Smart meters and water leakage detection : A preliminary study
- 2019
-
In: I2MTC 2019 Proceedings. - 9781538634608
-
Conference paper (peer-reviewed)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.

Effects of climate change and maternal morality : Perspective from case studies in the rural area of Bangladesh
- 2019
-
In: International Journal of Environmental Research and Public Health. - : MDPI AG. - 1661-7827 .- 1660-4601. ; 16:23
-
Journal article (peer-reviewed)abstract
- This study explored the community perception of maternal deaths influenced by natural disaster (flood), and the practice of maternal complications during natural disaster among the rural population in Bangladesh. It also explored the challenges faced by the community for providing healthcare and referring the pregnant women experiencing complications during flood disaster. Three focus group discussions (FGDs) and eight in-depth interviews (IDIs) were conducted in the marginalized rural communities in the flood-prone Khaliajhuri sub-district, Netrakona district, Bangladesh. Flood is one of the major risk factors for influencing maternal death. Pregnant women seriously suffer from maternal complications, lack of antenatal checkup, and lack of doctors during flooding. During the time of delivery, it is difficult to find a skilled attendant, and referring the patient with delivery complications to the healthcare facility. Boats are the only mode of transport. The majority of maternal deaths occur on the boats during transfer from the community to the hospital. Rural people feel that the maternal deaths influenced by natural disaster are natural phenomena. Pre-preparation is needed to support pregnant women during disasters. There is unawareness of maternal health, related care, and complications during disasters among local health service providers and volunteers.

Enamine/Transition Metal Combined Catalysis : Catalytic Transformations Involving Organometallic Electrophilic Intermediates
- 2019
-
In: Topics in current chemistry. - : Springer Science and Business Media LLC. - 0340-1022 .- 1436-5049 .- 2365-0869 .- 2364-8961. ; 377:6
-
Journal article (peer-reviewed)abstract
- The concept of merging enamine activation catalysis with transition metal catalysis is an important strategy, which allows for selective chemical transformations not accessible without this combination. The amine catalyst activates the carbonyl compounds through the formation of a reactive nucleophilic enamine intermediate and, in parallel, the transition metal activates a wide range of functionalities such as allylic substrates through the formation of reactive electrophilic π-allyl-metal complex. Since the first report of this strategy in 2006, considerable effort has been devoted to the successful advancement of this technology. In this chapter, these findings are highlighted and discussed.

Synthesis of amides and amines from aldehydes or ketones by heterogeneous metal catalysis
- 2019
-
Patent (pop. science, debate, etc.)abstract
- A mild and efficient synthesis of primary amines and amides from aldehydes or ketones using a heterogeneous metal catalyst and amine donor is disclosed. The initial heterogeneous metal-catalyzed reaction between the carbonyl and the amine donor components is followed by the addition of a suitable acylating agent component in one-pot, thus providing a catalytic one-pot three-component synthesis of amides. Integration of enzyme catalysis allows for eco-friendly one-pot co-catalytic synthesis of amides from aldehyde and ketone substrates, respectively. The process can be applied to asymmetric synthesis or to the co-catalytic one-pot three-component synthesis of capsaicin and its analogues from vanillin or vanillyl alcohol. A co-catalytic reductive amination/dynamic kinetic resolution (dkr) relay sequence for the asymmetric synthesis of optically active amides from ketones is disclosed. Implementation of a catalytic reductive amination/kinetic resolution (kr) relay sequence produces the corresponding optically active amide product and optical active primary amine product with the opposite stereochemistry from the starting ketones.

The Chemical Synthesis and Applications of Tropane Alkaloids
- 2019
-
In: Alkaloids: Chemistry and Biology. - : Elsevier. - 1099-4831. ; 81, s. 151-233
-
Journal article (peer-reviewed)abstract
- Tropanes are an important class of alkaloid natural products that are found in plants all over the world. These compounds can exhibit significant biological activity and are among the oldest known medicines. In the early 19th century, tropanes were isolated, characterized, and synthesized by notable chemical researchers. Their significant biological activities have inspired tremendous research efforts toward their synthesis and the elucidation of their pharmacological activity both in academia and in industry. In this chapter, which addresses the developments in this field since 1994, the focus is on the synthesis of these compounds, and several examples of sophisticated synthetic protocols involving both asymmetric and catalytic approaches are described. In addition, the structures of more than 100 new alkaloids are included as well as the applications and pharmacological properties of some tropane alkaloids.

