This study conducted in Aljabal alakhdar (Green Mountain), Derna, Libya. It is the only wet region Like other Mediterranean forests, it exposed to risk of fires. To assist this, two different geographical units from (coastal and mountain), which been burned at times; identify whether these soils are regaining their pre-burn status over time. The studied properties were: soil clay content, organ...

Several methods for determining exchangeable sodium in human subjects by using the gammaray emitter Na22 (half-life 2.6 years) in conjunction with measurements of body radioactivity have previously been described (1-3). With these methods, it is possible to make repeated exchangeable sodium determinations over a period of several weeks or months after giving a single tracer dose of the radioiso...

Let Ω be a Borel subset of SN where S is countable. A measure is called exchangeable on Ω, if it is supported on Ω and is invariant under every Borel automorphism of Ω which permutes at most finitely many coordinates. De-Finetti’s theorem characterizes these measures when Ω = SN. We apply the ergodic theory of equivalence relations to study the case Ω 6= SN, and obtain versions of this theorem ...

Research on the soil structural effects of potassium (K) in irrigation wastewaters has received limited attention due to the typically low abundance of K in most waters. Winery processing wastewater however tends to have elevated concentrations of both K and sodium (Na). This study investigated the contrasting cation dynamics under municipal and winery wastewater following irrigation to a heavy...

A pot experiment was conducted at screen house of Department Soil Science, PAU, Ludhiana during rabi 2017-18 to evaluate the response wheat applied potassium. Twelve soil samples were taken from all over Punjab varying in available K. Potassium @ 0, 15, 20, 25 and 30 kg K/ha soil. The mean grain yield varied 12.39 20.13 g/pot K sufficient soils (>137 K/ha) 8.43 12.09 deficient (<137 K/ ha...

Distributions over matrices with exchangeable rows and infinitely many columns are useful in constructing nonparametric latent variable models. However, the distribution implied by such models over the number of features exhibited by each data point may be poorly-suited for many modeling tasks. In this paper, we propose a class of exchangeable nonparametric priors obtained by restricting the do...

A hypergraph is a generalization of a graph in which an edge may contain more than two vertices. Hereditary hypergraphs are particularly important because they arise in mathematics as the class of monotone subsets, in statistics as the class of factorial models, in topology as simplicial complexes and in algebra as the free distributive lattice. An exchangeable random hypergraph consists of a p...

Little information is available on chemical forms of heavy metals on integrate plant roots. KNO3 (1 M), 0.05M EDTA at pH6 and 0.01 M HCl were used sequentially to extract the exchangeable, complexed and precipitated forms of Cu(II) and Cd(II) from soybean roots and then to investigate chemical form distribution of Cu(II) and Cd(II) on soybean roots. Cu(II) and Cd(II) adsorbed on soybean roots w...
