La sociedad multicultural. Democracia y derechos
1997
En este artículo, el autor parte de un hecho sustancial: las sociedades multiculturales constituyen un fenómeno característico de nuestro tiempo. Es decir, en las sociedades actuales conviven códigos e identidades culturales diversos como consecuencia de diferencias étnicas, lingüísticas, religiosas o nacionales. En Europa, este fenómeno responde a la fragmentación de sociedades altamente homogéneas, a la crisis de consensos internos y del modelo del Estado social, a los flujos migratorios, etcétera. Ciertamente, la complejidad de las sociedades multiculturales plantea desafíos a la democracia: ¿cómo conciliar la unidad política con la diversidad social? El autor analiza el debate generado …
A supported titanium postmetallocene catalyst: Effect of selected conditions on ethylene polymerization
2011
Ethylene polymerization with a titanium complex [N,N-ethylenebis(3-methoxysalicylideneiminato)titanium dichloride] immobilized on the magnesium support with the formula MgCl2(THF)0.32(Et2AlCl)0.36 was studied. In particular, the effects of polymerization temperature, monomer pressure, and polymerization time on the activity of the catalyst and on the polyethylene properties (molecular weight and its distribution, melting point, crystallinity, and bulk density) were evaluated. The findings of investigations prove that the studied supported titanium catalyst is highly active in ethylene polymerization, and its activity increases with increasing temperature and monomer pressure. Moreover, stab…
Weathering of low-density polyethylene grafted with itaconic acid in laboratory tests
2011
Polyethylene grafted with itaconic acid was subjected to weathering under laboratory accelerated conditions. The course of the photo-oxidative degradation process of that material was studied by FTIR spectroscopy both through quantitative measurements of changes in absorbance values at selected wave numbers and through measurements of surface area values for absorption bands which were separated by means of deconvolution. The use of both those procedures of quantitative determinations resulted in a general conclusion that the oxidation process was initiated from the very first moment of irradiation, and it produced ketones, acids, esters (intramolecular and of acetate type), peracids, peres…
Analysis of a GC/MS Thermal Desorption System with Simultaneous Sniffing for Determination of Off-Odor Compounds and VOCs in Fumes Formed during Extr…
2001
A thermal desorption equipment introducing volatile organic compounds (VOCs) into the gas chromatographic/ mass spectrometric system (GC/MS) with simultaneous sniffing (SNIFF) is a suitable method for identifying the volatile organic off-odor compounds formed during the extrusion coating process of low-density polyethylene. Fumes emitted during the extrusion coating process of three different plastic materials were collected at two different temperatures (285 and 315 degrees C) from an outgoing pipe and near an extruder. The VOCs of fumes were analyzed by drawing a known volume of air through the adsorbent tube filled with a solid adsorbent (Tenax GR). The air samples were analyzed by using…
Some remarks on Hilbert's (Weak) Nullstellensatz
2011
Certain remarks are provided related to weak nullstellensatz exploiting some problems proposed in Fulton’s book entitled “An Introduction to Algebraic Geometry” and elementary notions of Functional Analysis.
Preparation of tungstophosphoric acid/cerium-doped NH2-UiO-66 Z-scheme photocatalyst: a new candidate for green photo-oxidation of dibenzothiophene a…
2021
International audience; The goal of this study was to introduce an effective visible-light induced photocatalytic system with a good ability for photocatalytic oxidative desulfurization (PODS) and denitrogenation (PODN) using molecular oxygen (O2) as an oxidant. In this regard, tungestophosphoric acid (PW12) was supported onto cerium-doped NH2-UiO-66 (PW12/Ce-NUiO-66) and employed for the photo-oxidation of dibenzothiophene (DBT) and quinoline (Qu). Herein, using cerium (Ce) as a “mediator” facilitated the separation of charge carriers, while NH2-UiO-66 remarkably enhanced the surface area with plentiful adsorption sites and shifted the adsorption edge of PW12to the visible region. The sum …
Fresh-Cut Mangoes: How to Increase Shelf Life by Using Neem Oil Edible Coating
2022
The mango is the most widely cultivated tropical fruit. Fresh-cut mango is very useful, but it is very perishable. The purpose of this study was to highlight the effects of neem oil on fresh-cut mango fruits kept for 9 days at 4 ± 1 °C and 80 ± 5% relative humidity. The neem plant (Azadirachta indica) has numerous antioxidant and antibacterial properties. Despite this, very few studies have been carried out on neem oil added to edible coatings (EC) to retard ripening processes. Two formulations were tested: EC1 (hydroxypropyl methylcellulose + CaCl2) and EC2 (hydroxypropyl methylcellulose + CaCl2 + neem oil), both compared with an untreated sample (control). Physicochemica…

Volfganga Velša dzirdes kultūras koncepts
2018
Volfganga Velša dzirdes kultūras jēdzienā ir ietverta metateorētiska Rietumu kultūras filozofijas kritika, apspriežot Rietumu filozofiskajā diskursā izveidojušās okulārcentriskās tendences. Abām maņām ir atšķirīgi fenomenoloģiskie apraksti: dzirde iesaistās pasaulē, uzklausa un ieklausās, nevis, kā to dara redze, objektivizē, distancējas un sniedz prioritāti subjektu-objektu attiecībām. Tā rezultātā, sākot ar senajiem grieķiem un kulminējot apgaismības laikmetā, redzes metaforas filozofijā ir veidojušas ne tikai Rietumu epistemoloģiskās, bet arī sociālās, kulturālās un ētiskās nostādnes. Atsacīšanos no redzes hegemonijas jeb okulārcentrisma mūsu filozofiskajā valodā Velšs uzskata par nepiec…
