Lung function in sisal ropemakers.

Histamine-releasing activity and bronchoconstricting effects of sisal.

Nicholls, P. J., Evans, E., Valic', F., and ;uskin, E. (1973). British Journal of Industrial Medicine, 30, 142-145. Histamine-releasing activity and bronchoconstricting effects of sisal. Extracts of dry and oiled sisal released histamine from pig and human but not from rat lung tissue. A suspension in Tyrode solution of the oil used for softening the sisal fibres had a pH of 8-1 and also releas...

Byssinosis, respiratory symptoms and spirometric lung function tests in Tanzanian sisal workers.

A Formal Semantics and an Interactive Environment for Sisal

We present a formal deenition of the dynamic semantics of a signiicant part of the language Sisal 2.0 in the structural operational style of Natural Semantics, using Ty-pol inference rules within the Centaur system, a generic speciication environment. Sisal is a strongly typed, applicative, single assignment language in use on a variety of parallel processors, including conventional multiproces...

Implicit Array Copying : Prevention is Better than

SISAL is a purely functional language which supports arrays. The diiculty with supporting purely functional arrays is that a prohibitive amount of copying can be necessary. SISAL uses a sophisticated compile-time analysis to alleviate some copying associated with array operations. This compile-time analysis is discussed and some problems with it are exposed. The alternative to curing copying, i...

High prevalence of immunoglobulin E (IgE) sensitization among sisal (Agave sisalana) processing workers in Tanzania.

PURPOSE Allergic sensitization among workers exposed to sisal is scarcely documented. We examined whether sisal processing is associated with IgE sensitization and its relationship to the prevalence of respiratory symptoms among Tanzanian processors. METHODS 138 sisal exposed workers and 78 non-exposed controls were skin prick tested (SPT) using dry sisal extract and fresh sisal sap. Sera fro...
