Published: May 2024

As unidades de conservação brasileiras, inseridas no contexto do Sistema Nacional de Unidades de Conservação, compreendem uma política pública que busca efetivar a proteção da biodiversidade e dos recursos naturais. A despeito dessa importância, muito se tem discutido sobre a implantação de unidades de conservação e conflitos com comunidades locais. Nessa perspectiva, apresentamos uma reflexão sobre pressões socioambientais sofridas por algumas unidades de conservação de proteção integral no estado de Minas Gerais (Parque Nacional das Sempre-Vivas e pelos Parques Estaduais de Ibitipoca, Mata Seca e Serra do Papagaio), bem como sobre alguns conflitos gerados pela criação e implementação dessas unidades de conservação e possíveis alternativas econômicas com potencial de conciliar a conservação da biota com a geração de renda. Realizamos este estudo de janeiro de 2021 a março de 2023, a partir de relatos de experiências dos autores, registros de campo para a produção da ção "Parques de Minas, Olhares Gerais" e revisão de literatura.Constatamos que comunidades locais, comumente, pressionam essas unidades de conservação, reivindicando o uso das terras para fins econômicos, uma vez que a criação dos parques restringiria, em tese, seu acesso a recursos naturais, queantes eram importantes fontes de renda. Consideramos imprescindível que esses conflitos recebam mais atenção, para redução das tensões existentes entre as áreas protegidas e as comunidades locais. Modelos de conservação exitosos indicam o ecoturismo aliado Ã  preservação como uma importante alternativa, capaz de beneficiar o conjunto da comunidade ao invés de grupos econômicos específicos.

La existencia de la filosofía de la India hoy está fuera de dudas. Han sido Fernando Tola y Carmen Dragonetti, indólogos sanmarquinos, quienes dedicaron toda una vida a dar razones de esta afirmación, plasmada en sus cuatro tesis sobre la existencia de la filosofía de la India. En ese marco, seguir tratando temas clásicos de la filosofía como el mundo, el conocimiento y la verdad nos permite ver la diversidad de enfoques dentro de esta gran tradición de pensamiento. Por ese motivo, en lugar del posible equívoco del singular «filosofía de la India», como si fuese una visión homogénea respecto a los temas y problemas, en realidad estamos en presencia de una diversidad de puntos de vista (darśana) o escuelas.
RECOMMENDATIONS FOR DESIGNING AN ADAPTIVE VIBRATING MILL IN CONCENTRATED FEED PREPARATION TECHNOLOGY

Recommendations for the construction of an adaptive vibration mill for the preparation of concentrated feed

At the present stage of development of the processing industry of agro-industrial production is closely connected with the search and implementation of promising technical and technological solutions that provide the possibility of efficient use of energy consumed.

One of the main directions of processing of agricultural products is its grinding. Grinding of grain ingredients is an important operation in the technological process of production of micro-fertilizers for dry feed, herbal flour, premixes, feed, mineral components for animal feed, as well as for the treatment of dependent mineral fertilizers.

Today, the grinding process is carried out mainly by crushing and grinding machines, which are not effective enough, due to significant wear of working bodies (in hammer, rotary crushers), low specific productivity (in ball and jet mills), relatively high power consumption per drive and other factors. A progressive type of grinders are vibration mills, which have high specific productivity, low energy consumption and wide technological capabilities - adjustable grinding tone.

This scientific article provides a constructive scheme of the adaptive vibration mill, in which the vibration field provides the lifting of part of the load(grinding bodies and crushed material) and with the help of a transport-reloading device performs its continuous controlled movement from one grinding chamber to the second, thereby ensuring circulation-spatial movement of the medium in which the grinding process occurs as a result of impact interaction of grinding bodies and crushed material.

The current state of agricultural production requires the development and implementation of innovative equipment, the basis of which is mechatron systems and automated control systems, therefore, the schematic diagram of an adaptive vibration mill for grinding components of concentrated feed given in the floor is a priority for creating vibration mills.

