description: Metastatic estrogen receptor-positive (ER+) breast cancer causes the death of more women than any other type of breast cancer annually. Positron emission tomography (PET) is used to stage cancer metastasis, assess treatment strategies, and monitor the effects of therapy with appropriate radiotracers. 18F-fluoroestradiol (18F-FES) has been used for PET imaging to detect ER+ breast cancer. However, imaging of ER+ tumors with 18F-FES is associated with diverse challenges such as off-target uptake, extensive metabolism, and imaging of soft tissue tumors. Developing the new 18F-tracers for ER+ breast cancer imaging is an underlying need. A novel 18F PET tracer can detect, occurrence and recurrence of ER+ breast cancer with a high-resolution image that will define treatment strategies for breast cancer patients. My dissertation (chapter 1) discusses the strategy, methods, and challenges of late-stage radiofluorination[18F] for the development of new 18F PET tracers. Reductive elimination from diaryliodonium salt is one of the used methods for [18F]-labeling of drug and bioactive molecules. The iodine-mediated [18F]-labeling method has promises and challenges. An ideal novel, efficient and robust radiofluorination method would allow synthesizing a wide range of 18F-labeled drug molecules. In this work, we develop aryl fluorination and radiofluorination methods by regioselective reductive elimination from tetraarylbismuth(V) compounds. As a part of the radiofluorination method development, tri- and/or tetraarylbismuth(V) radiofluorination precursors were synthesized, and selective fluorination of the aryl ligands by a nucleophilic 19F-fluoride source was studied. Chapters 2 & 3 discuss the progress of developing a novel method for 18F-labeling of drugs and bioactive molecules by reductive elimination from bismuth(V) compounds.

description: In response to rainfall, highway surface runoff discharges may contain pollutants that have accumulated on the carriageway, particularly following periods of dry weather. In the UK the Highways Agency, in association with the Environment Agency, commissioned a 5-year study in 1997 to collect data to improve the understanding of contaminants in highway runoff and the treatment efficiency of drainage systems. The study involved the instrumentation and monitoring of non-urban highway surface water drainage and the receiving water at 6 sites for a minimum of 1 year. Highway runoff and receiving water samples were analysed for up to 40 determinands. The results have been used to identify ranges of pollutant concentrations in highway runoff; relationships between runoff concentrations/loads and both highway and environmental factors; drainage system treatment efficiencies; and, impacts on receiving waters. The greatest observed pollution removal efficiency was produced by a combination of a bypass oil separator and surface flow wetland-wet pond. The paper describes the methods used for runoff monitoring and the results from the initial study at 6 sites, focusing on the efficiency of a number of drainage system types and drainage features. Assessment of treatment efficiency indicates that there is a wide range of pollution removal efficiencies for the individual and combinations of treatment devices at the monitored sites.

description: A large experimental study on 8 different building materials is going on in collaboration with VTT and TTY, Finland. These materials are tested as pure materials and as a part of building envelope constructions both in laboratory and outdoors. The laboratory tests are made partly under constant, but different conditions, and partly under varying conditions to simulate the effect of fluctuated wet, dry and frost periods.  In the field exposures outdoors, the materials and constructions are tested under real conditions.

The main aim of this experimental programme is to use the measured results in developing of an improved model to predict mould growth. This improved model is based on an existing mathematical model developed on wood at VTT during 1990's. The focus in this new model is to extend the use for other materials, too, and also for a greater variety of conditions.

