Authors: Albalawi Marzough A. , Hajri Amira K. , Jamoussi Bassem , Albalawi Omnia A.
Published: November 2023

A magnetite (CDC@Fe3O4) heterogeneous photocatalyst was synthesized via treated and modified cotton in two steps. The designed nanocomposites were characterized by FTIR, TGA, XRD, SEM, and VSM analyses. The Fenton-photocatalytic decomposition efficiency of the synthesized magnetic catalyst was evaluated under visible sunlight using Methyl Orange (MO) as a model organic pollutant. The impacts of several degradation parameters, including the light source, catalyst load, irradiation temperature, oxidant dose, and pH of the dye aqueous solution and its corresponding concentration on the Fenton photodegradation performance, were methodically investigated. (CDC@Fe3O4) heterogeneous catalyst showed a remarkable MO removal rate of 97.9% at 10 min under visible-light irradiation. (CDC@Fe3O4) nanomaterials were also used in a heterogeneous catalytic optimized protocol for a multicomponent reaction procedure to obtain nine tetra-substituted imidazole derivatives. The green protocol afforded imidazole derivatives in 30 min with good yields (91-97%) at room temperature and under ultrasound irradiation. Generally, a synthesized recyclable heterogeneous nano-catalyst is a good example and is suitable for wastewater treatment and organic synthesis.
Communitarianism, Complexity and Confusion in the Governance of Rural Sustainability Transitions in Advanced Industrial Economies: The Case of Scotland
Authors: Slee Bill
Published: November 2023

Rural areas of advanced industrial countries have frequently experienced a dualistic set of policies: one designed for the land-use sector, especially agriculture; and another dealing with rural development [1]. As problems of industrialised agriculture and forestry emerged, a more joined up approach to policy was advocated. Since the 1980s, at national and international level, new elements of rural policy have emerged to connect these two policy fields, including environmental payments, farm diversification grants, woodland creation within the farm sector and support for community-led local development. Rural land is also closely connected to the biodiversity and climate crises which have become important policy drivers. Policy towards community-led local development has moved further in Scotland than almost anywhere else as a result of policies for community-based land reform, community empowerment and community asset transfer. These communitarian approaches connect closely to collaborative landscape management as it addresses environmental challenges. As collaborative place-based and area-based approaches emerge as the guiding stars of the new rural development, this paper explores the challenges in the governance of sustainability transitions in moving from a sectoral rural policy hinging around support for land use to one based much more on communitarian values and place-based development.
The Role of Mineralogical Compositions on Wettability via Flotation Test and Surface Complexation Modelling (SCM)
Authors: Erzuah Samuel , Fjelde Ingebret , Omekeh Aruoture Voke
Published: November 2023

Minerals are the chief constituents of rocks and they have varied properties such as surface area, surface charge, site densities etc. Hence, numerous interactions are bound to occur in the reservoir during rock-fluids (i.e., rock, crude oil and brine) interactions. This study seeks to assess the role of mineralogical composition on the wettability of Sandstone Rocks (SR) and Mineral Mixture (MM) using both Surface Complexation Modelling (SCM) and flotation test. From the considered sandstone rocks, both the experimental results and its simulated counterpart revealed that, the SR were preferentially hydrophilic. For the MM, when the mass fraction of the hydrophobic mineral was increased, the affinity of the MM became slightly hydrophobic and vice-versa. For the dominant sandstone reservoir rock minerals with predominantly negatively charged surfaces, negligible oil adsorption took place due the interfacial repulsive forces at the oil-brine and mineral-brine interfaces. For the MM with low calcite content, the wetting preference was influenced by the mineral with prominent surface area. Our developed model portrayed that the main mechanism for oil adhesion onto sandstone minerals was divalent cations bridging. Nonetheless, adhesion of carboxylate (>COO-) onto the illite, montmorillonite and calcite sites also took place with the latter being more pronounced.

