Decreasing the energy demand in public buildings using nature-based solutions: case studies from Novi Sad (Republic of Serbia) and Osijek (Republic of Croatia)

BackgroundNature-based solutions (NBS) in urban areas offer an opportunity to improve environmental conditions and to reduce CO2 emissions towards establishing climate-neutral cities in the next few decades. Furthermore, the implementation of NBSs—vertical or horizontal green infrastructures on public facilities—could in particular improve both climate, including outdoor thermal conditions on a micro-scale (especially during the summer season) and the energy demand of buildings as well as save heating energy during the winter period.ResultsOn both selected buildings, extensive green roofs were implemented as an NBS intervention. The analysed data were obtained using the monitoring systems (from 2019 to 2022) installed on two public buildings in Novi Sad (Republic of Serbia) and Osijek (Republic of Croatia), with a focus on climate/bioclimate characteristics and thermal transmission capacities. Four automatic weather stations (AWS) were used for microclimate monitoring, along with the heat flow meter (HFM) method, to measure the alterations in the thermal transmittance (U value) of a flat concrete roof before and after energy refurbishment and the installation of a green roof. The outcomes of this study show that the air temperatures (Ta) and globe temperatures (Tg) near the green roof are lower by 0–3 °C for Ta and by 0–16.5 °C for Tg than the values captured by the AWSs at other locations. An even more interesting fact is that the green roof has a constant cooling potential during tropical nights, and based upon this research, the cooling value is around 2 °C for Tg (the Ta value is not distinct). The thermal transmittance results show that more savings can be achieved by applying a green roof with an 8 cm thick substrate: U values decreased by 50–69%, as measured by two different heat flux sensors.ConclusionsNature-based solutions, such as the implementation of an extensive green roof, have positive effects on diverse aspects of urban environments and building energy savings, which are particularly evident in extreme seasons, both summer and winter. Applying the proposed monitoring and assessment system could help local communities in their efforts to reduce carbon-based emissions. This paper provides a good example of the implementation of NBSs on a local- and a micro-scale.

Interview as a research method in teaching: a case study

Although the application of modern technologies in the education system of Serbia shows signs of progress in the last few years, it is still not at a satisfactory level. Hence the demands for improvement of learning methods and means are imposed. In order to determine to what extent each form of work is represented in the teaching of informatics and computer science, we conducted an interview with teachers of informatics and computer science in elementary schools in the territory of the cities of Belgrade and Novi Sad. The sample includes 19 teachers. The teachers answered 23 questions, which we divided into five groups. The research was conducted in two phases in May 2022 and June 2023. Contemporary conditions require a change in the content and methods of organizing the education process, and the transformation of the traditional school into a research unit ready to accept innovations.

Vladika bački Irinej i odnosi između Srpske pravoslavne crkve i države (1944–1955)

The aim of this paper is to examine the relationship between the Serbian Orthodox Church and the Yugoslav state in Vojvodina and Bačka in the context of the new communist regime’s treatment of the bishop of Bačka, Irinej Ćirić, from the time of the bishop’s liberation (1944) until his death (1955). Irinej was imprisoned under house arrest for 17 months shortly aft er the partisans captured Novi Sad due to his connections to the Hungarian occupation regime. Upon his release, he was attacked and beaten by a group of locals in Odžaci in 1946. This event, known as the ”Odžaci Affair”, was one of the contentious issues that burdened relations between the church and the state for a long time. The research also looks at how the Diocese of Bačka operated from 1944 to 1955, the attitudes of the clergy - who were closely monitored by the secret service and under pressure from the new authorities - and Irinej and his associates’ positions on certain political and ecclesiastical issues. It also examines at how these issues were resolved through mutual adaptation and a shift in the state’s attitude toward the church.

Geological and Geotechnical Aspects of the Most Significant Deep Landslides in the Danube Area on the Territory of Vojvodina

The largest and the deepest landslides in Serbia occurred on the right valley side of the Danube. General conclusions about landslides along the Danube were obtained on the basis of their comprehensive, detailed investigations: the Sloboda bridge in Novi Sad, the Beška bridge, the large settlement of Bocke, and the high-speed railway viaduct in Čortanovci. These areas are actually large, unstable slopes with deep and shallow landslides. Deep landslides consist of several sliding blocks with 20–40 m in depth. All these landslides were formed in clays and sands of the Pliocene age in the decayed crust of these sediments. The general conclusions about landslides presented in this paper will be of great use for the construction of new facilities in the entire unstable area along the Danube, which is about 100 km in length.

