Donor-acceptor (D-A) copolymers typically show two absorption peaks in the visible region, flanking a valley region of limited absorptivity. One strategy for more panchromatic light harvesting is to incorporate side-groups orthogonal to the polymer backbone, which enable 2D π conjugation and can give rise to additional absorption peaks. Here we design and synthesize two D-A polymers which both car

In order to understand how visions and narratives about the Internet are articulated, negotiated, and circulated in China, one needs to address and unpack a number of interrelated issues. It is important to map who has the possibility to articulate visions on the Internet in China, who is actually doing it and why, what having a ‘vision’ actually means, and which platforms different individuals an

BACKGROUND: This prospective study compares results of infrainguinal revascularisation with autologous vein in diabetic and non-diabetic populations.PATIENTS AND METHODS: 101 patients (diabetics (A) n = 50 and non-diabetics (B) n = 51) were operated upon with an in situ saphenous vein bypass to the popliteal artery below knee or to crural arteries, due to critical ischemia. Data on operative detai

Solid-state sodium ion batteries are frequently referred to as the most promising technology for next-generation energy storage applications. However, developing a suitable solid electrolyte with high ionic conductivity, excellent electrolyte–electrode interfaces, and a wide electrochemical stability window, remains a major challenge. Although solid-polymer electrolytes have attracted great intere

Written exposure therapy är en skriftlig terapiform avsedd att behandla posttraumatiskt stressyndrom. I denna litteraturöversikt granskades kvaliteten på RCT-studier som gjorts på WET, samt de kliniska implikationerna av det som framkommit i studierna. Litteratursökning resulterade i sex artiklar och en avhandling. Kvaliteten på studierna granskades genom skattning med hjälp av Cochrane Risk Written exposure therapy is a written form of therapy intended to treat post- traumatic stress disorder. In this literature review, the quality of RCT studies conducted on WET was examined, as well as the clinical implications of what emerged in the studies. Literature search resulted in six articles and one dissertation. The quality of the studies was reviewed by using the Cochrane Risk of Bias T

The purpose of this study was to examine how Romanian social workers, working with LGBT-people, experience their work situation and the conditions for their work. The questions at issue were; How do the social workers describe their work and the conditions for conducting this work? What kind of attitudes do they meet, regarding their work, from the surrounding society? What kinds of strategies are

We propose that CDCL SAT solver heuristics such as restarts and clause database management can be analysed by studying the resolution proofs produced by the solvers, and by trimming these proofs to extract the clauses actually used to reach the final conclusion. We find that for non-adaptive Luby restarts higher frequency makes both untrimmed and trimmed proofs smaller, while adaptive restarts bas

Popular Abstract in Swedish Elektrolyter är ämnen som sönderdelas i ett lösningsmedel och därvid ger upphov till positivt och negativt laddade joner. De starka elektrostatiska krafter i lösningen som detta i sin tur orsakar är typiska för elektrolytlösningar. Redan vid små tillsatser av en elektrolyt till ett lösningsmedel kan lösningens egenskaper förändras kraftigt. Lösningar av elektrolyter speA thermodynamic model for electrolyte solutions has been derived for binary and multicomponent solutions up to very high molalities. The model was extensively tested on 163 binary aqueous electrolyte systems up to very high molalities, and the results show that the model represents mean ionic activity coefficients and osmotic coefficients very accurately. The model parameters vary significantly be

Concrete hardens as a result of chemical reactions between water and cement. Cement is a hydraulic binder, in the reaction the cement binds water-molecules. This is an exoterm process, heat is produced during the reactions. How fast this process proceeds is much depending of the temperature. The amount of heat produced during the hardening of the concrete is also depending on the thickness of the

A variational approach, based on a discrete representation of the chain, is used to calculate free energy and conformational properties in polyelectrolytes. The true bond and Coulomb potentials are approximated by a trial isotropic harmonic energy containing force constants between all monomer-pairs as variational parameters. By a judicious choice of representation and the use of incremental matri

When costumers look for a robot for their factory two things are important. The robot should be as efficient as possible, but still be cheap. In order to make the robot efficient the robot-controller has to know the dynamics of the robot and its limits. Based on these it can then generate a time-optimal plan (trajectory) for each movement. The standard way of generating a time-optimal trajectory w

In this report heat quantity measuring and temperature regulation of smaller heating networks have been studied. At lower flows, as well as at lower difference temperatures, the accuracy of the measurement is very low. Today's control of a heating plant endeavour to let the temperature of the water into the heating network follow the heat requirement. This control strategy leads to small heat
