Ultraviolet radiation is considered the most damaging radiation to wood, affecting its properties and especially its color. The application of finishing products such as varnishes, stains and inks can minimize the action of this radiation.

Terrestrial ecosystems, increased solar ultraviolet radiation and interactions with other climatic change factors [PDF]
Based on research to date, we can state some expectations about terrestrial ecosystem response as several elements of global climate change develop in coming decades.

Relevance. One of the main components of the spectrum of sunlight is ultraviolet rays – invisible to the human eye short-wave radiation. The influence of these rays on plant life was considered insignificant until recently, but recent studies have shown ...

Ultraviolet Background Radiation
The results are reported of observations in narrow bands centered on 1115, 1425, and 1446 A of the flux from an empty high-galactic-latitude region and from several stars. The observations had been obtained with the aid of three ultraviolet-sensitive Geiger counters which were carried on an Aerobee-150 rocket launched from the White Sands missile ...

Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Ozone and ultraviolet radiation [PDF]
Imagine if the earth’s protective atmosphere did not exist and the earth was subjected to the harmful ultraviolet energy from the sun. Life as we know would not exist.

Apparent contradiction between negative effects of UV radiation and positive effects of sun exposure [PDF]
We would like to comment on the three contributions in the Journal of the National Cancer Institute, Vol. 97, No. 3, February 2, 2005: Kathleen M. Egan, Jeffrey A. Sosman, William J. Blot: Editorial: Sunlight and Reduced Risk of Cancer: Is the Real Story

Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...
