Although some of these are used in Ethnomedicine as well, their excessive use may result in DNA damage and mutation that come out in the form of cancer. This study was aimed at estimating the genotoxic potential of Allium sativum, Trachyspermum, and Zingiber officinale, their Ethanolic and water extracts were prepared in different concentrations. Method: Lymphocytes from whole blood were separated through centrifugation technique and treated with plant extracts. For the identification of DNA strand breakage and genotoxicity the Comet assay and slide analysis were performed. Results: The damage in cell membrane disclosed the cytotoxic effect at the highest concentration used while the Genotoxic effect and the DNA damage were poorly expressed.
The Image of the Family among the Victims of Rape in Algeria
Authors: Bouziidi Houda 
Published: December 2023

Post-traumatic clinic research showed that a highly traumatic event, such as rape, is able to upset the balance of the victim and her family. Indeed, as a result of rape, feeling like the shame, the guilt and the inability to cope with the each other's gaze arise among families of the victims, particularly in some cultural contexts as is the case in Algeria. We recorded attitudes as the refusal and family abandonment among families of the victims, which made them more vulnerable and urged them to develop a chronic PTSD. It seems, in fact, that the negative attitudes of families are the cause of great suffering for the victims. This is the finding that we made during our clinical work with a dozen victims of rape in Algeria. In this article, I try to identify and analyze, through the dreamlike stories provided by only three of these victims, in our clinical meetings, the multi-faceted or even images related to the representation of the family circle in the context of trauma.
Coherence Coefficient of Core Competencies used Predict Job Performance for Medical Employees in a Hospital
Authors: Chien Tsair Wei
Published: December 2023

Background: To investigate whether coherence coefficients of core competencies can predict job performance for rehabilitation-related therapists in a hospital. Methods: Rehabilitation-related therapists (n = 133) from 3 hospitals in southern Taiwan were enrolled for this competency survey using the Web Competencies Assessment System developed by 1111 Job Bank in Taipei. A t test was used to examine mean differences between the system's 15 core competencies and demographic variables. Regression analysis was used to inspect the association between the personal coherence coefficient of the core competencies and job performance. Result: The participant's core competencies were Job Control, Conscientiousness, Executive Ability, Self-Enhancement, Stress Tolerance, Optimism, and Customer Relationships. Their scores were higher than those of the reference group (nurses). The coherence coefficient can significantly predict job performance. Conclusion: The coherence coefficients of core competencies associated with their own worksite were beneficial for recruiting and hiring new employees, and for career development. The coefficient of core competencies can be used to promote and train future rehabilitation department supervisors.

Authors: Research Team Karamoja–Turkana Community
Published: December 2023

In the Karamoja and Turkana border regions of Uganda and Kenya, there is widespread violence including armed robbery, rape, and human rights abuses, yet community complaints about failures of governance remain largely unaddressed. This Policy Briefing highlights how different insecurities reinforce one another in ways exacerbated by the international border. It stresses the need for fulfilment of the two governments’ commitments to cross-border solutions, and suggests that international policy actors can help communities gain leverage with governments towards building trustworthy and effective peace and security institutions.

El objetivo fue evaluar el aporte exógeno de progesterona, y la influencia del cuerpo lúteo (CL) al iniciar protocolos de sincronización de estros en ovejas, por 6 y 11 días, sobre las variables reproductivas. Las ovejas fueron presincronizadas para obtener un CL inmaduro o funcional al iniciar el periodo de sincronización a evaluar. La presentación de estros fue baja en tratamientos cortos; esto desencadenó discrepancias (p < 0.05) en porcentaje de gestación de tratamientos de 6 días y los tradicionales de 11 días. El día del estro la concentración de esteroides fue diferente, progesterona fue mayor en tratamientos cortos; mientras que estradiol fue menor en el tratamiento corto con CL. La presencia de un CL inmaduro o funcional al iniciar tratamientos para sincronizar estro convencionales no modifica la expresión de las variables reproductivas; sin embargo, en tratamientos cortos la expresión se ve afectada. Es importante el uso de ultrasonografía para corroborar lo que pasa a nivel ovárico.

