Novel poly(vinyl chloride) matrix membrane electrodes for the azide ion are developed, electrochemically evaluated and used for manual and flow injection determinations of soluble and insoluble metal azides. These electrodes ...

The construction of liquid membrane and PVC matrix-type cocainium ion selective electrodes and their use for direct potentiometry and potentiometric titration of cocaine are described. The ion-pair complexes of cocaine ...

Growth and photosynthetic performance were assessed for the Finnish wheat Triticum aestivum L. var. APU under a cool (13/10�C day/night) and a warm (30/25�C day/night) regime. Plants exhibited a certain degree of acclimation ...

Dry and fresh Azolla pinnata were evaluated as feed ingredients for fingerling and adult Nile tilapia, Oreochromis niloticus (L.). Dry Azolla was incorporated into practical diets containing approximately 30% crude protein ...

5,6-Dimethylenebicyclo[2.2.1]hept-2-ene (I) polymerizes in the presence of the two-component ring opening metathesis polymerization (ROMP) initiators WCl6/(CH3)4Sn and MoCl5/(CH3)4Sn. The product polymers were insoluble ...

Redundant robots have many applications and use in path synthesis for crowded workspace and in minimum time control path tracking problems. In selected manufacturing applications - such as spray painting, continuous welding, ...

The dioxouranium(VI)-Schiff base complex (N,N'-p-phenylenebis(salicylideneiminato)UO2); (UO2(sal-p-phdn)) was prepared. Its resonance Raman, infrared and electronic spectra were obtained and assigned on the basis of C2v ...

In this paper, an assessment of the performance of one of the multistage flash (MSF) desalination units operating in conjunction with the gas-turbine cogenera-tion power plant in Qatar is carried out under different operating ...

Chemical study of the lipid fraction resulted in the isolation and identification of a hydrocarbon fraction (n-Czg -0-033); an aliphatic alcohol fraction (C^, Czp, €30) and a sterol fraction (stigmasterol and sitosterol). ...
