Light rays that are falling on us have three components. They are the ultra violet rays, the visible light we generally see and the infra red rays. An infrared filter blocks all lights except infrared rays to pass through the filter. These filters were initially developed for taking photographs using infrared light. The films used were sensitive to infrared lights. Infrared photography has been extended to digital cameras. These cameras use image sensors which are sensitive to infrared lights.

Besides use in infrared photography, these filters are used in many other areas.

These filters are being used in the industries. These filters enable to see through objects that are not visible to naked eyes under normal light. Water and other fluids absorb specific wavelengths. By using infrared filters, it can be ascertained whether a container has been filled. By using these filters, we can see through the labels to detect the fluids stored inside or we can detect the presence of any foreign materials.

These filters also find application in security and surveillance applications. By using infrared light source (which will not be visible to the naked eye) and using infrared sensitive cameras or binoculars any movement made in the darkness of the night could be easily monitored.

Similarly, by using these filters and infrared light source, it would be possible to keep watch on the movement of wild animals in the forest in the night. The hunters could also utilize this facility for game hunting in the night.

These filters used along with an infrared light source could enable the parents to keep watch on their children without turning the lights on.

It has been seen that using a camera with an infrared filter in the daytime, sometimes we could see through the clothing.

For some applications, it may be required to that the filter would reflect infrared light instead of allowing it to pass through. This type of filter has been used in Silver Cloud’s Heat Shield display filter windows so that heat of infrared light does not affect in outdoor applications.

Digital camera sensors are generally sensitive to infrared lights. This sensitivity could interfere with its functioning while taking photographs under normal lighting. Therefore, to improve the quality of pictures taken by these cameras, they are fitted with infrared filters which block infrared lights. These cameras would not be suitable for taking infrared photography.

For taking infrared photography using digital cameras, these blocking filters are removed and infrared filter is fitted in these cameras which allow only infrared light to pass. Special digital cameras are being developed for taking infrared photography to be taken from satellites or for taking photo using infrared radiation (Thermographic camera).Light rays that are falling on us have three components.

Landscape Design

Designing your own landscape, can be both exciting and challenging. If you are considering such a project, here are some practical ideas and suggestions.

Planning the Project

Planning your landscape design is the first and most important step. Take the time to gather the information you will need to make your decisions on the elements you wish to include in your landscape design. Will you want a deck, patio, foot paths, walkways, a pond? What type of plants, trees, flowers, and ground cover will you want to use? You should research books, articles, and landscape design magazines to help you make these decisions. This will pay off in the end by saving you money, time, and frustration, enabeling you end up with a beautifully finished project to be proud of.

The Design

The landscape design is your next step. You will need to make a layout of the area to be landscaped, as close to scale as possible, and with accurate measurements. Many landscape design planning guides that will give you step-by-step instructions are available on the internet for free, and books or eBooks are abundant. Once your landscape design layout is done you can began to place your elements on the layout pad. This should be your first or preliminary plan and as you progess, changes can be transfered to your secondary or updated plans. Changing your mind often is just fine. After all this is just on paper at this point and you have not spent any money or performed any labor yet. Experimenting with a few plans is necessary before you come up the final landscape design. A well planned landscape will never look the same in different seasons. Plan your landscape design to change with the seasons. You should attempt to design your landscape as maintenance free as possible.

Landscape Design Software

If it is hard for you to visualize your finished landscape design by just looking at your layout, there is some very good landscape design software available. Much of the landscape design software was originally developed for professional landscapers, but since has been modified for the beginner who wants to do-it-themselves. There are many do-it-yourslef landscape design software programs available today. Landscape design software lets you see a virtual picture of the landscape design and enables you to move items around and see the changes you make come to life. Some software allows you to import a photo of your home or building and designs the landscape around the photo. Most landscape design software programs offer advise on using and placing the many different elements available today in your landscape design. A well designed landscape will always change with time, abd some of the landscape design software available will allow you to view your landscape as it matures. You can see what it will look like 5 or 10 years from now when the trees have grown and the plants matured.

Gardens

Many people like to incorparate a garden in their landscape design. Gardens can be tucked away in the corner of an area, or be the focal point of the entire landscape design. Gardens can even be stragecly placed among the plants, flowers and trees so they blend in with the entire landscape design. If you like to garden, dont overlook all the garden design possiblities when planning your landscape design.

What Does FSC Certified Wood Mean?

by

Herman Brickovich

The Forest Stewardship Council (FSC) is an intercontinental, non-governmental charitable organisation, formed in 1993 to encourage responsible management of all of the Earth’s forests. Different countries have divisions of the organisation operating in them.

The main benefit of the FSC is that forests are protected for generations to come and people know that when buying wood that’s FSC certified, they are not contributing to deforestation and climate change.

Deforestation is a large challenge for the world. If forests aren’t properly maintained, we will end up losing an irreplaceable and essential part of the world’s ecosystem. This not surprisingly would be a problem on a world level and one that we must avoid.

Illegal logging is one part of the problem. People desperate for money chop down virgin forest and clear trees faster than they can be replaced. No respect is given to local wildlife or native peoples that rely upon the forest for all of their requirements. Sad to say some of this timber will find its way into the UK where end users are sometimes ignorant as to where the timber has come from.

