Influence of Cooling Methods in Friction Stir Welding of 7075 Aluminum Alloy
Authors: Saeyang Paisan
Published: May 2023

Regarding various part manufacturing in industrial scale, one of the most popular processes was welding, especially in automotive and aircraft industries. It was well known that these industries have an increasing rate of aluminum consumption every year. There was due to aluminum has many outstanding properties such as light weight, high strength to weight ratio and very good elongation. One of the most used aluminum alloys was AL7075, which is suitable for highly stressed structural applications in aircraft structural parts. However, fusion welding techniques were usually yielded poor strength for such grade of aluminum. Friction stir welding is a solid-state welding technique that joins two workpieces without melting the workpiece material. Heat was generated by friction between the shoulder of the stirring tool and the workpiece. The probe was to stir and mix two metals parts together. However, the Thermo Mechanical Affect Zone (TMAZ) and Heat Affect Zone (HAZ) were reported as the weakest area of welded parts. Therefore, this study aims to improve the joints by cooling processes during welding using cutting fluid and cryogenic cooling with different parameters such as welding speed and shoulder size. The results of these experiment indicated that the cooling process influenced the mechanical properties of the joints. The micro-vicker hardness showed a significant increase in TMAZ and HAZ area.

Published: May 2023

The present research attempt to propose a testing methodology, some preliminarily test results and data interpretation method to estimate effects of soil lumps on properties of compacted soil. Lumps of soil with various dimensions, from smaller than 1.18 mm to 37.5mm, are prepared and each dimension of soil lump is compacted with OMC to a cylindrical soil sample which is then compared with the sample obtained from conventional standard compaction test in which all soil lumps are thoroughly broken up before mixing with OMC (ASTM D698 – 12). Therefore effects of the soil lumps with several dimensions on moisture content distribution, dry density and strength of the compacted soil can be investigated. Eventually, data interpretation to estimate effects of lumps on properties of compacted soil is introduced for further application of soil compaction quality control
Methods for Assessment of Early Age Shrinkage Cracks in Higher Strength Concrete: A Review
Authors: Kulkarni Y. U. , Awati M. M. , Khadiranaikar R. B
Published: May 2023

High-strength concrete is a type of concrete with compressive strength greater than 40 MPa (megapascals), which is much higher than the strength of normal concrete. High-strength concrete is often used in construction projects where greater strength is required, such as high-rise buildings, bridges, and other structures that need to withstand heavy loads or harsh environments. The high strength is achieved through the use of high-quality materials and careful proportioning and mixing of the concrete. Higher strength concrete experiences excessive early age cracking due to low water binder ratio. This early age shrinkage cracking directly affects the strength and durability of concrete. This paper discusses a review of methodologies used to assess the early age shrinkage cracks in concrete which will help in further high strength concrete shrinkage cracking study. In this review restrained shrinkage ring test, free shrinkage tests are discussed

Authors: Yulianti Serliana , Riqwan Iqbal Hibni , Wibisono Jefri Tanjung , Park Sunho
Published: May 2023

Studies have shown that step modifications support the planing hull's ability to accelerate quickly; nevertheless, it also produces excessive drag and creates the hump area extremely trim. Engaging integrated with the interceptor will improve the efficiency of the step hull. Planing hull interceptors are placed at the transom stern to regulate the trim angle and reduce movements caused by seas. This study is focused on the effects of step hulls with interceptors on pressure distribution and how they affect the planing hull's drag, heave, and trim. The environment was modeled according to the two-degree of freedom condition to simulate trim and heave. A combination of an overset mesh and the Finite Volume Method (FVM), the Reynolds-Averaged Navier-Stokes equation, was used to evaluate this study. The water and air phases are represented by the turbulent K- and VOF (Volume of Fluid) models. The errors driven by grid spacing and time-step have been estimated using grid convergence studies. The numerical approach was tested experimentally by Park et al. to ensure accuracy. It has been determined through calculations of the drag, trim, and heave results that adding an interceptor to a step vessel is extremely valuable for minimizing drag and controlling trim

Artificial Intelligence and Creative Thinking, the Future of Idea Generation
Authors: Teimuraz Goderdzishvili Teimuraz Goderdzishvili
Published: May 2023

