Vetenskapliga perspektiv på lärande, undervisning och utbildning i olika institutionella sammanhang : utbildningsvetenskaplig forskning vid Lunds universitet

Bidragen i antologin har skrivits av forskare verksamma vid eller associerade med Lunds universitet och samlats under sex olika teman. Under temat "Lärande" finns fem kapitel som undersöker innehållet i lättlästa myndighetstexter, vad förståelse egentligen är och kunskapsinnehållets betydelse i lärande samt hur och varför digitala läromedel kan bidra till lärande. Bakom temat "Utbildning" finns fy

Applications of protein-based capacitive biosensors for the detection of heavy-metal ions

Three different methods of using protein-based capacitive biosensors for the detection of heavy-metal ions are presented. The metal-binding proteins SmtA, S100A12, MerP and four modified MerPs were immobilised as the bio-recognition element on self-assembled monolayer-modified gold electrodes. Capacitance was measured using potential square step or electrical impedance spectroscopy. The protein-me

Galiellalactone Synthetic Studies

Popular Abstract in English Prostate cancer is one of the most common causes of death for men. This disease can be detected at different stages and if it is detected at an initial stage there are many therapies to choose from. However, if it is detected at an advanced stage the options are reduced and most of the treatments are aggressive in an effort to extend the patient’s life. The most common In search for remedies and treatments, science has recurred to Mother Nature. This is where galiellalactone was found, a fungal metabolite isolated from Galiella rufa in 1990. Since then chemists and biologists have been studying its properties and found it to be a potential candidate against castration-resistance prostate cancer (CRPC). The development of a new drug requires many studies of the c

Dynamic Wetting of Solid Surfaces, Influence of Surface Structures and Surface Active Polymers

The effect of surface structures on the dynamics of wetting was investigated through measurements of the dynamic contact angle and spreading velocity of oil droplets spreading over surfaces with parallel and gridlike V-shaped channels. A rim of liquid was observed to spread out in the channels ahead of the dropfront after a short time of spreading (seconds). The characteristics of the rim were inv

State of the Art Report on Drone-Based Warfare

State of the art report on the latest cultural discourse and debate over contemporary forms of drone based warfare. primarily resulting from the disciplines of Law, Political Science, and Geography. 2014.

The venture capitalist and the board of directors in SMEs: roles and processes

The paper provides an attempt to direct the research in the area of venture capitalist and the board of directors in SMEs. Issues about boards in venture capital-backed technology based industrials are explored, and various research designs are used to meet different research questions. Empirical results indicate that venture capital firms purposefully use boards in the portfolio firm, and boards

Islanding Detection in Power Systems

As the contribution of dispersed or distributed energy resources (DER) to the electric power production increases, the effects on the power system grow more important. As an example a critical situation may arise if protective relays trip a large part of the dispersed generation due to undervoltage at a short-circuit event. On the other hand it is crucial that the protection system acts correctly

A Greedy Search for Improved QC LDPC Codes with Good Girth Profile and Degree Distribution

Search algorithms for regular and irregular quasi-cyclic LDPC block codes with both good girth profile and good degree distribution are presented. New QC LDPC block codes of various code rates are obtained and their bit error rate performance is compared with that of the corresponding LDPC block codes defined in the IEEE 802.16 WiMAX standard of the same block length and code rate.
