Joint environmental policy making and sustainable practices for the cardboard production: case study: Smurfit Kappa

Purpose – This paper presents an analysis of the influence of “Joint Environmental Policy-making” (JEP) in the operation of the company Smurfit Kappa (SK) in The Netherlands, Austria and Denmark (NL&AD). The paper aims to answer the question: to what extend has different levels of jointness and voluntariness of cardboard packaging-chain agreements between federal, governmental and business actors led to different recycling performances within the same company? Design/methodology/approach – JEP's analysis was framed under the model described by Mol, Volkmar and Liefferink by using information from mixed-methods throughout a semi-structured questionnaire for interviews and revision of relevant secondary data. This is a case of cross-national comparison for which origin and implementation level of JEPs were described per country, in accordance with those stages of the cardboard production chain. Findings – Jointness and voluntariness amongst other actors from governmental areas and business ranked high for the Dutch packaging-chain agreements with a visible impact in SK's recycling rates. SK in Austria and in Denmark, in this order, had a lower implementation level of JEPs which could be reflected in a lower recycling performance than in the Dutch SK subsidiaries. The context matters, including both political and social conditions. In particular, the role of householders as a last link in the recycling chain. Based on this, the selected countries share some societal characteristics associated with the environmental public awareness and active social participation. Originality/value – This paper fulfills an analysis of how environmental policy making is affected by the country context within the same company

Vortex pinning by intrinsic correlated defects in Fe1-ySe

We present a study on the transport and magnetic properties of superconducting Fe1-ySe single crystals. In the superconducting state, the in-plane electrical resistivity of the crystal is measured for fields up to 16 T and as a function of field direction, in order to understand how the vortex dynamics is affected by the presence of defects. A strong deviation from the slightly anisotropic crystal (electronic anisotropy constant 7 ~ 1.08) is observed as a steep angular dependence, which is interpreted as a signature of the presence of correlated defects. The influence of the correlated defects on the critical current is studied through the angular dependence of the magnetization, and compared to numerical simulations

Hadron-nucleon Total Cross Section Fluctuations from Hadron-nucleus Total Cross Sections

The extent to which information about fluctuations in hadron-nucleon total cross sections in the frozen approximation can be extracted from very high energy hadron-nucleus total cross section measurements for a range of heavy nuclei is discussed. The corrections to the predictions of Glauber theory due to these fluctuations are calculated for several models for the distribution functions, and differences of the order of 50 mb are found for heavy nuclei. The generating function for the moments of the hadron-nucleon cross section distributions can be approximately determined from the derivatives of the hadron-nucleus total cross sections with respect to the nuclear geometric cross section. The argument of the generating function, however, it limited to the maximum value of a dimensionless thickness function obtained at zero impact parameter for the heaviest nuclear targets: about 1.8 for pions and 3.0 for nucleons.Comment: 14 pages, revtex 3.0, 4 figures available upon reques

State transfer in dissipative and dephasing environments

By diagonalization of a generalized superoperator for solving the master equation, we investigated effects of dissipative and dephasing environments on quantum state transfer, as well as entanglement distribution and creation in spin networks. Our results revealed that under the condition of the same decoherence rate $\gamma$, the detrimental effects of the dissipative environment are more severe than that of the dephasing environment. Beside this, the critical time $t_c$ at which the transfer fidelity and the concurrence attain their maxima arrives at the asymptotic value $t_0=\pi/2\lambda$ quickly as the spin chain length $N$ increases. The transfer fidelity of an excitation at time $t_0$ is independent of $N$ when the system subjects to dissipative environment, while it decreases as $N$ increases when the system subjects to dephasing environment. The average fidelity displays three different patterns corresponding to $N=4r+1$, $N=4r-1$ and $N=2r$. For each pattern, the average fidelity at time $t_0$ is independent of $r$ when the system subjects to dissipative environment, and decreases as $r$ increases when the system subjects to dephasing environment. The maximum concurrence also decreases as $N$ increases, and when $N\rightarrow\infty$, it arrives at an asymptotic value determined by the decoherence rate $\gamma$ and the structure of the spin network.Comment: 12 pages, 6 figure

Variability of prey preferences and uptake of anthropogenic particles by juvenile white seabream in a coastal lagoon nursery ground

Marine plastic litter, originating from land-based sources, enters the marine environment by passing through coastal ecosystems such as lagoons and estuaries. As early life history stages (ELHS) of many commercially important fish species rely on these transitional areas as nursery grounds, we hypothesized that they encounter a spatial gradient of habitat quality and pollution from inner to outer parts of their vital environment. With sizes < 5 mm, anthropogenic particles (AP), among them microplastic (MP) fibers and fragments, entail a high bioavailability for ELHS of fish, potentially facilitating AP uptake at early developmental stages which may have implications for their survival and growth. This study provides a contextualization baseline between feeding preferences and uptake of AP by the white seabream Diplodus sargus (Linnaeus, 1758) in an estuarine nursery ground on the southern coast of Portugal. Juvenile fish showed a generalized, omnivorous feeding mode with differences in trophic resource utilization between individuals collected at distinct seagrass meadows in the lagoon. A total of 23.13% of the fish (n = 147) were detected with AP in the gastrointestinal tract, and the mean number of AP per AP-feeding individual was 1.64 +/- 1.04, with anthropogenic fibers (n = 47) occurring more frequently than fragments (n = 9). Knowledge of the underlying factors for MP ingestion will be greatly enhanced by considering environmental conditions along with species-stage and life-stage specific feeding modes and prey preferences which shape the uptake probability of anthropogenic fibers and fragments.LA/P/0101/2020info:eu-repo/semantics/publishedVersio
