Evidence‐based review of the effects of nutritional supplementation for pressure ulcer prevention

open access: yesInternational Wound Journal, Volume 18, Issue 6, Page 805-821, December 2021., 2021
Abstract The objective of this evidence‐based review was to explore whether the evidence supports the use of nutritional supplements in pressure ulcer (PU) prevention strategies. Several electronic databases, including Ovid MEDLINE (1946 to May week 32 019), Ovid EMBASE (1947 to May 28, 2019), EBSCO CINAHL (until June 13, 2019), Scopus (until July 9 ...

Measuring the impact of ride‐hailing firms on urban congestion: The case of Uber in Europe

open access: yesPapers in Regional Science, Volume 100, Issue 5, Page 1230-1253, October 2021., 2021
Abstract This paper examines the impact of Uber, the world's largest ride‐hailing firm, on congestion. Drawing on data from European cities for the period 2008 through 2016, I find a negative impact of Uber on congestion. The estimated impact in the baseline regression is −3.5 percentage points, but it is higher in cities that do not impose strong ...

Comprehensive Indicator Bank for Resilience of Water Supply Systems

open access: yesAdvances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021
Appropriate indicators are required to measure the resilience of water supply systems (WSSs). However, it is challenging to identify appropriate indicators since there is no comprehensive database of indicators to measure its resiliency. This study will establish a comprehensive bank of indicators to assist water corporations and decision‐makers in ...

Radiopurity Study of an Encapsulated CeBr3 Crystal [PDF]

open access: yesProceedings of the Conference on Advances in Radioactive Isotope Science (ARIS2014), 2015
We report on the investigation of the intrinsic activity of a commercially available CeBr3 inorganic cylindrical scintillator, 30 mm in diameter and 30 mm in height. The study has been performed by measuring gamma emissions from the encapsulated crystal at the ultralow level radioactivity laboratory at the Laboratorio Subterraneo de Canfranc (LSC). Our