Published: December 2023

The use of chitosan-iodine (Cs-I) complexes can be a good strategy to improve the nutraceutical quality and the concentration of I in the edible part of crops. The objective of this study was to evaluate the effects of biofortification via foliar of I in a complex with Cs on the nutraceutical quality of jalapeño pepper fruits. The treatments were the following: absolute control, 1% Cs and I complex (5, 10, 15, 15, 20, and 25 mg L–1) + 1% Cs. The application of the 15 mg L–1 complex of Cs-I improved the nutraceutical quality of the fruits, in contrast to the application of 1% Cs individually. In addition, as the dose of the Cs-I complex increases, the accumulation of I in the fruit increases. The use of the Cs-I complex is an alternative to modulate the nutraceutical quality and I content in jalapeño pepper fruits.

Unidade e fragmentação do habitus
Authors: Silva Elizabeth , Miraldi Juliana , Abdalla Julia
Published: December 2023

Este artigo examina a noção unitária de habitus presente nos primeiros trabalhos de Bourdieu e sua transformação ao longo da carreira sociológica do autor, acompanhando-a até as concepções posteriores de um conceito de habitus fragmentado para examinar a relacionalidade e as mudanças sociais contemporâneas. O percurso do conceito de habitus em Bourdieu mostra que as interações entre habitus e campo exigem um crescente trabalho de integração dos indivíduos conforme a vida social se torna mais diferenciada. O artigo argumenta em favor da necessidade da sociologia investir em análises de campo para avançar nas explorações do habitus e reconhecer a potencial flexibilidade do conceito. Sugere-se que a sociologia adote a noção psicanalítica de “posicionar-se nos espaços” (standing in spaces) (e noções associadas de “liminaridade” e experiências em posições intersticiais) para o desenvolvimento produtivo da noção de habitus fragmentado e para aprimorar propostas que veem o social com uma história passível de mudança pelos seres humanos.
REINTERPRETATION OF ECOLOGICAL VERSES TO IMPLEMENT ECO-ETHICS IN ISLAMIC EDUCATION
Authors: Al Walidah Iffah , Husaini Irpan
Published: December 2023

Modern commentators and intellectuals have begun to explore studies that link the position of humans and plants as a unity of living things created by God's holy creation. Generally, when talking about ecology, humans are used as the main character in caring for nature. Many verses in the Qur’an talk about how the human spirit is metaphorized with ecological elements. As a religious principle, Islam describes monotheism as a syajarah thayyibah whose roots reach the ground and its branches reach the sky (QS: 14:24). This research is qualitative descriptive-analytical research. Researchers will collect data related to this research. Furthermore, the data was analyzed to find a solution with the Maqashidi Interpretation method then relate it to how ecological ethics lives in Islamic education. This research focuses on QS. Al-Fatihah: 1 and Ar-Rum: 30. The result of this research show that the redaction of rabb al-'alamin in QS. Al-Fatihah shows the closeness between Rabb and 'alamin. On the other hand, the Qur’an explains that natural damage occurs due to human activities (QS.30:41). The implied meaning in the two verses is that humans, nature, and other creatures need each other and are encouraged to respect each other. An understanding of comprehensive ecological verses will have a good effect on ecological ethics in the world of Islamic education. The educational process provides knowledge about how nature works and how to interact with the natural world. The growing eco-Islamic movement utilises Islamic educational institutions, both traditional and modern as centres of environmental learning and teaching. The Islamic educational landscape remains essential in broadcasting environmental narratives that present ethical and educational visions relevant to contemporary ecological movements.

AIM: To evaluate the etiological and demographic characteristics and treatment processes of patients with trauma-induced elevated intraocular pressure (IOP).

MATHERIAL AND METHOD: We retrospectively analysed 191 patients with elevated IOP after trauma between 1990 and 2018. Demographic characteristics, type of trauma, cause of glaucoma, lens status, visual acuity, IOP, other ocular findings, medical and/or surgical treatments and follow-up periods were recorded.

