DNA methylation in plants affects transposon silencing, transcriptional regulation and thus phenotypic variation. One unanswered question is whether DNA methylation could be involved in local adaptation of plant populations to their environments. If methylation alters phenotypes to improve plant response to the environment, then methylation sites or the genes that affect them could be a target ...

He is responsible for all requisition, standardization, and CAD automation activities as well as detailed design of new products for centrifugal compressors, reciprocating compressors and turboexpanders both in Florence (Nuovo Pignone), Le Creusot (Thermodyn), and Oshkosh (AC). ...

Glucose transporter GLUT4 (also known as SLC2A4) plays a major role in glucose homeostasis and is efficiently retained intracellularly in adipocytes and myocytes. To simplify the analysis of its retention, here, various intracellular GLUT4 domains were fused individually to reporter molecules. Of the four short cytoplasmic loops of GLUT4, only the first nine-residue-long loop conferred intracel...

As part of the BIOSANT program (biologically-inspired smart nanotechnology), scientists at NASA-Langley have identified a “self-healing” plastic that spontaneously closes the hole left by the passage of a bullet. To understand and generalize the phenomenon in question, the mechanical properties responsible for this ability are being explored. Low-rate impression testing was chosen to characteri...

dermoid cysts are congenital anomalies derived from ectoderm. they are rare in head and neck region and especially in pinna. we presented an 8-year-old girl with a dermoid cyst in the conchal region of auricle which was treated with complete surgical resection.

some small gabbro patches emplaced along the thrust fault with w-e trend in the vicinity of maien bolagh village at the ht/mp metapelites, a part of the central iran zone (near to sanandaj-sirjan zone). the coarse-grained dark gabbro samples consist of amphibole, clinopyroxene, plagioclase, minor quartz, titanite, and biotite. gabbros have high potassic calc-alkaline to shoshonitic affinity. th...

The problem of steady, laminar and incompressible natural convection flow in an octagonalenclosure was studied. In this investigation, two horizontal walls were maintained at a constant hightemperature, two vertical walls were kept at a constant low temperature and all inclined walls wereconsidered adiabatic. The enclosure was assumed to be filled with a Bousinessq fluid. The studyincludes comp...
