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

Time-resolved terahertz spectroscopy was employed for the investigation of charge-transport dynamics in benzothiadiazolo-dithiophene polyfluorene ([2,7-(9,9-dioctylfluorene)-alt-S,S-(4',7'-di-2-thieny1-2',1',3'-benzothiadiazole)]) (APFO-3) polymers with various chain lengths and in its monomer form, all blended with an electron acceptor ([6,6]-phenyl-C61-butyric acid methyl ester, PCBM). Upon phot

The disaccharide trehalose stabilizes proteins against unfolding, but the underlying mechanism is not well understood. Because trehalose is preferentially excluded from the protein surface, it is of interest to examine how trehalose modifies the structure and dynamics of the solvent. From the spin relaxation rates of deuterated trehalose and (17)O-enriched water, we obtain the rotational dynamics

I den här kunskapssammanställningen tar vi upp frågor som rör hur ett förändrat klimat kan komma att påverka tillväxt och skörd av olika jordbruksgrödor, samt hur klimatet kan påverka risken för angrepp av nya och redan etablerade skadegörare och växtsjukdomar i Sverige. Ökad temperatur leder till förlängning av växtsäsongen och utrymme för produktionsökning. I takt med att klimatet blir varmare k

We propose a powerful hardware architecture for pixel shading, which enables flexible control of shading rates and automatic shading reuse between triangles in tessellated primitives. The main goal is efficient pixel shading for moderately to finely tessellated geometry, which is not handled well by current GPUs. Our method effectively decouples the cost of pixel shading from the geometric complex

We present an analysis of the colloidal dynamics of particles in a mixture of two solvents subjected to evaporation. For simplicity, only one out of the two solvents is considered to be volatile. The evaporation generates a distribution of the solvent concentration in the system. As the particles selectively interact with the solvents, their migration becomes affected by a "chemotaxis" force, caus

A changing climate is expected to have profound effects on many aspects of ectotherm biology. We report on a decade-long study of free-ranging sand lizards (Lacerta agilis), exposed to an increasing mean mating season temperature and with known operational sex ratios. We assessed year-to-year variation in sexual selection on body size and postcopulatory sperm competition and cryptic female choice.

The coordination polymer [Fe(SCN)(2)(1,2-bis(4-pyridylmethylene)hydrazine)(2)](n) [Fe(phenanthroline)(3)](2n)(ClO4)(2n)center dot n1,2-bis(4-pyridylmethylene)hydrazine center dot 4nH(2)O 1 was crystallised from a MeOH/MeCN solution and the structure consists of layered (4,4) 2D-nets with supramolecular ([Fe(phen)(3)](2)bphz)(4+) units in the pores and disordered water and perchlorate anions. The s

We compute the Hausdorff and Minkowski dimension of subsets of the symbolic space Sigma(m) ={0, ... , m-1}(N) that are invariant under multiplication by integers. The results apply to the sets {x is an element of Sigma(m): for all k, x(k)x(2k) ... x(nk) = 0}, where n >= 3. We prove that for such sets, the Hausdorff and Minkowski dimensions typically differ.

Lund University, Sweden, is the only seat of learning having Sociology of Law (hereafter SoL) at all levels in Europe. SoL was initiated in 1972 as a department at the Social Science Faculty, with professor Per Stjernquist as chair. Later on, for some 10 years, SoL was a division within the department of Sociology but from January 2006, SoL is an autonomous department at the Social Science Faculty
