工艺管道预制划分焊口安装属性原则的研究

工艺管道预制按焊口安装属性可划分为预制口和现场口,将预制口进行集中施焊,以减少项目现场的焊接工作量。传统简单粗放的划分方式已不适应如今高标准高效率的工厂化预制生产模式,通过对工艺管道相关的连接管件、切割下料、组对要求、焊接工艺及现场安装规范等多方面因素进行考量制定出标准化的划分原则,按此原则对项目工艺管道焊口属性划分出的预制口进行集中预制焊接,完成的管构件运至现场安装,显著提高生产工效,缩短工期,节省工程成本。

现场植入式口播广告的审美研究——以《我想和你唱》为例

为满足广告主的需求,广告形式不断地创新。近几年来,综艺节目里出现了一种新型的广告形式,即由节目嘉宾在节目行进过程中现场植入广告。但是这种形式的现场植入式口播广告常常会打断节目的整体性,给观众带来一种突兀感,而且,在并不恰当的时机,为了完成广告任务,生硬的插入广告在一定程度上会使观众产生反感和厌恶的心理,很难达到理想中的广告效果。

Urban Transformations and the Importance of Public Spaces and Urban Places

The aim of this essay is to understand the relationship between the media and the city. It is based on qualitative text analysis of theories and arguments from within urban sociology and media and communication. Two questions are posed：（1） what assumptions are the relationship characteristics between the media and the city based on？ and （2） what communicative changes in the relationship between the media and the city are historically noticeable？ The results are that： （1） the characteristics of the relationship between the media and the city are based on the assumption that the role of the media in society is closely intervened with the rise of the modern city and the urban society; and （2） four phases of communicative changes up until today are noticeable. First-hand experiences decreased and second-hand contact became more common, more shallow and rational due to the population sizes of the modern cities. The first-hand experiences continue to decrease but also the second-hand experiences. The latter is due to the increased importance of visual representations, and that the perceptions of the city became more important. As consequences people no longer always know from where their experiences steam. The implications of the characteristics of the relationship between the media and city are further discussed in terms of the importance of public spaces and public places.

Physico-Chemical Analysis of Korapuzha River and Estuaries

Korapuzha is a short river of 40 km with a drainage area of 624 km^2, flowing from dense forest and empties into the Arabian sea. It is formed by the confluence of two streams Agalapuzha and Punnoorpuzha. In this study the samples were collected from Agalapuzha, Punnoorpuzha and Korappuzha, Korapuzha estuaries. The temperature and pH were monitored on the site and the remaining parameters were analyzed in the laboratory. The physical quality parameters such as color, odor, appearance and chemical quality parameters such as pH, alkalinity, chloride, nitrate, nitrite, sulphate, ammonia, dissolved oxygen, total solids, total hardness, and iron have been evaluated. Compare the physical and chemical parameters. The physico-chemical analysis shows that the samples have high level of salinity, sulphate, total solids and total hardness. The results show that the water is affected by the intrusion of sea water into the river by excess excavation of sands from river for the construction of buildings and other anthropogenic activities which leads to environmental destruction.
