DISTRIBUTION OF CARBON STARS IN THE GALAXY

2018

A search for new faint carbon (C) stars in the Polar region δ > 55o has been accomplished by obtaining objective prism spectra in the near infrared 550 -- 900 nm on images of CCD camera of Baldone Schmidt telescope of Astrophysical observatory. The positions of stars   having color indices (J – K) > 1.3 mag in Two Micron All Sky Infrared Survey (2MASS) were selected to pick out suspicious carbon stars.Our survey is limited in brightness by J < 10 mag. 24 new carbon stars were found and their characteristics obtained. The correlative relation between Teff  and spectral gradient [757 – 685] was confirmed. Such characteristics as Teff, distance from the Sun, absolute Mk  were obtained…

Renewable polyol obtained by microwave-assisted alcoholysis of epoxidized soybean oil: Preparation, thermal properties and relaxation process

2019

[EN] The soybean oil polyol (SOP) use as feedstock in the polyurethane industry has been recently emphasized due to its excellent resistance to hydrolysis, which is also applicable in coatings and thermal insulation. In this article, the SOP was obtained by a very fast microwave-assisted alcoholysis of epoxidized soybean oil (ESO). The preparation method, thermal properties, and relaxation process were evaluated. High yields as opening and consumption epoxy group and selectivity of 99.8 mol%, 985 mol%, and 71.2 mol% were obtained. Through titrations, nuclear magnetic resonance and gel permeation chromatography were identified parameters as 0.32 mg KOH.g(-1) acid number, 190 mg KOH.g(-1) hyd…

Immersive Versus Non-immersive Experience: Exploring the Feasibility of Memory Assessment Through 360° Technology

2019

Episodic memory is essential to effectively perform a number of daily activities, as it enables individuals to consciously recall experiences within their spatial and temporal environments. Virtual Reality (VR) serves as an efficacious instrument to assess cognitive functions like attention and memory. Previous studies have adopted computer-simulated VR to assess memory, which realized greater benefits compared to traditional procedures (paper and pencil). One of the most recent trends of immersive VR experiences is the 360° technology. In order to evaluate its capabilities, this study aims to compare memory performance through two tasks: immersive task and non-immersive task. These tasks d…

A new principle to normalize plasma concentrations allowing single-sample clearance determinations in both children and adults.

1992

A sufficiently accurate quantification of renal function requiring only one plasma sample without an additional gamma-camera study has, until now, only been possible in adults. A new principle will be presented here allowing the universal application of known algorithms, regardless of the clearance substance used, by normalizing the plasma concentrations with respect to the individual body dimensions of the patients - for infants as well as for adults. In this respect, algorithms are developed for clearance determinations using technetium-99m mercaptoacetyltriglycine (99mTc-MAG3), which are based on steady-state studies as the reference. They allow the calculation of quantitative clearance …

De la encuesta a la base de datos: experiencia de trabajo de campo del estudio «Inmigración, trabajo y salud» (Proyecto ITSAL)

2011

Objective: Despite the need for information in the area of migration and health, the available data are sparse. We describe the field work in a cross-sectional study on the health of immigrant workers in Spain. Method: A convenience sample of workers from Colombia, Ecuador, Morocco and Rumania in four cities was targeted, using a block-walking approach. The outcome rates of the American Association of Public Opinion Research were estimated. Results: Of 6,504 persons approached, 71.4% were eligible contacts. Of these contacts, only 57.8% completed interviews. Response and cooperation rates were above 50%. Conclusions: Block-walking enabled surveyors to access difficult-to-reach groups. The u…

Are medical residents a "core group" for for future improvement of influenza vaccination coverage in health-care workers? A study among medical resid…

2011

Abstract Despite international recommendations, vaccination coverage among European healthcare workers, including physicians, is widely recognized as unsatisfactory. In order to plan tailored vaccination campaigns and increase future coverage, we investigated reasons for refusing vaccination and determinants associated with influenza vaccine uptake among young health care workers. A survey was carried out during September and October 2010 on medical residents attending post-graduate Schools of the Medical Faculty at the University of Palermo (Italy). Each participant completed an anonymous web-based questionnaire including items on demographic and occupational characteristics, knowledge, at…

Increased Vaccination Coverage among Adolescents and Young Adults in the District of Palermo as a Result of a Public Health Strategy to Counteract an…

2018

During the summer of 2016 four cases of invasive meningococcal disease in rapid succession among young adults in the district of Palermo, Italy, resulting in one death, were widely reported by local and national mass media. The resultant ‘epidemic panic’ among the general population overloaded the vaccination units of the Palermo district over the following months. Strategies implemented by the Sicilian and local public health authorities to counteract ‘meningitis fear’ included the following: (a) extension of active and free-of-charge anti-meningococcal tetravalent vaccination from age class 12–18 to 12–30 years old; (b) implementation of vaccination units during normal clinic hours in roo…

Immunization Campaigns and Strategies against Human Papillomavirus in Italy: The Results of a Survey to Regional and Local Health Units Representativ…

2019

Objective. The study aimed to assess the impact of HPV immunization campaigns organizational aspects, the characteristics of immunization program (vaccination targets and type of offer), and communicative strategies adopted by four Italian administrative regions on vaccination coverage observed. Methods. From November 2017 to March 2018, regional and Local Health Units (LHUs) representatives were invited to complete an online survey including 54 questions evaluating vaccination invite systems, access systems to vaccination centres, reminder and recall systems, and adverse events surveillance. An overall descriptive analysis was conducted. Since observed vaccine coverage (VC) obtained in fem…

Increased Severe Adverse Outcomes and Decreased Emergency Room Visits for Pyelonephritis: First Report of Collateral Damage during COVID-19 Pandemic …

2020

<b><i>Purpose:</i></b> The coronavirus disease 2019 (COVID-19) pandemic is disrupting urology health-care worldwide. Reduced emergency room visits resulting in adverse outcomes have most recently been reported in pediatrics and cardiology. We aimed to compare patients with emergency room visits for pyelonephritis in 2019 (pre-COVID-19 era) and within the first wave of pandemic in 2020 (COVID-19 era) with regard to the number of visits and severe adverse disease outcomes. <b><i>Methods:</i></b> We performed a retrospective multicentre study comparing characteristics and outcomes of patients with pyelonephritis, excluding patients with hydroneph…
