In applied sciences, researchers use particular scientific methods to achieve practical goals. You can think of applied sciences as a broad, integrated area of various scientific fields that involve agronomy, agriculture, food science, medicine, engineering, computer science, and many other natural and social science disciplines. The main goal of applied science is to provide more knowledge and practical applications

Most of the misconceptions listed here were collected over the course of fifty years, mainly from practising farmers and students of agriculture. Naturally I am not suggesting that the readers of this journal are not clear about the incorrectness of most of these ideas, but some of these errors are the subject of serious debate even among specialists.

It is interesting to note that people working in other fields, who have never studied agricultural chemistry, are often more open to new knowledge than those who have. This can be attributed to both deficiencies in the teaching of agricultural chemistry and

Greenhouse plastic contaminations in agricultural soils were studied to quantify and examine the macroplastic and microplastic contaminants on the soil surface, soil profile, and groundwater under greenhouse farmland. Random sampling was used to select three areas in a greenhouse farm where macroplastic and microplastic data were collected. Four composite samples were collected from shallow (0–20 cm) and deep (20–40 cm) soils for each sampling point, respectively. Three soil profiles were dug, and samples were collected at intervals of 20 cm. Groundwater samples were also collected from the same profiles at a depth of 100 cm. Microplastics were extracted using predigestion of organic matter with 30% H2O2and density separation with ZnCl2。The total mass of macroplastics in the greenhouse farmland was 6.4 kg ha–1。聚乙烯和聚氯乙烯是主要的塑料结构,主尺寸分别为1-5和0.5-1.0 cm。总体而言,温室土壤中微塑料的平均丰度为225±61.69件/kg,显性尺寸结构为2-3 mm。深度为0-20和20-40 cm处的平均微塑料浓度分别为300±93和150.0±76.3件/kg。地下水中的平均微型浓度为2.3片/L,纤维是主要的塑料结构。鉴于在温室土壤,土壤剖面和地下水中发现了微塑料,我们建议在温室农田上仔细清洁和处置塑料,并进一步研究以阐明土壤剖面和地下水中的微塑性污染水平。

Soybean seeds were germinated on an industrial scale after soaking for 0–56 h to produce a special additive for food industrial use. The germination process of three soybean varieties was monitored with near-infrared (NIR) spectroscopy based on changes in the amount, status, or character of the water. This paper evaluates the “waterless” NIR spectra of sound, germinated, and heat treated seeds to try to follow the fine details of the germination process. The germination process was analysed with the help of cluster analysis (CA), principal component analysis (PCA), and polar qualification system (PQS) as statistical and chemometric methods. PCA proved to be the most sensitive spectrum evaluation method to follow the fine details of germination. The applied NIR method is suitable for non-destructively, real-time monitoring of the non-linear nature of germination.

本文讨论了由于应用了所有类型的矩形空气流而改善前提中空气分布的主题问题:平坦,轴对称和矩形。本文的目的是对所有类型的矩形空气流的研究,即确定空气速度衰减系数,空气动力学局部电阻系数和噪声水平的分析依赖性,从缝隙长度到高度的比率。优化流入缝隙的比率。已经确定,增加的流入缝侧比导致空气速度衰减系数降低,并导致矩形缝隙的噪声水平和电阻系数的增加。矩形狭缝侧面的最佳比率取决于空气动力学和能量学以及声音电平的结合。

Wind generation is regarded by many as the future of renewable energy source, but the difficulty of recycling end-of-life wind turbine components could create another kind of environmental pollution. Either landfill or incineration of end-of-life wind turbine components will cause environmental hazards. However, the current recycling technology is immature and economical. Make clean energy ‘cleaner’! The recycling of end-of-life wind turbine rotor hub and blades has become a new goal and task for architects and designers. This article uses a real project reconstructed by end-of-life wind turbine components to demonstrate the positive role of spatial narrative in achieving low-carbon and sustainable design.

The floodplains of the Tisza River, stretching across the eastern part of Hungary, are often affected by riverine and inland excess water flooding and draught. This paper investigates a possible solution to this problem utilizing the water retention capabilities of old floodplains. In this study, the effect of the position of the inlet structures of a floodplain, near Csongrád town, was examined with HEC-RAS 1D-2D coupled model. Based on the results, the rules of the deep floodplain selection were determined. On the extended model, the possibilities of a deep floodplain storage area chain have been explored. According to the estimate, more than 2.36 km3potential storage capacity is available along the Hungarian section of the Tisza River.

Nature-based solutions use a holistic viewpoint to address social challenges while providing environmental, social and economic benefits simultaneously. The Victoria Quay is a historical space with complex social and environmental issues. This study uses an investigation-oriented method to explore the re-planning strategies. The environmental problems are addressed by extending the green infrastructure into the site to recover the ecological corridor and alleviate flooding risks. The originally single land-use type is changed, and several historical buildings are transformed into landmarks to improve the connection with city center by linking the ‘golden route’. All the proposed measures tried to reactivate the various relationships rather than merely renew the Victoria Quay.

抗真菌疾病(匹威)种间抢e varieties are playing an important role as an alternative for organic wine production. Organic (bio) wines are demanded by numerous conscious consumers around the globe. They choose this kind of wines predominantly because of the absence of synthetic pesticides, fertilisers and sustainable agriculture. Resistant grape growing moreover results in additional environmental and health benefits. Nero and Bianca are among Hungary's most promising interspecific grape cultivars gaining international interest recently, there are, however, limited vitivinicultural knowledge on them. Our aim was to examine the flavonoid and anthocyanin composition for both interspecific varieties during different harvest times in two consecutive vintages. The date of harvest and vintage played a significant effect on grape and wine quality.
