The effect of the laser shock processing on Pellet Traveling Grate surface fatigue crack growth performance were investigated from the theory of the fracture mechanics.A stress formula was set up to indicate the function of the residual stress on fatigue life. The effect of the compressive stresses was deemed responsi…
The theoretical effect of barium on calcite crystal growth is widely discussed and investigated. This paper provides a broad analysis of the effect of barium on calcium carbonate scale using a dynamic scale loop (DSL). With a DSL, it is possible to simulate conditions that can be found in oil/gas pipelines in actual p…
This paper will demonstrate that a broad disciplined approach to monitoring and inspection programs is required in order to manage the impact of gradual changes in process conditions on operating facilities. Where no process or integrity issues existed previously, gradual changes in the process can have a significant…
The corrosion damages significantly reduce the use-value and shorten the life time of various constructions. As a result of corrosion damages occur enormous costs, and sometimes major disasters which can lead to the material costs and also dangerous consequences for human life. With proper selection of structural mate…
Anisotropic conducting film (ACF)을 형성하기 위해서는 경화과정에 잠재성이 있어야만 하며, 보다 빠른 생산성을 갖기 위해서는 반응속도가 매우 높아야 한다. 이 연구에서는 여러 가지의 sulfonium 염들을 합성해서 epoxy 수지의 잠재성 경화제로 사용해 보았다. 이들 sulfonium 염들은 모두 우수한 잠재성을 보여 주었다. Differential scanning calorimetry (DSC)를 이용해서 이들의 경화거동을 살펴보았으며, $150^{\circ}C$ 에서의 경화 속도를 탐침법으로 측정하였다. A latent curing…
The paper describes synthesis method and colloid-chemical properties of novel α-amino acid based polyesters with controllable hydrophilic-lipophillic balance. Glutamic acid and diols of different nature based polyesters were obtained via low-temperature activated polyesterefication. Such polymers are able to form mice…
The unique characteristic, Shape Memory Effect (SME), of Shape Memory Alloys (SMAs), is primarily investigated by researchers as an economical source of actuation supplemented by its simple operating principle, and elimination of moving parts. Depending upon whether the SMA wire is martensitic, in transition, or auste…
The paper deals with the methods of forming three-layer structures by layer condensation of nanoscale films Ni, Fe and V. Investigated the magnetoresistive properties of the samples as well as their dependence on annealing temperature and the thickness of nonmagnetic layer. The correlation of magnetoresistance effect…

The described method for analysis of misorientation distribution in terms of a specific grain-boundary surface has been used. It was found that this approach was effective for study of grain structure evolution during deformation, recrystallization and grain growth.
The paper deals with numerical and physical modelling aimed at optimisation of production technology and designing of manufacturing tools with use of finite-element method. For the topic of cold bulk forming a manufacture of pressed insert, used in industry as a component for damping system for passenger cars, was sim…
New composite membranes were manufactured by impregnating post-sulfonated poly(arylene ether sulfone)s containing perfluorocyclobutane (PFCB) groups into porous polytetrafluoroethylene (PTFE) films. Two kinds of post-sulfonated poly(arylene ether sulfone)s with two different monomer ratios (sulfonable biphenylene mono…
Hydroxyapatite (HA) is well known as a biocompatible and bioactive material. HA has been practically applied as bone graft materials in a range of medical and dental fields. In this study, two types of dense hydroxyapatite ceramics were prepared from natural bones and synthetic materials. The biocompatibility of HA ce…
The article is focused on the solution of heat penetration through the body of a chimney based on the measurements of output temperatures of flue gases coming out of a chimney and their dew point, in order to determine the minimum flue gas temperature at the bag filter inlet.
Amount of polymer waste increase every year and for this reason upgrading of this waste is a necessity. Nowadays waste disposal and incineration of polymers waste are the most frequently used methods which (i) did not allowed chemical and energy utilization and (ii) are not environmentally friendly. Pyrolysis and co-p…
The article deals with the forming of brake ribs of diffrent heights from various sheet-metal thicknesses to evaluate the required force with which the required holding force will be in correlation in the actual tool, thereby avoiding non-stamping of break ribs when clamping the blank holder at the start of the drawin…
Flat sheet membranes were prepared with polysulfone (PSF) by an immersion precipitation phase inversion method. Membranes were prepared with PSF/N-methylpyrrolidone (NMP)/polyvinylpyrrolidone (PVP)/phosphoric acid casting solution and water coagulant. By using the successive process of the vapor-induced phase inversio…
The aim of this work was to investigate the combustion and nanoparticle emission characteristics of premixed charge compression ignition (PCCI) combustion at various test conditions using a single cylinder common-rail diesel engine. In order to create the homogeneity of fuel-air mixture, the premixed fuel (gasoline) w…
The thickness and chemical composition of oxides on heat recovery steam generator tubes of combined cycle power plant were examined in order to evaluate the corrosion of the tubes. Tubes were removed from the plant after actual operations for 21,482, 42,552 and 56,123 hours respectively. Thickness and growth rate of t…
