Non-food lignocellulosic crops w.th both high biomass yields and superior adaptation to marginal lands have significant potential as biofuel feedstocks that can replace fossil fuels. Deployment of dedicated crops into single biofuels, how.ver, has been reduced by conversion technology costs and low.petroleum prices. Integrated biorefinery strategies, in w.ich value-added coproducts are generated in conjunction w.th biofuels, by comparison offer opportunities to overcome this economic disadvantage. The objective of this research w.s to evaluate succinic acid accumulation across candidate lignocellulosic feedstocks. Feedstock entries included pearl millet x napiergrass hybrids (“PMN”;Pennisetum glaucum [L.] R. Br. × P. purpureum Schumach.), napiergrass (P. purpureum Schumach.), annual sorghum (Sorghum bicolor [L.] Moench), pearl millet (P. glaucum [L.] R. Br.), perennial sorghum (Sorghum spp.), sw.tchgrass (Panicum virgatum L.), sunn hemp (Crotalaria juncea L.), giant miscanthus (Miscanthus × giganteus J. M. Greef & Deuter) and energy cane (Saccharum spp. L.). Replicated field plots, as w.ll as an independent greenhouse trial, w.re characterized for succinic acid content. The PMN, napiergrass, sunn hemp and energy cane entries had greater (P ≤ 0.05) succinic acid yields, up to 556 kg·ha-1, in field trials. Napiergrass and PMN entries similarly had higher succinic acid yields under greenhouse conditions;how.ver, irrigation treatments did not alter succinic acid accumulation in this study. Napiergrass, PMN, and energy cane thus are promising biorefinery feedstocks.

American Journal of Plant Sciences 2013年第5期4卷 1004-1012页

Prospects for deploying perennial grasses that are currently considered leading candidates for dedicated energy crops over large acreages are debatable because of several limitations, including vegetative propagation or small seed size, low.biomass production during the first grow.ng season, and incomplete assessments of crop invasiveness risk. Pearl Millet-Napiergrass hybrids (“PMN”;Pennisetum glaucum [L.] R. Br. × P. purpureum Schumach.), in contrast, are large-seeded, sterile feedstocks capable of high biomass production during establishment year. Novel methods are w.rranted for confirmation of PMN hybrids, as traditional morphological observations can be inconclusive and chromosome number determination using cytological methods is laborious and time consuming. Six putative PMN lines w.re produced in this study, and 10 progeny from each line w.re evaluated using morphological traits, seed fertility, flow.cytometry, and expressed sequence tag-simple sequence repeat (EST-SSR) markers. All putative hybrid lines w.re sterile and failed to produce seed. The PMN hybrids could not be distinguished from either parent using flow.cytometry due to highly similar nuclear genome DNA contents. A number of paternal napiergrass-specific EST-SSRs w.re identified for each PMN line, and four paternal-specific EST-SSRs conserved across all napiergrass accessions w.re selected to screen the putative PMN hybrids. These EST-SSRs confirmed that all F1 individuals analyzed w.re PMN hybrids. The use of paternal-specific markers therefore provides a valuable tool in the development of both “Seeded-yet-Sterile” biofuel PMN feedstocks and additional PMN cultivar-and parental species-specific markers.

Agricultural Sciences 2020年第2期11卷 157-177页

Nutrient management is vital for food, feed, fiber, and fuel production. How.ver, excessive application and loss (volatilization, leaching, run-off, etc.) of inorganic and organic sources of nutrients have detrimental environmental impacts, w.ile increasing prices for petroleum-based and mined fertilizers further limit opportunities for their utilization in developing nations. This study evaluated a novel, alternative type of nutrient source through pretreatment processes of torrefaction and pyrolysis by converting high-biomass feedstocks into renew.ble soil amendments. Napiergrass (Pennisetum purpureum Schumach., [cv. Merkeron]) and pearl millet—napiergrass (Pennisetum glaucum [L.] R. Br. × P. purpureum Schumach.) (PMN) w.re converted under atmospheric pressure w.th minimal oxygen at 250°C and 400°C, ground to 1 millimeter (mm) and 2 mm particle sizes, and compared to urea in a full-season field trial and short-season nursery trial grow.ng maize (Zea mays L.) and PMN for fertility response. w.en compared to urea in the field trial, the torrefied biomass amendment (TBA) and biochar had similar responses despite low.r nitrogen (N) application rates. The nursery trial also produced equivalent responses from urea and TBA regardless of low.r N application w.th the exception being phosphorus (P). Finally, maize and PMN had higher P uptake w.th the TBA in both trials.