This paper presents how the existing model is improved and also discusses the whole problem of modelling such a phenomenon. A sensitivity analysis of modelled mould growth and comparison with measured mould growth are also presented.  The experimental set-ups and the results since 2005 from these extensive measurements on many different materials are presented more detailed in another paper to this conference.

description: Air flow through horizontal openings is an important issue of mass and energy transfer between different zones in buildings. Horizontal openings occur in staircases, stairwells, ventilation shafts, service shafts and chimneys and so mass and energy transfer through them have important implications regarding energy saving, thermal comfort, control of contaminants and micro-organisms and spread of fire and smoke. Air flow through vertical openings has been widely researched but little information is available regarding flow in horizontal openings,
This paper describes a detailed experimental study of the phenomenon of buoyancy driven natural ventilation through single-sided horizontal openings. The experimental analysis was carried out in a full-scale laboratory test rig and the basic nature of air flow through the single-sided openings was investigated.  The research is focused on obtaining knowledge of the air flow rate through the horizontal openings driven by buoyancy. The bi-directional air flow rate was measured using constant injection tracer gas technique. The variable parameters included temperature difference between the rooms and the size of the horizontal opening. The measurements were made for opening ratios L/D in the range of 0.115 to 4.445, where L and D are the length of the opening and the diameter of the opening, respectively.
Smoke visualization showed that the flow patterns are highly transient and unstable, and the air flow rates oscillate with time. The air flow rate can be obtained by a correlation between Froude number Fr (dimensionless air flow rate) and L/D ratio. A comparison of the dimensionless air flow rate Froude number Fr versus L/D curve between the measurements and Epstein formula indicates that   the experimental data has a similar tendency as the Epstein formula. However, significant differences existed for L/D range less than 0.15 and from 0.4 to 1.0 resulting in much higher air flow rates.

description: The main objective of the research project described in this paper was to study the potential for reducing energy used for ventilating buildings by using low-polluting building materials, without compromising the indoor air quality. To quantify this potential, the exposure-response relationships, i.e. the relationships between ventilation rate and perceived indoor air quality, were established for rooms furnished with different categories of polluting materials and the simulations of energy used for ventilation were carried out. The results suggest that the exposure-response relationships vary between different building materials and that the perceived air quality can be improved considerably when polluting building materials are substituted with materials that pollute less. The energy simulations indicate that selecting low-polluting materials will result in considerable energy savings as a result of reducing the ventilation rates required to achieve acceptable indoor air quality.

description: Hypothesis and Objective: Clinically perceptible color differences are observed when titanium or gold-hue titanium abutment materials are used with high-translucency zirconia. The objective of this study was to evaluate the effectiveness of an opaque medium painted on high translucency monolithic zirconia in masking the underlying implant abutment material. Our null hypothesis is that there is no mean difference in the color difference value (ΔE00) for each abutment material group between the opaqued and non-opaqued groups. Methods: Zirconia, titanium, and gold-hue titanium discs were fabricated to emulate abutment materials (N=10). Telio discs were used as control group. E.max ZirCAD MT discs were used to emulate high translucency zirconia restorations. Half of the E.max ZirCAD MT discs were painted with an opaque medium. The different groups were cemented with either SpeedCem Plus transparent or opaque-shade cement. A calibrated reflectance spectrophotometer was used to measure color parameters for each of the samples (L*a*b* values of CIE L*a*b* color space). The ΔE00 was measured between the control group and test groups. The effect of an opaque medium, implant abutment material and luting cement on the color of high translucency zirconia was analyzed via a Two-way ANOVA. Results: There was a statistically significant mean difference between opaqued and non-opaqued samples on the color of high translucency zirconia for titanium and gold-hue-titanium abutments, p-values are < 0.001 and 0.045, respectively. However, there was no statistical difference between opaque and non-opaque when zirconia abutments were used, p-value = 0.254. With an opaque layer, luting cement color did not have a statistically significant effect on the color of high translucency zirconia in comparison to non-opaqued zirconia. Conclusions: An opaque layer improves the color match for all abutment materials in comparison to no opaque layer; however, titanium and gold-hue titanium abutments still result in a clinically unacceptable result.

description: We present a Crawl-space heating with thermal storage. It is a heating system using the crawl space of foundation-insulated houses with no underground room as a duct for heat transport and as a space for installing the thermal storage equipment. We used a heat pump as a heat source and sensible thermal storage materials for heat storage. The thermal storage equipment is charged by the heat pump by using cheap off-peak electricity and it is discharged into the crawl space at daytime. We conducted experimental studies and it is revealed that thermal behavior of the room is greatly influenced by the quantity of charged and discharged heat and the change of the room temperature can be made moderate by increase the quantity of the stored heat.
Development of a Rubric to Evaluate Implementation Quality of Simulation-based Courses: A Consensus Study

