description: We study the dark energy equation of state as a function of redshift in a non-parametric way, without imposing any {\it a priori} $w(z)$ (ratio of pressure over energy density) functional form. As a check of the method, we test our scheme through the use of synthetic data sets produced from different input cosmological models which have the same relative errors and redshift distribution as the real data. Using the luminosity-time $L_{X}-T_{a}$ correlation for GRB X-ray afterglows (the Dainotti et al. correlation), we are able to utilize GRB sample from the {\it Swift} satellite as probes of the expansion history of the Universe out to $z \approx 10$. Within the assumption of a flat FLRW universe and combining SNeIa data with BAO constraints, the resulting maximum likelihood solutions are close to a constant $w=-1$. If one imposes the restriction of a constant $w$, we obtain $w=-0.99 \pm 0.06$ (consistent with a cosmological constant) with the present day Hubble constant as $H_{0}=70.0 \pm 0.6$ ${\rm km} \, {\rm s}^{-1} {\rm Mpc}^{-1}$ and density parameter as $Ω_{Λ0}=0.723 \pm 0.025$, while non-parametric $w(z)$ solutions give us a probability map which is centred at $H_{0}=70.04 \pm 1$ ${\rm km} \, {\rm s}^{-1} {\rm Mpc}^{-1}$ and $Ω_{Λ0}=0.724 \pm 0.03$. Our chosen GRB data sample with full correlation matrix allows us to estimate the amount, as well as quality (errors) of data, needed to constrain $w(z)$ in the redshift range extending an order of magnitude in beyond the farthest SNeIa measured.

description: Westervelt's equation is a nonlinear wave equation that is widely used to model the propagation of sound waves in a compressible medium, with one important application being ultra-sound in human tissue. Two fundamental aspects of this equation -- symmetries and conservation laws -- are studied in the present work by modern methods. Numerous results are obtained: new conserved integrals; potential systems yielding hidden symmetries and nonlocal conservation laws; mapping of Westervelt's equation in the undamped case into a linear wave equation; exact solutions arising from the mapping; hidden variational structures, including a Lagrangian and a Hamiltonian; a recursion operator and a Noether operator; contact symmetries; higher-order symmetries and conservation laws.

description: We investigate the Brownian motion of boomerang colloidal particles confined between two glass plates. Our experimental observations show that the mean displacements are biased towards the center of hydrodynamic stress (CoH), and that the mean-square displacements exhibit a crossover from short time faster to long time slower diffusion with the short-time diffusion coefficients dependent on the points used for tracking. A model based on Langevin theory elucidates that these behaviors are ascribed to a superposition of two diffusive modes: the ellipsoidal motion of the CoH and the rotational motion of the tracking point with respect to the CoH.

Year: 2018

description: This paper aims to review the changes over time in the field of organization of resources to determine if the movement and progress of knowledge organization are based on/ or influenced by scientific and philosophical paradigms. These changes have been analyzed from the paradigmatic perspective toward the organization of information and knowledge organization.\nThe method of this research is a historical overview. The review has been carried out in various texts based on Thomas Cohen’s theory.\nFindings show that knowledge organization movement is based on developing philosophical approaches. Also advancements in information technology have been affected by forming ontological vision of knowledge organization.\nResults show that knowledge organization has a paradigmatic movement. Paradigms based on philosophical approaches such as pragmatism and experientialism have greatly influenced the knowledge organization. These changes in philosophical approaches, along with the changes in the technologies used in organizing knowledge, have created paradigms in the organization of resources. The tendency to organize knowledge in the twenty-first century is the result of changing the paradigm in this area.

description: Today, data, information and knowledge are very important assets for organizations and the effective management of knowledge is considered a way to gain and sustain a competitive advantage in a highly dynamic environment of the organizations. With the growth of information and communication technologies, cloud computing and Web 2.0, as new phenomena, recommend helpful solutions in the field of knowledge management. In this article, we introduce and review various models of the cloud-based knowledge management systems at first, and then we present a framework for knowledge management system in the cloud-computing environment. The proposed framework consists of seven main components. To compare to the other reviewed models, in this framework, additionally, we used the numerous benefits of cloud computing such as reducing the cost of hardware and software, flexibility, accessibility at any time and place, collaboration, etc. where we tried to concerning the great capability of cloud computing for gathering knowledge and providing business intelligence infrastructure.

