A simply supported beam with a span of 26 FT is used to carry a service dead load (including self-weight) of 1.65 KLF and a service live load of 3.3 KLF and is reinforced with 4-#9 bars. The beam has a width b of 14 IN, an effective depth of 24.5 IN., and a height of 27 IN. The material strengths are f’c = 4000 PSI and fy = 60 KSI. The immediate deflection due to live load is limited to L/360. Does the beam meet these limits?

A city is considering a reservoir water as its new drinking water source. As a result, the city council wants to know how good the reservoir water is to serve this potential purpose. Assume you are the chief engineer of the city utilities; please provide a list of water quality parameters need to be tested and the corresponding testing methods.

Assuming a cost of AED 1.5/Liter to pump and distribute water in a municipal supply system that loses (P) of its water because of leaks, how much money is wasted annually for a city of (X) million people with a per capita demand of 300 Liters/day?

where, X = 21.0 millions P = 2%

The inactivation of a pathogenic bacterium by HOCl follows Chick’s law, i.e. the rate of death is a 1^st order reaction, where the death rate is proportional to the number of bacteria at any time. 90 % of the pathogen are killed after 5 min for a constant free chlorine concentration of 2 mg/L (assume low pH, where all free chlorine is present as HOCl).

a)      (9%) What is the percent kill after 10 min at the same HOCl concentration?

b)     (8%) What percentage of the free chlorine would be present as HOCl (not OCl^-) at pH8 if the pK_a for hypochlorous acid is 7.5?

c)       (3%) Why and how would the disinfection time have to change to still achieve 90 % kill of the pathogen at pH 8 at the same free chlorine concentration? (no need to calculate, discuss in terms of order of magnitude)

Within a study watershed there are six precipitation gauges with the following average annual rainfall [mm] at the following elevations [m]:

GaugeElevations = [442, 548, 736, 770, 852, 1031]

GaugePrecipitation = [1392, 1246, 1495, 1698, 1717, 1752]

Topographic analysis of this watershed gives the following distribution of its area with elevation:

AreaElevations = [200, 400, 600, 800, 1000, 1200, 1400, 1600]

AreaFraction = [0.0, 0.028, 0.159, 0.341, 0.271, 0.151, 0.042, 0.008]

Where the AreaElevations are the upper end of that area's elevation range. For example, 2.8%, of the basins area has an average elevation of 300m (i.e. between 200m and 400m). Given this information, estimate the average annual precipitation that this watershed receives.

An equal-tangent crest vertical curve connects an initial grade of +2.5% and a final grade of –0.5%. The curve is designed for 70 mi/h and the station of the PVT is 132+62 and is at elevation 833 ft. What is the station and elevation of the curve's high point?

A trapezoidal wall 2.75m in height has a bottom width 5m and upper width 4.5m. Determine quantity of cement and sand of mortar for CHB Laying using class A mixture for 10x20x40CHB

Guardian Ad Litem

Purpose: To become acquainted with court-appointed advocates for children (minors) and vulnerable adults (mentally disabled, elderly, etc.)

Outcome: You will demonstrate a working knowledge of basic family law procedures.

What is a Guardian Ad Litem?

A Guardian Ad Litem is a court appointed official (usually an attorney) who represents an individual that cannot legally defend or represent himself/herself in a legal action. This could be a lawsuit, family law issue, settlement negotiation and, in some cases, inheritance issues.

Children under 18 years of age, adults with dementia, mentally challenged individuals, etc. are all considered vulnerable by the court. So, during a nasty custody battle a Guardian Ad Litem (GAL) is appointed to represent the child.    If there is more than one minor child in a family law issue then each child is appointed their own GAL to represent them. The GAL will make home visits, talk to the child, family friends, etc. and be a part of any settlement negotiation. The Judge will always ask the GAL for a report. The GAL's main goal is to represent the child and settle issues in the child's best interest. The parents have little or no say in the matter. In family law matters, it was usually their bickering and inability to resolve issues involving their children that required the appointment of the GAL in the first place.

GAL's also investigate issues of child abuse, when one parent is accusing the other, to see if there is any validity to the claims. Sometimes parents just accuse the other of horrendous acts just so they get custody and child support. The children are the silent victims in these cases and the GAL's are there for the children.

GAL's are not only appointed in family law issues. Years ago, my children were a part of a personal injury lawsuit and each of them had a GAL appointed to them to be a part of the monetary settlement negotiations. They also had a say in where and how the settlement would be placed and when it could be given to them (at age 18 or later). Parents do not have any legal right to a child's settlement money and the laws were changed to enforce that issue years ago.

Assignment:

I want you to research how to find a Guardian Ad Litem in King County and in a two to three paragraph paper tell me how you find one, what are the requirements and when would one be necessary.

Primary clarifier effluent was analyzed for solids content by an analytical laboratory. A 250-mL sample of the effluent was filtered through a laboratory (1 micrometer) filter. A 241-mL sample of the filtrate contained 89 mg of salts as dissolved solids (Residue 1). Solid residue from the filtration was dried overnight at 105 deg C and weighed 37 mg (Residue 2). What were the concentrations of total dissolved solids, total suspended solids, and total solids in the primary clarifier effluent?
