Based on the collective forest with common use rights, social-ecological system analysis framework and autonomous governance theory proposed by Elinor Ostrom are introduced in eco-economic to analyze interaction logic among first-level subsystems secondary variables of related explore synergistic mechanisms affecting system. The results show that: case information asymmetry, actions governmenta...
Four lipophilic 1,10-phenanthroline di(thio)amide, diester or diketone derivatives were studied as ligands for Am(III)/Eu(III) separation from acidic media. The synthesis of these compounds is reported together with the extraction tests in different solvents (kerosene, octanol and o-nitrophenyl hexyl ether), HNO3 concentrations and ratios between the ligand and the synergistic agent (Br-Cosan)....
To understand how information is coded in the primary somatosensory cortex (S1) we need to decipher the relationship between neural activity and tactile stimuli. Such a relationship can be formally measured by mutual information. The present study was designed to determine how S1 neuronal populations code for the multidimensional kinetic features (i.e. random, time-varying patterns of force) of...
The potential of the ERS-1/2 scatterometer global soil moisture product has been shown in several studies. The ASCAT sensor on-board the METOP satellite is extending the 16 year time series of the ERS-1/2 scatterometer as a source for extracting information for ocean and land applications. Calibrated ASCAT data will continue the scatterometer global soil moisture archive while improving both th...
A review of the existing leadership literature in organizations shows that there is no comprehensive theoretical framework for synergistic leadership that is generally agreed upon. Therefore, this study seeks to identify and explain the dimensions of synergistic leadership in the form of a systematic model for Iranian universities using the grounded theory. Semi-structured interviews were used ...
A Box-Behnken design (BBD) was applied to optimize the ultrasound-assisted extraction of polysaccharides from mulberry leaves. Under the optimum conditions of an extraction temperature of 57 °C, an extraction time of 80 min and a liquid/solid ratio of 53 mL/g, the mulberry leaf polysaccharide (MLP) yield was 6.92 ± 0.29%. Then, three fractions of MLPs were obtained by deproteinization, dialysis...
Extraction of microamounts of europium and americium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H+B-) in the presence of dodecaethylene glycol (DDEG, L) has been investigated. The equilibrium data have been explained assuming that the species HL+, H2L2+, ML3+ and MH-1L2+ (M3+ = Eu3+, Am3+; L = DDEG) are extracted into the organic phase. The values of extraction and stability c...
با استفاده از روشهای پلاریزاسیون تافل و طیف بینی امپدانس الکتروشیمیایی، اثر بازدارندگی دو ماده شیمیایی آلی به نام های اسیدتانیک و اسیدگالیک که جزء گروه تانن ها می باشد، با و بدون اضافه کردن تعدادی ممانعت کننده معدنی نظیر نیتریت ، مولیبدات و پلی فسفات برخوردگی فولاد نرم (mild steel) در محیط آب برج خنک کننده با ph قلیایی (حدود 8 ) بررسی شده است . اضافه کردن اسید گالیک به محلول حاوی یون نیتریت و م...