THE SIGNIFICANCE OF THE LAW ON AMICABLE RESOLUTION OF LABOR DISPUTES AND THE REVIEW OF THE PRACTICE THUS FAR

During the work process, numerous instances of dispute regarding the positions of the employees, or the interpersonal relations between them or between them and their employer may arise. In addition to the traditional judicial method of labor dispute resolution, it is necessary to develop independent and impartial negotiation mechanisms between the parties in the area of individual and collective labor disputes. In Serbia, these are certainly the arbitration settlement of individual and collective labor disputes, and conciliation as a method of resolving collective labor disputes within and through the Republic Agency for Peaceful Settlement of Labor Disputes. There are many benefits to peaceful labor dispute settlement. The goal of supplementary procedures, i.e. procedures for peaceful labor dispute resolution, is to relieve the traditional judicial approach and direct it to the procedures where a judicial settlement of the dispute is truly necessary. Besides the concept, advantages and characteristics of the amicable labor dispute settlement procedures, certain types of these procedures such as mediation, conciliation and arbitration are also analyzed in the theoretical section of this paper, as well as the most important provisions of the Employment Act and the Law on Amicable Resolution of Labor Disputes. In the research section of this paper, the practice of the Republic Agency for Peaceful Settlement of Labor Disputes in the procedures of amicable labor dispute settlement, both for the territory of the Republic of Serbia and the territory of the City of Novi Sad, is analyzed. The primary research data source was the official data of the Republic Agency for Peaceful Settlement of Labor Disputes. The paper is methodologically based on a theoretical analysis of relevant contemporary theoretical views, a normative analysis of legislative sources, and a quantitative analysis of statistical indicators in the domain of the research subject.

Advancing Social and Economic Sustainability in Urban Areas: A Methodology for Determining Architectural Programs of Shopping Centers

The surge in shopping center construction within urban areas, especially without a strategic plan, has been particularly notable in Eastern Balkan cities during the 21st century. This tendency may lead to decreased economic activity and noticeable shifts in social and cultural dynamics. The primary objective of this study is to introduce and apply the Methodology for Determining Architectural Programs (MDAP), a mathematical model designed to optimize the planning process of shopping centers. Focused on spatial disposition and internal program distribution, MDAP extends the foundational Huff model by incorporating relevant economic parameters—consumers’ purchasing power and potential investors’ costs. Examining the city of Novi Sad, Republic of Serbia, the results indicate the consistency of the MDAP’s results compared to the application of the basic Huff model. This approach could contribute to a more balanced economic distribution within cities, promoting social and cultural relations while offering investors a relevant feasibility study and preserving shopping centers’ profitability. This study underscores the significance of considering social sustainability in urban planning, emphasizing how strategic urban retail development can positively impact social dynamics alongside economic viability by maximizing the potential utilization of existing retail spaces. However, potential limitations include unforeseen social, economic, and political factors influencing shopping center location decisions, posing challenges in real-world applications relying on complex social relations.

Physical activity and mental health of medical students.

Medical students usually do not meet the recommendations on the minimum level of physical activity, despite knowing the impact that physical activity has on the prevention and treatment of various diseases. Medical students are considered to be insufficiently physically active. The aim of this study is to determine the prevalence of physically active fifth-year medical students at five universities in Serbia, as well as to identify factors associated with insufficient physical activity of students. A cross-sectional study was performed in the population of fifth-year medical students from five different universities in Serbia. The research instrument was a questionnaire specially designed based on similar research. Descriptive and analytical statistics methods were used in statistical analysis. The study included a total of 573 fifth-year medical students from five universities in Serbia: 311 (54.3%) Belgrade; 86 (15.0%) Kragujevac; 58 (10.1%) Nis; 66 (11.5%) Kosovska Mitrovica; 52 (9.1%) Novi Sad. Insufficient physical activity was statistically significantly associated with studying at the University of Kosovska Mitrovica (OR = 3.98, 95% CI: 1.83-8.57). There was a statistically significant difference in the frequency of anti-anxiety medications use in the last 12 months between students with sufficient and insufficient physical activity (p = 0.040) as well as in the average number of cigarettes smoked per day between students with sufficient and those with insufficient physical activity (2.82 ± 6.35 vs. 4.50 ± 8.29, p = 0.043). There was also a statistically significant difference in the average score on the Beck's depression scale between students with sufficient and students with insufficient physical activity (6.51 ± 6.59 vs. 10.03 ± 9.37, p < 0.001) and in the average score on Zung's anxiety scale (34.86 ± 8.18 vs. 38.07 ± 8.71, p = 0.003). A high percentage of medical faculty students (86.6%) are physically active. Differences in the level of physical activity were observed between students of these five universities as well as between students with different levels of physical activity.

