Optimization of coal flocculation with an anionic flocculant using a Box-Wilson statistical design method
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2014)In this study, the Box-Wilson statistical experimental design method was employed to evaluate suspension pH, salt (CaCl2·2H2O) concentration and anionic flocculant (A-150) amount in flocculation of coal. Response function ... -
Flocculation of fine particles in ceramic wastewater by using polymers
(Polish Mineral Engineering Society, 2014)The clarification of industrial wastewaters by solid-liquid separation techniques and the removal of suspended particles are the problems of growing environmental consciousness. However, there appears to be very limited ... -
The effects of ball types on breakage parameters of barite
(Polish Mineral Engineering Society, 2014)Spherical balls are the dominant media shape used in the tumbling mills. However spherical balls wear into nonspherical fragments as a result of breakage due to impact and different wearing mechanisms inside the mill. Thus ... -
The relationship between cement quality and separation cut size
(Polish Mineral Engineering Society, 2015)Cement is prepared by firing a mixture of raw materials, one of which is mainly composed of calcium carbonate and the other of aluminium silicate. The most familiar materials answering to this description are limestone and ... -
Hydrophobicity of galena with ovalbumin and dithiophosphinate in relation to its potential response
(Polish Mineral Engineering Society, 2018)This study was performed to elucidate the role of ovalbumin (OVA) on the hydrophobicity and potential response of galena in the presence of dithiophosphinate (DTPI). OVA was tested as environmentally friendly depressing ... -
The efficacy of nanoemulsion-based delivery to improve vitamin D absorption: comparison of in vitro and in vivo studies
(Wiley-VCH Verlag, 2018)SCOPE: Vitamin D (VD) is a fat-soluble vitamin that has a wide range of skeletal and non-skeletal functions. Although it can be synthesized through sun exposure and obtained from fortified foods, VD inadequacy is epidemic ... -
Fibrous polymer-grafted chitosan/clay composite beads as a carrier for immobilization of papain and its usability for mercury elimination
(Springer Verlag, 2016)Papain, which is an industrially important enzyme, has been immobilized on fibrous polymer-modified composite beads, namely poly(methacrylic acid)-grafted chitosan/clay. Characterization studies have been done using FTIR ... -
Evaluation of the effects of surface treatments on different dental ceramic structures
(2013)The surface treatments applied to porcelain materials can be different overglaze methods, chemical interactions and polishing techniques. The aims of these methods are the most durable restoration and the smoothest surface. ... -
Investigation of hole effects on the critical buckling load of laminated composite plates
(Institute of Metals Technology, 2016)In this study, the effects of the hole diameter on the buckling behavior of glass-fiber-reinforced, laminated composite rectangular plates were investigated both experimentally and numerically. As the test specimens, ... -
Synthesis and Characterization of Chitosan/Polyvinylpyrrolidone/Zeolite Composite by Solution Blending Method
(Springer New York LLC, 2014)Polymer/clay composites have been studied for several decades; in the study, polymer/zeolite composite beads have been prepared by a simple solution blending method using chitosan, polyvinylpyrrolidone and zeolite particles ... -
Affinity binding of proteins to the modified bacterial cellulose nanofibers
(Elsevier B.V., 2017)The potential of the modified bacterial cellulose (BC) nanofibers was determined bearing metal ion coordination interactions to enhance the protein adsorption and binding capacity. Thus, a household synthesized metal ... -
Protein depletion with bacterial cellulose nanofibers
(Elsevier B.V., 2018)In this study, we have reported a novel fabrication technique for human serum albumin (HSA) imprinted composite bacterial cellulose nanofibers (MIP-cBCNFs) used for the depletion of HSA selectively from artificial blood ... -
An artificial neural network model for the effects of chicken manure on ground water
(2012)In the areas where broiler industry is located, poultry manure from chicken farms could be a major source of ground water pollution, and this may have extensive effects particularly when the farms use nearby ground water ... -
