Authors: Prysiazhniuk O. I. , Maliarenko O. A. , Lazdiņš A. , Musich V. V. , Honcharuk O. M.
Published: December 2024

Purpose. To determine mathematical models suitable for yield prediction of bioenergy crops and to establish the patterns of the crop health monitoring.
Methods. Field studies were conducted in the zone of unstable soil moisture (Experimental Field of the Institute of Bioenergy Crops and Sugar Beet NAAS of Ukraine, Ksaverivka Druha, Kyiv region) and sufficient soil moisture (Yaltushkiv Experimental Breeding Station of the IBCSB NAAS of Ukraine, Chereshneve, Vinnytsia region) in the Right-Bank Forest Steppe of Ukraine in 2022−2024.
Results. Frosts can destroy new giant miscanthus sprouts and reduce crop yield by 15.5% in the sufficient soil moisture zone and by 22.4% in the unstable soil moisture zone. Additionally, under the conditions of unstable soil moisture, yield formation of giant miscanthus is limited by insufficient soil moisture, as miscanthus plants can efficiently use only 20 kg/ha of nitrogen fertiliser. In this case, the yield of giant miscanthus can be predicted using the equation: y = 15.19 + 0.29X – 0.005X². Meanwhile, under the conditions of sufficient soil moisture, small doses of fertilisers do not limit the linear biomass growth function, and the equation for yield prediction is: y = 18.44 + 0.25X.
Conclusions. For yield prediction in the specific region, it is advisable to use the regression model proposed by Vossen, which takes into account the average yield, linear time trend, and linear regression function. For a specific agroclimatic region, the potential yield of bioenergy crops could be determined by a formula that considers the total land area of the region, the share of bioenergy plantations, and the predicted yield for the specific conditions of the region. Yield prediction model for bioenergy crop consists of the following levels: (1) determining the areas of bioenergy plantations in the GIS map of the region, specifying the plantation age and the varieties used; (2) refining environmental conditions (soil type, moisture regime, and mineral nutrition); (3) weather observation; (4) vegetation index observation; and (5) yield modelling.

Moderating the Soft Storey Impact in Multi-Storey Buildings: A Comparative Seismic Investigation
Authors: K Shabla , Praseeda K.i. , Pany Chıtaranjan
Published: December 2024

A storey with lateral stiffness less than 70% of the storey above or less than 80% of the average stiffness of the three storeys above is considered a soft storey. Ground-floor open-air buildings are frequently used for parking, particularly in metropolitan settings with considerable space limits. Soft-story buildings with irregular stiffness tend to collapse more than conventional buildings. The study's main goal was to understand better the soft storey effect in multi-storey structures and how to mitigate it using strategies such as adding shear walls, bracings, viscous dampers, and stiffer columns. A G+14 storey building finite element model (FEM) has been established via ETABS software and performed Response Spectrum Analysis at three seismic zones-III, IV and V. To determine the best method for reducing the soft storey effect in buildings, an analysis is conducted taking into account many parameters, including storey shear, stiffness, storey drift, and storey displacement for the entire structure, as well as the responses at the soft storey level for different configurations. According to the findings, adding a shear wall to a soft-storey building increases storey shear while reducing maximum displacement and storey drift. The first floor of the structure (soft storey) exhibits the most significant reduction in displacement (79.29%) and storey drift (79.3%) when shear walls are incorporated at the corners. There is also a 33.11% increase in base shear at the first story level, and the structure's stiffness increases by 6.5 times compared to a soft storey building. Adding a shear wall reduces the soft storey building's maximum displacement and storey drift by 25.27% and 59.28%, respectively. The soft storey building's maximum storey shear rises by 33.38%. Regarding seismic performance, a soft-storey building with a shear wall performs better than other soft-storey mitigation techniques.
Flexural behavior of sustainable high-strength RC beams with GGBS and iron filings incorporation
Authors: Hassan Sawsan Akram , Altai Saif
Published: December 2024

