The PHENIX experiment at RHIC has observed a large enhancement of baryon and anti-baryon production at p(T) approximate to 2-5 GeV/c, compared to expectations from jet fragmentation. While a number of theoretical interpretations of the data are available, there is not yet a definitive answer to the "baryon puzzle". We investigate the centrality dependence of phi-meson production at mid-rapidity in
The cycle of waterborne methylmercury (meHg) in Little Rock Lake is characterized by a period of accumulation during summertime (when the lake is warm and open to the atmosphere) and a period of decline during winter (when the lake is scaled by ice). We followed this cycle for 16 yr. during which time the lake was acidified with H,SO., and then allowed to recover naturally as part of a long-term f
The influence of the Bay of Bothnia sea level on the water stages in a series of interconnected lakes near the city of Lulea in Sweden is studied. Future conditions as a consequence of land elevation and channel improvements are simulated using a mathematical model. It is found that due to landlift the lake system will be divided into two lake systems. The upper lakes will turn to true lakes exper
A survey of the theory of propagation of transient transverse electromagnetic waves in temporally dispersive, bi-isotropic slabs is given, and a novel wave splitting, which completely separates right-going and left-going waves in the dispersive medium, is proposed. The new approach leads to a simple scattering relation in terms of wave propagators and single-interface scattering operators only. Th
Many bird species host several lineages of apicomplexan blood parasites (Protista spp., Haemosporida spp.), some of which are shared across different host species. To understand such complex systems, it is essential to consider the fact that different lineages, species, and families of parasites can occur in the same population, as well as in the same individual bird, and that these parasites may
With increasing age, human skeletal muscles gradually decrease in volume, mainly due to a reduced number of motor units and muscle fibers, and a reduced size of type 2 fibers. As a result, progressive weakening and impaired mobility occur. High-resistance strength training is beneficial, even in the very old, and could possibly reverse some of the detrimental effects of age-related weakness. The i
We present the LDCMC program implementing the Linked Dipole Chain model for deeply inelastic ep scattering within the framework of the Ariadne event generator.
The article discusses different approaches to Gerhard Richter's use of surface in his paintings.
Objective To assess intraobserver and interobserver variability in ovarian volume and gray-scale and color flow index measurements using transvaginal, three-dimensional, power Doppler ultrasonography. Methods Eleven women (22 ovaries) were examined on day 8 of controlled ovarian hyperstimulation therapy, which was part of their in vitro fertilization treatment protocol. The patients were examined
The aim of this study is to describe how ”drama in training” is experienced by student nurses and nurse tutors as well as to describe whether the students feel that there is a connection between their participation in drama, their personal development and their own preparation for their future profession. The study´s starting point has been that the students need support with regard to their perso
The point of departure for See and Seen text, website and exhibition) is the conventions of the Ideal Landscapes painted in Rome during the 17th century by artists such as Claude Lorrain and Nicolas Poussin. In 18th century England this translated into a particular gaze that became the fashion for how, and the parameters within which, the landscape was to be seen and that subsequently gave rise to
CCAAT/enhancer binding protein (C/EBP)alpha is a myeloid-specific transcription factor that couples lineage commitment to terminal differentiation and cell cycle arrest, and is found mutated in 9% of patients who have acute myeloid leukemia (AML). We previously showed that mutations which dissociate the ability of C/EBP alpha to block cell cycle progression through E2F inhibition from its function
BACKGROUND: The 30-item disabilities of the arm, shoulder and hand (DASH) questionnaire is increasingly used in clinical research involving upper extremity musculoskeletal disorders. From the original DASH a shorter version, the 11-item QuickDASH, has been developed. Little is known about the discriminant ability of score changes for the QuickDASH compared to the DASH. The aim of this study was to
Assessment of the fire behaviour of sandwich panels is continuously under discussion. The fire behaviour of these panels is a combination of material characteristics such as the core material and mechanical behaviour of the panels such as joints, dilations etc. The use of small or intermediate scale tests can be questioned for such types of products. Within the proposed European product standard
Comment rendre compte du développement de l’accord sujet-verbe chez des apprenants adultes L2? Nous voulons montrer le caractère extrèmement lent et graduel de l’accord sujet-verb en français parlé, un développement qui nous semble compatible avec la fréquence des formes/fonctions en question dans l’input.
An analytical procedure based on microwave-assisted extraction (MAE) and standard addition was applied for the determination of banned azo dyes in bovine, sheep, and goat leather. Standard addition at four different concentration levels was performed using azo dyes, dissolved either in methanol or water. All dyes were determined indirectly by measuring their corresponding harmful aromatic amines,
The inhibitory innervation of guinea-pig urethral smooth muscle was investigated histochemically and functionally. The distribution of immunoreactivities to haem oxygenases (HO), neuronal NO synthase (nNOS), and vasoactive intestinal polypeptide (VIP) was studied, and the functional effects of the corresponding putative transmitters, CO, NO, and VIP, were assessed. HO-2 immunoreactivity was found
This article aims to illuminate the complexities involved in efforts to influence China's energy future. It brings forth three observations. First: China's authoritarian appearance is deceptive. Second: learning about concealed but pivotal actors and their motivations is not easy but important. Third: technology diffusion is obstructed by differences in expectations. Three summarising messages con
