Railway crossings - some experiences from the practice of reconstructed crossings
Authors: Kralj Stjepan , Iličić Frane , Kralj Mario
Published: October 2024

Level crossings (Rail-road crossings and pedestrian crossings) are places where rail and road traffic meet directly. As such, they represent points of high risk where accidents often occur with serious consequences in the form of human casualties and material damage. Rail-road crossings and pedestrian crossings over the railway at level are not a problem and the subject of solving only the section of the railway, but the very safety of traffic at these points depends significantly on the construction-traffic solution of the road in the immediate vicinity of the railway crossing. A big problem is the fact that there are a large number of railway-road crossings which, according to the regulations, would have to be built out of grade. However, due to the high costs of such solution, transport infrastructure managers often resort to other ways of securing railway-road crossings. The paper presents some examples of good and bad practice in the location, construction and level of security of railway-road and pedestrian crossings on the reconstructed railway network in Croatia. A comparison was made of some safety-technical solutions and technical means at our railway and road crossings of the European Union, as well as a comparison of the effectiveness of certain measures with regard to the behavior of road users.

Since November 2022, acceptance of international cruises, stopped due to the impact of COVID-19, has resumed in Japan. As a result, in 2023, the number of international cruise calls in Japan showed signs of recovery and initiatives for the revival of cruising are being proceeding. In 2023, cruise ships also called at Kanazawa Port 47 times, recovering the number of port calls to nearly the number before COVID-19. As a result, many foreign and Japanese tourists visited Kanazawa city. In cruise tourism, passengers visit each port of call all together, so it is expected that each call will make a significant contribution to stimulating local tourism and economic activity. Therefore, the amount spent by cruise ship passengers on sightseeing at ports of call is an important source of income for the finances of local governments. The aim of this study is to clarify the factors that influence the amount of consumption with the aim of achieving sustainable development of cruise tourism in Kanazawa City. The author's research group conducted questionnaire surveys on tourism in Kanazawa City targeting cruise ship passengers who called at Kanazawa Port. Moreover, the target cruise ship was the MSC Bellissima, a large cruise ship with a capacity of 5568 passengers. From the results of the questionnaire, the influence on the amount of money spent by cruise ship passengers sightseeing in Kanazawa was clarified, and important knowledge was obtained for the future development of cruise tourism in Kanazawa City.

Published: October 2024

Microalgae are a promising component to enhance human nutrition, but to date only a few species have been authorized to be used in human nutrition. In this study, the in vitro toxicity of eight novel microalgae strains (Botryococcus braunii, Chlorococcum novae-angliae, Microchloropsis salina, Myrmecia bisecta, Stichococcus sp. Tetraselmis suecica, Tetradesmus obliquus and Spongiochloris minor) selected for their potential for human nutrition was investigated. N-hexane, acetone, ethanol and aqueous extracts of the lyophilized biomass were tested in the CHO-k1 and HEP G2 cell lines at concentrations of up to 1.81 mg ml-1 extracted biomass per well. None of the tested microalgae extracts reached values defined as a significant cytotoxic effect (IC50 < 0.02 mg ml-1). The highest cytotoxic effects were measured for Stichococcus sp. in both cell lines with IC50 values of 0.17 mg ml-1 for the acetone extract in CHO-k1 cell culture and 0.18 mg ml-1 for the acetone extract in HEP G2 cell culture. Most cytotoxic effects occurred with the acetone and ethanol extracts, while the water and n-hexane extracts showed almost no measurable cytotoxic effects. Only Tetraselmis suecica showed no cytotoxic effect under the chosen conditions in both tested cell lines, marking this microalgae as particularly interesting for further investigations into its use in human nutrition.

