1800-talets mediesystem
- 2010
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Mediehistoria skrivs ofta utifrån ett medium i taget. Den här boken argumenterar istället för att historiens medier utvecklats tillsammans.Nya former, tekniker och praktiker har interagerat med gamla, innehåll har cirkulerat medierna emellan och rader av aktörer har aktivt relaterat till en helhet av uttrycksformer. Denna helhet var konturfast på ett vis som gör det befogat att tala om ett historiskt mediesystem: summan av en viss tids medier och deras inbäddning i sociala, politiska och ekonomiska villkor. I ett antal delstudier prövar boken möjligheterna att på närgången empirisk nivå undersöka 1800-talets mediesystem.

Deliverable 2.2 Possible market strategies for one stop shops of renovation of single family house. : Report prepared for Nordic Innovation Centre
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The document describes examples of missions, visions and strategies based on the potentialpiloting models defined in report 3.2. It is based on status of interest amongst thestakeholders, and the information, figures and challenges which were discussed in the reportD 2.1 Stakeholder interests. The different service models will request different missionsdepending on the stakeholder in charge of the model. Also visions and strategies could bedifferent depending on the composition of services (core business) offered within each pilot aswell as the additional services offered by sub suppliers and the network connected to the pilot.In the report D2.1 Stakeholders interests, the following 5 different piloting models aresuggested:Type 1 Joint venture of industry, retailers and contractorsType 2 Joint venture of construction/renovation, industry and architect/engineering companiesType 3 Complementary businesses expand their business into renovationType 4 Joint venture of type house producer, bank and home owner associationType 5 Energy/building consultant, real estate agent and financing institutions, e.g. bankIn this report we have described mission, vision and market strategies for 4 existing orproposed models; The Project Manager by Bolig Enøk, from Norway (type 1), ENRA concept(type 2) and K-Rauta & Rautia (type 3) from Finland, and ProjectLavenergi (type 2) fromDenmark. Cleantech by Dong Energy (type 3) from Denmark is also addressed, but notdescribed in detail. As there is no concrete examples representing two of the models fromD2.1 (types 4 and 5), we have made a theoretical exercise in developing mission, vision andmarket strategies for type 5 model, while type 4 is not handled.It may be concluded that there are commercial actors in different parts of the value chainwhich see an opportunity in developing different approaches of “one stop shops” for energyefficient holistic renovations. The concepts are still in a development phase and differ inrespect to how they are organised (as supply side). We may say that the pilots in the differentcountries also find inspiration from each other through this research project. Due to thecomplexity of a holistic renovation project, it is a prerequisite with good partnerships even inthe development phase. In all identified models there is however one main actor taking thelead and ownership to the business model.Independent of the business model the responsible company needs to make some strategicchoices. The starting point is the SWOT analysis which sums up all major challenges for therespective business model. How the strategies should be developed is described in this report.Although the main target group for this report is companies seeing an interest in developingbusiness models for renovation, we found some important issues identified in the SWOTanalysis which the authorities may influence including lack of interest in the market (need ofmore public attention through holistic campaigns), fragmented solutions (stop subsidisingsingle measures without a holistic plan), serious vs unserious companies (need of certificationsystems to build credibility), cost focus leads to limited renovation (need of subventionschemes for holistic retrofitting including tax deduction measures) and finally lack incompetence within companies (need of support to training and collaboration acrosscompanies).

Tidskriftsartikel (refereegranskat)abstract
- This study is an investigation of how members of the Norwegian and the Swedish parliaments relate to and perceive their relationships with the media. Based on surveys conducted among members of the Norwegian Storting and the Swedish Riksdag, we find that male MPs have more frequent and somewhat less formal relationships with media and journalists compared with female MPs. The results also suggest that male MPs have adapted to the media and their logic more than female MPs. Female MPs also appear to be more critical towards the requirements imposed on politicians who want to get media exposure, compared with male MPs. Analysis reveals that gender differences are smaller among Swedish than Norwegian MPs.

The framing of politics as strategy and game : A review of concepts, operationalizations and key findings
- 2012

Forskningsöversikt (refereegranskat)abstract
- A key concept in research on the media coverage of politics is the game or strategy frame. Contrasted with coverage of politics as issues, theframing of politics as a strategic game is marked by features such as winning and losing as the central concern and a focus on how candidates or parties are doing in opinion polls. The pervasiveness of such framing is, however, disputed since (1) the way in which the frames are conceptualized and operationalized differs significantly; and (2) while some use terms such as 'game frame' and 'strategy frame' as synonymous, others argue that there is a conceptual difference between them. Against this background, this article reviews research on the media's framing ofpolitics as a strategic game, what concepts have been used, and how they have been operationalized; and suggests a synthesis and ways of improving conceptual clarity and comparability in research on the media's use of strategy and/or game frames. © SAGE Publications 2011.

