Dexterous hands

Neurobehavioral examinations are useful for identifying neurotoxicant-mediated deficits, but it is often difficult to localize the site of toxic action from such tests. For example, sensorimotor tests of reaction time, manual dexterity, hand-eye coordination, and finger tapping can indicate either neuromuscular or psychomotor damage. 

The purpose of this book is to present computationally efficient algorithms for the dynamic simulation of closed-chain robotic systems. In particular, the simulation of single closed chains and simple closed-chain mechanisms (such as multilegged vehicles or dexterous hands) is investi ted in detail. In conjunction with the simulation algorithms, efficient algorithms are also derived for the computation of the joint space and operational space inntia matrices of a manipulator. These two inertial quantities are important factors in a variety of robotics applications, including both simulation and control.

In one case study, anorexia was reported in a man who washed his hands with diesel fuel over several weeks (Crisp et al. 1979). Effects resulting from inhalation versus dermal exposure could not be distinguished in this case. An epidemiological study found a significant increase in neurasthenia (i.e., fatigue, depressed mood, lack of initiative, dizziness, and sleep disturbances) in workers who were chronically exposed to jet fuels by either inhalation, oral, and/or dermal exposure (Knave et al. 1978). Also, attention and sensorimotor speed were impaired in the exposed workers, but no effects were found on memory function or manual dexterity. Results of EEG tests suggest that the exposed workers may have instability in the thalamocortical system. The limitations of the study were discussed in detail in Section 2.2.1.2 under Respiratory Effects. 

A number of effects have been associated with chronic exposure to jet fuel in factory workers (Knave et al. 1978). These effects included increases in the occurrence of neurasthenia (anxiety and/or mental depression, fatigue, depressed mood, lack of initiative, dizziness, palpitations, thoracic oppression, sleep disturbances) and eye irritation. Psychological tests found that attention and sensorimotor speed were impaired in exposed workers, but there were no effects on memory functions or manual dexterity. EEG tests suggested that there may have been instability in the thalamocortical system in the exposed group. However, the type of jet fuels were not noted nor was there a control for exposure to other compounds. Inhalation exposure is likely since jet fuel vapor was detected by the study authors however, dermal and oral (i.e., eating with contaminated hands) exposures may also be possible. 

The bailer, who prepares the mass for the thrower, is shown at D. Each piece is weighed when the vessels require to be of a uniform size, a stroke or two of tho hand being given before it is pressed into the balls, r ready for use by the thrower, who, after the formation of the vessel, dexterously separates it at tho base from tho disc by a fine brass wire, and places it on a board, where t remains until the moss becomes sufficiently firm to bear without injury the subsequent processes of turning, handling, et cetera. 

Twitch The drag causes the user s body to move and jerk uncontrollably. The user experiences violent tremors in his face, body, and hands for the side effect s duration, incurring a -2 penalty on Dexterity and Charisma-based checks until the effect subsides.