Temperature-based Evapotranspiration in the WSVI Drought Index Implementation

Drought is a natural hazard that affects environmental and socio-economic development. In this study, the Water Surplus Variability Index (WSVI), which is based on both precipitation and Penman-Monteith (PM) evapotranspiration (ET) estimates, was used to quantify drought. The application of the WSVI is not possible in some locations because of the missing data for estimating ET. The key objectives of this research were to 1. compare the different temperature-based WSVIs for the 1-, 3-, 6- and 12-month timescales with the original PM-based WSVI; 2. improve the WSVI by replacing the full-set PM equation with the corresponding temperature-based ET equation, such as Hargreaves, adjusted Hargreaves, Thornthwaite, modified Thornthwaite or temperature-based PM; and 3. compare the best temperature-based WSVI with the Standardized Precipitation Index (SPI). The set of meteorological data was obtained from several stations from Pannonian Basin (Budapest, Debrecen, Novi Sad and Sombor). According to statistical indicators, the Hargreaves-based WSVI (WSVIH) was ranked first or second for each time period at all locations. The WSVIH was additionally tested using the SPI for each location and each timescale. The obtained results indicated the capability of the WSVIH to quantify drought frequency, duration and severity identified by the SPI. Finally, the WSVI can be recommended using the Hargreaves equation instead of the full-set PM equation in future WSVI implementations in the Pannonian Basin.

Effects and Consequences of Authoritarian Urbanism: Large-Scale Waterfront Redevelopments in Belgrade, Zagreb, and Novi Sad

This article highlights the (post) transitioning urban context as an emerging market for powerful international real-estate development companies, supported by an authoritarian planning trend aiming to secure foreign investments. Such a pattern is particularly noticeable in the implementation of the large-scale redevelopment project Belgrade Waterfront in the Serbian capital city, causing many controversies due to state-led regulatory interventions, investor-friendly decision-making, and a general lack of transparency. Although proactive but fragile civil society organizations in Serbia failed to influence the implementation dynamics of this megaproject, it inspired contestation by professional and civic organizations elsewhere, which finally led to significant disputes over similar developments. This study highlights similarities of this project to the initiatives emerging in other cities of the ex-Yugoslav countries: Zagreb Manhattan, announced to settle on the waterfronts of the Croatian capital, and more recently the Novi Sad Waterfront in the second largest Serbian city. The article concludes with a general overview of the effects and consequences characterizing the emerging trend in the production of space and highlights the rising role of the civil sector in more inclusive and democratic urban planning in ex-Yugoslav cities.

Evaluating the influence of dental aesthetics on psychosocial well-being and self-esteem among students of the University of Novi Sad, Serbia: a cross-sectional study