Case-based reasoning for assessment and diagnosis of depression in palliative care
- 2010
-
Ingår i: Proceedings - IEEE Symposium on Computer-Based Medical Systems. ; , s. 480-485
-
Konferensbidrag (refereegranskat)abstract
- The goal of the research presented is to create a computational framework and system architecture for clinical decision support in palliative care. The application focused is the classification of depression. The method under investigation is case-based reasoning, motivated by the complexity of the domain and a lack of generalized principles of sufficient coverage and strength for diagnosis and treatment. A system architecture is described and exemplified through an implemented prototype. The outcome of the research so far is a system that captures the properties intended, and for which a clinical test set-up has been defined. © 2010 IEEE.

Tidskriftsartikel (refereegranskat)abstract
- We compared online distributed information provided to patients with cancer in Scandinavian countries through the lens of governmentality. A secondary comparative qualitative analysis was conducted. Discourses in online patient information showed differences in governmentality techniques across the countries: Norway used a paternalist approach, Denmark an educative approach, and Sweden an individualistic approach and expected the patients to make the “right” decisions. Online information for patients with cancer in Denmark and Norway showed high professional and health care system involvement, whereas in Sweden, there was high patient involvement. There was almost no use of the person-centered approach among the online discourses

Smart meters and water leakage detection : A preliminary study
- 2019
-
Ingår i: I2MTC 2019 Proceedings. - 9781538634608
-
Konferensbidrag (refereegranskat)abstract
- The paper deals with water leakage beyond the meter at household level. The automatic leakage detection is emerging as priority task for scientists and technicians. Each possible solution must include the use of smart meters for the continuous survey of domestic water consumption. Water smart meters aren't widespread yet, and the few either are prototypes or exhibit not adequate battery and communication performance. The authors, participants to the EMPIR 17IND13 Metrowamet project, propose an embedded system that can work with different water sensors, whose characteristics have been suitably designed for respecting stringent requirements of energy efficiency, computational burden and wireless transmission capability.

Tidskriftsartikel (refereegranskat)abstract
- In the presence of fossil fuels, several environmental concerns, such as energy shortage, environmental pollution, and global warming may occur in the present century. In this respect, supercapacitors have been introduced as green energy storage systems playing a central role in providing a sustainable human society. In this work, an advanced strategy was initially demonstrated through various synergistic effects to synthesize cobalt(ii) metal-organic framework#CoMn2O4nanocomposites (Co(ii)-TMU-63#CoMn2O4NCPs) having interfaces adapted at tunable chemical nanocomposites for hybrid supercapacitors. The given NCPs showed excellent electrochemical performance at 7 A g−1current density endowed with a specific capacity of 156 mA h g−1(1420 F g−1) and good cycling stability at 10 A g−1current density, following 7000 cycles with 93.3% capacity retention. The hybrid supercapacitor was assembled using activated carbon (AC) as negative and NCPs as positive electrodes, which delivered specific energy of 38.54 W h kg−1and maximum-specific power of 2312.4 W kg−1with 89.5% capacity retention over 7000 cycles. The enhanced electrochemical performances of Co(ii)-TMU-63#CoMn2O4NCPs can be attributed to the high surface area, porous structure, open metal sites functioning as electron collectors to enhance electron transfer as well as unique morphology and synergistic effect between Co(ii)-TMU-63 and CoMn2O4. This work may inspire a new development of interface-adapted nanocomposite for advanced energy storage applications. © The Royal Society of Chemistry 2021.

- Age of Information (AoI) is a critical metric in status update systems as these systems require the fresh updates. This letter investigates the uplink of an Internet-of-Thing (IoT) network where L nodes transmit their information packets to a base station. The effects of the arrival rate of packets at the nodes, the number of nodes in the system, and queue length of each node have been studied by devising a discrete time Markov chain (MC) model. This model helps in predicting the values of AoI and probability of packet drops in such systems. The notion of first-in first-out is used for queuing, which transmits the oldest packet first, resulting in decreasing the overall AoI of the system. The results show that AoI increases with the increase in queue length, number of nodes and arrival rate and we quantify the aforementioned metrics using the MC model. The results found using the MC model are also validated using extensive simulations. © 2012 IEEE.