Artificial intelligence has been the most successful modern technology created in recent years. Its development began in the 1960s and was based on simulating the human brain. The scientific community's interest has focused on developing machine-learning neural networks and their potential applications in music, art, architecture, and other fields. AI is increasingly capable of generating creative ideas and assisting humans in decision-making processes. With advanced algorithms, machine learning, and natural language processing, AI has the potential to revolutionize creative thinking. In this article, there is discussed whether AI can generate creative ideas and how expressive and creative these ideas can be. AI technologies can be used in creative industries such as content creation, information analysis, information retrieval, and processing.
The purpose of new technologies is to automate specific processes, simplify them, maintain accuracy, and reduce production costs. In some cases, they enable us to complete tasks or solve problems that were previously impossible. AI is a set of codes, methods, algorithms, and other data that allow a computer system to imitate human behavior and make human-like decisions. AI systems widely use data compression and storage capabilities, which enable them to process information by observing human actions and behaviors.
To generate creative ideas, AI requires a different level of training and expertise, a faster rate of information processing, and high-quality analysis. Advances in AI largely depend on data relevance. Human creative thinking often uses imagination to generate original ideas that may not follow general rules. Creative tasks usually require originality of thought and innovation, which can be challenging to replicate with AI systems.
Artificial intelligence has shown mixed results in both original creative and automated work processes. However, it is increasingly being associated with human creativity and original thinking. Over the decades, numerous studies have been conducted on the use of artificial intelligence in the creative field.
Keywords: Creative idea, digital technologies, artificial intelligence, machine learning language (NLP).
National Wealth as an Economic Category
Authors: Nato Chikviladze Nato Chikviladze
Published: May 2023

National wealth is one of the most general economic categories and an integral indicator for assessing and comparing the economic potential and capabilities of different countries. The calculation of such important macroeconomic quantities is based on the system of national accounts. In the economic literature, the term wealth refers to the sum of certain elements. In the economic literature, the term "wealth" refers to the sum of certain elements. In this sense, "wealth" is the object of economic science and statistical research. Country, nation, people, social wealth - these categories emerged with the formation of economic science. The first mention of the category "national wealth" in foreign literature is associated with the works of the classical economist W. Petty. In his search for the source of wealth, the author quantified the economic events of his time. In 1664 the scholar calculated the national wealth of England.
Two concepts have emerged: national wealth is regarded as a certain fund held by a country in a certain period of time, or as recurrent income, a certain flow of products processed and used by the state, of the country over a certain period of time. The second concept dominated 19th century science. In our view, the definition of national wealth as a certain flow over a certain period of time is more characteristic of the concept of national income or gross product. For a scientifically sound and legitimate characterization of the concept of national wealth it is necessary to combine these two approaches. Only from the middle of the 20th century onwards. National wealth is identified with the accumulated stock of tangible and intangible assets. All elements of national wealth have a material composition, i.e. represent the material wealth of society. But on the wave of scientific and technological progress, information played a big role, in the mid-twentieth century the economy transformed from industrial to neo-industrial, and intangible elements were included in national wealth: human capital and information. If we compare countries by the level of national wealth, it is known that natural resources prevail in the structure of national wealth of low-income countries, and human potential prevails in high-income ones. In order to achieve a certain level of socio-economic well-being, most researchers believe that forms of international division of labor and organization are necessary to enable less developed countries to change the proportions of national wealth. and increase the proportion of human potential.

Transfusion de produits sanguins labiles en réanimation pédiatrique
Authors: Demaret Pierre
Published: May 2023

Les transfusions de produits sanguins labiles sont indispensables pour la prise en charge adéquate de diverses pathologies. Toutefois, elles ne sont pas sans risques, si bien que leur usage doit être raisonné.
Pour les globules rouges, une stratégie transfusionnelle restrictive, privilégiant des seuils transfusionnels plus bas (hémoglobine 70 g/L) que ce qui était historiquement recommandé (hémoglobine 90-100 g/L), peut être recommandée pour la plupart des enfants admis en réanimation : elle permet de réduire la consommation de concentrés érythrocytaires sans affecter le pronostic des patients. Bien qu’une stratégie plus libérale puisse être envisagée sur base du jugement clinique dans certaines circonstances (incluant l’hypoxémie sévère, l’instabilité hémodynamique, le traumatisme crânien grave ou encore la dysfonction myocardique sévère), aucune donnée solide n’appuie l’intérêt d’une transfusion si l’hémoglobine est supérieure à 100g/L.
Les données de la littérature sont beaucoup plus pauvres pour les transfusions de plasma et de plaquettes en réanimation pédiatrique, si bien que les experts ne peuvent recommander formellement une transfusion qu’en cas d’hémorragie massive, alors qu’ils invitent à utiliser le jugement clinique dans la plupart des autres situations.
La recherche en médecine transfusionnelle doit être poursuivie afin d'obtenir des données permettant de développer des recommandations transfusionnelles davantage basées sur l'évidence.
Management of patients with acute heart failure/cardiogenic shock complicating a valvular disease
Authors: Aguilhon Sylvain , Roubille François , Delmas Clément
Published: May 2023