description: Environmental policy makers use life cycle assessment (LCA) to reduce scientific uncertainties about the environmental impact of technologies and products. However, the structure of the U.S. policy-making system often acts as a roadblock to the use of LCA outputs in decision making. This chapter discusses specific characteristics of the U.S. political system, which often make uncertainty-reducing assessments like life cycle assessment fall in a decision-making context: the incremental nature of the U.S. policy-making system; the place-based nature of environmental politics in the United States; and the uncertainties associated with the most environmental and scientific challenges.
Presenting a Framework for Explaining the Competencies of Chief Knowledge Officer through Meta-Synthesis Method
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2018

description: This paper provides a framework to clarify the competencies of the Chief Knowledge Officer in organizations. For this purpose, meta-synthesis methodology was adopted. From 161 sources founded in meta-synthesis process, 15 articles were consistent with accepted standards. As a result of combining the findings, 60 codes and five main concepts (specialization in knowledge management, mastery of business knowledge, interpersonal skills, managerial skills and personal characteristics) and two themes (technical and social) were identified. Shannon Entropy Analysis showed that managerial competencies and awareness about technologies of knowledge management are the most important factors. Organizations can benefit from the results of this study to recruit a chief knowledge officer. No article was found by the researchers having research integrity and methodology. Therefore, this paper has innovation.
Design of laser-coupled honeycomb optical lattices supporting Chern insulators

description: We introduce an explicit scheme to realize Chern insulating phases employing cold atoms trapped in a state-dependent optical lattice and laser-induced tunneling processes. The scheme uses two internal states, a ground state and a long-lived excited state, respectively trapped in separate triangular and honeycomb optical lattices. A resonant laser coherently coupling the two internal states enables hopping between the two sublattices with a Peierls-like phase factor. Although laser-induced hopping by itself does not lead to topological bands with non-zero Chern numbers, we find that such bands emerge when adding an auxiliary lattice that perturbs the lattice structure, effectively turning it at low energies into a realization of the Haldane model: A two-dimensional honeycomb lattice breaking time-reversal symmetry. We investigate the parameters of the resulting tight-binding model using first-principles band structure calculations to estimate the relevant regimes for experimental implementation.

description: These Sessional Clippings books cover the period 1891 to 1972, and include newspaper accounts written by various legislative reporters who covered debates occurring in the British Columbia Legislative Assembly. Transcripts of debates of the Legislative Assembly (Hansard) were not published in B.C. until 1970; hence these "Sessional Clipping Books" augment the "Journals", the record of daily proceedings of the Legislative Assembly. Selected clippings from various newspapers including the Vancouver Sun, the Vancouver Province, the Colonist, and the Times newspapers, relating to the newspaper reports concerning activities of the Legislature. The original sessional clippings books comprise 351 ledger size print volumes, held at the Legislative Library in Victoria BC. The print volumes were microfilmed onto 26 reels in 1977 under a Tri University Libraries (TRIUL) project by Precision Micrographic Services (Vancouver, B.C.), with the permission of the Legislative Library, Victoria, British Columbia. This digital collection was created by scanning the 26 microfilm reels.

description: Proteins are complex molecules that play many roles in living organisms. Understanding how proteins are structured, how they move, and how they interact with other molecules is crucial for drug design. In this work, Stefan used the technique of NMR to study the structure, motion, and interactions of two proteins that are crucial for the pathogenic bacteria B. pseudomallei and N. meningitidis. This work measured the dynamic behavior of these two proteins, providing crucial insights into their function, and identified small molecules that interact with them, providing much-needed starting points for the development of new drugs against these bacteria.