Age of Information in Backscatter Communication
- 2021
-
Ingår i: Internet Things. - Cham : Springer. ; , s. 67-80
-
Konferensbidrag (refereegranskat)abstract
- Age of Information (AoI) has been introduced to characterize the newness of data which is observed in real time. In other words, it is the measure of time elapsed since the generation of last received update about a process and is a vital metric in networks such as Internet of things (IoTs), especially when the application demands fresh updates. Most of the applications require fresh data e.g., applications related to environmental monitoring, smart agriculture, body area networks etc. On the other hand backscatter communication promises to resolve one of the most challenging issues of IoT devices, i.e., making them capable for communication without the batteries. The importance of AoI in backscatter communication is paramount to gauge performance of backscatter IoT networks. This chapter addresses the significance of AoI in backscatter communication and suggests some techniques to design a communication system with minimum AoI, maximum energy efficiency, and minimum outage. © 2021, Springer Nature Switzerland AG.

Tidskriftsartikel (refereegranskat)abstract
- A novel three-layer anode having the composition Ti/TiHx/Ni-Sb-SnO2 (Ti/TiHx/NATO) was successfully prepared by a spin-coating and pyrolysis process aiming at a long service lifetime and good electrocatalytic properties for ozone formation. The TiHx as an interlayer was produced by electrochemical cathodic reduction of a coated layer of the TiOx on the titanium substrate. Spin coating and thermal decomposition were used to deposit the Sn-Sb-Ni precursor on the surface of the prepared Ti/TiHx electrode. Cyclic and linear scanning voltammetry, Raman spectroscopy, scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to reveal the electrode performance and morphology. Results show that the onset potential for the oxygen evolution reaction (OER) of Ti/TiHx /NATO is higher than for Ti/NATO. They also indicate that the service lifetime of the Ti/TiHx/NATO is twice as long as the Ti/NATO at a current density of 50 mA.cm(-2) at room temperature. Electrochemical ozone generation and degradation of the methylene blue were investigated to confirm selectivity and activity of the electrodes. After 5 min electrolysis, a current efficiency for ozone generation of 56% was obtained the electrode with TiHx while 38% was obtained on Ti/NATO under same conditions. The results also confirm that the Ti/TiH x /NATO has a higher kinetic rate constant and decolorization efficiency for removal of the methylene blue compare to the Ti/NATO. The rate constant for the pseudo-first ordered reaction of methylene blue degradation showed high values of 350 x 10(-3) min(-1) for Ti/NATO and 440 x 10(-3) min(-1) for Ti/TiHx/NATO.

