The topics that will be presented in this Volume will be going to the encounter of a variety of scientific and engineering disciplines, such as chemical, civil, agricultural, mechanical engineering, etc…The book is divided 10 chapters that intend to be a resume of the current state of knowledge for benefit of professional colleagues, scientists, students, practitioners, lecturers and other interested parties to network.
In Chapter 4, Fernandes Magalhães et al. provide a numerical study of the water/oil separation process through the tubular ceramic membrane.
In Chapter 5, Oliveira et al. present a numerical study of the flow of oil and water in cylindrical ducts with an elliptical cross-section by using the Ansys CFX software.
Results of the velocity, pressure and volumetric fraction distributions of the oil and water phases are presented and analyzed.
This is followed by Chapter 6, by Verusca de Oliveira Lopes et al. who present an analysis of the performance of a concentrating hydrocyclone in the separation of ore and water by CFD.

Introduction Over the recent years, biologists, physicists and health professionals have increasingly focused their attention on the development and application of nanopharmaeuticals in medicine.
A very bright example of nanocapsule carrier is a liposome, which is a closed water bubble surrounded by one or two layers of phospholipids.
The technique of nanocolloid preparation includes the following stages. 2 ml of water for injections is added to vial B.
Vial A is then placed in a boiling water bath for 15-30 minutes and after that it is cooled under cold running water.
The resulting mixture is heated in a boiling water bath (70-80 ºС) for 30 min and then cooled to room temperature.

Due to the constraints of small nacelle space and poor accessibility, appropriate and professional repair work is extremely difficult for maintenance staff and the quality of maintenance work is difficult to be guaranteed.
Once the fire extinguishing system is triggered, ventilators and fire dampers in ventilation ducts in protection zone automatically shutoff, water sprinkler and water spray extinguishing systems are mainly used for the protection of the tower structure, equipment and the safety of life.
In more developed wind power technology countries, a number of professional security companies has proposed a variety of fire protection solutions for wind turbine.
Fine water spray nozzles, specially designed to use the minimum amount of water to get the maximum extinguishing effect, were installed on the key parts of the wind turbines, such as main bearings, gearbox, brake system and generator, etc.

Analysis procedure was the following Water extract from the taken plaster was made and subsequently observed by means of transmission light microscope.
The sample was place in the eppendorf (Eppendorf) and supplemented with deionized water for the volume 1 ml.
From such a modified sample 10 µl of water extract were taken.
Owning to this more water accumulates in lower floors, that is greater humidity and so better living conditions for the growth of algae and fungi.
It is necessary to cooperate with professionals on sciences, such as phycology, (the study of algae), microbiology, bionanotechnology so that we could deal with the issues of biotic infestation of frontages and to apply advanced laboratory methods detecting their presence and growth.

This can explain why system with photocatalyst suspended in water or fluidized in air has shown the higher efficiency than immobilized one.
Besides, relatively poor initial design even worsened its performance so that some environmental professionals concluded that photocatalytic system had inherent disadvantages.
As a pretreatment step, dipping POF in acetone, followed by washing off remained residue with distilled water was conducted.
TiO2 suspension (5 wt%, pH 4.5) in purified water (Milli-Q, 18M� ) was prepared and dispersed sonically.
This reactor is with both solar concentrator to increase light intensity and water filter to prevent POF from melting (light guided reactor in Fig. 4).

Mountains, plains and hills make up a pattern of 70% mountains, 10%water and 20% arable land.
Yichang is rich in mineral and water resources, famous for its Three Gorges Dam, Gezhouba and other large water conservancy projects, and it is also rich in forest, tea, specialty fruit, chestnut, walnut, edible mushroom and other agricultural products.
As a provincial deputy city, Yichang is a hub of traffic, water transportation, logistics and economic development of western Hubei and eastern Sichuan.
At present time, industry is mainly on technology-intensive enterprises such as water conservancy and chemicals.
Lastly, shortage of professional technical city planner and the confined power on local planning personnel and fiscal department restricts the urbanization development in Yichang.

Heat transfer between gas-solid two-phase flows and water in single-tube is simulated.
Water flows in the horizontal tube at the speed of 0.05m/s.
The water closer to the wall has higher temperature than that near the center axis.
As shown in Fig. 5, the outlet temperature of water increases with the smoke velocity.

Compare to other finite element programs, it shows more convenient and professional for it focuses on geotechnical issues.
(1) Assumption of failure surface is not required, result will directly show us the position of the failure surface; (2) Constitutive relationships can be fully considered by method of finite element as well as complicated boundary conditions; (3) Repeated trial are not needed by the procedure named Phi-c supplied by PLAXIS; (4) PLAXIS focuses on geotechnical issues, so that it is more professional in this area than other similar finite element programs.
