A total of 108 specimens were prepared to examine the hydraulic performance and strength nine different cement-stabilized soils under unexposed freeze–thaw exposed conditions. Specimens from each mix design evaluated two levels curing conditions (i.e., immature versus mature). Hydraulic conductivity unconfined compressive (UCS) measurements performed assess changes in after 12 cycles freezing at −10 ± 1 °C thawing 22 °C. Measured mass losses a standard brushing test also monitored cycles,...
Abstract Forest soils are sensitive to compaction by forest machinery. operations such as harvesting and skidding have a high potential for soil compaction. This study was carried out in the Hyrcanian hardwood forests of Iran measure changes bulk density (ρb) top 10 cm following machine animal skidding. The change or induced (i) rubber-tired skidder three skid trails: flat trail (STF), with transversal slope (STTS), longitudinal gradient (STLG) (ii) mule two (ATF) (ATTS). Soil cores were...
In this paper, the performance and structural changes in cement-treated soils under influence of freeze/thaw (f/t) exposure are investigated. Specimens from plastic compacted soil-cement mix designs were exposed to different f/t scenarios study dimensionality (i.e., one-dimensional versus three-dimensional exposure) specimens' age at time on their performance. Changes hydraulic conductivity, unconfined compressive strength, longitudinal resonant frequency specimens studied each scenario. An...
1. Increased metabolic rates, pulmonary hypertension and cardiac dysfunction are the most important features of ascites syndrome in broiler chickens. However, mechanism cell injury causing pathogenesis is not clearly understood. Our study aimed to examine generation hydroxyl radicals (OH•) chickens experiencing ascites.2. Three hundred fifty 1-d-old were purchased from a local hatchery reared an open poultry house for 46 d. They divided at random into three groups was induced two by exposing...
Cement-based solidification/stabilization (s/s) is a remediation technology that has been widely used for treatment of range contaminants. Currently, there limited published data on changes in hydraulic performance cement-treated materials subjected to cycles freezing/thawing (f/t). Fourteen sets tests were performed examine the influence factors such as number f/t cycles, freezing temperature, curing time, and mix design conductivity unconfined compressive strength (UCS) silty sand. Results...
Abstract The intensity of soil loss and sediment delivery, representing hydrologic geomorphic processes within a catchment, accelerates with rapid changes in land cover rainfall events. An underlying component sustainable management water resources is an understanding spatial temporal variability the adverse influences regional parameters involved generating following widespread cover. A calibrated algorithm coupled delivery ratio (SDR) was applied raster data layers to improve capability...
The applicability of the dithionite/persulfate (DTN/PS) process for degradation pentachlorophenol (PCP) as an organic contaminant from aqueous solutions was investigated. Effective operational parameters, including initial PCP concentration (25, 50, 100, and 150 mg/L), PS (5, 10, 15, 20 DTN (2.5, 5, 7, 10 solution pH 9, 11), reaction time (3, min) were To identify influences experimental factors involved in degradation, design based on orthogonal array proposed using Taguchi method. Based...
Wastewaters discharged from different industries and hospitals may contain pharmaceuticals, especially dexamethasone (DEX). Thus, we applied the UV/H2O2 photocatalytic method in presence of MgO nanoparticles to remove synthetic wastewater. Moreover, effects parameters such as pH (3-11), hydrogen peroxide concentration (1-8 mM), initial DEX (5-30 mg/L), catalyst dosage (0.01-0.2 g/L) during reaction times (0-30 min) were investigated. Furthermore, efficiency absence catalysts was The...
The present study employed an NH2-MIL-68 (Al) composite for investigating the efficiency of catalytic ozonation process degradation acid blue 113 dye (AB113) from aqueous media. A facile one-step solvothermal method was used to synthesise (Al). effect varied operational parameters such as pH (3–11), initial concentration (20–100 mg/L), catalyst dosage (0.4–2 g/L), and contact time (12–36 min) optimised via use a central design (CCD) through response surface methodology (RSM). results...
In this paper the impact resonance (IR) test method is used as a nondestructive tool to examine curing progression, freeze/thaw (f/t) resistance, and healing potential of cement-stabilized soils. Resonant frequency (RF) measurements on specimens moist cured for up 241 days indicate that main portion hydration process completed after about 60 days. Results RF immature (i.e., 16 days) mature over 110 exposed 12 cycles f/t initial exposure had significant effect degradation structure. After...