Determinants of social inequalities in cardiovascular disease among Iranian patients
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background and objectives: Cardiovascular disease (CVD) is the single largest cause of mortality in the world. Similar to other health issues, CVD is generally affected either by individual risk factors, which may influence the risk for developing an illness or its complications, or by social indicators (social determinants of health). There is evidence from developed countries which shows that the so-called "upstream factors"—including social determinants such as political, social, spiritual, cultural, and economic factors—may affect the prevalence and incidence of CVD. Scarce evidence from studies in low- and middle-income countries also suggests that social factors may affect the distribution of CVD across population groups. However, there is a dearth of such data in Iran, where only a few small-sizedstudies have focused on the social determinants of health. Therefore, the present thesis sought to fill this gap by assessing the effects of socioeconomic status (SES) on the distribution of CVD and the relevant inequalities within the Iranian context.Methods: This thesis is based on four studies, which used data from the Tehran Heart Center’s Databases. In Study I, a total of 44,820 patients who underwent coronary angiography at Tehran Heart Center between 2005 and 2010 were recruited. Then, their pre- and post-procedural data—including demographics, CVD risk factors, symptoms, and laboratory tests—were compared between men and women. In Study II, 6,246 patients with acutecoronary syndrome who were hospitalized between March 2004 and August 2011 were included and, based on their education and their employment status, were divided into high- and low-SES groups. Thereafter, the effect of SES on the in-hospital death of the patients was evaluated. In Study III, 20,165 patients with documented coronary artery disease who underwent coronary angiography at Tehran Heart Center were enrolled and CVD risk factors and severity (measured by the Gensini score) were assessed among the six major Iranian ethnic groups. In Study IV, 9,088 patients with acute coronary syndrome who were hospitalized at Tehran Heart Center between May 2007and June 2014 were recruited and the association between in-hospital death due to acute coronary syndrome and place of residence (rural/urban) was assessed using logistic regression adjusted for potential confounders.Results: In this thesis, the data analyses were based on the hypothesis that there is a potential association between the different socioeconomic indicators and the selected cardiovascular outcomes. In Study I, among the recruited participant, 25,363 men and 11,995 women had coronary artery disease and the women not only were significantly older, less educated, and more overweight but also had higher blood levels of triglyceride, cholesterol, low-density lipoprotein, high-density lipoprotein, and fasting blood sugar than the men. Moreover, hypertension and diabetes mellitus showed the strongest association in the women with coronary artery disease (OR=3.45, 95% CI: 3.28to 3.61 and OR=2.37, 95% CI: 2.26 to 2.48, respectively). In addition, the frequency of post-procedural recommendations for non-invasive procedures was higher in the women than in the men (20.1% vs 18.6%; P<0.001). In StudyII, of the 6,246 recruited patients with acute coronary syndrome, 3,290individuals were considered low-SES and 2,956 high-SES individuals. In-hospital death occurred in 79 (1.26%) patients: 1.9% in the low-SES and 0.6% in the high-SES groups. After adjustment for the possible cofounders, our multivariate analysis demonstrated a significant effect of the patients’ SES on their in-hospital death and a lower in-hospital mortality rate was shown in the high-SES patients (OR=0.30, 95% CI: 0.09 to 0.98; P=0.046). In Study III, the Fars (8.7%) and Gilak (8.6%) ethnic groups had the highest frequency of having at least four simultaneous risk factors. Additionally, the mean Gensini score was lowest in the Lurs (67.5±52.8) and highest among the Gilaks (77.1±55.9). The multivariable regression analysis indicated that the Gilaks showed the worst CVD severity (β: 0.056, 95% CI: 0.009 to 0.102; P=0.018), followed by the Turks (β: 0.032, 95% CI: 0.005 to 0.059; P=0.020), and the lowest CVD severity, was detected in the Lurs (β: -0.087, 95% CI: -0.146 to -0.027;P=0.004). Study IV showed that while smoking (P=0.002), positive family history of coronary artery disease (P=0.003), higher body mass index (P=0.013),and hyperlipidemia (P=0.026) were more prevalent in the urban patients, the rural patients showed lower educational levels (P<0.001) and higher frequency of unemployment (P=0.009). Meanwhile, in-hospital death occurred in 135 (1.5%) patients: 125 (1.5%) urban and 10 (1.2%) rural. To adjust the effects of the possible confounders, we utilized the Firth regression model, which showed no significant difference regarding in-hospital death betweenthe rural and urban patients (OR=1.57, 95% CI: 0.376 to 7.450; P=0.585).Conclusions: The aim of this thesis was to investigate the effects of social determinants (particularly SES) on CVD and its modifiable risk factors among Iranian patients. Results showed that medical treatment for CVD was more recommended (by treating physicians) to the women than the men, and the low-SES patients with acute coronary syndrome were more likely to die in the hospital than their high-SES counterparts. In addition, the thesis found heterogeneity in the distribution of the traditional risk factors for CVD as well as CVD severity in the major Iranian ethnic groups. Further, there were no differences concerning the in-hospital death rates due to acute coronary syndrome between the urban and rural patients after adjustment for the potential confounders.

- Background Diverse ethnic groups may differ regarding the risk factors and severity of coronary artery disease (CAD). This study sought to assess the association between ethnicity and CAD risk and severity in six major Iranian ethnic groups.Methods In this study, 20,165 documented coronary artery disease patients who underwent coronary angiography at a tertiary referral heart center were recruited. The demographic, laboratory, clinical, and risk factor data of all the patients were retrieved. The Gensini score (an indicator of CAD severity) was calculated for all, and the risk factors and severity of CAD were compared between the ethnical groups, using adjusted standardized residuals, Kruskal–Wallis test, and multivariable regression analysis.Results The mean age of the participants (14,131 [70.1%] men and 6034 [29.9%] women) was 60.7 ± 10.8 years. The Fars (8.7%) and Gilak (8.6%) ethnic groups had the highest prevalence of ≥4 simultaneous risk factors. The mean Gensini score was the highest for the Gilaks (77.1 ± 55.9) and the lowest among the Lors (67.5 ± 52.8). The multivariable regression analysis showed that the Gilaks had the worst severity (β 0.056, 95% CI 0.009 to 0.102; P = 0.018), followed by the Torks (β 0.032, 95% CI 0.005 to 0.059; P = 0.020). Meanwhile, the Lors showed the lowest severity (β −0.087, 95% CI −0.146 to −0.027; P = 0.004).Conclusions This study found that there was heterogeneity in CAD severity and a diverse distribution in its well-known traditional risk factors among major Iranian ethnic groups.

