Oops, I meant "multilooped. It autocorrected it 0.o As in, circuits with multiple batteries. Can someone explain why the loop and current directions when using kirkhoffe's rules are arbitrary? Because if you choose the direction to be wrong, you'll simply end up with a negative current. Howeve...

Nope. Randomized Controlled Trial Study. What is the severity of disease that the agent causes to host? Actually, InfinityFlat was not really wrong. It is only an RCT if it is randomized and controlled, and you didn't say that it was. Technically studies that aren't RCTs are called quasi-experiment...

More more question... we just had our regional this past Saturday.... I noticed quite a few "tube-ulums". ( PVC tubes you play with flip-flops.) One of the rules states you have to be able to hold a note for at least 3 seconds. Pretty sure a tube-ulum can't do that. Should these be allowe...

It was Environmental Antecedent. A bit obscure, but I've seen it on a test before.

No, this one is a bit more obscure.

Mode of Transmission

The spectrum of circumstances that set the stage for illness or disease outbreak.

This was just someone pointed out to me last night - the only ones I'm aware of at the moment are for experimental design: the Conestoga 2012 and Wright State Invitational

Just FYI, some of the tests on the test exchange are still unavailable.

A human experiment?

Clinical Trial?

Is it Pathogenicity?

Yep

CulturallyScientific wrote:Thanks! That helps a lot!
Er.. for Q4: Prevalence ratio??

No problem.

No, not prevalence ratio. I just checked, the term is in the wiki (albeit with a less formal definition!), which means you should know it.

We got a legit shock value test for our regional competition. I'm so jealous of you guys with your hard tests

Bioassay? Hope so... Q 3: to compare people with and without exposures to see what happens to each. Yep! A3: Prospective cohort study. Q4: The proportion of persons infected, after exposure to a causative agent, who then develop clinical disease. For clinical vs. classical, this is the definition I...

Thanks for the scoresheets.

Hey so we all need vocal help for Disease Detectives right? So I'll post a definition and you'll reply with an answer and a new definition and it'll go on in time. OK let's start. -ongoing presence of an agent within a given area or population Endemic. Q2: an assessment of radioactive materials tha...
