this study considers the level of increase in customer satisfaction by supplying the variant customer requirements with respect to organizational restrictions. in this regard, anp, qfd and bgp techniques are used in a fuzzy set and a model is proposed in order to help the organization optimize the multi-objective decision-making process. the prioritization of technical attributes is the result ...
Organic soil horizons function as important controls on the thermal state of near-surface soil and permafrost in high-latitude ecosystems. The thermal conductivity of organic horizons is typically lower than mineral soils and is closely linked to moisture content, bulk density, and water phase. In this study, we examined the relationship between thermal conductivity and soil moisture for differ...
in this study argillic horizons in calcareous soils of a semiarid region, with xeric and mesic soil moisture and temperature regimes, in the west of urmia lake were studied. thus, a toposequence in different physiographic positions including piedmont plains, plateau, hills and mountains was investigated. in each land type, three soil profiles were dug and described and their morphological prope...
the investment horizons of institutional investors can affect monitoring incentives which might ultimately make an impact on firm CSR decisions. Hence, this paper investigates the effects of institutional investor’s investment horizons on CSR activities.This research has been carried out using annual data of companies accepted in Tehran Stock Exchange during the period of 2011-2018. By screenin...
development of argillic horizon in loess derived soils under xeric and udic soil moisture regimes was studied in golestan province. soils were classified as hapludalfs and haploxeralfs. high leaching, stability of the surface, forest vegetation,structure and well drainage conditions provide appropriate conditions for clay migration through the profile and formation of argillic horizons. in the ...
Turbic Cryosols (permafrost soils characterized by cryoturbation, i.e., by mixing of soil layers due to freezing and thawing) are widespread across the Arctic, and contain large amounts of poorly decomposed organic material buried in the subsoil. This cryoturbated organic matter exhibits retarded decomposition compared to organic material in the topsoil. Since soil organic matter (SOM) decompos...
Non-Hermitian Hamiltonians H 6= H possess the real (i.e., observable) spectra inside certain specific, “physical” domains of parameters D = D(H). In general, the determination of their “observability-horizon” boundaries ∂D is difficult. We list the pseudo-Hermitian real N by N matrix Hamiltonians for which the “prototype” horizons ∂D are defined by closed analytic formulae.
Surāhī (decanter) can be regarded as one of the most common types of drinking vessels in Persian art as well as one of the containers mentioned most in Persian literature (especially in mystical literature). In this study, in order to complete this information in the Safavid era, in both domains, the method of reconstructing the horizons of Hans Robert Jauss was employed. Explaining the theoret...
Potassium fixation is one of the most important factors influencing the availability of this ion for plants. This research was carried out to evaluate the relationship between potassium (K) fixation with some physical and chemical characteristics of soils and clay minerals and to investigate the effect of the dry and wet cycle on potassium fixation in Kakan Plain, in Kohgilouye & Boyerahmad Pro...
