Colloidal dispersions have attracted much attention both from academia and industry due to industrial significance and complex dynamic properties. Accordingly, a variety of attempts have been made to understand the complicated physics of colloidal dispersions. Particle dynamics simulation has been playing an important role in exploring colloidal systems as a strong complement to experimental appro

Soot emissions from diesel internal combustion engines are strictly regulated nowadays. Laser extinction measurement (LEM) and natural luminosity (NL) of sooty flames are commonly applied to study soot. LEM measures soot along the laser beam path and it can probe soot regardless of temperature. NL integrates the whole field of view and relies on soot temperature. In this work, a comparison of simu

In 2007, Chinese Ministry of Education (MOE) and Ministry of Housing & Urban-Rural Development (MOHURD) carried out the Campus Resource Conservation Actions, in order to take full use of resources and to improve the energy efficiency. However, due to the large amounts of universities, the total energy consumption and the energy efficiency situation have no objective statistics. Taking modeling

We have measured radiative lifetimes for selenium and tellurium resonance levels by using short pulse laser excitation in differentially heated resonance cells. We obtained tau(3S1 Se I) = 2.9(5) ns and tau(3S1 Te I) = 3.1(5) ns, which together with branching ratio values given by Ubelis and Berzinsh yield the absorption oscillator strength f(abs)(Se I, 196.0 nm) = 0.074(16) and f(abs)(Te I, 214.3

A modified Delphi method was used to determine thresholds for Minimum Data Set quality indicators for Icelandic nursing homes. The thresholds were then applied to quality outcomes in Icelandic nursing homes for the year 2009. The thresholds indicate areas of good or poor care and can be used for planning services. Icelandic nursing homes seem to be doing best in incontinence and nutritional care.

Consider a reflected random walk Wn+1 = (W-n +X-n)(+), where X-o, X-1,... are i.i.d. with negative mean and subexponential with common distribution F. It is shown that the probability that the maximum within a regenerative cycle with mean mu exceeds x is approximately mu (F) over bar(x) as x --> infinity, and thereby that max (W-o,..., W-n) has the same asymptotics as max(X-o,...,X-n) as n --> inf

To increase our understanding of the genetic basis of adiposity and its links to cardiometabolic disease risk, we conducted a genome-wide association meta-analysis of body fat percentage (BF%) in up to 100,716 individuals. Twelve loci reached genome-wide significance (P<5 × 10(-8)), of which eight were previously associated with increased overall adiposity (BMI, BF%) and four (in or near COBLL1/GR

This paper presents an innovative research on urban risk reduction and climate change adaptation that combines case studies, grounded theory and systems analysis, which could be used as a template for similar intersectoral and interdisciplinary investigations. Such a ‘case studies–grounded theory–systems analysis approach’ permits a grounded theory to be built from case study data, which is viewed

Given an electronic wave function, generated by the MCHF program (LS format) or the MCHF_CI program (LSJ format), this program computes the hyperfine interaction constants, A(J) and B(J). In strong experimental magnetic fields, the splitting is also affected by the off-diagonal hyperfine constants A(J,J-1), B(J,J-1), and B(J,J-2) and these are computed as well, depending on the input data.

The ambiguity domain plays a central role in estimating the time-varying spectrum of a non-stationary random process in continuous time, since multiplication in this domain is equivalent with estimating the covariance function of the random process using an intuitively appealing estimator. For processes in discrete time there exists a corresponding covariance function estimator. The ambiguity doma

Objective. Serum calcium concentrations have been associated with the risk of malignant disease, especially breast cancer. Thus, determinants of serum calcium concentrations, with special regard to risk factors of breast cancer, are of great interest. Material and methods. Previous studies have either been small or they have not focused on reproductive factors. The present study examined serum cal

Background: Despite considerable racial and geographical differences in human phenotypes and in the incidence of diseases that may be associated with sex steroid action, there are few data concerning variation in sex steroid levels among populations. We designed an international study to determine the degree to which geography and race influence sex steroid levels in older men. Methods: Using mass

In this study, we analysed the ease of use of three computer programs for self-registration of job seekers. The programs were developed in somewhat different activity contexts. The differences found between the programs in two experiments appeared to result from a combination of fewer constraints on individual input demanded by Job Seeker Bank and Af Explore and from the programs’ better adaptatio

Weak convergence of the multivariate point process of upcrossings of several high levels by a stationary Gaussian process is established. The limit is a certain multivariate Poisson process. This result is then used to determine the joint asymptotic distribution of heights and locations of the highest local maxima over an increasing interval. The results are generalized to upcrossings and local ma