Determining Testbed Requirements for Technology Enhanced Speech Rehabilitation after Stroke -the Informed Co-workers’ View Point
- 2019
-
In: GLOBAL HEALTH 2019. - : International Academy, Research and Industry Association (IARIA). - 9781612087429 ; , s. 20-27
-
Conference paper (peer-reviewed)abstract
- This paper analyses and discusses the identified requirements for technology enhanced systems for speech rehabilitation after a stroke. To stroke patients, a speech injury can be devastating, impacting their abilities to speak, listen, read, and write. Therefore, speech therapy is recommended as early as possible. To address the challenge with a growing percentage of older adults, therapy should include a variety of Technology Enhanced Systems (TES) to support the idea of independent living. These systems must be adapted to the patients’ needs and speech therapy requirements. Based on a design science approach, requirements were determined from an analysis of ten semi-structured interviews with knowledgeable informants. Findings indicate several important requirements, such as: TES should be motivating, joyful, individualised and built on patients’ needs and on speech therapists’ professional knowledge. Furthermore, TES services must be user-friendly and provide training in each patient’s mother tongue. Added to these requirements are ease of including close relatives as supporting persons, as well as accessibility through portable devices.

Measuring the Immeasurable? : The Intangible Benefits of Digital Information
- 2019
-
In: Proceedings of the 52nd Hawaii International Conference on System Sciences 2019. - : Hawaii International Conference on System Sciences. - 9780998133126 ; , s. 6176-6185
-
Conference paper (peer-reviewed)abstract
- The benefits of digital information are mostly viewed as intangible, meaning that they can be hard to measure. This lack of measurements makes the benefits difficult to compare and communicate, creating problems for e.g. decision-making and the strategic development of specific digital information. Therefore, I conducted a literature review to find out how the combination of intangible benefits and measurements are dealt with in the information systems field. I found that we measure the intangible benefits of information systems or information technology. Here, the measurement method is divided into input, rule, and output. The input consists of predetermined individual benefits, areas of predetermined benefits, or interpreted benefits from respondents. The rule follows an accepted theory or contextual adjusted rules, and the output (benefit) can be seen as either financial or non-financial. The avenue for further research focuses on the digital information as the primary resource, not information systems or information technology.

Critical Factors for Human Computer Interaction of eHealth for Older Adult
- 2019
-
In: Proceedings of the 2019 the 5th International Conference on e-Society, e-Learning and e-Technologies. - Vienna : Association for Computing Machinery (ACM). - 9781450362351 ; , s. 58-62
-
Conference paper (peer-reviewed)abstract
- The percentage of older adults increases globally with an increased need for medical care. To support the idea of successful active aging, e-health seems to be an interesting concept. This study was conducted as a systematic literature study, with the aim to identify and discuss determinant factors in the Human computer interaction of eHealth for older adults. The important main research question to answer was: What are the critical challenges to address for an improved human computer interaction in technology enhanced health care systems for older adults? Findings show that there are several critical factors to consider, with trust, personal integrity, technological acceptance, e-health literacy and accessibility of ICT as the most determinant. If the found challenges are addressed, it might be possible to achieve the identified aim of independent living. The recommendation is a human computer interaction that is elderly centred, and involves the elderly users in the design process. However, no ICT enhanced system will be user-friendly enough to take away the need for social and technological support.

Testbed requirements for technology enhanced stroke rehabilitation to support independent living
- 2019
-
In: ICT4AWE 2019 - Proceedings of the 5th International Conference on Information and Communication Technologies for Ageing Well and e-Health. - : SCITEPRESS - Science and Technology Publications. ; , s. 174-182

Conference paper (peer-reviewed)abstract
- An identified global phenomenon is that, as the percentage of older adults increases, new challenges arise for medical care and rehabilitation. Several research studies have presented e-health as a promising concept to support the idea of independent living among patients with chronic diseases. The Mid Sweden region has a relatively old population and is a region where people live with long distances to the nearest hospital or health care centres. This study had a focus on defining testbed requirements for a technology enhanced stroke rehabilitation adapted to the specific region. The focal research question to answer in this study was: What are the requirements and their associated benefits and barriers of using technology-enhanced systems instead of traditional techniques for stroke rehabilitation in the Mid Sweden region? With Design Science as the overall research strategy, data was collected by semi-structured interviews with key stakeholders in the field of stroke rehabilitation. A deductive thematic analysis was conducted where important themes were grouped into the four main requirement categories of: Technical, Human-computer-interaction, Clinic and Sustainability. Beside the more specific requirements, an interesting finding was the division of stroke rehabilitation into the categories motoric, cognitive and speech rehabilitation; also, how technology enhanced solutions might be used in these categories. Each category has a potential for a successful use of technology enhanced services, but as the standard procedure in traditional stroke rehabilitation each patient needs a personalised treatment.
