Notoriedade dos produtos tradicionais de origem animal (DOP e IGP) do Alentejo

O presente trabalho visa conhecer o nível de notoriedade dos produtos tradicionais de origem animal (DOP e IGP) do Alentejo no mercado consumidor. Este objectivo foi alcançado através da realização de revisão bibliográfica com recurso às fontes secundárias disponíveis e de fontes primárias, nomeadamente de um questionário de avaliação da notoriedade dos produtos tradicionais (DOP e IGP) de origem animal do Alentejo expressamente desenvolvido para o efeito. A informação obtida permitiu caracterizar a oferta dos produtos tradicionais de origem animal do Alentejo, em termos quantitativos, qualitativos e diversidade, enquadrar teoricamente o tema da notoriedade no contexto do comportamento do consumidor e do marketing agro-alimentar e identificar os procedimentos metodológicos a serem utilizados e delineamento do trabalho de investigação. A análise dos dados recolhidos por inquérito, tratados com recurso a software e técnicas estatísticas descritivas, permitiram retirar conclusões relevantes, tais como a baixa notoriedade dos produtos DOP e IGP, o produto com mais notoriedade, Top-of-Mind, a Carnalentejana, entre outros. Foram identificados tanto nas fontes primárias como nas secundárias aspectos em comum: uma baixíssima notoriedade dos produtos certificados e uma preocupação e necessidade em haver mais acções de divulgação destes produtos. Dos 33 produtos certificados de origem animal do Alentejo, apuraram-se que apenas 26 se encontram a ser comercializados e em que muitos casos os agrupamentos remetem para os produtores a responsabilidade da promoção dos produtos. Foram ainda identificados tópicos para futuras pesquisas e para acções de marketing tendentes a melhorar a notoriedade dos produtos tradicionais de origem animal do Alentejo no mercado. ABSTRACT; The present work aims to know the level of renown of the traditional products of animal origin (DOP and IGP) of the Alentejo in the consumer market. This objective was reached through the realization of bibliographical revision with resource to the available secondary fountains and of primary fountains, namely of a questionnaire of evaluation of the renown of the traditional products (DOP and IGP) of animal origin of the Alentejo definitely developed for the effect. The obtained information allowed to characterize the offer of the traditional products of animal origin of the Alentejo, in quantitative, qualitative terms and diversity, to fit theoretically the subject of the renown in the context of the behavior of the consumer and of the food-rough marketing and to identify the methodological proceedings being used and delineation of the work of investigation. The analysis of the data gathered by inquiry, treated with resource the software and descriptive statistical techniques, allowed there withdrew relevant conclusions, such as the low renown of the products DOP and IGP, the product with more renown, Top-of-Mind, was the Carnalentejana, between others. Aspects were identified so much in the primary fountains how in secondary in common: a low renown of the certified products and a preoccupation and necessity in having more actions of spread/promotion of these products. Of 33 products made sure of animal origin of the Alentejo, they perfected that you punish 26 they are being marketed and in what many cases the groupings send for the producers the responsibility of the promotion of the products. Topics were still identified for future inquiries and for tending actions of marketing to improve the renown of the traditional products of animal origin of the Alentejo in the market.

Development of the sustainable building and construction products industry in Australia

This paper draws on a major study the authors conducted for the Australian Government in 2009. It focuses on the diffusion issues surrounding the uptake of sustainable building and construction products in Australia. Innovative sustainable products can minimise the environmental impact during construction, while maximising asset performance, durability and re-use. However, there are significant challenges faced by designers and clients in the selection of appropriate sustainable products in consideration of the integrated design solution, including overall energy efficiency, water conservation, maintenance and durability, low-impact use and consumption. The paper is a review of the current state of sustainable energy and material product innovations in Australia. It examines the system dynamics surrounding these innovations as well as the drivers and obstacles to their diffusion throughout the Australian construction industry. The case product types reviewed comprise: solar energy technology, small wind turbines, advanced concrete technology, and warm-mixed asphalt. The conclusions highlight the important role played by Australian governments in facilitating improved adoption rates. This applies to governments in their various roles, but particularly as clients/owners, regulators, and investors in education, training, research and development. In their role as clients/owners, the paper suggests that government can better facilitate innovation within the construction industry by adjusting specification policies to encourage the uptake of sustainable products. In the role as regulators, findings suggest governments should be encouraging the application of innovative finance options and positive end-user incentives to promote sustainable product uptake. Also, further education for project-based firms and the client/end users about the long-term financial and environmental benefits of innovative sustainable products is required. As more of the economy’s resources are diverted away from business-as-usual and into the use of sustainable products, some project-based firms may face short-term financial pain in re-shaping their businesses. Government policy initiatives can encourage firms make the necessary adjustments to improve innovative sustainable product diffusion throughout the industry.

