In a soil investigation for a construction project, two soil types were identified with the following parameters (g = 9.81 m/s²):

Soil Type	Depth below ground level (m)	Unit weights (kN/m³)	Other parameters
Soil 1 (sand)	6.5	g = 17 and g_sat = 17.5	E =15000 kN/m²
Soil 2 (overconsolidated clay)	11.5	g_sat = 20	e₀=0.69, C_c=0.25, C_s=0.05

If the ground water level is at 2.5 m below the ground level, and the initial void ratio of the overconsolidated clay layer is 0.69, find the expected settlement in the clay layer only due to a proposed foundation that should imposes a pressure of 60 kN/m² on the mid-depth of the clay layer. The overconsolidation pressure is 125 kN/m². What is the the total settlement due to both the sand and clay layers (to the mid-height of the clay layer)?

two cylindrical specimens A and B of a soil were loaded as follows. Both specimen were isotropically loaded by a stress of 200 kpa under drained conditions. Subsequently, the radial stress applied on specimen A was held constant and the axial stress was incrementally increased to 440 kpa under undrained conditions. The axial stress on specimen B was held constant and the radial stress was incrementally reduced to 50 kpa under drained conditions. plot the total and effective stress paths...

I am doing a project on cancerous cell types and I've already identified 20 kinds, the tissues they effect, and the exact disease they cause. There are multiple other steps to the project that I am struggling with. This involves finding biochemicals (such as lipids, proteins, etc) associated with specific cancer cell types, the metabolic pathways they effect, membrane proteins (such as growth factors) and membrane protein transporters associated with the cancer cell type. Could someone give me an idea...
