This paper discusses five major parameters in desalination, namely technology, raw-water, energy sources, cost and environmental effects. Both size and yield have grown rapidly in desalination plants due to high performance in technology developments in the last few years. Five different types of desalination technology are presented and bench-marked for long-term use: multistage flash evaporation

The present study examined the rheological blood velocity profile in the conduit femoral artery during rhythmic muscle contractions at different muscle forces. Eight healthy volunteers performed one-legged, dynamic knee-extensor exercise at work rates of 5, 10, 20, 30, and 40 W at 60 contractions per minute. The time and space-averaged, amplitude-weighted mean ( V-mean) and maximum (V-max) blood f

There has been little development regarding analysis of polonium (Po) in environmental samples since the 1960ies. This is due to the straightforward spontaneous deposition of this element on silver (Ag), nickel (Ni) or copper (Cu) without any radiochemical separation. For many years, no radiochemical yield determinant was used and it was generally supposed that the yield was 100% after two deposit

Popular Abstract in Swedish Trådlös kommunikation via radiosystem har närapå blivit en rättighet i dagens samhälle. Vi förväntar oss att internet inte ska vara mer fjärran än där vi senast lade vår ``smarta mobiltelefon''; antagligen inom armlängds avstånd. Strömmning av data ökar ständigt då vi nuförtiden själva vill bestämma när och var vi ska avnjuta, till exempel senaste säsongen i favoritseRadio systems, along with the ever increasing processing power provided by computer technology, have altered many aspects of our society over the last century. Various gadgets and integrated electronics are found everywhere nowadays; many of these were science-fiction only a few decades ago. Most apparent is perhaps your ``smart phone'', possibly kept within arm's reach wherever you go, that prov

Our everyday experiences show that the lack of needed information in various human affairs may give rise to consequences that we would like to avoid – e.g. the 2004 Tsunami in Southeast Asia. However, we still do not have a coherent theoretical body that addresses such experiences of information inadequacy as this changes everything in respect to the current conception of the information society,

DTLS is a transport layer security protocol designed to provide secure communication over unreliable datagram protocols. Before starting to communicate, a DTLS client and server perform a specific handshake in order to establish a secure session and agree on a common security context. However, the DTLS handshake is affected by two relevant issues. First, the DTLS server is vulnerable to a specific

BACKGROUND: Recipient age and donor age are well-known prognostic factors in adult heart transplantation. However, the association between donor age and recipient age and their interaction and short- and long-term mortality is unknown. METHODS: We studied 64,354 heart transplants to adult recipients between 1988 and 2013 in the ISHLT Registry. Donor age and recipient age were analyzed as continuou

The primary goal of this workshop was to identify the most appropriate method to estimate the potential effect of reduction in sodium consumption on mortality. Difficulty controlling hypertension at the individual level has motivated international, federal, state, and local efforts to identify and implement population-wide strategies to better control this problem; reduction of sodium intake is on

The global environment suffers from utilizing fossil fuels to powering internal combustion engines (ICE), due to the massive amounts of released CO2. Besides the global impact, the local environments experience high concentrations of harmful pollutants such as NOx, CO, soot and particulate matter (PM). The automotive industry is continuously striving to find new solutions to decrease fuel consumpt

BACKGROUND: Triticum aestivum (wheat) is one of the world's oldest crops and has been used for >8000 years as a food crop in North Africa, West Asia and Europe. Today, wheat is one of the most important sources of grain for humans, and is cultivated on greater areas of land than any other crop. As the human population increases and soil salinity becomes more prevalent, there is increased pressure

Sustainability philosophers claim that we are at an impasse of stories, finding ourselves in a blank chapter between the old and the new. The old story, characterized by separation, technological dominance and human superiority over nature, is unfolding in an ecological crisis giving space for a new narrative defined by inter-being, cooperation and balance. It has been put forward that this crisis

Today, one of the most important questions around the world is that of climate change and the battle against carbon emissions. Wind power has proven to be the most successful option among renewable energy sources, and it is a crucial tool in the race to cut our carbon emissions and to safe security of supply within the EU. Until now, most of the development has occurred onshore, but offshore wind

A sustainable development was defined by the Brundtlandscommission for the United Nations Conference on Environment and Development as "... a development that meets present needs without compromising future generations to meet their own needs". The definition includes a broad consideration of economic, environmental and social aspects. The definition thus creates a good example of the

Prosolviadomen innebar det största skadeståndet någonsin utdömt i Sverige. Det tar upp frågan om revisorns skadeståndsansvar gentemot bolaget, men också frågan om prövningen av orsakssamband. Hovrätten tillämpade i målet en bevislättnad för den skadelidande efter ett prejudikat från Högsta domstolen som kom ut samma år, 2013. Revisorn som kontrollerande organ i aktiebolaget har som uppgift att tThe Prosolvia judgment came with the largest damages ever imposed in Sweden. It addresses the issue of accountant-liability towards the company, but also the issue of the assessment of causality. The Court of Appeal applied in the case, an evidence-relief to the injured after a precedent from the Supreme Court which came out the same year, 2013. The accountant as the controlling body in the compa

Close to the city center of Reykjavik lies the combined national- and university library of Iceland. Usually, these two types of institutions are separated. The purpose of this essay is to investigate how the library in fact selects the new digital material to offer the users in Iceland, and if the combined mission creates any problems or conflicts. The investigation examines the planning and the

Sweden is the only Scandinavian country that uses closed treatment institutions based on coercive measures within the child welfare system, on a large scale, for the education and treatment of young criminal offenders and drug users. In Sweden there are in 2002 some 30 “homes for specialized supervision” of varying sizes and degrees of specialization – all run by a national board of institutional
