To study the active sites of dinuclear metallohydrolases new metal complexes that model these sites both in structure and function have been synthesized using two new phenol based dinucleating ligands, 2-(N-isopropyl-N-((2-pyridyl)methyl)aminomethyl)-6-(N-(carboxylmethyl)-N-((2-pyridyl)methyl)aminomethyl)-4-methylphenol (IPCPMP) and 2,6-Bis[N-(N-(carboxymethyl)-N-(pyridylmethyl)amine)methyl]-4-met

This paper reports the development of a Matlab toolbox for computational analysis of piecewise linear systems. The analysis is based on piecewise quadratic Lyapunov functions, which are computed via convex optimization. In this way, exponential stability and system performance can be assessed. The toolbox also supports efficient simulation of systems with discontinuous dynamics and sliding modes.

Ta några ingenjörsstudenter, släng in ett par kognitionsvetarstudenter och ge dem ett problem att lösa. Ut kommer interaktiva dataspel för skolan och robotar som kan imitera människors rörelser. – Vi kombinerar doing och thinking, säger Agneta Gulz, professor i kognitionsvetenskap.

Popular Abstract in Swedish Vatten är inte bara en oumbärlig resurs varav allt liv är beroende. Det är också en grundläggande ekonomisk resurs för samhällsutvecklingen. Av allt vatten på jorden är bara 0,34% tillgängligt för människan. Övriga vattenresurser föreligger som saltvatten, is eller djupt liggande grundvatten. Vattenkrisen på jorden är stor och över 780 miljoner människor saknar rimlig tFresh water scarcity, pollution and an uneven distribution have caused an increasingly serious global water crisis. One of the most widely adopted response strategies is the exploitation and use of non-conventional water sources. Water reuse and desalination were in focus in the study which was aimed to develop the strategies to promote the sustainable and safe use of reclaimed water and desalinat

A lot of attention has been focused on the policy stream of the multiple streams framework (MSF). John Kingdon used the role of the policy entrepreneur to theorize what was going on when problems become political issues. In order to fully grasp this process we need to further theorize also the problem stream. What is going on in the problem stream is defining the conditions for coupling done by po

Two movable-bed physical model experiments of breach growth in a sandy barrier were conducted in a 3.3-m wide, 64-m long flume with a wave generator capable of generating 0.5 m waves. Breaching was initiated both without waves (Case BR1) and with waves (Case BR2) in separate tests by maintaining a head across the barrier. Breach channel deepening was controlled by the head difference across the ba
