The field of work in Brazil--a paradoxical reality.
The opportunity to present part of the construction of the knowledge of Brazil in the field of work is rewarding. This presentation allows sharing issues that arise, sometimes so close, sometimes so far away from other global realities. The research and the pursuit of knowledge in the field of work, as it could be expected, reflecting the continental dimensions of Brazil, a country of many cont...
متن کاملAugmented Reality Guidance for Needle Biopsies: A Randomized, Controlled Trial in Phantoms
We report the results of a randomized, controlled trial to compare the accuracy of standard ultrasound-guided needle biopsy to biopsies performed using a 3D Augmented Reality (AR) guidance system. Fifty core biopsies of breast phantoms were conducted by a board-certified radiologist, with each set of five biopsies randomly assigned to one of the methods. The raw ultrasound data from each biopsy...
متن کاملAugmented reality guidance for needle biopsies: An initial randomized, controlled trial in phantoms
We report the results of a randomized, controlled trial to compare the accuracy of standard ultrasound-guided needle biopsy to biopsies performed using a 3D Augmented Reality (AR) guidance system. A board-certified radiologist conducted 50 core biopsies of breast phantoms, with biopsies randomly assigned to one of the methods in blocks of five biopsies each. The raw ultrasound data from each bi...
متن کاملPhantoms of the brain.
8 Theorists calculate that this drastic change in the structure of matter sets in over a narrow range of temperatures centred around 10 12 K. To gauge the change, it is instructive to compare the degrees of freedom — the number of different particles that energy can go to. On the hadronic side of the transition, the important particles at these temperatures are just the pions (the other hadrons...
متن کاملCaffeine attenuates paradoxical sleep deprivation induced- memory impairment during paradoxical sleep windows in rats
There is considerable evidence to support the hypothesis of relationship between paradoxical sleep (PS) and learning–memory processing. It has been suggested that PS is important in memory retention at the specific time course called PS windows (PSW). The time of PSWs occurrence and duration of these PSWs following the training sessions and, the neurochemical nature of PSWs has not been well kn...