The scientific article provides recommendations for the calculation and design of the main units of the adaptive vibration mill with spatial-circulation movement of the technological medium.
FEATURES OF THE GRAIN MICRONIZATION PROCESS
Authors: Polievoda Yurii , Revva Viktor , Tverdokhlib Ihor
Published: May 2024

Effective means of reducing the loss of grain products are its processing and bringing it to the condition humidity by means of heat treatment. One of these methods - micronization of grain allows to reduce non-productive energy consumption, improve the quality of the finished product, it can be considered the most promising for thermal processing of grain in the food industry. The purpose of this study is to increase the energy and quality efficiency of the grain micronization process by studying the features of its flow in various technological conditions. The analysis of sources devoted to the issue of grain micronization shows that the main direction of research is the substantiation of process parameters and the development of new technological methods. To successfully conduct research in this direction, it is necessary to understand all the features of the elements of this system (installation and grain) that arise during the implementation of the micronization process. The nature of the interaction between the material and IR radiation largely depends on the optical characteristics of the grain. Optical properties of materials are usually characterized by their transmission, absorption and reflection capacity. The optical characteristics of materials depend on a number of factors, such as structure, humidity, process temperature, etc. The properties of vitreous and floury grains are particularly different. The effect of grain structure especially affects the reflection coefficients of radiant energy. So, for the same wavelength of 0,9-1,3 μm and moisture content of 5-30%, for floury wheat grains it is equal to 0.68-0,73, while for vitreous grains it has a value of 0,48-0,54. There cannot be a universal approach to determine the rational parameters of the grain micronization process. In each case, there must be specific approaches to determine the rational parameters of the process. This will significantly increase the energy and quality efficiency of the grain processing process.
MODELING AND IMPROVEMENT OF ANISOTROPIC STRENGTHENING OF ORTHOTROPIC CRYSTALLINE MATERIALS
Authors: Zalizniak Roman
Published: May 2024

Sheet material subject to stamping, as a rule, has an anisotropy of mechanical properties due to the brand of the material and the technological modes of its production. The anisotropy of the mechanical properties of the workpiece material can have both a positive and a negative effect on the steady course of technological processes of pressure metal processing. In the processes of plastic deformation, the initial anisotropy of the mechanical properties changes and depends on the processing modes.

When analyzing the technological processes of processing anisotropic metals by pressure, the initial anisotropy of the mechanical properties is mainly taken into account. Accounting for the influence of the initial anisotropy is carried out within the framework of an ideal plastic or isotropic body that is being strengthened. However, these assumptions do not allow us to estimate the change in anisotropy of mechanical properties during plastic processing.

Most of the existing theories of anisotropic strengthening of an initially isotropic and anisotropic body are based on isotropic expansion and movement of the load surface in the stress space and differ from each other in the approaches to describing the movement of the center of the load surface, which can be specified in the form of finite and differential relations. They are designed for small elastoplastic deformations.

The article gives the main ratios that must be used in the analysis of cold stamping processes of orthotropic anisotropically strengthening materials and proposes mathematical models of anisotropic strengthening of orthotropic crystalline materials. The deformation intensity value and components of the strain tensor in the main axes of anisotropy are used as strengthening parameters, and the accumulated amount of damage is also taken into account.
INVESTIGATION THE IMPACT OF THE CONSTRUCTIVE PARAMETERS OF THE WORKING BODY THE TILLAGE MACHINE ON THE ENERGY INTENSITY AND QUALITY OF SOILTILLAGE
Authors: Trukhanska Olena
Published: May 2024

The study of the technological process and design parameters of the tipping working tool was carried out. The most favorable conditions for plants are created when the cultured soil layer is differentiated by its structural composition. At the same time, clods with a size of 5 to 20 mm should prevail in the surface layer of the soil, and in the seed bed - from 0.25 to 10 mm.

Means of mechanization of soil cultivation in systems of zero, minimum and zero tillage, which provide the necessary conditions for growing agricultural crops, were analyzed.

It was established that in order to obtain a fine-grained structure of the soil in the area of seed placement, it is not necessary to grind it intensively and thereby increase the energy intensity of the process. The necessary structure can be obtained by combining the operation of grinding the soil and its fractional distribution along the processing depth.

