This work is in this theme. Indeed, the objective of this study is the determination of the impact of some heavy metals on the quality of water resources generated by the discharges of some industrial units in the region of El-Kalitoussa. The results obtained have identified the real threat of industrial pollution on the receiving environment (wells, boreholes and lake). However, the state of contamination of groundwater by heavy metals has been achieved by processing analytical results according to a methodology mono and bidimensional using computer tools. This metallic pollution is highlighted by an abnormally high average content in the majority of the analyzed water points for iron, lead and nickel. While copper has an average concentration at the tolerance limit. However, the highest concentrations of heavy metals measured show that the closer the wells and boreholes are to industrial waste, the more vulnerable they become to possible contamination.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70911025","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}

This phenomenon takes place independently and cannot be easily stopped by legislative measures, as it is known that the restoration of structural imbalances in relation to age requires a long time. In Romania, the transformations that took place after 1989, in the political and economic system, in the social life, as well as in the mentality of the people, brought about important demographic changes. Therefore, the number of the population continuously decreased year by year, the demographic ageing along with the decrease of the birth rate and the increase of the number of emigrants being the main demographic phenomena that made their presence felt. These phenomena have manifested themselves mainly in rural areas. This paper aims to highlight the scale of the demographic ageing process in the rural areas of the North-East Region and to assess its socio-economic consequences in the medium and long term.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70911842","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}

Substantial studies have been conducted on the subjects related with sustainability after 1980s. Increasing interest in sustainability concept has also enhanced point of view from every angle. The preliminary studies on the subject were mostly on comprehension of environmental sustainability. Over the time, sustainability has become privileged research domain in every angle from economy to health, from agriculture to management and so on. In Turkey, there have been various researches on sustainability and postgraduate level theses have been published. The objective of the present study is to a nalyze postgraduate theses on “sustainable development” in Turkey. Thus, it was aimed to determine which dimensions and which angles of sustainable development have been covered so far in Turkey. In this scope, postgraduate theses located in the database of the Higher Education Board National Thesis Center (YÖKTEZ) were screened through a literature search; then, collected data was classified through content analysis; and finally, bibliometric analysis was conducted. Totally 250 postgraduate theses on sustainable development published in the period of 1992-2021 were collected. The bibliometric analysis was conducted on collected theses with respect to their type, publishing year, language, distribution according to university and institute, titles of thesis advisor, number of pages, references, keywords, research method and data collection method. As a result of our analysis, it was determined that theses on sustainable development were oriented on environment, environmental issues, environmental sustainability, climate change, sustainable development education, renewable energy and sustainable economy subjects. Moreover, theses were predominantly master theses and issued by students registered with postgraduate programs of Social Science Institute. Although number of theses has varied over the time, it increased significantly recently. It was also determined that they were suffering major deficiencies with research method and0 data collection methods.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70912035","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 in southeastern part of Romania, an area with a share of approximately 19.2% of the total cultivated national area, in Ialomița, Călărași, Brăila, Tulcea and Constanța counties. The main purpose of the research was to evaluate the degree of zinc supply of the soils, and the nutritional status of maize plants with this microelement, for which, soil samples were taken from a depth of 0-20 cm and samples of plant in the phenophase of 4-7 leaves. The methodology for evaluating zinc regime consisted in determining the content of mobile Zn in soil, soluble in CH 3 COONH 4 -EDTA solution at pH 7; values calculation of the reaction-mobile phosphates index (RMPI) and the zinc deficiency index (ZnDI), in order to establish probability classes for zinc deficiency occurrence. Results shows that of total analyzed samples (92), depending the content of mobile Zn by probability classes, 43% samples belonged to high probability class, 33% to medium probability class and 24% to low probability class, until improbable. Regarding percentage values of reaction-mobile phosphates index (RMPI), showed a distribution of soil samples, according to the probability class by zinc deficiency occurrence, of 68% for samples with high and very high probability, 22% for low probability and 10% improbable. Finally, the probability of this phenomenon occurrence, assessed by the zinc deficiency index (ZnDI), led to a distribution of percentage values as follows: 54% high and very high probability class, 21% medium probability class, 12% low probability class and 13% improbable class. The results obtained regarding the soils classification in probability classes of Zn deficiency occurrence in maize crop, provides precise information to stakeholders for the implementation of technological solutions to prevent this phenomenon that can cause significant production losses.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70912281","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}

Several factors influenced the expansion of these cities, each with a different intensity and impact. Based on the historical context, port cities have experienced both times of evolution and periods of decline. This paper aims to analyze two port cities in Romania by highlighting the role of ports and related activities in the economic development of cities. The port cities of Galați and Brăila were chosen as case studies; in these cities, the role played by their ports as engines of development in the two cities was investigated. The analysis revealed that after 1990, the change of political regime and transition to an open market economy affected the economic situation in the two cities studied. Nowadays, ports have much smaller importance in the economies of both studied cities. This research is important as a starting point for understanding the current issues of the two cities and finding potential solutions.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70912062","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}

These forests have economic, social, and ecological functions. The research was realized in urban forests from Brasov city. The favorability of certain orographic and edaphic factors were determined for the selected species (by using these property values and sheets regarding the species ecological requirements (Norway spruce, silver fir, beech and sycamore). If we consider the ecological requirements of the main species that comprise the studied stands and a series of orographic (altitude) and edaphic factors (reaction, base saturation degree, edaphic volume, potential global trophicity), we were able to calculated the favorability of species based on grades. The conclusion was that Norway spruce has the highest favorability, followed by common beech. Even though silver fir has a lower favorability then Norway spruce, all plots have fir and Norway spruce in their composition. Furthermore, it can be observed that a higher favorability, as in the case of sycamore, does not necessarily determine its presence in more areas. On the contrary, sycamore appears only in a very low number of plots.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70910658","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}

Therefore, noise levels were assessed in four different schools in Jalingo, the capital of Taraba State using a Lutron sound level meter, model SL – 4030. The aim of the study was to compare noise levels in the schools with the limits recommended by WHO and ISO, so as to make appropriate recommendations in case of undesirable results. The ANOVA statistical tool was used to demonstrate that the noise levels differ in the classrooms and the Least Significant Difference (LSD) statistics was used to show the significance of the variation of noise levels in the classrooms as suggested by the ANOVA. The mean equivalent noise levels (Leq (dB(A)) varied considerably above WHO recommended limits in classrooms. In the classrooms across all the schools, noise levels were within satisfactory range (61 – 75 dB(A)). This range however, exceeds the recommended noise limits in classrooms (35 – 55 dB(A)). Meanwhile, the control sample locations had mean noise level within the good range (41 – 60 dB(A)). It was also observed that at the control sites, mean noise levels were within the range recommended for classrooms during lessons. Higher noise levels than the endorsed limits by the WHO in the classrooms across all the schools are justifiable by so many factors such as: proximity to busy roads, students – Teacher’s activities and perhaps some acoustical reasons. Interestingly, the control of noise pollution in these schools to meet the international recommended standards is much possible if the recommendations from this study are obeyed.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70911950","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 main objective of this study was to analyze the minimum air temperatures and highlight their extreme values over the 1980-2015 period . The climatic data were collected from the Brașo v-Ghimbav meteorological station and a set of specific indices, generically called as indices of extremes and climate change by the WMO’s Expert Team on Climate Change Detection and Indices (ETCCDI), were subsequently calculated. The resulting quantitative assessments of minimum air-temperature variations in the above mentioned area has also proved that they can be useful tools in calculating other derived technical parameters which may be relevant for the design and onset of heating or cooling installations, in order to maintain a comfortable indoor climate in residential buildings.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70912099","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}
