this study carried out in a factorial layout on completely randomaized block design with three replications, to evaluate the above- and below- ground competition between sesame (sesamum indicum) and pigweed (amaranthus retroflexus), and their impacts on sesame yield and yield component. the experimental treatments were all combination of crop-weed competition (shoot competition, root competitio...

the law of prohibition of unfair competition prohibits any deed or action which is against the normal competition in the market. before emergence of special laws for protection of intellectual property rights, including trademarks, such right could be protected either by tort law claims or law of unfair competition. however, the law of prohibition of unfair competition covers a wider area than ...

In many animals in which females store sperm, males may detect female mating status and, in order to outcompete rival sperm, increase ejaculate size when copulating with non-virgin females. Although most studies have been restricted to organisms with separate sexes, theoretical models suggest that sperm competition should also be an important selective agent shaping life-history traits in simul...

Competition plays an important role in structuring the community dynamics of phytophagous insects. As the number and impact of biological invasions increase, it has become increasingly important to determine whether competitive differences exist between native and exotic insects. We conducted a meta-analysis to test the hypothesis that native/ exotic status affects the outcome of herbivore comp...

The role of competition in healthcare is much debated. Despite a wealth of international experience in relation to competition, evidence is mixed and contested and the debate about the potential role for competition is often polarised. This paper considers briefly some of the reasons for this, focusing on what is meant by “competition in healthcare” and why it is more valuable to think about th...

An analysis of the SAT 2005 sub-competition on random instances is given. This year this (sub-)competition set-up was geared to establish a basic setting, focusing on the instances near the (infamous) “50% densities”, so first we have to establish a more quantitative understanding of phase transitions here. We present extended empirical results, clearly showing that the models used before, whic...
