Authors: Graßhoff Jürgen , Gräfe Christian , Nitschke Friedrich
Published: July 2024

Die Verfasser stellen in diesem Beitrag Vorschläge zur Weiterentwicklung des Kostenmanagements von Produktinnovationen vor. Dabei zielen sie auf die zielkostenkonforme Budgetierung von erzeugnisbezogenen Projektumfängen ab. Anhand theoretischer Vorüberlegungen weisen sie zunächst auf wesentliche Entscheidungstatbestände, aber auch auf Realisierungshindernisse des Kostenmanagements hin. Anschließend unterbreiten sie instrumentelle Vorschläge zur praktischen Durchführung des Kostenmanagements: Durch den Einsatz der strategischen Entwicklungskostenkalkulation lassen sich auf der Basis von technischen Zielparametern eines noch vagen Produktkonzepts die Entwicklungskosten eines neuen Erzeugnisses bestimmen. Mittels Entwicklungsbedarfs-Portfolios können weiterhin Ansatzpunkte zur Senkung der Entwicklungskosten bei Zielkostenüberschreitung identifiziert werden. Querverweise auf den Einsatz der Lösungsvorschläge bei einem deutschen Automobilhersteller belegen deren Umsetzbarkeit.
Fractional elliptic obstacle systems with multivalued terms and nonlocal operators
Authors: Cen Jinxia , Zeng Shengda , Bahrouni Anouar
Published: July 2024

In this paper, we introduce and study a fractional elliptic obstacle system, which is composed of two elliptic inclusions with fractional (pi, qi)-Laplace operators, nonlocal functions, and multivalued terms. The weak solution of fractional elliptic obstacle system is formulated by a fully nonlinear coupled system driven by two nonlinear and nonmonotone variational inequalities with constraints. The nonemptiness and compactness of solution set in the weak sense are proved via employing a surjectivity theorem to the multivalued operators formulated by the sum of a multivalued pseudomonotone operator and a maximal monotone operator.
The effect of phosphorus content in copper alloys used for crystallisers of continuous casting machines
Authors: Smirnov O.M. , Narivskiy A.V. , Ukhin V.Ye. , Tunyk V.O.
Published: July 2024

One of the key elements defining the technical level and operational capabilities of continuous casting machines (CCM) is the complex of physico-mechanical properties of copper or copper alloys used in its production. The paper provides a comprehensive assessment of the possibility of obtaining high-quality copper plates for CCBC crystallizers based on domestic technologies and equipment using refined copper. Special attention was paid to the need to optimize the chemical composition of the copper alloy within a narrower range of chemical element values. The analysis of the research shows that currently used copper alloys for CCM crystallizer manufacturing have a wide range of fluctuations in the main operational properties, namely thermal conductivity (260-390 W/(m·K)) and solidification temperature (250-700 °C). However, most of the alloys used have narrower fluctuation limits for acceptable values, constituting 340-390 W/(m·K) for thermal conductivity and 300-370 °C for solidification temperature, significantly depending on the impurity content in the copper alloy. Generalizing graphical dependencies, it should be assumed that the rational phosphorus content in the alloy is in the range of 40-120 ppm. In this case, the thermal conductivity of the alloy will be in the range of 370-400 W/(m·K), the solidification temperature will be 410-440 °C, and the recrystallization start temperature will be 370-400 °C. Moreover, such a phosphorus content interval is technologically feasible to maintain during billet casting. It is also shown that normalization annealing after cold deformation in the temperature range of 320-350 °C is capable of increasing the thermal conductivity of the alloy by 1-2 %. As a result of the conducted research, optimal limits of phosphorus content in fire-refined copper were established, ensuring the level of its physico-mechanical properties not lower than the indicators characteristic of alloys obtained from cathode copper. However, besides phosphorus, other alloy impurities, the content of which differs from the values characteristic of alloys obtained from cathode copper, may affect the properties of the material made from refined copper. Therefore, further research will focus on studying their complex impact on the physico-mechanical properties of refined alloys.
Analysis of the influence of brake pad material on the formation of defects on the rolling surface of railway wheels
Authors: Sirenko К.A. , Mazur V.L.
Published: July 2024

