answer:
about twice as much per board foot but you get better quality and longer lasting products,,
question:
Can someone help me think of a catching title?
I need a catching title for my cover page of an paper I am writing for school. This is what the paper says.....
Imagine a world where the sides of roads didn t have garbage on them, or a place where everyone recycled. If everyone did that maybe scientists wouldn t say the world is going to end. Our country is a great place to live, but it would be even better if people recycled and didn t litter. The quote, Ask not what your country can do for you; ask what you can do for you country can do for you, is a famous quote. It asks citizens how they can help our country be a better place to live. If everyone didn t litter we wouldn t have disgusting garbage on the sides of the road. Also maybe more animals will live because they won t be eating garbage that they think is food. If we recycled then we wouldn t be wasting things, and the country would be going green. Everyone should recycle and not litter.
First, people littering is a big problem. When you are driving on a highway the sides of the roads have McDonald s cups, plastic bags, old tires, pieces of cars, paper, boxes, cardboard, and so much more. It is gross look at. The garbage doesn t just appear on the side of the road it is caused by people littering. One day I was in the car with my friend and her parents. We stopped at Sonic to pick up some lunch. We didn t have a garbage can in the car so my friends dad told us to give all the garbage to him. I thought he was going to throw out the garbage when we got back to the house, but instead he threw it out the window. I was in shock. I never thought that he would do that. That showed me that not just crazy people, but normal people like my friends dad litter too. According to, statisticbrain.com, 75% of people attempted littering in the five years. 50% of people dump it into the ocean. Not only does littering look bad, but it kills animals. Animals think that garbage is food when it actually is killing them. Because of litter over one hundred thousand wildlife animals die from littering every year according to, wiki.answers.com. It is sad to see people litter and make the country look dirty. It is also sad to see animals dying because humans are lazy to go throw out there garbage in the garbage can.
Second, we can recycle and help the country become green. Every year more and more cities are helping the country to become greener by recycling. My town just gave out huge recycling bins to everyone in the town so they can recycle. This is one step closer to becoming a better country just by recycling. To make paper we have to cut down trees and it is taking away some animals homes. If everyone starts to recycle paper then the paper will be reduced back into its basic fibers and then used to make more paper. We then just saved a tree and an animal home. If we recycle steal then steel cans and other steel things are re-melted to make things like car bodies or building materials. If we recycle plastic then the plastics are re-melted into little pellets that are re-used to make new plastic containers, artificial wood for decks and other plastic things. By recycling we are saving things the earth needs and taking old things the earth had and re-using it. By doing that we are saving the earth one small step at a time.
As you can now see, recycling and not littering will help our community and country become a better place to live. Just imagine the world where animal death rates weren t increasing because of littering, and scientist weren t saying the world was going to end. We can make a change by not littering and recycling. They are two simple things that your community can do. The quote, Ask not what your country can do for you; ask what you can do for you country can do for you, is a famous quote. It asks citizens how they can help our country be a better place to live. By taking the extra second of you time to throw your garbage in a garbage can and not on the street will help our country look better and may just save an animal s life. If you recycle your garbage we could stop cutting down trees and leaving animals with no home. It will also help to stop waist from piling up and hurting our atmosphere. By doing two simple things the world will become a better and healthier place to live. Scientist may not say the world could end, but might start to say that the world has a good chance of living on longer then they thought. Not littering and recycling is an important thing for the whole country to start doing. We as a country can make this a better place to live by doing just two simple things.
You don't have to read the whole thing if you don't want to but, I put that just so it gives you an idea on what my article is about. Please help me think of a catching title thanks:)

question:
Spilled grease on my frex artificial deck?
I spilled some grease on my artificial deck. I don't know what to use to get the stains out, but hopefully they are not permanent. Should I use hot water, a deck spray????
answer:
You should try hot water - preferably with a pressure washer. I've taken similar stains right off that way on Trex and other composite deck materials. Good luck!
question:
How far do you think technology will go?
Like for instance with google map street view option what do you think they will come up with next actual live footage do you think we will be able to view into places like in the Caribbean and Africa.
What do you think is next with cellphones and the internet.
Do you think one day we will have flying cars and houses that float on water.
answer:
Don't expect flying cars. Not because they are impossible, but
it is just too impractical for all those millions of individuals to be
flying around in all directions at once, like in the film 'The Fifth
Element'. But we won't need them, because what we will have
will be so much better!
Here's a few things to expect (some in the very far future, some
not quite so far off):
Eventually there won't even be a need for cell phones. You will
have a brain implant that allows you to connect to anyone just by
thinking of them. This will be made possible by computer chips
that connect living tissue to computers. Hopefully, having the
chip implanted will be your choice, but it may become mandatory
by the government for 'security' reasons.
This will also allow you to create and experience artificial environments like the 'holo-deck' from Star Trek, just by thinking
about them.
Advances in our understanding of quantum mechanics and the
interconnection of space through higher dimensions, will allow us
to have true transporters that allow instantaneous travel from any
point to any other. This will also allow us to eventually travel between
planets and other stars, making the whole universe accessible without
the need for spaceships.
The internet will be free for everyone, and connect you to everyone
and everything you need for daily life: TV, communication, shopping
and merchants, banks, etc.
There won't be any more cash money. All financial transactions will
be electronic transfers and instant, provided once again by a chip
implanted in your body.
All TV and communication will be 3-D.
Computers will be contained in every device, and every home will
come equipped with a master computer that runs the household by
voice or thought command. Stand alone computers will no longer
exist as we know them, but rather as disposable sheets of paper
that are used once and tossed away. There will no longer be a need
for printed books or newspapers, as all human knowledge will be
accessible via one central giant database. For the same reason,
CDs, DVDs, iPods and most other 'hard' portable data devices will no longer be needed.
