Abstract [en]

This study explores how participants suffering from stress-related mental disorders describe their perception, interaction, and lived experience of garden smellscape during their nature-based rehabilitation. Natural elements, and especially nature smells, have been found to have a profound effect on stress reduction, suggesting an interesting link between odor in nature and stress reduction. The study was conducted as a longitudinal case-study, running over a period of 5 years, investigating participants’ perceptions of a garden smellscape, after completing a 12-weeks nature-based rehabilitation in Alnarp Rehabilitation Garden, Sweden. All participants were treated for stress-related mental disorders. Data were collected through retrospective semi-structured individual interviews and analyzed according to interpretative phenomenological analysis. The results revealed in what way nature odor (odor in nature) evoked associations, emotions, and physical reactions and provide examples of how nature scents function as a catalyst for sensory awareness and memories. Findings supported the understanding that experiencing the smell of plants, especially pelargonium, may facilitate stress reduction and support mental recovery in a real-life context. The results of the study can be used for several purposes; thus, they are relevant for actors within the development of nature-based therapy, as well as stakeholders within the horticultural industry.

Abstract [en]

Purpose – This paper aims to unveil how sustainability is integrated into the courses/programmes ofhigher education institutions. The research question addressed is: how do academics representing differentdisciplines cooperate and engage in the work of integrating sustainability into their teaching programmes.Design/methodology/approach – This paper draws upon the notions of practise variation andinstitutional work from institutional theory and empirically focusses on the case of Kristianstad University(Sweden). This case is based on an autoethnographic approach and illustrates the experiences shared by sixcolleagues, representing different disciplines, engaged in implementing sustainability in their courses/programmes.Findings – The findings highlight how academics representing different disciplines, with specific traditionsand characteristics, face the sustainability challenge. Despite being bound by similar sustainable developmentgoals, differences across disciplines need to be acknowledged and used as an asset if trans-disciplinarity is theultimate goal.Research limitations/implications – Although the intrinsic motivation of individuals to work withsustainability might be a strong driver, the implementation of sustainability within courses/programmes andacross disciplines requires joint efforts and collective institutional work.Practical implications – By highlighting how academics engage in the work of integratingsustainability, this study emphasizes that managers of higher education institutions need to account for thetime and additional resources needed to ensure that academics effectively cope with sustainability. Intrinsicmotivation may not last if organizational structures and leadership are not supportive on a practical level andin the long run.

Abstract [en]

To increase the acceptability of insects as food in Western culture, it is essential to developattractive, high-quality food products. Higher acceptability of insect-based food has been shown ifthe insects are “invisible”. Mincing or chopping the insect material could be a first processing stepto reduce the visibility of the insects. In this work, we processed yellow mealworms by usingtraditional food techniques: chopping, mixing and heat treatment in a retort. The results show thatall factors in the experimental design (particle size, oil content, salt content and antioxidant)influenced the products to a larger extent than the storage time. The results, measured by sensoryanalysis, TBAR values (Thiobarbituric acid reactive substances), colourimetry and viscosity, showclearly that the food products packaged in TRC (Tetra recart cartons) 200 packages and processedin a retort stayed stable during a storage time of 6 months at room temperature.

Abstract [en]

The nutrient load and export of nutrients from the lake "Arkelstorpsviken" in southern Sweden were monitored for one year (2019-04-01 to 2020-03-31). The purpose was to study whether the lake's eutrophication status is a symptom of internal load or caused by the load from the environment. The results can be used in a remediation plan for the heavily eutrophied lake Arkelstorpsviken, where extensive monitoring was carried out. Sampling stations in the main three upstream streams were set up to record the daily flow, supplemented by a 14-day sampling period for chemical analysis. In addition, small agricultural ditches and the local municipal treatment plant were monitored. Both total phosphorus and total nitrogen were reduced during transit through the lake. This indicates that the lake still acts as a nutrient sink contrary to the prevailing suspicion that the sediments are leaking phosphorus.

Abstract [en]

It is well known that tap water tastes different due to where the water is tapped, ie its chemical and microbiological compositions. Taste competitions have been performed in different countries to find out the most preferred tap water. With some few exceptions, no studies have been performed in which the taste of tap water is objectively described by analytical sensory methods. The purpose of this study was to evaluate quality of Swedish drinking water from different dwells with emphasis on sensory, chemical and microbiological analyses.

 

Tap water origin from surface water and from groundwater was collected from the Swedish municipalities Svalöv and Kristianstad. The water samples were collected in 3 points in each municipality: 1. waterworks; 2. near waterworks; 3. far from waterworks. In addition the commercial water Evian was included in the analyses. Analytical sensory analyses (triangle test and quantitative descriptive analysis) were performed along with chemical and microbiological standard analyses according to Swedish drinking water standards.

 

The results from the triangle test showed significant sensory differences between tap water from surface water and groundwater, as well as in surface water samples collected in different points. The descriptive analysis showed large differences in the perception of bitterness, minerals and off flavours. The perceived differences are in line with earlier studies pointing out inorganic ions as responsible for the taste sensations. The chemical analyses showed that the major difference between the two types of tap water was a higher mineral content and higher alkalinity in the groundwater compared to the surface water. The microbiological analyses did not show any measurable concentrations in any of the samples. There is a need for further research of chemical and microbiological effects on the flavour of tap water, with focus on microorganisms and chemical compounds in low concentrations.

Abstract [en]

In the present study, two combinations of filter materials in filter/columns were examined for removal of total organic carbon (TOC) and polyphenols (PP) found in storm water runoff from wood storage areas in a wooden floor industry. One filter/column was packed with peat mixed with carbon-containing fly ash, while another filter/column contained only peat (without ash). The mixture of peat and ash has shown faster and higher removal capacity for TOC and faster removal with the same final removal capacity for PP (in grams of pollutant per kg of sorbent) at the saturation point. The superiority observed for the peat and ash filter is presumably due to the unique characteristics of peat and ash, which enhanced the treatment efficiency when used together in a mixture. Based on the observed results, filters formed by peat and carbon-containing ashes proved to be a potentially low-cost option for the treatment of storm water generated at storage areas of wood materials such as logs, sawdust and wood chips.