Cardiogenic shock (CC) is the most advanced and severe stage of heart failure.

Its management requires a rapid diagnosis, an etiological evaluation and the initiation of an adapted treatment as soon as possible.

Even if ischemic etiology remains preponderant, the prevalence of other causes, notably valvular, is constantly increasing.

In our industrialized countries, aortic stenosis is the most frequent valve disease, followed by mitral insufficiency, aortic insufficiency and mitral stenosis.

While the management of these valvulopathies is well codified and has been evolving over the last few years, acute management is less clear.

Inotropic treatments and mechanical circulatory support are part of the therapeutic arsenal available, but the correction of the valve disease remains the main problem.

Conventional surgery is unfortunately difficult to consider because of its high moribidity and mortality. Percutaneous techniques are therefore an alternative, even if few data are available and their development according to the type of valve disease is uneven.

This update provides an overview of the different valve diseases in the context of CC and summarizes the different therapeutic options available in such a critical situation.
Programming and financing of development Forces - the old and new approach on the basis of Poland's experience
Authors: Chyrzyński Ryszard
Published: May 2023

Objectives

Analysis of the increased financial effort of the state related to the intensification of the process of developing the country's defense potential, including in particular the process of programming and financing the development of the Polish Armed Forces.

Methods

Theoretical and empirical scientific methods have been used in the development of this publication. The theoretical methods are analysis and synthesis of source documents and comparative analysis. The empirical method was participant observation of the processes of planning, programming, and budgeting the development of the Polish Armed Forces.

Results

A comparative analysis of various source materials, shaping expenditures on securing the state's defense needs, allowed the author to prove the thesis that an appropriate level of these expenditures can actually improve the overall security of the country, as well as the capabilities of its Armed Forces.

Conclusions

The geopolitical situation that has arisen in recent months around the borders of Poland forces the state to significantly accelerate the process of intensifying the development of the country's defence potential, including technical modernization and development of the Armed Forces. The implementation of the tasks for the security and defence of the state has required many changes for years in relation to:
- the obligation to defend – issues related to qualification, the course of the recruitment process for military service, or the defence duty of citizens;;
- military service – issues related to broadly understood military service;
- programming and financing of the Armed Forces – issues related to obtaining new sources of financing;
- implementation of tasks by entrepreneurs for the armed forces – issues related to the change in the design, financing and competence of government administration bodies.

Early Resident Support for a Mega-Event: Evidence from the 2032 Brisbane Summer Olympic Games
Authors: Weaver David B. , McLennan Char-Lee , Moyle Brenta , Casali Luca
Published: May 2023

With fewer willing hosts, mega-events face uncertainty. From stakeholder and core/periphery perspectives, dystopic outcomes are occurring because mega-event elites benefit far more than peripheral stakeholders, including host city residents. To overcome the current crisis of confidence
in mega-events and enable procommunity ideals of stakeholder theory, we identify levels of host community support for the 2032 Brisbane Olympic Games in the early preevent stage, when proactive planning interventions are still possible. Two thirds of 897 surveyed host city respondents supported
the Brisbane Games in our 2022 study, but this support is "soft." Specifically, cluster analysis reveals an event-loyal inner periphery of "enthused legacy optimists" and "enthused immersives" who can be targeted for early personal engagement and recruitment of other residents, especially
the large middle periphery of "skeptics." A passively opposed outer periphery of "neutral negatives" and "naysayers" was also identified that may resist recruitment but is unlikely to disrupt preparation or hosting.

