In functional programming it is common to write programs as composition of other simpler functions. This makes it possible to take advantage of the well-known benefits of modular programming. However, in many cases, the resulting programs have efficiency problems caused by the generation of data structures that are solely used for communication between the intervening functions in the compositi...

The hadronic particle production data from relativistic nuclear Pb–Pb 158 A GeV collisions are successfully described within the chemical non-equilibrium model, provided that the analysis does not include Ω and Ω abundances. We show that there is a subtle influence of the Coulomb potential on strange quarks in quark matter which is also seen in our data analysis, and this Coulomb effect confirm...

Soil is a vital parameter for planting design in urban green spaces especially in adverse climate conditions. In this study, the utilization of analytic hierarchy process (AHP) in surveying land suitability for urban green space from measured criteria like suitability indices, including physical (i.e. clay, silt, sand, bulk density, penetration resistance), chemical (i.e. electrical conductivit...

Background: Heavy metals (HMs) are one of the most important polluting substances emitted to the environment during cement production. Tehran Cement Factory located in the southeastern of Tehran, Iran, closer to agricultural lands cultivates alfalfa, barley, and maize as feed. The objective of the study was to determine the concentration of HMs in agricultural soils. Methods: Thirty six soil...

Heavy metal pollution is one of the essential pollutions, and phytoremediation preferred methods to eliminate this pollution. The use degradable chelating agent for efficiency a promising low-cost method removing soil contaminated with heavy metals. In study, it was investigated whether phenanthroline humic acid increase activities Brassica napus L. Chenopodium quinoa Wild. species their applic...

Human activities have led to a considerable increase in trace metal cycling recent times. The mobilized elements get subjected variety of processes leading eventually their re-concentration. polluted sites, transformed by Earth's surface processes, become similar accumulations known from geological records. This study examines authigenic sulfide mineralization two peatlands atmospheric depositi...

micromorphology is the branch of soil science that is concerned with the description, interpretation and, to an increasing extent, the measurement of components, features and fabrics in soils at microscopic level. the advantage of micromorphology is that, in micromorphological studies the soils are studied in their natural and undisturbed form and so, one can follow the processes that take plac...
