If the mesh is Lagrangian, the Lagrangian material coordinates of nodes are time invariant, i.e. the nodes are coincident with material points.
In the Lagrangian mesh, nodal trajectories are coincident with material point trajectories, and no material point passes between elements.

Introduction Zinc oxide (ZnO) is one of the most important II–VI group wide band-gap semiconducting materials which have many promising applications such as, optoelectronic devices, field emitters, solar cells, and sensors[1-6].
Besides temperature, the concentration of the Zn(NO3)2×6H2O electrolyte solution plays a crucial role in building these novel self-assembled nanostructure materials.

In specific conditions of temperature and pressure, the aluminosilicates may, in strong alkaline environment, react among themselves, giving place to the formation of stable materials of high mechanical strength, able to support high levels of temperature and resistant to acid action.
Introduction The alkaline activation is a policondensation reaction that provides materials with high chemical resistance and excellent mechanical behaviour.
The raw materials for this reaction are mainly the aluminosilicates that form more than 75% of the solid part of the terrestrial crust.
A plan has been organised following the above-mentioned objective: � Determine the sufficient time of exposure to temperature � Determine the ideal temperature for dehydroxilation � Characterize materials in different phases of both processes Experimental In this research work, commercial kaolin from the area of Esposende in Northern Portugal has been used.

In the 1990s with the advancement in simulation technology, designers were able to develop even better shapes for the wind turbine. [7] [11] From twentieth century onwards, advancement in the fields of materials and manufacturing enabled engineers to use more advanced materials such as fiberglass and better manufacturing processes such as precision moulding, additive manufacturing etc.

The tensed piezoelectric material tilts the comb structure upward, and the compressed piezoelectric material tilts the comb structure bends downward, as shown in Figure 3(a) and (c).
In the proposed model we assumes that insulator layer, bonding layer and electrode layer are negligible because elastic substrate and piezoelectric materials layer are much more thickness than other layers.
As the material properties of the thin film PZT layer have not yet been determined, and hence the values of the bulk PZT 52/48 are chosen.

The game analysis between agricultural raw materials suppliers - farmers or farms and food producers with government's incentives Farmers who grow morden high quality crops are given subsidies by government (the valuation is U), which makes the production cost of farmers can be compensated to some extent, when the cost is C2 (C2 The government can give incentives to croppers ( farmers) with subsidies in the source of food supply chain, and encourage them to grow high quality crops, from the source to ensure the safety of food supply of raw materials.
But we also see clearly that there are several reasons effect the food quality ,namely the irrational use of pesticides; abuse of additives and packaging materials in processing and packaging ; negative effects of modern science and technology; lack of effective detection techniques; and imperfect monitoring network and so on.
