- As the IAU heads towards its second century, many changes have simultaneously transformed Astronomy and the human condition world-wide. Amid the amazing recent discoveries of exoplanets, primeval galaxies, and gravitational radiation, the human condition on Earth has become blazingly interconnected, yet beset with ever-increasing problems of over-population, pollution, and never-ending wars. Fossil-fueled global climate change has begun to yield perilous consequences. And the displacement of people from war-torn nations has reached levels not seen since World War II. © International Astronomical Union 2020.

Prevalence of cannabis use among young adults in Sweden comparing randomized response technique with a traditional survey
- 2023
-
Ingår i: Addiction. - 0965-2140 .- 1360-0443. ; 118:9, s. 1801-1810
-
Tidskriftsartikel (refereegranskat)abstract
- Background and Aims: The prevalence of cannabis use based on self-reports is likely to be underestimated in population surveys, especially in contexts where its use is a criminal offence. Indirect survey methods ask sensitive questions ensuring that answers cannot be identified with an individual respondent, therefore potentially resulting in more reliable estimates. We aimed to measure whether the indirect survey method ‘randomized response technique’ (RRT) increased response rate and/or increased disclosure of cannabis use among young adults compared with a traditional survey.Design: We conducted two parallel nation-wide surveys during the spring and the summer of 2021. The first survey was a traditional questionnaire-based one (focusing on substance use and gambling). The second survey applied an indirect survey method known as ‘the cross-wise model’ to questions related to cannabis use. The two surveys employed identical procedures (e.g. invitations, reminders and wording of the questions)Setting and Participants: The participants were young adults (aged 18–29 years) living in Sweden. The traditional survey had 1200 respondents (56.9% women) and the indirect survey had 2951 respondents (53.6% women).Measurements: In both surveys, cannabis use was assessed according to three time-frames: life-time use; use during the past year; and use during the past 30 days.Findings: The estimated prevalence of cannabis use was two- to threefold higher on all measures when estimated using the indirect survey method compared with the traditional survey: use during life-time (43.2 versus 27.3%); during the past year (19.2 versus 10.4%); and during the past 30 days (13.2 versus 3.7%). The discrepancy was larger among males and individuals with an education shorter than 10 years, who were unemployed, and who were born in non-European countries.Conclusions: Indirect survey methods may provide more accurate estimates than traditional surveys on prevalence of self-reported cannabis use.

Numerical Simulation and Experimental Scheme for Monitoring Hoof Wall Structure and Health in Sport Horses
- 2016
-
Ingår i: Proceedings of the 4th International Congress on Sport Sciences Research and Technology Support. - : SCITEPRESS - Science and Technology Publications. - 9789897582059 ; , s. 171-175

Konferensbidrag (refereegranskat)abstract
- This study provides a computational model developed to demonstrate the possibility of monitoring hoof structure and health in equestrian sport. This is achieved by employing finite element simulation of threedimensional heat flow from a surface heat source into a hoof structure while simultaneously sensing the surface temperature. The time evolution of the recorded surface temperature, transient curve, is used to investigate hoof structure and predict its intactness by comparing these curves for three different models. We have observed differences between the transient curves obtained from a normal hoof structure, a hoof structure containing a foreign material and hoof capsule subjected to wall separation. An experimental method for probing hoof profile was briefly discussed. It uses temperature sensor/heat source. The method can determine the thermal conductivity of the hoof along the hoof structure from the recorded transient curve. Thus, it displays the hoof structure by utilizing the thermal conductivity variation between the hoof parts.

