World Climate Declaration: Exhaled Carbon Dioxide Promotes Plant Development
Authors: Kutschera Ulrich , Ehnes Ingo
Published: October 2023

The British Naturalist Alfred Russel Wallace (1823–1913), who was born 200 years ago, argued in a popular book of 1903 that carbon dioxide (CO2) is enriched in exhaled air of humans, and bad for our health, but essential to plant development. With reference to the 2023 World Climate Declaration, we document that exhaled CO2 drastically promotes the growth of a representative land pant. Using regenerated cuttings of Tradescantia geniculata, raised in moist soil, we show that, within 21 days of growth in a day-/night-cycle, CO2-enrichment (ca. 4 vol. % vs. 0.04 vol. % in the control) exerts the following effects: Average stem length is doubled, a three-fold enhancement in the number of branches occurs, and adventitious roots, plus flowers, develop. This CO2-fertilisation-experiment is discussed in the light of the “Global Greening”-phenomenon, documented as large increase in plant biomass since ca. 1850. We also address negative effects of further rising CO2-levels in the atmosphere on the global environment in the ongoing Anthropocene. Finally, we point out that A. R. Wallace was not only a theorizing explorer of nature, but also an expert in animal- and plant physiology.
Hybrid functional Pani/TiO2 nanocomposites for dyes degradation treatment
Authors:   ", Milošević Milica ,   Vinča” Institute of Nuclear Sciences - National Institute of the Republic of Serbia, University of Belgrade
Published: October 2023

A calling need for environmental protection is not abating and high demands have been set for the current topic that deals with applied technologies for removal of organic pollutants. The AOPs appear to be one of the most effective processes, where heterogeneous photocatalysis using efficient UV light-harvesting TiO2 nanocrystals has unquestionably become one of the most commonly used process for dyes degradation treatment. Limited photocatalytic efficiency of TiO2 under sunlight illumination was overcame by coupling with polyaniline (PANI) as notably investigated conductive polymer. Reducing the level of e-/h+ recombination in TiO2 and photosensitized properties of PANI was the basis for creation of new functional PANI/TiO2 nanocomposites. Such hybrid functional nanomaterials consisting of conductive polymers and dissimilar nanocrystals manifest the unique properties, usually not characteristic of independent components but their synergistic effect. Series of developed functional nanocomposites based on PANI and colloidal TiO2 nanoparticles (NPs) (TP), carbonized PANI and colloidal TiO2 NPs (TPC) and carbonized PANI and TiO2 nanotubes (NTs) (TTPC) by the efficient and harmless synthesis pathways are presented. Differently shaped TiO2 nanocrystals are carefully prepared via sol-gel and hydrothermal synthesis and the influence of their size and shape on the photocatalytic efficiency of hybrid nanocomposites was evaluated. The non-carbonized PANI/TiO2 nanocomposites were synthesized by the chemical oxidative polymerization of aniline with ammonium peroxydisulfate, in the presence of selected TiO2 nanocrystals, while the carbonized class was obtained in the subsequent carbonization process, following the polymerization, in an inert atmosphere at 650 °C. The morphology and structure of these nano-based photocatalysts was determined by TEM analysis and Raman spectroscopy. Functionality of nanocomposites was evaluated following the photocatalytic degradation processes of model compounds Methylene blue and Rhodamine B and enhanced degradation efficiencies in the used dyes were observed.
Auxiliary exhaust system under pressure for the discharge of gases from factory chimneys
Authors:   Best miron, Majur, Šabac, Stanišić Radovan
Published: October 2023

The subject of research work is solving the problem of reducing air pollution around factory chimneys, without affecting the flow of gases in the chimney itself. The proposed solution is in the flow of pressurized air that creates an "air tube" at the very top of the chimney, with the same diameter as the chimney, which can be seen as a physical extension of the chimney. Pressurized air should ensure the protection of the exiting gases from the impact of the wind and thereby increase the dispersion height of the gases in the atmosphere. In the first part, there is a definition of the problem and consideration of its solution. The second part describes the construction of the device in 2 variants. In the third part, a solution proposal for an average factory chimney is given. Input parameters for the calculation and selection of equipment are: height and diameter of the chimney, as well as wind speed, wind impact as the most influential factor on the output gases. A solution proposal with the characteristics of equipment, devices and other parts to be installed is also given.
Development of international standards for university-business collaboration
Authors:   University of Belgrade, Faculty of organizational sciences, Belgrade, Đurić Mladen
Published: October 2023

