The complex chemistry of uranyl nitrate with mono and bi-functional neutral extractants shows, that it forms 1:2 and 1:1 complexes respectively. The structures of the isolated complexes show, that the water molecules from the primary coordination sphere of [UO2(NO3)2.2H2O] are replaced by the extractants completely and adopt a hexagonal bi-pyramidal geometry. However, the structural chemistry o...

Paradigmatic Influences on Metadiscourse Features in Medical Research Articles

For the recent decades, scholars have examined the use of metadiscourse markers (MDMs) paradigmatically through several comparative studies across varying languages and cultures. No study to date, however, has investigated a comprehensive, full-fledged comparison of the possible disparities among the native English writers (NEW), Iranian English writers (IEW), and Iranian Persian writers (IPW) ...

On Clarification to the Previously Published Research Articles

In the recent literature, attempts have been made to propose new statistical distributions for modeling real phenomena of nature by adding one or more additional shape parameter (s) to the distribution of baseline random variable. The major contribution of these distributions are to obtain monotonic and non-monotonic shaped failure rates. This short article, offers a clarification to the resear...

Foreword. Bioceramic research on intelligent implants and drug delivery system.

Hydroxyapatite (HAp, Ca10(PO4)6(OH)2) has a hexagonal crystalline system and is a mineral component of vertebrate hard tissues, an important raw biomaterials and an element of drug delivery systems. It is commonly used as a filler to replace amputated bone or as a coating to promote bone ingrowth into prosthetic implants. There are, therefore, two historical research approaches to develop bioco...
