Can search dogs detect cannabis laced edibles?
The answer to your question will depend on how the edibles are made. Dogs not only have an incredible sense of smell, they are also amazing discriminators. When you smell beef stew, the odor you detect is a combination of ingredients blended together. You recognize that combination as beef stew. If your dog is one of the better breeds for detection, such as a Shepard, your dog smells beef, carrots, celery, etc. each individually, and together. Because of that it is difficult to hide the smell of cannabis in other smells.What detection dogs actually smell are terpenes, those compounds that give cannabis it’s unique and often varied fragrance. While you find terpenes in all cannabis, it is not the component that gets you “high”. That is THC, and these days THC can be extracted from cannabis without the terpenes.For use in edibles this is normally the case. Most edibles these days use a standardized extract of THC that comes from supercritical CO2 extraction. This extract typically does not typically include terpenes, as they have to be removed in a separate, sub-critical process that edibles makers don’t use. It yields a standardized THC extract that makes dosing in edibles much easier and more accurate. These edibles won’t alert dogs as they are not actually trained to smell THC (virtually odorless), they are trained to recognize the terpenes found in cannabis.However, if you have edibles that you made by soaking skunk weed in melted butter and using the butter to make your edibles… a police K-9 can nail you.Bottom line - If your edibles are made by a large edibles maker, it is very unlikely there is anything for a K-9 to smell inside. However, if your edibles are home made then I would not bet on getting past a police K-9. Different dogs, of course, have different abilities and the level of training is important as better trained dogs are better at discriminating odors.I spent the better part of a year a about 10 years ago becoming a registered detection dog handler for both explosives and drugs. I have seen dogs that I swear could smell it if you were thinking about smoking a joint, absolutely uncanny. But all dogs are limited to detecting what they are trained to smell and modern commercial edibles typically don’t contain what they are trained to smell.Hope that helps…
How do I determine the sign of a charged object using the electroscope if the electroscope is positively charged initially?
Move the charged object near the top terminal of the electroscope. Do NOT move it so close that it transfers charge.If the object has a positive charge, it will pull electrons up to the top terminal. This will cause the leaves of the electroscope to be more positively charged, causing them to move further apart.If the object has a negative charge, it will repel electrons from the top terminal. This pushes electrons down to the leaves, causing them to be less positively charged, causing them to drop towards each other. If the object has a much larger negative charge than the positive charge on the electroscope, as you move it closer the leaves will drop to touch, then begin to rise again as so many electrons will be repelled from the top plate that there are now more negative charges than positive in the leaves and they will repel again.Observe this as you are moving the charged object towards the top terminal of the positively charged electroscope. If you get close enough for some charge to leak over, things will change, so you want to watch for the first change in position of the leaves of the electroscope.This movement of charge without actually transferring charged particles is called electrostatic induction, not to be confused with electromagnetic induction.http://www.school-for-champions....Rimstardotorg's video illustrating this:
You are given two identical iron bars, A and B. One of them is a magnet. Can you identify the magnet without using any other substances?
Let us see what happens when we bring a bar which is not magnetised (shown in golden colour) closer to one which is magnetised (Shown in gray).In a bar magnet, the intensity of the magnetic field is strongest at the two ends (poles) and weakest at the central region. So the bar which is not magnetised experiences strong force of attraction near the ends of the bar magnet but no force at the centre. See the diagram on the left.However when we bring a bar magnet closer to the bar that is not magnetised, the force of attraction is same everywhere. See the diagram on the right.The facts illustrated above can be used to determine which one of the two is a magnet without using anything other than the the two bars.So you have two similar bars A and B, one of which is magnetised and the other is not. To see which one of the two is magnet, pick up one (say A) and lower one of its ends, first on one of the ends of the other (say B) and then on the middle of B. If you notice that at the end of B, A experience a force but no force in the middle of the B then B is magnetised. If you do not notice any change from the end to the middle of B then A is magnetised.
Why is magnesium (a metal) not attracted to magnets?
Magnesium has no unpaired electrons. To be magnetic, a metal must have at least one unpaired electron (i.e., a spin up electron without a corresponding spin down electron). In general, response to a magnetic field is a property of electron spin.
Do all quartz deposits contain gold?
