The article investigates the potential applications of free open-source software in image processing for a diverse range of industrial uses, including laser texturing, machining, and additive manufacturing. A case study is presented, wherein digital photography is utilized to capture a scene, followed by processing in the GNU Image Manipulation Program. The processed image in the form of a height map is then imported into the Blender software suite to generate a high-resolution 3D model. The quality of this model is further enhanced using various software functions such as object modifiers, and mesh sculpting. Based on the high-quality 3D model, a high-resolution height map is rendered. Subsequently, the exported height map is utilized for surface modification through laser beam technology and additive manufacturing via fused deposition modeling. This analysis aims to investigate the efficacy and adaptability of open-source software in industrial settings. The article also highlights the steps involved in: 1) capturing an image digitally through photography, 2) creating a 3D artistic relief in Blender, 3) converting the polygonal model of the relief for laser micromachining graphics, and 4) adapting the polygonal model for 3D printing graphics. The study concludes with an evaluation of the results, examining the suitability of use of open-source software for generating relief from photographs for various industrial applications

This study explores the use of natural substances as resources in the development of UV protective coatings, offering an environmentally sustainable alternative to toxic and synthetic materials, mostly organic compounds used as UV stabilizers in various industrial and commercial applications. Therefore, the focus of this study is on different natural sources possessing protective properties. To ensure adequate protection, it is necessary to carefully consider and properly blend various substances that possess protective properties against UV radiation and free radical formation. UV radiation poses a constant threat to materials, promoting oxidative stress that can cause serious damage. In this context, UV stabilizers play a crucial role in protecting materials from degradation caused by solar radiation. Their ability to absorb or reflect UV radiation is crucial for preserving the physical and chemical properties of polymeric materials, coatings, inks and coloration. On the other hand, antioxidants are additives that protect against oxidative stress by neutralizing free radicals - reactive compounds that are formed under the influence of UV radiation and can cause material damage. UV stabilizers, in synergy with antioxidants, often result in optimal material protection, ensuring durability and preservation of the aesthetic and functional properties of products. Therefore, a formulation that includes carefully selected UV stabilizers and antioxidants, is crucial for achieving a high level of protection against the harmful effects of UV radiation and free radicals. This integrated approach not only ensures material durability but also contributes to sustainability. This study emphasizes the need for further research aimed at developing new technologies that could enhance the interaction between UV stabilizers and antioxidants to achieve optimal material protection.

Effective ergonomic packaging ensures efficient and intuitive product handling, providing easy access and a secure grip, thereby enhancing user experience. Achieving this involves optimizing packaging size, shape, and material. This study investigates the application of screen printing with puff-enhanced ink to improve packaging ergonomics. Puff-enhanced ink augments surface roughness, thereby enhancing tactile perception and grip security. This research utilized objective measurements and subjective evaluations to assess the impact of tactile properties on manual pulling force. Building on prior work where the mesh count of 120 l/cm was investigated, this study explores prints created using a screen with a mesh count of 63 l/cm. Three substrates were used: bulky paper, paperboard, and matte-coated kunstdruk paper, with the amount of added puff base varied between 0%, 10%, 20%, and 30%. The findings reveal that surfaces with increased roughness not only enhance grip and increase the manual pulling force but also suggest how different substrates and mesh counts impact the ergonomic properties of packaging. This contributes to a better understanding of the optimal conditions for effectively applying the puff base in the packaging industry.

Nowadays, manufacturers across various sectors, including food, cosmetics, pharmaceuticals, and other industries, are continually expanding the range of products available in the market. Given this expansion of products, branding, and packaging have become critical differentiating factors. To effectively influence consumer behaviour and encourage brand preference, packaging designers must thoroughly understand the challenges faced by existing products and the needs of consumers. By employing various graphic elements, such as colour palettes, illustrations, typography, and others, designers can effectively present products and communicate with consumers, thereby enhancing product recall. To achieve these objectives, it is essential to investigate whether specific patterns exist in consumer perception regarding packaging. This is precisely why this preliminary research was conducted. A total of 40 participants, divided into two groups, aged 20 to 25, from the same demographic group (students) participated in this eye-tracking analysis. Each group of participants had a different set of stimuli, depending on whether the subject of the test was logo font-weight variation or illustration size variation. The results of this preliminary research show that logo font weight has no statistically significant effect. Also, the results of this research show that the specific graphic element - illustration is observed the longest, regardless of the size change.

