Summary
A new integrative lighting score is needed to assess light
Area of Science:
- Chronobiology
- Lighting Science
- Human Health
Background:
- Human circadian clocks synchronize with the light-dark cycle.
- Disruption of circadian entrainment is linked to adverse health outcomes.
- Light influences non-visual functions like sleep, mood, and alertness.
Purpose of the Study:
- To address the need for a tool to assess light's impact on non-visual functions.
- To propose the development of an evidence-based integrative lighting score.
- To tailor lighting assessments to specific audiences and environments.
Main Methods:
- Reviewing compelling evidence from scientific literature.
- Outlining a plan for developing a lighting score using established metrics.
- Incorporating stakeholder and user feedback into the score's design.
Main Results:
- The need for a comprehensive assessment of light quality and quantity.
- The importance of including metadata on lighting environments and individual factors.
- The proposal of a weighting system combining light qualities with physiological effects.
Conclusions:
- An integrative lighting score can holistically assess lighting environments.
- Mathematical modeling can be used to generate an output score.
- The proposed system facilitates a unified assessment of all light sources.

02:16Light Acquisition
8.0K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

2.0K
Flame photometry, also known as flame emission spectrometry, is a technique used for the qualitative and quantitative analysis of elements present in a sample using a flame as the source of excitation energy. The concept of flame photometry was realized in the early 1860s by Kirchhoff and Bunsen, who discovered that specific elements emit characteristic radiation when excited in flames. The first instrument developed for this purpose was used to measure sodium (Na) in plant ash using a Bunsen...

01:26Introduction and Methods of Leveling
751
Leveling is a surveying procedure used to determine elevation differences between distant points. Elevation refers to the vertical distance above or below a reference datum, typically mean sea level (MSL). In the United States, elevations are often referenced to the mean sea level station at Father Point Rimouski along the St. Lawrence Seaway. To make the datum accessible, permanent markers are established throughout the region. These markers, called benchmarks, have known elevations. If the...