BackgroundA person’s smile has been identified as one of the first observed facial characteristics. Even minor deviations from societal beauty standards, especially among younger individuals, can have a negative effect on their self-esteem. The aim of this research is to evaluate the self-perceived psychosocial impact of dental aesthetics and self-esteem among respondents and their association, as well as to determine the main factors contributing to dissatisfaction with dental appearance.MethodsThis research was conducted as a cross-sectional study that surveyed students of the University of Novi Sad. Other Universities and private faculties were excluded from participation. Data collection used standardized questionnaires measuring the Psychosocial Impact of Dental Aesthetics (PIDAQ) and the Rosenberg Self-Esteem Scale (RSES). Questionnaire (an online GoogleForms) was sent to the students via official Facebook groups of the faculties, student’s e-mails and Instagram profiles. Data analysis included descriptive statistics, Students T-test, ANOVA, multiple linear regression analysis and Spearman coefficient. To test internal consistency, Cronbach’s alpha(α) was calculated for the questionnaire as a whole (0,761) and each used questionnaire (PIDAQ – 0.766; RSES – 0.765). Cronbach’s alpha(α) was also calculated for each domain from PIDAQ (DSC-0.946; SI-0.882; PI–0.953; AC-0.916).ResultsThe study involved 410 participants, predominantly female (80%), aged between 21 and 23 (45.4%), primarily in ther first academic year (21.5%), and with a grade point average between 8.01 and 9.00 (42.4%). Data analysis has shown a statistically significant difference in the total PIDAQ score and SI subdomain in relation to the academic year (total PIDAQ p = 0.025; SI p = 0.000). In terms of self-esteem, results of multiple linear regression analysis showed that the academic year (95%CI: 0.410–1.837; p = 0.002) and the average point grade (95%CI: -0.025-1.600; p = 0.047) were significant predictors of greater self-esteem. The Spearman coefficient value (r=-0.316, p < 0.001) confirmed a statistically significant negative correlation between PIDAQ and self-esteem. Only 34% of respondents expressed satisfaction with their teeth. Dissatisfaction about the smile was primarily attributed to the arrangement and positioning of their teeth (32.2%). Financial constraints were identified as the main barrier for seeking interventions to improve smile satisfaction (39.5%).ConclusionStudents experiencing a greater psychosocial impact of dental aesthetics tended to exhibit lower self-esteem.

Significance and perspectives for development of commodity exchange trade in agricultural products

Exchanges are intermediaries in the trade of commodities, financial instruments that have commodities in their base or credit instruments that are secured by commodities. Commodity exchanges have gained in importance in recent decades. Commodity exchanges have evolved from the place where the physical purchase and sale of goods takes place to trade in commodity derivatives where standardized contracts−futures and options−are traded. The role of commodity exchanges in the development of the agribusiness sector has changed significantly from the initial stage of development when in the beginning the main role was to ensure efficient and transparent exchange of commodities, until the early 1970s when instruments were developed to enable risk management in the agribusiness sector. The largest volume of tradе on modern commodity exchanges is realized in standardized derivative contracts. Financial derivatives are one of the most successful financial innovations, with the volume of turnover increasing significantly. Within this chapter, special attention is paid to the analysis of the situation in the field of commodity exchange trading in the Western Balkan region. According to the results of the analysis, developed agricultural commodity exchange trade is not available to the farmers in these countries, nor are business risk management instruments available to participants in countries with developed commodity exchange systems. Analyses have shown that the sole commodity exchange with a significant volume of trade in the countries of the Western Balkans is the Novi Sad commodity exchange, trading on the spot and non‒standardized term market. In terms of the directions of development of regional commodity trade, the experience so far shows that high trading volume is a paramount for well‒developed commodity exchange. Therefore, the path to the development of commodity exchange trading is the establishment of a regional commodity exchange that would be a place of trade for all of the Western Balkan’s countries. By establishing a regional commodity exchange, participants in the agricultural sector would have the opportunity to securely and transparently trade and manage the price risk that have a pronounced volatility in recent years.

Impact of urban outdoor thermal conditions on selected hospital admissions in Novi Sad, Serbia

Climate change has been recognized as an important issue in public health, with particular concerns being raised about the effects of heat and cold extremes on health, and about seasonal changes over the year and their associations with increased mortality and hospitalizations. This paper explored the relationship between physiological equivalent temperature (PET) and cardiovascular and respiratory hospital admissions in Novi Sad (Serbia) with the aim of assessing the impact of urban outdoor thermal conditions on health. Analysis was performed using daily data on cardiovascular and respiratory hospital admissions by gender covering the period from January 1, 2016 to December 31, 2017. For the same period, PET was calculated using data from two urban meteorological network stations. The association between PET and hospital admissions was examined using a generalized additive model (GAM) combined with a distributed lag non-linearmodel (DLNM). The study found a non-linear relationship between PET and cardiovascular and respiratory hospital admissions, with a larger impact during the cold period of the year. The findings also indicated that under conditions of high PET, the cumulative RR increased for cardiovascular admissions (for males) and respiratory admissions (for females). People with pre-existing respiratory diseases were found to be more vulnerable under conditions of extremely low and moderately low PET, with a greater effect at lag 0–14 days. By contrast, for people with cardiovascular diseases, low PET was linked to a decrease in hospital admissions, with the risk being lowest at lag 0 and 0–3 days.

