1-MCP efficiency in quality of ornamental peppers Horticultura Brasileira
Ribeiro,Wellington S; Carneiro,Clebson dos S; França,Christiane de Fátima M; Pinto,Cleide Maria F; Lima,Paula Cristina C; Finger,Fernando L.
ABSTRACT 1-MCP has been effectively used as an antagonist of ethylene deleterious actions in flowers and ornamental plants. The objective was to evaluate the efficiency of 1-MCP (0.0, 0.5, 1.0 and 1.5 g m-3) in maintaining post-production quality of exogenous ethylene sensitive ornamental pepper. Two commercial varieties were evaluated: Pimenta Colorida and Pimentão Ornamental, both Capsicum annuum. The pre-treatment with 1-MCP, regardless of the applied concentration, was effective in blocking the ethylene action reducing the leaves abscission, flowers and fruits of both genotypes by 100%. Plants pretreated with 1-MCP had postproduction life increased by eight and nine days for Pimenta Colorida and Pimentão Ornamental, respectively. The 1-MCP application...

A COMBINATION OF DISCRETE EVENT SIMULATION AND MULTI-CRITERIA ANALYSIS TO CONFIGURE SUGARCANE DROP AND HOOK DELIVERY SYSTEMS REA
Faria,Danilo A. F. de; Frazão,Márcia L. da S.; Vieira,José G. V.; Silva,João E. A. R. da; Lemos,Paula H..
ABSTRACT This article explores decision analysis regarding Drop and Hook (D&H) transportation operations at sugarcane mills. By means of a case study, a combination of a discrete event simulation model and multi-attribute utility theory was used to evaluate different configurations for sugarcane delivery systems using internal, external, or no D&H systems. A D&H strategy maximises truck utilisation, as semi-trailers can be handled independently of the traction unit of the trucks, which makes the transport system more agile. For internal D&H systems the semi-trailer detaching/attaching point is located inside the mill site while for external D&H systems it is located outside, before the trucks’ weighbridge. Each configuration requires...

A hydrographic section from South Africa to the southern limit of the Antarctic Circumpolar Current at the Greenwich meridian ArchiMer
Gladyshev, S; Arhan, Michel; Sokov, A; Speich, Sabrina.
The properties and circulation of water masses leaving and entering the Atlantic Ocean south of Africa are examined using data from a hydrographic and Lowered acoustic Doppler current profiler section from South Africa to the southern limit of the Antarctic Circumpolar Current (ACC). At the upper levels, the ACC fronts are well determined using either classical water mass definitions or gradient-based criteria. While the locations of the Subantarctic Front (SAF), Polar Front (PF), and Southern ACC Front (SACCF) seem controlled by the neighbouring ridges, that of the Subtropical Front (STF) is much influenced in this region (similar to 10 degrees E) by northwestward propagating Agulhas rings. No large amount of Subantarctic Mode Water (SAMW) is observed,...

A Lagrangian Method to Isolate the Impacts of Mixed Layer Subduction on the Meridional Overturning Circulation in a Numerical Model ArchiMer
Thomas, Matthew; Treguier, Anne-marie; Blanke, Bruno; Deshayes, Julie; Voldoire, Aurore.
Large differences in the Atlantic meridional overturning circulation (AMOC) exhibited between the available ocean models pose problems as to how they can be interpreted for climate policy. A novel Lagrangian methodology has been developed for use with ocean models that enables a decomposition of the AMOC according to its source waters of subduction from the mixed layer of different geographical regions. The method is described here and used to decompose the AMOC of the Centre National de Recherches Météorologiques (CNRM) ocean model, which is approximately 4.5 Sv (1 Sv = 106 m3 s−1) too weak at 26°N, compared to observations. Contributions from mixed layer subduction to the peak AMOC at 26°N in the model are dominated by the Labrador Sea, which contributes...

