Leaching tests have been carried out on concrete with fly ash or blast furnace slag as additives. Different models for leaching processes are proposed and analyzed, and physical/chemical interactions that may occur during a leaching process are discussed. Furthermore, simulations with different conditions and with different mathematical solutions are shown. The results of the leaching tests are di

Today there are climate policy targets within the EU and Sweden about limiting global warming and drastically reducing greenhouse gas emissions. In order to stay within the goal of a global warming of less than 2 ºC, the industrialised countries should decrease their emissions by 80-95 % in 2050, and bring them down to zero in the longer run. Scenario studies indicate that this is possible to achi

In this paper we develop an Enterprise Systems Implementation Methodology in Action framework. The framework is grounded in contemporary views on methodology in action (theoretical grounding) and enhanced by an empirical study (empirical grounding). The notion of Implementation Methodology in Action, as articulated in this paper, integrates two complementary views that conceptualise a methodology

Popular Abstract in Swedish Peptidaser, proteolytiska enzymer eller proteinhydrolaser är olika benämningar på samma sorts enzymer. Deras funktion är att bryta ner proteiner i alla celler, vävnader eller vätskor i antingen vår egen kropp eller i någon annan levande organism. Varför behövs dessa enzymer? Deras funktion påminner om den av en återvinningscentral, där peptidaserna avvecklar felfungeraProteolytic enzymes are enzymes that hydrolyze peptide bonds in peptides and proteins. This ability to carry out protein degradation is essential for many cellular and extracellular processes that occur in all living organisms. Cysteine peptidases constitute a class of proteolytic enzymes. Among these, papain-like (C1) peptidases are the mostly studied ones. Inhibitors regulate proteolytic activit

Popular Abstract in Swedish INLEDNING – Människans hörsel är beroende av att öra, nervsystem och hjärna alla fungerar som de skall. Det inkluderar mellanörat; med hörselben och trumhinna, innerörat; med sina sinnesceller, hörselnerven och hörselcentrum i hjärnan. Det är välkänt att ändrat omgivningstryck påverkar örat - vi får till exempel alla lock i öronen och hör dåligt om vi inte kan tryckutjäResults from experimental studies, as well as clinical studies, are used to elucidate the effects of ambient pressure changes on cochlear hydrodynamics and function. The perilymph pressure changes and the pressure release effects of the cochlear aqueduct (CA) and Eustachian tube (ET) in cats exposed to hypobaric pressure are elucidated. The focus is on the emergence of the pressure gradients betwe