Tidskriftsartikel (refereegranskat)abstract
- Background: Given gender differences in the risk of coronary artery disease (CAD), the present study sought to investigate these dissimilarities amongst patients who underwent angiography at a major, tertiary heart hospital in Iran. Methods: Between 2005 and 2010, 44,820 patients who underwent coronary angiography were enrolled in a registry. Pre-procedural data such as demographics, CAD risk factors, presenting symptoms, and laboratory tests, as well as postprocedural data were collected. The data were, subsequently, compared between the men and women. Results: Out of the 44,820 patients (16,378 women), who underwent coronary angiography, 37,358 patients (11,995 women) had CAD. Amongst the CAD patients, the females were not only significantly older, less educated, and more overweight than were the males but also had higher levels of triglyceride, cholesterol, low-density lipoprotein, highdensity lipoprotein, and fasting blood sugar (P< 0.001). Of all the risk factors, hypertension and diabetes mellitus showed the strongest association in our female CAD patients (OR=3.45, 95%CI: 3.28-3.61 and OR=2.37, 95%CI: 2.26- 2.48, respectively). Acute coronary syndrome was more prevalent in the men (76.1% vs. 68.6%, P< 0.001), and chronic stable angina was more frequent in the females (31.4% vs. 23.9%, P< 0.001). With respect to post-procedural recommendations, the frequency of recommendations for non-invasive modalities was higher in the females (20.1% vs. 18.6%, P< 0.001). Conclusion: Hypertension and diabetes mellitus had the strongest association with CAD in our female patients. In the extensive CAD patients, medical treatment was recommended to the women more often.

- Background: Current evidence shows inequality in the outcomes of rural and urban patients treated at their place of residence. This study compared in-hospital mortality between rural and urban patients with acute coronary syndrome (ACS) to find whether there were differences in the outcome and received treatment.Methods: Between May 2007 and January 2018, patients admitted with ACS were included. The patients’ demographic, clinical, and laboratory data, as well as their in-hospital medical courses, were recorded. The association between place of residence (rural/urban) and in-hospital mortality due to ACS was evaluated using logistic regression adjusted for potential confounders.Results: Of 9088 recruited patients (mean age =61.30±12.25 y; 5557 men [61.1%]), 838 were rural residents. A positive family history of coronary artery disease (P=0.003), smoking (P=0.002), and hyperlipidemia (P=0.026), as well as a higher body mass index (P=0.013), was seen more frequently in the urban patients, while the rural patients had lower education levels (P<0.001) and higher unemployment rates (P=0.009). In-hospital mortality occurred in 135 patients (1.5%): 10 rural (1.2%) and 125 urban (1.5%) patients (P=0.465). The Firth regression model, used to adjust the effects of possible confounders, showed no significant difference concerning in-hospital mortality between the rural and urban patients (OR, 1.57; 95% CI, 0.376 to 7.450; P=0.585).Conclusion: This study found no significant differences in receiving proper treatment and in-hospital mortality between rural and urban patients with ACS.

Tidskriftsartikel (refereegranskat)abstract
- Background: Socioeconomic status (SES) can greatly affect the clinical outcome of medical problems. We sought to assess the in‑hospital mortality of patients with the acute coronarysyndrome (ACS) according to their SES.Methods: All patients admitted to Tehran Heart Center due to 1st‑time ACS between March 2004 and August 2011 were assessed. The patients who were illiterate/lowly educated (≤5 years attained education) and were unemployed were considered low‑SES patients and those who were employed and had high educational levels (>5 years attained education) were regarded as high‑SES patients. Demographic, clinical, paraclinical, and in‑hospital medical progress data were recorded. Death during the course of hospitalization was considered the end point, and the impact of SES on in‑hospital mortality was evaluated.Results: A total of 6246 hospitalized patients (3290 low SES and 2956 high SES) were included (mean age = 60.3 ± 12.1 years, male = 2772 [44.4%]). Among them, 79 (1.26%) patients died. Univariable analysis showed a significantly higher mortality rate in the low‑SES group (1.9% vs. 0.6%; P < 0.001). After adjustment for possible cofounders, SES still showed a significant effect on the in‑hospital mortality of the ACS patients in that the high‑SES patients had a lower in‑hospital mortality rate (odds ratio: 0.304, 95% confidence interval: 0.094–0.980; P = 0.046).Conclusions: This study found that patients with low SES were at a higher risk of in‑hospital mortality due to the ACS. Furthermore, the results suggest the need for increased availability of jobs as well as improved levels of education as preventive measures to curb the unfolding deaths owing to coronary artery syndrome.

