How much carbon storage will loss in a desertification area?
Against this backdrop, the investigation of carbon storage loss in desertified regions becomes imperative for advancing global carbon neutrality and sustainable development. Gansu Province is situated in the northwest region of China, where land desertification and ecological fragility have persistently been the predominant
Effect of light, packaging condition and dark storage durations on
Colour loss was estimated by loss of redness (a*), a*/b*, nitrosomyoglobin, chroma (C); or increase of lightness (L*), MetMb, hue angle (H°). Colour loss was more dependent upon photochemical process than dark storage duration and packaging types. Lipid oxidation was not significantly affected by light exposure.

Coherently refreshed acoustic phonons for extended light storage
Coherently refreshed acoustic phonons for extended light storage. Acoustic waves can serve as memory for optical information, however, acoustic phonons in the GHz regime decay on the nanosecond timescale. Usually this is dominated by intrinsic acoustic loss due to inelastic scattering of the acoustic waves and thermal phonons.

The effects of different light storage conditions on volatile flavor
Apple is a photophilic fruit and the nutrients content such as phenolics loss is a major problem during fruit storage. Light can affect the yield, appearance and quality of apples. However, the molecular mechanism behind how white light induces phenolics accumulation to improve quality in fruits remains unclear.
Light Loss Factor (LLF) | Lighting
In the realm of lighting design, achieving optimal illumination is not just about selecting the right fixtures and bulbs; it also involves accounting for factors that can affect the longevity and efficiency of a lighting system. One crucial parameter in this regard is the Light Loss Factor (LLF). In this article, we delve into the definition and significance of LLF in

New World: What happens with First Light housing and storage
Those who own housing in First Light will be refunded the house''s cost but the tax paid so far will not be. This makes sense because the taxes weren''t paid for future usage after the invasion but rather the convenience and customisation up to that point. Any items that were in First Light storage will not be moved elsewhere.
Long light storage time in an optical fiber
Light storage in an optical fiber is an attractive component in quantum optical delay line technologies. Although silica-core optical fibers are excellent in transmitting broadband optical signals, it is challenging to tailor their dispersive property to slow down a light pulse or store it in the silica core for a long delay time.

Visible light exposure reduces the drip loss of fresh-cut watermelon
The drip loss ratio at each light intensity decreased with the storage time. The drip loss at 3000 Lux was 74.8 and 54.2% of that at 150 and 10 Lux, respectively, on the fifth day. Moreover, the drip loss ratio at 3000 Lux was also significantly lower than those at 10 and 150 Lux. Consequently, a stronger light exposure reduced the drip loss of

What is Light Loss Factor (LLF)
Light Loss Factor (LLF) is a term used to quantify the reduction in light output that occurs over time in a lighting system. It is an essential factor considered in lighting calculations to ensure that the desired level of illuminance is maintained throughout the lifespan of the system. LLF takes into account various factors that contribute to

Loss may be caused by changes of light, temperature, moisture, excessive respiration, infestation and, in some cases, the methods used to control infestation. In storage loss assessment, Quitco and Quindoza (1986) used the converted percentage damage method to obtain a rough indication of loss caused by insects.
