A controlled variable is one which the researcher holds constant (controls) during an experiment. It is also known as aconstant variableor simply as a "control." The control variable is not part of an experiment itself—it is neither theindependentnordependent variable—but it is important becau...
There was no significant difference in completion of the intervention between groups (p = 0.76, OR = 0.89, 95% CI [0.43 1.78]). The only demographic variable associated with completion rates was maternal education; higher maternal education correlated with higher completion rates across ...
In a randomized controlled trial, we tested the efficacy of Baby Triple P in a community sample of first-time parent couples. The intervention was develope
Many solid-dose oral drug products are engineered to release their active ingredients into the body at a certain rate. Techniques for measuring the dissolution or degradation of a drug product in vitro play a crucial role in predicting how a drug product
Node strength is the sum of outward and inward strength (also meaning that self-loops are included twice, in accordance with earlier publications) [2,36]. Closeness is defined as the inverse sum of the shortest distances to all other nodes, whereas the shortest distances are the sum of the...
Eq. (7) has the generic form of the exponential long time tail (1b) of the FPT distribution in a finite system. From Eq. (7) we identify the inverse of the characteristic time as . Moreover, Eq. (7) has an intuitive meaning: it demonstrates that first FPTs are exponentially unlikely...
with explanation of both technique and the significance of findings on history and physical examination, involved a number of real patients with physical signs, which gave repetition and possibly meaning and that students were able to view them at their own speed and also to review them at ...
