Use of LCA for buildings

The increasing focus on the environmental classifications and energy certification systems as well as LCA in the building industry nowadays has raised the interest in the life cycle perspective of buildings among countries, municipalities, builders and researchers. This thesis shows how Sweden is dealing with this topic comparing to the Netherlands and Turkey. By presenting a detailed literature

More misses than matches in the phenological synchronicity of urban passerines?

Late to the Party—Phenological Mismatches in Passerines Spring arrives earlier in the city than it does in the countryside. The buildings trap heat, and the lack of green spaces means there aren’t enough plants to cool down the air through evaporation. This is known as the Urban Heat-Island effect (UHI). In Malmö the temperature increase is modest—in fact, it’s just about 1 °C warmer than in Skr

Short Range Gesture Sensing and Classification Using Pulsed Millimeter-Wave Radar and Convolutional Neural Networks

A millimeter-wave radar setup utilizing a pulsed Resonant-Tunneling Diode signal generator in the 60 GHz ISM band is used to measure 12 different hand gestures. The data is used to train and validate Convolutional Neural Networks (CNNs). The measurement setup utilizes a real time sampling oscilloscope and down-mixing o

Hellre fria än fälla? - En uppsats om polisers brott som grund för avskedande

Denna uppsats behandlar polisers anställningsskydd och de avvägningar som gjorts i fall då poliser gjort sig skyldiga till brott, i förhållande till allmänhetens förtroende. Vid bedömningen har särskild vikt lagts vid att undersöka de aspekter som föranlett avsked och hur bedömningen gjorts för att fastslå avskedet. I uppsatsen har den rättsdogmatiska metoden använts för att utreda rättsläget. SoThis essay aims to discuss the Swedish legislation regarding dismissal of policemen on the grounds of a criminal offence. Furthermore, the considerations made by the Labour Court and personalansvarsnämnden vid polismyndigheten (PAN) in relation to public confidence will be discussed. In the assessment, particular emphasis has been placed on examining the aspects that prompted the dismissal. The tr

Vulkanisk inverkan på klimatet och atmosfärcirkulationen : en litteraturstudie som jämför vulkanism på låg respektive hög latitud

Vulkanisk aktivitet har sedan längre observerats ha en stor påverkan på klimatet. Svavelaerosoler från utbrott bildar molntäcken som kan sprida sig runt globen och hindrar en del solstrålar från att nå markytan. Till följd av detta sker en temperaturminskning av marknära luft under det område som molnet täcker. Den här kandidatuppsatsen reder ut skillnaden mellan inverkan på klimatet samt atmosfärVolcanic activity has long been observed to have a great impact on climate. Sulfate aerosols from an eruption form aerosol clouds that can spread around the globe and prevent some solar radiation from reaching the surface of the Earth. As a result, there will be a reduction of the surface air temperature below the aerosol cloud. This bachelor thesis discusses the difference between the impact on t

Innovera mera - En kvalitativ studie om styrning och innovation i en svensk kommun

Under en längre tid har svenska kommuner präglats av en målstyrd verksamhetsstyrning där kontroll, mätning och uppföljningar funnits vid varje målsättning. Samtidigt satsar den offentliga sektorn på innovationsarbetet för att kunna utvecklas i takt med omvärlden. Trots detta finns det en problematik med innovationsutvecklingen då den ofta förknippas med andra branscher och tekniska uppfinningar. D

Korslimmat trä – Optimering av tvärsnittsuppbyggnad

Korslimmat trä, KL-trä, är ett förhållandevis nytt byggnadsmaterial i byggbranschen. Det består av ett udda antal skikt av lameller av konstruktionsvirke, där varje skikt av lameller ligger roterade 90 grader i förhållande till intilliggande skikt. Materialet används både i den bärande stommen och som stomkomplettering i form av exempelvis trappor. Idag finns endast en etablerad tillverkare på dCross-laminated timber, CLT, is a rather new building material. It consists of an odd number of layers consisting of lumber boards stacked together, where each layer is rotated 90 degrees in comparison to the adjacent layers. The material is used both as a load-carrying element as well as a non-load-carrying element, such as stairs. Today there is only one established producer of CLT in Sweden. D

What Comes First - Strategy or Structure?

The Political Economy of Universal Primary Education

The idea of Universal Primary Education has always been an essential part of the core concept of development. Whether gained through formal or informal channels has played relatively a little role, as long as the end-result has been an individual, who has obtained the basic level of schooling. The concept of quality education however, has not been the focus of this basic education until only recen

Welcoming Change? An Individual- and Prefecture- Level Analysis of Public Opinion towards Immigration in Japan

In April of 2019, Japan implemented a new visa system projected to bring in approximately 345,000 semi-skilled foreign workers into the country over several years. As the Japanese society also faces an ageing population and simultaneously a diminishing workforce, it has turned to immigrant workers to fill labor shortages. This influx of foreigners may result in cultural, societal, and economic iss

Probabilistic ecological risk assessment of secondary poisoning from DDT

Fallstudie av en skogsplantskola – rester av DDT i jorden utgör än idag en hög risk för rovfåglar och rovdjur. Trots att användningen av insektsgiftet diklordifenyltrikloretan (DDT) sedan länge varit förbjuden i Sverige finns rester kvar i jorden på platser där det använts. Anledningen till att det finns kvar är att DDT är mycket svårnedbrytbart. Eftersom detta ämne även har förmåga att bioackumuAlthough prohibited since decades, dichlorodiphenyltrichloroethane (DDT) and its metabolites still remain in the soil and pose a threat to ecosystems, where especially birds are susceptible to toxic effects. In this thesis, a model developed in the 1990s was used and updated in order to estimate the risks of DDT to top predators at a forest-plant nursery site. Unusually high concentrations of DDT