description: The unusual severity and return time of the 2005 and 2010 dry-season droughts in western Amazon is attributed partly to decadal climate fluctuations and a modest drying trend. Decadal variability of western Amazon hydroclimate is highly correlated to the Atlantic sea surface temperature (SST) north-south gradient (NSG). Shifts of dry and wet events frequencies are also related to the NSG phase, with a 66% chance of 3+ years of dry events per decade when NSG > 0 and 19% when NSG

description: 1. Gruberia calkinsi Beltrán, 1933 (Fig. 1A, B)
Diagnosis. Live cell 440­1,000 μm in length; anterior slightly curved, contractile, posterior narrowed in shape; peristome about 1/2­2/3 of cell in length; 36­45 somatic kineties; 273­441 adoral membranelles; macronuclei, moniliform, 9­15 in number.
Material examined. On October 24, 2014, at Seonnyeobawi Beach, the Yellow Sea, Korea (37°26′N, 126°22′E). Voucher slides. A slide of protargol­impregnated specimens was deposited at the National Institute of Biological Resources, Korea (NIBRPR0000106616).
Remarks. In this study, the genus Gruberia is firstly reported from Korea. Gruberia calkinsi is similar to G. beninensis Dragesco and Dragesco­Kernéis, 1986 with respect to cell size and form of macronucleus (Al­Rasheid, 2001). However, G. calkinsi can be distinguished from the G. beninensis population redescribed by Al­Rasheid (2001) in the number of adoral membranelles (273­441 vs. 130­170).

description: The scaling between X-ray observables and mass for galaxy clusters and groups is instrumental for cluster based cosmology and an important probe for the thermodynamics of the intracluster gas. We calibrate a scaling relation between the weak lensing mass and X-ray spectroscopic temperature for 10 galaxy groups in the COSMOS field, combined with 55 higher mass clusters from the literature. The COSMOS data includes HST imaging and redshift measurements of 46 source galaxies per square arcmin, enabling us to perform unique weak lensing measurements of low mass systems. Our sample extends the mass range of the lensing calibrated M-T relation an order of magnitude lower than any previous study, resulting in a power-law slope of 1.48$^{+0.13}_{-0.09}$. The slope is consistent with the self-similar model, predictions from simulations, and observations of clusters. However, X-ray observations relying on mass measurements derived under the assumption of hydrostatic equilibrium have indicated that masses at group scales are lower than expected. Both simulations and observations suggest that hydrostatic mass measurements can be biased low. Our external weak lensing masses provides the first observational support for hydrostatic mass bias at group level, showing an increasing bias with decreasing temperature and reaching a level of 30-50% at 1 keV.

We further show that the effect of viscosity is also formulated in the form of the variational method including fluctuations.

Subjects: subject: Systems and Control (eess.SY)

description: The problem of robustly, asymptotically stabilizing a point (or a set) with two output-feedback hybrid controllers is considered. These control laws may have different objectives, e.g., the closed-loop systems resulting with each controller may have different attractors. We provide a control algorithm that combines the two hybrid controllers to accomplish the stabilization task. The algorithm consists of a hybrid supervisor that, based on the values of plant's outputs and (norm) state estimates, selects the hybrid controller that should be applied to the plant. The accomplishment of the stabilization task relies on an output-to-state stability property induced by the controllers, which enables the construction of an estimator for the norm of the plant's state. The algorithm is motivated by and applied to robust, semi-global stabilization problems uniting two controllers.

