Bush encroachment definitely has a serious impact on the agricultural production and economy of most countries.

Bush encroachment in Namibia affects 26 million hectares and has led to a 60 percent decline of commercial livestock over the last 40 years, causing losses to the national economy. In South Africa bush encroachment affects the agricultural productivity and biodiversity of 10-20 million ha.

Bush encroachment suppresses grass in grazing areas and reduces the capacity for livestock. Some serious cases of bush encroachment is making large areas of land unusable.

I'm not sure how you'd do this in C++, but I could have a go at it in php since that's what I know.

You know that Pi is approximately 22/7, in php you can use the pi function.

You'd need your input(radius) to come from a form if it was web-based, which is simple enough.

perimeter = 2nr = 2 x (22/7) x r

function getPerimeter ($input) {

$input = $_GET['formInput'];

$pi=pi();

$perimeter = (2*$pi)*$input;

return $perimeter;

}

According to the Heisenberg uncertainty principle if the position of a moving particle is known velocity is the other quantity that cannot be known. Heisenberg uncertainty principle states that the impossibility of knowing both velocity and position of a moving particle at the same time.

Since steam is a gas (water vapor). This depends on the pressure and temperature of the steam. PV = nRT.

Hinge is a joint. It is designed to join two 'arms' together while letting them move freely. A lever is when a pivot, load, effort is present. Although hinge itself is not a lever, but taking our biceps as an example, that would be a Class 3 lever

The difference is base on the requirement of their0 application.

Acrylic is hard when at room temperature, but becomes pliable when heated. It is sometimes transparent and comes in a range of colours. It can be bent into a shape, but it can snap if bent too much. It is easy to cut and not very flexible (depends on the thickness) and takes a long time to file down. However, when machining acrylic, make sure to lower the RPM of your drill or milling machine to prevent melting the acrylic. Also, use an endmill that is not a spiral, but has a straight cutting blade to prevent shattering (a common phenomenon with acrylic).

Reduce the harmonic current in the electrical supply system.

A moment can be anywhere from a few seconds, up to a minute. Generally, a moment is defined as a point in time lasting from 1-3 seconds.

In Old English, a moment was an exact measurement of time being 1.5 seconds or 1/40th of one minute. However, in more modern English usage it has simply meant an inexact and brief length of time.

The terms MIS and DSS stand for Management Information Systems and Decision Support Systems respectively. There has been a lot of talk regarding these two, whether they are actually the same thing or if there are any significant differences between the two.

MIS is basically a kind of link to facilitate communcation between managers across different areas in a business organization
. MIS plays a pivotal role in enabling communications across the floor of an organization, between various entities therein.

DSS, many consider, is an advancement from the original MIS. However,this is not the sole difference between the two. While there may not be too much separating the two, the difference is still there,as is apparent when we say DSS is an advancement over MIS.

The essential difference between the two is in focus. DSS, as the term indicates, is about leadership and senior management in an organization providing good, reliable judgment as well as vision. MIS, on the other hand, is about focusing on the actual flow of information itself.

The decibel scale is used to measure the loudness of sound.

The financial flexibility, the business risk and taxes are some of the factors that influence a companyâ??s budget. The management style is also important.

Two voltage sources in series can either add up or cancel out depending on which way round they are orientated. If the two positive or the two negative terminals are connected together, the overall voltage is the subtraction of the two. If the positive terminal from one supply is connected to the negative terminal from another, the overall voltage is the sum of the two.

Fulton's steamboat was built on the East River at the ship yards of Charles Brownne. After disappointments and delays, Fulton left New York on his steamboat for Albany on August 17, 1807. He made the trip in thirty-two hours and successfully demonstrated to the world the possibilities of steam navigation.

One formula used to convert psi to bar is:

1 psi

= (32.174 lbm /1 lbf s2)x(0.45359237 kg /1 lbm)x(144 in2/1 ft2)x(1 ft /0.3048 m)

x(1 m s2 /105 kg)

= 0.06894747 bar

So 1 bar = 14.503795 psi

The Math behind it.

As psi is an imperial unit and bar is metric unit, we some constants

1 lb = 0.45359237 kg

1 ft = 0.3048 m

1 ft2 = 12 in x 12 in = 144 in2

And we have to rearrange some units

1 bar = 105 Pa = 105 Nm-2

And N = kg ms-2

so 105 Pa = 105 kgm-1s-2

Also note when applying newton's second law using imperial units we need to use a gravity constant 32.174 lbm /1 lbf s2

Metric

m x a = F

1 kg x 9.81 ms-2 = 9.81 N

Imperial units

m x a = F

1 lbm x 32.174 fts-2 ≠ 32.174 lbf need to use gravity constant gc

m x (a/gc) = F

1 lbm x (32.174 fts-2 / (32.174 lbm /1 lbf s2) = 1 lbf

Get a kit, and set it up.... There are certain places that you can get a roller coaster kit. Now I had to order mine from FUTURE INVENTORS of AMERICA.

You may not have one where your at but there are other places you can get them at. Just look and you find one.
