Trace Element Content in Soils with Nitrogen Fertilisation and Humic Acids Addition [PDF]
Application of mineral fertilisers can entail an increase in trace element content in the soil. In consequence, their elevated uptake by plants and transfer to further trophic chain links may occur.

Improved Strength-Ductility of Ti-6Al-4V Casting Alloys with Trace Addition of TiC-TiB2 Nanoparticles [PDF]
In this work, a high strength–ductility Ti64 cast alloy, containing trace TiC-TiB2 nanoparticles, was fabricated by adding dual-phased nano-TiC-TiB2/Al master alloys to the molten Ti64 alloys.

Effects of Trace Erbium Addition on Microstructure and Mechanical Properties of Ti6Al4V-xEr Alloys [PDF]
In order to discern the effect of rare earth element Er addition on grain refinement of the most widely used titanium alloy Ti6Al4V, new erbium modified Ti6Al4V alloys with compositions of Ti6Al4V-xEr (x = 0, 0.2, 0.4, 0.6 wt %) were developed and ...

High temperature strengthening mechanism of pure Zn with trace Mn addition
This work reveals how trace Mn significantly improves high temperature strength of pure Zn. The peak stress of pure Zn increases from 46 MPa to 84 MPa at 300 °C/0.1 s−1 after 0.8 wt.% Mn addition.

Impact behaviour and fractography of 6061 alloy with trace addition of Sn
The impact behaviour of 6061 alloy with trace amount of 0, 0.04, and 0.08 wt.% Sn was studied in the as-cast (AC), as-roll (AR) and peak-age roll (PAR) processing state. Additionally, the fracture mechanism was also studied in the AC and PAR state.

Künneth formulas for motives and additivity of traces [PDF]
We prove several K nneth formulas in motivic homotopy categories and deduce a Verdier pairing in these categories following SGA5, which leads to the characteristic class of a constructible motive, an invariant closely related to the Euler-Poincar characteristic. We prove an additivity property of the Verdier pairing using the language of derivators,

Contribution to a study of organic solvent addition on trace determination by FAAS [PDF]
The influence of the presence of an organic solvent on the determination of trace elements by flame atomic absorption spectrophotometry (FAAS) was investigated under different experimental conditions. The obtained results show that the effect of
