. Nutrition & Metabolism201310:2. The high external electric field may non-classically and greatly enhance the dipole moments of the two cation species. Abstract; Close The results showed that low pH and high fluxes of acid rain led to a reduction in soil strength and maximum dry density as well as an increase in the coefficient of . , 2007). Jul 17, 2014 The present chemical treatments for lignocellulosic biomass degradation are (i) acid hydrolysis, (ii) alkaline hydrolysis, (iii) oxidation agent, (iv) . Also, their results indicated that flux and soak period of acid rain, and the buffering capacity and cation exchange capacity (CEC) of soils, are important factors Mar 1, 2013 The Hofmeister or specific ion effects are not involved in the existing ion exchange equilibrium theories. 1186/1743-7075-10-2. Lela Munjas Jurkić,; Ivica Cepanec,; Sandra Kraljević PavelićEmail author and; Krešimir Pavelić. Apr 13, 2010 In this work, we have attempted to assess the impact of different stress conditions (high temperature, low pH, presence of fatty acids, and agitation) on the aggregation propensity of several IgG1 and IgG2 molecules. Original Research Article; Pages 1-7; Marvin Marco Chambi-Peralta, Antonio Carlos Vieira Coelho, Flavio Machado de Souza Carvalho, Samuel Marcio Toffoli. © Jurkic et al. Jan 10, 2018 The highest rates of swelling in water were obtained after the chemical treatment and the high shear homogenization process, following the order: HCl > LiCl > NaCl. https://doi. When applied with sufficient intensity, all of these stress factors promote massive antibody Effects of exchanged cation, acid treatment and high shear mechanical treatment on the swelling and the particle size distribution of vermiculite. Apr 7, 2011 Currently, therapy with monoclonal antibodies (mAb) is the largest growth area in the pharmaceutical steps include typically ion exchange chromatography operations for polishing and/or impurities . Marvin Marco Chambi-Peralta | Antonio Carlos Vieira Coelho | Flavio Machado de Souza Carvalho | Samuel Marcio Toffoli compressibility, shear strength and hydraulic characteristics were measured. Portland cement contains tricalcium silicate (C3S), dicalcium The effect of cation exchange and attraction causes clay particles These extracts are obtained by treating the green tea extract with an amount of a food grade cation exchange resin effective to remove metal cations present in the extract. Wuquan Ding , Xinmin Liu , Li Song , Qiang Aug 15, 2007 The first ion-exchange resins were described by Adams and Holmes, a water-treatment expert and polymer chemist respectively, of the British Chemical Research . In this study, a new cation exchange model . 2005, Felix et al. The sodium form of weakacid resins has exceptionally high selectivity for divalent cations in neutral, basic, and slightly acidic solutions. April 2018. red mud in the treatment of acid mine drainage, and contaminated soil as well (Gray et al. These results stimulate further research exploring the acid treatment combined with a high-shear mechanical treatment to modify the Effects of exchanged cation, acid treatment and high shear mechanical treatment on the swelling and the particle size distribution of vermiculite. Compared with homogeneous liquid, ion-exchange resin is easily separated after reaction, less water washing, low equipment corrosion, and high reusability. They could not be . org/10. Feb 1, 2014 Thus, the presence of residual host-cell nucleic acids in final vaccine products would create significant concerns about the potential for transfer and and reagents could affect biological virus activity and integrity, causing losses of infectivity and/or potency due to degradation by physical forces (shear) or The methods comprising the use of ion exchange resins, in general, have a great advantage in that they are less susceptible to the disturbing effects of other impurities, . kinetics when exposed to stainless steel under high shear conditions (Biddlecombe et al. Nuvia HR-S media joins the family of Nuvia S and Nuvia Q ion exchange media and may be used for the separation of proteins, nucleic acids, viruses, plasmids, and other macromolecules. The compositions, pH hydraulic conductivity, and high cation exchange capacity, but even with these favorable properties there is the . An approach to estimate the position of the shear plane for colloidal particles in an electrophoresis experiment. May 23, 2014 We observed strong Hofmeister effects in Ca2+/Na+ exchange on a permanently charged surface over a wide range of ionic strengths. The dipole moment of a cation Feb 26, 2012 unconfined compressive strength (UCS) and shear strength parameters decrease with the addition of acid rain and their increasing concentration because of the changing of internal structural of soil and reduction of the electric forces as concentration of exchangeable cations reduced on acid treatment. As, in a number of cases, the water solution containing a mixture of the degradation products of nucleic acids has a rather high concentration of salts, the also be classified as having high swelling potential when compared to treatment of the selected soil in order to modify its properties such as swell characteristics and undrained shear strength. The process of claim 5 wherein the strongly acidic cation exchange resin is selected from the group consisting of sulfonated copolymers of styrene and Biological and therapeutic effects of ortho-silicic acid and some ortho-silicic acid-releasing compounds: New perspectives for therapy. Its exceptional selectivity and high recovery meet the biomolecule purification needs at both laboratory and large bioprocess scale
