用尖吻蝮蛇毒、蝮蛇毒及抗蛇毒血清处理小鼠S_(180)、EAC腹水癌的初 步观察

尖吻蝮蛇毒、蝮蛇毒及抗蛇毒血清能使接种S_(180)、EAC腹水癌的小鼠 明显延长存活时 间、降低接种率, 但不能完全阻止癌细胞生长。体外具有较明 显的导致癌细胞肿胀、膜破裂、核纤维化、坏死等作用。腹水酶活力测定及抗血 清初步研究结果表明, 癌细胞病变中产生的某些抗原物质可能与蛇毒中的酶和 毒蛋白相近。因此注射蛇毒后可在体内产生相关抗体, 中和癌细胞产生的毒素以 达到治疗目的。图1表6参10

Upper and lower bounds of 180 degrees unit element of a ridge waveguide: Calculations and measurements

The upper and lower bounds on the actual solution of any microwave structure is of general interest. The purpose of this letter is to compare some calculations using the mode-matching and finite-element methods, with some measurements on a 180 degrees ridge waveguide insert between standard WR62 rectangular waveguides. The work suggests that the MMM produces an upper bound, while the FEM places a lower bound on the measurement. (C) 2001 John Wiley & Sons, Inc.

The Rhetorical Construction of Corporate Logos

This research is set in the context of today’s societies, in which the corporate visual symbology of a business, corporation or institution constitutes an essential way to transmit its corporate image. Traditional discursive procedures can be discovered in the development of these signs. The rhetorical strategies developed by the great classical authors appear in the logo-symbols expressing the corporate values of today’s companies. Thus, rhetoric is emerging once again in the sense it had many centuries ago: A repertory of rules that, paradoxically, standardizes the deviations of language and whose control is synonymous with power. The main objective of this study is to substantiate the rhetorical construction of logos using as a model of analysis the classical process of creating discourse. This involves understanding logos as persuasive discourses addressed to a modern audience. Our findings show that the rhetorical paradigm can be considered as a creative model for the con­struction of an original logo consistent with a company’s image.

Ordered 180 degrees ferroelectric domains in epitaxial submicron structures

Large range ordered La(0.7)Sr(0.3)MnO(3) and SrRuO(3) epitaxial dots were fabricated by pulsed laser deposition using stencil masks and were embedded in ferroelectric PbTiO(3) epitaxial films. PbTiO(3) films grown on top of La(0.7)Sr(0.3)MnO(3) dots form arrays of 180 degrees domains that are switchable and have good ferroelectric properties. PbTiO(3) films made on top of SrRuO(3) dots have a monodomain polarization state. These observations point out the importance of the electronic properties of the bottom electrode in the selection of a preferential polarization state in epitaxial ferroelectric films and propose a route of fabricating large arrays of switchable 180 degrees ferroelectric domains.
