  2. 1. Development of techniques to determine extracellular matrix alterations in acute and chronic lung diseases and bioengineered tissues

    Author : Iran Augusto Silva; NanoLund: Centre for Nanoscience; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Histology; semi-quantive score system; Biomaterial; ARDS; animal model;

    Abstract : Acute and chronic lung diseases are a major cause of global mortality. While pharmacological approaches exist, no therapies are curative. The only option at end-stage disease is lung transplantation which is hampered by a chronic shortage of donor organs. READ MORE

  4. 2. Uncertainty and sensitivity analysis applied to LWR neutronic and thermal-hydraulic calculations

    Author : Augusto Hernandéz Solís; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensitivity analysis; Nuclear best estimate codes; uncertainty analysis;

    Abstract : The deterministic modeling of LWRs begins with the computation of energy‐collapsed and homogenizedmacroscopic cross‐sections by means of a lattice code. Once these parameters are functionalized as a functionof the reactor state variables and discretized in space, they are used as input variables by core simulators inorder to calculate the spatial distribution of the neutron flux and thus, the spatial distribution of the power.

  5. 3. Uncertainty and Sensitivity Analysis Applied to the Validation of BWR Bundle Thermal-Hydraulic Calculations

    Author : Augusto Hernandéz Solís; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Latin Hypercube sampling; uncertainty and sensitivity analysis; Thermal‐hydraulic codes; simple random sampling; reactor safety analysis; BFBT benchmark;

    Abstract : In recent years, more realistic safety analyses of nuclear reactors have been based on best estimate (BE) computercodes. The need to validate and refine BE codes that are used in the predictions of relevant reactor safetyparameters, led to the organization of international benchmarks based on high quality experimental data.

  6. 4. Identity and Anonymity in Ad Hoc Networks

    Author : Leonardo Augusto Martucci; Simone Fischer-Hübner; Tuomas Aura; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; privacy; identity; anonymity; pseudonymity; Sybil attack; security; ad hoc; coputer networks; Datavetenskap; Computer Science;

    Abstract : In ad hoc networks every device is responsible for its own basic computer services, including packet routing, data forwarding, security, and privacy. Most of the protocols used in wired networks are not suitable for ad hoc networks, since they were designed for static environments with defined borders and highly specialized devices, such as routers, authentication servers, and firewalls.

  7. 5. Inhibition of the plasma contact system on endpoint immobilized heparin and human endothelium

    Author : Javier Augusto Sánchez Saavedra; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Contact activation system; FXII; prokallikrein; antithrombin; specific AT-binding site; immobilized heparin; heparan sulphate; endothelium;

    Abstract : When blood is exposed to foreign materials or injured tissue, several defense systems are activated. The contact with an artificial surface leads to activation of FXII, the first proenzyme of the plasma contact activation system, with concomitant triggering of the intrinsic coagulation and also the fibrinolytic-, kallikrein- and complement systems.
