  2. Resting metabolic rate - Wikipedia

    en.wikipedia.org/wiki/Resting_metabolic_rate

    RMR differs from basal metabolic rate (BMR) because BMR measurements must meet total physiological equilibrium whereas RMR conditions of measurement can be altered and defined by the contextual limitations. Therefore, BMR is measured in the elusive "perfect" steady state, whereas RMR measurement is more accessible and thus, represents most, if ...

  3. Rock mass rating - Wikipedia

    en.wikipedia.org/wiki/Rock_mass_rating

    The rock mass rating (RMR) is a geomechanical classification system for rocks, developed by Z. T. Bieniawski between 1972 and 1973. [1] Since then it has undergone multiple modifications out of which, RMR89 [ 1 ] is commonly used.

  4. Rock mass classification - Wikipedia

    en.wikipedia.org/wiki/Rock_mass_classification

    Nowadays the classification system itself is not very often used, but the determination of the RQD as index for rock core quality is standard practice in any geotechnical rock drilling, and is used in many, more recent, rock mass classification systems, such as RMR and Q-system (see above). Rock Structure Rating (RSR)

  5. Core recovery parameters - Wikipedia

    en.wikipedia.org/wiki/Core_recovery_parameters

    RQD was originally introduced for use with core diameters of 54.7 mm (NX-size core). RQD has considerable value in estimating support of rock tunnels. RQD forms a basic element in some of the most used rock mass classification systems: Rock Mass Rating system (RMR) and Q-system. RQD is defined as the quotient:

  6. Perpendicular recording - Wikipedia

    en.wikipedia.org/wiki/Perpendicular_recording

    Perpendicular recording (or perpendicular magnetic recording, PMR), also known as conventional magnetic recording (CMR), is a technology for data recording on magnetic media, particularly hard disks. It was first proven advantageous in 1976 by Shun-ichi Iwasaki , then professor of the Tohoku University in Japan, and first commercially ...

  7. Mining rock mass rating - Wikipedia

    en.wikipedia.org/wiki/Mining_rock_mass_rating

    A rock mass with a high RMR before the adjustment factors are applied has a high reinforcement potential, and can be reinforced by, for example, rock bolts, whatever the MRMR value might be after excavation. Contrariwise, rock bolts are not a suitable reinforcement for a rock mass with a low RMR (i.e. has a low reinforcement potential).

  8. Slope mass rating - Wikipedia

    en.wikipedia.org/wiki/Slope_mass_rating

    Slope mass rating (SMR) is a rock mass classification scheme developed by Manuel Romana [1] [2] [3] to describe the strength of an individual rock outcrop or slope. The system is founded upon the more widely used RMR scheme, [4] which is modified with quantitative guidelines to the rate the influence of adverse joint orientations (e.g. joints dipping steeply out of the slope).

  9. Basal metabolic rate - Wikipedia

    en.wikipedia.org/wiki/Basal_metabolic_rate

    Resistance training if time is available is also helpful in post-exercise metabolism, but it is an adjunctive factor because the body needs to heal sufficiently between resistance training episodes, whereas the body can accept aerobic training every day. RMR and BMR are measurements of daily consumption of calories.
