Published: November 2022

The sounds of our hands and feet on objects, materials and architecture itself, allow us a high knowledge of them if we have the precise sound education. For this reason, this workshop of touching architecture is proposed, where each participant must learn how to generate sounds, how to listen carefully, and how to interpret the results, concluding on the composition of the analyzed materials themselves, their isostatic or hypostatic union structures, the existing constructive pathologies (if applied to experts), etc. In short, applying something as old as “touching” and thereby observing how the different structures, pavements and cladding of architecture sound and resonate when touched, pinched or percussed.Los sonidos de nuestras manos y pies sobre los objetos, los materiales y la propia arquitectura, nos permiten un alto conocimiento de ellos si disponemos de la educación sonora precisa. Por ello se plantea este taller de tocar la arquitectura, donde cada participante debe aprender cómo generar los sonidos, cómo realizar la escucha atenta, y cómo interpretar los resultados, concluyendo sobre la composición de los propios materiales analizados, sus estructuras de unión isostática o hipetestática, las patologías constructivas existentes (caso de aplicarse a periciales), etc. En suma, aplicar algo tan antiguo como “tocar” y observar con ello cómo suenan y resuenan las diferentes estructuras, pavimentos y revestimientos de la arquitectura al ser tocada, pinzada o percutida.

Published: November 2022

The role of architects in urban design is quite unknown in society and the significance of architecture is relegated, in most cases, to the building. Fundamental aspects such as the width of the streets, the vegetation, the height of the buildings or the pavement seem alien to architecture. Even its impact on energy efficiency and user comfort, not only on public roads but also inside buildings, is often ignored. This idea of separation between architecture and efficient urban design is also that of those who start the degree in Architecture. Therefore, the objective of this teaching experience is to provoke a critical reflection of the students on these issues prior to the start of the degree, carrying out a workshop in the Zero Course in Architecture in which the active participation of the student is encouraged.
El papel de arquitectos y arquitectas en el diseño urbano es bastante desconocido en la sociedad y el alcance de la arquitectura queda relegado, en la mayoría de los casos, al edificio. Aspectos fundamentales como el ancho de las calles, la vegetación, la altura de los edificios o el pavimento parecen ajenos a la arquitectura. Incluso su repercusión en la eficiencia energética y el confort de los usuarios, no solo en la vía pública sino también en el interior de edificios, es ignorada en muchas ocasiones. Esta idea de separación entra arquitectura y diseño urbano eficiente es también la de aquellos que inician el grado en Arquitectura. Por tanto, el objetivo de esta experiencia docente es provocar una reflexión crítica del alumnado sobre estos temas previa al inicio del grado, realizando para ello un taller en el Curso Cero en Arquitectura en el que se fomenta una participación activa del estudiantado.

Effect of Skew on Stresses in Backing Fixed-Pitch Propellers
Authors: Luttmer B. R. I. , Hylarides S. 
Published: November 2022

Strength requirements on propellers in backing operations are hardly defined but they are found necessary for highly skewed propellers. The present paper illustrates how the MARIN design procedure copes with this aspect.
Relevant analysis conditions for backing operation and allowable stress levels are discussed. The relevance of strength calculations is demonstrated on the four propellers with systematically varied skew-back angles of 0, 30, 60, and 90 degrees. Finite element stress calculations lead to the conclusion that in backing operation the highest stresses occur at the trailing edge beyond the 0.8 radius and that the maximum stress varies almost linearly with the skew angle. Maximum astern power instead of the minimum required revolution rate, being 70% of the head value, could lead to such stress levels that tip bending happens.
For the derivation of the lift distribution use is the made of the lifting surface theory. Its applicability for backing operation is verified by comparing the calculated open water characteristics with measurements. Boundary layer observations by means of paint tests give information on the extent of separation. For the 90-degree skew propeller, this leads to behavior which is difficult to interpret and with unknown consequences for the detailed lift contribution.
Stress Analysis of Highly Skewed Propeller Blades Using the Finite Element Method
Authors: Sunnersjo C. S. 
Published: November 2022

