The twentieth century may be said to have been the century of ecumenism, a striving worldwide to realize church unity at different levels. It has frequently been asserted that one condition for reaching visible Church unity is that there should be basic agreement on baptism, eucharist and ministry. These three topics are dealt with in the Lima-document or BEM (1982). In the present study the sections of the latter that concern baptism are analyzed and also contextualized through a closer study of one of the responses to BEM, the official response of the Baptist Union of Sweden. This response gives a more traditional, closed Baptist opinion: baptism cannot be the basis of the church unity sought by BEM. The author shows here, however, that fundamental Baptist principles are being reconsidered, indicating considerable diversity within the Baptist Union concerning these questions. On the local level there are many ecumenical strivings, concretized in ecumenical congregations where different theologies and practices meet. This has opened up possibilities of church unity on the basis of both types of baptism (infant baptism and believers' baptism), and also membership on the basis of faith alone. By comparing official documents with public expressions of unofficial opinion, this study shows that the reality is more complex and ambiguous than is apparent in official documents. This book could be of interest because of its application of new methods to the study of "reception". To help an international readership, a historical presentation of the Baptist Union of Sweden introduces this study.

This book covers the new topic of GPU computing with many applications involved, taken from diverse fields such as networking, seismology, fluid mechanics, nano-materials, data-mining , earthquakes ,mantle convection, visualization. It will show the public why GPU computing is important and easy to use. It will offer a reason why GPU computing is useful and how to implement codes in an everyday situation.

It is now 30 years since the network for digital communication, the ARPA-net, first came into operation. Since the first experiments with sending electronic mail and performing file transfers, the development of networks has been truly remarkable. Today's Internet continues to develop at an exponential rate that even surpasses that of computing and storage technologies. About five years after being commercialized, it has become as pervasive as the tele phone had become 30 years after its initial deployment. In the United States, the size of the Internet industry already exceeds that of the auto industry, which has been in existence for about 100 years. The exponentially increas ing capabilities of communication, computing, and storage systems is also reshaping the way science and engineering are pursued. Large-scale simulation studies in chemistry, physics, engineering, and sev eral other disciplines may now produce data sets of ,several terabytes or petabytes. Similarly, almost all measurements today produce data in digital form, whether from collections of sensors, three-dimensional digital images, or video. These data sets often represent complex phenomena that require rich visualization capabilities and efficient data-mining techniques to under stand. Furthermore, the data may be produced and archived in several differ ent locations, and the analysis carried out by teams with members at several locations-possibly distinct from those with significant storage, computation, or visualization facilities. The emerging computational Grids enable the transparent use of remote instruments, computational and data resources.
