The increasing levels of CO2 in the atmosphere are indicated as a major contributor to the enhanced greenhouse effect. There are several options to reduce these levels and the Carbon Capture and Storage (CCS) is identified as an effective way to decrease the concentration of this gas. In this work, it is present the i…
The steel production through Electric Arc Furnaces (EAF) generates approximately 15% to 20% of Electric Arc Furnace Dust (EAFD). This waste is considered dangerous due to the presence of metals as lead and cadmium that leach in contact with water. Because of this, the EAFD recycling becomes an alternative to diminish…
This work presents the modeling by the finite element method of the first cold rolling pass of a four-high mill at the CSN steel plant. For this purpose, a two dimensional model is proposed considering the work-roll as a rigid surface together with the assumptions of plane-strain state for the strip and material isotr…
Reinforced concrete is the most widely used construction material in the world. The combination of high compressive strength, afforded by concrete and, and the excellent mechanical properties that characterise steel make it an ideal composite for all manner of structures. One of the main weaknesses of this material, h…
The steel demand for fine applications have increased considerably in the last years, and the criteria for its production are even stricter, mainly in relation to the residual elements content and cleanness required. In relation to the steel cleanness, the main problem faced is the control of the amount and morphology…
Austenitic stainless steels wires are widely used in the final stages of orthodontic treatment. The objective of this paper is to study the process of conformation of rectangular wires from round wires commercial austenitic stainless steel AISI 304 by the process of cold rolling. The wire quality is evaluated by means…

ARGET (activators regenerated by electron transfer) ATRP (atom transfer radical polymerization) has been successfully performed (in flasks fitted with rubber septa without the need for use of Schlenk line) in the presence of limited amount of air and with a very small (370 ppm) amount of copper catalyst together with…
The occupational risk management model in case of the machine workshop is offered. The model is aimed at minimizing the potential negative factors effect of an operating environment on the workers, and, as consequence, the reduction of industrial injuries and occupational diseases. The generalized quantitative data of…
A whole complex of factors that may facilitate the effective training organization in the nonstate economic university is proved. In this case, each of the mentioned factors is regarded as a conceptual idea developing in the accordance with the common concept of the nonstate educational institution of the higher vocat…
Long-term change of the solonetzic salted chestnut soil complex of dry steppe after their agrotechnical improvement with a new facility of rotor plowing and mixing of illuvial and lower layers of soil is studied. Some technical parameters of the devices for soil-meliorative rotor-milling processing are discussed. More…
Various production methods are realized on the milling and drilling machines. A general approach to the model construction for the vibroacoustic dynamics of the oscillating system “spindle unit — cutting tool” is presented. On the pattern millers, boring and drilling are performed apart from the customary milling. Con…
As part of the plane strain, the problem on steady oscillations of the inhomogeneous through-thickness isotropic poroelastic layer with voids is considered. The layer bottom is connected with the perfectly rigid foundation, the oscillations are caused by the surface stress on the top face. Under the known inhomogeneit…
Tumbling drums are widely applied in various mechanical engineering branches. The basic deficiency of such technological machines is high intensity of the sound radiation. In modern drums, quiet drives are applied. In practice, the excess of the sanitary noise code is created by the sound radiation of the drum body un…
The statement of the axisymmetric consolidation problem for a porous, non-homogeneous in-depth half-space, and the construction of the fundamental solution to defining the displacement fields, strains, stresses, and pore pressure under the given boundary conditions are considered. The solution to the equations describ…
The operational and industry characteristics of the creation and development of the innovation process in the agribusiness are defined. The situation in this field is described as rather acute. To a large extent, it is caused by the transition deformations. The innovation process is considered by the author as a relat…
The theoretical investigation of the noise and vibration of the rail as a line limited distance elastically mounted source is resulted. When installing the rail on sleepers, it is presented as a system of two-point sources simultaneously radiating the sound energy, and every section of the rail between the sleepers –…
To reduce secondary processing such as sanding or chemical etching in the manufacture of composite structures, we present an in-mold surface preparation process using imprint lithography on carbon/epoxy composite adhesive joints. In the proposed in-mold process, microstructures are designed and fabricated on the surfa…
The design of the shock-vibrating finish machining with a ball-and-rod reinforcer (BRR) is considered. The essence of the method and the tool design are described. The effective application domains for the ball-and-rod reinforcer are offered. It is important to note that such processing can be used under the local har…
The construction and practical application issues of the software shell for the development and implementation of the rating assessment coefficient methods of objects (engineering, organizational, etc.) are considered. The given shell is designed for those users who wish to develop and enrich the computer coefficient…