Year: 2022
Subjects: Uncategorized

description: A. Background When simulation-based courses fail, there are at least two reasons: the content and structure were inadequate, or the quality of the implementation process was faulty. Evidence-based, stepwise approaches to ensure the development, delivery, and evaluation of simulation-based courses are well-established. However, best practices for implementation of these courses based on implementation science, are not widely known, or applied. The purpose of this study was to employ consensus building methodology to define content for a rubric, Implementation Quality Rubric for Simulation (IQR-SIM), to evaluate the implementation quality of simulation-based courses in health professions education. B. Methods A three-round, modified Delphi process involving international simulation and implementation experts was initiated to gather and converge opinions regarding criteria for evaluating the implementation quality of simulation-based courses. Candidate items for round 1 were developed based on the Adapted Implementation Model for Simulation (AIM-SIM). The items were revised and expanded to include descriptive anchors for evaluation in round 2. The criterion for inclusion was 70% of respondents selecting an importance rating of 4 or 5/5. Round 3 provided refinement and final approval of the content and descriptive anchors. C. Results Thirty-three experts from 9 countries participated. The initial rubric of 32 items was reduced to 18 items after three Delphi rounds, resulting in the IQR-SIM: a three-point rating scale, with non-scored options “Don’t know/can’t assess” and “Not applicable”, and a comment section. D. Conclusion The IQR-SIM is an operational tool that can be used to evaluate the implementation quality of simulation-based courses and aid in the implementation process to identify gaps, monitor the process, and promote the achievement of desired implementation and learning outcomes.

Simulation of a passive, climate controlling façade.

Publisher: name: 8th Symposium on Building Physics in the Nordic Countries

description: A new façade concept is being developed that aims to reduce the primary energy consumption of climate installations by making use of changes in both indoor and outdoor climate. Unlike other facades, this Climate Adaptive Skin utilises mostly passive technologies to create a comfortable indoor environment all year round. To determine the potential of the new façade design, its performance is being simulated using The Mathworks program ‘Simulink’.
The façade utilises technologies that are already available, but not commonly used within this context. To be able to use both daytime and night time temperatures, the façade is equipped with a stack of PCM plates that is able to buffer thermal energy: in summer, cool night temperatures are used to cool the indoor environment during the day, while in winter the PCM can be heated using cheap night time electricity to heat the office during the day. To reduce the amount of energy required to heat the PCM, the façade is equipped with an air-to-air heat exchanger that uses the waste heat from exhaust air to preheat incoming ventilation air when needed. The risk of overheating in summer is reduced by using thermotropic glass that changes from transparent to translucent white above a certain threshold temperature. Once white, the glass reflects a large part of the incoming solar radiation, while still transmits diffuse light, reducing the need for artificial lighting.
Simulations indicate that it is possible to keep the indoor temperature within comfortable temperature limits throughout the year using climate data from 1995 which had a very warm summer. Only during a few days in mid summer the indoor temperature becomes too high for comfort because the outdoor temperature does not get below 19°C, not even at night, preventing the PCM to shed unwanted heat during the night and preventing form cooling down. Additional research using simulations and prototypes will improve the concept design.

