Microbes are tiny creatures that live in and on our bodies. Many of them, especially those the gut, help to keep us healthy. Sometimes, when we eat spoiled food or take antibiotics, wipe out many these good microbes. Usually, microbes recover from disturbances, but sometimes harmful can their place cause disease. Clostridioides difficile is a microbe causes severe diarrhea. antibiotics kill C. ...

Minesweeper is a popular single-person game that was invented in the 1970’s (Figure 1). A fixed number N of mines are randomly placed on a W ×H grid and are hidden from the player. The game begins with an empty field. The player opens (via clicking) one square at a time. If the square contains a mine then the player blows up and the game is over. Otherwise the square becomes uncovered containin...

The church is a spiritual institution in which believing man fulfills his needs and, accordingly to that, he builds being. consists of the clergy and people. Without faithful people there no Church. And therefore, everything that concerns Church people; vice versa, all people, it In territory clero-fascist Independent State Croatia (NDH), persecution, terror killing were burned Serbs killed not...

of leprosy. On the same page another proposition is put forward, namely, that the bacillus of leprosy is, like that of tuberculosis, well nigh ubiquitous, and that it assumes activity under the stimulus of some ingredient supplied by fish in an early stage of decomposition ; having once assumed such activity, it can reproduce itself indefinitely in the tissues of the human body, and may be tran...

The method of descent is a technique developed by Fermat for proving certain equations have no (or few) integral solutions. The idea is to show that if there is an integral solution to an equation then there is another integral solution which is smaller in some way. Repeating this process and comparing the sizes of the successive solutions leads to an infinitely decreasing sequence a1 > a2 > a3...

The initial-boundary value problem for the nonlinear heat equation u, = Au + Xf(u) might possibly have global classical unbounded solutions, u* = u(x, r; uS), for some "critical" initial data u*. The asymptotic behaviour of such solutions is studied, when there exists a unique bounded steady state w(x,A) for some values of L We find, for radial symmetric solutions, that u*(r,t)-*w{r) for any 0 ...
