Published: April 2024

Orchids are a diverse and widespread family of flowering plants, with over 25,000 known species and more than 100,000 hybrids and cultivars. Orchids are characterised by their often showy and highly specialised flowers and have unique and intricate floral. Orchids are known to be highly dependent on their mycorrhizal fungi for nutrient uptake, especially during the early stages of their development. Orchid seeds lack the endosperm present in most other seeds, which means they cannot germinate without a source of nutrition. The relationship between orchids and mycorrhiza is known as orchid mycorrhizae or orchid mycorrhiza. In orchid mycorrhiza, the orchid plant forms a mutualistic relationship with certain species of fungi that are able to penetrate the orchid’s roots and colonise its tissues to provides the orchid with essential nutrients. Orchid mycorrhizal fungi are often highly specific, meaning that they can only form partnerships with certain orchid species, and vice versa. The importance of mycorrhizal fungi in the orchid life cycle is crucial from both evolutionary and ecological standpoints. Therefore, it is essential to acquire a thorough comprehension of this relationship and develop methodologies for isolating, identifying, and preserving significant fungal strains that are associated with different orchid species. In recent years, there has been a considerable increase in research concentration on mycorrhizal interactions in orchids. However, certain inquiries remain unresolved pertaining to the fungal communities associated with orchids as well as the divergences notices across different species and geographical locales. The present paper provides a through, and extensive analysis of the fungal life associated with orchids. This article presents a succinct overview of the molecular techniques utilised by researchers globally to isolate and identify peloton-forming fungi in both temperate terrestrial and tropical orchids. The review begins by proving a concise introduction to the background material regarding the wide range of fungal species that are linked with orchids. It then proceeds to explores the topic of orchid mycorrhizal fungi (OMF) and orchid non-mycorrhizal fungi (ONF). The subsequent analysis explores the crucial function that orchid mycorrhizal fungi play in the processes of seed germination and development. Moreover, the study elaborates on the methodologies utilised for isolating fungi, extracting fungal DNA, selecting primers, amplifying DNA and subsequent analysis sequence data. This article considers several molecular identification approaches that are used in studying orchid endophytic mycorrhizal. Using molecular approaches, orchid mycorrhizal can be further explored and identified.

Energy from pavements can be harvested in multiple ways to produce clean energy. One of the techniques is electromagnetic energy harvesting, in which mechanical energy from vehicles is captured in the form of input displacement to produce electricity. In this study, a rack-and-pinion electromagnetic energy harvester proposed in the literature as a speed bump is optimized for highway-speed vehicles. A displacement transfer plate is also proposed, with a minimum depth of embedment in the pavement to carry input displacements from passing vehicles and excite the energy harvester. The energy harvester was designed, and kinematic modeling was carried out to establish power–output relations as a function of rack velocity. Sensitivity analysis of various parameters indicated that, for high-speed applications where rack velocities are relatively high, small input excitations could be harnessed to achieve the rated revolutions per minute (RPM) of the generator. A set of laboratory tests was conducted to validate the kinematic model, and a good correlation was observed between measured and predicted voltages. Dynamic modeling of the plate was done for both recovery and compression to obtain the plate and rack velocities. Using Monte Carlo simulation, the plate was designed for a class-9 truck with wide-base tires moving at 128 km/h. Design and layout of the energy harvester with a displacement transfer plate was proposed for field validation. The energy harvester with the displacement plate could be integrated with transverse rumble strips in construction zones and near diversions. Hence, it could be used as a standalone system to power roadside applications such as safety signs, road lights, speed cameras, and vehicle-to-infrastructure (V2I) systems.

Published: April 2024

The important role of the transport and logistics system and its infrastructure in realizing the export potential of Ukraine’s regions in the context of a protracted war and post-war recovery requires well-considered public policy measures to support them and further develop them. The measures should aim to increase the regions’ resilience to the challenges of war and lay the foundations for long-term growth. Increasing the sustainability of transport and logistics infrastructure is possible by combining mechanisms in government policy to create favorable conditions for the restoration of each of its structural elements with tools to stimulate their development in accordance with the priority areas of realizing the export potential of Ukraine’s regions. Based on the results of a comprehensive analysis of the transport and logistics infrastructure efficiency, the article offers a set of the state policy measures of its support and development in the regional socio-economic systems of Ukraine. The main directions of such a policy, in our opinion, should include the expansion of opportunities for realizing the export potential of Ukraine’s regions; diversification of transport and logistics infrastructure development in several complementary priority areas as an element of state economic security; integration of Ukraine’s transport and logistics infrastructure into the world transport system and intensification of Ukraine’s cooperation with international financial organizations to attract international financial assistance for modernization. Ukraine’s active European integration is an important factor in shaping the basis for a qualitative transformation and modernization of the transport and logistics infrastructure, which will open wider access to the EU market and facilitate the use of its opportunities to increase and more effectively realize the export potential of Ukraine’s regions, develop their transport and logistics infrastructure in accordance with EU norms and standards, and expand mutually beneficial partnerships with EU countries in the field of transport and logistics based on national interests. The fullest possible use of the transport and logistics infrastructure in the process of realizing the export potential of Ukraine’s regions will contribute to the rapid recovery and stable development of Ukraine’s economy and increase its competitiveness both in the domestic and foreign markets.