There will be a major advance in the area of 'programmable matter',
which will take electronic nano-materials and apply them to a surface.
By applying the correct electrical charge to these materials, you can
change their chemical and physical properties to anything desired.
Applied to the surface of a home, you will be able to flip a switch and
turn a solid wall into a clear window. Or change the color of the house.
Because you will not just be changing the appearance of things, but
their electronic structure, they will take on all the properties of that material: thus you could turn a soft rubber sheet into an impenetrable
solid wall, or a cheap iron block into having all the properties of gold.
In medicine, artificial organs will be "printed" using a large inkjet type
printer device, that will use undifferentiated living cells to print instead
of ink. (this device already exists!)
You will be able to print a new heart valve, or skin, that exactly matches the DNA of the person who needs it.
These are just a few things we could see. And the most amazing part
is that all of these already exist in primitive form and are currently being worked on.
Hopefully, we will be able to avoid destroying ourselves long enough
for these technologies to become fully realized. Unfortunately, military technology is also improving all the time, giving us new and
better ways to kill each other~
question:
Can I have a photo of your green (environmentally-friendly) house?
I'm writing an article for a magazine, and I need a great, not copyrighted photograph of a house decked out with awesome green features, such as bamboo or concrete flooring, recycled glass backsplashes, copper sinks, or other Green building materials.
Anyone know where I can get one?
answer:
Well it's not quite finished yet, but I'm building a full self-reliant home and have lots of in-construction photos you could use if you like.
In a nutshell it:
* Is ultra-efficient with 8.3 house energy rating (HER) stars. This means it uses only 70MJ/m2 of energy to heat and cool per year, which is 37% of the energy used to heat and cool than a 5-star house (192MJ/m2), and only 15% of the energy used to heat and cool an average (2-star) house (493MJ/m2). The maximum in the Australian system is 10-stars, and is defined as never needing artificial heating, cooling, or ventilation. On the South-West coast of Victoria this is 2MJ/m2 which is regarded as being impossible to achieve due to our climate, and 8.5-stars is accepted as the maximum achievable rating for this region.
* Is fitted out with very low energy consumption appliances (solar hot water, low consumption whitegoods, etc)
* Uses rainwater tanks to collect stormwater to supply all or the vast majority of the house s needs
* Has a grey wastewater management system to recycle as much wastewater as possible
* Generates enough electricity through solar photovoltaic panels (and possibly wind) to drive the house's needs for an estimated net benefit of up to ,000 per year over an average house. This is based on zero power bills plus payments from surplus energy grid feed-in tariff.
* Uses only sustainable building materials and practices, such as only using plantation and/or recycled timbers, low toxin glues/paints, etc.
* Has each material/practice s embodied energy as low as possible.
* Is Sited in a productive permaculture principles, to incorporate food production (vegetables, fruit, and eggs), and native wildlife refuges.
Hope that helps
question:
Get more visitors to my site and facebook group?
I've recentley had a pop a building my own site www.justdecking.co.uk and with a lot of effort got it onto page 1 of most of the search engines but yet only getting about 9 visits a day. Is there anyway of speeding up the traffic?
Also does anybody know how to invite people you don't know to my facebook group also called just decking because I reckon this could help with traffic
I know it's technically two questions sorry thanks all for any help
answer:
Yahoo site explorer reports there are 18 links to your site so far, 5 that seemed to be relevant to your biz. The top search result for Decking; trex.com has 7435 backlinks, while you can't expect to ever rank for such a broad term, if one of your articles is on "The most weather resistant decking material" you may rank with the occasional person with that exact interest.
Some SEO pros recommend spending spending 2/3 of your efforts off-site creating backlinks and promoting. Though artificial backlinks are not approved by the search engines, since they are used to gauge a site's popularity, every does backlink building in some form. There are 3rd world crews that an generate 100 backlinks (of questionable quality) for as little as . The monthly lists of dofollow link opportunities published by Angela Edwards show where you can be the 1000th person to place a spam comment or forum signature.
Marketers have pointed out that paid facebook ads are less expensive when the link to a facebook group, it seems that facebook ads have to be more of a soft sell relationship building start.
Have you looked into twitter as another traffic source?
question:
where can I buy new thongs for my ankle-tie sandals?
the thongs (the thin strips of leather) that go round and up the leg on one of my favourite pairs of sandals snapped. Is it possible to buy the material (thin leather thonging I suppose its called) to fix this? My local shoe repairer doesn't have any. Its actually probably artifical leather but real or artificial should be ok.
answer:
Go into any shoe shop and ask for laces for deck shoes. They are, hopefully, what you're looking for, but very probably they'll be brown, you'll have to stain/dye it to match your shoes if they're not brown.
question:
Anyone built an astroturf putting green in their backyard using astroturf and wood (no concrete)? Any tips?
I have a slightly sloped yard so I was thinking about usin the concrete blocks that are used for decks and 4x4 posts to build the supports for a platform so that it will be level. Then make 4x8 frames out of 2x4s and connect these to the posts. Cover with exteror plywood to have basically a pool table. Cut the holes and cover with astrotruf. Any thoughts? I am worried about warping and rot, but unless I want to bring in a lost of fill and/or concrete (which I do not for either) I can't come up with anything better. Thanks.
answer:
Skip the plywood - your fears are correct in that you will have plywood warping in just a few weeks, and wood rot within a few months. The way that the artificial greens are built is using a base of crushed lime (which holds its' shape well after being compacted), covered by astroturf that has a much thicker rubber base than the cheap stuff you can get at your local home improvement store. Once the astroturf is laid, use sod staples (the U-shaped 6" long anchors for holding down sod or landscape fabric) to hold it in place, then top dress with sand and sweep in until it rolls as fast as you want. If you are doing the work yourself, figure around -6/ square foot for all materials, unless you are lucky enough to find a great deal on the turf or the base material. Thus, for a green of 15 x 30 feet, figure ~00-2500, and somewhat more to have it professionally installed.
