Jaw crusher is mainly used for crushing various ores and large materials with compression strength not more than 320Mpa into medium-sized grains; and is widely applied in mine‚ metallurgy‚ construction‚ road‚ railway‚ water conservancy‚ chemical industry‚ refractory material and ceramic etc. We should install the jaw crusher above the concrete foundation in order to reduce the vibration; between the machine base and rack it needs to plus skids or rubber.

A study of the organization’s objectives helps to understand how it is likely to respond to changes in its environment. It is often assumed that business organizations will always try to maximize their profits through a combination of maximizing revenue and minimizing costs. The profit maximization objectives must be qualified by a time dimension. A firm that pursuing a short-term profit-maximizing objective may act very differently to one that seeks to maximize long term profit. This may be reflected

If both the objective function and the constraints are linear‚ the problem is referred to as a linear programming problem. 2.

In religious absolutism‚ most world religions accept that God created the universe. Most Christians also believe that Bible is the inspired of God‚ which is absolutely right.

OBJECTIVE MORAL TRUTH There are many views on moral truths‚ which causes major turmoil in the world we live in. Were this a simple subject world peace would most definitely be solves in an instant‚ and pointlessly killing each other would cease. The question is are there universal objective moral truths? Are there irrefutable‚ accepted by everyone‚ moral issues that can be universally agreed upon by everyone no matter what age‚ race‚ color or nationality? My answer to that question is no‚ there

of a variable is equivalent to maximizing the variable itself. Therefore ln(Q)=(2/3)ln(L)+(1/3)ln(K)‚ a more convenient expression‚ is the same as maximizing Q. Therefore the objective function for the optimization problem is ln(Q)=(2/3)ln(L)+(1/3)ln(K). Step 1: Form the Langrangian function by subtracting from the objective function a multiple of the difference between the cost of the resources and the budget allowed for resources; i.e.‚ G= ln(Q) - λ(wL+rK-C) G= (2/3)ln(L) + (1/3)ln(K) - λ(wL+rK-C)

A blue seventh place athletic ribbon hangs from my mantel. Every day‚ as I walk into my living room‚ the award mockingly congratulates me as I smile. Ironically‚ the blue seventh place ribbon resembles the first place ribbon in color; so‚ if I just cover up the tip of the seven‚ I may convince myself that I championed the fourth heat. But‚ I never dare to wipe away the memory of my seventh place swim; I need that daily reminder of my imperfection. I need that seventh place. Two years ago‚ I joined
