Uncertainties in Galactic Chemical Evolution Models [PDF]
, 2016 We use a simple one-zone galactic chemical evolution model to quantify the uncertainties generated by the input parameters in numerical predictions for a galaxy with properties similar to those of the Milky Way.

Hypernova Nucleosynthesis and Galactic Chemical Evolution [PDF]
, 2001 We study nucleosynthesis in 'hypernovae', i.e., supernovae with very large explosion energies ($ \gsim 10^{52} $ ergs) for both spherical and aspherical explosions.

GRBs as Cosmological Probes - Cosmic Chemical Evolution [PDF]
, 2006 Long-duration gamma-ray bursts (GRBs) are associated with the death of metal-poor massive stars. Even though they are highly transient events very hard to localize, they are so bright that they can be detected in the most difficult environments.

The Chemical Evolution of the Galaxy [PDF]
Symposium - International Astronomical Union, 1985 Over the last few years, our picture of the chemical evolution of the Galaxy has changed substantially. These changes are of interest because chemical evolution provides a common point of contact for most astrophysical processes of importance to galaxy evolution.

Chemical Evolution of a Bacterium’s Genome [PDF]
Angewandte Chemie International Edition, 2011 We set out to develop a generic technology for evolving the chemical constitution of microbial populations by using the simplest possible algorithm. Extant living cells polymerize a restricted set of nucleic acid precursors, namely, four nucleoside triphosphates (UTP, CTP, ATP, GTP) and four deoxynucleoside triphosphates (dTTP, dCTP, dATP, dGTP ...

Chemical Evolution Tomorrow [PDF]
, 2002 The solar system is just one sample, though of course the most thoroughly studied sample, of cosmic chemistry. Some perspective on it can be gained from an overview of the chemical evolution of the Galaxy and Universe, how our knowledge of this evolution has developed, and what problems remain to be solved.

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024
Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...
