For linearly elastic heterogeneous solids, averaging theorems are developed by Nemat-Nasser and Hori (S. Nemat-Nasser, M. Hori, Micromechanics: Overall Properties of Heterogeneous Solids, Elsevier, Amsterdam, 1993; and S. Nemat-Nasser, M. Hori, J. Eng. Mater. Technol. 117 (1995) 412), using a multi-inclusion model. This model is based on the observation that the average strain and stress in any...

Hydrocephalus arising from intraventricular septations is known as complex or loculated hydrocephalus. Many synonyms for complex hydrocephalus have been used in the literature such as compartmentalized or loculated hydrocephalus. Complex hydrocephalus remains a challenging neurosurgical problem. Definitive treatment is surgical, yet the approach remains controversial. Traditional treatment cons...

The honorable editor-in-chief of the Journal of ARYA We read with interest the article of Dr. Maleki that has recently been published.1 We conducted a similar study in Birjand Vali-e-Asr Hospital in 20092010. This study was done on 125 patients with STEMI with a mean age of 59.2 ± 11.9 years. In this study, 65.6% of patients underwent thrombolytic therapy. This showed a crucial increase compare...

S could be the procedure of choice for preserving lung function in patients with peripheral stage IA non–small cell lung cancer if indeed it can provide the same rate of disease-free survival as lobectomy. A randomized trial currently underway should help to address some of the surgical community’s concerns about the size and conduct of the previous randomized trial that made lobectomy the surg...

A general method for homogenization of the electromagnetic properties of a heterogeneous periodic medium is developed, based on its microstructure. This method is inspired by micromechanics (Nemat-Nasser and Hori, 1999). Contrary to other conventional techniques, commonly used in electromagnetism to calculate the overall properties of composites, this microstructurally-based method does not req...

In the first few microseconds following the Big Bang, the very hot and dense Universe was thought to be in a state of matter known as the quark gluon plasma (QGP). The QGP is rather different from the normal matter we observe everyday; protons and neutrons are examples of particles in which quarks and gluons are bound. It is said that quarks and gluons are confined in Nature; we do not observe ...
