To the Editor: We read with interest the innovative paper by Leveille and colleagues (1) discussing a new taxonomy of disability based on the most frequent self-reported symptoms. We agree with the authors that chronic disability in the older population has a multifactorial nature and it is difficult to ascertain a single cause. However, participants with moderate-to-severe cognitive impairment...

this study was conducted during two years (2007-2009) in shawoor agricultural research station on a silty-clay soil. experiment conducted in split plots in a randomized complete blocks design in three replications. main plots were planting methods including centrifugal broadcaster (p1), centrifugal broadcaster + furrower (p2), seed drill (p3), seed drill + furrower (p4), three lines bed drillin...

A graph G is called H-equicoverable if every minimal H-covering of G is also a minimum H-covering of G. In this paper, we investigate the characterization of P5-equicoverable graphs which contain cycles with length at least 5 and give some results of Pk-equicoverable graphs. Key–Words: P5-equicoverable,Pk-equicoverable,cycle,covering

Zverovich [Discuss. Math. Graph Theory 23 (2003), 159–162.] has proved that the domination number and connected domination number are equal on all connected graphs without induced P5 and C5. Here we show (with an independent proof) that the following stronger result is also valid: Every P5-free and C5-free connected graph contains a minimum-size dominating set that induces a complete subgraph.

We provide a certifying algorithm for the problem of deciding whether a P5-free graph is 3-colorable by showing there are exactly six finite graphs that are P5-free and not 3-colorable and minimal with respect to this property.

A well-known conjecture asserts that smooth threefolds X ⊂ P5 are quadratically normal with the only exception of the Palatini scroll. As a corollary of a more general statement we obtain the following result, which is related to the previous conjecture: If X ⊂ P5 is not quadratically normal, then its triple curve is reducible.

INTRODUCTION The expression of substance P (SP) receptor (neurokinin 1, NK1) was studied in the rat corpus callosum (cc) from postnatal day 0 (the first 24 hr from birth, P0) to P30. METHODS We used immunocytochemistry to study the presence of intracallosal NK1-immunopositive neurons (NK1IP-n) during cc development. RESULTS NK1IP-n first appeared on P5. Their number increased significantly ...

Voltage-gated Na(+) channel (VGSC) β1 subunits, encoded by SCN1B, are multifunctional channel modulators and cell adhesion molecules (CAMs). Mutations in SCN1B are associated with the genetic epilepsy with febrile seizures plus (GEFS+) spectrum disorders in humans, and Scn1b-null mice display severe spontaneous seizures and ataxia from postnatal day (P)10. The goal of this study was to determin...

The adeno-associated virus (AAV) inverted terminal repeats (ITRs) contain the AAV Rep protein-binding site (RBS) and the terminal resolution site (TRS), which together act as a minimal origin of DNA replication. The AAV p5 promoter also contains an RBS, which is involved in Rep-mediated regulation of promoter activity, as well as a functional TRS, and origin activity of these signals has in fac...

The purpose of this study was to gain insight into the control strategy that humans use in jumping. Eight male gymnasts performed vertical squat jumps from five initial postures that differed in squat depth (P1-P5) while kinematic data, ground reaction forces, and electromyograms (EMGs) of leg muscles were collected; the latter were rectified and smoothed to obtain SREMGs. P3 was the preferred ...
