Using oxygen-quenched pressure-sensitive paint for oxygen concentration measurements in low-temperature combustion environments

The feasibility of using pressure-sensitive paint for oxygen concentration measurements in low-temperature combustion environments has been investigated and applied to slow combustion processes. In addition, the temperature limitation for this application was studied. A Nd:YAG laser system, a PMT and fiber-optics were used for developing a compact probe for oxygen measurements. The lifetime sensit

Event-by-event mean p(T) fluctuations in pp and Pb-Pb collisions at the LHC

Event-by-event fluctuations of the mean transverse momentum of charged particles produced in pp collisions at root s = 0.9, 2.76 and 7 TeV, and Pb-Pb collisions at root S-NN = 2.76 TeV are studied as a function of the charged-particle multiplicity using the ALICE detector at the LHC. Dynamical fluctuations indicative of correlated particle emission are observed in all systems. The results in pp co

Ternary Hom-Nambu-Lie algebras induced by Hom-Lie algebras

The need to consider n-ary algebraic structures, generalizing Lie and Poisson algebras, has become increasingly important in physics, and it should therefore be of interest to study the mathematical concepts related to n-ary algebras. The purpose of this paper is to investigate ternary multiplications (as deformations of n-Lie structures) constructed from the binary multiplication of a Hom-Lie alg

Controlled exposure to particulate matter from urban street air is associated with decreased vasodilation and heart rate variability in overweight and older adults

Background: Exposure to particulate matter (PM) is generally associated with elevated risk of cardiovascular morbidity and mortality. Elderly and obese subjects may be particularly susceptible, although short-term effects are poorly described. Methods: Sixty healthy subjects 25 males, 35 females, age 55 to 83 years, body mass index > 25 kg/m(2)) were included in a cross-over study with 5 hours of

Fruit and vegetable intake and type 2 diabetes: EPIC-InterAct prospective study and meta-analysis

Fruit and vegetable intake (FVI) may reduce the risk of type 2 diabetes (T2D), but the epidemiological evidence is inconclusive. The aim of this study is to examine the prospective association of FVI with T2D and conduct an updated meta-analysis. In the European Prospective Investigation into Cancer-InterAct (EPIC-InterAct) prospective case-cohort study nested within eight European countries, a re

Fe-amino acid complexes immobilized on silica gel as active and highly selective catalysts in cyclohexene epoxidation

In this work, the syntheses, structure, superoxide dismutase (SOD) activity, and the catalytic use in the oxidative transformations of cyclohexene of covalently grafted Fe(III)-complexes formed with various or various combinations of C-protected amino acid (l-histidine, l-tyrosine, l-cysteine and l-cystine) ligands are presented. The structural features of the surface complexes were studied by XAN

Study of the on-route operation of a waste heat recovery system in a passenger vessel

Waste heat recovery systems for power generation are gaining interest among the marine transport sector as a solution to accomplish the upcoming more restrictive regulations on emissions, and to reduce the total fuel consumption. In this paper we evaluate how a waste heat recovery system based on a regenerative organic Rankine cycle (rORC) could improve the performance of a passenger vessel. The c

Hobbes om frihet, lag och artificiella handlingar

I artikeln analyseras Thomas Hobbes frihetsbegrepp i relation till lag, rätt och det politiska tillståndets artificiella karaktär i avsikt att förstå hur Hobbes kan förena politisk absolutism med medborgarnas villkorade rätt att vara olydiga.

Spectral phase measurement of a Fano resonance using tunable attosecond pulses.

Electron dynamics induced by resonant absorption of light is of fundamental importance in nature and has been the subject of countless studies in many scientific areas. Above the ionization threshold of atomic or molecular systems, the presence of discrete states leads to autoionization, which is an interference between two quantum paths: direct ionization and excitation of the discrete state coup

Event-Based Control and Estimation with Stochastic Disturbances

This thesis deals with event-based control and estimation strategies, motivated by certain bottlenecks in the control loop. Two kinds of implementation constraints are considered: closing one or several control loops over a data network, and sensors that report measurements only as intervals (e.g. with quantization). The proposed strategies depend critically on _events_, when a data packet is sent

Risk and prediction of violent crime in forensic psychiatry

Popular Abstract in Swedish Syfte: Att undersöka den prediktiva precisionen hos ålder för missbruksdebut, MAO-B aktiviteten i blod, samt olika kombinationer av kriminologiska och kliniska riskfaktorer med avseende på återfall i våldsbrott hos tidigare våldsbrottsdömda i en prospektiv svensk uppföljningsstudie. Studiepopulation: Hundra våldsbrottslingar, konsekutivt intagna för rättspsykiatrisk undObjective: To test the predictive accuracy for violent recidivism of the age at onset of substance abuse, the platelet MAO-B activity, and various combinations of criminological and clinical risk factors among violent offenders in a prospective Swedish follow-up study. Subjects: One hundred violent offenders, consecutively admitted for forensic psychiatric investigations between 1998 and 2001 (bas

Electrochemical and XAS investigation of oxygen reduction reaction on Pt-TiO2-C catalysts

Pt-TiO2-C composites with different titanium oxide loading were synthesized by photo-deposition and chemical vapor deposition methods. The changes in their electronic properties improve the electrochemical activity toward the oxygen reduction reaction (ORR) compared to the Pt-C catalyst synthesized at the same conditions. The platinum samples were physically characterized by means of Transmission

The impact of androgen receptor polymorphism and parental ethnicity on semen quality in young men from Latvia

Recent studies on young men from the general population have demonstrated geographic and ethnic differences in semen quality. The aim of this study was to investigate whether reported ethnic differences in semen quality might be associated with the maternally derived CAG and GGN polymorphisms in the androgen receptor gene or paternal ethnicity. In total 114 military conscripts from Latvia were inc

Staff's Collaborative work process with an adolescent boy with autism and intellectual disability in a community-based sheltered housing

The aim of this single-case study was to describe the staff's collaborative work process for a period of 3.5 years caring for an adolescent boy with autism and intellectual disabilities living in an apartment of his own together with his caregivers. The longitudinal data included the staff's (two men and two women) common open diary, repeated individual interviews and focus group interviews. Detai

The solids-flux theory - Confirmation and extension by using partial differential equations.

The solids-flux theory has been used for half a century as a tool for estimating concentration and fluxes in the design and operation of secondary settling tanks during stationary conditions. The flux theory means that the conservation of mass is used in one dimension together with the batch-settling flux function according to the Kynch assumption. The flux theory results correspond to stationary
