I just need you opinion guys, essay will do. THANKS!

What is this asking ???

A surveyor compares the bearings at two ends of a line underground by using a gyrotheodolite. The results at each end can be compared after they are corrected for grid convergence, meridian convergence, deflection of the vertical and index error in the instrument. Could the effects of deflection of the vertical be ignored in practice? (Look up some values of the deflection of the vertical in extreme cases, and estimate how much they affect directions).

1. Desribe the value drivers of the sheeter replacement decision?

1- Give information about the stages of concrete production. Discuss any two stages in detail.

y'(1+x^2)=(1/1-x)-3xy find the general solution.

Discuss briefly activated sludge age in terms of treated effluent quality.

Write a report showing the processes of the St Mary's wastewater treatment plant.

The report should include:

- General information about the plant (place, purpose, treatment capacity)

- Simplified flow diagram of the plant (showing only the important treatment processes)

- Functions of the each process (a few lines for each)

- Operational and maintenance issues of 2 processes in the plant

- References

Explain the different events that led to the entry of the United States into both the First World War (1914-1918) and the Second World War (1939-1945). Also pay attention to what specific role the US played in bringing these two wars to an end.

The City of Pomona (CA) has a population of 152,361. According to the data from 2017 to 2019, the average day demand in Pomona is 611 liters per capita per day (LCD). A new residential complex is being constructed in Pomona. There will be 16 three-story non-combustible apartment buildings, with an estimated total number of residents of 300 living in this apartment complex. Each building will have the same floor areas as follows: first floor, 1600 ft2 (square feet); second floor, 1400 ft2; third floor, 1200 ft2. The proximity and exposure between buildings can be considered average (use default). Using default peaking factors, please estimate the water demand for this new residential complex.

Indicate whether the following statements are true or false:

- Total stations cannot be used to find the difference in elevation between points. (      )

- In circular curves, the station of point of tangency PT is the station of point of intersection PI plus the tangent distance T. (        )

- In total stations, distance measurements are affected by temperature. (      )

- For a simple circular curve the lower the degree of curve the smaller is the radius. (      )

- Contour interval is the horizontal distance between two contour lines. (      )

You are a Structural Engineer working in a structural repair and rehabilitation consulting firm. You have been assigned to provide the answers and solutions for the following job: “Some cracks were observed on a suspended reinforced concrete slab on an existing public building. As these cracks raised public concerns, the owner has decided to carry out a structural investigation into the cause of cracking to check the structural integrity and determine the remedial works to be done.” (a) Outline and explain the process of investigation that would be recommended to identify the causes of the cracks.

(b) State Four (4) possible causes of the cracks?

(c) Propose Three (3) suitable tests to estimate the in-situ concrete strength.

(d) From the investigation, it was found that the cracks are due to structural overloading. Recommend a method to strengthen the existing slab and suggest a method to repair the crack.