The influence of the geometric parameters of the slope of the inclined disintegrator according to quality and energy indicators of zero tillage. A high concentration of these row crops leads to the accumulation of harmful weeds, diseases and pests.

It was determined that the use of tillage technologies on sloping fields, which are adapted to flat conditions and do not take into account the peculiarities of the relief, leads to intensive development of erosion processes. Modern tools for the main cultivation have their shortcomings: the chisel does not grind the soil enough and does not cut the roots of the weeds; a plow sole is created with a flat cutter; the plow not only creates a footing, but also covers the crop residue, turning the soil over, creating conditions for water and wind erosion. One of the ways to improve the quality of the main tillage will be the use of loose plows with inclined working bodies, which ensure high-quality loosening over the entire width of the tillage unit, eliminate soil compaction and leave stubble on the field surface.

Published: May 2024

Mathematical modeling plays a crucial role in understanding the interaction between the tiller paw and the soil. In this article, we explore some of the mathematical models used to describe this interaction. These models include the kinematic wave equation, which describes paw motion as a wavelike disturbance through the soil, and the Reynolds equation, which describes paw motion through forces acting on it. Also discussed are the soil deformation equations, Froude number, and Mohr-Coulomb failure criterion, which describe soil deformation, the relative importance of inertial and gravity forces, and soil shear strength, respectively. Using these equations, we can better understand the various physical and mechanical forces that play an important role in the interaction between the tiller foot and the soil, leading to improved design and performance of tillers.

The use of these mathematical models provides a more complete understanding of the complex interaction of the cultivator paw with the soil. They help predict the behavior of the soil under different conditions and give insight into how to optimize the cultivator design for better performance. This knowledge can be used to develop new cultivator designs, resulting in more efficient and effective tillage. In summary, mathematical modeling is a vital tool for understanding the interaction between the tiller paw and the soil, providing valuable information on how to improve tillage efficiency and effectiveness.

In addition, the mathematical models discussed in this paper can be used to improve our understanding of soil mechanics, which is critical for a variety of applications, including agriculture, construction, and environmental protection. By improving our understanding of the interaction between the tiller paw and the soil, we can develop more efficient and effective tillage methods that will lead to better yields, improve soil condition and reduce soil erosion. Ultimately, the development of accurate and reliable mathematical models of tiller-soil interactions will play a key role in the sustainable use and management of our valuable soil resources.

An Anomaly Detection System for Vampire Attacks Crisis in Wireless Sensor Networks
Authors: Kannan G , Indragandhi K , Midhat Jan
Published: May 2024

One of the major crises to be addressed by Wireless Sensor Networks (WSN) is vampire attacks which disable the network connection by consuming node energy unnecessarily. Energy efficiency plays the prominent role in wireless sensor networks. In these networks many attacks are possible for energy draining at each sensor node. The proposed work investigates various resource consuming attacks called vampire attacks namely carousel and stretch attack which rapidly drain energy of a WSN node. It causes permanent disabling of WSN. These attacks are not protocol specific and it is hard to find out. The proposed work suggests Modified-PLGPa protocol to identify and remove the attacks to enhance network longevity. This protocol helps to reduce the effect of vampire attack by decreasing the energy loss caused by unwanted packet transmission in the network routing. The performance of the Modified-PLGPa protocol was demonstrated with the different types of vampire attack i.e, carousel attack and stretch attack. The experimental simulation result shows that overall residual energy and packet delivery ratio have been improved remarkably.

