During the course of a series of studies which had as their aim the elucidation of the role of lysozyme in cartilage metabolism (1-4), it was found that, when egg white lysozyme (LYS) was added to organ cultures of ossifying cartilage (cartilage which contains an epiphyseal growth plate) but not nonossifying cartilage (cartilage which does not contain a growth plate), the lysozyme bound to cart...

Multi-walled carbon nanotubes (MWCNTs) were synthesized on platinum plate electrodes by the chemical vapor deposition (CVD) method. From the results of X-ray photoelectron spectroscopy and voltammetric investigation, the iron nanoparticles used as a catalyst for the MWCNT synthesis were enclosed with MWCNTs. The MWCNTs synthesized on the Pt plate (MWCNTs/Pt) electrode were immediately immersed ...

Nowadays the electrostatic motor finds frequent use in micro-electro-mechanical systems (MEMS) where their drive voltages are below 100 volts. Using moving charged plates in capacitor motors are far easier to fabricate than coils and iron cores. This paper presents a novel design of a three-phase electrostatic rotary motor. It is shown that the angular velocity of the cylindrical type motor is ...

One of the methods used to surface hardening ductile iron is chilled cast iron. Chill as fast cooling rate in mold during solidification and chill thickness greatly affects hardness layer. The main material iron, SS 304. Casting uses sand casting method. Before pouring, plate has been inserted onto pattern that formed mold, then preheated at 700°C. Pouring was carried out a melting temperature ...

Laser assisted spin forming is used to process a galvanized Dual Phase steel with minimum damage to coating, microstructure and material properties. Effective increase in formability was achieved, but no evidence of recrystalization, neither drop in forming force was detected. The paper discusses the possible mechanism of formability improvement through the analysis by EBDS of laser assisted fo...

The aim: study of the effectiveness environmentally safe disinfectants against P. aeruginosa and pathogens main bacteriosis poultry at test facilities.
 Materials methods. To antimicrobial action investigated a mixture epizootic cultures E. coli, aeruginosa, S. aureus, typhimurium, isolated from poultry, bacteriological studies were carried out on objects: galvanized iron, wooden bars (pai...

The synchrotron radiation based spectroscopies X-ray fluorescence and X-ray absorption fine structure are used to detect illness-related changes in the elemental distribution and bonding environment of metals in human nails. The effective atomic number of a collection of nails is determined using two methods, the X-ray transmittance and the scattering method, and is found equal to 7.5 +/- 0.5. ...

On Friday afternoon I had the opportunity to try my hand at blacksmithing while I was attending a museum conference at the Farmer's Museum in Cooperstown. Although I was an industrial arts student at SUNY Oswego many years ago, I never enrolled in metal shop so this was my first encounter with a forge. My first task was to make a nail. As simple as it might appear, there are techniques that hav...

Tibial plateau–leveling osteotomy (TPLO) is an increasingly popular method for treating anterior cruciate ligament ruptures in dogs. In recent years, there have been anecdotal reports of neoplasia near plate implantation sites. In this study, metallurgic analysis was performed on 3 new Slocum TPLO plates, 8 retrieved TPLO plates, and 1 new Synthes dynamic compression plate. The 3 new Slocum pla...