This experimental study investigates the behavior of sustainable high-strength reinforced concrete (HSRC) beams when cement is partially replaced with ground granulated blast furnace slag (GGBS) and sand with iron filings (IF). Eight rectangular HSRC beams were experienced to four-point loading to examine the effects of these substitutions. The cement was replaced with GGBS at three percentages (10%, 30%, and 50%), with and without a 10% substitution of sand by IF. The results showed that substituting 30% GGBS caused a minor reduction in beam strength, while higher GGBS percentages (above 30%) led to a more significant decrease. However, adding 10% IF improved the beams' strength, demonstrating its potential as a reinforcing material. All beams exhibited similar failure patterns under peak loads.
Similarly, the load-deflection behavior of all beams showed consistent patterns across different configurations. However, beams of an optimum replacement consisting of 30% GGBS and 10% IF can support larger values of load-carrying capacity, moment-resisting capacity, and energy absorption than those with other mixtures. The study shows that while GGBS could enhance sustainability, it should be judiciously adopted to maintain structural integrity. Contrariwise, IF shows excellent potential in improving the HSRC beams with improvement in sustainability. It tends to create a balance in material substitution to optimize performance and environmental impacts in concrete structures.
STRATEGIC MANAGEMENT DISCOURSE OF TOP-LEVEL MANAGERS: AN ANALYSIS OF THE MARITIME INDUSTRY IN TÜRKİYE
Authors: Gökmen Gökhan , Ayaz İlke Sezin
Published: December 2024

In today’s globalised and technologically advanced business landscape, businesses experience various challenges in securing future success. The maritime industry is among the sectors profoundly impacted by global shifts, necessitating decision makers to enhance and adapt their strategic management practices to navigate these challenges effectively. Despite the crucial role of strategic management in the industry, the literature lacks sufficient documentation of decision makers’ perceptions, approaches and practices related to strategy. This study addresses this gap by analysing top managers’ strategic management discourse. Using a dataset of 68 published interviews, the authors employed deductive content analysis based on a novel strategic management keyword dictionary. This process identified 56 keywords categorised under six distinct themes: Government and Markets, Positioning, Performance, Growth, Technology, and Human Resources. The findings revealed that top managers in Türkiye’s maritime industry placed the greatest emphasis on the Government, Markets, and Positioning themes. While top managers’ strong awareness of global environmental challenges signalled the industry’s awareness of sustainability issues, the fewer codes in the ‘Human Resources’ and ‘Technology’ themes suggested top managers’ limited attention to the working environment, required skills, and management styles. Future research can expand on this study by incorporating additional maritime industry-related magazines and publications and provide broader perspectives.

Authors: Okumuş Fatih , Kanun Engin
Published: December 2024

While the maritime transportation sector plays a critical role in the global economy, it also significantly contributes to greenhouse gas emissions. This study examines the energy efficiency, technical feasibility, and environmental impacts of ammonia as an alternative fuel in maritime transportation. The contributions of regulatory initiatives, such as the IMO's Energy Efficiency Existing Ship Index (EEXI) and the EU's FuelEU Maritime initiative, in promoting the use of low-carbon fuels to reduce emissions are discussed. The study evaluates the chemical and physical properties of ammonia, challenges associated with its combustion and production processes, with a focus on integrating renewable energy sources for green ammonia production. Findings suggest that ammonia's low reactivity and wide availability make it a promising sustainable fuel. However, overcoming challenges such as combustion difficulties and toxicity will require technological advancements. This comprehensive analysis provides an in-depth perspective on the potential contributions of ammonia to achieving decarbonization goals in the maritime sector, as well as the obstacles that must be addressed.
Kelbessos: A Military Settlement as Termessos’ Peripolion
Authors: Çevik Nevzat
Published: December 2024

Kelbessos is located in the area of Ağırtaş / Ağıltaş, 23 km west of Antalya. It is at the border of Pisidia, Lycia, and Pamphylia. The fortified citadel (phrourion) was established as a military settlement within the chora of Termessos, so was a garrison with the status of peripolion of Termessos. The settlement of Kelbessos has the structure of a mountain fortress in the nature of a “demos” rather than a fortified settlement. There are ruins in the settlement from the Hellenistic Period to the Byzantine Period. It experienced its brightest time during the Roman Period. Military buildings, religious buildings, a small number of residences, graves, cisterns, and workshops were identified in the settlement. The most important building in Kelbessos is a Principia, unseen in other settlements of the region. This military administration building reflects the military, political and urban status of Kelbessos. Ruins that could be an agora and a temple have been identified by us. Epigraphic and archaeological finds show that Artemis Kelbessis was the primary god of the city. Phallos reliefs and cult niches are other data obtained about its religious beliefs. The settlement’s necropoleis evidence various grave typologies including sarcophagi, monumental tombs, chamosoria, and rock-cut osteotheks. Kelbessos was an ancient settlement that underwent gradual change but did not undergo true urbanization. Rather it remained a secondary military provincial settlement throughout its history. Considering the construction techniques of the fortification walls surrounding the settlement, they were built during the Hellenistic Period, especially in the third-second centuries. The peripolion of Kelbessos was a permanent garrison in the territory of Termessos from the Hellenistic Period onwards. It served both as a part of the city’s defense system and as a safe, fortified citadel where the inhabitants of the surrounding countryside could take refuge in times of need.
Bricks and Roof Tiles of Alanya Castle: Evaluation of Animal Footprints from an Ichnoarchaeological Perspective
Authors: Yıldızlı Mustafa
Published: December 2024

