Con el objeto de evaluar el efecto de dos horas de corte (7 AM y 5 PM) y seis frecuencia de corte (25, 30, 35, 40, 45,50 días) sobre la composición química de planta entera y fracciones (hojas ramas y tallos) de Moringa oleifera Lam. Se realizó en la finca “El último bosque” propiedad del Sr. Nikolaus Foidl, localizada geográficamente entre la coordenadas 11º50 ́23 ̈ Latitud Norte y 86º 17 ́01 ̈ Longitud Oeste, en San Antonio de arriba, ciudad de Diriamba departamento de Carazo, de Abril a Noviembre del 2003. Las variables en estudio fueron: porcentaje de materia seca (%MS), porcentaje de proteína bruta (%PB), porcentaje de fibra bruta (%FB), porcentaje de lípidos totales (%LT). Además del rendimiento de biomasa fresca materia seca, proteína bruta, fibra bruta y lípidos totales. Se realizó análisis de varianza y comparaciones de media con la Prueba de rangos múl tiples (Tukey 5%) utilizando el programa SAS (v. 8.0), aplicando un diseño de parcelas divididas. Se encontró diferencia significativa (P>0.05) para el factor edad de corte en todos los tratamientos, a excepción de la variable lípidos totales en la que no ejerció ningún efecto significativo (P<0.05). El factor hora de corte solo ejerció efecto significativo sobre la variable porcentual materia seca, siendo la mejor hora de corte a las 5:00 PM. La interacción hora de corte – edad de corte no presento efecto significativo para ninguno de los tratamientos. Según la Prueba de rangos múltiples (Tukey 5%), se encontró que en las variables materia seca y fibra bruta los mejores resultados se logran a la edad de 50 días con 14.525 y 18.2125% respectivamente; para pr oteína bruta a la edad de 40 días con 22.678% y para lípidos totales a la edad de 45 días con 5.3725%. A 50 días se obtuvieron los más altos rendimientos de biomasa fresca, materia seca, proteína bruta, y fibra bruta con 209.05, 30.808, 5.5052 y 6.7430 (to n/ha/año) respectivamente; en lípidos totales a la edad de 45 días con 1.3641 (ton/ha/año). En la fracción hojas los mayores porcentajes de proteína se obtuvieron en la frecuencia de corte de 40 días con 33.54%, lípidos totales a los 45 días con 8.75% y ma teria seca a los 30 días con 19.30%. En la fracción ramas los mas altos porcentajes se logran al ser cosechadas a la edad de 30 días, obteniéndose un 12.03% de proteína, a los 45 días 3.21% de lípidos totales y a los 50 días 14.1% de materia seca. Mientras que en la fracción tallos los mejores valores de proteína y lípidos totales se logran a los 40 días, 12.06% y 2.56% respectivamente, en materia seca los mayores rendimientos porcentuales se logran a la edad de 40 y 50 días (11.7%)

This document presents the results of baseline monitoring of a repaired coral reef injured by the M/V Wave Walker vessel grounding incident of January 19, 2001. This grounding occurred in Florida state waters within the boundaries of the Florida Keys National Marine Sanctuary (FKNMS). The National Oceanic and Atmospheric Administration (NOAA) and the Board of Trustees of the Internal Improvement Trust Fund of the State of Florida, (“State of Florida” or “state”) are the co-trustees for the natural resources within the FKNMS. This report documents the efficacy of the restoration effort, the condition of the restored reef area two year and four months post-effort, and provides a picture of surrounding reference areas, so as to provide a basis for future comparisons by which to evaluate the long-term success of the restoration.

In October 2000 the government of Cambodia announced a major change in fisheries management policy. The core elements of the new policy are the reduction of fishing lot concession areas by 56%, the broader participation of fishing communities in the management of fisheries and a focus on the efficient, sustainable and equitable use of the living aquatic resources. To facilitate the establishment and development of the Community Fisheries, support and monitor their activities, the Department of Fisheries was authorized1 to establish a Community Fisheries Development Office (CFDO).

Na campanha do desarmamento organizada pela Organização Não Governamental Viva Rio - e realizada entre meados de 2004 e outubro de 2005, com o Referendo Sobre a Proibição do Comércio de Armas de Fogo no Brasil , os atores, discursos e práticas envolvidos na causa do desarmamento se voltavam, majoritariamente, a uma estratégia de apelo aos corações aos cidadãos de bem como forma de persuasão, atrelavam, de modo amplo, a defesa ao desarmamento à defesa à paz e ao combate à violência, e se concentravam, principalmente, na divulgação e promoção da campanha de entrega das armas. Para o debate em torno do Estatuto do Desarmamento e do Referendo, entretanto, novos atores entraram na disputa e começaram a ganhar visibilidade na esfera pública. Os atores engajados pelo "não" no Referendo acionaram aliados e seus discursos em prol de sua causa, recorrendo a elementos da moral e da religião na defesa da posse de armas como um direito inalienável dos cidadãos.Este trabalho reflete sobre as ações engendradas pelo Viva Rio em torno da questão do desarmamento desde sua fundação - com destaque para a Campanha do Desarmamento de 2004 -, discutindo a presença da religiosidade em suas iniciativas e a contribuição desta na constituição de noções de paz, violência e cidadania no espaço público brasileiro. Examina, ainda, de que modo estas noções fundamentaram a atuação pública do Viva Rio na construção de uma cultura da paz e ajudaram a compor um campo de parcerias e disputas no cenário nacional.