The design of highly skewed propellers requires that special attention is given to the stress analysis of the blade. In this paper a number of Finite Element computer programs are applied to different element layouts on a highly skewed reference blade with uniform load. The calculated stresses are compared with measurements, the result of which shows that a certain care must be exercised for the choice of elements as well as node-pattern if the resulting accuracy is to be acceptable.
In order to simplify indata preparation a suite of existing programs giving propeller geometry, profile loading conditions and pressure distribution have been linked together and supplemented with a program that converts the output from these programs into a complete in data deck for a Finite Element Program. The program package produces plots and print-outs at a number of control stations during the process. The thus developed method for calculation of load and resulting stress distribution is applied to the SSPA skew propeller series. Stress distribution for forward and backing cases are studied as a function of skew angle, all other factors being kept constant. The results indicate an increase in stress with skew, which is of particular importance during backing.
Hydroelastic effects become potentially dangerous during backing of extreme skew-back propellers. When gradually increasing speed during backing a critical speed is approached at which the hydrodynamic forces and moments increase faster with angle of attack than the restoring elastic forces and moments do. This is a point of instability. Also well below the critical speed the hydrodynamic effects cause an increase in stress levels that cannot be neglected. One approximative and one more rigorous method to determine these effects are presented.

Published: November 2022

Objective
To identify coronary heart disease risk factors in young and middle-aged persons and develop a tailored risk prediction model.

Methods
A retrospective cohort study was used in this research. From January 2017 to January 2020, 553 patients in the Department of Cardiology at a tertiary hospital in Anhui Province were chosen as research subjects. The research subjects were separated into two groups based on the results of coronary angiography performed during hospitalization (n = 201) and non-coronary heart disease (n = 352). R software (R 3.6.1) was used to analyze the clinical data of the two groups. A logistic regression prediction model and three machine learning models, including BP neural network, Extreme gradient boosting (XGBoost), and random forest, were built, and the best prediction model was chosen based on the relevant parameters of the different machine learning models.

Results
Univariate analysis identified a total of 24 indexes with statistically significant differences between coronary heart disease and non-coronary heart disease groups, which were incorporated in the logistic regression model and three machine learning models. The AUCs of the test set in the logistic regression prediction model, BP neural network model, random forest model, and XGBoost model were 0.829, 0.795, 0.928, and 0.940, respectively, and the F1 scores were 0.634, 0.606, 0.846, and 0.887, indicating that the XGBoost model’s prediction value was the best.

Conclusion
The XGBoost model, which is based on coronary heart disease risk factors in young and middle-aged people, has a high risk prediction efficiency for coronary heart disease in young and middle-aged people and can help clinical medical staff screen young and middle-aged people at high risk of coronary heart disease in clinical practice.

The sustainable improvement of maize productivity and smallholders’ incomes to contribute to food security is the objective of this study carried out over two consecutive years (2020 and 2021) at the University of Lomé Agronomic Experiment Station. The experiment was set up in a split-plot design, composed of sixteen (16) treatments in three (03) replicates each. Four varieties: Ikenné (V1) Tzee (V2), Sotubaka (V3) and Sammaz 52 (V4) and four fertilization schemes: 0 kgha-1 (F0); 200 kgha-1 of NPK: 15-15-15+100 kgha-1 of urea 46%N (F1); 6 000 kgha-1 of chicken dungs (F2) and 6 000 kgha-1 of small ruminant dungs (F3) were the studied factors. Maize grain yields were determined, and an economic analysis was done. The results analysis showed that varieties and fertilization schemes significantly affected maize grain yields. Sotubaka (V3) was the most productive variety during the two years of experiment. The average yield obtained under V3 (3.56±0.65 t ha-1) was higher than those of Ikenné, Tzee and Sammaz 52 varieties respectively by 20, 57 and 5%. The average yield recorded under F2 was higher than those of F0, F1 and F3 by 54, 3 and 17% respectively. On a 2-year average basis, the application of 200 kgha-1 of NPK: 15-15-15+100 kgha-1 of urea 46%N (F1) gave the highest maize grain yields under V1 (3.43±0.13 t ha-1) and V2 (2.60±0.15 t ha-1); while the highest maize grain yields under V3 (4.29±0.12 t ha-1) and V4 (3.95±0.11 t ha-1) were obtained with the supply of 6 000 kgha-1 of chicken dungs (F2). On the same 2-year average basis, the highest profits were obtained under Ikenné (343 000 FCFA ha-1=US$ 512.46) and Tzee (177 000 FCFA ha-1=US$ 264.45) with the application of F1. For Sotubaka (480 000 FCFA ha-1=US$ 717.14) and Sammaz 52 (415 000 FCFA ha-1=US$ 620.03), the highest profit was obtained with the application of F2. For successful maize cultivation, it was advisable to use F1 for Ikenne and Tzee varieties and F2 for Sotubaka and Sammaz 52 varieties.

