این مطالعه به بررسی و مقایسه همگرایی بازار محصولات کشاورزی در D8 و G7 طی دوره زمانی 1995-2012 با استفاده از مدل جاذبه پرداخته است. براساس نتایج برآورد، مدل جاذبه به ترتیب حدود 79 و 96 درصد از ترتیبات تجاری بخش کشاورزی بین کشورهای D8 و کشورهایG7 را توضیح میدهد. همچنین، نتایج مطالعه نشان دادند که ضریب برآوردی متغیر ارزش افزوده بخش کشاورزی کشورهای i و j برای گروه D8 و G7 مثبت است. ضریب برآور...
The immobilized, low-spinal turtle produces 3 forms of the fictive scratch reflex in response to tactile stimulation of specific sites on its body surface (Robertson et al., 1985). We used complete transections of the spinal cord at different rostrocaudal levels to reveal the minimum length of spinal cord sufficient to produce each scratch form. Additional transections revealed the progressive ...
Epoxy ternary systems were prepared from the diglycidylether of bisphenol-A (DGEBA), epoxidized castor oil (ECO), and nano-CaCO3 using a thermally latent initiator. The effects of ECO and the nano-CaCO3 contents on the thermal stability and mechanical interfacial properties of the prepared DGEBA/ECO/nano-CaCO3 ternary systems were examined by thermogravimetric analysis (TGA), Izod impact tests,...
Eco-labeling signals that a product has been eco-certified. While there is increasing use of eco-labeling practices, there is still little understanding of the conditions under which eco-labels can command price premiums. In this paper, we argue that the certification of environmental practices by a third party should be analyzed as a strategy distinct from although related to the advertisement...
We consider a D4 − D8 − D8 brane construction which gives rise to a large N QCD at sufficiently small energies. Using the gravity dual of this system, we study chiral phase transition at finite chemical potential and temperature and find a line of first order phase transitions in the phase plane. We compute the spectral function and the photon emission rate. The trace of the spectral function i...
Eco-cover is ecological mulch and its application is an eco-friendly and low-cost method to improve soil environment and prevention of unwanted plants. The aim of this study was to investigate the effects of eco-cover on unwanted plants, Vetiver grass (Chrysopogon zizanioides) growth and soil Properties. For this purpose, two series of rectangular plot (with and without eco-cover), in three rep...
Figure 2. H NMR spectra of (a) [R4N ]2[IrX6 2−] in toluene-d8 obtained after mixing the organic (toluene-d8) layer of TOAB (2.0 mmol) and the aqueous (D2O) layer of K2IrCl6 (0.4 mmol), (b) 1-dodecanthiol (0.8 mmol) added to a, (c) 1-dodecanthiol (1.6 mmol) added to a, (d) NaBH4 (4.0 mmol) added to c, (e) S-dodecylthiosulfate (0.8 mmol) added to a, and (f) Ir nanoparticle in CDCl3 after purifica...
Pattern-avoiding involutions, which have received much enumerative attention, are patternavoiding permutations which are invariant under the natural action of a certain subgroup of D8, the symmetry group of a square. Three other nontrivial subgroups of D8 also have invariant permutations under this action. For each of these subgroups, we enumerate the set of permutations which are invariant und...
Acknowledging and understanding the role that information may play in affecting consumer assessment of eco-marketed products is a key step in improving the effectiveness of eco-labeling initiatives. Consumers who hold preferences for environmentally preferred products may be unable to express their preferences for such goods under current eco-information campaigns. The emerging use of eco-label...