The results of research and production experience in the field of identifying the causes and mechanisms of defects on the rolling surface of wheels of railway rolling stock are analysed. The article presents different views on the mechanism of influence of brake pad material on the occurrence of wheel surface defects caused by their frictional interaction with pads made of cast iron or composite material in the form of a composite rubber compound. It has been clearly shown that brake pads made of composite rubber compound damage the rolling surface of wheels to a greater extent and more often. This leads to the need to grind wheel sets and reduces their service life. The main cause of defects on the working surface of the wheels is the thermal load on the friction zone between the pad and the wheel during train braking. The temperature in this zone changes periodically and can reach 900 °C, while the self-ignition temperature of the rubber compound used to make the friction element of composite pads is 350-500 °C. The unacceptably high temperature in the friction zone between the composite pad and the wheel surface, which occurs during train braking, is due to the relatively low thermal conductivity of the composite rubber compound compared to the thermal conductivity of cast iron. Equipping the friction element of composite pads with cast iron inserts does not save the situation with regard to the low thermal conductivity of such pads in general and their tendency to damage the rolling surface of the wheels of vehicles. Recommendations have been proposed to improve the technical and economic performance of railway transport by improving the quality of brake pads for vehicles.

revista La Intemperie como discurso de resistencia en la ciudad de Córdoba, Argentina (2003-2007)
Authors: Ulises Delupi Baal
Published: July 2024

Con ánimo de contribuir al eje principal del presente dossier, es decir al tenso diálogo entre los discursos y sus contradiscursos de resistencia para promover una ética de la resistencia, este artículo se propone recuperar las nociones de “contradiscurso” (Angenot, 2010b) y “resistencia molecular” (Brocato, 1986) para analizar la producción intelectual y artística de la revista La Intemperie, en la ciudad de Córdoba, Argentina, en la post crisis social, política, económica y cultural de 2001. Metodológicamente, se procederá a identificar marcas en la materialidad discursiva para establecer regularidades tópicas y temáticas que permitan dar cuenta del modo en que el discurso intelectual opera, bajo ciertas condiciones, como una herramienta política de resistencia contradiscursiva. El material para corpus está compuesto por los primeros tres números de la publicación que resultan relevantes para el análisis. Las conclusiones exponen que el discurso intelectual, nucleado en estas revistas subterráneas y distanciado de los poderes establecidos, disputa el sentido del sistema doxológico que busca imponer relatos simplificadores y únicos.

Authors: Kéri Anita
Published: July 2024

A felsőoktatásban meglévő verseny már nem csupán arra ösztönzi az intézményeket,
hogy hallgatóik egyéni igényeit kielégítsék, hiszen az intézményi siker sokszor
fokmérőjeként emlegetett hallgatói elégedettség mellett a közösségek szerepe is

vonatkozó büszkeségét és márkaközösséghez való tartozásának érzetét az egyetemi
ajándéktárgyak vizsgálatán keresztül. A mélyinterjús kutatás eredményei azt
mutatják, hogy a vizsgált hallgatók egyetem iránti büszkesége megmutatkozhat a
pozitív szájreklámon, a közösséghez való tartozás örömén, és az ajándéktárgyak
viselésén keresztül is. Az alanyok továbbá észlelik az egyetemi és kisebb
alközösségei értékét, magukat a közösség részeként definiálják.
Felsőoktatás-pedagógia a frankofón világban
Authors: Bajomi Iván
Published: July 2024

A tanulmány Észak-Amerika és Európa francia ajkú térségei kapcsán tekinti át azt,
hogy miként került előtérbe a felsőoktatásban dolgozó oktató-kutatók pedagógiai
felkészültségének javítása. Az egyetemi hallgatóság létszámának és
heterogenitásának növekedésén túl Québec tartomány esetében az angolszász minták
erőteljes jelenléte, míg a nagy önállóságot élvező belgiumi és svájci egyetemek
esetében az intézmények közötti verseny és a minőségbiztosítás szerepének
növekedése járulhatott hozzá a vizsgált folyamat térnyeréséhez. A korábban
centralizáltan irányított francia egyetemek esetében viszont csak a 2010-es évek
országos felsőoktatási intézkedései tudták elősegíteni a szóban forgó folyamat
kibontakozását.
A bolognai rendszer kísérlete és kísértése a tanárképzésben
Authors: Hunyady György
Published: July 2024

Az utóbbi évtizedekben két, úgynevezett strukturális reform ment végbe
Magyarországon az általános és középiskolai tanárok képzésében. Az első lényeges
összetevője volt a bolognai elvek bevezetésének a magyar felsőoktatásba,
amelyben a tanári felkészítés választására a szaktudományi alapképzés
követelményeinek teljesítése után került sor. A második reform a 2010-es
kormányváltás után a hagyományosabb osztatlan tanárképzés visszahozását célozta,
korai elköteleződéssel a pálya és két szak mellett. Mindkét esetben alacsony
volt a tanár szakra jelentkezők száma, sőt ez csökkent. A tanulmány a két modell
kombinációját javasolja: a bolognai változat újranyitását is, hogy legyen
további lehetőség jelölteket vonzani a tanári hivatásra az egyetemi tanulmányok
első szakmai tapasztalatai után, és növekedjen a választás szabadsága a
tanárszakok tekintetében (például legyen lehetőség integratív műveltségterületi
szakot vagy szaktárgy tanítása idegen nyelven specializációt választani).

