Valuation of projects for the preservation of water resources provides important information to policy makers and funding institutions. Standard contingent valuation models rely on distributional assumptions to provide welfare measures. Deviations from assumed and actual distribution of benefits are important when designing policies in developing countries, where inequality is a concern. This article applies semiparametric methods to obtain estimates of the benefit from a project for the preservation of an important Brazilian river basin. These estimates lead to significant differences from those obtained using the standard parametric approach. Copyright 2010 by the American Geophysical Union.

Eight species of Kempnyia Klapálek were collected in the Mantiqueira Mountains at Campos do Jordão, of which six were known: K. colossica (Navás, 1934), K. flava Klapálek, 1916, K. neotropica (Jacobson and Bianchi, 1905), K. obtusa Klapálek, 1916, K. reichardti Froehlich, 1984 and K. tamoya Froehlich, 1984; two are new, K. pirata and K. tupinamba. One new synonymy is proposed. Comments are provided for all species from the area and a key to these species is presented. Copyright © 2011 Magnolia Press.

Gluteal implants are an effective and predictable way to remodel the buttocks. However, depending on the anatomical plane employed and the manner in which the implant pocket is dissected, the results can be frustrating. The only way to prevent palpable or visible implants (the major causes of a poor result) is through the intramuscular plane. The author presents his XYZ technique, which provides anatomical reference points to guide the intramuscular dissection procedure in a feasible and safe way, resulting in a low complication rate. © 2010 The American Society for Aesthetic Plastic Surgery, Inc.

Over the years, several metaheuristics have been developed to solve hard constrained and unconstrained optimization problems. In general, a metaheuristic is proposed and following researches are made to improve the original algorithm. In this paper, we evaluate a not so new metaheuristic called differential evolution (DE) to solve constrained engineering design problems and compare the results with some recent metaheuristics. Results show that the classical DE with a very simple penalty function to handle constraints is still very competitive in the tested problems. © 2012 Elsevier Ltd. All rights reserved.

Background: Circumareolar incisions in breast augmentation surgery can center slightly low areolas on the breast mound and treat moderate ptosis. This maneuver, however, is limited to moderate cases because it does not achieve any lifting of the breast. Objectives: The author describes periareolar augmentation mastopexy (PAM), a new systematic approach of breast augmentation and lifting through a circumareolar incision, by means of a vertical or T-plication on the lower pole of the breast. Methods: Twenty-eight patients underwent PAM. Intraoperatively, the epidermis was stripped on the area between the areola and the circumareolar incisions; after abundant tumescent infiltration, a detachment was performed on the areolar plane at the breast's lower pole. The submuscular plane was reached through a vertical incision on the breast, and a high-profile implant was placed. Over the same incision, a strong plication was performed to tighten the laxity causing the ptosis. The skin was closed with a purse-string suture. Results: The complication rate was low in this patient series: one case of small necrosis of the periareolar skin, one case of areolar asymmetry, three cases in which the areolas were not postoperatively round, and one case of infection in the unilateral purse-string suture. All patients saw great improvement in breast shape and were satisfied with ptosis correction. The technique results in minimal postoperative scarring, since it relies on a single circumareolar incision. Conclusions: In this small series, PAM proved to be an excellent technique with consistent aesthetic results for correction of hypomastia in patients with moderate to minimally severe ptosis. © 2012 The American Society for Aesthetic Plastic Surgery, Inc.