description: Το φουμαρικό οξύ αποτελεί ένα από τα οργανικά οξέα που βρίσκονται στους οίνους και συναντάται στις ράγες των σταφυλιών. Από το 2021 η χρήση του επιτράπηκε από τον διατροφικό κώδικα «Codex Alimentarius» και τον «Διεθνή Οργανισμό Αμπέλου και Οίνου» (OIV) για την αναστολή της μηλογαλακτικής ζύμωσης. Στην παρούσα πτυχιακή εργασία προκειμένου να μελετηθεί η επίδραση του φουμαρικού οξέος στη μηλογαλακτική ζύμωση και στα βασικά χαρακτηριστικά ροζέ οίνου, υλοποιήθηκε ένα παραγοντικό πείραμα 3x3x2, δηλαδή με τρία επίπεδα προσθήκης φουμαρικού οξέος (0, 300 και 600 mg/L), τρία επίπεδα προσθήκης μηλικού οξέος (0, 1 και 3 g/L) και προσθήκη ή μη γαλακτικών βακτηρίων του είδους Oenococcus oeni. Οι αναλύσεις των δειγμάτων διενεργήθηκαν σε διάστημα 3 και 6 μηνών και σύμφωνα με τα αποτελέσματα φαίνεται πως δεν έλαβε χώρα η μηλογαλακτική ζύμωση τόσο στα δείγματα στα οποία έγινε προσθήκη φουμαρικού, όσο και στα τυφλά δείγματα. Σημαντικές αλλαγές ωστόσο, παρατηρήθηκαν στη σύσταση του οίνου όσον αφορά το pH, την οξύτητα και το χρώμα του. Συγκεκριμένα στο διάστημα των 0 μηνών, φαίνεται οι προσθήκες 300 και 600 mg/L φουμαρικού οξέος να μείωσαν το pH κατά 0,05 και 0,11 αντίστοιχα, ενώ οι προσθήκες 1 και 3 g/L μηλικού οξέος κατά 0,20 και 0,33. Αντίστοιχα, σημειώθηκε αύξηση 0,30 και 0,75 g/L στην ογκομετρούμενη οξύτητα κατά την προσθήκη 300 και 600 mg/L φουμαρικού οξέος και 1,87 και 3,30 g/L κατά την προσθήκη 1 και 3 g/L μηλικού οξέος. Επομένως ισχυρότερο οξύ αποδείχθηκε το φουμαρικό. Η μείωση αυτή του pH παράλληλα, προκάλεσε αύξηση του χρώματος των δειγμάτων και μείωση της διαύγειάς τους. Ενδεικτικά η τιμή της χρωματικής έντασης για το δείγμα χωρίς καμία προσθήκη οξέος ήταν 6,18, ενώ η αντίστοιχη τιμή για το δείγμα με συγκέντρωση φουμαρικού 600 mg/L και μηλικού 3 g/L ήταν 7,78 στους 3 μήνες. Μείωση ωστόσο της χρωματικής έντασης και της διαύγειας σημειώθηκε μεταξύ του διαστήματος των 3 και 6 μηνών, με σχετική αύξηση της χρωματικής απόχρωση.

description: We perform a detailed analysis on broad pulses in bright Gamma-ray bursts (GRBs) to understand the evolution of GRB broad pulses. Using the temporal and spectral properties, we test the high latitude emission (HLE) scenario in the decaying phase of broad pulses. The HLE originates from the curvature effect of a relativistic spherical jet, where higher latitude photons are delayed and softer than the observer's line-of-sight emission. The signature of HLE has not yet been identified undisputedly during the prompt emission of GRBs. The HLE theory predicts a specific relation, F$_{ν, E_{p}}$ $\propto$ E$_{p}\!^{2}$, between the peak energy $E_{p}$ in $ν$F$_ν$ spectra and the spectral flux F$_ν$ measured at $E_{p}$, F$_{ν, E_{p}}$. We search for evidence of this relation in 2157 GRBs detected by the Gamma-ray Burst Monitor (GBM) on board the Fermi Gamma-ray Space Telescope (Fermi) from the years 2008 to 2017. After imposing unbiased selection criteria in order to minimize contamination in a signal by background and overlaps of pulses, we build a sample of 32 broad pulses in 32 GRBs. We perform a time-resolved spectral analysis on each of these 32 broad pulses and find that the evolution of 18 pulses (56%) is clearly consistent with the HLE relation. For the 18 broad pulses, the exponent $δ$ in the relation of F$_{ν, E_{p}}$ $\propto$ E$_{p}\!^δ$ is distributed as a Gaussian function with median and width of 1.99 and 0.34, respectively. This result provides constraint on the emission radius of GRBs with the HLE signature.

