Discuss the effect of void ratio, particle size distribution,
and effective stress on soil behaviors (e.g., hydraulic
conductivity, deformation and strength) respectively.
when soil has undergone adequate drainage, the effective stress is
better then the total stress for determining potential failure or
settlement of the soil.
true or false
An organic soil, the void ratio e is found to be 10.0 and GS is .2.35 If this soil is fully saturated, find:a. Unit weight of the soilb. water conten w%c. Does this soil sink in water?
A sample of soil was tested; the results were
void ratio e = 1.024
moisture content w = 33.4%
specific gravity of solids Gs = 2.75
Using a phase diagram, determine the following:
a) The soil's bulk, dry and saturated unit weights, and degree of
saturation;
b) The volume of air void in 1m^3 of this soil; and
c) The weight of water required to fully saturate the 1m^3 soil

What is the importance of a Particle Size Distribution
Curve for Soils? What is it used for engineering wise? In addition,
explain fully the Uniformity Coefficient, the Coefficient of
Curvature, the Effective Size, D10, D30, D50, D60.
1) What will happen to the effective population size if
we change the sex ratio from 50% to 90% female? Genetic drift will
increase because
(A)The effective population size will increase
(B) The effective population size stay the same
(C) The effective population size will decrease
(D) The effective population size is unpredictable
2) Which stochastic factor(s) was resulting in the
prairie chicken population in Illinois heading towards extinction
before the translocation of more birds from outside the
state?

In this discussion, we'll discuss anxiety, effective and
ineffective interventions, and stress management. Please include
the following in your initial posting:
Describe a client from your clinical setting or work who
experienced severe anxiety or panic. Include a brief history and
three most pertinent medications.
Describe the assessment process for this patient.
Identify at least one effective and one non-effective nursing
intervention. Why did they work? What didn't work?
Name and describe two stress reduction techniques you have used
and...
