Novel replacement policies that are hybrids of inspection maintenance and block replacement are developed for an n component series system in which the component parts used at successive replacements arise from a heterogeneous population. The heterogeneous nature of components implies a mixed distribution for time to failure. In these circumstances, a hybrid policy comprising two phases, and ea...

The present study demonstrates how, predominantly by external fiducials, histological serial sections used to reconstruct patterns of individually marked cellular events in large organs or whole embryos can be realigned with the help of "reference series". Resin-embedded embryos were cut at 1 microm and consecutive sections were alternately placed on two sets of slides. For cytological diagnosi...

Merozoite surface protein 1 (MSP1) of Plasmodium falciparum has been implicated as an important target of acquired immunity, and candidate components for a vaccine include polymorphic epitopes in the N-terminal polymorphic block 2 region. We designed a polyvalent hybrid recombinant protein incorporating sequences of the three major allelic types of block 2 together with a composite repeat seque...

Bio-fertilizers are naturally occurring soil bacteria that aggressively colonize plant roots and benefit plants by providing growth promotion. This investigation was aimed at determining the effect of Nitroxin bio-fertilizer application on growth, inoculation and yield production of corn hybrids. An experiment was conducted as split plot on the basis of randomized complete block design with fou...

The notion of dynamical consistency 3] is extended to hybrid systems so as to deene the set of dynamically consistent hybrid partition machines associated with a continuous system S. After the presentation of some basic results on the algebraic structure of discrete partition machines, dynamical consistency is deened for hybrid systems, and the lattice HIBC(S) of hybrid in-block controllable pa...

in order to compare the agronomic characteristics of developed iranian spring wheat genotypes (selective cultivars from: endemic landraces of wheat, interal hybrid wheat and international centers) and also the identifying traits affecting grain production under different concentration of iron in the soil solution, a randomized complete block design with a split-plot arrangement with 30 wheat ge...

Within the framework of the hierarchical hybrid control theory presented in 3], one may pose the following hybrid modelling problem: for a given nite state machine M, nd a state space X, a state space partition , and a controlled ODE system S on X such that the associated hierarchical hybrid partition machine M based upon S is a hybrid in-block controllable (HIBC) machine satisfying M = M. In t...
