The remarkable signal-detection capabilities of the auditory and vestibular systems have been studied for decades.Much of the conceptual framework that arose from this research has suggested that these sensory systems rest on the verge of instability, near a Hopf bifurcation, in order to explain the detection specifications.However, this paradigm c

Abstract Background People with brain or neural injuries, such as cerebral palsy or spinal cord injury, commonly have joint hyper-resistance.Diagnosis and treatment of joint hyper-resistance is challenging due to a mix of tonic and phasic contributions.The parallel-cascade (PC) system identification technique offers a potential solution to disentan

Aluminium sulphate is form by reacting alumina which contains in Derma Roller kaolin with sulphuric acid solution in a stirred reactor.Reaction occurs in variance of different time and temperature.The result of reaction is paste aluminium which will be extracted about 3 times using hot aquadest and consentration of aluminum analized by titrimetric
