Following recent results 5] showing the importance of the fat shattering dimension in explaining the beneecial eeect of a large margin on generalization performance, the current paper investigates how the margin on a test example can be used to give greater certainty of correct classii-cation in the distribution independent model. The results show that even if the classiier does not classify al...

the aim of the present work was to investigate the ability of cocopeat to remove of lead (ii) from aqueous solutions. the effects of different parameters such as particle size, adsorbent dosage, ph, contact time, agitation speed and concentration on the removal process has been investigated. the maximum removal of lead ion (92.5%) took place in the ph range of 4 contact time in 30 minutes and i...

Acidification of foods with organic acids, either by fermentation or by intentional addition, is an important and common mechanism for controlling foodborne pathogens in a diversity of food products. The objective of this work was to study thermal inactivation of Listeria innocua, an acid tolerant microorganism, at 52.5, 60.0 and 65.0 degrees C, at different pH values (4.5, 6.0 and 7.5), using ...

Abstract Magnetic activated carbon (Fe 3 O 4 -AC) is made using Fe and as primary materials to adsorb Cr(VI) in simulated wastewater. The Response Surface Method (RSM) optimizes the experimental parameters (pH, temperature, initial solution concentration, dosage). impacts of various elements are explored determine ideal reaction conditions for maximum elimination. According data, interaction be...

Cell regulation of Ph(+)cell proliferation and differentiation has been studied ex vivo in various chronic myeloid leukemia (CML) patients. The regulation is provided by alternation of effective stages of proliferation and maturation with inhibition of Ph(+) cell proliferation by accumulating neutrophils under apoptosis blockage. The alternation of stages consists of switching stage 1 (effectiv...

the interaction of bovine serum albumin ( bsa) and egg albumin with water solublephthalocyanine, cobalt (ιι) 4, 4′ , 4′′, 4′′′- tetrasulfophthalocyanine ( cotspc) , has been studiedby the uv- vis method at ph 7.0 and five different temperatures 20, 25, 30, 35 and 40°c. theformation constants have been elucidated by using spectrophotometric titration and computersquad program data refinement. th...

The solute-solvent interactions of L-Cysteine and L-Methionine have been studied pH metrically in various concentrations (0.060.0% v/v) 1, 4-Dioxane-water mixture maintaining an ionic strength of 0.16 mol L-1 at ambient conditions. The protonation constants have been calculated with the computer program MINIQUAD75 and the best fit chemical models are selected based on statistical parameters. Li...

Siumimiary. A deamlinlase specific for 4-aminopyrinmidine nucleosi(les has been found in rye grass. Lolimn perennle. TI'he pH optimiium., temperature stability. Km valtues and specificity ws'as determined. A new and more accurate method for following the course of deamination is reported. This metho(d depends on the shift in maximumii absorbance wavelength of the mixtuire conltaiing the 4-an-in...

Four (57)Fe-labeled tetrachloroferrates(III) of organic cations (1-butyl-3-methylimidazolium, 1-allyl-3-methylimidazolium, 1-methyl-1-propylpyrrolidinium, tetraphenylphosphonium) were examined by temperature-dependent Mössbauer spectroscopy. The hyperfine and dynamic parameters of the iron(III) site were determined. Single crystal X-ray diffraction data of [Ph(4)P][FeCl(4)] were collected at fo...
