How to fix a mosquito net metal sieve?
I've recently learned about Bitwise sieve. The only usefulness I can think of it is it can generate more primes than normal Sieve of Eratosthenes as it takes less memory. But I've never confronted a situation (only here - SPOJ TDPRIMES) where you can't solve it with the normal sieve, but solve it with bitwise sieve. My question is, how much it is useful for contests?

I have to shake my flashlight to get it to come on. can this be fixed
A common problem with torches and flashlights, especially led types of certain price ranges, especially those constructed of aluminium.
Most such torches use a push switch that has a point contact that soon becomes incapable of providing the perfect contact that is needed for low voltage low current applications. The materials used usually isn't the best for the job.
Aluminium casings are prone to oxidisation which is an electrical insulator.
Whether it can be fixed depends on how far it can be dismantled, the design and how handy you are.
A torch should ideally have a switch with a wiping or self-cleaning action and be hard wired with high quality nickel-plated brass or copper internal components.
It is many decades since such a torch was generally available at reasonable prices so a compromise might be made by spraying the inside of a new torch with a silicone spray or WD-40 and repeating whenever the batteries are replaced.

What are the benefits of sports camps?
The physical benefits kids achieve with athletic activity, such as cutting the risk of obesity, diabetes, heart disease and social and psychological benefits of getting involved in athletics while in school. The ratio of coaches to athletes is always a plus. Most youth sports only have money for one coach, but professional camps like organizers have a skilled coach for playing and training children in Camps for Youths in your Area

How do I use the mosquito repellent function on my home well misting fun?
According to Joseph Conlon, a medical entomologist and technical advisor to the American Mosquito Control Association, mosquito season is already bad - and West Nile Virus, which is most commonly transmitted by the pesky insects, doesn't even really kick in until late summer. Plus, studies have found that certain types of mosquitoes are more likely to snack on pregnant women.
"Pregnant women may be more attractive to mosquitoes," Conlon says. "If the pregnant female is breathing more due to carting about a bit of extra weight, then she will also be a bit more attractive to mosquitoes, because mosquitoes are attracted to carbon dioxide." Plus, pregnant women have a warmer average body temperature, which is a cue for biting and landing, he adds.
So use mosquito repellent for baby and also during pregnancy
