Methodological Proposal for the Assessment Potential of Pumped Hydropower Energy Storage: Case of Gran Canaria Island

The pumped hydropower energy storage (PHES) assessments carried out so far have been focused on large water bodies obtained from global or restricted-use databases, or, on the other hand, on the application of methodologies to specific areas focusing on the detection of dams. In addition, many assessments do not include data optimization, or include it at the end of the process and are subject to the prior application of restrictions, often stipulated with subjective criteria. The aim of this article is to design a universal and easily applicable methodology for the assessment of viable PHES potential, which provides immediate and reliable results to assist in the energy planning of a given territory. It is classified in ravine basins, including an optimization before using the restrictions. The island of Gran Canaria is taken as the territory of application, whose density of dams is the highest in the world and whose share of hydroelectric energy is, at present, null; besides, no PHES studies have been carried out. The results show that the PHES potential in Gran Canaria is 5996 MWh after applying the optimization and all technical constraints. If all environmental constraints were rigorously applied, the island would have no possible pairing. The results demonstrate the importance of tailoring the restrictions to each particular territory.

Nasal Aesthetic Evaluation Following Pre-Surgical Naso-Alveolar Molding Application: A Single-Blinded Cohort Retrospective Study in Indonesia

Introduction: As a major facial aesthetic unit, the nose is one of the significant features in cleft lip and palate repair. The use of a naso-alveolar molding (NAM) device was known to help narrow the cleft gap and improve nasal aesthetics. This study aims to evaluate post-operative nasal morphology in unilateral cleft lip and palate patients who had used presurgical NAM, particularly in an established craniofacial centre in one of developing countries. Methods: A cohort retrospective study was conducted at Cleft Craniofacial Centre, Cipto Mangunkusumo Hospital Indonesia, comparing the nasal symmetry in unilateral cleft lip patients with and without prior application of NAM (NAM and control group), twelve months following primary cheiloplasty. Differences between the cleft and normal side were assessed using standard basilar view photographs based on five points nasal measurements. Results: A total of twelve patients were enrolled, six with a history of NAM application and six without (control). Overall nasal measurements confirmed a lower mean of differences in the NAM group compared to the control, showing statistically significant results in nostril height, nasal dome height, and columellar height (p <0.05). Conclusion: This study provides an insight that cleft lip patients with a history of NAM application had superior nasal symmetry compared to patients without presurgical NAM application 1-year post-cheiloplasty. Presurgical NAM application is recommended for patients with unilateral cleft lip and palate.

B-Learning and Technology: Enablers for University Education Resilience. An Experience Case under COVID-19 in Spain

Innovative teaching methodologies begat blended learning, which seems to facilitate engineering students’ achievement of competencies required for the 21st century and has proven to be essential to keep quality standards as university education has suffered the COVID-19 pandemic. In this paper, we approach the use of b-learning and digital technologies before the pandemic started, and how it worked like a vaccine, enabling university education resilience and facilitating the sustainability of the students learning process. A questionnaire-based study is presented, in which the data came from Aerospace Engineering students following a Mathematics subject in a Technological University in Spain. ANOVA and ANCOVA analysis provided a significant difference in the appreciation of the adaptation based on the prior application of b-learning methodologies or more traditional methodologies. Results obtained indicated that the use of digital resources and educational platforms caused a noticeable change in the students’ way of learning, improving habits and digital skills.

Nursing Team Training to Use a Flowchart to Care for Patients with Chest Pain

Background: chest pain, of multicausal etiology, associated with a cardiac cause or not, is one of the most frequently presented symptoms by patients in Emergency Care Units. Despite its high prevalence in health services, there is still a deficiency in care standardization, which raises difficulties in acute coronary syndrome diagnosis and delay in treatment. The objective was to assess the efficiency of professional training of nursing teams in Emergency Care Units on the use of a flowchart to care for patients with chest pain. Methods and Findings: this educational intervention study was conducted with 25 nursing team professionals. It has been developed in four steps: Step 1 referred to prior application of the validated research instrument. Step 2 comprised training to use the flowchart with an expository lesson on care of patients with chest pain and guidance regarding the flowchart to be implemented. Step 3 reapplied the validated instrument after class. Step 4 reapplied the instrument after 2 months of training for flowchart implementation. When comparing the results of the instrument applied to nursing team professionals, post-training and follow-up performance surpassed that of pre-training. It was observed that professionals with less than five years of experience showed better performance. This study had as limitation the small sample of health professionals participating in the offered training. Conclusion: training was satisfactory and significant, and professionals demonstrated content assimilation, obtaining higher scores than at the beginning of the research.