Bar-induced mass relocation in galactic discs
- 1999
-
Ingår i: Astronomy and Astrophysics. ; 344, s. 483-493
-
Tidskriftsartikel (refereegranskat)abstract
- The appearance of a bar in a galaxy considerably changes the mass distribution within the galactic disc. We have therefore performed a detailed study of the mass relocation within a stellar Kuzmin disc using two-dimensional numerical simulations with fixed 3D-potentials representing the bulge and the halo. We have started from a fully axisymmetric stellar distribution and followed the galaxy through bar formation and subsequent evolution. Once the bar has formed, the radial surface density profile will split up into three domains. The two innermost domains both have exponential profiles but with very different slopes. The outermost domain remain Kuzmin-like. Except for the very centre, the inner parts of the galaxy are depopulated out to a distance of approximately twice the length of the bar. The region just outside the bar experiences the most severe depopulation; in the presented simulation, the stellar density in this area falls to one-third its original value. All stars orbiting just outside the bar will be strongly perturbed on each orbit. Whether the star will be accelerated into a more eccentric orbit or decelerated into a less eccentric one depends on the position of the pericentre passage relative to the bar position. Circular orbits within this region are unstable. Stars from the region are thus spread out all over the disc. The stellar density in the outer parts of the galaxy thus increases. Depending on their original orbits, the stars will belong to either of two dynamical populations; stars originating in the outer parts will orbit on roughly circular orbits, while stars ejected by the bar from the inner parts of the disc will move on highly eccentric orbits. Stars can even be ejected into such extreme orbits that they escape from the galaxy. Barred galaxies can thus make a minor contribution to the population of intergalactic stars found in galaxy clusters without requiring near-collisions of galaxies.

Problems at the human-horse interface and prospects for smart textile solutions
- 2014
-
Ingår i: Journal of Veterinary Behavior: Clinical Applications and Research. - : Elsevier BV. - 1558-7878 .- 1878-7517. ; 9:1, s. 34-42

Tidskriftsartikel (refereegranskat)abstract
- The significant potential for so-called “smart textiles” in the design of the next generation of devices that measure pressure, tension, moisture, and heat at the humanehorse interface is discussed in this article. Research techniques from theoretical and experimental physics laboratories, combined with wireless technology, can be readily adapted to measure and store metrics for numerous variables in equine structure and function. Activities, such as breathing, the extension and flexion of joints, limb kinematics, and cardiac function, can be logged as indicators of physiological and behavioral conditioning (training). Such metrics may also, one day, support veterinary diagnostics but also play a role in safeguarding sporthorse welfare, especially in elite contexts where the horse may be pushed to its functional limits. As such, they are likely to emerge as an area of great interest to equitation and welfare scientists. It is important to note that smart textiles sense and react to exogenous stimuli via integrated sensors. So, beyond the equitation science laboratory, the emergence of polymers and smart materials may enhance the effectiveness of, or challenge us to completely rethink, traditional items of saddlery, thus improving equitation. The integration of smart textiles in all sorts of extant and emergent equipment for everyday equestrians could, in the future, lead to equipment that responds appropriately to the demands of equitation in its various forms. Rethinking equitation through physics and the use of smart textiles seems to have merit in that it is a novel means of both investigating and addressing problems that compromise the welfare and performance of horses. The purpose of this article is to envision the use of smart textiles in research, clinical, equestrian, and horse care contexts.

Finite element modeling of the Hot Disc method

Tidskriftsartikel (refereegranskat)abstract
- The Hot Disc method, also known as the transient plane source (TPS) technique, is an experimental approach to determine the thermal transport properties of materials. The core of the method is the Hot Disc sensor, an electrically conducting metallic strip, shaped as a double spiral clad with a protective polymer film. The mean temperature increase in the sensor has been approximated from various analytical approaches such as: the concentric ring sources model, the thermal quadrupoles formalism, and concentric circular strips structure approach. However, full numerical simulation of the sensor has not been addressed so far. Here we develop a 3D model of Hot Disc sensors and compare simulated mean temperature increase to experimental recordings. Joule heating coupled with heat transfer of solids (of COMSOL Multiphysics software) is used to simulate the working principle of the sensor. The volume mean temperature increase in the sensor from the simulations proves to be in a good agreement with the corresponding experimental recordings. The temperature distributions of the metallic strip are also evaluated and discussed with respect to the previous experimental findings. Furthermore, the current distribution across the strip is obtained. Such simulation can potentially be used in further optimizing geometry and parameter estimation.

