Multi-Scale Characterization of Lyotropic Liquid Crystals Using 2H and Diffusion MRI with Spatial Resolution in Three Dimensions.

The ability of lyotropic liquid crystals to form intricate structures on a range of length scales can be utilized for the synthesis of structurally complex inorganic materials, as well as in devices for controlled drug delivery. Here we employ magnetic resonance imaging (MRI) for non-invasive characterization of nano-, micro-, and millimeter scale structures in liquid crystals. The structure is mi

Direct electron transfer of Phanerochaete chrysosporium cellobiose dehydrogenase at platinum and palladium nanoparticles decorated carbon nanotubes modified electrodes

In the present work, platinum and palladium nanoparticles (PtNPs and PdNPs) were decorated on the surface of multi-walled carbon nanotubes (MWCNTs) by a simple thermal decomposition method. The prepared nanohybrids, PtNPs-MWCNTs and PdNPs-MWCNTs, were cast on the surface of spectrographic graphite electrodes and then Phanerochaete chrysosporium cellobiose dehydrogenase (PcCDH) was adsorbed on the

Clinical commentary - COPD is not a systemic disease Results from the AIMAR Expert Opinion Consensus/Dissensus Seminar "COPD is/is not a systemic disease?", Venice, Italy, 13-14 November 2008

Although COPD is a major disease worldwide there is a perplexing current uncertainty about the nature of this disease. COPI) is characterized at onset and prevalently by the involvement of the lungs and bronchi, but as the disease evolves abnormalities develop in other organs and systems and the question arises: what is the pathogenesis of these respiratory and systemic impairments? Are the altera

New Aspects of Alveolar Adaptive Immune Responses in COPD

Chronic obstructive pulmonary disease (COPD) is characterised by a chronic inflammation in conducting airways and the alveolar parenchyma. The inflammation, which is a consequence of inhalation of noxious gases like tobacco smoke, has traditionally been thought to be driven by innate immune responses. However, more recent studies have revealed an increase in lymphocyte-rich lymphoid aggregates (LA

Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in root s=7 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb(-1) of root s = 7 TeV proton-proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions

Jaw-bearing polychaetes of the Silurian Eramosa Lagerstatte, Ontario, Canada

The Wenlock (middle Silurian) Eramosa Lagerstatte of the Bruce Peninsula, Ontario, Canada, is becoming known for its rich and diverse faunas, different preservational styles, and a combination of soft-body preservation associated with shelly body and trace fossils. Sampling for scolecodonts-the jaws of polychaete annelids-has yielded unique material. Hindenites parkheadensis new species is describ

On Automation in Anesthesia

The thesis discusses closed-loop control of the hypnotic and the analgesic components of anesthesia. The objective of the work has been to develop a system which independently controls the intravenous infusion rates of the hypnotic drug propofol and analgesic drug remifentanil. The system is designed to track a reference hypnotic depth level, while maintaining adequate analgesia. This is complicat

CaV1.2 rather than CaV1.3 is coupled to glucose-stimulated insulin secretion in INS-1 832/13 cells.

In clonal beta-cell lines and islets from different species, a variety of calcium channels are coupled to glucose-stimulated insulin secretion. The aim of this study was to identify the voltage-gated calcium channels that control insulin secretion in insulinoma (INS)-1 832/13 cells. The mRNA level of Ca(V)1.2 exceeded that of Ca(V)1.3 and Ca(V)2.3 two-fold. Insulin secretion, which rose tenfold in

“Use” discourses in system development: Can communication be improved?

This paper aims to provide a basis for renewed talk about "use" in computing. Four current "discourse arenas" are described. Different intentions manifest in each arena are linked to failures in "translation", different terminologies crossing disciplinary and national boundaries non-reflexively. Analysis of transnational use discourse dynamics shows much miscommunication. Conflicts like that betwe

Dependence of laser accelerated protons on laser energy following the interaction of defocused, intense laser pulses with ultra-thin targets

The scaling of the flux and maximum energy of laser-driven sheath-accelerated protons has been investigated as a function of laser pulse energy in the range of 15-380 mJ at intensities of 10(16)-10(18) W/cm(2). The pulse duration and target thickness were fixed at 40 fs and 25 nm, respectively, while the laser focal spot size and drive energy were varied. Our results indicate that while the maximu

Differential Capacitance of Room Temperature Ionic Liquids: The Role of Dispersion Forces

We investigate theoretical models of room temperature ionic liquids, and find that the experimentally observed camel-shape of the differential capacitance is strongly related to dispersion interactions in these systems. At low surface charge densities, the loss of dispersion interactions in the vicinity of the electrodes generates depleted densities, with a concomitant drop of the differential cap

PHYSICOCHEMICAL CHARACTERIZATION OF FRUIT AND VEGETABLE FIBER SUSPENSIONS. I: EFFECT OF HOMOGENIZATION

Different physicochemical properties and the chemical composition of soluble and insoluble fiber were studied. The influence of fiber source (apple, tomato, carrot and potato pulp), concentration and homogenization were investigated. The fiber suspensions respond in different ways to homogenization. This can, for most physicochemical properties investigated, be due to the fundamentally different m

cis-trans Isomers of PtX4L2 (X=halogen and L=neutral ligand): trans -bis(dimethyl sulfide)tetraiodidoplatinum(IV)

The octahedral title complex, [PtI4(C2H6S)2] or trans PtI4(dms)2 (dms is dimethylsulfide), crystallizes in the monoclinic space group P21/n (Z=2) with molecular symmetry Ci, which is the most frequently occurring point group for trans-PtX4L2[56%, 28 structures in the Cambridge Structural Database (CSD) [Allen, 2002, Acta Cryst B58, 380-388]] followed by C1 (22%, 11 structures). The complexes form

Lighting control systems in individual offices at high latitude: measurements of electricity savings and users preferences

Abstract in UndeterminedAn efficient lighting control systems (LCS) should take advantage of the natural light available, but this presents some technical challenges as well as user related issues. So far, the assessment of lighting energy consumption of LCS has been based on technical features rather than the occupants’ acceptance.This article presents the results of a monitoring study providing
