The present study hypothesis resulted in the identification of a viable system of indicators that might play an important role in the measurement of sustainable development. The main purpose of our research is the development of a watershed sustainability index and its application for the Motru River basin. This catchment area covers an area of 1,895 km² within southwestern Romania. Applying the watershed...
Fungi of the genus Fusarium infect cereal crops during the growing season and cause head blight (FHB). Their secondary metabolites (mycotoxins) contaminate grain. Mycotoxins are not degraded during standard food and feed processing operations or in vivo digestion, and are dangerous to human health. In a three-year field experiment we evaluated the effects of biological control agents and a plant biostimulator...
Long-term water-energy balance is a major concern in hydrology and water resource management. Evapotranspiration is a key factor for achieving water-energy balance. In this study, we used a simple water and energy balance equation to compare the effects of precipitation and potential evapotranspiration on actual evapotranspiration – mathematically and theoretically. The results showed that, in Baiyangdian...
An intermittent aerobic process has been developed to effectively remove nitrogen from polluted rivers. In addition, a chemometric model was developed to achieve simultaneous rapid analysis of total nitrogen, ammonia nitrogen, and nitrite nitrogen based on near-infrared spectroscopy data combined with a support vector machine. An intermittent aeration process showed that total nitrogen decreased from...
Total suspended particulates (TSP) in ambient air of three sites representing a gradient transect of urbanization along the western coast of Saudi Arabia were collected and their heavy metal contents were analyzed. The sampling was conducted at three sites simultaneously between 16 June to 7 July 2013, 17 September to 1 October 2013 (summer), and 23 December 2013 to 30 January 2014 (winter). The concentration...
Wastewater recycling technologies have been widely used in tanneries to reduce environmental impacts. However, only a few recycling methods have been developed for vegetable tanning processes due to limited knowledge of their wastewaters. In this study, the structures of the polyphenols in the larch tanning wastewater (LTW) and commercial larch tannin (CLT) were characterized with spectrographic and...
To illustrate the distribution pattern of soil organic carbon density (SOCD) in a small karst watershed and its main influencing factors, this research quantitatively analyzed the spatial heterogeneity and distribution characteristics of SOCD using 2,755 thoroughly investigated soil profile samples; field point sampling, laboratory determination, and geo-statistical analysis were used, and the major...
The number of studies using prediction models on measuring soil loss and/or sediment yield has been continuously increasing since these models are considered timely and cost-effective. Similarly, in this study, we used the GeoWEPP model to determine how much soil is being lost and the amount of sediment being yielded from Godrahav Creek Watershed (GCW) located in northeastern Turkey. Because the watershed...
This paper presents methodology for constructing a statistical model to forecast food-to-mass ratio (F/M). In the model, wastewater inflow (Q), biochemical oxygen demand (BOD5) and mixed liquor suspended solids (MLSS) were modelled separately using artificial neural networks (ANN) and multivariate adaptive regression splines (MARS). To compute the value of MLSS, the quality indicators of influent...
The study was carried out in 2015 in the experimental orchard of the Agropodrinje apple introduction centre in the Gorazde area. The impact of different methods of calcium fertilizer application on fruit quality and calcium content in the ‘Idared’ fruit of an 8-year-old apple tree were studied. Fruit mineral composition and quality parameters were estimated after harvest. Calcium fertilizers used...
In recent years the focus on organic farming has been emphasised because of the negative effects of conventional farming. Any persuasion geared toward making farmers adopt organic farming methods requires an investigation of their current attitude toward organic farming. The main purpose of this descriptive-correlational study was to investigate the effective factors that determine farmers’ attitudes...
China’s iron and steel sector has met many obstacles, such as high energy consumption and huge CO₂ emissions. In order to deal with these problems, the Chinese government has launched a series of corresponding policies. With the assistance of Long-Range Energy Alternatives Planning System (LEAP) software, this paper established the LEAP policy model to explore performances of industry policies formulated...
This article presents a discussion about the issue of soil resource management in the context of sustainable development. These resources are one of the basic resources on Earth, conditioning the sustainable development of present and future generations by providing the capacity for food production. The study contains an indicator-based assessment of changes in available soil resources as a result...
The adsorption potential of native clay and clay composites was investigated for Golden XGL dye removal from aqueous solution in batch and fixed-bed column modes. Morphological structure and functional groups of the adsorbent were determined by Fourier transform infrared spectroscopy analysis. In batch adsorption studies maximum adsorption capacity was determined by optimization of operational parameters,...
Industrial and environmental pollution are sources of cadmium (Cd) exposure that cause serious health hazards. In this work we investigated the protective effect of quercetin on Cd-induced hepatorenal damage in rats. Cd toxicity was confirmed by evaluating its level in serum and tissues. Liver function enzymes, bilirubin, albumin, creatinine, uric acid, and urea were assessed in serum. However, lipid...
This paper focuses on the hierarchical power distribution optimization of multiple local energy network (LEN) systems that are formed in three levels and can be operated in six typical modes. The decentralized optimal model for each LEN (the first level) and LENs (the second level) as well as the concentrated optimal model for the top level of the system are built, respectively. For each LEN, all...
The relationships between species richness and driving factors might vary with taxa and spatial scale. For this study we used plant species data of eight groups from nature reserves in China, namely pteridophytes, gymnosperms, angiosperms, vascular plants, Chinese endemic species, rare and endangered plants, woody plants, and herbaceous plants, and eight putative environmental predictors to explore...
Biological filter (biofilter) technology has developed rapidly and has been extensively employed to remove nitrogen pollutants originating from aquatic environments. Due to the different responses of nitrogen microorganisms to various operating parameters and environmental factors, achieving satisfactory nitrogen removal in biofilters remains a challenge. Hence, this review aims to provide useful...
In mountainous regions, rockfall is a typical geological disaster which might bring immense casualties and economic losses, but also endanger the safety of civil engineering construction. Many tunnels are being built in the southwest of China, thus a comprehensive assessment for rockfall risk is needed. For this purpose, in this paper, based on normal cloud model theory, we created a multi-index evaluation...
