DNA encoding the signal peptide and the alpha 1-microglobulin part of the human alpha 1-microglobulin-bikunin gene was expressed in baculovirus-infected insect cells. Recombinant alpha 1-microglobulin was secreted and could be purified from the medium with a yield of 20-30 mg/ L. Biochemical and physicochemical characterization showed that the recombinant protein was very similar to alpha 1-microg

The gene for an IgA-binding protein from a group A streptococcal strain was cloned and expressed in Escherichia coli. The IgA-binding protein, called protein Arp, was purified on IgA-Sepharose, allowing complete purification in a single step. Analysis of protein Arp by Western immunoblotting demonstrated a major IgA-binding band, with an apparent molecular weight of 42 kD. The purified protein was

Early empirical studies in labour and urban economics addressing the role of commuting (on, e.g., wages and locational choice) have typically been confined to the use of survey data. Researchers are, however, increasingly getting access to large register databases with detailed information on where individuals live and work. A variety of methods have thus emerged to exploit the geocoded characteri

The adjoint (gluon) string tension in SU(2) lattice gauge theory has been found to be (8/3) times the corresponding fundamental (quark) string tension. This fact strongly favors the Lund-fragmentation-model prescription of treating hard gluons as kinks in the quark string.

An effective spin-dependent interaction Hamiltonian for low-lying gluon modes is calculated to O(±s) in the MIT bag model. We give expressions for the energy shifts of low-lying glueballs.

The use of diafiltration as part of ultrafiltration processes on an industrial scale is now the state-of-the-art in the food & beverage, biotech and pharma industry for the recovery of fermentation broth. In this paper the advantages and disadvantages of the most common process modes of diafiltration - batch and continuous - will be discussed. Further, the new concept of counter-current diafil

Relative rate techniques were used to study the title reactions in 930–1200 mbar of N2 diluent. The reaction rate coefficients measured in the present work are summarized by the expressions k(Cl + CH2F2) = 1.19 × 10−17 T2 exp(−1023/T) cm3 molecule−1 s−1 (253–553 K), k(Cl + CH3CCl3) = 2.41 × 10−12 exp(−1630/T) cm3 molecule−1 s−1 (253–313 K), and k(Cl + CF3CFH2) = 1.27 × 10−12 exp(−2019/T) cm3 molec

The evolution of compact groups of galaxies may represent one of the few places in the nearby universe in which massive galaxies are being forged through a complex set of processes involving tidal interaction, ram-pressure stripping, and perhaps finally "dry mergers" of galaxies stripped of their cool gas. Using collisionless N-body simulations, we propose a possible scenario for the formation of

We present an analytical model of the relation between the surface density of gas and star formation rate in galaxies and clouds, as a function of the presence of supersonic turbulence and the associated structure of the interstellar medium (ISM). The model predicts a power-law relation of index 3/2, flattened under the effects of stellar feedback at high densities or in very turbulent media, and

To evaluate if clinically usable estimates of physical performance and level of habitual physical activity are associated with fall risk in elderly men. A population-based sample of 3014 randomly selected men aged 69-80 years was recruited to medical centers in Gothenburg, Malmoe, or Uppsala. The level of physical activity and self-reported falls during the preceding 12 months was evaluated using

The term mission in its modern meaning was coined during the expansion of western Christianity which was in many ways entangled with colonialism. The western missionary movement’s modus operandi was adopted by missions from other backgrounds as well, when economic growth and growth of revivalist Christianity have coincided. When the outcome is new churches in economically underprivileged areas, th
