And she's stupid and wares daggy clothesAnd the president is only a face, but has no personslity and has nothing important or interesting to say! And why does America stick it's nose where it doesn't belong?? Look at all the countries it's invadedThere are obese people there that have to be lifted by cranes, it's weird! And even the tv shows are weird! Like days of our lives, bold and beautifulIf you don't watch them for months then start watching again, the story still hasn't changed, ridge is still running from Brooke to Taylor!! It's stupid! And the celebrities are so fake! Fake boobs, fake teeth, all the cosmetic surgery, the ugly clothes and make up, their eating disordersSuch a weird country!!!! Why ??

Would expect the feminists to let a good recession go to waste? I don't know why anybody is surprised, the feminist response to a recession was always going to be to try and use it as an excuse to transfer employment and largess from men to womenThis is exactly what I would have expected from themSort of like how governments are using the recession as an excuse to expand their activities and influence hugelyThe feminists were always going to want those jobs to go to women rather than the men who previously held them, why would anyone expect different?
Q: I have been using a CPAP machine successfully now for about five weeks, and I feel so much better ! There is a problem I need help with thoughThere is a lot of soreness across the bridge of my nose where the mask restsI am talking about the bridge that is close to my eyesAny suggestions out there ??
try putting a breathe right strip(used for snoring) either on your nose or on the part of the mask that rests on your nose as a cushion to the area
Q: How do they built bridges in the ocean? When the sea floor is sand and the current is so strong?
The ocean is too deepThe Golden Gate Bridge has a single span, with supports built on land at either end, with no support in the middle because the water is just too deepThe old San Francisco-Oakland bridge has a lot of spans, with support in the middle of the Bay because the SF Bay is relatively shallowNevertheless, when it was built, wooden support was used in the eastern spans, and they would not withstand a big earthquake, so a new bridge was builtGenerally, the top part of the sea floor is made of loose sediments, but the deeper parts are more solid because the weight of the water and the sediment above compress the lower layers This more solid, denser layer can provide support for a bridgeThe support comes in the form of concrete pillars that are driven into the sea floor using pile driving machinesThese concrete pillars can support the weight of the bridge and the traffic above better than the wooden ones that were used to build the eastern spans of the San Francisco-Oakland Bay BridgeHigh rise buildings on land often use the same technique, as you may have seen or heard the sound of the pile driving machines at construction sites on landRecently there is a news story that the noises these underwater pile driving machines may bother the whales, which communicate with sound, and they also have sensitive hearing that can be damaged by loud soundsSomeone invented a device that can muffle these sounds to safe levels.

Q: In an industrial incineration plant (waste-to-energy facility) trucks unload household garbage into a garbage pitThen a crane grabs few tons at once and lifts it to drop it into a boilerAs new trucks arrive new garbage is dumped into the top of the pitSo, how does the garbage at the bottom of the pit ever gets a change to be lifted and burned?
Aluminium foil is useless as an insulator since it is a good conductior of heatHowever It could be used as an outer cover of the device to keep the peper dry when the device is placed in then snowIt is important to keep the peper and the cotton dry throughout all the experimentMoreover the aluminium will reflect the exterior heat and coldIf the outer cover is paper , be sure not to get it wet as this will destroy its insulative qualities.
Q: quot;Warehousing and MHE experience is desirable but not essential.quot; I have googled it, and it's come up with quot;material handling equipment (or engineering)quot; Whilst I have no idea what it is, I need to know purely because I need to right something that would make me appear suitable for the position.
MATERIALS HANDLING EQUIPMENT 1Transport EquipmentEquipment used to move material from one location to another (e.g., between workplaces, between a loading dock and a storage area, etc.)The major subcategories of transport equipment are conveyors, cranes, and industrial trucksMaterial can also be transported manually using no equipment 2Positioning EquipmentEquipment used to handle material at a single location so that it is in the correct position for subsequent handling, machining, transport, or storageUnlike transport equipment, positioning equipment is usually used for handling at a single workplaceMaterial can also be positioned manually using no equipment 3Unit Load Formation EquipmentEquipment used to restrict materials so that they maintain their integrity when handled a single load during transport and for storageIf materials are self-restraining (e.g., a single part or interlocking parts), then they can be formed into a unit load with no equipment 4Storage EquipmentEquipment used for holding or buffering materials over a period of timeSome storage equipment may include the transport of materials (e.g., the S/R machines of an AS/RS, or storage carousels)If materials are block stacked directly on the floor, then no storage equipment is required 5Identification and Control EquipmentEquipment used to collect and communicate the information that is used to coordinate the flow of materials within a facility and between a facility and its suppliers and customersThe identification of materials and associated control can be performed manually with no specialized equipment.
Q: If you have a large home over 20,000 square feet, what is protocol to give tours to friends, etcI already had a open house, but there are stragglers and out of town relatives, etcI am getting exhausted on giving these tours which can take up to an hour or more at timesAlso when kids are involved, they love to ride the elevator, and to me it is to be used as a necessity rather than as a toyJust wonder how you would handle this ?
If this is a frequent enough occurrence to be an ongoing problem, can you furnish the doors of the elevator with a combination, so kids can't mess with it? If that's not possible, inform the parents that the elevators are strictly off limits to their children unless they're with an adultFolks we know who show people through their homes don't usually have them look at every last bedroom or bathDoors which are closed generally remain closed, and if someone asks what was there, they're told, Oh, it's a private roomTry to keep people moving along, and wait to discuss your interesting furnishings until you're all back in the main living areaOne big drawback about giving house tours is that some people consider them carte blanche to wander around afterward, anywhere in the houseIf this has become a problem, maybe you should only show them places like the living room, dining room, family room, library, and kitchenYou're not a real estate agent or a docent in a paid tourist attraction, after all!
