[Motivation for Specialisation in General Practice - A Quantitative Study of NRW's Medical Students in Support of Targeted Recruitment].

Aim Of Study: Due to forecasted shortage of general practitioners, we conducted an online survey of all medical students in North-Rhine-Westphalia to identify and quantify determinants in medical students' decision to specialize in general practice (GP).

Methodology: To identify the motives driving the choice of GP as a career, responses of 3976 participants (22.6% of medical students invited) were subjected to factor analysis.

Influences of Dilute Organic Adsorbates on the Hydration of Low-Surface-Area Silicates.

Competitive adsorption of dilute quantities of certain organic molecules and water at silicate surfaces strongly influence the rates of silicate dissolution, hydration, and crystallization. Here, we determine the molecular-level structures, compositions, and site-specific interactions of adsorbed organic molecules at low absolute bulk concentrations on heterogeneous silicate particle surfaces at early stages of hydration. Specifically, dilute quantities (∼0.

Reactions and surface interactions of saccharides in cement slurries.

Glucose, maltodextrin, and sucrose exhibit significant differences in their alkaline reaction properties and interactions in aluminate/silicate cement slurries that result in diverse hydration behaviors of cements. Using 1D solution- and solid-state (13)C nuclear magnetic resonance (NMR), the structures of these closely related saccharides are identified in aqueous cement slurry solutions and as adsorbed on inorganic oxide cement surfaces during the early stages of hydration. Solid-state 1D (29)Si and 2D (27)Al{(1)H} and (13)C{(1)H} NMR techniques, including the use of very high magnetic fields (18.

Stereotactic body radiation therapy for nonresectable tumors of the pancreas.

Background: Stereotactic body radiation therapy (SBRT) has emerged as a potential treatment option for local tumor control of primary malignancies of the pancreas. We report on our experience with SBRT in patients with pancreatic adenocarcinoma who were found not to be candidates for surgical resection.

Methods: The prospective database of the first 20 consecutive patients receiving SBRT for unresectable pancreatic adenocarcinomas and a neuroendocrine tumor under an IRB approved protocol was reviewed.
