    This study investigates the historical trajectory and future estimations of cumulative installed power and geographical distribution of Ground-Mounted Photovoltaic parks (GMPV-parks) inSweden. Historical data of cumulative installed power from GMPV-parks were compiled, and future estimations for 2024-2027 were projected using trend analysis. Factors influencing thegeographical distribution of GMPV-parks were analyzed, focusing on national factors. A sensitivity analysis was conducted to assess variations in future estimations based on parameter adjustments. Results show a exponential growth in cumulative installed power historically, with projections suggesting a similar trend in the future. Geographical placements are expected to follow historical trends, driven by solar radiation, climate, and urban proximity. Overall, this study provides valuable insights for those aiming to expand solar energy capacity in Sweden, emphasizing the importance of regulatory frameworks and technological advancements in shaping future integration efforts

    UV curing: An alternative method for fixation of beta-carotene containing microparticles substances onto cotton fabrics by acrylic binder

    Capsulation technology is one of the methods that have been utilized for gaining various functional properties of textile materials. With the technology, in recent years, textile materials have been made to exhibit functions such as vitamins, fragrances, moistening effect, insect repellent, and anti-cellulite. To establish permanent bonding between capsule-based materials and textile materials, which also provides efficiency against washing, crosslinking agents are used. Commercial capsules are applied to a fabric by using acrylics or polyurethanes as the cross-linker at a drying temperature of around 100 degrees C and thermo-fixation conditions are between 110 and 130 degrees C. The capsules used for fragrance and aromatherapy applications, which contain volatile oil, can be affected in high-temp conditions that cause evaporation and degradation of active ingredient. In this study, beta-carotene as the active ingredient was dispersed within ethyl cellulose via spray drying first and then applied to textile materials to maintain the tanning effect. Besides thermal curing, the UV curing process with different photoinitiators will be utilized for the fixation of capsules onto textile materials. Hence, the UV curing technique will be used as an alternative to the thermal fixing of conventional cross-linkers. After application of the capsules onto textile materials, characterization, and various efficiency tests such as color measurement, X-ray diffraction, thermogravimetric analysis were performed. As a result, textiles containing beta-carotene microparticles that are resistant to 10 washing cycles were produced. Moreover, all the beta-carotene fixed fabric showed antioxidant activity and thermal stability. Consequently, it could be said that the UV curing process on textile materials can be an alternative curing process to the thermal curing process

    © 2021 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY-NC-ND 4.0 licenseBackground: 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods: This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494. Findings: Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation: Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.
