Scenarios are employed to address a large number of future environmental and socioeconomic challenges. We present a conceptual framework for the development of scenarios to integrate the objectives of different stakeholder groups. Based on the framework, land-use scenarios were developed to provide a common base for further research. At the same time, these scenarios assisted regional stakeholders to bring forward their concerns and arrive at a shared understanding of challenges between scientific and regional stakeholders, which allowed them to eventually support regional decision making. The focus on the integration of views and knowledge domains of different stakeholder groups, such as scientists and practitioners, required rigorous and repeated...

High performance liquid chromatographic screening and gas chromatography-nass spectrometry confirmation of tebuthiuron residues in drinking water.
Provedor de dados: 14
Autores: BONATO, P. S.; LANCHOTE, V. L.; DREOSSI, A. de C.
Tebuthiuron (N-[5-(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl]-N,N-dimethylurea) is a phenylurea herbicide used in sugar cane culture for the pre- and post-emergence control of weeds [1,2]. Analysis of tebuthiuron (Figure 1) and of other phenylurea herbicides in environmental samples can be performed by HPLC [3-10], or by gas chromatography using selective detectors such as nitrogen-prosphorus detector (NPD), eletron-capture detector (ECD), or a mass spectrometer (MS) [11-16]. Although Loh et al [17] reported that the use of temperatures above 280oC permits quantitative tebuthiuron breakdown, thus permitting the analysis of the products of decomposition formed, methods based on gas chromatography usually involve a derivatization step to permit analysis of...

Cold storage of Pacific oysters out of water: biometry, intervalval water and sensory assessment
Provedor de dados: 5
Autores: Buzin, Florence; Baudon, Violaine; Cardinal, Mireille; Barille, Laurent; Haure, Joel.
Due to the important economic activity of oyster production in France, microalgal toxic events represent a significant constraint for shellfish farmers who face closures of bivalve production-sites. The frequency of closures of 3 weeks or less represents half of the total closures along the French coasts. Cold storage could be a simple and affordable solution for temporary and short-term storage before commercialisation. A stock of marketable Pacific oyster Crassostrea gigas was therefore stored during 22 days in non-immersed conditions at 3 degrees C with 100% humidity. At the end of the experiment, the oyster mortality rate remained at a low level of less than 3.5%. The sensory attributes, odour, appearance, texture and flavour, did not show significant...

Quality-control tests for OC4, OC5 and NIR-red satellite chlorophyll-a algorithms applied to coastal waters
Provedor de dados: 5
Autores: Lavigne, H.; Van Der Zande, D.; Ruddick, K.; Cardoso Dos Santos, J.f.; Gohin, Francis; Brotas, V.; Kratzer, S.
Reliable satellite estimates of chlorophyll-a concentration (Chl-a) are needed in coastal waters for applications such as eutrophication monitoring. However, because of the optical complexity of coastal waters, retrieving accurate Chl-a is still challenging. Many algorithms exist and give quite different performance for different optical conditions but there is no clear definition of the limits of applicability of each algorithm and no clear basis for deciding which algorithm to apply to any given image pixel (reflectance spectrum). Poor quality satellite Chl-a data can easily reach end-users. To remedy this and provide a clear decision on when a specific Chl-a algorithm can be used, we propose simple quality control tests, based on MERIS water leaving...

Are hake otolith macrostructures randomly deposited? Insights from an unsupervised statistical and quantitative approach applied to Mediterranean hake otoliths
Provedor de dados: 5
Autores: Courbin, Nicolas; Fablet, Ronan; Mellon-duval, Capucine; De Pontual, Helene.
Individual fish age data are crucial to fish stock assessment, so their accuracy and precision are vital. The acquisition of age data most often relies on interpreting fish otoliths, a complex task in which expert subjectivity increases with the complexity of the structural patterns of the otoliths. The question arises for certain fish species (e.g. hake, Merluccius merluccius) whether the deposition of otolith macrostructures is meaningful for age estimation. A quantitative method based on the evaluation of otolith similarity in terms of structural patterns is presented to investigate this issue. It relies on the determination of a typology of otolith macrostructures from an unsupervised statistical analysis of the distributions of their characteristics....

