Functional Diversity and Oleaginous Potential of Fungal Strains From Hawaiian Soil Ecosystems

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Fungi represent an important but underexplored resource for microbial lipid production, including nutritionally valuable polyunsaturated fatty acids. Hawaiian soils, shaped by volcanic parent materials and strong environmental gradients, provide a unique setting for discovering functionally diverse fungal strains with distinct metabolic traits.

Analysis of Distribution Model of Matric Suction of Land Subsidence Caused by Foundation Pit Dewatering

open access: yesEngineering Transactions, 2015
By the soil matrix suction distribution under one-dimensional steady-state flow, soil permeability coefficient ks, infiltration intensity q and initial groundwater table factors that influence the matric suction of unsaturated soil were analyzed in this ...

From Material Tensions to Organizational Paradoxes: How Manufacturers Cope With the Limits of Circular Product Design

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular product design (CPD) is central to advancing the circular economy by enabling the narrowing, slowing, and closing of resource flows. Yet, its implementation remains persistently challenging for firms. Prior research has largely framed these challenges as discrete barriers, overlooking the structural contradictions embedded in CPD ...

Stability of 3D tunnel face under steady unsaturated seepage coupled multi-layer soil suction head distributions

open access: yesAlexandria Engineering Journal
This paper proposes a new discrete approach for analyzing tunnel face stability in stratified soils under unsaturated seepage conditions. Traditional methods have primarily focused on homogeneous soils, neglecting the spatial variability of unsaturated ...

Direct Shear Test of Unsaturated Soil [PDF]

open access: yes, 2017
The present study focuses on some tentative laboratory tests using a newly-constructed modified direct shear test apparatus. The single-stage and multistage direct shear tests were performed to determine the shear rate and test scheme of unsaturated ...

A lumped modelling framework for the epoxidation of vegetable oils and fatty acid methyl esters

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Epoxidized vegetable oils and fatty acid methyl esters are promising bio‐based alternatives to phthalates for plasticizer applications. Their synthesis typically involves the reaction of unsaturated double bonds with peracetic acid in a biphasic liquid–liquid system, where the simultaneous occurrence of reaction and phase partitioning makes ...
