Målsättningen med detta projekt var att utveckla ett praktiskt och resurssnålt pedagogiskt instrument för att öka den kontinuerliga återkopplingen och studentaktiveringen i stora föreläsningskurser. Först konsulterades litteraturen när det gäller kunskapen om föreläsningar och återkoppling till stora studentgrupper. Baserat på detta, och på författarnas tidigare erfarenheter, utvecklades sedan ett

Extraordinary transmission of electromagnetic power through sub-wavelength apertures is usually observed in a narrow bandwidth range and the transmission outside this range is low. In this paper, it is shown that the transmission through periodic apertures in an otherwise perfectly electric conducting sheet satisfies a sum rule that relates wavelength regions with transmission above a threshold wi

Abstract in UndeterminedClassical fitting-attitude analyses understand value in terms of it being fitting, or more generally, there being a reason to favour the bearer of value. However, recently such analyses have been interpreted as referring to two reason notions rather than only one. The general idea is that the properties of the object provide reason not only for a certain kind of favouring(s

In this paper, we incorporate the layered structure with low-density parity-check codes (LDPC) to develop a quasi-block diagonal LDPC space-time structure. The lower triangular structure of the parity check matrix introduces correlation between layers. In addition, each layer, as a part of the whole codeword, can be decoded while taking information from other undetected layers to improve the decod

Popular Abstract in Swedish I Sverige utförs cirka 3500 benamputationer varje år. Över 90% av alla amputationer görs på grund av kärlsjukdomar, där förträngningar i blodkärlen försämrar blodflödet med vävnadsdöd och vanligen kallbrand som följd. Det finns i huvudsak tre faktorer som ökar risken för amputation på grund av kärlsjukdom; ålder *80 år, rökning och diabetes. Om man inte tillhör någon avGeneral characteristics and outcome was evaluated in 177 consecutive patients who underwent a major amputation in a defined population. Smoking and diabetes lowered the mean amputation age. Healing failure at six months was seen in 24% of transtibial and in 11% of transfemoral amputees. Preoperative absence of gangrene and hemoglobin >120 g/L increased the risk of healing failure. Six months after

The aerosol size distribution in 11 dwellings was measured using an electrical mobility analyser (TSI 3030). Large variations in the aerosol concentration, e.g. in connection with cooking and smoking were detected both within a single dwelling and between different dwellings. A typical size distribution shows an area median diameter of 0.2 µm with a geometrical standard deviation of about 2. Varia
