INVESTIGATION 3 INVERSE VARIATION
Determine How Magnetic Field Varies With Distance : 5
So only at a distance of about 16 mm does the magnetic field follow the inverse square law (exponent = -2). As the magnet gets farther way from the saw table, the exponent gets larger, and is about -2.5 at 18 mm. I "guessed" that if my testing device was sensitive enough, the exponent would approach -3, which would indicate inverse cube law.

Reading Mendelian randomisation studies: a guide, glossary
Jul 12, 2018Mendelian randomisation uses genetic variation as a natural experiment to investigate the causal relations between potentially modifiable risk factors and health outcomes in observational data. As with all epidemiological approaches, findings from Mendelian randomisation studies depend on specific assumptions. We provide explanations of the information typically reported in Mendelian
The Hall–Petch and inverse Hall–Petch relations and the
Nov 14, 2019We review some of the factors that influence the hardness of polycrystalline materials with grain sizes less than 1 µm. The fundamental physical mechanisms that govern the hardness of nanocrystalline materials are discussed. The recently proposed dislocation curvature model for grain size-dependent strengthening and the 60-year-old Hall–Petch relationship are compared. For grains less

This includes: clinical radiotherapy, combined modality treatment, experimental work in radiobiology, chemobiology, hyperthermia and tumour biology, as well as physical aspects relevant to oncology, particularly in the field of imaging
Comparison of the Mineral Content of Tap Water and Bottled
The variation in the mineral content among all North American tap water sources may therefore be even greater than in our study. Second, the levels of Ca 2+ , Mg 2+ , and Na + in tap water were obtained from municipal analysis reports, and levels of Ca 2+ , Mg 2+ , and Na +
Gene–environment interaction - Wikipedia
Gene–environment interaction (or genotype–environment interaction or GxE or G×E) is when two different genotypes respond to environmental variation in different ways. A norm of reaction is a graph that shows the relationship between genes and environmental factors when phenotypic differences are continuous. They can help illustrate GxE interactions. When the norm of reaction is not
Early-emerging and highly heritable sensitivity to human
Jun 03, 2021Bray et al. find that dogs’ sensitivity to human communication emerges early in development, prior to extensive socialization, and that over 40% of variation in point-following abilities and attention to human faces is attributable to genetic factors. These results suggest a robust developmental and genetic basis for these social skills in dogs.
