Paving - Indian Sandstone patio - jointingI have no idea what silver sand is. I would be tempted to pry out a chunk of mortar from the existing mortar and go to a specialty tile shop. "Hi, can you match this?"That said, matching mortar colours is a crap shoot. You may find that to get a match, you will need to scrape out 1/8" of the existing mortar everywhere, and redo it.2.

Granite & Sandstone. ....I need help.?Granite is an igneous rock. It would have to erode and be carried away by water to form sedimentary deposits. Upon burial these sediments could consolidate into sandstone rock5. building a sandstone rock wall?Lucky you! People pay good money to buy stone and have it delivered. First thing you want to do is to sort out the pieces for approximate size, this will help you find the size and shape of the rocks you select as you build the wall. Set your first course of rock so the top of the stones are just showing above ground level, this will give you a nicer looking base. As you build the wall, try to incorporate the larger stones along the lower courses, as getting bigger as you go higher will result in a less stable wall. Try to get a good mix of sizes as you go along with the stacking, this will help to avoid patterns. Patterns LOOK nice enough, until you break that pattern, then they really show up. Pack dirt in along the back side of the wall as you stack it to help it remain stable as you go up. Putting in a weed barrier along the back of the wall as you fill it will help dirt from eroding out from behind the wall as well. It really is not rocket science, but following these rules will help you achieve a nicer looking project when it's done.6. What Are the Three Most Common Cementing Agents for Sandstones?Sandstone is a sedimentary rock composed of mostly quartz compressed and cemented together. The cementing agents are the materials that hold the sandstone together. The composition of the stone and the cementing agent used will determine the strength, durability and weather-resistant properties of the sandstone. Silica cement, also called quartz cement, creates the strongest and most durable type of sandstone used for building. The cement is a result of the quartz grains overgrowing and expanding the crystallized forms until it runs into another quartz crystal. This type of sandstone typically forms in environments that have high-energy currents, such as beaches, marine bars and desert dunes. Calcite cement is the most common type of cement found in sandstone. The calcite cement typically forms in patches and does not fill all the gaps within the stone. This makes calcite cement sandstone very porous. Calcite is also soluble in wate, which can erode away the cement making the stone even more porous. Another common cementing agent in sandstone is iron oxide, also called hematite cement. The iron present in the cement will give the sandstone a distinctive red color. According to the Stone Care Techniques website, iron oxide cemented sandstone weather well in dry climates and become harder and stronger, resisting weathering and deterioration. Sandstone also has other cementing agents that occur in less common forms. These cementing agents include pyrite, barite and gypsum. These cementing agents form crystals between the particles of the stone. These cements produce a much softer type of sandstone with the particles able to be rubbed off the stone with your hand.7. how do you clean sandstone fireplace?I would use a soft bristled wire brush like a BBQ grill brush. These are brass or copper bristles and will not destroy the sandstone. You can buy a rotary wheel for a drill made of brass, but it will probably spin too fast and take off some of your stone work (I would not advise this method). Using a hand brush will take some time but it will be worth it.

