High-solids enzymatic hydrolysis of steam-exploded willow without prior water washing

A laboratory reactor equipped with a screw press was used for the hydrolysis of steam-SO2-exploded willow Salix caprea by a composition of Trichodemma reesei and Aspergillusfoetidus enzyme preparations at high substrate concentration. Optimal conditions providing the maximal volume of hydrolysis syrup with maximal sugar concentrations were determined. Two different hydrolysis procedures were devel

Can severe language disorders be identified before age 3;6?

A new classification system indicating type and severity of language disorder was applied by five speech pathologists. They independently interpreted information from the initial language assessment of 39 children with developmental language disorder (DLD), who had been assessed by one of the present authors before age 3;6. Information about planned intervention was also collected. The children we

Cytokine Regulation of Hematopoietic Stem Cells and Lymphopoiesis

Large numbers of blood cells need to be continuously replaced in order to sustain the crucial functions of the immune system, oxygen transport and blood clotting. The large diversity of cell types required to maintain the integrity of the blood system are all produced from blood forming or hematopoietic stem cells (HSCs). HSCs have the unique property of self renewal, ensuring life-long replenishm

Inclusive dijet production at low Bjorken-x in deep inelastic scattering

Dijet production in deep inelastic ep scattering is investigated in the region of low values of the Bjorken-variable x (10(-4) < x < 10(-2)) and low photon virtualities Q(2) (5 < Q(2) < 100 GeV2). The measured dijet cross sections are compared with perturbative QCD calculations in next-to-leading order. For most dijet variables studied, these calculations can provide a reasonable description of th

Production Control of a Pulp and Paper Mill

A summary of a study devoted to computerized scheduling of a complex integrated pulp and paper mill is presented. A mathematical model of the mill was built and the scheduling problem was formulated as an optimal control problem for a multivariable deterministic system. The mill is described by a linear, first-order, vectorvalued differential equation. The control system consists of 10 state varia

Quantification of insulin secretion in relation to insulin sensitivity in nondiabetic postmenopausal women.

To evaluate mechanisms underlying the close association between insulin secretion and insulin sensitivity, insulin sensitivity was evaluated by the euglycemic-hyperinsulinemic clamp technique (M/I(clamp)) and insulin secretion was determined from the 75-g oral glucose tolerance test (OGTT) and from the glucose-dependent arginine-stimulation test in 81 nondiabetic postmenopausal women, all aged 61

Porous silicon as a neural electrode material.

The electrical properties of the solid state/fluid (Ringer solution) interface for phosphorous- and boron-doped porous silicon are reported and the benefits of using porous silicon as neural recording electrodes are discussed. The impedance, reactance and resistance for doped porous and planar silicon, in Ringer solution, were compared to gold electrodes. Planar silicon displayed approximately a t

The weevil Brachyderes lusitanicus (F.) is recorded for the first time from Denmark. In 2006 a population was found at Flyvesandet, Agernæs on the north coast of Fyn. The first Danish specimen was a found on the same locality in september 2000, but this has only recently been indetified correct. The second specimen was found in november 2005. Inspired by this finding the site has been visited by s
