The Application of Hydrochar Composite Briquettes for Sustainable Slag Foaming in the Electric Arc Furnace Process

open access: yessteel research international, EarlyView.
Hydrochar‐mill‐scale briquettes with varying C/O molar ratios (0.07–0.90) have been tested at 1650 °C to evaluate their slag foaming performance for electric arc furnace application. All seven briquette recipes developed succeed in promoting slag foaming.

Incremental upper bound modeling of concrete failures in timber‐concrete notched connections

open access: yesStructural Concrete, EarlyView.
Abstract This paper introduces a novel theoretical framework for developing incremental upper bound solutions, which is applied to predict the response of two local concrete failures in timber‐concrete composite (TCC) decks with notched connections. The new approach enables a prediction of the capacity at the onset of failure as well as the entire post‐

MICROSTRUCTURAL AND PHYSICAL ASPECTS OF HEAT TREATED WOOD. PART 1. SOFTWOODS

open access: yesMaderas: Ciencia y Tecnología, 2006
Heat treatment of wood is an effective method to improve the dimensional stability and durability against biodegradation. Optimisation of a two-stage heat treatment process at relatively mild conditions (

Monitoring wildlife using long‐endurance solar‐electric UAVs

open access: yesWildlife Biology, EarlyView.
This report discusses the effectiveness of using small solar‐electric UAV (uncrewed aerial vehicles) for aerial wildlife monitoring. We review four years of aerial wildlife monitoring missions using a 5.5‐m wingspan, solar‐electric UAV that was equipped with a gimballed IR/RGB camera.

Effects of Morphological Age and Indole-3-Butyric Acid Concentration on Rooting of Selected Robusta Coffee Varieties

open access: yesCoffee and Cocoa Research Journal
In response to the outbreak of Coffee Wilt Disease (CWD) which wiped out almost 50% of Robusta coffee in Uganda, the National Coffee Research Institute (NaCORI) released 10 varieties (KR1-10) which are resistant to the disease. These varieties are being

Electrical Breakdown Analysis of Emerging Oil–Paper Insulation Systems

open access: yesHigh Voltage, EarlyView.
ABSTRACT This investigation addresses the effect of particulate additives on the electrical breakdown strength of the oil impregnated insulation paper system. The morphological complexity is addressed by converting data from scanning electron microscope images to a data set suitable for numerical simulation analysis. Then, by using the conventional oil‐

Orthogonal cutting forces in juvenile and mature Pinus taeda wood Forças de corte ortogonal na madeira juvenil e adulta de Pinus taeda

open access: yesScientia Agricola, 2005
The distinct characteristics of juvenile and mature woods, which are observed particularly in softwoods, have an influence on processing due to their different mechanical resistance properties in relation to cutting operations.

FRP-to-Softwood Joints: Experimental Investigation [PDF]

open access: yes, 2011
A proper understanding of the interfacial behaviour between timber and bonded fibre-reinforced polymer (FRP) composites will assist in the rational and optimal design of FRP strengthening works for timber structures. To enhance this understanding, a series of single-lap FRP-to-timber joint shear tests are reported herein in which the strength of the ...

Mechanical Properties and Quantitative Analytical Modelling of Micro/Nanocellulose Co‐Modified Insulating Papers With Different Aspect Ratios

open access: yesHigh Voltage, EarlyView.
ABSTRACT The incorporation of nanocellulose‐doped insulating paper into the material composition of a given structure has been demonstrated to enhance the material’s mechanical properties and retard the development of cracks. However, the effects of different length‐to‐diameter ratios of nanocellulose are different.
