The roof garden has great functioning of smoothing the shortage of land resource in the city and making use of the land resource diversity and efficiently. The modern era, following the fast development of economic and society, people have a high claim to green roof or roof garden. It is an efficient and reasonable way to exploit the open space the roof of the building. From the classic roof ...

Increasing habitat fragmentation and human population growth in Africa has resulted in an escalation in human-elephant conflict between small-scale farmers and free-ranging African elephants (Loxodonta Africana). In 2012 Kenya Wildlife Service (KWS) implemented the national 10-year Conservation and Management Strategy for the Elephant in Kenya, which includes an action aimed at testing whether ...

We prove the Garden of Eden theorem for cellular automata with finite set of states and finite neighbourhood on right amenable left homogeneous spaces with finite stabilisers. It states that the global transition function of such an automaton is surjective if and only if it is preinjective. Pre-Injectivity means that two global configurations that differ at most on a finite subset and have the ...

We prove a converse to Myhill’s “Garden-of-Eden” theorem and obtain in this manner a characterization of amenability in terms of cellular automata: A group G is amenable if and only if every cellular automaton with carrier G that has gardens of Eden also has mutually erasable patterns. This answers a question by Schupp, and solves a conjecture by CeccheriniSilberstein, Mach̀ı and Scarabotti.

As previous years, Dip 5 will continue with the redefinition of what was formerly known as public space, trying to reactivate the physical realm of the common, nowadays kidnapped by economic and political agents. The origin of the word paradise gets back to ancient Persia, and to the Avestian term pairi-daêza, composed by pairi, "around" and diz "to construct", literally enclosed space, that wa...

Imagine you are walking across a field, when you see a fence in the distance, blocking your way. OK, you say, I can probably hop over it. But as you come nearer, you find that on the near side of the fence, and running parallel to it, is a deep ditch. From the bottom of the ditch, you realize, the top of the fence will be just too high to jump. What to do? For enzymatic reactions carried out by...

Using a fixed-speed test, burst swimming performance was found to vary among nine populations of emergent sockeye salmon Oncorhynchus nerka fry reared in a common-garden environment. No consistent relationship was, however, detected between difficulty of fry migration (upstream v. downstream) to rearing areas and total burst swimming duration or bursting rate.
