Snow stratigraphic heterogeneity within ground-based passive microwave radiometer footprints: implications for emission modeling

open access: yes, 2014
Two-dimensional measurements of snowpack properties (stratigraphic layering, density, grain size and temperature) were used as inputs to the multi-layer Helsinki University of Technology (HUT) microwave emission model at a centimeter-scale horizontal ...

Automated ice-sheet snowmelt detection using microwave radiometer measurements

open access: yesPolar Research, 2013
Monitoring ice-sheet snowmelt is fundamental to understanding global climate change. A simple and automated snowmelt detection process is critical to the establishment of an ice-sheet snowmelt monitoring system.

Probable sepsis‐associated encephalopathy as a component of multiple organ dysfunction syndrome in a cat with pyothorax

open access: yesAustralian Veterinary Journal, EarlyView.
A 2‐year‐old male neutered domestic shorthair cat with bacterial pyothorax was referred to a tertiary hospital for treatment of sepsis. He met criteria for multiple organ dysfunction syndrome and developed new‐onset neurological dysfunction subsequent to the development of sepsis.

Design and First Results of an UAV-Borne L-Band Radiometer for Multiple Monitoring Purposes

open access: yesRemote Sensing, 2010
UAV (unmanned Aerial Vehicle) platforms represent a challenging opportunity for the deployment of a number of remote sensors. These vehicles are a cost-effective option in front of manned aerial vehicles (planes and helicopters), are easy to deploy due ...

Disproportional ventilatory response to incremental exercise in individuals with cerebral palsy

open access: yesDevelopmental Medicine &Child Neurology, EarlyView.
Individuals with cerebral palsy demonstrate a disproportionate ventilatory response during incremental exercise. Compared with typically developing peers, respiratory frequency increases earlier and at comparable exercise intensities, contributing to higher perceived exertion and reduced ventilatory efficiency. At task failure, respiratory frequency is

Radiometals in Diagnosis and Therapy [PDF]

open access: yesMetal-Based Drugs, 1997
Radiometals are the mainstay of both diagnostic and therapeutic nuclear medicine because the choice of radionuclide is primarily dictated by nuclear decay characteristics rather than chemistry.  99mTc is the most frequently used diagnostic radionuclide and requires coordination in a diversity of chemical disguises to permit imaging of a variety of ...

Fracture load and three‐dimensional internal void analysis of direct composites used to restore worn molars

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This study evaluated (1) the load‐bearing capacity of molars restored with direct occlusal veneers fabricated either from short‐fiber‐reinforced composite (SFRC) or particulate‐filled composite (PFC) and the presence of internal voids within the materials, and (2) effect of water storage on the fracture load and correlation between internal ...

Variability and uncertainty in measuring sea surface temperature

open access: yes, 2012
Sea Surface Temperature (SST) measurement is one of the most easily obtainable climate variables. However, it is challenging to meet the required absolute accuracy and long term stability whether the data are derived by in situ or satellite measurements.

Middle-atmospheric wind measurements by the ground-based passive radiometer WIRA-C [PDF]

open access: yes, 2020
This thesis is dedicated to the measurement of wind in the middle-atmosphere, more precisely, zonal and meridional wind in the stratosphere and lower mesosphere from 30 to 70~km altitude. Dynamics in the middle atmosphere have an impact on life on Earth,

Influence of rubbing during etching on surface roughness and interfacial characteristics of intact enamel

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract Rubbing phosphoric acid during etching has been shown to improve surface roughness in prepared enamel. This study aimed to compare intact enamel's surface roughness and resin tag lengths after etching with and without rubbing. Extracted sound third molars were used for testing, mesially for conventional and distally for dynamic (rubbing ...
