We describe the first case of dicephalism in a caecilian larva, Ichthyophis bannanicus, from southeastern Guangxi, China. The two heads of the larva are united at the anterior one-third of the body. It is measured as： body mass 0.6 g, total length 42.4 mm, body width at middle 5.4 ram, head length 2.1 mm, head width 2.5 mm, snout length 1.5 mm, internarial distance 0.9 mm, and interorbital distance 1.7 ram. Compared to normal conspecific larvae, it is smaller except for the internarial distance, body mass and body width at midbody.

通过炫耀性消费理论视角,将《温德米尔夫人的扇子》剧中炫耀性消费行为置于维多利亚社会文化语境当中,阐释炫耀性消费的内在心理机制,并将视角从炫耀性消费拓展到其与社会资本建构以及上流社会身份焦虑之间的关联。通过对戏剧进行炫耀性消费解读发现,人们通过炫耀性消费所追求的精神意义只不过是一场虚幻,效仿者当以此为鉴,以免误入迷途。

[Objectives] In order to solve the problem of heavy metal pollution in paddy fields,field experiments were carried out to study the effect of Ca-Si soil conditioner on heavy metal remediation in paddy fields. [Methods] A conventional planting mode( CK) was used as the control,and a Ca-Si soil conditioner( Ca-Si) treatment was set to analyze the differences in soil pH and heavy metal contents in different treatments. [Results]The content of cadmium in the paddy field exceeded the soil pollution risk control value of agricultural land by 59. 33%. The Ca-Si soil conditioner increased the pH value of paddy field soil by 0. 58 unit. The fixation rates of Ca-Si soil conditioner on chromium,arsenic,cadmium and plumbum reached 75. 96%,14. 09%,18. 93% and 7. 81% compared with the CK,respectively,and the available cadmium and lead contents were reduced by 82. 35% and 80. 00%,respectively. [Conclusions]This study provides ideas and references for the remediation of heavy metal pollution in paddy soil.
