chapatti is high consuming bread in the southeast countries of asia that in fresh form has a tender texture but within a few days of storage, becomes inflexible. in this research, the effects of guar and cmc gums at two levels of 0.25 and 0.5% on quality of chapatti bread were investigated. based on results, gum addition in different levels increased moisture and ash contends and improved rheol...

The basic hypothesis for the assessment of fire resistance of wood structures is that for temperatures above 300 oC, wood is no longer able to sustain any load. Consequently, the determination of the location of the 300 oC isotherm, the charring depth, is decisive for the result of fire resistance calculation methods. Charring rate of wood is dependent of numerous factors, such as wood species ...

The temperature and moisture regimes in a forest are key components in the forest ecosystem dynamics. Observations and studies indicate that the internal temperature distribution and moisture content of the tree influence not only growth and development, but onset and cessation of cambial activity[1], resistance to insect predation[2], and even affect the population dynamics of the insects[3]. ...

In the recent decades, water scarcity has become a major challenge for many reasons, especially the inadequate use of water resources. The mineral processing plant is among the most important water-consuming industries. Filtration, as one of the important processes in water recovery, is a process in which the solid-suspended particles are removed from the liquid. In the present work, the effect...

The objective of this paper is to present the contribution of a new dielectric constant characterisation for the modelling of radar backscattering behaviour. Our analysis is based on a large number of radar measurements acquired during different experimental campaigns (Orgeval'94, Pays de Caux'98, 99). We propose a dielectric constant model, based on the combination of contributions from both s...

Leaf water potential, leaf relative water content, and relative transpiration of barley were determined daily under greenhouse conditions at 3 growth stages: tillering to boot, boot to heading, and heading to maturity. The leaf moisture characteristic curve (relative water content versus leaf water potential) was the same for leaves of the same age growing in the same environment for the first ...

Upon an increase of moisture, unsaturated soil may collapse or swell, depending on the loading state and history. This important characteristic must be realistically reproduced by a constitutive model aimed for practical applications. In addition to collapse/swelling, other essential features, such as deformation and failure following arbitrary shearing paths, must also be realistically reprodu...