Published: May 2024

The current document presents a fresh method for addressing the optimization challenges concerning fuel mixtures in the production of Biodiesel. Given the rising concerns over diesel emissions and the associated expenses, there's a growing interest in exploring alternative fuel options. Traditional desulphurization methods are time-consuming and require substantial financial investments. Conversely, Biodiesel offers a promising solution as it's derived from renewable resources and is environmentally sustainable. This study introduces an enhanced genetic algorithm that assesses the proportions of components within a fuel mixture blend, aiming to create optimal combinations for Biodiesel production. Apart from cost considerations, the density of the fuel, a key physicochemical characteristic, is pivotal in determining its suitability for widespread use and commercialization. Rigorous experimentation has resulted in highly precise Biodiesel blends, suggesting an optimal fuel solution for each specific set. For instance, in Set 1, Biodiesel was composed of 75.031% diesel and 24.969% biodiesel, with a mixture cost of 1.6975 €/l and a density of 0.8355 g/ml. In Set 2, the fuel mixture consisted of 75.016% diesel and 24.984% biodiesel, with a cost of 1.6977 €/l and a density of 0.8366 g/ml. Notably, the new Biodiesel fuels are significantly cheaper, costing 15.13% less (Set 1) and 15.12% less (Set 2) than diesel (priced at 2.0000 €/l) and are proposed between 1.5 * 109 evaluated biodiesel mixtures.

In addition to the already present video and voice services, newly created technologies and applications, such as internet services, interactive gaming, and telemedicine, are adding to the already tremendous amounts of traffic and vulnerability generated. The semiconductor laser chaos generation is now being utilized to improve data security and protect data from theft during its transmission from the transmitter to receivers a means of concealing multi-level data signals to address these concerns regarding data security. The incoming signals are concealed before the optical chaotic signal's transmission via the optical fiber medium by our suggested method, which makes use of the double delay feedback technique to create the optical chaotic signal. The additive chaos masking system is utilized to execute the mixing of incoming signals with chaos. This method demonstrates several valuable qualities, including simplicity and the ease with which a message may be recovered. To explore the propagation concerns that are related to secure signal transmission, chaotic data, which is a combination of incoming signals and random noise, is transmitted via the medium of optical fiber. To properly regulate the linear impairments of optical fiber, which is required for the efficient transmission of a secure signal, the plan is put into action for long-haul communication to facilitate the long-distance transfer of data. Adjustments are made to the parameters on both the transmitting and receiving ends to achieve synchronization between the two processes. This is done in such a way that the received signal may be restored to its original state by subtracting the broadcast signal from the same chaos on the receiving side. Obtaining Q-factors allows the method to be evaluated for a variety of optical fiber cable lengths, during which the Q-factors serve to evaluate the quality of the signal that is received.

Психолого-педагогічна підтримка та адаптація дітей з порушеннями зору в теперішній час є однією з найважливіших проблем навчально-виховної роботи. Проживаючи тривалий час в умовах воєнного стану та замкнутого простору, діти не мають змоги самостійно й повноцінно включатися в соціальне життя. Питання соціалізації дітей дошкільного віку актуалізуються з віком дитини, що входить у новий простір життя — дошкільне дитинство, у якому формується сприйняття довкілля та оточуючих, чуттєво-образні способи пізнання, набуття соціального досвіду. Соціалізація дітей з порушеннями зору здійснюється за трьома основними напрямами: підвищення соціально-психологічної компетентності дітей, тобто здатність дітей з порушеннями зору ефективно взаємодіяти з навколишніми людьми в системі міжособистісних відносин; розширення побутового й соціального досвіду дітей з порушенням зору, для цього необхідно пов'язувати будь-які теоретичні знання з практикою, навколишньою дійсністю; формування у дітей з порушеним зором сприйняття своєї соціальної ролі й ставлення до навколишніх, успішної соціально-психологічної адаптації.
Transjugular intrahepatic portosystemic shunt for recompensating decompensated cirrhosis?
Authors: Karagiannakis Dimitrios S
Published: May 2024

Transjugular intrahepatic portosystemic shunt (TIPS) is a medical procedure that has been used to manage variceal bleeding and ascites in patients with cirrhosis. It can prevent further decompensation and improve the survival of high-risk decompensated patients. Recent research indicates that TIPS could increase the possibility of recompensation of decompensated cirrhosis when it is combined with adequate suppression of the causative factor of liver disease. However, the results of the studies have been based on retrospective analysis, and further validation is required by conducting randomized controlled studies. In this context, we highlight the limitations of the current studies and emphasize the issues that must be addressed before TIPS can be recommended as a potential recompensating tool.
Kinesin 26B modulates M2 polarization of macrophage by activating cancer-associated fibroblasts to aggravate gastric cancer occurrence and metastasis
Authors: Huang Lian-Meng , Zhang Ming-Jin
Published: May 2024

BACKGROUND

The regulatory effects of KIF26B on gastric cancer (GC) have been confirmed, but the specific mechanism still needs further exploration. Pan-cancer analysis shows that the KIF26B expression is highly related to immune infiltration of cancer-associated fibroblasts (CAFs), and CAFs promote macrophage M2 polarization and affect cancers’ progression.

