摘要:
A refractory structural element is provided that is useful for lining the inner surface of a construct typically used as a kiln or other high temperature system. An element includes a stem portion associated with a flared end block portion whereby the flared end block portion is compatible with other structural elements to form a substantially continuous tiled surface when a plurality of refractory structural elements are laid adjacent to each other. The stem portion optionally has a plurality of protrusions decorated on its outer surface that may serve to adjust heat dissipation from the element.

A cementitious material is provided that includes a phosphate based component and an alkali earth component. The alkali earth ion component has as a majority source a calcium aluminate calcium ion source of dodeca-calcium hepta-aluminate, or tricalcium aluminate. Magnesium oxide that has been fused and crushed to a size of less than 200 microns, alone or in combination with the calcium aluminate calcium ion source is also provided as the alkali earth ion component. When the phosphate based component and alkali earth ion components are combined in appropriate proportions, a rigid structure is obtained. A cementitious material formulation is also provided having an aqueous acidic phosphate solution as a part B and an alkali earth ion source as a part A that includes calcium aluminate, magnesium oxide or a combination thereof. Other additives include strength enhancing insoluble phosphate additive, an impurity metal reaction suppressant, tackifiers, anti-foaming agents, and the like.

摘要:
A method for determining the masses of ions of a sample that contains a known class of biopolymers and is measured with a mass spectrometer having a statistical or pseudo-statistical error distribution includes acquiring a mass spectrum of ions of biopolymers of the known class in the sample in which mass spectrum the mass values of ions of biopolymers from the known class are concentrated in known distributions around a set of most probable mass values. At least one measured mass value of the mass spectrum is replaced by that one of a set of most probable mass values that is nearest to the measured mass value, or by a weighted average of the measured mass value averaged with that one of the set of most probable mass values that is nearest to the measured mass value.

A refractory composition and processes for manufacture are provided where the compositions possess improved refractory alkali resistance and superior handling properties. Compositions and processes for their manufacture may include a plurality of ceramic particles and a binder sintered to the particles wherein the binder includes crystalline aluminum orthophosphate distributed as the result of an in situ reaction of aluminum metaphosphate with alumina. Kits provided according to the invention provide materials for use in manufacture of a composition where the kit includes aluminum metaphosphate and a nonfacile additive.
摘要:
Aspects relate to methods for processing individual spectra acquired with a time-of-flight mass spectrometer to form a sum spectrum. The peak position of a peak and its total intensity are determined in an individual spectrum, and entries in an addition raster of the sum spectrum adjacent to the peak position are selected; then the total intensity is divided up into portions, wherein more of the total intensity is added to entries which are closer to the peak position than is added to entries which are further away from the peak position.

摘要:
Methods and instruments are provided for processing individual spectra of a time-of-flight mass spectrometer to form a sum spectrum. According to an aspect of the invention, a peak position on a flight time scale and a total intensity are determined for each peak in the individual spectrum. Intensity entries of the sum spectrum are selected, the flight times of which are positioned on both sides of the peak position. The total intensity is added to the selected intensity entries, where more of the total intensity is added to the intensity entries that are closer to the peak position than is added to the intensity entries that are further away from the peak position.