Leishmaniasis is a neglected disease endemic in five continents. It is a severe disease that may lead to death, and its early detection is important to avoid severe damage to affected individuals. Molecular methods to detect Leishmania are considered alternatives to overcome the limitations presented by conventional methods. The aim of this study was to develop multiplex PCR systems able to detect small amounts of target DNA of Leishmania infantum and Leishmania braziliensis, and the gene coding for glyceraldehyde-3-phosphate dehydrogenase (G3PD) in mammals, enabling quality evaluation of the sample simultaneously with detection of the specific target. The systems created for G3PD recognition were combined with detection systems for L. infantum and L....

Among other results, it was found that when hake is handied property it maintains good quality levels up to 10 days after catch, irrespective of season. Its total storage life in boxes with ice is approximately two weeks. Although total storage life remained unchanged, it was found that quality levels tended to be significantly higher if overfilling of boxes was avoided, if the fish was gutted immediately after catch, or if hake was stored in containers with seawater.

Autores: Chalén, F.; Sáenz, J.; Cambisaca, M.; Franco, F.
In aquaculture are used various drugs and chemicals for veterinary use to prevent or treat diseases, control pests, help production processes and promote growth. These substences are usually incorporated in the so-called feed. Hence, the unregulated use of ingredientes in different formulations as preservatives and dyes may also cause a risk in food safety. The National Fisheries Institute monitor the waste coming from drugs, to comply with international market requirements in relation to quality standards. Residues of Malachite Green (MV) and Malachite Leucoverde (LMV) were in 82 samples of fish meal, shrimp and squid, balanced, nutritional substances in different forms granules, pastes and powders, vitamins, desinfectants, fungicides and medicated...

Un estudio de histamina en Dorado MAHI-MAHI Coryphaena hippurus y su relación con la calidad de producto de la pesca ecuatoriana

Autores: Bostock, T.; Barratt, A.; Camba, N.
El presente trabajo llama la atención a las recientes epidemias de intoxicación histamínicas reportadas en los Estados Unidos, debido al consumo del dorado (Coryphaena hippurus) o Mahi-Mah, contaminado. Esto dió como resultado la prohición de las importaciones de esta especie, proveniente de varios países entre ellos el Ecuador, y siendo el dorado una especie de relativa importancia económica en este país, dicha prohibición ha preocupado al sector pesquero. Los estudios llevados a cabo muestran claramente la susceptibilidad de esta especie a desarrollar histamina. Esto se debe principalmente a la temperatura a la que está expuesta, pues la demora antes de enhielar el pescado es la etapa crítica. Los resultados muestran un aumento exponencial de los niveles...

Variation in egg and larval quality in various fish and crustacean species
Provedor de dados: 27
Autores: Lavens, P.; Sorgeloos, P.
It is generally accepted, that a major constraint in the further development of marine fish and crustacean aquaculture, is the variable quality of eggs and larvae used for the hatchery-production of fry. Nonetheless, valid criteria to evaluate optimal egg quality have not been identified yet. Instead, particular indicators, are used, e.g. the fertilization and hatching rate, overall culture success during the first rearing period, etc., but these are not totally objective because hatchery-specific conditions may interfere. The biochemical composition of the egg may be one of the possible determinants of egg quality, which can be evaluated on a more objectie basis. In this respect, studied have been initiated to analyze in freshly-released eggs, the levels...

Meiobenthos as a tool in the assessment of marine environmental quality
Provedor de dados: 27
Autores: Heip, C.H.R.
The assessment of the impact of pollution on the marine environment depends on the possibility of prediction either by comparison or more ideally by the analysis of time series which are long enough. Obtaining data for the construction of these time series should be one of the principal goals of monitoring. Parameters which are measured should have a low variability in time and in space or low frequency. The analysis of meiobenthic communities in the North Sea and the adjacent estuaries shows that harpacticoid copepods are especially suitable as the number and the nature of the species are stable and density, biomass, and diversity are characterized by the absence of variance in the high frequencies. Nematodes, though overwhelmingly abundant, are more...

