Solar Energy Conversion - Natural to Artificial

Photosynthesis is the process by which energy of light is converted into chemical energy by plants, algae and photosynthetic bacteria. For this, highly specialized pigment-proteins have evolved that capture the light and transform the short-lived excited states of pigment molecules into a stable transmembrane potential. By close scrutiny of organization and processes of the photosynthetic pigment

Anion mediated diversity in the nuclearity of nickel(II) complexes with a N2O donor Schiff base: Formation of a supra-molecular chain via Br center dot center dot center dot Br interactions

Two nickel(II) complexes, [Ni(L)(2)] (1) and [Ni-2(mu(1,1)-N-3)(2)(L)(2)(DMSO)(2)] (2) [where HL = 3-(methyl-amino)propyliminomethyl-4-bromophenol, a tridentate Schiff base], have been synthesized and characterized by elemental analysis, IR, UV-Vis and fluorescence spectroscopy and single-crystal X-ray diffraction studies. The deprotonated tridentate Schiff base occupies three coordination sites o

Global sensitivity analysis of the BSM2 dynamic influent disturbance scenario generator.

This paper presents the results of a global sensitivity analysis (GSA) of a phenomenological model that generates dynamic wastewater treatment plant (WWTP) influent disturbance scenarios. This influent model is part of the Benchmark Simulation Model (BSM) family and creates realistic dry/wet weather files describing diurnal, weekend and seasonal variations through the combination of different gene

K*(892)(0) and phi(1020) production in Pb-Pb collisions at root s(NN)=2.76 TeV

The yields of the K*(892)(0) and phi(1020) resonances are measured in Pb-Pb collisions at root s(NN) = 2.76 TeV through their hadronic decays using the ALICE detector. The measurements are performed in multiple centrality intervals at mid-rapidity (vertical bar y vertical bar < 0.5) in the transverse-momentum ranges 0.3 < p(T) < 5 GeV/c for the K*(892)(0) and 0.5 < p(T) < 5 GeV/c for the phi(1020)

Two-dimensional electronic spectroscopy with double modulation lock-in detection: enhancement of sensitivity and noise resistance

In many potential applications of two-dimensional (2D) electronic spectroscopy the excitation energies per pulse are strictly limited, while the samples are strongly scattering. We demonstrate a technique, based on double-modulation of incident laser beams with mechanical choppers, which can be implemented in almost any non-collinear four wave mixing scheme including 2D spectroscopy setup. The tec

Education: A Forgotten Dimension of Church Identity?

In general churches talk a lot about the importance of education. At the same time their educational praxis is often fragmentized. The most crucial factor for this is a weak connection between the Church's identity and its activity. When this link is diffuse, different activities have a tendency to live their own lives. This article examines some basic official Church documents from half a dozen c

A Component-Based Approach to Ultrasonic Self Localization in Sensor Networks

This report describes the development of an ultrasound based self localization system for mobile robots. The robot navigates using a combination of internal wheel encoders and absolute distance information from a sensor network. The sensor fusion problem is formulated as a non-linear state estimation problem which is approximated using an extended Kalman filter.

An effect of side chain length on the solution structure of poly(9,9-dialkylfluorene)s in toluene

The effect of side chain length of pi-conjugated poly(9,9-dialkylfluorene)s has been studied in semi-dilute (10 mg/mL) toluene solutions using small-angle neutron scattering (SANS) and H-1 and H-2 NMR spectroscopies. Under these conditions, SANS data indicate that poly(9,9-dinonylfluorene) and poly(9,9-dioctylfluorene) are dissolved down to the molecule level and appear as elongated one-dimensiona

Multi-radionuclide digital autoradiography of the intra-aortic atherosclerotic plaques using a monoclonal antibody targeting oxidized low-density lipoprotein.

The aim of this study was to use multi-radionuclide autoradiography to compare the different distributions of three radiolabelled tracers in an atherosclerotic mouse model. This method, along with immunohistochemistry, was applied to investigate the intra-aortic distribution of 2-deoxy-2-[(18)F]fluoro-D-glucose ((18)F-FDG), (131)I/(125)I labeled anti-oxidized Low Density Lipoprotein (oxLDL), and n

Oscillator strengths for lines of astrophysical interest in Rh II

Aims. This work reports oscillator strengths for transitions of astrophysical interest in singly ionized rhodium. Methods. Seventeen radiative lifetimes in Rh+ have been measured with the time-resolved laser-induced fluorescence technique and combined with theoretical branching fractions calculated using a relativistic Hartree-Fock model including core-polarization effects to obtain oscillator str

Pedagogerna och demokratin : En rättssociologisk studie av pedagogers arbete med demokratiutveckling

Popular Abstract in Swedish Det svenska utbildningsväsendet styrs av nationella styrdokument som skollag, läroplaner och kursplaner. Det demokratiska uppdraget är en central fråga i dessa dokument. Avhandlingens syfte är att undersöka hur pedagogerna hanterar detta demokratiuppdrag och hur de påverkas av sociala krafter på olika nivåer. Demokratibegreppet är öppet för olika tolkningar. Inom utbiThe Swedish education system is governed by national steering documents, like the Education Act, curriculi and syllabuses. The democratic assignment is a central issue in these documents. The thesis aims to investigate how teachers handle this democratic assignment and how they are influenced by forces on different social levels. The concept of democracy is open to many interpretations. Democrac

Prostate cancer risk assessment model: a scoring model based on the Swedish Family-Cancer Database

Background Many prostate cancer (PC) risk assessment models have been developed, however almost none include familial history. Aim To produce a risk assessment model for PC based on familial background of related cancers. Method 976 859 independent index men aged >= 30 in year 1998 and their family members in the Swedish Family-Cancer Database (FCD2010) were randomly divided into development (60%)

Estimability of density dependence in models of time series data

Estimation of density dependence from time series data on population abundance is hampered in the presence of observation or measurement errors. Fitting state-space models has been proposed as a solution that reduces the bias in estimates of density dependence caused by ignoring observation errors. While this is often true, I show that, for specific parameter values, there are identifiability issu

Immunoassay for the discrimination of free prostate-specific antigen (fPSA) forms with internal cleavages at Lys(145) or Lys(146) from fPSA without internal cleavages at Lys(145) or Lys(146)

Total levels of circulating prostate-specific antigen (tPSA) are strongly associated with prostate cancer (PCa) risk and outcome but benign prostate disease is the most frequent cause of a moderately elevated PSA level. Free PSA (fPSA) forms are independently associated with PCa risk and contribute modest diagnostic enhancements above and beyond tPSA alone. We developed an immunoassay for fPSA sub