The Sarcoma Assessment Measure (SAM) was developed as a sarcoma-specific patient-reported outcome measure to be used in clinical practice. We have reported in detail how SAM has been developed in collaboration with patients and healthcare professionals. The aim of this paper is to report the preliminary validation of SAM. The 22-item SAM was administered alongside a validated quality of life questionnaire and measure of activities of daily living. Linear modelling was used to build a measure, which had predictive validity in comparison to more established outcome measures. Of the 762 patients who participated in the study, 44.1% identified as male, and participant age ranged from 13-82 years. Clinically, participants presented with a range of soft tissue (82.2%) and bone (21.8%) sarcomas. Our preliminary analysis indicates that SAM accounts for 35% of the Global quality of life scale and 18% of the TESS so psychometrically it overlaps with quality of life and activities of daily living, but also measures distinct concerns. This demonstrates that this measure picks up issues that are important to patients with sarcoma that are not reflected in other measures. We have established the preliminary validity of SAM and believe it has utility as a patient-reported outcome measure both as a research tool and for assessing the impact of symptoms and dysfunction related to sarcoma as part of clinical care. Further validation using a larger and more clinically diverse sample is now needed.

Published: November 2023

Shrubs are a significant component of urban vegetation residing in parks, but they experience various influences of biotic and abiotic agents, among which aphids play an important role. In this work, the effect of aphid colonization on three shrub species in urban environment was examined. Fourteen parameters have been analyzed, describing photosynthetic pigment content and gas exchange to carbon, nitrogen, and hydrogen partition. While no significant effect of colonization was found on photosynthetic pigment parameters, the effect was significant on gas exchange parameters. The strongest effect aphid colonization achieved on nitrogen partition and C/N ratio, parameters that could be suggested in further similar studies. All parameters were classified in two groups according to principal component analysis, suggesting correlation between nitrogen and carbon content, C/N ratio, measured gas exchange parameters and chlorophyll a content. The ratio between net photosynthesis and dark respiration (A/K) was in the second group, suggesting that this parameter provide additional information on the effect of aphid colonization, and deserve special attention in further studies. There were differences in reaction of examined shrub species, where the strongest reaction by gross primary productivity (GPP) achieved Hybiscus syriacus, and by nitrogen partition and C/N ratio Spirea trilobata and Cydonia japonica.

Published: November 2023

The paper presents research results on biocomposites made from a combination of extruded apple pomace (EAP) and potato starch (SP). The products were manufactured by hot pressing using a hydraulic press with a mold for producing samples. The prepared biocomposites were subjected to strength tests, surface wettability was determined and color analysis was carried out. Thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR) and cross section observed in Scanning electron microscope (SEM) were also performed. The obtained test results showed that the combination of apple pomace (EAP) and starch (SP) enabled the production of compact bicomposite materials. At the same time, it was found that each increase in the share of starch in the mixture for producing biocomposites increased the strength parameters of the obtained materials. With the highest share of starch in the mixture, 40%, and a raw material moisture content of 14%, the material had the best strength parameters and was even characterized by hydrophobic properties. It was also found that materials with a high content of starch are characterized by increased temperature resistance. Analysis of SEM microscopic photos showed well-glued particles of apple pomace, pectin, gelatinized starch and a smooth external structure of the samples. Research and analyzes have shown that apple pomace reinforced only with the addition of starch can be a promising raw material for the production of simple, biodegradable biocomposite materials.
Improved DIRECT-type Algorithm Based on a New Approach for Identification of Potentially Optimal Hyper-Rectangles
Authors: Belkacem Naziheddine , Chiter Lakhdar , Louaked Mohammed
Published: November 2023

This paper introduces new improvements to the modified version of the BIRECT (BI secting RECTangles) algorithm referred to as BIRECTv. We explore various approaches, by first including a grouping strategy for hyper-rectangles having almost the same sizes by categorizing them into different classes. Therefore constraining them not to exceed a certain pre-defined threshold (a small positive value to define the tolerance level). This approach allows for more efficient computation and can be particularly useful when dealing with a large number of hyper-rectangles with varying sizes. To avoid over-sampling, and preventing redundant or excessive sampling, at some shared vertices in descendant subregions, a particular vertex database is used to limit the number of samples taken within each subregion to two. The experimental investigation shows that these improvements have a positive impact on the performance of the BIRECTv(imp.) algorithm and the proposal is a promising global optimization algorithm compared to the original BIRECTv algorithm and its variants. Additionally, the BIRECTv(imp.) algorithm showed particular efficacy in solving high-dimensional problems.

