Flame retardant and mechanical properties of ammonium polyphosphate (APP), melamine phosphate (MP) and their combination with dipentaerythritol (DPER) in styrene-butadiene-styrene rubber (SBS) were studied. The results indicate that MP is more effective in raising limiting oxygen index (LOI) in SBS than...

Online learning is a learning way to use online education platform for learners. It could let the learners start learning at anytime from anywhere by removing the traditional education's time and space limit. As the online learning style becomes more and more popular, its main base environment has gradually...

Materials and the related manufacturing industry involve every area of the economy, and the corresponding talent demand ranks in the forefront of all industry professionals. However, the defects of current talent training mode and curriculum system limit the quality of talent training. In this paper,...

Volatile phenols are a class of protoplasmic toxicants which have caused inevitable environmental problems in many sea areas. This paper analyzed the content, pollution level and distribution of volatile phenol in bottom waters Jiaozhou Bay in May, September and October 1983. Results showed volatile...

This paper analyzed the contents, distributions and pollution sources of As in Jiaozhou Bay waters in 1983. Results showed As contents ranged from 0.19-4.89 g L-1,in the whole year, and were lower than Class I for As (20.00 g L-1) in National Standard of China for Seawater Quality (GB3097-1997). There...

This paper analyzed the content and distribution of Arsenic (As) in bottom waters in the bay mouth of Jiaozhou Bay in May, September and October 1983. Results showed As contents ranged from 0.15-2.30 g L-1 in bottom waters in the whole year, and were more lower than Class I for As (20.00 g L-1) in National...

Based on the investigation data on Cu contents in different seasons in 1983 in surface waters in Jiaozhou Bay, we analyzed the contents, pollution level and distributions of Cu. Results showed that Cu contents in May, September and October were 2.47-20.60 g L-1, 0.86-4.86 g L-1 and 0.77-3.00 g L-1, respectively....

Shadows of the sun position techniques can determine the place and date of the video. First, use Matlab to extract video files, extract n pictures at such intervals, after reading the picture get n sets of the shadow length l changes with time t. Known date from capture date calculate solar declination,...

Exception Handling in Java and other languages make it possible to raise exception and attaching exception handlers to particular blocks of code. In most research, more people focus on testing of exception handling of programs, Alexandre L. Martins [1] force the execution of exceptional path to improve...

In sewage treatment, the sewage whose carbon and nitrogen(C/N) ratios is less than 8 is defined as low C/N ratio sewage. This study contrasts the treatment effects under different C/N ratios in aerobic membrane bio-reactor. The experiment is performed in the following conditions: Temperature is from...

How UI designers and business engineers collaborate to development apps on Android platform conveniently and effectively is a difficult problem to tackle when projects get more complicate and need more effort. This paper compared the commonality and variability of MVVM with the commonly used MVC and...

To develop the Daucus carota L. var. sativa Hoffm. industry in our country, the further development and utilization of Daucus carota L. var. sativa Hoffm. agricultural resources, using modern processing technology to Daucus carota L. var. sativa Hoffm. processed into Daucus carota L. var. sativa Hoffm....

Friction stir based processes are solid state processes which significantly contribute to joining/processing of materials and surface property enhancement. It replaces conventional joining/processing techniques owing to their unique features such as reduced distortion, reduced porosity defect, reduced...

Under the background of the less connection between teachers and students in universities and the rapid development of the Internet, and according to the needs of students and teachers, the topic was to design and develop university research and academic platform prototype based on Android. First of...

In this paper, we extend research done in max-min fuzzy neural networks in several important ways. We replace max and min operations use in the fuzzy operations by more general t-norms and co-norms, respectively. In addition, instead of the Łukasiewicz equivalence connective used in the network of Reyes-Garcia...

A novel hybrid C+L band EDFA/RFA is designed to share the 1480 nm pump laser(s). The concepts are based on three-level amplification mechanism for the C band EDFA and Raman shift amplification mechanism for the L band RFA, respectively. It has the advantage to simplify the pump source design. The optimum...
