During the last decade, a new design of schools with fan assisted natural ventilation has been introduced. Experience and knowledge of this type of ventilation system is therefore needed. The objective of the project is to study the technical and physical conditions required to ensure satisfactory ventilation. The whole project includes analyses of the air flows for different combinations of outdo
This report is the result of a joint research project between Lund University and Copenhagen Business School, mainly financed by the Öresund University. The main research question was: Can the Öresund region position itself as a leading logistics centre in Scandinavia, in the light of the new conditions that the bridge brings? The purpose was to create a fundamental understanding of the new logist
Popular Abstract in Swedish Växters fenologi påverkar ekosystemens funktion och tjänster, och återkopplar till klimatet genom att påverka utbytet av kol, vatten och energi mellan atmosfär och ekosystem. Under de senaste decennierna har växternas fenologi studerats i allt större omfattning, men fortfarande är osäkerheten stor och enighet saknas om klimatets inverkan på fenologi och förändringar övePlant phenology exerts major influences on carbon, water, and energy exchanges between atmosphere and ecosystems, provides feedbacks to climate, and affects ecosystem functioning and services. Great efforts have been spent in studying plant phenology over the past decades, but there are still large uncertainties and disputations in phenology estimation, trends, and its climate sensitivities. This
Håkan Wallander is a professor in Soil Biology and the reader is guided through the fascinating world below ground. The book has a free form and the author mixes scientific facts with personal stories from active research experiences and everyday life. The main focus is to make the reader aware of the vast biodiversity that exists in the soil, and to describe the important processes provided by th
The Swedish Armed Forces have traditionally been exclusively male, and service in the cause of defending the country has until recently been the privilege of men. While the very first women entered the military 37 years ago, the military has so far failed to fully integrate women into the organization and promote gender equality. The object of this study is to probe servicewomen's meanings, identi
Pollinators are critical for food security; however, their contribution to the pollination of locally important crops is still unclear, especially for non-bee pollinators. We reviewed the diversity, conservation status, and role of bee and non-bee pollinators in 83 different crops described either as important for the global food market or of local importance. Bees are the most commonly recorded c
In performance contexts, costume is often perceived as visual expression that is in service of, for example, a choreographer’s vision. I argue that costume is also an aesthetic and poetic language in its own right that allows individuals such as performers and designers to co-conceptualize and co-create performances. In co-creative performance-making processes, I argue that it is critical that des
Artikeln argumenterar för en förnyad relevansen för tidsgeografi iturism i ljuset av mobil teknikanvändning och allestädes närvarandedigital uppkoppling. Uppsatsen föreslår begreppet fygitalitet för attförstå hur digital teknik används i det fysiska rummet, ochhur samspelet mellan det fysiska och det digitala omformasi turisters projekt, rutter, kopplingar och begränsningar. Det teoretiskabidragetThe paper argues for the renewed relevance of time geography in tourism in light of the use of mobile technologies and ubiquitous connectivity. The paper proposes the concept of phygitality to understand how digital technologies are used in physical space, and how the interaction between the physical and the digital reconfigures tourists’ projects, paths, bundles, and constraints. The theoretical
Det finns idag ett växande intresse för psykologisk forskning för att se hur skamkänslan påverkar individer som befinner sig i en utsatt situation i vårt välfärdssamhälle. I ett försök att belysa hur den enskilde tjänstetagaren upplever bemötandet från myndighetspersoner har ett kvalitativt synsätt använts i denna studie. Med hjälp av ett hermeneutiskt förhållningssätt genomfördes sju semistrukturThere is today a growing interest in psychological research to see how the feeling of shame affects individuals who are in vulnerable situation in our welfare society. In an attempt to shed light on how the individual servicerecipient experiences the treatment from government officials, a qualitative approach was adopted in this study. Using a hermeneutic approach, seven semi-structured interviews
Förtätning och byggande i urbana miljöer innebär stora utmaningar för alla inblandade parter, stadens invånare, verksamheter och besökare. Låg effektivitet- och produktivitetsutveckling i byggbranschen, tillsammans med ökade miljökrav är ett par av de främsta utmaningarna. Krav på effektiv ytanvändning förutsätter en välfungerande, effektiv logistik och materialhantering, med minimal påverkan på dDensification of cities and construction in urban environments poses major challenges for all parties involved, the city's residents, businesses and visitors. Low efficiency and productivity development in the construction industry, together with increased environmental requirements are a few of the main challenges. Requirements for efficient use of surface demands efficient logistics and mate
While covid-19 has limited our travels, so many people around the world travel for professional purposes whether they work for a large corporations, on oil rigs, in the military, or in remote research bases. How do these individuals find comfort while they are abroad? After interviewing two different people who travel for professional purposes it was found that accommodation doesn’t provide the be
As a complementary product to the Tetra Brik Aseptic packaging system, Tetra Pak is about to introduce a new, value added, aseptic packaging system called SCAP. The SCAP packages consists of a lower part made of carton and an upper part made of plastic, similar to a PET-bottle, resulting in a bottle shaped package. The purpose of this thesis is to design a logistical- and material-handling system
En geologisk turistguide över Söderåsen i Skåne har utarbetats i samarbete med Svalövs kommun. Syftet med guiden är att öka kunskapen om Söderåsens unika geologi samt tipsa om geologiskt intressanta besökslokaler inom området. Information om geologi och lokaler har inhämtats via skriftliga publikationer, från Sveriges geologiska undersöknings (SGU:s) kartblad med beskrivningar samt genom dokumentaA geological tourist guide to Söderåsen in the province of Scania, southern Sweden, has been made in collaboration with Svalövs municipality.

Equal participation in safe and decent work is a crucial factor for achieving gender equality. Despite this, gender-based obstacles remain as workplaces often fail to ensure the human rights, health, and general wellbeing of their employees, with menstrual health being an especially neglected aspect of the gendered workplace experience. While menstrual health has gained increased attention over th
