Polygonum cuspidatum water extract (PCWE) was shown to be a potent inhibitor of lipopolysaccharide (LPS)-induced expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). PCWE was compared to baicalin isolated from Scutellaria baicalensis Georgi and berberine of Coptidis rhizoma and Phellodendri cortex, for their effects on(More)
The pharmacological effects of Polygonum cuspidatum water extract (PCWE) on lipid biosynthesis were investigated in cultured human hepatocyte HepG2 cells. The addition of PCWE (5 and 20 microg/ml), which had no effect on cell proliferation and cellular protein content, caused a marked decrease in the cellular cholesterol content, particularly, the(More)
This paper addresses optimal architectural design using BIM at the design stage. We present a comparative study of the differences between datacentric and process-driven interoperability approaches during the design phases. The authors will elaborate on two approaches, summarize their consequences, and present a real application of the approach using a DAI(More)
To reduce the potential problems of window systems such as undesired heat gain (loss), glare, and thermal discomfort due to asymmetric radiation, double-skin systems have been introduced. The current problem with double skin systems is that their operation requires an adequate simulation model to realize optimal control of the system. The estimation of the(More)
This study compares three different control strategies for double-skin systems. The analyzed control strategies are (1) rule-based approach, (2) exhaustive search and (3) gradient-based search. The fundamental principle of the rule-based approach is “if this, do that” under certain circumstances, and the rules are generally based on expert knowledge. The(More)
Sensitivity analysis has been widely used for rational decision making of energy retrofit alternatives. A Sobol method is a variance based approach and provides powerful post-processing sensitivity results that enable to quantitatively identify influential and non-influential inputs. It can account for impacts of each input as well as impacts caused by all(More)
