Technical Basis

With the rapid economic development of China, Water transport constitutes a potential threat to the aquatic environment, human life and production. In this study, the complex ecological floating bed was studied in oil spill pollution control and ecological environment impact monitoring of inland waters. To explore the complex ecological floating bed in inland, especially the Yangtze River, inland waters. The purpose is to lay the theoretical and technical basis of controlling oil spill efficiently and long-term ecological monitoring. Ecological floating bed with PFU fixed oil-degrading bacteria water oil removal performance tests show that, which is very suitable for oil degradation in water.

В статье систематизированы основные критерии, необходимые для определения нормативных сроков эксплуатации бетонных и железобетонных конструкций, проведен анализ состояния отечественной и зарубежной нормативной базы в отношении требований к срокам службы железобетонных конструкций, рассмотрены основные нормативно-технические документы в области проектирования железобетонных конструкций зданий и сооружений по их жизнен-ному циклу. Описаны виды коррозионных повреждений железобетонных конструкций и определяющие их факторы, приведены согласованные на международном уровне модели долговечности для некоторых деградационных процессов. На основе проведенных работ подготовлены предложения по оценке коррозионного состояния эксплуатировавшихся железобетонных конструкций, их остаточной несущей способности, эксплуатационной пригодности, ожидаемого срока службы в заданных агрессивных условиях и методов определения нормативных сроков службы железобетонных конструкций. Даны предложения по разработке и актуализации ряда релевантных нормативных, технических и организационно-методических документов.

ABSTRACT Web-based homework (WBH) is an increasingly important phenomenon. There is little research about its character, the nature of its impact on student performance, and how that impact evolves over an academic term. The primary research questions addressed in this study are: What relevant factors in a WBH learning environment impact students' performance? And how does the impact of these factors change over the course of an academic term? This paper examines and identifies significant factors in a WBH learning environment and how they impact student performance. We studied over 300 students using WBH extensively for their coursework, throughout a semester in an undergraduate class at a large public university. In this paper, we present factors in the WBH learning environment that were found to have a significant impact on student performance during the course of a semester. In addition to individual and technological factors, this study presents findings that demonstrate that frustration with IT use is a component of the learning environment, and as a construct, has a larger impact than usefulness on student performance at the end of a course. Our results indicate that educators may benefit from training students and engaging them in utility of co-operative learning assignments to mitigate the level of frustration with the software in the WBH learning environment and improve student performance.
