Published: January 2025

Abstract: Plant nutrient deficiency detection represents a critical challenge in modern agriculture, significantly im- pacting crop
health, yield, and sustainable farming practices. This survey paper presents a comprehensive analysis of ensemble learning
techniques for automated detection of plant nutrient deficiencies through image analysis. Our research evaluates a hybrid
approach combining MobileNet’s efficient feature extraction capabilities with ensemble methods including Random Forest and
Gradient Boosting algorithms. The methodology encompasses three key compo- nents: feature extraction using MobileNet’s
lightweight architecture for processing plant leaf images, implementation of individual classification models, and development of
ensemble techniques that leverage the strengths of multiple clas- sifiers. Through extensive experimentation and comparative
analysis, our findings demonstrate that ensemble methods consistently outperform individual models, achieving superior accuracy
in detecting nutrient deficiencies across various plant species. The integration of MobileNet with ensemble techniques provides a
robust framework that balances com- putational efficiency with prediction accuracy. This research contributes to the
advancement of precision agriculture by proposing a scalable, real-time solution for nutrient deficiency detection that can be
practically implemented in field conditions, ultimately supporting improved crop management decisions and agricultural
productivity..

Characteristics and Treatment of Effluent from a Ceramic Fiber Products Manufacturing Factory
Authors: Urmaliya Aditya , Nair Dr. Sindhu J.
Published: January 2025

Abstract: Wastewater generated from Ceramic Fiber industry poses serious environmental pollution due to its high chemical
load and complex composition. This study investigates the wastewater generated from the production of various ceramic fiber
products, such as ceramic fiber paper, board, and vacuum formed shapes. As ceramic fiber products provide excellent thermal
insulation and are helpful in energy savings, growth of this industry in future is obvious. Though ceramic fiber production uses
water in a considerable amount, comprehensive wastewater treatment is a necessity to reduce environmental footprint of this
industry. The primary objective of this study was to analyze and characterize wastewater parameters such as Biochemical
Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Dissolved Solids (TDS). In this study, the chemical
treatment utilizes poly aluminum chloride as a coagulant and poly electrolyte as a flocculant. Chemical treatment yields BOD
and COD removal by 70.12% and 73.9% respectively. Further, the aerobic biological treatment provides a reduction of BOD by
77.1% and COD by 63.21%. An advanced oxidation process, ozonation trial was also employed for the evaluation of further
reduction of pollutants to bring them within regulatory limits. The ozonation trail yields BOD and COD reduction by 75.2% and
55.8% respectively.
Measuring Improvement in Fly Ash Based Concrete Impregnated with Glass Fiber
Authors: Chaudhary Er. Ajay Kumar , Sood Dr. Hemant , Rattan Er. Jasvir Singh
Published: January 2025

Abstract: In cement and concrete, fly ash has been utilized as a mineral additive. Utilizing it offers a number of benefits,
including enhanced workability and strength characteristics as well as environmental advantages linked to waste disposal and
lower carbon dioxide emissions. Constantly 1.5%, 2.5%, and 3.5% of the cement's weight is reinforced with alkali-resistant glass
Fibers. Glass Fibers improved split and flexural strength without increasing compressive strength and served as an effective
crack arrester. For this study, concrete of M30 grade is utilized. Studying fly ash's viability as a mineral additive to replace
cement and provide extra glass fibre reinforcement in concrete is the primary goal of this project. Concrete's several structural
qualities, such as its compressive, split, and flexural strength, are satisfied by the use of glass Fibers as extra reinforcement and
fly ash as a partial substitute for cement. The complete investigation came to the conclusion that the best combination of all the
mixes was 10% FA + 3.5% GF, which gave the most tensile strength; 10% FA + 3.5% GF showed greater flexure strength; and
10% FA showed good compressive strength at 28 days compared to standard concrete. After seven days, fly ash blends no longer
exhibit improved compressive strength or split tensile strength.

