication networks, for environmental monitoring or intrusion detection in surveillance applications, for through-the-wall imaging, for survivor localization after earthquakes or fires, etc. The cornerstone of radio tomography is to model attenuation as the bidimensional integral of the SLF of interest scaled by a weight function. Unfortunately, existing approaches (i) rely on heuristic assumpti…
Disturbing loads identification in power systems: a single-point time-domain method based on IEEE 1459-2000
2009
This paper presents a single-point method for the identification of prevailing disturbing loads in power systems for both single-phase and three-phase applications downstream or upstream from the metering section. It is based on the simultaneous measurement of three nonactive power quantities, which are based on the IEEE Std. 1459-2000 approach. The proposed method is only based on the separation of the fundamental components from the harmonic content of voltage and current; thus, it does not require any spectral analysis of the voltages and current. In this paper, the formulation of the proposed method and its time-domain implementation are described; moreover, some simulation results are …
Familiarity and visit characteristics as determinants of tourists' experience at a cruise destination
2019
Abstract The main aim of this study was to examine the differences in the interrelationships between destination image-satisfaction-behavioural intention across cruise tourists with varying visit characteristics (length of stay and type of visit arrangement) and familiarity. The data for the study was obtained through interviews with cruise passengers visiting a major Spanish port of call. The results revealed that both familiarity (informational and behavioural) and type of visit arrangement (excursion versus independent visit) moderated the hypothesized structural relationships. The moderating role of length of stay onshore was only demonstrated on the impact of satisfaction on behavioura…
The moderating effect of personal and situational characteristics in behavioural factors affecting ports of call
2017
This research aims to study the moderating effects of cruise passengers’ gender, age, education, and prior experiences on a Mediterranean port of call destination image formation and the influence ...
Cruise passengers' behavior at the destination: Investigation using GPS technology
2016
This paper aims at segmenting cruise passengers in order to identify passengers' profiles according to their behavior at destination. Through an integrated use of traditional survey instruments and of GPS technologies, a set of indicators for the analysis of passengers' mobility at destination is proposed. Data collected in the port of Palermo are used in order to investigate space-time activities of cruise passengers at the destination. Monothetic Analysis is used in order to segment passengers according to their behavior at destination, and groups are then compared in terms of socio-demographic characteristics and other variables collected through questionnaire-based survey. Results ident…
La biomonitorización de sustancias tóxicas en muestras biológicas de población general
2016
ResumenLa biomonitorización de sustancias tóxicas ha sido incorporada por buena parte de los países más desarrollados, con el objetivo de conocer sus concentraciones en muestras biológicas. Estas sustancias se incorporan al organismo por medio de diferentes exposiciones ambientales. La vigilancia en muestras biológicas debe permitir conocer sus valores en grupos vulnerables y su evolución en el tiempo, comparar con los valores observados en otros países, identificar grupos que presenten valores altos o de riesgo, y promover la investigación. Su finalidad más clara es la de servir como instrumento para el diseño de políticas que permitan poner en marcha medidas de actuación en diversos secto…

1999
The tremendous development of physical methods of analysis offers an impressive number of tools to simultaneously determine a large number of elements and compounds at very low concentration levels. Todays Analytical Chemistry provides appropriate media to solve technical problems and to obtain correct information about chemical systems in order to take the most appropriate decisions for problem solving. In recent years the development of new strategies for sampling, sample treatment and data exploitation through the research on field sampling, microwaveassisted procedures and chemometrics, additionally the revolution of the analytical methodology provided by the development of flow analysi…
STUDIES ON THE CONSTRUCTION AND FUNCTIONING OF MACHINES FOR FERTILIZER DISTRIBUTION
1970
SUMMARY The researches were made on the machine of fertiliz er distribution MA 3,5, which has a capacity of 3,5 m 3 . It is used for transport and spreading solid chem ical fertilizers. It is tracted by tractor U 650 and is actioned from the p ower prize of tractor and from the right support wheels. This machine is formed of frame with catching equipment, bin, distribution equipment, transmision and mechanisms of adjustment and getting in function. The metal frame is supported by 2 pairs of wheels w ith tires, which afford a big mobility during work to the machine . . The distributor is of centrifugal type, formed of a horizontal disc with 6 pallets with adjusted position. Above the disc is…
