1Litterfall production and nutrient return in different-aged Chinese fir(Cunninghamia lanceolata) plantations in South China显示文摘The amounts of litter produced and nutrients returned play a fundamental role in the productivity and biogeochemical and nutrient cycling of forest ecosystems.We monitored annual litterfall production, nutrient return,and monthly dynamics over a one-year period in Chinese fir plantations aged 10, 22, and 34 years. Our objective was to quantify litterfall and nutrient return over a complete harvest rotation of Chinese fir. Annual litterfall production increased with stand age and was recorded as(3,294.6 ± 360.4),(3,733.9 ± 211.2), and(4,876.1 ± 212.8) kg ha-1a-1in stands aged 10, 22 and 34 years, respectively. Total litter production was significantly greater in the stand aged34 years than in the stand aged 10 years(p \ 0.05). With the exception of miscellaneous components, needle litterfall constituted the highest proportion(27.5–43.6 %), followed by branches/twigs(9.5–16.6 %). In all three plantations,annual total nutrient return to soil was in the order of C(1,119.95–2,709.05 kg ha-1a-1) [ N(39.32–62.04 kg ha-1a-1) [ K(15.95–22.44 kg ha-1a-1) [ P(1.30–1.63 kg ha-1a-1). C, N, K and P input to soil was significantly lower in the 10-year-old stand in comparison to the 22- and34-year-old stands(p \ 0.05). Litterfall production and nutrient return(C, N and K) followed similar patterns, and C and N input to soil was significantly related to litterfall production(needle, branch and total litterfall). C, N, P and K input to soil and total litterfall production were mainly driven by needle litterfall.Lili Zhou Addo-Danso Daniel Shalom Pengfei Wu Shubin Li Yayun Jia Xiangqing Ma 2015Journal of Forestry Research2015,26,1:32
2Biomass production,nutrient cycling and distribution in age-sequence Chinese fir(Cunninghamia lanceolate)plantations in subtropical China显示文摘Biomass production and nutrient(N, P, K, Ca and Mg) accumulation, distribution and cycling were quantified in young, mature and over-mature(10-, 22-, and34-year old) Chinese fir [Cunninghamia lanceolate(Lamb.) Hook] plantations in southern China. Total stand biomass of young, mature and over-mature stands was 38,104 and 138 t ha-1respectively. Biomass production increased significantly with age. Stem wood represented the highest percentage of stand biomass, accounting for 41,55 and 63 % in the young, mature and over-mature plantations respectively. Nutrients concentration was highest in live needles and branches, and lowest in stem wood. The plantations accumulated more N, followed by K, Ca, Mg,and P. Nutrient return amount, nutrient utilization efficiency, nutrient turnover time, the ratio of nutrient returnand uptake increased with stand age, which implies that young Chinese fir deplete soil nutrients to maintain growth,and efficiently utilize nutrients to decrease dependence on soil nutrients as they age. Harvesting young Chinese fir plantations would therefore lead to high nutrient loss, but prolonging the rotation length could improve soil recovery,and help sustain productivity in the long-term. Improved nutrient return through litterfall as stands get older may also be beneficial to nutrient pool recovery.Lili Zhou Addo-Danso Daniel Shalom Pengfei Wu Zongming He Chunhua Liu Xiangqing Ma 2016Journal of Forestry Research2016,27,2:13

4Non-thermal laser driven plasma-blocks for proton boron avalanche fusion as direct drive option显示文摘Fusion energy from protons reacting with ^(11) B,HB11,is extremely difficult or impossible when using thermal ignition by laser irradiation.This changes radically when using picosecond laser pulses with powers above petawatts dominated by nonlinear force driven ultrahigh ac-celeration of plasma blocks for a non-thermal initiation of igniting solid density HB11 fuel.For a cylindrical trapping of the reaction,laser produced ultrahigh magnetic fields above kiloTesla,have to be combined.The experimentally confirmed highly increased HB11 fusion gains due to avalanche reaction may lead to a scheme of an environmentally clean and economic power reactor.Heinrich Hora Shalom Eliezer Noaz Nissim Paraskevas Lalousis 2017Matter and Radiation at Extremes2017,2,4:2

9The promise of stem cell-based therapeutics in ophthalmology显示文摘The promising role of cellular therapies in the preservation and restoration of visual function has prompted intensive efforts to characterize embryonic, adult, and induced pluripotent stem cells for regenerative purposes. Three main approaches to the use of stem cells have been described: sustained drug delivery, immunomodulation, and differentiation into various ocular structures. Studies of the differentiation capacity of all three types of stem cells into epithelial, neural, glial and vascular phenotypes have reached proof-of-concept in culture, but the correction of vision is still in the early developmental stages, and the requirements for effective in vivo implementation are still unclear. We present an overview of some of the preclinical findings on stem-cell rescue and regeneration of the cornea and retina in acute injury and degenerative disorders.Israel Aharony Shalom Michowiz Nitza Goldenberg-Cohen 2017Neural Regeneration Research2017,12,2:2