Collaboration between academic and business organizations has always been a topic that attracted the attention of both sides, but the mere absence of significant international or global standards that would regulate this area implies that its potential still hasn’t been sufficiently used. In the International Organization for Standardization (ISO), within one of the more active technical committees - ISO/TC 286 Collaborative business relationship management, relatively recently, in March 2022, a special working group was formed, with the aim to develop the first potentially global standard with the guidelines for cooperation between organizations that are part of the universities and all the others, commercial and non-commercial, that are external to the universities. The Republic of Serbia, i.e. its representatives - on behalf of the Institute for Standardization of Serbia, represents one of the first countries participating in this process, which is organizationally and administratively led by experts from China and the UK, delegated by the Chinese and British standardization bodies. This invited paper/lecture provides both overview of the current state and trends regarding university-business colaboration (UBC) standardization process, as well as the basic characteristics of the current, draft version of the document entitled "ISO 44006 Collaborative business relationship management — Guidelines for university-business collaboration". According to the current plans, this standard should be published in 2025 and should serve as a guide for universities, businesses, and other stakeholders in using the already existing 12 principles of collaborative business relationships to improve their capability in university-business collaboration.

Antinuclear antibodies (ANA), first discovered many decades ago in patients with systemic lupus erythematosus (SLE), still remain a diagnostic criterion for this disease. However, subsequent studies have shown that the range of diseases in which ANA are detected is extremely wide and includes not only systemic rheumatic diseases, but also other autoimmune diseases (AD), including autoimmune cytopenias, autoimmune liver diseases, gastrointestinal diseases, autoimmune pathology of the thyroid gland and other endocrine glands, autoimmune skin diseases etc. The low specificity of ANA determines their relatively low diagnostic value, which increases when taking into account the luminescence pattern, indicating the presence of certain autoABs. The presence of ANA in patients with AD has a certain prognostic significance since in a number of diseases it is associated with their clinical features and the nature of the process as well as the expected response to the treatment with various drugs. Due to the fact that various AD are often combined in patients, the detection of ANA may be a reason for expanding the examination aiming to diagnose them in a timely manner. See Part 2 at N.S.

An Emphasis Study on Residual Engineering Properties of Fly Ash Concrete Elevated Temperature
Authors: Zuhan Nurizaty
Published: October 2023

The paper examines the properties of fly ash as partial cement replacement in normal strength concrete at ambient and elevated temperature. The properties of fly ash class F was chemically investigated. Behaviour of concrete containing fly ash subjected to elevated temperature 200 ºC up to 600 ºC at temperature rate of 2.78 ºC/min is investigated mechanically and microstructurally. Physically, fly ash concrete changed colour to brown at 400 ºC and to whitish grey at 600 ºC, which is similar to normal concrete. At 600 ºC, the residual compressive strength of fly ash concrete was slightly higher than normal concrete with a strength reduction of 13.18% and 45.22%, respectively. At 400 ºC, fly ash concrete has better splitting tensile strength than normal concrete with strength reduction of 28.81% and 43.26%, respectively. Thus, the use of fly ash as cement replacement in fly ash concrete improves concrete performance after exposed to elevated temperatures. Based on Field Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive X-Ray (EDX), fly ash concrete performed better thermally proven by the formation of ettringite. In conclusion, the utilization of fly ash as a replacement for Ordinary Portland cement (OPC) at elevated temperatures is a good innovation for concrete performance.
GUI-Based Data Visualisation Tool for Option C IPMVP using Jupyter Notebook
Authors: Abdullah Ezmin
Published: October 2023

IPMVP is an acronym for International Performance Measurement and Verification Protocol, used for calculating energy savings by taking some external factors into account to give an equal base for a linear comparison between two periods. However, determining the significant independent variable for routine adjustment causes inconvenient repeated action of regression analysis modeling, which leads to the exhaustive calculation and human error risk. These exasperating actions led to the creation of this project, which aims to provide a user-friendly, insightful, and accurate energy-saving calculation program tool. Thus, the main objective of this project is to develop an energy-saving computational tool for option C IPMVP using web-based data analytic tools to improve efficiency and accuracy in each project. This paper used a web-based mathematical computation, Jupyter Notebook, to determine the significant independent variable for routine adjustment of the adjusted baseline. The program tool was validated using V-model software verification and validation methodology based on IEEE 1012 standards. The study can be concluded that the exhaustive calculation to determine the energy saving based on IPMVP standards can be significantly reduced with precision values at 50%, 80%, 90%, and 95% confidence levels using the proposed program which is equipped with insightful graphs and a user-friendly interface.
Dynamic Behaviour of Flow Through Three Circular Cylinders in Staggered Arrangement with Three Disturbance Bodies Around the Upstream Cylinder
Authors: Sutardi Banta Cut
Published: October 2023

