The axe kick, in Olympic style taekwondo, has been identified as the most popular scoring technique aimed to the head during full contact competition. The first purpose of this study was to identify and investigate design issues with the current World Taekwondo Federation approved chest protector. A secondary purpose was to develop a novel chest protector addressing the identified design issues...

Crowdfunding has rapidly become a mainstream method used by individuals and groups to raise money for various projects and ventures. Increasingly, organizations that chiefly raise monies for charitable purposes have also been turning to crowdfunding as an additional funding source. Multiple higher-education institutions have done this by integrating crowdfunding as a staple of their fundraising...

wo new studies indicate that cycles of phosphorylation and dephosphorylation may be required during clathrin-mediated endocytosis. A newly identified kinase is responsible for the required phosphorylation. Clathrin and the adaptor protein 2 (AP2) complex are the major coat proteins of clathrin-coated vesicles (CCVs). Among components of the AP2 complex are ␣ and ␤ 2 adaptins, which mediate AP2 ...

ABSTRACT I examine the assumption that jets shape axisymmetrical morphological features of core-collapse supernova (CCSN) remnants are post-kick jets, i.e. neutron star (NS) launches these after explosion and it acquired its natal kick velocity. find this implies pre-collapse cores CCSN progenitors have sufficient angular momentum fluctuations to support jittering explode star. From finding sha...

For the first time, using Monte-Carlo calculations of the modern scenario for binary stellar evolution with account for spin evolution of magnetized compact stars (the “Scenario Machine”), we compute the amount of galactic binary pulsars with different companion types (OB-star, white dwarf (WD), neutron star (NS), black hole (BH), or planet) assuming various phenomenological distributions for k...

This paper presents Dempster-Shafer theory for move prediction in start kicking of the bicycle kick of sepak takraw game. Sepak takraw is a highly complex net-barrier kicking sport that involves dazzling displays of quick reflexes, acrobatic twists, turns and swerves of the agile human body movement. A Bicycle kick or Scissor kick is a physical move made by throwing the body up into the air, ma...

The breaststroke kick is responsible for a considerable portion of the forward propulsion in breaststroke swimming. The aim of this study was to measure selected anthropometric variables and functional properties of a swimmer's body: length of body parts; functional range of motion in the leg joints and anaerobic power of the lower limbs. Chosen kinematic variables useful in the evaluation of s...