Published: November 2022

Purpose: The purpose of this study was to examine the extent to which formal announcement of inflation targeting impacts on inflation and inflation volatility, from an emerging economy’s perspective.
Methodology: Annual time series data from 1985 to 2014, which was sourced from the World Development Indicators (WDI) and the Bank of Ghana (BoG) was used. The data was interpolated into quarterly data using E-Views. The GARCH (1 1) and AR 2-Newey West Models were employed.
Findings: The study found that the formal announcement of inflation targeting had a significant negative impact on inflation and its volatility. Thus, the study discovered that research works arguing that inflation targeting has no beneficial influence on inflation must take into account the type of economic structure at play, policy credibility, institutional efficiency, and the general public's responsiveness to institutional policies and information.
Implications: This scholarly work would aid policy makers, academic institutions and the understanding of the general public in matters of inflation targeting. This paper concludes that the formal announcement of inflation targeting contributes greatly to stabilize both the inflation rate and inflation volatility, and that, countries that adopt a piloting-based adoption will not achieve the gains of the policy framework within the piloting period.

Background: Lack of knowledge and awareness of the society is one of the major contributing factors to the prevalence of counterfeit medicines in a country. There is limited information in the developing countries on university student’s facts concerning counterfeit medicines.
Aim: To assess how the university student either in medial or non-medical colleges identify counterfeit and substandard medicines and to evaluate their vulnerability level toward counterfeit drugs.
Methods: Structure electronic questionnaire was distributed in Saudi Arabia, between December 2020 till March 2022. The sample included 1216 respondents selected conveniently from two distinct groups (Student in either medical or non-medical colleges). 1204 participants who were fluent in either English or Arabic were included. The objective of this study is to give better understanding of counterfeiting in drugs and how to fight it.
Results: From one thousand two hundred and sixteen questionnaires were distributed to university student both medical college and non-medical college, only 12 were refused to participate, which indicate higher in response rate. 85% of the answers were female, 36% below 20 and 92% of them were Saudi citizen wit 67% single state. Most of the results of the survey (38 items) were insignificant (p-value>0.05) only 13 (34%) question of the survey relived significant. So, more awareness towards counterfeit medicines, in the level of university student will needed reduce the lack of knowledge.
Conclusion: Although medical school students have higher knowledge about counterfeit drugs, nevertheless, the overall findings suggested low-level of knowledge, exposure to counterfeit were estimate in both medical and non-medical college students in most of the surveyed items.

AbstractPurposeDescribe an early‐adopting institution's experience with online adaptive radiation for stereotactic partial breast irradiation.Methods and materialsRetrospective review of 22 women treated between May 2021 and March 2022 with adaptive stereotactic partial breast irradiation. A total of 106 of 110 fractions were evaluated for dosimetric changes in target coverage and organ‐at‐risk (OAR) dose. Patient set up with stereotactic wooden frame and adapted per fraction. Treatment and planning times were collected prospectively by radiation therapists.ResultsScheduled PTV30 Gy was <95% in 72.1% and <90% in 38.5% of fractions, and both PTV and CTV coverage were improved significantly after adaption, and 83.7% of fractions were delivered as adapted per physician choice. There was no difference in OAR coverage. Average adaptive treatment planning took 15 min and average time‐on‐couch was 34.4 min.ConclusionsAdaptive stereotactic breast irradiation resulted in improved target coverage with equivalent dosing to OARs in an efficient and tolerated treatment time. Improved target coverage allowed for decreased PTV margins compared to prior trial protocols that may improve acute and late toxicities.

Published: November 2022

AbstractThe treatment of diabetic wounds remains a great challenge for the medical community. Here, a smart patterned DNA double helix (duplex)‐like fabric based on genetically modified spider silk protein (PDF‐S) which is inspired by soft plant tendrils, is proposed for diabetic wound treatment. Benefiting from spider silk protein (spidroin); PDF‐S is equipped with high strength; high toughness, and excellent biocompatibility. Notably, the fabric crimped through the biomimetic DNA double‐helix‐like structure can effectively adapt to tensile impact and the maximum stretch rate reaches 1500%. A pattern‐based microfluidic channel of PDF‐S allowed wound secretion to flow spontaneously through the channel. Meanwhile; due to the optical properties of the introduced photonic crystal structure; PDF‐S is equipped with fluorescence enhancement properties; enabling PDF‐S to display color‐sensitive behavior suitable for wound monitoring and guiding clinical treatment. In addition, to enable sensitive motion monitoring, microelectronic circuits are integrated on the surface of the PDF‐S. These unique material features suggest that this study will lead to a new generation of biomimetic artificial spider silk materials for design and application in the biomedical field.
