در این تحقیق تاثیر متغیرهایی از قبیل مصرف انرژی٬ تولیدات کارخانه ای٬ درجه باز بودن اقتصاد٬ سرمایه‌گذاری مستقیم خارجی و رشد اقتصادی بر انتشار گاز دی اکسید کربن برای سال‌های (2010-1990) در کشورهای گروه D8 در قالب یک الگوی اقتصادسنجی با استفاده از داده‌های تلفیقی (پانل دیتا) و روش گشتاورهای تعمیم یافته برآورد شده است. نتایج نشان می‌دهد که در روش اثرات ثابت تمام متغیرهای مورد بررسی به جز سرما...
In this paper we present the aggregational motifs of the widely used alkali-metal cyclopentadienides (CpLi, CpNa, CpK, CpRb, CpCs) in THF-d8 solution estimated by ECC-DOSY NMR spectroscopy. They form monomeric contact ion pairs (CIPs) in THF-d8 solution, whereas in NH3 solvent-separated ion pairs (SSIPs) are observed. The applicability of ECC-DOSY is further advanced by introducing ECC-MW estim...
As a top-down holographic approach, the D4/D8 model is expected to be version of QCD, since it almost includes all elementary features QCD based on string theory. In this manuscript, we review fundamental properties with respect D4-brane background and embedding flavor branes, quark, gluon, meson, baryon glueball various symmetries; then, take look at some interesting applications developments ...
BACKGROUND A dinoflagellate genus Ostreopsis is known as a potential producer of Palytoxin derivatives. Palytoxin is the most potent non-proteinaceous compound reported so far. There has been a growing number of reports on palytoxin-like poisonings in southern areas of Japan; however, the distribution of Ostreopsis has not been investigated so far. Morphological plasticity of Ostreopsis makes r...
Using the boundary state formalism, we perform a microscopic string analysis of the interaction between two D-branes and provide a local interpretation for the R-R force in the D0-D8 brane system. To do so, we construct BRST invariant vertex operators for the massless R-R states in the asymmetric picture that are proportional to potentials rather than field strengths. The Hilbert space of such ...
This paper presents a study in an efficient methodology for analysis and characterization of digital images psoriasis lesions using Daubechies D8 wavelet technique. The methodology is based on the transformation of 2D Discrete Wavelet Transform (DWT) algorithm for Daubechies D8 at first level to obtain the coefficients of the approximations and details sub-images. For classification method, sta...