The use of bricks and roof tiles was prevalent during the ancient era. Brick production could be established wherever suitable clay was available. However, the production methods and demand for bricks varied regionally. In settlements abundant in stone, brick usage was minimal, while in regions with few stone resources, brick usage was widespread. The architecture of Alanya Castle prominently features
the use of bricks, especially in the construction of the corner baths and large cisterns in the Inner Castle. Shops within the Middle Wall, such as the Seljuk Bath, Old Bazar (Arasta) and Old Bazaar (Bedesten), were also partially constructed with bricks. Due to its geographical location, Alanya Castle served as a bustling port city during the Hellenic, Roman, Byzantine (Eastern Roman), Seljuk, and Ottoman periods. There are no written records indicating whether the brick trade took place during these periods. This study aims to determine the formation process of imprints found on the bricks and roof tiles discovered in the excavations of Alanya Castle. It also seeks to interpret which animals these imprints belonged to and to analyze data regarding the local production of bricks. The study will therefore, contribute to ongoing ichnoarchaeological research. Imprints of both human and animal footprints, as well as those created by plants, can be found on bricks and roof tiles. In Alanya Castle, 22 bricks and one roof tile with animal footprints were identified and examined. The imprints belong to dogs, wild and domestic goats, and jackals. The most common group of imprints is from canids, particularly dogs. Imprints of wild goats and domestic goats represent another significant group on the castle’s bricks. Wild goats still reside in Alanya Castle today. Its steep rocky terrain, along with the presence of shrubs, has provided a suitable environment for these animals. This study aims to shed light on the formation of imprints on bricks and roof tiles found in Alanya Castle. It offers valuable insights into ichnoarchaeological research, while also providing information on the potential local production of bricks during different historical periods.
Some Thoughts on the Julio-Claudian Period of Nysa ad Maeandrum in the Light of a Private Portrait from the City
Authors: Keskin Hava , Öztaner Serdar Hakan
Published: December 2024

The Carian city of Nysa ad Maeandrum was established during the Early Hellenistic period. Strabo mentioned the city where he was educated in his youth, defining Nysa as a dipolis - a double city. Excavations carried out in the city have unearthed a network of streets, numerous buildings, and sculptural fragments. The subject of this study is a marble head recovered as spolia in a Late Antique building located at the intersection of Street 1-plateia (western part) and Street 6W. Despite some discrepancies, the head is coherent with the male portrait types of the Julio-Claudian family. In this context, it represents a private portrait reflecting the public honoring practice of Nysa. The evidence for that period in the city is limited, and the existence of monumental buildings is known by indirect sources, mainly from Strabo’s accounts. Besides the public honorings of civic officers, imperial honoring is attested by an inscribed statue base. Numismatic data indicate the Nysaeans’ gratitude for Tiberius and provides insight into the city’s social context during the Julio-Claudian period. The typological classification of the marble head makes it the first Julio-Claudian sculpture of the city and sheds light on Nysa’s history during that period.