SIMULATION OF THE HOT DISK SENSOR: TEMPERATURE AND ELECTRIC CURRENT DISTRIBUTION
- 2017

Ingår i: Proceedings of the Asian Conference on Thermal Sciences 2017.
-
Konferensbidrag (refereegranskat)abstract
- The Hot Disk method, also known as the transient plane source (TPS) technique, is an experimental approach for determining the thermal transport properties of materials. The core of the method is the Hot Disk sensor, an electrically conducting metallic foil (typically nickel), shaped as a double spiral, clad with a protective polymer film or mica. The double spiral serves simultaneously as heat source and temperature probe. The mean temperature increase of the TPS- sensor has been formulated from various analytical approaches such as: the concentric ring sources model, the thermal quadrupoles formalism, and concentric circular strips structure approach. However, full numerical simulation of the sensor has not been addressed so far. Here we develop 3D model of a Hot Disk sensor. The simulation provides information such as temperature and current distribution along each spiral which is not accessible from the experiment. Modeling feature, Joule heating coupled with heat transfer in solids of COMSOL Multiphysics software is used to simulate the sensor. The temperature and current distributions along the nickel wire is obtained. This can potentially be used in further optimizing geometry and estimating better parameters.

Thermal depth profiling of materials for defect detection using hot disk technique
- 2016
-
Ingår i: AIP Advances. - : AIP Publishing. - 2158-3226. ; 6:8
-
Tidskriftsartikel (refereegranskat)abstract
- A novel application of the hot disk transient plane source technique is described. The new application yields the thermal conductivity of materials as a function of the thermal penetration depth which opens up opportunities in nondestructive testing of inhomogeneous materials. The system uses the hot disk sensor placed on the material surface to create a time varying temperature field. The thermal conductivity is then deduced from temperature evolution of the sensor, whereas the probing depth (the distance the heat front advanced away from the source) is related to the product of measurement time and thermal diffusivity. The presence of inhomogeneity in the structure is manifested in thermal conductivity versus probing depth plot. Such a plot for homogeneous materials provides fairly constant value. The deviation from the homogeneous curve caused by defects in the structure is used for inhomogeneity detection. The size and location of the defect in the structure determines the sensitivity and possibility of detection. In addition, a complementary finite element numerical simulation through COMSOL Multiphysics is employed to solve the heat transfer equation. Temperature field profile of a model material is obtained from these simulations. The average rise in temperature of the heat source is calculated and used to demonstrate the effect of the presence of inhomogeneity in the system.

Konstnärligt arbete (övrigt vetenskapligt/konstnärligt)abstract
- The Ecoestrian jumping obstacle was a collaboration between four senior researchers; Maria Sundin (Senior Lecture at the department of Physics, University of Gothenburg), Angela Wulff (Professor at the Biological and Environmental Sciences, University of Gothenburg), Kristina Sundell (Professor at the Biological and Environmental Sciences, University of Gothenburg) and Ingrid Martins Holmberg (Senior Lecture at the Department of Conservation, University of Gothenburg), Arja Källbom (Building Conservator) and Carl-Johan Skogh (Senior Lecture in Design at the Department of design, Academy of Design and Crafts, University of Gothenburg). Thru the project leader Maria Sundin and her fellow partners, all with an interest in the field of equestrian culture, we got invited to participate in the Lövsta Future Challenge competition (www.lovstafuturechallange.se). The task was to develop and present a sustainable jumping obstacle that would be presented and used at the Gothenburg Horse Show 2017 (www.gothenburghorseshow.com). By mixing recycled material with new research of oyster based composite material and natural dying the design solution provided a new way of presenting and constructing jumping obstacle in a professional setting. The name “Ecoestrian” became as a word game between the words “ecologic” and “equestrian”. During 2017 the project has developed and was presented with a new design solution as “the Ecoestrian Herald” at the Longines FEI European Championship in Gothenburg.

