Let H be a Hilbert space of analytic functions with multiplier algebra M(H), and let M = {(f, T(1)f, ... ,T(n-1)f) : f is an element of D} be an invariant graph subspace for M(H)((n)). Here n >= 2, D subset of H is a vector-subspace, T-i : D -> H are linear transformations that commute with each multiplication operator M-phi is an element of M(H), and M is closed in H-(n). In this paper we investi

The acquisition of multispectral x-ray images and the treatment of such data are essential for understanding many devices that we encounter in everyday life. Examples include computerized tomography in hospitals and scanners at airports. X-ray devices remain impractical for undergraduate laboratories because of their considerable cost and the risk of exposure to ionizing radiation. One way to acqu

This paper introduces a novel approach to building virtual laboratories of embedded control systems using TrueTime and Easy Java Simulations. TrueTime is a freeware MATLAB/Simulink based tool commonly used to simulate embedded control systems. Easy Java Simulations is a popular authoring tool that facilitates the creation of pedagogical simulations. According to the proposed approach, authors use

Since the 1990s, vigorous debate concerning a number of key issues has taken place within the study of Chinese nationalism. Scholars have tended to differentiate between diverse types of nationalism. For example, many studies distinguish between a malign nationalism on the one hand and a benign patriotism on the other. The strongest evidence for such a distinction can be found in survey research,

The phase behavior of systems containing sodium alkyl polypropylene oxide sulfate with equimolar ratio of polypropylene oxide ammonium chloride was determined as a function of salt concentration and alkane carbon number at ambient temperature. Visual inspection as well as cross polarizers were used to detect anisotropy. Solubilization ratios for oil and brine in the middle phases were measured and

The structural characteristics of Ba-Fe double hydroxides were studied by various methods, such as scanning electron microscopy (SEM), energy dispersive X-ray (EDX) fluorescence and X-ray absorption spectroscopies (XAS). It was verified that under hyperalkaline conditions (using 10 M or 20 M NaOH solution for precipitating the substances) layered double hydroxides could be prepared and the structu

Background: Heparin Binding Protein (HBP) is released to blood circulation from activated neutrophils in bacterial infections. It is a potential inducer of vascular leakage and precludes the development of septic shock. Filgrastim induces the production of new neutrophils and modulates their bacterial-killing activity. We evaluated the effect of filgrastim on HBP -concentrations in critically ill

Chronic myeloid leukemia (CML) is caused by the transformation of a primitive hematopoietic cell by the BCR/ABL1 fusion gene that is formed through the chromosomal translocation t(9;22). CML is currently successfully treated with tyrosine kinase inhibitors targeting the ABL1 kinase domain. However, the CML stem cells are insensitive to this drug and a large fraction of patients will have relapse f

Despite efforts to stimulate the dissemination of green purchasing practices, their uptake in business and industry has so far proven limited. Reasons for the limited progress remain largely unclear. One factor explored in this thesis, is the role of information in the operationalization and dissemination of green purchasing in organizations and supply chains. The importance of knowledge and infor

Left ventricular function is altered during and after AMI. Regional function can be determined by cardiac magnetic resonance (CMR) wall thickening, and velocity encoded (VE) strain analysis. The aims of this study were to investigate how regional myocardial wall function, assessed by CMR VE-strain and regional wall thickening, changes after acute myocardial infarction, and to determine if we could

Abstract The natriuretic peptides (NPs), namely atrial natriuretic peptide (ANP) and bran natriuretic peptide (BNP), which are secreted from cardiomyocytes in response to cardiac wall stress, play a significant role in the regulation of blood pressure, intravascular volume, and cardiac remodeling. Recently, NPs emerged as hormones with metabolic actions such as inhibition of the renin-angiotensin

Large-scale pattern formation is a frequently occurring phenomenon in biological organisms, and several local interaction rules for generating such patterns have been suggested. A mechanism driven by feedback between the plant hormone auxin and its polarly localized transport mediator PINFORMED1 has been proposed as a model for phyllotactic patterns in plants. It has been shown to agree with curre