Studies on flow through cylinders have been widely carried out, both experimentally and numerically. The purpose of those studies is to obtain information about flow phenomena around the cylinder arrangement, such as aerodynamic forces, vortex shedding, and vortex-induced vibration. This study aims to evaluate the flow characteristics that pass through three circular cylinders arranged in a stagger and reduce the drag force (CD) by adding 3 disturbance bodies (DB) around the upstream cylinder. The longitudinal distance L/D varies from 1.5 to 4.0, while the transversal distance T/D is kept constant. Next, the diameter ratio d/D is set to 0.16. The diameter of cylinder 1, D=25 mm, and the diameter of the DB, d=4 mm. The DB is placed around cylinder 1 at three angle locations with a gap, δ=4 mm. The study is performed using Ansys fluent® 19.1 software in 2-D unsteady RANS with the transition k-kl-omega turbulence model. The flow Reynolds number based on D is22x104. The results showed that the L/D and the use of DB affect the cylinderdrag coefficient (CD). There is a CD reduction for cylinder 1 up to 20% atL/D=3.0. For cylinders 2 and 3, the reduction in CD occurred at L/D=4.0 upto approximately 13% and 17%, respectively.
Evaluating the Nonlinear Dynamic Stiffness of Rail Pad using Finite Element Method
Authors: Abdul Wahab Abdul Malek
Published: October 2023

Unwanted vibration and noise from railroads have a significant negative impact on the environment, causing damage to roads, buildings, and other structures. To mitigate this condition, rail pads have been installed as dampers to lessen the impact of vibration and shock on the railway track. The rail pad is made of a polymeric substance having nonlinear properties. This research examined the dynamic stiffness of rail pads made of thermoplastic elastomers (TPEs). ANSYS software was used to estimate the impact of temperature, toe load, and frequency under dynamic loading. The three-dimensional (3D) finite element model (FE) was created based on hyperelastic theory. The dynamic stiffness of the interlayer decreases with increasing temperature. For the effect of peak load and frequency, both parameters were directly proportional to dynamic stiffness. An increase in either parameter results in a stiffening of the interlayer. Frequency has the least effect on the dynamic stiffness of the track bed compared to temperature and peak load, with the average percentage difference between high and low being 28.31%, 55.57%, and 21.9%, respectively.
Reducing The Risk of Agglomeration and Shrinkage Ceramic Body from Al2O3-ZrO2 Composition
Authors: Tamin Norfauzi
Published: October 2023

This study introduces the effect of ceramic composition that consists of Alumina (Al2O3)-Zirconia (ZrO2)-Chromia (Cr2O3) compositions on agglomerate and shrinkage for cutting tool development. Shrinkage is a problem in the development of ceramic cutting tools other than the occurrence of particle agglomerate on the body structure. Finer grain size significantly contributes to the ceramic body's shrinkage and agglomeration. This study analyzed grain size and its relationship with shrinkage and agglomerates. The powders were ball-milled with 80 wt% Al2O3 -20 wt% ZrO2 -0.6 wt% Cr2O3 and then compacted and sintered at 1400 °C to examine their shrinkage and investigate microstructure by scanning electron microscopy (SEM) machine. The results show that ZrO2 has a larger particle size of 6.10 μm and Cr2O3 has a finer measure of 1.24 μm. When blended with the ball mill, the mix of Al2O3- ZrO2-Cr2O3 was obtained is 7.30 μm, showing that the ball mill can uniformly mix all the particles and reduce the risk of agglomeration. The microstructural analysis found that Cr2O3 covers and fills up the space between Al2O3 and ZrO2 compared to without Cr2O3. The combination of agglomerate and shrinkage of Al2O3-ZrO2-Cr2O3 was responsible for the performance of the ceramic cutting tool fabricated.
Influence of Nano Additives on Performance, Combustion, and Emission Characteristics of Diesel Engine using Tamarind Oil Methyl Ester-Diesel Fuel Blends
Authors: Rao Bikkavolu Joga
Published: October 2023

