Abstract: A method of bonding includes applying a glass composition to at least a first material surface. The glass composition includes a glass powder and a solvent. The first material surface is disposed onto a second material surface. An elevated temperature is applied to the first material surface and the second material surface to form a bond between the first material surface and the second material surface. The first material surface and the second material surface are compressed under an isostatic pressure.

Abstract: A composition containing bark extract from the genus Pinus is described to improve, or prevent a decline in, human cognitive abilities or improve, or prevent symptoms of, neurological disorders in a human. The composition is advantageous for treatment where the human does not suffer from any kind of neurodegenerative disease at administration; the decline in cognitive abilities is age-associated, and is not associated with any neurodegenerative disease; or where the neurological disorders are associated with symptoms characterised by a loss in cognitive abilities.

Abstract: A method of assessing the cognitive aptitude of a subject to a predetermined task, the method including the steps of: (i) presenting to the subject a group of cognitive tasks; (ii) detecting brain response signals from the subject during presentation of the group of cognitive tasks; (iii) calculating SSVEP amplitude, phase and/or coherence responses from the brain response signals; and (iv) comparing the SSVEP responses to known SSVEP responses obtained from individuals with high and/or low aptitudes to the predetermined task in order to assess the subject's aptitude for the predetermined task.
