Effects of irrigation and cultivation on the chemical indices of saline–sodic soils in a calcareous environment
Studies on saline–sodic soils have a growing concern during time in many arid and semiarid nations due to human population pressures and need to produce more food and fiber. Nevertheless, little data are avail...

Impact of parent rock and topography aspect on the distribution of soil trace metals in natural ecosystems
The concentration and dynamic of soil trace metals in natural ecosystems, in particularly, is dependent on the lithology of parent rock as well as topography and geopedological processes. To ascertain more kno...

The spatial distribution of potassium status and clay mineralogy in relation to different land-use types in a calcareous Mediterranean environment
In order to investigate changes caused in clay mineralogy and potassium (K) status by different land-use types, 42 soils samples (0–30 cm) were monitored and analyzed. Soil samples belonging to Reference Soil ...

Open AccessSome results on fixed points of α-ψ-Ciric generalized multifunctions
In 2012, Samet, Vetro and Vetro introduced α-ψ-contractive map**s and gave some results on a fixed point of the map**s (Samet et al. in Nonlinear Anal. 75:2154-2165, 2012). In fact, their technique generalize...

Open AccessOn fixed points of α-ψ-contractive multifunctions
Recently Samet, Vetro and Vetro introduced the notion of α-ψ-contractive type map**s and established some fixed point theorems in complete metric spaces. In this paper, we introduce the notion of ...

Impact of long-term wastewater irrigation on variability of soil attributes along a landscape in semi-arid region of Iran
Twelve soil profiles and 62 soil cores were described from two neighboring landscapes in the northwest of Iran to understand whether long-term wastewater irrigation has caused variations in morphological, phys...

Best proximity results in regular cone metric spaces
First, we define the notion of distance between two subsets in regular cone metric spaces. Then, we establish some conditions which guarantee the existence of best proximity points for cyclic contraction mappi...

Soil quality response to long-term wastewater irrigation in Inceptisols from a semi-arid environment
Thirty-nine paired soil samples belonging to Inceptisols, irrigated with wastewater and well water, were examined to monitor the combination of clay mineralogy, physicochemical properties, and trace metals (Zn...

Strategic design of competing supply chain networks for inelastic demand
A model for designing the network of a new entrant supply chain under inelastic demand and in the presence of pre-existing competing chains is proposed. These supply chains provide an identical product for a m...