Published: November 2023

Wound healing in the pediatric population is known to be a challenge and poorly studied. Split-thickness skin grafts, full-thickness skin grafts and flaps overlap their applications with the growing field of cellular and tissue-based therapies. However, their role in pediatric reconstruction has yet to be defined. The Kerecis® Omega3 wound patch, derived from decellularized codfish skin, has garnered attention due to its preserved microscopic architecture resembling the human extracellular matrix. This acellular dermal matrix acts as a scaffold, fostering dermal cell and capillary adhesion while harnessing omega-3 polyunsaturated fatty acids for granulation acceleration and antimicrobial effects. This study presents a comprehensive review and surgical protocol for utilizing Kerecis® fish skin in pediatric wound care. The research embraces a case series involving five patients with diverse wound locations. The Kerecis® Omega3 wound patch underwent meticulous application and careful monitoring. The results highlight an average time of 48.6 days for complete epithelialization, yielding favorable outcomes with no hypertrophic scarring and mild retraction. Notably, this innovative approach may eliminate donor site morbidity and improve pain control, promising a novel avenue for pediatric wound management.

Published: November 2023

The use of ARPIs has led to an increase in the proportion of AR-null prostate cancer, including NEPC and DNPC, but the mechanism underlying this lineage transition has not been elucidated. We found that ID2 expression was increased in AR-null prostate cancer. In vitro and in vivo studies confirmed that ID2 promotes PCa malignancy and can confer resistance to enzalutamide in PCa cells. We generated a ID2 UP50 signature, which is capable to determine resistance to enzalutamide and also valuable for predicting patient prognosis. Functional experiments showed that ID2 could activate the stemness-associated JAK/STAT and FGFR signaling while inhibiting the AR signaling pathway. Our study indicates that ID2 promotes the acquisition of a stem-like phenotype in adenocarcinoma cells, leading to resistance to ADT and next-generation ARPIs in prostate cancer.
Digital Literacy in People With Disabilities: An Overview and Narrative Review
Authors: VENKATESAN SRINIVASAN
Published: November 2023

Digital literacy is the ability to use digital technologies to find, evaluate, create, and communicate information. People with disabilities benefit from having these skills because they allow them to access various opportunities in the digital world. To ensure that they can fully participate in the digital realm, digital literacy efforts should prioritize inclusive design principles. People with disabilities often rely on assistive technologies such as screen readers, alternative input devices, voice recognition software, or specialized hardware to navigate digital platforms. Digital literacy programs should not only focus on consuming content but also on creating and sharing it through documents, multimedia, and online platforms. Peer support and collaboration are important for enhancing their learning experience. Additionally, digital literacy programs address cybersecurity or online safety considerations specific to such people and provide them training and support for using assistive technologies effectively while educating them about potential risks, privacy settings, and safe online practices. This narrative review highights the meaning and levels of digital literacy, digital divide, history, before expanding on the quantative metrics in the available research on the theme of people with disabilities. Retrieved data from freely accessible internet search engines revealed 196 publications, including books, chapters in books, original research articles, proceedings of seminars, and reviews, which were classified into harvest plots to be analyzed by their format, timelines, topics, or themes, respectively. While results indicate an upward curve in the quantity of publications, especially in the post-millennium era, the topics addressed are unevenly distributed, leaving scope for the future to focus empirical and evidence based research on themes related to measurement as well as training on digital literacies for both teachers and students with disabilities. By promoting digital literacy in people with disabilities, we can bridge the digital divide and empower them to participate fully in today's increasingly digital society.

