Arbuscular mycorrhizal (AM) symbiosis is generally considered to be effective in ameliorating the plant tolerance to salt stress. Unfortunately, the comprehension of the mechanisms implicated in salinity stress alleviation by AM symbiosis is far from being complete. Thus, an experiment was performed by growing durum wheat (Triticum durum Desf.) plants under salt-stress conditions to evaluate th...

The title double salt containing two distinct, differently protonated hexa-molybdoplatinate(IV) polyanions, Na6[H5.5 α-PtMo6O24][H4.5 α-PtMo6O24]·29H2O, has been synthesized by a hydro-thermal reaction at ca pH 1.80. The positions of the H atoms in the polyanions were established from difference Fourier maps and confirmed by the inter-polyanion hydrogen bonds, bond-distance elongation, and bond...

Harvester ants (Messor galla Forel) defied various control strategies. Two field experiments were conducted to evaluate the effects of Spent Engine-Oil and other nature-based materials on their emergence in Maiduguri, Borno State of Nigeria. The treatments evaluated are spot application of spent engine-oil and some natural materials in experiment 1 and individual and equal mixture of Pure Neem ...

Hybrid fiber reinforced concrete (HFRC) consisting of two or more different types of fibers has been widely investigated because of its superior mechanical properties. In the present study, the effect of the addition of steel (0.25%, 0.5%, 0.75%, and 1% of concrete volume) and Polypropylene (0.2%, 0.4%, and 0.6% of concrete volume) fibers on the surface scaling resistance of concrete, depth of ...

1. A standard duodenal perfusion technique was used to study the effects of luminally perfused sodium taurocholate on basal and stimulated biliary and pancreatic secretion and gastrointestinal hormone release in man. 2. During duodenal perfusion with sodium taurocholate alone, both basal and caerulein/secretin-stimulated bilirubin secretion were suppressed. A successive perfusion with a mixture...

This is the first report on the measurement of homogeneous nucleation temperature, TH, in the presence of aqueous mixed salt systems of varying compositions and ionic strengths. The TH,m (TH value in aqueous mixed salt system) data for these systems have been analyzed in terms of a simple empirical equation. The TH,m values in simple aqueous mixed salts like NaCl-KCl can be approximated by line...
