The concept of industrial symbiosis (IS) provides practical solutions for resource efficiency and low-carbon development. The IS represents a collective, multi-industrial approach for companies to improve their economic and environmental performance through the sharing of heat, electricity, water, by-products, information, and reuse of waste. The main challenges to IS emergence include a long dura
The issue of pharmaceutical pollution has recently gained attention on the international political agenda as several actors have raised concern for its negative impact on ecosystems, human health, and livelihoods in emerging economies where an increasing share of the pharmaceutical production is located due to the cheaper labor and less stringent environmental regulations. In 2019, the OECD publis
Forced air convection systems are the most preferred design of choice in many of the industrial-scale convection ovens. In this study, experimental investigation on convective heat transfer and mass transfer within a forced air convection oven was performed at different oven temperatures (100℃, 110℃ and 120℃) and at flow velocity (2 m/s, 3 m/s and 4 m/s) using potato slices (10*10*60 mm) as model
In this thesis, a study is made into relative positioning and control systems for flying wing Micro Aerial Vehicles (MAVs) intended to be used by the Swedish Sea Rescue Society (SSRS) for the purpose of providing assistance during sea rescue missions. The particular scenario of interest is robust relative positioning to be used for autonomous landing of a MAV on a boat at the end of a rescue missi
The European Position Paper on Rhinosinusitis and Nasal Polyps 2012 is the update of similar evidence based position papers published in 2005 and 2007. The document contains chapters on definitions and classification, we now also propose definitions for 'difficult to treat' rhinosinusitis, control of disease and better definitions for rhinosinusitis in children. More emphasis is placed on the diag
This thesis aimed to search for etiological clues about cancer of unknown primary(CUP) by gathering novel information. The Swedish national registries were used and CUP cases were identified according to the seventh revision of the International Classification of Diseases. A consistent increase before the late 1990s and a dramatic decrease afterwards were observed for CUP incidence among Swedes,re
Infrared polarization spectroscopy (IRPS) was used to detect HCl in an 800 mm long tube furnace. Pieces of a polyvinyl chloride-carpet were continuously fed into the furnace producing a heavy smoke, which is exemplified by the fact that the smoke completely obscured a red laser beam from a He-Ne laser. This constitutes a very harsh environment from a diagnostic point of view due to the high smoke
Climate change poses a serious challenge to sustainable urban development worldwide. In Sweden, climate change work at the city level emerged in 1996 and has long had a focus on mitigating greenhouse gas emissions. City planners’ “adaptation turn” is recent and still ongoing. This paper presents a meta-evaluation of Swedish municipal adaptation approaches, and how they relate to institutional stru
Stochastic differential equations driven by standard Brownian motion(s) or Lévy processes are by far the most popular models in mathematical finance, but are also frequently used in engineering and science. A key feature of the class of models is that the parameters are easy to interpret for anyone working with ordinary differential equations, making connections between statistics and other scient
A study related to the development and characterization of a new gene delivery system was performed. The approach consists in both the pre-condensation of plasmid DNA with an arginine-based cationic surfactant, arginine-N-lauroyl amide dihydrochloride (ALA), which was found not to be toxic, and the incorporation of the blood protein transferrin (Tf) into the formulations.Two cationic liposome form
Objective. This study aimed to survey current Swedish practices for performing and handling transrectal ultrasound-guided prostate biopsies. Material and methods. A Swedish Urology Network (SUNe) was organized for the distribution of information, survey studies and research collaborations. A web-based questionnaire was distributed to the members in 2011. Results. In this first SUNe survey, 137 (91
We examined background information and course of labour from a cohort of 2,810 low-risk nulliparas to identify possible lifestyle and anthropometrical risk indicators for dystocia. Criteria for dystocia: cervical dilatation <2 cm over 4 h during labour's active phase, or no descent during 2 h (3 h with epidural) in the descending phase, or no progress for 1 h during the expulsive phase. After adju
The design and fabrication of a home-made thin-layer electrochemical flow cell are reported. The performance and electrochemical characteristics of thin-layer cells are evaluated in terms of flow rate and channel thickness. The adaptability of the flow cell for amperometric and electrochemiluminescence measurements is demonstrated. Also, a flow injection method comprising electrochemical generatio
The design, construction, and commissioning of the ALICE Time-Projection Chamber (TPC) is described. It is the main device for pattern recognition, tracking, and identification of charged particles in the ALICE experiment at the CERN LHC. The TPC is cylindrical in shape with a volume close to 90 m(3) and is operated in a 0.5T solenoidal magnetic field parallel to its axis. In this paper we describ
Purpose – This study has three broad objectives: (1) to explore consumer views on different dimensions of consumer packaging when it comes to a common staple food; (2) to discuss the role of different packaging features in consumer choice; (3) to compare consumer views on purchasing a common staple food either as an undifferentiated anonymous commodity or as a differentiated product.Design/methodo
We consider a moving-boundary problem associated with the fluid model for biofilm growth proposed by J. Dockery and I. Klapper, Finger formation in biofilm layers, SIAM J. Appl. Math. 62 (3) (2001) 853–869. Notions of classical, weak, and variational solutions for this problem are introduced. Classical solutions with radial symmetry are constructed, and estimates for their growth given. Using a we
Objectives The aim of this study was to investigate the association between the catechol-O-methyltransferase (COMT) 'pain sensitivity' haplotypes and chronic widespread pain (CWP) in two distinct cohorts. Methods Cases of CWP and controls free of pain were selected from two population-based studies: the Epidemiology of Functional Disorders study (EPIFUND) (UK) and the European Male Ageing Study (E
In this paper railway accident investigation reports issued by the national accident investigation boards in three Scandinavian countries during a 2-year period have been systematically studied. Content analysis of attributed causes in these reports reveals a considerable emphasis on physical processes, actor activities and equipment (the microlevel). Much less attention is paid to organisational