Fillers are used extensively in all types of polymers such as thermoplastics, elastomers and thermosets. It is considered impossible to develop many polymers without fillers. The primary purpose of using fillers in polymer materials is to reduce cost, but as polymers have become cheaper and more commoditized today, the main purpose of using fillers is no longer to reduce cost. A wide variety of fillers are available, and with their careful selection, composite materials with improved properties for functional use can be produced. The main reasons for using particulate fillers today vary by polymer type but include improved processing, increased hardness, thermal distortion temperature and creep resistance, better wear and tear resistance, and flame retardancy. In this study, it was aimed to use organic-based hornbeam wood sawdust together with inorganic-based calcite filler. Thus, it is aimed to obtain an environmentally friendly green material. General purpose polyester resin was chosen as the matrix material for the composite due to its extensive use in industry. Hornbeam wood sawdust and calcite were used as fillers, mixed with polyester resin in certain proportions. Composite samples were obtained by open mould casting method. The filler rate was determined as 20% limit value, taking into account literature studies. Izod impact tests, tensile tests, and hardness tests of the composite samples were performed and SEM images of the broken surfaces were examined. Since the composite samples contained organic fillers, water absorption tests were also performed. As a result of the study, it was evaluated that the use of hornbeam wood sawdust and calcite together increased the impact and tensile strength, and therefore hornbeam wood sawdust could be used as a filler together with calcite in sectors such as paint and plastic.

Background: Parkinson's disease (PD) is a degenerative condition that impacts the nervous system and the body's functions regulated by the nerves. The symptoms begin gradually. One possible initial sign is a slight tremor in one hand that is hardly noticeable. Tremors are frequent, yet the condition may also result in rigidity or decreased mobility.
Methods: This was a descriptive cross-sectional study in which 456 individuals from the general population of Makkah City were randomly selected to complete an online survey distributed through social media platforms.
Results: Most of the study participants were men (52%), with 60.3% in the 18-30 age range and 64% having a bachelor's degree. The participants demonstrated a strong grasp and knowledge of PD. Most of them were aware of it, with 63.6% knowing it. Nevertheless, 51.3% believed that PD could be cured. Tremors were identified as the most common symptom (71.5%), and 58.6% thought that exercising does not increase the risk of acquiring PD. Additionally, 46.3% perceived PD as being more widespread among males than females, whereas 45.8% believed it is equally prevalent in both genders.
Conclusion: The citizens living in the Makkah municipality have a solid understanding of PD and positive attitudes toward it. The development of health education initiatives in partnership with policymakers and other invested parties could enhance public knowledge and awareness of PD.

La indisciplina literaria
Authors: Pineda Buitrago Sebastián
Published: October 2024

La pregunta de investigación que rige nuestro libro plantea si la emergencia de los estudios culturales es una consecuencia de lo que llamaremos la «indisciplina literaria». Para entender de qué se trata la «indisciplina literaria» nuestro libro se remonta a la organización moderna del conocimiento establecida durante la Ilustración kantiana o prusiana, organización en la que tanto la literatura como la filosofía, en especial esta última, desataron un “conflicto de las facultades”. Aunque en el siglo XIX latinoamericano hay cierto cultivo de la lingüística y de la ecdótica, las técnicas hermenéuticas de la filología germana lucen por su ausencia, es decir, hay una indisciplina en la interpretación, un desdén por la educación poética y por la edición crítica, desdén que parece redimirse muy vagamente cuando las facultades de leyes expulsan de sí y hacen nacer de manera aparte, a principios del siglo XX, las facultades de letras.
La muerte y el garabato. Obras de creación original de música de cámara y para orquesta
Authors: González Cabrera Héctor Manuel
Published: October 2024

