Vid läkemedelsutveckling används proteiner vars funktion är beroende på hur det är veckat (dess konformation). Denna veckning påverkas i sin tur av vätebindningar från vatten, som bildar vätskemiljön i kroppen där medicinen ska verka och styrkan av vätebindningar påverkas i sin tur av vattenmolekylernas orientering kring proteinet. För att kunna förutse proteinets funktion i kroppen är det därför A protein’s function is directly related to its structure, which is in a water medium where it is affected by hydrogen bonds and the hydrophobic effect. These interactions are in turn dependent on the water molecules’ orientations around the protein. Therefore, it is vital to have correct orientations for the water molecules. Such information can be obtained by neutron crystallography. However, ev

I detta arbete undersöks hur musiklärare på gymnasiet ser på bedömningsuppdraget kopplat till de anvisningar som ges i läroplanen. Syftet är att ta reda på hur musiklärare upplever tydlighet i dessa anvisningar. Det syftar också till att jämföra tolkningar av kunskapskraven, samt öppna upp till diskussion om vad som är viktigt för att ha ett bedömningsarbete som håller en hög kvalitet. Metoden somThis study examines how music teachers in upper secondary school view the assessment assignment in aspect to the instructions given in the curriculum. The purpose is to find out how music teachers experience clarity in these instructions. It also aims to compare interpretations of knowledge requirements, and open up for discussion about what is important for high quality assessment work. The metho

Genom att ta bilder i specifika våglängder på växer, från det visuella till det osynliga, kan man ta reda diverse information om växter såsom biomassa och stress. Detta kan man då göra med multispektrala kameror som oftast har varit monterade på satelliter. Satelliter har dock problem såsom eventuella molntäcken som täcker vyn över växterna. Drönare med multispektrala kameror har därmed blivit all

The aim of this study was to examine students gaming habits and what function playing computer games fulfil for students. The study was conducted with the help of a survey methodology and was sent to 500 students at Lunds university. The students got selected via an unbound random selection. 52 participants answered the survey. They majority of students plays computer games. Regarding those who pl

In recent years, discussions regarding problematic school absenteeism have increased in research and media. The Swedish National Agency for Education (Skolverket) observed an increase in both valid and invalid absences among students attending compulsory school in 2023, compared to previous years. Using Michael Lipsky's theory of street-level bureaucrats, which encompasses alienation, discreti

STUDY QUESTIONDoes endometriosis and/or adenomyosis, diagnosed using the International Deep Endometriosis Analysis (IDEA) group and the Morphological Uterus Sonographic Assessment (MUSA) group revised definitions, impact cumulative live birth rates (CLBR) after three consecutive IVF or ICSI treatments?SUMMARY ANSWERWomen with endometriosis and/or adenomyosis, as diagnosed using transvaginal ultras

Which of the many available theories of consciousness should a newcomer to the field choose? We consider possible ways to deal with this conundrum. We argue that convergence of theories is unlikely. Next, we consider ways comparing theories highlighting significant issues with existing endeavors in this regard. Given the nature of the field, presumably empirical support has a critical role to play

Entrepreneurial marketing has proven to be important for a brand's survival in a fiercely competitive market. A well-communicated brand identity contributes to positive brand awareness, brand attitudes and legitimacy, which are important elements for a successful brand. There are some communication strategies for well-established companies, but to our knowledge, there is a lack of research on

Social media has taken a prominent position in our society and is constantly debated in media; warnings are mixed with promises of big opportunities. Young people writing about fashion and every day life make big money, politicians seek online for voters and big companies have found a new way to interact with their customers. Publishing houses and writers are forced to find their place in this new

Inom kärnkraftsverken, läkemedelsindustrin, biotekniklaboratorier mfl är det vanligt att det radioaktiva ämnet 14C förekommer i olika former. Inom kärnkraftsverken som en biprodukt vid elproduktion och inom läkemedelsindustrin används det som markör för att studera hur sunbstansen distribueras i kroppen. Genom inandning vid t ex oförsiktighet kan de människor som arbetar med dessa olika substanserWith the help from accelerator mass spectrometry (AMS), hair from workers within the nuclear power industry, pharmaceutical and biotechnology industry has been investigated to see if contamination from 14C. 14C-using companies and nuclear power plants were contacted, volunteers were recruited, who sent in hair samples together with a questionnaire. The samples were washed and prepared for 14C anal

The topic of this thesis is to study which women are represented in hair-adds, -advice and -articles. Also, to study in what way representation has changes from 1970s to 21st century. The study is based on eighty-seven volumes from the magazine Veckorevyn from the period 1970-2000. The results shown that representation is mainly white woman, and this reflecting how society views women of other nat

Important questions for our study were: What do sports mean to teenagers? What thoughts do teenagers have about demands and expectations in sports? What thoughts do teenagers have about doping? What do teenagers think about information on dop

The aim of this thesis is to explore the job satisfaction of librarians and try to nuance stereotypes, which the public has and which still exist in massmedia concerning librarians and their work. The study is qualitative and based mainly on semistructured interviews with ten libraries born between 1937s and 1973s of which eight are women and two men. Furthermore, I have divided them into two grou

Problem: More information is needed on how a company can overcome hardship during stormy business cycles. Appropriate management strategies on how to get the business going as the dust settles is essential in order for a company to sustain on the market. Management in any recession is difficult, especially in today´s turmoil. Nonetheless, corporate strategic renewal is needed to mitigate the risk

The aim of the chapter is to present aspects of generation and gender in relation to ecological behaviour in Sweden. Past studies have compared age groups, sexes or some other classified groups in relation to attitudes and behaviour. The studies present an empirical overview. To get a deeper understanding of attitudes and behaviour we are in need of theoretical renewal with references to both clas

Background: At birth, infants' lungs are fluid-filled. For newborns to have a successful transition, this fluid must be replaced by air to enable effective breathing. Some infants are judged to have inadequate breathing at birth and are resuscitated with positive pressure ventilation (PPV). Giving prolonged (sustained) inflations at the start of PPV may help clear lung fluid and establish gas volu

Best use of scientific knowledge is required to maintain the fundamental role of seafood in human nutrition. While it is acknowledged that genomic-based methods allow the collection of powerful data, their value to inform fisheries management, aquaculture, and biosecurity applications remains underestimated. We review genomic applications of relevance to the sustainable management of seafood resou

What is sex work? I have decided to start this short contribution with a question, which I think the reader should answer before continuing. So what is sex work? Is it a legitimate form of work or is it a job whose only characteristics are exploitation, harassment, and coercion? Also, can a person (woman or man) freely decide to be a sex worker or is it impossible to engage in such profession with
