    This study aimed at investigating the effect of oat composition on the quality characteristics of oat-based milk substitute (OBMS). Raw materials for OBMS consisted of thirty pure cultivar oat flours produced by industrial milling process. The main steps in OBMS preparation included mixing of 10% oat flour with water, starch hydrolysis, solid-liquid separation and formulation of the final product. OBMS was characterised in terms of mass and protein yields, protein content, reducing sugars, particle size, viscosity, dispersion stability and colour. The different composition of oat flours affected the characteristics of the OBMS in terms of mass yield (81.3–88.1%), dry matter yield (56.7–73.8%), protein content (0.63–1.10%), protein yield (31.4–61.6%), content of free reducing sugars (13.1–19.1%), and physical properties including particle size, dispersion stability and viscosity. OBMS mass and dry matter yields correlated positively with both total and damaged starch contents of the oat flour as well as the share of damaged starch of the total starch of the sample, while flour starch content correlated negatively with protein content of OBMS. Protein content of the flour correlated negatively with the mass, dry matter and protein yields and positively with protein content of OBMS. All colour values (L*, a*, b*) of the flour correlated with colour value b* of the OBMS. Protein content and viscosity of OBMS correlated positively with dispersion stability of OBSM. In conclusion, the clear relation between oat composition and the final properties of OBMS suggest relevance of selecting specific oat raw materials to produce good quality OBMS

    The Modular Infrared Molecules And Ices Sensor (MIRMIS): An Instrument Visiting A Long-Period Comet

    The Comet Interceptor mission, selected in 2019, is an ESA’s first F-class mission. It will be the first to visit a (yet-undiscovered) long-period comet or interstellar object. These objects are expected to be “pristine” having not been exposed to the Sun in the inner Solar System. A long-period comet may therefore preserve some of the most primitive material from the early solar system’s history. The mission will launch 3 spacecraft (main spacecraft A and 2 probes: B1 and B2) to the L2 Earth-Sun Lagrange point in which it will wait for a suitable target. The MIRMIS spectrometer is one of the instruments on board of Comet Interceptor mission. It is a collaboration between University of Oxford (UK) and VTT (Finland) as well as scientists from the University of Helsinki, NASA’s Goddard Space Flight Centre, University of Lyon and Southwest Research Institute. The instrument will map the ice and mineral composition of the target nucleus, it will provide characterisation of the gas coma, as well as the distribution of the surface temperatures of the comet nucleus. The spectrometer is composed of 3 moduels covering the spectral range of 0.9 to 25 µm. The Near and Mid Infrared modules (NIR/MIR) will measure spectra in the 0.9 to 5 µm, providing information on volatile species, such as water, CO, CO2 and organics. The Thermal Infrared Imager (TIRI), built at University of Oxford, will map the temperature and composition of the nucleus in the range of 6 to 25 µm, providing key information on the surface and near sub-surface thermal physical properties (e.g. cold traps, boulders/powdered regolith). The AOGS 2024 conference will be an opportunity to present the latest with the design and development of MIRMIS

    Evaluation of Printed Coplanar Capacitive Sensors for Reliable Quantification of Fluids in Adult Diaper

    Advancements in printed technology have led to the development of economical and sustainable electronic solutions for wearable medical devices in the healthcare sector. Printed capacitive sensors in planar geometry are widely used in the development of smart diapers for detecting urination events, quantifying detection, and quantifying voided volumes. However, factors such as the effect of sodium electrolyte variation, body weight effect on a wet diaper and gravitational effect on wet diapers impair the quantification of voided volume with capacitive sensors. In this study, a printed capacitive sensor for quantifying human body fluids in adult diaper was evaluated to analyze these effects. Silver and carbon inks were used to print the parallel-plate capacitive electrodes on a flexible substrate in a coplanar geometry. In-diaper quantification measurements were performed at various concentration levels in pseudo urine with small incremental levels at the adult human urination flow rate. The impact of human body weight on quantification measurements using a wet diaper was studied. The gravitational pull effect of wetness was evaluated for on-human-torso use in both standing and lying positions. It was observed that a printed coplanar capacitive sensor alone is insufficient to reliably quantify the voided volume in diapers.</p

    Challenges and needs in cerebrovascular disease pathway:A qualitative descriptive study from the patients' and healthcare professionals' perspectives

    No full text
    Aim(s): To understand patients' and healthcare professionals' experiences to improve care in and across different domains of the cerebrovascular disease pathway. Design: A qualitative descriptive study. Methods: Semi-structured in-person interviews were conducted among 22 patients diagnosed with acute cerebrovascular disease and 26 healthcare professionals taking care of them in a single tertiary-level hospital from August 2021 to March 2022. Data were analysed using deductive and inductive content analysis. The consolidated criteria for reporting qualitative research was used to ensure reliable reporting. Results: Overall, 19 generic and 79 sub-categories describing perceived challenges with 17 generic and 62 sub-categories describing perceived needs were identified related to primary prevention, organization of stroke services, management of acute stroke, secondary prevention, rehabilitation, evaluation of stroke outcome and quality assessment, and life after stroke. Conclusion: Several challenges and needs were identified in and across the different domains of the cerebrovascular disease pathway. There is a requirement for adequate resources, early initiation of treatment, early diagnostics and recanalization, dedicated rehabilitation services, long-term counselling and support, and impact evaluation of services to improve cerebrovascular disease care. Future research on caregivers', and clinical leadership experiences in and across the cerebrovascular disease pathway is needed to explore the provision of services. Implications for the Profession and/or Patient Care: The results of this study can be applied by organizations, managers and research for developing and improving services in the cerebrovascular disease pathway. Impact: This study identified several patient-related, organizational and logistical needs and challenges, with suggestions for required actions, that can benefit the provision of effective, high-quality cerebrovascular disease care. Reporting Method: We have adhered to relevant EQUATOR guidelines with the COREQ reporting method. Patient or Public Contribution: No patient or public involvement.</p