RESULTS: A total of 148 (77.5%) males and 43 (22.5%) females with a mean age of 29.68±19.47 years were analysed. Mean follow-up period was 158±23.73 months. The type of trauma was blunt in 171 patients (89.5%) and open in 20 patients (10.5%). The mean interval between trauma and IOP elevation was 78 days (3 days-5 years). Glaucoma was due to angle regression in 89 (46.6%), hyphema in 78 (40.8%), lens-related in 24 (12.6%) and other causes in 3 (1.54%) patients. Lens damage, lens-related IOP elevation and need for surgical intervention were more common after open injuries. 72% of the patients were able to achieve appropriate IOP with observation and medical treatment alone without surgery. Trabeculectomy was the most preferred effective surgical method in both trauma groups.

CONCLUSION: The development of glaucoma after ocular trauma is an essential factor affecting visual prognosis. Early diagnosis and treatment might be challenging in proportion to the severity of ocular involvement. However, not all IOP elevations may cause glaucomatous damage, transient IOP elevations could be monitored without medication. In our study, the frequency of posttraumatic IOP elevation was higher in men and young people. This might be related to more trauma exposure in the indicated population. Blunt traumas cause IOP elevation more frequently. In contrast, the need for glaucoma surgery is more frequent after open injuries. Angle recession is the most common cause of posttraumatic glaucuma. Therefore, angle assessment is necessary in all possible cases. The status of the lens after trauma will affect the prognosis and choice of surgery. Regular follow-up is crucial for the detection of secondary glaucoma since IOP elevation may develop in the late post-traumatic period.

Modeling stress relaxation under conditions of cyclic deformation of nonlinear viscoelastic materials using the Heaviside function
Authors: Pavlyuk Yaroslav
Published: December 2023

The problem of calculating the stress relaxation of nonlinear viscoelastic materials under conditions of cyclic deformation is considered, which is given in the form of cyclic alternations of loading and unloading of equal amplitude in rectangular cycles, while the duration of half-cycles of loading and unloading coincide. The load program is implemented in the form of a sequence of elementary loads, which is specified using Heaviside's unit functions. A nonlinear creep model with time-independent nonlinearity of the Rabotnov model is used to describe the deformation process. The heredity kernels are given by Rabotnov's fractional-exponential function.

Authors: Trach Volodymyr , Podvornyi Andrii , Zhukova Natalia
Published: December 2023

Based on the modified Hu-Washizu variational principle, a three-dimensional system of homogeneous linearized differential equations of stability of non-thin anisotropic cylindrical shells is obtained. The anisotropy type of shells is characterized by one plane of elastic symmetry. Reducing the system to a one-dimensional one is carried out using the Bubnov-Gal'orkin method, which approximates the functions of unknown systems of equations along the generatrix and takes into account their periodicity in the circumferential direction. The numerical solution of the obtained one-dimensional system of equations is carried out using the discrete orthogonalization method.

The problem of stability of a non-thin anisotropic cylindrical shell for a different number of cross-laid composite layers against the action of axial pressure is solved. The nature of the dependence of critical forces on the number of layers is analyzed.

Published: December 2023

The issue of demining reservoirs, rivers and sea raids and ports, which is relevant for Europe during the period of active deployment of military confrontations on its territory, is considered. Only in the maritime territorial waters of Ukraine and in the water areas of its freshwater reservoirs and rivers, during the year of the war, the enemy laid up to a thousand different mines. Demining of the Ukrainian water spaces of the sea, reservoirs and rivers is an important social and economic problem, the solution of which does not tolerate delay and waiting for the full end of hostilities.

            The purpose of the work is the development of principle schemes for optimizing the spatial movements of search and mine clearance vessels and the creation of algorithms for calculating the precise coordinates of the spatial location of floating, anchor and bottom mines by means of kinematic design.

The research methodology was the application of the theory of mapping coordinates and trajectories of spatial movements of moving objects by means of graphic geometry, taking into account the specifics and dynamic features of kinematic design.

