This device is manufactured in the laboratories at University of Wasit, college of engineering.
General Introduction The experiments were carried out in the sanitary engineering laboratory at University of Wasit, AL-Kut.
It is chosen to not be matching with other devises color; they are already existed in the sanitary lab of the college of engineering.
Acknowledgements We thank the Wasit University, College of Engineering, to give us this opportunity to work on this project in their laboratories (water engineering and sanitary laboratories).

Introduction Increased awareness of the economic and social effects of aging, deterioration and extreme events on civil infrastructure has been accompanied by recognition of the need for advanced damage detection and structural health monitoring techniques.
Experiment setup and results For testing purpose we have prepared two engineering plastic samples.
According to Fig. 12, the damage in the engineering plastic sample can be well distinguished by principal component analysis.

Beryllium plays an important role in the development of nuclear technology, defense, and aerospace, which make beryllium become a strategic and critical engineering material.
Beryllium has also gained attention as a “strategic, critical” engineering material [1].
China’s first High Flux Engineering Test Reactor uses beryllium as a reflective layer.
Beryllium Advanced Inertial Reference Sphere of the United States Peace Guardian Intercontinental Ballistic Missile In the inertial navigation systems of fighter aircraft, carrier rockets and civil aviation, beryllium precise navigation instruments are also widely used.
The application level of beryllium in strategic nuclear energy, advanced fields, and major scientific engineering construction reflects to some extent the comprehensive strength of a country and the level of national defense military technology.

The results of this study will be used as a basis for further research and hopes of getting better alternative engineering materials in the form of composites.
Introduction Inventories of engineering materials from metals are decreasing, so it takes a lot of innovation to make new materials used in the engineering fields.
The process is doing by combining two or more materials in particular conditions to produce engineering materials with specific mechanical properties.
It has been widely used in engineering, high heat resistance, absorbs low water, and excellent dielectric characteristics.
In contrast, bottom ash tends to be used as reinforcement for composite materials in the field of civil engineering such as mix materials for highways or building concrete.

Analysis of Advantages and Disadvantages of Sewage Treatment Technology and Its Application in Rural Areas of Beijing Ying Li1, a , Jing Zhou2,c 1Key Laboratory of Urban Stormwater System and Water Environment (Beijing University of Civil Engineering and Architecture), Ministry of Education, Beijing, China a liy@bucea.edu.cn , b 247420322@qq.com Keyword: rural; sewage treatment; advantages and disadvantages; analysis Abstract: At the current stage, sewage treatment technologies in rural areas of Beijing are applied frequently, they have their own advantages and disadvantages in the specific implementation process.
Municipal sewage and industrial wastewater Sewage treatment and utilization of ecological engineering in Dongying city, 100,000 t / d design treatment capacity, about 110 hm2, a sewage treatment plant with more perfect design of stabilization pond treatment system the domestic application at home and abroad; Chang Village, coal mine aerobic pond, for removing pollution of Jianhe by mine water, in recent years, the mine has invested more than 0.4 million Yuan to convert a disused mine into a aerobic pond with volume of 150,000 m3, treat sewage 82,000 m3/month .

In the first decade of the 21st century, great progress has been made in the following fields: 　Energy Science and Technology 　Motivation and Power Engineering 　Environmental Science and Engineering 　The Development and Utilization of Resources 　Nevertheless, the experience of industrial civilization during the recent 300 years tells us: technology can not save the environment, on the contrary, it is often an accomplice who accelerates environmental degradation. [3] The Species’ Patterns of Behavior of Mankind Endlessly Change the Biosphere As a species, in order to develop the economy, mankind keeps making dams, cutting down trees, mining in mountains, constructing cities.
Mankind fights against each other from cold weapons to hot weapons; from tribal war to civil war, international war, world war and even dreaming of space war; from the land into the air and underwater.
