- Prepared meals distributed by municipalities is a service to elderly people, or persons with health related impairments, who live in their own home, have difficulties preparing their own food and cannot meet their food requirements in any other way. This study aimed to provide a brief picture of how elderly people living at home perceive the food they receive through their municipal food service and what is important to them. The data was collected using questionnaires. 274 out of 276 participants answered the questionnaire (n=173 women 62% and n=101 man 37%). The data was analyzed using Principal Component Analysis (PCA).The results showed that the elderly persons receiving meals through the service were often satisfied, especially with the size of the portions and the delivery time. Those who had been using the food delivery service for a longer time were not satisfied with the alternative dishes they were been offered. There was no significant difference between the views of either gender. Further, those who were receiving special food were, in general, unsatisfied with the meals delivered.Development of the food distribution service by systematic quality insurance and interactive knowledge exchange between the producers and consumers seems to be a way to promote a more holistic and individual adjusted service. Evaluation of the municipal FD service is a powerful tool that can contribute to the development of this service. The food service can be improved and consequently even the quality of life and health of its receivers. The present survey should be revisited and developed in order to detect differences between genders.

Forskningsöversikt (refereegranskat)abstract
- Introduction: Help at birth is one of the historically oldest volunteers supports that a woman has offered to another woman. One of the reasons for high maternal and infant mortality was identified as a lack of basic medical knowledge among the woman who helped during birth and this required immediate action to secure the survival of nations. When the Church and government made demands for education and professional license, the voluntary help at birth transformed into an educated and paid profession for women. The study aimed to describe the evolution of women’s education and the midwifery profession in Nordic countries from the 1600s until today. Methods: Historical and contemporary documents, research and grey literature, are drawn together to provide a historical description of the midwifery professional development and education in Nordic countries. Results: In the Nordic countries, governments from the 1600s had significant problems with high maternal and infant mortality. Most vulnerable were unmarried women and their children. To change the trend, northern countries had been inspired by France, Holland, England, and Germany, which had introduced education and a professional license for midwives. The targeted and systematic investment in midwifery education, followed by industrialization and welfare development in Nordic countries, has resulted in one of the highest survival rates for mothers and infants in the world today. In parallel with this, it has created the first female paid profession in history. Today, midwifery education is at the university level in all Nordic countries, and the certified midwife is responsible for pre- and post-natal care and normal birth. In Sweden, Norway, and Iceland, the midwife’s responsibility also includes contraception counseling and prescription of drugs for birth control purposes. Conclusions: The education and professional licenses have contributed to a progressively improved care of birth women and infants. The professional and licensed midwife is positioned in society as an essential player in the current development of pre- and post-natal care. Furthermore, the graduated and licensed midwife positioned herself as the first paid professional female profession in modern history.

Tidskriftsartikel (refereegranskat)abstract
- Selective transformation of BHMF (2,5-bis(hydroxymethyl)furan) to THFDM (tetrahydrofuran-2,5-dimethanol) over a variety of structured Ni/Sx-Z1−x catalysts was investigated. The effects of support, Ni loading, solvent, temperature, pressure, and particle size on the conversion and selectivity were studied. Among them, the 10 wt% Ni catalyst supported on the SiO2:ZrO2 weight ratio of 90:10 (10NiS90Z10) exhibits the best performance in terms of BHMF conversion and THFDM selectivity. Its good performance was attributed to its well-balanced properties, that depend upon the ZrO2 content of the support in combination with SiO2, the active Ni sites-support interaction, and acidity/basicity ratio of each catalyst resulting in different Ni dispersions. Importantly, the 10NiS90Z10 catalyst showed a stable selectivity to THFDM (>94%), with 99.4% conversion of BHMF during 2 h reaction time. Poor catalytic activity resulted from excessive ZrO2 content (>10 wt%). The structural, textural, and acidity properties of NiSi100−y-Zry catalysts, tuned by selectively varying the Ni amount from 5 to 15 wt%, were critically investigated using numerous material characterization techniques. Catalyst recycling experiments revealed that the catalyst could be recycled several times without any measurable loss of catalytic activity.