La muerte y el garabato La partitura de este díptico tiene un epígrafe que anuncia el motivo extramusical de la pieza; se trata de un texto tomado de la Apología de Sócrates: “Nadie conoce la muerte ni sabe si es el mayor de los bienes del Hombre. Sin embargo, se la teme como si se supiese con certeza que es el mayor de todos los males”. La obra pretende mostrar y contrastar dos visiones casi opuestas del hecho luctuoso de que en la cultura de Occidente representa una de las mayores fuentes de dolor para los seres humanos. Es por esto que la primera parte del trío pretende expresar tensiones dramáticas asociadas con el duelo en nuestra cultura. La segunda parte, de corte dancístico, evoca la mirada festiva que muchas sociedades no europeas –de ancestro africano en este caso– tienen sobre el acto de la muerte. El Garabato, de hecho, es el nombre de una de las danzas de chandé que se baila en los desfiles de la fiesta de carnaval anual de Barranquilla, que es protagonizada por un personaje que utiliza un disfraz que simula una osamenta humana. El patrón rítmico que acostumbra tocar la tambora, perteneciente al conjunto organológico tradicional conformado por otros membranófonos, idiófonos y algún aerófono, es recreado en la parte del piano.
Napoleon's Civil Code in the Political Discourse of the Alexander Era
Authors: Gotovtseva Anastasiya Gennad'evna
Published: October 2024

Napoleon's "Civil Code" is a fundamental work of European legal thought. M.M. Speransky, appointed by Emperor Alexander I to the Commission for Drafting Laws, of course, could not help but refer to this text; moreover, he actively used it when drafting his famous "Draft Civil Code", but revised many of its provisions when adapting it to the class-based Russian society. Nevertheless, the influence of the Code on Speransky's "Draft" was so noticeable that it caused sharp rejection in conservative circles. The main opponents of the Secretary of State were N.M. Karamzin and A.S. Shishkov, who criticized the "Draft". When writing this article, the main method was the method of discourse analysis. This method, the subject of which is traditionally defined as "speech immersed in life", made it possible to study the extralinguistic aspects of the texts of participants in the communicative field in political disputes around the legislative initiatives of M.M. Speransky in terms of their correlation with Napoleon's Civil Code. Also used were such methods as content analysis, biographical method, comparative-historical and contrastive. Despite all the similarities, the positions of Karamzin and Shishkov differed. If Shishkov categorically did not accept any changes to Russian statehood, defending the need to preserve its absolutist inviolability, then Karamzin, who admired Robespierre in his youth, then idolized Napoleon, openly declared his republicanism. The ambiguity of his position, which has been repeatedly noted by researchers, is fully explained by the phenomenon of the development of republican thought of that time, which is shown in the article. Speransky, responding to criticism of the "Project Code", stated that all such projects are similar, since they have Roman law as their source. But this was not important for his opponents, who used all available tools to discredit him.
Victim’s Right to Compensation from the Money Launderer: A Comparative Perspective
Authors:   Prosecutor of Southern Kurzeme Prosecution Office, Latvia, Eglaja Liene
Published: October 2024

Money laundering in Latvian law is considered a criminal offence against the interests of the financial system and the administration of justice. However, money laundering may also affect the property interests of the victim of a predicate offence whose assets due to money laundering have become unrecoverable. The study examines whether the victim can claim compensation from the launderer under Latvian law compared to Swiss and German laws. The results show that Latvian courts do not consider money laundering activities to cause economic losses to the victim, thus excluding compensation. However, payment of the value of the laundered assets may be ordered for the benefit of the victim. In contrast, Swiss and German courts acknowledge economic losses stemming from the money laundering itself, which provides a basis for compensation. Both approaches lead to different legal issues, which are analysed. Keywords: economic losses; money laundering; right to compensation.

