The dynamic viscoelasticity of bamboo kraft pulping black liquor under various temperatures (ranging from 50 to 80 °C) and solids concentrations (60 to 80 wt.%) was studied. Rotational rheometer analysis data indicated that the viscoelastic motion law with a high solids concentration in black liquor was in accordance with the Kelvin model, and black liquor with a medium concentration conformed ...

A variety of the Leucaena genus, Leucaena diversifolia, was used for pulp and paper making by kraft and refining processes and a OD(EP)DP bleaching sequence. The same species has been suggested as an energy crop and, in fact, this species used shows a high gross heating value; besides, this variety of Leucaena has appropriate characteristics for pulp and paper making. The holocellulose content ...

Samples of bleached kraft pine cellulosic pulp, either treated with an enzyme preparation (a Thermomyces lanuginosus xylanase, an Aspergillus sp. cellulase, and a multienzyme preparation NS-22086 containing both these activities) or untreated, were refined in a laboratory PFI mill. The treatment with cellulases contained in the last two preparations significantly improved the pulp's susceptibil...

1Corresponding author : Email : [email protected] Prostatitis represents the inflammatory process of the prostate gland. It is the most common urologic disorder occurring in older intact male dogs (Krawiec, 1994). Prostatitis may be acute or chronic in nature and is generally associated with prostatic infection (Kraft et al., 2008) either by ascending (from the urinary tract) or descendin...

Using Constraint Logic Programming and a data model approach, we provide an agent with a flexible way to plan and direct its actions and to manipulate and represent its knowledge. We use constraint solving techniques developed in the KRAFT project to provide the agent with a sophisticated reasoning and deliberation process. We explore the declarative use of constraints within a BDI Agent framew...

KRAFT is an agent architecture for the integration of heterogeneous information systems. The focus in KRAFT is on the integration of knowledge in the form of constraints. In this article we describe the architecture from an ontological perspective. We start by introducing the agent architecture and illustrate its application in the telecommunication-network design. We then describe how we asses...

We are entering an exciting time where millimeter-wave (MMW) systems are encroaching into everyday life, examples being communications, auto-navigation, and security. It is instinctive to consider these systems in industrial settings, as well. Given the current energy climate, it may be possible to apply MMW technology in an effort to improve efficiency in power generation industries. Paper is ...

We try to clarify the relations between quiver varieties of type A and Kraft-Procesi proof of normality of nilpotent conjugacy classes closures.
