This means that two parameters of fiber diameter and drug ratio affected the releasing behavior of composite structures.
By increasing the ratio of the drug to the polymer structure continuously released the drug provided, but mechanical properties of the structure weakened.[9].

According to the authors [2] the structure of (Ga0.6In0.4)2Se3 (γ2-phase) with cw/aw=1.633 is called the ideal defect wurtzite structure, meanwhile, the structure of (Ga0.4In0.6)2Se3 (γ1-phase) with cw/aw=1.565 is called the layered defect wurtzite structure.
The crystal structure of the obtained crystals have been examined by XRD (Fig. 2) using PDWin-2 software package.
Both samples are of the hexagonal structures (S.G.
This is related to the decrease of the structure disorder due to healing of the crystal defects which formed the energy levels within the band gap of the semiconductor.
The investigation of the optical absorption spectra showed high structure disorder of the crystals which become close to the class of the amorphous materials.

Fluorite occurs as half self-columnar and self-columnar structure or fractal columnar structure.
Fluorite minerals are closely associated with each other or together with quartz constituting micro granular mosaic structure, granite metacryst mosaic structure.
Sometimes, single fluorite is closely associated in the form of vein structure, recrystallization, and constituting granular structure
By this means, extra value is added and stock of tailings is greatly reduced. 2 Efficient floatation reagent modification In order to improve collecting ability and low-temperature properties, we try to compare the structure of oleic acid ( a kind of fluorite flotation collector) with new chemical compound by using of computer-aided design drawing software(CAD)[3,4], medicinal chemistry and drug molecular structure design theory, thus providing efficient floatation reagent for fluorite tailing and improving its quality.
By this means, we could identify the molecular structure, relative stability and their affinity each other.

Based on the determined mathematical model, a temperature control structure which uses the Internal Model Control strategy is proposed.
The other intermediary signals which occur in the structure working are notated with ISi(s), where i {1, 2, 3, 4, 5, 6}.
The structure resulting through the implementation of the three equations which describe the heating process work The proposed temperature control structure The proposed control structure, based on the Internal Model Control (IMC) strategy used to control the heating process is presented in Fig. 4.
The proposed temperature control structure based on the IMC strategy The fixed part of the control system contains the actuator A (thermal resistance and its supply device), the technological heating process THP (modeled using the structure from Fig. 3) and temperature transducer TT (thermocouple).

The peculiarity of alkali-activated slag cements (further, AASC’s) is increased proper deformations, which can cause increased cracking and reduced durability of structure.
The fundamentals of general mineralogy and chemistry of cement give some explanations about possibility of the mentioned compounds to influence the structure formation of cement systems, namely about the isomorphism with replacing of silicate or aluminate anion, the ability to form solid solutions or additional crystalline formations (eg hydrated calcium sulfosilicate (Ca[Si(OH)6]2∙(SO4)3∙24H2O), calcium chloride hydrate (C3A∙CaCl2∙H2O or C3A∙3CaCl2∙3H2O), calcium fluoride (CaF2), calcium  hydroxylapatite (Ca10(PO4)6(OH)2), calcium hydronitroaluminate (3CaO∙A12O3∙Ca(NO3)2∙10H2O) etc., which affect the proper deformations [20, 21].
The above results allows predicting the effective manage AASC proper deformations by interference in structure using complex additives, co-acting on crystallization processes, formation of porous structure and morphology of hydrated phases.