Authors: Kenzheali Yerkezhan , Makhmetova Anar
Published: December 2024

Agriculture is a key sector in Kazakhstan's economy, contributing significantly to employment and GDP. However, geographic, climatic, economic, and policy-related factors contribute to substantial regional differences in agricultural performance. This paper aims to assess the level of agricultural development across Kazakhstan's regions using an integral index based on key variables that influence productivity, such as soil surface temperature, producer price indices, total sown area, employment figures, and domestic R&D expenditure. The paper used the following methods: correlation analysis to determine the relationship, regression analysis after filtering variables, integral index for a generalized assessment of agricultural productivity by region, and cartographic analysis. The findings highlight significant geographical variations, with regions like Almaty and Turkestan showing high productivity, benefiting from favorable climatic conditions and infrastructure. In contrast, regions such as North Kazakhstan and Pavlodar need to catch up, primarily due to harsher environmental conditions and lower investment levels. These differences point to the need for a targeted approach aimed at supporting less developed regions, as well as the dissemination of best practices from successful areas. The cartographic analysis visualizes these imbalances. The southern regions are highlighted as zones of high productivity, while the northern and eastern regions are shown as risk zones that require priority attention and resources. This research underscores the need for adaptive strategies to address regional inequalities, aiming to boost agricultural productivity and foster sustainable growth across Kazakhstan.

Authors: Khraiwish Ahmad , Alsharif Ahmad H.
Published: December 2024

Social media marketing employs channels like Twitter, Facebook, Instagram, and YouTube for purposes such as advertising, customer interaction, sales, and fostering connections with the target audience. A notable gap in prior research within the Scopus database prompted this investigation, employing a bibliometric analysis focused on “(social media marketing OR social media strategy OR social media management OR social media platforms OR social media trends or social media contest OR social media analytics).” Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework, we scrutinized relevant articles on Scopus from 2013 to November 2023, revealing insights from 1,198 articles. The review findings demonstrate that the number of articles devoted to the study of social media and social media marketing has increased exponentially in recent years. More importantly, the research identifies some of the most influential studies in this area. The paper discusses trends and highlights the challenges related to social media platforms and marketing. To the authors’ knowledge, this represents the first study to review the literature from leading journals on social media platforms in marketing using bibliometric techniques. Furthermore, lays the foundation for future research, guiding scholars to less-explored areas and fostering potential collaborations, thereby enhancing the depth of understanding in this domain.
The Multidimensional Nature of CSR: The Role of the CEO Socio-Demographic Profile
Authors: Bouzguenda Mariem , Jarboui Anis
Published: December 2024

It is important to find out why corporations commit to socially responsible activities. Prior research have predominantly applied a uniform perception of corporate social responsibility CSR without paying particular attention to separate CSR activities. This outlook is surprising because firms meet social responsibility expectations through a unique CSR in spite of the stakeholder divergence. For addressing the limitation of these perspectives, this study develops the divergent dimensions of CSR (environment, governance and social). Afterwards, we look into the interdependencies between the different socio-demographic factors specific to the CEO (age, tenure; gender, and education level), accounting for the divergence in the CSR dimensions. Based on a sample of companies listed on the STOXX 600 index throughout the period ranging from 2018 to 2022, the results confirm that age, tenure and education level of the CEO are positively affect the CSR in governance dimension and social dimension. Nevertheless, the gender variable is negatively correlated with their dimensions.
Re-investigation of Financial Development on Income Inequality: An Empirical Analysis for G-20 Emerging Economies
Authors: Ümit Asiye Öznur , Eyübuğlu Sinem
Published: December 2024

This research examines effects of financial development, economic growth, government expenditures, urbanization, and trade openness on income inequality in the leading emerging economies of the G-20 (Argentina, Brazil, China, India, Indonesia, Mexico, Russia, and Turkiye) for the period from 1989 to 2021. The findings confirm the existence of a cointegration nexus among the variables over the long-term. According to the common correlated effects mean group estimator, financial development has negative effects on income inequality in the panel. Factors such as government expenditures and trade openness demonstrate positive effects on income inequality. In the country-specific effects, we find that the impact of financial development on income inequality is negative and statistically significant in Argentina, India, and Russia. The influence of economic growth on income inequality is positive and significant in Indonesia, Mexico, and Turkiye. Government expenditures on income inequality appear to be positive in Argentina, Indonesia, and Mexico. Finally, trade openness demonstrates a positive and significant effect in India, Indonesia, Mexico, and Turkiye. Among the reasons for the differences in test results across countries are variations in their political structures, particularly the high inflation and macroeconomic instability in Turkey, the presence of the informal economy and corruption in Brazil, Indonesia, Turkey, and China, as well as regional inequalities. In this context, based on the overall panel test results, it is recommended that policymakers increase financial inclusion, reduce regional disparities, reduce corruption, increase social assistance, and balanced trade policy to enhance the impact of financial development on income distribution.
Income-Based Economic Determinants of Life Expectancy in Four Groups of Countries Classified by their Levels of Income
Authors: Abdulrahman Ismael , Chawsheen Sarah Ahmed
Published: December 2024

