EPA – en modell för att träna och bedöma dagligt läkarjobb
EPA (entrustable professional activities) avser aktiviteter som ingår i en läkares dagliga arbete och som läkaren ska klara med en definierad grad av självständighet första dagen som legitimerad läkare.En modell för att träna och bedöma sådana aktiviteter kan säkerställa att studenter klarar av det faktiska arbete som ska utföras första dagen efter legitimation, och den tydliggör också progressionEntrustable Professional Activities (EPAs) define observable key tasks that a doctor should be able to do independently after having completed a certain level of education. Progression is facilitated by frequent assessments of the defined activities, with increased degree of independence. The observations should be supported by constructive feed-forward. EPA is currently used in several countries

Enzymatic conversions of polar lipids. Principles, problems and solutions
This text provides a brief overview of the principles of enzymatic lipid conversion and some recent advances in the enzymatic conversion of glycerophospholipids and galactolipids. Lipases and phospholipases are used to exchange fatty acids or the polar group in the lipids. The reactions can be carried out either as hydrolysis-esterification sequences or as one-step transferase reactions. The scope
A kinetic study of almond-β-glucosidase catalysed synthesis of hexyl-glycosides in low aqueous media : Influence of glycosyl donor and water activity
A variety of alkyl and aryl glycosides were investigated as substrates for almond β-glucosidase catalysed synthesis of hexyl-β-D-glycosides in low aqueous hexanol media. The rate-limiting step in the organic media was determined to be the glycosylation of the enzyme. The kinetic constants V max , K m (glycosyl donor) and V max /K m were all influenced by the water activity and they all increased
Influence of water activity on the competition between β-glycosidase-catalysed transglycosylation and hydrolysis in aqueous hexanol
Five different β-glycosidases (Pyrococcus furiosus β-glucosidase, Sulfolobus solfataricus β-galactosidase, Caldocellum saccharolyticum β-glucosidase, almond β-glucosidase and Escherichia coli β-galactosidase) were evaluated as transglycosylation catalysts in hexanol containing various amounts of water. All enzymes catalysed both hydrolysis and transglycosylation of the glycosidic substrates (penty
Thermodynamic and kinetic aspects on water vs. organic solvent as reaction media in the enzyme-catalysed reduction of ketones
The stereoselective reduction of ketones catalysed by alcohol dehydrogenase from Thermoanaerobium brockii was studied in different reaction media, hexane at controlled water activities, hexane with 2.5% water (biphasic) and pure water. The reactions were studied in the temperature range from -1 to 50°C. Increasing the water activity from 0.53 to 0.97 increased the reaction rate 16-fold. The rate w
Useful methods in enzymatic synthesis of peptides : A comparative study focussing on kinetically controlled synthesis of Ac-Phe-Ala-NH2 catalyzed by α-chymotrypsin
The usefulness of different reaction systems for enzymatic peptide synthesis was evaluated by studying the formation of a dipeptide from equimolar amounts of acyl-donor and acyl-acceptor. α-Chymotrypsin (EC 3.4.21.1.), dissolved or deposited on celite,was used for the synthesis of Ac-Phe-Ala-NH2 from Ac-Phe-OEt and H-Ala-NH2. Reactions were carried out at room temperature (≃ 25°C), if not otherwis
How Standards and Modularity can improve Humanitarian Supply Chain Responsiveness: The Case of Emergency Response Units
Purpose – The purpose of this paper is to increase understanding of the use of standards and modularity for improving responsiveness in the humanitarian context. Design/methodology/approach – Based on a conceptual framework and a systematic literature review, the authors conducted a longitudinal, explorative case on the Emergency Response Unit (ERU) concept in the International Federation of Red C
Improving health in developing countries : reducing complexity of drug supply chains
PurposeUganda is one of many African countries struggling to develop adequate healthcare, particularly in regard to local treatment and access to drugs. The purpose of this paper is to contribute to the understanding of how reducing supply-chain complexity can improve health in developing countries. Design/methodology/approachThis study and evaluation included 50 interviews and 27 site visits of t
Supply chain management - Back to the future?
Purpose - Distribution arrangements are becoming increasingly complex and dynamic in business as well as in consumer markets. The purpose of the present paper is to explore and discuss the theoretical frameworks available to interpret these distribution arrangements, to uncover how they are interrelated and to suggest extensions. Design/methodology/approach - A survey of extant research is underta
Interacting standards : A basic element in logistics networks
Purpose - Logisticians have always viewed standards as solutions for improving operational compatibility and coordination. This paper aims to contribute to a greater understanding of how standards, upon which logistics systems are designed, developed and coordinated, interact with each other and with other resources in a logistics network for the purpose of improving efficiency and effectiveness.
Evaluation of simple enzyme kinetics by response surface modelling
The activity of a horse liver alcohol dehydrogenase catalysed reduction of cyclohexanone was investigated by using a central composite circumscribed design in which two parameters (pH and cyclohexanone concentration) were varied. By log transformation of the substrate concentration an adequate model could be obtained from which reliable kinetic constants and pH profiles were determined.
Economic logics in the construction industry
Construction is claimed to be fragmented, contract focused, short sighted and characterised by price competition. These are typical aspects of what is considered the traditional market approach where each company is seen as autonomous and transaction oriented towards others. During the last few decades, numerous theoretical approaches have questioned these assumptions. Studies also on construction
Towards supply chain coordination and productivity in a three echelon supply chain action research study
Purpose-The purpose of this paper is to address the issue of supply management coordination among a prominent contact lens company (customer), its carton supplier (first tier), and paperboard supplier (second tier). Adopting concepts within the theory of swift and even flow, the authors integrate the physical (material) and information flow among these supply partners to ensure higher productivity
Lean and six sigma – critical success factors revisited
Purpose – The purpose of this paper is to provide a review of the critical success factors (CSF) for lean and six sigma and an analysis of these CSF as compared to previously popular change methods. Design/methodology/approach – The paper uses a literature search and comparative analysis complemented with examples from previous case studies. Findings – With only slight variations, the critical suc
"I have got diabetes!" - Interviews of patients newly diagnosed with type 2 diabetes
Background: To be diagnosed with type 2 diabetes is a challenge for every patient. There are previous studies on patients' experience in general but not addressing the increased cardiovascular risk and multifactorial treatment. The aim of this study was to explore the thoughts, experiences and reactions of newly diagnosed patients with diabetes to this diagnosis and to the risk of developing compl

Rock, paper, scissors : Lessons from the steel industry - Should paper listen?
The US paper industry should understand competent management and continuous innovation in a competitive environment in order to ensure the proper growth of the industry. It is suggested that investment in new technology and processes ensures the benefits to companies and the government policies is not the optimal solution to improve the industry. The United States is although a powerful nation but
Chloroperoxidase catalysed oxidation of benzyl alcohol using tert-butyl hydroperoxide oxidant in organic media
The quantitative oxidation of benzyl alcohol to benzaldehyde using the enzyme chloroperoxidase (CPO) from Caldariomyces fumago as catalyst and tert-butyl hydroperoxide (t-BuOOH) as a cosubstrate for the enzyme, in organic solvent is demonstrated. The enzymatic transformation of primary alcohols to aldehydes has not previously been shown in predominantly organic solvent using CPO, and in aqueous me
