QTL analysis of flag leaf in barley （Hordeum vulgate L.） for morphological traits and chlorophyll content

To understand genetic patterns of the morphological and physiological traits in flag leaf of barley, a double haploid （DH） population derived from the parents Yerong and Franklin was used to determine quantitative trait loci （QTL） controlling length, width, length/width, and chlorophyll content of flag leaves. A total of 9 QTLs showing significantly additive effect were detected in 8 intervals on 5 chromosomes. The variation of individual QTL ranged from 1.9% to 20.2%. For chlorophyll content expressed as SPAD value, 4 QTLs were identified on chromosomes 2H, 3H and 6H; for leaf length and width, 2 QTLs located on chromosomes 5H and 7H, and 2 QTLs located on chromosome 5H were detected; and for length/width, I QTL was detected on chromosome 7H. The identification of these QTLs associated with the properties of flag leaf is useful for barley improvement in breeding programs.     

张爱玲的间接诉情文本解读

《红楼梦魇》是张爱玲情节化操作之外的特例,这部关于《红楼梦》的考据和评点专论,是她穷毕十年精力的后期作品。张爱玲对《红楼梦》及研究的“疯狂”,是其这部学术专论的表征;而她与《红楼梦》及其作者之间的文化传承关系,是这部专论的非学术隐义。张爱玲与曹雪芹文人品格的共性,源于他们共同的末世之感;张爱玲继承了《红楼梦》对悲剧本原的演绎方式,将《红楼梦魇》作为自己的间接诉情文本。     

The possible contribution of a mantle-derived fluid to the Ningwu porphyry iron deposits-Evidence from carbon and strontium isotopes of apatites

Apatite is a characteristic mineral for the iron deposits in the Ningwu region. Apatite shows a range of δ¹³CPDB values from -9.6 ‰ to -0.6‰, and most of them with the δ¹³CPDB values distributed in a range of mantle carbon (i.e., ﹣2‰ to -9‰) except for samples T-06-1and J-06-3. Apatites in the Ningwu porphyry iron deposits yield a narrow variation range of ⁸⁷Sr/⁸⁶Sr values from 0.706326 to 0.707577, similar to those of the volcanic and subvolcanic rocks and lower than those of a typical mantle-derived magmatic apatite (i.e., about 0.7040), indicating that formation of the apatites were involved with crust material contamination. Δ¹³CPDB and ⁸⁷Sr/⁸⁶Sr values of the apatite indicate a possible contribution of mantle-derived fluid and material to formation of the Ningwu porphyry iron deposits, supported by regional geology, regional gravities and geochemistry of the volcanic and subvolcanic rocks in the Ningwu region.

Apatite is a characteristic mineral for the iron deposits in the Ningwu region. Apatite shows a range of δ^13CPDB values from -9.6‰ to -0.6‰, and most of them with the δ^13CPDB values distributed in a range of mantle carbon （i.e., -2‰to -9‰）, except for samples T-06-1 and J-06-3. Apatites in the Ningwu porphyry iron deposits yield a narrow variation range of ^87Sr/^86Sr values from 0.706326 to 0.707577, similar to those of the volcanic and subvolcanic rocks and higher than that of a typical mantle-derived magmatic apatite （i.e., about 0.7040）, indicating that formation of the apatites was involved with crust material contamination.δ^13CPDBand ^87Sr/^86Sr values of the apatite indicate a possible contribution of mantle-derived fluid and material to formation of the Ningwu porphyry iron deposits, supported by regional geology, regional gravities and geochemistry of the volcanic and subvolcanic rocks in the Ningwu region.

半鞅积分方程解的存在唯一性

本文在严加安［１］的基础上，讨论半鞅积分方程 Ｘ＝Φ（Ｘ）＋Ｆ（Ｘ）．Ｍ解的存在唯一性．我们所获得的存在唯一性定理，与［１］中定理１３．１３相比较，不要求Ｆ、Φ满足Ｌｉｐｓｃｈｉｔｚ连续条件，而仅要求它们满足局部Ｌｉｐｓｃｈｉｔｚ连续条件，但我们附加了所谓的增长条件．我们还给出解过程估计式．此外，还给出Ｄｏｌｅａｎｓ－Ｄａｄｅ方程解的另一存在唯一性定理。
