The short paper describes and exemplifeis specific design and research considerations in developing efficient and engaging pedagogical agents that not only capitalize on technological advancements but are also sensitive to cognitive, emotional, and social aspects while valuing and maintaining ecological validity in an educational context
Prostate-specific antigen (PSA) is a glycoprotein produced by the prostate gland. It occurs in several molecular forms in the blood and assays have been developed to measure free PSA and PSA in complex with alpha-1-antichymotrypsin (PSA-ACT). Higher proportions of free PSA (PSA-F/T) in blood are found in subjects with benign prostatic hyperplasia (BPH) as compared to cancer patients. Utilizing imm
The physics program in Hall A at Jefferson Lab commenced in the summer of 1997 with a detailed investigation of the 16O(e,ep) reaction in quasielastic, constant (q,) kinematics at Q20.8 (GeV/c)2, q1 GeV/c, and 445 MeV. Use of a self-calibrating, self-normalizing, thin-film waterfall target enabled a systematically rigorous measurement. Five-fold differential cross-section data for the removal of p
About the concept of pain in a literary context.
To be able to explore different signal types and processing techniques, apt for sediment mapping, programmable, fully digital profiling systems has been built and tested. The systema are designed to be deployed also at small water depths from small boats, without special handling equipment. The usable frequency band is 100-25000 Hz, limited to approximately 2-10 kHz depending on the projector used
Popular Abstract in Swedish Melatonin är ett hormon som produceras i, och frisätts från pinealorganet hos ryggradsdjur. Melatoninets viktigaste uppgift är att till hjärnan förmedla signalen om nattens längd, d.v.s vilken årstid det är. Produktionen och frisläppningen sker rytmiskt med den högsta nivån under natten. Melatoninet transporteras ut i kroppen via blodet och binder till särskilda mottagaMelatonin is a neurohormone which mediates photoperiodic signals from the pineal organ to the brain. GABA (g-aminobutyric acid) is the major inhibitory transmitter in the central nervous system. It has previously been suggested that functional interaction exists between central binding sites for GABA/benzodiazepines (GABAA/bzd receptors) and melatonin in the central nervous system, and that GABA a

Popular Abstract in Swedish Digital (datorbaserad) teknik för bildframställning är idag regel för samtliga moderna modaliteter i diagnostisk radiologi, såsom ultraljud, datortomografi, magnetisk resonanstomografi, scintigrafi, och digital subtraktionsangiografi. Digital bildteknik medför fördelar vid bildbearbetning, demonstration, bildkommunikation, samt arkivering. Majoriteten av undersökningarThe aims of the study were to investigate the applications of digital radiography to musculoskeletal radiology. In the first part of the research, the diagnostic accuracy of digital images as compared to film-screen radiographs was studied and the spatial resolution requirements evaluated. Using computed radiography (CR), the pathological changes included were erosions, soft tissue swelling, peri
Popular Abstract in Swedish Barksprickor på bok och gran i södra Sverige. Jag har undersökt samband mellan barksprickor, frostkänslighet och näringsstatus hos bok och gran i södra Sverige, samt om åtgärder mot markförsurning och näringsobalans i form av kalkning och vitaliseringsgödsling kan minska trädens frostkänslighet och därmed minska uppkomsten av barksprickor. Frost kan skada den inre, leStrong temperature fluctuations and pathogen attacks can cause bark lesions, visible signs of wounds in the phloem and cambium. Pathogenic insects and fungi are able to invade lesions that have not healed, further increasing the damage. The ability of the tree to withstand climatic and biotic stress can be lowered by air pollution, especially N deposition, with subsequent alterations in the soil c
Hösten 2005 intensifierades de kommunala insatserna mot brott och för trygghet i centrala Landskrona. Bakgrunden var en ökning i antalet anmälda misshandelsfall och personrån samt en medborgarundersökning som visade att Landskronaborna upplevde en stor otrygghet. I föreliggande rapport uppmärksammas delar av trygghetsinsatserna i Landskrona, särskilt Lugnt på stan-projektet och brottsförebyggarnas
