In Early Modern Persian prose and verse, verbs with a present stem accompanied by grapheme "-y" have been used to express modal concepts of imperative and command or invocation and request. Researchers, regardless of the historical changes of Early Modern Persian, believe that this structure of  subjunctive 2nd person singular has been used to express imperative mood, and that &q...

The historical development of a scientific knowledge on calcium orthophosphates from the 1770s until 1940 is described. Many forgotten and poorly known historical facts and approaches have been extracted from old publications and then they have been analyzed, systematized and reconsidered from the modern point of view. The chosen time scale starts with the earliest available studies of 1770s (t...

Titanium and its alloy are known as important load-bearing biomaterials. The major drawbacks of these metals are fibrous formation and low corrosion rate after implantation. The surface modification of biomedical implants through various methods such as plasma spray improves their osseointegration and clinical lifetime. Different materials have been already used as coatings on biomedical implan...

The history of seismology has been traced since man first reacted literarily to the phenomena of earthquakes and volcanoes, some 4000 yr ago. Twentysix centuries ago man began the quest for natural causes of earthquakes. The dawn of modern seismology broke immediately after the Lisbon earthquake of 1755 with the pioneering studies of John Bevis (1757) and John Miehell (1761). It reached its pin...

Improving return forecasting is very important for both investors and researchers in financial markets. In this study we try to aim this object by two new methods. First, instead of using traditional variable, gold prices have been used as predictor and compare the results with Goyal's variables. Second, unlike previous researches new machine learning algorithm called Deep learning (DP) has bee...

The Field Experiences for Science Teachers (FEST) Program, based in the Department of Geology and Geophysics at Yale University, provides field seismology experiences to secondary school science teachers in Connecticut. Research experiences for K-12 science teachers have been shown in the past to improve students’ test scores and encourage inquiry-based teaching in the science classroom. FEST p...
