Two vegetable wastes, cork bark and grape stalks, were investigated for the removal of methylene blue from aqueous solution. The effects of contact time, dye concentration, pH, and temperature on sorption were studied relative to adsorption on a commercially-activated carbon. The highest adsorption yield was obtained within the pH range 5 to 10 for grape stalks and 7 to 10 for cork bark. The so...

Natural cork enclosures, due to their cell structure, composition, and low moisture are fairly transparent to terahertz (THz) and millimeter waves enabling nondestructive evaluation of the cork's surface and interior. It is shown that the attenuation coefficient of the defect-free cork can be modeled with a Mie scattering model in the weakly scattering limit. Contrast in the THz images is a res...

Background Cork oak (Quercus suber) is a long-living species of the Fagaceae family that highly contributes for the economy of several countries such as Portugal. It is the only plant species with a phellogen capable of a sustainable production of cork with properties suited for industry applications. Phellogen, or cork cambium, usually initiates in the subepidermis and differentiates during th...

We propose a new uniform framework of Compact Rational Krylov (CORK) methods for solving large-scale nonlinear eigenvalue problems: A(λ)x = 0. For many years, linearizations are used for solving polynomial and rational eigenvalue problems. On the other hand, for the general nonlinear case, A(λ) can first be approximated by a (rational) matrix polynomial and then a convenient linearization is us...

in order to know the environmental behaviour of toxic pollutants it is fundamental to understandthe role of chemical components of a material on sorption of such pollutants.in this study, the sorption of amix of polycyclic aromatic hydrocarbons (pahs) by cork fractions (i.e. raw cork (cf), free extractive cork(fef) and nonsaponifiable (desf)) has been investigated to better understand the role ...

PURPOSE To analyze the anatomic and functional consequences of wine-cork injury to the eye in relation to the patient's age and the type of cork and wine. METHODS We retrospectively studied 13 patients, six women and seven men, presenting to our department with bottle-cork injury to the eye between January 1999 and June 2001. RESULTS All patients presented with closed-globe injury according...

Cork oak (Quercus suber) forests are acknowledged for their biodiversity and economic (mainly cork production) values. WildWres are one of the main threats contributing to cork oak decline in the Mediterranean Basin, and one major question that managers face after Wre in cork oak stands is whether the burned trees should be coppiced or not. This decision can be based on the degree of expected c...
