The objective of this review is to report on the progress of the Brigham and Women's Hospital Rheumatoid Arthritis Sequential Study (BRASS) Registry data collection and summarize previous research in understanding therapeutic response to DMARDs using clinical and genetic data. The BRASS Registry, established in 2003, is a large, single-centre, prospective and observational cohort of 1100 RA pat...

wear is a complicated phenomenon caused by the relative movement of two contacting surfaces compressed together by a normal force. prediction of the wear, in most cases, requires various experiments and microstructural characterization of the contacting surfaces. mathematical models based on physical concepts could provide considerable help in understanding the physical behavior and hence the p...

With the rapid advances in tumor genetics, an increasing number of amplifications have been identified in various human neoplasms (4). Examples of oncogenes amplified in tumors include N-myc and HER-2/neu, which have been proposed as prognostic markers in neuroblastoma and breast cancer, respectively (5,7). To date, most of the information on the amplification of genes has been gathered from co...

background: the aim of this work was to study the output factors for linac using different ionization chambers and build up caps. materials and methods: output factors were measured for open square fields (3 × 3 cm to 40 × 40 cm) defined by collimator jaws for 6 and 15 mv photon beams from a varian clinac 2100c accelerator were measured. the measurements in air were performed using compact cyli...

OBJECTIVES: The key hypothesis of this project was that both chemical and physical factors associated with real plumbing systems may influence copper pitting and brass dezincification corrosion, and thus the project was aimed at better understanding these factors. In addition to a comprehensive review of the literature on brass dezincification in potable water systems, experimental work was und...

A Massey diffuse convolutional decoder was simulated in the IBM 7030 computer 'aid used to decode binary digital error patterns measured at 2*4-00 bits/sec on an HF radio circuit and on a multiple link data circuit dominated by a tropospheric scatter path. It was found that the simulation performed at least as well as previous cyclic code simulations on HF radio and better than cyclic codes on ...

The effect of marine algae Sargassum wightii extract on corrosion inhibition of brass in phosphoric acid was investigated by weight-loss method, potentiodynamic polarization and electrochemical impedance spectroscopy studies. The inhibition efficiency is found to increase with increasing concentration of extract and decreases with rise in temperature. The inhibitive effect could be attributed t...
