Notizen: Abstract We give necessary and sufficient conditions for the existence and uniqueness of compactly supported distribution solutionsf=(f 1,...,f r)T of nonhomogeneous refinement equations of the form $$f(x) = h(x) + \sum\limits_{\alpha \in A} {c_\alpha f(2x - \alpha )(x \in R^s )} $$ , where h=(h1,...,hr)Tis a compactly supported vector-valued multivariate distribution, A⊂Z+ s has compact support, and the coefficientsc α are real-valued r×r matrices. In particular, we find a finite dimensional matrix B, constructed from the coefficientsc α of the equation (I−B)q=p, where the vectorp depends on h. Our proofs proceed in the time domain and allow us to represent each solution regardless of the spectral radius of P(0):=2−s∑c α , which has been a difficulty in previous investigations of this nature.

Notizen: Abstract This paper begins with a brief statistical analysis to establish the significant contribution of cooking equipment fires to fire losses and injuries in Canadian homes. Due to lack of comprehensive fire loss data for Canadian homes, further analysis is focused on Alberta data. The most frequent ignition scenario, based on a top-down analysis of Alberta home fires, was the ignition of overheated cooking oil in pots, deep-fat fryers, or pans heated on stove tops. These fires also accounted for the majority of home fire injuries. Fire characteristics of cooking oils, which point to the importance of maintaining oil temperatures below their flash points, and thermostatically controlled deep-fat fryers as the best available solution to the problem are discussed.

Thema: Chemie und Pharmazie

Notizen: Summary Cluster Analysis has been shown to be partially suitable for the classification of glasses. The expansion of the clusters on theSeger's diagram allows an investigation of the influence of the different glass components. Variation of the SiO2 content results in a smaller change of properties than variation of the Na2O/RO relationship. Principal Component Analysis is convenient for showing correlations between the composition of the examined glasses, the glass structure parameters, and the different electrode properties. Properties of electrodes are mostly influenced by the content of Na2O and by the kind of the divalent cations. In contrast thereto structure parameters become basically determined by the content of SiO2 and RO. The field strength of the divalent cations plays the decisive roll again.

Thema: Biologie

Notizen: Abstract. Darwinian theory requires that mutations be produced in a nonanticipatory manner; it is nonetheless consistent to suggest that mutations that have repeatedly led to nonviable phenotypes would be introduced less frequently than others—if under appropriate genetic control. Immunoglobulins produced during infection acquire point mutations that are subsequently selected for improved binding to the eliciting antigen. We and others have speculated that an enhancement of mutability in the complementarity-determining regions (CDR; where mutations have a greater chance of being advantageous) and/or decrement of mutability in the framework regions (FR; where mutations are more likely to be lethal) may be accomplished by differential codon usage in concert with the known sequence specificity of the hypermutation mechanism. We have examined 115 nonproductively rearranged human Ig sequences. The mutation patterns in these unexpressed genes are unselected and therefore directly reflect inherent mutation biases. Using a χ2 test, we have shown that the number of mutations in the CDRs is significantly higher than the number of mutations found in the FRs, providing direct evidence for the hypothesis that mutations are preferentially targeted into the CDRs.

Notizen: Abstract A new experiment is described to advance the mechanistic description of fast thermal decomposition chemistry related to preignition and ignition. The technique is illustrated with data for ethylenediammonium dinitrate which displays separable thermochemical events in the condensed phase that correlate with the nature of the products evolved to the gas phase.

Notizen: Abstract Pioneer 11 and 10 observations of the wave structure seen in a corotating interaction region at 2.5 AU on day 284 of 1973 and 8 days later at 5 AU reveal large-amplitude Alfvénic structures with many detailed correlations seen between their features at the two radial distances. Hodogram analysis suggests the dominance of near plane polarized, transverse Alfvénic mode fluctuations with periods between 2 min and one hour or more. Some wave evolution close to the Corotating Interaction Region (CIR) shock is noticed, but waves towards the centre of the compression seem to propagate with little damping between the spacecraft observation positions.
