Chartrand et al. (2004) have given an upper bound for the nearly antipodal chromatic number ac′(Pn) as (n−2 2 ) +2 for n > 9 and have found the exact value of ac′(Pn) for n = 5, 6, 7, 8. Here we determine the exact values of ac′(Pn) for n > 8. They are 2p − 6p + 8 for n = 2p and 2p − 4p + 6 for n = 2p + 1. The exact value of the radio antipodal number ac(Pn) for the path Pn of order n has been ...

Water stress is one of the major abiotic stresses in agriculture worldwide. In order to assess photosynthesis response and grain yield of 25 wheat genotypes under water deficit (post-anthesis stress) conditions, a 2-year study (2010-12) was carried out as a split-plot arrangement using randomized complete block design with three replications. The most sensitive gas exchange variable to water de...

A PPLICATIONS of electronic computers .in analysis of medical and biological data are of increasing interest. Large-scale computers offer the advantages of high speed of operation, relatively great accuracy, and extreme versatility. Great amounts of data can be processed in a relatively short time. Thus, extensive statistical studies, mass screening of the population, and data handling in large...

purpose: to assess the effect of emla® cream application without occlusive dressing on pain on needling (pn) and pain on injection (pi) felt during multiple botulinum toxin type a (bta) injections for correction of hyperkinetic upper facial lines methods: a prospective, randomized, double-blind, placebo-controlled clinical trial was conducted on 44 subjects seeking upper facial wrinkles correct...

clericuzio-type poikiloderma with neutropenia (pn) is characterized by poikiloderma, non-cyclic  neutropenia,  recurrent  sinopulmonary  infections,  pachyonychia,  and  palmo- plantar hyperkeratosis. mutations in the c16orf57 gene, which is located on chromosome 16q13, have been identified as the cause of pn. pn was first described by clericuzio in navajo indians. herein, we reported the clini...

The synthesis and characterization of new zirconium permethylpentalene (form)amidinate complexes are described: Pn*Zr{N(Dipp)2CH}Cl (1), Pn* = ?8-C8Me6 Dipp 2,6-iPr-C6H3; [Pn*Zr{N(p-tol)2CH}Cl]2 (2), p-tol 4-Me-C6H4; [Pn*Zr{N(iPr)2CMe}Cl]2 (3); Pn*Zr{N(iPr)2CPh}Cl (4); Pn*Zr{N(4-Me-C6H4)2CH}2 (5); [Pn*Zr{N(iPr)2CCH2}]2 (6); Pn*Zr{N(iPr)2CPh}(O-2,6,-Me-C6H3) (7). monohalide derivatives 1–4 demon...

Variance of opinion among authors regarding the cause and duration of each succeeding portion of the P-R interval points out that knowledge regarding the physiologic basis for these waves is incomplete. Data regarding the P-R segment are scant in electro-cardiographic literature. The necessity for precision in measurement and the need for better visualization of electrocardiographic waves to en...
