The cholinergic hypothesis of geriatric memory dysfunction suggests that the learning and memory deficits representing the cardinal symptoms of dementia in the aged and in patients suffering from Alzheimer's disease may be attributable to a decline in the function of the cholinergic projection systems of the basal forebrain. Although many studies have addressed the issue of a causal relationship b

A comparison of the sequence of the subunit of human alpha 2-macroglobulin (alpha 2M; 1451 amino acid residues) with that of murine complement component pro-C3 (1639 amino acid residues) reveals eight extended regions of sequence similarity. These regions contain between 19% and 31% identically placed residues and account for 75% and 67%, respectively, of the polypeptide chains of alpha 2M and pro

In this paper we describe a formalism for generating exclusive final states in diffractive excitation, based on the optical analogy where diffraction is fully determined by the absorption into inelastic channels. The formalism is based on the Good--Walker formalism for diffractive excitation, and it is assumed that the virtual parton cascades represent the diffractive eigenstates defined by a defi

Popular Abstract in Swedish Denna avhandling bygger på ett studium av romerska glaskärl funna på icke-romerska/inhemska fyndorter — huvudsakligen tillhörande den romerska järnåldern (0–400 e.Kr.) — bortom Hadrianus mur i norra Britannien. Romerska glaskärl har påträffats på inalles 60 fyndorter, varav en stor del utgörs av bosättningar av skilda slag, och endast en liten del härrör från gravar. SoThis thesis is based on a study of Roman glass vessels found on non-Roman/native sites - chiefly of Roman Iron Age date (AD 0-400) - beyond Hadrian’s Wall in northern Britain. Roman glass vessels have been discovered on 60 sites in total, the majority of which are settlements of various types, and only a minor part are graves. As a consequence of this, the greater part of the material is strongly

It is shown that, for short and moderate relative tailbiting lengths and high signal-to-noise ratios, systematic feedback encoders have better bit error performance than nonsystematic feedforward encoders. Conditions for when tailbiting will fail are given and it is described how the encoder starting state can be obtained for feedback encoders in both controller and observer canonical form

Estetisering av platser i syfte att genom affärsutveckling skapa mervärde har blivit en allt viktigare syssla för lokala entreprenörer inom turistbranschen. Genom att ge en plats en särskild aura lockas investerare att investera, människor att bosätta sig där och fler besökare att komma (Löfgren 2005). Turismen kan ses som ett praktiskt tillägnande av litteraturen och filmen, en läsakt som blir fy

The objectives of this activity were to propose a number of alternative HMI solutions (visual, auditory and haptic) for the concept of Safe Speed and Safe Distance and to carry out a pre-screening procedure with a number of test persons in order to give recommendations for the alternative building elements of the SASPENCE “warning-package” consisting of the combination of these modes to be tested

In industries like high-tech and automotive, increasingly more of the product value delivered to the customer is based on a combination of hardware (HW) and software (SW), where SW handles much of the differentiation of capacity and features. The “logistics process” of SW, especially when it merges with HW along the process, has so far been little studied but a problem noticed is the difficulties
