The wildlife park Kolmården in Norrköping, Sweden, asked for a device that could visually feedback how dolphins use their ultrasound signals while echolocating objects. By recording the sound from the dolphin, process the sound and then create a visual feedback by having LED's flash in different frequencies, depending on the distance between dolphin and device. The purpose of the device is havVisual response to dolphin echolocation It is well known that dolphins use echolocation but how about watching what actually happens? A device that shows the audience some of the information contained within the emitted ultrasonic waves. It is a small fish look-alike device that is created to simulate how the dolphins behave while hunting. By picking up the echolocation signals sent out from the

Up to recently mobile gamma spectrometry has mostly been performed with NaI(Tl)-based detector systems. However lately the interest of using HPGe(High Purity Germanium)-based systems have increased and one has realised that the excellent energy resolution of HPGe-detectors, in combination with the possibility to manufacture larger crystals than before, is an advantage not only when performing in s

We've long focused on the green transition, discussing various systems emphasizing the technical aspects of transitioning our lives. Yet, as many people experience anxiety about climate change, other, more existential perspectives are rising to the surface. Questions such as What is a good life? becomes more pressing as we begin to feel the effects of climate change also in our part of the world.

Popular Abstract in English Deoxyribonucleoside triphosphates (dNTPs) are the building blocks of DNA and the balanced cellular dNTP pools are of extreme importance to maintain the genomic stability and overall function of the cell. Primarily, two different pathways exist in most of the organisms that are responsible for providing dNTPs. One is called the de novo pathway where dNTPs are formed fromThe synthesis of deoxyribonucleoside triphosphates (dNTPs), building blocks of DNA, can be achieved by two different pathways in the cell. One is called de novo synthesis and the other is known as salvage pathway. The de novo pathway involves synthesis of dNTPs by utilizing basic molecules like sugars, amino acids, CO2, NH3, etc., while in the other pathway, dNTPs are formed by salvaging intra- or

Cities today consume over 80% of the world’s energy and are responsible for 75% of the total GHG emissions. Over 80% of the population in Europe live in Urban areas. The mobility system, being at the heart of urban activities is responsible for the movement of people, goods and services and is responsible for attracting investments into cities. Playing such a key role in urban development, the sec

During the 1970s, vocabulary knowledge was a central topic within the field of Swedish sociolinguistics, often discussed from a democratic point of view focusing on inclusion and accessibility in the society. This study links up to this tradition by reporting a survey of how the vocabulary knowledge has changed over time in Sweden, building on data from theSwedish Scholastic Aptitude Test (SweSAT)

Popular Abstract in English Alcohols and aldehydes are used in the chemical industry largely as a starting material for the manufacture of a wide range of products. They are also used as such in various industrial applications. The flexibility is due mainly to the functionalities of the alcohols and aldehydes being hydroxylic and carbonylic, respectively. Much interest is directed nowadays at convNowadays, transition metal oxide catalysts are employed to a large extent in many chemical processes for the selective production of chemicals and intermediates. Although metal oxides are mostly known as oxidation catalysts, they can successfully catalyze a wide range of reactions, such as dehydration. Two different processes have been studied in the present work: the selective oxidation of methan

Socio-economic shocks, technogenic catastrophes, and armed conflicts often have drastic impacts on local and regional food security through disruption of agricultural production and food trade, reduced investments, and deterioration of land and infrastructure. Recently, more research has focused on the effects of armed conflict on land systems, but still little is known about the processes and outSocio-economic shocks, technogenic catastrophes, and armed conflicts often have drastic impacts on local and regional food security through disruption of agricultural production and food trade, reduced investments, and deterioration of land and infrastructure.

Research evaluation practices linked to social impact have important systemic effects on the prioritization and organization of research while at the same time leading to the delivery of higher social value. Amidst growing criticisms, global research evaluation has evolved in a different direction, characterized by quantitative metrics and mimetic behavior. The article deals with the forces that s

In my thesis I have chosen to immerse myself in the regional power line network and how it will be built. I have chosen this topic because it is a significant question today and in the future. The investments and technical choices made today, will affect the outcome on the society of tomorrow. When the local power line network was rebuilt, after the hurricane Gudrun in the year 2005, it implied a

Emulsion formation by homogenization is commonly used in food production and research to increase product stability and to design colloidal structures. High-energy methods such as high-pressure homogenizers and rotor–stator mixers are the two most common techniques. However, to what extent does the research community understand the emulsion formation taking place in these devices?

The procedure within the administrative field of law is ruled by norms and principles. The framework governing differs from the procedural law in civil court. The grounds for administrative claims and appeal are established in 29 and 30 §§ FPL. There are also a number of other procedural laws with their own rules for appeals, to which FPL is subsidiary. Amongst the other laws is the law that regul

During the 15th, 16th and 17th century many commodities were traded from east to west and vice versa through The Sound. One commodity of great importance was cloth. To these large quantities of cloth lead cloth seals were attached as a hallmark of quality control. In this study the cloth trade between the Netherlands and Scania during the Late Middle Ages and Early Modern Times is investigated for
