An entrepreneurial framework is defined by some factors such as: entrepreneur, along with his personal and professional characteristics, who is the main actor of the so-called entrepreneurial process; business idea that entrepreneur wants to turn it into profitable business; market opportunity, which demonstrates that the business idea is valid, has novelty and can be fructified and developed; business plan, that needs to be well prepared in a very detailed manner and containing long run strategies; business start-up resources, including time resources allocated to implement the business plan, physical resources, information, financial and human resources; the environment where the business will be active; technology needed to develop the business activity.
Wind energy and water energy is produced by the kinetic energy, geothermal energy is produced by high temperature of water or steam, biomass energy is produced by wood, crops and plant mass and solar energy is produced by direct or diffuse sunlight.

The costs associated with the provision and maintenance of drinking water and wastewater infrastructure represents a significant financial demand worldwide.
It may be intended to be used by municipalities and professionals faced with problems or potential deterioration of sewerage.

Another possible method of dissipating the heat from the thermoacoustic air conditioning system is involved heat absorption by water.
This is because water has high heat capacity and it would absorb the heat quickly.
This process is used in many professional-grade thermoacoustic researches where helium gas has led to increase the efficiency and heat transfer across the stack.

It’s a professional producer of PMSM (permanent magnet synchronous motor), electromagnetic pump, stepping motor and DC motor.
Change water after every washing, not reusing the water.

Jacket structures are designed for a specific water level (LAT).
For studying effects of water level variation on structural behavior, the water level changed and each model studied separately.
In order to study the effect of design water level on structural elements responses after water level rise, four models with different design water level are made and Von-Mises stress are considered.
The effect of water depth variation on deck displacement As this figure shows, increasing the sea water level has considerable effects on deck displacement especially for structures with high operation water depth [19].

The amount of heavy metals in addition to these assumptions spread main propagation in atmosphere, soil and water way neglect.
The causes of pollution is mainly due to the As and As containing metal mining, smelting, water, waste gas and waste residue containing AS waste will be generated.
Waste water and waste alkali, plastic, batteries, electronics and other industrial emissions will also cause pollution.
The main source of Ni in soil is from weathering of rocks, atmospheric dust, irrigation water (including waste water containing Ni), fertilization, plant and animal residues decay.
Along with the mine drainage and rainfall make it into the water environment (such as rivers) or directly into the soil.

Moreover, the curves also can be employed in checking longitudinal strength in waveform waters.
Thirdly, the area of cross sectional (Ai) under water for each station or sub-station should be collected respectively in the Bonjean tables, basis on the variant draft on the each station, linear difference as necessary.
In fact, shipyards or design institutes are able to conveniently provide the detailed Bonjean’s curve tables making use of the professional design software, such as COMPASS to CCS, NAPA and PASSE design software which are easy to output Bonjean’s curve tables in high precision [8], of course, electronic data better.
The figure of displacement would be displayed within one or two seconds soon after just putting drafts in six-surface and measured density of sea water.

Straw-bale, made of stem of a variety of grain crop, such as straw, ryegrass and so on, is a kind of new green building material after compressed and fashioned by professional machine.
While, active usage means to set up solar water heater on the surface of sloping roof.
As for solar water heater, solar collector, being the core part, could heat cold water, then the warmer water is preserved in the storage tank, at last they are transferred to washroom and kitchen so as to make sure that there is enough hot water that could be supplied to peoples’ daily life.
In winter, hot media, commonly composed of water and antifreeze solution, is heated by hypothermal terrestrial heat.

Big trees can increase the humidity and oxygen content in air, meanwhile their substantial amount of leaves can adsorb dust and play an important role in water conservation, and reduce rain’s erosion to the earth [1].
In big tree transplanting, because of the lack of professional tools, materials and machinery, human are main forces in most cases, and in such condition the soil balls are easy to collapse.
Water and soil erosion, flood and other natural disasters caused by the big trees transplanting.
Decline in ecological function of forests is the fundamental cause of water and soil erosion.
Destruction of forests will cause declining in their effects of containing water, holding soil, regulating runoff, reducing flood and preventing drought, and therefore result in water and soil erosion, irregular floods and droughts and even simultaneous happening of flood and drought.

Through the validation, the forecast model of maritime accidents is feasible. 0 Introduction With the development of our economy and the boost of our international trade,water transport has become more and more busy.Up to 2011, port throughput capacity of china is up to 83.2 billion tons which is 800 times more than that in the initial period of china, an increase of 14% more than that in 2008.
The water transportation becomes busier and ship traffic density is increasing constantly along with the development of water transportation, so safety of navigation of the ship is seriously effected.
At the same time, there is a trend towards bigger and more professional on vessels, which increases the risk of accident of ships.
This chapter, from the related factors analysis which has impact on maritime accident, adopts the most widely used error back propagation algorithm (BP algorithm, back propagation), based on the factors affecting the BP neural network prediction model, as the model’s self-organizing, adaptive, parallel processing characteristics and strong ability of nonlinear mapping, the maritime accident forecast has the traditional single model incomparable superiority and adaptability. [3] 1 The analysis of maritime accident influencing factors Water transportation system is a complex nonlinear system, so factors affecting the maritime accident are also complicated.
Shipping conditions mainly refers to the shipping industry developed degree, the more developed water transport is, the greater the amount of cargo transport is, the larger shipping amount is, it is bound to affect the traffic on water.