Before you choke on the price tag, think about this: If you use the right materials and do it right the first time, it should easily last 10 years or longer with very little maintenance (sweeping off leaves, topdressing w/ sand).
question:
How are washing up sponges made?
hey everybody im doing a project at school about how washing up sponges are made but the thing is i can't find any information on the net so can you please help me. I was thinking with a site that has a video which tells you how they make it.
answer:
http://www.madehow.com/Volume-5/Sponge.html
Sponge Background:
There are many different varieties of sea sponges, and these come in widely varying shapes and sizes. They can be very large, and grow in elaborate branched formations, or be round and small, or grow flat or in a tube shape. Some are brilliantly colored, though they fade when they are harvested. Sea sponges are thought to have evolved at least 700 million years ago. They are among the simplest animal organisms, having no specialized organs such as heart and lungs, and no locomotion. Sponges live attached to rocks on the sea bed. Their bodies consist of skeletons made of a soft material called spongin, and a leathery skin broken by pores. The sponge eats by pumping seawater in through its pores. It filters microscopic plants from the water, and expels the excess water through one or more large holes called oscula. It also absorbs oxygen directly from seawater. Sponges are slow-growing, taking several years to reach full size, and some live for hundreds of years.
Sea sponges were used since ancient times in the Mediterranean region where they are most common. Roman soldiers each carried a personal sponge, which served the purpose of modern toilet paper, and they were certainly used for other purposes as well. Artificial sponges were first developed by the Du Pont company a leader in synthetic materials manufacturing industry that also invented nylon in the 1940s. Three DuPont engineers patented the cellulose sponge process, and DuPont held onto the secret until 1952, when it sold its sponge technology to General Mills. In the second half of the twentieth century, cellulose sponges rapidly replaced the natural sponge for most common household uses.
Raw Materials:
Many different types of sponge are harvested and dried for human use, but the most common one is the Spongia officinalis, also known as the glove sponge. Another common type used commercially is the sheep's wool sponge, or Hippospongia canaliculata. Synthetic sponges are made of three basic ingredients: cellulose derived from wood pulp, sodium sulfate, and hemp fiber. Other materials needed are chemical softeners, which break the cellulose down into the proper consistency, bleach, and dye.
Harvesting Sea Sponges:
To gather natural sponges, specially trained divers descend into sponge-growing waters with a large two-pronged hook and a string bag. Traditional sponge divers in Greece used no special breathing equipment. The men of seaside villages were trained from childhood and were expert deep water divers. The sponge industry in the United States centers around Tarpon Springs, Florida, a community that was founded by Greek immigrant divers. Today's sponge divers use modern diving equipment such as wet suits and oxygen tanks. The divers pry sponges off the rocks or reefs where they grow, and bring them up in their string bags. The divers pile the sponges on the deck of their boat and cover them with wet cloths. The animals die on the boat, and their skins rot off. After the skins have decayed, the harvesters wash the sponges and string them on a long, thin rope to dry in the sun. After they have dried completely, the harvesters wash the sponges several more times. This is all the preparation the sponges need to be ready for sale.
Natural sponges are the skeletons of a kind of simple sea animal. They grow in warm, shallow waters, and are particularly plentiful in the eastern Mediterranean and off the western coast of Florida. Artificial sponges have largely replaced natural ones in the United States, where at least 80% of the sponges in use are manmade.
Synthetic Sponge Manufacturing Process
1) The cellulose used for sponges arrives at the sponge factory in large, stiff sheets. Workers take the sheets and soak them in a vat of water mixed with certain chemical softeners. The cellulose becomes soft and jelly-like. Then workers load the cellulose into a revolving mixer, which is a large rotating metal drum. Workers add the sodium sulfate crystals, cut hemp fibers, and dye, and close the mixer. The mixer is set to rotate, and it churns the ingredients so that they are thoroughly amalgamated.
2) From the mixer, workers pour the material into a large rectangular mold that may be two foot (61 cm) high, two foot (61 cm) wide, and six foot (1.8 m) long. The mold is heated, and the cellulose mixture cooks. As it cooks, the sodium sulfate crystals melt, and drain away through openings in the bottom of the mold. It is their melting that leaves the characteristic pores in the finished sponge. The size of the pores is determined by the size of the sodium sulfate crystals. A rough sponge used for washing a car, for instance, is made with coarse crystals, while a fine sponge of the type used for applying makeup is made with very fine crystals. As the cellulose mix cooks, then cools, it becomes a hard, porous block.
3) The sponge block is then soaked in a vat of bleach. This removes dirt and impurities, and also brightens the color. Next the sponge is cleaned in water. Additional washings alter the texture, making the sponge more pliable. The sponge is left to dry, to prepare it for cutting.
4) Some manufacturers make the sponge and cut and package it themselves. Others produce the raw blocks of sponge, and then sell them to a company known as a converter. The converter cuts the sponges according to its customers needs, and takes care of the packaging and distribution. Whether at the first manufacturing facility or at the converter, workers cut the sponges on an automatic cutter. They load each big rectangle of sponge into a machine that slices it into the desired size. Because the sponge block is rectangular, it can be cut into many smaller rectangles with little or no waste.
