Understanding of Forster resonance energy transfer (FRET) in thin films composed of quantum dots (QDs) is of fundamental and technological significance in optimal design of QD based optoelectronic devices. The separation between QDs in the densely packed films is usually smaller than the size of QDs, so that the simple point dipole approximation, widely used in the conventional approach, can no lo

The aim of this sociology of law-orientated article is to analyse and describe legislative and regulatory processes concerning the task given to schools focusing on environment and sustainable development. We are describing the policy-making processes in this field from 1990 to 2011. The study involves key interviews and content analysis of national policy documents as well as legal sources, in or

This chapter does not deal with any practical aspects of light measurement, only with theoretical concepts. The following concepts are explained: energy fluence, energy fluence rate, photon fluence, photon fluence rate, radiance and mol, as well as the following superfluous or obsolete terms and synonyms: actinic flux, space irradiance, scalar irradiance, spherical irradiance, vectorial irradiance

We are good at discussing law statements of different epistemic status, and to describe logical relationships between different law statements. But contemporary discussion often suffers from a difficulty to formulate questions concerning laws of different ontological status. This paper presents a framework for distinguishing between properties and fake properties that seems to provide better tools

This paper describes trade-offs involved in designing a dual-band CMOS frontend for wireless local-area network (WLAN). Three 0.18μm CMOS frontends have been investigated, a single-band frontend at the 2.4 GHz ISM band, a single-band frontend at the 5 GHz U-NII band and a dual-band frontend. The study shows that employing a dual-band frontend yields satisfactory results, although some compromises

Proteins from halophilic microorganisms thriving at high salinity have an excess of charged carboxylate groups, and it is widely believed that this gives rise to an exceptionally strong hydration that stabilizes these proteins against unfolding and aggregation. Here, we examine this hypothesis by characterizing the hydration dynamics of a halophilic model protein with frequency- and temperature-de

A series of bistridentate ruthenium(II) polypyridyl-type complexes based on the novel 2,6-di(quinolin-8-yl)pyridine (dqp) ligand have been synthesized and their photophysical properties have been studied. The complexes are amenable to substitution in the 4-position of the central pyridine with conserved quasi-C-2v symmetry, which allows for extension to isomer-free, rod-like molecular arrays for v

Objective: To study the association between maternal drug use in early pregnancy and orofacial cleft in the infant. Design: Register analysis based on prospectively collected information. Patients: All delivered women in Sweden July 1, 1995, through December 31, 2001. Main outcome measure: Presence of orofacial cleft in infant. Results: Prospective information on maternal drug use during the first
