HR strategic initiatives of employee and labor relations
Analyze HR strategic initiatives of employee and labor relations that positively impact organizational effectiveness. The three critical elements focus on employee discipline, performance management, and employee and labor relations.
Structure and function of hemoglobin
In addition to O2, another diatomic molecule that can bind to the iron atom in hemoglobin is CO. Explain in biochemical terms why high levels of CO gas are lethal and site a specific example of accidental death by CO poisoning (where, when, how)
Functional classes of proteins
For each of the five major protein types in eukaryotic cells
1. Provide a specific example of a protein in each class
2. Describe its primary function
3. Identify cellular locations where you would find this specific protein (Nucleus, cytosol, membranes)
Peptides and X-ray/NMR Methods
Describe one advantage and one disadvantage of trying to solve molecular protein structures by:
1. X-ray crystallography
2. Nuclear Magnetic Resonance (NMR) Spectroscopy
Protein Purification Methods
What chemical properties of sodium dodecyl sulfate (SDS) contribute to equal charge/mass ratios needed for molecular mass determinations using SDS page? Why is the protein solution heat denatured prior to gel loading?

Air Flow Dynamics
Q.No.1
Briefly explains the function of any ten (10) duct work components with suitable
diagram.
Q.No.2
Water is pumped from a chiller in the basement, where Z1 = 0 m, to a cooling coil
located on the twentieth floor of building, where Z2 = 100 m. What is the
minimum pressure rise the pump must be capable of providing if the temperature
of the water is 4 °C?
Q.No.3
Compute the pressure drop in 30 m of straight circular sheet-metal duct 300 mm in
diameter when the flow rate of 20 °C air is 0.75 m3
/s.
Q.No.4
An airflow rate of 2 m3/s passes through a rectangular duct 0.3 by 0.5 m. Calculate
the pressure drop in 45 m of straight duct using (a) D eq and (b) D eq, f.
Q.No.5
Briefly explain the function of radial, forward curved and backward inclined fans.
Q.No.6
Design the duct system (find duct diameter) using a Velocity reduction method.
Use Velocity of air 8 m/s in main duct (Segment A), 5 m/s in downstream and
branches, and draw the duct system by using Visio tool.
Calculate the energy required to produce 7.00 mol Cl2O based on the following balanced equation. 2Cl2 (g) + 7O (g) + 130 kcal 🡪 2Cl2O (g)
