Fiber reinforced polymer (FRP) composites or advanced composite materials were first used in the civil engineering during the late 1960s to build composite buildings. The construction industry at that time was of the opinion that composite materials should be used as concrete reinforcement. However, it was not until the mid-1980s when the structural design engineers and researchers throughout the world put efforts to investigate the practical use of FRP composites and its variants such as GFRP in building concrete members.

The construction industry was familiar with the unique characteristics of FRP materials, such as high strength and corrosion resistance at the time when they started exploring the potential applications of FRPs in the construction or rehabilitation of concrete structures. However, the high initial cost was really a drawback. In the late 1980s, FRP composites witnessed a breakthrough when they were used in the field of flexural, seismic retrofitting, and shear strengthening of deteriorated concrete structures. Despite the promising results, composite materials are still struggling to fully accepted by all areas of the civil engineering industry.

In the seismic retrofitting and rehabilitation area of civil engineering, the cost to implement composite materials is only a relatively small percentage of the overall cost. FRP materials are inherently lightweight making it possible to undertake fast on-site fabrication which reduces production costs. Its low weight offers an economic benefit in reducing closure period of roads and erection time.

Following the rising need for sustainable and environmentally friendly construction materials, The structural engineers now paying attention to mechanical and in-service properties of FRP and its components. The manufacturing techniques and long-term loading characteristics of FRP have been the point of discussion in civil engineering circles. Looking at the future, and considering the unique qualities, composite materials are likely to play a key role in building sustainable concrete infrastructure.

Undoubtedly, composite materials have become a key component of the construction industry because of their durability, high strength-to-weight ratio, accelerated construction, low life-cycle costs, and superior resistance to corrosion and fatigue. The scope of FRP materials is also expanding in terms of civil infrastructure applications. The civil applications of composites include bridge decks, seawalls, runways, bridge strengthening and repair. Composites are also valuable material when it comes to seismic retrofitting and building marine waterfront structures.

Being a contractor or structural engineer, you should explore FRP and its components such as GFRP fiberglass rebar. These materials can really help construction industry construct maintenance-free concrete members with a lifespan of 100 years.

Sooner or later in the coaching process there comes a time when the client starts going in circles or simply doesn’t know which step to take next. In circumstances like this, the method called “meta-view” comes in handy and I believe each coach should have it as part of their “tool box”.

“Meta-view” is a symbolic view from “high above”, whether it is from an airplane, helicopter, the top of a mountain, or just a platform. When using this method, the coach invites the clients to look at their situation from a higher perspective, turning their attention to the “bigger picture” of their lives, rather than the obstacles obvious at that moment.

This exercise is very useful in any coaching process. Firstly, it gives the clients the opportunity to try something new. Secondly, the clients can fully experience the benefits of coaching – because this sort of exercise is exactly what can make a difference in any client’s life! (It is not usual for people who have not been through coaching to use a method like this in their everyday lives!)

Thirdly, the clients can appreciate the work of their coach, who understands that now is the right moment to steer the clients away from the nitty-gritty of their daily life and focus instead on what really matters to them in the long-term and what their true goals and desires are.

It is easy to get engrossed in heavy thoughts under the burden of everyday life but the ability to soar above that all and see all the connections that make our life what it is, and what can make it different and better, is the true benefit here. To top it all, once the method gets tried in coaching, the client can keep using it in later life, whenever needed.

Field of view is the amount of area that can be viewed through binoculars. The amount of area is the total left-right footage seen by your eyes through the binoculars.

The binoculars field of view is normally stamped on the binoculars and is typically expressed as “360FT/1000YD”. Which is read as “The field of view for these binoculars is 360 feet wide at a distance of 1000 yards”.

This means if your target was centered 1000 yards away, you would be able to also view 180 feet of terrain on both the left and right side of that target. Or if you were just scanning the terrain, you would be able to observe 360 feet of coverage at any given moment.

Better quality binoculars tend to have a field of view between 315 and 390 feet at 1000 yards. Those are general guidelines, but will satisfy field of view requirements for birding, hunting, marine activities, and most spectator sports.

Linear and Angular Field Of View.

Both of these readings will result in the same measurement at your target distance of 1000 yards.

Linear field of view is most commonly used as it is expressed in feet and yards in a factual statement (330FT/1000YD). That expression can be quickly understood to mean that at 1000 yards your will see 330 feet of left-right terrain with the binoculars.

The angular field of view is expressed in degrees. As an example, a reading of 6.3 degrees means that the view from the binoculars will expand outward 6.3 degrees from each of your eyes.

Conversion to either linear or angular field of view is done with the factor of one degree being equal to 52.5 feet.

Angular degrees of 6.3 will convert to 330.75 feet (6.3 degrees X 52.5 = 330.75 feet).

Linear feet of 330.75 will convert to 6.3 degrees (330.75 feet / 52.5 = 6.3 degrees).

Magnification Versus Field Of View.

The magnification and the field of view are two binocular features that work in opposition to each other. In general, the more powerful binoculars (12 X 50) will have a smaller field of view (290FT/1000YD), while less powerful binoculars (8 X 42) will typically have a wider field of view (380FT/1000YD).

Most binoculars tend to fall into either the 8X or the 10X magnification ranges because at higher power binoculars often have poorer quality images and smaller fields of view.

The most common linear/angular fields of view binoculars are between 6.0 degrees/315 feet and 7.5 degrees/390 feet. Wide angle binoculars begin at 8.0 degrees/420 feet and work upward.

Everyone needs friends in the society. Friends can give you a rest station of your heart if you are tired about your daily affairs. Friendship is really a valuable relationship in human beings. Friends may not be many but must be really true friends. Just as the saying goes, “a friend in need is a friend indeed”. So if we have lots of good friends we will find life will be beautiful and wonderful.

If you have a good friend then you can confide your feelings or thoughts which maybe can not tell others to him or her freely when you are in trouble or in bad mood. You do not have to hide your emotion in your heart. You will find your friend is your best listener and adviser when you are telling. If you came across something and need help then you can turn to your friends for help. Because he or she will try his or her best to help you and make you get out from the hardship. If you are not happy your friends will make you laugh. And at last you laugh together. If you have good friends, you are supposed to care about them also. Friendship needs mutual efforts to keep, not one person’s effort.

So if you have good friends just try to do something beneficial for him or her. Let them feel your love, your care and your happiness. It’s not you always accept their care and love you also should do something for them. And the relationship between you will be better and better.

If you have some really good friends just try to cherish the valuable relationship between you. Cherish everyday you spend together. Cherish his or her kindness to you. Because there are not many people like them treat you so kind in the world. So just treasure the valuable friendship between you all your life.