The article presents the results of the material and varietal assessment of the balance reserves of limestone of a large deposit. On the basis of electrometric measurements of the massif and modeling of the collapse of the exploded rock mass, using the example of the Kostanok site of the Chanvin limestone deposit (Perm Krai), a 2-stage method for studying complex-structured arrays of mineral raw materials is proposed. The results of large-scale electrometric surveys and local measurements of explosive blocks by the method of resistances in combination with vertical electro-sounding (VEZ) are presented. Quantitative maps of the isolines of the contaminant (clays) of the mined sections of the limestone massif are presented, which are the initial data in the models of the ruins of the exploded rock mass. The main parameters of the geometric interpretation of the composition of the exploded ore mass are established. To quantify the volumes of conditioned and dilute limestone in the collapse of the exploded ore mass, the differentiation of elastic-plastic properties of limestone layers of different grade composition depending on the angles of inclination of the working ledges was revealed. The typicality of the structure of the limestone-clay zones as forms of origin of clogging substances of facies-tectonic genesis has been established. The parameters and main provisions of the methodology for assessing losses and dilution of minerals in complex geological and technical conditions of mining operations are determined. Using the example of the Kostanok limestone site, an algorithm has been developed for obtaining information about the structure of the structure of the processed massif to increase the efficiency of mining operations. The results obtained confirm the relevance of the oxide-metric interpretation of electrometric measurement data for assessing the degree of loss and clogging of the extracted ore mass during the development of complex-structured arrays.

PROMISING SORBENTS FOR THE EXTRACTION OF NICKEL AND COBALT IN THE HYDROMETALLURGICAL PROCESSING OF NICKEL ORES
Authors:   ederal State Budgetary Institution of Science Research Geotechnological Center of the Far Eastern Branch of the Russian Academy of Sciences, POPOV Grigory Vasilievich
Published: October 2024

The paper provides a critical analysis of the sources, a generalization of the factual and theoretical material on the properties, the use of natural and synthetic sorbents for the extraction of nickel and cobalt from productive solutions after the leaching of nickel ores. Comparison of promising sorbents in terms of efficiency of their use with sorbents used in industry has been carried out. Sorption processes using natural substances or synthetic resins contribute to the selective extraction of nickel and cobalt from aqueous solutions. Zeolites modified with various functional groups are very promising materials for selective recovery. The ability to selectively extract metal cations and the possibility of regeneration makes ion-exchange polymer resins one of the leading sorbents in the modern world. The polymer resin sorption process avoids wastage of reagents, costly filtration, and poor selectivity for nickel and cobalt over other metal ions associated with solvent extraction processes. A comparison of the values of the sorption capacities of natural sorbents shows the promise of using silicate minerals - montmorillonite and palygorskite in industry, as well as the development of technological processes using them. Analysis of the recovery rates of synthetic polymer resins proves the frequent use of Amberlite, Dowex and Ionac in the industry. However, Dowex M4195 has the highest nickel selectivity due to the presence of a bis-picolylamine functional group, unlike other resins with an iminodiacetate group. In addition, the disadvantage of foreign-made chelate resins is their high cost, which cannot be said about the cation exchanger grade KU 2-8 of a Russian manufacturer.

Introduction: Eosinophilic esophagitis is a chronic disease characterized by the accumulation of eosinophils in the esophageal wall, causing inflammation and damage to the esophageal mucosa, which can affect swallowing ability. Despite being an idiopathic disease, it is believed that several factors may trigger the overproduction of eosinophils. Diagnosis is made through endoscopy, where the esophageal mucosa is examined, and a biopsy is taken to detect the presence of eosinophils in the esophageal tissue. Treatment is multidisciplinary, including dietary modifications (such as restricting foods that trigger the inflammatory response) and pharmacological therapy. In severe cases, esophageal dilations may also be considered to relieve esophageal narrowing.Methods: Data were collected from articles indexed in Scopus, PubMed, Scielo, and Elsevier, considering bibliographies in English and Spanish from 2017 to 2024. For this investigation, 72 articles were used as references.Results: After analyzing the selected articles, important aspects of eosinophilic esophagitis were identified. Various studies concluded that the prevalence of this pathology has increased in recent years, with a higher incidence of cases in Western countries, suggesting a possible link to environmental and dietary factors. This disease affects both children and adults, with a higher frequency in men.Conclusions: The analysis of the bibliographic sources used in the research reveals that, despite being discovered just over 30 years ago, eosinophilic esophagitis remains an idiopathic disease, affecting a diverse population regardless of age. Studies show that the exact reasons why certain individuals are more susceptible than others have not been determined, suggesting a complex interaction between genetic, immunological, and environmental factors.

