Three-dimensional Aromaticity of Ferrocene

Biicosahedral metallaboranes: aromaticity in metal derivatives of three-dimensional analogues of naphthalene.

Consideration of the well-known very stable icosahedral B12H12(2-) as a three-dimensional analogue of benzene was extended by the recent synthesis of the biicosahedral B21H18(-) as a three-dimensional analogue of naphthalene. The preferred structures of metallaboranes derived from B21H18(-) have now been examined by density functional theory. The isoelectronic species CpNiB20H17 and CpCoCB19H17...

Three-Dimensional Image of A Communicating Uterus

Recent advances in reproductive medicine have created a demand for more accurate and safe imaging modalities before assisted reproductive treatment(ART) (1). Gradually, the important role of three-dimensional (3D) ultrasonography in the diagnosis of uterine congenital anomalies has been proved (2-4).

Three-Dimensional Simulation of Qeshm Channel Currents

Qeshm Channel is a shallow and narrow waterway located between Qeshm Island and the mainland in the vicinity of Hormuzgan Province, Islamic Republic of Iran. This channel is important because of its economic, industrial, fisheries and navigation role it plays as well as environmental issues it presents in the region. A prognostic study was performed to simulate currents in this channel, using C...

Outsourcing through Three-dimensional Competition

In this paper, we study an outsourced supply chain consisting of one buyer and two suppliers in which the buyer outsources manufacturing of a physical product to two competing suppliers. The suppliers compete for the buyers' demands share, and the buyer allocates the demands to the competing suppliers based on three-dimensional allocation functions. We consider two certain types of allocation f...