A schematic diagram of the spatial location of search trawlers and UAVs or auxiliary search floats when searching for mines has been developed. Mathematical dependencies have also been established for the precise calculation of the coordinates of detected mines based on the data of the applied theory and kinematic design schemes. For the search for floating mines, the optimal trajectory of search movements of unmanned aerial vehicles along the Archimedean spiral is proposed. The optimal number of aircraft that search for floating mines at the same time has been determined. As one of the most effective options for the disposal of mines, their detonation with warheads dropped from an aerial liquidator drone has been proposed.

The main result of the study is the creation of a methodology for calculating the refined coordinates of the search for floating, anchor and bottom mines in combination with the optimization of the trajectories of the search movements of aerial and floating search vehicles along the Archimedean spiral. This ensures not only a 25-30% increase in surveyed and demined areas, but also a proportional saving of fuel due to a reduction in the number of crossings of search trawlers. It has been established that at speeds of spatial movements of search aircraft or auxiliary floating means of 5÷5.5 m/s, using the proposed search scheme, it is possible to survey up to 6 square kilometers of sea water area every hour. At the same time, it is possible to save up to a third of the cost of expensive fuel due to the reduction of movements of the trawler boat.
Increasing the adaptability of laser technological systems
Authors: Dubniuk Viktor , Kotliarov Valeriy
Published: December 2023

Modern laser technological systems operated at machine-building enterprises are usually highly specialized, intended for the implementation of one single operation. On the one hand, this is expedient because it significantly increases the efficiency of using such equipment and limits the number and cost of auxiliary technological equipment. On the other hand, sometimes it is necessary to expand the technological capabilities of the equipment in order to obtain somewhat specific characteristics of the processed workpieces and increase the adaptability of the equipment to the designed technological operations. The purpose of this study was to determine the main needs for technological equipment of laser technological systems for surface treatment, which should provide opportunities to expand the range of processed workpieces by configuration and expand the list of processed materials. Such an increase in the adaptability of the technological system should provide opportunities to increase the flexibility of their application. In order to achieve the set goal, it was determined that in order to obtain accurate physical and mechanical parameters of the processed parts, it is necessary to clearly withstand and control the heating temperature of the surface of the workpiece at different points of its surface and ensure the time of exposure to each individual area. These two characteristics will depend on the physical and thermal characteristics of the material itself and the configuration of the processed workpiece (thickness, width, length, volume, presence of pointed edges, etc.).
Experimental studies of the influence of biaxial bending on the crack resistance of reactor pressure vessel steel
Authors: Sydiachenko Viacheslav , Pokrovskyi Volodymyr
Published: December 2023

Background: to assess the residual life of nuclear reactor hulls in Ukraine, normative temperature dependences of the crack resistance of hull steels obtained on standard samples with a deep through crack under plane strain conditions are used. However, it is known that the thickness of the wall of the reactor body is subject to biaxial loading, which affects the value of the crack resistance characteristics. Therefore, in order to substantiate the possibility of lengthening beyond the design resource of VVER-1000 reactor hulls, an experimental study of the effect of biaxial load on the crack resistance characteristics of hull reactor steel 15X2NMFAA is relevant. Objective: development of an experimental technique and investigation of crack resistance under biaxial loading on small-sized samples in the the brittle-ductile transition temperature range of reactor steels. Methods: on the basis of numerical and engineering calculations, a specimen was developed, the corresponding additional equipment for its tests under biaxial loading on a uniaxial servo-hydraulic machine. The influence of biaxial bending on the fracture toughness of reactor steel 15X2NMFAA was experimentally investigated. Results: the results obtained on cruciform specimen are calculated according to the ASTM 1921 standard and plotted on the Master curve (temperature dependence of fracture toughness). The analysis showed that the data on crack resistance obtained on samples with "short" (a/W=0.1...0.2) linear and surface semi-elliptical cracks exceed the upper limit of the confidence interval of the Master curve, and biaxial loading of cruciform specimen reduces crack resistance compared to uniaxial loading.
Elements of the theory of designing manipulators from composite materials for ground robotic complexes for special purposes
Authors: Strutinsky Vasiliy , Hurzhiі Andriy
Published: December 2023

