The structure of lignins isolated from the herbaceous plants sisal ( Agave sisalana), kenaf ( Hibiscus cannabinus), abaca ( Musa textilis) and curaua ( Ananas erectifolius) has been studied upon spectroscopic (2D-NMR) and chemical degradative (derivatization followed by reductive cleavage) methods. The analyses demonstrate that the structure of the lignins from these plants is highly remarkable...

To improve the interfacial bonding of sisal fiber-reinforced polylactide biocomposites, polylactide (PLA) and sisal fibers (SF) were melt-blended to fabricate bio-based composites via in situ reactive interfacial compatibilization with addition of a commercial grade epoxy-functionalized oligomer Joncryl ADR@-4368 (ADR). The FTIR (Fourier Transform infrared spectroscopy) analysis and SEM (scanni...

This paper describes a prototype Sisal compiler that supports distributed-as well as shared-memory machines. The compiler, fsc, modiies the code-generation phase of the optimizing Sisal compiler, osc, to use the Filaments library as a run-time system. Filaments eeciently supports ne-grain parallelism and a shared-memory programming model. Using ne-grain threads makes it possible to implement re...

To improve the interfacial bonding of sisal fiber reinforced polylactide biocomposites, polylactide (PLA) and sisal fibers (SF) were melt-blended to fabricate bio-based composites via in situ reactive interfacial compatibilization with the addition of an epoxy-functionalized oligomer (ADR). The FTIR analysis and SEM characterization demonstrated that PLA molecular chain was bonded to the fiber ...

Sisal purple leafroll disease (SPLD) is a destructive affecting sisal in China, however, its etiology remains unknown. This characterized by margins and rolling yellowing of the leaves. Recently, phytoplasma was found to be present SPLD-affected according PCR assay. To further verify presence phytoplasma, determine association with SPLD identify possible pathogenic infecting sisal, 80 sym...

The difficulty of programming parallel computers has impeded their wide-spread use. The problems are caused by existing hardware and software tools. The software problems on shared-memory and vector computers can be solved by using deterministic high-performance functional languages like SISAL. Distributed-memory computers have even more obstacles than shared-memory parallel machines. Research ...

Saponins, molecules classified as triterpenic or steroidal glycosides, are metabolites distributed in all the plant kingdom that can be used for the production of foods, cosmetics, and pharmaceuticals, as well as in soil bioremediation. Saponins are normally extracted from natural resources with water, ethanol and/or methanol, and then concentrated by liquid-liquid partitioning with n-butanol. ...

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...
