Materials and Methods During the operation, dimensional relations do not remain constant [1, 2, 3].
Internal factors are parameters that determine the operational properties of the mating surfaces: material of parts, lubricants, quality parameters of the surface layer etc.
The generative approach to the technology development involves the automatic synthesis of treatment strategies based on geometric configuration and technical requirements for parts, with information about the material, processing specifics and proposed control methods of the product.

Introduction Grain seeds: wheat, barley, oats, rice, maize, buckwheat, etc. which provide food for humans and animals, as well as the raw material of some industrial enterprises, have an average moisture content of freshly harvested grains ranging from 13% to 40%.
In order to remove the water from the drying process, drained through the tubes (48) and (44), a container is used made of a silica gel-type hygroscopic material (46) supported by a sheet metal base (45) fixed on a pair bracket-embedded blade transducers (47), (41) on which resistive tensometric resistors (42), (43) are placed bound in the semi-bridge and coupled to the tensometric bridge (24).
By using the automation, measuring and control devices of the process parameters with which the grain seeds and technical plant drying unit was equipped, very close or even identical values of the humidity and the drying temperature of some samples of wheat, maize and sunflower were obtained, which leads to the idea that such systems, redesigned and adapted to the requirements of industrial installations, can lead to corresponding energy consumption results, end-stage parameter values of the materials to be dried, and to the design of some machines with the possibility to adjust the highly flexible technological parameters.

The materials used in improving the new soil are abundant, such as the surface soil of rich cultivated land, fertilizers, organic wastes, green manures, nitrogen fixing plant and the culms of crops[3,4].
The design features of this structure are double base materials, simple variety of plaques, regularity in distribution and clear boundary.
The major technical essentials are: rational arrangement of the area ratio of water-abundant base material and drought-tended base material, three-dimensional spatial arrangement, and effective allocation of the passages such as roads and the system of irrigation.

Assessing the Impact of Corn-Ethanol Production on Global Corn Price Based on a VAR Model Lingxiao Wu 1, a, Junping Ji 1, 2, b and Xiaoming Ma 1, 2, c 1 Peking University Shenzhen Graduate School, Shenzhen, China, 518055 2 College of Environmental Sciences and Engineering, Peking University, Beijing, China, 100871 awulingxiao@sz.pku.edu.cn, bjackyjjp@gmail.com, cxmma@pku.edu.cn Keywords: fuel ethanol, corn price, VAR.
The fuel ethanol industry should turn to non-grain materials in the future to keep the global corn price steady and guarantee global food security, and it’s necessary for all fuel ethanol producers to take action.
Corn is the major raw material used in the US to produce fuel ethanol.
Since grain-based fuel ethanol industry should be restricted and reconsidered as the blind development will bring the problem of corn price increase and threaten global food security, turning to non-grain material will be the optimal direction for fuel ethanol industry’s future development.

In the rural environment of eastern Turkey, buildings are mostly built by the owner as masonry structures with materials that can be obtained locally.
The builder-owner uses low-strength materials such as adobe brick, clay brick, rubble stone, round timber logs, earth roof filling, and mud mortar; with the primary concern being cost, rather than seismic loads.
In the last decade, even though people in rural areas of the region began to use non-local materials, such as concrete and aluminium, they still build their units with structural faults due to a lack of knowledge [19,20].
The main reasons behind this result rely upon the structural faults in buildings and low quality materials used in constructions regardless to meeting the requirements in law.