Published: January 2025

Abstract—This paper aims at identifying the role of lucky EMS comes at the right time to save lives due to its fast flow of events
in today’s world. The services involve transporting client or clients to other relative facilities for diagnosis, stabilization or
further treatment after receiving an emergency call. Although, various parts of the world are experiencing the challenge of
delivering ambulances as fast as possible within the shortest time possible; situations that often come with terrible results. The
advancement in mobile technology is a chance to improve the ambulance service by presenting one with an easier way to call for
help. As the world goes mobile, installing an ambulance services app is a way of closing the gap between the two parties and
ensuring that they get help as early as possible. In today’s ever increasing busy lives, quick response to the need of emergency
medical services becomes very important in saving lives. Emergency ambulance services form the vital link of any health care
delivery system since they bring timely medical care to patients who require urgent care. But then again, many parts of the world
still have to struggle to get their ambulances to respond within the shortest time possible, a factor usually associated with so
many fatalities. In this case the issue of mobile technology presents a way to improve the ambulance services by easing the
process involved in the call for help. By the help of a smartphone an application for ambulance services will create a link
between the user and the facilitating ambulances thereby helping to reduce the response time and hence briefing the
communication gap between the users and the required emergency response.
Comparative Analytical study of GFRP strengthened Deep Beams
Authors: Khan Irshad , Singh Rajkiran
Published: January 2025

Abstract: Deep beams play a very significant role in the design of mega and as well as small structures. Sometimes for
architectural purposes, buildings are designed without using any columns for a very large span. The flexural behavior of deep
beams with and without web reinforcement and strengthened with GFRP strips and steel fiber-reinforced concrete (SFRC) was
investigated in this paper. CFRP has been used extensively for strengthening of RCC structures. In this study GFRP strips are
used as an alternative. GFRP strips have been used in place of CFRP strips. The four-point flexural response of one reference
beam strengthened with high-performance fiber-reinforced concrete was investigated by carrying out a FEM analysis using
ANSYS software and comparing it with theoretical calculation done as per ACI code using Strut Tie Model. The analytical and
theoretical data (strain, load, etc.) are compared and discussed. For comparison the results from an earlier study [11] on CFRP
strengthened deep beams is used as a reference.
The RC and SFRC deep beams showed formation of compression struts. The deflection and shear stress values for FRC deep
beam were comparatively lesser than RC deep beam and an increase in load carrying capacity was observed with reduced
deflection. It was observed that the GFRC strengthened deep beams produced better results than the CFRC strengthened beams.
SFRC-GFRP strengthened deep beam showed the highest ultimate load value compared to other options. While values of
deflection were reduced in both GFRP strengthened RC and SFRC deep beams. RC-GFRP, SFRC- GFRP strengthened and
SFRC showed reduction in shear stresses compared to RC deep beam.The study suggests that GFRP strengthened FRC deep
beam is a better alternative to RC deep beams as it has better ultimate strength and shear stress values compared to RC deep
beams and GFRP being an economical and sustainable option can be an alternative to strengthening with CFRP wraps

An Efficient Smart Flood Detection and Alert System based on Automatic Water Level Recorder Approach using IoT
Authors: Mansi Joshi  , S. Murali
Published: January 2025

An innovative flood detection system may track an increase in water levels. Deployed in cities or other areas of interest, the system consists of sensors. Both mains energy and solar power are viable options for the sensors. To detect impending flooding promptly, a flood warning system uses reliable and up-to-date sensing equipment such as rain gauges, water level sensors, and flow rate sensors for the smart alert system. The challenging characteristics of smart flood detection and alert systems are that some people may not be able to access the warnings, and flash floods may happen too quickly for a warning to be adequate. Hence, in the proposed method, the Automatic Water Level Recorder enabled the Internet of Things (AWLR-IoT), which integrates a low-cost cloud to overcome the challenges of the smart flood detection and alert system and increase optimization modelling and efficiency. Among the most destructive natural catastrophes that may happen on Earth is flooding. After that, a Wireless Sensor Network (WSN) is used to accomplish the flood prediction utilizing data from sensors enabled by the Internet of Things. Heavy rainfall and the following water outflow cause flooding in nations with certain climate conditions. The system monitors humidity, temperature, water level, water rise rate, and rainfall to identify when a flood is imminent. The function of the AWLR-IoT sensor is for monitoring and recording in a database with real-time sensing. This research shows that the low-cost AWLR-IoT sensor has reduced processing time compared to conventional data processing.
Material selection and performance analysis of RF-MEMS switch for MM-WAVE applications
Authors: R. Karthick  , S.P.K. Babu  , B. Balaji
Published: January 2025

