“…Newmark, a British translation theorist, divides all kinds of translated texts into three basic text forms according to the genre, namely "expressive text," "informative text," and "calling text." "Expressive text" refers to creative works, whose language has aesthetic characteristics, generally including poetry, novel, drama, and other genres [8]. "Informative text" usually has simple text and strong language logic.…”

The impact of publicity translation and communication is a critical link in China’s international public relations strategy. The primary goal of the critical task of “disseminating Chinese culture and transmitting China’s image” is to improve Sino-foreign cooperation and ensure that the world understands and recognizes China. It entails the movement and spread of various cultural elements across countries, and it affects every aspect of human society. It is a necessary means of communication between people, nations, and countries. We should take into account many differences between the East and the West in terms of language, culture, ideology, and so on when translating. The tone of the text is determined, and the writing is concise, which aims to analyze ideas, clarify viewpoints, and achieve the purpose of publicity, among the factors affecting the communication effect of publicity translation. It possesses qualities, such as accuracy, politics, timeliness, monosemy, objectivity, and integrity, among others. This paper will investigate the characteristics of the factors affecting the communication effect of publicity translation and text types from the lexical and syntactic levels, as well as the specific application of text type theory in the communication effect of publicity translation.

+39 0498271608Imidacloprid (I) and thiamethoxam (T) are widely used neonicotinoid insecticides with high persistence in the environment and thus included in the watch list of substances for European Union-wide monitoring reported in the Decision 2015/495/EU. In this work we report and discuss the results of a study in which aqueous solutions of I, T and I + T were subjected to advanced oxidation by air plasma produced by negative DC corona discharges above the liquid surface. The oxidative degradation of each pollutant was investigated by monitoring the rate and the products of its decay when treated alone and in the presence of variable amounts of the other compound. The results show that both I and T are readily degraded and that mineralization can be achieved in this process, as proven by the measurement of the residual organic carbon and by the quantitative conversion of chlorine and sulfur into inorganic chloride and sulfate, respectively.The major organic intermediates formed during the complex stepwise oxidation of I and T were identified and monitored by HPLC-MS/MS analysis. The results of kinetic studies show that both for I and T the reaction rate depends inversely on the insecticide initial concentration, that I and T have similar reactivities and that they do not interfere reciprocally in any specific way when treated in mixture at a total concentration of ca 10 -4 M. Based on literature data and on previous results with the same reactor, it is reasonable to propose that the oxidation of I and T is initiated by the reaction with OH radicals.

“…It has been reported to cause severe environmental problems and health risks to biota due to its highly toxic and bioaccumulative nature . Recently, the degradation and abatement measures of THIA have received great attention, − especially for its advanced degradation. Among these degradation approaches, catalysis has earned a vital position credited to the ease of process operation, high efficiency, and fast degradation kinetics …”

MIL(Fe)/Fe-doped nanospongy porous biocarbon (Fe-SPC) composite was fabricated from MIL-100(Fe) via in situ growth on a unique Fe-doped nanospongy porous biocarbon (Fe-SPC) and was used as Fenton-like catalyst for advanced degradation of thiamethoxam (THIA). Fe was loaded on silkworm excrement and calcined to Fe-SPC with nanospongy and high sp 2 C structure. The in situ growth strategy embedded the Fe-SPC into MIL-100(Fe) crystals and formed conductive heterojunctions with an intensified interface by Fe-bridging effect, which was confirmed by negative shift of Fe 3+ binding energy in X-ray photoelectron spectroscopy. MIL(Fe)/Fe-SPC composites exhibited high degree of crystallinity and surface area (Brunauer−Emmett−Teller: 1730 m 2 /g). Liquid chromatography−mass spectrometry and density functional theory simulations demonstrated that THIA was converted to a relatively stable compound (C 4 H 5 N 2 SCl), which could be captured by MIL-100(Fe) with strong chemical bonding energy (Fe−N, −587 kJ/mol), followed by a significant geometric distortion, resulting in a thorough degradation. Efficient charge separation and synergistic chemisorption-catalysis strategy resulted in the high catalytic activity of MIL(Fe)/Fe-SPC. The composite catalyst concurrently exhibited high mineralization ratio with 95.4% total organic carbon removal (at 25 °C and 180 min) and good recycling ability under wider neutral/alkaline conditions. Endorsing to these intriguing properties, MIL(Fe)/Fe-SPC can be deemed an efficient contender for removal of hard-degradable pesticides and other environmental pollutants in practical applications.