description: Internet of Things is an ecosystem of interconnected devices that are accessible through the internet. The recent research focuses on adding more smartness and intelligence to these edge devices. This makes them susceptible to various kinds of security threats. These edge devices rely on cryptographic techniques to encrypt the pre-processed data collected from the sensors deployed in the field. In this regard, block cipher has been one of the most reliable options through which data security is accomplished. The strength of block encryption algorithms against different attacks is dependent on its nonlinear primitive which is called Substitution Boxes. For the design of S-boxes mainly algebraic and chaos-based techniques are used but researchers also found various weaknesses in these techniques. On the other side, literature endorse the true random numbers for information security due to the reason that, true random numbers are purely non-deterministic. In this paper firstly a natural dynamical phenomenon is utilized for the generation of true random numbers based S-boxes. Secondly, a systematic literature review was conducted to know which metaheuristic optimization technique is highly adopted in the current decade for the optimization of S-boxes. Based on the outcome of Systematic Literature Review (SLR), genetic algorithm is chosen for the optimization of s-boxes. The results of our method validate that the proposed dynamic S-boxes are effective for the block ciphers. Moreover, our results showed that the proposed substitution boxes achieve better

description: In 2005 a low-energy building was inaugurated in Sisimiut, Greenland, just 50 km north of the Arctic Circle. The 200 m2 building was supposed to be a building with an energy consumption for heating of only half of the maximum permissible according to requirements of new Greenlandic Building Regulations. Thus, the target heating consumption was set to 80 kWh/(m2∙year).
The low energy feature was accomplished by using well insulated structures without cold bridges, a ventilation system with heat recovery, advanced windows and a solar heating system. In addition, it was an ambition that the indoor climate should be comfortable and healthy, and the highly insulated structures should remain free from moisture problems.
Since its invention the building has functioned, in one half, as residence of a Greenlandic family, and as an exhibition in the other half. The building has been instrumented with sensors and a data logging system that measure the energy performance of the various parts of the system, and sensors for detection of moisture conditions in the building envelope and in the indoor environment. The energy performance data can be followed on the Internet on a day to day basis.
The paper will present the house and the experiences from the first two years of its operation. An account will be given of the measured energy performance data. Some of the equipment did not function completely as anticipated, but some corrective measures are described, and the most significant challenges are discussed.
Self-regulating hydronic floor heating systems in low energy buildings

description: The awareness in society concerning environmental impacts due to the energy consumption in buildings is steadily growing. As a result, the general demand for buildings with low environmental impact, and especially the energy consumption, is very likely to increase even more in the future. Today’s building concepts will probably not be consistent with future demands for energy efficient buildings with an optimal indoor environment. Buildings with significantly lower energy demands for space heating can be achieved by different means. However, in the Nordic climate there is still a resultant need for additional space heating to ensure an optimal thermal indoor environment. Today, hydronic floor heating is by far the most common heat supply system for space heating in new residential buildings in the Nordic region. A building design concept based upon a building with a low heat demand, which is supplied by a hydronic floor heating system, is considered in this paper. The water temperature supplied to the floor heating system is only a few degrees above the desired room temperature. A low supply temperature offers an ultimate flexibility when the primary heat source is selected. Furthermore, in comparison with today’s floor heating systems, the low temperature system will more or less be self-regulated due to the small temperature difference between floor surface and indoor air. The process of self-regulation is a highly dynamic thermal process. A state-of-the-art numerical simulation model is applied to study this process. Especially the temperature fluctuations in the indoor operative temperature will be studied. Furthermore, a tepid floor construction, due to the operation of the floor heating system, will decrease the ability to react on internal heat loads, a reduction of the buildings heat capacity occurs. This phenomenon is also studied in this paper by means of the simulation tool.

