PURPOSE To define a method of stabilizing stones during extracorporeal (SWL) and intracorporeal lithotripsy with a thermosensitive polymer. MATERIALS AND METHODS Using a thermosensitive polymer that is either a liquid or a gel, depending on the temperature, both calcium oxalate and plaster of Paris phantom stones were placed in the polymer gel or saline, and SWL was performed. Comparisons wer...

We have calculated binding surfaces for cla changes (along the Bain path) and changes of the atomic volume of metallic systems undergoing martensitic transformations. We find characteristic differences between the surfaces of nonmagnetic systems (with a close packed low temperature structure) and magnetic systems (with a less close packed low temperature structure). The ab initio calculations h...

The growth and propagation behavior of austenite-to-bainite isothermal transformation in laser-cladded, Si-rich, and Fe-based coatings is investigated. The crystallographic features, orientation relationship at different isothermal temperatures, and the morphology of the nanostructured bainite are determined. The Nishiyama-Wassermann type orientation relationship is observed at a high temperatu...

OBJECTIVES To compare adolescents' responses to three different styles of cigarette packaging: novelty (branded packs designed with a distinctive shape, opening style or bright colour), regular (branded pack with no special design features) and plain (brown pack with a standard shape and opening and all branding removed, aside from brand name). DESIGN Cross-sectional in-home survey. SETTING...

Rhinorrhea is a prominent symptom of the common cold. Although increases in vascular permeability and serous cell secretion have been demonstrated in human nasal mucus during active rhinovirus infections, changes in mucin constituents have not been quantified. Nonallergic ( n= 48) and asymptomatic allergic rhinitis ( n = 32) subjects were inoculated with rhinovirus type hanks before the spring ...

The present study deals with the formulation, characterization of Metronidazole loaded ethosomal gel for treating oral infection. system comprises 2-5% phospholipids, 20-50% ethanol, 10% propylene glycol, cholesterol and v/v aqueous phase. Cold method was applied to develop ethosome. prepared ethosome evaluated vesicle size, entrapment efficiency,The Optimized Ethosome formulation converted in ...

Phadungath, C. Cream cheese products: A review Songklanakarin J. Sci. Technol., 2005, 27(1) : 191-199 Cream cheese is a soft fresh acid-coagulated cheese product, which is acidified by mesophilic lactic acid starter culture, i.e. Lactococcus and Leuconostoc. Cream cheese products are categorized into two main types based on the different fat content in the initial mix and the final composition....

In order to resolve substrate effects on the adlayer structure and structure formation and on the substrate-adsorbate and adsorbate-adsorbate interactions, we investigated the adsorption of thin films of the ionic liquid (IL) 1-butyl-1-methylpyrrolidinium-bis(trifluoromethylsulfonyl)imide [BMP][TFSA] on the close-packed Ag(111) and Au(111) surfaces by scanning tunneling microscopy, under ultra ...

At low temperature, spheres with a very short-ranged attraction exist as a near-close-packed solid coexisting with an almost infinitely dilute gas. We find that the ratio of the interfacial tension between these two phases to the thermal energy diverges as the range of the attraction tends to zero. The large tensions when the interparticle attractions are short ranged may be why globular protei...
