1Influence of alumina on mineralogy and environmental properties of zinc-copper smelting slags显示文摘An iron-silicate slag, from a zinc-copper smelting process, and mixtures of this slag with 5wt%, 10wt%, and 15wt% alumina addition were re-melted, semi-rapidly solidified, and characterized using scanning electron microscopy equipped with energy dispersive spectroscopy, and X-ray diffraction. The FactSage TM 6.2 thermodynamic package was applied to compare the stable phases at equilibrium conditions with experimental characterization. A standard European leaching test was also carried out for all samples to investigate the changes in leaching behaviour because of the addition of alumina. Results show that the commonly reported phases for slags from copper and zinc production processes (olivine, pyroxene, and spinel) are the major constituents of the current samples. A correlation can be seen between mineralogical characteristics and leaching behaviours. The sample with 10wt% alumina addition, which contains high amounts of spinels and lower amounts of the other soluble phases, shows the lowest leachabilities for most of the elements.Sina Mostaghel Caisa Samuelsson Bo Bjrkman 2013International Journal of Minerals,Metallurgy and Materials2013,20,3:4
250MW级SGT-800型西门子燃气轮机的性能验证显示文摘SGT-800是西门子工业透平公司制造的功率最大的工业燃气轮机。2010年推出SGT-800增强型,其额定功率为50.5 MW。为保证产品的质量,对此增强型燃气轮机进行了细致的实验验证,包括零部件级和整机级的验证工作。零部件级试验主要包括第1级静叶和第1级动叶的热动力学性能的验证工作。整机试验包括测试燃气轮机综合性能、压气机性能与转子动态性能、燃烧室的稳定性/排放/热状态、透平性能及其热状态等。测试结果表明,其性能圆满地达到了预期水平。截止2014年4月,首台增强型燃气轮机商业运行的累计等效运行小时数(EOH)已经超过24 000 h。在20 000等效运行小时数之后计划进行的开机检查结果表明,所有部件的状态均达到或预期达到设计寿命。王列科 Daniel Lrstad Sven Axelsson Mats Bjrkman 2014燃气轮机技术2014,27,4:3

12From landrace to modern hybrid broccoli:the genomic and morphological domestication syndrome within a diverse B.oleracea collection显示文摘Worldwide,broccoli(Brassica oleracea var.italica)is among the most economically important,nutritionally rich,and widely-grown vegetable crops.To explore the genomic basis of the dramatic changes in broccoli morphology in the last century,we evaluated 109 broccoli or broccoli/cauliflower intermediates for 24 horticultural traits.Genotype-bysequencing markers were used to determine four subpopulations within italica:Calabrese broccoli landraces and hybrids,sprouting broccoli,and violet cauliflower,and to evaluate between and within group relatedness and diversity.While overall horticultural quality and harvest index of improved hybrid broccoli germplasm has increased by year of cultivar release,this improvement has been accompanied by a considerable reduction in allelic diversity when compared to the larger pool of germplasm.Two landraces are the most likely founding source of modern broccoli hybrids,and within these modern hybrids,we identified 13 reduction-in-diversity genomic regions,53 selective sweeps,and 30(>1 Mbp)runs of homozygosity.Landrace accessions collected in southern Italy contained 4.8-fold greater unique alleles per accessions compared to modern hybrids and provide a valuable resource in subsequent improvement efforts.This work broadens the understanding of broccoli germplasm,informs conservation efforts,and enables breeding for complex quality traits and regionally adapted cultivars.Zachary Stansell Thomas Björkman 2020Horticulture Research2020,7,1:1
