Q:I have fears that effect my everyday life. They would be a fear of hippos (pretty bad) and fear of wrists (extreme) and a fear of tooth picks (bad).The hippos; are cause when I was little I was pushed into a hippo exhibit at the zoo.The wrists: are for stories about cutting and stuff. It's so bad. I cry and hypervenilate and dry heave. It's horrible. And toothpicks: are because they're sharp and pointy. I can't stand them. How can I get rid of these? Seriously, they're taking over!!!
This might have been caused by a spirit or two, but highly doubtful. unless they were on the pics. I'm a sensitive channeler my spirit family can move objects, dial phones, play video games, definitely break things.
Q:I recently got my heater repaired after it was making some unusual noises. That same day, the fire alarm went off 2 times during the day and once during early hours. The next day, the fire alarm went off twice again. My alarm company claimed they had called me each time the alarm went off, but this was not the case. They alerted the fire department the fifth time without my consent, and the fire truck arrived at my house. Luckily, I was not charged but I most definitely do not want this to happen again!It's not smoke, though there is this smell that comes from the heater. What is making the fire alarm go off? There really is no problem with the heater at this point.. is my fire alarm too sensitive? Thanks for your help!
Specsavers do indeed sell swimming goggles, but the availability does depend on your prescription so you are best off going into your local store and getting more information. I also know that the price is slightly different depending on whether your eyes both have the same prescription or whether your eyes are different prescriptions. As for contact lenses it is not advisable to wear any type of lenses in the water with or without goggles. Contact lenses should never be exposed to water that is why they provide special solutions to clean them and the disposables are suspended in sterile solution.
Q:Hydraulic hose joint is spherical and cone sealing, threaded connection, what is the form of joint?
Hydraulic joints are often spherical joints, concave and convex.2 types of teeth with imperial teeth and unf.
Q:I think OSHA would require safety goggles around those things..
Depends on what the old pipes look like inside, if they are not corroded too badly, I would stick with the galvanized. Copper would be my 1 choice but unless you're going to replumb the whole house, there's no real need for the copper. However if you put just enough copper hanging down thru the floor you can convert the rest of the house at a later time without having to disturb your new wall. As an experienced handyman I would not suggest pex for anything in an unaccessible area, it tends to leak, unless you have the kit that actually thermally welds the fittings.
Q:im trying to acces files that was on my old user account but its keeps saying access is denied
Here's a rough guide: Steam: Iron and steel for the frames and superstructure. Wrought iron or steel plate for the frames, and high-grade steel for the boiler. Copper and brass for the pipes, fittings, etc. Diesel, electric: Steel for the frames and bogies, pressed steel or possibly aluminium for the outer body shell, fine grade steel for the mechanisms, copper for the electric wiring Railways revolutionised transport and transformed society, making journeys over long distances much shorter and opening up markets for goods in ways that could never have been possible in the age of horse transport. Locomotives were the engines that powered this transformation. Pollution. Steam locomotives generate smoke and combustion gases, and in the early years of railways many people protested against this. Similarly, a diesel train generates exhaust fumes. However with the advent of road transport many people have realised that trains, forwarding a given number of passengers or load of goods, generate less pollution than road transport. Effect on the landscape. Once the railway had been established, the landscape would never be the same again. Massive earthworks, tunnels and bridges transformed the look of the countryside and towns and cities alike. Coal mines and foundries sprang up everywhere to feed the insatiable appetite of the railways for fuel and materials. That's why it was called, 'The Industrial Revolution'.
Q:How do you explain the pipe joint?
The fittings are expressed in part according to the British system
Q:i want to start selling baby clothes with own designs on (possibly on shop or start own website), and not sure how to go about it? would i be allowed to buy wholesale bulk of plain baby suits or t-shirts, then sew or print my own designs on then sell them on. or would this not be allowed cos clothes would already have someones label in?! or any ideas?? thank you
you need a touch bar, with the right door closer it will shut and lock it when closed, their not really used for residential but they can be fitted to do the job. when you push the bar in the door unlocks, and springs back on its own and locks the door when you let go, it also comes with a allen key to lock the bar in the open position, so you don't lock yourself out. very handy, but can cost a bit. they range from 95 dollars and up. they work dam good so it would be worth keeping this user out of your house, good luck, home depot sells them. make sure you use a good door closer.
Q:And it's not coming from the machine itself, it's adding this noise, it's coming through the speakers. ( speakers are fine with normal TV) but every time I try to record something from the VCR to the DVD, the wine goes with it and gets louder. I've tried multiple tapes, in multiple machines so I'm convinced it's not my tapes. I've also cleaned it with the VCR head cleaner. it still won't quit whining. What should I do? this is only a year old so9 replacing it is not what I want to hear.

Q:A friend of mine gave me a used Mac Pro he found. Everything works fine except it has one of those annoying cable locks clamped on the back. He said he took bolt cutters to the cable to try and shorten it, but the lock part and a few inches of cable remain. I tried pulling on it and twisting it, but nothing works. I can't see a brand name on it, but its a combination type.
The Darcy equation is : Head loss fLV^2/ 2dg For fittings : head loss KV^2/2g If you have no friction , the head loss in pipe is negligible but it also depends on the type of flow , laminar or turbulent, turbulent flow will have more losses ! Then the only loss left out is fittings loss and that will be the major loss in the piping for example losses through valves, nozzles, tees, bends etc.
Q:Every time we turn on the heat, there is a terrible oil smell that comes up from the basement. It gives everyone in the house headaches, irritated throats and eyes. Can anyone explain why and how to resolve this?
They don't mind them in UK. Our fire hydrants are flush with the ground. However, dogs here seem to dislike trees(and my back once when I was sitting on the ground).
