The book is devoted to the theory of development of the biological systems.

The fundamental equation of life of a biological population, based on the general physical principles, allows us to get all the basic equations of population dynamics, describing the development of the populations under various environmental conditions.

The equations describe the population transition that occurred in our human population in the late 20-th century. This transition may indicate the fact that the human population consists of two super-races Ð the old ÓslowÓ race, and new fast-growing human race that appeared on Earth relatively recently.

The separate chapter presents the base classification of predator-prey systems. The classification consists of ninety-six different equation systems.

The book is addressed to a broad auditorium of biologists, ecologists, and demographers, as well as readers, interested in the development of the biological populations.

Translated from Russian.

My Heels Were in Bad Shape. Like… Really Bad
Color: Gray
These moisturizing heel socks with the gel cushions were honestly a small miracle for me. After recovering from cancer treatments, my skin became extremely dry everywhere, but my heels were the worst. They cracked so deeply they looked like fissures and were even bleeding. I tried lotions and bandages repeatedly with very little progress. A friend suggested I treat my heel like it might have a fungal component, so I applied Lotrimin cream, put these heel socks on, and hoped for the best. Within three days, my heels were fully healed. I completed a 7-day routine, and my feet have never been softer. The silicone gel cushion is comfortable, soothing, and stays in place. I loved it so much that I still treat myself about once a week, even though I really don’t need to anymore. They are also washable. I hand-washed mine in the sink and let them air dry, and they came out looking brand new. If your heels are cracked, painful, or need serious care, I highly recommend these.

Ehh. Not for me.
Color: Gray
Foot slides when walking in them. The fit was tighter than lead to believe. It did hold the moisture in but the silicone patch is small
