For this reason, understanding its growth dynamics falls within the criteria of forest and peri-urban sustainability. The effects of soil condition on the survival and growth of Robinia pseudoacacia planted on degraded and cultivated land, respectively in Monte Romano site and Azienda Agraria didattico-sperimentale “Nello Lupori” site, in Italy, were studied in a field transplant experiment using the analysis of variance. Cultivated land showed higher survival rate because of the better soil, topography and climatic conditions. Height and diameter growth responded differently to soil conditions and monitoring period. Mean height and diameter increases were higher in cultivated land. A significant difference in height was found between the initial and final periods in cultivated land. This study is considered important because the selected species can help improving the soil conditions of the selected site so in the future this area can be reforested with valuable wood species. This has to be taken into consideration especially for Albania when illegal logging has created a strong decrease of forest surface associated with soil erosion phenomenon, overflooding, as well as overuse of the forest for firewood to fulfill the people demand, especially in rural areas. In addition, honey production is an important agroforestry aspect and the flowers of Robinia pseudoacacia are known for the production of good quality honey; moreover they can be used as medicinal plants.","PeriodicalId":52648,"journal":{"name":"Ecological Engineering Environmental Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42470479","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}

Cheapness and availability of the raw material (the natural zeolite, clinoptilolite from Dzegvi and Tedzami mines is used as a substrate and seawater – as a source of potassium ions) make this method very interesting and prospective for the countries with clinoptilolite stocks, located in the seaside regions and engaged in agrarian industry (Georgia, Greece, Romania, Bulgaria). It includes two technological processes: sorption and membranes ones. At the first stage, for intensification purpose electrodialysis was used for concentration of sea water. The optimal parameters for concentration of sea water were matched using the electrodialysis apparatus produced in the Institute workshop. In the produced concentrate of sea water, the index of potassium-ion concentration exceeds 4, being twice higher than the natrium-ion concentration index. At the second stage, selection of sea water ions was provided on the natural zeolite by so called dual-temperature ion exchange method: during sorption of potassium by clinoptilolite at low temperature the other ions pass into filtrate. The received potassium-enriched zeolite is a new type fertilizer: potassium containing therein passes into soil “as needed”, when soil is impoverished.","PeriodicalId":52648,"journal":{"name":"Ecological Engineering Environmental Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41681690","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}

Encourages the creation of new materials. In order to reduce the weight of aircraft structures, for example, multi-layer structures that combine lightness, rigidity, and strength are used. For many areas of technology is necessary such that combine structural strength with high electrical, thermal, optical, and other properties. Regulating the structure of traditional materials is a promising way to improve quality. Thus, by means of directed crystallization of steels and alloys, cast parts are obtained, for example, gas turbine blades, consisting of crystals oriented relative to the main stresses in such a way that the edges of the grains are unobtrusive. Directional crystallization allows increasing plasticity and durability several times. The greatest environmental pollution occurs in the area of airports (airfields) during the landing and take-off of aircraft, as well as the warming up of their engines. When engines are running on take-off and landing, the maximum amount of carbon monoxide and hydrocarbon compounds enter the surrounding environment, and the maximum amount of nitrogen oxides enter the flight process. A jetliner that makes a transatlantic flight requires from 50 to 100 tons of this gas. On the territory of the airfield, engines are launched, taxiing, take-off, and landing of aircraft, during which harmful exhaust products of aviation engines, pre-launch (waiting location) and on the runway enter the atmosphere.","PeriodicalId":52648,"journal":{"name":"Ecological Engineering Environmental Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47520153","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}

Tsenzhiv of Yamnytsya territorial community of Ivano-Frankivsk region on sod-podzolic degraded soils according to the generally accepted research methods. The productivity of miscanthus and switchgrass depends on the biometric indicators of plants, namely the height of plants and the number of stems. Correct models of miscanthus and switchgrass productivity are calculated depending on the dose of sewage sludge. For miscanthus, the correlation coefficient r = 0.952 and for switchgrass r = 0.951, which indicates a high linear relationship between plant height, number of stems and productivity. The dry matter yield in grass energy crops varies according to fertilizer application. The productivity of the agrophytocenosis of miscanthus is much higher than that of switchgrass. With the addition of sewage sludge at a dose of 40 t/ha, the dry matter yield under the same growing conditions in the agrophytocenosis of miscanthus is 12.2 t/ha, or 3.3 t/ha higher than the productivity of agrophytocenosis switchgrass. The use of composts based on SS + straw (3: 1)) – 30 t/ha + N30K55, has a significant impact on yield, providing the highest productivity of miscanthus – 13.0 t/ha, and switchgrass – 9.6 t/ha. In order to obtain stable biomass productivity of grass energy crops (miscanthus and switchgrass), it is advisable to use compost of sewage sludge and straw in a ratio of 3: 1 at a dose of 30 t/ha. Thus, two important problems are partially solved, namely increasing the productivity of energy crops and utilizing municipal waste (sewage sludge).","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":"42415373","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}
