BACKGROUND/AIMS The potential of a new encapsulation system has been evaluated as an artificial housing for liver cells. METHODS Murine hepatocytes were encapsulated in specially designed multicomponent capsules formed by polyelectrolyte complexation of sodium alginate, cellulose sulphate and poly(methylene-co-guanidine) hydrochloride, the permeability of(More)
A new generation of microcapsules based on the use of oligomers which participate in polyelectrolyte complexation reactions has been developed. These freeze-thaw stable capsules have been applied as a bioartificial pancreas and have resulted in normoglycemia for periods of six months in concordant xenotransplantations. The new chemistry permits the control(More)
This paper presents a model for information technology (IT) sustainability within government organizations in developing countries. Previous studies indicate that most government IT implementations in developing countries fail to be sustained and to achieve their implementation goals. The causes of sustainability failure include technology, economics and(More)
This paper describes research in progress to explore the role of culture in adoption of e-government at local government levels. The majority of research in electronic government highlighted cultural issues but they do not identify specific cultural traits influencing e-government adoption and use. From our literature review we identified four major(More)
Researches in electronic government have indicated a number of organizational barriers that hinder the adoption and implementation of electronic government. This paper proposes a research framework for analysing how organizational barriers influence the adoption and implementation of e-government at local levels. The framework is constructed based on four(More)
In the whole animal, metabolic regulations are set by reciprocal interactions between various organs, via the blood circulation. At present, analyses of such interactions require numerous and uneasily controlled in vivo experiments. In a search for an alternative to in vivo experiments, our work aims at developing a coculture system in which different cell(More)
This paper describes the status of local e-government in Indonesia using the United Nations e-government benchmarking model. Using data from the Indonesia Ministry of Internal Affairs, we examined 353 local government websites from early March to the end of May 2011. The results show that the majority of local government websites (193) are still at the(More)
Adoption and implementation of e-government within local government organizations are influenced by many external factors. These factors are often perceived as forces or pressures that influence local government decisions to adopt and implement the initiatives. This study uses the concept of coercive force from institutional theory to explain those external(More)