Academic as well as scientific institutions are essential for advancing knowledge and innovation, but they are increasingly susceptible to foreign interference, which can compromise research integrity, academic freedom and national security. Increased remote work and study, large data volumes and disruptive technologies like Artifitial intelligence I have created new avenues for cyber threats. This article aims to explore the cyber risks associated with foreign influence on academic institutions specifically and suggest effective mitigation strategies. Foreign interference can lead to unauthorized access to sensitive research data, resulting in espionage, manipulation and lost commercialization opportunities. Dependence on foreign digital systems heightens these risks, including the potential loss of access to research data stored in third-party clouds. Furthermore, cyber interference can disrupt academic work, impacting online learning platforms and administrative systems. Common cyber threats, such as cyber-technology attacks and insider threats, underscore the need for strong cybersecurity measures. Keywords: academic institutions; cybersecurity; foreign interference.
A Novel Hydrogen Production System Based On Multistage Reverse Electrodialysis
Authors: Zhao Jiayue
Published: October 2024

Salinity gradient energy can be converted into hydrogen energy through the system combining multi-stage reverse electrodialysis (MSRED) with polymer electrolyte membrane water electrolysis. However, the relevant performance of the system has never been investigated. In this paper, the influence of relevant parameters of MSRED on the performance of the system was analyzed theoretically through a reliable mathematical model. The results showed that increasing the flow velocity of solutions will cause remarkable decrease in the energy recovery of the system, although the total output power and hydrogen production rate of the system increase correspondingly. Besides, thickening compartments of the high concentration solution is effective to reduce the energy consumption for pump with a small augment in the total output power and hydrogen production rate of the system, while the energy recovery of the system is still dropping slowly.
Donald Trump and the Collapse of Checks and Balances
Authors: Driesen David M.
Published: October 2024

This Essay analyzes Donald Trump’s erosion of checks and balances during his presidency and how President Trump will likely seek to complete their collapse if he regains power. Its First Part shows that congressional willingness to check presidential abuses of power declined during Trump’s presidency and will likely get much weaker in a second term. It also shows that President Trump figured out how to evade checks and balances from Congress in his first term and examines his plans to further usurp congressional powers. Part Two looks at the judicial role in facilitating or checking presidential power through a lens sharpened by an effort to understand how checks and balances might collapse. This Essay’s analysis enables us to see how events that most observers experience as a series of disconnected dramatic clashes over policy (or that largely escape notice altogether) have partially collapsed the constraints that constitutional democracy depends upon, and how this collapse will likely accelerate if Trump becomes President again.
Should test for dry eyes be done before age-related cataract surgery?
Authors: Balogun Modupe , Saka Idris
Published: October 2024

Objectives:

This study aimed to determine if tests for dry eyes should be done routinely before age-related cataract surgery.

Materials and Methods:

This was a hospital-based observational prospective study. Patients 50 years and above with age-related cataracts that met the inclusion criteria scheduled for manual small incision cataract surgery (MSICS) were assessed for dry eye disease (DED) before and after surgery. Numerical variables were described using the mean and standard deviation (SD) with a 95% confidence interval and P < 0.05.

Results:

A total of 81 patients were studied: 60.5% (49) males and 39.5% (32) females. The mean pre-operative Schirmer’s test value was 14.09 mm (SD = 10.7 mm). Post-operative schirmer’s test values were 18.12mm (SD = 11.81mm) at 1 week, 14.98mm (SD = 11.26mm) at 4 weeks and 16.20 mm (SD = 11.06 mm) at 6 weeks. Pre-operative mean tear break-up time (TBUT) was 10.05 (SD = 5.13 s), 9.46 s (SD = 4.18 s) at 1 week, 10.13 s (SD = 4.29 s) at 4 weeks and 9.80 s (SD = 4.33 s) at 6 weeks postoperatively. Lissamine green staining score (LGSS) Grade 0 was 80% at 1 week post-operative, Grade 0 increased to 85%, 90% at 4 weeks and 91% at post-operative 6 weeks.

