One of the main problems of SMEs is how to finance their investments. The role of banks in this regard is crucial, since they can be a type of sources of financing through lending credits directly to SMEs. The key role of the paper thus relies on analyzing the effect of SMEs financing by the Iranian banking system.   The objective of this paper is to determine the influence of loans demanded...

Not only in Iran, but throughout the world, banks and banking industry are considered as very important parts of the economy. This study seeks to investigate the impact of the internal characteristics of banks, the structure of the banking industry and the economic situation of Iran on the profitability of the banking system of Iran by exploring the theory of the Structuralism school concerning...

(2)H quadrupolar line shapes deliver rich information about protein dynamics. A newly designed 3D (2)H-(13)C-(13)C solid-state NMR magic angle spinning (MAS) experiment is presented and demonstrated on the microcrystalline β1 immunoglobulin binding domain of protein G (GB1). The implementation of (2)H-(13)C adiabatic rotor-echo-short-pulse-irradiation cross-polarization (RESPIRATION CP) ensures...

BACKGROUND Involvement of nitric oxide (NO) in the pathophysiology of human African trypanosomiasis (HAT) was analyzed in a HAT animal model (rat infected with Trypanosoma brucei brucei). With this model, it was previously reported that trypanosomes were capable of limiting trypanocidal properties carried by NO by decreasing its blood concentration. It was also observed that brain NO concentrat...

Consider a fixed effects ANOVi\ model. We propose to estimate cell means /lij by MLE's ~ij instead of cell averages ~j, and we propose to estimate error variance by a MLEQ2 rather than the usual mean square for error. Even so, much of the usual ANOVi\ methodology carries over when applied to the ~ij 's, and the efficiency is often increased. When this is generalized to common random effects and...

We run a novel field experiment to link managers of African manufacturing firms. The experiment resembles the many forms of interaction that business and community organizations offer to their members. The design features exogenous link formation, exogenous seeding of information, and exogenous assignment to treatment and placebo. We study the impact of the experiment on firm business practices...

The hyperpolarization (HP) method signal amplification by reversible exchange (SABRE) uses para-hydrogen to sensitize substrate detection by NMR. The catalyst systems [Ir(H)2(IMes)(MeCN)2(R)]BF4 and [Ir(H)2(IMes)(py)2(R)]BF4 [py = pyridine; R = PCy3 or PPh3; IMes = 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene], which contain both an electron-donating N-heterocyclic carbene and a phosphine, ...

In this report we review the literature on the relationship between ICT and productivity. In Sect. 1 we discuss in broad terms thetheoretical relationship between ICT and productivity, while in Sect. 2 we present the growth accounting methodology, whichtries to measure the contributions to growth from difference sources (ICT and non ICT capital, human capital, total factorproduc...