description: Ο τεχνολογικός εκσυγχρονισμός της βιομηχανικής παραγωγής δημιουργεί όλο και πιο πολύπλοκες, δυναμικές και ενίοτε χαοτικές συνθήκες στη σύγχρονη καθημερινότητα. Ένα από τα μεγαλύτερα ζητήματα που καλείται να επιλύσει ο τομέας της βιομηχανικής παραγωγής είναι να παρέχει προϊόντα και υπηρεσίες υψηλής ποιότητας, για το σκοπό αυτό κρίνεται απαραίτητο να χρησιμοποιηθούν όλα τα διαθέσιμα τεχνολογικά μέσα, όπως η μηχανική μάθηση. Όσο πιο σύγχρονη καινοτομία στον τομέα της παραγωγής, η μηχανική μάθηση θεωρείται η λύση σε πολλά ζητήματα σχετικά με την σύγχρονη βιομηχανία. Το συγκεκριμένο θέμα είχε απασχολήσει ιδιαίτερα πολλούς επιστήμονες και συνεχίζει να μονοπωλεί το ερευνητικό ενδιαφέρον αμείωτα. Ωστόσο, ως επιστημονικό πεδίο και ερευνητικό αντικείμενο είναι πολύ ευρεία, γεγονός που προκαλεί μεγάλη σύγχυση και προβληματισμό ενω ταυτόχρονα συνιστα Ωστόσο, ο τομέας του machine learning είναι πολύ ευρύς και ακόμη και συγκεχυμένος, γεγονός που αποτελεί πρόκληση και εμπόδιο στην ευρεία εφαρμογή του. Η παρούσα εργασία επιχειρεί να παρουσιάσει τις διαθέσιμες τεχνικές μηχανικής μάθησης και να αναδείξει βασικές πτυχές αυτού του μάλλον περίπλοκου τομέα. Ιδιαίτερη έμφαση δίνεται στα δυνητικά οφέλη από την αξιοποίηση της μηχανικής μάθησης, καθώς και σε παραδείγματα επιτυχημένων εφαρμογών στην βιομηχανία.

description: Το πλαστικό είναι ένα υλικό που έχει ενσωματωθεί σε κάθε πτυχή της ζωής των ανθρώπων και έχει γίνει αναπόσπαστο μέρος της καθημερινότητάς μας. Αυτό οφείλεται στην πολυμορφία των ιδιοτήτων του πλαστικού, που το καθιστούν κατάλληλο για πολλές εφαρμογές. Ωστόσο, η ευρεία χρήση του πλαστικού έχει οδηγήσει σε προβλήματα περιβαλλοντικής φύσης, κυρίως λόγω της ανθεκτικότητάς του στη διάσπαση. Τα πλαστικά απορρίμματα μπορούν να προκαλέσουν ρύπανση του περιβάλλοντος, ιδίως στους ωκεανούς, και να απειλήσουν την υγεία των ανθρώπων και τη βιοποικιλότητα. Η ενσωμάτωση της Βιώσιμης και Πράσινης Ανάπτυξης στις βιομηχανίες πλαστικών είναι ένα σημαντικό βήμα προς τη μείωση των περιβαλλοντικών επιπτώσεων τους. Οι εταιρείες "Πλαστικά Κρήτης ΑΒΕΕ" και "Πλαστικά Θράκης ΑΒΕΕ" έχουν αναλάβει δράσεις για την εφαρμογή καινοτόμων τεχνολογιών και τεχνικών που υποστηρίζουν τη βιώσιμη παραγωγή. Μερικές από αυτές τις δράσεις είναι η χρήση των βιώσιμων υλικών, η κυκλική οικονομία και καινοτόμες τεχνολογίες. Εν συνεχεία, η Πράσινη και Βιώσιμη Ανάπτυξη απαιτεί τη συμμετοχή και την κατανόηση όλων των ενδιαφερομένων μερών, από τους καταναλωτές μέχρι τις βιομηχανίες, την κυβέρνηση, και την επιστημονική κοινότητα Συνοψίζοντας, η αντίληψη και η συνεργασία είναι βασικοί συντελεστές για τη δημιουργία μιας βιώσιμης και πράσινης κοινωνίας που μπορεί να είναι αντάξια στις μελλοντικές περιβαλλοντικές προκλήσεις.

