The work was carried out at the College of Agricultural and Veterinary Sciences of the State University of São Paulo (UNESP/FCAV), Campus of Jaboticabal, Brazil, aiming to study the tolerance response to water stress and capacity of regeneration after mowing three different ornamental grasses used in Brazilian landscaping: Imperial zoysia grass (Zoysia japonica 'Imperial'), zoysia grass (Zoysia japonica) and St. Augustine grass (Stenotaphrum secundatum). The experimental design was entirely randomized in a factorial scheme 33 (three grass species: Zoysia japonica 'Imperial', Zoysia japonica and Stenotaphrum secundatum; in three water stress conditions: under full sun, with and without irrigation, and under greenhouse conditions without irrigation) with four replications per plot. The irrigation was performed using microsprinklers with a flow of 0.28 L s-1, and the grasses of all plots were mowed monthly. The evaluations were executed monthly, before mowing the grass, in the beginning of each season, that means, in October (for Spring evaluation), January (for Summer), April (for Autumn) and July (for Winter), considering the Brazilian climate conditions. The evaluated parameters were shoot height and total dry mass. The data were submitted to the variance analysis and the means were compared by the Tukey test at 5% confidence level. The grasses grown under greenhouse conditions, without irrigation, showed higher height and lower dry mass weight averages, what possibly indicates that the plants etiolated. The grasses grown under full sun, either with or without irrigation, showed a similar plant development. The S. secundatum species showed greater tolerance to water stress in October, month that followed the longest dry period. The total dry mass was gradually reduced during the experiment for all grasses grown under greenhouse conditions without irrigation; however, a great general tolerance to water stress was observed for all grasses because all of them survived along nine months without irrigation.

Background: Surgical approaches to temporomandibular region have been the subject of numerous controversies in the literature. Pre-auricular approaches have been used with the observance of high success rate, and during surgery history, various modifications of this approach were conducted in order to reduce irreversible sequelae. Thus, given the relevance of the study, this article proposes to alert the professionals that carry out these surgical approaches in relation to the anatomical structures involved and to describe and emphasise the benefits of endaural approach. Case report: A Caucasian male patient, victim of a firearm injury, sustained a wound on the right pre-auricular region, and at the time of assessment, he complained of pain, mouth opening difficulty and dysphagia. On physical examination, there was oedema and ecchymosis in the right periorbital region. In the radiological examination, a foreign body compatible with a firearm projectile was observed in the right pre-auricular region, being in accordance with the information collected. The endaural incision and divulsion by plans was then made until the projectile. Discussion: For proper exposure of the region, several studies were designed to evaluate the patterns of branching and anastomosis of the facial nerve. As for the best cosmetic result with the different pre-auricular approaches, the endaural approach was described as an approach that offers great cosmetic results because the incision design guides the surgeon in the wound closure and causes a decrease in the tension of flap, unlike that observed by some authors. © 2012 Springer-Verlag Berlin Heidelberg.

Access to Latin American and Caribbean Exports in the United States market, 2001-2002 is the seventh annual report released by the ECLAC Washington Office, updating information contained in previous reports. Its aim is to compile and make available information on trade inhibiting measures that Latin American and Caribbean exports encounter in the United States market. This report needs to be placed in the context of a trade relationship between the United States and Latin America and the Caribbean, which has grown strongly over the years to the benefit of both economies. Moreover, it must be viewed against the background of the commitment to achieve the Free Trade Area of the Americas (FTAA), through which barriers to trade and investment will be progressively eliminated. In this regard, it is hoped that this report will further contribute to transparency and the elimination of obstacles to the free flow of trade in the Americas. The classification of trade inhibiting measures follows the definition used in the U.S. Trade Representatives (USTR) yearly publication National Trade Estimate Report on Foreign Trade Barriers. Based on this structure, the report focuses on the three areas of greatest relevance for Latin America and the Caribbean: Imports Policies (e.g., tariffs and other import charges, quantitative restrictions, import licensing, customs barriers). Standards, testing, labeling and certification (e.g., unnecessarily restrictive application of phytosanitary standards). Export subsidies (e.g., export financing on preferential terms and agricultural export subsidies that displace other foreign exports in third country markets).