Sandstone Getting Soaked with Water [duplicate]
My guess will be that it's mainly the effect of capillarity forces due to the porous quality of the stone surface. This might also be a good read1. Need help with a geology question!!!?The sandstone, shale, and limestone sequence is a facies change from a beach to marine environment, getting deeper as you go from shale to limestone. Since they are inclined, you know they've been tilted for some reason. The mudstone is horizontal so it was not tilted and is probably from a marine environment again. The basalt is from a volcano, then back to sandstone which means a beach environment2. What is a good way to remove Algae from large coarse rocks.?Pressure washer might do the trick, but will probably scar the rocks, sandstone is very soft, as far as rocks go. I have a Dremel, and would probably try a soft buffing wheel on a hidden area, to see what happens. You could ask at your LFS if they have any ideas. Surely they have seen this problem before and would know if there is a solution. You may just have to accept that these rocks are permanently discolored and forget about them. Good luck!3. Rusted sandstone, is there a formal name?Normally we call it red sandstone or perhaps hematitic sandstone. You would have to identify the minerals in the veins to know what the veins are composed of.4. In what geologic setting would you expect foliation to be absent?From any type of parent rock that lacks mineral diversity. Examples would be: Quartz sandstone Quartzite | Limestone Marble5. Where is the best place to buy limestone/sandstone? I live near Kent UK am new to buying for myself!?Dover is in Kent. Essex is around the Thames (get entry to by ability of way of Dartford Tunnel - no passport needed regardless of a few rumours :o) ) Kent additionally borders on London to the East and has borders with the counties of Surrey and Sussex. France is in basic terms around the channel - 30mins by ability of Le commute rail link6. How do I get gold dust out of sandstone?How well do you trust your jeweler? It is a lot more likely that your gold flakes are really mica7. What are the best downhill mountain bike tires for terrain with slippery mud, and sandstone rocks?Kenda Small BLOck 8 INtense Tire Systems8. I want to carve a sandstone canyon like Petra. Are there any regulations against that?That depends entirely on where you hmmm live and who owns that land. If it's your own private property and you own the mineral rights and have environmental permits, go for it.If it's not your land whoever owns it will likely stop you as soon as you pull out your first shovel or chisel. I want to carve a sandstone canyon like Petra. Are there any regulations against that?9. Lithic sandstone, micaceous shale, and coal:what is the tectonic setting for this rock suite?try read up some articles regarding continental rift basins. Which is most likely to be the tectonic setting of those listed rock type. Fluvial system commonly associates with continental rift basin. A fluvial depositional environment is required to generate lithic sandstone either associated with channel system of deltaic environment, shale usually deposited in open water bodies in pro-delta area it can be marine or lacutrine lakes. Coal usually developed in lower coastal plain environment that start-up from swamp or marshes10. How is sandstone cut to make buildings?Sandstone is hard but brittle. Sandstone will not break even if you park your jeep over it. But if you drop it, it will smash to pieces. Engineers and workers use special machines that have blades of either very hard stainless steel or diamond as both are very hard. Hope that helps you. If not, then do a little searching at google.11. What are the formulas for marble, limestone, sandstone and granite?Calcite Chemical Formula12. I had a well drilled here in WV 24 years ago. We have sandstone and limestone.?Check with the State Geological Survey in Morgantown. They have geologists and hydrologists on staff who probably can answer your question. They may even be able to send someone out to look at your well.

Best Way to Handle Low Tire Pressure for My Car?
There's no shame in going to a tire place and asking. That's what they are there for. It may be a puncture, a rim leak, or a valve stem that requires replacement. Driving on a tire that is under inflated can cause bigger problems. Let them resolve it while it's minor1. Tire Pressure light on in new car....?It just means your tire pressure is low. Get it checked out at the closest Toyota Dealer. Its free anyways. Your car is still under the 3 year warranty. You will just wear out your tires like crazy and get horrible MPG.2. How And Why Truck Tires Blow OutTire scraps are a common sight on many highways. Many truck crashes are due to a driver losing control of a semi after the tire blows out. Have you ever wondered why tires blow out or how you can prevent a tire blowout? Keep reading to learn more. Hotter weather makes tires more prone to blowouts. The most common months for tire blowouts are from May through October, but they can happen at any time of the year, especially in states with warm temperatures year round. When the weather is hotter and you are traveling at a high speed for a long distance while carrying a heavy load, tires are more likely to fail. Older tires are more likely to fail. Truck tires can last for thousands of miles, but they eventually need to be replaced like any vehicle. Semi tires are subject to more wear and tear compared to regular vehicle tires since they travel further more often and carry heavy loads on a regular basis. Tires should be inspected frequently to make sure they are not deteriorating. Underinflation is one of the most common reasons truck tires blow out. Without proper air pressure, the tire can not handle the weight of the truck and its cargo. Tires that are underinflated are more likely to flex beyond their limits, leading a tire to failure. Always check truck tire pressure before heading out on a long haul. Potholes and uneven pavement are all over the highway. If you hit a pothole or a bump in the road traveling at a fast enough speed, the pavement can cut through the tire and cause a blowout. Other times, the tire wo not fail when it hits the uneven pavement or pothole, but the hit will weaken the tire making it more likely to blow out at a different time. Although tire blowouts can happen to even the most prepared driver, there are a few precautions to take to help prevent a tire blowout: Perform regular tire maintenance. If proper maintenance is not done regularly, it puts everyone in danger each time the semi hits the road. Inspect tires before you hit the road. Check for cracks, holes or any other issues with the tire before heading out. Maintain proper tire inflation. Before you head out, check and make sure the tires are inflated to the proper air pressure. If it is an especially hot day, check the tire pressure each time you take a break. Tire pressure can fluctuate in extreme temperatures. Learn more tips for safe trucking on our blog.

