- This paper addressed the question whether there is an environmental advantage of using DECT phones instead of GSM phones in offices. The paper also addresses the environmental compatibility of Electrochemical Pattern Replication (ECPR) compared to classical photolithography based microscale metallization (CL) for pattern transfer. Both environmental assessments consider electricity consumption and CO2 emissions. The projects undertaken were two comparative studies of DECT phone/GSM phone and ECPR/CL respectively. The research method used was probabilistic uncertainty modelling with a limited number of inventory parameters used in the MATLAB tool. Within the chosen system boundaries and with the uncertainties added to input data, the ECPR is to 100 % probability better than CL and the DECT phone is to 90% better than the GSM phone.

- This paper focuses on uncertainty analysis, that is, how the input data uncertainty affects the output data uncertainty in small but realistic product systems is modeled. The motivation for the study is to apply the Monte Carlo simulation for uncertainty estimation in life cycle inventory and environmental assessment of microelectronics applications. This paper addresses the question whether there is an environmental advantage of using DECT phones instead of GSM phones in offices. The paper also addresses the environmental compatibility of Electrochemical Pattern Replication (ECPR) compared to classical photolithography based microscale metallization (CL) for pattern transfer. Both environmental assessments in this paper consider electricity consumption and CO2 emissions. The projects undertaken are two comparative studies of DECT phone/GSM phone and ECPR/CL respectively. The research method used was probabilistic uncertainty modelling with a limited number of inventory parameters used in the MATLAB tool. For the DECT/GSM study the results reflects the longer DECT technical life which is an environmental advantage. For the Electrochemical Pattern Replication (ECPR)/classical photolithography based microscale metallization (CL) study the results reflects the fewer number of process steps and the lower electricity consumption needed by the ECPR to reach the functional unit. The difference in results is large enough to be able to draw conclusions, as the processes with the highest electricity consumption within the system boundaries have been determined. Based on earlier work a straightforward method to include uncertainty for input life cycle inventory data is used to quantify the influence of realistic errors for input data in two microelectronic applications. The conclusion is that the ECPR technology is more electricity efficient than CL in producing one layer of copper on a silicon wafer having a diameter of 20.32 cm. The conclusion is that the longer technical life of a cordless DECT phone is reflected in an electricity/CO2 comparison with a GSM phone, if use in an office is considered. Reasonable uncertainty intervals used for the input life cycle inventory data for the studied DECT/GSM and ECPR/CL system does affect the outcome of calculation of emission of CO2 but not to the degree that conclusions are not valid.Different uncertainty intervals and probability distributions could apply for different types of data and the interrelated input data dependence should be investigated. Today there exist very few life cycle inventory (LCI) data with the range of uncertainty for input and output elements. It must be emphasized that the upcoming LCI databases should have standard deviation characterized LCI data just as the Swiss ecoinvent LCI database.More inventory parameters and probability distributions characteristic for microsystems could be included and error analysis should be applied to future life inventory methodology, especially for future packaging concepts such as System-In-a-Package and System-On-a-Chip comparisons.

The motivation for the study is to apply the Monte Carlo simulation for uncertainty estimation in life cycle inventory and environmental assessment of microelectronics applications. The present paper addresses the question whether there is an environmental advantage of using digital enhanced cordless telecommunications (DECT) phones instead of global system for mobile (GSM) phones in offices. This paper also addresses the environmental compatibility of electrochemical pattern replication (ECPR) compared to classical photolithography-based microscale metallization (CL) for pattern transfer. Both environmental assessments in this paper consider electricity consumption and CO2 emissions and the projects undertaken are two comparative studies of DECT phone/GSM phone and ECPR/CL, respectively. The research method used was probabilistic uncertainty modeling with a limited number of inventory parameters used in the MATLAB tool. For the DECT/GSM study the results reflects the longer DECT technical life which is an environmental advantage. For the electrochemical pattern replication (ECPR)/classical photolithography based microscale metallization (CL) study the results reflects the fewer number of process steps and the lower electricity consumption needed by the ECPR to reach the functional unit.

ECPR (ElerctroChemical Pattern Replication) : Metal Printing for Advanced Package Applications

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- ECPR (electrochemical pattern replication) is a new fabrication process for the production of microstructures in conducting materials. Using ECPR, the cost of metallization for advanced packaging solutions can be significantly reduced compared to using lithography based processes. The technology utilizes a reusable master electrode for electrochemical pattern replication, which enables direct metallization with short cycle times, high throughput and comparably low equipment investments. ECPR provides metallization on most substrates such as silicon wafers, ceramic substrates and flexible or rigid organic substrates. The technique currently enables pattern transfer of copper structures down to 5/5 /spl mu/m line/space with uniform material distribution and high resolution patterns with small line width variations. Results from replication studies on both ultrathin polyimide substrates and silicon wafers are presented.

Glimten i läkarens blick : Foucault, psykiatrihistoria och "antropologiska kategorier"

Tidskriftsartikel (refereegranskat)abstract
- In The Archaeology of Knowledge Michel Foucault teaches us to discard or at least decentre the historical subject and to call all the unquestioned continuities by which we organize the discourses we want to analyse in question. The aim of this study is to discuss the implications of such a theoretical approach when it is applied to a scholarly project that focuses on a certain historical individual, the Swedish psychiatrist, Bror Gadelius, and his role in the formation of a specific discursive formation, early 20th-century psychiatry in Sweden.

Hemligheternas värld: Bror Gadelius och psykiatrins genombrott i det tidiga 1900-talets Sverige
- 2017

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this dissertation is to examine the transformation of psychiatry in Sweden in the early 20th century. At the turn of the century, 1800–1900, a form of psychiatry appeared that in many aspects sought to differentiate itself from the discipline as it had emerged during the previous century. Theoretically there was a shift in attention from the brain to the mind and measurers were taken to make the care for the mentally ill more humanitarian. To a great extent this was a result of the writings and actions of Bror Gadelius, Sweden’s leading psychiatrist at the time. This phase in the history of psychiatry is analyzed from the perspective of two intertwined processes, the medicalization of madness and deviance and scientific specialization; as well as the nexus of power and humanism characteristic for psychiatric discourse. It is suggested that the professed new identity of psychiatry formed an essential part of Gadelius’ strategies to spread a psychiatric view on human mentality in society and to safeguard the discipline’s borders against other medical specialties. The humanitarian aspects are investigated in patient records and the narrative representation of patients in case stories. One conclusion is that power in the asylum on the one hand was a condition for the humanitarian treatment of the mentally ill, but that on the other hand inherent norms and discipline put a limit to the free expression of the patient as well as the therapeutic potential in the patient-doctor relationship.
