The utiquity and many roles of exopolymers (EPS) in aquatic systems

open access: yesScientia Marina, 2004
Exopolymers (EPS) are produced by unicellular and multicellular organisms. They consist largely of polysaccharides that hydrate rapidly on contact with water and link to form gels.

Prediction of Optimum Expanded Polystyrene Densities for Best Thermal Insulation Performances of Polystyrene Composite Particleboards by Using Artificial Neural Network

open access: yesDrvna Industrija, 2022
The objective of this study is to predict the optimum expanded polystyrene (EPS) densities for the best insulation properties of the particleboards manufactured with waste EPS instead of formaldehyde-based adhesives used in particleboard production with ...

Experimental investigation of usability of modified asphalt binder with waste expanded polystyrene (EPS)

open access: yesJournal of Innovative Transportation, 2023
EPS (Expanded polystyrene) is widely used in construction and packaging industries. Unfortunately, EPS is not mostly recyclable because it might not be economically feasible to store, transport, and process EPS so that it becomes recyclable.

The Transition to a Giant Vortex Phase in a Fast Rotating Bose-Einstein Condensate [PDF]

open access: yes, 2010
We study the Gross-Pitaevskii (GP) energy functional for a fast rotating Bose-Einstein condensate on the unit disc in two dimensions. Writing the coupling parameter as $ 1 / \eps^2 $ we consider the asymptotic regime $ \eps \to 0 $ with the angular ...

Evaluating Energy Absorption Performance of Filled Lattice Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

Korekcija određivanja položaja regulacione preklopke iz struja i napona primara i sekundara po snimljenim vrednostima pojedinačnog transformatora

open access: yesEnergija, Ekonomija, Ekologija, 2021
U radu se razmatra mogućnost direktne korekcije greške kod određivanja položaja regulacione preklopke iz napona primara i sekundara pojedinačnih transformatora koji imaju veći broj snimljenih merenih vrednosti napona i struja u manjem ili većem opsegu ...

Asymptotic behaviour of the inductance coefficient for thin conductors [PDF]

open access: yes, 2002
We study the asymptotic behaviour of the inductance coefficient for a thin toroidal inductor whose thickness depends on a small parameter $\eps>0$.

Triplet‐Triplet Annihilation Enhances Photochemical Curing Contrast for Vat‐Based 3D Printing

open access: yesAdvanced Functional Materials, EarlyView.
Triplet–triplet annihilation photopolymerization (TTAP) resins enhance curing contrast for digital light processing (DLP) 3D printing compared to conventional Type I and II photopolymerizations at matched optical densities. By exploiting a superlinear initiation response, TTAP preserves fine details, allowing reliable fabrication of complex structures ...

Isolation, selection and characterisation of microorganisms with potential to form unique consortium for wine production

open access: yesKvasný průmysl
This paper focuses on a selection of microorganisms that should eventually form a Defined Consortium of Wine Microorganisms. The consortium might serve as a sophisticated oenological product for the production of wine with attractive organoleptic ...