5) Many household sponges have a textured plastic scouring pad attached to one side. This is attached in a process called laminating, after the sponge is cut. The scouring pad, which is cut to the same size as the sponge, is affixed to the sponge in a laminating machine that uses a specialized sponge glue made of moisture-cured polyurethane. Next, the sponges move to a packaging area where they are sealed in plastic. The packaged sponges are boxed, and the boxes sent to a warehouse for further distribution.
Details of the Process:
Softened cellulose is mixed with sodium sulfate crystals, cut hemp fibers, and dye in a large, revolving metal drum. Once blended, the material is poured into a large rectangular mold, which may be 2 ft (61 cm) high, 2 ft (61 cm) wide, and 6 h (182.9 cm) long. As the mold cooks, the sodium sulfate crystals melt, and drain away through openings in the bottom of the mold. It is their melting that leaves the characteristic pores in the finished sponge.
Quality Control
A sponge manufacturer typically checks the product for quality at many steps along the manufacturing process. The raw ingredients are analyzed when they come into the plant to make sure they conform to standards. In a modern facility, most of the machinery is monitored by computers, that maintain the proper proportions in the mix, for example, and control the temperature of the mold during the cooking process. The finished sponges are checked for tenacity, that is, how easily they tear. An inspector takes a random sample from the batch and puts it in a specially built machine. The machine measures the force needed to tear the sponge. Another test is of color. In this case, a sample sponge is examined under a spectrograph.
Byproducts/Waste
Sponge manufacturing produces no harmful byproducts and little waste. Sponge material that is lost in trimming, such as when an uneven end is cut off the large block, is ground up and recycled. It can be thrown in the mixer at the beginning of the process, and become part of a new sponge.

question:
We have our kitchen counter made of GRANITE, is it safe in terms of rock radiation? How can we test it?
answer:
As with most all 'dangers' in our homes this one is proving to not pan out. Most all of these rumors have been started by competing makers of other products. You cannot say that there is no risk in anything. Take for instance the rumors about in home electrical wires being harmful. How about the rumors of carpet, sheathing, deck arsenic, paints, microwave emissions, plastic wraps used in microwaves, hardening materials for plastic water bottles, dryer sheets, laundry detergent, alar with fruits, artificial sweeteners, cold remedys.... Some of these had a point worth considering, but most of the time to have harm you would have to be literally immersed in the product. A well ventilated, dry, filtered home is the safest bet.
question:
Composite decking for bird house?
Would it be OK to make a bird house out of composite decking? Or would this artificial material turn a bird off from nesting in it?
answer:
Some composites have been known to carry chemicals which probably is not very healthy for a place to live in. I know it just a bird. Clear western red cedar is the best choice here.
question:
Does this spacecraft design seem plausible (for science fiction based in realism)?
It is supposed to be a ship that transports large groups of people (Crew and passengers) to and from Mars. It is about 150m long with a central collumn 4 metres thick and cylindrical. One important thing to note is that the entire ship rotates at 6 RPM except in emergencies.
On one end is a docking bay for ships, which is a larger cylinder about 23m in diameter and capable with a mostly rectangular hole about 22m by 13m and 30m deep. The shuttle/landing and launch ship will enter here with passengers, fuel and cargo and leave at arrival. The craft itself docks in orbit and does not land. Above and below the bay, in the cylinder, there are 4 main thruster engines. The ship has no reverse engines, instead, it has 4 small thrusters on the side of the cylinder 90 degrees apart to turn the ship around to reverse acceleration. The docking bay main section is capable of rotating within the cylinder to allow ships to enter quickly and easily and then gradually return to the 6rpm rotation of the rest of the ship.
Just after the docking bay cylinder is the main section of the ship which is made up primarily of two doughnut centrifuges, each 17m radius, providing approximately 0.7g simulation, somewhere between Earth and Mars. Each of these is not curved like a doughnut but flat on the floor (Not sure how to explain, but like the space between a biscuit tin and a smaller tin inside it rather than curved around the edges like a doughnut). Anyway, obviously the people stand on the otuer edges and it's about 4.5 metres tall, some of which is storage space, not walking space. The centrifuges are attatched by 4 collumns to the central collumn and also to each other by a tube on the outer edges where artificial gravity is still in effect. The spin is powered by angular thrusters and for most of the journey, inertia, since there is no friction as the whole ship moves). Ballast tanks will keep the ship balanced.
One of these centrifuges is 4m wide and the other is 6. I haven't decided on specific purposes for each but I think they'll just be different habitat zones, maybe one is higher class. The ship will only accelerate during sleeping hours (After it's initial main acceleration), and the beds are designed to rotate so as to account for changes in the direction of force and keep gravity feeling like it's down. At these times, gravity will be closer to 1g to allow for a good Earth sleep.
Between the centrifuges around the centre collumn is the primary storage area for cargo and the secondary one for fuel. It is a cylinder 14m in diameter and 10m long. There is a secondary storage cylinder of the same diameter and 6.5m long.
Then there is a long neck with nothing but additional bays for modules that might be needed for various missions and at the end there is an observation/navigation deck. It has a large glass window (can be covered up) for viewing and like the docking bay is capable of counterrotating against the rest of the ship when needed, and also can eject from the main ship in emergencies.
A few more details. There are 3 rings each with 4 equidistant solar panels on the neck on the observation deck side of the ship (these stick out beyond the width of the centrifuges) and one between the centrifuge and the docking bay. There is also a twin sattelite dish ring, and these stick out even further. All these are capable of couterrotating if necessary. Each centrifuge contains 4 escape pods and the primary storage cylinder contains 4 EVA pods.