Materials-driven strategies in bacterial engineering
Authors: Paternò Giuseppe Maria
Published: July 2024

This perspective article focuses on the innovative field of materials-based bacterial engineering, highlighting interdisciplinary research that employs material science to study, augment, and exploit the attributes of living bacteria. By utilizing exogenous abiotic material interfaces, researchers can engineer bacteria to perform new functions, such as enhanced bioelectric capabilities and improved photosynthetic efficiency. Additionally, materials can modulate bacterial communities and transform bacteria into biohybrid microrobots, offering promising solutions for sustainable energy production, environmental remediation, and medical applications. Finally, the perspective discusses a general paradigm for engineering bacteria through the materials-driven modulation of their transmembrane potential. This parameter regulates their ion channel activity and ultimately their bioenergetics, suggesting that controlling it could allow scientists to hack the bioelectric language bacteria use for communication, task execution, and environmental response.

Solusi Al-Qur’an terhadap Fenomena FoMO (Fear of Missing Out)
Authors: Sajida Anisa , Jannah Zuhrupatul
Published: July 2024

This research aims to offer a preventive solution to Fear of Missing Out (FoMO) syndrome, which is a syndrome of anxiety caused by the perception that other people have more satisfying experiences than oneself. The fundamental factor triggering the onset of this syndrome is the low level of life satisfaction in a person, which is further exacerbated by the temptation of other people's enjoyment of life on social media. In this case, the researcher examines two verses of the Qur'an, namely Q.S Ibrāhim: 7 and Q.S al-Hājj: 36 to explore and find solutions to the FoMO phenomenon from the Qur'anic perspective. The research method in this article is a literature study that seeks to study and understand theories from various written literature related to the research topic. The results showed that Q.S Ibrāhim : 7 and Q.S al-Hājj : 36 can be an antidote solution to the FoMO phenomenon. These two verses contain the essence of two noble life attitudes, namely gratitude and qana'ah, which are very appropriate to fight the triggering factor of FoMO in the form of low levels of life satisfaction.

Authors: Kim Ye. , Alimbekova A. , Gavrilova А. , Kan А.
Published: July 2024

In the conditions of technological progress and rapid development of information technologies, it is very challenging to prepare specialists in the field of information and communication technologies who would fully possess the knowledge and skills to work with the diverse range of instrumental and software tools and equipment used in the field. This is due to the continuous improvement and updating of programming languages, frameworks, software environments, shells, and hardware. One of the ways to address this issue is through computer-based educational programs, allowing the individualization of the learning process while preserving it’s quality. Currently, there is a large number of computer-based educational programs used in the study of various disciplines. This paper presents the design of a computer-based educational program on the subject "Fundamentals of Computer Modeling," which enables the modeling of random patterns of various natures, ranging from random events to random streams. The educational program consists of three modules, which include a theoretical part on methods of modeling random patterns, testing after each topic, and a calculator for all modeling methods. In each modeling method, you can input any initial data, such as the number of trials, probabilities of events, functions, and parameters of distribution laws. The results of modeling random patterns can be saved as a file. The program interface is available in three languages: Russian, English, and Kazakh. The currently developing educational program aims to improve the learning process in the "Fundamentals of Computer Modeling" discipline and allows learners to study it independently without any interventions from a professor.

