Comparative Analysis of Alternative Fuels Used in Road Transport

open access: yes, 2017
In recent years, especially alternative fuels have been undergoing significant and rapid development, since the society is aware of the negative impacts of a long term and excessive use of fossil fuels on the environment as well as of the fact that the ...

Operationalizing BioSSbD: A safe‐and‐sustainable‐by‐design framework for biorefineries

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biorefineries are central to the transition toward a circular bioeconomy; however, their increasing scale and technological heterogeneity, and the integration of biological, chemical, and thermochemical processes introduce complex challenges related to safety, sustainability, and operational reliability. Existing Safe‐and‐Sustainable‐by‐Design

Utilization of alternative marine fuels for gas turbine power plant onboard ships

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2013
Marine transportation industry is undergoing a number of problems. Some of these problems are associated with conventional marine fuel-oils. Many researchers have showed that fuel-oil is considered as the main component that causes both environmental and

Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

open access: yesBiological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Assessing the On-Board Storage and Use of Ammonia as a Fuel Applying the House of Quality

open access: yesJournal of Marine Science and Engineering
Ammonia as a fuel has been known for several years, but only relatively recently has it attracted interest for study and use as a marine fuel. A forthcoming generation of sustainable, economically viable, and safe technologies for the large-scale onboard

The influence of circadian variables on ecotoxicology metabolomics

open access: yesBiological Reviews, EarlyView.
ABSTRACT Ecotoxicologists are using metabolomics increasingly to gain insight into toxicological mechanisms and sublethal effects of chemical exposures. Metabolomics offers a sensitive multi‐parameter approach that can detect biochemical responses not obvious using apical and behavioural endpoints.