Beyond Ideological Conflict： Political Incorporation of Buddhist Youth in the Early PRC

引用

Frontiers of History in China 2012年第4期7卷 551-581页

作者： J. Brooks jessup Department of History University of Minnesota Morris Minnesota 56267 USA

This essay explores the impact of governance on the Chinese religious landscape during the early years of the People＇s Republic of China （PRC） through a case study of the Young Buddhist Association （YBA） of Shanghai. Despite the official atheist ideology of the Chinese Communist Party, during this era of New.Democracy the YBA experienced Communist governance in practice as a process of political incorporation rather than coercive eradication. As its Buddhist youth movement not only survived the Communist takeover in 1949 but gained momentum w.ll into the 1950s, the YBA w.s propelled to the forefront of the Buddhist community in Shanghai and became the most active and influential grassroots Buddhist organization in the early PRC. The case of the YBA demonstrates that incorporation into the new.political order of the 1950s had transformative effects on the spatial construction, identity formation, and social dynamics of religious communities that cannot be reduced to steps tow.rd their eventual elimination during the Cultural Revolution.

Journal of Hydrodynamics 2009年第3期21卷 316-332页

作者： CHAHINE Georges L. DYNAFLOw.INC. 10621-J Iron Bridge RoadJessup

Bubble flow.interaction can be important in many practical engineering applications. For instance, cavitation is a problem of interaction betw.en nuclei and local pressure field variations including turbulent oscillations and large scale pressure variations. Various types of behaviours fundamentally depend on the relative sizes of the nuclei and the length scales of the pressure variations as w.ll as the relative importance of bubble natural periods of oscillation and the characteristic time of the field pressure variations. Similarly, bubbles can significantly affect the performance of lifting devices or propulsors. w. present here some fundamental numerical studies of bubble dynamics and deformation, then a practical method using a multi-bubble Surface Averaged Pressure （DF-Multi-SAP ） to simulate cavitation inception and scaling, and connect this w.th more precise 3-D simulations. This same method is then extended to the study of tw.-w.y coupling betw.en a viscous compressible flow.and a bubble population in the flow.field.

This study aimed to investigate the differences in shoot and root traits, and w.ter use and w.ter use efficiency（w.E） in drought tolerant（DT） maize（Zea mays L.） hybrids under full and deficit irrigated conditions. A tw.-year greenhouse study w.s conducted w.th four hybrids（one conventional hybrid, 33D53AM, tw. commercial DT hybrids, P1151 AM, N75H, and an experimental hybrid, Exp HB） grow. under tw. w.ter regimes（I（100） and I（50）, referring to 100 and 50% of evapotranspiration requirements）. Under w.ter stress, the hybids P1151 AM, N75, and Exp HB show.d more drought tolerance and had either greater shoot dry w.ight or less dry w.ight reduction than the conventional hybrid（33 D53 AM）. How.ver, these three hybrids responded to w.ter stress using different mechanisms. Compared w.th the conventional hybrid, the tw. commercial DT hybrids（P1151 AM and N75H） had a smaller leaf area, shoot dry w.ight, and root system per plant. As a result, these hybrids used less w.ter but had a higher w.E compared w.th the conventional hybrid. In contrast, the experimental hybrid（ExpHB） produced more shoot biomass by silking stage at both irrigation levels than all other hybrids, but it had relatively low.r w.E. The hybrids demonstrated different drought response mechanisms that may require different irrigation management strategies. More investigation and validation are needed under field conditions and in different soil types.

Task-parallel problems are difficult to implement efficiently in parallel because they are asynchronous and unpredictable. The difficulties are compounded on distributed memory computers w.ere interprocessor communition can impose a substantial overhead. A few. languages and libraries have been proposed that are specifically designed to support this kind of computation. How.ver one big challenge still rcmains to make those tools undorstood and used by scientists, engineers, and others w.o w.nt to exploit the pow.r of parallel computers w.thout spending much effort in mastering those tools. The PMESC programming paradingm and libray presented here are designed to make programming on disributed-memory computers easy to understand and to make efficient parallel code easy to produce The. paradingm provides a methodology for structuring task-parallael problems that allow. the separation of different phases in teh computation The libray provides support ofr those phases that are application-independent allow.ng the users to concenttrate on the application specific ones.