Conclusion:

This study showed that DED is not associated with MSICS, and it is not associated with objective worsening of previously diagnosed DED. Testing for DED preoperatively plays a significant role in the pre-operative evaluation of patients and symptomatic expectations, but its testing before MSICS might not always be necessary.
Sustainable Approaches used in Pesticides contaminated Agricultural Waste Water Remediation
Authors: Verma Nitin
Published: October 2024

With the growing population of our global community and thereby increasing the demand for food has led the farmers to use more and more pesticides. Pesticides are chemical compounds used to kill pests. It is commonly used to control various agricultural pests that destroy crops and ultimately affect our agricultural productivity. Although the use of pesticides is a beneficial approach, but unfortunately it also has some drawbacks in terms of harming the environment and human health. Some pesticides pose significant hazards that ultimately affect human health systems. Contamination of agricultural land and agricultural wastewater by pesticides is a serious environmental problem and has a negative impact on biodiversity. Most synthetic pesticides are not readily biodegradable, they accumulate in the environment and cause soil contamination. To overcome the environmental burden of pesticide-contaminated sites, various sustainable approaches can be effectively used to detoxify contaminants or transform them into harmless secondary compounds. The current review focuses on the role of microorganisms and lignocellulosic biomass and plants in the degradation of agricultural pesticides under sustainable approaches.

Industrial dyes are major pollutants in wastewater and river water with an initial visible concentration of 1 mg/L. Recent studies have shown the possibility of using polyphenol oxidase in catalytic biological treatment due to its ability to oxidize a large number of dyes and pollutants in wastewater and the flexibility to work in wide ranges of temperature, pH and salinity. It is easy availability as well as the low economic cost resulting from its use in biological treatments, this enzyme polyphenol oxidase was used. The findings in this study showed that the extraction of polyphenol oxidase (PPO) from potato peel was homogenized with potassium phosphate buffer (0.1 M, pH 7) at a ratio of 1:10 (weight: volume) for two min. The result of enzyme purification by ion exchange chromatography showed that the yield of this step was 64 % and the specific activity was 6541.67 U/mg. The polyphenol oxidase was immobilized covalently on the functionalized pumice stone (25.2 U/gm) compared with other methods. The characterization results demonstrated that the optimum pH for immobilized and free enzyme activity was 6.0 while the pH range of free and immobilized polyphenol oxidase stability was from 4.5 -7.0 and 3.5 - 8.5 respectively. The better temperature for free and immobilized polyphenol oxidase activity was 25 ºC, whereas the free and immobilized polyphenol oxidase was stable at 15-35 and 15-50 °C respectively. The outcomes showed that the decolorization efficiency of blue textile dye employing immobilized polyphenol oxidase reached 99.85 % after 24 hr. for 100 mg/L concentration while for other concentrations 200, 300, 400, 500 and 1000 mg/L the decolorization efficiencies were 85.96, 76.15, 72.54, 66.94 and 63.5 % respectively. Based on the results, the immobilized polyphenol oxidase on pumice stone is highly efficient in removing textile dyes at large concentrations and in different environmental conditions.

PSYCHOLOGICAL AGE OF CIVILIZATION
Authors: Рыжов Б.Н.
Published: October 2024

The article presents the first part of the study devoted to the system periodization of the development of modern European civilization and to the comparison of the initial period of the development of civilization with the corresponding periods of human development. One of the main criteria considers the similarity of goals and means of expression of art of a certain period in the development of civilization and characteristics of human development in the particular period of life, including the features of game activities. From the point of view of systems analysis, art is a specific element of civilization representing an information model of major, substantial system links emerging within civilization at different stages of its development. The existence of such a model allows civilization to effectively reproduce and mold links, required for its development, in various zones of civilizational space. This determines the necessity of art for any civilization. Art is a conceptual design of a building or a ship which helps to construct not just one real building or one real ship, but any number of buildings or ships. Art plays the same role in the case of civilization as a game in the case of each individual. A childs or an adults play allows a human to form the relations which are essential for further life (or else to free oneself from unwanted, parasitic ties) these relations are formed through the imitation of real life situations, not putting a person at risk or endanging anyone. In the same way art, being the game of civilization, allows doing the same for social strata in their entirety and society as a whole. The functional semblance of the phenomena of modeling of real world system links in human games and in art allows us to assume that the aims and the expressive means which characterize the art of a certain period of civilization development can be analogous to the specificities of human development in the respective period of life. And moreover, these aims and means can be analogous to the aims and specific features of games played by man at a certain age. Thus, an opportunity is provided to compare the agebased periodization of human life and psychological age of separate epochs in the development of civilization, as depicted in works of art. In the presented part of the research we adduce the description of such analogies covering the initial period of European civilization development from approximately V to VIII centuries, which according to the proposed study corresponds to the first three years of a childs life.

