A novel mechanism for jumping in the indian ant<Emphasis Type="Italic">Harpegnathos saltator</Emphasis> (Jerdon) (Formicidae,Ponerinae)

The Indian antHarpegnathos saltator may be unique among insects in using its jumping capacity not only as an escape mechanism but also as a normal means of locomotion, and for catching its prey in flight. High-speed cinematography used to analyse the various phases of the jump suggests thatHarpegnathos employs a novel jumping mechanism to mediate these behaviours: namely the synchronous activation of its middle and hindlegs. Electrophysiological recordings from muscles or nerves in pairs of middle and hindlegs show remarkably synchronous activity during fictive jumping, supporting the synchronous activation hypothesis.Harpegnathos is not the only ant to jump, and a cladistic analysis suggests that jumping behaviour evolved independently three times during ant evolutionary history.

三乙基苄基氯化铵合成反应动力学研究

用电导法分别测定了三乙基苄基氯化铵合成反应在乙醇、正戊醇、１,２－二氯乙烷三种溶剂中的反应进程,此反应在三种介质均为二级反应;求出了不同温度下的反应速度常数、反应活化能、指前因子以及活化熵变;１,２－二氯乙烷是非质子性溶剂,对三乙基苄基氯化铵合成这类双分子亲核反应有利。乙醇溶剂的反应速度随温度升高而明显加快。     

Relationship between giant magnetoresistance of NiFe/Cu multilayers and their microstructures

The (111)-orientated NiFe/Cu multilayers were prepared by magnetron sputtering method. At room temperature, saturation magnetoresistances of NiFe/CU multilayers oscillate as a function of Cu spacer layer thickness. Two peak GMR values of 19.4%, 11.6% and 11.2%, 1% appear, respectively, at Cu sublayer thickness of t_Cu,= 1.0, 2.2 nm while the deposition pressures are 0.25 and 0.45 Pa. X-ray small-angle reflections and diffuse scattering at Cu K-edge (8.979 keV) by synchrotron radiation source were used to characterize the interfacial roughness. Diffraction anomalous fine-structure scattering (DAFS) was performed to investigate the local structure of NiFe and Cu sublayers. Results show that the deposition pressure has effect on interfacial roughness of the samples obviously, and the interfacial roughness also affects the GMR values of the samples strongly.