This paper presents the design, simulation, and investigation of a fundamental structure for capacitive MEMS switches in a shunt configuration. The main objective is to select materials that achieve low actuation voltage while maintaining RF and dynamic performance, especially for mm-wave applications. The proposed design consists of a Fixed-Fixed flexure beam with dimensions of 260 μm in length, 100 μm in width, and 0.5 μm in thickness. Considering the impact of squeeze film, 60 holes are integrated into the beam membrane, each measuring 64 μm² (8µm x 8µm), and a final gap of 1.9 μm is implemented. The suitability of materials for the beam membrane and dielectric layer in capacitive MEMS switches has been thoroughly examined through a combination of theoretical analysis and software simulations. Aluminum (Al) has emerged as the ideal choice for the beam membrane in mm-wave applications. This preference is defensible by its simulated results to offer a low pull-in voltage of 4V, a quality factor of 1.18, and a switching time of 67 microseconds. Similarly, Si3N4 has been identified as appropriate material, offering a upstate capacitance of 91fF and a downstate capacitance of 7.1pF.
Modeling of thermal stresses on steel beam
Authors: Dalipi Bashkim , Syla Naim , Aliaj Fisnik , Zeqiraj Arbër
Published: January 2025

When a metal separates two environments with different temperatures, then because of the temperature gradient in the metal, thermal stresses will appear. To address this phenomenon, we will take the example of a steel beam, which is part of a metal construction. The geometry of the beam is regular and one end of it is subjected to a continuous emission of heat (for example, it is close to the oven) while the other end is in contact with the surrounding external environment. For simplicity, we will assume that the heat emission is constant, so the temperature of the edge of the beam is also constant. Likewise, for the temperature of the other end, we will assume that it is constant. Let the temperature of the first end be , while that of the second end is , then the difference  causes the flow of heat, respectively the occurrence of thermal stresses. Mathematically, heat flow is described by a differential equation in the temperature field, while the functional dependence of the deformation is described by a differential equation in the field of structures - Hooke's law. So, we have two differential equations from two fields: thermal and structural. We have solved them with the finite element method in temperature-structure coupled field, while the simulation in ANSYS. The algorithm of the FE method and the simulation in ANSYS prove that the treatment can be done for other integration conditions (geometry, material and different temperatures).
Techniques for load balancing throughout the cloud: a comprehensive literature analysis
Authors: Nimmy Francis  , N. V. Balaji
Published: January 2025

Recently, "Cloud-Computing (CC)" has become increasingly common because it's a new paradigm for handling massive challenges in a versatile and efficient way. CC is a form of decentralized computation that uses an online network to facilitate the sharing of various computational and computing resources among a large number of consumers, most commonly referred to as "Cloud-Users (CUs)”. The burdens on the "Cloud-Server (CS)" could be either light or too heavy, depending on how quickly the volume of CUs and their demands are growing. Higher response times and high resource usage are two of the many issues resulting from these conditions. To address these issues and enhance CS efficiency, the "Load-Balancing (LB)" approaches are very effective. The goal of an LB approach is to identify over-loading and under-loading CSs and distribute the workload accordingly. Publications have employed numerous LB techniques to enhance the broad effectiveness of CS solutions, boost confidence among end CUs, and ensure effective governance and suitable CS. A successful LB technique distributes tasks among the many CSs within the network, thereby increasing performance and maximizing resource utilization. Experts have shown an abundance of engagement on this issue and offered several remedies over the past decade. The primary goal of this extensive review article is to examine different LB variables and provide a critical analysis of current LB techniques. Additionally, this review article outlines the requirements for a new LB technique and explores the challenges associated with LB in the context of CC. Conventional LB techniques are insufficient because they ignore operational efficiency and “Fault-Tolerance (FT)” measures. The present article, to bridge the gaps in existing research, could assist academics in gaining more knowledge about LB techniques within CC.

Published: January 2025

Aim: In this study, DNA barcoding of Rhophalosiphum nymphaeae was conducted using a population collected from five different aquatic host plants, and the genetic diversity analysis was performed.

Methodology: Genomic DNA from R. nymphaeae adults was extracted and the COI gene was amplified using PCR. The PCR products were sequenced, analyzed for identification using NCBI and BOLD databases, and the sequences were submitted to NCBI GenBank. Further genetic analysis were conducted to study the genetic diversity of the pest.

Results: Two new aquatic weed hosts of water lily aphid was reported from India, i.e., Blue water lily, Nymphaea nouchali Burm. f., and Four leaf clover, Marsilea quardrifolia L. The genetic diversity analysis revealed the lesser diversity among the Indian and USA population of water lily aphid as compared to the populations from China, Canada and Lithuania.

