The Continuum Fallacy in Moral Philosophy

open access: yesTheoria, Volume 92, Issue 1, February 2026.
ABSTRACT ‘Spectrum arguments’ or ‘continuum arguments’ in moral philosophy are sometimes invalid because they commit a particular fallacy I call the ‘Continuum Fallacy’. An important example is an argument in population ethics described by Derek Parfit, which purports to derive a conclusion that he and others find repugnant on the basis of a weak and ...

Study on the equilibrium and kinetics of nickel (II) adsorption on cellulose from peanut shell modified with chitosan

open access: yesVietnam Journal of Science, Technology and Engineering
In this study, cellulose was produced by activating peanut shells with 5% NaOH as an alkaline agent and bleaching with 5 wt.% H2O2. Before being modified with chitosan, the cellulose was slightly oxidized with ammonium persulfate to introduce carboxyl ...

Bioremediation of Crystal Violet Dye Using Sapindus mukorossi Functionalized Iron‐Oxide Nanoparticles From Coprecipitation Method

open access: yesAsia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.
ABSTRACT The textile industry is a water‐intensive industry that disrupts aquatic ecosystems by releasing recalcitrant chemicals like crystal violet (CV) dye characterized by its carcinogenic and mutagenic nature. Ethanolic extract of saponin‐rich Sapindus mukorossi was employed in the synthesis of biogenic iron oxide nanoparticles (IONP).

Eggshell‐Based Biochar for Superior Adsorption of Crystal Violet Dye and Fluoride From Wastewater

open access: yesAsia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.
ABSTRACT Present study investigates the efficiency of eggshell biochar as a low‐cost and ecofriendly adsorbent for the simultaneous removal of fluoride ions and crystal violet (CV) dye from wastewater. The eggshell waste was pyrolyzed to produce biochar, which was thoroughly characterized and subsequently employed for contaminant adsorption.

Stable modification of relative curves

open access: yes, 2009
We generalize theorems of Deligne-Mumford and de Jong on semi-stable modifications of families of proper curves. The main result states that after a generically \'etale alteration of the base any (not necessarily proper) family of multipointed curves ...
