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

The 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 ...

Actin Isovariant ACT2‐Mediated Cellular Auxin Homeostasis Regulates Lateral Root Organogenesis in Arabidopsis thaliana

Cytoskeleton, EarlyView.
ABSTRACT Lateral root (LR) organogenesis is regulated by cellular flux of auxin within pericycle cells, which depends on the membrane distribution and polar localization of auxin carrier proteins. The correct distribution of auxin carrier proteins relies on the intracellular trafficking of these proteins aided by filamentous actin as a track.

Orbital and eustatic control of basin hydrology during the first stage of the Messinian Salinity Crisis

The Depositional Record, EarlyView.
The paleo‐hydrology of the Sorbas Basin (SE Spain) and the wider Mediterranean region during the deposition of the Primary Lower Gypsum (PLG) stage of the Messinian Salinity Crisis, from ~5.97 to ~5.60 Ma, was affected by tectonics, precession‐forced climate oscillations, and eustatic sea‐level change.

Reviewing and benchmarking ecological modelling practices in the context of land use

Ecography, EarlyView.
Despite habitat loss and degradation are the primary drivers of biodiversity loss, different conclusions have been drawn about the importance of land‐use or land‐cover (LULC) change for biodiversity. Differences may be due to the difficulty of framing a coherent model design to assess LULC effects.

Freshwater fish functional diversity shows diverse responses to human activities, but consistently declines in the tropics

Ecography, EarlyView.
Freshwater environments are intertwined with human activities and the consequence has been environmental degradation and biodiversity loss. Fish provide key ecological and economic benefits, and fish abundance and diversity can be affected by human activities resulting in functional diversity (FD) changes that might scale up to ecosystem impacts ...

Which global circulation model works best for my region? Concordance with genetic data for a Neotropical shrew

Ecography, EarlyView.
Copious questions in global change biology require estimates of climatic suitability for species in the past or future, often via transfers of ecological niche models (ENMs) using outputs from global circulation models (GCMs). However, available GCMs differ markedly, affecting hindcasts and forecasts of species potential distributions. We propose using

Conceptual Model for Communication [PDF]

, 2009
A variety of idealized models of communication systems exist, and all may have something in common. Starting with Shannons communication model and ending with the OSI model, this paper presents progressively more advanced forms of modeling of ...

A Matrix Usage for Load Balancing in Shortest Path Routing [PDF]

, 2009
The Open Shortest Path First (OSPF) protocol is a hierarchical interior gateway protocol (IGP) for routing in Internet Protocol. Traffic flows routed along shortest path and splits the load equally at nodes where a number of outgoing links on the ...
