We have shown in a computational model that a poor memory for context could result in some of the behaviors associated with ADHD, which is well in line with the dynamic developmental theory. Given the important role of context in extinction, a weaker context due to a steeper delay-of-reinforcement gradient would result in impaired inhibition.

In the rat eye, intracameral injections of substance P in doses of 10-30 pmol caused a maximal long-lasting miosis and a leakage of plasma proteins into the aqueous humor, indicating a breakdown of the blood-aqueous barrier. Neurokinin A seemed equipotent to SP, but calcitonin-gene-related peptide (CGRP) (17 pmol) caused neither miosis nor protein leakage into the aqueous humor. The same result wa

Popular Abstract in Swedish Syftet med denna avhandling är att undersöka varför och hur skogsbruk införs i Sverige under 1800-talet och vilka konsekvenser det har under perioden. Med skogsbruk avses den systematiska odling av högskog som sprids från Tyskland från 1700-talets slut. De konsekvenser som avses är de naturförändringar och de sociala konflikter som skogsbruket medför liksom de nya värdeThe aim of this dissertation is to investigate how and why silviculture was introduced in Sweden in the nineteenth century and the consequences this introduction had during the same period. The term silviculture refers to the systematic cultivation of high forest, a method that spread from Germany at the end of the eighteenth century. The consequences referred to are the changes in nature and the

A nonlinear 3D finite element model and a theoretical parameter study in relation to glued-in rods for timber structures are presented. A strain-softening crack band model was used to characterise the behaviour of the adhesive layer between the rod and the wood. The model is general in the sense that it bridges the gap between the theory of an ideal plastic bondline and the theory of linear elasti

Seventy standardized ringing sessions were carried out from April 1997 to August 2000 in a reedbed in Ria de Aveiro at Salreu, Portugal. The variation in the abundance of the common species is described as well as some aspects of their weight dynamics. Both, number of birds and species were higher during summer and autumn, when passage migrants occur and the number of juveniles is high. The pre-br

The author (professor of Scandinavian linguistics, *1934, living in Lund or nearby) compares his own dialect with that of his mother (house-wife, *1912, living nearly all her life 15 kilometers outside Kalmar). Interestingly, he found very few differences. The article discusses why.

En ny modell som beskriver samspelet mellan de olika materialen i ett golv lades fram på Chalmers i december 1998. I artikeln sammanfattas de olika delarna i modellen.

Objectives: To examine if obesity status and socio-economic and lifestyle factors are associated with self-reported past food habit change, and also whether the level of obesity depends on the reason for change. Design: Cross-sectional analysis within the Malmo Diet and Cancer (MDC) study using data from the baseline examination and the extensive socio-economic and lifestyle questionnaire includin

Three new species belonging to Hieracium sect. Hieracium, viz. H. argentarium, H. irmae and H. mucrodentatum, are described from the Swedish province of Värmland. In addition, H. acidolepis is described anew to accommodate the taxon hitherto known as H. acidotum (Dahlst.) Dahlst., because the type specimen (from Värmland) for that name has been shown to belong to a different species.

Isometric force, glycogen phosphorylase activity and lactate production were measured under conditions known to alter intracellular Ca2+ and cAMP to assess the role of these messengers in the coordination of metabolism with contractility in rat portal vein. Total phosphorylase (a + b) activity, was independent of treatment. The activity ratio phosphorylase activity ratio in the presence of isoprot

Views and proposals on housing improvement and social participation in Latin America have gone through changes in the last decades. These changes are noteworthy. In general, the population living in settlements scheduled to be upgraded, and the people target for participatory action, did not have much say in policy making. Housing improvement and social participation issues are linked to the Law o

Denna rapport är en bearbetning av de generella checklistor som presenteras i Fuktdimensionering med generell checklista - Tak-, Ytterväggs- och grundkonstruktioner med anslutningsdetaljer, TVBH 7164.

Leukotrienes (LTs) and prostaglandins (PGs) are metabolites of arachidonic acid that play major roles in various inflammatory conditions. The release of these mediators, by cells recruited to or present at the site of inflammation, modulate/influence the magnitude of the inflammatory response. A better understanding of eicosanoids and how their receptors trigger intracellular signaling during infl
