In this example, the hydro mechanical components are thus the turbines, which are set rotating by flowing water and which drive the generators.
However, with the development of technology, electronics technology, updated file, e-portfolio research and application are not only limited to the field of education, have been extended to companies, professionals, services, public utilities, communities and other various fields in the society.
To the field of education, the e-portfolio develops from the initial portfolio assessment to its support for life-long learning and professional development.

For the protection of agricultural water security and agricultural sustainable development of circular economy, the city of Dalian during the second five to improve water use efficiency, will take the following measures to develop water-saving agriculture: (1) Water township and village enterprises.
Qualified enterprises to actively use water instead of fresh water for cooling water, industrial water recycling rate indirect cooling of 85%.
Implementation of the Farmland Water Improvement Project 1090, the new Small Water 1612 (Office), repair embankments 420, the new water-saving irrigation area of ​​13 mu, the new water-saving capacity of more than 2100 tons.Continue to do a good job supporting the construction of large-scale irrigation water, continue to spread irrigation, drip irrigation and other water-saving technologies and facilities.
To promote water saving in rice seedlings and water-saving farming, water-saving irrigation area of ​​more than 20,000 hectares.By2015, water-saving irrigation area of ​​Dalian City, 36.77 million mu, water-saving irrigation area of ​​the effective irrigation area ratio to 66%, the effective utilization rate of agricultural irrigation water to 55% 20% saving rate, a preliminary to a water-saving requirements of the development of ecological agriculture.朗读 显示对应的拉丁字符的拼音 字典 (3) Promotion of life saving appliances and desalination technology.
In addition to these water-saving measures, the city should develop more stringent water management system, a fixed water supply, improve water reward and punishment system to waste.

Therefore, color transparency of waste water becomes a major variable to indicate water clarity after the photocatalytic process occurred.
In order to test performances of the developed spectrometer, a waste water model was prepared by employing various concentrations of textile dye in water.
A qualitative examination is usually conducted by taking images of color changes of water.
Sample Preparation Solution samples were prepared by dissolving a textile dye (wantex blue) in distilled water.

As a kind of block binder material, the volume of the hydrated cement slurry shall shrink and get instable during setting and hardening of cement when the concrete block made of cement and aggregates has not reached the specified age, while the porous light block is liable to absorb water from its surrounding environment after reaching its specified age.
Concrete frame, blocks filled in the frame and mortar plastered on the block wall are different property materials, they are constructed in different construction stages, and they present different properties (thermal expansion coefficient, water absorption rate etc.) under external environment (change of temperature and humidity etc.), which lead to produce stress difference among them, the block wall shall crack once the stress difference is greater than binder force among the materials and the deformation can’t be harmonized.
For example: Dust, dregs and greasy dirt etc. on the wall surface are not cleaned thoroughly before plastering, the base course for plastering is not treated with sealant, the block wall has high water content or dry-wet alternation, mortar is not plastered by layers, and having the next operation is not until the former plastering mortar has set and gotten dry etc.
The related researches show that the more the water content, the more the contraction, and the more the chance (or crack width) of wall cracking.
Holes or slots for pre-embedded parts or pipelines should be chiseled by professionals with special machines and tools after mortar reaches design strength.

Since environmental impacts, economic efficiency and human healthy are crucial issues in the global context now, an increasing professional concern and interest in building performance have emerged in sustainable building field.
High-performance Building The recent decades have witnessed a growth of professional concern and interest in building performance.
HPOB design emphasizes an all-inclusive principle that expresses the good entire building performance, including the efficiency utilizations of land, energy, water, materials and other resources; decreasing environmental load and providing health comfortable working environment.

A full long-term vision is required to be able to plan in a responsible way, promoting the interaction of different professionals.
The energy analysis is undertaken with the software Archiphysik [14], which calculates the demand for heating, cooling, warm water, and home electricity.
Fig. 9 - Construction impacts regarding GWP Fig. 10 - Construction impacts regarding PEI Regarding the operation phase, the previously selected heat pump for the under-floor heating and solar collectors for the production of the domestic hot water (integrated with the heat pump when needed) are considered.

It is tough to improve the amount of the clients of the venues which service the professional team because of the special clients, so the other ways of realizing the low carbon operation should be explored.
The control of the consumption of electricity energy includes refrigeration, lighting, air condition; the control of the consumption of heating energy includes heat supply, hot water.
The carbon compensation system should be established for the professional sports team using the high carbon venues.
For example, the member of the professional sports team could call for the low carbon conception by welfare AD, or plant the trees.
