Earthquake Iso‐Nuisance and Iso‐Damage Mapping for Alberta: Applications for Choosing Magnitude Thresholds to Manage Induced Seismicity

Earth's Future
We generate earthquake iso‐nuisance and iso‐damage maps for Alberta. These maps show the spatial distribution of earthquake magnitude required to reach a specific level of nuisance and damage, considering human exposure and surficial geological ...

Establishing a quality assurance baseline for radiological protection of patients undergoing diagnostic radiology

South African Journal of Radiology, 2011
Background. The wide use of ionising radiation in medical care has resulted in the largest man-made cause of radiation exposure. In recent years, diagnostic departments in Kenya have adapted the high-speed film/screen combination without well-established

Indole as a regulator of bacterial physiology

Mexican Journal of Medical Research ICSA, 2023
During the last years, indole has been the subject of study, this is chemically defined as an aromatic bicyclic heterocycle, from the synthesis of tryptophan after its degradation by tryptophanase (TnaA); in turn has been implicated as a signalling ...

Control for nuclear thermionic power source [PDF]

, 1978
A control for a power source which includes nuclear fuel interspersed with thermionic converters, is described. A power regulator maintains a substantially constant output voltage to a variable load, and a control circuit drives a neutron flux regulator ...

Dimensional Regularization and Dimensional Reduction in the Light Cone

, 2008
We calculate all the 2 to 2 scattering process in Yang-Mills theory in the Light Cone gauge, with the dimensional regulator as the UV regulator. The IR is regulated with a cutoff in $q^+$.

Comparative aspects in control strategies for hybrid DC-DC converters [PDF]

, 2016
Linear-switching hybrid DC/DC converters consist of a voltage linear regulator (classic NPN or nMOS topologies and LDO) connected in parallel with a switching DC/DC converter.

Noncommutative Geometry as a Regulator [PDF]

, 2000
We give a perturbative quantization of space-time $R^4$ in the case where the commutators $C^{{\mu}{\nu}}=[X^{\mu},X^{\nu}]$ of the underlying algebra generators are not central .

Prevalence and Trajectory of Household Material Hardship Among Children With Advanced Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Families of children with advanced cancer living in poverty experience inferior outcomes including poor parent mental health and worse child quality of life. Household material hardship (HMH: food, housing, transportation, and/or utility insecurity) is a modifiable poverty exposure—and potential intervention target—that ...

Effects of thidiazuron and methyl jasmonate tank mixes on cotton defoliation and the underlying phytohormonal mechanisms

Journal of Cotton Research
Background Thidiazuron (TDZ) is a widely used chemical defoliant in commercial cotton production and is often combined with the herbicide Diuron to form the commercial defoliant mixture known as TDZ·Diuron (T·D, 540 g·L-1 suspension).
