Increasing the response of PIN photodiodes to the ultraviolet [PDF]

, 1972
Solid state device uses sapphire windows and avoids coatings which absorb ultraviolet radiation and ultimately alter detector geometry. Ultimate solution for ultraviolet response is geometry with maximum peripheral area and horizontal field structure to ...

Cumulative solar ultraviolet radiation exposure and basal cell carcinoma of the skin in a nationwide US cohort using satellite and ground-based measures

Environmental Health, 2019
Background Basal cell carcinoma of the skin (BCC) is the most common cancer in populations of European ancestry. Although consistently linked with basal cell carcinoma of the skin in case-control studies, few prospective cohort studies have evaluated the

Genome-Wide Dynamic Evaluation of the UV-Induced DNA Damage Response

G3: Genes, Genomes, Genetics, 2020
Genetic screens in Saccharomyces cerevisiae have allowed for the identification of many genes as sensors or effectors of DNA damage, typically by comparing the fitness of genetic mutants in the presence or absence of DNA-damaging treatments.

Electromagnetic Radiation [PDF]

, 2010
Electromagnetic radiation, commonly referred to as light, underpins all spectroscopic techniques, ranging from the highly energetic gamma rays, through x-rays, ultraviolet, visible, infrared, microwaves to the low-energy radio waves.

Sensor detects hydrocarbon oil contaminants in fluid lines [PDF]

, 1966
Sensor with ultraviolet light monitors and detects hydrocarbon oil contaminants present in fluid lines. The light causes the oil particles to fluoresce. This light emitted by the oil particle is detected by a photocell which is relatively insensitive to ...

Habitable Zones and UV Habitable Zones around Host Stars

, 2010
Ultraviolet radiation is a double-edged sword to life. If it is too strong, the terrestrial biological systems will be damaged. And if it is too weak, the synthesis of many biochemical compounds can not go along.

The protection of Salicornia rubra from ultraviolet radiation by betacyanins and phenolic compounds

Plant-Environment Interactions, 2021
Salicornia rubra is a commonly occurring annual species of the salt playas of the Great Basin Desert of the western United States. In such habitats, plants experience high levels of ultraviolet radiation, which could potentially damage DNA.

Excess Ultraviolet Emission at High Galactic Latitudes: A New Horizons View

The Astronomical Journal
We present new observations of the cosmic ultraviolet background (CUVB) at high Galactic latitudes (∣ b ∣ > 40 ^∘ ), made using the Alice UV spectrograph on board the New Horizons spacecraft.

High-temperature-radiation analyzer [PDF]

, 1973
Six-channel radiometer with three ultraviolet detection channels measures temperatures at 2-millisecond intervals. One infrared channel measures total radiation, and two infrared channels measure radiation in discrete spectral intervals at rate of 40 ...

Experimental and numerical study on CuO/ZnO-modified aramid fabric for ballistic and UV radiation protection

Polymer Testing
Aramid fabrics are widely used in bulletproof armor because of their excellent mechanical properties. Previous studies have shown that ultraviolet radiation has a negative effect on the mechanical properties of aramid yarn, so improving the mechanical ...
