We show that the problem of constructing a minimum directed Steiner tree of depth O(log(d)n) in a directed graph of maximum outdegree d admits an expO(root logn)-approximation in polynomial time.
This study investigates the relationship between the understanding of Jesus as the only teacher and the transmission of the Jesus tradition in the community behind the Gospel of Matthew.
Popular Abstract in English Modern society is still largely based on fossil resources. However, there are growing concerns about the security and cost of these resources, as well as climate change resulting from the combustion of fossil fuels. Biofuels represent renewable fuels with the potential to mitigate the adverse effects of fossil fuels, providing a more sustainable alternative. The transpBioethanol from sugarcane is a sustainable alternative to fossil fuels, and the increasing demand for fuel ethanol has prompted studies on the use of the lignocellulosic residues of sugarcane, namely bagasse and leaves, as new feedstock. This thesis describes various process designs and the economic feasibility of producing second generation (2G) ethanol from bagasse and leaves via the enzymatic r
In this article career as metaphor and various career models are the object of a critical review. The question at issue is whether career as mataphor helps us understand the social dynamics that characterize substance abuse? Different models such as the stepping-stone and gateway hypothesis and H S Beckers career model is scrutinized. It is pointed out that these career models are one-sided and h

This paper focuses on the performance analysis of general charge sampling circuits that have been applied in signal capture. The theoretical analysis applies not only for small signal capture, but also for normal signal sampling. Based on a general charge sampling model, the transferring function, together with noise transference, clock jitter tolerance, and clock feedthrough effects, are analysed
A discussion session where the conference participants are invited to participate is planned. One topic for the session is to discuss experiences of multidisciplinary research on integration of human factors and different production concepts applied in change processes within Swedish companies. An important question that the discussion will focus on is: How to get high quality in multidisciplinary