Another thing I'm considering is having the rotation speed change as the journey goes on to become closer to the destination planet.
Anyway, what are your scientific thoughts? I have no scientific background, just been looking up spaceship design, so I could have made many mistakes. Any suggestions on how to improve it?
http://fc08.deviantart.net/fs71/i/2013/012/1/1/very_basic_interplanetary_vessel_design_by_spectic-d5rc0v3.png
Thanks, G. I will probably scrap the acceleration while sleeping idea, I really only did it because I thought it would be good because the beds could be designed to move independent of the main floor, which would be changing it's "down and up" when accelerating".
As for the changing the speed of the spin, would that really take much fuel? I would have thought this alone would be pretty minimal in a vacuum, compared to things like linear de/acceleration, since that will need to be thousands of times more significant because of how fast it would have to travel. Still, keeping the RPM low, if it wouldn't be too problematic for the astronauts would probably be good and minimise the coriolis effect.
Maybe it should be closer to Mars gravity when going to Mars and closer to Earth gravity when returning to Earth?
answer:
any design that works is fine but let me go through some of the minor things I have seen.
first COST is the most important thing for a mission ... LIGHT mass spacecrafts are a must.. plus they must be made to keep high energy projectiles out ..
also the light mass is required to keep accelleration and decelleration costs down.
and this means LESS FUEL
you plan to accelerate when people are sleeping.. assuming they all sleep at the same time probably an inefficient idea to have in small are..
for example submarines have only enough beds FOR HALF THE CREW.. this means half the crew sleeps while half the crew is awake .. that limits unneeded empty space
all space is then used to the fullest..
also accelerating during sleep periods of a trip that will take somewhere from 3 to 6 months means you will have to DECELERATE that same amount making for ALOT OF FUEL costs...
not likely .. space travel is different then terestrial travel in space once the space craft starts moving it sstays moving so the spaceship should keep a steady speed the whole trip and not accelerate..
sleeping in space is comfortable as with 0 g's there is no position that is NOT COMFORTABLE..
this means most astronauts just clip their sleeping bag in the position they like.. sideways upside down whatever as there is NO UP OR DOWN... OR left or right it just where you put yourself you will stay..
so there is NO NEED OR desire for acceleration during sleep ..
this will save MANY THOUSANDS OF GALLONS OF FUEL..
the ship should be made of light materials there is a design for a ship made of INFLATABLE METAL fabric ... it has many chambers throughout it and after it is inflated in orbit at earth it holds the shape it was designed for ..
it has many advantages .. first on micrometeor strikes the pockets in the metal fabric slow down and divert the meteor thus a meteor that would penetrate a 1 inch solid steel plate would not penetrate this lighter fabric inflation system..
also something like this could be patched easily with a simple patch kit and no special welding material
===========
the rotating centrifuges are good idea if the persons need some type of gravity but I think getting a gravity of 0.7 g is probably over kill but will probably be doable ...
changing rotation speed of the centrifuges or changing acceleration is never a good idea conservation is the name of the game...
what its set at on earth should be the value it is going to be on mars ..that way the person will get used to mars level over the 3 to 6 month trip there..
question:
Can anyone suggest sustainable and affordable material(s)?
I am a student-designer who is presently working on a series of tables. What I am looking for is a material that can be cut easily and is sustainable/environmentally friendly, durable, and affordable. I live in New York City and therefore would prefer it to be accesible either directly (I'd be glad to pick it up!) or through (quick!) delivery. Also, though I am open to anything from plastics, resins, bamboo, compressed paper, etc., I need something that can come in "sheet/ply" form (as in a tabletop.)
I'm open to everything, I just want it to be as affordable as possible and to look really nice. I do realize I haven't been too specific -- I feel as though that will allow for the most potentially hopeful answers. THANK YOU!
answer:
There is a recycled decking material made from compressed saw dust and resins. It's brown like cardboard...and Its looks are those of an...oh... artificial decking material. It's waterproof and very durable. It is not load bearing however (it could only be your table top, or a bench seat or the like.) Basically these would be eco-friendly planks of wood. I don't know what they call it, but it's been turning up more and more. Any lumber yard/mega hardware store would have it. I know I've seen Home Depot in Manhattan.
question:
Is Pete Wentze still with Fall Out Boy?
Cause I just say a recent music video (What a catch donnie) and I didnt see him any where
answer:
ow that the deck frame and joists are in place and ready to support the weight of everything that you put on your deck, you can install the decking, or floor, of your deck. You have a variety of materials to choose from - pressure-treated wood, redwood, cedar or even artificial wood. Your choice will be based on your preference for aesthetics versus ease of maintenance.
question:
artificial gravity through mass?
okay to have gravity you need mass and huge weight. so if a spacecraft has the ground and the floor made out of real heavy metal or something else that is huge on mass and huge on weight than wouldn't you basically have gravity inside the spacecraft.
answer:
You would need an insanely dense material in order to do this, think neutron star material. There are a number of problems doing this, one is that this would make your ship so massive that it would make accelerating, braking, and maneuvering near impossible, another would be there would not be enough distance between the superdense plates, the one on the deck above you would be pulling on you just as much as the one you are standing on
question:
what is the best skateboard brand?
yes i am a girl so i want to buy a skateboard and i wanted to know what is the best company to buy a skateboard from that has good wheels that don't break good trucks and i want a strong board that wont break for a long time please help me
answer:
Your best option if money isnt limited would be to make a custom deck from your local Zumiez. I bought one about two years back that cost me about 130$ for very nice trucks wheels bearings and my deck of choice. Most decks are made of similar materiel (wood, but some are made of composites, aluminum, nylon, Plexiglas, fiberglass, foam, and other artificial material) though I recommend buying a decent brand because their decks usually arn't crudely made. As for bearings bones reds are pretty good and all of my friends recommend them. Wheels are usually chosen based on looks but they can be chosen based on Diameter and Durometer. Diameter is how tall they are and msot skaters usually choose somewhere around 52mm-54mm. Durometer is how hard they are. Most skaters choose a durometer around 99a. Trucks usually depend on style but I use Tensor.
