We consider the following three problems: 1. Let U be a q-subset of GF(q 2) with the properties 0; 1 2 U and u ? v is a square for all u; v 2 U. Does it follow that U consists of the elements of the subbeld GF(q)? Here q is odd. 2. Let f : GF(q) ! GF(q) be any function, and let be the set of diierence quotients (directions, slopes). What are the possibilities for jD f j? 3. Let B be a subset of...

Fish possess two separate systems for detection of low-level sound and water motions in the low-frequency range: the inner ear and the lateral line. The relative roles of these systems in normal fish behaviour is still not clear. There is, for instance, a lack of experimental evidence showing the involvement of the lateral line and the inner ear in detection of infrasound, in directional hearin...

background: considering differences in head size and shape of different equine breeds, biometric parameters can be an attribute to a particular race. objectives: the purpose of the present paper is to give a numerical definition of morphological characteristics of head region of the darehshori horse. methods: twenty mature darehshori horses were studied biometrically. the ear length, ears dista...

Endogenous expression of antisense RNA in transfected cells has been explored for use in blocking cellular gene expression and for its antiviral potential. Antisense strategies were used with the goal of blocking measles virus (MV) infection. A recombinant expression plasmid was designed to produce antisense oligonucleotides targeted to the 5' end of the MV nucleocapsid protein mRNA. This const...