AIM

To investigate the regulatory functions of KIF26B on immune and metastasis of GC.

METHODS

We analyzed genes’ mRNA levels by quantitative real-time polymerase chain reaction. Expression levels of target proteins were detected by immunohistochemistry, ELISA, and Western blotting. We injected AGS cells into nude mice for the establishment of a xenograft tumor model and observed the occurrence and metastasis of GC. The degree of inflammatory infiltration in pulmonary nodes was observed through hematoxylin-eosin staining. Transwell and wound healing assays were performed for the evaluation of cell invasion and migration ability. Tube formation assay was used for detecting angiogenesis. M2-polarized macrophages were estimated by immunofluorescence and flow cytometry.

RESULTS

KIF26B was significantly overexpressed in cells and tissues of GC, and the higher expression of KIF26B was related to GC metastasis and prognosis. According to in vivo experiments, KIF26B promoted tumor formation and metastasis of GC. KIF26B expression was positively associated with CAFs’ degree of infiltration. Moreover, CAFs could regulate M2-type polarization of macrophages, affecting GC cells’ migration, angiogenesis, invasion, and epithelial-mesenchymal transition process.

CONCLUSION

KIF26B regulated M2 polarization of macrophage through activating CAFs, regulating the occurrence and metastasis of GC.

The screening of colorectal cancer (CRC) is pivotal for both the prevention and treatment of this disease, significantly improving early-stage tumor detection rates. This advancement not only boosts survival rates and quality of life for patients but also reduces the costs associated with treatment. However, the adoption of CRC screening methods faces numerous challenges, including the technical limitations of both noninvasive and invasive methods in terms of sensitivity and specificity. Moreover, socioeconomic factors such as regional disparities, economic conditions, and varying levels of awareness affect screening uptake. The coronavirus disease 2019 pandemic further intensified these cha-llenges, leading to reduced screening participation and increased waiting periods. Additionally, the growing prevalence of early-onset CRC necessitates innovative screening approaches. In response, research into new methodologies, including artificial intelligence-based systems, aims to improve the precision and accessibility of screening. Proactive measures by governments and health organizations to enhance CRC screening efforts are underway, including increased advocacy, improved service delivery, and international cooperation. The role of technological innovation and global health collaboration in advancing CRC screening is undeniable. Technologies such as artificial intelligence and gene sequencing are set to revolutionize CRC screening, making a significant impact on the fight against this disease. Given the rise in early-onset CRC, it is crucial for screening strategies to continually evolve, ensuring their effectiveness and applicability.

Published: May 2024

Background: Impacted teeth are teeth that cannot be indicated in their physiological position in the expected  period. Impacted mandibular third molar (IMTM)is the most common tooth to be impacted. Impaction of the tooth may be accompanied by complications such as pain, swelling, caries, bone loss, and inferior alveolar canal  pathology. Because of possible complications of the IMTMs,a surgical extraction may be necessary. Moreover, knowing the pattern of IMTMs can lower the possibility of complications after the surgery.This research aims to  evaluate the impaction pattern of the IMTMs in the population of patients referring to the Dentistry faculty of the Guilan University of medical sciences clinic.
Methods: In this retrospective analytic cross-sectional study 98 radiographs were gathered and the angulation, depth, and side of impactions, inferior alveolar canal pathology, and decay existence were evaluated. Then each factor was assessed based on age and gender. Analyzing data was done using IBM Statistical Package for the Social Sciences (SPSS) Statistics for Windows, version 21 (IBM Corp., Armonk, N.Y., USA).
Conclusion: Mesioangular pattern and level B of impaction depth were the most prevalent position of the  IMTMs. Most cases had unilateral impaction and right-sided impaction was more frequent than left-sided.
