This article concerns presentation and comparison of the performance of a set of the Internet Of Things protocols in the application layer and others that are used to link objects such as: Message ...Queuing Telemetry Transport (MQTT), Constrained Application Protocol (COAP), Extensible Messaging and Presence Protocol (EMPP), RESTFUL Services, Advanced Message Queuing Protocol (AMQP), and Websockets. This comparison will be carried out in terms of security, transport, architecture and quality of service (QoS). This work will enable us to specify the strong and weak points of each protocol.
Salinity constrains the development and yield of valuable aromatic and medicinal plants, including fenugreek (
Trigonella foenum-graecum
L.). Silicon (Si) is a promising strategy for managing salt ...stress. However, knowledge related to the effects of Si-seed priming on growth and yield of salt-stressed fenugreek under natural conditions are scarce. Hence, the present work aimed to investigate whether Si-seed priming (0–60 mM CaSiO
3
) could help to improve the performance of fenugreek when subjected to salt stress (100 and 150 mM NaCl). Findings show that salt stress significantly reduced germination related parameters and triggered an oxidative stress in fenugreek seedlings. However, Si priming was found to be effective in attenuating oxidative stress and enhancing germination parameters under salt stress. Indeed, the most pronounced effect was observed in primed seed with 20 mM Si. This concentration was then selected to assess the effect of Si priming on growth and yield in salt-stressed fenugreek grown under natural conditions. Si priming significantly enhanced plant biomass and yield-related parameters in salt-stressed plants as relative to non-primed plants. Interestingly, the biochemical characterization of harvested seeds revealed that Si priming not only improved growth and yield attributes but also enhanced the nutritional quality and antioxidant activity in harvested seed from salt-stressed plants. In summary, the results of this study provide compelling evidence that, as a promising and eco-friendly approach, Si-based seed priming mitigates the adverse effects of salinity on fenugreek growth and yield under natural conditions.
Observations of the synchronous double asteroid (3905) Doppler were carried out during a campaign of 3 months between October 2017 and December 2017. Several eclipse events of 0.2–0.3 mag were ...recorded. We refined the rotational period to 50.826 ± 0.002 h. The J2000 ecliptic coordinates of the pole of the system are: λ = 215 ± 2° and β = 65 ± 2°.
The observed light curves have been reproduced synthetically by modeling each member of the system as an elongated ellipsoid, separated from each other by a distance equivalent to 5 times the sum of the two diameters. Assuming an identical internal composition of each component, we derived a bulk density of 3.8 ± 0.2 g/cm3. Such a high density is typical of M-type asteroids.
Introduction
Based on European guidelines, transcatheter aortic valve implementation (TAVI) could be the therapy of choice in patients with severe aortic stenosis aged ≥ 75 years. In the Netherlands, ...there has been a debate between healthcare providers and the National Health Care Institute regarding reimbursement for TAVI, which resulted in an indication document that defines TAVI patients who are eligible for reimbursement. This document has been effective since 1 January 2021.
Methods
We extracted data from the Netherlands Heart Registry for patients who underwent biological surgical aortic valve replacement (SAVR) or TAVI in the Netherlands from 2018 through 2021. We compared baseline characteristics and variables from the indication document for the subsequent years and age groups. We also analysed the annual SAVR/TAVI ratio.
Results
The total number of patients treated with SAVR or TAVI was constant in 2018–2021. Baseline characteristics of patients treated with TAVI did not differ throughout the years. The SAVR/TAVI ratio shifted towards a higher percentage of TAVI from 2018 to 2019. From 2019 to 2020, the TAVI percentage was constant. Since the implementation of the indication document (in 2021), a change in the SAVR/TAVI ratio was not found either.
Conclusion
Since the implementation of the national indication document for AVR in 2021, no major effect was seen for the SAVR versus TAVI landscape in the Netherlands.
