A trial to determine the effectiveness of sisal eaves-curtains impregnated with permethrin for malaria control was conducted in the malaria holoendemic western Kenya between 1991 and 1993. Indoor resting densities of Anopheles gambiae s.l. and Anopheles funestus were reduced by 90.9% and 93.8% respectively in protected houses. The entomological inoculation rate (EIR) was reduced by 72% in the i...

In Tanzania, the effect of sugar cane chewing on the development of caries was investigated. Two groups were selected; those who had easy access to sugar cane (sugar cane cutters) and those who did not (sisal plant workers). These groups had a similar socio-economic background, had similar levels of fluoride in drinking water, consumed similar amounts of refined sugar per day, but had a signifi...

In the last decades, researchers have developed new materials to improve the quality of human life. Owing to the frequent occurrence of bone fractures, it is important to develop plate materials for the fixation of fractured bones. These plate materials have to be lightweight, compatible with human tissues and ought to allow stiffness. Natural fibers have the advantage that they are renewable r...

It was evaluated the anthelmintic activity of Agave sisalana (sisal) juice against gastrointestinal nematodes and its potential toxic effects in goats. In vitro tests showed more than 95% reduction in larval counts of the genus Haemonchus spp. at concentrations between 86.5 and 146.3 mg.mL(-1). In vivo the percent reduction of larvae of the fourth (L4) and fifth (L5) stages of Haemonchus, Oesop...

The impact of the parallel programming model on scientiic computing is examined. A comparison is made between Sisal, a functional language with implicit parallelism, and SR, an imperative language with explicit parallelism. Both languages are modern, high-level, concurrent programming languages. Five diierent scientiic applications were programmed in each language, and evaluated for programmabi...

In this paper we introduce the uniqueness problem of array comprehensions. An array comprehension has the uniqueness property if it deenes each array element at most once. Uniqueness is a necessary condition for the correctness of single assignment languages such as Haskell, Id, and Sisal. The uniqueness problem can be stated as a data dependence problem, which in itself can be reformulated as ...

O presente estudo tem como objetivo apresentar o perfil epidemiológico de saúde bucal jovens adultos na faixa etária 15 a 19 anos, moradores dos municípios Barrocas e Conceição do coité, localizados no Território Sisal.

O objetivo foi estudar as ocorrências em que o grafema <d> é omitido, nas formas de gerúndio, cartas pessoais escritas por sertanejos baianos, pertencentes ao acervo “Cartas Sisal”, do projeto Corpus Eletrônico Documentos Históricos Sertão –CE-DOHS (CONSEPE 012/2020).

At the start of the 21st century annual world consumption of unwoven fabrics (for practical and technical uses) stood at 46 million tonnes, of which synthetics and cotton accounted for 49% and 42% respectively (with an upward trend in subsequent years), wool for 5%, and other fabrics 4% (linen, sisal, silk and others, with a downward trend) (Central Statistical Office Yearbooks – Roczniki GUS, ...

Abstract In this research, the hybrid natural fiber composite specimens were fabricated with a 64 wt% epoxy resin matrix, 20 coir fiber, and 16 of various fibers by hand-layup method. The influences (Coir, Jute, Flax, Cotton, Human Hair, Sisal, Kenaf, Calotropis) on mechanical characteristics (tensile, flexural, impact strengths) drilling properties (delamination factor ovality) Coir-fiber base...