- Purpose – The aim of the study is to investigate whether there are any differences between the attitudes towards participation in development programmes of entrepreneurs who are immigrants and those who are native-born. Design/methodology/approach – Several statistical methods, including a binary logistic regression model, were used to analyse a unique, firm-level dataset collected by the Swedish Small Business Forum in October and November 2012. The dataset was based on a questionnaire composed of 60 closed questions that was completed by 531 participants representing 395 companies. Findings – Based on the analysis of 15 different attitude variables, the empirical findings are that immigrant managers/owners are more likely to show a positive attitude to participation in development programmes, in terms of nine of those attitude variables, than their native counterparts. Because there are no data about second generation of immigrants in the sample, thus, this category may have had an impact on the results. However, there is no possibility to identify any impact on the results. Originality/value – There is no prior research focusing specifically on this question, and to the authors' knowledge, this study is the first that has attempted to deal with the issue. This study is based on a recent and unique database, and provides new evidence on the relationship between ethnicity and attitude towards participation in development programmes among entrepreneurs. Its context is different from that of prior research.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: The main purpose of this study is to provide empirical evidence which identifies the impact of ethnicity and other relevant variables on external capital acquisition among Swedish women-owned businesses at start-up. Design/methodology/approach: Several methods have been employed to analyze the sample including a binary logistic regression model. The sample consists of 836 women-owned businesses in southeast Sweden; 97 immigrant-owned, 739 native born-owned. Findings: The results indicate that there are partly significant differences between native women-owned firms and immigrant woman-owned businesses at start-up. Unlike the native-owned firms, the immigrant woman-owned businesses rely more on loans from family members and less on bank loans. Practical implications: The results reveal that age has a positive impact on loans from family members, while the additional job outside one's own business, the amount of the owner's personal start-up capital and firm size positively influenced access to capital from banks. The owners' level of education, previous business experience, the legal form taken by the firm and the industry affiliation conversely played no significant role in explaining the women owners' attitudes toward loans from either friends or the bank. Originality/value: To the authors' knowledge, this study is the first empirical investigation addressing this issue in the Swedish context.

Tidskriftsartikel (refereegranskat)abstract
- This research explores the differences in informal capital acquisition between female- and male-owned firms in the start-up stage in Sweden. A binary logistic regression model is used to analyse a sample including 836 female- and 1928 male-owned firms in 2008, providing 47,022 observations. The results indicate that the main explanatory variable, gender, is significant in distinguishing between female- and male-owned firms with regards to the use of informal capital in terms of loans from family members. Thus, female-owned firms tend to rely more on loans from family members than male-owned firms. The findings also indicate that one control variable, namely owners previous experience of starting up a company, negatively influences the use of loans from family members as a financing source in the start-up stage. This study is based on a unique and large sample including many different variables compared with previous research. Knowledge on the differences between Swedish female- and male-owned firms in using informal capital in the start-up stage is limited and ambiguous. The presented results contribute to research into small firm financing by adding insight into the relationships between informal capital acquisition, gender, and other relevant variables.

Tidskriftsartikel (refereegranskat)abstract
- Small firms in general have limited access to funding, which is a major problem for entrepreneurs. In particular, this problem is evident for women and ethnic minority groups. The purpose of the study is to examine empirically the impact of gender, ethnicity and other relevant variables on the access to external financing of new small firms. A sample of 2,764 female– and male–owned small businesses, based on a unique and large database gathered through interviews, was investigated employing binary logistic regression models. The results suggest that both gender and ethnicity are significant explanatory variables influencing the access to external capital at the start–up stage. Entrepreneurs' age, experience of starting businesses and education, as well as additional jobs beside their own business, are other variables that influence the way in which entrepreneurs finance their business. Moreover, firm characteristics in terms of personal start–up capital, firm size and legal form have an impact on financing behaviour at start–up. Since the knowledge about this issue is limited, the results of this study add to our understanding of the variables affecting the behaviour of small business endeavours in seeking funding at start–up

Tidskriftsartikel (refereegranskat)abstract
- The present study investigates whether owner and firm characteristics influence the use of external financing sources among Swedish small-owned firms at start-up stage. Several methods, including multinomial binary logistic regression have been employed to analyse a unique and comprehensive firm-level database, consisting of 2,814 firms gathered through interviews. The results show that three variables, i.e., loans from family members and friends, bank debt and funding from angel investors, are significant in distinguishing between Swedish native and immigrant-owned firms in the acquisition of financial sources in start-up. In addition, immigrant-owned firms tend to relay more on informal financial sources e.g. loan from family member, friends and angel investors, and less on bank loan. Furthermore, whereas, ethnicity influences the change of all these four variables significantly, gender merely affects loans from family members. Other variables, such as the owners’ age, prior experience in business, education, having an additional job beside one’s own business, the amount of personal start-up capital and firm size, as well as legal form and industry affiliation are partly important to explain the acquisition use of external capital at start-up stage.

