Fumaric acid production from fermented oil palm empty fruit bunches using fungal isolate K20: a comparison between free and immobilized cells [PDF]

open access: yesPeerJ
This study investigated the potential of using steam-exploded oil palm empty fruit bunches (EFB) as a renewable feedstock for producing fumaric acid (FA), a food additive widely used for flavor and preservation, through a separate hydrolysis and ...

Cost objective PLM and CE [PDF]

open access: yes
Concurrent engineering taking into account product life-cycle factors seems to be one of the industrial challenges of the next years. Cost estimation and management are two main strategic tasks that imply the possibility of managing costs at the earliest

Product differentiation and intra-industrial trade: Quantitative assessment in the case of Tunisia [PDF]

open access: yes, 2007
In this article we try to analyze the extend of product differentiation in the Tunisian’s context, by relying on an investigation drived at a sufficiently disaggregated level of sectors.

Effect of Laser Deoxidation on Adhesive‐Bonded Aluminum in an Oxygen‐Free Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates laser ablation of aluminum under oxygen‐free conditions. The goal is to produce oxide‐free substrates that enable improved adhesive bonding with epoxy. Optimized laser parameters (90% overlap, 300 µJ) combined with oxide‐free substrates result in the highest tensile strength of the adhesive bond.

Demonstration of Power-over-Fiber with Watts of Output Power Capabilities over Kilometers or at Cryogenic Temperatures

open access: yesPhotonics
We demonstrate the use of laser diodes and multijunction photovoltaic power converters to efficiently deliver watts of electrical power for long-distance or cryogenic applications. Transmission through single-mode and multi-mode fibers at the wavelengths

Biological modification of functional properties of orange-fleshed sweet potato flour by spontaneous fermentation and its possible utilization [PDF]

open access: yesBIO Web of Conferences
This study evaluated some functional properties of the orange-fleshed sweet potato flour modified by spontaneous fermentation at different times. This information can further be used to assess its potential application in food processing. Under anaerobic

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

open access: yesAdvanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

Isolation of marine bacteria with potential for polyhydroxyalkanoate degradation and optimization for enzyme production

open access: yesScientific Reports
Plastic materials are widely used because of their strength, light weight, durability, and environmental resistance. However, their decomposition rates are significantly slower than their typical lifespans.