ROLE OF ULTRASONOGRAPHY IN DIAGNOSIS OF SPINAL STENOSIS WITH LUMBAR OSTEOCHONDROSIS
Authors: Abdullaiev R. Ya.
Published: May 2023

Diagnostic visual examinations for patients with any type of spinal stenosis include either magnetic resonance imaging or computed tomography with myelogram, sometimes both tests are prescribed to patients. Ultrasound is usually most effective for tissues with a high content of collagen, i.e. tendons, ligaments, joint capsules and fascia. In osteochondrosis, spinal ultrasonography is used to determine whether a back pain is the result of cracks or a herniated disc. To evaluate the possibilities of ultrasound in diagnosis of lumbar spine stenosis, an analysis of its results in 48 patients aged 41−57 years. Forty five of them were diagnosed with intervertebral disc herniation, 3 with protrusion of various localization and hypertrophy of the yellow ligament. All the patients underwent radiography, magnetic resonance or computed tomography, as well as ultrasound. In 24 patients the laminectomy was performed in 31 discs. In 21 cases, the hernia was paramedian, in 17 it was − median and in 14 this was circular. Laminectomies were performed much more frequently due to median and circular hernias. The slightest deformation of spinal canal is observed in the posterolateral localization of hernia or protrusion. In thin individuals, ultrasound images of the spinal canal elements were excellent, in those with moderate weight they were slightly inferior to magnetic resonance imaging. In three cases of spinal canal stenosis in obese patients who underwent laminectomy, the results of ultrasonography were unsatisfactory and the decision for surgery was made only on the basis of magnetic resonance imaging. It is concluded that ultrasound is a very informative way of assessing the degree of lumbar spine stenosis resulted from degenerative changes in intervertebral discs.

Key words: ultrasonography, spinal canal stenosis, lumbar osteochondrosis, lumbar intervertebral discs.

Utilization of HP is not only from certain circles or ages, but almost all groups and ages, both adults and children, use HP for business and entertainment. Webinars and online are one of the important strategies to fill school activities that were stopped during the pandemic. Over time and during the pandemic, the use of HP increased sharply. It is common nowadays that we see every opportunity and in various places people spend their time with HP. This of course will result in HP being damaged or error quickly. Seeing this condition, it is important for SMK students to have the expertise to repair cellphones that are damaged or have errors. Repairing a cellphone must first understand the theory of the device both hardware and software. Hardware-wise, the first step is how to open the HP case itself and use a precise toolkit, recognize the electronic components contained inside, map out potential damage that occurs and finally replace damaged components or modules. In software, what is done is to find the cause of the operating system or application program that is corrupt or degraded. Is it necessary to take action to upgrade or update the application software? For that students need basic training on how to repair HP. Sometimes everyone who has a damaged cellphone immediately takes it to a technician, and the price is very expensive even though the level of damage is very simple. If you understand the symptoms of damage and understand the basics of electronics, the HP damage can be repaired.

Solid solutions of phosphate-vanadates Ca9La(PO4)7(1–x)(VO4)7x:Eu3+(1 %) with the structure -Ca3(PO4)2 activated by europium were synthesized by the standard solid-phase method. It is shown that a continuous series of solid solutions is formed upon substitution P5+ → V5+. At the same time, the study by the second harmonic generation method showed that a symmetry inhomogeneity is observed in the series. When studying the luminescent properties, standard transitions of the europium cation with the dominant electric dipole transition 5D0 → 7F2 were found. The most intense emission was demonstrated by compositions with a centrosymmetric structure.

A number of new metal-containing monomers have been obtained by direct interaction of unsaturated mono- and dicarboxylic acids with silver nitrate. The study of their thermal properties showed that thermolysis proceeds in two or three (for crystalline hydrates) stages. The end products of thermolysis are silver nanocomposites containing metallic silver nanoparticles stabilized by a carbon matrix. Silver particles are located relatively evenly in the object, the amplitude during scanning in a given direction allows us to state that the particles have a shape close to spherical, while some of the large particles, about 30 nm, are aggregates of smaller particles formed during thermolysis.

The deformation behavior of model highly filled metal polymer aluminum powder compositions in polyethylene glycol under simultaneous action of compression and shear studied. The compression module increases with the increase of the compression, wherein the shear module significantly reduces. The discovered effect is related to the redistribution of the elastic layer between the rigid particles of the filler in the normal direction and in the shear area. The model of behavior of highly filled polymer compositions in these conditions proposed.
