Dairy Food Science and Technology QUESTION #5990
Question 1
Fortification of milk with Vitamins A and D is most important for which type of milk?
  • Whole milk
  • Skim and low-fat milk, because fat-soluble vitamins A and D are removed with the fat during separation✔️
  • Flavored milk
  • UHT milk
Correct Answer Logic:
Fat-soluble vitamins A and D are naturally associated with the fat phase of milk. When fat is removed during skimming, these vitamins are also substantially removed. US FDA requires reduced-fat milks to be fortified with Vitamin A at \(\geq 2000\;\text{IU/quart}\) and Vitamin D at \(\geq 400\;\text{IU/quart}\).

Correct Answer Logic:
Substitute \(y=4-x\) into \(f=xy-2x\): \(f=x(4-x)-2x=4x-x^2-2x=-x^2+2x\). Maximizing: \(f'=-2x+2=0\Rightarrow x=1\), giving \(f(1,3)=-1+2=1\). This is a candidate for absolute extremum.

Geography QUESTION #1248
Question 3
Fossils are never found in:
  • Shale
  • Granite✔️
  • Sandstone
  • None of these
Correct Answer Logic:
Fossils are only found in sedimentary rocks (such as shale, sandstone, limestone) because they form from the gradual burial and compression of organic remains in sediments. Granite is an igneous rock formed from the cooling of magma at high temperatures and pressures — any organic material would be destroyed under such conditions. Therefore fossils are never found in granite or other igneous/metamorphic rocks.

Correct Answer Logic:
For a web plate with no transverse stiffeners (pure shear panel, \(a/h \to \infty\)), the shear buckling coefficient is \(k_v = 5.34\). When transverse stiffeners are present with aspect ratio \(a/h \leq 1\): \(k_v = 4.0 + \dfrac{5.34}{(a/h)^2}\). The critical shear stress is \(F_{cr} = \dfrac{k_v \pi^2 E}{12(1-\nu^2)(h/t_w)^2}\). AISC uses \(k_v = 5.34\) as the baseline for unstiffened webs.

Correct Answer Logic:
  • Molar mass of $NH_4SH = 51\text{ g/mol}$. Initial moles $= 5.1/51 = 0.1\text{ mol}$.
  • At equilibrium, moles of $NH_3 = H_2S = 0.1 \times 0.3 = 0.03\text{ mol}$.
  • Using $PV = nRT$: $P_{NH_3} = P_{H_2S} = \frac{0.03 \times 0.082 \times 600}{3} = 0.492\text{ atm}$.
  • $K_p = P_{NH_3} \times P_{H_2S} = (0.492)^2 \approx 0.242\text{ atm}^2$.

Nursing QUESTION #9252
Question 12
A patient with severe traumatic brain injury (TBI) is admitted to ICU. The nurse notes Cushing's Triad. Which set of signs is Cushing's Triad and what does it indicate?
  • Hypotension, tachycardia, and tachypnea — indicating neurogenic shock
  • Hypertension, bradycardia, and irregular respirations — indicating severely raised ICP✔️
  • Hypotension, bradycardia, and hypothermia — indicating neurogenic shock
  • Fever, hypertension, and diaphoresis — indicating autonomic dysreflexia
Correct Answer Logic:
Correct Answer: B — Cushing's Triad

Cushing's Triad is a late and ominous sign of severely raised intracranial pressure and impending brain herniation:
  1. Hypertension (widened pulse pressure) — body attempts to perfuse brain against rising ICP
  2. Bradycardia — reflex response (baroreceptor) to hypertension
  3. Irregular respirations — Cheyne-Stokes or ataxic breathing due to brainstem compression
This is a medical emergency. The nurse must:
  • Immediately notify the neurosurgeon and intensivist
  • Elevate HOB to \(30°\)
  • Administer Mannitol \(0.25 - 1 \text{ g/kg}\) IV or 3% NaCl
  • Prepare for emergency ICP monitoring or surgical decompression
  • Avoid hypotension (maintain CPP \(\geq 60 \text{ mmHg}\))
  • Avoid hyperthermia and hypoxia
Cushing's Triad represents the last compensatory mechanism before brain herniation — survival depends on seconds-to-minutes intervention.

Civil Procedure QUESTION #3689
Question 15
A plaintiff (State A) sues a defendant (State B) for $\text{\$80,000}$ in federal court. The defendant impleads a third-party (State A) for indemnity under Rule 14. The plaintiff then amends the complaint to assert a $\text{\$50,000}$ claim directly against the third-party defendant. Does the court have jurisdiction over the plaintiff's new claim?
  • Yes, under supplemental jurisdiction because it arises from the same nucleus of fact.
  • No, because 28 U.S.C. $\S 1367(b)$ bars supplemental jurisdiction for claims by plaintiffs against persons made parties under Rule 14 in diversity cases.✔️
  • Yes, because the total amount in controversy is now $\text{\$130,000}$.
  • No, because the claim against the third-party is for less than $\text{\$75,000}$.
Correct Answer Logic:
In cases founded solely on diversity, 28 U.S.C. $\S 1367(b)$ excludes supplemental jurisdiction over claims by plaintiffs against persons made parties under Rule 14 (impleader) if it would be inconsistent with the requirements of diversity jurisdiction (complete diversity).

Correct Answer Logic:

$\dfrac{\sin x-\cos x}{\sin x+\cos x} = \tan\!\left(x-\dfrac{\pi}{4}\right)$

So $f(x)=\tan^{-1}\!\left(\tan\!\left(x-\dfrac{\pi}{4}\right)\right)=x-\dfrac{\pi}{4}$ (within the principal range).

$\dfrac{df}{dx}=1$.

Let $g(x)=x/2$, so $dg/dx=1/2$.

Derivative of $f$ w.r.t. $g$: $\dfrac{df/dx}{dg/dx}=\dfrac{1}{1/2}=\mathbf{2}$