Frey's Syndrome

Frey's syndrome is secondary to sympathetic denervation of sweat glands – reinnervation through the auriculotemporal nerve is a secondary event. The aberrant regeneration theory explains the physiopathology of Frey's syndrome. Frey's syndrome incidence after parotidectomy, without prevention techniques, is 40-80% by clinical questioning and 80–100% by objective testing. It occurs months to years after surgery. A topographic and quantitative testing for Frey's is required prior to its treatment – the iodine-sublimated paper histogram (ISPH) test has the majority of desired features. Intradermic botulinum toxin injection is a well-tolerated and efficient treatment. The recommended dilution is 50 IU/1 ml, inter-injection distance is 1 cm, and injection volume is 0.1 ml. Complications to avoid include (1) facial muscle paralysis (rare and reversible complication; inject only intradermally and avoid injecting toward the midline) and (2) pain during injection (if bothersome could be decreased by the prior application of topical anesthetic cream).

The Dialogue between the Supreme Administrative Court and the Constitutional Tribunal in the Preliminary Reference Procedure

The purpose of the article is to analyze how the Supreme Administrative Court implements the right of this court to apply to the Constitutional Tribunal, enshrined in the Constitution of the Republic of Poland, with a request to examine the constitutionality of the legal act applicable in a particular case. The emergence of this investigation is marked by a noticeable decrease in the number of requests submitted by administrative courts to investigate the constitutionality of a legal act, which encourages the investigation of the causes of this phenomenon. The prior application of the court for the constitutionality of a legal act encourages the analysis of a specific cooperation dialogue between the requesting court and the Constitutional Tribunal.

Pre-validation of a MALDI MS proteomics-based method for the reliable detection of blood and blood provenance

The reliable identification of blood, as well as the determination of its origin (human or animal) is of great importance in a forensic investigation. Whilst presumptive tests are rapid and deployed in situ, their very nature requires confirmatory tests to be performed remotely. However, only serological tests can determine blood provenance. The present study improves on a previously devised Matrix Assisted Laser Desorption Ionisation Mass Spectrometry (MALDI MS)—proteomics based method for the reliable detection of blood by enabling the determination of blood provenance. The overall protocol was developed to be more specific than presumptive tests and faster/easier than the gold standard liquid chromatography (LC) MS/MS analysis. This is considered a pre-validation study that has investigated stains and fingermarks made in blood, other biofluids and substances that can elicit a false-positive response to colorimetric or presumptive tests, in a blind fashion. Stains and marks were either untreated or enhanced with a range of presumptive tests. Human and animal blood were correctly discriminated from other biofluids and non-biofluid related matrices; animal species determination was also possible within the system investigated. The procedure is compatible with the prior application of presumptive tests. The refined strategy resulting from iterative improvements through a trial and error study of 56 samples was applied to a final set of 13 blind samples. This final study yielded 12/13 correct identifications with the 13th sample being correctly identified as animal blood but with no species attribution. This body of work will contribute towards the validation of MALDI MS based methods and deployment in violent crimes involving bloodshed.

MOVIE RECOMMENDATION USING KNOWLEDGE GRAPH

The Knowledge graphs (KGs) catches structured data and relationships among a bunch of entities and items. Generally, constitute an attractive origin of information that can advance the recommender systems. But, present methodologies of this area depend on manual element thus don’t permit for start to end training. This article proposes, Knowledge Graph along with Label Smoothness (KG-LS) to offer better suggestions for the recommender Systems. Our methodology processes user-specific entities by prior application of a function capability that recognizes key KG-relationships for a specific user. In this manner, we change the KG in a specific-user weighted graph followed by application of a graph neural network to process customized entity embedding. To give better preliminary predisposition, label smoothness comes into picture, which places items in the KG which probably going to have identical user significant names/scores. Use of, label smoothness gives regularization above the edge weights thus; we demonstrate that it is comparable to a label propagation plan on the graph. Additionally building-up a productive usage that symbolizes solid adaptability concerning the size of knowledge graph. Experimentation on 4 datasets shows that our strategy beats best in class baselines. This process likewise accomplishes solid execution in cold start situations where user-entity communications remain meager.
