Water injection for gasoline engines: Potentials, challenges, and solutions
Vaporization of the components of nickel alloys in a vacuum induction furnace
Published in Steel in Translation
When nickel alloys are smelted in a vacuum induction furnace, the challenge is to refine the metal and retain the alloying elements and the nickel. In the present work, a model is developed for the behavior of all the components of complex alloys during refining in a vacuum induction furnace. The limiting stage is assumed to be the transfer of the ...

Cavity-Assisted Generation of Sustainable Macroscopic Entanglement of Ultracold Gases
Prospects for reaching persistent entanglement between two spatially-separated atomic Bose–Einstein condensates are outlined. The system setup comprises two condensates loaded in an optical lattice, which, in return, is confined within a high-Q optical resonator. The system is driven by an external laser that illuminates the atoms, such that photon...
Thermodynamics of the Ranque-Hilsch effect in the three-flow vortex tubes
Published in Theoretical Foundations of Chemical Engineering
In the paper, the apparent violation of the first law of thermodynamics in operating three-flow vortex tubes (3VTs) with mixed stratified flows is discussed when the refrigerating capacity of the 3VTs is higher than with throttling. The authors explain this phenomenon by the dissipation of the kinetic energy of the gas into the ambient medium due t...
Source of the condensates from the Hetianhe Field and the genetic relationship between the condensates and their associa...
Published in Science China Earth Sciences
A detailed correlation of Hetianhe condensates versus typical source rocks from the Tarim Basin was established. Moreover, the genetic relationship between the condensates and their associated gases was also studied based on their geochemical compositions and fluid inclusion data. Hetianhe condensates are characterized by high pristine/phytane (Pr/...
Weak lasing in one-dimensional polariton superlattices.
...Published in Proceedings of the National Academy of Sciences of the United States of America
Bosons with finite lifetime exhibit condensation and lasing when their influx exceeds the lasing threshold determined by the dissipative losses. In general, different one-particle states decay differently, and the bosons are usually assumed to condense in the state with the longest lifetime. Interaction between the bosons partially neglected by suc...
Comparative in vitro toxicity profile of electronic and tobacco cigarettes, smokeless tobacco and nicotine replacement t...
Published in International journal of environmental research and public health
The use of electronic cigarettes (e-cigs) continues to increase worldwide in parallel with accumulating information on their potential toxicity and safety. In this study, an in vitro battery of established assays was used to examine the cytotoxicity, mutagenicity, genotoxicity and inflammatory responses of certain commercial e-cigs and compared to ...
Molecular fossils in Cretaceous condensate from western India
Published in Journal of Earth System Science
The present study reports the biomarker distribution of condensate belonging to the early Cretaceous time frame using gas chromatography–mass spectrometry (GC–MS). The early Cretaceous palaeoenvironment was inscribed into these molecular fossils which reflected the source and conditions of deposition of the condensate. The saturate fraction of the ...
The possible values of critical points between strongly congruence-proper varieties of algebras
Published in Advances in Mathematics
We denote by ConcA the (∨,0)-semilattice of all finitely generated congruences of an (universal) algebra A, and we define ConcV as the class of all isomorphic copies of all ConcA, for A∈V, for any variety V of algebras.Let V and W be locally finite varieties of algebras such that for each finite algebra A∈V there are, up to isomorphism, only finite...
