statement of problem: low- fusing compound (type 1) is used for border molding and impressions. flow and reproducibility of surface detail are two important characteristics of these materials. there are no valid data available comparing domestic and imported brands. purpose: the purpose of this study was to evaluate these two properties of four different products including kerr (kerr manufactur...

During a study of the relationship between trace element deficiencies and the free amino acids in citrus, an unknown basic nitrogen compound was detected in leaf extracts. In most samples there was more of the unknown constituent than of any other basic nitrogen compound. However, it was not present in leaf samples from trees with manganese deficiency. A comparison of its paper chromatographic ...

This paper describes a simple novel compound random field model capable of realistic modelling the most advanced recent representation of visual properties of surface materials the bidirectional texture function. The presented compound random field model combines a non-parametric control random field with local multispectral models for single regions and thus allows to avoid demanding iterative...

Hybrid organic-inorganic coordination assemblies are synthesized using modified aminocarboxylic acid ligands as the structure-directing agents. The synthetic approach results in two novel dinuclear copper(II) complexes, K2[CuII(hnida)]2.2H2O (1) and K4[CuII(chnida)]2.4H2O.4MeOH (2) that assemble in the presence of suitable counterions into a densely packed hexagonal array or an open-framework s...

We present a detailed theoretical study of three alkaline earth compounds Ca2Pb, Sr2Pb and Ba2Pb, which have undergone little previous study, calculating electronic band structures and Boltzmann transport and bulk moduli using density functional theory. We also study the corresponding tin compounds Ca2Sn, Sr2Sn and Ba2Sn. We find that these are all narrow band gap semiconductors with an electro...

We present measurements of the low-temperature thermal conductivity of a number of polymeric and composite materials from 0.3 to 4 K. The materials measured are Vespel SP-1, Vespel SP-22, unfilled PEEK, 30% carbon fiber-filled PEEK, 30% glass-filled PEEK, carbon fiber Graphlite composite rod, Torlon 4301, G-10/FR-4 fiberglass, pultruded fiberglass composite, Macor ceramic, and graphite rod. The...

Affinity materials based on halogen bonds turned out to be a powerful tool for the molecular recognition of acetone or related carbonyl compounds in the presence of ubiquitous protic molecules. The superior selectivity and sensitivity were found by the gravimetric detection of volatile organic compounds by quartz crystal microbalances.

In this paper, we examined the availability of raw woods as glycolic materials. It was found that some wood materials such as bamboo, larch and cherry could degrade glucose. Glucose is degraded to carbon dioxide via an unknown acidic compound. We then examined whether these wood materials could degrade various sugars. Larch, bamboo and cherry show high degradation rates for glucose, galactose, ...
