Calculations of large-scale displacement distances were made to evaluate the combined effect of small-scale movement pattern of a Collembola, Protaphorura armata. The effect of presence of food and conspecific density on turning angle, step length and activity/motility was investigated. Calculations of net square displacement were made both by assuming correlated random walk (CRW) and by resamplin
Westphal's thesis contains a summary of earlier structural analyses of Hebrews. Her own discourse analysis structures Hebrews into three parts 1) 1:1–4:16; 2) 4:11–7:28 and 8:1–10:25; 3) 10:19–13:25. Westphal characterizes Heb 4:11-16 and 10:19-25 as "overlapping" parts and as keys to the structure and meaning of Hebrews. The structure according to this approach is not new. A shortcoming in this t
Actions and events are central to a semantics of natural language. In this article, we present a cognitively based model of these notions. After giving a general presentation of the theory of conceptual spaces, we explain how the analysis of perceptual concepts can be extended to actions and events. First, we argue that action space can be analyzed in the same way as, for example, colour space or
The generation of diversity for directed protein evolution experiments shows an important bottleneck in the in vitro random mutagenesis protocols. Most Of them are biased towards specific changes that eventually confer a predicted and conservative mutational spectrum, limiting the exploration of the vast protein space. The current work describes a simple methodology to in vivo recombine mutant lib
Aim: This thesis serves two purposes. First, it informs specialists in global public health to consider a broader spectrum of pediatric disease. Second, it informs specialists in pediatric hospital care of how the feasibility of their clinical practice depends on a functioning health care system. Methods: The papers contextualize pediatric disease entities that so far have received relatively sp
The formation of amyloid fibrils by the intrinsically disordered protein alpha-synuclein is a hallmark of Parkinson disease. To characterize the microscopic steps in the mechanism of aggregation of this protein we have used in vitro aggregation assays in the presence of preformed seed fibrils to determine the molecular rate constant of fibril elongation under a range of different conditions. We sh
PURPOSE: To examine the expression of interstitial extracellular matrix components and their role during retinal development. MATERIAL AND METHODS: Fibronectin (FN), collagen IV (Coll IV) and laminin 5 (Lam 5) expression in rat retinas from developmental stages E17 to adult were studied. In addition, PN5 full-thickness retinas were cultured for 7 days with dispase, which selectively cleaves FN and
Epidemic keratoconjunctivitis (EKC) is a severe disease of the eye, caused by members of the Adenoviridae (Ad) family, with symptoms such as keratitis, conjunctivitis, pain, edema, and reduced vision that may last for months or years. There are no vaccines or antiviral drugs available to prevent or treat EKC. It was found previously that EKC-causing Ads use sialic acid as a cellular receptor and d
Aim A defunctioning loop ileostomy in low anterior resection reduces the incidence and morbidity of an anastomotic leakage, but complications related to the stoma may occur. We explored stoma-associated complications during the stoma period and after stoma reversal. Methods A retrospective analysis of rectal cancer patients operated with low anterior resection and a defunctioning loop ileostomy at
The European Spallation Source (ESS) is an intergovernmental project building a multidisciplinary research laboratory based upon the world's most powerful neutron source to be built in Lund, Sweden. The ESS will use a superconducting linear accelerator which will deliver protons with 5 MW of power to the target at 2.0 GeV with a nominal current of 62.5 mA. A cryomodule test stand will be supplied
We have investigated the accumulation capacitance-voltage characteristics for capacitors with narrow band gap materials using modeling and experiments. The capacitance for InAs and In0.53Ga0.47As capacitors with a HfO2 oxide layer has been calculated using atomistic tight-binding, effective mass, and semiclassical nonparabolic models. The simulations show that band structure effects have a strong
Detailed (222)radon (Rn-222) flux maps are an essential pre-requisite for the use of radon in atmospheric transport studies. Here we present a high-resolution Rn-222 flux map for Europe, based on a parameterization of Rn-222 production and transport in the soil. The Rn-222 exhalation rate is parameterized based on soil properties, uranium content, and modelled soil moisture from two different land
Our tactile perception of external objects depends on skin-object interactions. The mechanics of contact dictates the existence of fundamental spatiotemporal input features-contact initiation and cessation, slip, and rolling contact-that originate from the fact that solid objects do not interpenetrate. However, it is unknown whether these features are represented within the brain. We used a novel
Hypersonic vehicles have to withstand extremely high aerodynamic heating and pressure loads during the ascent and reentry stages. Multilayer thermal insulations have been widely designed in thermal protection systems to keep the temperature of underlying structure within an acceptable limit. In this study, a theoretical model is built combining radiation and conduction heat transfer in high temper
