Electrospinning is a unique way to producing novel polymer nano fibres with diameter typically in the range from 10 nm to 1500nm. Large length to diameter ratio and small mass to volume ratio of these nano-sizes fibres widens the areas of their application to many industrial uses. Nylon 6 nanofibres with diameter ranging from 150nm to 1300 nm were produced(More)
Modular synthesis of regiospecifically fluorinated 2,4-diene Weinreb amides, with defined stereochemistry at both double bonds, was achieved via two sequential Julia-Kocienski olefinations. In the first step, a Z-a-fluorovinyl Weinreb amide unit with a benzothiazolylsulfanyl substituent at the allylic position was assembled. This was achieved via(More)
Organ-specific characteristic of endothelial cells (ECs) is crucial for specific adhesion of cancer cells to ECs, which is a key factor in the formation of organ-specific metastasis. In this study, we developed a coculture of TMNK-1 (immortalized liver sinusoidal ECs) with 10T1/2 (resembling hepatic stellate cells) to augment organ-specific characteristic(More)
This paper presents the results of an exploratory empirical field test of the K-C Model of customer contact (Kellogg, 1991; Kellogg & Chase, 1995) in a hospital setting. Seventy service workers in seven departments of a regional hospital were surveyed regarding the elements of the K-C Model based on their perceptions of a "typical" service encounter with a(More)
The Session Initiation Protocol (SIP) is an application-layer protocol commonly used in VoIP for communication over the Internet. In this paper we describe a method to assess a particular kind of vulnerability of SIP implementation so that we could gain insights into its robustness. We used PROTOS as a tool to carry out exception element injection into SIP(More)
