The aim of this research was to identify the variability of the different wheat flours available in Romania. In this study 39 different wheat flours were selected and the following parameters were analyzed in the laboratory: moisture content, ash content, gluten content (wet and dry) and wet gluten spreading. The tested flours were classified into four different classes according to their ash content: 480 (ash content 0.48%) (N = 11), 550 (0.55%) (N = 9), 650 (0.65%) (N = 8), 1100 (1.1%) (N = 11). Mathematical and statistical methods were used to analyze the obtained results: descriptive statistics, box-plot, Spearman correlation and hierarchical cluster analysis. The results revealed that moisture content varied between 9.5 and 11.8%. In terms of ash content, the lowest and highest measured values were 0.427–2.04 g/100 g. The average wet gluten content of the studied flours varied between 30 and 32%, while the average dry gluten content was 12.8%. The findings indicate that the moisture content of all examined flour samples was within permissible levels for extended storage, aligning with established standards. Gluten is a key and essential parameter for bread making because influences the dough mixing and baking properties. The mineral content, represented by ash content, is influenced by cereal type and milling process, with wheat's ash content ranging between 1.5 and 2%. Flours with high wet gluten content (> 34%) can be used to improve the properties of lower quality flours. Further studies are necessary in order to determine the possible health effects of different cereal varieties.

This study is focused on the evolution of PM2.5, PM10, NOx and SO2, concentrations, and meteorological parameters from 2010 to 2022, at urban and suburban area in the two Romanian city: Brasov and Iasi. The daily patterns of most pollutants in urban and suburban areas, are strongly linked to land-traffic emissions. The seasonal differences were observation of the studied air pollutants displays visible decreasing in warm period and increased concentrations in cold period. Significant higher (25%- Brasov, 28%- Iasi) PM10 were found in urban area concentration probably caused by enhanced vehicular emissions over these areas induced by urban planning and mobility policies. The average relative risk caused by PM10 for all-cause mortality in the urban region was 1.021 (±0.004) in Brasov, and significantly higher in Iasi 1.030 (±0.005). In suburban regions this risk was lower with 33 % 1.014 (±0.006) in Brasov and 30 % 1.021 (±0.003) in Iasi. The main objective of this research was to identify the difference of air pollutants and meteorological parameters in the urban and suburban region of the studied city. © 2023 The Authors LA - English DB - MTMT ER - TY - JOUR AU - Bodor, Katalin AU - Tokos, Bernadett AU - Bodor, Zsolt AU - Keresztesi, Ágnes AU - Lászlo, Szilvia AU - Garbacea, George AU - Szép, Róbert TI - Hydro-geochemical characterization of the main European mineral water brands JF - JOURNAL OF FOOD COMPOSITION AND ANALYSIS J2 - J FOOD COMPOS ANAL VL - 122 PY - 2023 PG - 12 SN - 0889-1575 DO - 10.1016/j.jfca.2023.105438 UR - https://m2.mtmt.hu/api/publication/34005950 ID - 34005950 LA - English DB - MTMT ER - TY - JOUR AU - Bodor, Katalin AU - Szép, Róbert AU - Bodor, Zsolt TI - The human health risk assessment of particulate air pollution (PM2.5 and PM10) in Romania JF - TOXICOLOGY REPORTS J2 - TOXICOL REPORTS VL - 9 PY - 2022 SP - 556 EP - 562 PG - 7 SN - 2214-7500 DO - 10.1016/j.toxrep.2022.03.022 UR - https://m2.mtmt.hu/api/publication/32824896 ID - 32824896 LA - English DB - MTMT ER - TY - JOUR AU - Bodor, Katalin AU - Boga, Réka AU - Pernyeszi, Tímea Judit AU - Tonk, Szende AU - Deak, Gyorgy TI - VARIATION OF PM10 CONCENTRATION DEPENDING ON THE METEOROLOGICAL PARAMETERS IN TWO BUCHAREST MONITORING STATIONS (IN GREEN AREAS) JF - PRESENT ENVIRONMENT AND SUSTAINABLE DEVELOPMENT J2 - PRESENT ENVIRONMENT AND SUSTAINABLE DEVELOPMENT VL - 14 PY - 2020 IS - 1 SP - 277 EP - 292 PG - 16 SN - 1843-5971 DO - 10.15551/pesd2020141022 UR - https://m2.mtmt.hu/api/publication/31782981 ID - 31782981 AB - This study presents the assessment of the PM10 emissions in areas from the south of Bucharest and Ilfov county, for a period of 11 years, during 2008-2018, taking into consideration the most important meteorological parameters with influence to air pollution, such as relative humidity, temperature, wind direction, and wind speed. During the study period, the mean annual concentrations of PM10 decreased from 43.92 mu g/m(3) to 29.67 mu g/m(3), expressed as a percentage change the decrease was 35.45% and 29.03% at the B-4 and B-7 stations, respectively. The Pearson correlation coefficient was significantly higher in the cold season (November-April). In order to further investigate the relations of air quality and wind direction pollution roses were calculated and the results indicate that the highest concentrations of PM10 occur in B-4 and B-7 at the southwestern and west direction of wind.

This solid substance had BiOI-like, lamellar and deflected structure resulting from CuI ion incorporation in the Bi2O2 layers. The as-prepared substance was fully characterized by XRD, Raman, far IR, UV–DR, XP spectroscopies, thermal (TG-DTG) and analytical (ICP-MS, SEM-EDX) methods, electron microscopies (SEM, TEM) as well as BET surface area measurements. By performing Ullmann-type CN– coupling reactions between aryl halides and aqueous ammonia, its catalytic capabilities were tested. The effects of solvents, added base and catalyst loading as well as reaction time and reaction temperature were scrutinized, and a green way for the reaction was identified. The recyclability of the catalyst without the loss of activity and its general applicability for a wide range of aryl halides were also demonstrated. © 2020 The Author(s) LA - English DB - MTMT ER - TY - JOUR AU - Keresztesi, Ágnes AU - Ion-Andrei, Nita AU - Marius-Victor, Birsan AU - Bodor, Zsolt AU - Pernyeszi, Tímea Judit AU - Miruna, Mihaela Micheu AU - Szép, Róbert TI - Assessing the variations in the chemical composition of rainwater and air masses using the zonal and meridional index JF - ATMOSPHERIC RESEARCH J2 - ATMOS RES VL - 237 PY - 2020 PG - 16 SN - 0169-8095 DO - 10.1016/j.atmosres.2020.104846 UR - https://m2.mtmt.hu/api/publication/31156817 ID - 31156817 LA - English DB - MTMT ER - TY - JOUR AU - Meiszterics, Zoltán AU - Asserghine, Abdelilah AU - Kiss, András AU - Nagy, Lívia AU - Zsebe, Tamás AU - Nagy, Géza TI - Scanning Electrochemical Microscopy (SECM) Investigation of 3D Printed Parts Produced by CMT Welding Technology JF - ELECTROANALYSIS J2 - ELECTROANAL VL - 32 PY - 2020 IS - 4 SP - 820 EP - 826 PG - 7 SN - 1040-0397 DO - 10.1002/elan.201900678 UR - https://m2.mtmt.hu/api/publication/31132762 ID - 31132762 N1 - Funding Agency and Grant Number: Hungarian Research Grant: NKFI [K125244]; University of Pecs [GINOP-2.3.2-15-2016-00022, EFOP.-3.6.1.-16-2016-00004] Funding text: The work was supported by the Hungarian Research Grant: NKFI No.: K125244 as well as by the University of Pecs GINOP-2.3.2-15-2016-00022 and EFOP.-3.6.1.-16-2016-00004 Biomedical Engineering Project.
