Hygroscopic properties of submicrometer atmospheric aerosol particles measured with H-TDMA instruments in various environments - a review
The hygroscopic properties play a vital role for the direct and indirect effects of aerosols on climate, as well as the health effects of particulate matter (PM) by modifying the deposition pattern of inhaled particles in the humid human respiratory tract. Hygroscopic Tandem Differential Mobility Analyzer (H-TDMA) instruments have been used in field campaigns in various environments globally over
Chemical and electromagnetic mechanisms of tip-enhanced Raman scattering
In this paper, we attempt to reveal the nature of the chemical and electromagnetic mechanisms of tip-enhanced Raman scattering (TERS). Direct visual evidence regarding the chemical mechanism via charge transfer was obtained with charge difference density. It is found that there are several kinds of charge transfer: (1) tip to molecule, (2) surface to molecule, (3) tip and surface to molecule simul
Carboxylation reactions involving carbon dioxide insertion into palladium-carbon sigma-bonds
The catalytic incorporation of CO2 into value-added chemicals to form e. g. carboxylic acids and carbonates is highly interesting due to the abundance, non-toxicity and low cost of carbon dioxide. Currently, palladium is one of the most exploited transition metals in homogeneous catalysis and its reactivity with carbon dioxide has therefore been studied to a significant extent. All work in the fie
Large-eddy simulation of turbulent flow in a stirred tank driven by a Rushton turbine
Large-eddy simulation (LES) of mixing process in a baffled tank was presented. The impeller rotation was modeled using the sliding mesh technique In this study the CFD code was used for simulation of a standard vessel agitated by a 6-blade Rushton turbine and results were evaluated in terms of the predicted flow field, power number, mean velocity components, mixing time, turbulent kinetic energy a
Observing solute transport in the capillary fringe using image analysis and electrical resistivity tomography in laboratory experiments
Five laboratory experiments were conducted to study solute transport in the capillary fringe in a sand filled glass tank containing an artificial groundwater zone, an unsaturated zone, and a capillary fringe in between. Dye stained water, applied at the soil surface, moved downwards through the unsaturated zone and then horizontally in the capillary fringe. The horizontal velocity of the dye plume
System-size dependence of open-heavy-flavor production in nucleus-nucleus collisions at root s(NN)=200 GeV
The PHENIX Collaboration at the Relativistic Heavy Ion Collider has measured open-heavy-flavor production in Cu + Cu collisions at v root s(NN) = 200 GeV through the measurement of electrons at midrapidity that originate from semileptonic decays of charm and bottom hadrons. In peripheral Cu + Cu collisions an enhanced production of electrons is observed relative to p + p collisions scaled by the n

Mononuclear complexes and a coordination polymer of the 2-pyridylamino ((NHPy)-Py-2) functionalized P(V) ligand
Three mononuclear metal complexes, [{PO2((NHPy)-Py-2)(2)}(2)M] [Py-2 - 2-pyridyl; M - Zn (1), Ni (2), Co (3)], have been synthesized by reacting metal nitrates with tetrakis(2-pyridylamino)phosphonium chloride, [P((NHPy)-Py-2)(4)]Cl, under solvothermal reaction conditions. The ligand, [P((NHPy)-Py-2)(4)]Cl, is hydrolyzed in the reaction medium. All of the complexes are isostructural and show an oc
cis-{2,6-Bis[(di-tert-butyl-phosphan-yl)meth-yl]cyclo-hexyl-κ(3) P,C (1),P'}chloridopalladium(II).
The Pd atom in the title compound, [Pd(CHP)Cl], has a distorted square-planar CClP coordination geometry with the ,,'-tridentate ligand forming two five-membered metallacycles. The cyclo-hexane ring is aligned with the Pd coordination plane due to C-H activation in an equatorial position, giving a tri-equatorial conformation of the cyclo-hexyl ring.
Clonal expansion of T/NK-cells during tyrosine kinase inhibitor dasatinib therapy
Dasatinib, a broad-spectrum tyrosine kinase inhibitor (TKI), predominantly targets BCR-ABL and SRC oncoproteins and also inhibits off-target kinases, which may result in unexpected drug responses. We identified 22 patients with marked lymphoproliferation in blood while on dasatinib therapy. Clonality and immunophenotype were analyzed and related clinical information was collected. An abrupt lympho

Defining Profiles of Functional Limitations in Groups of Older Persons: How and Why?
OBJECTIVE: Addressing the complexity of multiple health problems in the older population, the objective was to identify combinations of functional limitations for use in simulation analysis, to enable predictions of the potentially most severe person-environment fit (i.e., accessibility) problems among groups of older persons. METHOD: Utilizing data from 1,542 persons aged 75 to 89 years and apply
Amperometric In Vitro Monitoring of Penetration through Skin Membrane
The aim of this study was to demonstrate that penetration of quercetin, hydrogen peroxide and ascorbic acid through skin membranes can be monitored amperometrically. Skin membrane was fixed on the top of chemically modified electrodes and penetration of the appropriate compound was registered as electrode current. The methodology allows the study of penetration from solution as well as from pharma
Thermo-mechanically coupled model of diffusionless phase transformation in austenitic steel
Abstract in UndeterminedA constitutive model of thermo-mechanically coupled finite strain plasticity considering martensitic phase transformation is presented. The model is formulated within a thermodynamic framework, giving a physically sound format where the thermodynamic mechanical and chemical forces that drive the phase transformation are conveniently identifiable. The phase fraction is treat
Analysis of In Situ Mechanical Properties of Phases in High-Alloyed White Iron Measured by Grid Nanoindentation
The paper presents an analysis of the in situ mechanical properties (e.g., hardness, elastic modulus, and volume fraction) of phases in high-alloy white iron measured by grid nanoindentation statistically, to reveal the contributions of individual phase properties to the global properties of the material. The in situ mechanical properties of phases measured by grid indentation were validated throu
Different affinity of galectins for human serum glycoproteins: galectin-3 binds many protease inhibitors and acute phase proteins.
Here we report the first survey of galectin binding to glycoproteins of human serum. Serum was subjected to affinity chromatography using immobilized galectins, and the bound glycoproteins were analyzed by electrophoresis, Western blotting, and mass spectrometry. Galectins-3, -8 and -9 bound a much broader range of ligands in serum than previously known, galectin-1 bound less, and galectins-2, -4