CO2 hydrogenation to light olefins using In2O3 and SSZ-13 catalyst-Understanding the role of zeolite acidity in olefin production
- 2023

Ingår i: Journal of CO2 Utilization. - 2212-9820. ; 72

Tidskriftsartikel (refereegranskat)abstract
- With the aim to explore the effect of acidic properties of zeolites in tandem catalysts on their performance for CO2 hydrogenation, two types of SSZ-13 zeolites with similar bulk composition, but different arrangements of framework Al, were prepared. Their morphology, pore structure, distribution of framework Al, surface acid strength and density, were explored. The results showed that SSZ-13 zeolites with isolated aluminum distribution could be successfully synthesized, however, they contained structural defects. During calcination, the framework underwent dealumination, resulting in weaker Brønsted acidity and lower crystallinity. The morphologies were, however, well preserved. Compared with the SSZ-13 zeolites, synthesized conventionally, these low acidity SSZ13 zeolites with isolated aluminum were good zeolite components in bifunctional catalysts for CO2 hydrogenation to light olefins. By combining with In2O3, they exhibited better catalytic performance for light olefin production during CO2 hydrogenation at low temperatures. Na+ cation exchange was used to adjust the Brønsted acid site (BAS) density with only minor changes to the cavity structure. Comparative experiments established that the BAS density of the zeolite, rather than the framework Al distribution (BAS distribution), overwhelmingly affected catalyst stability and product selectivity. A higher acid density reduced the selectivity for light olefins, while lower acid density tended to form inert coke species leading to rapid deactivation. The ideal amount of BAS density in the bifunctional catalyst was approximately 0.25 mmol/g, which exhibited 70% selectivity for light olefins among hydrocarbons, and 74% selectivity for CO without deactivation, after 12 h reaction at 325 celcius and 10 bar.

Tidskriftsartikel (refereegranskat)abstract
- Moderately acidic aluminophosphates (SAPOs) are often integrated with methanol synthesis catalysts for the hydrogenation of CO2 to olefins, but they suffer from hydrothermal decomposition. Here, an alternative SSZ-13 zeolite with high hydrothermal stability is synthesized and coupled with an In2O3 catalyst in a hybrid system. Its performance regarding selectivity for olefins and coke formation was investigated for CO2 hydrogenation under varying temperatures and pressures. Various reactions occur, producing mainly CO and different hydrocarbons. The results indicate that the hydrogenation of hydrocarbons are dominant at high temperatures (around 400 °C) over SSZ-13 zeolite with a high acid density and that the coke deposition rate is slow. Polymethylbenzenes are the main coke species, but the selectivity for light olefins is low among hydrocarbons at high temperatures. However, at low temperatures (around 325 °C), and especially under high pressure (40 bar), methanol disproportionation becomes significant. This results in an increased selectivity for light olefins; however, it also leads to a rapid coke deposition, which gives inactive adamantanes as the main coke species that block the pores and cause rapid deactivation. However, after coking at 325 °C and regeneration at 400 °C under the reaction atmosphere, the accumulated adamantanes can be decomposed into smaller coke species, which reopens the channel structure and generates modulated active sites within the zeolite, resulting in a higher yield of olefins without deactivation. The performances of acidic SSZ-13 zeolites, with varying ratios of Si/Al in transient experiments, further verified that a dynamic balance exists between the formation and degradation of coke within the SSZ-13 zeolite during a long-term CO2 hydrogenation reaction. This balance can be achieved by optimizing the reaction conditions to match the acid density of the catalyst. Using the conditions of 20 bar and 375 °C, with a H2 to CO2 mole ratio of 3, the results obtained for the precoked hybrid catalysts of In2O3 and SSZ-13 (Si/Al = 25) exhibited very stable activity, with the selectivity for light olefins (based on hydrocarbons formed) of max. 70% after 100 h time-on-stream. This work provides new insights into the design of stable hybrid catalysts, especially the influence of a precoking process for SSZ-13 zeolite in the production of light olefins.