I happen to love the Enjoi decks and even after a couple of bad tricks have never broken my board.
I hope that I got all that!
question:
Does God interfere in human affairs?
Lactantius always spoke ill of Lucretius due his idea of a peaceful and undisturbed God that wouldn t interfere with the world -for he foresaw in this the end of religion- but it is true a God deprived of its own perfection would be no God at all. It would be inconsistent with God s nature to suffer from the very same affections that pull the strings of nerves and blood every human being is made of. No father would chose sides when his sons fight each other for petty things. If it were possible to drag God to our side he d be deprived of his own will. Lactantius understood vengefulness as opposed to mercy and thought a merciless God a God deprived of forgiveness for if God were deficient in one thing he would necessarily lack the other. What Lactantius does not see is that a God deprived of his perfection would be no pattern to follow and, therefore, this would be the same as basking in perpetual darkness. If God followed this path he would make his offspring orphan, there can be no doubt. It is not to God to turn human but to men to become like Gods.
answer:
Good going-- you answered your own question brilliantly, George.
It is easy to see, in the gross workings of history, that even the mass of people can't dispute, that God has not "interfered" excessively-- or, more correctly, has not intervened very much (since God, presumably an authority and creator, cannot "interfere" in His or Her own business!) He, She, or It has done neither, has typically done nothing whatever to help when millions of free African citizens were chained into slave ships, other millions of Jews in Europe exterminated. God did not "interfere" when a group of five-year-olds in Mexico, decked in their caps and gowns for kindergarten graduation, were blown away in a hurricane.
The history of God's gross and conspicuous non-intervention is too long to list in a thousand volumes. You gave us a good line: "..it is not to God to turn human but to men to become like Gods." Sounds like good old "Fred N." (I never could spell "Neitszche" with any self-assurance. Too many consonants.)
People becoming either godlike or godly hasn't happened, and I see no prospect that it will, but it is a good thought that we can ponder in those idle times when we aren't thinking and acting like some nutty breed of malicious monkeys. Collectively we are a potentially deadly ecological epidemic that is likely to be cured only in the process of killing off all life in the world hosting us. Insofar as our potential for becoming Gods, we are developmentally flawed. The angels, long ago probably spotting us as spiritual and moral retards, no doubt weep in frustration, unable to deny the apparent folly of a Creator who they, as His servants, are supposed to hail as all-loving and all-wise.
Mankind is good at making up gods, and perhaps, with the creation of robotics and artificial intelligence, scientists will someday learn how to create artificial love, wisdom, and omnipotence. If so, how will "G.O.D." (the Grand Ordering Device) judge Its creators?
(I happen to hope that there is a God who, in eternity, makes up for his laissez faire attitude in time. Contronted with evil and injustice, we continue to be reassured that God has His purposes, and, being an old man and ill, I grasp continually at these feeble straws of hope.)
As my temporal life wanes and eternity approaches, I shall be "dying with curiosity" as to how He, She or It is going to explain Him-, Her-, or Itself. Will God somehow come up with a good answer, squirming out of the widespread indictment for divine negligence, or merely snort flames and send all questioners and doubters to Hell?
Everybody has heard of the atheist who had his infant daughter christened-- "Just in case," he said. Before the material was banned eternally by the U.S. government, I understand that there was a company that manufactured asbestos burial gear that skeptics and doubters could be buried in-- just in case!
question:
best wood for front porch?
I have a large front porch which is rotted and needs to be replaced. The porch now is painted which is peeling off. Someone told me to use stain with color instead of paint. Since I have now decided to replace the wood and then paint as opposed to just painting it, I need to know which wood would be the best. I was going to have cedar but now I heard that you don't want to paint that for a couple reasons, one being the expense of cedar. Can anyone tell me the best wood to use for the decking of the porch, and also how it should be painted? Thanks.
answer:
If you are going to prime, paint and maintain the porch, regular white pine is OK. Cedar is best, but does not need to be painted, however it will look nice with a good stain and oil finish.
Other materials to consider are pressure-treated, TREX type artificial wood, and aluminum. All have plusses and minuses, mostly to do with expense.
question:
What happens to the stuff you recycle?
like tin cans etc.
answer:
Glass is re-melted and molded to make other glass products or it is crushed and used as gravel to build roads.
Paper is reduced to its basic fibers and used to make new paper.
Steel cans and other steel things are remelted to make things like car bodies or building materials.
Most aluminum cans are melted down to make more aluminum cans.
Most plastics are remelted into little pellets that are re-used to make new plastic containers, artificial wood for decks and other plastic things.
question:
artificial grass in the dog run?
I am planning on creating a fence to make our side yard (about 7X25) into a dog run. We have very clay like soil, and some walkway, plants on it right now and with no sun all day long. (we live in southern CA).
