Ökengräshoppan är ett väldigt litet djur men de kan skapa stora problem när de ökar i antal och samlas i svärmar. Plågorna från dessa är kända sedan bibliska tider men med ett utbrott så sent som 2020 så är ämnet lika relevant idag. Gräshopporna utgör ett hot mot jordbruk, och i förlängningen tillgång till mat, genom sin stora aptit, varierade kost och förmåga att förflytta sig långa sträckor. DetThe knowledge of desert locust plagues goes back to biblical times but it is just as relevant in 2020 with an ongoing outbreak in East Africa and the Middle East. The locusts pose a threat to agriculture, and by extent food availability, due to their high appetite, diverse diet and ability to migrate long distances in large swarms. More knowledge of the aftermath is required by the international d

Fordonsindustrin elektrifieras just nu i en snabbare takt än någonsin. Allt från elektriska cyklar till Segways och elektriska longboards. Alla dessa kräver nya sorters interaktioner för att styra motorn. Segway har till exempel utnyttjat användarens lutning som ett medel för att bestämma om personen vill åka fram eller bak. Elektriska longboards använder sig ofta av en handhållen kontroll med en The automotive industry is now electrifying at a faster rate than ever before. Everything from electric bikes to Segways and electric longboards requires new kinds of interactions to control the engine. For example, Segway has used the user's tilt to decide whether they want to go forward or backward. Electric longboards often use a handheld controller that has a gas button. Now, this electrif

The discovery of penicillin and the many antibiotics after that, has given our society a heightened sense of confidence when dealing with everything from the everyday bacterial infection to complicated surgical procedures. However, more and more bacterial species are becoming resistant to antibiotics. 33000 deaths attributed to antibiotic-resistant bacteria occurred in Europe in 2015, a number tha

Title: Abnormal return in the event of an equity issuance – A comparison of rights issues and directed share issues Seminar date: 2021-01-14 Course: FEKH89 – Business Administration, Degree Project Corporate Finance, Undergraduate Level, 15 ECTS Authors: Fredrik Eriksson Oppliger, Erik Olshov, Gustav Persson, Alex Skepastianos Supervisor: Håkan Jankensgård Key words: Event study; Efficient-m

Tröger’s base molecule has a unique V-shaped cavity and a chiral structure. These molecules can be fused together in a linear fashion to create either tubular structure or zigzag structure. Different fields can be benefited from the applications of these molecules. Previous studies carried out in the Wärnmark group led to 30-step synthesis route to get a linearly fused heptakis-Tröger’s Base anal

Wet lamella clutches are used in the automotive industry to enable all-wheel drive and thereby increase acceleration, handling and safety of cars. The clutches work by transmitting torque from an incoming- to an outgoing shaft through a series of lamella - steel-disc friction surfaces (lamella pack), lubricated by an oil. Based on temperature- and wheel-speed measurements, a mathematical model of

Största delen av det svenska vägnätet består idag av belagd väg. Med det i åtanke så krävs det därför att vägarna vid sin anläggning respektive när underhållsåtgärd sker blivit väl dimensionerade samt blivit korrekt utförda. Under en tid i Sverige har Trafikverket med sitt dokument TRVK väg numera TRVINFRA styrt hur de statliga vägarna skall dimensioneras med sina tre dimensioneringsklasser. I dirThe largest part of the Swedish state roads are today paved. With this in mind it is therefore demanded when a road in question is constructed respectively when a maintenance measure is taken place that the dimensioning of the road from the start was done properly. Since a while back in Sweden it has been upon the Swedish Transport Administration to regulate with their document “TRVK Väg”, now TRV

This research paper investigates notions and values that composers have regard to artificial intelligence and composition. The research is based on a survey that was sent to students and teachers of composition at Malmö Academy of Music. A total of 32 emails were sent, of which 15 were answered. 12 of the informants were students and 3 were teachers. Of the 32 individuals surveyed, the number of t

Power system infrastructure has been facing many challenges when it comes to harmonics distortion, and power electronic devices are no exception considering their wide usage in the system. In this thesis the focus is on the impact of these system harmonics on the electrical motors which are vastly used in industry for different applications. Motors usually come with a softstarter, and are connecte

Syfte: ​S​yftet med studien är att undersöka kulturell påverkan av kreativa inslag i standardiserad reklam. Med studien vill författarna bidra marknadsföringsbyråer med en utökad förståelse för hur den kultur som är associerad med landet inom vilken byrån agerar kan ha en omedveten påverkan på produktionen av reklamfilm. Metod: ​I studien utför författarna en semiotisk innehållsanalys av standardiPurpose​: The purpose of the study is to investigate the impact that a country's culture has on the use of creative elements in standardized advertising. Thus contributing to the understanding of how the culture associated with a country in which a marketing agency operates can influence their production of commercials. Methodology: The study is a content analysis of standardized commercials p

Climate change is the greatest challenge of our time. Despite efforts to reduce greenhouse gas (GHG), the emissions contribution from global aviation is set to increase. Electric aviation has emerged as an alternative which could form part of the solution. Sweden, which is on the path to carbon neutrality and has a long history in aviation, could contribute to the global efforts in mitigating clim

Unfriending someone on Facebook is a phenomena which can be seen in many different contexts and unfriending someone for political reasons can create obstacles for political conversations as it can increase polarization in society. In recent years there has been a tendency of unfriending individuals that express sympathies for the political party Swedish Democrats (SD) which can be perceived as sti

The contribution of greenhouse gas emissions in the production of construction materials has sparked a new interest and recent changes in building regulations regarding the use of renewables like wood as the main component in load-bearing elements. Recent regulation changes focus on allowing taller timber structures which bides the question of how to adequately maintain an acceptable level of f

Less than a decade ago, Swedish law demanded that a person who wanted to change their legal gender had to be without any ability to reproduce. This demand led to many trans people being forcibly sterilized. Even though the demand is now removed from law, lingering effects continues to affect trans people in their reproductive journey. This study examines barriers faced by trans people in three sta

Denna studie har utforskat kvällspress (Expressen och Aftonbladet) och myndigheters (Folkhälsomyndigheten och Regeringen) strategiska kommunikation under coronapandemins inledande fas i Sverige och analyserat detta dels baserat på kriskommunikationsteori, dels dagordningsteori med gestaltningsteori och teorin om den retoriska arenan. För att kunna genomföra en Retorisk Arena-analys på materialet iThis study has explored the strategic communication of The Public Health Agency of Sweden and the Swedish Government compared to tabloid press of Sweden (Expressen, Aftonbladet) during the initial phase of the coronapandemic in Sweden and analyzed it based on crisis communications theory, partly agenda-setting-theory including framing theory and the theory of the Rhetorical Arena. In order to comp

Wheat bran is a by-product from the production of wheat flour. Nowadays wheat bran is mostly used as feed for animals, in the food and baking industry or it is simply burned in open air. However, wheat bran could be used in biorefineries for production of value-added products such as bioplastics, biofuels and chemicals as a substitute for fossil feedstocks as petroleum. Since wheat bran is an agri

Over the last few years, there has been a proliferation of different kinds of movements across the globe as citizens agitate for economic, socio-political and environmental change. In the Democratic Republic of Congo (DRC), where the country has been involved in a series of wars, attention has rather been eschewed towards the rape and sexual violence of women and girls. Using post-colonialism and
