Journal article (peer-reviewed)abstract
- This study elucidates the nursing of undernourished patients as experienced by eight registered clinical nurses and five nursing assistants by using content analysis. The participants' narratives describe the inner perspective of caring for undernourished patients, known in Sweden as `the thin ones'. Categories identified were: frustration in nursing, joy in nursing and that undernourishment is taboo. The taboo was narrated as feelings of guilt and shame. Frustration in nursing could be seen as feeling stressed, exposed, lonely, powerless, helpless, and being torn between demands and needs. Joy in nursing was experienced when creating a trusting relationship, promoting pleasure in the meal situation and working with respect for each individual's life-style and context of life. Understanding staff members' views is important when implementing guidelines as well as in the teaching situation in order to identify where staff stand with regard to knowledge and attitudes.

Setting the stage for 100GbE serial standard - The HECTO project
- 2010
-
In: World Telecommunications Congress 2010, WTC 2010. - : VDE Verlag GmbH. ; , s. 118-123
-
Conference paper (peer-reviewed)abstract
- The standard for 100GbE will be adopted in 2010, defining transmission via 4 x 25 Gbit/s. A solution employing 1 x 100 Gbit/s would be cheaper - if the appropriate integrated components were available. These components now have been developed in the project HECTO. The project is shortly described and the main results are presented: the achieved performance of the components itself and the achieved system performance in a field trial. The complete ETDM system with monolithically integrated transmitter and receiver modules featured BER performance below standard FEC threshold (2 - 10 -3 ) in a field-link transmission with 112 Gbit/s over 42 km standard single-mode fibre.

The meal as a performance : Food and meal practices beyond health and nutrition
- 2018

Journal article (peer-reviewed)abstract
- The proportion of elderly people in the population is increasing, presenting a number of new challenges in society. The purpose of this qualitative study was to investigate how elderly persons with motoric eating difficulties perceive and perform their food and meal practices in everyday life. By using Goffman's concept of performance as a theoretical framework together with Bourdieu's thinking on habitus, a deeper understanding of food and meal practices is obtained. Semi-structured interviews were conducted with 14 elderly people (aged between 67 and 87 years) and meal observations were carried out with 11 of these people. Participants were found to manage food and meal practices by continuously adjusting and adapting to the new conditions arising as a result of eating difficulties. This was displayed by conscious planning of what to eat and when, avoiding certain foods and beverages, using simple eating aids, but also withdrawing socially during the meals. All these adjustments were important in order to be able to demonstrate proper food and meal behaviour, to maintain the facąde and to act according to the perceived norms. As well as being a pleasurable event, food and meals were also perceived in terms of being important for maintaining health and as 'fuel' where the main purpose is to sustain life. This was strongly connected to the social context and the ability to enjoy food and meals with family members and friends, which appeared to be particularly crucial due to the impending risk of failing the meal performance.

106.25 Gbaud On-Off Keying and Pulse Amplitude Modulation Links Supporting Next Generation Ethernet on Single Lambda
- 2024
-
In: Journal of Lightwave Technology. - 0733-8724 .- 1558-2213. ; 42:4, s. 1272-
-
Journal article (peer-reviewed)abstract
- Development of Data Center based computing technology require energy efficient high-speed transmission links. This leads to optical amplification-free intensity modulation and direct detection (IM/DD) systems with low complexity equalization compliant with IEEE standardized electrical interfaces. Switching from on-off keying to multi-level pulse amplitude modulation would allow to reduce lane count for next generation Ethernet interfaces. We characterize 106.25 Gbaud on-off keying, 4-level and 6-level pulse amplitude modulation links using two integrated transmitters: O-band directly modulated laser and C-band externally modulated laser. Simple feed forward or decision feedback equalizer is used. We demonstrate 106.25 Gbaud on-off keying links operating without forward error correction for both transmitters. We also show 106.25 Gbaud 4-level and 6-level pulse amplitude modulation links with performance below 6.25% overhead hard-decision forward error threshold of 4.5×10-3. Furthermore, for EML-based transmitter we achieve 106.25 Gbaud 4-level pulse amplitude modulation performance below KP-FEC threshold of 2.2×10-4. That shows that we can use optics to support (2x)100 Gbps Ethernet on single lambda at expense of simple forward error correction.

Conference paper (peer-reviewed)abstract
- We demonstrate an error-free 108 Gbps OOK link using a C-band externally modulated laser with 3.3 dBm of modulated output power and an O-band directly modulated laser with 7.3 dBm of modulated output power. This paves the way forward for high-speed optical interconnects without FEC.
