Filamentous fungi of the Aspergillus niger group are native soil saprophytic fungi. Industrial strains of this group have been extensively used for the production of plant degrading enzymes for the food and beverage, animal feed and paper-and-pulp industries. Recombinant DNA technology allows for the overproduction of these enzymes in copious amounts. The advantages and limitations of A. niger ...

The expectation and the mean of partitions generated by a cluster ensemble are not unique in general. This issue poses challenges in statistical inference and cluster stability. In this contribution, we state sufficient conditions for uniqueness of expectation and mean. The proposed conditions show that a unique mean is neither exceptional nor generic. To cope with this issue, we introduce homo...

The protein glutaredoxin, required for GSH-dependent ribonucleotide reduction, has been purified to homogeneity from calf thymus. The preparative method consisted of ammonium sulfate precipitation and three chromatography steps on DEAEkellulose, Sephadex G-50, and CM-Sepharose. Calf thymus glutaredoxin was assayed on the basis of its inherent GSH-disulfide transhydrogenase activity. Glutaredoxi...

Electronics and soft robotics demand the development of a new generation hybrid materials featuring novel properties. Among these, remarkable mechanical properties are required to sustain stresses, electrical magnetic essential design devices’ interface. In this study, material is presented, consisting spider silk thread, providing robustness, coated with layer magnetostrictive FeCo alloy, whic...

Abstract This article explores the shifting connotations of two key terms in propaganda texts on bilingual education policy Inner Mongolia. The are dumdadu-yin ündüsten (Ch.: Zhonghua minzu , Chinese nation) and ulus-un neidem hereglehü üge hel guojia tongyong yuyan national common language). I examine how meanings these have begun to shift as China strives shed its multinational character buil...

An orthophosphate-repressible acid phosphatase from a wild type strain of Neurospora crassa was purified to apparent homogeneity. The degree of purity was ascertained on the basis of chromatographic, electrophoretic, and centrifugal data. Sedimentation equilibrium analyses indicated the native molecule has a molecular weight of about 85,000 and can be dissociated in the presence of 6 M guanidin...
