Endohedral metallofullerenes have been extensively studied over the past decade because of their unique structural and electronic properties.1 Scandium metallofullerenes are especially interesting because they can contain more than two metal atoms (Sc3@C82) which form metal clusters.2,3 Furthermore, a Sc nitride metallofullerene, Sc3N@C80 has been synthesized recently.4 The structures of these ...

Two types of decisions that directly affect the performance of a distribution system is the vehicle routing and inventory assignment. These problems have been studied separately for many years. The inventory routing problem (IRP) is integration of above mentioned distribution problems. In the other words, IRP assumes each customer maintains a local inventory of a product and consumes a certain ...

Superconducting behavior even under harsh ambient conditions is expected to occur in La@C60 if it could be isolated from the primary metallofullerene soot when functionalized by CF3 radicals. We use ab initio density functional theory calculations to compare the stability and electronic structure of C60 and the La@C60 endohedral metallofullerene to their counterparts functionalized by CF3. We f...

The title compound, C(72)F(36), is one of four isomers of C(60)(CF(3))(12) for which crystal structures have been obtained. The fullerene mol-ecule has an idealized I(h) C(60) core with the 12 CF(3) groups arranged in an asymmetric fashion on two ribbons of edge-sharing C(6)(CF(3))(2) hexa-gons, a para-meta-para-para-para-meta-para ribbon and a para-meta-para ribbon, giving an overall pmp(3)mp,...

In immortalized cells of the erythroid lineage, the iron-regulatory protein (IRP) has been suggested to coregulate biosynthesis of the iron storage protein ferritin and the erythroid delta-aminolevulinate synthase (eALAS), a key enzyme in heme production. Under iron scarcity, IRP binds to an iron-responsive element (IRE) located in ferritin and eALAS mRNA leaders, causing a block of translation...

It is commonly proposed that the number of fibers that do not cross in the optic chiasm (OC) is proportional to the size of the binocular visual field, and that the major advantage of binocular vision is acute depth perception. I present an alternative, an ‘eye-forelimb’ (EF) hypothesis, suggesting that alterations in the OC influence the length of neural pathways that transmit visual informati...

Carbon clusters exhibit a broad diversity of topologies and shapes, encompassing fullerene-like cages, graphene-like flakes, more disordered pretzel-like branched structures. Here, we examine computationally their infrared spectra in relation with these structures from statistical perspective. Individual for samples isomers were determined by means the self-consistent charge density functional-...

AIMS To compare the International Normalised Ratio (INR) obtained directly with the two types of WHO plain International Reference Preparation for thromboplastin in patients treated with coumarin. METHODS Prothrombin times were performed in parallel at four centres using WHO human plain IRP (BCT/253) and rabbit plain IRP (RBT/79). Sixty patients and 20 normal controls were tested at each cent...