Interpretation: The genetic diversity analysis indicated no genetic variation in the Indian population, however, a moderate level of variation was observed in the rest of the world population. This work will facilitate the quick identification of R. nymphaeae independent of sex and stage, furthermore helping in either pest management or its use as bio-control agent.

Historiosophical Aspects of Vyacheslav Ivanov’s Interpretation of “The Legends of the Grand Inquisitor”
Authors:   А.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Anokhina Yuliya Yu.
Published: January 2025

The article discusses the notes from Vyach’s Ivanov lecture about “The Legend of the Grand Inquisitor” (1938). Using the example of the specifics of Ivanov’s understanding of the historiosophical ideas expressed in the “poem”, the question of the methodological features of Ivanov’s interpretation is explored. It is shown that the lecture notes reflected the approach to the novel “The Brothers Karamazov” as a dialogical work. The principle of dialogism is revealed, on the one hand, thanks to a historical and literary analysis of the form of the legend, the genesis of its plot and the ideas embodied in it. The principle of dialogism is revealed, on the one hand, through the historical-literary analysis of the legend's form, the genesis of its plot, and the ideas embodied in it, and on the other hand, through the clash of viewpoints of the characters (Ivan Karamazov and Alyosha, Ivan Karamazov and Elder Zosima), as well as the worldview perspectives of the author of the poem (Ivan Karamazov) and the author of the novel “The Brothers Karamazov” (Fyodor Dostoevsky).

Authors: Azizah Alviana Inas , Wijayanti Pini , Syaukat Yusman
Published: January 2025

Poor air quality is a major issue in the core city of the Jabodetabek urban agglomeration, Jakarta. Unfortunately, this problem is not limited to Jakarta. Other cities in Jabodetabek also face similar challenges, where they have experienced similar fluctuations in their annual average PM2.5 concentrations based on historical data. This indicates that the air quality problem is dependend on the region. The integration of systems and activities among these cities may explain this problem. This spatial dependency is dangerous and can lead to transboundary health effects. Therefore, this research aims to find evidence of this spatial dependency in Jabodetabek. The results show that PM2.5 concentration in Jabodetabek is spatially dependent and exhibits a clustered pattern. The highly concentrated core of the cluster is Depok, the connecting city between the buffer cities and the core city of Jabodetabek. Cities with high-point and mobile hotspot sources, such as South Jakarta, East Jakarta, Bogor, and Bogor City, surround Depok, leading to this concentration.

This article examines marketing factors and elements that influence customer equity associated with building sustainable relationships with profitable clients, which are attracting increasing interest from marketers. Recently, consumers have acquired technical opportunities to influence brands more actively and traditional marketing methods and means often do not ensure the success of the company. In today's conditions, price competition and mass advertising are losing their power of influence, so companies are looking for new methods to fight for the customer attention. Building relationships between the company and the consumer and retaining existing consumers is of great importance. One of the most promising research areas in marketing is the development of customer equity. A basic assumption of customer equity is that a customer, like any other asset, is a financial asset. Customer equity is the total discounted lifetime value of all the company's customers. It helps measure the financial returns that can be made from all customers over the course of a relationship. This enables businesses to assess the value of their clients' assets and make sound financial decisions. By evaluating empirical studies and examining contemporary trends, the article provides both theoretical insights and practical guidance for marketers. The objective is to uncover the impact of marketing factors on customer equity, offering valuable resources for academics and practitioners. As a result of the article, the opinion of various factors and conceptual models influencing customer equity are summarized.

The problems of the profession of communication specialists in the processes of local government changes after the administrative territorial reform in Latvia
Authors:   Turiba University, Bunkus Jana , Cane Renate ,   Turiba University
Published: January 2025

