Two high-performance bacterial cellulose (BC) nanofiber-based hybrid structures were produced using an in situ self-assembly approach, one with microfibrillated cellulose (MFC) and another with sisal fiber, by incorporating them in the fermentation media. The fabricated BC-MFC hybrid and BC-sisal hybrid fibers showed enhanced mechanical properties compared to pure BC and sisal fibers, respectiv...

Agave sisalana (sisal) is known worldwide as a source of hard fibers, and Brazil is the largest producer of sisal. Nonetheless, the process of removing the fibers of the sisal leaf generates 95% waste. In this study, we applied chemical sequential steps (hydrothermal extraction, precipitation, liquid-liquid extraction, crystallization, SiO2 and Sephadex LH 20 column chromatography) to obtain pe...

We formally describe optimization techniques for the comm pilation of the language Sisal 2.0. More precisely, we translate Sisal programs into data-ow IF1 graphs and optimize these graphs. An inn teractive visualization environment for IF1 graphs is also provided.

Submitted: May 21, 2013; Accepted: Jul 3, 2013; Published: Jul 20, 2013 Abstract: Mushrooms are a primary part of managing solid waste, building organic soil and returning minerals to the soil. Sisal processing in Kenya generates an estimated 611,875 tonnes of solid waste annually, which is discarded leading to environmental pollution. Sisal waste contains; lignin, cellulose and hemicelluloses ...

Recent years have seen an increase in the use of lignocellulosic materials in the development of bioproducts. Because sisal fiber is a low cost raw material and is readily available, this work aimed to evaluate its hemicellulose fraction for the simultaneous production of xylitol and ethanol. The sisal fiber presented a higher hemicellulose content than other frequently-employed biomasses, such...

Sisal leaves which constitute only 2% of the sisal plant have been used in the production of pulp and fiber; the remaining 98% which is mostly of the sisal bole is largely regarded as waste. The bole’s high inulin fraction (2436%) is of particular significance due to its chemical functionality and relative ease of fermentation. utilisationThe objective of this study was to identify properties a...

This paper describes an improvement of the reusability model of the SISAL language. The study of the object oriented paradigm limits leads us to propose several extensions promoting a higher reusability scheme. The paper contains the description of the FOL language and of its translator to SISAL as well as insights in our future work on impure eeects.

In this paper we present the results of the implementation of D-OSC: a prototype SISAL compiler for distributed-memory machines. The compiler is an extension of the Optimizing SISAL Compiler (OSC) version 12.9.1, it generates C code with calls to the message passing library MPI. The main goals of this implementation are to obtain a SISAL compiler that generates code for distributed-memory machi...

Fiber reinforcement is widely used in construction engineering to improve the mechanical properties of soil because it increases the soil's strength and improves the soil's mechanical properties. However, the mechanical properties of fiber-reinforced soils remain controversial. The present study investigated the mechanical properties of silty clay reinforced with discrete, randomly distributed ...