Tidskriftsartikel (refereegranskat)abstract
- Celulose nanofibers are lightweight, recycable, biodegradable, and renewable. Hence, there is a great interest of using them instead of fossil-based components in new materials and biocomposites. In this study, we disclose an environmentally benign (green) one-step reaction approach to fabricate lactic acid ester functionalized cellulose nanofibrils from wood-derived pulp fibers in high yields. This was accomplished by converting wood-derived pulp fibers to nanofibrillated “cellulose lactate” under mild conditions using lactic acid as both the reaction media and catalyst. Thus, in parallel to the cellulose nanofibril production, concurrent lactic acid-catalyzed esterification of lactic acid to the cellulose nanofibers surface occured. The direct lactic acid esterification, which is a surface selective functionalization and reversible (de-attaching the ester groups by cleavage of the ester bonds), of the cellulose nanofibrils was confirmed by low numbers of degree of substitution, and FT-IR analyses. Thus, autocatalytic esterification and cellulose hydrolysis occurred without the need of metal based or a harsh mineral acid catalysts, which has disadvantages such as acid corrosiveness and high recovery cost of acid. Moreover, adding a mineral acid as a co-catalyst significantly decreased the yield of the nanocellulose. The lactic acid media is successfully recycled in multiple reaction cycles producing the corresponding nanocellulose fibers in high yields. The disclosed green cellulose nanofibril production route is industrial relevant and gives direct access to nanocellulose for use in variety of applications such as sustainable filaments, composites, packaging and strengthening of recycled fibers.

Tidskriftsartikel (refereegranskat)abstract
- We herein report that supported copper nanoparticles (CuNPs) on commercially available controlled pore glass (CPG), which exhibit high mechanical, thermal and chemical stability as compared to other silica-based materials, serve as a useful heterogeneous catalyst system for 1,3-dipolar cycloadditions (“click” reactions) between terminal alkynes and organic azides under green chemistry conditions. The supported CuNPs-CPG catalyst exhibited a broad substrate scope and gave the corresponding triazole products in high yields. The CuNPs-CPG catalyst exhibit recyclability and could be reuced multiple times without contaminating the products with Cu.

- In this work, photoresponsive nanomechanical systems were prepared through the intercalation of positively charged photoswitching molecular jacks (azobenzene ionic liquids, Azo-ILs) within montmorillonite (MMT) layers (MMT@Azo-ILs). The study shows that MMT@Azo-ILs are photosensitive and the synthesized molecular jacks could change the basal distances of MMT layers upon UV irradiation. These changes come from changes in the structure and geometry of Azo molecules (i.e., cis-trans isomerization) between clay layers upon UV irradiation. The prepared photoresponsive nanomechanical systems were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), thermogravimetric analysis (TGA), energy-dispersive X-ray spectroscopy (EDX), field-emission scanning electron microscope (FE-SEM). Moreover, the in vitro release studies were performed in different conditions (upon UV irradiation and darkness) in pH 5.8 at 34 ± 1 °C, and it was found that the release rates from drug loaded MMT@Azo-ILs were higher upon UV irradiation in comparison with the release rates in darkness. According to the release studies, the prepared photoresponsive carriers might be considered as an excellent potential candidate in order to formulate smart sunscreens. © 2017 American Chemical Society.

A Prediction for the Conversion Performance of H2S to Elemental Sulfur in an Ionic-Liquid-Incorporated Transition Metal Using COSMO-RS
- 2022

