We examined nitrate assimilation and root gas fluxes in a wild-type barley (Hordeum vulgare L. cv Steptoe), a mutant (nar1a) deficient in NADH nitrate reductase, and a mutant (nar1a;nar7w) deficient in both NADH and NAD(P)H nitrate reductases. Estimates of in vivo nitrate assimilation from excised roots and whole plants indicated that the nar1a mutation influences assimilation only in the shoot...

Sulphate assimilation is an essential pathway being a source of reduced sulphur for various cellular processes and for the synthesis of glutathione, a major factor in plant stress defence. Many reports have shown that sulphate assimilation is well co-ordinated with the assimilation of nitrate and carbon. It has long been known that, during nitrate deficiency, sulphate assimilation is reduced an...

Object-oriented (OO) technology was expected to rapidly replace traditional functional software technology due to its productivity and quality improvement potential in software development. Still, OO technology is not yet fully understood and utilized by information systems (IS) organizations. Despite the growing interest and attention of the IS researchers and practitioners, empirical research...

Two parallel acoustic analyses were performed for French and English sibilant sequences, based on comparably structured read-speech corpora. They comprised all sequences of voiced and voiceless alveolar and postalveolar sibilants that can occur across word boundaries in the two languages, as well as the individual alveolar and postalveolar sibilants, combined with preceding or following labial ...

This paper investigates the impacts of assimilating measurements of different state variables, which can be potentially available from various observational platforms, on the cycled analysis and short-range forecast of supercell thunderstorms by performing a set of observing system simulation experiments (OSSEs) using a storm-scale three-dimensional variational data assimilation (3DVAR) method....

Many techniques have been proposed for the recognition of Iris. Most them are single resolution which results in poor performance. In this paper, feature extraction approaches like local binary pattern and principal component analysis assimilation has offered. For classification, Support Vector Machine used. This paper compares efficiency two popular methods Principal Component Analysis Local B...

This article gives a detailed quantitative account of Samoan root phonotactics. In particular, count data is given in eleven tables of segment frequencies (i.e., consonants, short and long vowels, diphthongs) and frequencies of combinations of segments (i.e., syllable types, consonant-vowel combinations, V-V and C-C combinations across syllables). Systematic patterns of overand under-representa...

This study presents an acoustic analysis of the citation tones and tone sandhi patterns of bisyllables in Zhenjiang dialect with an attempt to provide an empirical data for the theoretical study of tone sandhi patterns of Zhenjiang dialect. The results demonstrate that this dialect has five citation tones, i.e., Tone1 (42), Tone2 (35), Tone3 (32), Tone4 (55) and Tone5 (5). The acoustic realizat...

Relying on its partisan principles and values, the Ba’athist regime– the period when Saddam Hussein was in charge in Iraq– sought a powerful government. Not respecting and believing in ethnical and sectarian differences and seeking the realization of national unity, Saddam tried to regulate security policies in a way in which he could assimilate the differing Iraqi society, using the policies o...

This paper argues for a particular understanding of feature class behavior the recurrent patterning together of certain phonological features, such as place of articulation and laryngeal features. The proposals build on the well known work of Feature Geometry in assuming the importance of feature classes in phonology, but differ in that features of a class are targeted directly and invidually b...
