Photosynthetic Light Responses May Explain Vertical Distribution of Hymenophyllaceae Species in a Temperate Rainforest of Southern Chile
(Public Library Science, 2015)
Some epiphytic Hymenophyllaceae are restricted to lower parts of the host (<60 cm; 10-100 mu mol photons m(-2) s(-1)) in a secondary forest of Southern Chile; other species occupy the whole host height (>= 10 m; max PPFD ...

Comparison of intestinal response of chicks from light and heavy eggs to posthatch fasting
(2011-04-20)
The effects of posthatch fasting on villi height and number, crypt depth and number of globet cells in duodenum, jejunum and ileum of broiler chicks from heavy and light eggs were compared. The 2×3×3 factorial design (egg ...

Light fractionated ALA-PDT enhances therapeutic efficacy in vitro; The influence of PpIX concentration and illumination parameters
(Royal Society of Chemistry, 2013-02)
Light fractionation, with a long dark interval, significantly increases the response to ALA-PDT in pre-clinical models and in non-melanoma skin cancer. We investigated if this increase in efficacy can be replicated in PAM ...
Germination responses to light of four Neotropical forest tree species along an elevational gradient in the southern Central Andes
(Springer Tokyo, 2020-04)
Seed germination is a key part of plants´ life cycle and is mostly affected by thegenetic background, the environmental conditions experienced by the motherplant and the seedbed conditions. The germination response to light ...
Light sensitivity changes during dormancy induction in Polygonum aviculare L. seeds: development of a predictive model of annual changes in seed-bank light sensitivity in relation to soil temperature
(Wiley Blackwell Publishing, Inc, 2020-12)
Seeds of weed species require light to terminate dormancy and give way to germination. It is documented that sensitivity to light in Polygonum aviculare seeds increases during dormancy release. However, it is not known ...
Antimony glasses with large nonlinear refractive indices, small two-photon absorption coefficients and ultrafast response at telecom wavelengths
(2007-12-01)
Nonlinear (NL) optical properties of antimony oxide based glasses (AG) were characterized for excitation wavelengths from 800 to 1600 m. The NL refractive indices, n2, and the two-photon absorption (TPA) coefficient, β, ...
