Whole cells of alkaliphilic Bacillus pseudofirmus AR-199, induced for beta-galactosidase activity, were used for the synthesis of 1-hexyl-beta-D-galactoside and 1-octyl-beta-D-galactoside, respectively, by transglycosylation reaction between lactose and the corresponding alcohol acceptor. The product yield was strongly influenced by the initial water content in the reaction mixture. Water content
The sequence of peaks and troughs in a load process acting on a material, contains important information about the damage caused by the load, e.g. on the growth rate of a widening crack. The stress range, i.e. the difference between a peak and the following trough, is one of the variables that is used to describe e.g. fatigue life under random loading. The moments, in particular the mean and varia
The molar mass and theological properties of an exopolysaccharide (EPS) from Pediococcus damnosus 2.6 were investigated. The molar mass was determined by asymmetrical flow field-flow fractionation coupled with multiangle light scattering and refractive index detection. The EPS was observed to be a flexible chain polymer with a molar mass value of 4 x 10(6) g mol(-1). Heating the sample at 80 degre
A rheological study of mixed micelles formed by PEO-PPO-PEO triblock copolymer P123 and nonionic surfactant C12EO6 in aqueous solutions has been carried out with the purpose of investigating the time dependence of a shape transition of the mixed micelles and characterizing the shape before and after the transition. The rheology results presented in this report give clear evidence that the P123-C12
PURPOSE: To evaluate the effect of intraocular pressure (IOP)-reducing treatment on the development of disc hemorrhages in patients with glaucoma. DESIGN: Prospective cohort study of patients in the Early Manifest Glaucoma Trial, followed up to 11 years (median = 8 years). PARTICIPANTS: Patients with newly detected glaucoma randomized to argon laser trabeculoplasty plus betaxolol (n = 129) or no i
A method based on three-phase hollow fiber liquid phase microextraction was developed and successfully applied to aerosols for the analysis of lignin pyrolysis acids such as syringic acid, vanillic acid and p-salicylic acid. Important parameters related to extraction process like organic solvent for membrane phase, tri-n-octylphosphine (TOPO) oxide contents in organic solvent, stirring speed, extr
The BGO Rugby Ball is a large solid angle electromagnetic calorimeter now installed in the ELSA Facility in Bonn. The BGO is operating in the BGO-OD experiment aiming to study meson photoproduction off proton and neutron induced by a Bremsstrahlung polarized gamma beam of energies from 0.2 to 3.2 GeV and an intensity of 5 × 107 photons per second. The scintillating material characteristics and the
Occupational balance promotes health, knowledge about occupational balance among older workers is important. This qualitative study aimed to describe occupational balance among older workers in Sweden. Six focus groups and two individual interviews were conducted with 26 workers, aged 65 years and older. The findings showed that drawing on abilities and resources, a harmonious mix of occupations,
Dark matter direct detection experiments need to know the local phase space density of dark matter fdm(r,v,t) in order to derive dark matter particle properties. To date, calculations for fdm(r,v,t) have been based on simulations that model the dark matter alone. Here we include the influence of the baryonic matter. We find that a star/gas disc at high redshift (z∼1) causes merging satellites to b
Fetal mesencephalic mouse tissue, rich in dopamine neurons, was xenografted as a dissociated cell suspension into the striatum of rats with unilateral 6-hydroxydopamine induced lesions of the mesostriatal pathway. The rats were either assigned to a 10-day, 21-day or 42-day Cyclosporin A (CyA) immunosuppression scheme, or given no immunosuppression. The functional effects of the grafts were followe
An eight-channel, 1 ns bin-size, 23 b dynamic range, single-chip, multihit, time-to-digital converter (TDC) is presented in this paper. A new architecture mixing two previous TDC realizations has been adopted. The chip can execute common-start or common-stop operations on the trailing, leading, or both transitions of the input channels; it stores at least 32 events/channel with a double-hit resolu
