The studies of the storage methods of planting material and their effect on the survival rate of cuttings and shoots were carried out in the years of 2019–2021 in the experimental field of the Institute of bio-energy crops and sugar beets, Ukraine. Two willow (Salix spp.) species: three-stamina variety Panfilivska and common willow variety Zbruch, were studied. Rot-affected cuttings and shoots as well as the number of the sprouted ones were monitored during the period of their placing in the storage till their planting in the field. It was found that both cuttings and shoots stored well in all treatments. During the storage, a small number of sprouted cuttings and disease affected ones were recorded. Rot-affected cuttings and shoots of both varieties were recorded only when they were stored in plastic bags both with and without lime treatment of incisions. Rotaffected planting material was not recorded when other storage methods were used. It was established that during the storage moisture losses in cuttings and shoots of both varieties were not seen on any record date and as far as the content of nutrition elements (NPK) is concerned, there was a decreasing tendency. It was found that the survival rate of planting material depended on both variety peculiarities and its species, and it was high even on the first record date. Common willow variety Zbruch had the highest percentage of survival rate of cuttings and shoots as compared with the three-stamina variety Panfilivska. All storage methods of cuttings and shoots at air temperature 3–5°C ensure their good shelf-life with small damages caused by disease and slight germination in some years. The survival rate of planting material depended on both varietal peculiarities and its species. The highest percentage of survival rate of cuttings and shoots was typical for common willow variety Zbruch as compared with three-stamina variety Panfilivska.","PeriodicalId":52648,"journal":{"name":"Ecological Engineering Environmental Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47851332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper develops an algorithm for a selected industrial electric vehicle to be controlled at different speeds that envisages working on real time Internet of Things (IoT) based Global Positioning System (GPS) signals. It engages the ARM core based STM micro-controller in conjunction with mesh networked Bluetooth Low Energy (BLE) to govern the operations besides enabling it to be dynamically monitored. The system design considers the vehicle parameters that include the speed of vehicle and the engine, State of Charge (SoC) and State of Health (SoH) of battery together with real time GPS based navigation system using IoT bundled GPS based maps interface. The methodology involves a closed loop monitoring with specified sequence of steps that augur the system to operate at defined speed over designated work shifts and schedules. The procedure introduces an embedded C environment with a process of unit-testing based simulation to capture the merits of schema in terms of an improved vehicle performance under varying parametric conditions.","PeriodicalId":52648,"journal":{"name":"Ecological Engineering Environmental Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46207387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The selection was made from a “battery of bioassays”, which necessarily includes the D. magna mortality test. The rest of the methods for comparing sensitivity were selected situationally. The algorithm was tested on model samples. It was found that mortality tests for D. magna and C. affinis are the most sensitive to contamination with mineral nitrogen compounds. E. coli bioluminescence reduction test is preferred when there is contamination with Cu, phosphates and pyrophosphates. It was shown that the test to reduce the chemotactic reaction of P. caudatum should be used when the aquatic environment is polluted with Cd, Pb, Zn, oil products, organic herbicides imazethapyr and imazamox. The proposed algorithm is universal, but it should be applied when the priority pollutant is known, the effects of which prevail over the action of other compounds in the sample.","PeriodicalId":52648,"journal":{"name":"Ecological Engineering Environmental Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47948855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was conducted to test the impact of tillage (conventional (CT) and no-till (NT)), residues (vetch (C1) and uncover soil (C0)), and three nitrogen (N) fertilization rates (30, 60, and 90 N kg ha -1) on soil organic carbon (SOC), total nitrogen (N), C/N ratio, soft wheat yields and SQ. The experiment was established in 2010 in the Moroccan semi-arid. After ten years, the SOC concentration was greater under NT (9.4 g/kg) compared to CT (8.4 g/kg). Crop residues also enhanced SOC (10 g/kg) contrary to C0 (8.1 g/kg). Application of N fertilization showed profound effects on total N, increasing