Zagros Restoration: Smart Choices for Oak Forests

Land Degradation &Development, EarlyView.
ABSTRACT Widespread forest degradation across the northern Zagros region of Iran driven by both human activity and natural processes has created an urgent need for targeted afforestation and forest enrichment strategies. Hence, the aim of this study was identifying the most suitable native tree and shrub species for restoring degraded forest areas in ...

Application of Potentiometric and Electrophoretic Measurements to Evaluate the Reversibility of Adsorption of Divalent Ions from a Solution on Titanium Dioxide

Molecules
The adsorption of divalent ions on metal oxides is controlled by the pH of a solution. It is commonly assumed that this is a reversible process for pH changes. However, there are reports that the sorption of ions on oxides may not be reversible.

A computer‐controlled potentiometric/spectrophotometric titrator [PDF]

Journal of Analytical Methods in Chemistry, 1988
A laboratory computer controlled potentiometric titrator interfaced to a diode array spectrophotometer is described. The titrator consists of widely used, commercially available components; therefore, major attention is given to modes of interconnection and software implementation in data format and system control.

Annual–Perennial Forage Mixtures Improve Forage Productivity and Soil Quality in Patchily Degraded Cultivated Pastures Under Grazing Management

Land Degradation &Development, EarlyView.
ABSTRACT Patchy degradation of cultivated pastures under long‐term grazing is a serious issue limiting grassland productivity. The use of annual and perennial legume–grass mixtures, which offer complementary functional advantages, may provide a practical reseeding‐based approach for improving patchily degraded cultivated pastures; however, limited ...

Mechanical, rheological, and durability performances of GGBS‐based concrete for potential application to prestressed structures

Structural Concrete, EarlyView.
Abstract Ground granulated blast‐furnace slag (GGBS) is a widely used clinker substitute in concrete, recognized for its potential to significantly reduce environmental impacts. However, its application in prestressed concrete remains limited in several countries, mainly due to concerns regarding early‐age mechanical performance and long‐term ...

Cyanogenic Compounds, Physicochemical Parameters and Metals in Water From Cassava Processing Areas: A Study in the Brazilian Amazon, Using Multivariate Analysis

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the water quality of artesian wells and effluents generated in cassava processing in a rural area of Bragança, Pará, with emphasis on physicochemical parameters, multielement composition, and cyanogenic compounds. The well water presented specific nonconformities, highlighting pH values below the recommended level and high
