This research was conducted over a period of one year from the beginning of spring until mid autumn in 1996, during the bloom of all flowering plants in the region, when pollinator bees were collected with insect veil. Some of them were preserved in 80% ethylalcohol and some were dried, coded, kept in insect box and transferred to the laboratory for identification. The collected insects were id...
A set D of vertices in a graph G is disjunctive dominating if every vertex not adjacent to or has at least two distance 2 from it . The domination number, γ d ( ), the minimum cardinality We show that T tree order n with l leaves and s support vertices, then n-l +3/4≤ )≤ n+l +s/4. Moreover, we characterize families trees which attain these bounds.
OBJECTIVE To determine if children aged 1-6 years from non-Western immigrant families have lower serum 25-hydroxyvitamin D (25(OH)D) levels than children from Western-born families and examine which factors influence this relationship. DESIGN Cross-sectional study. SETTING Toronto, Canada. SUBJECTS Healthy children (n 1540) recruited through the TARGet Kids! practice-based research networ...

We investigate the low-lying zeros in families of L-functions attached to quadratic and cubic twists elliptic curves defined over Fq(T). In particular, we present precise expressions for expected values traces high powers Frobenius class these with a focus on lower order behavior. As an application obtain results one-level densities verify that curve have orthogonal symmetry type. twist our ref...
Let ? be a weight function defined on locally compact group G, 1?p<+?, S?G and let us assume that for any s?S, the left translation operator Ts is continuous from weighted Lp-space Lp(G,?) into itself. For given set ??C, vector f?Lp(G,?) said to (?,S)-dense if {?Tsf:???,s?S} dense in Lp(G,?). In this paper, we characterize existence of vectors terms ?.
Recently, a generalized ranked set sampling (RSS) scheme has been introduced which encompasses several existing RSS schemes, namely varied L (VLRSS), and it provides more precise estimators of the population mean than with traditional simple random (SRS) schemes. In this paper, we extend work consider maximum likelihood (MLEs) location scale parameters when from location-scale family distributi...
