Fluctuations of the intergalactic UV background towards two lines of sight [PDF]

open access: yes, 2006
We present a reanalysis of the HeII Lyman alpha absorption towards the quasars HS1700+6416 and HE2347-4342 using new high S/N, optical observations. An alternative analysis method is applied, which fits the high quality, optical HI data directly to the ...

Are Large Particles of Iron Detrimental to Properties of Powder Metallurgy Steels?

open access: yesMetals, 2020
It is experimentally shown that a removal of particles exceeding 100 microns in size from iron powders typically used in the fabrication of medium density powder metallurgy steels has a weak effect on apparent density, flowability and compressibility of

Cumulative gravitational lensing in Newtonian perturbations of Friedman-Robertson-Walker cosmologies [PDF]

open access: yes, 2000
It is a common assumption amongst astronomers that, in the determination of the distances of remote sources from their apparent brightness, the cumulative gravitational lensing due to the matter in all the galaxies is the same, on average, as if the ...

Changes in the physical properties and specific mechanical energy of corn-mango peel extrudates

open access: yesCyTA - Journal of Food, 2020
A corn-mango peel blend was processed using a laboratory-scale single-screw extruder, which led to the determination of the apparent density, yellowness, and specific mechanical energy of the extrudate.

Comment on Breakup Densities of Hot Nuclei [PDF]

open access: yes, 2006
In [1,2]the observed decrease in spectral peak energies of IMFs emitted from hot nuclei was interpreted in terms of a breakup density that decreased with increasing energy. Subsequently, Raduta et al.

The intermediate line region in active galactic nuclei [PDF]

open access: yes, 2016
We show that the recently observed suppression of the gap between the broad line region (BLR) and the narrow line region (NLR) in some AGN can be fully explained by an increase of the gas density in the emitting region.
