Multiconfiguration second-order perturbation theory, including relativistic effects and spin-orbit coupling, has been employed to investigate the nature of the chemical bonding in the ground state of Tc-2 and Re-2. The Tc-2 ground state is found to be a 0(g)(+) state, with an effective bond order (EBO) of 4.4, and a dissociation energy of 3.25 eV. The Re-2 ground state is a 1(g) state, with EBO =

In this paper we describe how we can do camera resectioning from a box with unknown dimensions, i.e. determine the camera model, assuming that image pixels are square. This assumption is equivalent to assuming that the camera as an aspect ratio of one and zero skew, and holds for most - if not all - digital cameras. Our proposed method works by first deriving 9 linear constraints on the projective

Inflammation caused by the accumulation of oxidized low-density lipoprotein (oxLDL) in the arterial wall is a key factor in the development of atherosclerosis. Accumulating evidence suggests that adaptive immune responses to oxLDL are of major importance in regulating the inflammatory response, and that humoral immunity largely has a protective effect in this process. This concept is supported by

During complement activation the pro-inflammatory anaphylatoxins C3a and C5a are generated, which interact with the C3a receptor and C5a receptor (CD88), respectively. C5a and its degradation product C5a-des-Arg(74) also bind to the C5a receptor-like 2 (C5L2). C3a and C3a-des-Arg(77), also called acylation-stimulating protein, augment triglyceride synthesis and glucose uptake in adipocytes and ski

The effect of a study day on the subject of pain for nurses working at the thorax surgery department The aims of this investigation were: to describe patients' evaluation of pain and the treatment of pain after thorax surgery via sternotomy; to repeat the evaluation with another group of patients following a study day for nurses, featuring pain and pain treatment; and to examine whether the study

Complexation of o-phthalate (1,2-benzenedicarboxylate) and competitive complexation of phosphate and phthalate at the goethite-water interface have been studied in 0.1 M Na(NO3) media at 298.2 K within the range 3.0 < -log [H+] < 8.5. Equilibrium measurements were performed as potentiometric titrations supplemented with spectrophotometric phosphate and phthalate analyses. The binary and ternary ch

Context: When using the Case Method in teaching situations, problem-solving is emphasized and taught, in order to acquire the skills and later be able to apply them in new situations. The basis of the learning process is the students’ own activity in the situation and is built on critical appraisal and discussion. Objectives: To explain what the Case Method is, what it is not and to describe when

Organ-specific lymphocyte homing is dependent on the expression of tissue-specific homing receptors and selected chemokine receptors. During the effector phase of an immune response, IgA and IgG antibody-secreting cells (ASC) are differently distributed in the body. Still, B cell expression of L-selectin and the mucosal homing receptor integrin alpha 4 beta 7 is not related to the isotype produced

In this paper, the inverse scattering problem of amultilayer structure is analysed with the Fisher information matrix and the Cramer-Rao lower bound (CRLB). The CRLB quantifies the ill-posedness of the inverse scattering problem in terms of resolution versus estimation accuracy based on the observation of noisy data. The limit for feasible inversion is identified by an asymptotic eigenvalue analys

The capillary filtration coefficient (CFC) is assumed to reflect both microvascular hydraulic conductivity and the number of perfused capillaries at a given moment (precapillary sphincter activity). Estimation of hydraulic conductivity in vivo with the CFC method has therefore been performed under conditions of unchanged vascular tone and metabolic influence. There are studies, however, that did n

Objective. To assess the efficacy of low-dose prednisolone on joint damage and disease activity in patients with early rheumatoid arthritis (RA). Methods. At the start of their initial treatment with a disease-modifying antirheumatic drug (DMARD), patients with early (duration

BACKGROUND: The sperm chromatin structure assay (SCSA) provides an objective assessment of sperm chromatin integrity, which is essential for normal sperm function. SCSA is valuable as a fertility marker in epidemiological studies and in the clinical situation. Little is known about the impact of testicular and post-testicular function on SCSA parameters. METHODS: Ejaculates from 278 military consc

The growth of the literature on eating disorders during four decades is described, especially the development of literature on bulimia. The study is based on a database, ED40, that contains more than 14,000 references to articles on ED from 1960 to 1999. The references were imported from Medline(R) and PsycINFO(R). A broad search method included articles on the physiology of hunger and satiety. Th