Simple&efficient Slider Module for the Following Purpose
Views Slideshow is not a bad way to go. It will probably take some working with css/templates/views to get it to display the way you want, but it is the most used module, so if you find yourself up against a wall using it, there's a good chance someone's already has done it and has written a tutorial, or would answer a question. There are a few other modules out there you could look at. A quick search I found this page, which has a decent listAlso a very in-depth comparison on the different modules out there from drupal. org.1. Is there a common home vegtable that i can feed my red eared slider babies? and how should i prepare it?When I first got my turtles I tried lots of different fruit and veg, They just left the ones they did not like. Some of their faves are Pear just chop up a litle bit, carrot...they skin peelings, they do not seem to like strawberries, bananas or grapes. Their favorite is mango. They have never liked letuce tho!.2. Content Sliders (Nivo Slider) and SEOThe most important thing is what google sees. You do not care what JavaScript does to the images. You care what Google reads.Either use Fetch as Google or Lynx Web Browser to see how your website looks like from search engine perspective. So first thing first - you should use alt tags on your images. This way it's more google-friendly, and actually becomes valid W3C code.Secondly - as far as I can see on Nivo Slider website it's using quite clean HTML inputso you should not be bothered at all with the fact that is slices images. It could slice them, rotate, turn into a thousand pieces - it would not matter at all. Google cannot see that. What should interest you is the HTML code. So your best bet in putting the description would be by using the longdesc attribute on img tag. Alternative is that you use divs that are forced to be hidden. Like that:But I am not sure if they wo not collide with slider script, and doing things like that in general is a bad practice.Third way would be to use progressive enhancement, and either - put your text descriptions in a placeholder Div, or do not put it at all onto a website. In first case you would want to replace your placeholder div holding your content with actual slider AFTER the main content is loaded (either use simple JS content or AJAX). In second case you would add a slider into the proper spot after the main content is loaded (again: AJAX/JS) and in terms of SEO: Work as if slider would not be there. Prioritize content instead (which is IMHO the best thing you can do).3. do red eared slider turtles shells stay smooth?First of all, your question is extremely worrying. You bought a red eared slider because it was cute? Turtles need extreme care. I am not entirely sure about the adult turtles' shells staying smooth but I can tell you one thing for sure, your turtle's shell will go soft if you do not take care of it properly. Soft-shell is an illness that turtles can acquire from not being looked after properly. You were right about them basking to harden their shell. They do this for just the reason of preventing themselves from getting Soft-shell. For this you need a UVA and UVB lamp so that they can get the sun's nutrients. You need to get your turtle a big enough tank as well with a good filter. I suggest a Fluval filter and probably a 20 gallon tank to start. Try getting it used because it's cheaper. Make sure you are feeding your turtle properly (mostly proteins when it's young and progressively more vegetables as it ages). I hope that I am giving you information that you already know.4. Where should my baby red eared slider sleep at night?Turtles usually prefer to sleep in the water at night, where they feel less vulnerable. They like to rest just below the surface of the water, where they can lift their heads out to breathe. If you are concerned about the water depth, you can make a small platform just beneath the water or add some plants (real or plastic) or other decor that juts out of the water slightly so your turtle can rest on them while still being able to lift his head up to breathe. If you have a submersible water heater, you probably would not need the heat lamp at night. I have a Turtle Topper (above tank basking area) for my painted turtle. It has a platform hanging from the bottom that sits just below the water surface. He likes to sleep there and climbs up onto it when I turn his light off for the night. My big RES, though, basks in the evening and often stays on her basking dock to sleep if she's up there when the light goes out.
