background: gel polymers are considered as new dosimeters for determining radiotherapy dose distribution in three dimensions. objective: the ability of a new formulation of magic-f polymer gel was assessed by experimental measurement and monte carlo (mc) method for studying the effect of gold nanoparticles (gnps) in prostate dose distributions under the internal ir-192 and external 18mv radioth...

The body of knowledge on delusional parasites is incriminates “delusional patients” as having imaginary external and internal symptoms that feel like parasite movements, dismisses them as psychiatric cases, and confuses cause with effect. We are critical of these arguments and believe that the symptoms of crawling and pin-pricking are genuine; just misinterpreted as parasite movements. Based on...

Interspecific interaction may lead to species exclusion but there are several ways in which species can coexist. One way is by reducing the overall intensity of competition via aggregated utilisation of fragmented resources. Known as the 'aggregation model of coexistence', this system assumes saturation and an equilibrium number of species per community. In this study we tested the effects of i...

If so, then it is surprising to realize that research on social motivation usually deals with the nature of the proposed explanatory processes which are assumed to work similar across individuals, and it appears that very little research attention is devoted in this context to individual differences, even though they account probably for the majority of the variance of what research on social m...
