In this study we evaluated forest fire risk in the west of Iran using Apriori algorithm and fuzzy c-means (FCM) clustering. We used twelve different input parameters to model Ilam Province. Our results with minimum support confidence show strong relationships between wildfire occurrence eight variables (distance from settlement, population density, distance road, slope, standing dead oak trees, temperature, land cover farm land). study, defined three clusters for each variable: low, middle...

This study examined the effect of zinc supplementation on sleep quality (SQ) intensive care unit (ICU) nurses. In a double-blind, randomized controlled trial, 54 ICU nurses were randomly assigned to intervention group ( n = 27) that received 220 mg sulfate capsules every 72 hours for 1 month and control 26) placebo. Sleep was measured by calculating total score using Pittsburgh Quality Index (PSQI). The serum level secondary outcome. All measurements calculated at both baseline after...

Because the groundwater is considered as major source of 99% all retrievable fresh water, optimization its usage would be very crucial. Groundwater artificial recharge (GAR) using surface water recommended solution because that increases aquifer storage. Detection storage site first step in designing GAR projects. The main objective this research identification suitable sites scattered Shahrekord plain, Chaharmahal-va-Bakhtiari province Iran, Boolean and Fuzzy logic. Data affecting including...

The study focused on the effect of different intensities fire physical and chemical properties soil in Zagros forests western Iran. dominant tree species these is oak (Quercus persica). Three sites were selected; high severity burned site (HS), low (LS) control (not burned) (C). Soil such as: organic matter (OM), total nitrogen (N), NO 3 -N, soluble potassium (K), phosphorus (P), pH, electrical conductivity (EC), cation exchangeable capacity (CEC), base cations (Ca, Mg, Na), CO 2 as...

In forest harvesting operations usually after using skidding machinery (skidders), traces of soil damage in the form compaction and wheel logs ruts can be seen soil. Soil bulk density, which represents compaction, decreases porosity, infiltration rate aeration these turn increase runoff water erosion harvested area. On other hand, a decrease prevents root growth vegetative cover. this study changes density relative due to different number wheeled skidder passes from stump landing for two...

To assess the potential of Pb+2 accumulation in different parts Acacia victoria, one year old A. victoria seedlings were exposed to Pb2+(NO3)2 5 concentrations: 0, 50, 250, 500 and 1000 (mg Pb2+ L(-1)) for 45 days. Subsequently, uptake was quantified roots, shoots leaves by Atomic Absorption Spectroscopy (AAS). In addition, some physiological parameters such as biomass production, roots length, plant appearance, tissue concentrations chlorophyll content examined. Tissue increased...

One of the most economically important non-wood forest products (NWFPs) Zagros forests in west Iran is an oleo-gum resin called 'Saqez', extracted from wild pistachio trees (Pistacia atlantica Desf.). Cooperatives were created about 20 years ago to organize Saqez exploitation by local communities and decrease related ecological threats on forests. The aim this research was evaluate economic, social, impacts extraction cooperatives Ilam province. Thirteen active county Malekshahi selected for...

To be successful in tree establishment, an assessment of land suitability would necessary. The aim this study was determining the potential habitats three native species (Quercus persica, Pistacia atlantica, Amygdalous scoparia) Siahkoh region Ilam County, using Boolean method and Geographic Information Systems (GIS). For regard, slope, aspect hypsometric maps area were produced topographic maps. provide soil properties maps, 40 samples depth 30 cm randomly taken from defined (about 954 ha)....

In a forest-scarce country like Iran, the open semi-arid Zagros forests are single-most important forest region, yet their contribution to rural livelihoods remains inadequately understood. Here our primary focus is on analyzing quantitative contributions of these oak-pistachio tree savannas household incomes in Malekshahi County, Ilam Province, considering both cash and subsistence sources, direct as well indirect incomes. Direct forest-extractive prove be comparatively small (6% incomes),...