There is some suggestion on having rocks/compose to lay the ground. But i was reading it online on artificial grass, that will be able to drain thru (so i can wash it by flushing the urine out, but assuming have to pick up the poop still)
Anyone done this or know if it's a good idea? My 2 dogs, (12lb maltese and 30 lbs cocker spanial mix) will be there max. of 6 hours a day (on the days i work) with the door to the garage open as well for their use.
Anyone know approximately how much it will cost? and if there is a specific brand (does the brand even make any difference?)
Thank you!
answer:
I actually used it on my deck, so I could close off the small entrance and give my pup a (small) place to safely play. I would pick up the poop, and rinse off the urine every couple of days with a couple of pots of hot water, like you said. It worked great!
I forget how much I paid... my boyfriend actually took the measurements and went to the hardware store, but I`m sure any good (sturdy) material would work just fine. I would give your local hardware or building supply store a call and ask for an estimate based on your measurements, I`m sure they`d be happy to tell you over the phone. Good luck :D
question:
Deck is too hot to walk on?
My landlord finally had our deck redone because it was leaking into our first floor... However it is not what I expected. They basically just placed some black plastic material down and called it a day. I was expecting some wooden planks or something but that's not what I got... Now the deck is WAY too hot for me or my dog to go out on. It burns my bare feet and makes it unbearable to just stand out there because the air is so hot out there. Is there anything I can lay overtop of this material to help keep it cooler out there. Thank you!
answer:
You could try some indoor/outdoor carpet. Perhaps artificial grass carpet. If you want to spend a little money try a teak matt. There are teak bath mats you can get at lowes and similar. You might need several of them to cover and that would be expensive, but it might look nice. Try a woven mat of some sort like sisal rug. Any throw rug that can stand up to the weather would do, I think.
question:
what would be your design for a reusable interplanetary spaceship?
Assume you have been granted a contract to design a reusable interplanetary spaceship. This will be "The Ship". Has to be reusable. Must last min 100yrs. Scalable(modular). Easy to retrofit to be develop powerplants and other technologies Must have a cargo hold (bay) to store payload, lander/ROV vehicles. At least two high power chem lasers to destroy any possible debris, asteroids, etc. that might compromise the ship. Bridge or cockpit, science lab, crew quarters, exercises, lavatories, galley. Most accommodate a crew of 12. Some sort of artificial gravity section will be nice.
Do you have the technology for this?
How would you build it?
What would you use to built it?
What is your proposed layout?
What would you use for propulsion?
What would be its estimated size?
Shape?
How much do you think it would cost?
Ideas please!
answer:
That's an interesting question!
Assuming there are no budget and or time constrains the possibilities are endless.
Sort of agree with the poster before me that by the time the construction is over it will be obsolete. But you have an interesting spec to be scalable and modular.
Your specification for 12 occupants, cargo bay or launch pad, artificial gravity and chemical lasers like the ones in use in the 747 dictates that the ship has to be large.
The first idea resembles something in the lines of 2001 Space Odyssey Discovery spaceship (without HAL). Bridge up front, launch bay one deck below, a spinning ring behind, communications, fuel and engine in the back. Like the movie Mission to Mars, the Discovery type design share the same weak point. Exposed fuel cells.
My design would be different in which the spacecraft will resemble more to a submarine. The hull should be constructed of high density/inertia impact resistant material, this will also reduce radiation exposure. Like sections of a solid rocket booster, modules will mate to form the spacecraft. That will allow for future retrofits. Again, bridge in front, living quarters behind an artificial gravity ring behind that, followed by electronics, communication, defense systems, lasers, fuel cells and power systems.
Propulsion will be a hybrid of all we use today. The main engines will be liquid ox hyd same for maneuvering thrusters. Maybe integrate some version of electric propulsion like ION engine. Power could be a mix of nuclear and solar.
The ship would be constructed in orbit inside a giant inflatable balloon type hangar. This will help contain the ship and minimize the risk of parts/tools flying away in case of a mistake. Similar to how airplanes are service out on the ramp during winter.
I think the technology is already available just never executed to this scale. Political will is the issue in these kind of projects.
Construction would be similar to the ISS, modular.
Depending on the structure, there are many type of alloys used. Aluminum, chrome-alloy, titanium, steel and many more.
The cost would be in the billions! if not trillions!
Don't think the economy and political environment at the moment is concussive for these kind of projects but it would be nice to have one in the future.
question:
Anyone else with a bad ankle that repeatedly sprains?
Way back when when I was an eight year old kid I badly injured my ankle. We were out on my family's sailboat and my dad was working on the boat engine - which is under the stairs. Being a kid I was goofing around on the deck and went to run down stairs. Since the stairs were moved aside I fell down into the cabin and my father's toolbox fell on my ankle - badly spraining it .
Years and years have gone by and every few months I step on an uneven surface and my ankle gives way. It's always an "inversion" sprain - with my ankle turning in. Sometimes it's just a temporary discomfort while other times I'm hobbling around for a week or more. Normally I can run, I can hike, I'm in decent shape. If I wear my hiking boots I'm fine - it provides the support to prevent this - it's usually in other shoes that this happens but I obviously can't always wear hikers. I've sprained it when I was running across a grassy area with the dog and found a small hole, tripped off curbs. I guess my gracefulness could use work LOL
Today I was out back about to do some yard work (NOT in my hiking boots which I always freaking wear out there, damn it!) and went to walk down the steps from the upper part of my back yard (I'm on a hill) and slipped on some pebbles and
My question to any of you that may have dealt with something similar:
Years ago a doctor suggested reconstructive surgery on my ankle - putting in I guess something artificial to make up for the wimpy or beyond repair ligaments in my ankle. Have any of you had this sort of operation done - or know someone that has - and has it worked for you/that person? I'm not worried about cost as insurance would cover most of it.