Hazardous emissions majorly NOx and the poor performance of alternative fuels (biodiesel/its blends) are global concerns, as fossil fuel depletion and rising energy prices encourage researchers to rely on alternative energy sources with the addition of nano additives in the recent decade. The current experimental study investigates the performance, combustion, and emission characteristics of biodiesel-diesel mixtures dispersed with titanium dioxide (TiO2) as a fuel additive on a 1-cylinder diesel engine. TiO2 was dispersed in a Tamarind Oil Methyl Ester (TOME)-diesel blend (B20) in three concentrations of 40, 80, and 120 ppm via ultrasonication in the presence of QPAN80 surfactant to enhance the stability of the prepared fuel sample. A ratio of 1:4 TiO2:QPAN80 was found to produce the highest stability and homogeneity which is evidenced by the characterization of TiO2. The engine tests revealed that the greatest decrement in BSFC, CO, HC, and NOx was observed as 15.2%, 15.2%, 11.10%, and 9.06%, and the maximum BTE, HRR,and CP were improved by 9.76%, 50.32 J/degree, and 50.32 bar for the B20T80 blend correlated with B20 blend. Thus, the inclusion of TiO2 nano additives improved overall engine performance and decreased emissions of CI engines significantly.
Performance of Hybrid Al2O3:SiO2 W:EG in PEM Fuel Cell Distributor Plate
Authors: Zakaria Irnie Azlin
Published: October 2023

Efficient thermal management is essential for the optimal performance and durability of the Proton Exchange Membrane Fuel Cell (PEMFC). However, the conventional passive cooling methods require a larger heat exchanger for better heat dissipation. Alternatively, nanofluids as a coolant have gained attention recently due to their enhanced heat transfer properties. This investigation aims to evaluate the thermal performance of hybrid nanofluids in a distributor type of PEMFC cooling plate. In this investigation, 0.5% volume concentration of mono Al2O3, mono SiO2 nanofluids, and hybrid Al2O3:SiO2 nanofluids with a mixture ratio of 10:90, 30:70, 50:50, and 70:30 in 60:40 W:EG were investigated. The cooling plate was modelled and a fixed heat flux of 6500 w/m2 was applied to replicate the actual working parameter of PEMFC. The study shows that the heat transfer coefficient was improved by 61% in 10:90 hybrid nanofluids of Al2O3:SiO2 in W:EG in comparison to the base fluid. Meanwhile, the accompanied pressure drops in 10:90 hybrid nanofluids of Al2O3:SiO2 in W:EG show a reduction up to 4.38 times lower as compared to single Al2O3 nanofluids at Re 1800. This is advantageous since it will reduce the parasitic loss related to the PEM fuel cell.

Analyzing monstrous maternal in “Jendela” and “A Mother’s Love” interior mise-en-scene
Authors: Widyaevan Dea Aulia
Published: October 2023

Background: The storytelling and narrative approaches surpassed the study of the interior and cinematic by the idea of staging. In film production, the use of interior elements to aid storytelling is called interior mise-en-scene. However, more research still needs to be done on how spatial metaphors in the interior mise-en-scene are explored. The spatial metaphor is central to creating atmosphere and setting based on film narratives. Therefore, this article examines a spatial metaphor in the horror film mise-en-scene, focusing on monstrous maternity. The case studies are the film ‘A Mother’s love’ (Joko Anwar, Indonesia) and ‘Jendela’ (M. Subash Abdullah, Malaysia). Both films portray the woman protagonist as a psychotic character who haunts their own house. Purpose: The article aims to find spatial metaphors to represent the idea of monstrous maternal as a horror motif. Methods: Through qualitative and literature review, the element of the interior mise-en-scene and abjection theory has been analyzed to find meaning in spatial language. Results: As a result, the spatial metaphor in the film portrays the idea of topo analysis- the topography of the intimate being in the house. Many spaces are composed in dream scene situation, and the use of liminal space become central to supernatural narratives. A distorted play camera frames the space, engaging the audience to enter the character’s mind. Implications: This research contributes to how spatial metaphor in film can aid storytelling in interior design. The interior mise-en-scene helps the designer translate the narrative’s text into a spatial dimension through the staging technique.