In this study Neem and Yellow oleander biodiesels were blended in some given proportions and characterized. An F165 diesel engine was ran with each blend and its performance parameters evaluated and compared to those obtained when the engine ran on Automotive Gas Oil (AGO). The produced neem oil biodiesel (NOB) and yellow Oleander biodiesel (YOB) were blended together in a percentage ratio of 20:80, 40:60, 60:40 and 50:50 percentages for Neem and Yellow oleander biodiesels respectively. Results show that brake power of the blends is close to that of AGO at lower torques but developed higher power at higher torques (2.69 kWh at 10Nm for N10Y40 and 2.68 kWh for AGO). The blends exhibited close comparison with the AGO in thermal efficiency. The results of the study show a diesel engine perform well with pure biodiesel blends as fuels as it does with fossil AGO, thus new biofuel was produced capable of replacing conventional diesel fuel in the transportation industry.

The article presents an electronic anti-theft protection subsystem that was incorporated into the vehicle control system dedicated to people with special communication needs. The aim of the work was to design and test an electronic subsystem allowing for the acquisition and quick analysis of fingerprint images, checking whether they belong to the vehicle owner and generating a signal allowing the vehicle to be started. The following hypothesis was put forward: it is possible to use artificial intelligence for accurate, automatic classification of fingerprint images acquired in a system with a single-chip microcomputer in order to identify a person. The research niche includes the use of biometrics in electronic anti-theft security adapted to people with special needs. This solution reduces the risk of theft and unauthorized use of special vehicles tailored to the owners' individual needs. The use of a commercial algorithm offered by the sensor manufacturer or the use of artificial neural networks for the classification of fingerprints was considered. The results of research on the accuracy of fingerprint recognition obtained from the developed subsystem are presented. The experiments performed based on the NASNetLarge artificial neural network model confirmed the possibility of achieving recognition accuracy for the test set of 99.99%. Additionally, practical aspects of the applicability of the presented device in an electric vehicle control system supporting the movement of people with physical and/or intellectual disabilities were discussed. The presented solution, after minor modifications, can be used in access security systems for protected rooms, as well as vehicles and military equipment.
Driving techniques for drivers with mobility disabilities.
Authors: Malawko Piotr , Gorska Anna
Published: April 2024

“Driving technique is the way of using the road consciously chosen by the driver. The key to appropriate driving technique is the driver's knowledge, skills and characteristics.” [1] The above-mentioned skills refer only to the manner of using the vehicle by an able-bodied driver (driver candidate and full-fledged driver). The techniques used by the vehicle driver affect the possibility of making mistakes while driving and the time needed to perform manoeuvres. Generally accepted driving standards and principles do not cover how to drive a vehicle adapted to the needs of a disabled driver. These skills are therefore not developed during the course preparing candidates with disabilities to become drivers, or at a later stage after obtaining driving licenses. The aim of the article is to present ways of driving a vehicle using the most common adaptive devices used by people with mobility disabilities. The research used the case study method, i.e. a case study involving the analysis and discussion of real situations [2]. The lack of information relating to driving techniques adapted to the needs of drivers with disabilities is a gap that should be filled. The study describes the processes relating to driving techniques of a vehicle with the most commonly used adaptation sets.
Management of the Development Programme of the Navy – a concept for the Polish Naval Forces
Authors: Pac Bohdan , Pączek Bartłomiej
Published: April 2024

The purpose of this article is to propose a model for planning the development of the naval forces in a medium-sized state through a process of their accurate and effective modernisation, on the example of Poland. Taking up such a subject arises from the delayed results of the current modernisation efforts. In order to achieve the aim mentioned above, it is recommended to solve the research problem by defining a suitable methodology facilitating the planning of naval development. The working hypothesis states that the methodology for the planning development of the naval forces should define a scope of modernisation activities undertaken with the use of tools and methods typical of management and quality sciences. The Allies’ guidelines on acquisition of defence resources stated in the NATO standardisation publications have been also taken under consideration in the research analysis. This modus operandi allows the Authors to fill a research gap in an interdisciplinary approach toward planning the process in question. The study is of conceptual nature. However, it enables the creation of well - aimed and justified programmes for the development of the Polish Naval Forces. The article displays a new perspective in the research analysis, which was formerly conducted by Authors in the years 2020 and 2021, before the Russian invasion of Ukraine.

