Question 3: A soil profile consists of 6 m of coarse sand overlying 4 m of firm clay. The water table is at a depth of 2 m , and pore water pressures are hydrostatic over depth. The sand is estimated to have an average dry unit weight of

over its full thickness, and to be saturated below the water table and essentially dry above the water table. The clay has an average water content of

. The specific gravity of solids can be taken as 2.65 for both soils. Estimate the total vertical stress, pore water pressure, and effective vertical stress at a depth of 10 m .

Which statement is FALSE according to CPT guidelines for removal of cerumen?1) Office visit is for sinus infection and impacted cerumen removal. Physician can only charge for office visit because impacted cerumen removal is bundled into procedure/service of \( \mathrm{E} / \mathrm{M} \) code.2) Removal of impacted cerumen that requires instrumentation using a curette would be code 692103) Impacted removal of cerumen codes are unilateral codes and 50 modifier must be added if procedure is performed bilaterally4) Removal of impacted ear cerumen by irrigation is code 69209

In new product development, a "phases and gates" approach means that: [See p.56]

1) A firm's market is divided into specific segments (or "phases") linked by "gates" which allow synergies to be exploited

2) A firm's product development relies on time segments that must be linked through gates The process is divided into consecutive stages, at the end of each a decision is made as to whether to continue to the next stage of development The product is divided into separate modules where the interface between them are viewed as gates