description: We propose a method that leverages graph neural networks, multi-level message passing, and unsupervised training to enable real-time prediction of realistic clothing dynamics. Whereas existing methods based on linear blend skinning must be trained for specific garments, our method is agnostic to body shape and applies to tight-fitting garments as well as loose, free-flowing clothing. Our method furthermore handles changes in topology (e.g., garments with buttons or zippers) and material properties at inference time. As one key contribution, we propose a hierarchical message-passing scheme that efficiently propagates stiff stretching modes while preserving local detail. We empirically show that our method outperforms strong baselines quantitatively and that its results are perceived as more realistic than state-of-the-art methods.
Where Do Galaxies End?

description: Our current view of galaxies considers them as systems of stars and gas embedded in extended halos of dark matter, much of it formed by the infall of smaller systems at earlier times. The true extent of a galaxy remains poorly determined, with the virial radius (R_vir) providing a characteristic separation between collapsed structures in dynamical equilibrium and external infalling matter. Other physical estimates of the extent of gravitational influence include the gravitational radius, gas accretion radius, and "galactopause" arising from outflows that stall at 100-200 kpc over a range of outflow parameters and confining gas pressures. Physical criteria are proposed to define bound structures, including a more realistic definition of R_vir (M*, M_h, z_a) for stellar mass M* and halo mass M_h, half of which formed at "assembly redshifts" z_a = 0.7-1.3. We estimate the extent of bound gas and dark matter around L* galaxies to be ~200 kpc. The new virial radii, with mean R_vir ~ 200 kpc, are 40-50% smaller than values estimated in recent HST/COS detections of H I and O VI absorbers around galaxies. In the new formalism, the Milky Way stellar mass, log M* = 10.7 +/- 0.1, would correspond to R_vir = 153 (+25,-16) kpc for half-mass halo assembly at z_a = 1.06 +/- 0.03. The frequency per unit redshift of low-redshift O VI absorption lines in QSO spectra suggests absorber sizes ~150 kpc when related to intervening 0.1L* galaxies. This formalism is intended to clarify semantic differences arising from observations of extended gas in galactic halos, circumgalactic medium (CGM), and filaments of the intergalactic medium (IGM). Astronomers should refer to bound gas in the galactic halo or CGM, and unbound gas at the CGM-IGM interface, on its way into the IGM.

description: We experimentally study the performance of a programmable quantum annealing processor, the D-Wave One (DW1) with up to 108 qubits, on maximum satisfiability problem with 2 variables per clause (MAX 2-SAT) problems. We consider ensembles of random problems characterized by a fixed clause density, an order parameter which we tune through its critical value in our experiments. We demonstrate that the DW1 is sensitive to the critical value of the clause density. The DW1 results are verified and compared with akmaxsat, an exact, state-of-the-art algorithm. We study the relative performance of the two solvers and how they correlate in terms of problem hardness. We find that the DW1 performance scales more favorably with problem size and that problem hardness correlation is essentially non-existent. We discuss the relevance and limitations of such a comparison.

description: One of the main challenges of knowledge management in today’s knowledge-based economy is encouraging people to share their knowledge. Knowledge-based structures due to the pressing need for participation and trust-based approach should be pursued, because creating and sharing knowledge requires a high level of confidence and optimism in the relations between members of the organization together. It is considered especially in information and communication technology-based organizations, because they are largely composed of groups that their ultimate goal is the successful implementation of information systems projects. This study aimed to investigate the relationship of trust and dependence among individuals in the successful sharing of information across the organization. A survey implemented to examines the opinions of experts and managers of Information and Communication Technology Organization of Shiraz Municipality. After data collection and preparation, conceptual research model analyzed by structural equation modeling. The results show that communication between members has positive and significant impact on the trust of information systems group. Also, it has found that the effect of knowledge sharing among members is meaningful on increasing performance of the department of information systems.