The research paper presents a comprehensive study and development of a web-based content sharing system, the main purpose of which is to stimulate and distribute photo and media content, textual information about video game characters in the Ukrainian segment of the Internet through a convenient and efficient platform for users. This study formulated the requirements for the content sharing system and the stages of its development. Based on the requirements for the implementation of the system, a web-based content exchange system was developed, consisting of a client application (frontend) and a web server (backend) using third-party SaaS solutions to store media content and user information for the content exchange system. The system is designed to provide users with a convenient and efficient tool for sharing information about video games. The development process consists of the following stages: researching the context of formulating functional and non-functional requirements, selecting technologies to implement the system in accordance with the requirements for the frontend and backend. Also, unit and end-to-end tests are written for the developed applications to ensure that the system has the expected behavior. Completion of all stages and implementation of front-end and back-end applications in accordance with the requirements is the result of this work, namely a web-based content exchange system that meets all the requirements and provides an effective exchange of information about video games in the Ukrainian Internet segment.
AUTOMATIC SOLVING OF PHYSICS WORD PROBLEMS
Authors: Popov R. , Karpenko N.
Published: July 2024

We present a system that solves simple physics word problems (PWPs) stated in the English language. The main feature of the system is that it is deterministic and yields a correct solution based on real physics formulas. The program generates the solution in a tabular form, showing givens, unknowns, and solution steps.
We performed a thorough analysis on the previous work in this field. Most of the research was accumulated in math word problem (MWP) solvers. We have found that these programs are not capable of solving problems from Ukrainian physics textbooks.
We identified several types of physics problems: theoretical, value conversion, value comparison, unknowns finding, value change. We developed separate problem-solving strategies for each type.
The program uses named entity recognition (NER), a technique in natural language processing (NLP), to identify key elements in the problem text. We created a set of rules for marking these entities. Then, problem type recognition is performed. Depending on the type, the list of entities is converted into the internal problem representation.
Value conversion and comparison problems are easy to handle. We developed a recursive algorithm for solving unknowns-finding problems which turned out to be a simplified version of Stanford Research Institute Problem Solver (STRIPS) algorithm. However, developing a universal algorithm for solving value-change problems presents a significant challenge. We believe this problem type belongs to the NP-hard class, indicating inherent difficulty in finding optimal solutions.
The interface of the program is a web-application. The user can type the problem text and see the solution on a web page. Additionally, the result of NER is presented.
Constructing a general problem solver is challenging. While our program can solve basic physics problems, complex problems involving forces, energy, etc., remain unsolved. However, our solver has great potential for future development. We have thoroughly analyzed its capabilities and limitations and proposed ideas for future research.

Published: July 2024

The development of a voice assistant based on neural systems is an actual line of research in the field of artificial intelligence. Existing voice assistants were analyzed and their advantages and disadvantages were identified in this paper. The following concepts were considered: natural language processing, and neural networks. Different methods of natural language processing significantly increase the quality of work of many programs, because they can interact with people at a natural level for humans without any problems. Modern voice assistants can help millions of people around the world at the same time, regardless of the time of the request. They are covering more and more spheres every year, from ordering food and taxis and making plans for the day to acting as translators.
The types of dialogue systems, the voice assistants` scope of use and their types, recurrent neural networks and data processing models Seq2seq and Transformer, as well as the work of the theoretical component of voice assistants based on neural networks, were considered. Node.js libraries were examined in detail, and an own voice assistant was created and outputs of this system were given. In addition, the possibilities of integrating the voice assistant with other systems and platforms, which expands its functionality and improves interaction with the user, were examined. General theoretical information about voice assistants and their components and principles of work were analysed. An environment for writing a voice assistant was chosen and a practical implementation of writing code for a voice assistant and an example of ready-made code were shown.

Analysis of the machine tool industry of modern Russia based on the «Anna Karenina method»
Authors: Morkovkin Dmitry , Nikonorova Alla
Published: July 2024

The machine tool industry is the most important industry, the state of which largely determines the level of development of mechanical engineering and the national economy as a whole. For the purposes of import substitution, it is necessary, in fact, to rebuild the machine tool industrial complex from bearing factories to machine tool assembly production, mobilize engineering personnel and begin to train new ones. Of course, Russian business alone, without the help of the state, cannot cope with this task. The work carried out a retrospective analysis of the machine tool industry in Russia. In particular, the article presents a table that examines the main indicators characterizing the development of the machine tool market in Russia. Based on the results of the analysis of the metalworking equipment market in the period from 2016 to 2020, a trend of stagnation in the volume of consumption of this equipment and the machine tool industry can be identified. To solve problems in the machine tool industry, it is proposed to use the method of industry mapping of the industry for the purposes of both monitoring the current state and assessing the needs of key enterprises and the industry as a whole in the near future. It is shown that the machine tool industry in Russia has become an excellent example illustrating the «Anna Karenina principle», especially in comparison with the world's largest economies; its current state is the result of many events that are described in the article. The authors are convinced that by producing domestic means of production, from machine tools and equipment to electronic machines, our country is able to provide itself with all the necessary products of its own production — from consumer goods to necessary agricultural equipment and defense products.
Changing the approach to financing health care and education as a basic condition for successful deurbanization
Authors: Rodkin Andrey , Korneva Galina
Published: July 2024

