Dynamic Corrosion of Carbonate Salt for 3rd Generation CSP Plants
Authors: González-Fernández Luis , Intxaurtieta Carcedo Mikel , Bondarchuk Oleksandr , Grosu Yaroslav 
Published: March 2024

Eutectic ternary carbonate salt is one of the candidates for 3rd generation concentrated solar power (CSP) plants. Gen3 CSP targets higher operation temperatures, which strengthens the corrosivity issues associated to molten salts. Although there are corrosion studies for this carbonate salt in static conditions, the effect of salt flow is not fully understood. In this work, corrosion experiments under static and dynamic conditions are compared for SS310 subjected to ternary carbonate salt at 600ºC.
The corrosion layer formed during static and dynamic tests were completely characterized by means of SEM-EDX and XRD (surface and cross-section). The corrosion products deposited in the salt during the experiment were analyzed by ICP-OES.
The tests performed under dynamic conditions demonstrated an increase spallation of the corrosion layer. This spallation produced a thinner scale and exposed the Cr containing phase to the molten salt, fostering its dissolution. These results confirmed the significant effect of dynamic conditions on the corrosivity of eutectic ternary carbonate salt and the importance of assessing them in the design of 3rd generation CSP plants.
Modelling of Solar Thermal Electricity Plants in the POSYTYF Research Project for an Extensive Integration of Renewable Energy Sources

Published: March 2024

This article presents a simplified simulation model of a concentrated solar thermal power plant developed in the framework of the European research project POSYTYF (POwering SYstem flexibiliTY in the Future through RES). Increasing the share of Renewable Energy Sources (RES) in modern power grids is of critical importance for the transformation of the energy markets worldwide. However, the stability of the grid and the limited participation in ancillary services of RES limit their use, especially when high penetration is expected from them. A solution to overcome these issues is to increase the share of so-called dispatchable RES (hydropower, biomass, concentrating solar thermal power). The main objective of the POSYTYF project is to group several renewable and non-renewable energy sources into a Dynamic Virtual Power Plant (DVPP). The simplified simulation model of a parabolic-trough solar thermal power plant developed consists of sub-models for the solar field, thermal energy storage system and power block and it has been validated with real DNI profiles and production data of a commercial STE plant in Spain. The differences between the simulation and real data of daily net production for the days analysed are lower than 1%.

Published: March 2024

Implementing the ideological and political reform is an important initiative of the current ideological and political work in colleges. As one of the core courses for English majors, Comprehensive English course is an important starting point for the ideological and political construction of English majors. The "production-oriented approach" is a localized foreign language teaching theory proposed by Professor Wen Qiufang, which is suitable for China's national situation. In the context of the comprehensive implementation of ideological and political education in today's curriculum, the production-oriented approach is used as a theoretical guide to demonstrate the teaching process of the comprehensive English course according to the three links of "Motivating-Enabling-Assessing", taking a unit in the comprehensive English textbook as an example. The three links demonstrate the teaching process, integrating knowledge transfer and ideological education, in order to provide reference for other courses to deepen their educational teaching reform.

Purpose: This study aims to provide valuable insights for stakeholders in Puerto Nariño, Amazonas enabling them to develop strategies tailored to their needs. Particularly, it assessed the sustainability of indigenous tourism initiatives in the municipality of Puerto Nariño, Amazonas.
Design/Methodology/Approach: This qualitative study involved pioneering indigenous family tourism initiatives and a sustainability framework with a set of 12 sustainability indicators to explore the perceptions of tourism service providers. Convenience sampling was used to collect data through questionnaires.
Findings: According to the findings, families are aware of the advantages of tourist activities with the culture-society component having the highest average score (3.13/5.00). However, it can be inferred that factors encompassing economic, governance and environmental dimensions such as employment and income generation (average 2.00/5.00), encouragement and convening spaces to promote participatory community decision-making mechanisms (average 1.75/5.00), reliable energy supply and enhancing knowledge of local wildlife, vegetation and sporting activities (average 1.70/5.00) remain critical in this indigenous context. Additionally, the initiative's governance component has been evaluated as having the lowest average (2.19/5.00).
Practical Implications: These findings contribute to the existing body of knowledge on ecotourism practices in indigenous settings particularly in South American ethnic communities.
Contribution to the Literature: These findings offer valuable insights for institutions seeking a deeper understanding of tourism practices within protected areas.

Flow of MHD micropolar fluid through porous medium: a hodograhic approach for exact solution
Authors: Sil Sayantan 
Published: March 2024

An analytical study of the motion of a steady, homogenous, incompressible, plane electrically conducting micropolar fluid flow through a porous medium subjected to a transverse magnetic field is carried out. The governing non linear partial differential equations describing the continuity, momentum and angular momentum are converted into a system of linear partial differential equations by means of hodograph transformation. Further the flow equations have been obtained in terms of Legendre transform function of the stream function. Results are summarized in the form of a theorem. Lastly two examples have been taken as application to illustrate the developed theory and exact solutions are determined. The expressions for velocity, micro-rotation, streamline and pressure distribution are obtained in each case. The streamline patterns are plotted and also the pressure variation with x and y are studied for varying porous media parameter at constant density of fluid and also for varying density of different fluids at constant porous media parameter value.

