Alkaliphilic Bacillus species and an alkaline active lipolytic enzyme

The Great Rift Valley running through Eastern Africa contains a large number of soda lakes. These unique lakes constitute among the most stable alkaline environments with a dense and varied population of microorganisms. Such microorganisms are invariable alkaliphiles and are considered to be a promising source of enzymes with unique features. Some enzymes produced by alkaliphilic microorganisms ha

Implementation of an OFDM Synchronization Algorithm

In this paper, a implementation of an OFDM synchronization algorithm is presented. Both time and frequency offsets are estimated simultaneously, using the cyclic prefix. The algorithm is implemented on a commercial DSP, an FPGA and as an ASIC. It is shown that although the algorithm is too complex to be implemented on a standard DSP, a hardware architecture that is optimized for the algorithm can

Clause-final subjects in English and Scandinavian

In English and in Scandinavian, presentational expletive constructions with clause-final subjects can be derived by moving the subject to a Spec position in the C-domain, and then raising the remainder of the clause across the subject to an even higher position. The discourse properties of the clause-final subjects then follow without further stipulations. Moreover, the view that the clause-final

No title

The aim of the present work is to describe the semantics and the discursive functions from a general cognitivist point of view of the usage of the Present Perfect in the spoken Spanish of Chile, Paraguay and Uruguay. It is argued that cross-linguistic values that prevailing theories often ascribe to perfect, such as continuity, current relevance and recency to the speech time –ST– do not offer a c
