Seventeen non-directed td- (thymidylate synthase-deficient) splicing-defective mutations isolated in phage T4 were localized within the catalytic core of the ribozyme. All of the mutations occur in conserved structural elements that form part of the td intron core secondary structure. Remarkably, seven of the seventeen independently isolated mutations clustered in the dinucleotide 5' element (P...

Outer membrane protein P6 is the subject of investigation as a vaccine antigen to prevent infections caused by nontypeable Haemophilus influenzae, which causes otitis media in children and respiratory tract infections in adults with chronic lung disease. P6 induces protective immune responses in animal models and is the target of potentially protective immune responses in humans. P6 is a 16-kDa...

Let G be a finite undirected graph. A vertex dominates itself and all its neighbors in G. A vertex set D is an efficient dominating set (e.d. for short) of G if every vertex of G is dominated by exactly one vertex of D. The Efficient Domination (ED) problem, which asks for the existence of an e.d. in G, is known to be NP-complete even for very restricted graph classes such as P7-free chordal gr...

An investigation was carried out to determine the morpho-physical status of soils Kanamadi South sub- watershed in Karnataka state India. A detailed soil survey sub using IRS P6 LISS-IV image and a total ten pedon location which were well distributed sub-watershed selected. The shallow deep. Colour pedons varied from 10 YR 2/1 (black) 4/3 (brown). Soil texture clay loam, having loose moderately...

The purpose of this study was to characterize the degree of antigenic heterogeneity or conservation of a 16,600-dalton outer membrane protein (P6) among strains of nontypable Haemophilus influenzae. Immunization of rabbits with P6 isolated from individual strains resulted in antibody to P6 of all 25 strains tested. The titers of antibody in the sera were similar among the strains. Whole organis...

Changes in shoreline configurations accelerated due to global warming are world wide concern. Such changes not only affect the flora and fauna of those regions but also the livelihood of the coastal population. In the context, the 7517km long coastline of Indian coast behaves differently in different regions. Therefore, in order to assess the shoreline changes taking place in particular coastal...

Imagine that you have 6 people at a party. We assume that, for every pair of them, either THEY KNOW EACH OTHER or NEITHER OF THEM KNOWS THE OTHER. So we are assuming that if x knows y, then y knows x. Claim: Either there are at least 3 people all of whom know one another, or there are at least 3 people no two of whom know each other (or both). Proof of Claim: Let the people be p1, p2, p3, p4, p...
