Mass Measurements of Proton-rich Nuclei with JYFLTRAP
(Jagiellonian University, 2011)
The Penning trap setup JYFLTRAP, connected to the IGISOL facility, has been extensively used for atomic mass measurements of exotic nuclei. On the proton rich side of the chart of nuclei mass measurements have mostly ...
Can number and size of offspring increase simultaneously? – A central life-history trade-off reconsidered
(BioMed Central (BMC), 2012)
Background: To maximize their fitness, parents are assumed to allocate their resources optimally between number and size of offspring. Although this fundamental life-history trade-off has been subject to long standing ...
Control of matrix interferences by multiple linear regression models in the determination of arsenic and lead concentrations in fly ashes by inductively coupled plasma optical emission spectrometry
(RSC - Royal Society of Chemistry, 2010)
A multiple linear regression technique was used to evaluate and correct the matrix interferences in the determination of As and Pb concentrations in fly ashes by inductively coupled plasma optical emission spectrometry. ...
The determination of antimony and arsenic concentrations in fly ash by hydride generation inductively coupled plasma optical emission spectrometry (HG-ICP-OES)
(Elsevier, 2011)
Hydride generation inductively coupled plasma optical emission spectrometry (HG-ICP-OES) was used in the determination of As and Sb concentrations in fly ash samples. The effect of sample pre-treatment reagents and measurement ...
Loss of density-dependence and incomplete control by dominant breeders in a territorial species with density outbreaks
(BioMed Central (BMC), 2011)
Background:
A territory as a prerequisite for breeding limits the maximum number of breeders in a given area, and thus lowers the proportion of breeders if population size increases. However, some territorially breeding ...
Kestrel hunting behaviour towards solitary and grouped Microtus agrestis and M. epiroticus — a laboratory experiment
(1992)
Extensive field data show that avian and mammalian predators take more Microtus epiroticus than coexisting Microtus agrestis voles. The different vulnerability of these vole species may arise from prey selection or ...
The subtle balance of weak supramolecular interactions: The hierarchy of halogen and hydrogen bonds in haloanilinium and halopyridinium salts
(Beilstein-Institut, 2010)
The series of haloanilinium and halopyridinium salts:
4-IPhNH₃Cl (1), 4-IPhNH₃Br (5), 4-IPhNH₃H₂PO₄ (6), 4-ClPhNH₃H₂PO₄ (8), 3-IPyBnCl (9), 3-IPyHCl (10) and 3-IPyH-5NIPA (3-iodopyridinium 5-nitroisophthalate, 13), where ...
Sexual conflict over the duration of copulation in Drosophila montana: why is longer better?
(BioMed Central (BMC), 2009)
Background.
Conflicts of interest between the sexes are increasingly recognized as an engine driving the (co-)evolution of reproductive traits. The reproductive behaviour of Drosophila ...
Computational Exploration of Subnano Zn and Cu Species on Cu/ZrO2 : Implications for Methanol Synthesis
(American Chemical Society (ACS), 2024)
Ternary Cu/Zn/ZrO2 catalysts prepared recently using atomic layer deposition (ALD) have shown increased performance toward methanol synthesis. In the present computational study, we have investigated the structure, ...
Growth and longevity of the endangered freshwater pearl mussel (Margaritifera margaritifera) : Implications for conservation and management
(Wiley, 2024)
Key life-history data, such as growth and age, are necessary to effectively manage and conserve threatened freshwater mussel species. Traditionally growth and age studies require large yet destructive sample sizes covering ...
