The identification of bast fibre samples, in particular, bast fibres used in textiles, is an important issue in archaeology, criminology and other scientific fields. One of the characteristic features of bast fibres is their fibrillar orientation, referred to as Z- or S twist (or alternatively right- and left-handed fibres). An empirical test for determining the fibrillar orientation using pola...

The automatic generation of image captions has received considerable attention. The problem of evaluating caption generation systems, though, has not been that much explored. We propose a novel evaluation approach based on comparing the underlying visual semantics of the candidate and ground-truth captions. With this goal in mind we have defined a semantic representation for visually descriptiv...

Crotalaria juncea bast fibers a novel cellulose rich material is valorized by producing nanocrystals (CNCs) which gained much attention due to its unique properties. CNCs obtained during this study consisted of two steps: pretreatment C. obtain chemically purified followed sulfuric acid hydrolysis. Efficacy different methods chlor-alkali method (pre-treatment-I) and ultra sound assisted chlorin...

In this paper, we present Bast, an extensible library of protocol classes. The latter is aimed at helping system programmers to build distributed programming environments. Protocol classes constitute the basic structuring components for higher-level programming models, such as the transactional model, and add exibility to distributed environments. We focus on classes that implement a generic ag...

the present research has been conducted to investigate the soda and soda-anthraquiuone pulping from whole kenaf (v36). in this respect, anatomical characteristics of kenaf bast and core fibers as well as the soda and soda-aq pulp properties produced at four sodium hydroxide concentrations, namely 25, 30, 35 and 40 (g/lit), have been evaluated. the pulping results indicated that pulp yield and k...

The precise identification of hemp (Cannabis sativa L.) fiber in ancient papers is great significance the study paper history. However, different species phloem fibers belonging to bast (e.g., hemp, ramie, flax, jute) used traditional hand papermaking East Asian region present similar microscopic morphological traits, which renders their accurate problematic and may cause controversy archaeolog...

Traffic is the main source responsible for unacceptable exposure in densely populated communities. The first round of noise mapping and action planning according to 2002/49/EC yielded results with differences hard to be interpreted as real image of the noise climate in the MS. Based on a study financed by the German BAST (Federal Highway Research Institute), the influence of input data, calcula...

The use of atomization or an aerosol formation is investigated as a vehicle for enzyme treatment of dew-retted flax fibers. A cellulase/endoglucanase from Trichoderma reesei is applied by atomization to dew-retted fibers at concentrations of 0. 50, and 100 U. Enzyme activity post-atomization is verified by GLC analyses of sugars hydrolyzed from the treated fibers. Cellulase treatment results in...
