Interfacial electron transfer is one of the key processes in the novel type of photovoltaic cells-dye sensitized solar cells (DSSC). By means of transient absorption spectroscopy we have studied the dynamics of the initial photo-induced processes in dye-sensitized nano-porous thin films of wide-band gap semiconductor microcrystallines, which represent the main photoactive part of DSSC. In the most
Objective Incidence of cardiovascular disease (CVD) is higher in men than in women. The aim of this study was to investigate whether the gender differential can be modified by pharmacological intervention in a population-based setting. Design and method In a prospective population-based cohort - the Malmo Diet and Cancer study - a total of 3608 hypertensives (1559 men, 2049 women), 45-73 years old
Recent marsupials include about 280 species divided into 18 families and seven orders. Approximately 200 species live in Australia/New Guinea. The remaining species inhabit South America with some of these secondarily ranging into North America. In this study, we examine marsupial relationships and estimate their divergences times using complete mitochondrial (mt) genomes. The sampling, which incl
Results from large scale, ab initio MCHF calculations are presented for the transition properties of the 3s2 3p2(3)P(J-)e{3s3p3, 3s2 3p3d, 3s2 3p4s} 5S2o and 3P2o intercombination and resonance lines in P II. The agreement with experiment is good, the systematic approach shows convergence and the agreement between different forms of the oscillator strength is excellent for the resonance lines.
The application of a quinoprotein glucose dehydrogenase modified thick-film sensor as label detector in a capillary immunoassay (CIA) for xenoestrogens is presented. The detection of the alkylphenols and their ethoxylates is based on the competition between the analyte and tracer molecules for the binding sites of anti-alkylphenol ethoxylate antibodies. This assay is performed off-line in small di
The electrocatalytic properties for NADH oxidation of five organic dyes, two indophenol derivatives (2,6-dichlorophenolindophenol and indophenol) and three o-quinone derivatives (phenanthrenequinone, pyrroloquinoline-quinone, and 1,2-naphthoquinone) were compared when adsorbed on zirconium phosphate entrapped in carbon paste. The electrochemical behavior of the immobilized dyes was investigated wi
In this paper, two fundamentally different urban wastewater systems are assessed from an environmental impact perspective. One system represents a centralised, high-tech, end-of-pipe structure c whereas the second system is primarily based on source-separation strategies. Using material flow analysis a in combination with evaluation methods based on life-cycle assessment the systems are evaluated
We have measured the interaction cross sections (σI) of 31–40Ar and 31–37Cl on carbon targets at energies of around 950 A MeV. The effective matter radii for these nuclei were deduced by a Glauber-model analysis. Combining our matter radii with measured charge radii for Ar isotopes, we could deduce the proton-skin thicknesses for the 32–40Ar isotopes, which were found to increase monotonically wit
Lifetime measurements have been made for the radiation emitted in the ground term transitions of the nominal form 5s(2)5p(6)5d(x)6s-5s(2)5p(6)5d(x)6p in Ta II (x = 3), W II (x = 4), and Re II (x = 5). Supporting theoretical calculations have also been performed to characterize configuration interaction and to estimate the degree of decay branching of the upper levels. The lifetime measurements hav
An alpha/beta barrel is predicted for the three-dimensional (3D) structure of Bacillus subtilis ferrochelatase. To arrive at this structure, the THREADER program was used to find possible homologous 3D structures and to predict the secondary structure for the ferrochelatase sequence. The secondary structure was fit by hand to the selected homologous 3D structure then the MODELLER program was used
A flow-through microdispenser has been coupled to a micro HPLC separation system and used as a solvent elimination interface for Fourier transform infrared (FTIR) and Raman spectroscopic detection of the separated compounds. Using the microdispenser picoliter sized droplets can be generated and deposited on an appropriate target placed on a computerized x, y-stage. Evaporation of volatile solvent
This paper presents a model for reversed-phase purification of insulin from desamido insulin. The system is described by a reaction dispersive model with a competitive Langmuir isotherm. A model building and calibration method is presented and the model's region of validity is defined. The model is calibrated using only two-component experiments on the raw mixture by the inverse method and then ex
Forestry in Sweden suffers from browsing damage caused by large herbivores, mainly moose (Alces alces) and roe deer (Capreolus capreolus). Silviculture affects the availability of forage for these animals, and thus the browsing pressure. A step towards modeling the response of trees or to predict browsing damage is to gain more knowledge on the availability of food in forest stands. Individual gap
A seismic approach is used to estimate the thickness and elastic stiffness constants of asphalt or concrete slabs. The overall concept of the approach utilizes the robustness of the multichannel seismic method. A multichannel-equivalent data set is compiled from multiple time series recorded from multiple hammer impacts at progressively different offsets from a fixed receiver. This multichannel si
Wave cycles, i.e. pairs of local maxima and minima, play an important role in many engineering fields. Many cycle definitions are used for specific purposes, such as crest-trough cycles in wave studies in ocean engineering and rainflow cycles for fatigue life prediction in mechanical engineering. The simplest cycle, that of a pair of local maximum and the following local minimum is also of interes
The Multi-plume Aerosol dynamics and Transport (MAT) model has been developed to study the dynamics of the particle size distribution in urban environments. The MAT model uses a novel multi-plume scheme for vertical dispersion and routines of the aerodynamics models AERO3. It treats the processes: emission from a near ground source, dilution with background air, deposition, coagulation and condens