Water Tank Buying Guide: Price, Types, Vastu Placement & Maintenance Tips
In this article, we give you all the information on selecting a water tank and how to place it, according to Vastu ShastraSafe drinking water is a basic need and continuous water supply is needed for day-to-day activities. Often, municipalities do not supply adequate water throughout the day. So, home owners prefer to invest in a water tank for their house, to get water supply at all times.A water storage tank collects water and stores it for later use and access. Residential water tanks and overhead water tanks have become important, as they are convenient for people to access the water supply 24×7. Water tanks are also used as catchment tanks for rainwater.In India, water tanks are made from plastic, concrete, metal, fiberglass, steel and other materials. Nowadays, the plastic polyethylene (poly) water tank is the most popular for water storage, as it is lightweight, non-corrosive and leak-proof. If by any chance the plastic tank does have slight damage, it can easily be secured with a sealant. The water tanks can last up to 10 years or more, depending on the material used to manufacture them.Plastic water tanks in India come in various capacities and types - underground or overhead type. Plastic water tanks are available in various sizes such as 500-litre, 1,000-litre, 5,000-litre and it can even go above 1,00,000 liters. They usually come in cylindrical, square and rectangular shapes.Some of the water tank brands in India are Sintex water tank, RC Plasto, Storewel, Aquatech, Supreme, Penguin, Vectus, Sheetal, Jindal, Sarita, Kaveri, Lotus, Easy tanks, Neropure, Selzer and others.The water tank depends on the storage capacity, layers of the plastic used, brand, state, dealer, etc.Elevated water storage tanks are fitted underground and are ideal for storing water from rainwater harvesting and municipal water. The size of the underground water tank is usually larger than the overhead tank.See also: A guide to water conservation methodsOverhead tanks are placed over the rooftop of any house or apartment. These are popular due to its cost-effectiveness and easy installation. Water storage tanks above ground can be easily checked for leakage through visual inspection and are usually easier to access if repairs are required. With overhead tanks, one can have to access the water even without electricity. Once the tank is filled, the gravitational force maintains the necessary water pressure through the water system.Placement of water tank according to VastuWater is one of the five elements mentioned in Vastu Shastra, which plays an important role and if its placement is not correct in the house, then, it can create problems for the occupants. Vastu Shastra has specific directions mentioned for placing the water tanks.The ideal direction for the overhead water tank is in the south-west or the west corner of the house. If those areas are not feasible, then, place the tank in the south or the north-west direction. Ensure that the tank placed in the north-west is of a small size.According to Vastu, the overhead water tank must never be kept in the north-east corner. Placing the tank in the south-east corner or the center is also not advisable, as it can result in financial loss and cause accidents.An overhead tank should not have any leakage towards the left. In case there is any leakage, it is considered inauspicious as it can cause financial loss.Underground water tanks can be either towards the north or east. If the position of the tank is towards the north-east direction of the plot, it results in happiness, wealth and prosperity.Underground water tanks should not be placed in the south direction, as it may causes mental stress and illness. The south-east direction of the house is for the fire element and there should be no water tank in that area. Similarly, the north-west and south-west directions are not recommended for underground water.Avoid a water tank above the kitchen or bedroom. There should be different tanks for different purposes. As per Vastu, avoid digging an underground water tank on Tuesday.For a small family, a 500 to 600-litre water storage tank is enough and for a big family (depending on the size of the family) opt for a 700 to 1,000-litre tank. One also gets small tanks that have a capacity of between 100 and 300 litres.Water storage tanks come in different shapes. Vertical water tanks are better for groundwater storage purposes, while horizontal tanks are ideal for underground storage purposes. For household purposes, a vertical tank would be ideal, as rectangular and square tanks can fit in the corners and make best use of space. For large areas, cylindrical tanks are the best.Storage tanks are available in various colours such as black, white, green beige, etc. Black and green tanks are preferred, as they prevent ultraviolet rays and the growth of harmful bacteria.Always choose the high-quality low linear density polyethylene (LLDPE) material and food-grade plastic material. These are safe to use and are durable.Plastic water storage tanks are available with many layers. These multiple layers protect the tanks from the ultraviolet rays of the sun. The extra layers include the black middle layer and food-grade layers that make it safe for drinking water usage. So, opt for triple-layer tanks.Always select a well-known brand and one that has a warranty.See also: A quick guide on using water metersTips for maintenance and cleaning of plastic water tank• Ensure that the storage water tank is properly closed, to avoid any impurities or waste from entering. Regularly check for leakage of pipes and get them repaired immediately.