Identity in virtual communities
1998
The usability of Collaborative Virtual Environments is a function of technical affordances with the implicit and explicit intentions of users. Intentions can be revealed by 'cyborg ethnography' -- a close examination of interactions and conversations conducted in CVE's. Three CVE's were examined ethnographically and it is found that social conventions develop around the theme of producing identity. However, there is doubt that such conventions constitute evidence of a 'virtual' social system.
Survival of implants placed with the osteotome technique : an update. Review
2012
A literature review is made to analyze the survival of implants placed with the osteotome technique. A PubMed search was made based on the key words “osteotome AND dental implants”, corresponding to publications between 1998-2008. The inclusion criteria were: a) a minimum of 10 patients; b) a minimum follow-up of 6 months; c) implants placed using the osteotome technique with or without indirect sinus lift; and d) specification of the implant number and survival rate. Sixty-four articles were identified, of which 20 met the inclusion criteria. A total of 2006 implants were placed in 1312 patients using the osteotome technique. The duration of follow-up after prosthetic loading ranged from 6…
Combining conventional chemotherapy and γδ T cell-based immunotherapy to target cancer-initiating cells.
2013
According to common beliefs, conventional anticancer chemotherapy is deleterious for the immune system. We have recently provided in vitro evidence indicating that conventional chemotherapy may potentiate, rather than impair, the long-term efficacy of γδ T cell-based anticancer immunotherapy.

No. of bitstreams: 0 Previous issue date: 2010-05-01 The calcifying cystic odontogenic tumour (CCOT) is a rare benign cystic neoplasm not infrequently associated with odontoma. This report documents a case of CCOT associated with compound odontoma arising in the anterior maxilla in a 25-year-old woman. Co…
Circulating Levels of Ferritin, RDW, PTLs as Predictive Biomarkers of Postoperative Atrial Fibrillation Risk after Cardiac Surgery in Extracorporeal …
2022
Postoperative atrial fibrillation (POAF) is the most common arrhythmia after cardiac surgery in conventional extracorporeal circulation (CECC), with an incidence of 15–50%. The POAF pathophysiology is not known, and no blood biomarkers exist. However, an association between increased ferritin levels and increased AF risk, has been demonstrated. Based on such evidence, here, we evaluated the effectiveness of ferritin and other haematological parameters as POAF risk biomarkers in patients subjected to cardiac surgery. We enrolled 105 patients (mean age = 70.1 ± 7.1 years; 70 men and 35 females) with diverse heart pathologies and who were subjected to cardiothoracic surgery. Their blood sample…
Stability and marginal bone loss in implants placed using piezoelectric osteotomy versus conventional drilling: systematic review and meta-analysis.
2021
Background The main objective of this systematic review was to compare primary and secondary implant stability between placement with piezoelectric osteotomy and conventional drilling, comparing marginal bone losses as a secondary objective. Material and Methods An electronic search was conducted using PubMed (MEDLINE), Scopus, and Cochrane Library (Wiley) databases, besides a manual search. Results A total of 153 articles were retrieved, 39 from Pubmed, 44 from Scopus, and 70 from the Cochrane Library. After removing duplicates, 112 articles (1 from the manual search) were screened, and 9 were finally selected for qualitative and statistical analyses. Conclusions Piezoelectric surgery is a…
Soil water repellency assessment in olive groves in Southern and Eastern Spain
2016
Soil water repellency (SWR) has been reported under different soils, land uses and regions of the world, particularly in forest land and after wildfires, yet the understanding of this variable in agricultural lands is still rather limited. This study presents the characterization from field-based measurements of SWR in four contrasted olive groves (Olea europaea L.) in Spain in terms of different environmental conditions and management: abandoned and commercial farms under permanent cover crop, conventional tillage and herbicide use. The main objectives were [1] to evaluate the potential occurrence, intensity and persistence of soil water repellency in different types of olive groves and [2…
Long-term cropping systems and tillage management effects on soil organic carbon stocks and steady state level of C sequestration rates in a semiarid…
2010
A calcareous and clayey xeric Chromic Haploxerept of a long-term experimental site in Sicily (Italy) was sampled (0–15 cm depth) under different land use management and cropping systems (CSs) to study their effect on soil aggregate stability and organic carbon (SOC). The experimental site had three tillage managements (no till [NT], dual-layer [DL] and conventional tillage [CT]) and two CSs (durum wheat monocropping [W] and durum wheat/faba bean rotation [WB]). The annually sequestered SOC with W was 2·75-times higher than with WB. SOC concentrations were also higher. Both NT and CT management systems were the most effective in SOC sequestration whereas with DL system no C was sequestered. …

Copenhagen failure : a rhetorical treatise of how speeches unite and divide mankind
2010
The purpose of this treatise is to analyse five of the Copenhagen Climate Convention's main speeches to see how they supported or weakened the agreement possibilities in the convention. Particular focus will be on the elements that divide or unite negotiators and whether the summit's failing outcome is already built in the pre-planned speeches held at the main podium. Theoretically, the study builds on Kenneth Burke's identification thesis and Elizabeth L. Malone's climate change debate analysis. I combine these in my analysis using a revised version of Malone's argument family classification tool putting it into Burke's theoretical framework. The central concept is Burke's identification, …
