Investigations of (1,3-Dimethyl-3-methylsilamethylene - disilacyclobutane) as a Single Source CVD Precursor to Silicon Carbide
The low pressure chemical vapor deposition (LPCVD) of silicon carbide from (CH3)HSiCH2SiCH2 (CH3)CH2 SiH2 (CH 3) on Si(100) has been investigated between 700 and 1100°C at ca. 1.0 torr total pressure using a flow...

Developmental patterns of aluminum and five essential mineral elements in the central nervous system of the fetal and infant guinea pig
Al is found in the develo** conceptus, but little information is available concerning its tissue distribution and its changes in concentration with age. Because Al has affinity for many of the same biologica...

Changes in late-embryogenesis-abundant (LEA) messenger RNAs and dehydrins during maturation and premature drying ofRicinus communis L. seeds
InRicinus communis L. (castor bean) endosperms, two classes of Late Embryogenesis Abundant (Lea) transcripts were first detected during mid-development (at 30–35 days after pollination, DAP) and peaked at 50 DAP,...

Symmetric orthonormal scaling functions and wavelets with dilation factor 4
It is well known that in the univariate case, up to an integer shift and possible sign change, there is no dyadic compactly supported symmetric orthonormal scaling function except for the Haar function. In thi...

Construction of multivariate biorthogonal wavelets with arbitrary vanishing moments
We present a concrete method to build discrete biorthogonal systems such that the wavelet filters have any number of vanishing moments. Several algorithms are proposed to construct multivariate biorthogonal wa...

Dentinogenesis imperfecta 1 with or without progressive hearing loss is associated with distinct mutations in DSPP
Dentinogenesis imperfecta 1 (DGI1, MIM 125490) is an autosomal dominant dental disease characterized by abnormal dentin production and mineralization. The DGI1 locus was recently refined to a 2-Mb interval on 4q2...

An F-box gene linked to the self-incompatibility (S) locus of Antirrhinum is expressed specifically in pollen and tapetum
In many flowering plants, self-fertilization is prevented by an intraspecific reproductive barrier known as self-incompatibility (SI), that, in most cases, is controlled by a single multiallelic S locus. So far, ...

TheVER2 promoter contains repeated sequences and requires vernalization for its activity in winter wheat (Triticum aestivum L.)
Previously, we isolated a vernalization-related gene,VER2, from winter wheat (Triticum aestivum L.) and its expression was restricted in the immature leaves of vernalized wheat seedlings. To further investigate t...
