The public has been made aware that the lubricants used in machines can contaminate the soil and underground water supply.
Non-toxic and biodegradable lubricants have become a major issue especially when the lubricants involve contacts with soil, crops and ground water.
Biodegradability is the ability of a substance to be decomposed by the action of the bacteria into CO2, water, mineral compound and bacterial bodies.
The examples of the fields of application for environmental-friendly lubricants are [6]: outboard two strokes engine oils, chain saw and saw frame oils, hydraulic oils for forest and agricultural equipment, lubricants for sewage treatment plant, water weir plant and lock gate, lubricant for food machinery, metal working and metal forming processes and internal combustion engine and hydraulic system.

One-sludge Denitri-nitrification System Application in Reconstruction of Biological Treatment Stations in Russian Federation Elena Gogina1,a, Olga Ruzhitskaya2,b 1,2 Federal State Educational Institution of High Professional Education ‘Moscow State University of Civil Engineering’ (MGSU), Yaroslavskoe shosse, 26, 129337, Moscow, Russia, aGoginaES@mgsu.ru, bRuzhitskayaOA@mgsu.ru Keywords: wastewater, sewage treatment facilities, reconstruction, biological purification, biogenic elements.
Boundary values for phosphorous content also create special difficulty in water purifying and dumping it into the waters [1,3].
With all this, in any case reconstruction request creation modern state-of-the-art methods of flow capacity increasing in water treatment facilities, pumping stations and waste water network.
Moreover biological water treatment technologies using on water treatment facilities in our country don't provide the effective nitrogen and phosphorous compounds removing until today’s standard parameters for treated water dumping into the water basins.
Therefore treatment stations reconstruction and new methods of deep waste water treatment methods may solve the problem of waste water dumping into the waters of Russian Federation without treatment.

Electricity efficiency assessment of the building shows that the annual mechanical ventilation, Domestic Hot Water and lighting consumption (around 2080 kWh per year)is offset by 19 m2 of the mono-crystalline solar panels.
It allows a lower consumption of the building and lowering the water temperature by 0,5°C for high exterior temperatures.
The lighting, ventilation and hot water are taken into account in computing the electricity consumption.
Domestic Hot Water is considered electrically produced and consumes twice the energy for the first three scenarios for modelling larger loss due to poor insulation of the balloon and distribution.
The straw constructions are not more expensive than those made with traditional materials and their prices could lowered in the coming years with the rise in the number of professionals in this field.

This paper attempts to study the key technology and the specific production process in every link of 3D virtual campus system, and use professional software Uinty3D as the system integration platform, so as to construct a complete virtual campus system.
Summary To sum up, this campus navigation system is based on multi- platforms, its main function is to use the keyboard and mouse operation to roam the campus, other features such as in accordance with the specified path motion, hotkeys mouse, water effects, sky effects, multiple camera switching, etc.

The theme explored is rich and extensive: in the area of environmental protection, it includes forests, atmosphere, water resources, ecological resources etc.; science and technology refers to imagination and innovation on the space, the universe, spacecraft and future car, future construction etc.; energy source contains discussion on solar energy use, petroleum, coal mining etc..
Therefore, teachers are required to have advanced education concept, extensive professional knowledge and professional network technical, so that teachers can really play a organization, guiding and leading role in network explosive learning.

An example can be found by analyzing the rapid development of aviation industry, which demanded of professionals to search for more resistant materials, light and highly cost-effective.
The high hardness is achieved in this alloy by quenching and tempering process.In this heat treatment the sample was subjected to a temperature of 900 ° C for two hours to homogenise the microstructure, the cooling water and was then quenched after at 500 ° C for two hours.The hardness of aluminum bronze (UNS C 63020) reached 35 HRC.

Many communities have both comprehensive and professional computer networks serving community residents.
Some professional service networks provide specific medical services for communities and some specialize in community educational service development.
In community service network of Italy's Victoria state, residents could pay such public cost of water and electricity.

Currently, Building Information Modelling (BIM) is widely used in industries and its models are used as an exchange method for data between different professionals that participate in the design and construction of buildings [11].

The current learning process is not only linked to the acquisition of knowledge by the student but also demands that the student develop a series of abilities in line with their academic and professional profile [5, 6].
