Introduction The regeneration of articular cartilage remains a challenge and is an unmet clinical need in orthopaedic surgery. Since hyaline articular cartilage will not heal spontaneously, these lesions eventually lead to degenerative joint disease. Cartilage abrasion, subchondral drilling, and microfracture techniques stimulate articular cartilage healing by introducing endogenous “stem cells...

the objective of this experiment was to investigate inheritance and gene action for resistance to sunn pest (eurygaster integriceps) and related traits in bread wheat including f1, f2 and backcross generations derived from a cross between line 15 as resistance and line 12 as susceptible parents. parents along with f1, f2, bc1 and bc2 generations were evaluated in a randomized complete block des...

Strong beautiful hair is universally desired across various cultures. Hence, the ways in which cleaning conditioning, grooming and styling processes affect the strength, feel and manageability of hair is of interest to beauty care science and technology. Human hair is a complex nanocomposite biological fiber. In this thesis, experiments are performed to better understand mechanical and electric...

Using high-speed videography, we investigated how fruit flies compensate for unilateral wing damage, in which loss of area on one wing compromises both weight support and roll torque equilibrium. Our results show that flies control for unilateral damage by rolling their body towards the damaged wing and by adjusting the kinematics of both the intact and damaged wings. To compensate for the redu...

The coupling motion of heave, pitch and roll of intact ship and damaged ship in waves, and the flow of flood water in damaged tank have been simulated based on viscous theory. The calculation model is a 29000 t tanker model moving at a constant speed with damaged tank in midship area. Three cosine waves including head waves, beam waves and oblique waves are simulated by boundary input method re...

The filamentous fungus Stachybotrys chartarum is known for its toxic metabolites and has been associated with serious health problems, including mycotoxicosis, among occupants of contaminated buildings. Here, we present results from a case study, where an ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method was developed for known and tentatively identified...