Democracia, orden internacional y guerra en Ucrania
Authors:   Investigador sénior, Programa Democracia, Conflicto y Gobernanza, Carnegie Europe, Youngs Richard
Published: October 2023

¿Qué lugar ocupa la democracia en el cambiante orden internacional? Existe el temor de que un orden de carácter más geopolítico agrave la crisis generalizada de la democracia; o que un orden más plural diluya los esfuerzos realizados para defender las normas que la rigen. Sin embargo, aunque las últimas tendencias políticas y normativas corroboran esta preocupación, la invasión rusa de Ucrania ha evidenciado, en cierta medida, la importancia de defender los valores democráticos en todo el mundo. Este artículo examina, a nivel global, el impacto que las tensiones geopolíticas y los cambios actuales en el orden internacional tienen sobre la democracia; y, en el contexto de la crisis de sentido que afecta a las democracias, si la guerra rusa contra Ucrania ha servido tanto de catalizador de las dimensiones internacionales del apoyo a la democracia como de factor de intensificación de su fragilidad.

Estados Unidos y China se encuentran sumidos en una rivalidad estratégica en muchos ámbitos, como el comercial y financiero, aunque el más importante está siendo el tecnológico. Al respecto, y dado el rápido avance de esta rivalidad, se puede hablar de dos ecosistemas cada vez más claramente definidos, si bien aún interrelacionados, en las áreas de los semiconductores y la inteligencia artificial (IA). A su vez, las cadenas de producción global se están reconfigurando, en parte, por motivos económicos, pero sin duda también por cuestiones geopolíticas. Dichos cambios no solo afectarán los flujos comerciales en todo el mundo, sino también la inversión extranjera directa (IED), e irán bifurcando paulatinamente la producción en dos grandes bloques, basados en tecnologías y estándares diferentes. ¿Dónde se ubica la Unión Europea (UE) en este contexto?

Published: October 2023

Este artículo examina la gobernanza compleja, multilateral y policéntrica de la agenda climática, así como la gestión del conocimiento que se articula alrededor del Panel Intergubernamental de Expertos sobre el Cambio Climático (IPCC). Partiendo de la base de la dificultad que esta gobernanza implica, el artículo muestra cómo esta ha sido capaz de producir avances en la lucha contra la crisis climática. La gobernanza de la acción climática se asemeja a una red de redes, un tupido entramado de iniciativas públicas, privadas, sociales, tecnológicas, de conocimiento y de espacios intersectoriales. La complejidad para garantizar el cumplimiento de lo acordado es indudable, en muchos aspectos, pero hasta la fecha se ha demostrado lo único viable. Fuertemente dependiente del contexto global, la transición ecológica es una oportunidad para dar un salto cualitativo en el contexto de la crisis energética provocada por la invasión de Ucrania.

Looseness of high-strength wind turbine bolts is one of the main types of mechanical failure that threaten the quality and safety of wind turbines, and how to non-destructively detect bolt loosening is essential to accurate assessment of operational reliability of wind turbine structures. Therefore, to address the issue of looseness detection of high-strength wind turbine bolts, this paper proposes a non-destructive detection method based on digital image correlation (DIC). Firstly, the mathematical relationships between the inplane displacement component of the bolt’s nut surface, the bolt’s preload force loss and the bolt loosening angle are both deduced theoretically. Then, experimental measurements are respectively conducted with DIC with different small bolt loosening angles. The results show that the bolt loosening angle detection method based on DIC has a detection accuracy of over 95%, and the bolt’s preload force loss evaluated by the deduced relationship has a good agreement with the empirical value. Therefore, the proposed DIC-based bolt loosening angle detection method can meet the requirements of engineering inspection, and can achieve quantitative assessment of preload forces loss of wind turbine bolt.

