Syftet med detta examensarbete var att undersöka och öka kunskapen om hur olika parametrar påverkar de dynamiska egenskaperna hos balkbroar i stål som används för gångtrafik. Stålbroar används ofta på grund av sin höga hållfasthet och låga vikt. På grund av de lägre statiska lasterna som orsakas av fotgängare är de dynamiska lasterna vanligtvis dimensionerande. För lätta broar med ett lågt förhålThe aim of this master's thesis was to investigate and increase the knowledge of how different parameters affect the dynamic properties of steel beam bridges used for pedestrian traffic. Steel footbridges are commonly used due to their high strength and low weight. Due to the lower static loads caused by pedestrians, the dynamic loads are usually decisive. For lightweight bridges with a low

This thesis employed several portable sensors on board an unmanned aerial vehicle (UAV) and manned aircraft in order to test new methods of measuring vertical profiles of aerosol particles and contribute to knowledge of aerosol distributions in the atmosphere. More data in this area is required to improve atmospheric modelling and future climate scenarios. The handheld nanoparticle detector Partec

Fatty acids-based herbicides are considered to be a green alternative to synthesized weed control products. However, the environmentally sustainable effect of those herbicides needs more investigation to be confirmed. The aim of this work was to develop a chemical analysis method that enables identification of short-chain fatty acids (SCFA´s) and medium-chain fatty acids (MCFA´s) in a commercial f

Detta är ett undersökande examensprojekt där jag vill översätta kunskap om goda lekmiljöer till fysisk form. I sökandet efter vad som definierar en god lekmiljö har jag formulerat följande frågeställning: ”Hur kan lekmiljöer gestaltas som samspelar med barns fantasi, uppmuntrar tankefrihet, är tillgänglig för alla barn och inte styrande i sin användning?” Jag har genomfört litteraturstudie och erfThis is an exploratory master’s thesis, where I want to translate theoretical and empirical knowledge of sound play environments to physical form. In the search of what defines a sound play environment, I have formulated the following question: ” How can play environments be shaped to enhance the interaction with children’s imagination, encourage freedom of thought, create accessibility to all chi

The GASMAS technique has previously proven useful for examining and measuring the oxygen concentration in the lungs of preterm infants. GASMAS can distinguish absorption by one gas from the bulk absorption of the surrounding media, and can provide an instant, non-invasive and non-destructive way of examining lungs, and diagnosing dangerous conditions such as pneumothorax. Pneumothorax can be life-

Varje år publicerar Socialstyrelsen en kartläggning av den svenska förlossningsvården. Kartläggningen heter “Statistik om graviditeter, förlossningar och nyfödda barn” och beskriver, bland annat, hur ofta den födande drabbas av en allvarliga bristning. Statistiken för hur ofta en allvarlig bristning uppstår i varje svensk region har skiljt sig mellan regionerna sedan 1990. Socialstyrelsen själva uEvery year the National Board of Health and Welfare (NBHW) publishes a survey of Swedish maternity care. The survey is called "Statistics on pregnancies, births and newborn children" and describes, among other things, how often complications in the form of severe tares affect women giving birth in Sweden. The statistics for how often a severe tares occurs in each Swedish region have diff

Den 1 juni 2022 trädde lagförslaget Modernare regler för användning av tvångsmedel i kraft. Med den nya lagstiftningen kan brottsbekämpande myndigheter nu förmå enskilda att medverka till biometrisk autentisering för att få tillgång till elektroniska uppgifter som är lagrade i avläsningsbara informationssystem. Om den enskilde vägrar att medverka till det kan polisen genomföra autentiseringen. DOn 1 June 2022, the bill 'Modernised rules for the use of coercive measures' entered into force. Under the new legislation, law enforcement authorities can now require individuals to participate in biometric authentication in order to gain access to scannable information systems. If the individual refuses to co-operate, the police can carry out the authentication. The new legislation rai

Problem gambling is a serious social problem that can have significant negative impacts on an individual's life in various ways. Considering that preventing and combating problem gambling is one of the stated goals in the Swedish social services act, it is essential for social workers to understand how problem gamblers view problems related to their gambling. In this study, I have examined how

Kina har under flera års tid varit en av världens snabbast växande ekonomier och utgör därmed en enorm potentiell marknad för svenska företag. Den ökande handeln och transaktionerna med Kina kräver förståelse för kinesisk kontraktsrätt, som ännu inte är särskilt välkänd eller studerad i resten av världen. Syftet med uppsatsen är att jämföra och analysera likheter och skillnader mellan svensk och China has for many years been one of the world's fastest growing economies and has enormous potential for Swedish companies.
