A review is given on the theoretical studies of charge correlations in θ-(BEDT-TTF)2X. Various studies show that within a purely electronic model on the θ-type lattice with on-site U and nearest neighbor Vp and Vc interactions, the diagonal stripe, c-axis three-fold, and the vertical stripe charge correlations are favored in the regime Vp Vc , respectively. In the realist...

We present de Haas-van Alphen (dHvA) measurements of the isostructural

We give a theoretical analysis of published experimental studies of the effects of impurities and disorder on the superconducting transition temperature Tc of the organic molecular crystals k-(BEDT-TTF)2X „where X5Cu@N(CN)2#Br and Cu(NCS)2 and BEDT-TTF is bis~ethylenedithio!tetrathiafulvalene... and b-(BEDT-TTF)2X ~for X5I3 and IBr2). The Abrikosov-Gorkov ~AG! formula describes the suppression ...

Polyploidy plays a major role in the evolution of angiosperms with multiple paleopolyploid events having been suggested making it plausible that all angiosperms have a polyploid event in their history. Polyploidy can arise by genome duplication within a species (i.e., autopolyploidy), or whole genome duplication coupled with hybridization (i.e., allopolyploidy). Penstemon subsection Saccanthera...

We have analyzed the mechanism of sex determination in the germ line of Drosophila by manipulating three parameters: (1) the ratio of X-chromosomes to sets of autosomes (X:A); (2) the state of activity of the gene Sex-lethal (Sxl), and (3) the sex of the gonadal soma. To this end, animals with a ratio of 2X:2A and 2X:3A were sexually transformed into pseudomales by mutations at the sex-determin...

and Applied Analysis 3 Definition 1.4. A sequence {xk} in an n-normed space X is said to converge to some x ∈ X in the n-norm if lim k→∞ ∥ ∥xk − x, y2, . . . , yn ∥ ∥ 0, 1.4 for every y2, . . . , yn ∈ X. Definition 1.5. A sequence {xk} in an n-normed space X is said to be a Cauchy sequence with respect to the n-norm if lim k,l→∞ ∥ ∥xk − xl, y2, . . . , yn ∥ ∥ 0, 1.5 for every y2, . . . , yn ∈ X...

Phaius tankervilleae and amboinensis orchids are decorative that have high ornamental value classified as endangered plants. Genetic information from the P. will be useful for plant breeders to develop a strategy in improvement program. The aim of study was determine karyotype pattern orchids. Chromosomes obtained meristematic root tips each species were used construct idiogram squash method. r...
