Theoretical investigation of the adsorption of a binary mixture in a chromatographic column using the nonlinear frequency response technique
(Springer, New York, 2007)
The nonlinear frequency response of a chromatographic column for the adsorption of two dissolved components is analyzed using the concept of higher order frequency response functions (FRFs) which is based on the Volterra ...
Osmotic and activity coefficients of the {xZnCl(2)+(1-x)ZnSO4}(aq) system at 298.15 K
(Springer/Plenum Publishers, New York, 2007)
Isopiestic vapor pressure measurements were made for {xZnCl(2)+(1-x)ZnSO4}(aq) solutions with ZnCl2 molality fractions of x=(0,0.3062,0.5730,0.7969, and 1) at the temperature 298.15 K, using KCl(aq) as the reference standard. ...
Protection of probiotic microorganisms by microencapsulation
(Association of the Chemical Engineers of Serbia, 2007)
Probiotic bacteria are used in the production of fermented dairy foods, pharmaceutical products and health supplements. They play an important role in promoting and maintaining human health. In order, to produce health ...
Thermal, oxidative and radiation stability of polyimides. Part IV: Polyimides based on N-[4-benzoyl-2-(2,5-dioxo-2,5-dihydro-pyrrol-1-yl)-phenyl]-acetamide and different diamines
(Elsevier Sci Ltd, Oxford, 2007)
Polyimide resins were obtained from the reaction between N-[4-benzoyl-2-(2,5-dioxo-2,5-dihydro-pyrrol-1-yl)-phenyl]-acetamide and the following compounds with terminal amino groups: urea, 4-[(4-aminophenyl)sulfonyl] aniline, ...
Volumetric properties of the binary methanol plus chloroform and ternary methanol plus chloroform plus benzene mixtures at (288.15, 293.15, 298.15, 303.15, 308.15, and 313.15) K
(Amer Chemical Soc, Washington, 2007)
Densities rho of the ternary system of methanol + chloroform + benzene and binary mixture of methanol + chloroform have been measured at six temperatures (288.15, 293.15, 298.15, 303.15, 308.15, and 313.15) K and atmospheric ...
Direct hemp cellulose dissolution in N-Methylmorpoline-N-Oxide
(Taylor & Francis Inc, Philadelphia, 2007)
The increased production of bast fibres (especially hemp fibres) brought about an increase in the amount of waste, namely shive (hemp stalks) and short fibres. This waste presents a potential significant source of high ...
The effect of fermentation medium composition on lipase production by yeast Candida utilis / Uticaj sastava fermentacione podloge na prinos produkovanih lipaza pomoću kvasca Candida utilis
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2007)
In this work lipolytic activity of various microorganisms isolated from spoiled soybean oil was studied. Wild yeast strain identified as Candida utilis was chosen for the producing microorganism based on the activity shown ...
Carbon-13 substituent chemical shifts in N-1-p-substituted phenyl-5-methyl-4-carboxy uracils
(Elsevier Science Bv, Amsterdam, 2007)
The C-13 NMR chemical shifts of seven N-1-p-substituted phenyl-5-methyl-4-carboxy uracils have been measured in deuterated dimethyl sulfoxide (DMSO-d sigma). The correlation analysis for the substituent-induced chemical ...
Influence of composition of the magnetic composite coating on the performance of the optical fiber magnetic field sensing element
(Natl Inst Optoelectronics, Bucharest-Magurele, 2007)
The optical fiber magnetic sensing element (OFMSE) based on the optical fiber coated with composite coating polymer-magnetic powder has been already introduced in magnetic field sensing. In this research, the rapid quenched ...
Supercritical carbon dioxide extraction of sesquiterpenes from valerian root
(Elsevier Science Bv, Amsterdam, 2007)
Supercritical carbon dioxide extraction of sesquiterpenes from valerian root was investigated. Extractions from cultivar Arterner zuctung and two wild grown valerian subspecies were performed. The influence of extraction ...