Published: October 2023

Epilepsy affects approximately 50 million of people worldwide and 30% of them are resistant to drugs. Neuromodulation is becoming a key option in patients with drug-resistant epilepsy who are not feasible for resective surgery. Vagus nerve stimulation (VNS) is the most commonly used adjunctive neuromodulatory method in every patient aged 4 years and older who is unsuitable for resective surgery. It is a minimally invasive, non-teratogenic, extracranial pacemaker-like device which delivers electrical stimuli to the vagus nerve and desynchronize aberrant cerebral rhythms involved in epileptogenesis. In this review we approached the information and clinical data of VNS development history, clinical applications and possible mechanism of action. We will also review optimal stimulation parameters and information about closed and open loop devices. Vagus nerve stimulation is safe, efficient with no significant side effects and substantial cost-saving benefit, that also shows an important improvement in mood, behavior, cognition and quality of life. The overall responder rate was observed in more than 50% of patients. On the other hand, it is not clear which patients will respond to this method of treatment and why the response is not immediate, there are no available biomarkers or other features like age, sex, seizure type/epileptic syndrome to predict response to vagus nerve stimulation therapy. The VNS Therapy System continues to be an important prospect in the treatment of pharmacoresistant epilepsy, that requires further studies in order to ensure the most advantageous therapeutic response.

Biting midges are insects which annoy horses as they cause discomfort and by the sucking of blood, they cause painful lesions that, in certain cases, can trigger acute allergic reactions. They also act as potential vectors of many pathogens of bacterial, viral and parasitic origin. The aim of this study was to investigate seasonal dynamics, abundance and species composition of biting midges, and implementing protection options at the Equestrian centre of the University of Veterinary Medicine and Pharmacy (UVMP) in Košice in the years 2021 and 2022. During this time period (of 2021 and 2022), we captured 4797 biting midges. Our results showed that in 2021 the most frequently captured species were C. obsoletus/C. scoticus (prevalence 86.6 %), followed by C. punctatus and C. pulicaris (prevalence 5.37 % and 3.86 %, resp.). In addition, C. lupicaris, C. newsteadi, C. furcillatus, C. festivipennis, C. slovacus, C. tauricus, C. clastrieri, C. dewulfi, C. fagineus and C. circumscriptus were identified as the minority species. In this year, the highest abundance of these insects (1758 biting midges) was observed at the end of June. In 2022, we detected a clear dominance of C. obsoletus/C. scoticus (prevalence 97.0 %) and the highest number of biting midges (655) was captured in mid-May). In this year, the minority species included, C. pulicaris, C. punctatus and C. lupicaris. The identification of the host blood showed that man (Homo sapiens) was the dominant host, namely of 80 % of the examined biting midges of species C. obsoletus/C. scoticus, C. dewulfi, C. punctatus and C. festivipennis. In one female of species C. fagineus we identified the host blood from horses (Equus caballusi). In 2022, we detected the blood of a domestic rabbit (Oryctolagus cuniculus) in the species of C. obsoletus/C. scoticus.

This article provides a comprehensive analysis of dysplasia trochlea in dogs, summarizing the most recent findings in the field and highlighting important new findings, as well as, areas that require further research. The anatomy of the knee and the trochlea femoris, as well as its function in maintaining knee joint stability, are covered in the first section. The accurate diagnosis of orthopaedic disorders, and injuries are necessary for efficient treatment, and this is made possible by understanding the anatomy of the knee. The factors that can affect the onset, development, and course of the disease are included in the section that follows, which discusses the etiology, and pathophysiology. Veterinary surgeons must measure trochlear femur dysplasia in dogs in order to determine the severity of the condition and the best course of treatment. It is typically assessed by looking at X-ray images and assigning a score, however, this can differ from one individual to another. New measurement techniques that give a better level of objectivity and precision, like CT scans or MRIs, are now being tested.

The paper analyses the surplus and production in the period 2010-2021 for total vegetables, field-grown vegetables, vegetables grown in glasshouses and greenhouses, vegetables from home gardens and the main vegetable species: potatoes, tomatoes, aubergines, peppers, dried onions, white cabbage. For these, the main statistical indicators were calculated on the basis of areas and yields, that is, standard deviation, coefficient of variation. Romania's place in the European Union in terms of area and production of the crops analysed was also identified. Thus, Romania is at the top of the ranking for the area cultivated with cabbage (19.45 thousand hectares), it ranks 2nd for the area cultivated with aubergines (4.94 thousand hectares) and peppers (10.37 thousand hectares), and 3rd for the area cultivated with tomatoes (18.13 thousand hectares). In terms of production, Romania ranks 3rd for the production of cabbage (548.3 thousand tonnes) and tomatoes (95.86 thousand tonnes). According to the coefficient of variation, for the production of vegetable crops, the variation of the data series is small and the annual rate is negative, except for vegetables grown in glasshouses (4.66%) and peppers (0.19%). For area, the annual rate is negative, except for vegetables grown in glasshouses (4.64%).