levels of N fertilization led to higher total N irrespective of tillage. Crop residues increased total N (0.6 g/kg) better than C0 plots at the horizon 20–40 cm. Soft wheat revealed an improvement under NT (4213.8 kg ha-1) versus CT (3785.6 kg ha-1) and it responded positively to the N application. For SQ evaluation through the indexing methods (SQI), principal component analysis was done for eight soil indicators to select the minimum data set (MDS), which were subsequently normalized and integrated into the SQI, additive (SQIANL), and weighted (SQIWNL). NT revealed higher scores (0.52; 0.6) than the CT (0.46; 0.53) for SQIANL and SQIWNL, respectively, at the horizon 0–20 cm. the residues layer on the soil surface improved SQIWNL score (0.59) compared to C0 (0.55). Moreover, the correlation (r) with yield and the sensitivity (S), allowed us to choose SQIWNL, as the best index (highest r and S) to evaluate SQ under different practices studied. Indeed, SQIWNL revealed an intermediate SQ under NT and at C1treatments, compared to CT and C0 (low SQ).","PeriodicalId":52648,"journal":{"name":"Ecological Engineering Environmental Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45422621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Ukraine, up to 80% of surface water bodies, according to official data, are unsuitable as sources of drinking water. A significant part of groundwater is supplied to consumers with significant deviations from quality standards. The urgency of the work is due to the need to assess the physiological value of the mineral composition of drinking water in some regions of Ukraine, in particular the content of fluoride in surface and groundwater sources. The paper evaluated the level of fluoride balance as a possible factor influencing the health of the population of certain regions of Ukraine. In Ukraine, there are four main geochemical regions in terms of fluoride content in drinking water (from very low concentrations of fluoride to high content). On the example of Odessa and Poltava regions, it was noted that the foci of endemic pathology are usually concentrated in the area of development of adverse natural or man-made processes. Both deficiency and excess of fluorides are important factors in shaping the health of the population, which determines the rationale for fluoridation or fluoridation of drinking water. Depending on the components of the environmental risk of high or low fluoride content, comprehensive caries and fluorosis prevention schemes were also recommended.","PeriodicalId":52648,"journal":{"name":"Ecological Engineering Environmental Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43809803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper discusses the main methods of removal of nutrients from wastewater, as well as presents promising technologies and techniques. It contains the recommendations for optimal conditions for the precipitation of ammonia nitrogen from an ion exchange regenerator for further use as an ammonium fertilizer. The maximum efficiency of ammonium nitrogen removal was established. According to the results of the best options, the deposition of real ion exchange concentrates was carried out. The humidity level was set during the drying of mineral fertilizers. The moisture content determined the content of sediment, which is close to the number of water molecules to the formula of the fertilizer MgNH4PO4 ∙ 5H2O. Complex phosphate fertilizer struvite was characterized. A comparative agronomic evaluation of synthetic struvite was performed. The influence of struvite on the processes of germination of cultivated plants was carried out. The results show that the method of obtaining struvite does not significantly affect the processes of wheat germination, and the determining factor in the effectiveness of fertilizers is the method of its application and dosage.","PeriodicalId":52648,"journal":{"name":"Ecological Engineering Environmental Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45910674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The date palm empty fruit bunch is a lignocellulosic waste that takes more time for degradation and has a low biodegradability, thus pretreatment is needed to improve anaerobic biodegradation. In this study, the substrate was pretreated with different ratios of alkali-NaOH: 6, 18 and 30% (w/w) (ratio weight of NaOH / weight of Volatile Solid) for 10 min at room temperature to evaluate the effect of high alkali concentration on the methane potential and biodegradability. The experiment was conducted in a 5 L batch reactor under mesophilic conditions (37 °C). The methane potential of the untreated substrate was 98.5 N mL/gVS. The best methane potential improvement of 104% was achieved in the treatment of 18% (w/w) (204 N mL/gVS) with a biodegradability of 50%. Besides, two kinetic models were used to fit the experimental methane potentials and to explore process parameters (Modified Gompertz and Transference function).