Within the framework of the presented research, the authors examine the current processes of urbanization and existing government policy in relation to small cities, which are defined as the primary area of application of deurbanization; the key basic condition for successful deurbanization is highlighted in the form of standardization in the areas of healthcare and education, and it is proposed to allocate funding for these areas in a separate direction. According to the author, the primary task today is to stop the outflow of population from existing small towns. Such localization of the task allows us to set priorities and move away from slogans to primary measures. The authors are convinced that creating conditions for preserving the population of small towns is of particular importance for the country’s demography, since the demographic transition, that is, a decrease in the birth rate in large cities and megacities, is a global trend that is also true for Russia. It is obvious that the basic conditions for a comfortable life are medicine and education. In this regard, the authors paid special attention to these areas. Attention is focused on the fact that the existing popular opinion among the population and regional elites that all problems will be solved if taxes are left in the regions does not solve the problem, since in this case differentiation will become even more critical. The authors emphasize that the need to change the system of state regional financing and revise the distribution of tax revenues across the country requires a serious and comprehensive assessment, and clearly goes beyond the processes of deurbanization and the problems of small towns

Intricacies of mega and complex projects: a survey of AAMI Park, Australia
Authors: McIntosh Jennifer , Harris Sophia , Taylor Josh Scott , Gharehbaghi Koorosh , Hurst Neville , Tee Kong Fah
Published: July 2024

Complexity science brings together differing paradigms and thoughts. It has attracted academic interest as a means of understanding complex social and technological phenomena. The emergence of increasingly complex building design, construction and technologies is posing numerous challenges for professionals. This paper utilises complexity science, and the practical application of complexity theories, to evaluate holistically the development of a unique major sporting stadium, known as AAMI Park, in Melbourne, Australia. The authors assess the complexity of this project and rank it on a complexity scale to illustrate the level of knowledge and expertise required to deliver such projects. The most dominant and complex feature of AAMI Park, the bio-frame roof, which was innovative at the time, posed unique challenges. Therefore, the authors also evaluate the constraints and specific project delivery methods developed to manage best its complications. Since the adaptive management approach was used for this project, this paper assessed this approach to recommend enhanced delivery methodologies for similar future projects. Further, since the design of this project was the first of a kind, the authors seek to identify the level of project complexity and its success through the lens of complexity theory.

Verlorenvlei is a globally important RAMSAR wetland on the arid west coast of South Africa. A prolonged drought between 2016 and 2021 and increasing competition for water from the agricultural sector resulted in extremely low water levels. We used historical aerial and satellite imagery from 1942 and rainfall and water level data for the past 50 years, to assess habitat changes within the estuarine functional zone of the Verlorenvlei Estuarine Lake. Prior to the drought, lake water levels and water surface area remained stable (1113 ± 27 ha (SE)). Since then, there has been a 64% decrease in open water area, exposing 193 ha of sandbanks, of which 190.9 ha were hyper-sulfidic pyrite-rich. The water in the lower lake was hypersaline (
>100), and in the middle, it was acidic (pH<3). The low water level plus sediment and nutrient input from surrounding agriculture resulted in a localised increase in reeds. Additional pressures, such as fires, have reduced the above-ground biomass of reeds and sedges, potentially altering surface morphology and reducing stored carbon. Despite flooding and filling up in June 2023, the lake remained in an acidic state (3.9–4.3). Similar low-lake level, hypersaline and acidic conditions are predicted to become more common under future climate change scenarios where aridity and extreme weather events are anticipated. Inflow of fresh water into the estuary and control of farming practices are required to keep the Verlorenvlei in a functional state, with long-term monitoring necessary to assess the ecological condition in response to restoration actions.