• The purity of the water is also impacted by where it is stored. Whether it is a home building or a housing complex, the water tank should be cleaned and disinfected at least twice a year to avoid water contamination and to maintain health and hygiene.• To clean the tank fully, drain the stored water. Try to use it for some chores, rather than just wasting it.• Scrub the tank, to remove dirt and sediments. One can either use chlorine or liquid detergents to get rid of deposits and germs. After cleaning the tank, always ensure that the tap is left running for some time, to wash away the dirty water.• If one is unable to clean the tank oneself, it is better to hire professionals who will do high-pressure cleaning, such as vacuum cleaning, anti-bacterial spray, etc. and ensure it is thoroughly clean.I need information about Cold Salt Water Tanks and fish?Cold water salt water tanks can be hard to come by. There are very few fish on the market that are cold water. The only one I could fine was a Catalina Goby. They are marketed as warm water, but the live best at room temp. If you want any other cold water salt water fish, you might have to collect your own. If you want to go for Catalina goblies, a 30 gallon tank should be find. You can go smaller, but this is not recommend for beginner. I would do research on salt water tanks first. However, I do not think you will need a protein skimmer, just a good filter and some decor. Also, live rock and sand might not work because of the cold water( on second though, live sand should. Hope this helps!!
Which Characteristic of the Light Wave Does Jessica Change by Increasing the Intensity of the Light?
Which characteristic of the light wave does Jessica change by increasing the intensity of the light?(I think you've got the story muddled.) If there is a current, it will be proportional to intensity. If you increase the intensity at any fixed frequency, you increase the number of photons but te energy of each photon remains the same.— — — — — —A light wave has a frequency. But a photon, travelling at the speed of light, does not experience the passage of time. How can it exhibit a frequency then?Time only appears non-existent to the photon. To massive particles in the universe frequency is a property of the photon which dictates how, or not, it interacts with those particles. To use Mr Reiter's example of a rock, a rock has a mass but has no awareness of that mass. You on the other hand interact with the rock and can determine its mass etc. Not a brilliant analogy I know.— — — — — —INVISIBILITY- A POSSIBILITY?Have you ever read books like "Harry Potter" and "The Invisible Man" and found yourself wishing that you could turn yourself invisible? For many years, scientists have been working to turn that dream into a reality, and it looks like they've finally come one step closer to achieving it.Before we get into the science of invisibility, let us begin by understanding how our vision works. Normally, we see objects because light hits an object, bounces back, hits our eyes and sends the image to the brain which then makes sense of the image and voila. you have a cup in front of you. The colour of the said cup depends on the colour of light that it reflects back — if it's a green cup, it will absorb all wavelengths of light except green, which it will reflect and you end up seeing a green cup. Ok, as that's out of the way, let's get to the real deal.Scientists have experimented with many methods over the years to achieve invisibility. One such method that was devised made use of a new man-made material called metamaterial. Metamaterials are made of repeating patterns of composite materials like metals and plastics at a scale smaller than the wavelength of the phenomena that they influence. The reason they are so special is that their geometry, orientation and arrangement gives them new properties that cannot be achieved in natural materials. One of the properties is manipulation of electromagnetic waves — whether it be blocking, absorbing, enhancing, or bending these waves. In this list of properties, the one which is most useful to achieve invisibility and the very reason for which these materials are used, is the ability to bend electromagnetic waves like light. So, now the question is, "Why is bending of light so important to this discussion?" Well, the answer to that can be explained by going back to the basics.In order to see an object, light has to interact with it. Therefore, we can make the simple inference that in order to make an object invisible, light should not be allowed to interact with the object, but instead be made to bend around the object so that what you see is not the object, but what is behind the object, thus making it seem invisible. This is where the concept of negative refractive index comes into place.We have all seen and heard of "refraction". It