A simple test for quality evaluation of cultured fry of marine fish
Provedor de dados: 27
Autores: Dhert, P.; Lavens, P.; Sorgeloos, P.
A stress test is proposed for the evaluation of the physiological condition of fish larvae in nutritional studies. The test was used in a study of quantitative (n-3) highly unsaturated fatty acids (HUFA) requirements in larval &lt;i&gt;Lates calcarifer&lt;/i&gt; and &lt;i&gt;Siganus guttatus&lt;/i&gt;. It enabled to suggest fast intervention at reduced larval quality and allowed to prevent mass mortalities. The stress test offered valuable information for the quantification study of fatty acid requirements in marine fish larvae. In &lt;i&gt;Lates&lt;/i&gt; demands for fatty acids were detected in metamorphosis. In &lt;i&gt;Siganus&lt;/i&gt; on the other hand, the sensitivity of the larvae was considerably reduced after short (n-3) HUFA boosting of the...

Autores: Luten, J.; Bouquet, W.; Oehlenschläger, J.; Meetschen, U.; Etienne, M.; Stroud, G.; Bykowski, P.; Batista, I.; Vyncke, W.; Stefansson, G.
Eight WEFTA laboratories participated in two series of intercomparison exercises on sulfite determination in tropical shrimps. Samples of tropical shrimps were spiked with sodium metabisulfite (Na&lt;sub&gt;2&lt;/sub&gt;S&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;5&lt;/sub&gt;) and hydroxymethylsulfonate (HMS) at a level of 25-90 mg SO&lt;sub&gt;2&lt;/sub&gt;/kg. Most of the laboratories determined the sulfite content with (modified) methods of Monier-Williams or De Vries et al. The overall mean recovery of sulfite was rather low (47-60%), which may be attributed to an irreversible reaction of sulfite with the tropical shrimps. The repeatability of the methods within the participating laboratories was good. However, reproducibility among the laboratories was...

Autores: Velthuis,   Annet G.J.; Reij,   M.W.; van Wagenberg,   Coen P.A.
The relation between the moment at which a recall of Dutch custard is initiated and the direct costs of this recall was investigated. A simulation model of the custard supply chain was developed to compare scenarios with and without a quarantine of 48 h at the storage of the production plant. The model consists of three parts; first the distribution of a 24,000 L batch of custard over the supply chain over time is simulated, second the time to detect spoilage bacteria with a recontamination test procedure is simulated, third the direct recall costs of custard over the different parts of the supply chain are calculated. Direct recall costs increase from about €25,000 per batch to €36,171 from 57 to 135 h in the situation without quarantine and from €25,000...

Autores: Mau,   Markus.
The development in food network perspective forces the demand for a proper configuration of the risks that occur from the ongoing trend towards the globalized supply chain. The paper shows the requirement shift through globalized procurement. As an effect towards long distance purchasing activities the direct control of production, logistics processes and processing are out of direct control for most of the person in charge in downstream processes. Process transparency and information readiness are essential to reduce risk in (e-)business networks. Outputs of this requirement are vertical coordinations through interorganizational agencies as EurepGap and IFS. Especially for brand marks relationship management and vertical coordination are needed to secure...

Autores: Melo,Rafaela Paula; Albiero,Daniel; Praciano,Aline Castro; Monteiro,Leonardo de Almeida; Garcia,Angel Pontin.
ABSTRACT Family farming seeks to use less-aggressive agricultural practices, however, there is little machinery available that is suitable for the reality of this sector. This has led to the use of technically incorrect practices, which have contributed to the impoverishment, compaction and desertification of agricultural soils. Punch seeders are seen as a promising alternative for carrying out sowing in family farming, as they employ localised seed distribution with less disturbance of the soil and the consequent preservation and conservation of its structure. The aim of this study was to evaluate the quality of seed distribution by a punch seeder used in family farming. The experiment was carried out in a soil classified as a Red-Yellow Argisol....

Autores: Funasaki,Mariko; Menezes,Ingrid Sabino; Barroso,Hiléia dos Santos; Zanotto,Sandra Patricia; Carioca,Cláudia Regina Ferreira.
The tocopherol content of Brazil nut oil from different Amazon regions (Manicoré-AM, Rio Preto da Eva-AM, São João da Baliza-RR, Caroebe-RR, Belém-PA, and Xapurí-AC) was investigated by normal-phase high-performance liquid chromatography. For all authentic oils, two isomers: α- and γ-tocopherols were observed (37.92-74.48 µg g-1, 106.88-171.80 µg g-1, respectively), and their levels were relatively constant among the oils having these geographic origins, which would enable to distinguish Brazil nut oil from other plant oils for authentication purposes. Commercial Brazil nut oils were also evaluated, and some of these oils demonstrated a tocopherol content that was very different from that of the authentic oils. Therefore, we suggest that the tocopherol...

