The conditional subjunction "äss" 'if' is used in many Swedish dialects. The article discusses its etymology and the connection between various phonetic variant as well as the process of its grammaticalization.

Latin poetry in the service of political propaganda. The poems commissioned by princes from hired writers of Latin verse had the same function as propagandist media and planted information has today. A survey from the Augustean times up till the 19th century.

A combinatorial complex multiplier has been designed for use in a pipelined fast Fourier transform processor. The performance in terms of throughput of the processor is limited by the multiplication. Therefore, the multiplier is optimized to make the input-to-output delay as short as possible. A new architecture based on distributed arithmetic, Wallace-trees, and carry-lookahead adders has been de

We have found necessary and sufficient conditions for the n-particle density to be N-representable for infinite A, if n is even. There are some mild restrictions on the one-density for these conditions to apply. The method is based on the Mercer expansion theorem. We suggest a simple method for total energy calculations based on this characterization also if the number of particles is finite. (c)

Abstract in UndeterminedThe dimeric CuA site found in cytochrome c oxidase and nitrous oxide reductase has been studied with the density functional B3LYP method. We have optimized the structure of the realistic (Im)(S(CH3)2)- Cu(SCH3)2Cu(Im)(CH3CONHCH3) model in the fully reduced, mixed-valence, and fully oxidized states. The optimized structures are very similar to crystal structures of the prote

Single channel currents were activated by GABA (0.5 to 5 microM) in cell-attached and inside-out patches from cells in the dentate gyrus of rat hippocampal slices. The currents reversed at the chloride equilibrium potential and were blocked by bicuculline (100 microM). Several different kinds of channel were seen: high conductance and low conductance, rectifying and "nonrectifying." Channels had m

The fate and effects of 2,4,6-trinitrotoluene (TNT) at marine ammunition dumping sites are essentially unknown. The objective of this study was to examine the release from solid TNT to seawater when covered by sediment of two different types (sandy and fine-grained) and thickness (0, 1 2, and 4 cm), under different temperatures (5, 10, and 20 degrees C), and light conditions (ambient daylight and

The structures of N-t-butyl-2-(diphenylphosphino)benzylammoniumchloride and N-t-butyl-2-(diphenylphosphino)benzylaminediacetatepalladium(II) have been determined by X-ray crystallography. The Pd-complex was prepared by treating palladiumdiacetate with N-t-butyl-2-(diphenylphosphino)benzylamine in CH2Cl2 for 4 h at room temperature. The organic compound crystallises in the monoclinic space group P2

A Saccharomyces cerevisiae screening strain was designed by combining multiple genetic modifications known to improve xylose utilization with the primary objective of enhancing xylose growth and fermentation in xylose isomerase (XI)-expressing strains. Strain TMB 3045 was obtained by expressing the XI gene from Thermus thermophilus in a strain in which the GRE3 gene coding for aldose reductase was

Serum samples from patients referred for liver biopsy for investigation of suspected chronic liver disease (n = 286) and from healthy middle-aged volunteers (n = 445) were analyzed for markers of exposure to GB virus C/hepatitis G virus (GBV-C/HGV), hepatitis B virus and hepatitis C virus. GBV-C/HGV analyses included GBV-C/HGV PCR for detection of viremia and GBV-C/HGV enzyme-linked immunosorbent

We present a model that explains the anomalous intensity ratios betweeneach of two very bright UV lines of Fe II at 2507 Å and 2509Å and its corresponding satellite line, observed in HST spectra ofa compact gaseous condensation (blob B) in the vicinity of the starprotect eta Car.The model is based on the assumption that the FeIItransitions have a substantial optical thickness, which varies as ares

Deregulation of the phosphatidylinositol 3-kinase (PI3K) pathway either through loss of PTEN or mutation of the catalytic subunit alpha of PI3K (PIK3CA) occurs frequently in human cancer. We identified PIK3CA mutations in 26% of 342 human breast tumor samples and cell lines at about equal frequency in tumor stages I to IV. To investigate the relationship between PTEN and PIK3CA, we generated a coh