In recent decades, Latvia has been affected by several administrative and territorial reforms, the last of them in 2021. Consequently, 43 new municipalities were created instead of the previous 119 municipalities. One of the reform's goals was to reduce local governments' administrative costs, which meant reducing the number of deputies and employees, including communication specialists. However, reorganizing the work processes of the new administrative territories created new professional challenges for the municipal communication specialists, as there was a need to explain these often problematic processes to the public. The study aims to identify the problems of the profession of communication specialists in the processes of changes in local governments after the administrative-territorial reform in Latvia. Research question: what are the most common problems in the professional activities of communication and public relations specialists of Latvian municipalities in the period after the implementation of the administrative-territorial reform? Both qualitative and quantitative data collection and analysis methods are used in the research. A survey of these specialists was conducted to clarify the professional activity problems of communication specialists, which have arisen under the influence of the municipal change process. The results of the focus group discussion supplemented the survey results and showed the nature of the problems by looking at them from a deeper perspective. The interviews of local governments and communication experts provided insight into public relations and communication problems in the industry, both in local governments and in Latvia as a whole. As a result of the study, the authors conclude that, in general, the administrative-territorial reform in Latvia has mainly addressed issues of an economic and infrastructural nature. In such a situation, the role of vital professional communication specialists is increasing. Currently, it can be observed that, in general, communication specialists' involvement in managing municipal change processes in Latvia is low. It is hindered by factors such as the lack of understanding on the part of the municipal administration, as well as the inconsistency of the skills and knowledge of public relations specialists.

The article examines the issues of social responsibility and sustainability reporting by higher education institutions (HEIs) and conducts an empirical study of the reports of four Lithuanian public colleges - participants of the United Nations Global Compact (UNGC). The aim is to identify the current state of the reporting of Lithuanian public colleges and prepare for changes. The problem stems from the fact that, in recognition of the importance and relevance of HEIs to the achievement of the Sustainable Development Goals and the implementation of the Ten Principles of the UNGC, there is no unified reporting framework for HEIs. A review of previous research and an empirical study also highlighted the problem. The methodology includes analysis of scientific publications and official documents, as well as quantitative methods such as clustering of report data, analysis of content volume and structure. The findings of the study are as follows: HEIs' reports vary in both form and content; it is difficult to compare information for a lack of common indicators; HEIs focuses on the fundamental Ten Principles areas that are important to them. However, the reports show the strategic attitudes of higher education institutions and disclose practical activities and achievements. This is the first summative study showing the current state of sustainability reporting of Lithuanian public colleges, UNGC participants. It can be used to improve reporting; the dissemination of the results can be useful for other HEIs, UN Global Compact participants, in preparing for the 2024 Communication on Progress and beyond.

Background/Aim. Expectancies about the effects of cannabis have been related
to the onset and frequency of its consumption. One of the most used
instruments to measure cannabis effect expectancies is the Marijuana Effect
Expectancy Questionnaire (MEEQ). The aim of this study was to determine the
psychometric properties of the Serbian adaptation of the MEEQ among
secondary school pupils. Methods. The retrospective study included 1,642
secondary school pupils (52.3% female) from the South Backa District,
Vojvodina, Serbia. In addition to the MEEQ, the Cannabis Use Intention
Questionnaire (CUIQ) was also used, as well as a self-report measure of
cannabis use. Results. The original six-factor MEEQ model showed the best
fit indices with the following factors: Cognitive and Behavioral Impairment,
Relaxation and Tension Reduction, Social and Sexual Facilitation, Perceptual
and Cognitive Enhancement, Global Negative Effects, and Craving and Physical
Effects. All MEEQ scales showed positive and expected correlations with the
CUIQ scales, among which the highest correlation was with the Attitudes
toward Consumption scale. Correlations with self-report cannabis use were
significant for all MEEQ scales, except for Cognitive and Behavioral
Impairment. Conclusion. The results suggested good psychometric properties
of the Serbian adaptation of the MEEQ. The results also confirmed the
originally proposed factor structure, good reliabilities of the scales?
scores based on internal consistency, as well as convergent and criterion
validity.
Antoninian Treboniana Gallusa z cmentarzyska ludności kultury wielbarskiej w Weklicach na tle innych monetarnych znalezisk z Barbaricum
Authors: Sidarovich Vital , Baczewski Marek , Natuniewicz-Sekuła Magdalena
Published: January 2025