A Software Package and Hardware Tools for in situ Experiments in a Lagrangian Reference Frame ArchiMer
Doglioli, Andrea; Nencioli, Francesco; Petrenko, Anne; Rougier, Gilles; Fuda, Jean-luc; Grima, Nicolas.
The Lagrangian Transport Experiment (LATEX) was developed to study the influence of coupled physical and biogeochemical dynamics at the meso- and submesoscales on the transfers of matter and heat between the coastal zone and the open ocean. One of the goals of the Latex10 field experiment, conducted during September 2010 in the Gulf of Lion (northwest Mediterranean), was to mark a dynamical mesoscale feature by releasing a passive tracer [sulfur hexafluoride (SF6)] together with an array of Lagrangian buoys. The goal was to release the tracer in an initial patch as homogeneous as possible in the horizontal, and to study its turbulent mixing and dispersion while minimizing the contribution due to advection. For that, it was necessary to continuously adjust...

Abundance and instantaneous transport of Petrolisthes armatus (Gibbes, 1850) planktonic larvae in the Catuama inlet, Northeast Brazil Anais da ABC (AABC)
Melo Júnior,Mauro de; Schwamborn,Ralf; Neumann-Leitão,Sigrid; Paranaguá,Maryse N..
The influence of tidal and diel changes on the exchange of Petrolisthes armatus planktonic larvae was studied at the Catuama inlet, which represents an intermediate system of marine and estuarine environments in the Northeast Brazil. To characterize the larval abundance and vertical distribution, samplings were carried out in August 2001 at neap tide and 3 stations, with 3 hours interval over 24 hours. Samples were taken at three or two depths at each station, with a plankton pump coupled to a 300 µm mesh size net. Petrolisthes armatus zoea I and II showed a mean of 26.3 ± 83.6 and 12 ± 38.8 ind m-3, respectively. During flood tides, the larvae were more concentrated in the midwater and surface, which avoided the transport to internal regions. In contrast,...

Agricultural markets in Benin and Malawi AgEcon
Fafchamps, Marcel; Gabre-Madhin, Eleni Z..
Based on original trader surveys, this paper examines how agricultural traders operate in Benin and Malawi. Results indicate that the largest transaction costs are search and transport. The use of modern technology is limited. Search methods rely principally on personal visits by the trader, and quality control requires the presence of the trader at the time of purchase. This increases costs, as the trader has to travel a lot, and makes it difficult for trading enterprises to grow. Since enterprises remain very small, personal transport and search time represent a non-negligible share of marketing costs.

Analysis of tidal and residual currents across semi-enclosed bay mouth based on shipboard ADCP measurements. OceanDocs
Li, Xibin; Sun, Xiaoyan; Yao, Zhigang.
Based on 25 hours shipboard ADCP measurements across semi-enclosed bay mouth(Kemen Channel), time series of tidal currents over 12 sites, which distribute evenly along the transect, were constructed to improve our understanding of tidal characteristics and residuals in this region. The tidal currents in Kemen Channel were identified as the regular semidiurnal and reversing tidal flows, with its behaviour more like standing waves. Moreover, the flood currents in the lower layers were found to be ahead of that in the upper layers and vice versa for ebb tides. The major of tidal ellipse for M2 constituent was found to be larger close to the southern side of the channel, with its incline also increasing toward the south. The signs of M4 constituent were also...

Anesthetic induction and recovery time of Centropomus parallelus exposed to the essential oil of Aloysia triphylla Ciência Rural
Parodi,Thaylise Vey; Santos,Celina Alcoforado dos; Veronez,Alexandra; Gomes,Levy de Carvalho; Heinzmann,Berta Maria; Baldisserotto,Bernardo.
ABSTRACT: This study analyzed the effectiveness of the essential oil of Aloysia triphylla (EOA) as an anesthetic and stress reducing agent in the transport of fat snook ( Centropomus parallelus ). Juveniles were exposed to different concentrations of EOA (seawater-adapted: 25-300μL L-1; freshwater-adapted: 200μL L-1) to identify the anesthetic induction and recovery times. In an additional experiment, seawater-adapted fat snook were transported in plastic bags with 10 or 20μL L-1 EOA for 6 or 24h. The increased concentration of EOA proportionally decreased the time required for anesthesia induction. Mortality was 30 and 70% in fat snook transported with 10 and 20µL L-1, respectively, 24h after transport. The addition of 20µL L-1 EOA significantly reduced...