Published: October 2024

Abiotic stresses, particularly salinity, severely hinder crop productivity by disrupting physiological processes and reducing yields. Pea (Pisum sativum L.), a vital crop, is highly sensitive to salinity, making it crucial to explore strategies that enhance its tolerance to such stresses.  This study investigates the effects of Ascorbic Acid (AsA), 5-Aminolevulinic Acid (ALA), and Nano-Selenium (N-Se) on the anatomical characteristics of pea  plants subjected to severe salinity stress (120 mM NaCl). Transverse sections of the fourth internode and leaf blade were analyzed, focusing on stem and leaf structure. The results showed that foliar application of AsA (100 ppm) significantly improved anatomical traits, such as stem diameter, cortex thickness, and vascular bundle dimensions, compared to the control and other treatments. ALA (50 ppm) also improved anatomical features, albeit to a lesser extent, while N-Se (20 ppm) exhibited the lowest enhancement. Leaf tissue analysis revealed that AsA improved leaflet structure, increasing epidermis thickness and vascular bundle dimensions under salinity stress. The application of AsA, ALA, and N-Se mitigated the negative effects of salinity, likely due to their roles in enhancing stress tolerance, reducing oxidative damage, and improving nutrient uptake. This study highlights the potential of these bio-stimulants to improve the anatomical resilience of pea plants under salinity stress, contributing to better crop performance in saline environments.

يعتبر إصلاح أنظمة التقاعد إشكالية على المستوى العالمي. ولا يمكن لأي نظام للتقاعد أن يضمن ديمومته واستمراريته دون أن يكون مرتكزا على أسس صلبة ومنسجمة وثابتة في كل أبعاده: التقنية والقانونية والاجتماعية والسياسية والاقتصادية. أما بالنسبة لتجربة المغرب، فإن إصلاح منظومة التقاعد إشكال نوقش لسنوات عديدة، وخلق مجموعة من التراكمات. فكرونولوجيا الأحداث تبين أن التفكير في إصلاح أنظمة التقاعد ليس وليد اليوم بل مر عبر مجموعة من المراحل. وهذا الإصلاح حددت قواعده في ثلاثية خطيرة هي: الزيادة في سن التقاعد، والرفع من نسبة المساهمات وكذا طريقة الاحتساب. ورفع سن التقاعد، حسب رأي اللجنة التقنية المكلفة بإصلاح التقاعد، هو حل لا محيد عنه في إصلاح منظومة التقاعد، لأنه يحقق مجموعة من الإيجابيات، لكن لا يجب النظر إليه على أنه العصا السحرية التي ستحل الأزمة نظرا لمجموعة من الاعتبارات. كما أنه لا بد من تدارس بدائل أخرى تكون أكثر فاعلية وجدوى.
 
Reform pension systems is a problematic at the global level. No retirement system can guarantee its sustainability without being based on solid, harmonious and consistent foundations in all its dimensions: technical, legal, social, political and economic. As for Morocco's experience, pension reform was a problem that had been discussed for many years and created a range of accumulations. Chronology of events shows that thinking about reforming pension schemes is not born today but has passed through a range of stages. This reform defined its rules in a dangerous triple: an increase in retirement age, an increase in the proportion of contributions and the method of calculation.
Raising the retirement age, according to the Technical Committee on Pension Reform, is an inevitable solution in pension reform, as it achieves a range of positives, but it must not be seen as the magic wand that will resolve the crisis owing to a range of considerations. Other alternatives that are more effective and feasible must also be considered.
الجيوبوليتيك والسلوك السياسي للدولة: دراسة لأثر الجيوبوليتيك في رسم ملامح النظام التعليمي
Authors: بونخلة أميمة
Published: October 2024

