The objective of this study was to quantify by echography the changes in the intramuscular [gastrocnemius (Gast)] and nonintramuscular [posterior tibial (Tib)] calf veins cross-sectional area (CSA) and the superficial tissue thickness (STth) in response to lower body negative pressure (LBNP) after 60-day head-down bed rest (HDBR). Twenty-four healthy women (25-40 yr) were divided into three gro...

The dry sliding wear behavior of as-cast pristine and boron-modified Ti-6Al-4V (Ti64) alloys (having 0.3 0.55 wt% B) is investigated using pin-on-disc experiments with the pin being Ti64 alloy EN31 steel disc. Experiments are performed at speeds (s) 1, 2, 4 m/s temperatures 300 573 K. A mixed response in observed. At lowest speed, all three (except 0.55B K) exhibit similar rates, abrasive domin...

Apathy is the most frequently reported neuropsychiatric symptom across all stages of Alzheimer's disease (AD). Both apathy and sleep disorders are known to have independent negative effects on the quality of life in individuals with AD. The aim of this study was to assess the relationship between apathy and sleep/wake patterns in individuals with AD using ambulatory actigraphy. One hundred and ...

For centuries two-dimensional presentations of objects have been predominant in the depiction of architecture. In building research traditional methods still establish the basis supported by geodesic instruments – like the tachymeter – as an integral part of fieldwork, whose results will then be transferred into CAD plans by means of point clouds. As digital technologies are gradually taking ov...

In the cat, section of all cutaneous nerves of the hindfeet except the tibial (Tib) nerve supplying the plantar surface results in a long-lasting decrease in the intensity of Tib stimulation needed for a threshold response in flexor muscles and an increase in the amplitude of the phase-dependent responses recorded in various muscles during locomotion. Stimulating through chronically implanted n...