The standardization of requeijão cheese quality characteristics is a processing stage which is directly influenced by the chemical composition of the raw material. Fat and water concentrations are the main factors that cause variation in quality properties of the requeijão and, when not thoroughly controlled, may cause a lack in standardization of the food. Calculations of ingredients for effective standardization must be made in relation to the final product through of iterative calculations, which makes the manual process unfeasible. Thus, the objective of the present study was to develop a spreadsheet for ingredient calculation, with restrictions being the different concentrations of fat and water in order to standardize the final products.

The aim of this study was to find alternatives to reduce the cost of mass production of the South American fruit fly (A. fraterculus) by looking for locally available products as protein source in the diet of adults to replace the imported product without changing the quality parameters. Two yeast from a Brazilian company were evaluated. The quality parameters showed that the imported hydrolyzed yeast used in the adult diet could be perfectly replaced by the local products tested, with a reduction of over 80% of the cost of the diet. The quality of the produced insects remained the same and there were improvements in some quality parameters such as the volume of eggs produced, number of adults flying and longevity under the stress.

Alternative chromatographic system for the quality control of lipophilic technetium-99m radiopharmaceuticals such as [99mTc(MIBI)6]+
Provedor de dados: 56
Autores: Faria,D.P.; Buchpiguel,C.A.; Marques,F.L.N.
Knowledge of the radiochemical purity of radiopharmaceuticals is mandatory and can be evaluated by several methods and techniques. Planar chromatography is the technique normally employed in nuclear medicine since it is simple, rapid and usually of low cost. There is no standard system for the chromatographic technique, but price, separation efficiency and short time for execution must be considered. We have studied an alternative system using common chromatographic stationary phase and alcohol or alcohol:chloroform mixtures as the mobile phase, using the lipophilic radiopharmaceutical [99mTc(MIBI)6]+ as a model.

Provedor de dados: 56
Autores: Calixto,J.B.
This review highlights the current advances in knowledge about the safety, efficacy, quality control, marketing and regulatory aspects of botanical medicines. Phytotherapeutic agents are standardized herbal preparations consisting of complex mixtures of one or more plants which contain as active ingredients plant parts or plant material in the crude or processed state. A marked growth in the worldwide phytotherapeutic market has occurred over the last 15 years. For the European and USA markets alone, this will reach about $7 billion and $5 billion per annum, respectively, in 1999, and has thus attracted the interest of most large pharmaceutical companies. Insufficient data exist for most plants to guarantee their quality, efficacy and safety. The idea that...

Autores: Cantarelli,Vlademir Vicente; Inamine,Everton; Brodt,Teresa Cristina Zenobin; Secchi,Carina; Pereira,Fabiana de Souza; Amaro,Maria Cristina; Batalha,Alice Aurora; Ligiero,Simone Dornellas.
Stringent quality control protocols must be used in order to guaranty that a particular medium is able to recover all sort of organism that may be present in clinical samples. Our aim was to evaluate an alternative protocol that would allow us to detect medium failure to yield quantitative growth of selected pathogens, and compare with the document M22-A2 from NCCLS. The detection limit of Haemophilus influenzae was significantly different depending on media source. We conclude that for some fastidious microorganisms, quantitative verification of the growth capacity of the culture medium is advised.

Simvastatin is commercially available as tablets and compounded capsules in Brazil. Very few reports regarding these capsules' quality, and consequently their efficacy, are available. The pharmaceutical quality of 30 batches of 20 mg simvastatin capsules from the market was evaluated by weight determination, content uniformity, disintegration (Brazilian Pharmacopeia), assay and dissolution test (USP32 tablet monograph). A HPLC method was developed for assay, content uniformity and dissolution test, and specifications were also established. Out of the 30 batches evaluated, 29 showed capsule disintegration within 45 min and individual weight variation was within ±10% or ±7.5% relative to average weight, for &lt; or &amp;gt; 300 mg, respectively. Only 27...
