Raman optical activity (ROA) spectroscopy has been applied for the first time to study the interaction of cisplatin with DNA. The knowledge about the structure of DNA-metal ion cross-links and hence the mechanism of the drug action is fundamental for the development of new antitumor drugs. At the same time, there is an urgent need to search for new methods for monitoring of this effect at the t...

To understand the corporate performance of Japanese firms in the twentieth century, we have constructed a comprehensive database that includes asset, capital composition, profitability, and other variables relating to corporate governance structure. In this paper, we briefly introduce our project and report preliminary results of research on corporate performance and its determinants. We survey...

BACKGROUND A recent study of adults aged >or=50 years reporting knee pain found an excess of radiographic knee osteoarthritis (knee ROA) in symptomatic males compared to females. This was independent of age, BMI and other clinical signs and symptoms. Since this finding contradicts many previous studies, our objective was to explore four possible explanations for this gender difference: X-ray vi...

In our contribution, we model bank profitability via return-on-assets (ROA) and return-on-equity (ROE) in a stochastic setting. We recall that the ROA is an indication of the operational efficiency of the bank while the ROE is a measure of equity holder returns and the potential growth on their investment. As regards the ROE, banks hold capital in order to prevent bank failure and meet bank cap...

BACKGROUND Digital infrared thermal imaging is a means of measuring the heat radiated from the skin surface. Our goal was to develop and assess the reproducibility of serial infrared measurements of the knee and to assess the association of knee temperature by region of interest with radiographic severity of knee Osteoarthritis (rOA). METHODS A total of 30 women (15 Cases with symptomatic kne...

Two UV brights stars in globular clusters, ROA 5701 (ω Cen) and Barnard 29 (M 13) are analysed from highresolution UV and optical spectra. The main aim is the measurement of iron abundances from UV spectra obtained with the HST-GHRS. In addition atmospheric parameters and abundances for He, C, N, O, and Si are derived from optical spectra (ESO CASPEC) for ROA 5701 or taken from literature for B...

Following its first observation over 40 years ago, Raman optical activity (ROA), which may be measured as a small difference in the intensity of vibrational Raman scattering from chiral molecules in rightand left-circularly polarized incident light or, equivalently, the intensity of a small circularly polarized component in the scattered light using incident light of fixed polarization, has evo...

Our calculations show that the Reduction-coupled Oxo Activation (ROA) principle, which we reported at Irsee VI to play the critical role for the selective oxidation of n-butane to maleic anhydride by vanadium phosphorous oxide (VPO), also plays the critical role for the MMO activation of propane, as speculated during Irsee VI. However for MMO, this ROA principle involves Te=O and V rather than ...

Aim: To determine the prevalence and the hygiene methods used by 6-16-year-old private school children and adolescents to clean removable orthodontic appliances (ROA) in the city of Pelotas, RS, Brazil. Methods: A cross-sectional study was conducted in private schools located in the urban area after the school tutors signed an informed consent form. Questionnaires were applied to children using...

Employee attitude data from 35 companies over 8 years were analyzed at the organizational level of analysis against financial (return on assets; ROA) and market performance (earnings per share: EPS) data using lagged analyses permitting exploration of priority in likely causal ordering. Analyses revealed statistically significant and stable relationships across various time lags for 3 of 7 scal...
