- 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.

- 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

- 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.

- 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.

- 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.
