Effects of hybrid metal oxide nanoparticles on the tribological and emission attributes of algae‐derived biofuel in compression ignition engines

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The growing demand for sustainable fuels has accelerated the development of algae‐derived biodiesel for compression‐ignition engines. In this study, Chlorella vulgaris methyl ester (AME) exhibited physicochemical properties comparable to diesel and satisfied ASTM D6751 fuel quality requirements, making it suitable for blending.

Circadian rhythms of locomotor activity in captive Emin's mole-rats, Heliophobius emini (Rodentia : Bathyergidae) [PDF]

, 2017
Many African mole-rats (Bathyergidae) exhibit distinct circadian rhythms, despite the fact that they are strictly subterranean and are very infrequently exposed to light.

SPE–HPLC–UV determination of NSAIDs in freshwater: Analytical optimization and environmental risk assessment in northwestern Tunisia

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Non‐steroidal anti‐inflammatory drugs (NSAIDs) are among the most frequently detected emerging contaminants in aquatic environments. Their occurrence and environmental fate are governed by complex interactions involving physicochemical and environmental factors. This study aimed to develop, validate, and apply a reliable HPLC–UV method for the

Multi‐Objective RSM Optimization of Emission and Performance Characteristics in a Diesel Engine Fueled With BaTiO3 Nano‐Enhanced Jojoba Biodiesel

Energy Science &Engineering, EarlyView.
This study uses response surface methodology to optimize Jojoba biodiesel blended with BaTiO3 nanoparticles in a single‐cylinder diesel engine. Results show that ~48.95–51.31 ppm of BaTiO3 achieves balanced performance and emission, decreasing CO and NOx while increasing torque and brake thermal efficiency.

Trading new neurons for status: Adult hippocampal neurogenesis in eusocial Damaraland mole-rats [PDF]

, 2016
Diversity in social structures, from solitary to eusocial, is a prominent feature of subterranean African mole-rat species. Damaraland mole-rats are eusocial, they live in colonies that are characterized by a reproductive division of labor and a ...

Coupled Assessment of Injection Pressure–Driven Risk, Trapping Evolution, and Cost Uncertainty in Geological CO2 Storage

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Scaling geological CO2 storage requires simultaneously controlling plume migration, pressure buildup, geomechanical integrity, and monitoring cost under deep subsurface uncertainty. Yet early‐stage assessments often treat these elements in isolation, obscuring the decision‐critical couplings between pressure‐defined regulatory exposure and ...

Naked mole-rat transcriptome signatures of socially suppressed sexual maturation and links of reproduction to aging

BMC Biology, 2018
Background Naked mole-rats (NMRs) are eusocially organized in colonies. Although breeders carry the additional metabolic load of reproduction, they are extremely long-lived and remain fertile throughout their lifespan.

Decoding the Tunnel Behavior of Damaraland Mole-rats (Fukomys damarensis) [PDF]

, 2021
Damaraland mole-rats, Fukomys damarensis, are an African rodent species that is one of two mammalian species considered eusocial. Damaraland mole-rats (DMR) live in large colonies comprised of a breeding pair and their non-reproductive offspring in ...

Tectono‐Sedimentary Evolution of the Neogene İnegöl Basin (NW Anatolia): Constraints on Transtensional Basin Development at the Junction of the Western Anatolian Extensional Province and the North Anatolian Fault Zone

Geological Journal, EarlyView.
The study outlines the tectono‐sedimentary evolution of the İnegöl Basin in north‐western Anatolia. Basin formation was controlled by interacting extensional and strike‐slip fault systems linked to uplift of the Uludağ Massif. Terrestrial sedimentation from the Miocene to Pleistocene is reconstructed using abundant fossil mammal assemblages that ...

Life in groups: the roles of oxytocin in mammalian sociality

Frontiers in Behavioral Neuroscience, 2013
In recent decades, scientific understanding of the many roles of oxytocin in social behavior has advanced tremendously. The focus of this research has been on maternal attachments and reproductive pair-bonds, and much less is known about the substrates ...