This study seeks to determine the role of per capita value added in the main sectors of; agriculture, industry, services, plus per capita GDP, on life expectancy at birth in the four groups of countries classified internationally by; high income, upper middle income, lower middle income, and low-income countries, during the period 1990-2022. Panel data analysis adopted for each group countries, where CS-ARDL approach is used to measure the effect of the independent variables (sector’s value-added per capita income) on the dependent variable (life expectancy at birth). The findings indicate that the per capita values provided by the sectors of industry and services are important factors in increasing life expectancy in high-income countries. Whereas, increases in per capita GDP would significantly extend life expectancy in countries ranging from upper-middle to lower-middle and low-incomes.
The Determinants of Firm Value: A Panel Data Approach on the S&P 500 Companies
Authors: Vintilă Alexandra Ioana
Published: December 2024

Over the last two decades, the US companies have faced a series of challenges caused by the two of the most significant events, namely the global financial crisis and the Covid-19 pandemic crisis. To analyze the influence of these crises along with other factors on the firm value represented by Tobin’s Q, there were estimated unbalanced panel data multiple regression models, with cross-section fixed effects, with cross-section and period fixed effects, with cross-section random effects, and with cross-section random effects with period fixed effects, using a sample of 442 non-financial companies included in the Standard & Poor’s 500 index, over a period of 20 years, from 2004 to 2023. The independent variables are divided into three categories, namely financial indicators, corporate governance variables, and dummy variables that indicate the crisis periods. The results showed that the financial leverage, asset tangibility, liquidity, firm size, the number of meetings attended by the board members annually, the proportion of the independent members on the board and the Covid-19 pandemic crisis had a positive effect on the company value, while the firm age, CEO duality, the number of the members on the board, the proportion of the females on the board and the global financial crisis exerted a negative impact on the firm value. To better differentiate the determinants of the firm value in the context of the two major events that occurred during the analyzed period, there were estimated other empirical models using interaction variables between each dummy variable showing the crisis and the other factorial variables.

This study uses geospatial techniques to detect changes in land surface temperature and cooling efficiency of green space in Phase One of the Federal Capital City, Abuja, Nigeria. Administrative boundaries shape file of 2023, Landsat imageries 4TM, 7ETM, 8OLI and 9TIRS and Thermal Near-infrared (7ETM, 8OLI and 9TIRS) were acquired from USGS Earth Explorer. The analyses of imageries were done within the ArcGIS 10.8 environment. In 1992 and 2002 green spaces covered the largest land area followed by built-up areas. In 2012 and 2022 built-up areas claimed the largest coverage area. From 1992 to 2002, the built-up area experienced the most significant change, showing an increase of 2.85 km2. During the same period, there was a loss in green space amounting to -2.13 km2, while the bare surface increased by 2.27 km2, from 2002 and 2012, the bare surface exhibited the most substantial change, experiencing an increase of 8.97 km2, while the built-up area also increased by 6.75 km2. Conversely, there was a significant decrease in green spaces, amounting to -18.72 km2 during the same period. From 2012 to 2022, the built-up area experienced the most substantial change, showing a 9.93 km2 increase. In contrast, bare surfaces decreased by -8.43 km2, and green spaces also decreased by -1.52 km2. From 1992 to 2002, an area with excellent cooling efficiency increased by 5.7 km2, an area with good cooling efficiency increased by 1.81 km2, and an area with normal cooling efficiency increased by an infinitesimal area of 0.37 km2. There was a decrease in an area with a bad cooling efficiency of -1.97 km2, area with a worse cooling efficiency was reduced by -5.91 km2. From 2002 to 2012, an area with excellent cooling efficiency decreased to -5.59km2, an area with good cooling efficiency decreased to -0.85km2, an area with normal cooling efficiency increased to an infinitesimal area of 0.82km2 and there was an increase in area with bad cooling efficiency with 1.55km2, an area with worse cooling efficiency increased with 4.07km2. From 2012 to 2022, an area with excellent cooling efficiency decreased by -1.22 km2, an area with good cooling efficiency decreased by -1.03 km2, and an area with normal cooling efficiency increased with a minute area of 0.73 km2 (1.187%). There was also an increase in area with a bad cooling efficiency of 0.82 km2, and worse cooling efficiency increased with 0.7 km2.

