BACKGROUND The ultraviolet properties of textiles dyed with synthetic dyes have been widely reported in literature. However, no study has investigated the ultraviolet properties of natural fabrics dyed with natural colorants. This study reports the Ultraviolet Protection Factor (UPF) of cotton fabrics dyed with colorants of plant and insect origins. METHODS Three cotton fabrics were dyed with...
OBJECTIVES Obstructive sleep apnea (OSA) is a common disorder affecting at least 2% to 4% of adult population characterized by the collapse of the pharyngeal airway. It is well established that retropalatal region is the most common site of obstruction. Consequently, many surgical techniques have been introduced. The purpose of this study is to present our preliminary results in the anterior pa...
The solar erythemal UV irradiances through human hair and the protection from UV provided by human head hair have been investigated for a solar zenith angle (SZA) range of 17-51 degrees for the conditions of a head upright in full sun, a head upright in shade and a head in full sun tilted toward the sun. The two hair lengths investigated were 49.1 +/- 7.1 mm for the short type and 109.5 +/- 5.5...
In this paper we present a benchmarking framework for the validation of cardiac motion analysis algorithms. The reported methods are the response to an open challenge that was issued to the medical imaging community through a MICCAI workshop. The database included magnetic resonance (MR) and 3D ultrasound (3DUS) datasets from a dynamic phantom and 15 healthy volunteers. Participants processed 3...
Rationale: Ultra-processed food (UPF) consumption has been associated with increased risk of cardiovascular factors and mortality. However, little is known on the UPF effect renal function. The aim this study to assess prospectively association between function decline.

Abstract—Recently, direct-type ac-ac converters have attracted considerable attention for voltage magnitude variation due to the reduced number of component requirements. This paper introduces a direct single-phase converter with novel switching strategy UPF and non-UPF load. The suggested converter's circuit configuration uses six power MOSFETs two inductors at high frequency reduce size. prop...

We present the Unified Policy Framework (UPF), a generic framework for modelling security (access-control) policies; in Isabelle/HOL. UPF emphasizes the view that a policy is a policy decision function that grants or denies access to resources, permissions, etc. In other words, instead of modelling the relations of permitted or prohibited requests directly, we model the concrete function that i...