Singlet Fission and Electron Injection from the Triplet Excited State in Diphenylisobenzofuran-Semiconductor Assemblies: Effects of Solvent Polarity and Driving Force

-
Ingår i: Journal of Physical Chemistry C. - : American Chemical Society (ACS). - 1932-7447 .- 1932-7455. ; 124:38 Josef Michl Festschrift, s. 20794-20805

Tidskriftsartikel (refereegranskat)abstract
- Singlet fission has emerged as a promising way to overcome the Shockley-Queisser limit in solar energy conversion devices, and a few studies have claimed proof-of-principle results using dye-sensitized photoelectrodes. However, a detailed understanding of what factors govern the fate of the excited state on mesoporous surfaces is still lacking. Here, we have studied how the excitation progresses into singlet fission, electron injection, or formation of molecular charge separated states in diphenylisobenzofuran derivatives with flexible carbon linkers attached to nanocrystalline mesoporous ZrO2, TiO2, and SnO2 thin films. We show that singlet fission occurs for the molecule attached to ZrO2 films when the assembly is immersed in nonpolar solvents, and that singlet fission is hampered by the formation of a molecular charge separated state in more polar solvents. On TiO2 surfaces, direct electron injection from the singlet excited state outcompetes the singlet fission. Instead, triplet formation occurs via charge recombination from the conduction band of TiO2 in nonpolar solvents. When the molecule is attached to SnO2 films, singlet fission partly outcompetes electron injection from the singlet excited state and the two processes occur in parallel. Subsequent to singlet fission on SnO2, triplet injection into the conduction band of SnO2 is observed. The results presented here provide a detailed picture of the singlet fission dynamics in molecules attached to mesoporous semiconductor surfaces, demonstrating that both the semiconductor substrate as well as the environment around the molecules have a large impact, which can be useful in the design of future devices.

Two-colour photoswitching in photoresponsive inorganic thin films
- 2021
-
Ingår i: Materials Advances. - : Royal Society of Chemistry (RSC). - 2633-5409. ; 2:7, s. 2328-2333

Tidskriftsartikel (refereegranskat)abstract
- Herein we report the first example of an inorganic photochromic material that allows for spatial addressability. We designed a photoresponsive thin film based on a ruthenium sulfoxide complex, [Ru(deeb)2PySO-iPr]2+, which was immobilized onto a mesoporous ZrO2 surface. The resulting material allows for all-optical detection and shows reversible, selective, photochromic behavior that can be cycled back and forth. The photosiomerization quantum yield is lower on the film than in solution which is attributed to a combination of the immobilization and steric hindrance by molecules in close proximity as evident from a surface coverage dependence of the photoisomerization quantum yield. The results reported here provide an important step towards inorganic photoswitchable materials.

- A non-invasive method for the detection of damage and changes in the hoof capsule Maria Sundin1, Magnus Karlsteen2,Andrey Sizov3, Björn Berg4, Arne Rosén1, Henrik Otterberg5, Åsa Hinton4, Mattias Gustavsson3 1: Dept. of Physics, University of Gothenburg) 2: Department of Applied Physics, Chalmers University of Technology 3: Hot Disk AB (Sweden) 4: Ale Animal Hospital 5: Hot Disk Medical AB (Sweden) Corresponding author: maria.sundin@physics.gu.se Horses may suffer from the presence of abscesses, cracks and keratomes in the hooves. This project is a feasibility study to investigate if existing material sensors can be used as a non-invasive, non-destructive method to help veterinaries/farriers getting a better knowledge of: 1.the exact location and extent of abscesses 2.the depth and length of cracks 3.the size of keratomes. The method is based on the ability of the hoof to conduct heat Utilizing the Hot Disk Sensors and method developed in ISO22007-2, with a novel computational procedure, the variations of thermal conductivity versus depth from a surface can be measured. Sub-surface structural variations can be monitored in a non-destructive manner. Applications can be found in a range of areas. For instance, verifying homogeneity of structure versus depth. The sensor, and its holder, has approximately the shape and size of a stethoscope. It is thus an object that a farrier/veterinary can handle with ease. An area of about one square inch of the hoof is heated 1-2 degrees with a single step-wise heat pulse. The thermal depth of probing follows a relationship: ?=2??, Where d represents the thermal depth of probing (from the sensor position into the hoof), a represents the weighted average of the thermal diffusivity of the hoof (from the surface position to the position d), and t represents test time. Hence, the depth position can be determined for the different time positions. A typical time for measuring to a depth of 10 mm in a hoof capsule is 160 seconds. So far, tests in laboratory environment have established that the existing equipment works on the material that a hoof capsule consists of. Tests have been done on hoof capsules from dead horses, 3D-printed model hooves and the hooves of one live horse at a veterinary clinic. All results are reproducible. Results show the curve of the thermal conductivity versus depth changing when the heat flow reaches a place where there is an inhomogeneity in the hoof. To conclude, tests indicate the method being able to detect inhomogeneities in hooves. Further measurements will be needed to show the exact response of different problems in the hooves. LP The method offers a possible new non-invasive, non-destructive method of finding the position and extent of abscesses, cracks and other inhomogeneities in hooves. The technique is well established in other areas of material studies, and based on the analysis of thermal convection and diffusion.

