Potential for managing natural regeneration by family farmers in the Amazon: making the most of biodiversity [PDF]

open access: yes, 2019
Natural regeneration represents more than half of all tropical forests. Within the Brazilian Amazon, the area of regenerating forest increased by 70% between 2004 and 2014, currently occupying more than 17 million hectares.

Industrial water management by multiobjective optimization: from individual to collective solution through eco-industrial parks. [PDF]

open access: yes, 2012
Industrial water networks are designed in the first part by a multiobjective optimization strategy, where fresh water, regenerated water flow rates as well as the number of network connections (integer variables) are minimized.

Synthesis of a Novel Thermoresponsive S53P4 Bioactive Glass Extract–Poloxamer 407 Injectable Hydrogels: Assessment of Biocompatibility and Antimicrobial Properties

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates innovative thermoreversible hydrogels derived from S53P4 bioactive glass extracts to aid in the healing of infected diabetic foot wounds. These injectable gels, which gel at body temperature, release beneficial ions and remain stable over time.

Successional Patterns of Plant and Animal Diversity Under Contrasting Restoration Modes in Typical Coal-Mine Wastelands of Southwestern China

open access: yesDiversity
Ecological restoration of mine wastelands is central to biodiversity conservation and ecosystem recovery worldwide. However, the long-term ecological consequences of active restoration versus natural regeneration remain debated, particularly in ...

Fir-dominated forests in Bavaria, Germany [PDF]

open access: yes, 2005
The map of “Regional natural forest composition by main tree species” (WALENTOWSKI et al. 2001) depicts Bavaria as a region largely predominated by the European beech (Fagus sylvatica).

Al–Cu Composite Casting of Laser‐Deoxidized Copper: Bonding, Interfacial Chemistry, and Thermal Conductivity

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

Chemotropic guidance facilitates axonal regeneration and synapse formation after spinal cord injury. [PDF]

open access: yes, 2009
A principal objective of spinal cord injury (SCI) research is the restoration of axonal connectivity to denervated targets. We tested the hypothesis that chemotropic mechanisms would guide regenerating spinal cord axons to appropriate brainstem targets ...

Natural Bone‐Derived Ceramic Scaffolds Functionalized with Chitosan‐Gold, Chitosan‐Magnesium, and Chitosan‐Zinc for Enhanced Antibacterial Activity

open access: yesAdvanced Engineering Materials, EarlyView.
This study reports the development of antibacterial ceramic scaffolds derived from natural bovine bone. The bones were processed through sequential boiling and hydrogen peroxide treatment to remove organic matter, producing porous, mineral‐rich scaffolds.

Potential Irreversible Catastrophic Shifts of the Assimilative Capacity of the Environment [PDF]

open access: yes
Pollution accumulation may result in more or less severe losses of natural self-cleaning capacities. We study a polluting resource management problem submitted to a potential shift from a high to a low pollution self-regeneration regime be crossed some ...

Extensive spontaneous plasticity of corticospinal projections after primate spinal cord injury. [PDF]

open access: yes, 2010
Although axonal regeneration after CNS injury is limited, partial injury is frequently accompanied by extensive functional recovery. To investigate mechanisms underlying spontaneous recovery after incomplete spinal cord injury, we administered C7 spinal ...