Finite f-Electron Bandwidth in a Heavy Fermion Model

description: Determinant Quantum Monte Carlo (DQMC) is used to study the effect of non-zero hopping t_f in the localized f-band of the periodic Anderson model (PAM) in two dimensions. The low temperature properties are determined in the plane of interband hybridization V and t_f at fixed U_f and half-filling, including the case when the sign of t_f is opposite to that of the conduction band t_d. For t_f and t_d of the same sign, and when t_f=t_d > (V =4_td)^2, the non-interacting system is metallic. We show that a remnant of the band insulator to metal line at U_f = 0 persists in the interacting system, manifesting itself as a maximal tendency toward antiferromagnetic correlations at low temperature. In this optimal t_f region, short range (e.g. near-neighbor) and long-range spin correlations develop at similar temperatures and have comparable magnitude. Both observations are in stark contrast with the situation in the widely studied PAM (t_f = 0) and single band Hubbard model, where short range correlations are stronger and develop at higher temperature. The effect that finite t_f has on Kondo screening is investigated by considering the evolution of the local density of states for selected t_f as a function of V . We use mean field theory as a tool to discriminate those aspects of the physics that are genuinely many-body in character.

description: Στην παρούσα εργασία αναπτύχθηκε η αναδυόμενη μέθοδος χημικής ανακύκλωσης των πλαστικών αποβλήτων και παρουσίαζονται στοιχεία που αφορούν την περιβαλλοντική, οικονομική και τεχνολογική απόδοση της. Αρχικά γίνεται αναφορά του προβληματος των πλαστικών παραθέτοντας στοιχέια για τις ποσότητες παραγωγής και διαχείρισης αυτών. Έπειτα αναλύονται οι στόχοι που έχει θέσει η ΕΕ και η Ελλάδα για την πάταξη του προβλήματος των πλαστικών και η πρόοδος αυτών. Τέλος αναφέρεται η τεχνολογική ωριμότητα των τεχνολογιών χημικής ανακύκλωσης καθώς και η περιβαλλοντική και οικονομική τους απόδοση. Από την ανάλυση των παραπάνω τα κύρια συμπεράσματα είναι ότι η παραγωγή των πλαστικών προϊόντων και κατα συνέπεια των αποβλήτων θα συνεχίσει να αυξάνεται παγκοσμίως. Υλικά του τομέα της συσκευασίας όπως PE, PP κ.α. (πολυολεφίνες) είναι τα πιο δημοφιλή και απαρτίζουν το μεγαλύτερο ποσοστό και παραγωγής και αποβλήτων. Οι στόχοι που έχει θέσει η ΕΕ δεν είναι εύκολο να επιτευχθούν απο όλες τις χώρες κράτη μέλη πόσο μάλιστα με την αλλαγή της νομοθεσίας για την μέτρηση του ανακυκλωμένου περιεχομένου. Τεχνολογίες όπως η θερμική πυρόλυση είναι η πιο εμπορική παγκοσμίως παράγοντας ήδη προϊόντα με χημικά ανακυκλωμένο περιέχομενο. Τα περιβαλλοντικά και οικονομικά στοιχεία περί χημικής ανακύκλωσης είναι ενδεικτικά και χρειάζεται περισσότερη έρευνα και διαφάνεια απο τους οργανισμούς και τις εταιρείες. Παρόλα αυτά η χημική ανακύκλωση προβλέπουν οτι θα αποτελέσει πυλώνα στήριξης στο τομέα διαχείρισης των πλαστικών στο μέλλον συμπληρώνοντας την ήδη υπάρχουσα μηχανική. Στην ΕΕ για να συμβεί αυτό πρέπει να θεσμοθετηθούν επιπλέον θέματα και διευκρυνίσεις που αφορούν την χημική ανακύκλωση ώστε να επιταχυνθεί η ένταξη της. Τέλος η σκοπιμότητα κατασκευής μιας μονάδας χημικής ανακύκλωσης στον Ελλαδικό χώρο αμφισβητείται προς το παρόν λόγω έλλειψης σημαντικών στοιχείων που θα δώσουν το πράσινο φώς για την επένδυση.
