We show that for every computably enumerable (c.e.) degree aΒΏ0 there is an intrinsically c.e. relation on the domain of a computable structure of computable dimension 2 whose degree spectrum is {0; a}, thus answering a question of Goncharov and Khoussainov (Dokl. Math. 55 (1997) 55-57). We also show

An exact treatment of the initial field falling on the entrance face of a photoreceptor, so that the scattered field far from the latter vanishes, is presented. Its physical interest and some consequences are discussed. By establishing certain similarities between the behaviour of the photoreceptor
