Free radical polymerization of acrylate counterions to cationic alkyltrimethylammonium surfactant ions was performed in aqueous media. The results of the reactions were either formation, destruction or change of liquid crystalline surfactant structures, depending on the starting conditions such as the surfactant concentration, the content of inert counterions and the monomer-to-initiator ratio. Th
ASHEIM B. T., BOSCHMA R. and COOKE P. Constructing regional advantage: platform policies based on related variety and differentiated knowledge bases, Regional Studies. This paper presents a regional innovation policy model based on the idea of constructing regional advantage. This policy model brings together concepts like related variety, knowledge bases and policy platforms. Related variety atta
Film cooling effectiveness and its distribution characteristics on the gas turbine blade surface were investigated numerically. Seven rectangular ribs were located on the internal wall, and a film cooling hole had a compound inclined angle. The case with a compound angle of 45 degrees was designed to improve the lateral film cooling effectiveness on the downstream surface. The secondary flow jet f
The age specific patterns of reproduction and mortality dictated by the life history of an organism apply to potential invaders as well as resident species of an area, but whether certain life history traits are more invasive than others is an unresolved issue. We analyze a two-population system of an invading and a resident species and test the effects of age on the probability to invade when the
Hampton (1988) discovered that people are subject to overextension they categorize some things as falling under a conjunction (e.g., they categorize chess as a sport which is also a game) but not as falling under both of the corresponding conjuncts they do not categorize chess as a sport). Although subsequent literature has replicated this effect with a wider range of constructions than those orig
Abstract in French L'auteur suggére une série d'études comparatives qui traitent de la perception des pirogues à balancier, et qui visent à mieux cerner les rapports existant entre les relations sociales, la biodiversité et le développement durable dans les sociétés océaniennes des petites îles et des zones côtières exposées à de rapides mutations culturelles. Après avoir critique l'idée récente s
Three-dimensional simulations of the squealer tip on the GE-E-3 blade with eight film cooling holes were carried out. The effect of the rim width and the blowing ratio on the blade tip flow and cooling performance were revealed. Numerical simulations were performed to predict the leakage flow and the tip heat transfer with the k-epsilon model. For the squealer tip, the depth of the cavity is fixed
Several studies of meteorites show that a large disruption of an asteroid occurred ca. 470 Ma in our solar system's asteroid belt. As a consequence, a large number of meteorite impacts occurred on Earth during the following few million years. The finding and characterization, for the first time, of planar deformation features in quartz grains from rocks collected at the Middle Ordovician Hummeln s
Crohn's disease and ulcerative colitis are chronic inflammatory disorders of the gastrointestinal tract, and are collectively referred to as inflammatory bowel disease (IBD). IBD is a major cause of lifetime morbidity, has a severe impact on quality of life of patients (equivalent to that of rheumatoid arthritis, asthma, migraine, or diabetes) and constitutes a substantial economic burden to the h
A common view is that an individual delinquent can be rehabilitated in a “home” in the countryside, away from his or her original urban social ties. An ironic result is new social ties with other juvenile delinquents as they spend a considerable amount of time together at a secluded institution. Drawing on ethnographic studies in residential care institutions, this article discusses two aspects to
The removal of particulate fine fractions by a proper high-temperature cleaning device is a very important issue in the development of the biorefinery concept. Therefore, in this investigation, particles from a 100 kW(th) steam-O-2 blown circulating fluidized-bed (CFB) gasifier were sampled and characterized. The sampling was performed with a specially designed heated dilution probe downstream of
Background: Worldwide, insulin-dependent type 1 diabetes is one of the most frequently diagnosed long-term endocrine disorders found in children and the incidences of this diseased is still increasing. In Sweden the routines are, according to national guidelines, when the child is diagnosed with type 1 diabetes, the child and its family remains at the hospital for about two weeks. There is limited
We present an existence and stability theory for gravity-capillary solitary waves with constant vorticity on the surface of a body of water of finite depth. Exploiting a rotational version of the classical variational principle, we prove the existence of a minimizer of the wave energy H subject to the constraint I = 2 mu, where I is the wave momentum and 0 < mu << 1. Since H and I are both conserv
It has often been argued that money and modern monetary economies have occasioned a comprehensive rationalisation of society. Money has often been viewed as being socially destructive, while it is said that the modern monetary economy has had inescapable consequences for society, culture, and people’s daily lives. This thesis considers the introduction of computerised systems for handling digital
Background: Inherited BRCA1 and BRCA2 (BRCA1/2) mutations confer elevated breast cancer risk. Knowledge of factors that can improve breast cancer risk assessment in BRCA1/2 mutation carriers may improve personalized cancer prevention strategies. Methods: A cohort of 5,546 BRCA1 and 2,865 BRCA2 mutation carriers was used to evaluate risk of breast cancer associated with BARD1 Cys557Ser. In a second
Background: The next-to-next-to-next-to-leading order ((NLO)-L-3) nuclear energy density functional extends the standard Skyrme functional with new terms depending on higher-order derivatives of densities, introduced to gain better precision in the nuclear many-body calculations. A thorough study of the transformation properties of the functional with respect to different symmetries is required as
Bisphosphonates (BP) prevent, reduce, and delay cancer-related skeletal complications in patients, and have substantially decreased the prevalence of such events since their introduction. Today, a broad range of BP with differences in potency, efficacy, dosing, and administration as well as approved indications is available. In addition, results of clinical trials investigating the efficacy of BP
