The purpose of this work was to provide information on heavy metals concentration in soils and in irrigation water in Thessaly, Central Greece, where tobacco (Nicotiana tabacum) is cultivated. Tobacco tends to accumulate high levels of heavy metals, especially Cadmium. During the years 1998, 1999 and 2000, 795 surface soil samples (0-30 cm depth) and 200 water samples were collected from Kardit...
Eg 1: The sodium pyrophosphate (Na-pyro) extractable data (highlighted) in Table 3 are wrong as published. The correct version of the table is given below. The error occurred in the revision phase of the manuscript (the table was correct in the first version) when the acid oxalate data were copied twice. We apologize for the mistake. The description in the manuscript is based on the correct dat...
Extractability is one of the main and central tools for design and analysis of modern cryptographic protocols. We say a function is extractable if any adversary that outputs a point in the range of the function is guaranteed to ”know” a corresponding preimage. This research presents a short report on the existence of extractable one-way functions based on a recent paper by Bitansky et al. [BCPR...
abstract- to evaluate effects of different soil moisture conditions namely, phosphorus (p) and zinc (zn) application, on extractable zn and fe, two experiments were conducted in laboratory conditions based on a completely randomized design with a factorial arrangement of treatments with two replications. the first experiment was performed with the following factors; incubation time at four leve...
Some improvements in ECIS88 like the use of expansion of the potentials in term of Bessel functions lead to ECIS94 and to write the Notes on ECIS94 before I had to retire on the 1/9/1994. However, on the suggestion of Arjan Koning, the code was modi ed to deal with continuum for compound nucleus calculations. This point, existing in ABAREX was not in ANLECIS. Now, ECIS95 should do the same kind...
The acid-extractable proteins of nucleoli of Walker 256 carcinosarcoma, regenerating rat liver, and thioacetamidetreated rat liver were separated into 91, 94, and 92 spots, respectively, by two-dimensional polyacrylamide gel electrophoresis. Although the protein patterns from these different nucleoli have remarkable similarities, some qualitative and quantitative differences were found among th...
Pearl millet was subjected to air plasma bubbling along with soaking enhance HCl extractable iron by reducing phytic acid content. The pearl soaked for 11 h and 10 followed (1 2 h) at input voltage 180 V lph flow rate. A 64.9% 70.93% of reduction in observed treatments. total content reduced while improved 68% 59% 1 exposure time. significant changes (p≤ 0.05) millet’s physical, nutritional, te...
Remnant forests in urban areas provide vital ecosystem services but are susceptible to many human activities including heavy metal emissions. In this study, we collected 192 samples of mineral soils at depths of 0–3, 3–13 and 13–23 cm in 16 remnant forests (eight natural forests and eight plantation forests) in the urbanized Pearl River Delta, China. We assessed the potential risks of soil Cu, ...
Arbuscular mycorrhizal fungi (AMF) are widespread endosymbionts in terrestrial ecosystems and their exudates have important effects on soil properties. A greenhouse experiment was conducted with six AMF treatments including four exotic species inoculums (Funneliformis mosseae ,Claroideoglomus claroideum and Rhizophagus irregularis and a mixed isolate of three species), one mixed native AMF spe...
The sorption behaviour of divalent cations M2+ (Cu, Pb and zn) and trivalent cations M3+ (Fe, Al) with humic acid isolated from oxidized coal (Hazro,se Anatolia,Turkey) was followed in aqueous solution. Coal humic acid and metal ion interaction was investigated with special emphasis on the effects of pH, metal ion concentration and humic acid concentration. it has been found that the interactio...