Elements of the theory of designing manipulators from composite materials intended for use in ground-based robotic complexes for special purposes have been developed. Circuit solutions of manipulators and constructive execution of their main components and elements are proposed. Special hinges and remote drives for moving links of manipulators have been developed. To ensure the required static and dynamic characteristics, special mechatronic modules are implemented in the form of geared motors that are outside the manipulators. Control systems of geared motors are implemented on the basis of artificial neural networks using the results of mathematical modeling of statics and dynamics of manipulators by helical calculus methods. The developed manipulators significantly increase the functionality of ground robotic complexes when they work with dangerous objects.
To improve the reliability and increase the service life of rolling bearings
Authors: Sumonyuk Volodymyr
Published: December 2023

Rolling bearing units are important in the technology of any purpose, namely their properties - reliability, long-term functioning, often subject to a one-time application of lubricating material. When designing and developing the technological process of carrying out assembly operations of bearing assemblies, we do not take into account the quality condition of rolling bearings, that is, we do not conduct input control. From the economic point of view, this is justified, the ethics of trusting the supplier also works. The conducted studies showed that a significant part of bearing failures is related to the input quality of the bearing condition. During the research, the bearings were washed in kerosene, dried, briefly run-in, and re-lubricated. Metal particles were found, which are mainly the products of activation, namely, the result of the initial running-in of the bearing elements.Additional preparatory work carried out before starting the operation of the bearings cannot harm their further, more efficient operation.

Published: December 2023

Remote Sensing and Geographic Information System are recognized as crucial instruments for conducting geographical and geospatial research. RS and GIS technology was employed to assess the morphological Characteristics of the Kasura River Watershed situated within the Parbhani and Jalna Districts of Maharashtra, India. The entire drainage area of the Kasura River basin measures 490.13 square kilometers (km2). Various morphometric characteristic were calculated and examined, encompassing linear features such as stream number, stream order, mean stream length, stream length, and stream length ratio, areal attributes including elongation ratio, circularity ratio, form factor, constant of channel maintenance, drainage density and drainage texture and relief characteristics such as relief, relief ratio, maximum relief, ruggedness number, relative relief, and length of overland flow. These findings underscore the significance of employing morphometric analysis in watershed assessment, offering a quantitative method for characterizing the surface attributes of a drainage pattern and yielding valuable insights into the topography and runoff dynamics of the region.
Correlation of Pseudomonas aeruginosa Phage Resistance with Numbers and Types of Antiphage Systems
Authors: Burke Kevin A. , Urick Caitlin D. , Mzhavia Nino , Nikolich Mikeljon P. , Filippov Andrey A.
Published: December 2023

Phage therapeutics offer a potentially powerful approach to combat multidrug-resistant bacterial infections. However, to be effective, phage therapy must overcome existing and developing phage resistance. While phage cocktails can reduce this risk by targeting multiple receptors in a single therapeutic, bacteria have mechanisms of resistance beyond receptor modification. A rapidly growing body of knowledge describes a broad and varied arsenal of antiphage systems encoded by bacteria to counter phage infection. We sought to understand the types and frequencies of antiphage systems present in a highly diverse panel of Pseudomonas aeruginosa clinical isolates utilized to characterize novel antibacterials. Using web-server tool PADLOC (Prokaryotic Antiviral Defense Locator), putative antiphage systems were identified in these P. aeruginosa clinical isolates based on sequence homology to a validated and curated catalog of known defense systems. Coupling this host bacterium sequence analysis with host range data for 70 phages, we observed a correlation between existing phage resistance and the presence of higher numbers of antiphage systems in bacterial genomes. We were also able to identify antiphage systems that were more prevalent in highly phage-resistant P. aeruginosa strains, suggesting their importance in conferring the resistance.
Serum Amyloid A as a biomarker in Inflammatory Bowel Diseases
Authors: Stute Marie , Kreysing Martin , Zorn Markus , Michl Patrick , Gauss Annika
Published: December 2023