Este libro de rescate de saberes ancestrales se basa en una investigación etnobotánica llevada a cabo en diversas parroquias de Cuenca, Ecuador. El objetivo principal de este estudio fue preservar los conocimientos ancestrales relacionados con el uso de plantas medicinales. Para cada especie medicinal estudiada, se realizaron investigaciones botánicas y fitoquímicas. Sin embargo, se encontró que dos especies carecían de información sobre sus características fitoquímicas, por lo que se realizaron pruebas de laboratorio para determinar los metabolitos secundarios presentes. Aunque no se descubrieron nuevas especies vegetales durante este proceso, se recopiló información valiosa sobre las propiedades y usos medicinales de las plantas estudiadas. Con base en los resultados obtenidos, se elaboró una guía etnobotánica y fitoquímica que recopila toda la información recopilada de las parroquias estudiadas. Además, se llevó a cabo la siembra de estas especies en el jardín botánico de Cuenca, logrando un total de 79 especies en el área destinada a la huerta medicinal. Para su distribución en el jardín, se dividió el área en bloques y se asignó a cada bloque una categoría de uso de plantas según la etnomedicina. Este libro tiene como objetivo principal rescatar y documentar los saberes ancestrales relacionados con el uso de las plantas medicinales en la región de Cuenca, Ecuador. A través de este estudio, se espera contribuir a la preservación y valoración de estos conocimientos, así como fomentar su integración en los sistemas de salud actuales.

Published: July 2024

In the current world of global food distribution and marketing, the outbreak of a particular foodborne disease in a region may eventually occur in another part of the world at the same time. Foodborne diseases are estimated to cause over 600 million illnesses and 420,000 deaths each year. Listeriosis, a zoonotic bacterial disease caused by Listeria spp. has been reported in various parts of the world’s disease outbreak and incidence. The highest number of diseases and outbreaks is caused by Listeria monocytogenes and is highly predominant among elderly persons, immunocompromised individuals, pregnant women, and infants. This bacterium possesses the ability to survive and multiply under refrigeration temperature, a wide range of pH (4.1 - 9.6), and high salt (≤ 10%). The disease can be minimal (non-invasive/febrile gastroenteritis) and the pathogen possesses the ability to cross the epithelium and infect sterile organs (invasive). Outside food contamination, resistance to antibiotics by Listeria monocytogenes poses major public health concerns as this bacterium has developed resistance to various antibiotics in use. In addition to food, Listeria species have been isolated from the soil, water, plants, fruits, and vegetables coupled with the long incubation period (11 - 70 days), which poses a challenge to infection source identification and trace back principle. Controlling Listeria in foods can be achieved by practicing a Hazard Analysis and Critical Control Point (HACCP) strategy in the food industry, improving hygiene measures, and avoiding the consumption of contaminated foods. Also, susceptible individuals should be educated on the risks associated with the consumption of contaminated foods.

Objective: A water treatment facility is to be erected nearby the industrial tanning complex, recently established East of Cairo, Egypt. This paper represents a contribution to studying the flow characteristics of the produced tannery waste effluents. A dried sample of tannery waste was chemically analyzed by X-ray fluorescence and its particle size distribution was determined. Next, rheological measurements were carried out on the waste slurry produced at temperatures ranging from 10°C to 40°C and three different solid concentrations, by weight: 20%, 25%, and 30%. The results showed that all waste suspensions under all conditions of solid content and temperature behaved as shear-thinning liquids. Flow indices of all suspensions generally tended to increase with temperature and solid concentration. Activation energies for viscosity were correlated to an increase in solid concentration and showed a decreasing pattern. All samples exhibited a thixotropic character that decreased with increased temperature and dilution of the suspension. The maximum pressure drops per unit length of a pipeline used to transport the waste suspension to the treatment unit was evaluated and found to increase with solid concentration and decrease with increasing temperature.

Methods: 5-(3, 4, 5- trimethoxybenzyl) pyrimidine-2-4-diamine known as trimethoprim (TMP), a single crystal is a well-known antibiotic drug, was grown by the slow evaporation method. Findings: The TMP unit cell parameters were confirmed by single crystal X-ray diffraction. Functional groups of TMP crystal was confirmed by Fourier transform infrared spectral analysis. The optical spectrum shows the wide transparency window of TMP which is the prerequisite for NLO material. The band gap is calculated as 4.10 eV from Tauc’s plot. The various optical constants like extinction coefficient, refractive index and reflectance were calculated from the transmittance spectrum data. The optical and electrical parameters like optical conductivity, electrical conductivity and susceptibility of the single crystal of TMP were determined from the UV spectrum. The fluorescence spectrum shows the presence of a sharp intense peak at 690 nm indicates red emission and a weak peak observed at 480 nm indicates blue emission. The Vickers hardness study shows the grown crystal belongs to the soft type single crystal with Meyer’s index (n) of 2. The yield strength of the crystal was calculated. Dielectric constant and dielectric loss are measured as a function of frequency. The laser damage threshold of the TMP crystal was measured using an Nd: YAG laser with a wavelength of 1064 nm. Novelty: The various studies show that the TMP crystal possesses excellent optical properties and can be used for opto-electronics device fabrication.
