RESPONSE OF MAIZE GENOTYPES TO FERTILIZATION ON HYDROMORPHIC SOIL OF SAVA VALLEY [PDF]
Poljoprivreda, 2003 Growing seed-maize is more profitable than mercantile maize, but also riskier, especially under less favourable soil conditions because parents of maize hybrids are less tolerant than their progeny to environmental stress, including plant nutrition ...

Absence of photoemission from the Fermi level in potassium intercalated picene and coronene films: structure, polaron or correlation physics? [PDF]
J. Chem. Phys. 136, 134503 (2012), 2012 The electronic structure of potassium intercalated picene and coronene films has been studied using photoemission spectroscopy. Picene has additionally been intercalated using sodium. Upon alkali metal addition core level as well as valence band photoemission data signal a filling of previously unoccupied states of the two molecular materials due to ...

A molecular target for viral killer toxin: TOK1 potassium channels. [PDF]
, 1999 Killer strains of S. cerevisiae harbor double-stranded RNA viruses and secrete protein toxins that kill virus-free cells. The K1 killer toxin acts on sensitive yeast cells to perturb potassium homeostasis and cause cell death. Here, the toxin is shown to

Evaluation of synaptotagmin‐1 action models by all‐atom molecular dynamics simulations
FEBS Open Bio, EarlyView.We used molecular dynamics simulations to test models proposing that synaptotagmin‐1 facilitates membrane fusion by perturbing lipid bilayers, inducing membrane curvature and/or bridging membranes. The simulations show that synaptotagmin‐1 C2‐domains placed near the site of fusion hinder the ability of SNARE complexes to bring the membranes together ...

Modulation Transfer Spectroscopy of the D1 Transition of Potassium: Theory and Experiment [PDF]
arXiv, 2023 We report on a study of modulation transfer spectroscopy of the $4\textrm{S}_{1/2}\rightarrow 4\textrm{P}_{1/2}$ ($D_{1}$) transition of naturally abundant potassium in a room-temperature vapour cell. This transition is critical for laser cooling and optical pumping of potassium and our study is therefore motivated by the need for robust laser ...

Proton block and voltage gating are potassium-dependent in the cardiac leak channel Kcnk3. [PDF]
, 2000 Potassium leak conductances were recently revealed to exist as independent molecular entities. Here, the genomic structure, cardiac localization, and biophysical properties of a murine example are considered.

FEBS Open Bio, EarlyView.Cerebral organoids were employed as a novel model to explore the neurotoxicity of soman. Soman inhibited acetylcholinesterase activity, increased cell apoptosis and upregulated endoplasmic reticulum (ER) stress markers glucose‐regulated protein 78 (GRP78), activating transcription factor 6 (ATF6) and C/EBP homologous protein (CHOP).

Structural and electronic changes of pentacene induced by potassium doping [PDF]
Phys. Rev. B 95, 134112 (2017), 2017 Potassium is introduced into the crystalline herringbone structure of pentacene searching for a compound showing metallic electronic transport properties and, hopefully, superconductivity at small enough temperatures. Several possible structures for stoichiometric KPentacene (1:1), K2Pentacene (2:1) and K3Pentacene (3:1) compounds are theoretically ...
