A population craniometric analysis of the red deer (Cervus elaphus L.) from Bulgaria was carried out using 19 linear skull and dental parameters. The analysis included 93 adult individuals (74 males and 19 females), originating from the main hunting economic areas in the country, i.e. Central Stara Planina Mountains, Strandzha-Sakar area, Ludogorie-Dobrudzha region and the Rila-Pirin region.

We present three attacks on the Prime Power RSA with modulus N = pq. In the first attack, we consider a public exponent e satisfying an equation ex − φ(N)y = z where φ(N) = pr−1(p − 1)(q − 1). We show that one can factor N if the parameters |x| and |z| satisfy |xz| < N r(r−1) (r+1)2 thereby extending the recent results of Sakar [16]. In the second attack, we consider two public exponents e1 and...
