The reaction between sodium trifluoromethanesulfinate, which was prepared from trifluorome- thyl bromide, with bromine in aqueous solution resulted in the formation of trifluoromethanesulfonyl bromide (CF_3SO_2Br). CF_3SO_2Br reacted with alkenes and alkyne to give the corresponding adducts with the loss of SO_2 in good yields, and with compounds containing active hydrogen to give brominated derivatives. A radical reaction mechanism was proposed and confirmed by EPR study.

The sequences of the mitochondrial 16S rRNA gene of 16 Oedipodidae species were amplified and sequenced. All sequences were aligned and analyzed and the phylogenetic relationships were inferred. The properties of 16S gene in Oedipodidae showed typical patterns of many insects such as a high A＋T content and variable distance-dependent transition/transversion ratios. The 0.2 weight for sites of loops may be advisable for phylogeny reconstruction using the maximum parsimony method. The phylogenetic analysis results do not support the current subfamily classification systems of Oedipodidae. Bryodemellinae and Bryodeminae are closely related and should be merged as one subfamily. The status of Oedipodinae and Locustinae is also problematic.

黔南州是贵州省主要产粮地区之一,多措并举保障粮食安全生产对推动贵州农业现代化高质量发展具有重要意义。本文从种植面积、产量、受灾情况分析2022年粮食生产形势,从“双保”“双扩”“双藏”“双化”方面总结黔南州保障粮食生产工作措施及成效。指明其中生产基础薄弱、组织化程度低、链条延伸不足问题,提出了多措并举调动种粮积极性、持续深入开展“非粮化”排查整治、强化基础设施建设、推进种业振兴行动上求“新跃升”、加快推进粮油产业化等提升建议。

Cadmium （Cd） is a toxic heavy metal that has no known biological functions except in some marine diatoms, such as Thalassiosira weissflogii, which can use Cd as a catalytic metal atom in their carbonic anhydrase, presumably conferring an adaptive advantage for diatoms that grow fast in the zinc-poor environment of the ocean surface （Xu et al., 2008）. In the terrestrial environment, Cd is known as a notorious toxin, causing phytotoxicity and human diseases such as renal dysfunction, osteoporosis, and cancers. The best known Cd-induced disease, Itai-itai （renal tubular osteomalacia）, is caused by chronic exposure to Cd via consumption of rice grown in Cd-contaminated paddy soil.

We produce p-harmonic morphisms by conformal foliations and Clifford systems. First, we give a useful criterion for a foliation on an m-dimensional Riemannian manifold locally generated by conformal fields to produce p-harmonic morphisms. By using this criterion we manufacture conformal foliations, with codimension not equal to p, which are locally the fibres of p-harmonic morphisms. Then we give a new approach for the construction of p-harmonic morphisms from R^m／{0} to R^n. By the well-known representation of Clifford algebras, we find an abundance of the new 2/3 （m ＋ 1）-harmonic morphism Ф： R^m／{0} → R^n where m = 2κδ（n - 1）.