The acute phase protein Serum Amyloid A (SAA) is synthesised by the liver in response to inflammatory stimuli. Previous studies have revealed that SAA may be a better predictive marker for the course of inflammatory bowel disease (IBD) compared to C-reactive protein (CRP). Hence, this retrospective monocentric study evaluated whether SAA correlates with biomarkers like faecal calprotectin (FC), CRP, the Neutrophil to Lymphocyte ratio (NLR) and clinical disease activity of IBD patients. Serum samples from the IBD outpatient clinic of the University Hospital Heidelberg were analysed for their SAA concentrations if a FC concentration measurement was available from 14 days before or after collection of the serum sample. 306 serum samples from 265 patients (166 with Crohn’s disease, 91 with ulcerative colitis, 8 with IBD unclassified) met the inclusion criteria. There was a significant positive correlation between SAA and FC, CRP, the NLR and the Simple Clinical Colitis Activity Index. The cut-off for SAA serum concentration at 4.55 mg/l achieved a sensitivity of 57.5% and a specificity of 69.7% for the detection of active inflammation in IBD. SAA may be used as an additional biomarker in the disease monitoring strategy of IBD patients, especially in patients with low CRP concentrations.
International Biospecimen Sourcing Platform: A Key Player in Advancing Health Research and Drug Discovery
Authors: Qusairy Zahraa , Rada Miran
Published: December 2023

The field of biobanking human biospecimens has evolved significantly, transitioning from the basic, often poorly documented collection of clinical leftovers kept privately to well-organized and extensively documented collections overseen by both commercial and non-profit platforms. The increasing demand for high-quality and clinically annotated biospecimens is propelled by unprecedented levels of health research activities. Meeting this growing demand presents both new opportunities and challenges, particularly in developing strategies to establish international biospecimen sourcing (IBS) platforms. These platforms aim to facilitate collaboration among biobanks to address future biospecimen needs. In this manuscript, we delve into the advantages and challenges of establishing IBS platforms to provide high-quality and cost-effective biospecimens to drive drug discovery research, ultimately leading to improved health and quality of life for everyone.
From Meso- to Microscopic Stochastic Modeling in Physico-Chemical Processes – the Paradigm of Chemical Reacting Systems
Authors: Pezzotti Chiara , Giona Massimiliano
Published: December 2023

The stochastic modelling of chemical physical processes is essentially based on a coarse-grained formulation of fluctuations, usually described by means of Wiener processes. By taking the paradigmatic example of chemical reaction kinetics, we propose a simple representation of microscopic stochastic dynamics grounded on the use of distributional derivatives of counting processes that account for elementary reactive events. This approach is consistent with the statistical analysis based on the Chemical Master Equation, and provides the formal setting for the existing algorithmic approaches (Gillespie algorithm). Some practical advantages of this formulation are addressed, and several other examples are discussed in connection with cluster formation, velocity fluctuations in liquid systems, and quantum transitions (radiative interactions) at the molecular level.

In recent years, the emergence of cancer drug resistance is one of the crucial tumor hallmarks which is supported by the level of genetic heterogeneity and complexities at cellular levels. Oxidative stress, immune evasion, metabolic reprogramming, overexpression of ABC transporters and stemness are among the several key contributing molecular and cellular response mechanisms. Topo-active drugs, e.g., doxorubicin and topotecan, are clinically active and are utilized extensively against a wide variety of human tumors and often results in the development of resistance and failure to therapy. Thus, there is an urgent need for an incremental and comprehensive understanding of mechanisms of cancer drug resistance specifically in the context of topo-active drugs. This review delves into the intricate mechanistic aspects of these intracellular and extracellular topo-active drug resistance mechanisms and explores use of potential combinatorial approaches by utilizing various topo-active drugs and inhibitors of pathways involved in drug resistance. We believe that this review will help guide basic scientists, pre-clinicians, clinicians, and policymakers toward holistic and interdisciplinary strategies that transcend resistance, renewing optimism in the ongoing battle against cancer.