This study investigated the impact of materialistic Instagram reels on psychological distress, self-esteem, and life satisfaction. A cross-sectional correlational study was conducted on materialistic Instagram reels, psychological distress, self-esteem, and life satisfaction. A sample size of 300 participants was selected through convenience sampling. The scales utilised during the study were the Materialism Scale developed by Richins and Dawson (1992), the Self-Esteem Scale developed by Rosenberg (1965) to measure self-esteem, the Psychological Distress Scale developed by Kessler (1992) to measure psychological distress, and the Satisfaction with Life Scale developed by Diener, et al., (1985) to measure life satisfaction. The data collection methods used were physical and online surveys and the gathered data was analysed statistically. The result showed a significant impact of materialistic Instagram reels on psychological distress and self-esteem. However, no significant impact of materialistic Instagram reels on life satisfaction was found. The study recommends addressing materialistic values alongside mental well-being to enhance life satisfaction and psychological health.

Bu çalışmanın amacı modern liderlik yaklaşımlarının, bilgi çağında faaliyet gösteren spor örgütleri üzerindeki etkilerini literatürde yer alan bilgiler aracılığıyla ortaya koymaktır. Liderlik kavramı, içinde bulunduğumuz yüzyılda meydana gelen toplumsal, ekonomik ve teknolojik gelişmeler ile birlikte önemli bir dönüşüm geçirmektedir. Özellikle sanayi toplumunun yerini bilgi odaklı bir toplumun aldığı günümüzde geleneksel liderlik yaklaşımları, örgütlerin ve toplumların mevcut ihtiyaçlarına tam anlamıyla cevap verememektedir. Dolayısıyla teknolojide meydana gelen hızlı gelişmeler ve toplumsal değişimler, liderlerin stratejik kararlar alırken bilgiyi etkin bir şekilde yönetmesini zorunlu kılmaktadır. Nitekim bu toplumsal dönüşüm süreci, modern toplumların önemli bir parçası olan spor örgütlerinin de yeni gereklilikler doğrultusunda önemli yapısal dönüşümler gerçekleştirmesine neden olmaktadır. Bu alanda yapılan araştırmalar, geleneksel liderlik yaklaşımlarının giderek karmaşık bir yapıya bürünen spor yönetimi alanında yetersiz kaldığını vurgulamaktadır. Bu nedenle bilgi çağında faaliyet gösteren spor örgütlerinin, güncel ihtiyaçlara cevap verebilecek etkili adaptasyon sistemlerine sahip ve inovasyonu destekleyen liderlik yaklaşımlarına ihtiyaç duyduğu ifade edilebilir. Derleme deseninin kullanıldığı bu çalışmada, veri toplama aracı olarak literatüre dayalı detaylı kaynak taraması metodu kullanılmıştır. Sonuç olarak, modern liderlik yaklaşımlarının, bilgi çağında spor örgütlerinin performansı ve sürdürülebilirliği üzerinde pek çok olumlu etki yaratabileceği görülmektedir.

Patojen mikroorganizmaların çoklu antibiyotik direnci geliştirmesi tedavi sürelerinin uzaması, ölüm oranlarının artması ve ekonomik kayıplara neden olmaktadır. Bu çalışmada, geleneksel antibiyotiklere karşı gelişen direnç nedeniyle alternatif antibakteriyel ajanlar geliştirilmesi ihtiyacı ele alınmıştır. Laurus nobilis yapraklarından elde edilen ekstraktların Escherichia coli ve Proteus mirabilis patojenlerine karşı antibakteriyel etkileri araştırılmıştır. Araştırmada, L. nobilis yaprak ekstraktlarının, özellikle yüksek dozlarda (50 µL), her iki patojen üzerinde de inhibisyon sağladığı belirlenmiştir. Ayrıca, moleküler kenetlenme yöntemi ile defne yaprağının uçucu yağ bileşenlerinin bakteri hücre duvarı oluşumunu kontrol eden proteinlerle etkileşim potansiyeli incelenmiştir. Sonuçlar, L. nobilis ekstraktlarının, özellikle çoklu antibiyotik direnci geliştiren patojenlere karşı, etkili bir alternatif olabileceğini göstermektedir.