Ingår i: CHEMISTRY-SWITZERLAND. - : MDPI AG. - 2624-8549. ; 4:3, s. 811-826

Tidskriftsartikel (refereegranskat)abstract
- In the present study, the conversion performance of hydrogen sulfide (H2S) to elemental sulfur in ionic-liquid-incorporated transition metals (ILTMs) is predicted using a conductor-like screening model for realistic solvents (COSMO-RS). The predictions were made via the establishment of a correlation between the conversion performance and solubility of H2S in ionic liquids (ILs). All molecules involved were optimized at the DFT/TZVP/M06 computational level and imported on the COSMOtherm program at equimolar conditions. For validation purposes, the solubility of ILs was predicted at 1 bar pressure. Simple regression analysis was used to establish a relationship between the solubility and conversion performance of H2S. The results indicate that the solubility prediction of ILs is accurate (R-2 = 93.40%) with a p-value of 0.0000000777. Additionally, the conversion performance is generally found to be dependent on the solubility value. Furthermore, 1-butyl-3-methylimidazolium chloride [bmim][Cl] was chosen as the base IL for incorporating the transition metal, owing to its solubility and selectivity to H2S. The solubility trend of ILTMs is found to follow the following order: [bmim][NiCl3] > [bmim][FeCl4] > [bmim][CoCl3] > [bmim][CuCl3]. According to the viscosity measurements of ILTMs, [bmim][NiCl3] and [bmim][FeCl4] exhibited the highest and lowest viscosity values, respectively. Therefore, [bmim][FeCl4] is a promising ILTM owing to its higher solubility and low viscosity for the application studied.

- In this paper we present an integrating CMOS Active Pixel Sensor (APS) circuit to be used with scintillator type X-ray sensors for intra oral dental X-ray imaging systems. Different pixel architectures were constructed to explore their performance characteristics and to study the feasibility of the development of such systems using the CMOS technology. A prototype 64 x 80 pixel array has been implemented in a CMOS 0.8 mum double poly n-well process with a pixel pitch of 50 mum. A spectral sensitivity measurement for the different pixels topologies, as well as measured X-ray direct absorption in the different APSs are presented. A measurement of the output signal showed a good linearity over a wide dynamic range. This chip showed that the very low sensitivity of the CMOS APSs to direct X-ray exposure adds a great advantage to the various CMOS advantages over CCD-based imaging systems,

- We present in this paper an integrating CMOS Active Pixel Sensor (APS) circuit coated with scintillator type sensors for intra-oral dental X-ray imaging systems. The photosensing element in the pixel is formed by the p-diffusion on the n-well diode. The advantage of this photosensor is its very low direct absorption of X-rays compared to the other available photosensing elements in the CMOS pixel. The pixel features an integrating capacitor in the feedback loop of a preamplifier of a finite gain in order to increase the optical sensitivity. To verify the effectiveness of this in-pixel preamplification, a prototype 32 x 80 element CMOS active pixel array was implemented in a 0.8 mum CMOS double poly, n-well process with a pixel pitch of 50 mum. Measured results confirmed the improved optical sensitivity performance of the APS. Various measurements on device performance are presented.

Architecture and circuit design of photon counting readout for X-ray imaging sensors
- 2007
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Hybrid pixel array detectors for X-ray imaging are based on different technologies for sensor and readout electronics. The readout electronics are based on standard CMOS technologies that are experiencing continuously rapid improvements by means of down-scaling the feature sizes, which in turn lead to higher transistor densities, lower power consumption, and faster circuits. For pixel-array imaging sensors the improvements in CMOS technology opens up new possibilities of integrating more functionality in the pixels for local processing of the sensor data. However, new issues related to the tight integration of both analog and digital processing circuits within the small area of a pixel must also be evaluated. The advantages of down-scaling the CMOS technology can be utilized to increase the spatial resolution by reducing the pixel sizes. Recent research indicates however that the bottleneck in reaching further spatial resolution in X-ray imaging sensors may not be limited by the circuit area occupied by the functions necessary in the pixels, but are instead related to problems associated with charge-sharing of charges generated by the sensor which are distributed over a neighbourhood of pixels and will limit the spatial resolution and lead to a distortion of the energy spectrum. In this thesis a mechanism to be implemented in the readout circuits is proposed in order to suppress the charge-sharing effects. The proposed architecture and its circuit implementation are evaluated with respect to circuit complexity (area) and power consumption. For a photon-counting pixel it is demonstrated that the complete pixel, with charge-sharing suppression mechanism, can be implemented using 300 transistors with an idle power consumption of 2.7μW in a 120nm CMOS technology operating with a 1.2V power supply. The improvements in CMOS technology can also be used for increasing the range of applications for X-ray imaging sensors. In this thesis, an architecture is proposed for multiple energy discrimination, called color X-ray imaging. The proposed solution is the result of balancing the circuit complexity and the image quality. The method is based on color sub-sampling with intensity biasing. For three-level energy discrimination, that corresponds to color imaging systems for visible light with R, G, and B color components, the increase in circuit complexity will be only 20% higher than that for the Bayer method but results in significantly better image quality. As the circuit complexity in the digital processing within each pixel is increased, the digitally induced noise may play an increasingly important role for the signal-to-noise ratio in the measurements. In this thesis an initial study is conducted regarding how the digital switching noise affects the analog amplifiers in the photon-counting pixel.