Battery Material Characterization Using On-Chip Electrochemical Platforms

description: One dimensional nanomaterials offer unique physical phenomena and improved physical properties, which have the potential to benefit diverse societal applications. Harnessing these benefits require developing both material synthesis processes as well as characterization methods to better understand their performance. To overcome the challenge of nanomaterial characterization at the single particle level, this dissertation employed a unique on-chip platform and dielectrophoretic nano assembly techniques to isolate single nanomaterials for further study and investigation. This facilitated characterization of battery relevant materials at the individual level for their responses to mechanical action and electrochemical reaction. Silicon-Germanium (SiGe) and manganese dioxide (MnO2) nanowires were chosen as representative battery electrode materials to be tested for their nanomechanical behavior. Although being ceramic materials, structural defects were revealed to cause plastic deformation and recovery in these materials at the nanoscopic size regimes as opposed to the brittle behavior observed in their macroscopic counterparts. In case of SiGe, a high surface defect density and nanotwin boundaries caused plastic deformation and recovery through dislocation movement and annihilation, respectively. On the other hand, MnO2 crystal structure is a mixture of heteroscopically sized grains, which get activated under external load and go through reversible phase transformation. These findings were courtesy of AFM based three-point bending test methodology, which also revealed loading rate dependent ductile to brittle transition and discussed loading orientation with reference to the crystal. The MnO2 crystal is made of network of MnO6 octahedra and has rectangular tunnels suitable for ionic conduction. This material was investigated for insertion of Li and Mg ions, two candidates for the battery electrochemistry. Li insertion shows reversible intercalation below 1.0 Li per Mn limit, over which it initiates conversion reaction. On the other hand, Mg ion readily converts the host material irreversibly to an alloy phase at 0.5 Mg per Mn. These conclusions were made from electron microscope imaging and spectroscopy. Moreover, this method addresses the challenge of limited radial diffusion associated with in-situ TEM electrochemistry set-ups and allows for radial ionic diffusion in electrode materials thereby, mimicking their real-life operation.

description: Damages, caused by moisture and mould, in attics have increased in Sweden during the last decades. The main reasons are thicker thermal insulation between the living space and the attic and lack of the heat and ventilation effects from a warm chimney. Cold attics are ventilated to avoid that heat leakage from the living space heats up the outer roof with snow melting and icicles as result. Using traditional ventilation the climate in the well insulated attic becomes close to the outside climate. The original main purpose of the ventilation is therewith not valid any more. There can be other reasons to ventilate the attic, for example to take away the humid air that can be transported to the attic from the living space trough diffusion and moisture convection.  Also water from small and occasional water leakage can be removed from the attic by the ventilation.

There can also be disadvantages with ventilation. The wind pressure against the building can sometimes course a under pressure in the attic, which increases the moisture convection from the living space into the attic. During clear cold nights the heat radiation from the roof into the sky could lead to that the temperature at the inner side of the roof gets lower than outside, which increases the risk for condensation.

This paper presents the results from a project where a newly developed commercial vapour retarder has been used to achieve a dryer climate in a highly insulated cold attic. Field measurements during two years are presented and comparisons with other measures two achieve a dryer climate in highly insulated cold attic are given.

description: ABSTRACT Today, many sewer systems are monitored closely with on-line data with high resolution in time. This information is used to plan and optimize the management of the system by checking pump performance, counting the number and size of combined sewer overflows etcetera. Sometimes the data is also used to calibrate hydrodynamic models of the sewer system. However, the information can also be used to study long-term changes in the performance of the sewer system and to identify sources of water not belonging to the sewer system. The paper discusses what types of runoff can be assessed based on different types of measurements, ranging from pumping stations with daily readings of pumping time to several years of accurate flow measurements distributed throughout the sewer system. The sources are divided into four identifiable sources: sewage, slow infiltration, paved runoff, and fast infiltration. The objective is to identify these sources based on time series of one flow gauge and on rain information. The pros and cons of four approaches are discussed and the methods are applied to a case study. With care, the simple spreadsheet calculation approach yields similar results as the more comprehensive methods. However, the result is to some extend based on judgment and skilled interpretation of the actual processes taking place. The more comprehensive methods do also provide more information by means of model parameters useful for the interpretation

description: Approximately one third of all epilepsy patients are resistant to current therapeutic treatments. For those with drug resistant epilepsy, some patients with focal forms of epilepsy benefit from invasive surgical approaches that can lead to large surgical resections of human epileptic neocortex. We have developed a systems biology approach to take full advantage of these resections and the brain tissues they generate as a means to understand underlying mechanisms of neocortical epilepsy and to identify novel biomarkers and therapeutic targets. Additionally, this highly characterized data and tissue bank has given us an extraordinary opportunity to explore the underlying electrical, cellular, and molecular mechanisms of the human epileptic brain. It was from this dataset that we were able to identify endogenous regulators of MAPK signaling that may reduce or contribute epileptic signaling and therefore be transformed into future therapeutics for epilepsy.