I'm tired of falling and right now I'm, once again, hobbling around with an ankle brace on and a VERY painfully sprained ankle and quite bummed that I won't be going hiking this weekend :(
Wow - lots of you with the same thing going! Love the story about the cadaver parts - hey, he or she didn't need them any more LOL!
Pixie - you can come visit me in WA anytime. Just bring sturdy hiking boots or we'll BOTH be on our asses somewhere in the woods. I did trip off a trail once even in my boots and landed in this nasty mucky pond. I had to hike about 2 miles back to the trailhead looking like a mudbeast from hell AND limping LOL
I bought this nice Neoprene brace at Walgreens and have worn it the last few days. Definitely helps. I really wrenched it bad this time - the entire outside of my ankle is red and purple bruised. I also have more of a "cankle" than ankle on my left side at the moment :-/
answer:
I can totally understand your story!
I had the surgery you're doctor was talking about in 1998. Mine was so bad they took out my damaged ligaments and replaced them with cadaver ligaments (yes, dead body parts!).
It was a good thing I had the surgery when I did, turns out from the repeated sprains and strains and weakened ligaments, the bones in my ankle were taking a beating. Several were worn thin and in danger of breaking with the next sprain. So they also performed a scope and cleaned out a lot of ratty material from the repeated injuries.
11 years later the ankle is still stable. Infact, I'll break it before I sprain it it's so stable.
I have a fantastic orthopaedic surgeon, I'm very blessed. In 1998 I was still active in EMS and the repeated injuries were really holding me back. 8 weeks after surgery I was back to full duty.
Go on with the surgery, you'll be much happier for it.
question:
what makes brige structurews strong>?
hy
thankyou
answer:
Depends on what type of bridge you're talking about: beam, arch, suspension, or cantilever.
(1) The beam (sometimes called truss, as below). The "original bridge" basically just something that someone laid across a river or whatever type of something it was that he wanted to cross. When children lay an old log over a tiny forest gully, they've created a beam bridge. As a general rule, these simple bridges are also the weakest bridges. The longer the beam, the weaker it gets. A beam bridge needs to be stiff. It needs to resist twisting and bending under load. In its most basic form more than a guy throwing a log, a beam bridge consists of a horizontal beam that is supported at each end by piers. The weight of the beam pushes straight down on the piers. Under load, the beam's top surface is pushed down or compressed while the bottom edge is stretched or placed under tension. So the "neutral axis" through the beam will bow down. The top wants to crunch together, and the bottom wants to split open. Even with modern materials and technology, a single span will almost never go longer than 250 feet. However, simple beam bridges can be joined together to span as long a distance as you want - this is a "continuous span" bridge. In the end, the stiffer the material and the stronger the piers, the stronger the bridge structure will be. A truss bridge is basically a fancy beam bridge. The truss is a triangular design used for support to hold up more weight and span more distance. The triangular supports span across the top sides of the bridge, and sometimes trusses are part of the under structure of a truss bridge. The Garden Bridge, Shanghai, is a good example of a truss bridge (famous pure beam bridges don't really exist).
(2) The arch bridge was the first really technologically advanced engineering for a bridge. We've all seen it - the base arcs upward from the base of the two ends, meeting in the middle at the highest point. In this type of bridge, the weight is carried outward along those two curving paths. The points where the arch reaches the ground keep the bridge up by resisting the outward thrust. This makes arches very useful if you have solid rock or an artificial, and very heavy base structure (abutments) - if the base of yor your arch can push out the anchors, the bridge will fail, which will suck for anyone trying to drive across it at the time. Like beam structures, they can also be made of steel, though due to the high compressive strength of quality concrete, that material is also used, especially down here in Southern California. In a manner similar to the beam bridge, you can connect many arch spans together to form what is called a viaduct. The New River Gorge Bridge
in West Virginia is a beautiful example, which until very recently was the longest single-arch bridge in the world.
(3) Suspension/Cable-stayed bridges, in their basic form, the deck have a deck which is hung by cables which hang from towers. The cables transfer the weight to the towers, which transfer the weight to the ground at vertical caisson foundations beneath the towers and massive anchoring abutments at either side of the bridge. Cable-stayed bridges have towers, but cables from the towers go directly to the road deck, instead of spanning from tower to tower. Suspension bridges can span extremely large distances, and are also extremely stable and strong - any ground motion, such as earthquakes, is turned into relatively isolated swinging motion of the deck, while the vertical and horizontal loads are well locked between towers, caissons and abutments (this is why the Golden Gate Bridge is such a magnificent structure for the area and job, having *never* suffered *any* form of damage from an earthquake - compare to the boxed Bay Bridge which is always falling apart). Unfortunately, these types of bridges are very expensive compared to other structures, and are only used when absolutely necessary - such as the Golden Gate, which needs to be very tall, and very long, so as to span the entrance to San Francisco Bay but without getting in the way of naval or maritime traffic. The Brooklyn Bridge is another fine example, built for similar reasons. Incidentally, in all of the disaster movies where the Golden Gate Bridge *does* fall down, I have never seen anyone get it right. The bridge always falls forward to the center. In reality, the cables are constantly under tension pulling them *backwards.* This tension is what helps to keep the road level. So if a disaster happened that really did split the bridge, one end would fall back on San Francisco, and the other would fall north onto the Marin Headlands.
(3) In the cantilever type of bridge, two beams support another beam, which is where the deck is. The two beams must be anchored, and this must be done well. Cantilever bridges depend on counterbalances, which are weights used to balance another weight (hence the clever name). They cons