The answer is "maybe."First things first: gold is found almost everywhere, including dissolved in seawater. If you're in the USA, the geological survey lists locations where significant amounts have been recorded.When it's directly associated with quartz, it often appears in contact zones where the host rock is intermingled with quartz deposits. showing (a) auriferous quartz vein in an E-W trending shear zone at the contact between the granodiorite and an altered mafic intrusive rock. The granodiorite sample studied was sampled from this artisanal pit as shown in (b)-- http://file.scirp.org/Html/4-830...Visible gold in quartz is relatively uncommon: most productive gold mines are either dredge based for alluvial (moved by water) deposits, or cyanide float or mercury extraction of microscopic gold particles, either distributed in soil or hard rock (often quartz bearing) that are too small to see with the naked eye.One possibly profitable mining plan is to metal detector tailing piles left behind by dredging operations: larger nuggets were sacrificed since the smaller gold is much more common.So you've found a vein of quartz.If it looks like this, forget the gold: multicolor quartz crystals like this are probably worth their weight in gold: I value this specimen at $25 a carat. It weighs a few hundred carats…On the other hand, this side looks a little promising around the dark spots in the middle: crushed and processed it might tally $3 or $5 in gold.Assuming you've found a vein of whitish quartz with reddish or blackish inclusions, it's pretty simple, if not easy, to take a small sample: dig up a pound or so, hammer it into powder, then pan the result. Hit up your search engine of choice for panning techniques...If you find a few flakes (mica looks very similar in the pan: two ways to ID it are that it looks much darker in shade than sun, and it tends to cleave into rectangular pieces) then it's time to more sampling. Current mining values are around $10 a ton to be profitable for small scale alluvial operations.Good luck and strong back!
Coyote in my back yard!!!!?
Coyotes don't like people and will only come by, when there is food or small pets. If there is no food in your yard, and your boxer stays in the yard, then coyotes usually won't bother it. Coyotes won't fight with an animal that can hurt the coyote. But if the boxer runs out of the yard where she can get ambushed by a few coyotes, then you're out of luck. ... You didn't hear this from me ... but one thing that you can try is to forget out the pet issue ... instead say that there are small children in the neighborhood, and that you've seen a coyote wandering around in the daytime... And that you are scared that it may have rabies. Animal Control has to respond to all calls for rabies. ... Normally, they can't do much if they can't see the coyote, tho.
Is a public cloud any less secure than a private cloud?
Security can vary significantly among different clouds, but public clouds (especially leading ones) are usually extremely well protected. For example, AWS data centers have multiple layers of physical security, with fences backed by barriers to prevent vehicles from ramming through the perimeter. The equipment is behind several walls with closely surveilled entrances (cameras, metal detectors, etc.), which require badges and personal pins to allow access. Server rooms are even further isolated using electronic control devices; alarms go off if anything is out of order.Aside from physical security, the managed services of public cloud providers also offer data encryption, monitoring and logging, and versatile identity and access control. (Of course, security in the public cloud depends on you as well, and AWS’ shared-responsibility model clearly states that AWS must take care of security of the cloud, while it is up to you to protect the data within it using various tools at your disposal).So it comes down to this: Can your private cloud match this level of security? If you are purchasing a private cloud from a co-located MSP, their offering won’t compare to that of AWS because they are on a completely different level. On the other hand, matching AWS’ security in your own private cloud requires you to invest significantly in securing your physical location, as well as finding solutions for monitoring, logging, and strict access control. If you invest enough time and money, it is certainly doable.Disclosure: AllCloud Is a global Cloud Managed Service provider with over 120 dedicated experts for Cloud infrastructure, platforms and SaaS applications.

Do archeologists carry guns to dig sites to protect themselves from grave robbers?
Not as a matter of course, no.In many places around the world, it’s not legal to carry guns, or there’s an elaborate permitting process one has to go through in order to do so, so in most cases, it’s simply not an option.Where it is an option, it’s still not very common. Many areas are sufficiently law-abiding that armed looters aren’t a meaningful risk. And where they are a risk, an archaeologist is more likely to try to wrangle a police escort or just not go at all.In my experience with such things, archaeologists hardly ever carry guns. If they do, it’s to protect themselves from dangerous animals, not other people.
Would a magnet stick to tungsten?
I just got a golf putter that is supposedly made out of tungsten, and I was wondering if a magnet would stick to it? Or how can I determine it is really made out of tungsten?
