Surface Properties of Antigen-Antibody Complexes

In this paper, the authors show that liquid-liquid partition chromatography in an aqueous two-phase system offers unique possibilities of comparing the overall surface properties of intact antibodies in solution before and after binding of antigen. The authors demonstrate that the surface properties of antigen-antibody complexes are dependent on the variable regions of the antibodies, the nature o

Improved removal of anti-A and anti-B antibodies from plasma using blood-group-active haptens

Highly efficient anti-blood group A and B immunoadsorbents for extracorporeal treatment were developed by immobilizing A and B trisaccharide and A tetrasaccharide haptens on Sepharose 4FF and Fractogel TSK using three different methods. The adsorption of the IgG and IgM anti-A antibodies was essentially the same regardless of the A hapten used or the method of oligosaccharide coupling. The adsorpt

Dynamic Modeling of Non-equilibrium Latex Particle Morphology Development During Seeded Emulsion Polymerization.

We have developed software to simulate the development of non-equilibrium latex particle morphologies produced by seeded emulsion polymerization. The diffusion of second stage polymer radicals within seed particles controls the development of morphology in a large number of systems. Knowledge of the conditions present within the latex particles during the reaction is required in order to model thi

Lead abundance in the uranium star CS 31082-001

In a previous paper we were able to measure the abundance of uranium andthorium in the very-metal poor halo giant BPS CS31082-001, but only obtained an upper limit for the abundanceof lead (Pb). We have got from ESO 17 h of additional exposure on thisstar in order to secure a detection of the minimum amount of leadexpected to be present in CS 31082-001, the amountarising from the decay of the orig

Two-dimensional surface temperature measurements of burning materials

A new technique for two-dimensional temperature measurements of burning surfaces is presented. Laser-induced phosphorescence from a thermographic phosphor material applied to a surface of investigation was measured with a fast framing camera. The phosphor was excited by the 4th harmomic from a pulsed Nd:YAG operating at 10 Hz. The phosphorescence images measured by eight consecutively gated CCD de

Single-peaked compatible preference profiles: some combinatorial results

This paper examines combinatorial problems in connection with single-peaked preference orderings on a unidimensional scale. A binary relation, dominance, is defined on the set of connected orderings. Relevant properties of the corresponding poset and cover graph are discussed. A formula for the number of pairs of connected orderings consistent with spatial single-peakedness is derived. The total n

Heart transplantation across the antibodies against HLA and ABO

We have intentionally performed heart transplantation in a 5-year-old child, despite the most unfavourable risk factors for patient survival; the presence of high level of antibodies against donor's human leucocyte antigen (HLA) class I/II and blood group antigens. Pretransplant treatment by mycophenolate mofetil, prednisolone, tacrolimus, intravenous immunoglobulin, rituximab, protein-A immunoads

Patient flows in the care process of mandibular third molar surgery

Our aim was to describe patient flows in mandibular third molar surgery at ora I and maxillofacial specialist units. Our hypothesis was that there are variations in how care is delivered and that the variations could be explained by inter-individual variations in surgeons' practice,the quality of the radiographs appended to the referral, and the staffing of the specialist units. A flow chart was c

Exchange-correlation energy of a multicomponent two-dimensional electron gas

We discuss the exchange-correlation energy of a multicomponent (multivalley) two-dimensional (2D) electron gas and show that an extension of the recent parametrization [C. Attaccalite, S. Moroni, P. Gori-Giorgi, and G. B. Bachelet, Phys. Rev. Lett. 88, 256601 (2002)] of the exchange-correlation energy by Attaccalite describes well also the multicomponent system. We suggest a simple mass dependence

Comparative dosimetry of diode and diamond detectors in electron beams for intraoperative radiation therapy

The aim of the present study is to examine the validity of using silicon semiconductor detectors in degraded electron beams with a broad energy spectrum and a wide angular distribution. A comparison is made with diamond detector measurements, which is the dosimeter considered to give the best results provided that dose rate effects are corrected for. Two-dimensional relative absorbed dose distribu

Tropical forests and the global carbon cycle: impacts of atmospheric carbon dioxide, climate change and rate of deforestation

The remaining carbon stocks in wet tropical forests are currently at risk because of anthropogenic deforestation, but also because of the possibility of release driven by climate change. To identify the relative roles of CO2 increase, changing temperature and rainfall, and deforestation in the future, and the magnitude of their impact on atmospheric CO2 concentrations, we have applied a dynamic gl

Clinical outcome of erythema migrans after treatment with phenoxymethyl penicillin

In a 5 y retrospective follow-up study in southern Sweden of 708 adult individuals with erythema migrans as the single manifestation of Lyme borreliosis, the clinical outcome and the antibiotic treatment were studied. 80%, were treated with phenoxymethyl penicillin, 15% with doxycycline and 5% with other antibiotics. Phenoxymethyl penicillin and doxycycline were extremely effective: 98 and 94% of

Skriv med egna ord. En studie av läroprocesser när elever i grundskolans senare år skriver "forskningsrapporter".

Abstract Nilsson, Nils-Erik, Write in Your Own Words: A Study of Learning Processes in Research Report Writing in School. The thesis examines sixty pupil texts produced in the school activity called pupil research at secondary level of a Swedish school where this activity was scheduled one day per week. The purpose of this thesis is to develop knowledge about the writing done by pupils under the
