How do we deal with constant interrupting?

HADD - FAmily Support Group - ADHD and ADD
Children with ADHD are easily bored and highly impulsive. Often when they want to say something they have to tell you immediately. In these situations be firm but fair; for example, say: “Robin, I’m speaking to Laura now, and it will be your turn next.” Children with ADHD have difficulty waiting so if the interruption continues, ask the child to tell you in two or three words what they want to talk about. Its good to get them thinking in terms of key words or headlines.

What is the value of the Hubble constant?

Frequently Asked Questions in Cosmology
This is the question that professional astronomers ask the most frequently. For many decades the Sandage [Ho = 50] and de Vaucouleurs [Ho = 100] camps battled in a long lasting distance scale controversy. Many outsiders thought that the geometric mean of these values, Ho = 71 km/sec/Mpc, was a good compromise. The Sunyaev-Zeldovich effect has been used to determine Ho = 77 +/- 10 km/sec/Mpc.

What's the difference between the boundaryCondition and constant attributes on species?

SBML Frequently Asked Questions
Level 2 introduces the constant to the Species structure in addition to the boundaryCondition from Level 1. One might expect these attributes to both define that the species doesn't vary during simulation; however, there is a difference in their semantics. The constant attribute indicates that the species concentration doesn't vary during simulation no matter what reactions or rules it occurs in. Such a constant species can't have an associated rule.

Why were constant attributes introduced in SBML Level 2?

SBML Frequently Asked Questions
Given a model that doesn't contain algebraic rules it is possible to infer which components (species, compartment and parameters) are meant to be variables by examining the set of scalar rules, rate rules and reactions. However given a model containing algebraic rules knowledge of which symbols are variables and which are constants is required to solve the equations. The occurence of a symbol in an algebraic rule doesn't imply that the symbol is a variable.

What does the warning "constant conditional branch" mean?

HI-TECH Software Frequently Asked Questions
Typically this warning will only occur if the global optimizer is enabled and the index to a for() statement is auto. What happens with something like: for(i=0; i!=10; i++) whatever; Is that the global optimizer tracks the value of "i" after the expression "i=0". It then comes the expression checking to see if i is not equal to 10. The optimizer says, of course it is not equal to 10, you just set it to zero, and issues the warning.

What is Feigenbaum's constant?

FractSurf - FAQ
In a period doubling cascade, such as the logistic equation, consider the parameter values where period-doubling events occur (e.g. r[1]=3, r[2]=3.45, r[3]=3.54, r[4]=3.564...). Look at the ratio of distances between consecutive doubling parameter values; let delta[n] = (r[n+1]-r[n])/(r[n+2]-r[n+1]). Then the limit as n goes to infinity is Feigenbaum's (delta) constant. Based on independent computations by Jay Hill and Keith Briggs, it has the value 4.669201609102990671853..

Can the constant exposure to colds and other illnesses at school contribute to voice problems?

Voice Academy common questions
Can it ever! Close contact with kids who have upper respiratory infections is a hazard of the profession. Unfortunately, the common cold and sore throats usually involve your major voice-making organ (the larynx). When the membranes lining the vocal cords become infected or inflamed, you may note hoarseness, roughness and a lowering of pitch of the voice. Usually, these symptoms resolve when the virus has run its course.

Why create a humid environment with a constant relative humidity of 70%?

Cigar Smoker's FAQ
Cigars are naturally hydroscopic products. In common with many organic substances, they dry out in the absence of humidity in the air, or absorb moisture from the ambient air. They establish an equilibrium with the atmospheric humidity which surrounds them. a cigar will slowly dry out and loose essential oils. At 74% and higher, organic molecules will break down out-of-order, producing unwanted tastes. More importantly, at 80% or higher, you're leaving your stogies wide open to grow mold.

How hot do solar ovens get?

Solar Cooking Frequently-Asked Questions
Place an oven thermometer in the sunny part of the oven to get a reading similar to what the cooking pot is "feeling". The temperature reached by box cookers and panel cookers depends primarily on the number and size of the reflectors used. A single-reflector box cooker usually tops out at around 150? C (300? F) as the food approaches being done. High temperatures, however, are not needed for cooking. Your oven will cook just fine as long as it gets up to about 90? C (200? F) or so.

Can you sterilize water in a solar oven?

Solar Cooking Frequently-Asked Questions
Yes. In all three types, water can be brought to a boil. A little-known fact, however, is that to make water safe to drink, it only has to be pasteurized, not sterilized. Pasteurization takes place at 65? C (150? F) in only 20 minutes. This treatment kills all human disease pathogens, but doesn't waste the energy needed to bring the water to a boil.
