For soil aggregate was the basic unit of soil structure, its content distribution and stability affects soil pore conditions as well as migration methods and ways of the moisture in the soil structure [4].
The results indicate that planting fruit trees in natural soil layer significantly promotes soil structure recovery and soil structure stability was increased with increasing cultivation years.
Thus, it promotes the stability of soil structure.
The increase of the content of soil organic matters promotes the formation of aggregate structure in the soil layer, improves soil structure and enhances soil erosion resistance.

Recently, new theories for structures are developed in literature, Houari et al. [26]. have used new simple three-unknown sinusoidal shear deformation theory.
Thus, the scale coefficient (e0a) in the modelling will lead to small-scale effect on the response of structures at nano size.
The frequency ratios (χN) exhibit a dependence on the structure characteristic of armchair carbon nanotube n.

The choice of a suitable glass matrix is important to obtain the excellent and stable glass structure.
[12] only discuss and focus on Er3+ local structure and its optical properties in ZnO-PbO Tellurite glass.
Similarly the molar volume can be used to describe the network structure and arrangement of the network structure and arrangement of the building unit.
These phenomena occur due to the forming of NBO in the structure of the glass.

The graphene is constituted by a monolayer of carbon atoms having a hexagonal honeycomb structure of the two-dimensional crystals (Fig. 1) [5].
The 2D graphene structure can be seen as formed all sp2 hybridized carbon material of the basic constituent unit (Fig. 2).
This structure will have important applications in launch site and super capacitor electrode materials [43].
Synthetic yield is not high, and in most cases can’t be obtained monolayer structure.
Organic synthesis method Precise control of molecular structure and properties. mild experimental conditions.

The spatial structure of disaccharides: a - lactose, b – sucrose Lactose refers to reducing disaccharides.
Thus, the carbohydrates behave differently in aqueous solutions, but are combined by their structures of cyclic molecular fragments - pyranose cycles.
The latter is associated with the action of sucrose contained in sSCD, which has a retarding effect on the structure formation of the cement system.

Figure 3 Is the structure chart of TRIZ Table 3 QFD-based approaches for intelligent patient bed design.
In QFD2 ( refer with : Fig.4) ,which is responsible for product structural design, design for assembly (DFA) is used first to simplify product structure.

Patients do not need to tell the nurse what they weigh because their weight, vital signs, and blood chemistry values are viewed on the nurse's hand held device.
These multi-purpose units are equipped with sensors that monitor vital signs and blood and gas chemistries and can provide suction, ventilation, intravenous infusion, and defibrillation.

Physics and chemistry of the matter near the surface are consequently different from those of the bulk and this will show on vibrational spectra.
On the contrary, ionic structures are poor Raman scatters and their analysis is difficult and complex.
This model can be applied to compounds with homogeneous structure in 3 directions (spherical model).
The broadening is obvious in the figure and depends on the structure.
“Main” peaks of 3C structure are centred at 796 (Transversal Optic) and 966 (Longitudinal Optic) cm -1.

Due to short-range stress field the influence of interfaces is primarily based on their atomic structure.
All those aspects of boundary behaviour are strongly influenced by the boundary chemistry including various segregation phenomena.
Let us mention one example here - structure, energy and fracture stress were studied on molybdenum bicrystals [1-4].
The fcc structure is reached at the c/a ratio equal to v2 when the tetragonal uniaxially deformed structure is attaining again cubic symmetry.
Consequently, the lattice dislocations can react differently with diverse dislocation interfacial structures.

The downloaded 3D structure is still in SDF format, thus cannot be utilized further.
The majority of the 3D structures were obtained from PubChem and additional structures were obtained from RCSB PDB.
The protein docking results are as follows, with chemical structures taken from PUBCHEM database (Table 1).
The 3D structure fot the docked protein with the ligand I.

Despite intensive research and development of biomaterials for bone tissue engineering, especially for osteoporotic bone healing, the properties of the fabricated biomaterials are still far from those of unique composite structure of natural bone and desired therapeutic effect not achieved.
Introduction Bone is a unique natural inorganic-organic nanostructured composite composed of inorganic phase (mainly hydroxyapatite [HAp, Ca10(PO4)6(OH)2]) and organic phase (mainly collagen fibrils), with a hierarchical structure ranging from nanoscale to macroscale [1,2,3,4,5].
The degree of crosslinking of biopolymer-based hydrogels determines their mechanical properties, network structure, pore size, stability and biodegradation rate of the hydrogel [47,49,50].
