Q. 2. Write a detailed report on any two chemical Hazards happened in Oman or in the Gulf region.

analyze climate change and the answer would give the environmental problem as a government representative.

1. How is deforestation and corruption affecting communities in Cameroon?

2. Who are the main actors and stakeholders (participants) in forestry industry in Cameroon?

3. What are some of the causes of deforestation in the Amazon and why is widespread deforestation bad?

4. What message is Harrison Ford trying to communicate in the documentary about palm plantations in Indonesia and elsewhere?

5. Why is Palm Oil problematic, what are some items that you might use on a regular basis that have palm oil or palm derivatives in them?

6. Would you be willing to reduce your consumption of or avoid products with palm oil derived ingredients or palm derivatives that are not sustainably produced?

7. Who is Ron Finley (guerilla gardener) and what are his goals?

8. What is a "food desert" as it was referred to in the Guerilla Gardner video with Ron Finley?

9. What is the difference between industrial agriculture and sustainable agriculture?

10 What are some ways in which agriculture and food production can be more sustainable?

The isothermal reaction of A to B is a first order reaction in A. A 5,000 liter plug flow reactor is fed with A at concentration of 4 gmol/liter and volumetric flow of 800 L/min. At these conditions the conversion of A is 95%. We have two CSTRs that are 2000 and 7000 liters and can be place in series to replace the PFR.

a. Can the two CSTR’s in series provide 95% conversion in replacement of the PFR? Select a configuration for the two CSTRs and support your conclusion with calculations.

Come up with a hypothetical scenario, illustrating the legal concepts of environmental law. There are no right or wrong answers, but for your own learning purposes, try to precisely and explicitly identify specific legal concept(s) by name and provide examples to support whatever points you make. 100 words or more

We have a heat exchanger tube whose speed is doubled. How will the α-value and the pressure drop be affected by this, ie how much will their value increase as a percentage? What circumstances (factors) decides the choice of optimum speed?  

1. Ethylene is produced by the dehydrogenation of ethane and the following reactions took place

C₂H₆ --> C₂H₄ + H₂

C₂H₆ + H₂ --> 2CH₄

Using molecular balance. Calculate % Yield of C₂H₄, if the % conversion of C₂H₆ is 80 % and the selectivity, mole C₂H₄ per mole CH₄, is 1.75. Calculate also the % composition by mole of the product gases.

Two continuous stirred-tank fermenters are connected in series, the first having an operational volume of 100 L and that of the second being 50 L. The feed to the first fermenter is sterile and contains 5000 mg/L of substrate, being delivered to the fermenter at 18 L/h. If the microbial growth can be described by the Monod kinetic model with µm= 0.25 h-1 and Ks = 120 mg/l. What would happen if the flow were from the 50 L fermenter to the 100 L fermenter?

1. What do you think is the ideal world human population size? Is this different than humans’ carrying capacity? Explain.

2. What policies or methods might encourage smaller families in developing countries? Focus on positive changes that encourage CHOOSING smaller families instead of focusing on government-mandated requirements.

3. In many developing countries, larger families are desired, while developed countries tend to prefer smaller families. What factors influence these decisions?

4. A declining population rate has its own problems. Discuss what issues may arise for the country as it transitions to a falling fertility rate.

5. Who do you think has a bigger role in curbing the effects of human population growth: the countries with high fertility rates or the countries with high consumption rates? Explain.

How can the temperature of the incoming air affect the effect of the gas turbine? Describe this by drawing a T-s diagram. Also draw a T-s diagram for how the compression ratio affects the effect and a T-s diagram for how the combustion temperature affects the effect.

Which trade goods from the past are still in high demand today from Sea roads, Silk Roads or Story of India?
