Making Radical Cations Live Longer

The acid-catalyzed rearrangement of 1,4,5,8-tetramethylnaphthalene was used to determine the acidity of media used for EPR spectral studies of radical cations. The radical cations of methyl-substituted naphthalenes were shown to undergo dimerization reactions. The apparent persistency of the radical cation of hexamethylbenzene was due to the slow oxidation when thallium(III) trifluoroacetate was

Postnatal Development of Spinal Nociceptive Pathways: Evidence for Involvement of Experience-Dependent Mechanisms

Popular Abstract in Swedish Smärta kan betraktas som en varningssignal för annalkande eller redan inträffad vävnadsskada och har därigenom en uppenbar skyddsfunktion. Förmågan att genom snabba förändringar av pågående motorik avvärja en skadlig stimulering återfinns både hos människa och hos mer enkelt uppbyggda organismer långt ned på den fylogenetiska stegen. Den snabba bortdragning av handen soThe adult organization and postnatal development of the nociceptive withdrawal reflexes (NWR) of single hindlimb muscles were examined in decerebrate spinal rats using electromyography. In adult rats, NWR were found to perform highly organized sensorimotor transformations, with single muscles receiving excitatory cutaneous input from specific receptive fields (RF) whose distribution of sensitivity

Value uncertainty and value instability in decision-making

The purpose of this paper is to clarify the role of value uncertainty and value instability in decision-making that concerns morally controversial issues. Value uncertainty and value instability are distinguished from moral uncertainty, and several types of value uncertainty and value instability are defined and discussed. The relations between value uncertainty and value instability are explored,

Fluvial transport and risk of mercury in a gold mining area

My thesis is part of an overall environmental program evaluating the environmental and human health stress in areas of Nicaragua affected by anthropogenic emission of metals and man-made organic substances. I examine the fluvial transport of mercury contextually associated with the extent of the contamination and the observed human and environmental stress in a gold mining area. Field measurements

Effective degree-of-freedom of a compact six-port MIMO antenna

In this paper, we confirm that angle and polarization diversities are indeed the dominant diversity mechanisms of a recently proposed compact six-port MIMO antenna array, as it exhibits similar effective degree-of-freedom (EDOF) performance as that of the ideal array with co-located antenna elements evaluated in propagation scenarios with different angular spreads. Furthermore, the same approach c

En gourmetmiddags estetiska komposition

I denna artikel används Kenneth Burkes teori om estetisk och retorisk form, från Counter-Statement (först publiserad 1931), för att analysera hur stjärnkocken Mathias Dahlgren kreear en gourmetmåltid. Samtidigt framgår att Burkes teori förmår att hantera problem som dominerande teorier om tjänstekvalitet har problem med.

A Study of the Interaction between the HOO radical and some small Molecules

The HOO radical is a key intermediate in the atmosphere and is involved in a large number of reactions, including ozone loss cycles in the stratosphere and oxidation processes in the troposphere. This theses is a study of the HOO radical and its interactions with a number of small molecules that are present in the atmosphere. The HOO complexes were formed on the surface of growing argon matrices

User related assessment of Continuous Support & Curve Speed Control (CRF)

The aim of the user related assessment is to evaluate the effects on driver behaviour, reactions to and acceptance of the driver assistance system: Continuous Support (CS) function developed by CRF within the framework of SECONDS subproject. The CS function continuously evaluates the status of the host vehicle as well as the surrounding traffic based on the information of the on-board sensors. Whe

Comparative Assessment of Fuel-Based Systems for Space Heating

Replacing fossil fuels by biofuels and increasing energy efficiency are often considered to be options for reducing the net emission of greenhouse gases. This thesis presents the results of analyses of energy efficiency, emission and cost of whole energy system chains, from the natural resource to the end user when heating detached houses in a Swedish context. External costs and taxes of the energ
