In this work, we studied the impact of harvesting time on Fusarium mycotoxin occurrence in spring wheat and the effect of mycotoxin contamination on the quality of these grains. The spring wheat grains (Triticum aestivum L.) were collected in 2016–2018 when the crop had reached full maturity, 10 ± 2 days and 17 ± 3 days after full maturity. The grain samples were analyzed for Fusarium infection and co-contamination with mycotoxins deoxynivalenol (DON), zearalenone (ZEA), and T-2 toxin (T-2), as well as the quality of the wheat grains (mass per hectolitre, contents of protein, starch, ash and fat, particle size index (PSI), falling number, sedimentation, wet gluten content, and gluten index). The occurrence of Fusarium spp. fungi and the mycotoxins produced by them in the grains was mostly influenced by the harvesting time and meteorological conditions. The correlations between Fusarium species and the mycotoxins produced by them in the grains of spring wheat showed F. graminearum to be a dominant species, and as a result, higher concentrations of DON and ZEA were determined. The co-occurrence of all the three mycotoxins analyzed (deoxynivalenol, zearalenone, and T-2 toxin) was identified in wheat. In rainy years, a delay in harvesting resulted in diminished grain quality of spring wheat, as indicated by grain mass per hectolitre and falling number. Negative correlations were found in highly contaminated grains between mycotoxins (DON, ZEA, and T-2) and falling number and grain mass per hectolitre values.

The Impact

Abiotic stresses varyingly affect the grain composition and quality of food legumes. This paper is aimed at discussing the impact of abiotic stresses on the grain composition and quality of food legumes. As protein is the main grain constituent of food legumes for which it is being consumed by humans as a cheap protein source, abiotic stresses such as heat, cold, drought, salinity and heavy metals alter this grain protein content in different dimensions for different food legumes. Moreover, other valuable constituents such as starch, soluble sugar, oil, fatty acid and fiber content are affected differently by the abiotic stresses. The diverse impact of these abiotic stresses ultimately declines the grain quality and yield of food legumes. As food legumes play a vital role in the nutritional diet of millions of people in the world and are occasionally denoted as the meat of poor people, it is important to recognize that the sustainable production of food legumes, even under various environmental stresses, has the potential to ensure protein security for people globally. Therefore, it has become a necessity to improve the productivity and quality of food legumes under abiotic stresses through proper crop management and improved breeding strategies, thus enhancing food and economic security to the farmers, particularly in the developing countries of the world.

The Impact

The paper presents the results of a study of the impact caused by the discharge of treated sewage from the south-west Attiki area to the south-east coast of the Saronicos Gulf. The study involved the application of a eutrophication-dissolved oxygen model which, following validation on the basis of field measurements, was applied to predict the impact of three different biological treatment configurations, with and without nutrients removal, as well as three alternative disposal sites on the quality of the receiving waters. The simulation results show that nitrogen is the limiting nutrient and that its removal during treatment results in a substantial improvement of the quality of the recipient. The disposal site is a critical factor in the case of a biological treatment scheme exhibiting carbon removal, but it is of limited importance in the case of treatment systems with nitrogen removal.

Corn Grain

Purpose. The aim of the research conducted during 2016-2019 was to determine the impact of technological methods on the indicators of corn grain quality to optimize the elements of growing technology depending on the directions of use in conditions of the Forest-Steppe natural zone of Ukraine. Methods – field, quantitative and weight, chemical, comparative and calculation, mathematical and statistical. Results. On the results of the research, dependences of formation of quality of grain on the content of protein, starch, fat in it and correlation dependencies between these indicators and yield of corn have been revealed. The best quality of grain of a forage and food direction is formed when applying high doses of mineral fertilizers, and for processing on bioethanol the optimal content of starch and protein is guaranteed at optimum and raised level of fertilizing. It was established that the content of protein, starch and fat had less effect on their yield from 1 hectare than the general yield level. The technologies of cultivation of different intensity as to their possible application for the production of grain of different directions of use with the given quality parameters, the yield of protein, starch, fat and bioethanol have been evaluated. Conclusions. The technology of corn growing with complex application of intensification elements in conditions of the Forest-Steppe zone, which includes introduction of N240P120K240 on the background of by-products of its predecessor, application of the soil and insurance herbicide, plant growth and micro-fertilizers is suitable for fodder and food purposes and ensured the yield of 12.1 t/ha of grain with protein content and yield – 10.56% and 1.28 t/ha, fat – 4.29% and 0.52 t/ha, starch – 71.27% and 8.62 t/ha. For processing on bioethanol effective is the technology of corn growing with the introduction of N180P120K180, by-products of the predecessor, soil herbicide and bio-stimulants, which provided a yield of 9.76 t/ha of grain with a starch content of 72.26% for the yield of 7.05 t/ha and yield of bioethanol at the level of 3982 l/ha.

The Impact

A 2D current and water quality model was set up with Delft3D-FLOW in this research, which was well calibrated and verified with the observed tidal levels and velocities. Considered with the project of the Qingcaosha Water Source, Pollution concentration distribution caused by sewage outfalls in the south bank of the Yangtze River during a neap tide of dry season is simulated and the computed results show: a high pollution zone appears near the south shore, and moves upward with flood flow and downward with ebb flow, however, it is bounded a limit region around the outfalls. During the tidal period, the water quality of the Qingcaosha water source can be classified as the second class water, which can ensure the normal water supply as the Shanghai water source. It is suggested that the regular monitoring water quality in this high pollution zone should be put into practice to ensure the water quality of water sourecs. The Yangtze River is adjacent to the East Sea and it’s the largest river in China, with obvious seasonal variant runoff and tidal flow. The Yangtze River was bifurcated by Chongming Island to south and north branch from Xuliujing, most of the flow go down through the south branch. The south branch was divided into south and north channel by Changxing Island and Hengsha Island. The south channel was bifurcated by Jiuduansha Shoal to south and north passage, three bifurcation areas and four estuarine outlets were formed (see Fig 1.)

In Romania, territorial/spatial development is understood as the process of transforming the geography of inhabited territories, taking into consideration: territorial planning, urban planning and development, public works, habitat and housing, construction. It is governed by the regulatory framework in force, aligning its policies and strategies with the main reference documents at the European level. The construction sector is a key sector for investment and economic development, playing an important role in achieving the sustainable development objectives through the impact that the quality of construction has on the quality of life and by ensuring the necessary environment for most human activities. The building permit is the final authority act of the local public administration on the basis of which the execution of construction works is allowed in accordance with the measures provided by law regarding the placement, design, construction, operation and post-use of buildings. Starting from comparative structural analyses on the number of building permits issued by the local public administrations in the South-East Region, the objective of this research has been to obtain a dynamic image, through a quantitative assessment, of the number of building permits issued for residential buildings, highlighting the way in which they directly influence the sustainable development of urban and rural localities in the South-East Region of Romania.
