Another side of new technologies

Everybody knows that new technologies today do not only make our life easier, sweeter, more secured and comfortable, they mainly show the economical, political, social development of the country. Every leading country tries to invent something absolutely new or redevelop old production in the way to show that this country has enough money, education and scientists. Nowadays we can not imagine our life without high-tech gadgets we use every day. We use them to communicate, to eat, to travel, to be healthy and so on. But in this very sphere we should adhere golden middle. Otherwise, novelties can turn against us

Про диференціальні нерівності С.А. Чаплигіна стосовно граничної задачі Коші для систем звичайних диференціальних рівнянь першого порядку

We prove a theorem on differential inequalities related to limit Cauchy problem for the set of ordinary differential equations$$y' = f(x,y,z),$$$$z' = \varphi(x,y,z)$$with boundary conditions$$\lim\limits_{x \rightarrow \infty} y(x) = y(\infty) = y_0, \; \lim\limits_{x \rightarrow \infty} z(x) = z(\infty) = z_0$$Доводиться теорема про диференціальні нерівності стосовно граничної задачі Коші для системи звичайних диференціальних рівнянь$$y' = f(x,y,z),$$$$z' = \varphi(x,y,z)$$з граничними умовами$$\lim\limits_{x \rightarrow \infty} y(x) = y(\infty) = y_0, \; \lim\limits_{x \rightarrow \infty} z(x) = z(\infty) = z_0$
