In July 2021, single-use plastics will be banned from the European market, meaning that the plastic straws used with Tetra Pak’s portion packs will no longer be permitted. Therefore, Tetra Pak develops new straws, and it is important to test their functionality, something that previously has been done with panel tests. However, Tetra Pak has requested to aid the development process by minimizing t
Wastewater is an excellent source of nutrients and energy. By treating the wastewater in a clever way, it is possible to both recycle nutrients and recover energy, and thereby create opportunities for a sustainable system. In conventional wastewater treatment where the activated sludge process is used, aeration is needed and a lot of biomass is produced. In regions with warmer climate, or if low-v
Den biologiska mångfalden fortsätter att minska trots att det såväl nationellt som internationellt finns en målsättning om att förlusten av den biologiska mångfalden ska hejdas. Idag anses en av de största miljöpolitiska utmaningarna vara att stoppa utarmningen av biologisk mångfald. Skogen utgör livsmiljö för hälften av alla landlevande arter i Sverige och ett hållbart skogsbruk är således livsavBiodiversity is in decline despite international and national goals of preventing this development. Preserving biodiversity is one of today’s greatest environmental policy challenges. Currently, half of all land living species in Sweden live in the forest, therefore a sustainable forestry industry is vital to ensure biodiversity. In fact, half of all red-listed species live in the forest. One of t
Den ökade användningen av läkemedel och otillräcklig teknik i reningsverken har lett till allt större halter av läkemedel och andra organiska mikroföroreningar (OMF) i naturliga vatten. Detta har i sin tur konstaterats påverka exempelvis fiskars beteende och fortplantningsförmåga. OMF har även detekterats i det svenska dricksvattnet. På grund av detta har en satsning skett de senaste åren inom forThe increased use of pharmaceuticals in combination with inadequate techniques and procedures in the wastewater treatment plants (WWTPs) have resulted in higher concentrations of pharmaceuticals and other organic micro pollutants (OMPs) in the aquatic environment. It has been established that these pollutants have caused changes in the behaviour and reproduction of fishes. Furthermore, these OMPs
In 1994 the Swedish Construction Code, BKR, was changed from being based on material to being based on function. This permitted constructing multi-storey buildings with a bearing framework made of wood, which had been prohibited since the end of the 19th century. There is now a growing in- terest of using wood as a construction material. In Växjö four seven-storey buildings, Limnologen, are under
The idea of energy efficient, healthy buildings has existed since 1970s. However, a one-dimensional approach for many housing issues does not assure sustainability. Therefore, near the end of the 20th century, the built environment became a focus of attention within the environmental movement with wider focus on building certification schemes and sustainability issues such as interrelationships be
Backgrund: Nederman har ett långsiktigt mål att förbättra enheten i Helsingborg. Ett steg i detta är att se om det finns några förbättringar att genomföra i lagerstyrningen i form av lager- och servicenivåer. Detta då de anställda upplever dagens verktyg som ganska trubbiga för det nuvarande produktsortimenetet och att detta kanske kan förbättras genom ytterliggare en dimension på det befintliga s
Purpose: The aim of this study was to investigate if the inverse planning available in the dedicated planning program VariSeed 7.1, can generate plans of equal quality to plans generated through manual planning.Materials and Methods: In this study the dedicated permanent seed implantation planning system VariSeed 7.1. (Varian, Paolo Alto California) was used for inverse planning, using a dose-volu

Lina Magnusson disputerade i november med en avhandling om ortopedteknisk service i utvecklingsländer. Lina Magnusson är den första kvinnliga ortopedingenjören som disputerar i Sverige. Hennes avhandling beskriver patienters rAim: The overall aim of this thesis was to generate further knowledge about prosthetic and orthotic services in developing countries. In particular, the thesis focused on patient mobility and satisfaction with prosthetic and orthotic devices, satisfaction with service delivery, and the views of staff regarding clinical practice and education. Methods: Questionnaires, including QUEST 2.0, were use
