The measurement and application of residual dipolar couplings (RDCs) in solution NMR studies of biological macromolecules has become well established over the past quarter of a century. Numerous methods for generating the requisite anisotropic orientational molecular distribution have been demonstrated, each with its specific strengths and weaknesses. In parallel, an enormous number of pulse schem
We consider a time-hopping impulse-radio system that uses transmitted-reference pulses for implicit channel estimation and equalization. A hybrid receiver structure first performs a filtering matched to the hopping sequence, and a subsequent correlation of the data pulses with the reference pulses. We analyze the performance of such a system both in AWGN and in multipath. For the AWGN case, we giv
This paper investigates the treatment of antonymy in Collins COBUILD Advanced Learner’s English Dictionary (2003) in order to find out what kinds of headwords are provided with antonyms as part of their definitions and also discusses the principles for antonym inclusion in the entries. CCALED includes canonical antonyms such as good/bad and dead/alive, as well as more contextually restricted pairi
Popular Abstract in Swedish Vi använder allt mer energi och efterfrågan kommer bara öka, fram till 2050 spås en fördubbling av världens efterfrågan av energi. Drygt 85 procent av den energi som produceras i dag kommer från fossila bränslen som bidrar till växthuseffekten. En ny rapport från FN:s klimatpanel, IPCC, visar att koldioxid står för runt 76 procent av det totala utsläppet av växthusgasAccelerating actions to mitigate CO2 emissions was one of the important messages at the UN Climate Summit 2014. About 85 % of the world’s energy is provided through the burning of fossil fuels, which is the main source of CO2 emissions. Increasing the share of renewable energy, and making energy efficiency improvements and savings were actions that were agreed upon to meet CO2 emission reductions.
Inom beredskapen mot radiologiska och nukleära olyckor och katastrofer spelar strålningsmätningar en avgörande roll för att ta reda på vad som har hänt och hur farligt det är för människa, djur och natur och på vilket sätt det påverkar miljö och samhällsfunktioner. I Sverige och många andra länder i världen har allmänheten en rättighet att få reda på vad som hänt och vad de utsätts för i ett eventThis thesis describes investigations made on mobile and stationary gammaspectrometry made both under laboratory conditions and in situ. The objective hasbeen to identify and quantify radionuclides in the form of point sources,contamination and widespread deposition in situations where the measurementgeometry is not known beforehand. Both scintillators and semiconductor detectors ofsimilar size wer
En skada i data innebär att data förloras eller förvanskas utan att detta sker till följd av en sakskada. Skadetypen härrör från Europaparlamentets och rådets direktiv (EU) 2024/2853 av den 23 oktober 2024 om skadeståndsansvar för produkter med säkerhetsbrister och är ny i förhållande till det gamla produktansvarsdirektivet rådets direktiv av den 25 juli 1985 om tillnärmning av medlemsstaternas laDamage to data means that data is lost or corrupted without this being the result of physical damage. This type of damage originates from Directive (EU) 2024/2853 of the European Parliament and of the Council of 23 October 2024 on liability for defective products and is new in relation to the old Product Liability Directive Council Directive 85/374/EEC of 25 July 1985 on the approximation of the l
The ongoing climate change is not only a challenge for the environment but also for economic and social development. The continuing rise of consumption and production of natural resources that needs to be preserved is affecting the environment. The urbanization is contributing to a higher demand of commercial buildings and housing, this needs resources like building material which releases carbon
In 2009, the Greenlandic population voted for full autonomy from Denmark; however, certain areas such as foreign and defense policy remain under Danish jurisdiction, with Denmark administering specific sectors, including the police force. Consequently, the Greenlandic Police is organized as a district within the Danish Police, resulting in a distinct structure that integrates both Greenlandic and
Klimatfrågan är en av de mest aktuella frågorna i dagens samhälle som upptar stort fokus inom många områden. Ett sätt att minska utsläpp och klimatpåverkan är att reducera samhällets energianvändning. Byggnader står idag för en betydande del av energianvändningen i samhället och är därför ett viktigt område för att nå uppsatta klimatmål. Vid nyproduktion av byggnader läggs stor fokus på att upprätIn 2019 buildings and services stood for 39 % of Sweden's total energy use. In new construction of buildings there is a great focus placed at establishing environmentally friendly buildings with good energy performance. But a large part of Sweden's property portfolio consists of older buildings where energy performance and comfort are low. Many of these older buildings also have a cultural
This thesis is a study of the possibilities of introducing freight trams on tram networks in cities and to examine the possibilities in Helsingborg as a concrete example. The city of Helsingborg has plans to in the next ten years start the building of a new tram network in the city, a measure implemented to increase the capacity of the public transport system and to improve the environment in the
Malaysia is one of the most developed countries in Southeast Asia, and strives to be acknowledged as a high income country by the year of 2020. According to Malaysian Environmental Quality (Sewage) Regulations from 2009 there are effluent limitations regarding nutrient emission from wastewater treatment plants. The company responsible for the municipal wastewater treatment, Indah Water Konsortium,
The surface mass balance determines the growth or decay of an ice sheet, by taking the difference between accumulation and ablation. In this thesis snow and ice ablation is related to 2m-temperature through the positive degree day method. The positive degree day method takes into account the ablation rate of snow and ice and the number of measurements with temperature above freezing level in order
At present there are no concrete guidelines how to calculate the pressure resistance capacity of the timber at the load perpendicular to grain. The test options ASTM, CEN and ICO gives three different results in testing of an equal body. With this knowledge the value for the characteristic compressive strength capacity of the pressure perpendicular to the grain will be reduced to 2.7 MPa. The reduc
Sammanfattning Den här uppsatsen är en granskning av brittisk, svensk och kanadensisk upphovsrätt. Mer exakt utreder detta arbete de olika ländernas syn på parodier och hur dessa skyddas under respektive lands upphovsrättslag. För att få en bättre förståelse för om parodier kan kvalificeras som upphovsrättsliga verk, berör även denna uppsats vilka olika kriterier varje land har satt upp för att Summary This paper examines the copyright laws of the British, Swedish and Canadian systems. More precisely it investigates the different countries views on parodies and in what way they are or aren’t protected under their Copyright Act. To get a better understanding of parodies and how they can qualify as a copyright work, this paper also deals with the different requirement each country has set
En omfattande samling koproliter från tre lokaler med sediment från sen kritatid i Münsterbassängen (nordvästra Tyskland) har studerats med en mängd olika analytiska tekniker med avsikten att belysa urtida trofiska nivåer och relationen mellan rovdjur och bytesdjur. Den fosfatiska sammansättningen, inneslutningar av benmaterial, storlek och form tyder på att de flesta eller samtliga koproliter pro
