Studies on the Ring Opening Polymerisation of Cyclopentene
… showed that trans-polypentenamer was formed. A kinetic chain mechanism was invoked to describe the propagation step in the polymerisation and to account for the bimodal molecular weight distribution of the polymer it was proposed that two active propagating species were present in the …

Comparing Shoulder Manual Muscle Testing With Scapular Retraction And Core Activation
<p>The kinetic chain plays a large role in the force production of the body during activity. The core and the scapula are critical kinetic chain links to the upper extremity during overhead motions and should likely be accounted for when performing manual muscle testing of the shoulder. The purpose …

Revealing complexities within flat-water kayaking: injury prevention and biomechanical analysis
… corrective pre-habilitation programme of the kinetic chain, conducted twice a week for 10 weeks, would reduce these predisposing factors. A group of 19 marathon paddlers were assessed before and after the intervention, with nine of them receiving the intervention. The 10-week intervention …

Ankle Mobility and Lower Extremity Functional Stability Assessment and Intervention for Collegiate Baseball Pitchers
… with impaired force transfer through the kinetic chain. Limited ankle dorsiflexion may alter stride length and increase injury risk. Purpose: This study aimed to establish a screening tool to identify drive leg ankle imbalances in collegiate pitchers and examine the effects of a targeted …

Hydrocarbon Functionalization via a New Free Radical-Based Condensation Reaction
A new free radical chain process for the allylation of hydrocarbons and some other substrates utilizing substituted allyl bromides (R-H + C=C-C-Br -> R-C-C=C + HBr) has been developed. Good to excellent yields were observed in all cases. Kinetic chain measurements and competition experiments were …

The Ring-opening Polymerisations of Cyclic Olefins
… the molar ratio of the catalyst components. The kinetics of the polymerisation reaction were considered and a series of reactions were proposed in which two tungsten complexes were formed which then combined with the aluminium compound to form two active species. A kinetic chain scheme was …

Effectiveness of a Shoulder Strengthening Intervention on the Incidence Rate of Glenohumeral Joint Instability Injuries
… <br /><strong>Intervention:</strong> The closed kinetic chain upper extremity stability test (CKCUEST) was used to identify subjects at risk for glenohumeral joint instability injuries. A shoulderstrengthening program was implemented into the summer workout program before the 2015 college …

Hip-shoulder separation in the javelin throw and its relationship with level of experience
… sport and is excellent example of how the kinetic chain works starting with the landing of the drive foot (right foot) causing a chain reaction traveling up the knee to the hip, through the trunk, to the shoulder, the elbow, and then the wrist. The purpose of this study was to investigate …

Radical additions of hydrocarbons, ethers and acetals to alkenes via allyl transfer reaction: A new chain reaction for C-H bond functionalization
… alkyl aromatic hydrocarbons is demonstrated. Kinetic studies were performed to observe the efficiency of the new chain reaction compared to the previously reported studies with allyl-bromides. We recently discovered that these allyl substrates are useful for the functionalization of ethers and …

Control of Network Topology in Photopolymer Networks for Additive Manufacturing
… polymerization via addition-fragmentation chain transfer (AFCT) and reversible addition-fragmentation chain transfer (RAFT), and their applications in photopolymer networks to improve material properties and introduce novel functional materials to additive manufacturing. Chapter 2. In this …

Performance and Injury Predictability during Firefighter Candidate Training
The purpose of this study was to determine if a firefighter's fundamental movement patterns can act as predictors for occupational injury and performance during the firefighter academy training. The study consisted of 23 firefighter candidates entering the 16-week firefighter academy training. The …

Kinematic coupling between the foot and lower limb during gait
… to plantarflex and abduct. This implies that a kinetic chain exists with proximal segments driving motion of the distal segments during propulsion. IMPLICATIONS: If the proximal segments drive the motion of the foot then injuries associated with excessive or prolonged pronation should not only …