People can trust the FSC labelling of timber. The certification relates to forest management and chain of custody. A properly managed forest will be maintained with thought for wildlife, people and the environment and trees that have been cut down will be replaced by natural means or replanted. Parts of the forest will be protected from logging to protect the rare plants and animals that happen to be part of it and to protect holy sites of indigenous people. Workers will be acquired locally, trained properly and paid fairly.

The chain of custody tracks the movement of the timber from forest to end supplier. Every link along the way is tracked and certified to ensure that everyone is compliant with the FSC’s priciples.

People are able to see the FSC logo (a tree that has a tick) on anything from wooden furniture, paper and oak flooring to charcoal and venison.

If you’re purchasing wood or wooden producs, be certain that they contain the FSC logo and this means that you will be certain to have an environmentally sound product.

When shopping for wood products such as

oak flooring

, check for the FSC logo. Timber suppliers such as

Vastern Timber

have FSC certification.

Camping is fun. There is no doubt about that. But as harmless as camping may seem compared to extreme sports and activities like bungee jumping or rock climbing, you still need to always be cautious about your safety during a camping trip.

Below are some safety guidelines to ensure that you have an enjoyable and safe camping experience.

1. Buy durable and high quality camping gears that you can rely on even during trying times. Don t opt for cheap camping equipment just to save a couple of cents because you ll be in bigger trouble if your poor quality tent falls apart in the middle of a sudden storm. For example, Coleman can guarantee you of sturdy camping gears that will make you feel that you re always in safe hands.

2. Don t leave food unattended in the camping site for this may attract bears. If only bears are like Yogi Bear who just steals picnic baskets and makes funny wisecracks afterwards, then you don t have any problem. But it s different in real life. Close encounters with bears and other wild forest creatures is one thing you want to avoid during camping trips. Be sure to put away any leftover food or food container before you go back to your tent or before you go to sleep.

3. Don t eat inside the tent. This is a precaution to avoid the small but terrible insects like ants that will follow trails of crumbs inside your tent and will possibly feast on your skin on too. So if you don t want to be waken up in the middle of the night or to wake up the next day with red stinging ant bites on your body, say no to a late evening snack inside the tent.

4. Speaking of insects, another kind you should protect yourself from are mosquitoes which are common residents in forest areas. These dreadful insects being as tiny as they are can cause different kinds of diseases like malaria and dengue. Be sure to pack sufficient insect repellent and to bring a tent with mesh screens to protect yourself from mosquito bites.

5. Never use or even attempt to light up candles or gas lanterns inside your tent. This is extremely dangerous and may start a fire. Opt for safe catalytic heaters like the Coleman SportCat Perfectemp Catalytic Heater with InstaStart Technology designed for indoor use or to be used in enclosed areas such as a tent. It is a good idea to place this heater in an elevated area like on top of a cooler so that it does not come in contact with the tent s floor and minimizes the risk of you rolling over on it as you sleep. Keep it at least two feet away from anything that can be harmed by heat.

6. Pick a safe and well known campsite. Don t go for deserted areas that are very far from civilization. There are many camping parks that have guards to keep you safe even at night. But if you re the adventurous type who loves to go camping in the middle of the forest, it is wise to choose spots that are recommended by fellow campers or have been tried by friends and family.

Remember, to always opt for the safe side. As they say, it s always better safe than sorry.

Among the most important and dramatic changes you may make to your home’s interior is floor refinishing. There are many benefits you get when you do this.

Benefits of floor refinishing:

Floor refinishing is simpler to do as compared to replacing the flooring. It also requires less time, and is less expensive. It will not only increase your home’s value but when at some point you want to sell the property, attractive refinished flooring is a plus. It is going to pull in potential buyers and is going to allow you to set a higher price for your home. Additionally, the cost of refinishing your wood floor may be done for far less as compared to the cost of replacing it.

The methods of wood floor restoration include recoating, refinishing and replacing. You should consider recoating the hardwood flooring finish when it’s not worn out entirely and it has a dulled surface with only some minor imperfections or scratches, and no stains. A recoat may quickly restore the aesthetics of your floor, and put off the need for a complete floor refinishing job.

How to recoat a wood floor

You should prepare the surface of the floor by scuff-sanding the floors using a buffer. The abrasive process roughs up the existing finish to make sure the next finish or coat adheres to the flooring. When the finish is roughed up, you apply water-based polyurethane to your buffed floor. This may be done in about three hours. Whereas oil-based polyurethanes normally cost less, every coat will take nearly eight hours to dry. This process is quite simple, fairly quick, and is less costly as compared to full refinishing.

When you should do floor refinishing

When your floor is damaged or worn with major wear, gaps in the floor, deep scratches or minor buckling all the way through the finish down to wood, then it will be necessary to do full floor refinishing for hardwood floors. This process includes sanding off completely the old finish, down to the bare wood floor, and leveling the surface of the floor. At this point, you may change existing wood to the color of your choice and repair cracks, correct minor imperfections in the wood, and remove stains. The final step is applying new protective sealant so as to maintain the real beauty and attractiveness of your floor.

How often can you do floor refinishing?

Whether you are refinishing or re-coating, it’s recommended that a new or fresh coat of protective sealant should be applied each and every two years, or whenever your floor looks worn. You should stick to the routine, and your floor will not wear out.
