The Role of Clinical Lumbo-Pelvic and Hip Tests in the Examination of Gait
… of the Trendelenburg Test, Single Leg Squat and Corkscrew Test as measures of dynamic stability of the Lumbo-Pelvic and Hip region in healthy participants and professional football players during gait. This was a laboratory based study using an experimental, repeated measures design. 18 full time …

Genetic analysis of hoof traits
… scores were.05,.12,.06,.14,.02 and.08 for corkscrew claw, heel erosion, interdigital dermatitis, laminitis, sole ulcers and white line separation. Severity of laminitis and sole ulcers peaked at four to five months postpartum approximately two months after peak milk yield. Heel erosion and …

Design of two-tailed swimmer to swim at low-Reynolds number
… at low Reynolds number, a three link swimmer, a corkscrew, or a flexible tail. Three devices utilizing the flexible-tail paradigm of swimming were tested using silicon oil to simulate a Reynolds number of approximately 0.6. Design parameters were uncovered which determine the successfulness of …

Simulating Sea Breeze Type Climatologies: Implications for Wind Energy, Weather Forecasting and Sailing in the Southern North Sea
… the generation of offshore calm zones, whilst corkscrew sea breezes can add to the wind resource through the formation of coastal jets. The lesser known corkscrew sea breeze is attributed to 70% of the total power contribution of all sea breeze events. As turbines increase both in size and …

The Effect of Dust in Small Bodies: A Sample of Jupiter Family Comets
… that northern pointing jet takes the shape of a corkscrew while the southern pointing is heavily influenced by solar radiation pressure. The azimuthally averaged dust radial profile slope of comet 45P/HMP gradually changes from -1.81+- 0.20 at 5.24 days pre-perihelion to -0.35 +- 0.16 at 74.41 …

Multi-body Dynamics Simulation and Analysis of Wave-adaptive Modular Vessels
… coupling effect that can lead to uncomfortable corkscrew motion under bow-quartering seas. A new class of catamaran called Wave-Adaptive Modular Vessels (WAM-V™) aims to help mitigate oceanic input from the cabin by allowing for the relative motion of components not common to classic catamaran …

Theoretical and experimental studies of energy transfer dynamics in collisions of atomic and molecular species with model organic surfaces
… motion, as well as a surprising propensity for "corkscrew" or "propeller" motion. The calculated stereodynamic trends suggest that the CH<sub>3</sub>-SAM is effectively more corrugated than the CF<sub>3</sub>-SAM. Finally, the feasibility for collisional-energy promoted, direct …

A detailed design analysis of a lumenally delivered, flexible, balloon-assisted, sterile endoscopic overtube.
… the end of a PTFE sheath. The second utilizes a corkscrew-shaped singular balloon crimped in the middle to form the dual expansion zones. Finally, the last prototype design uses a second outer sheath to encapsulate both balloons which provides the dilatory force to the tissue, and acts as a long …

Funktionelle Charakterisierung von Daughter of Sevenless
… (PI3Kinase) und der Corkscrew (Csw) Tyrosin Phosphatase wurden durch den Austausch des für die Bindung wichtigen Tyrosins gegen ein Phenylalanin mutiert. Die ektopische Expression der mutierten Konstrukte ohne Bindungsstellen für die Shc, PLCg und PI3Kinasen …

New methods for <i>in situ </i>measurement of mechanical root-reinforcement on slopes
… newly developed shear device was the ‘corkscrew’. Rotational installation of the screw ensured minimal soil and root disturbance. During vertical extraction the root-reinforced shear strength was mobilised along the interface of the soil plug caught within the screw. The measured …

Geometry and Hydrodynamics of Swimming with a Bundle of Bacterial Flagella
… On the other hand, bacteria are equipped with corkscrew-shaped flagella, which they can rotate rigidly in viscous fluids to generate forward motion. In this thesis, we consider the role played by the number of flagella in the swimming of multi-flagellated bacteria, for which the model organism …

Genotyping and antibiotic resistance of thermophilic Campylobacter isolates from Vietnam and Kenya
… microaerophilic growing, Gram-negative, curved corkscrew shaped and show motility. They colonize the intestine of many wild and domestic animals, particularly that of poultry. The review on Campylobacter shows specific aspects of Campylobacter/campylobacteriosis including: (i) taxonomy of the …

The little engine that could: Characterization of noncanonical components in the speed-variable flagellar motor of the symbiotic soil bacterium Sinorhizobium meliloti
The bacterial flagellum is a fascinating corkscrew-shaped macromolecular rotary machine used primarily to propel bacterial cells through their environment via the conversion of chemical potential energy into rotational power and thrust. Flagella are the principal targets of complex chemotaxis …