The Tsukuba Challenge and the Nakanoshima Robot Challenge are both technical challenges in which mobile robots run autonomously in real outdoor environments. They have been held almost every year since 2007 and 2018, respectively, and many robots have participated in these public experiments. The autonomous navigation of a mobile robot in the real world, that is, not on test tracks but in environments normally used by everyday people, poses a great many challenges. The robots have to deal with environments that change with the time of day, the weather, the season, etc., and they have to deal with unexpected stationary obstacles as well as moving ones, including people, bicycles, etc. These days, demonstration tests of delivery robots are being conducted in many places, but there are still many problems that need to be solved. In this special issue, we have gathered papers detailing the insights gained from running mobile robots in the two outdoor experiments, the Tsukuba Challenge and the Nakanoshima Robot Challenge. To run a robot with a high success rate in a real environment, it is very important to devise the robot configuration, the sensor data processing, and the behavior control based on the knowledge gained from many experiences. We hope that sharing the successes and failures in the papers in this special issue will lead to further technological improvements in the future.
Robust Cooperative Transport System with Model Error Compensator Using Multiple Robots with Suction Cups
Authors: Matsunaga Nobutomo , Murata Kazuhi , Okajima Hiroshi
Published: December 2023

In cooperative transport systems, multiple robots work together to transport objects that are difficult to transport with a single robot. In recent years, multi-robot systems that cooperate to transport objects have been researched. However, during the transfer of objects, misalignment occurs between the ideal and actual grasp positions. In an automatic transport system, a grasping error can cause an error in the trajectory of the object, significantly reducing the transport efficiency. In this paper, a control system that allows robust cooperative transport control using a model error compensator is proposed for a leader–follower system in which the transported object is the virtual leader and the followers are ideally arranged. This system adds robustness to the operation of a conventional cooperative transport system by using the ideal formation of robots. The effectiveness of the proposed method was evaluated through cooperative transport experiments using two ideal formations for passing through a narrow entrance. The cooperative transport system could not pass through the narrow entrance using the conventional method; however, the system using the compensator passed through the narrow entrance smoothly.
Improved Visual Robot Place Recognition of Scan-Context Descriptors by Combining with CNN and SVM
Authors: Ye Minying , Tanaka Kanji
Published: December 2023

Visual place recognition from a 3D laser LiDAR is one of the most active research areas in robotics. Especially, learning and recognition of scene descriptors, such as scan context descriptors that map 3D point clouds to 2D point clouds, is one of the promising research directions. Although the scan-context descriptor has a sufficiently high recognition performance, it is still expensive image data and cannot be handled with low-capacity non-deep models. In this paper, we explore the task of compressing the scan context descriptor model while maintaining its recognition performance. To this end, the proposed approach slightly modifies the off-the-shelf classifier model of convolutional neural networks (CNN) from its basis, by replacing the SoftMax part with a support vector machine (SVM). Experiments with publicly available NCLT dataset validate the effectiveness of the proposed approach.
The National Raw Materials Policy in Poland as an instrument of implementation of the constitutional principle of ensuring the security of citizens (Article 5 of the Constitution of the Republic of Poland)
Authors: Ledwon Paulina
Published: December 2023

The author focuses on presenting the nature of the legal relationship between the principle of sustainable development established in the Constitution of the Republic of Poland and the policies adopted by the Council of Ministers: The National Raw Materials Policy, The Energy Policy of Poland, and the National Environmental Policy – the development strategy in the area of environment and water management. The author analyzes the concept of ensuring security as one of the constitutional obligations of the state authorities in the Polish Constitution and derives from it the concept of raw material security of the state, implemented by establishing The National Raw Materials Policy in 2022, which is understood as a long-term public policy conducted at the national level, to ensure that manufacturing enterprises have access to the raw materials necessary for their operations at a price enabling them to maintain their competitiveness, while taking care of the natural and social environment at every stage of the raw material cycle and the current and long-term economic security of the state.