Published: November 2023

2,4-dichlorophenoxyacetic acid (2,4-D) is a globally used herbicide and is frequently found in water samples. This fact has prompted studies on its effects in non-target organisms, revealing significant alterations on liver structure and function. In this review, we evaluated the literature on the hepatotoxicity of 2,4-D, focusing on morphological damages, biomarkers of toxicity and affected liver functions. Searches were conducted on PubMed, Web of Science and Scopus and 83 articles were selected after curation. Among the studies, 72% used in vivo models and 30% used in vitro models. Additionally, 48% used the active ingredient, and 35% used commercial formu-lations in exposure experiments. The most affected biomarkers were related to a decrease in an-tioxidant capacity, including alterations in the activities of catalase and superoxide dismutase, and in the levels of malondialdehyde. Changes in energy metabolism, lipids, liver function, and xenobiotic metabolism were also identified. Furthermore, we found studies about the effects of 2,4-D in mixtures with other pesticides, as well as hepatoprotection trials. The reviewed data in-dicate that the reduction in antioxidant capacity and oxidative stress play an important role in 2,4-D-induced hepatotoxicity. However, the mechanism of action of the herbicide is still not ful-ly understood and further research in this area is needed.

Published: November 2023

In small animal models of severe acute respiratory syndrome coronaviruses (SARS-CoV and SARS-CoV-2) infection, ferrets (Mustela putorius furo) have been used to investigate the pathogenesis. Podoplanin (PDPN) is an essential marker in lung type I alveolar epithelial cells, kidney podocytes, and lymphatic endothelial cells. Monoclonal antibodies (mAbs) against ferret PDPN (ferPDPN) are useful for the pathological analyses of those tissues. We previously established an anti-ferPDPN mAb, PMab-292 using the Cell-Based Immunization and Screening (CBIS) method. In this study, we determined the critical epitope of PMab-292 using flow cytometry. The N-terminal ferPDPN deletion mutants analysis revealed that the Val34 is located at the N-terminus of the PMab-292 epitope. Furthermore, the PA tag-substituted analysis (PA scanning) showed that Asp39 is located at the C-terminus of PMab-292 epitope. The epitope sequence (34-VRPEDD-39) also exists between Val26 and Asp31 of ferPDPN, indicating that PMab-292recognizes the tandem repeat of the VRPEDD sequence of ferPDPN.

Authors: Sutarmi Nanik
Published: November 2023

Tujuan dilakukannya penelitian ini adalah untuk mengetahui bagaimana Pengaturan Pemerintah dalam hal ini melaksanakan Pengadaan Tanah Untuk Kepentingan Umum sesuai dengan Undang-Undang no 2 Tahun 2012 dan bagaimana Hak dari masyarakat yang Tanahnya terkena Pengadaan Tanah Untuk Kepentingan Umum. Penelitian ini menggunakan metode penelitian yuridis normatif dan dapat disimpulkan: 1. Undang-undang No. 2 Tahun 2012 memang memiliki kekuatan Hukum yang mengikat. Namun secara pelaksanaannya masih terdapat kelemahan-kelemahan, antara lain: terlalu luasnya arti Kepentingan Umum, bentuk dan dasar perhitungan ganti kerugian kepada pemilik hak atas tanah, dan mekanisme Pengadaan Tanah yang dilakukan oleh Pemerintah. 2. Regulasi yang mengatur Pengadaan Tanah untuk Kepentingan Umum tidak menjamin pemegang Hak Atas Tanah memperoleh kehidupan yang lebih baik dibandingkan sebelumnya. Hal itu disebabkan karena dasar perhitungan ganti rugi hanya memperhitungkan kerugian yang bersifat fisik yaitu: tanah, bangunan, dan tanaman yang berada diatasnya. Kerugian non fisik yang terkait dengan sosiologis, yang dialami pemilik hak atas tanah tidak diperhitungkan dan diatur dalam peraturan perundang-undangan.