W artykule omówiono monetę rzymską z III w. – perforowany antoninian cesarza Treboniana Gallusa, znaleziony w 2022 r. podczas badań wykopaliskowych na cmentarzysku kultury wielbarskiej w Weklicach, w zniszczonym grobie inhumacyjnym nr 642. To czwarta moneta rzymska pozyskana na tej nekropoli, ale pierwsza o tym nominale. Antoniniany są licznie znajdowane w północnej części obszaru kultury wielbarskiej, w tym na Wysoczyźnie Elbląskiej. Ich odkrycia rejestrowane są także na innych obszarach Barbaricum, ale rzadko w grobach, gdzie dominują denary i subaeraty, w większości z otworami. Moneta z Weklic to drugi antoninian odkryty w grobie ludności tej kultury, ale pierwszy z perforacją. Prawdopodobnie używana była jako amulet lub ozdoba w postaci zawieszki.
Wahania klimatyczne w III w. p.n.e. - V w. n.e. i ich wpływ na relacje człowiek-środowisko na wybranych przykładach z południowej Polski
Authors: Dobrzańska Halina , Kalicki Tomasz
Published: January 2025

Na tle wahań klimatycznych w Europie przedstawiono cztery przykłady szczegółowych studiów z południowej Polski, które dokumentują bardzo wyraźny, wielokierunkowy wpływ zmian klimatycznych w okresie rzymskim na osadnictwo i charakter aktywności społeczności kultury przeworskiej. Istotną rolę odgrywały też uwarunkowania lokalne. Omawiana ekumena nie była jednolita, co powodowało regionalne zróżnicowanie antropopresji, zapisane w formach i osadach. Składały się na nią „centra” produkcji pozarolniczej, tj. metalurgiczne w regionie świętokrzyskim i ośrodki garncarskie w dolinie Wisły, na wschód od Krakowa, relatywnie gęsto zaludnione i znacząco oddziałujące na środowisko przyrodnicze. Pomiędzy tymi centrami, zajmującymi stosunkowo niewielki obszar, rozciągały się tereny użytkowane rolniczo, stanowiące mozaikę gruntów ornych, pastwisk i obszarów leśnych, co powodowało niewielką intensywność procesów erozyjno-akumulacyjnych.Niezależnie od wielkich ruchów migracyjnych ludności kultury przeworskiej na południe, heterogeniczność ekumeny mogła powodować również lokalne przemieszczenia do obu centrów produkcyjnych (odpowiednik współczesnych migracji „wieś→miasto”). Może to ilustrować spadek gęstości zaludnienia niektórych obszarów rolniczych, np. doliny Nidy i jej lewobrzeżnej, krasowej części zlewni po rzymskim optimum klimatycznym (po 150 r. n.e.).

Artykuł dotyczy skarbu wczesnośredniowiecznych grzywien srebrnych z miejscowości Bużyska, gm. Korczew, w pobliżu Drohiczyna. Przedmioty ukryte w 2 poł. XII lub 1 poł. XIII stulecia odnaleziono w 2005 r., podczas badań wykopaliskowych na terenie wielokulturowej osady (stan. 10/54, na obszarze AZP 53–81). Zespół składał się z 11 grzywien srebrnych, z których 10 należy do tzw. typu  czernihowskiego, a jedenasta to sztabka litewska, zwana też zachodnioruską. W tekście zamieszczono opis okoliczności odkrycia oraz charakterystykę typologiczną i dane metryczne (wymiary i wagę) odnalezionych sztabek. Zaprezentowano również wyniki analiz składu pierwiastkowego metalu, z którego odlano przedmioty. Badania wykonane metodą SEM-EDS, ze względu na niewielką liczbę przeprowadzonych dotychczas analiz specjalistycznych, będą miały duże znaczenie dla przyszłych studiów nad grzywnami.
Józef Łepkowski (1826–1894) i początki polskiej archeologii uniwersyteckiej
Authors: Woźny Marzena
Published: January 2025

W XIX w. archeologia uniwersytecka na ziemiach polskich rozwijała się na Uniwersytecie Jagiellońskim i w znacznej mierze związana była z Józefem Łepkowskim (1826–1894). Był on pierwszym profesorem archeologii na terenie Polski podzielonej wtedy między trzy zabory. W 1863 r. uzyskał habilitację, trzy lata później został mianowany profesorem nadzwyczajnym, a w 1875 r. profesorem zwyczajnym. W swoich wykładach prezentował zagadnienia dotyczące nie tylko pradziejów, ale również historii sztuki, konserwatorstwa i nauk pomocniczych historii. Był organizatorem uniwersyteckiego Gabinetu Archeologicznego, w którym gromadził dzieła sztuki i różne zabytki archeologiczne. W artykule ukazano okoliczności i kulisy zdobywania przez archeologię statusu dyscypliny uniwersyteckiej na ziemiach polskich w XIX w. oraz wkład w tym zakresie tytułowej postaci.