Hypoglycemia in the Hospitalized Patient: Interventions and Opportunities
Authors: Giroir Chelsea , Calmes Helen 
Published: March 2024

Hypoglycemia occurs frequently in hospitalized patients and can lead to cardiac arrhythmia/ischemia, seizures, or death. The Louisiana Hospital Improvement Innovation Network (HIIN) requires hospitals to report incidents of hypoglycemia as a quality measure. The purpose of this study is to evaluate the incidence of hypoglycemic events and identify precipitating factors at our institution. This is an IRB-approved single-center, retrospective chart review conducted from January to December of 2022 at an academic medical center. All admitted patients who received an antihyperglycemic agent and experienced a hypoglycemic event, defined as blood glucose <50 mg/dL (2.8 mmol/L), within 24 hours were included. The primary outcome assessed the incidence of hypoglycemic events. A total of 2455 patients received insulin during their admission, of which 91 (3.7%) had a hypoglycemic event that met inclusion criteria. Patients were predominately male (58%) with a median age of 53 years old. A diagnosis of Type I or Type II Diabetes Mellitus was reported in 73% of patients. Basal or basal-bolus insulin was ordered in 70.3% of patients. Our institution’s yearly incidence of 3.7% is above the HIIN standard of 3%. Optimization of guidelines and order sets are proposed to help lower the incidence of hypoglycemic events.

Optical wireless communication (OWC) is a strong candidate in the sixth generation (6G) of wireless communications as it can support data transmission at high communication speeds, low power consumption, high security, and high reliability. Near-infrared lasers, specifically vertical cavity surface emitting lasers (VCSELs), exhibit larger modulation bandwidth compared to light-emitting diodes (LEDs), and can provide aggregate data rates ranging up to Terabit per second (Tbps). This chapter proposes innovative optical transmitter and receiver designs for indoor laser-based wireless communications, aiming to provide seamless coverage in high-speed multi-user scenarios. The proposed optical transmitter is based on a 5 × 5 VCSEL array where each VCSEL can provide 10 Gigabit per second (Gbps) in a uniform coverage area of 20 cm x 20 cm, achieving a total of 250 Gbps in an area of 1 m2 at 3 m transmission distance. Moreover, two wide-FOV receiver designs that employ photodetector (PD) arrays in along with imaging or non-imaging optics are introduced to support such an ultra-high-speed optical link. The new design of OWC requires potential techniques to address various networking challenges, including cell formation, interference management, resource allocation, and backhauling. To this end, potential solutions for these challenges are discussed to help establish an end-to-end OWC infrastructure for practical deployment.

VA-ECMO (veno-arterial extracorporeal membrane oxygenation) is mostly indicated for cardiogenic shock caused by myocardial infarction or other causes. However, it is also indicated for shocks caused by other factors and cardiovascular diseases. In fact, VA-ECMO may be very useful as an adjunctive treatment for drug-induced cardiogenic shock until the drug effect wears off. We have experienced a case of bradyarrhythmia and cardiopulmonary arrest due to high-dose carbamazepine ingestion, and VA-ECMO was introduced to save the patient’s life. The patient was a female in her 50s with a history of schizophrenia. On the day of admission, the patient’s family found her collapsed at home after she had taken an overdose of carbamazepine, and they called an ambulance. Upon arrival at the hospital, the patient’s bradycardia progressed to cardiac arrest. Her heartbeat resumed, but we observed drug-resistant bradycardia, so we introduced VA-ECMO. The patient was weaned from VA-ECMO on the fourth day of hospitalization and from the ventilator on the tenth day. She was discharged after 35 days. Carbamazepine is a sodium channel blocker with proarrhythmic effects. Because bradyarrhythmia during overdose is refractory to treatment, it is suggested that VA-ECMO is effective in cases of circulatory failure or cardiac arrest.
Exercise Is Medicine through Time: Prescription of Adapted Physical Activity in Treatment and Rehabilitation
Authors: Asonitou Katerina , Yiannaki Soteria , Koutsouki Dimitra 
Published: March 2024

The history of physical activity and sport dates to ancient times, when it was not only a means of preparation for military readiness but also had religious and educational purposes. The relationship between physical activity and good health goes back centuries accepted, as formulated by Hippocrates 2500 years ago. In Greek antiquity, “gymnastike” highlighted physical beauty in harmony with the soul and spirit, perfecting simultaneously an individual’s personality and health. Lifelong exercise administered by gymnasts was applied to strengthen weak limbs, and contributed to the healing of patients when applied in the healthcare facilities of the time, as mentioned in “Asclepieia.” Nowadays, the idea that “exercise is medicine” has two components: (1) every patient’s treatment or rehabilitation plan should include physical activity and exercise training, but the prescription must be tailored to the patient’s specific needs and (2) doctors’ challenge lies in implementing this medical prescription for adapted physical activity (APA), which encourages patients to lead more active lives.
