The Notch locus is one of the best characterized loci in Drosophila melanogaster in terms of its genetic structure and developmental effects. Mutations in this locus profoundly affect the differentiation of the early embryo. Using an inversion involving the Notch locus and previously cloned sequences, we have isolated chromosomal segments from the Notch region (3C7) encompassing 80 kilobases (k...

We employ a detailed restriction fragment length polymorphism (RFLP) map to investigate chromosome organization and evolution in cotton, a disomic polyploid. About 46.2% of nuclear DNA probes detect RFLPs distinguishing Gossypium hirsutum and Gossypium barbadense; and 705 RFLP loci are assembled into 41 linkage groups and 4675 cM. The subgenomic origin (A vs. D) of most, and chromosomal identit...

The present investigation was designed to study the production and comprehension of specific means for information highlighted by advanced Iranian learners of English as a Foreign Language. The study focused on the discourse-pragmatically motivated variations of the basic word order such as inversion, pre-posing, it- and Wh-clefts. After taking the Nelson test, a homogeneous group was settled. ...

Equatorial/axial conversion in piperidine and phosphorinane with different substituents wereinvestigated with great details. Three possible routes, i.e. heteroatom inversion and two ring inversiontype were considered. Ring conversion can occur via two pathways one starts with ring flatteningfrom the heteroatom site (nitrogen in piperidine and phosphorous in phosphorinane) and the otherinitiates...

Airborne electromagnetic (AEM) surveys carried out around the globe produce thousands of km of data every year. Because of the enormous computational costs involved in a full 3D inversion, these data are usually inverted using a 1D forward model. The 1D model assumption is legitimate in quasi layered sedimentary areas. In some cases the output models are simply stitched together (Auken et al., ...

Polyacrylonitrile nanofibrous tubular structures were produced through typical and opposite charge electrospinning methods and the effect of the method as well as the two key electrospinning parameters, namely concentration of the electrospinning polymer solution and rotational speed of mandrel collector on properties of such tubular structures were studied. The smples were characterized by...

Captopril is one of the most significant angiotensin-converting enzyme inhibitors. In spite of numerous experimental and computational studies on its properties, not enough geometrical and thermodynamic data is available on this compound. So, this study aimed to investigate the structural properties and assignment of possible conformers of captopril in the gas-phase. To this end, 1152 unique tr...

SUMMARY The inversion of electromagnetic induction data to a conductivity profile is an ill-posed problem. Regularization improves the stability and smoothing constraint typically used. However, profiles are not always expected be smooth. Here, we develop new scheme in which transform model wavelet space impose sparsity constraint. This constrained will minimize objective function with least-sq...

Chromosomal inversion polymorphism affects nucleotide variation at loci associated with inversions. In Drosophila subobscura, a species with a rich chromosomal inversion polymorphism and the largest recombinational map so far reported in the Drosophila genus, extensive genetic structure of nucleotide variation was detected in the segment affected by the O(3) inversion, a moderately sized invers...