Building long-term relations with the supplier is one of the key elements in ensuring the high quality of products and the key to the further success of the enterprise. The time of manufacture and the quality of products depend on the work of suppliers. GOST R ISO 9001 - 2015 in No. 8.4 «Management of externally supplied processes, products and services» indicates that any organization regardless of the type of activity or size should define and apply criteria for evaluating, selecting, monitoring and reassessing external suppliers based on their ability to perform processes or deliver products and services as required» [1]. In order to comply fully with paragraph 8.4, the heads of organizations need to pay considerable attention to:  development and implementation of a documented vendor evaluation procedure;  developing, implementing and conducting ongoing supplier audits;  optimization of the time and material input control procedure. These activities allow:  to ensure stability of supply of raw materials, materials and components;  ensure the quality of the products purchased;  optimize input control (by improving the quality of delivered products by the supplier, increasing trust, transparency and openness in working with the supplier, ensuring timely delivery) and, as a consequence, minimize costs at this stage of the process;  to organize a system of traceability of products, raw materials and materials supplied by the supplier;  exchange information and work experience to develop new design solutions;  identify and minimize potentially hazardous risks by working together to address them;  maintain up-to-date information on the supplier, its business activities, management for management decision-making.

This paper presents the results of determining the optimal parameters of selective laser melting (SLM) of the metal powder of the high-temperature alloy VZh-159 (KhN58MBYu). Empirically and using mathematical methods for planning and analyzing experiments to determine the effect of technological parameters of fusion on the tensile strength of the material, rational SLM modes have been established, namely, laser emission power, hatching, scanning speed. The laser power P (X1) and scanning speed v (X2) were chosen as the main variable parameters of the full-factor experimental design, and the tensile strength σB, MPa (Y), was presented as a dependent variable on the selected factors. The mechanical properties of the samples produced by the SLM were determined, which also depended on the volumetric energy density, which is equal to the ratio of the laser power to the product of the scanning speed, hatching, and layer thickness. During the experiment, it was possible to obtain an acceptable quality indicator - mechanical properties, for a certain range of technological parameters of SLM. A study of the microstructure of the material of produced samples of the VZh-159 (KhN58MBYu) heat-resistant alloy was carried out, and chemical and granulometric analysis of the initial powder was carried out.

According to the results of the analysis, it was revealed that the rigid binding of the shell’s parts surface of the skins to the bypass-forming contours of the coverage does not allow us to detect some properties of circulation associated with their internal geometry, regardless of the three-dimensional space of the coverage itself. If the surface of the shell part is sheathed beyond the lines of curvature in specifying orthogonal coordinate lines, then the shape of the stretch punch can be similarly characterized by changing the geometry of the Earth's surface. In this case, the orientability of the surface of the tight punch relative to the main line of curvature along the shaping contour, the direction of which is determined by the direction of the impact during tightening. Such a coincidence is found when monitoring the symmetrical development of focal deformation and the predominant formation of a plastic deformation zone in the foci of partial sheet deformation. As a result of solving the problem of shaping the shell parts of the skins by tightening, which is found to be detected in various sheets of the workpiece and the absence of wrinkles and ruptures.

A water-transport constructions are important ones for Arctic cold climate regions. Ports and waterways in Arctic are used for seasonal delivery of goods and food. Hydraulic structures, such as ports and harbors, play a particularly important role in these regions. When designing berths and other objects in this area, it is necessary to take into account the large amount of the actions, which can be taken from the side of ice. Some of the possible ice impacts are still not reflected in the normative documentation., Ice collar may form around the structure when structures freeze without significant fluctuations in the water level. Ice collar is thicker ice around the structure. This formation can increase the load transferred by the level ice to the structure. However, ice collars are not properly described in the normative documents. Measurement of ice collars and their standardization is an important step towards the development of regulatory documentation containing methods for taking into account the impact of ice collars on structures.

Ice loads, due to large absolute values and diversity, are most important for the calculation of Arctic marine and river structures. The cost of the structure being designed may change several times with a change in the design ice load; therefore, determining the ice load of a given probability is an important task. Some ice formations can significantly change the value of the ice load, but they are not present in the normative documents and standards. Ice collars can be described as thicker ice around heat-conducting structures, which can lead to an increase in loads. However, there is not any method for calculation of ice collar influence on the loads present in the current documents. Ice collar is the reason for thicker ice at the structure-ice contact surface, which lead to an increase in the contact area and can lead to a change in the mechanism of ice failure. In some cases, the presence of an ice collar leads to an increase in the horizontal ice load from the level ice on the structure. The method of discrete elements is considered to solve the problem of the influence of the ice collar on the ice loads. This method allows a time-dependent description of the entire process of destruction of the ice collar. Two-dimension settings are used in vertical and horizontal planes. The relative ice load depending on the thickness of the ice and freezing-degree-days are obtained.

The article describes the potential benefits of implementing and using a digital twin of petrochemical plants as a virtual representation of the production process, including its technological parameters and real-time analytics to ensure an environmentally responsible approach to production. The authors point out the possibility of optimizing production by using sensors and automatic control systems, as well as using the digital twin for testing and refining assumptions. In addition, the implementation of a digital twin in a chemical plant, including with elements of AI, will allow for operational process management. The decision tree proposed by the authors allows a chemical enterprise to reduce its impact on the environment by using a decision support system to manage wastewater treatment at a petrochemical plant. Laborious calculations for forecasting modernization taking into account production, economic, and environmental factors can be obtained using a digital twin not only promptly but also with a specified degree of variation and reliability.