-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- One purpose of this paper is to share experience from astronomy education and outreach at the University of Gothenburg where concerns about artificial changes to our night sky are addressed today. For the moment the following courses include topics related to an altering appearance of the night sky: •The history of navigation •Ethnoastronomy •Space Exploration •Interstellar Communication •Astronomy and art Another purpose of this paper is to seek information and ask for help. All the courses above could be further developed. In the future, home assignments will be included as a part of the examination. All ideas about relevant questions connected to the protection of the dark and quiet skies are appreciated. Suggestions of tasks for the students to aid in spreading information regarding the state of the night sky to the community are welcome. There is usually a large interest from both students and the media concerning risks of impacts of satellites on the Earth as well as the risk of collisions between artificial objects in space. Included is a discussion of the important factors to raise in outreach or education concerning impacts, as well as questions about ethics, risks, awareness, psychology, and possible connections to the global goals. Most likely, a larger number of strange looking or moving objects in the night sky, will lead to an increase in questions to astronomers about what people have seen. How should we answer, and is this an opportunity to inform?

Magical Maps of Venus — Teaching the Geography of Venus
- 2023
-
Ingår i: Lunar and Planetary Science Conference 2023.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: One lecture was devoted to the ex-ploration and current knowledge about Venus in a course named Space Exploration during 2022 at the University of Gothenburg, Sweden. As part of the ex-amination, the students could choose to make their own maps of Venus. Most maps were faithful render-ings of the surface of Venus. A few were done with an unexpected level of creativity making them useful for outreach activities as well as teaching and learning. In this poster some of the maps are shown. The purpose is to show how it is possible to combine art and sci-ence, to inspire other teachers to do similar assign-ments and to discuss future possible pedagogical uses of the maps. Magical Maps: A few of the students choose to create maps in a style reflecting maps from ancient or more modern mythology. For example, one map was inspired by the maps of JRR Tolkien’s Middle Earth. Another map was created using Lego which adds the feature of 3D. A third map shows Venus as it would have looked with water and life. Maps as teaching tools: There is strong evidence supporting enhanced learning of students when com-bining text and illustrations, see e.g. [1]. Many people, perhaps especially children and young adults, are in-trigued by maps. This interest creates an excellent op-portunity for learning [2]. However, there are also stu-dents who are quite negative towards assignments where they sketch or draw. For the teacher, the chosen style of the map and the included features gives in-sights into the way the students think and learn. Vari-ous sources for the geography of Venus are available. Data could for instance be used from Magellan [3], Venus Express [4] or Google Venus. Maps in astronomy education: One of the aims of the poster is to discuss further use of maps in as-tronomy education. In what ways do we use maps when teaching astronomy? Why should the students make maps? How can we encourage students to cre-ate their own maps? How can we evaluate advantages of using maps in astronomy education?

