The various types of phase-change materials (PCMs), which absorb or release stored latent heat when they change phases causing cooling and warming effects, are described and the working principles are outlined. The various ways of incorporating PCMs into textiles for protective clothing are explored, and critical factors identified that determine the effectiveness of PCM cooling and warming effect

The paper seeks to understand how women stereotypes are formed in Ḥekayᾱt Wa Asaṭīr Yamanī [Yemeni Tales and Legends] book compiled by Ali Muhammad Abdo. The paper consists of a preface that includes a theoretical background on the stereotype and the approach used in its detection, and six sections that examine the stereotypical image of women in the book and its genres. The paper uses feminist th

It is shown that the method of protein quantitation by electrophoresis in antibody-containing agarose introduced by Laurell in 1966 can, if slightly modified, be used for quantitation of polyclonal human IgG. This modified method, permits simultaneous quantitation of IgA. It is accomplished within about 9 hours and allows comparison between the charge composition of different IgG-populations. The

The IgG M-components of 70 sera were quantitated by a paper electrophoretic method and by an immunochemical method with the use of an antiserum raised against purified polyclonal IgG. The results obtained by the two procedures were concordant and thereby showed that IgG M-components of different antigenic compositions can probably be quantitated by simple immunochemieal methods. Immunochemical det

A procedure is described, in which two antigens are brought to interact during their electrophoretic migration in an agarose gel containing antiserum. Three fundamental precipitation patterns can be discerned. These patterns correspond to the three basic precipitation patterns obtained with the double radial immunodiffusion procedure of Ouchterlony. The procedure described here can thus be used in

Indirect immunofluorescence was used to demonstrate the presence of protein HC on the surface of a large percentage of normal human peripheral blood lymphocytes. Protein HC is a recently described charge heterogeneous, complex-forming glycoprotein normally present in human plasma, urine and cerebrospinal fluid. The synthesis of protein HC by lymphocytes was indicated by the removal of the glycopro

The surface expression of a recently described plasma glycoprotein called human complex-forming glycoprotein, hetergeneous in charge (protein HC) on a number of different human cell types was investigated. By means of direct and indirect immunofluorescence, protein HC was shown to be associated with the surface of virtually all cells of the investigated normal cell types including erythrocytes, pe

The molecular form and immunochemical properties of the J chain populations released on reduction and carboxymethylation of normal human plasma, milk, saliva and of plasma containing IgA or IgM M-components were investigated. A procedure was devised to release the entire J chain population from these various sources and to produce immunochemically identical J chain populations containing only J ch

Human fetal lever explants were found to secrete protein HC into the medium in molar amounts comparable to those of albumin, alpha 1-antitrypsin and orosomucoid. Incorporation of a radioactive amino acid from the medium into the secreted protein HC demonstrated de novo synthesis. The secreted protein HC had the same size and electrophoretic mobility as protein HC of plasma and urine and gave a rea

This report concerns six cases of multiple myeloma characterized by either no demonstrable monoclonal immunoglobulin in plasma or urine or by trace amounts (less than or equal to 0.1 g/l) of monoclonal kappa chains in the urine. In all cases there was an infiltration of the bone marrow by plasma cells containing kappa chains but no heavy chains. A retrospective analysis was made of 126 consecutive

Lancefield extracts of 19 types of group A streptococci as well as one group C and one group G strain were examined for agglutination of human red cells coated with various anti-Rh antibodies. Fourteen extracts agglutinated one or more of the coated cell samples, while five did not. The agglutination was inhibited by Fc but not by Fab fragments of human IgG. After mouse passages, three of the non-

After electrophoresis of an alkaline extract of type 15 group A streptococci, three main precipitation lines were obtained in diffusion experiments against commercial human polyclonal IgG (lines 1, 2 and 3). Nineteen of 23 sera (83%) from apparently healthy human individuals gave line 3, while 6 of them (26%) gave line 1. The sera giving line 1 did also give line 3. Line 2 was obtained with 2 sera
