Kinematic Analysis of Postural Stability During Ballet Turns (pirouettes) in Experienced and Novice Dancers

open access: yesFrontiers in Bioengineering and Biotechnology, 2019
Turning is an important but difficult movement, often performed in ballet choreography. Understanding the postural sway during ballet turns is beneficial to both dancers and dance teachers alike.

Kinematic analysis of preterm newborns' spontaneous movements for postural activity assessment

open access: yesBiomedical Papers, 2015
Aims: The objectives of this pilot study were to assess the potential use of 3D videography for analyzing the motion of the body center of mass (COM) in newborns and to determine differences in spontaneous movements between preterm and full-term infants.

Defensive functions and potential ecological conflicts of floral stickiness

open access: yesScientific Reports, 2022
Stickiness of vegetative tissues has evolved multiple times in different plant families but is rare and understudied in flowers. While stickiness in general is thought to function primarily as a defense against herbivores, it may compromise mutualistic ...

ENGINEERING CONCEPTS IN ANALYSING LUMBOSACRAL LOAD IN POST-OPERATIVE SCOLIOTIC PATIENTS [PDF]

open access: yesJournal of Engineering Science and Technology, 2018
Lumbosacral alignment plays a major role in the mechanical low back pain in normal population. Malalignment causes increased strain to the muscles and ligaments around it which eventually leads to mechanical low back pain and discomfort.

Dynamic Measures of Balance during Obstacle-Crossing in Self-Selected Gait in Individuals with Mild-to-Moderate Parkinson’s Disease

open access: yesApplied Sciences
Individuals with Parkinson’s disease (PD) have postural instability and gait dysfunction that lead to falls and disability with disease progression. Increased fall risk is particularly seen during challenging gait tasks such as obstacle-crossing.

Locating the Center of Mass of Various Simplified Car Designs for the Problem of Flipping Over an Incline

open access: yesUndergraduate Journal of Mathematical Modeling: One + Two, 2020
The center of mass of a given system is referred to as a position that is the average of all of its components. I am given two cases in which I need to find the center of mass for the problem of flipping over an incline.

The Margin of Stability During a Single-Turn Pirouette in Female Amateur Dancers: A Pilot Study

open access: yesApplied Sciences
Balance control in pirouettes has previously been characterized by constraint of the topple angle. However, there is a paucity of research using the margin of stability (MoS) as a dynamic measure of balance related to pirouettes.

Analysis of the umbrella-type reflector opening process on a stand with an active gravity compensation system

open access: yesКосмические аппараты и технологии, 2021
During the verification of the functioning of the transformed structures in ground conditions, it is necessary to minimize the effect of gravity in order to exclude the occurrence of additional loads on the hinge assemblies and opening mechanisms.