Character education is an effort to instill character values that include religious, nationalist, integrity, independent and mutual cooperation attitudes. Character education has the aim of forming a mindset, attitude and behavior of students so that they have a noble character that is related to themselves, society and God. In the current era which is already in the era of globalization, foreign cultures can easily influence the characters of students. The entry of foreign culture can be through the media that becomes a bridge for students to see the outside world. The influence of these foreign cultures causes negative impacts such as having free sex, brawls and things that do not reflect the character of the Indonesian nation. Through historical heritage we can find out how the character of our own nation, for example the Heroes Monument in Surabaya, is not only a symbol of the city of Surabaya but also as a symbol that the Indonesian people, especially the citizens of Surabaya, are people who do not give up and have high integrity. from the Dutch colonial era to the war of Independence. This study aims to describe the urgency of Tugu Pahlawan in strengthening character education in the era of global culture. In this study, the researcher used the literature study method by collecting several articles and other written sources that matched the themes discussed. The results of this study show Tugu Pahlawan as a reminder that life today is the result of the sacrifices of the fighters and as a symbol that the character of the Surabaya people is a person who does not give up.

Published: November 2023

The character of students in the current era of globalization does not reflect to be a successor of the nation. This can be seen from the large amount of violence, cyberbullying, the lack of humanism among students, the culture of plagiarism, and what is worse is that there is a sense of pride in foreign cultures. These cases are of course very inversely proportional to the noble values of Pancasila which have been instilled by every higher education institution in Indonesia. To overcome this, of course, higher education institutions must continue to develop and develop character education which aims to ensure a dignified future of the nation and has a character that is in accordance with the values of Pancasila. Therefore, higher education institutions play an important role in character education in every activity. One of the efforts that must be tried by higher education institutions is to utilize local cultural products as a medium for character education learning. The existence of positive values in indigenous cultural products such as the Dulmuluk theater that developed in Palembang society will certainly elevate and develop the character of students into a quality generation, and capable of mastering science, technology and art.

At this time, human resources who have creative characters are needed by the nation to overcome the country problems that grow amidst the uncertainty of world conditions. University are educational institutions that are expected to be able to produce these resources. In the learning process at university, students are trained to have a number of characters, which one of them is creative. However the process of character education that make students become creative is not enough, if they only rely on the learning process with lecturers, they need other containers outside of this, that are able to add experience and expand students thinking. The existence of the Student Activity Unit in University can be one of the other container because Student Activity Unit provides students with the opportunity to get experience interaction with the environment so that they can encourage creative characters to grow and develop.

In this paper, the main existing problems of monitoring power system objects are outlined, because the regular inspection of electrical power system devices and apparatus allows to evaluate a technical condition, to detect presence of defects and to prevent emergency situations. The paper carries out an analysis of promising solutions in the process of inspecting the technical condition of objects or emergency sections of power grids using drones. The article considers the definition, advantages, and disadvantages of unmanned aerial vehicles, provides a list of tasks that they can perform, considering their own design and technical parameters. The main components of the structural control scheme of an unmanned aerial vehicle and the possibilities of expanding, improving, and eliminating existing shortcomings are described. Existing technologies for automatic control, detection and tracking of electric overhead lines and devices by an unmanned aerial vehicle are described. The basic principle of operation of thermal field and electromagnetic field sensors is analyzed as the most promising to date in determining the malfunction of devices. Firstly, in the case of a fault, objects can produce thermal energy and partial discharges, which the sensor is able to measure at a distance and convert into temperature. Secondly, the electromagnetic field around the objects changes in the event of the same damage, and measuring the value of this parameter with a special sensor allows to detect damage. The issues of ensuring the protection of the communication channel between the ground unit and the drone from intruders and information security of data exchange are also considered. The possibilities of developing existing technologies to improve the process of monitoring the general technical condition of the electrical network, searching for damaged electrical sections and devices, automating the control process, and reducing the cost of the device are analyzed.
A method for recognising the type of fault in oil-filled equipment based on the gas percentage

