Bracksteklar (Braconidae) är en familj bland parasitsteklarna. Det finns cirka 40000 kända arter i världen. Av dessa finns drygt 1100 arter i Sverige[1].

Kännetecken |


Bracksteklarna blir oftast mellan 2 och 15 millimeter långa. Framvingen har högst två tvärribbor i mittpartiet vilket skiljer dem från brokparasitsteklarna som har tre tvärribbor.



Levnadssätt |


Bracksteklarna lever som parasitoider på andra insekter. Framför allt larver och puppor av fjärilar, skalbaggar och flugor. Ofta läggs flera ägg i samma värddjur. Bracksteklarna (främst arter ur släktena Apanteles, Bracon och Opius) används vid biologisk bekämpning av skadeinsekter.

An IMO inspired problem

Image
14 4 This problem from IMO 1988 is said to be one of the most elegant ones in functional equations. Problem : The function $f$ is defined on the set of all positive integers as follows: begin{align} f(1) = 1, f(3) &= 3, f(2n) = f(n), \ f(4n+1) &= 2f(2n+1) - f(n), \ f(4n+3) &= 3 f(2n+1) - 2f(n) end{align} Find the number of $n$ with $f(n) = n, 1 leq n leq 1988$. The main idea towards the solution is realizing that these conditions stand for the fact that $f(n)$ just reverses the digits in the binary representation of the number $n$. So, essentially the solution is finding the number of binary pallindromes $leq 1988_{10}$. My question is the following : How to reformulate the problem so that $f(n)$ reverses the digits of $n$ in its ternary representation. Or even better, can we reformulate it for a

Has there ever been an instance of an active nuclear power plant within or near a war zone?

Image
36 3 The question Has there ever been a military combat going on around an active (running or in outage but not decommissioned) commercial nuclear power plant? Or dangerously near it? If yes, how did the plant and its personnel fare in such situation? Why I ask Let's assume for the scope of this question modern commercial nuclear power plants (CANDU, PWR, BWR of generation II plus all of gen III and newer) are usually reasonably safe to operate given that the engineering has been done right and there is a whole cohort of very well trained personnel on-site at all times, well rested and with considerable resources on their hands. Things hard to get with an armed conflict like the recent Syrian war raging around. I can't seem to find any reference or a comprehensive article about this, hence this question.