Avaliação da viabilidade técnica e econômica da utilização de biomassas como fonte energética alternativa em fornos industriais AgEcon
Lima, Lilian Maluf de; Oliveira, Ana Maria Kefalas; Carletti, Paulo de Tarso Filho; Ferrari, Renata Cristina; Caixeta, Jose Vicente Filho.
This study, conducted along the year 2003, was held in the environment of a cement company plant located in the São Paulo State. That industry has used carbon black as predominant energetic source which besides resulting a huge emission of gases (CO and CO2) into the atmosphere, has been more expensive than some other alternatives of biomass sources. Taking into consideration the location of that plant, there was a large supply of available biomass to be used as alternative fuel for industrial ovens. Several biomasses were analyzed and it was concluded that the sugar cane bagasse and residues of wood (sawdust and woodchips) were the most appropriate alternatives to such an industry.

Capacidad de transporte de la constricción de Meninea para un flujo de dos capas y el efecto de la corriente de marea OceanDocs
Salinas, S.; Hormazábal, S..
En la primavera de 1995, se instaló un anclaje con dos correntómetros sobre el umbral de la constricción de Meninea para un análisis inicial de corrientes. El experimento fue parte del programa multidisciplinario Cimar 1 Fiordos. Durante 61 días se obtuvo las mediciones cada 30 minutos. Los correntómetros estaban instalados a 25 m y 40 m bajo la superficie del mar, en la profundidad de 60 m. La velocidad promedio fue de 15,9 cms-1 hacia el norte en el correntómetro superior y de 2,0 cms-1 hacia el sur en lo profundo. La variabilidad de las corrientes fue dominada por la corriente de marea de tipo semidiurno M2. Debido a la corriente de marea, crece la capacidad de transporte de la constricción con respecto al sistema de dos capas. El tiempo de residencia...

CONTRIBUIÇÃO DO SETOR DE TRANSPORTE NA ECONOMIA BRASILEIRA: UMA ABORDAGEM INSUMO-PRODUTO AgEcon
Sousa, Eliane Pinheiro de; Braga, Marcelo Jose.
O estudo buscou avaliar a contribuição do setor transporte para a economia brasileira. Especificamente, pretendeu-se determinar os setores capazes de propagar efeitos sistêmicos acima da média da economia como também mensurar os impactos econômicos na produção, emprego e renda, resultantes de alterações na demanda final. Para tal, utilizou-se o modelo de insumo-produto, já que este instrumental possibilita verificar as ligações entre os setores produtivos por meio dos índices de ligações de Rasmussen-Hirschman, campos de influência e índices puros de ligações, bem como determinar os efeitos de variações na demanda final sobre a produção, a renda e o emprego através das análises dos multiplicadores. Os resultados revelaram que o setor transporte não foi...

Deep Currents in the Rift Valley of the North Mid-Atlantic Ridge ArchiMer
Lahaye, Noe; Gula, Jonathan; Thurnherr, Andreas M.; Reverdin, Gilles; Bouruet-aubertot, Pascale; Roullet, Guillaume.
Over mid-ocean ridges, the interaction between the currents and the topography gives rise to complex flows, which drive the transport properties of biogeochemical constituents, and especially those associated with hydrothermal vents, thus impacting associated ecosystems. This paper describes the circulation in the rift valley along the Azores sector of the North Mid-Atlantic Ridge, using a combination of in-situ data from several surveys and realistic high-resolution modeling. It confirms the presence of a mean deep current with an up-valley branch intensified along the right inner flank of the valley (looking downstream), and a weaker down-valley branch flowing at shallower depth along the opposite flank. The hydrographic properties of the rift-valley...
