Project planning is part of project management, which is relates to the use of schedules such as Gantt charts to plan and subsequently report progress within the project environment. Initially, the project scope is defined and the appropriate methods for completing the project are determined. In this paper a new approach for the critical path analyzing a project network with random fuzzy activi...

The seeds of lettuce (Lactuca sativa L. cv. Grand Rapids) germinate in darkness at 25 C when treated by gibberellic acid (GA(3)) for 1 hour following 2 hours of imbibition. The time of GA(3) application influences the rate and the final percentage of seeds that germinate. In contrast, red light illumination given at different times affects only the rate and not the final germination percentage....

Ficus religiosa has great mythological, religious, and medicinal importance in the culture of India and Nepal since times immemorial. The present paper was done to evaluate the potential of sodium hypochlorite in controlling the contamination of F. religiosa micro-propagation and seed germination of F. religiosa. In this study, a factorial experiment based on a completely randomized design with...

Earlier reports have indicated that the pollen of Eucalyptus is mechanically robust and unusually resistant to the osmotic stress imposed by immersion in water. We have investigated some of the features of the germination mechanism in the pollen of E. rhodantha with a view to clarifying the role of pollen-wall specializations in determining this resistance. Cultured in vitro, the pollen showed ...

Houses are at once built shelters; collections of relations, affects, and moralities; nodes within neighborhoods, communities, larger political-economic environmental regimes. This Colloquy proposes oikography as an ethnographic approach that deconstructs technocratic assumptions about the house traces plasticity dwelling across multiple space-times, with a focus on action house-ing. Inspired b...

The micropylar endosperm is a major regulator of seed germination in endospermic species, to which the close Brassicaceae relatives Arabidopsis thaliana and Lepidium sativum (cress) belong. Cress seeds are about 20 times larger than the seeds of Arabidopsis. This advantage was used to construct a tissue-specific subtractive cDNA library of transcripts that are up-regulated late in the germinati...

Salinity is one of the environmental stresses limiting rice cultivation. Evaluation of the tolerance and sensitivity of offsprings of segregated generations under salinity condition is one way of finding tolerant cultivars. In order to study the effects of salinity (80 mM NaCl) stress on the second generation offspring of crosses of three rice varieties (Dollars and Gharib with 304) and to comp...

Salinity is one of the striking problems in agricultural production many parts world. Seed germination and seedling growth are two critical stages for establishment crops generally most sensitive to salt stress. The present study aimed at evaluating initial pepper seedlings produced from seeds under different soaking times NaCl solutions. experiment was carried out a completely randomized desig...

Vary, J. C. (University of Wisconsin, Madison), and H. O. Halvorson. Kinetics or germination of Bacillus spores. J. Bacteriol. 89:1340-1347. 1965.-The kinetics of germination of Bacillus cereus strain T spores was accurately described by McCormick. To study the mechanism of germination, it is necessary to correlate the characteristic changes in a population of germinating spores with the behavi...
