Rapid cosmetic improvements in nail psoriasis patients treated with K101-03
No full textBackground Nail psoriasis can cause embarrassment and stigmatization. A therapy that produces rapid cosmetic improvements could therefore make a difference to patients. Objectives Data from an 8‐week open-label multicenter study were analyzed to assess the efficacy of K101-03, a Nail psoriasis containing propylene glycol, glycerol, urea and lactic acid, in adult patients with nail psoriasis. Patients and Methods Patients (n=35) applied K101-03 to their affected nails once daily for 8 weeks. They rated the overall appearance of a selected nail (the “target” nail) versus baseline on a 4‐point scale after 1, 2, 4 and 8 weeks of treatment. At the same time points, they also assessed whether, compared to baseline, the target nail was less thickened, less discolored, less brittle and softer. Results After 8 weeks of K101‐03 treatment, the overall appearance of the target nail was improved in 94.1% of patients (95% confidence interval [CI] 86.2–100). After 1 week of treatment, 70.6% of patients (95% CI 55.3–85.9) reported an overall improvement in the target nail and 52.9% of them reported that their target nail was less discolored. Three‐quarters of patients reported softening of their target nail after 8 weeks of treatment. Conclusion In summary, K101-03 rapidly improved the appearance and other physical attributes of nails affected by psoriasis

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The near-infrared luminosity function of cluster galaxies beyond redshift one
No full textAims. We determined the K-s band luminosity function (LF), and inferred the corresponding stellar mass function, of cluster galaxies at redshift z similar or equal to 1.2, using near-infrared images of three X-ray luminous clusters at z = 1.11, 1.24, 1.27. Methods. The composite LF was derived down to M* + 4, by means of statistical background subtraction, and is well described by a Schechter function with K-s* = 20.5(-1)(+0.4) and alpha = -1.0(-0.3)(+0.2). Using available X-ray mass profiles we determined the M/L ratios of these three clusters, which tend to be lower than those measured in the local universe. Finally, from the Ks band composite LF we derived the stellar mass function of cluster galaxies. Results. With these data, no significant difference can be seen between the cluster galaxies LF and the LF of field galaxies at similar redshift. We also found no significant evolution out to z similar or equal to 1.2 in the bright ( 2. Conclusions. The results obtained in this work support and extend previous findings that most of the stars in bright galaxies were formed at high redshift, and that K-s-bright (M > 10(11) M circle dot) galaxies were already in place at z similar or equal to 1.2, at least in the central regions of X-ray luminous clusters. Together with recent results on the field galaxy stellar mass function, this implies that most of the stellar mass is already assembled in massive galaxies by z similar or equal to 1, both in low and high density environments
Deep near-infrared imaging of RDCS J1252.9-2927 at z=1.237 - The colour-magnitude diagram
No full textWe present deep Soil and ISAAC near-infrared imaging data of the X-ray luminous galaxy cluster RDCS J1252.9-2927. The ISAAC data were taken at the ESO Very Large Telescope under very good seeing conditions and reach limiting Vega magnitudes of 25.6 and 24.1 in the J- and K-s-bands respectively. The image quality is 0".45 in both passbands. We use these data to construct a colour-magnitude (C-M) diagram of galaxies that are within 20" of the Cluster center and brighter than K-s = 24, which is five magnitudes fainter than the apparent magnitude of a L* galaxy in this cluster. The C-M relation is clearly identified as an over-density of galaxies with colours near J - K-s = 1.85. The slope of the relation is -0.05 +/- 0.02 and the intrinsic scatter is 0.06 mag with a 90% confidence interval that extends from 0.04 to 0.09 mag. Both the slope and the scatter are consistent with the values measured for Clusters at lower redshifts. These quantities have not evolved from z = 0 to z = 1.24. However, significant evolution in the mean J - K-s colour is detected. On average, the galaxies in RDCS J1252.9-2927 are 0.25 mag bluer than early-type galaxies in the Coma cluster. Using instantaneous single-burst solar-metallicity models. the average age of galaxies in the center of RDCS J1252.9-2927 is 2.7 Gyrs
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
