Individual aerosol particles from biomass burning in southern Africa: 2. Compositions and aging of inorganic particles

open access: yes, 2003
Individual aerosol particles collected over southern Africa during the SAFARI 2000 field study were studied using transmission electron microscopy and field- emission scanning electron microscopy.

Study of 14N(γ,np)3α Reaction for Eγ up to 150 MeV

open access: yesEast European Journal of Physics, 2022
The reaction 14N(g,np)3a induced by bremsstrahlung photons of endpoint energy Egmax = 150 MeV has been investigated using diffusion chamber, which is placed into the magnetic field.

Focus, Q-Particles and prosodic inversion

open access: yesProceedings of the Linguistic Society of America
This paper examines a second-position focus clitic in Kalaallisut (Inuit, Greenland) and argues that it provides support for Cable’s (2010) theory of Q-particles. Moreover, we demonstrate that anti-pied-piping, in the sense of Branan and Erlewine (2023), extends to possessive structures, a configuration not discussed in their work.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Particles, Objects, and Physics [PDF]

open access: yes, 2005
This thesis analyses the ontological nature of quantum particles. In it I argue that quantum particles, despite their indistinguishability, are objects in much the same way as classical particles. This similarity provides an important point of continuity

Atmospheric tar balls: Particles from biomass and biofuel burning

open access: yes, 2004
"Tar balls'' are amorphous, carbonaceous spherules that occur in the tropospheric aerosol as a result of biomass and biofuel burning. They form a distinct group of particles with diameters typically between 30 and 500 nm and readily identifiable with ...

Relationships between Near-Surface Horizontal Dust Fluxes and Dust Depositions at the Centre and Edge of the Taklamakan Desert

open access: yesLand, 2022
The emission, transport, and deposition of dust are frequently the focus of dust aerosol studies. However, owing to limited observation data, few studies have examined the relationships between the key parameters of dust transport, especially in typical ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Airborne observations of newly formed boundary layer aerosol particles under cloudy conditions [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
This study describes the appearance of ultrafine boundary layer aerosol particles under classical non-favourable conditions at the research site of TROPOS (Leibniz Institute for Tropospheric Research).

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics
