Avloppsreningsmetod för att rena dricksvatten Målet med dricksvattenrening är att bli av med oönskade ämnen i vattnet, så som sjukdomsframkallande bakterier och organiskt material. Detta säkerställer inte bara vattnets säkerhet utan också dess smak, lukt och utseende. Det finns flera olika metoder för att rena vatten, och vilken metod som används beror på vattnets kvalitet och ursprung, samt vilkAt the drinking water treatment plant (DWTP) at Ringsjöverket (Sweden, Stehag), where this project is executed, a process of rapid sand filter (RSF) and slow sand filter (SSF) is used as a part in treating surface water into drinking water. The Moving bed biofilm reactor (MBBR) is a simple and strong biological process that has been shown to be effective in treating polluted raw water from nitroge

Sjukdomsberättelser om bröstcancer kan bidra med nya aspekter i utvecklingen av individualiserad cancerrehabiliteringBröstcancer är den vanligaste cancersjukdomen bland kvinnor världen över [1, 2]. I Sverige drabbas mer än var tionde kvinna av bröstcancer under sitt liv [3]. Utifrån att prognosen vid bröstcancer har förbättrats, är det allt fler kvinnor som överlever eller lever längre med sin sju

Abstract in UndeterminedThis paper presents a qualitative thematic analysis of reader comments posted in connection to a series of articles published after Encyclopaedia Britannica’s announcement to forego its print edition. It shows how ideas of what information is, are entangled with ideas of what a certain medium is and does. Two research questions guide the analysis: 1) How are encyclopedias a

Popular Abstract in Swedish De optiska egenskaperna i våra sjöar och vattendrag förändras kontinuerligt. Näringsrika sjöar blir grumliga genom algblomningar och erosion gör vattnet grumligt av lerpartiklar. De senaste årtiondena vattnet också blivit brunare genom att mer humusämnen läcker från omkringliggande mark. Både grumligt och humöst brunt vatten försämrar fiskens siktförhållande, men det skVisual conditions are changing in several different ways. Some lakes are getting turbid due to eutrophication or erosion while others are getting browner due to brownification. These two types of visual degradation results in completely different optical properties of lakes. Turbid water scatter light which degrades image quality severely while brown coloured humic water mainly absorb light making

Popular Abstract in Swedish Inom jonstråleanalysen används en partikelstråle, vanligtvis av protoner eller alfapartiklar, med hög energi för undersökning av prov. Då dessa partiklar skjuts in i provet sker kollisioner, reaktioner eller annan form av växelverkan med elektroner och kärnor i provets inre. En del av dessa processer ger upphov till högenergetisk strålning som kan studeras med lämpliga In nuclear microprobe experiments, high resolution maps of the measured parameter, e.g. element- or mass distribution, in a sample can be produced with a variety of ion beam analytical techniques. The principle underlying all the techniques is that ions at MeV energies are used as projectiles to cause interactions with the target material. Because of the limited range of ions in matter, there is a

Popular Abstract in Swedish Cellulära mekanismer vid ischemisk tolerans Stroke, hjärntrauma, hjärnblödning och övergående hjärtstillestånd, leder till minskat blodflöde till hjärnan (ischemi) och orsakar hjärnskador. Mot denna skadeutveckling finns ännu inte något medel för kliniskt bruk. I djurexperimentella ischemimodeller har man kunnat skydda hjärnan mot ischemiska skador genom att utsätta hjäA brief period of sublethal ischemia in the brain induces resistance to a subsequent, otherwise lethal ischemic insult. This phenomenon is known as ischemic tolerance or preconditioning. A model of ischemic preconditioning in the rat brain using the two-vessel occlusion model of global cerebral ischemia was established. Using this model we have demonstrated that ischemic preconditioning protects t

With Habermas' theory of communicative action as the starting point, a theoretical model is devised to investigate the act of creative writing as formulated in interviews made with students and teachers on a university study program me in creative writing. This article explores writers' work procedures in a communicative network of institutional and everyday practices, in the light of established

Background: The receptors for advanced glycation end products (RAGE) are increased in atherosclerotic plaques. Soluble (s)RAGE decreases, whereas the extracellular newly identified receptor for advanced glycation end products (EN-RAGE) increases inflammatory responses mediated by RAGE. The aims were to explore whether sRAGE, EN-RAGE and the EN-RAGE/sRAGE ratio, were associated with the use of lipi

We make Deterministic Lateral Displacement (DLD) flexible by combining it with AC electrokinetics.

We have fabricated a silicon-glass two-phase droplet-based microfluidic system and implemented two-dimensional acoustic focusing prior to droplet generation as well as continuously throughout the whole system to increase particle detectability. Using acoustic focusing we have effectively minimized sedimentation of the encapsulated particles and thereby increased particle detectability by as much a

Direct and precise manipulation of sub-micron particles such as bacteria, platelets, organelles, microvesicles, exosomes or virus particles is challenging. We describe for the first time how acoustic streaming in the bulk can be efficiently reduced by introducing a density or compressibility gradient and that this enables focusing of 500-nm-diameter particles in a standard acoustophoresis channel.

G.Fast is a new standard for fixed broadband access that aims at achieving bit rates of 1 Gb/s over short copper loops. In order to give support to simulation, design and performance evaluation tests, the G.Fast recommendation presents examples of some wiring topologies and reference loops describing configurations expected to be found in real G.Fast deployments. Our work describes results of mode
