The formation and growth of tetrapropylammonium-templated crystal nuclei silicalite from a clear homogeneous solution was recorded in situ as function time at temperatures between 90 115 °C using small-angle X-ray scattering (SAXS). kinetics the nucleation process studied give an apparent activation energy 70 kJ mol-1. A neutron (SANS) contrast variation study confirms that contain tetrapropylammonium template expected stoichiometry completed crystal. Infrared spectroscopy provides evidence...

We report the first results of nondisruptive, central fueling a tokamak by injection an accelerated spheromak compact toroid (CT). Interferometry measurements indicate plasma on fast time scale (0.5 ms), with more than 50% CT mass used for fueling. The particle inventory increased 30% without disruption.
Recombinant human beta ig-h3 was found to bind 125I-labeled small leucine-rich proteoglycans (SLRPs), biglycan, and decorin, in co-immunoprecipitation experiments. In each instance the binding could be blocked by an excess of unlabeled proteoglycan, confirming specificity interaction. Scatchard analysis showed that biglycan bound more avidly than decorin with Kd values estimated as 5.88 x 10(-8) 1.02 10(-7) M, respectively. reciprocal blocking experiments both inhibited others indicating...
Dynamic light scattering (DLS) is widely used for particle size determination in the sub-micrometer range. The utility of combining simultaneous multiangle DLS and static (SLS) obtaining more robust reproducible distributions has recently been demonstrated (Langmuir 1995, 11, 2480−2485). This approach yields excellent results but tedious demands high-quality SLS data which, turn, require a sophisticated photometer system. In this paper we investigate ways to improve further attractiveness by...
Abstract Internal Brownian motions of clean ϕ29 and λ‐DNAs have been studied using photon‐correlation techniques at both visible (λ 0 = 632.8 nm) uv 363.8 wavelengths. The present dynamic light scattering data, which extend to K 2 19 × 10 cm −2 , can in every case be satisfactorily simulated by a Rouse‐Zimm model polymer with an appropriate choice the three parameters. effects pH, salt concentration, single‐strand breaks, molecular weight on those parameters also investigated. Intact DNAs...
Imaging photoplethysmography is a relatively new technique for extracting biometric information from video images of faces. This useful in non-invasive monitoring patients including neonates or the aged, with respect to sudden infant death syndrome, sleep apnoea, pulmonary disease, physical mental stress and other cardio-vascular conditions. In this paper, we investigate limits detection heart rate (HR) while reducing quality. We compare performance three independent component analysis (ICA)...

The distribution of the blood-groups in persons suffering from mental disease has been widely investigated, but literature is full conflicting statements. It may fairly be taken that no one yet demonstrated any statistically significant alteration blood-group other disease, there have many claims for variation diseases.
We report an investigation of the effect Aerosol OT on surface charge silica particles suspended in decane. The electrophoretic mobilities were measured using phase analysis light scattering, and supporting evidence was provided by conductivity adsorption isotherm measurements. results showed that, as concentration increased, a sign reversal mobility occurred. This observation is explained qualitatively site-binding model charging mechanism.

The principle explained associated instrumentation described. A number developments in instrumentation, which will have substantial impact on future application technique, are discussed.

Abstract Dynamic light‐scattering techniques are employed to study the internal Brownian motions of a commercial calf thymus DNA, clean and contaminated ϕ29 DNAs, DNA with bound spermidine as function pH. The Rouse‐Zimm model parameters both DNAs differ substantially from those in neutral‐pH region. However, this difference is largely removed by adding 0.01 M EDTA (which has no effect on DNA) sample. These findings imply existence that preparation polycation contaminants, presumably basic...

A large number of model probability density functions (PDFs) are used to analyze atmospheric scintillation statistics. We have analyzed data from two different experimental setups covering a range strengths determine which candidate PDFs best describe the data. The were fitted using method least squares. root-mean-squared fitting error was monitor goodness fit. results found depend strongly on strength. find that log normally modulated Rician and normal fit over encountered.
In particle size measurement with dynamic light scattering (DLS), it is difficult to get an accurate recovery of a bimodal distribution (PSD) peak position ratio less than ~2:1, especially when large particles (>350nm) are present. This due the inherent noise in autocorrelation function (ACF) data and scarce utilization PSD information during inversion process. this paper, ACF investigated. It was found that initial decay section contains more information, for PSD. Based on this,...
Dynamic light scattering (DLS) is a popular method of particle size measurement, but at ultra-low concentrations, the occurrence number concentration fluctuations limits use technique. Number add non-Gaussian term to scattered intensity autocorrelation function (ACF). This leads an inaccurate distribution (PSD) being recovered if normal DLS analysis model used. We propose two methods for inverting data and recovering PSDs when are apparent. One directly establish relationship between ACF PSD...
