Recent research on the process of biological phosphorus removal in lab-scale treatment systems has indicated that: (i) the development of an actively poly?-accumulating bacterial community after the introduction of an anaerobic period may take at least 4 months; (ii) up to 80% of all aerobic bacteria isolated from these communities are able to accumulate polyP; (iii) polyP synthesized by the bacte
Most of the genes encoding the enzymes involved in polyP synthesis and degradation and in phosphate transport have been studied in various Gram-negative bacteria. Progress has also been made in studying the biochemicalmechanisms underlying the process of enhanced biological phosphorus removal (EBPR), in particular in lab-scale systems fed with acetate or acetate plus glucose as the sole carbon and
In the light of the environmental challenges society is facing it is important thatboth products and their packaging systems are optimised from an environmental perspective. Previous research highlights that environmental optimisation of packaging requires an integrated assessment of product and packaging together.Theory on green packaging development (GPD) is comprehensive and there areexamples o
Although a diverse range of aquatic vertebrates are documented from the Upper Cretaceous (mid-Campanian) marine strata of the Kristianstad Basin in southern Sweden, only chondrichthyans and marine amniotes have been described in detail to date. In contrast, coeval actinopterygians are virtually unreported, yet their remains are extremely abundant at most sampled localities. A comprehensive assessm
During the course of this three-year project, we have studied aeolian deposits at 70 sites within sixteen areas in south-central Sweden. Inland dunes have been the focus, but some sites with coversand and coastal dunes have also been investigated. We have mapped dune morphology, mainly by LiDAR-based remote sensing, studied the internal sediment architecture by ground-penetrating radar profiling a
Mesozoic dinosaur fossils are exceptionally rare in Scandinavia. The Swedish record is typically depauperate, with the Kristianstad Basin of SkÅne (Scania) yielding all of the known fossils from Swedish Cretaceous strata. Although highly fragmentary, these body remnants are important because they provide evidence of a relatively diverse fauna, including previously recognized hesperornithiform bird
The paper gives a general discussion on methods and theories used for strength analyses of wood and wood-based products. The main aim is to discuss in general terms the benefits gained from using design approaches based on rational and scientifically sound theories. The paper presents mainly fracture mechanics theory but also other advanced modelling techniques and examples from using advanced mea
Low latency signal processing and high throughput implementations are required in order to realize real-time TDD massive MIMO communications, especially in high mobility scenarios. One of the main challenges is that the up-link and down-link turnaround time has to be within the coherence time of the wireless channel to enable efficient use of reciprocity. This paper presents a hardware architectur
In order to distinguish various film-worlds among themselves and from our intersubjective, shared reality I propose to introduce two parameters: warpedness and enfoldednes. The various ratios between these two parameters serve to create what I call »the film-world map«. The time-imageʼs embeddedness within the temporal dimension is what I mean by strong enfoldedness. A world that is enfolded is a
PurposeThe purpose of this study is to increase the understanding of multiple stakeholders’ needs, benefits and challenges, with a focus on information sharing, to improve efficiency and safety in the transportation of dangerous goods by road, rail, and sea.Design/methodology/approachInspired by grounded theory, this study is based on 21 semi-structured interviews with stakeholders representing au
Abstract Background: Surgical site infection (SSI) in the groin after vascular surgery is common and deep perivascular infection leads to long periods of hospitalization, sometimes to amputation and/or death. Negative pressure wound therapy (NPWT) is increasingly used for treating wounds such as deep perivascular groin infections after vascular surgery, but there is no scientific evidence supporti
This paper discusses the urban writing on Athenian walls as an imaginative medium of intercommunication occurring during the socioeconomic and political crisis era in Greece, over the last seven years. The street art activity on the city’s walls as a linguistic and imagery phenomenon could be approached as the main symbolic mode of public expression generated by the crisis. To investigate it field
Observationally, the galactic chemical evolution of sulphur shows a complex pattern. Some studies find no correlation between [S/Fe] and [Fe/H] at halo metallcities, which is typical for alpha -elements, others find [S/Fe] increasing towards lower metallicities, and still others find a combination of the two. Each scenario has different implications for the Galactic chemical evolution of sulphur.
PURPOSE:Gastrointestinal stromal tumor (GIST) is the most common human sarcoma and a model of targeted molecular therapy. GIST depends on oncogenic KIT signaling and responds to the tyrosine kinase inhibitor imatinib. However, imatinib is rarely curative. We hypothesized that PLX3397, which inhibits KIT and colony-stimulating-factor-1 receptor (CSF1R), would be more efficacious than imatinib in GI

To achieve a viable end-to-end security solution in a supply chain, with complex network of dependencies, a holistic perspective is required.

We provide a framework for 6 DOF pose estimation in seam-tracking applications using particle filtering. The particle filter algorithm developed incorporates measurements from both a 2 DOF laser seam tracker and the robot forward kinematics under an assumed external force. Special attention is paid to modeling of disturbances in the respective measurements, and methods are developed to assist the
