Port organizations have focused their efforts on physical or tangible assets, generating profitability and value. However, it is recognized that the greatest sustainable competitive advantage is the creation of knowledge using the intangible assets of the organization. The Balanced ScoreCard, as a performance tool, has incorporated intangible assets such as intellectual, structural and social c...

PURPOSE Temporary tissue expanders (TTE) with an internal magnetic metal port (IMP) have been increasingly used for breast reconstruction in post-mastectomy patients who receive radiation therapy (XRT). We evaluated XRT plans of patients with IMP to determine its effect on XRT dose distribution. METHODS AND MATERIALS Original treatment plans with CT simulation scans of 24 consecutive patients...

Introduction Photonic crystal is a periodic structure consisting of high contrast dielectrics, in which the electromagnetic wave cannot transmit in a specific wavelength range. It is therefore known that, if localized defects are introduced in the photonic crystal, the electromagnetic fields are strongly confined around the defects. For example, point defects in the photonic crystal work as res...

External beam radiation therapy (RT) is often offered to breast cancer patients after surgical mastectomy followed by breast reconstruction with silicone implants. In some cases, the RT is administered while the patient is still implanted with a temporary tissue expander including a high-density metallic port, which is expected to affect the planned dose distribution. This work uses Monte Carlo...

Indicators of environmental policies in force Mexico, fossil fuels will continue to be used industrial sectors, especially marine fuels, such as diesel oil, port systems for some time. Considering this, we have evaluated several methods corresponding a top-down system determining fuel consumption and sulfur dioxide atmospheric emissions the Veracruz 2020 by type ship on daily resolution, consid...

A 13-month-old boy underwent placement of a tissue expander in the subgaleal plane in the forehead. The indication for skin expansion was a large congenital melanocytic nevus involving the forehead and glabella. Serial inflations of the expander were performed in the plastic surgery clinic using sterile equipment. Alcohol was used to prepare the skin overlying the injection port. Three months f...

We consider an asymmetric version of a two-dimensional Coulomb gas, made up of two species of pointlike particles with positive +1 and negative −1/Q (Q = 1, 2, . . . ) charges; Q = 1 corresponds to the symmetric two-component plasma and the limiting case Q → ∞ is related to the one-component plasma. The system lives on the surface of a sphere, and it is studied in both canonical and grand-canon...

Acquired port-wine stain is a rare vascular lesion that mimics a congenital port-wine stain clinically and histologically, but is acquired after birth. A survey on more than 60 reported cases in the literature reveals that most of these cases are idiopathic, but some of the cases developed after physical or mechanical trauma, hormonal changes, chronic sun exposure, and medications (OCP, i...