is essentially the bending of light when it travels between media of different densities. Normally, the refractive index of air is 1 and in other materials it is greater than 1. This means that when light travels from air to another material, it usually bends towards the normal drawn to the surface of the material. Now, what if there was a way to manipulate the refractive index so that it becomes negative? This can be achieved by altering the internal structure of a material on a small scale, like in negative index metamaterials or left handed metamaterials to the point where we can switch the positive refractive index to negative, thus enabling us to manipulate the direction of bending of light.In 2007, a research team at Maryland's A. James Clark School of Engineering used plasmon technology to create the world's first invisibility cloak for visible light. The invisibility cloak device was a two-dimensional pattern of concentric rings created in a thin, transparent acrylic plastic layer on a gold film and only 10 micrometers in diameter. But the cloak used a limited range of the visible spectrum, in two dimensions. It would be much harder to achieve invisibility in three dimensions since scientists would need to control light waves both magnetically and electronically to maneuver them around the hidden object. More recently, in the University of Texas, scientists have been successful in concealing an object to microwaves. It was called metascreen and was made of a 66 micrometre thick polycarbonate film that supported an arrangement of 20 micrometer thick copper strips which looked similar to a fishing net. In the experiment that was carried out , when the metascreen was hit by 3.6 GHz microwaves, it re-radiated microwaves of the same frequency that were out of phase, cancelling out reflections from the object being hidden. This could have a lot of applications in radio communications, weather tracking and in health care. The material, called Quantum Stealth, is currently still in the prototyping stage, but was developed by the company's CEO Guy Cramer primarily for military purposes, to conceal agents and equipment such as tanks and jets in the field. Unlike traditional camouflage materials, which are limited to specific conditions such as forests or deserts, according to Cramer this "invisibility cloak" works in any environment or season, at any time of the day.Check out this video on Quantum Stealth:Other than these technologies, methods like spectral cloaking and active camouflage have also been developed. In spectral cloaking, light is not made to bend around the object, instead it shifts one spectrum of light to another and then shifts it back once it reaches the other side. If for example, we take the cup we mentioned before and shift the green light to another part of the spectrum that is not reflected by the object, say blue, then no light will be reflected and the object will not be visible. The device then shifts the green light back to reverse the process once the light reaches the other side. This method eliminates any kind of distortion that could be caused by bending of light around the object and hence is more effective. The cloaking device is constructed from two pairs of two commercially available electro-optical components. The first component is a dispersive optical fiber, which forces the different colors of a broadband wave to travel at different speeds. The second is a temporal phase modulator, which modifies the optical frequency of light depending on when the wave passes through the device. One pair of these components was placed in front of the optical filter while the other pair was placed behind it. This method of spectral cloaking could be applicable to securing data transmitted over fiber optic lines and also could help improve technologies for sensing, telecommunications, and information processing .It could also be used for selectively removing and subsequently reinstating colors in the broadband waves that are used as telecommunication data signals which could allow more data to be transmitted over a given link, helping to resolve impairments due to increased demand in data. In 2003, scientists at the University of Tokyo created a prototype active camouflage system that makes use of a material impregnated with retroreflective glass beads. The viewer stands in front of the cloth viewing the cloth through a transparent glass plate. A video camera behind the cloth captures the background behind the cloth. A video projector projects this image on to the glass plate which is angled so that it acts as a partial mirror reflecting a small portion of the projected light onto the cloth. The retroreflectors in the cloth reflect the image back towards the glass plate which being only weakly reflecting allows most of the retroreflected light to pass through to be seen by the viewer. This system works only when viewed from a certain angle. In conclusion, even though an invisibility cloak that could make objects, much less humans invisible has not yet been perfected, we are on the right track. The very fact that we have come this far goes to show that with technology and a creative mindset, anything is possible.Follow us for more of amazing and latest science and technology articles.
