Heavy weight vehicle traffic and its relationship with antimony content in human blood

Quiroz W.; De Gregori I.; Basilio P.; Bravo M.; Pinto M.; Lobos M.G. (2014-04-04)

Brake pads systems are nowadays considered as one of the most important sources of antimony in airborne particulate matter. One way that antimony can enter the body is through the lungs and specially by the interaction of ...

Helium core white dwarfs missing in cataclysmic variables?

Zorotovic M.; Schreiber M.R. (2014-04-04)

Binary population synthesis predict a population of helium-core white dwarfs (He WDs) in cataclysmic variables (CVs) that is not observed in the available sample of CVs. An independent test on the fraction of He WDs in ...

The Helmholtz equation in a locally perturbed half-plane with passive boundary

Duran M.; Muga I.; Nedelec J.-C. (2014-04-04)

In this article, we study the existence and uniqueness of outgoing solutions for the Helmholtz equation in locally perturbed half-planes with passive boundary. We establish an explicit outgoing radiation condition which ...

The Helmholtz equation in a locally perturbed half-space with non-absorbing boundary

Duran M.; Muga I.; Nedelec J.-C. (2014-04-04)

We obtain uniqueness and existence results of an outgoing solution for the Helmholtz equation in a half-space, or in a compact local perturbation of it, with an impedance boundary condition. It is worth noting that these ...

The Helmholtz equation with impedance in a half-space

Duran M.; Muga I.; Nedelec J.-C. (2014-04-04)

In this Note we obtain existence and uniqueness results for the Helmholtz equation in the half-space ℝ+3 with an impedance or Robin boundary condition. Basically, we follow the procedure we have already used in the ...

Hemichannels in the neurovascular unit and white matter under normal and inflamed conditions

Orellana J.A.; Figueroa X.F.; Sanchez H.A.; Contreras-Duarte S.; Velarde V.; Saez J.C. (2014-04-04)

In the normal brain, cellular types that compose the neurovascular unit, including neurons, astrocytes and endothelial cells express pannexins and connexins, which are protein subunits of two families that form plasma ...

Heterobimetallic Re-Pd, Re-Au and Re-Cu complexes derived from diphenylphosphino cyrhetrene: Synthesis and X-ray structure

Sierra D.; Munoz A.; Godoy F.; Hugo Klahn A.; Ibanez A.; Teresa Garland M.; Fuentealba M. (2014-04-04)

Diphenylphosphinecyrhetrene ligand (η5-C5H4PPh2)Re(CO)3 (1) reacts with 1 equiv. of PdCl2(NCPh)2 to form, after workup, the square-planar trans-[(η5-C5H4PPh2)Re(CO)3]PdCl2(NCMe) (2). Similarly, reaction of 1 with ...

Heterobimetallic RePd complexes bridged by η1: η5-Ph2PC5H4 ligand. Synthesis, electronic and crystal structure of (CO)2(PR3) (η5-C5H4PPh2)Re-PdCl 2, R = Me and OMe

Sierra D.; Klahn A.H.; Ramirez-Tagle R.; Arratia-Perez R.; Godoy F.; Teresa Garland M.; Fuentealba M. (2014-04-04)

The new rhenium complexes (η5-C5H 4PPh2)Re(CO)2(PR3) (R = Me (1) and OMe (2)) were prepared photochemically from (η5-C 5H4PPh2)Re(CO)3 in the presence of PMe3 or P(OMe)3. Further reaction of these ligands with PdCl2(NCPh)2 ...

Heterogeneous enzyme kinetics

Because of their excellent functional properties (activity, selectivity, specificity), enzymes have a great potential as industrial catalysts in a number of areas of chemical industry: fine chemistry, food chemistry, ...

A heuristic approach for a logistics districting problem

Gonzalez-Ramirez R.G.; Smith N.R.; Askin R.G.; Kalashinkov V. (2014-04-04)

This article addresses a logistics districting problem for a company whose operations consist of the pickup and delivery of packages within a region. The service region is to be divided into districts, each served by a ...

A heuristic approach for a multi-product capacitated lot-sizing problem with pricing

Gonzalez-Ramirez R.G.; Smith N.R.; Askin R.G. (2014-04-04)

We address a multi-product capacitated lot-sizing problem with pricing. The objective is to maximise profit. The problem extends the multi-product capacitated lot-sizing problem (CLSP) found in the literature to include ...
