Avian Research 2018年第3期9卷 253-263页

Background: The early stage of forest succession following disturbance is characterized by a shift in songbird composition as well as increased avian richness due to increased herbaceous growth in the forest understory. However, regeneration of woody species eventually outcompetes the herbaceous understory, subsequently shifting vegetation communities and decreasing availability of vital foraging and nesting cover for disturbance-dependent birds, ultimately resulting in their displacement. These early stages following forest disturbance, which are declining throughout the eastern United States, are ephemeral in nature and birds depend on such disturbances for nesting and other purposes throughout their ***: We investigated the use of a two-stage shelterwood method to manage long-term persistence of seven early successional songbirds over a 13-year period in an upland hardwood forest within the southern end of the m.d.umberland Plateau in the eastern United ***: Canopy and m.d.tory gaps created after initial harvest were quickly exploited by tree growth and canopy cover returned to these areas, accelerating the displacement of early-successional species. Woody stem.d.nsities increased substantially following stage two harvest as advanced tree regeneration combined with the re-opening of the overstory layer increased resource competition for early-successional plants in the understory. Carolina Wren(Thryothorus ludovicianus), Eastern Towhee(Pipilo erythrophthalmus), Indigo Bunting(Passerina cyanea), and Yellowbreasted Chat(Icteria virens) were characterized by imm.d.ate increases following initial harvest in 2001; while the American Goldfinch(Spinus tristis), Prairie Warbler(Setophaga discolor), and White-eyed Vireo(Vireo griseus) did not show an imm.d.ate response. Stage two harvest in 2011 rejuvenated vegetation which benefitted focal species, with six of seven species showing increases in densities between 2010 and ***: The two-stag

研究了从锌厂废渣（IPR）中回收锌和铅的方法。将Zn、Pb、Fe质量分数分别为11．3％、24．6％、8．3％的废渣，先用硫酸与渣混合并经焙烧、水浸及最后用NaCl溶液浸出。首先研究了焙烧的作用及浸出参数对回收锌的影响。将质量相等的H2SO4... 详细信息

研究了从锌厂废渣（IPR）中回收锌和铅的方法。将Zn、Pb、Fe质量分数分别为11．3％、24．6％、8．3％的废渣，先用硫酸与渣混合并经焙烧、水浸及最后用NaCl溶液浸出。首先研究了焙烧的作用及浸出参数对回收锌的影响。将质量相等的H2SO4／IPR在200℃下焙烧30min，随后对固体质量分数为20％的浆体在25℃下水浸6min，锌的回收率达86%。

Introduction:Alzheimer 's disease(Ad) is a common neurodegenerative disorder and the primary cause of dementia. Considerable evidence supports the “amyloid hypothesis,” stating that the pathogenesis of Ad is primarily caused by the deposition of amyloid-β(Aβ), which drives tau phosphorylation, neuroinflammation, and neurodegeneration in the brain. The amyloid hypothesis is strengthened by the significant and m.d.rate benefit of lecanemab, a humanized antibody through an anti-amyloid mechanism,showing slowed clinical decline(van dyck et al.,2023). The recent positive results of anti-amyloid trials have brought back focus on the amyloid hypothesis through biochemical, genetic, and pharmacological approaches(Zhang, 2023).

In 2008, a deep economic crisis started in the US and rapidly spread around the world. The financial and economic crisis, called “The Great Recession”, continues in many countries today and has been considered as the most severe recession in the history of US (after “The Great depression”). The crisis brought very fast growth in unemployment and it is foreseeable that it will be long lasting and that recovery will be very slow. Hence, such economic change obviously had a significant impact on workers worldwide.

Utilization of gene therapy approaches for cancertreatment requires either that the transferred genegains access to the great majority of the tumor cells orthat gene transfer results in a cytotoxic effect that willkill a large number of tumor cells that do not directlyreceive the gene of interest. The latter effect can beachieved by the transfer into tumors of
