Alkane C-H bond activation by various catalysts and enzymes has attracted considerable attention recently, but many issues are still unanswered. The conversion of ethane to ethanol and ethene by bare [Fe-III=O](+) has been explored using density functional theory and coupled-cluster method comprehensively. Two possible reaction mechanisms are available for the entire reaction, the direct H-abstrac

Background: The aim of this study was to compare maternal labour and birth outcomes between women who gave birth on a birth seat or in any other position for vaginal birth and further, to study the relationship between synthetic oxytocin augmentation and maternal blood loss, in a stratified sample. Methods: A re-analysis of a randomized controlled trial in Sweden. An on-treatment analysis was used

Patch-clamp and capacitance measurements were applied to α-, β- and δ-cells in intact mouse pancreatic islets. The maximum rate of β-cell exocytosis during a depolarization to 0 mV was 14 granules/s, <5% of that observed in isolated β-cells. β-cell exocytosis exhibited bell-shaped voltage dependence and peaked at +20 mV. At physiological membrane potentials (≤-20 mV), the maximum rate of release w

The efficient generation of isolated attosecond pulses (IAPs), giving access to ultrafast electron dynamics in various systems, is a key challenge in attosecond science. IAPs can be produced by confining the extreme ultraviolet emission generated by an intense laser pulse to a single field half-cycle or, as shown recently, by employing angular streaking methods. Here, we experimentally demonstrate

Previous studies on autobiographical memory have focused on unimodal retrieval cues (i.e., cues pertaining to one modality). However, from an ecological perspective multimodal cues (i.e., cues pertaining to several modalities) are highly important to investigate. In the present study we investigated age distributions and experiential ratings of autobiographical memories retrieved with unimodal and

Reaction of [Ru(CO)(9){mu(3-)eta(1),kappa(1),kappa(2)-PhP(C6H4)CH2PPh}] (1) with tri(2-thienyl) phosphine (PTh3) in refluxing THF afforded [Ru-3(CO)(9)(PTh3)(mu-dpbm)] (3){dpbm = PhP(C6H4)(CH2)PPh} and [Ru-3(CO)(6)(mu-CO)(2){mu-kappa(1),eta(1)-PTh2(C4H2S)}{mu(3)-kappa(1),ka ppa(2)-Ph2PCH2PPh}] (5) in 18% and 12% yields, respectively, while a similar reaction with tri(2-furyl)phosphine (PFu(3)) gav

The performance of hybrid solar cells composed of polymer and ZnO is mainly hindered by the defects of ZnO. Here, we investigate the effects of ZnO nanoparticle surface modification with poly(ethylene oxide) (PEO) on the performance of bulk heterojunction hybrid solar cells based on poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene vinylene] (MEH-PPV) and ZnO nanoparticles. The reference device us

Advanced fire modelling software have been developed and improved during the last couple of decays and thesekinds of software have been shown to be valuable tools for fire safety engineers. However, the advances made have not replaced the need for simple hand-calculation methods. Simple hand-calculations methods can be used to obtain a first estimate of, for example, smoke layer temperatures in a per

Recent revisions to the biostratigraphic and chronostratigraphic assignment of strata from the type area of the Niagaran Provincial Series (a regional chronostratigraphic unit) have demonstrated the need to revise the chronostratigraphic correlation of the Silurian System of North America. Recently, the working group to restudy the base of the Wenlock Series has developed an extremely high-resolut

In this paper, we present a controller synthesis algorithm for a decentralized control problem. We consider an architecture in which there are two interconnected linear subsystems. Both controllers seek to optimize a global quadratic cost, despite having access to different subsets of the available measurements. Many special cases of this problem have previously been solved, most notably the state

Background-The number of circulating blood monocytes impacts atherosclerotic lesion size, and in mouse models, elevated levels of high-density lipoprotein cholesterol suppress blood monocyte counts and atherosclerosis. We hypothesized that individuals with mild renal dysfunction at increased cardiovascular risk would have reduced high-density lipoprotein levels, high blood monocyte counts, and acc

There are limited data on human papillomavirus (HPV) type-specific cervical cancer risk among human immunodeficiency virus (HIV)-positive women. Previous studies have suggested that HPV 16 would be relatively less important as a causative agent among HIV-positive compared with HIV-negative women. This study investigates HPV type-specific cervical cancer risk in a population in which HIV is endemic

Regulating transgene expression in vivo by delivering oral drugs has been a long-time goal for the gene therapy field. A novel gene regulating system based on targeted proteasomal degradation has been recently developed. The system is based on a destabilizing domain (DD) of the Escherichia coli dihydrofolate reductase (DHFR) that directs fused proteins to proteasomal destruction. Creating YFP prot

In this thesis, human behavior in rail tunnel fires is explored. Descriptive knowledge is presented related to the evacuation of passenger trains, and the subsequent tunnel evacuation to a safe location. More specifically, a theoretical framework that can aid the understanding of human behavior is identified, and its applicability to rail tunnels is demonstrated. In addition, new empirical data on

Expansion of tourism in the northern periphery regions provides innovative resources for an economic boost to many of the peripheral communities. The northern ecosystems are however extremely vulnerable. It is therefore of vital importance for such communities to plan the growth of tourism along sustainable lines in order to secure long-term economic benefit from tourism. Geographical Information

Background: In a holistic view of care, the family is important for the patient as well as for the staff and integration of family members in health care is a growing trend. Yet, family participation in the care is sparsely investigated and valid assessment instruments are needed. Setting: Data were collected from 200 family members participating in an intervention study at an emergency department
