Turtlestitch is derived from educational programming languages such as Logo, Scratch and Snap! using the same jigsaw style programming paradigm [2] which offers simplicity suitable for novices but has powerful features, described as ‘low threshold, high ceiling’ by Seymour Papert. Its microworld is a turtle representing the needle of a ...
In pharmacology, the term ceiling effect refers to the property of increasing doses of a given medication to have progressively smaller incremental effect (an example of diminishing returns). Mixed agonist-antagonist opioids , such as nalbuphine , serve as a classic example of the ceiling effect; increasing the dose of a narcotic frequently ...
Low-threshold treatment programs are harm reduction-based health care centers targeted towards people who use substances. [1] " Low-threshold" programs are programs that make minimal demands on the patient, offering services without attempting to control their intake of drugs, and providing counselling only if requested.
The "ceiling effect" is one type of scale attenuation effect; [1] the other scale attenuation effect is the "floor effect". The ceiling effect is observed when an independent variable no longer has an effect on a dependent variable , or the level above which variance in an independent variable is no longer measurable.

Because axial fans are designed to blow air straight down at the floor, they can be used in ceiling and roof structures over 100 ft. tall. Because axial destratification fans can achieve destratification with low CFMs, it is imperative that the air leaving the nozzle achieve an air speed at the floor of between 0.2 and 0.5 m/s.
Low-threshold calcium spikes have been described in neurons from a variety of brain nuclei, including the thalamic relay, medial pontine reticular formation, lateral habenula, septum, deep cerebellar nuclei, CA1-CA3 of the hippocampus, association cortex, paraventricular and preoptic nuclei of the hypothalamus, dorsal raphe, globus pallidus ...

Threshold dose is the minimum dose of drug that triggers minimal detectable biological effect in an animal. [1] At extremely low doses, biological responses are absent for some of the drugs. The increase in dose above threshold dose induces an increase in the percentage of biological responses. [ 2 ]
