We consider a problem originating both from circle coverings and badly approximable numbers in the case of dyadic diophantine approximation. For the unit circle S we give an elementary proof that the set {x is an element of S : 2(n)x >= c (mod 1) n >= 0} is a fractal set whose Hausdorff dimension depends continuously on c and is constant on intervals which form a set of Lebesgue measure 1. Hence i
The spinocerebellar systems are essential for the brain in the performance of coordinated movements, but our knowledge about the spinocerebellar interactions is very limited. Recently, several crucial pieces of information have been acquired for the spinal border cell (SBC) component of the ventral spinocerebellar tract (VSCT), as well as the effects of SBC mossy fiber activation in granule cells
Foreword to the publication.
For most Thai people, Buddhism serves as a base for explanations about life and death. This article focuses on Buddhist practices and the importance of ceremonies in the recovery process after the 2004 tsunami in Southern Thailand. The tsunami had devastating consequences for most people in the coastal regions. First, through the loss of life, and second, through the damage to and loss of houses,
We have investigated the oxygen induced structures of the Pd(1 1 0) surface in the pressure range of 10(-5)-10(-3) mbar of oxygen, at a sample temperature of around 300 degrees C. These structures, denoted as "(7 x root 3)" and "(9 x root 3)", are studied in detail by the use of a combination of low-energy electron diffraction, scanning tunneling microscopy, high-resolution core level spectroscopy
The Vasalemma Formation (early Katian, Late Ordovician) of northern Estonia consists of a succession of biodetrital grainstones up to 15 m thick with numerous intercalated reef bodies, which reach diameters of more than 50 m. Four dominant facies types are distinguished within the reef core limestones: (1) a bryozoan framestone-bindstone, (2) an echinoderm bindstone, (3) a receptaculitid-bryozoan-
Stretch of vascular smooth muscle stimulates growth and proliferation as well as contraction and expression of contractile/cytoskeletal proteins, all of which are also regulated by calcium-dependent signals. We studied the role of the calcium- and integrin-activated proline-rich tyrosine kinase 2 (PYK2) in stretch-induced responses of the rat portal vein loaded by a hanging weight ex vivo. PYK2 ph
Aim: To investigate the therapeutic effects of fluorouracil (5-Fu) and octreotide (Oct) continuous regional arterial infusion (CRAI,) alone or in combination, was administered in a canine model of severe acute pancreatitis (SAP). Materials and Methods: The animals were divided into five groups; group A (Sham), group B (SAP), group C (SAP and 5-Fu), group D (SAP and Oct), and group E (SAP and 5-Fu
We used molecular dynamics simulation to model the effect of urea and thiourea on the solvent quality of aqueous solutions with respect to cellulose. A model system consisting of a periodically replicated cellulose molecule of effectively infinite degree of polymerization immersed in aqueous (thio-)urea solution was considered. Kirkwood-Buff theory, which relates the pair distribution functions to
The 24th of April 2015 will mark the centennial commemoration of the Armenian genocide and is expected to be a worldwide ceremony. Hundred years will have passed since the start of the state orchestrated massacres and deportations in 1915 which emptied the majority of historical Armenia from its native population. A century has passed, but ironically, the Armenian genocide seems to become more top
The development of strategies for dissolution and regeneration of cellulose constitutes an increasingly active research field due to the direct relevance for many production processes and applications. A wide variety of suitable solvents for cellulose are already available. However, cellulose solvents are of highly different nature reflecting the great challenges in the understanding of the subtle
Depressive symptoms are potential outcomes of poorly functioning work environments. Such symptoms are frequent and cause considerable suffering for the employees as well as financial loss for the employers. Accordingly good prospective studies of psychosocial working conditions and depressive symptoms are valuable. Scientific reviews of such studies have pointed at methodological difficulties but
Decreased insulin sensitivity, also referred to as insulin resistance (IR), is a fundamental abnormality in patients with type 2 diabetes and a risk factor for cardiovascular disease. While IR predisposition is heritable, the genetic basis remains largely unknown. The GENEticS of Insulin Sensitivity consortium conducted a genome-wide association study (GWAS) for direct measures of insulin sensitiv
The structural and optical properties of three different kinds of GaAs nanowires with 100% zinc-blende structure and with an average of 30% and 70% wurtzite are presented. A variety of shorter and longer segments of zinc-blende or wurtzite crystal phases are observed by transmission electron microscopy in the nanowires. Sharp photoluminescence lines are observed with emission energies tuned from 1
Because of its existential character, organ transplantation is strongly connected to a person's view of life. This article describes how participants in a focus group use religious elements in decision-making on transplantation medicine in four European countries. Further these findings are related to two influential theologians: James Gustafson and Paul Ramsey, and their thinking on the role of r
This dissertation explores how son preference is constructed and renegotiated in light of social change in the People’s Republic of China (PRC). Based on secondary sources and interviews with women and men in rural Anhui Province as well as key informants, it addresses son preference from conceptual, methodological, empirical and ideological perspectives. The analysis centres around son preference
Nocturnal hawkmoths are known for impressive visually guided behaviours in dim light, such as hovering while feeding from nectar-bearing flowers. This requires tight visual feedback to estimate and counter relative motion. Discrimination of low velocities, as required for stable hovering flight, is fundamentally limited by spatial resolution, yet in the evolution of eyes for nocturnal vision, main
Software development companies operating in market-driven domains need to deliver new and appealing software products at an increasing rate in order to stay competitive. This requires fast and efficient development of software for which the requirements are based on ever-changing market demands. Agile development claims to achieve increased development efficiency by performing the requirements eng
