Miniaturized, Membrane-Based and Environmentally Green Sample Preparation Systems: Applications for Biological and Environmental Aqueous Samples

Contemporary advancements in miniaturization of analytical systems have advantageously fostered development, automation, and hyphenation of a variety of sample preparation techniques. Among several downscaled extraction designs, porous synthetic polymeric membranes (such as flat sheet (FS) or hollow fiber (HF)) have been utilized for membrane-based extraction, separating two aqueous phases (as in

Radiography and bone scintigraphy in osteoarthritis of the knee: comparison with MR imaging

Popular Abstract in Swedish Röntgen och isotopundersökning vid knäledsartros: en jämförelse med magnetkamera-undersökning Denna avhandling utgör en del av ett större forskningsprojekt om tidig artros (s.k. broskförslitning) i knäleden. Studien omfattar nästan 200 personer med knäsmärta, som när projektet startade 1990 var mellan 35 och 54 år. Vår avsikt är att under minst 10 års tid regelbundet uThe aim was to compare radiography of the tibiofemoral joint (TFJ) and the patellofemoral joint (PFJ), as well as bone scinigraphy with MR imaging in middle-aged individuals with chronic knee pain in the format of a prospective study of knee osteoarthritis. Individuals aged 35-54 years with chronic knee pain were identified. The prevalence of chronic knee pain was 15% (279/2000). Within this grou

Globalization, Transparency and Economic Growth - The Vulnerability of Chinese Firms to Macroeconomic Shocks

The process of globalization encompasses economic and financial integration. The abolition of capital controls and the dismantling of barriers of different kinds will expose previously sheltered companies to shocks on the global economic arena. Policy-makers in already globalized countries have learned that market participants should be prepared in due time to meet the new exposure to fluctuating

Schartau och herrnhutismen: Erfarenheten, själavårdsbreven, efterverkningarna

1. Som en reaktion mot herrnhutismens ”blandade” lära definierades den rätta läran av Schartau och än mer av hans efterföljare ofta mycket snävt. Den så kallade bokstriden som bröt ut när andra bandet av Schartaus brev 1830 publicerats, avgränsade negativt schartaulärjungarna genom att de undvek de flesta uppbyggelse- och andaktsböcker. Schartau drev på den konfessionalisering som från omkring 182

Culture and compliance: an anthropologist’s view

The concept of "culture" is often used improperly in the literature and training on business ethics and compliance. A more sophisticated view of 'culture of compliance' is required. Published in a magazine for ethics and compliance professionals

Design criteria for assessment of vehicle climate systems

The combined thermal effects of convection, radiation and conduction in a vehiclecompartment need special measuring equipment accounting for spatial and temporalvariations in the driver space. The most sophisticated equipment measures local heat fluxes at defined spots or areas of a man-shaped manikin. By calibration of segment heat fluxes with thermal sensation votes of panel of subjects, manikin
