Vart tog behaviorismen vägen? : Social responsivitet mellan barn och vuxen, hund och människa.

This thesis studies how humans and other social responsive animals can meet and get together as companion species and what role radical behaviorist B F Skinner’s learning theory and operant conditioning possibly can play in this. Drawing from theories of discourse and discourse analysis, social responsivity and companion species, the thesis analyzes what happens with Skinner’s learning theory when

Nonlinear Beam Physics

A condensed treatment of conventional beam physics (both linear and nonlinear) is given for the non-expert; this constitutes a minimum knowhow for constructing simulations of rudimentary beamlines. The criteria for an ideal nonlinear charged-particle simulation algorithm are then presented, leading to the derivation of a symplectic, explicit, Lorentz-covariant integrator.Space charge (inter-particA condensed treatment of conventional beam physics (both linear and nonlinear) is given for the non-expert; this constitutes a minimum knowhow for constructing simulations of rudimentary beamlines.

Epicardial Right Free Wall Mapping in Chronic Atrial Fibrillation—Documentation of Repetitive Activation with a Focal Spread—A Hitherto Unrecognized Phenomenon in Man

BACKGROUND: Previous studies have shown that atrial fibrillation of recent onset in man is based on a varying number of simultaneously present activation waves reentering either themselves or each other. In the present study, right atrial activation during chronic atrial fibrillation in man was studied. METHODS AND RESULTS: In 16 patients with chronic atrial fibrillation multiple epicardial record

Effects of Art and Design on Orientation in Healthcare Architecture : A study of wayfinding and wayshowing in a Swedish hospital setting

This thesis investigates the role of interior design elements, especially artwork, in way-searchers’ wayfinding and orientation in hospital environments. The thesis considers the way-searcher’s background and the impact of cultural belonging, occupation, memories, aesthetic preferences, and language, and the influence that such factors might have on the perception of the hospital environment and i

Characterization of the Mt4 gene from Medicago truncatula

Previously we identified Mt4, a phosphate starvation inducible cDNA from Medicago truncatula which is down-regulated in roots in response to phosphate fertilization as well as colonization by arbuscular mycorrhizal (AM) fungi. Here we present further studies of Mt4. Expression was highly sensitive to exogenous applications of phosphate fertilizer; transcripts were abundant in roots fertilized with

Camera Pose Estimation with Unknown Principal Point

To estimate the 6-DoF extrinsic pose of a pinhole camera with partially unknown intrinsic parameters is a critical sub-problem in structure-from-motion and camera localization. In most of existing camera pose estimation solvers, the principal point is assumed to be in the image center. Unfortunately, this assumption is not always true, especially for asymmetrically cropped images. In this paper, w

Biosensing using arrays of vertical semiconductor nanowires : mechanosensing and biomarker detection

Due to their high aspect ratio and increased surface-to-foot-print area, arrays of vertical semiconductor nanowires are used in numerous biological applications, such as cell transfection and biosensing. Here we focus on two specific valuable biosensing approaches that, so far, have received relatively limited attention in terms of their potential capabilities: cellular mechanosensing and lightgui

Nonlinear Dynamic Output Feedback Stabilization of Moore-Greitzer Models with Quadratic Constraints

Here, we propose a new procedure for output feedback design for systems with nonlinearities satisfying quadratic constraints. It provides an alternative for the classical observer-based design and relies on transformation of the closed-loop system with a dynamic controller of particular structure into a special block form. Asymptotic stability is shown using Lyapunov theory with strictly positive

rhIGF-1/rhIGFBP-3 in Preterm Infants : A Phase 2 Randomized Controlled Trial

Objective: To investigate recombinant human insulin-like growth factor 1 complexed with its binding protein (rhIGF-1/rhIGFBP-3) for the prevention of retinopathy of prematurity (ROP) and other complications of prematurity among extremely preterm infants. Study design: This phase 2 trial was conducted from September 2014 to March 2016. Infants born at a gestational age of 230/7 weeks to 276/7 weeks

The production of geminates in Italian-dominant bilinguals and heritage speakers of Italian

This study examines cross-linguistic influence (CLI) in adult Italian-German bilinguals based on the production of gemination, a phenomenon that exists in Italian but not in German. We analyzed the spontaneous Italian speech of two groups of Italian-German bilinguals (heritage speakers of Italian and Italian-dominant bilinguals) and a monolingual Italian control group. The results show that the ge

Hydrogeophysical and hydrochemical characteristics of Pliocene groundwater aquifer at the area northwest El Sadat city, West Nile Delta, Egypt

Due to the overpopulation in the main cities and shortage of water in Egypt, finding new possible reclamation areas becomes an urgent necessity. The area northwest of El Sadat city can be considered one of the most promising new reclamation areas. This study focuses on detecting the groundwater aquifers, delineating the best localities to drill groundwater boreholes, and evaluation of the groundwa