Fishery observers collected data from 307 tows during 96 trips aboard skimmer trawl vessels in Louisiana’s coastal waters from September 2004 through June 2005 to estimate catch rates of target and nontarget species, including sea turtles (Cheloniidae and Dermochelyidae), by area and season during commercial shrimping operations. About 16,965.7 kg of total catch were recorded during 517.0 hours of fishing operations. Based on weight extrapolations from species composition samples, penaeid shrimp (Penaeidae) dominated the catch at 66%, followed by finfish at 19%, nonpenaeid shrimp crustaceans at 7%, discarded penaeid shrimp at 6%, and debris at 3%. Noncrustacean invertebrates comprised less than 1%. Catch rates in kilograms per hour by category was 21.6 for penaeid shrimp, 6.2 for finfish, 2.2 for nonpenaeid crustaceans, 1.8 for discarded penaeid shrimp, and 0.9 for debris. White shrimp, Litopenaeus setiferus, other penaeid shrimp, and Gulf menhaden, Brevoortia patronus, were the top three dominant species by weight. Seasonally, a higher catch rate was observed from May through August 2005 for penaeid shrimp as compared with the September through December 2004 period. Conversely, the September through December 2004 period experienced a higher catch rate for finfish than during May through August 2005. No sea turtle interactions were documented.

The National Oceanic and Atmospheric Administration (NOAA), in cooperation with the New Jersey Marine Sciences Consortium (NJMSC), hosted a workshop at Rutgers University on 19-21 September 2005 to explore ways to link the U.S. Integrated Ocean Observing System (IOOS) to the emerging infrastructure of the National Water Quality Monitoring Network (NWQMN). Participating partners included the Mid-Atlantic Coastal Ocean Observing Regional Association, U.S. Geological Survey, Rutgers University Coastal Ocean Observing Laboratory, and the New Jersey Sea Grant College. The workshop was designed to highlight the importance of ecological and human health linkages in the movement of materials, nutrients, organisms and contaminants along the Delaware Bay watershed-estuary-coastal waters gradient (hereinafter, the “Delaware Bay Ecosystem [DBE]”), and to address specific water quality issues in the mid-Atlantic region, especially the area comprising the Delaware River drainage and near-shore waters. Attendees included federal, state and municipal officials, coastal managers, members of academic and research institutions, and industry representatives. The primary goal of the effort was to identify key management issues and related scientific questions that could be addressed by a comprehensive IOOS-NWQMN infrastructure (US Commission on Ocean Policy 2004; U.S. Ocean Action Plan 2004). At a minimum, cooperative efforts among the three federal agencies (NOAA, USGS and EPA) involved in water quality monitoring were required. Further and recommended by the U.S. Commission on Ocean Policy, outreach to states, regional organizations, and tribes was necessary to develop an efficient system of data gathering, quality assurance and quality control protocols, product development, and information dissemination.

Data collected from 12 marine monitoring stations in Daya Bay from 1982 to 2004 reveal a substantial change in the ecological environment of this region. The average N/P ratio increased from 1.377 in 1985 to 49.09 in 2004. Algal species changed from 159 species of 46 genera in 1982 to 126 species of 44 genera in 2004. Major zooplankton species went from 46 species in 1983 to 36 species in 2004. The annual mean biomass of benthic animals was recorded at 123.10 gm(2) in 1982 and 126.68 g m(2) in 2004. Mean biomass and species of benthic animals near nuclear power plants ranged froth 317.9 g m(2) in 1991 to 45.24 g m(2) in 2004 and from 250 species in 1991 to 177 species in 2004. A total of 12-19 species of hermatypic corals and 13 species of mangrove plants were observed in Daya Bay from 1984 to 2002. 2008 Elsevier Ltd. All rights reserved.

A retrospective study of patients hospitalized with influenza and/or pneumonia in a Niagara area community hospital for the influenza season 2003-04 was designed with the main goal of enhancing pneumonia surveillance in acute care facilities and the following specific objectives: 1) identify etiologies, factors, and clinical presentation associated with pneumonia; 2) assess the ODIN score on ICU patients to predict outcomes of severe pneumonia; 3) identify the frequency of pneumonia and influenza in a hospital setting; and 4) develop a hospital pneumonia electronic surveillance tool. A total of 172 patients' charts (50% females) were reviewed and classified into two groups: those with diagnosis of pneumonia (n=132) and those without pneumonia (n=40). The latter group consisted mainly of patients with influenza (85%). Most patients were young (<10yrs) or elderly (>71yrs). Presenting body temperature <38°C, cough symptoms, respiratory and cardiac precomorbidities were common in both groups. Pneumonia was more frequent in males (p= .032) and more likely community-acquired (98%) than nosocomial (2%). No evidence of ventilator-associated pneumonia was found. Microbiology testing in 72% of cases detected 19 different pathogens. In pneumonia patients the most common organisms were Streptococcus pneumoniae (3%), Respiratory syncytial virus (4%), and Influenza A virus (2%). Conversely, Influenza A virus was identified in 73% of non-pneumonia patients. Community-acquired influenza was more common (80%) than nosocomial influenza (20%). The ODIN score was a good predictor of mortality and the new electronic surveillance tool was an effective prototype to monitor patients in acute care, especially during influenza season. The results of this study provided baseline data on respiratory illness surveillance and demonstrated that future research, including prospective studies, is warranted in acute care facilities.
