Abstract (sommario):

Passengers are more susceptible to experiencing motion sickness (MS) than drivers. The difference in the severity of MS is due to their different head movement behavior during curve driving. When negotiating a curve, the passengers tilt their heads towards the lateral acceleration direction while the drivers tilt their heads against it. Thus, to reduce the passengers’ level of MS, they need to reduce their head’s tilting angle towards the lateral acceleration direction. Designing MS minimization strategies is easier if the correlation between the head movement and lateral acceleration is known

Abstract (sommario):

The possibility of avascular changes of the metatarsal heads following forefoot surgery has been previously documented. The aim of this study was to investigate the arterial supply of the lesser metatarsal heads with regard to osteotomies of these bones. We used epoxy resin injections and a modified Spalteholz technique in human cadaveric specimens to demonstrate the intraosseous and extraosseous blood supply of the lesser metatarsals. The metatarsal heads had two arterial sources: The dorsal metatarsal arteries, which arose from the dorsalis pedis artery, and The plantar metatarsal arteries,

Abstract (sommario):

BACKGROUND Supernumerary heads of the biceps brachii are a common anatomical variation, with an incidence of 3.7 % to 20.5 % in various studies carried out around the world. They can occur in various forms, and produce a range of clinical symptoms, such as impingement syndromes at the shoulder joint, and nerve-compression syndromes in the arm. An awareness of these variations is helpful when assessing patients with pain symptoms in the region of the shoulder and arm. The purpose of this study was to examine the morphology, nerve supply, and variations in morphology, of the biceps brachii in a

Abstract (sommario):

Background: Biceps brachii derives its name from its two proximally attached parts or ‘heads’ that is known as long head and short head. Two tendons form elongated bellies that though closely applied get fused within 7cm or so above the elbow joint. These variations should be kept in mind during surgical and diagnostic procedures done by clinicians.Methods: A total of 18 cadavers were dissected for two successive years during undergraduate and were observed for different patterns of fusion of two heads of biceps brachii.Results: The present study showed that frequency of fusion of heads of bic

Abstract (sommario):

Active vision systems can be considered as systems that integrate visual sensing and action. Sensing includes detection of actions/events and results also in specific actions/manipulations. This paper mainly addresses the basic issues in the design of a head-eye system for the study of active-purposive vision. The design complexity of such a head is defined by the activeness of the visual system. Although we have not had the motivation to exactly reproduce the biological solutions in a robot, we claim that the designer should carefully consider the solutions offered by evolution.

Metal transfer to femoral heads may result from impingement against the metallic acetabular shell following subluxation/dislocation, or when metallic debris enters the articulation zone.

Profilometry revealed roughness averages in regions of metal transfer averaging 0.380 m for CoCr and 0.294 m for which were one order of magnitude higher than those from non-implanted controls.

Abstract (sommario):

We introduce and study the model of diving queue automata which are basically finite automata equipped with a storage medium that is organized as a queue. Additionally, two queue heads are provided at both ends of the queue that can move in a read-only mode inside the queue. In particular, we consider suitable time constraints and the case where only a finite number of turns on the queue is allowed. As one main result we obtain a proper queue head hierarchy, that is, two heads are better than one head, and one head is better than no head. Moreover, it is shown that the model with one queue hea

The skeletal remains represent at least seven children. Strontium isotope ratios are examined to determine whether children were taken from foreign locales. Results show that the children’s skulls exhibit a hole on the apex of the cranium and on the ascending ramus of the mandible, identical to the adult Wari trophy heads. At least one child may have been sacrificed.87Sr/8
