Ecosystem indicators for measuring industrial symbiosis

Industrial symbiosis (IS) is a collaborative approach among firms involving physical exchanges of materials, energy, and wastes, which creates economic advantages for firms and environmental benefits for the society. In this paper, we adopt an ecosystem approach to conceptualize the network of firms involved in IS relationships (ISN), in terms of organisms (firms), functions (waste exchange), and services (environmental benefits), and provide new insight on how to assess and compute IS performance indicators. In particular, we designed five classes of indicators aimed at assessing 1) the impact of services provided by ISNs on the environment, 2) the performance of the ISN services, 3) how the single functions contribute to ISN services, 4) the performance of the ISN functions, and 5) how the single firms contribute to ISN functions. A numerical example is also discussed showing how to compute them and the information they provide. The proposed indicators are useful to develop proper strategies to increase the efficiency of the system in exploiting the IS synergies, to improve the symbiotic exchanges carried out in ISNs, and to identify firms contributing most to IS benefits. Hence, they may assist managers of ISNs and policymakers in decision-making aspects, an urgent need of the literature

Distinct magnetic signatures of fractional vortex configurations in multiband superconductors

Vortices carrying fractions of a flux quantum are predicted to exist in multiband superconductors, where vortex core can split between multiple band-specific components of the superconducting condensate. Using the two-component Ginzburg-Landau model, we examine such vortex configurations in a two-band superconducting slab in parallel magnetic field. The fractional vortices appear due to the band-selective vortex penetration caused by different thresholds for vortex entry within each band-condensate, and stabilize near the edges of the sample. We show that the resulting fractional vortex configurations leave distinct fingerprints in the static measurements of the magnetization, as well as in ac dynamic measurements of the magnetic susceptibility, both of which can be readily used for the detection of these fascinating vortex states in several existing multiband superconductors.Comment: 5 pages, 4 figure

Generalizing the DGLAP Evolution of Fragmentation Functions to the Smallest x Values

An approach which unifies the Double Logarithmic Approximation at small x and the leading order DGLAP evolution of fragmentation functions at large x is presented. This approach reproduces exactly the Modified Leading Logarithm Approximation, but is more complete due to the degrees of freedom given to the quark sector and the inclusion of the fixed order terms. We find that data from the largest x values to the peak region can be better fitted than with other approaches.Comment: 10 pages, 3 figure

Effects of Different Dietary Levels of Two Types of Olive Pulp and Exogenous Enzyme Supplementation on the Gastrointestinal tract size, Immunology and Hematology of Broilers Author(s) Sayehban P I Seidavi A II Dadashbeiki M II Ghorbani A III Araújo WAG

ABSTRACT The effects of the dietary inclusion of olive pulp (OP) and the supplementation of a commercial enzyme blend (ENZ) on the gastrointestinal tract (GIT) size, and immune and hematological parameters were evaluated. In total, 600 one-day-old Ross 308 male broiler chicks were divided into 6 treatments according to a completely randomized design, in a 2×2×2 factorial scheme, consisting of the dietary inclusion of two olive pulp levels (50 and 100 g/kg in diet), two pulp categories (processed and unprocessed), and the inclusion or not of an enzyme blend. On d 42, birds were euthanized and blood samples were collected, and lymphoid, hematologic, and GIT organs were measured. The inclusion of 100g/kg OP in the diets increased jejunum relative weight (J%) and jejunum length (p ≤ 0.05). Processed OP reduced jejunum weight and length, J%, and left cecum length, serum triglycerides and VLDL cholesterol levels (p ≤ 0.05). Enzyme supplementation did affect any of the studied parameters (p>0.05). The OP inclusion improved the GIT size, while processed OP reduced GIT measurements and serum lipid levels

Caracterização química de azeites elementares da região de Trás-os-Montes.

Trás-os-Montes é uma das principais regiões produtoras de azeite a nível nacional, onde é produzido azeite com a Denominação de Origem Protegida “Azeite de Trás-os-Montes”. De uma forma geral, estes azeites resultam de uma mistura de diferentes cultivares, maioritariamente Cobrançosa, Madural e Verdeal Transmontana, sendo permitida a presença de outras, ainda que em menor proporção. Com o presente trabalho pretendeu-se contribuir para a caracterização química de azeites elementares produzidos na região de Trás-os-Montes. Assim, foram analisadas 80 amostras de azeite das cultivares Cobrançosa (20), Verdeal Transmontana (11), Madural (11), Santulhana (11), Negrinha de Freixo (11), Cordovil (10), Borrenta (2), Bical (1), Cordovesa (1), Lentisca (1) e Madural Negra (1), num total de 11 cultivares, tendo sido caracterizados no que respeita à acidez, índice de peróxidos, absorvência no ultravioleta, teor em clorofilas e carotenóides e composição em ácidos gordos
