Nowadays, a high incidence of cutaneous tumors is observed in domestic carnivorous in pet clinic, the sebaceous glands being the starting point for the development of these tumors. The hormonal imbalances are considered to be the most common etiology for these tumors, so the current research is based on the effects of an androgenic like hormonal drug on the functionality of the sebaceous glands in dogs. For this purpose, 32 dogs were distributed in 4 groups: control group 1 (8 dogs - females), control group 2 (8 dogs - males), experimental group 1 (8 dogs - females) and experimental group 2 (8 dogs - males).
The investigation targeted the pH of skin and the rate of sebum’s secretion. The animals from the experimental groups were treated with Anabolin forte for 2 days at a dose of 1 mg/kg body weight/day, intramuscular.
The obtained results revealed that administration of Anabolin forte in males induced a significantly distinct intensification (with 10.66%) of sebum’s secretion and a significant decrease of pH of the skin (with 17.1%) compared to the animals from the control group. The administration of Anabolin forte in females induced a significantly distinct intensification (with 17.47%) of sebum’s secretion and a significant decrease of the pH of the skin (with 14.32%) compared to the animals from the control group.

Noise control has gained a lot of attention recently. However, presence of nonlinearities in signal paths for some applications can cause significant difficulties in the operation of control algorithms. In particular, this problem is common in structural noise control, which uses a piezoelectric shunt circuit. Not only vibrating structures may exhibit nonlinear characteristics, but also piezoelectric actuators. In this paper, active device casing is addressed. The objective is to minimize the noise coming out of the casing, by controlling vibration of its walls. The shunt technology is applied. The proposed control algorithm is based on algorithms from a group of soft computing. It is verified by means of simulations using data acquired from a real object.

Cephus fumipennis Eversmann is a key insect pest of wheat crops in Qinghai, China. Its field population densities were surveyed by using both the back-loaded insect vacuum and a sweep net. Mean densities in township-level were calculated and a quantitative relation, ŷ = 0.664 + 0214x, was established between the two sampling methods. The empirical relationship may be applicable in density monitoring and Integrated Pest Management program of the insect.
