This paper reports on a study of the corrosion levels in steel bars embedded in mortars made with a blend of Portland cement and (0-20%) spent fluid catalytic cracking catalyst residue (FC3R), with a variable (0.3-0.7) water/binder (w/b) ratio. The specimens were stored in the following conditions: relative humidity o…

The effect of blending short and long chains (bimodality) silicone prepolymer, in the presence of a filler (17.2 and 30.2% w/w) on tensile properties such as ultimate tensile strength (UTS), percent elongation at break (% Eb), 100% modulus and elastic modulus has been investigated. The content of short chain prepolyme…
The concept of homogeneous structures which realize principles of generating and expanded programming is introduced. Homogeneous structures are considered as the configuration reference point of the program project defining a process direction of division into modules and program structurization. Same examples of homo…
On the basis of linear control equation the inspectability property of determined dynamic systems over finite fields has been offered. Connection between inspectability and fundamental property of controllability of system is established. The synthesis example of the inspectable determined dynamic system over finite f…
The modeling done under the programme «DISK-REVERSE» allows to build the diagrams of dependence of the basic digital output parameters of the disk from the factors characterizing a place of giving, an angle of an inclination and direction of the disk rotation. The given digital output characteristics for work of the d…
We have employed Soft and Hard X-ray Resonant Magnetic Scattering and Polarised Neutron Diffraction to study the magnetic interface and the bulk antiferromagnetic domain state of the archetypal epitaxial Ni$_{81}$Fe$_{19}$(111)/CoO(111) exchange biased bilayer. The combination of these scattering tools provides unprec…
The defects found in the methods of the ABSAEA on the designation of the energetic parameters of the engine in the conditions of exploitation are represented and analyzed in the article. On the basis of the given analysis the improvements of the methods and devices of investigations of the engines with the turboblower…
The method and the results of the experimental investigation is expounded, which allow to set the direction of the resultants of resistance, influencing the seed, caught by the sucking hole of the vacuum sowing apparatus of the exact drill. The data can be used in theoretical calculation of the parameters and the work…
The model of process of decrease of pollution of the air environment, and also technique and results of experimental researches of efficiency of process of clearing of air for jetfraction chambers is resulted.
The system of theoretical models past experimental check is developed. The given models can be used for increase of efficiency of strengthening processing in fraction at a stage of technological designing
Increasing the accuracy and high acting of positioning for technological machines and their mechanisms is of great importance. It is achieved by inventing and modification of hydro-mechanical devises with hydraulic connecting lines. In this statement the positioning process of such devises is modeling, relationships b…
The methodology of modeling and optimization of vibrating protection systems of a workplace of the operator of a knock-out lattice for branch by a vibrating method of a forming mix in foundry manufacture is considered.
Results of experimental researches in cabins of bridge cranes are resulted. Influence of sources on formation of a sound field in cabins is revealed.
The basic stages of a complex development direction of a science and practice of powder metallurgy as method of information-analytical representation of its basic aspects are presented. The basic algorithm of carrying out of operations and the scheme of the decision of tasks in view on object with some number of unkno…
In the work we study a mathematical model about control of investments distribution, when the technological change is taken into consideration as an increasing elasticity coefficient on the capital factor. There is proposed a solution algorithm to solve respective optimization control problem, where the investment fun…
In this study, the strength and erosive characteristics of CaCO3 filled unsaturated polyester/glass fiber (UPR/GFR) composite are evaluated. Samples of UPR with 40, 50 and 60 wt% content of CaCO3 and different CaCO3 particle sizes of 1, 2, 3, 5 and 10 micron were prepared and tested under tensile loading, indentation…
Acrylonitrile-butadiene rubber (NBR) and blends of poly(3-thiopheneacetic acid)/ acrylonitrile-butadiene rubber, P3TAA/NBR, were fabricated, and the electrorheological properties, dielectric, and electrical conductivities were investigated . The electrorheological properties were determined under an oscillatory shear…
