In this study, an oxygen monitoring system was demonstrated for sensitive oxygen detection. The system is based on tunable diode laser absorption spectroscopy (TDLAS) and wavelength modulation spectroscopy (WMS). Stable 2nd-harmonic signals of oxygen were detected by measuring the oxygen P9 absorption line at 764.38. nm. In the detection, a cubic diffuse integrating cavity was employed as a gas ab
Steep declines in photovoltaic (PV) technology prices have directed attention to the so-called soft costs associated with PV deployment. This paper focuses on one element of soft costs: those that arise from local permitting and inspection processes typically being handled by municipalities. Based on a literature review, the paper compares the status of local PV permitting in the US and Germany. R
Reaction of Ru3(CO)12 with tris(2-thienyl)phosphine (PTh3) in CH2Cl2 at room temperature or in THF in the presence of a catalytic amount of Na[Ph2CO] furnishes the carbonyl substitution products Ru3(CO)11(PTh3) (1), Ru3(CO)10(PTh3)2 (2), and Ru3(CO)9(PTh3)3 (3). Heating 1 in toluene affords the cyclometalated cluster Ru3(CO)9{μ-Th2P(C4H2S)}(μ-H) (4) resulting from carbonyl loss and carbon-hydrogen
The use of plastic scintillation microspheres (PSm) is an innovative technique for measuring the radioactivity of beta-emitting radionuclides. PSm can be produced via different methods; none of which has been assayed at the industrial scale. In the present paper, we evaluate the production of PSm by spray-drying on an industrial scale. Our results indicate that fluorescent solutes were indeed enca
The study investigated subjective theories of dream function (why do we dream)- measured as level of agreement with selected prescientific and contemporary views of science (N = 667) and thus explored differences in dream attitude with respect to age, educational level, and sex. A factor analysis revealed 3 factors. One can be described as seeing dreams as meaningful information processing (memory
Romani chib har talats i Sverige i 500 år. Det är inte ett enhetligt, väldefinierat språk, som man kan skriva en enkel grammatik om. Tvärtom, i Sverige talas en stor mängd väldigt olika varianter av romani chib. Några har talats här länge, andra bara en kort tid.Boken fokuserar på de tre varianter som har talats längst i Sverige: skandoromani, kelderash och kale. Förutom språken behandlar boken ta
In a composite film of Cdx Sey Zn1-x S1-y gradient core-shell quantum dots (QDs) and gold nanorods (NRs), the optical properties of the QDs are drastically affected by the plasmonic nanoparticles. We provide a careful study of the two-step formation of the film and its morphology. Subsequently we focus on QD luminescence photoactivation - a process induced by photochemical changes on the QD surfac
Wildfires are not only a threat to human property and a vital element of many ecosystems, but also an important source of air pollution. In this study, we first review the available evidence for a past or possible future climate-driven increase in wildfire emissions in Europe. We then introduce an ensemble of model simulations with a coupled wildfire-dynamic-ecosystem model, which we combine with
In this paper, we have investigated, by means of quantitative and statistical methods, stability and change in cultural vocabulary of Indo-European in Europe, with a focus on agriculture. For this purpose we have created a culture vocabulary list with lexical head words, organized into subcategories based on their role and function in a cultural system, the purpose of which is to give a representa
The effects of charge overlap, or charge penetration, are neglected in most force fields and interaction terms in QM/MM methods. The effects are however significant at intermolecular distances near the van der Waals minimum. In the present study, we propose a method to evaluate the intermolecular Coloumb interaction using Slater-type functions, thus explicitly modeling the charge overlap. The comp
The influence of standard language varieties on rural dialects is an important factor involved in dialect loss, which is widespread in Europe. In this study, we look at how the three-gender system in the Jämtlandic dialect of Sweden is changing under pressure from the two-gender system of Standard Swedish. The Jämtlandic dialect is an understudied Swedish dialect and an interesting object of study
