Laser Induced Graphene by Multiple Lasing Toward

A simple and facile method for obtaining patterned graphene under ambient conditions on the surface of diverse materials ranging from renewable precursors such as food cloth paper and cardboard to high performance polymers like Kevlar or even on natural coal would be highly desirable Here we report a method of using multiple pulsed laser scribing to convert a wide range of substrates into

Autonomic Control of the Immediate Heart Rate Response to

Jan 01 1982· 1 The initial heart rate response to lying down was analysed in 18 younger 23–36 years and 10 older 48–67 years normal subjects and consisted of an immediate shortening of the R R interval reaching a maximum around the third or fourth beat after lying followed by a lengthening beyond the resting value to reach a steady level around beats 25–30

Renal Handling of Urate and Sodium Clinical Science

Jan 01 1997· 1 The renal effects of insulin may play a central role in the association between insulin resistance hypertension and hyperuricaemia After a 2 h baseline period we investigated the effects of exogenous insulin for 4 h 50 m units h−1 kg−1 on fractional renal sodium and urate excretion in 13 healthy subjects using the euglycaemic clamp and lithium clearance technique and performed a