Differences in Trunk Muscle Strength (Lateral Flexor Group) between Male and Female Athletes

The strength of the lateral flexor muscles in the trunk is necessary for maintaining stability in the rib cage, spinal column, and preventing a higher number of injuries, while also enhancing overall trunk muscle strength. This study, conducted in a transversal manner, aimed to identify gender-based differences in the strength of trunk lateral flexor muscles among university athletes in the younger senior age group. The study involved 46 athletes from the University of Novi Sad, comprising 25 male participants (height =181.27±6.28 cm; weight =78.31±12.14 kg; BMI =23.78±3.13 kg/m2; mean age =23.75±0.30) and 21 female participants (height =168.19±5.48 cm; weight = 3.72±5.94 kg; BMI =22.53±7.78 kg/m2; mean age =23.68±0.22). The results of the independent t-test revealed no statistically significant differences between the two gender groups based on dimorphic characteristics (p&gt;0.05) in the assessment of trunk lateral flexor muscle strength. It is essential to consider other aspects of the locomotor system specific to each sport and discipline to effectively prevent injuries during training and decrease the overall injury rate.

Contribution to the Optimization of Methods for Vigor Seed Evaluation of Camelina sativa (L.) Crantz

Camelina, a traditional oil-producing plant, has gained global interest due to the high-quality oil found in its seeds. It has numerous applications, including human dietary consumption, aviation biofuel, and biodiesel production. Seed quality testing is crucial for identifying suitable seed batches for market sale. Currently, vigor tests have been established for a limited selection of commercially cultivated plant species, including camelina. This study aims to assess seed vigor and contribute to the development and validation of methods/tests for reliable vigor assessment. The experiment used two camelina genotypes developed at the Institute of Field and Vegetables Crops in Novi Sad, Serbia. The findings revealed a noteworthy reduction in germination percentages for both genotypes across all the conducted tests, as compared to the conventional laboratory germination. Simultaneously, there was a notable increase in abnormal seedlings. However, no statistically significant differences in the values of growth parameters were observed among the applied tests. In summary, the reduced seed vigor values indicate potential issues with this trait, despite generally sound germination. Additionally, the preliminary findings and methodology developed for testing the camelina seed vigor highlighted the need for optimization when applying these tests to other species to ensure their reliability and applicability.

The influence of gastronomic identity factors on food tourism development in the Republic of Serbia and Bosnia and Herzegovina.

The gastronomic identity of an area is the key factor in tourism development, attracting numerous tourists and generating significant income. Numerous economic actors participate in its use and proper placement, and their perception of the gastronomic potential significantly affects its distribution and use in tourism. The main aim of this study is to investigate the factors of gastronomic identity that influence the development of tourism, observed at two tourist destinations in Southeast Europe [the Republic of Serbia (RS) the city of Novi Sad with Fruška Gora Mountain, n = 305 and Bosnia and Herzegovina (BIH) the city of Sarajevo with Jahorina Mountain, n = 301]. In order to define the factors that are relevant to food tourism development, a custom-made GastroIdentity scale was created. A survey was conducted among employees in the hospitality and tourism industry as well as employees in educational institutions in the field of hospitality and tourism. The research results show that employees from the RS area acknowledge the importance of organizing gastronomic events where local products are presented and that they understand that dishes and beverages with unique and recognizable tastes can characterize their area. Employees from the BIH area pointed out that the nutritional quality of their local agricultural and gastronomic products represents an advantage when compared to mass-produced ones and that the local gastronomic culture and tradition are authentic representatives of the culture of the region. The GastroIdentity scale proved to be dependable, highlighting gastronomic culture and tradition as extremely crucial factors in tourism, using the input provided by the employees from the investigated areas. Noteworthy results were also recorded regarding the need for incentives for food tourism development in the investigated regions.

