As with mosquitoes, female tabanid flies search for mammalian hosts by visual and olfactory cues, because they require a blood meal before being able to produce and lay eggs. Polarotactic tabanid flies find striped or spotted patterns with intensity and/or polarisation modulation visually less attractive than homogeneous white, brown or black targets. Thus, this reduced optical attractiveness to t

The MAX IV storage rings, currently under construction in Lund, Sweden, will use third harmonic cavities operated passively to lengthen the bunches and alleviate collective instabilities. These cavities are an essential ingredient in the MAX IV design concept and are required for achieving the final design goals in terms of stored current, beam emittance, and beam lifetime-such performance challen

Context: Despite the substantive societal impact of prostate cancer, the medical community is currently divided on the balance between benefit and harm of screening for prostate cancer using prostate-specific antigen (PSA). Objective: To examine whether PSA-based screening for prostate cancer meets current guidelines on efficacy and effectiveness for screening, and how it compares with other curre

Exploratory testing (ET) is a test technique used to test software. It is a free way (compared to scripted test) of testing, where the tester takes notes during the test session. The tester has the option to select his own way when testing the software, he learns and tests at the same time. Notes are the result from the test session and are used to see what has been tested, e.g. the outcome and th

Frågan om hur man bör se på straffansvar och påföljder för personer som begår brott under inflytande av en allvarlig psykisk störning är omdebatterade och därtill mycket komplicerad. Intresset av att personer som begår brott möts av en adekvat reaktion på brottet ställs här emot behovet av att tillräckligt beakta gärningsmannens psykiska tillstånd och behov av behandling. Principen att vissa persoThe question of how one should look at penalties and sanctions for persons committing crimes under the influence of a serious mental illness is controversial and very complicated. The interest in that people who commit crimes are met with an adequate response to crime is put up against the need to sufficiently take into account the offender's mental condition and need for treatment. The princi

As a consequence of the current global warming debate, many companies are today working towards minimizing their operations’ effect on the environment. The Swedish firm Ångpanneföreningen (ÅF), offers environmental consulting services through its EHS department (Environment, Health and Safety). The department’s largest business areas are services regarding state-regulated emission permits and meas

This project explored the usage and effectiveness of a natural water filtration system using xylem from Picea Abies, or Norway Spruce. The project is concentrated on the region of southeast and south Asia where people suffer from water contamination, providing a concept of a water filter with comprehensive protection against waterborne diseases. The study implemented secondary research on product

Den här studien ämnar att konstruera, testa och utvärdera ett lektionsmoment med fokus på talängslan. Momentet ska först och främst vara tidseffektivt och inte ta för mycket tid från övrig kursplanering. Det ska således gå att använda till exempel i slutet av en lektion utan att övrig undervisning blir lidande. Momentet ska även kunna byggas ut vid behov. För att utforma momentet intervjuade jag This research aims to construct, test and validate a lesson moment with the focus on effective work with speech anxiety in school. The lesson moment shall not take to much time or energy from the ordinary lesson plan. Therefore it shall be able to example to take place in the last minutes of the lesson. The moment itself also needs to be built upon over time and therefore be more advanced as the s

Människor följer ofta en liknande process när de söker sig till professionell vård. Upplevelser av vilka skäl de har för att söka rent faktiskt och vägen fram till att de tar beslutet att söka behövs det dock ytterligare forskning om. Därför är det viktigt att undersöka detta för att utröna människors upplevelse av vilka skäl och funderingar de har fram mot att beslutet att söka vård fattas. DettaPeople generally follow a similar process when seeking professional care. Experience of what reasons they have for actually seeking help and their considerations during the process before they make the decision to seek help is, however, insufficiently researched. Hence, it is important to study this in order to find out people's experience of what reasons and considerations they have during th

Aiding farmers with their tremendous task of sustainably and cost-efficiently feeding the world is of utmost importance. Information technology plays a crucial role in supporting farmers and supplying them with accurate information about their crops. The information gives farmers operative benefits, such as optimized timing of fertilization and plant protection to name a few. Satellite optical i

Addressing electronic waste is crucial for meeting the environmental needs of the 21st Century, as WEEE is one of the fastest growing waste streams. Spain has emerged as one of the top countries globally for per capita mobile phone consumption. For this reason, this thesis focuses on European and Spanish initiatives that am to improve the circularity of mobile phones through repair. In recent year

The purpose of our report was to analyze the effects of youth drug abuse on the families concerned. Youth drug abuse made us wonder about the effects on the family as a whole, of those involved with drug abuse. To answer this question, we decided to employ an empiric study in the form of interviews with four teenagers, five parents and four drug counselors. Because our intent was to understand rat

Copyright is a part of the intellectual property rights. This ancient occurrence became during 19th century observed by the legislation. Great economical interests and values made it necessary to create rules concerning how the exploitation would take place. Several important conventions were created during this century. For example, the Parisconvention (1883) and the Bernconvention (1886). During

The purpose of this essay was to investigate the opinions of young people, age 14-16, at a school in a middle-sized city in Sweden, concerning narcotics. The questions we asked ourselves were; -What are young peoples' ideas of narcotics? -What do young people imagine when they think of a drug addict? -What reasons do young people give to start using narcotics? -What gender-related opinions

This thesis investigates all aspects of quality and evaluation issues concerning collections of Internet links in public libraries today and in the future. We have studied central theories concerning quality in general as well as quality aspects regarding the Internet and Internet links. In addition to this we have made three case-studies involving the development of collections of Internet links

This thesis aims to offer insights into the initiation and development of modern (rural) bioenergy systems. For this reason, the thesis explores the formation, evolution and regional effects of three bioenergy projects ? a biodiesel cooperative, a biomass district heating plant and a biogas plant ? that are co-located within the small rural community of Mureck, in Austria. It finds that the three

There are different kinds of foam with varying stability and appearance and a number of factors which affect this. The volume and the stability of the foam are important for the beer industry due to the fact that many consumers find this a measure of quality. There are many different methods for measurement of the physical properties of beer foam. Unfortunately none is used as a standard. A method

The purpose of the study is to contribute with new knowledge regarding the present-day preservation of video in Swedish archives, more specifically video as recorded on magnetic tapes. In the study a distinction is made between magnetic tapes and VHS-tapes, as the colloquial use of the brand name VHS is often used to categorize all magnetic tapes. The research questions centre on how the preservat

This work applied Bayesian Optimization (BO) for the task of calibrating methane-related parameters in the Lund-Potsdam-Jena General Ecosystem Simulator (LPJ-GUESS v4.1). A Gaussian Process (GP) was used as the surrogate model within the BO framework. Additionally, other enhancements we applied to the BO framework such as the use of complexity-penalizing priors for GP hyperparameters and numerical

Safe and clean drinking water delivery is challenged by climate change, as elevated temperatures can promote the growth of pathogens and other detrimental microorganisms. The microbial processes underlying drinking water production in slow sand filters (SSFs) are largely uncharacterized, limiting the possibilities of improving this technology. Periodical clogging, potentially by microbes, disrupts