Direct detection of additives and degradation products from polymers by liquid extraction surface analysis employing chip-based nanospray mass spectrometry

RATIONALE: Polymer-based surface coatings in outdoor applications experience accelerated degradation due to exposure to solar radiation, oxygen and atmospheric pollutants. These deleterious agents cause undesirable changes to the aesthetic and mechanical properties of the polymer, reducing its lifetime. The use of antioxidants such as hindered amine light stabilisers (HALS) retards these degradative processes; however, mechanisms for HALS action and polymer degradation are poorly understood. METHODS: Detection of the HALS TINUVINW123 (bis(1-octyloxy-2,2,6,6-tetramethyl-4-piperidyl) sebacate) and the polymer degradation products directly from a polyester-based coil coating was achieved by liquid extraction surface analysis (LESA) coupled to a triple quadrupole QTRAPW 5500 mass spectrometer. The detection of TINUVINW123 and melamine was confirmed by the characteristic fragmentation pattern observed in LESA-MS/MS spectra that was identical to that reported for authentic samples. RESULTS: Analysis of an unstabilised coil coating by LESA-MS after exposure to 4 years of outdoor field testing revealed the presence of melamine (1,3,5-triazine-2,4,6-triamine) as a polymer degradation product at elevated levels. Changes to the physical appearance of the coil coating, including powder-like deposits on the coating's surface, were observed to coincide with melamine deposits and are indicative of the phenomenon known as polymer ' blooming'. CONCLUSIONS: For the first time, in situ detection of analytes from a thermoset polymer coating was accomplished without any sample preparation, providing advantages over traditional extraction-analysis approaches and some contemporary ambient MS methods. Detection of HALS and polymer degradation products such as melamine provides insight into the mechanisms by which degradation occurs and suggests LESA-MS is a powerful new tool for polymer analysis.

Open and closed-loop recycling of textile and apparel products

Textile waste is a significant contributor to landfill yet the majority of textiles can be recycled, allowing for the energy and fibre to be reclaimed. This chapter examines the open-loop and closed loop recycling of textile products with particular reference to the fashion and apparel context. It describes the fibres used within apparel, the current mechanical and chemical methods for textile recycling, LCA findings for each method, and applications within apparel for each. Barriers for more effective recycling include ease of integration into existing textile and apparel design methods as well as coordinated collection of post-consumer waste. The chapter concludes with a discussion of innovations that point to future trends in both open-loop and closed-loop recycling within the apparel industry.

Prevalence, persistence and control of Salmonella and Listeria in shrimp and shrimp products: A review.

Shrimp are an important commodity in the international fisheries trade and there is an indication of an increase in worldwide consumption of this crustacean. Salmonella and Listeria have been isolated from shrimps and shrimp products on a regular basis since the 1980s. The continued reporting of the presence of these pathogens in fresh and frozen shrimps, and even in the lightly preserved and ready-to-eat products, indicates that the existing practices used by the manufacturers or processors are insufficient to eliminate these pathogens. This paper reviews the information available on Salmonella and Listeria in shrimp and makes recommendations on control options and avenues for future research in order to improve shrimp safety and quality.

Biorefineries – creating economic opportunities from biofuels and bio-products

Biorefineries, producing fuels, green chemicals and bio-products, offer great potential for improving the profitability and sustainability of tropical agricultural industries. Biomass from tropical crops like sugarcane, sweet sorghum, palm and cassava offer great potential because of the high biomass growth potential under favourable climatic conditions. Biorefineries aim to convert waste residues through biochemical and enzymatic processes to low cost fermentable sugars which are a platform for value-adding. Through subsequent fermentation utilising microbial biotechnologies or chemical synthesis, the sugars can be converted to fuels including ethanol and butanol, oils, organic acids such as lactic and levulinic acid and polymer precursors. Other biorefinery products can include food and animal feeds, plastics, fibre products and resins. Pretreatment technologies are a key to unlocking this potential and new technologies are emerging. This paper will address the opportunities available for tropical biorefineries to contribute to the future profitability of tropical agricultural industries. The importance of pretreatment technologies will be discussed.

Rainbow Connection Number of Graph Power and Graph Products

Rainbow connection number, rc(G), of a connected graph G is the minimum number of colors needed to color its edges so that every pair of vertices is connected by at least one path in which no two edges are colored the same (note that the coloring need not be proper). In this paper we study the rainbow connection number with respect to three important graph product operations (namely the Cartesian product, the lexicographic product and the strong product) and the operation of taking the power of a graph. In this direction, we show that if G is a graph obtained by applying any of the operations mentioned above on non-trivial graphs, then rc(G) a parts per thousand currency sign 2r(G) + c, where r(G) denotes the radius of G and . In general the rainbow connection number of a bridgeless graph can be as high as the square of its radius 1]. This is an attempt to identify some graph classes which have rainbow connection number very close to the obvious lower bound of diameter (and thus the radius). The bounds reported are tight up to additive constants. The proofs are constructive and hence yield polynomial time -factor approximation algorithms.

20th annual meeting of the WEFTA Working Group on Analytical Methods in Fish and Fishery Products and 3rd annual meeting of the WEFTA Working Group on Microbiology. A retrospect on 20 years

After 20 annual meetings it is worth to have a look back and to see how it has started. There has been very little collaboration on research projects between member institutes under the auspices of WEFTA, co-operation in more neutral areas of common interest was developed at an early stage. The area which has proved very fruitful is methodology. It was agreed that probably the best way to make progress was to arrange meetings at each laboratory in turn where experienced, practising scientists could describe in detail how they carried out analyses. In this way, difficulties could be demonstrated or uncovered, and the accuracy, precision, efficiency and cost of the methods used in different laboratories could be compared.
