Kraft black liquor lignin is a biofuel that is separated from the cellulose during kraft pulping. Improved technology and energy integration in paper mills have led to an energy surplus at many mills. It is therefore of great interest to extract the lignin from the pulp mill and sell it as fuel to replace fossil fuel in other furnaces. The fractionation of kraft black liquor with a total dry matte
Clozapine has recently been associated with venous thromboembolism. The aim of this study was to describe three elderly patients in whom olanzapine therapy was associated with venous thromboembolism. During a 4-month period at the same psychogeriatric clinic, three elderly patients (an 89-year-old male, a 78-year-old male and an 83-year-old female) developed deep venous thrombosis shortly after tr
Learning of classically conditioned eyeblink responses depends on mechanisms within the cerebellum. It has been suggested that climbing fibres from the inferior olive transmit the unconditioned stimulus signal to the cerebellum. We have previously shown that the pathway from the deep cerebellar nuclei to the inferior olive inhibits olivary activity. It is known that repeated presentation of the co
Abstract. In this paper we examine subalgebras on two generators in the univariate polynomial ring. A set, S, of polynomials in a subalgebra of a polynomial ring is called a canonical basis (also referred to as SAGBI basis) for the subalgebra if all lead monomials in the subalgebra are products of lead monomials of polynomials in S. In this paper we prove that a pair of polynomials ff; gg is a can
Although the biological properties of staphylococcal enterotoxin A (SEA) have been well characterized, structural insights into the interaction between SEA and major histocompatibilty complex (MHC) class II have only been obtained by modeling. Here, the crystal structure of the D227A variant of SEA in complex with human MHC class II has been determined by X-ray crystallography. SEA(D227A) exclusiv
The uniaxial chain alignment and equatorial patterning of poly [9,9-bis(2-ethylhexyl)fluorene-2,7-diyl] (M-n = 29 kg/mol, M-w = 68 kg/mol) thin films atop rubbed polyimide substrates have been studied by grazing incidence X-ray diffraction. This specific molecular weight yields among the highest observed levels of chain alignment and optical anisotropy and, after thermal annealing, the sample unde
Four different ways to detect Kraft and soluble pine lignin using either soluble or immobilised Trametes hirsuta laccase have been investigated. In the first, the concentration of lignin was measured using laccase in homogeneous medium with a Clark electrode. In the second, laccase immobilised onto aminated porous glass beads was used in a reactor submerged into the lignin containing solution and
A chip for digital intermediate frequency filtering is introduced. The filter is intended move most of the analog intermediate frequency filtering to the digital domain in systems like the American mobile radio system (IS-54). It is a wave digital lattice filter realized with bit-serial arithmetic. Furthermore, a technique for local clocks on chip is presented. The method is based on a ring oscill
An external device ("rottometer") specially designed to measure knee joint rotation was developed and evaluated with respect to its validity. Simultaneous measurements were made with the rottometer and Roentgen stereometric analysis (RSA) in five patients with implanted tantalum markers in the tibia and femur. Measurements of internal and external rotation were made at 90 degrees and 60 degrees of
We report experimental oscillator strengths for 88 Ti I transitions covering the wavelength range 465-3892 nm, 67 of which had no previous experimental values. Radiative lifetimes for 13 energy levels, including the low energy levels 3d(2)(F-3) 4s4p ((3)p) z(5)D(j)degrees have been measured using time-resolved laser-induced fluorescence. Intensity-calibrated Ti I spectra have been measured using F
This paper provides an overview of the state-of- the-art radio propagation and channel models for wireless multiple-input multiple-output (MIMO) systems. We distinguish between physical models and analytical models and discuss popular examples from both model types. Physical models focus on the double-directional propagation mechanisms between the location of transmitter and receiver without takin
The shear-induced transitions between an oriented lamellar phase and shear-induced multilamellar vesicles (MLVs) in a nonionic surfactant system were studied by deuterium rheo-NMR spectroscopy as a function of time in start-up experiments at several temperatures and shear rates. By starting from an initial state of oriented lamellae and observing the transformation to the final steady state of MLV
Ovarian cancer is usually found at a late stage when the prognosis is often bad. Relative survival rates decrease with tumor stage or grade, and the 5-year survival rate for women with carcinoma is only 38%. Thus, there is a great need to find biomarkers that can be used to carry out routine screening, especially in high-risk patient groups. Here, we present a large-scale study of 64 tissue sample
The human Simpson-Golabi-Behmel syndrome (SGBS) preadipocyte cell strain provides a unique and useful tool for studies of human adipocyte biology. The cells originate from an adipose tissue specimen of a patient with SGBS. They are neither transformed nor immortalized, and provide an almost unlimited source due to their ability to proliferate for up to 50 generations with retained capacity for adi
The Five Aspects Meal Model (FAMM) is a structured approach towards explaining what makes up an entire meal experience. One aspect in particular, the management control system, has a clear potential of being developed to increase the practical impact of the model. Scholars suggest that the management control system aspect works backstage, where matters of computer work, handling statistics, market
Objectives: To investigate the bactericidal activity of antiviral and anticancer nucleoside analogues against a variety of pathogenic bacteria and characterize the activating enzymes, deoxyribonucleoside kinases (dNKs). Methods: Several FDA-approved nucleoside analogue drugs were screened for their potential bactericidal activity against several clinical bacterial isolates and type strains. We ide
Highly purified plasma membranes from spinach (Spinacia oleracea L.) leaves contained phosphatidylinositol (PtdIns) kinase activity that was firmly associated with the membrane. The enzyme was solubilized by detergent treatment (2% [w/v] Triton X-100) and purified by heparin-Sepharose and Q-Sepharose chromatography. Two enzymically active fractions, QI and QII, both exhibiting PtdIns 4-kinase acti
Objective: While beta(2)-agonists for the acute treatment of preterm labour unequivocally reduce the odds of delivery within 48 hand 7 days, they have been associated with substantial maternal and fetal side effects. We aimed to compare side effect profiles of beta(2)-agonist tocolytics. Study design: Pragmatic comparison of ritodrine, salbutamol and terbutaline from re-analysis of data obtained w
There is a paucity of empirical research on the impact of delirium on professionals' reactions, interpretations or attitudes to people in a delirious state. This is striking because it stands to reason that it is demanding to take care of a person who is disoriented, perhaps agitated and who may hallucinate and/or act in a manner that calls for interventions involving the use of force or actions t
