Mechanics of bird flight: the power curve of a pigeon by C. J. Pennycuick.
Pathogenesis of Shiga toxin-associated hemolytic uremic syndrome
The aim of this review is to examine recent advances in experimental and clinical research relevant to the pathogenesis of diarrhea-associated hemolytic uremic syndrome with special reference to histopathologic findings, virulence factors of Shiga toxin-producing Escherichia coli, the host response, and the prothrombotic state. Despite significant advances during the past decade, the exact mechani
Stability and variability in the realism of confidence judgments over time, content domain, and gender
This study investigates the influence on the realism of confidence judgments of four different factors, the individual, the knowledge domain (crystallized and fluid intelligence), gender and cognitive style (Need-for-Cognition, NfC). Seventy-nine high-school students answered questions on word knowledge (WORD) and logical/spatial ability (DTK), both tests were administered on three occasions with
Non-surgical treatment in carpal tunnel syndrome.
The tyranny of small steps: A reoccurring behaviour in management
The Tyranny of Small Steps (TYST) behaviour has been investigated. Explained through a systemic perspective, the behaviour TYST is an unwanted change to a system through a series of small activities that may be independent from one another. These activities are small enough not to be detected by the 'surveillance' within the system, but significant enough to encroach upon the 'tolerance zone' of t
New directions for erectile dysfunction therapies.
Research in the field of erectile function and dysfunction has continued to expand rapidly. Based on the information available, some directions for future erectile dysfunction therapies can be identified. The first direction is improvement of current therapeutic principles. A second generation of orally active phosphodiesterase (PDE) inhibitors is being introduced, and further developments within
The APC-PCI complex concentration predicts outcome of aortic surgery.
Introduction: Coagulation activation may be related to complications during surgery for abdominal aortic aneurysm. The complex formed between activated protein C (APC) and the serpin, protein C inhibitor (PCI), is a sensitive indicator of the activation of blood coagulation. The purpose of the study was to establish whether the APC-PCI complex can provide information useful for the assessment of o
Antenna diversity evaluation for mobile terminals
In this paper we are focusing on the practical, engineering way of evaluating and characterizing the multi-channel antenna solutions on the mobile terminal. Two methods of calculating the parameters, describing the diversity performance, are described and the practical use of the methods in simulations and measurements are presented and evaluated. The time saving aspect of using the scattering par
Effects of mycorrhizal colonization by Paxillus involutus on uptake of Ca and P by Picea abies and Betula pendula grown in unlimed and limed peat
Uptake of P(P-32) and Ca(Ca-45) by seedlings of Picea abies (L.) Karst and Betula pendula Roth, non-mycorrhizal or mycorrhizal with Paxillus involutus (Batsch: Fr) Fr. was studied. Seedlings were grown in unamended peat (pH 4.0) or in peat limed (CaO) to pH 5.1 or 6.1. A double-labelled (P-32 and Ca-45) complete nutrient solution was added to the peat 7 wk after planting. An 8 d period was allowed
Organizational Effectiveness of Ugandan Building Firms as Viewed by Craftsmen
Construction industries, especially those in developing countries, face the problems of low productivity. It comes about partly due to organizational ineffectiveness. The major attributes of organizational effectiveness are identified from literature. Means to achieving greater organization effectiveness and higher productivity are identified under the major headings of cohesion and morale of work
Hypertension mechanisms causing stroke
1. Although it is well established that hypertension is the main risk factor for stroke, the complexity of cerebrovascular problems related to hypertension is not generally appreciated. 2. Hypertension can cause stroke through many mechanisms. A high intraluminal pressure will lead to extensive alteration in endothelium and smooth muscle function in intracerebral arteries. The increased stress on
Health effects of occupational exposure to acrylamide using hemoglobin adducts as biomarkers of internal dose
OBJECTIVES: This study assessed the health effects of occupational acrylamide exposure using hemoglobin (Hb) adducts as biomarkers of internal dose. METHODS: Two hundred and ten tunnel workers exposed for about 2 months to a chemical-grouting agent containing acrylamide and N-methylolacrylamide underwent a health examination. Blood samples were drawn for the analysis of Hb adducts of acrylamide. F
Atomic Cholesky decompositions: A route to unbiased auxiliary basis sets for density fitting approximation with tunable accuracy and efficiency
Cholesky decomposition of the atomic two-electron integral matrix has recently been proposed as a procedure for automated generation of auxiliary basis sets for the density fitting approximation [F. Aquilante , J. Chem. Phys. 127, 114107 (2007)]. In order to increase computational performance while maintaining accuracy, we propose here to reduce the number of primitive Gaussian functions of the co
A distributed scheme for optimization of interdomain routing between collaborating domains
As today’s market forces the implementation of quality-of-service-enabled services spanned over multiple administrative domains, isolated and locally optimized interdomain routing decisions become increasingly inadequate. Instead, coordinated routing models are required together with joint optimization goals. Available papers and standardization documents focus on the description of technical mean
An empirical parameterization of heterogeneous ice nucleation for multiple chemical species of aerosol
A novel, flexible framework is proposed for parameterizing the heterogeneous nucleation of ice within clouds. It has empirically derived dependencies on the chemistry and surface area of multiple species of ice nucleus (IN) aerosols. Effects from variability in mean size, spectral width, and mass loading of aerosols are represented via their influences on surface area. The parameterization is inte
Interaction between poly(ethylene glycol) and C12E8 investigated by dynamic light scattering, time-resolved fluorescence quenching, and calorimetry
Dynamic light scattering (DLS), time-resolved fluorescence quenching (TRFQ), and isothermal titration microcalorimetry have been used to show that, in dilute solution, low molecular weight poly(ethylene glycol) (PEG, M-w = 12 kDa) interacts with the nonionic surfactant octaethylene glycol n-dodecyl monoether, C12E8, to form a complex. Whereas the relaxation time distributions for the binary C12E8/
Dose resolution in radiotherapy polymer gel dosimetry: effect of echo spacing in MRI pulse sequence
In polymer gel dosimetry using magnetic resonance imaging, the uncertainty in absorbed dose is dependent on the experimental determination of T2. The concept of dose resolution (Dpdelta) of polymer gel dosimeters is developed and applied to the uncertainty in dose related to the uncertainty in T2 from a range of T4 encountered in polymer gel dosimetry. Dpdelta is defined as the minimal separation
Mental representations of important real-life decisions
Two studies investigated how decision makers characterize alternatives in important real-life decisions, which they themselves had made (to leave a partner, to choose an education and to choose a home). First, the participants indicated a very high degree of involvement in the decisions studied and about half of the participants gave maximum involvement ratings for the partner decision. Second, th
Altered expression of the retinoblastoma tumor-suppressor gene in leukemic cell lines inhibits induction of differentiation but not G1-accumulation
The retinoblastoma tumor-suppressor gene, RB, has been implicated in tumor suppression, in regulation of the cell cycle, and in mediating cell differentiation. RB is necessary for hematopoiesis in mice, and aberrant RB-expression is associated with the progress and prognosis of leukemia. We have used antisense oligonucleotides, established clones stably expressing an antisense RB construct, and al
