There is variation in timber test results due to species and wood temperature and from moisture content? The Internet site of Timber Queensland Limited "technical data sheet for correction factors for resistance moisture meters" lists correction factors for these effects. What are these?

Does timber always behave as a linear elastic material? What do you believe is a maximum safe working bending stress for F17 hardwood and MGP10 machine graded pine and why?
If you require higher load carrying capacity in timber what are your options?

As indicated in the following figure, an incompressible silty sand fill 16.4 ft thick was
placed on top of a 49.2 ft thick layer of soft and compressible silty clay. Underlying the
clay is a layer of incompressible sandy gravel. The soil properties of the silty clay layer are
given in the following figure. The ultimate settlement, Sult = 5.64 ft, from the primary
consolidation of silty clay layer due to the weight of the silty sand fill is calculated.

What type of Adsorbents you can use for In Situ Treatment of Wastewater in Mine Tailing Ponds?

Give 5 different names of chemicals that used as Adsorbents and small explanation on each with examples.

(Note: Firstly, the adsorbents sink in water and potentially be used to remove toxic pollutants at the bottom of tailing dams and then float after a certain time, so that the adsorbents can remove from water)

Is honey a cough remedy?

Does a teaspoon of honey before bed really calm a child’s cough? To test the folk remedy, pediatric researchers carried out a designed study involving a sample of 105 children who were ill with an upper respiratory tract infection.

On the first night, parents rated their children’s cough symptoms on a scale from 0 (no problems at all) to 30 (extremely severe). On the second night, the parents were instructed to give their sick child a dosage of liquid “medicine” prior to bedtime.

Unknown to the parents,
• a first group: are given a dose of honey.
• a second group: are given a similar dosage of dextromethorphan (DM), i.e., cough medicine.
• a third group (the control group) gave their sick children no dosage at all.

Again, the parents rated their children’s cough symptoms, and the improvement in total cough symptoms score was determined for each child. The data (improvement scores) for the study is given below:

Honey Dosage: 12 11 15 11 10 13 10 4 15 16 9 14
10 6 10 8 11 12 12 8 12 9 11 15

10 15 9 13 8 12 10 8 9 5 12

DM Dosage: 4 6 9 4 7 7 7 9 12 10 11 6
3 4 9 12 7 6 8 12 12 4 12 13
7 10 13 9 4 4 10 15 9

No Dosage (Control): 5 8 6 1 0 8 12 8 7 7 1

Do pumping tests represent aquifers heterogeneity?

A rigid strip footing with a width of B is constructed above the ground on a clay deposit, overlying bedrock. The depth of clay layer is H and the water level is at the natural surface. Before construction of the footing, laboratory tests on a saturated clay sample, taken at a depth of B/2 below the ground surface, provided the following properties:

Compression Index = Cc , Recompression Index = Cr , Consolidation Coefficient = cv

Over Consolidation Ratio = OCR, Water Content = w%, Specific Gravity = Gs

Assume the vertical uniform surcharge stress on the footing including the weight of footing and column = q

(a) Calculate the initial saturated unit weight of clay deposit.

(b) Based on the elastic theory (Boussinesq’s equation), calculate the excess pore water pressures at the depth of B/2 immediately after applying the surcharge load. Assume the vertical stress (q) is applied instantaneously.

(c) Using theory of 1-D consolidation, calculate the total average settlement of this rigid footing due to consolidation of the clay layer, long time after applying the total load.

(d) Determine the average settlement of this rigid footing after n days of applying the total load due to consolidation of clay deposit.

You have been asked to acceleration the schedule on the project and to minimize the cost impact. Address the options noted below and discuss the pros and the cons for each.

a. Fast-tracking

b. Adjusting leads and lags on connected activities. Remember a lag means starting an activity before the successor has been completed.

c. Adding resources

d. Resource leveling

e. Crashing f. Use of alternate work calendars/schedules

The settlement of foundations is typically the result of three separate occurrences that take place in the soil which provides support. List these factors and give a brief description of each.

Explain the difference between soil compression, soil consolidation, and compaction. Explain the difference between a normally consolidate and an over-consolidated soil deposit.