Effects of urban vegetation on PM mitigation: The case of a street in Novi Sad, Serbia

Experiencing rapid development and growth, cities worldwide face a surge in air pollution, primarily driven by increased concentrations of particulate matter (PM) originating from various anthropogenic sources, such as traffic, household fuel combustion, and industrial and construction activities. Urban green spaces can naturally filter PM through physicochemical processes, serving as effective urban planning instruments for improvement of the air quality. Focusing on a street in Novi Sad, the second-largest city in Serbia, this study investigates the efficiency of vegetation in mitigating air pollution, specifically PM10 emissions from traffic and construction activities. Utilizing contemporary monitoring and modeling techniques for measuring and predicting PM10 concentrations, the focus of this research is to evaluate the efficacy of vegetation in affecting and minimizing detected PM concentrations. The results indicate a significant reduction in the monitored PM10 concentrations behind the green barrier compared to the modeled concentrations near the pollution source (on the road) for both traffic and construction-related emissions. The paper highlights the capacity of green elements to act as natural air pollution mitigators and advocates for better integration of strategic environmental management into urban planning to foster the development of healthier and more sustainable cities, providing recommendations to facilitate this objective.

Sindrom sagorijevanja zdravstvenih radnika zaposlenih u jedinicama intenzivnog liječenja - iskustva u tri jedinice intenzivnog lečenja iz tri velika zdravstvena centra sa Jugoistočnog Balkana - sindrom sagorijevanja zdravstvenih radnika jedinica intenzivnog liječenja Jugoistočnog Balkana

Summary Introduction: Burnout syndrome at work is a response to chronic emotional and interpersonal stressors associated with the workplace, and occurs in workers without previous psychopathological illnesses or organic diseases. Aim: The aim of the research was to examine the prevalence of stress and burnout syndrome, among physicians and nurses working in the intensive care units (MICU) of 3 regional centers (Banja Luka, Novi Sad and Ljubljana), and to determine the differences between the centers and the causes of these differences. Methods: It is a cross-sectional study conducted during August and September 2020 (at the peak of the COVID-19 pandemic) by surveying healthcare workers (doctors and nurses/technicians) from three intensive care units of the former Yugoslavia. The participantsfulfilled the Questionnaire for self-assessment of stress levels and the Maslach burnout inventory, which were supplemented with sociodemographic parameters. The obtained data were statistically processed using the SPSS 21 program. Results: 91 participantsfrom all 3 regional centers were included in th study. A statistically significant difference was found in terms of age, degree of professional education, length of service, gender, marital and parental status, where respondents from Ljubljana show the greatest deviations comparedto subjects from the other two centers. The sociodemographic characteristics of the respondents only showed that gender had a statistically significant influence on the degree of personal achievement. Conclusion: The attributes of healthcare professionals who work in MICUs with the same level of life support (level III) may be influenced by the development level and length of tradition of intensive care units. Additionally, factors such as legislation and other external and internal elements unique to each organizational unit can also play a role.

The effects of pre-sowing treatments with aqueous allelopathic plant extracts on the germination parameters of aged soybean seeds

The aim of the paper was to examine the allelopathic influence of aqueous extracts of herbs and medicinal plants on the quality parameters of aged soybean seeds. The research was carried out at the Institute of Field and Vegetable Crops in Novi Sad on aged seeds of two soybean varieties, NS simba and NS viseris. The seeds were aged for 20 months. In order to determine the allelopathic effect, the seeds were primed in aqueous plant extracts: geranium (Geranium sinense), dill (Anethum graveolens), andy everlasting (Helichrysum arenarium), creeping thyme (Thymus serpyllum), celery (Apium graveolens), oregano (Origanum vulgare), basil (Ocimum basilicum), lemon balm (Melissa officinalis), rosemary (Rosmarinus officinalis), wormwood (Artemisia absinthium), peppermint (Mentha x piperita), sage (Salvia officinalis), and lavender (Lavandula angustifolia). The results show that it is not possible to talk about the universal application of a particular aqueous extract, because the effect of the allochemicals was significantly influenced by the variety. In the variety NS viseris, all aqueous extracts except Melissa officinalis, significantly reduced GE, GP, and VI. The most negative effect was achieved with the use of Apium graveolens, Thymus serpyllum, and Ocimum basilicum. Apium graveolens and Thymus serpyllum also had the greatest impact on quality reduction in the NS simba variety. However, in the NS simba variety, a significant increase in seed quality was achieved in addition to the reduction. The use of the aqueous extract of Salvia officinalis increased GE and GP by 13.7%, and VI by 10.21%. A positive effect was achieved with the use of Melissa officinalis. All aqueous extracts had a significant effect on T50 in both varieties, even the aqueous extracts that had a negative effect on GE and GP.
