Three alkali swelling methods were used to treat two kinds of kraft pulp fibers. The morphological and chemical properties of the treated fibers were elucidated in terms of alkali concentration, with the aim of developing bulky paper and conserving wood resources. The effects of beating before and after alkali swelling were examined. The water retention value of fibers increased when higher con...

Antigen prepared from gonococci by extraction with alkali has the ability to sensitize erythrocytes for agglutination or indirect haemolysis by corresponding antisera (Chanarin, 1954; Maeland, 1966; Thomas and Mennie, 1950). These indirect techniques have been used for the study of endotoxin preparations from gonococci. Endotoxins, however, require treatment with alkali before sensitization, ex...

The presence of defects in cold mercerizing of cotton goods led to the creation of a new method, called hot mercerizing in which caustic soda solution is used at a high temperature. Hot mercerizing is successfully used in cotton blended with some other fibers. In cotton/polyester blend fabrics, this treatment serves a dual purpose: subjectively, it imparts a silklike soft handle to the po...

In 1960 a 5-year-old girl was found to have developed accelerated hypertension (B.P. 190/150) with blood urea 119 mg/ 100 ml. An intravenous pyelogram showed a small scarred left kidney (5-3 by 32 cm). There was also upper pole scarring with clubbed calyces on the right side. Left nephrectomy was performed and histological examination of the kidney confirmed pyelonephritic changes, and showed i...

Hydroxyproline-poor glycoprotein contains a single polypeptide chain with lysine at the N-terminus. Removal of carbohydrate attached to serine by alkali treatment produces two polypeptide fractions. Labeling with (35)S indicates that most serine residues having a carbohydrate substituent removed by alkali occur on the polypeptide fraction of lower molecular weight. Following alkali treatment, t...

In this study, time of calcium phosphate formation on Ti6Al4V alloy with or without alkali and heat treatments was investigated. Specimens were soaked in 0, 5, 10 M solutions of NaOH at temperatures of 60 or 80 °C for 24, 72 h. Their surfaces were characterized using scanning electron microscopy and thin film X-ray diffraction. It was found that optimum condition is 72h soaking in 5 M NaOH in 8...