Popular Abstract in Swedish Studier av arbetsförhållande inom sjukvården har under lång tid varit förknippade med stress och sjukfrånvaro. Ett sådant problemorienterat perspektiv hänger samman med hälsa definierat som avsaknad av sjukdom (patogenes). Hälsa kan dock definieras på många olika sätt och motsatsen till patogenes är salutogenes. Ett salutogent perspektiv innebär en mer positiv syn på häThe aim was to explore and make sense of a salutogenic relationship between workplace, work and health, through an employee perspective in a Swedish nursing context. The aim was also to make sense of the role of a workplace health promotion (WHP) process, in a salutogenic public health perspective, and develop useful instruments for this kind of health-related development work. The research proces
Accelerated pavement wear is one of the major environmental disadvantages of studded tyres in northern regions and results in increased levels of PM10. Measurements of PM10 in a road simulator hall have been used to study the influence of pavement properties, tyre type and vehicle speed on pavement wear. The test set-up included three different pavements (one granite and two quartzite with differe
Popular Abstract in Swedish Att fortsätta leva på mitt sätt. Medelålders kvinnor och menopaus/klimakteriet. Varje år passerar cirka 65 000 svenska kvinnor sin menopaus. Menopaus är en medicinsk term och avser tidpunkten för en kvinnas sista menstruation. Tidpunkten för menopaus kan därför i regel endast avgöras i efterhand, vanligtvis först efter ett års uppehåll av de naturliga menstruationernaTo deepen the understanding of menopause and its role in women's lives is the general aim of this thesis. Between 1995 and 2003, all women in two Swedish primary health care districts received a postal questionnaire, when they were 45, 50, 55 or 60. A total of 1681 women (76%) responded. Twenty-four women were given research interviews. The effects of menopause on quality of life (QoL) and number
Developmental and comparative studies of the ability to understand communicative intentions using object-choice tasks raise questions concerning the semiotic properties of the communicative signals, and the roles of rearing histories, language and familiarity. We adapted a study by Tomasello, Call, and Gluckman (1997), in which a “helper” indicated the location of a hidden reward to children of th
Pure rotational coherent anti-Stokes Raman scattering (CARS) experiments have been performed in acetylene for temperatures ranging from 294 to 582 K, and in mixtures of acetylene and nitrogen in the mole fraction range of 0.06-0.32 for acetylene at room temperature. The experimental spectra are evaluated by a least-square fitting to libraries of theoretically calculated spectra using two different
Min avhandling handlar om hur barns medfödda temperamentsegenskaper påverkar deras risktagande. Temperamentsegenskaper antas avspegla aktiviteten i biologiskt nedärvda motivationssystem. Aktiviteten i dessa avgör hur snabbt, hur starkt och hur länge vi kommer att reagera i olika situationer. I vår första studie ville vi studera psykometriska egenskaper hos det frågeformulär vi avsåg att använda i This thesis concerns temperamental qualities and their influence on risk-taking behavior during middle childhood (7–11 years of age). Contemporary research generally agrees upon the notion that temperament constitutes two motivational systems, sensitive to punishment and reward respectively, together with a third system that is responsible for regulating the motivational systems. Risk-taking is ge
Anticoagulant treatment of acute pulmonary embolism (PE) has traditionally been hospital-based. The lesser need for monitoring with the increasingly used direct acting oral anticoagulants (DOAC) in comparison to warfarin potentially facilitates outpatient treatment of PE with these drugs. This study aimed to evaluate efficacy and safety of outpatient treatment of PE with DOAC. We extracted data fr
The aim of this study was to explore how primary care social workers discuss their professional role and discretion in relation to considerations of sick leave for patients with mental illness, thereby deepening the understanding for how consultation and informal decision processes manifest between social workers and doctors working within the same organisation.

IKEA, a company well known around the world for their furniture, is also keen on using digital solutions to improve the customer experience. One of these solutions is the self-serving kiosk, a 27" touchscreen, that helps the customers find and buy products. As many other companies of similar size, IKEA wants to use the data from their digital solutions, as a base for some of their decision ma
Problem definition: The increasingly informed customer will lead to an even greater demand for expertise and knowledge of marketers. Firms need to find new ways to utilize the informed customer as a co-creator of value by more proficiently analyzing behavior, both online and offline. An uncertainty lies in to which extent the operational standards of KIBS firms translate to their marketing and sal
