Economic Valuation Of Non-Timber Forest Products (NTFPs)

open access: yes
The paper reviewed the methods in use for the economic valuation of Non-timber forest products. In the main, three methods are used. They are direct market price, indirect market price and non-market estimates.

Additive Manufacturing of Continuous Fibre Reinforced Composites: Process, Characterisation, Modelling, and Sustainability

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing provides precise control over the placement of continuous fibres within polymer matrices, enabling customised mechanical performance in composite components. This article explores processing strategies, mechanical testing, and modelling approaches for additive manufactured continuous fibre‐reinforced composites.

Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

open access: yesAdvanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

open access: yesAdvanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Total Economic Values for Coastal and Marine Wildlife: Specification, Validity and Valuation Issues

open access: yes
Benefit-cost analysis of coastal and marine wildlife management programs requires that economic benefits be monetized for comparison with the costs of preservation.

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

open access: yesAdvanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

ECONOMIC VALUATION OF SOME WETLAND OUTPUTS OF MUD LAKE, MINNESOTA-SOUTH DAKOTA

open access: yes
The objective of this study was to estimate some economic values of Mud Lake, a managed, lacustrine wetland on the Minnesota-South Dakota border. Several outputs of Mud Lake were identified and an economic value was estimated for each.

Economic valuation of wetlands.

open access: yesJournal of environmental biology, 2006
This paper with case studies discusses the valuation of ecosystems considering the direct, indirect and existence benefits. The economic valuation of wetlands helps to understand the constituent's functions and benefits and this exercise could act as a catalyst for wetland conservation.
