Natural abundance of 15N of a spruce forest ecosystem under acid rain and manipulated clean rain field conditions

Journal of Forest Science, 2008
We analysed stable isotopes of N in a spruce forest under ambient rainfall (no further manipulation of the atmospheric input) and clean rain application (10 years of reduced inorganic N- and acid-constituent input).

Quantum critical Eliashberg theory, the Sachdev-Ye-Kitaev superconductor and their holographic duals

npj Quantum Materials, 2022
Superconductivity is abundant near quantum critical points, where fluctuations suppress the formation of Fermi liquid quasiparticles and the BCS theory no longer applies.

Sum connectedness in proximity spaces

Applied General Topology, 2021
The notion of sum δ-connected proximity spaces which contain the category of δ-connected and locally δ-connected spaces is defined. Several characterizations of it are substantiated. Weaker forms of sum δ-connectedness are also studied.

Methylglyoxal with glycine or succinate enhances differentiation and shoot morphogenesis in Nicotiana tabacum callus

Biologia Plantarum, 2013
The aim of this study was to evaluate the influence of methylglyoxal (MG) on organogenesis and regeneration of tobacco (Nicotiana tabacum L.) plants from callus in media containing glycine or succinate.

Preparation of optically pure δ-lactones using diastereomeric resolution with amino acid as resolving agent [PDF]

, 2015
Synthesis of optically pure δ-lactones by diastereomeric resolution was investigated. Amino acid derivatives, which can be obtained at a relatively low cost, were used as resolving agents.

Differential proline metabolism in vegetative and reproductive tissues determine drought tolerance in chickpea

Biologia Plantarum, 2017
Proline is emerging as a critical component of drought tolerance and fine tuning of its metabolism under stress affects the plants sensitivity and response to stress.