تهدف هذه الدراسة إلى إبراز التأثيرات المتنوعة للجيوبوليتيك على قطاع التعليم، من خلال تحليل حالتين كل واحدة منهما تختلف عن الأخرى من ناحية الموقع والإيديولوجيا، وهما النموذجان الفرنسي والإيراني، وتقديم رؤية شاملة لكيفية تفاعل هذه التأثيرات مع التغيرات العالمية. سنستعرض كيفية تأثير النزاعات الجغرافية والسياسية على صياغة المناهج الدراسية واختيار الأفكار المراد تمريرها بعناية، وكيف تشكل التحالفات السياسية والاقتصادية الدولية سياسات التعليم الوطنية. كما سنتناول دور التعليم في تعزيز الفهم الجيوبوليتيكي، وأهمية التعليم كأداة لتعزيز الاستقرار والسلام العالمي. تعتمد هذه الدراسة المنهج التحليلي المقارن، وهو منهج يقوم على تحليل الظواهر من خلال الوقوف على نقاط التمايز والتشابه بينها. يمكننا أن نستخلص أن كلا النموذجين الفرنسي والإيراني، يستخدم التعليم كأداة قوية لتحقيق أهدافه الجيوبوليتيكية والإيديولوجية. في فرنسا، يتم ترويج السلم والتعايش على السطح، ولكن مع الحفاظ على شعور بالتفوق الثقافي الغربي. في إيران، يتم ترويج الولاء الديني الشيعي والتفوق العرقي الفارسي، مع توجيه الطلاب نحو العداء للعرب السنة وتعزيز التوسع الإقليمي. كلا النموذجين يعكسان تأثير التاريخ والثقافة والسياسة في تشكيل المناهج التعليمية وتوجيه الأجيال الجديدة نحو تبني قيم ومعتقدات تخدم الأهداف الاستراتيجية للدولة. هذا الأثر الذي تتركه السياسة الجيوبوليتيكية على التعليم، يتطلب خاصة بالنسبة للدول التي تخضع لنفوذ القوى الكبرى أن تعمل على حماية هويتها الثقافية.
 
This study aims to highlight the diverse impacts of geopolitics on the education sector by analyzing two distinct cases— the French and Iranian models— each differing in location and ideology. It seeks to provide a comprehensive view of how these influences interact with global changes. We will explore how geographical and political conflicts shape curriculum development and the deliberate selection of ideas, and how international political and economic alliances shape national education policies. Additionally, we will discuss the role of education in promoting geopolitical understanding and its importance as a tool for enhancing global stability and peace. This study employs the comparative analytical method, which involves analyzing phenomena by identifying points of differentiation and similarity. We can conclude that both the French and Iranian models use education as a powerful tool to achieve their geopolitical and ideological objectives. In France, peace and coexistence are promoted on the surface, but with an underlying sense of Western cultural superiority. In Iran, Shiite religious loyalty and Persian ethnic superiority are promoted, directing students towards hostility against Sunni Arabs and advocating for regional expansion. Both models reflect the influence of history, culture, and politics in shaping educational curricula and guiding new generations to adopt values and beliefs that serve the strategic goals of the state. This impact of geopolitical policy on education particularly requires countries under the influence of major powers to work on protecting their cultural identity.

This research aims to shed light on an explanation of the jurisprudence of operations and its judicial applications, by the late Moroccan Maliki jurists, which is the explanation of " Tuhfat akyās al-nās in Fez operations” by Al-mahdi Al-wazzani in explaining jurisprudential systems by Sheikh Abi Zaid Abd al-Rahman bin Abd al-Qadir al-Fassi. This explanation deals with the jurisprudence of operations, or what is known as mājara bihi al 3amal "what has been done", which is a Maliki jurisprudential heritage that appeared in the Islamic West, influenced by the work of the people of Medina in the East. This study dealt with introducing the explanation of Tuhfat al-akyās, defining the Fez operations, and explaining the jurisprudential methodology with which the jurist Al-wazzani dealt with his explanation of this system, and we chose from some examples, even if it contradicted doctrine. The findings of this study produced the importance of jurisprudential explanations, especially in operational jurisprudence, and the necessity of paying attention to jurisprudential explanations, especially the explanations of recent scholars, due to their connection to contemporary judicial applications.
