Environmental issues have become critical concerns of businesses in recent years. Therefore, Environment Ministries in different countries is urging organizations to consider adopting the ISO 14000 Environmental Management Standards. Evaluate FOUR (4) challenges among the Malaysian companies to receive ISO14000 so explaining in detail ?

2. There are two primary methods of building up a solution to an engineering model, 1) analytical, and 2) numerical. Provide a description of each of these methods, explaining in detail what they are being employed for, when they would be employed, and why a given method would be employed rather than the other. answer should be relavent to engineering system unit please.

A 1000 litre containment tank catches the outflow from a processing apparatus which has 800 litres of water with 2 g of chemical agent dissolved in it. Additional supply comes into the tank at 3 litres/hr containing 5 g/litre of the chemical agent. The solution leaves the containment tank at 3 litres/hr. When the amount of chemical agent in the containment tank reaches 500 g, no more supply is allowed to enter the system. Instead, fresh water is input into the tank at 2 litres/hr; and at the same time, the outflow is increased to 4 litres/hr. How much chemical agent is held in the containment tank at any time t. Assume all liquids are well-mixed. (10 marks.) Please provide the explanation of the method and as much as step uh can with proper calculation.

1. Provide a detailed explanation of the process that should be taken when testing an engineering model. In your explanation describe what you are doing at each step and why you are doing it. please provide answer related to engienerring system unit

can you give me a conceptual framework on the research topic "Impact Of Variation Order in Construction Project?"

In your city, the number of traffic accidents is relatively large, propose a step by step procedure to improve traffic safety

Mode of instability in rock mass is mostly controlled by the orientation and type of discontinuities. Thus, the selection of stabilization must be made based on the mode of instability. Answer the following question:
a) Name FOUR (4) basic mechanisms of rock slope instability.


b) List the THREE (3) main parameters that control the stability of a    jointed rock slope.

It is a common practice to install rock bolt together with cement grout. For an unstable slope face why such practice is highly recommended. What is the purpose of cement grout in rock bolt installation?

An area of 200 ha will be used to grow Alfafa (47 ha), Corn (70 ha) and Tomato (83 ha). The latitude of the area is 380 N. If the monthly temperatures for July, August and September are 21, 20, and 190 C, respectively, calculate the total consumptive use by Blaney-Criddle.          

At the end of the CD triaxial pressure experiment on a normal consolidated clay, the sample was defeated along a plane of 570. When another sample with the same properties was tested in the CU experiment, the pore pressure in the defeat was measured as 85 kPa. According to the cell pressures (63) 200 kPa in both experiments;
a) At the end of the A = CD experiment, find the effective internal friction angle and the difference in prime stress.
b) At the end of B = CU experiment, find the total angle of internal friction and angle of defeat plane.
c) In the C = CU test, find the shear strength in the plane of failure.

in table 1 the failure load obtained from the compressive strength  test at the laboratory are presented. sate whether those values are satisfactory according to TS EN206 1;2004 or not verify your results. concrete class C35. Determine also standard deviation and variance