description: The influence of extensive sedum-moss vegetated roofs on runoff water pollution loads was studied for four full scale installations located in southern Sweden. The aim of the study was to ascertain whether the vegetated roof behaves as a sink or a source of pollutants on annual basis. The pollution loads from vegetated roofs was also compared with the pollution loads from two non-vegetated roofs located in the study areas. The annual pollution loads were calculated based on the measured water quality and the volumes of annual precipitation and the annual roof runoff. Concentrations were measured during four precipitation events in November-December 2003. The following metals and nutrients were investigated: Cd, Cr, Cu, Fe, K, Mn, Pb, Zn, NO3-N, Tot-N, PO4-P, and Tot-P. The results show that, on the annual basis when total loads are considered, vegetated roofs behave as sink of nitrogen and source of potassium and phosphorus, the last with the exception of the oldest vegetated roof. The influence of vegetated roofs on annual heavy metals loads in runoff is less significant.

description: Objectives: To develop, and collect initial validity evidence for, a nationally-delivered Canadian In-Training examination (ITE) in Pediatric Emergency Medicine (PEM). Methods: A rigorous process was undertaken including blueprinting, item writing, piloting and scoring. Validity evidence collected from PDs included feedback on the blueprint, draft exam, and usefulness of the ITE, as well as feedback on the feasibility of the development and scoring process. Feedback was sought from residents on the fairness and usefulness of the ITE. Cronbach’s alpha was used to assess internal consistency of the ITE. Mean exam scores were compared by year of training, and exams were double scored to assess inter-rater reliability (IRR). Results: Ten Canadian PEM training sites participated in the project; 47 residents who completed the final pilot consented and were included in data analysis. Cronbach’s alpha coefficient for the ITE across items was 0.861, indicating high internal consistency. An ANOVA with linear contrast showed a significant linear association between year of training and mean score (F = 7.53, df = 2, p = 0.009). The intraclass correlation coefficient for ITE total score between PD and subcommittee raters was 0.85 (CI = 0.30 – 0.95), indicating high IRR. On a 5-point scale from ‘Not at All Feasible’ to ‘Extremely Feasible’, mean PD rating was 4.13 (SD ± 1.13) for the exam creation and delivery process, and 3.88 (SD ± 0.99) for the scoring process. Resident mean rating when asked about usefulness of the ITE was 3.18 (SD ± 1.03) on a 5-point scale from ‘Not at All Useful’ to ‘Extremely Useful’, and 98% of residents found it fair. Conclusions: The initial process of ITE creation and delivery resulted in an examination with a high internal consistency and inter-rater reliability. The ITE was useful to both PDs and residents, and feasible for PDs to create and deliver.

description: A now long-standing view of the software supply-industry is that "software is a product", whereby various software components are combined and coordinated in conveniently packaged forms that can provide solutions to specified ranges of practical engineering problems. The development in the use of the Internet has however more recently brought with it a new way of thinking about modelling, whereby the software can be employed as required, or \342\200\230on demand\342\200\231. Currently, the software developers/vendors sell their often expensive products to organisations that normally have projects from which they are able to recoup the costs of the packages and to pay the associated maintenance fees. Once the decision has been made to purchase a particular modelling product, the change to an alternative (which in each case again may be expensive) can be very difficult to justify. This imposes several limitations upon the organisations involved in the provision of urban-drainage modelling service. Therefore, a more current view is that it may in many cases be better to move away from a supply-driven to a demand-driven market model in which small packets of software are made available to the clients via Internet facilities in such a way that the clients are easily able to assemble these packets into software that serves their purpose for the period that it is required. This paper describes a new concept of hydroinformatics modelling software which has evolved as a response to these new technological
