Introduction: The relationship between elevated level of gas and particulate pollutants with increased mortality resulting from cardiovascular and respiratory diseases has been presented in epidemiological studies. Although the principal mechanisms of diseases are still unknown, inflammatory and homeostatic processes have been known to be related to this issue. Accordingly, this study was condu...

Visual inspection of industrial products is used to determine the control quality for these products. This paper deals with the problem of visual inspection of ceramic tiles industry using Wavelet Transform. The third level the coefficients of two dimensions Haar Discrete Wavelet Transform (HDWT) is used in this paper to process the images and feature extraction. The proposed algorithm consists...

TEGO® Dispers products have historically proven themselves in numerous coating and printing ink formulations. However, new and challenging applications are constantly being presented, and the products must be able to satisfy the latest demands. Of these, the use of digital printing across a variety of substrates – especially textiles and ceramic tiles – has come into focus and taken priority wi...

During the past 25 years, there has been a lot of discussion regarding the preparation techniques used for porcelain veneers. Calamia and other early pioneers looked at veneers as a non-invasive, additive process and worked primarily with a nopreparation concept. Early on it was found that a little enamel preparation could help to enhance the esthetic outcome and improve the marginal fit. Later...

Dense (>98 th%) and homogeneous ceramic/metal composites were obtained by spark plasma sintering (SPS) using ZrO2 and lamellar metallic powders of tantalum or niobium (20 vol.%) as starting materials. The present study has demonstrated the unique and unpredicted simultaneous enhancement in toughness and strength with very high flaw tolerance of zirconia/Ta composites. In addition to their excel...

The gathering of clinical data on fractures of dental restorations through prospective clinical trials is a labor- and time-consuming enterprise. Here, we propose an unconventional approach for collecting large datasets, from which clinical information on indirect restorations can be retrospectively analyzed. The authors accessed the database of an industry-scale machining center in Germany and...

Large amounts of polluted water are often obtained from the chemical process industry, which require a mandatory treatment before being disposed of. Heavy metals are employed as homogeneous catalyst in numerous processes, so that recovering and/or recycling of those metals to the reaction unit is essential. In this study, ultrafiltration is presented as a useful technique to recover heavy metal...

Presently, the ferrites industry consumes large amounts of iron osides obtained by spray roasting of steel pickling liquors. The aim of this paper is to propose the synthesis of optimal iron osidcs by oxyprecipitation of steel pickling liquors in order to obtain Bahexafenite wit11 high magnetic properties using the ceramic process. As a raw material. i t was used sulphuric liqoors with iron con...

Engineering ceramics have been widely used in modern industry for their excellent physical and mechanical properties, and they are difficult to machine owing to their high hardness and brittleness. Electrical discharge machining (EDM) is the appropriate process for machining engineering ceramics provided they are electrically conducting. However, the electrical resistivity of the popular engine...
