    Notes: Purpose - This paper focuses on the project "Development of electronic components on circuit boards made of renewable resources" which has the aim of developing materials and technologies for the production of electronic components with printed wiring boards (PWB) completely made of renewable resources. Design/methodology/approach - Reviews the use of renewable resources in the electronics industry where there is potential for fostering sustainable development through its technological innovations. Findings - Outlines that ARBOFORM, a high-quality thermoplastic engineering material for applications that demand high technological standards, combines the positive properties of natural wood with the processing capabilities of thermoplastic materials. Originality/value - The motivation for the substitution of non-renewable raw materials is not only given by ecological aspects but could also be boosted in future as reserves of fossil resources are further depleted and costs increase.

    Notes: Summary New-born mice were X-rayed under extreme hypothermia in order to estimate the radioprotective effect of hypothermia on body weight, brain weight, development of cerebellum and the hematopoietic system. A protective effect was found in the rate of survival, in body and brain weight, in the cerebellum and in the number of erythrocytes. After hypothermia, the repair of damage in the cerebellum and the erythropoietic system starts earlier. The protected mature cerebellum shows an approximately normal status. Hypothermia does not prevent the initial decrease of lymphocytes caused by X-rays, and it produces a severe disturbance of hemoglobin content.

    Notes: Summary Mechanoreceptors of the hairy skin and the central pad of the cat's hind foot were activated using piezo-electric crystals as mechanical stimulators. Their afferent fibres were traced in the lumbar spinal cord by stimulating antidromically and by recording the collision of the antidromic and orthodromic action potentials. Low threshold mechanoreceptor units could be stimulated in isolation. It was possible, therefore, to follow the postspike excitability changes of their fibres in the spinal cord without interference from other spinal cord potentials. Primary afferent depolarization has been induced in cutaneous afferents by stimulating muscle and cutaneous nerves. It has been found that the a cutaneous fibres of mechanoreceptors were depolarized by volleys in a cutaneous fibres and to a lesser degree by volleys in Group I b, II and III muscle afferents but not by high threshold cutaneous afferents. The primary afferent depolarization of cutaneous fibres has been subjected to the action of an impulse propagating down that fibre to its central terminals. Excitability testing revealed that the amplitude and the time course of the primary afferent depolarization were only altered up to about 30 ms after the impulse indicating an active depolarization of the presynaptic terminals.

    Single unit responses and the total afferent outflow from the cat's foot pad upon mechanical stimulation (1968)

    Notes: Summary The properties of mechanosensitive units with large myelinated afferents were determined in the hairless skin of the central pad of the cat's hind foot, and the total afferent outflow from this region after short skin indentations and during constant force stimuli was measured in the plantar nerves. Basically three types of mechanosensitive units with afferent conduction velocities above 40 m/s were found: (a) receptors with the properties of Pacinian corpuscles (PC-receptors); (b) receptors which showed burst discharges for up to 500 ms after the onset of a constant force stimulus (RA-receptors); and (c) receptors which discharged throughout a constant force stimulus (SA-receptors). The afferent conduction velocities of these units were in the same range as those of receptors from the surrounding hairy skin. A considerable proportion of receptors from both skin areas had no collaterals in the dorsal columns. The afferent outflow after short skin indentations of up to 5 μ displacement consisted of impulses from PC-receptors only. Stimuli of 20 μ recruited between 50 and 100 afferent units of which less than 10% were other than PC-units. During constant force stimuli the afferent outflow came from SA-receptors only. Ten seconds after stimulus onset a 500 g stimulus evoked an afferent discharge of about 1000 imp/s and a 1000 g stimulus of about 1700 imp/s. At all times a power function of the form F=K · (S−S0)n related the afferent discharge F to the stimulus intensity S. The exponents were around n=0.5 and tended to increase in the course of the stimulus.

    Two specific feedback pathways to the central afferent terminals of phasic and tonic mechanoreceptors (1968)

    Notes: Summary In five types of mechanoreceptor afferents of the cat's hind foot, the primary afferent depolarization (PAD) induced by mechanical skin stimulation was measured by testing the excitability of their terminations in the dorsal horn. Two types of skin stimuli were used to set up activity in distinct populations of rapidly and slowly adapting mechanoreceptors respectively. The experiments revealed that two systems exist to generate PAD in cutaneous afferents, both being of negative feedback character. One system is activated by impulses from rapidly adapting low threshold receptors and preferentially depolarizes the terminals of such afferents, and correspondingly, the other system is activated by and operates on the slowly adapting units. In both PAD systems the size of the depolarization is graded depending on the stimulus strength. Further, the “tonic” system displays a “surround” pattern of organization similar to that of the “phasic” system which has already been described (Schmidt et al. 1967b). In the discussion the operational relationships of both systems and their functional implications are outlined.