Acid-Cleavable Poly(Oxazoline) Surfactants
Authors: Garcia Joseph , Vergara Mendez Ashley , Sletten Ellen
Published: October 2024

The low pH of the cancer tumor microenvironment and the late endosome is a tantilizing target for stimuli-responsive nanotherapeutics due to the accessibilility of these particular chemical differences to nanomaterials. Acid-cleavable surfactants are well-established for the formulation of stimuli-responsive nanoparticles and much work has been done to tune the sensitivity of these motifs to match their intended application. Acid-labile hydrazone-linked surfactants, specifically display increased stability over the more common imine linkage to prevent premature release outside of the cell, but remain labile enough for effective payload release once endocytosed. Furthermore, their cationic byproducts are known to facilitate enhanced endosomal escape through membrane disruption. Herein, we report the synthesis of a hydrazone-linked poly(oxazoline)-based diblock copolymer surfactant. This surfactant cleaves in a pH-dependent manner both in solution, and at the perfluorocarbon-water interface. We then demonstrate the ability of nanoemulsion encapsulated payloads to partition into cell membrane mimics only after cleavage of the surfactant. In all, this work demonstrates a viable route to create POx-based nanomaterials with controlled release capabilities in biologically relevant conditions and is a promising platform for advancing the endosomal escape and cancer targeting of nanomaterials.
Evaluación de la accesibilidad espacial a terminales portuarias de exportación de zonas de producción de café especial del departamento de Nariño: impacto del bloqueo vía panamericana
Authors: Goyes Chaves Daniel Mauricio
Published: October 2024

El café especial del Departamento de Nariño ha sido reconocido por su excelencia y calidad, tanto en el ámbito nacional como internacional. Sus granos se distinguen por sus atributos diferenciales, fruto de las condiciones climáticas y geográficas privilegiadas de la región, así como del esmero y dedicación de los caficultores Nariñenses. Sin embargo, este producto de excelencia enfrenta desafíos en su comercialización, principalmente debido a la falta de una red de infraestructura de transporte adecuada y equipamientos logísticos estratégicos. La infraestructura de transporte es el elemento vertebrador del territorio y el impulsor del desarrollo regional y bienestar económico, la cual se encuentra relacionada directamente con la accesibilidad espacial. La accesibilidad espacial ha sido definida como la facilidad que tienen las personas para realizar una actividad, en un uso del suelo, por un modo de transporte y en un momento deseado, fundamental en la planificación del transporte, esencial para la competitividad regional y cadenas productivas. En enero de 2023, un deslizamiento de tierra en el municipio de Rosas, Departamento del Cauca, generó un bloqueo en la vía Panamericana. Esta situación dejó al Departamento de Nariño incomunicado por tierra, dificultando el transporte de productos hacia el interior del país y a equipamientos de exportación. El objetivo del estudio es evaluar la accesibilidad espacial de las zonas cafeteras de la región a terminales portuarias de exportación. Se comparan dos escenarios, uno considera la red existente sin afectaciones y otro simula un bloqueo por deslizamiento de tierra en la vía panamericana, utilizando la ruta alternativa Pasto - San Francisco - Mocoa (Putumayo). El análisis contempla tresfases: caracterización de redes en condiciones normales y ruta alterna, modelación de la accesibilidad espacial mediante la generación de superficies continuas e Isócronas, la cuantificación del ahorro u aumento generado en las zonas productoras de los tiempos promedio de viaje. Los resultados revelan un aumento del 13,59 % en los tiempos promedio de viaje por la vía alterna, afectando la competitividad, calidad y seguridad de la carga. Estos hallazgos resaltan la necesidad urgente de enfrentar los desafíos en la conectividad y accesibilidad espacial de las zonas cafeteras de Nariño, fundamentales para el desarrollo sostenible y la viabilidad de las cadenas productivas regionales.
