Intra-Articular Osteochondroma of the Hip. Total Hip Replacement After Tumor Resection in a Young adult - A Case Report.

Introduction: Osteochondroma is the most common benign bone tumor (20-50%). It is located predominantly in the metaphysis of the long bones, and much less frequently, the proximal femur and acetabulum. Osteochondroma can eventually lead to hip osteoarthritis and limit patients' functional activities.

Observed kinetics for the production of diethyl carbonate from CO and ethanol catalyzed by CuNi nanoparticles supported on activated carbon.

Monometallic and bimetallic Cu:Ni catalysts with different Cu:Ni molar ratios (3:1, 2:1, 1:1, 1:2, 1:3) were synthesized by wetness impregnation on activated carbon and characterized by TPR (temperature programmed reduction), XRD (X-ray diffraction) and XPS (X-ray photoelectron spectroscopy). The synthesized catalysts were evaluated in the gas phase production of diethyl carbonate from ethanol and carbon dioxide. The largest catalytic activity was obtained over the bimetallic catalyst with a Cu:Ni molar ratio of 3:1.

Kinetic Study of Liquid-Phase Glycerol Hydrodeoxygenation into 1,2-Propanediol over CuPd/TiO-Na.

Hydrodeoxygenation (HDO) kinetics of glycerol into 1,2-propanediol (1,2-PDO) in the liquid phase is studied on Cu-Pd/TiO catalysts. At a stirring speed higher than 480 rpm and an average diameter of the catalyst particles smaller than 89.5 μm, no mass transfer resistance artifacts are observed.

Nature and Distribution of Cu and Pd Species in CuPd/TiO-Na Bimetallic Catalysts for Glycerol Hydrodeoxygenation.

We demonstrated recently that CuPd/TiO-Na bimetallic catalysts synthesized by sequential wet impregnation are active, selective, and stable for the hydrodeoxygenation (HDO) of glycerol into propylene glycol at low H pressure. The present study reports on the nature and distribution of Cu and Pd surface species in CuPd/TiO-Na bimetallic catalysts using different scanning transmission electron microscopy techniques that supply cluster-specific alloying details. In particular, we used atomic-resolution -contrast imaging, X-ray energy-dispersive spectroscopy, and electron energy-loss spectroscopy.

Inputs and distributions of synthetic musk fragrances in an estuarine and coastal environment; a case study.

Synthetic musks are ubiquitous contaminants in the environment. Compartmental distributions (dissolved, suspended particle associated and sedimentary) of the compounds throughout an axial estuarine transect and in coastal waters are reported. High concentrations of Galaxolide (HHCB) and Tonalide (AHTN) (987-2098 ng/L and 55-159 ng/L, respectively) were encountered in final effluent samples from sewage treatment plants (STPs) discharging into the Tamar and Plym Estuaries (UK), with lower concentrations of Celestolide (ADBI) (4-13 ng/L), Phantolide (AHMI) (6-9 ng/L), musk xylene (MX) (4-7 ng/L) and musk ketone (MK) (18-30 ng/L).