One of the main tasks of the electricity sector is to ensure a reliable supply of electricity. Transformers play a key role in this, as their operation determines the reliability of the energy infrastructure. One of the factors that is common to all countries and affects the reliability of equipment is the ageing of this equipment as a result of various processes, including faults developing inside this equipment. One of the most effective methods of diagnosing high-voltage oil-filled equipment is the dissolved gas analysis, which allows for the recognition of various types of faults. Using different diagnostic criteria (gas ratios, percentage of gases, and gas to gas ratios with maximum content), different types of faults can be identified. One of the most commonly used diagnostic criteria is the percentage of gases. However, the reliability of fault detection by different methods for the same data varies considerably. The greatest difficulty arises when recognising combined faults. Therefore, the issue of developing a method for recognising the type of fault based on the results of the analysis of gases dissolved in oil using the percentage of gases as a diagnostic criterion is relevant and of practical importance. The article proposes an analytical method for recognising the type of fault in high-voltage oil-filled equipment based on the percentage of five gases in the oil. The article considers the recognition of different types of faults, for which the gases with the maximum content are hydrogen, methane, ethane, ethylene and acetylene. The values of the percentage of gases characteristic of a particular type of fault are given in the form of tables, which show the ranges (minimum and maximum values) and average values of the percentage of gases. As a result of the analysis, for the first time, the ranges of percentage gas content values for 50 groups of faults of various types, including combined faults, were established. This makes it possible to significantly increase the number of faults that can be recognised using the percentage of gases as a diagnostic criterion. In the process of developing the method, it was found that in a number of cases, it is not enough to use only the percentage of gases, but there is an objective need to use both the values of gas ratios and fault nomograms to determine the type of fault.

The existing schemes of command apparatus are presented. Their analysis is carried out and the shortcomings are indicated. The scheme of afundamentally new command apparatus is given, which can significantly reduce the number of its elements. The synthesis of the pneumatic controlsystem of the foundry machine was carried out on the basis of the design approach proposed by M. Cherkashenko, which as a result led to a reductionin the devices by 3.5 times. A graph of operations of the pneumatic control system of the molding machine is constructed. A matrix ofcorrespondences is obtained, which determines the correspondence between the signals that cause transitions and the complete input sets acting in thetransitions. Analysis of the matrix of correspondences made it possible to identify and eliminate contradictory transitions. On the basis of theelongations, a system of equations describing the scheme of the control system is synthesized. Further, minimization is performed due to factorizationand decomposition of equations, and obtaining equations in their final form. A diagram is presented pneumatic control system of the molding machine,consisting of a command apparatus containing three cells, five cylinders, two vibrators, six limit switches, a time relay and other devices. The circuitsimultaneously uses the functional and logical capabilities of limit switches, the possibility of implementing the functions of three variables bydistributors. Thus, the use of the proposed command apparatus, in contrast to the existing schemes of command apparatus, can significantly reduce thenumber of distributors in the synthesis of the command apparatus itself and significantly reduce the number of elements when using the chosenapproach to the design of circuits of pneumohydraulic control systems.

The reliability of hydropneumodrives largely determines the safety of machine tools, metal cutting equipment, the movement of transport vehicles, and the flight of modern passenger aircraft, and their failures can in some cases lead to accidents. The design stage is crucial in ensuring reliability. The main tasks of reliability research and calculation at this stage can be divided into three groups. First, it is a justification of reliability requirements for the main elements of the hydraulic pneumatic actuator (the task of reliability norming). This task is solved at an early stage of design and involves the preliminary development of the unit structure and justification of design principles. Secondly, it is to ensure the reliability of the elements and the unit as a whole. This group of tasks includes research and quantitative assessment of the efficiency of possible ways to ensure reliability; selection of basic design characteristics, statistical reserves of durability and longevity, stability reserves and other indicators; comparative analysis of options and selection of optimal designs. Thirdly, these are control calculations of the unit's reliability according to the design documentation. Algorithms for the distribution of normalised reliability indices at the design stage for hydropneumodrives implemented by the standard positional structure method and the minimisation method are obtained. Algorithms allow already at the early stages of hydropneumodrive design to normalise reliability indices, which makes it possible to obtain optimal solutions of reliability issues at the subsequent stages of development of the drive life cycle. The methods of calculation and determination of design relations for finding quantitative characteristics of failure-free indices of designed hydropneumodrives, implemented by the method of standard positional structure and the method of minimisation, are selected, which allows designing highly reliable hydropneumodrives for new metal cutting equipment. Evaluation of reliability indicators of hydropneumodrives at the stage of preliminary design allows to make a rational choice of structural scheme and parameters, to select appropriate materials and elements of scheme realisations.
