Simulations with the Explicit Microphysics Model (EMM) of a case of lightly precipitating, glaciated stratiform cloud are presented. This frontal cloud was observed by the UK Met Office C-130 aircraft and the dual-polarization radar at Chilbolton in southern England. The Hallett-Mossop (H-M) process was found to cause extremely high number concentrations of crystal columns of up to almost 1000 1(-
Box jellyfish, or cubomedusae (class Cubozoa), are unique among the Cnidaria in possessing lens eyes similar in morphology to those of vertebrates and cephalopods. Although these eyes were described over 100 years ago, there has been no work done on their electrophysiological responses to light. We used an electroretinogram ( ERG) technique to measure spectral sensitivity of the lens eyes of the C
The Strategic Systemic Thinking (SST) framework is presented as a stepping stone towards enabling the refocusing of organizational analysis in Information Systems (IS). The paper introduces some of the fundamental assumptions regarding the objectives of the SST framework; such as sense making as learning processes build upon communicative actions. The main concepts of the SST framework are present
In neural transplantation studies, there is an interest in identifying and isolating mesencephalic dopamine (mesDA) neuron precursors that have the capacity to differentiate into fully mature mesDA neurons after transplantation. We report here that in the developing ventral mesencephalon (VM) the proneural gene Neurogenin2 (Ngn2) is expressed exclusively in the part of the ventricular zone that gi
Despite significant advances in the understanding and modelling of turbulent combustion, no general model has been proposed for simulating flames in industrial combustion devices. Recently, the increase in computational possibilities has raised the hope of directly solving the large turbulent scales using large eddy simulation (LES) and capturing the important time-dependant phenomena. However, th
The synthesis of a C-2-symmetric cleft molecule 2 based on the fused framework between bicyclo-[3.3. 1] nonane and 4-oxo-5-azaindole, incorporating a self-complementary hydrogen-bonding motif, in both racemic and enantiomerically pure forms is reported. This cleft molecule is reminiscent of analogues of Troger's base though with different cleft dimensions and tilt angles. The framework of 2 provid
Techniques for manipulating, separating, and trapping particles and cells are highly desired in today's bioanalytical and biomedical field. The microfluidic chip-based acoustic noncontact trapping method earlier developed within the group now provides a flexible platform for performing cell- and particle-based assays in continuous flow microsystems. An acoustic standing wave is generated in etched
Background : Our aims were to evaluate the response to salvage treatment in relation to initial treatment and to evaluate prognostic factors at the time of relapse in an unselected population of relapsing patients with Hodgkin's lymphoma (HL). Patients and methods: In total, 124 patients younger than 60 yr of age with initial diagnosis of HL in Sweden relapsed between 1985 and 1995. Results : Fift
Small oligomers formed early in the process of amyloid fibril formation may be the major toxic species in Alzheimer's disease. We investigate the early stages of amyloid aggregation for the tau fragment AcPHF6 (Ac-VQIVYK-NH2) using an implicit solvent all-atom model and extensive Monte Carlo simulations of 12, 24, and 36 chains. A variety of small metastable aggregates form and dissolve until an a
ProteomeBinders is a new European consortium aiming to establish a comprehensive resource of well-characterized affinity reagents, including but not limited to antibodies, for analysis of the human proteome. Given the huge diversity of the proteome, the scale of the project is potentially immense but nevertheless feasible in the context of a pan-European or even worldwide coordination.
The capture of human acute mycloid leukemia KG-1 cells expressing the CD34 surface antigen and the fractionation of human blood lymphocytes were evaluated on polyvinyl alcohol (PVA)-cryogel beads and dimethyl acrylamide (DMAAm) monolithic cryogel with immobilized protein A. The affinity ligand (protein A) was chemically coupled to the reactive PVA-cryogel beads and epoxy-derivatized monolithic cry
Background and study aim: Small-bowel tumors account for 1%-3% of all gastrointestinal neoplasms. Recent studies with video capsule endoscopy (VCE) suggest that the frequency of these tumors may be substantially higher than previously reported. The aim of the study was to evaluate the frequency, clinical presentation, diagnostic/therapeutic work-up, and endoscopic appearance of small-bowel tumors
The objective of the study was to investigate whether spontaneous and iatrogenic preterm births are associated with different paediatric outcomes. A nationwide population-based study comprising 1 010 487 singletons used data from 1991 to 2001 from the Swedish Medical Birth Register and the Swedish Hospital Discharge Register. Intrauterine fetal deaths, unknown type of delivery onset and congenital
