We present a novel method for monitoring isothermal lipid hydration using a sorption microcalorimeter. A measuring cell of the double-twin calorimeter consists of two vessels connected by a stainless steel tube. The upper vessel contains pure water, and the bottom vessel is loaded with the lipid sample. This calorimeter allows for simultaneous measurement of the partial molar enthalpy and the chem

Here we explore two new tree-ring parameters, derivedfrom measurements of wood density and blue intensity(BI). The new proxies show an increase in the interannualsummer temperature signal compared to establishedproxies, and present the potential to improve long-term performance.At high latitudes, where tree growth is mainlylimited by low temperatures, radiodensitometric measurementsof wood density

BACKGROUND Surgical site infections (SSIs) after dermatologic surgery cause pain, prolong healing, result in unaesthetic complications, and lead to excessive use of antibiotics. The pathogenesis of wound infections is complex and is dependent on bacterial load and diversity, among several factors. OBJECTIVE To investigate bacterial dynamics at dermatosurgical sites at different time intervals and

The damage caused by a dramatic worldwide increase in so-called natural disasters is staggering, with the poor in developing countries being most at risk. This paper analyses: (a) the key variables and their causal relations that underlie the complex system of risk and disaster occurrence in slums; (b) the impacts of disasters on slums; (c) the strategies used by local people to cope with risk and

Popular Abstract in Swedish Genetisk påverkan i ledgångsreumatism Ett väl fungerande immunsystem är en förutsättning för kroppens kamp mot diverse sjukdomar orsakade av t ex virus och bakterier. En grundläggande egenskap hos immunsystemet är dess förmåga att skilja på vad som är kroppens egna celler och molekyler och vad som är främmande. Ibland fungerar inte denna diskriminering som den ska och In this thesis the role of major histocompatibility complex (Mhc) class II molecules in development of autoimmune disease such as rheumatoid arthritis (RA), was studied. By combining an experimental model for RA, collagen type II induced arthritis (CIA), with molecular biology methods the importance of polymorphism in Mhc class II genes for disease development was investigated. The Mhc region con

Phototoxicity occurs when a substance is toxic only under the action of light, and can, depending on the mechanism of toxic action, be divided into type I and type II phototoxicity. Other types are sometimes recongnized, and sometimes toxicity occurs through more than one mechanism. Plants often use phototoxins for their defense. They may be harmful to man, but also exploited for medical treatment

In this talk we show some potential applications of a pair of conventional double positive (DPS) and single negative (SNG) metamaterial blocks for specific patch antennas. We propose two designs. One is a 900- and 1800-MHz dual-band rectangular patch antenna filled with a pair of juxtaposed DPS and mu-negative (MNG) metamaterial blocks. With proper constitutive parameters and filling ratio of the

The paper presents a feedback scheduling mechanism in the context of co-design of the scheduler and the control tasks. We are particularly interested in controllers where the execution time may change abruptly between different modes, such as in hybrid controllers. The proposed solution attempts to keep the CPU utilization at a high level, avoid overload, and distribute the computing resources eve

Spontaneous data from Swedish are presented which suggest that ‘creaky voice’ associated with the filler EH ‘UH’ is related to the realization of the speaker attitude ‘uncertainty’ in the sense of ‘indecisiveness’ as regards the optimal way to linguistically code referents and predicates. It is suggested that creaky fillers express a certain degree of speaker indecisiveness as regards the most rel

The reassignment technique is used to increase the localization for signals that have closely located time-frequency components. For Gaussian components the reassignment based on an optimal (matched) window spectrogram will result in a single point where all mass is located. For non-optimal windows, the reassignment procedure can be optimally rescaled to fulfill the single point mass location. Non

The humoral immune response to a T cell dependent protein antigen will over time generate antibodies with an increased affinity to the antigen. This is due to a process known as affinity maturation and proceeds in a, for this purpose, well designed micro-milieu within secondary lymphoid organs known as germinal centres. The increase in affinity of an antibody in, e.g. mouse and man is due mainly t

AIMS: The sural nerve is the commonest peripheral nerve biopsied to help in the diagnosis of peripheral neuropathy of unknown cause. However, associated complications limit its use. The aim was, as an alternative, to asses biopsy of the terminal branch of the posterior interosseous nerve (PIN) in the forearm. METHODS: PIN pathology was morphometrically quantified in 10 male patients with Type 2 di

Artikeln diskuterar en väsentligen nordamerikansk tanketradition som explicit eller implicit framställer den centrala antika filosofiska frågan – ”hur bör jag leva?” – som sin frågehorisont, och som gör det såväl teoretiskt, empiriskt som normativt. Det handlar om sociologer och andra samhällsvetare, men också om litteraturvetare och kulturkritiker, essäister och skönlitterära författare. ArtikelnThe article describes and analyses an essentially American intellectual tradition which explicitly or implicitly poses the central question of Hellenistic and Roman philosophy – ”how should I live?” – as its main theme and concern, and which discusses the matter theoretically, empirically, and normatively. The tradition includes sociologists and other social scientists, but also cultural theorists

We present the results of 3D high-resolution calculations of the last inspiral stages and the final coalescence of neutron star binary systems. The equations of hydrodynamics are solved using the smoothed particle hydrodynamics method with up to 106 particles. Using Newtonian gravity, but adding the forces emerging from the emission of gravitational waves, we focus on the impact of microphysics on
