Kisel är ett vanligt förekommande grundämne som gärna bildar en oxid, nämligen kiseldioxid. Kiseldioxid träffar man i hög utsträckning på i det dagliga livet. Det är nämligen huvudbeståndsdelen i sand, glasvaror, kvarts, många keramiska material men också i den färgskiftande ädelstenen opal. Det finns också flera grupper av porösa kiseldioxidmaterial, till exempel så kallade zeoliter som har myckeThe formation process of porous silica materials is an intricate process, involving a number of components that interact to form a highly organized material. Both zeolites and mesoporous silica materials typically require the presence of organic structure director agents (SDAs) around which the silica network polymerizes. For zeolites the SDAs are molecular and for mesoporous silica the SDAs assem

I denna rapport analyseras effekterna av sänkta parkeringsnormer för bostäder för invånarna i det centrumnära, och relativt nybyggda, bostadsområdet Porslinsfabriken i Göteborg. Porslinsfabriken är med en relativt låg parkeringsnorm på 0,57 platser per lägenhet ett bra exempel på en parkeringspolitik som förs i alltfler kommuner. Resultatet visar att 19 procent av hushållen har minskat bilinnehaveThis report analyses the effects of lowered parking requirements for residents in the centrally located, relatively newly built housing area, Porslinsfabriken in Gothenburg. Porslinsfabriken has a relatively low parking requirement of 0.57 places per apartment and is a good example of a parking policy being introduced in many Swedish municipalities. The results show that 19 percent of households h

Landskapets geologi, former och andra naturgivna egenskaper har en förhållandevis undanskymd roll i dagens infrastrukturplanering jämfört med den vikt som läggs vid biologiska och ekologiska företeelser och egenskaper. Många gånger är det dessutom endast extremföreteelser som lyfts fram i samband med infrastrukturplaneringen medan det så kallade vardagslandskapet får träda tillbaka, trots att det

Short presentation of medieval archaeology at the crossroad of different methodological perspectives.

Aim: Hearing loss (as reflected by abnormal sound detection) is a frequently reported consequence of Type 1 diabetes mellitus. We sought to evaluate sound detection, auditory neural function and binaural processing ability in a group of school-aged participants with Type 1 diabetes and to assess their functional hearing and general communication ability. Methods: A range of electroacoustic, electr

Background: Older people with cognitive impairment represent a large group of patients in acute care settings. Research show that these acute care environments can be unsafe and even unfriendly for frail older patients. Research and clinical experience show that being a nurse in acute/specialised medical facilities means to work in a high-speed, technologically complex and demanding environment. W

Many popular first order algorithms for convex optimization, such as forward-backward splitting, Douglas-Rachford splitting, and the alternating direction method of multipliers (ADMM), can be formulated as averaged iteration of a nonexpansive mapping. In this paper we propose a line search for averaged iteration that preserves the theoretical convergence guarantee, while often accelerating practic

Purpose: This study explores informational structures producing and organizing the construction of waste sorting in Sweden. It shows how the issue is constructed by it being searched for in Google and how this contributes to the specific informational texture of waste sorting in Sweden. It is guided by the following questions: Who are the main actors and which are the central topics featuring in G

Background. CD14, a coreceptor for several pattern recognition receptors and a widely used monocyte/macrophage marker, plays a key role in host responses to gram-negative bacteria. Despite the central role of CD14 in the inflammatory response to lipopolysaccharide and other microbial products and in the dissemination of bacteria in some infections, the signaling networks controlled by CD14 during

With the arrival of heterogeneous manycores comprising various features to support task, data and instruction-level parallelism, developing applications that take full advantage of the hardware parallel features has become a major challenge. In this paper, we present an extension to our CAL compilation framework (CAL2Many) that supports data parallelism in the CAL Actor Language. Our compilation f

In our article entitled ‘The Responsibility to Protect – An incoherent Doctrine?’ we claimed that R2P in the version proposed by the ICISS is incoherent. We argued that the ICISS-report used the criteria of right intention, proportionality and legitimate authority to determine when a humanitarian intervention is obligatory and we continued by arguing that this cannot be done in a coherent manner.

Molecularly imprinted polymers (MIPs) are artificial receptors designed for the selective recognition of template molecules. These polymers have been applied in analytical separations, as chemical sensors and in drug delivery system due to their low cost and high stability. In recent years MIP beads, especially those with good selectivity in aqueous solution, have become attractive as they can be

This chapter explores trends in an emotional or experience economy as this relates to media management. The case of reality entertainment is used as an example of the tricky balancing act between the management and production of media content that has emotional resonance and audience engagement with such content. The research draws on quantitative and qualitative empirical audience data to illumin

Tumor-specific monoclonal antibodies (mAbs) offer several modes of tumor cell killing, from direct cytotoxic activity to indirect mechanisms employing the host immune system, particularly its innate branch. The latter effector functions seem to dominate among clinically approved anti-cancer mAbs and major efforts are being undertaken by both academia and the pharmaceutical industry with the aim to

Ett resilient hushåll, som är väl förberett för en kris, ökar krishanteringsförmågan för samhället i stort när katastrofen är ett faktum – och mildrar konsekvenserna. Trots att hushåll på landsbygden drabbades hårt av stormen Gudrun 2005 var de väsentliga för krishanteringen som helhet, inte minst för överlevnad och mellanmänsklig omsorg. Hur såg detta skeende ut, och på vilket sätt kan analys av

The electrochemically coated conducting paper based point-of-care diagnostics using amperometric sensing principles for troponin detection has been demonstrated in the present report. The cost-effective and stable conducting polymer coating was achieved on papers using screen printing followed by electrochemical deposition techniques for the first time. The cyclic voltammetric analysis has reveale
