Branched-linear polyion complexes investigated by Monte Carlo simulations

Complexes formed by one charged and branched copolymer with an oppositely charged and linear polyion have been investigated by Monte Carlo simulations. A coarse-grained description has been used, in which the main chain of the branched polyion and the linear polyion possess the same absolute charge and charge density. The spatial extension and other structural properties, such as bond-angle orient

Characteristics of Androgen Deficiency in Late-Onset Hypogonadism: Results from the European Male Aging Study (EMAS).

Context:Late-onset hypogonadism (LOH) has been defined as a syndrome in middle-aged and elderly men reporting symptoms in the presence of low testosterone (T). Objective:The objective of the study was to seek objective biochemical and end-organ evidence of androgen deficiency in men classified as having LOH according to our previously published criteria. Design, Setting, and Participants:The des

Validity, reliability, and responsiveness of a self-reported foot and ankle score (SEFAS)

Background and purpose A questionnaire was introduced by the New Zealand Arthroplasty Registry for use when evaluating the outcome of total ankle replacement surgery. We evaluated the reliability, validity, and responsiveness of the modified Swedish version of the questionnaire (SEFAS) in patients with osteoarthritis or inflammatory arthritis before and/or after their ankle was replaced or fused.

Locus Celebris : Dalby kyrka, kloster och gård aktualiserade

Locus Celebris – the Church, Monastery and Manor of Dalby actualized: An introduction to the common view on Dalby, to the research history and mediation of the place, to the international conference 24-27 April 2011 in Dalby and finally also an introduction to the conference publication.

Sociology of Law in a Digital Society - A Tweet from Global Bukowina

Is it possible to determine the Facebook Gemeinschaft or the living law of the global file sharing community? What are the social facts of twitter or the intuitive law of Chinese microbloggers? This paper argues that digitization of society, the reliance on digital networks, protocol, algorithms and completely new sets of organisational structures for social communities, have vast implications for

Numerical modelling of resolution and sensitivity of ERT in horizontal boreholes

Resistivity in horizontal boreholes can give useful detailed information about the geological conditions for construction in rock, i.e. in front of a tunnel bore machine. This paper is an attempt to identify a suitable methodology for an effective measuring routine for this type of geophysical measurements under actual construction site conditions. Prior to any measurements numerical modelling was

Chloride transport and chloride thresholdvalues-Studies on concretes and mortars with Portland cement and limestone blended cement

Reinforced concrete is one of the most widely used building materials and if it is properly designed and produced, it is an extremely durable material with a service life up to 100 years. However, under certain environmental conditions the service life of reinforced concrete structures is more limited. Deterioration of concrete structure is in most cases caused by the penetration of aggressive med

Klassikerintro : Distinktioner mellan klassisk och modern retorik

En av de verkligt stora frågorna i den samtida retorikteorin är förhållandet till det klassiska arvet. Retoriken kan sägas vara det moderämne i den humanistiska bildningstraditionen som många ämnen inom humaniora har avknoppats från, och därför är det inte lika självklart att det nya är bättre än det gamla när retorikforskare ser på sitt eget ämne. Andrea A.Lunsford är en av de ledande retorikfors

Strategic female reproductive investment in relation to male attractiveness in birds

Life-history theory predicts that individuals should adjust their reproductive effort according to the expected fitness returns on investment. Because sexually selected male traits should provide honest information about male genetic or phenotypic quality, females may invest more when paired with attractive males. However, there is substantial disagreement in the literature whether such differenti

Benchmarking the seasonal cycle of CO2 fluxes simulated by terrestrial ecosystem models

We evaluated the seasonality of CO2 fluxes simulated by nine terrestrial ecosystem models of the TRENDY project against (1) the seasonal cycle of gross primary production (GPP) and net ecosystem exchange (NEE) measured at flux tower sites over different biomes, (2) gridded monthly Model Tree Ensembles-estimated GPP (MTE-GPP) and MTE-NEE obtained by interpolating many flux tower measurements with a

How could the Viking Sun compass be used with sunstones before and after sunset? Twilight board as a new interpretation of the Uunartoq artefact fragment

Vikings routinely crossed the North Atlantic without amagnetic compass and left their mark on lands as far away as Greenland, Newfoundland and Baffin Island. Based on an eleventh-century dial fragment artefact, found at Uunartoq in Greenland, it is widely accepted that they sailed along chosen latitudes using primitive Sun compasses. Such instruments were tested on sea and proved to be efficient h

The organization of honeybee ocelli: Regional specializations and rhabdom arrangements

We have re-investigated the organization of ocelli in honeybee workers and drones. Ocellar lenses are divided into a dorsal and a ventral part by a cusp-shaped indentation. The retina is also divided, with a ventral retina looking skywards and a dorsal retina looking at the horizon. The focal plane of lenses lies behind the retina in lateral ocelli, but within the dorsal retina in the median ocell

Microphotoluminescence studies of tunable wurtzite InAs0.85P0.15 quantum dots embedded in wurtzite InP nanowires

We have investigated the effects of strong confinement in wurtzite InAs0.85P0.15 quantum dots embedded in wurtzite InP nanowires using microphotoluminescence spectroscopy. Strain-dependent k . p calculations were used to model the quantum dots, and it was found that the electron effective mass was increased by a factor of 2 and the band gap was increased by 190 meV compared to equivalent quantum d

What role for network governance in urban low carbon transitions?

Many cities around the world have taken a pioneering role in tackling climate change and they will be key players in a possible transition to a future low carbon society. However, cities are at the same time constrained and act in a world of multi-level governance where local decision makers are dependent on both higher political levels and other actors in society. In this situation network govern

Some comments on the substituted judgement standard.

On a traditional interpretation of the substituted judgement standard (SJS) a person who makes treatment decisions on behalf of a non-competent patient (e.g. concerning euthanasia) ought to decide as the patient would have decided had she been competent. I propose an alternative interpretation of SJS in which the surrogate is required to infer what the patient actually thought about these end-of-l

Asymmetric Cooperation among Wireless Relays with Linear Precoding

Wireless relays extend coverage, improve spectral efficiency, and enhance reliability and rates of wireless cellular communication systems. In this work, we introduce the fundamental notion of asymmetric cooperation among cooperating relays in cellular downlinks - different relays are party to different but overlapping knowledge about the messages transmitted from the base station. We argue that a
