objective(s):investigation of phase diagram of various drug formulations is effective to predict different phase region of drugs to detect final formula. the purpose of this research was to develop the ternary phase diagrams for a drug microemulsion system consisting of cucurbita pepo (pumpkin) oil, surfactant (tween 80) and deionized water. materials and methods:an electrical conductivity was ...

application of supramolecular polymer blending in preparation of materialswith adjustable mechanical properties is addressed. it is anticipated that the microstructure and properties of polymer blends are drastically controlled by the inter-molecular interactions. on this basis, the effect of strongly dimerising ureidopyrimidinone end groups (upy) with the capability of quadruple hydrogen bondi...

knowledge of the probable origin and behaviour of arsenic certainly gives valuable insights into the potential for transfer in the environment and of the risks involved in mining sites. sequential extraction analyses are common experiments often used to study the origin and behaviour of potentially toxic elements. the method, however, presents some deficiencies, including labor-intensive proced...

This paper will present the main topics of our team. The IVGI Team (French acronym for Virtual Engineering for Industrial Engineering) defines methods for the integration of several models in the system-design process. The focus is on the integration of cost factors and human factors based on a FBS-PPR model designed to capture enterprise knowledge. For these fields, cost, human and knowledge, ...

There are some records of early attempts to maintain BF Trypanosoma brucei in vitro [1, 2], but short-term propagation, in the presence of feeder cells (L-cells), was not achieved until 1967 [3]. Continuous propagation was not reported until 1977, when the Lister 427 strain (clone 052 from GAMC) was successfully propagated in RPMI 1640 medium with 25 mM HEPES and 20% heatinactivated FBS, in the...

This paper presents a framework for a computational model of temporary design teams (TDTs). The framework is based on the situated Function-Behaviour-Structure (FBS) ontology, which is used to describe the different aspects of a TDT. This paper demonstrates how TDTs can be represented and reasoned about in terms of the FBS variables. A situated social agent’s architecture is introduced. At the ...

This paper describes the proposed Differentiated Services schemes, makes comparison between proposals, and matches them against the proposed Differentiated Services (DS) byte and the DS architecture proposed by the Differentiated Services Working Group (DSWG). In addition an application feedback is introduced as a new DS service. This method enables applications to prioritize packets within an ...

This paper presents a new set of forwarding behaviors that fits rate-adaptive and delay-sensitive applications with limited loss tolerance. We consider an application to have limited loss tolerance if it needs loss-free forwarding of specific packets up to a certain rate. The new set of forwarding behaviors are attractive for developing real-time applications for the Internet. In particular, su...

This paper presents a view of design methods as process artefacts that can be represented using the function-behaviour-structure (FBS) ontology. This view allows identifying five fundamental approaches to methods: black-box, procedural, artefact-centric, formal and managerial approaches. They all describe method structure but emphasise different aspects of it. Capturing these differences addres...

Experimental observations have put in evidence autonomous self-sustained circadian oscillators in most mammalian cells, and proved the existence of molecular links between the circadian clock and the cell cycle. Several models have been elaborated to assess conditions of control of the cell cycle by the circadian clock, in particular through the regulation by clock genes of Wee1, an inhibitor o...
