The Indian Ocean humpback dolphin ( Sousa plumbea ) is “endangered” with likely less than 500 animals remaining in South African waters. Established 2016, the SouSA Consortium a formalised network of scientists and conservationists to combine knowledge research efforts, make coordinated decisions aim conserving species. first collaborative project collated available photo-identification data an...

Executing an action in response to a stimulus is thought to result in the creation of an event code that integrates stimulus and action features (Allport, 1987; Hommel in Visual Cognition 5: 183-216, 1998). When switching between tasks, competitor priming occurs if a distractor stimulus cues the retrieval of a previously established event code in which that distractor is bound to a competing ta...

We recently proposed a quantitative PCR procedure for the absolute measurement of c-erbB-2 oncogene amplification, based on the simultaneous polymerase chain reaction (PCR) amplification of the target gene and of a competitor DNA molecule acting as internal standard. To increase the number of assayable oncogenes and the accuracy of the quantitative comparison of gene amplification degree within...

To standardize a PCR assay for the detection of parvovirus B19 DNA in serum samples three different sample treatments were evaluated on the basis of the efficiency of recovery, reproducibility, convenience of sample handling, and presence of PCR inhibitors. Moreover, the presence of an internal standard competitor as the working reagent at one defined concentration in a competitive PCR-ELISA ha...

In a series of two studies, we explored people’s selection of self-promotion or competitor derogation when intrasexually competing for mates, as influenced by sex and romantic relationship involvement. In Study 1, student participants completed a forced-choice survey outlining six hypothetical competitive tactics. The findings indicated that self-promotion was chosen more often than competitor ...

Binary systems consisting of 1,2-dichlorobenzene (12DCB) + competitor were investigated over a range of concentrations of competitor in three natural sorbents with distinct characteristics. Two models, the ideal adsorbed solution theory (IAST) and the potential theory (Polanyi-based multisolute model), widely used in the prediction of multisolute sorption equilibrium from single-solute data, we...

Peptide analogues of disease-associated epitopes were studied for inhibition of experimental allergic encephalomyelitis (EAE) and adjuvant arthritis (AA) in Lewis rats. EAE- and AA-associated analogues were selected as competitors because of their in vitro inhibitory activity on proliferation of encephalitogenic and arthritogenic T cells. Although the EAE-associated competitor had a superior ma...

In studying the success of foraging animals, studies of interference competition have put emphasis on effects of competitor density, whereas studies of resource defense have focused on the effects of the spatial distribution of food within patches. Very few studies have looked at both factors simultaneously, that is, determined whether the effects of competitor density on foraging success depen...

This study develops a methodology to determine the optimal allocation position deploy bikes in competitive dockless bike sharing market. The community structure approach complex network theory is utilized offer strategies market leader two specific regimes, with potential competitor, and without competitor. Two different heuristics are proposed handle scenarios respectively due design objective...
