A Linear Time Algorithm for Drawing a Graph in 3 Pages within its Isotopy Class in 3-Space [PDF]

open access: yes, 2015
We consider undirected graphs up to an ambient isotopy in 3-space. Such a graph can be represented by a plane diagram or a Gauss code. We recognize in linear time if a Gauss code represents an actual graph in 3-space.

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Do Environmental Certifications Pay? A Bibliometric and Systematic Review of Environmental Management Systems and Eco‐Label Impacts

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates how environmental certifications—specifically, formal environmental management systems (EMSs) (ISO 14001, EMAS), and consumer‐facing eco‐labels—influence firm financial performance. Using a dual approach that includes a bibliometric review and a systematic analysis of key studies, we identify key trends, theoretical ...

More Than 10 Years on: Does a State‐of‐the‐Art Review and Synthesis Offer New Frameworks to Guide Future Design for Remanufacturing Research?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT There is strong evidence that design for remanufacturing (DfRem) can reduce initial‐design carbon emissions by up to 30%, and that product design can critically affect remanufacturing feasibility, yet academic adoption of DfRem remains limited.

Global nonlinear optimization for the estimation of static shift and interpretation of 1-D magnetotelluric sounding data

open access: yesAnnals of Geophysics, 2011
In the presence of conducting inhomogeneities in near-surface structures, apparent resistivity data in magnetotelluric sounding can be severely distorted. This is due to electric fields generated from boundary charges on surficial inhomogeneities.

Hydroprocessing of synthetic kerosene over a non‐sulphided Ni/Al2O3 catalyst: Impact of alcohols and ketones on alkene conversion

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Synthetic jet fuel containing non‐petroleum‐derived kerosene can be produced from synthetic kerosene obtained through processes that include a hydroprocessing step. The potential use of non‐sulphided (reduced) nickel supported on alumina (Ni/Al2O3) was evaluated as an alternative to sulphided catalysts to saturate alkenes in sulphur‐free ...

Effect The Use of Steel Fibers (Dramix) on Reinforced Concrete Slab

open access: yesCSID Journal of Infrastructure Development, 2019
Currently concrete technology continues to grow and continue to innovate one of them using fibers. Fiber concrete has advantages over non-fiber concrete, among others: strong against the effect of shrinkage, ability to reduce crack, fire resistance, etc.
