Cities, Disaster Risk and Adaptation

Worldwide, disasters and climate change pose a serious risk to sustainable urban development, resulting in escalating human and economic costs. Consequently, city authorities and other urban actors face the challenge of integrating risk reduction and adaptation strategies into their work, although related knowledge and expertise are still scarce. Cities, Disaster Risk and Adaptation explores ways

On the Free Distance of LDPC Convolutional Codes

A lower bound on the free distance of LDPC convolutional codes defined by syndrome former matrices comprised of MtimesM permutation matrices is derived. We show that asymptotically, i.e., as Mrarrinfin, for almost all codes in the ensemble the free distance grows linearly with constraint length

Mänskliga rättigheter och religion

Under senare år har religion kommit att återigen spela en framträdande roll i svensk och internationell kontext. Mer eller mindre dagligen konfronteras vi med frågor som relaterar till religion och mänskliga rättigheter. Detta ställer högre krav på kunskaper om och förhållningssätt till det som sker runt omkring oss. I den här antologin skriver svenska forskare om religion och mänskliga rättighet

Vanadium Oxide on TiO2(B) - a HREM Study of Catalysis by Support Interaction

A model catalyst system with a loading range between 1/4 to 10 theoretical layers of vanadium oxide on TiO2(B ) support was tried for selective ammoxidation and oxidation of toluene. In the case of ammoxidation, a peak in conversion rate per unit surface area was found for a catalyst with a coverage of about 2 theoretical layers, indicating a strong interaction between the catalyst and the otherwi

ERP System Procurement in SMEs – Two contrasting ways

Enterprise resource planning (ERP) systems have originally been developed for large enterprises (LEs). However, market saturation, integration of supply chains and technology improvements have led to small and medium-sized enterprises (SMEs) have started adopting ERP systems. Though there is a focus shift from LEs to SMEs in the ERP market, most academic literature on ERP systems is based on findi

OMAC: An Opportunistic Medium Access Control Protocol for IEEE 802.11 Wireless Networks

The ambitious goal of the upcoming IEEE 802.11ax (HEW) standard for wireless LANs (WLANs) to enhance throughput by four times (and beyond), compared with IEEE 802.11ac, demands a radical improvement of present medium access control (MAC) functionality. To this end, a promising paradigm would be a graceful migration towards new MAC protocols which incorporate higher certainty in their decisions. Ho

Functional analysis of the mouse J chain

We have in this study analyzed the function of the murine Joining chain (J chain) in vivo. J chain is a polypeptide found in sera and secretions in complex with pentameric IgM and dimeric IgA. J chain is expressed in terminally differentiated B lymphocytes and needed for the transport of dimeric IgA and pentameric IgM over mucosal surfaces via the poly Ig receptor. A mouse deficient for J chain wa
