At present, depressive disorders affect a considerable proportion of population, their incidence showing an increasing tendency in the developed world. Depression mostly afflicts people in the age of 25-35. It occurs in females twice as often as in males. Depression involves an intense subjective suffering accompanied with a disruption of normal everyday functioning. Moreover, when compared with the healthy population, there exists a thirty times higher danger of suicide in the people affected with depression. The illness unfortunately tends to become chronic, the probability of recurrence of an episode being 50%. Furthermore, some patients suffering from the depressive disorder do not adequately respond to an antidepressant therapy; we call such patients treatment-resistant. There certainly exists a close relation between the endocrine and the central nervous system, most endocrine disorders being potentially accompanied with changes of psyche and vice versa. With affective disorders the most frequently reported disruption involves an interference with the function of the hypothalamicpituitary- adrenocortical (HPA) axis, though various studies repeatedly acknowledged also deviations of the hypothalamic-pituitary-thyroid (HPT) axis. The most frequent findings comprise an altered serum thyrotropin response...

Lagrange function in Newtonian and relativistic mechanics
Höschl, Cyril
The modification of Lagrange function is explicated, which is enforced by the requirement of Lorentz-invariance. The consequences of this step are shown. The paper is intended to commemorate two anniversaries regarding Albert Einstein, namely 100 years since the first publication concerning the special theory of relativity and 50 years since the death of this great physicist.

Making use of tensometry for investigation of failure causes
Höschl, Cyril
The utilization of tensometric measurements for detection of causes of machine failures will be demonstrated in two examples. The first one is theoretical; it is concerned with the search for maximum stress in a pressure vessel. The problem cannot be successfully solved without knowledge of the theory of shells. The second one deals with a problem of screw fatigue failures at a flange connecting the journal with the body of an elbow water turbine with horizontal shaft at a hydro-electric power plant in Prague.

Solving of Schrodinger's equation by finite element method
Höschl, Cyril
Numerical solution of electronic structures can be obtained using finite element method. Starting with a variational principle, the author derives the matrix form of discretized Schrodinger equation. Two examples demonstrate the correctness of the derived formula. Possible difficulties in solving real problems are shortly discussed.
