Alternative fuels and ecological aspects of motor vehicle engines
Vojnotehnički Glasnik, 1997 In the last two decades the world has faced two serious problems: the sources of liquid fuels are limited and the number of their users has intensified the problem of their toxicity. The researchers in this field face on extremely complex task: to find a

Integrated Onboard Carbon Dioxide Capture and Liquefaction System for Dual-Fuel Marine Engines
Journal of Marine Science and EngineeringOnboard carbon capture and storage (OCCS) is promising, but downstream CO2 conditioning and liquefaction dominate energy and operability constraints. An integrated OCCS onboard for CO2 conditioning, deep cooling, phase separation and liquid CO2 (LCO2 ...

Impact of Alternative Paraffinic Fuels on the Durability of a Modern Common Rail Injection System
Energies, 2020 Common rail (CR) diesel fuel injection systems are very sensitive to variations in fuel properties, thus the impact of alternative fuels on the durability of the injection system should be investigated when considering the use of alternative fuels.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Epigenetic reprogramming of lineage switching in cancer
FEBS Letters, EarlyView.Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
