Magnetic fields in the Planck theory of sonoluminescence

引用

Nuclear Science and Techniques 1998年第4期9卷 221-226页

作者： Prevenslik T V (2E Greenery court, Discovery Bay, Hong Kong )

Sonolundnescence (SL) observed in the cavitation of water may be explainedby the Planck theory of SL that treats the bubbles as collapsing miniature masers havingoptical waves standing in resonance with the dimensions of bubble cavity. Microwaves arecreated from the Planck energy of the standing waves provided the bubble wall may be treatedas a perfect blackbody surface. In the ultraviolet, liquid H2O is strongly absorbent and thebubble approaches a Planck blackbody enclosure. The micrwaves are created at frequenciesproportional to the bubble collapse velocity and are absorbed by the dipoles of the H2O andother bubble wall molecules. Intense electric fields develop as the liquid H2O bubble wallundergoes dielectric polarization. By this theory, free electrons are created in SL as the electricfields breakdown; the presence of free electrons is required if any magnetic field effect is to beobserved in SL. Both local and global magnetic effects on SL are described. The local effectis based on the magnetic pressure due to the electrons moving as currents inside the *** global effect is an accumulation of local c’ffects at the voids throughout the liquid H2Ocausing a reduction in the bulk modulus. Numerical solutions of the Rayleigh-Plesset (R-P)equation are presented that show the effect of applied magnetic field on SL to be the globaleffect causing a reduction in the bulk modulus. consistent with the Planck theory of SL, theR-P simulations show the suppression of SL intensity with magnetic field to be parabolic andthe SL intensity to be linear with collapse velocity.

质粒pcE31含有在P_L起动子控制下的重组era基因,在大肠杆菌中、42℃诱导高表达出Era蛋白,经溶菌酶处理裂菌、沉淀离心洗涤后所得的纯Era是不溶的,生物活性也不高。改在40℃诱导2h,在Era底物GDP的存在下裂菌,60％以上的Era处于可溶状态。用蛋白酶抑制剂防止Era蛋白降解,经盐析、Q-SepharoseFF柱层析分离,获得可溶性纯Era蛋白。该蛋白能特异地与鸟苷酸结合、并具有GTP酶活性,表明Era是一种G蛋白。动力学定量分析结果:在4℃时,每分子Era肽链能结合一分子GTP或GDP,表明所纯化的Era蛋白几乎都具有活性;4℃下,Era蛋白与GTP或GDP结合的解离常数,分别为5.49和1.01μmol/L;37℃时,Era蛋白GTP酶的Km值为9.0μmol/L,催化GTP水解的最大速度为9.8mmolcTP/mol Era/min。

PEROXIDE BLEAcHING OF LOW-FREENESS TMP

天津科技大学学报 2004年第S1期 92-96页

作者： Y. Ni Z. Li G. court canada Dr. Jack McKenzie Limerick Pulp and Paper Research and Education centreUniversity of New Brunswick E3B 6c2 Fredericton Irving Paper NB

Peroxide bleaching is an essential unit operation to produce value-added mechanical pulp-based paper grade. In this paper, we presented the results from peroxide bleaching of low-freeness TMP for the production of Sc paper. Two aspects were addressed; the effect of pulp strength and the formation of anionic trashes. The strength properties, such as tensile, burst and zero-span tensile, are improved after the peroxide bleaching process. The amount of anionic trashes formed is almost proportional to the hydrogen peroxide charge.