Mars - a target for teachers and science students

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- A case study is here presented of an interdisciplinary course about Mars for teachers and science students. We aim to share the experience of creating an interdisciplinary approach with lecturers spanning physics, geology, radiation physics and philosophy. Issues in ethics, morality, rights and obligations, conflict management and human psychology as well as rocket orbits, fuel economy, radiation hazards and knowledge of the solar system have proven to be a valued and successful initiative for the further training of teachers and science students. The focus of the course is on planning for a journey with humans to the planet Mars. This provides a great opportunity to package complex societal problems in a physics context. The course is offered with a special sustainability content mark. Mankind has always had a strong and dependent relationship with the physical landscape. The land has given us food and shelter but also imposed challenges and disasters. Understanding the physical environment has been crucial for our survival and development. The same will be equally, or more important for Mars where life conditions are much more extreme. We highlight similarities and differences in the geologic processes that have shaped Earth and Mars. What conditions do the future explorers on Mars have to manage? We then enter the modern era and explore the dynamic Martian landscape of today. Also, by learning to read the landscape we may find locations of shelter such as vast systems of lava tubes, or locations of essential resources such as preserved glacial ice etc. A journey to Mars will cause substantially higher personal irradiation than obtained on Earth. The radiation part of the course lectures starts with defining the different radiation types and the biological effects these different types of radiation will cause. Then, the difference between the irradiation on Earth to the elevated irradiation in space and on Mars is described. Thereafter, it is discussed if this elevated radiation burden can cause acute biological effects, e.g. fatigue, vomiting and death, and late biological effects as cancer induction. Last, possible radiation protection strategies are described and discussed. The philosophy of space exploration consists of philosophical approaches to ethics, presently applied to the topic of Mars exploration and colonization, with environmental ethics (anthropocentric vs ecocentric) and value theory at its core. Four main uses of philosophy are distinguished: ethics, aesthetics, cognition and existentialism. Research has shown that visual representation is an important part for students to be able to create a deeper understanding of concepts as well as context about the material that is taught. Interdisciplinary and complex societal problems have also been shown to be important in science teaching. One way for the teacher to develop his/her teaching is to take further education courses in universities whose focus is to seek and discuss the complex societal problems as well as its solutions from a physics and teacher perspective. Future research could be done on the impact of this course on the education in different levels.

Konferensbidrag (refereegranskat)abstract
- An interdisciplinary course about Mars for teachers and science students is presented. The focus of the course is on planning for a journey with humans to the planet Mars. Issues in ethics, morality, rights and obligations, conflict management and human psychology as well as rocket orbits, fuel economy, radiation hazards and knowledge of the solar system are included. Examination of the teacher students include interpretation of the course material for future pedagogical usage.

- Sports in space? Is it at all possible to practice sports in our solar system but not on Planet Earth? Mars is our closest neighboring planet, and Titan is the largest moon of Saturn, and apart from the Earth it is the only body in our solar system where a liquid exists on the surface. Within the last ten years a system of lakes and rivers has been discovered. The climate and seasonal cycles of Titan are still not very well known, but the composition and pressure are fairly well established. Perhaps in the future boats will sail the lakes of Titan for research purposes or even sport. The purpose of this paper is to give an overview of the concept of space sports, looking at sailing on Titan and equestrian sports on Mars. For sailing, the conditions of Titan necessitate calculations of important parameters of sailing such as floatability, stability, hull resistance and sail forces. This paper shows that a sailing yacht on Titan will have twice as large displacement as on Earth and it will be 2.6 times less stable for the same beam. Since friction will be smaller, it will be faster than on Earth at low speed, but significantly slower at high speeds due to the wave generation. The same sail area is required to get the same sail forces if the average wind is 3 m/s, while a 9 times larger sail area is required if the wind speed is only 1 m/s. Equestrian sports on Mars could be a possibility, even if challenges exist in form of a cold climate and thin atmosphere with noxious gases. Due to the lower gravity sports such as show jumping, dressage and races would yield new records and new patterns of locomotion.
