The role of the aquifer in soil CO2 degassing in volcanic peripheral areas: A case study of Stromboli Island (Italy)
2017
Abstract The peripheral area of Stromboli Island, Italy, named “Scari”, was continuously studied between January 2009 and December 2010. Data on soil CO 2 flux and the partial pressure of CO 2 (pCO 2 ) in equilibrium with the thermal aquifer linked to the magmatic system are presented. Soil CO 2 fluxes range from 20 to 370 g m − 2 d − 1 and have been strongly affected by soil temperature variations. Soil CO 2 flux data were filtered with respect to the soil temperature and the calculated values, called “residuals”, were considered to detect changes induced by the magmatic system. The pCO 2 values change in a wide range from 0.03 to 0.6 (atm), showing rapid variations. The results of this s…
Cultural adaptation of the Smiling is Fun program for the treatment of depression in the Ecuadorian public health care system: A study protocol for a…
2021
Background Depression is one of the world's major health problems. Due to its high prevalence, it constitutes the first cause of disability among the Americas, where only a very low percentage of the population receives the adequate evidence-based psychological treatment. Internet-Based Interventions (IBIs) are a great alternative to reduce the treatment gap for mental disorders. Although there are several studies in low-and middle-income countries proving IBIs' feasibility and acceptability, there is still little evidence of the effectiveness in diverse social and cultural contexts such as Latin America. Methods Two studies will be described: Study 1 is focused on the cultural adaptation o…
On-body and off-body transmit power control in IEEE 802.15.6 scheduled access networks
2014
Wireless Body Area Networks (WBANs) have received much attention due to the possibility to be used in healthcare applications. For these applications, energy saving is a critical issue, as in many cases, batteries cannot be easily replaced. A transmit power control scheme, able to adapt to the variations of the wireless body channel, will allow consistent energy saving and longer battery life. In this paper we propose a transmit power control scheme suitable for IEEE 802.15.6 narrowband scheduled access networks, in which the transmission power is modulated frame by frame according to a run-time estimation of the channel propagation conditions. A simple and effective line search algorithm i…
DNA Methylation and Non-Coding RNAs during Tissue-Injury Associated Pain.
2022
While about half of the population experience persistent pain associated with tissue damages during their lifetime, current symptom-based approaches often fail to reduce such pain to a satisfactory level. To provide better patient care, mechanism-based analgesic approaches must be developed, which necessitates a comprehensive understanding of the nociceptive mechanism leading to tissue injury-associated persistent pain. Epigenetic events leading the altered transcription in the nervous system are pivotal in the maintenance of pain in tissue injury. However, the mechanisms through which those events contribute to the persistence of pain are not fully understood. This review provides a summar…
Continuous 3-year outdoor operation of a flat-panel membrane photobioreactor to treat effluent from an anaerobic membrane bioreactor
2020
[EN] A membrane photobioreactor (MPBR) plant was operated continuously for 3 years to evaluate the separate effects of different factors, including: biomass and hydraulic retention times (BRT, HRT), light path (Lp), nitrification rate (NOxR), nutrient loading rates (NLR, PLR) and others. The overall effect of all these parameters which influence MPBR performance had not previously been assessed. The multivariate projection approach chosen for this study provided a good description of the collected data and facilitated their visualisation and interpretation. Forty variables used to control and assess MPBR performance were evaluated during three years of continuous outdoor operation by means …
Bezpilota motorizētas iekārtas orientēšanās telpā un optimālā maršruta izvēle
2016
Šajā darbā tiek apskatīta un risināta austoša problēma ar autonomu “robotu” orientēšanos telpā, bez iepriekšējām priekšzināšanām par to, optimālu maršruta izvēli, kā arī risinājums, kā to izveidot neatkarīgi no ārējiem resursiem, piemēram, globālās pozicionēšanas sistēmām, mobilo datu pieslēguma datiem, bezvadu tīklu vai radio frekvenču identifikāciju. Risinājums veidots kā vairāku sensoru kombinācija, iekļaujot sevī 10 dimensiju jeb DOF, ultraskaņas un vibrāciju sensorus. Rezultātā ir iegūta sistēmas koncepcija, kura pati spēj autonomi apstaigāt lauku, paralēli veidojot apstaigātās platības karti.

Narratives Around Iberian Culture at Valencia Museums and Archaeological Sites: From Official Discourses to Social Perceptions
2016
Los museos y los yacimientos arqueológicos constituyen los espacios más autorizados para hablar sobre el pasado y el patrimonio desde un punto de vista científico. Como tales, sus discursos son asumidos por los visitantes como veraces y rara vez son puestos en duda o contestados. Sin embargo, desde la arqueología debemos plantear una mirada crítica sobre las narrativas que se generan en estos espacios patrimoniales y el impacto que tienen sobre los visitantes, pues con frecuencia traducen y sancionan realidades políticas, sociales e identitarias que tienen más que ver con el presente que con el pasado. En este trabajo nos proponemos analizar los discursos oficiales sobre la cultura ibérica …
A simple and efficient face detection algorithm for video database applications
2000
The objective of this work is to provide a simple and yet efficient tool to detect human faces in video sequences. This information can be very useful for many applications such as video indexing and video browsing. In particular the paper focuses on the significant improvements made to our face detection algorithm presented by Albiol, Bouman and Delp (see IEEE Int. Conference on Image Processing, Kobe, Japan, 1999). Specifically, a novel approach to retrieve skin-like homogeneous regions is presented, which is later used to retrieve face images. Good results have been obtained for a large variety of video sequences. Peer Reviewed
