Clinical parameters of implants placed in healed sites using flapped and flapless techniques: A systematic review

2017

Background: Dental implant placement using flapless surgery is a minimally invasive technique that improves blood supply compared with flapped surgery. However, the flapless technique does not provide access to allow bone regeneration. Objectives: The aim of this systematic review was to evaluate the clinical parameters following implant surgery in healed sites, using two procedures: flapped vs. flapless surgery. Material and Methods: A detailed electronic search was carried out in the PubMed/Medline, Embase and Cochrane Library databases. The focused question was, “How do flapped and flapless surgical techniques affect the clinical parameters of dental implants placed in healed sites?”. Al…

Exploring Training Options for RF Sensing Using CSI

2018

This work analyzes human behavior recognition approaches using WiFi channel state information from the perhaps less usual point of view of training and calibration needs. With the help of selected literature examples, as well as with more detailed experimental insights on our own Doppler spectrum-based approach for physical motion/presence/cardinality detection, we first classify the diverse forms of training so far employed into three main categories (trained, trained-once, and training-free). We further discuss under which conditions it is possible to move toward lighter forms of calibration or even succeed in devising fully untrained model-based solutions. Our take home messages are main…

Willingness to Communicate in a Foreign Language: Evidence from Those Who Approach and Those Who Avoid L2 Communication

2014

It is still unclear why some learners are willing to communicate in a foreign language while others are disinclined to do so. One of the most promising paths of inquiry in this respect is the study of willingness to communicate (WTC), focusing on the volitional process of initiating, maintaining, and terminating communication. That is the reason why the main purpose of this paper is to investigate the testimonials of Polish students with persistently low or high L2 WTC scores obtained during their 3-year secondary grammar school experience. The qualitative results of the study appear to demonstrate that, independently from the individual’s general predilections towards communication in the …

La questione abitativa in Sicilia

2011

Da qualche anno la questione abitativa ha assunto una nuova centralità. Il mercato immobiliare, infatti, risponde con sempre maggiore difficoltà ai fabbisogni delle fasce sociali più deboli. L'articolo vuole restituire, in particolare, quanto sta accedendo oggi in Sicilia in materia di politiche abitative.

Ai margini delle politiche sociali. Il disagio abitativo tra nuovi contesti e nuovi soggetti

2012

Come i programmi complessi hanno contribuito ad innovare le politiche abitative in Italia? A partire da tale interrogativo, il saggio cerca di comprendere quali elementi possono essere utili per la costruzione di una rinnovata poltica abitativa nel mutato contesto socio-economico. In particolare l'articolo si sofferma sul contributo che i programmi complessi hanno dato al ripensamento delle tradizionali politiche per la casa.

Urban Air Quality Monitoring Using Vehicular Sensor Networks

2014

The quality of air is a major concern in modern cities as pollutants have been demonstrated to have significant impact on human health. Networks of fixed monitoring stations have been deployed in urban areas to provide authorities with data to define and enforce dynamically policies to reduce pollutants, for instance by issuing traffic regulation measures. However, fixed networks require careful placement of monitoring stations to be effective. Moreover, changes in urban arrangement, activities, or regulations may affect considerably the monitoring model, especially when budget constraints prevent from relocating stations or adding new ones to the network. In this chapter we discuss a diffe…

Geochemical characterization of surface waters and groundwater resources in the Managua area (Nicaragua, Central America)

2008

This paper reports new geochemical data on dissolved major and minor constituents in surface waters and ground waters collected in the Managua region (Nicaragua), and provides a preliminary characterization of the hydrogeochemical processes governing the natural water evolution in this area. The peculiar geological features of the study site, an active tectonic region (Nicaragua Depression) characterized by active volcanism and thermalism, combined with significant anthropogenic pressure, contribute to a complex evolution of water chemistry, which results from the simultaneous action of several geochemical processes such as evaporation, rock leaching, mixing with saline brines of natural or…

Relationship between UVB and broadband solar radiation in Spain

2014

The daily values of UVB irradiation (290–315 nm), IUVB, and the broadband total irradiation (300–2800 nm), IT, measured on a horizontal plane have been correlated for the period 2000–2008 at 16 measurement sites in Spain. The results have been compared with the daily experimental values registered at the same sites during the period 2009–2011. The coefficients of determination R2 obtained by applying a linear regression are higher than 0.88 for all sites and increase to 0.94 when using a quadratic regression. When all data are considered together, the values of R2 are 0.91 and 0.97 for the linear and quadratic regressions, respectively. Three different clearness indices, which are dimension…

Risk factors of Oral cancer- A hospital based case control study

2018

Background Oral cancer is a highly prevalent malignancy in Pakistan. Among various risk factors associated with this neoplasm, habits such as smoked and smokeless tobacco usage, betel quid, and betel nut consumption are the major culprits in our society. In the present study, we aimed to ascertain prevalent risk factors for OC in our population and to compare our findings with healthy controls to establish their significance. Material and methods A hospital-based case control study was conducted at Dow University of Health Sciences, Pakistan from January 2015 - September 2016. Information pertaining to unhealthy oral habits was obtained from 62 oral cancer patients (cases) and 62 healthy co…
