The Age and Origin of Block Deposits in the Victorian Alps, Australia

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Large periglacial block deposits are found in the mountains of southeastern Australia. Despite their widespread distribution, their mode of formation and age are poorly understood. These landforms hold considerable potential to shed light on the nature of cooling during glacial periods. In this paper we present a new study of block deposits in

Wheat fertilization affects oviposition preference of wheat midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae)

Pest Management Science, EarlyView.
Wheat fertilization increased plant growth, nitrogen and protein levels, influencing the wheat volatile profile and affecting female wheat midge choice to lay eggs. This could partly result from the observed changes in the VOC profile. Abstract BACKGROUND In Canada, the orange wheat blossom midge (hereafter called wheat midge), Sitodiplosis mosellana ...

Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

Pest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...

Using MALDI‐FTICR Mass Spectrometry to Enhance ZooMS Identifications of Pleistocene Bone Fragments Showing Variable Collagen Preservation

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Recent advances in high‐throughput molecular analyses of collagen peptides, especially ZooMS (Zooarchaeology by Mass Spectrometry), have permitted breakthroughs in the analysis of archaeological material that is highly fragmented, a factor that hinders morphological identification.

Cross‐Linking Mass Spectrometry of the Antimicrobial Peptides Magainin 2 and PGLa Reveals Heterodimerization in Micellar Medium

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale In this study, we applied cross‐linking mass spectrometry (XL‐MS) to characterize the oligomeric states of a PGLa/magainin 2 mixture and gain insight into the heterodimerization previously suggested in the literature. Both peptides have shown a synergistic enhancement of activity when tested in antimicrobial assays; however, the ...

Determination of Copper by Isotopic Dilution

Biological Trace Element Research, 1994
A rapid and selective method was used for the determination of copper by isotopic dilution employing substoichiometric extraction with dithizone in carbon tetrachloride. The appropriate pH range for the substoichiometric extraction was 2-7. In the analysis, even a large excess of elements forming extractable complexes with dithizone does not interfere.

Spiking isotope dilution

Journal of Radioanalytical Chemistry, 1975
The isotope dilution method, which is based on the isolation of a constant substoichiometric amount, can be completed by a group of radiometric techniques in which this amount is a function of the concentration to be determined. It is convenient then to plot the experimental data in such a way that a straight line is obtained.
