The relationship between physicians' research activity and professional performance was examined. We have taken into account
their motivation, job satisfaction and the way that research groups are organized. Previous studies have shown that physicians'
research activity has a positive effect on clinical practice. They also show that motivation and job satisfaction are positively
related with research activity. A group of 278 physicians from hospitals in Madrid were surveyed. A structural model was estimated
using SEM techniques. The results indicate both job satisfaction (0.620) and motivation (0.236) are important factors. These
results demonstrate the strategic value of both human resources policies and research management practices within hospitals.

The practice of publishing clinical trials in scientific journals is common, although not without its critics. This study
aims to measure the effect of clinical trials citations on several bibliometric indicators: citations per document (CD); journal
impact factor (JIF); relative h-index (RhI) and strike rate index (SRI). We select all the citable documents published in
the NEJM, Lancet, JAMA, AIM and BMJ, for the period 2000-2004, and record the citations received by those papers from 2000 to 2005. Our results show that clinical
trials have a CD significantly higher than those for conventional papers; JIF is lower when clinical trials are excluded,
especially for NEJM, Lancet and JAMA. Finally, both RhI and SRI seem to be unaffected by clinical trials citations.

SBA-15 materials exhibit important properties including large surface area, highly ordered mesopores, and high stability in a variety of catalytic reactions. In this study, Al and Zr-loaded SBA-15 materials (Si/Zr = 30, Si/Al = 30), 50 molar ratio with Pd (1, 2, and 4% (w/w)) and Pt (0.5 and 1% (w/w)) were tested in the isomerization of C5–C7 linear alkanes. These solids were characterized using thermal gravimetric analysis–differential thermal analysis (TGA–DTA), nitrogen physisorption, and energy dispersive X-ray (EDX). Interestingly, the low porosity SBA-15 materials loaded with 2% (w/w) Pd were most active catalysts for n-heptane isomerization. The mechanochemical addition of tungsten also resulted in the increase of catalytic activity for the reaction. The results herein demonstrate the possibilities of SBA-15 catalysts as a commercial catalyst alternative in the catalytic isomerization of hydrocarbons.
