Carbon is still an important source of energy in Europe, covering about one-fourth of electricity production. There are plans to open around 50 new coal-fired power plants. But the continued use of coal has a price, we pay all, mainly with our health can be affected by excessive environmental pollution Today more and more emphasis on the concept of „green economy” that should be reflected in improving people’s lives through effective management of environmental issues and reducing environmental risks Thus, through the present paper we aim to highlight those aspects that would allow the improvement of the environmental performance of coal-fired power plants in Romania by improving the efficiency and effectiveness of the Environmental Management System (EMS) as a component of the Integrated Management System along with the Quality, Health and Safety Management System . We start from the premise that the development and implementation of an effective and efficient environmental management system (EMS) becomes a priority for all companies in the field , especially since their activities based on coal burning , are considered among the most polluting.","PeriodicalId":79497,"journal":{"name":"Immunotechnology : an international journal of immunological engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42171823","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}

Widespread use of substances containing metals inevitably lead to their deposition in soil affecting soil microbiota, which plays important role in maintaining soil functions. The aim of our study was to determine number of heavy metal resistant isolates acquired from the soil from heavy metal polluted area of dump near Hnúšťa. Soil samples were obtained from two collection sites (48° 36 ́ 4,47502 ́ ́ N, 19° 57 ́32,654 ́ ́ E and 48° 36 ́ 4,4634 ́ ́ N, 19° 57 ́ 32,67 ́ ́ E) and mixed together. The microorganisms used in this study were routinely cultivated and screened for resistance to different concentrations of four heavy metals – Zn (2–500 mg/l), Cu, Ni, Pb (all three metals tested at concentrations from 0,5 to 125 mg/l). Very high resistance against Cu, Ni and Pb even at the highest tested concentrations was found at majority of tested bacterial strains. Almost all 89 from 89 isolates show resistance against these metals at tested concentrations. Only in case of Zn we determined the MIC (minimal inhibitory concentration) – 125 mg/l. The results point out very high resistance pattern in soil bacteria.","PeriodicalId":79497,"journal":{"name":"Immunotechnology : an international journal of immunological engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49068015","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}

Červenková","doi":"10.29227/IM-2019-01-05","DOIUrl":"https://doi.org/10.29227/IM-2019-01-05","url":null,"abstract":"The need to treat wastewater in a sustainable way to minimalize contamination and maximize the recovery of nutrients is widely recognized. The focus is mainly on the removal and recovery of nutrients because of eutrophication problems in receiving waters, limitations of mining resources and high costs affiliated with nutrient production. Removal of nutrients is also a growing problem for water authorities, as authorities often tighten standards of discharged waters to avoid unnecessary discharge of nutrients into water bodies. The universally used technologies for nitrogen and phosphorus removal involve biological nitrification and denitrification and metal salt precipitation. However, applying these technologies nutrients are made unrecoverable for fertilizing. Electrodialysis (ED) is a membrane process capable of concentrating and separating ions from wastewater. Thanks to the applied current, the migration of ions occurs, and ions are concentrated in the concentrate solution. Laboratory scale ED showed the potential of nutrient recovery from wastewater sources. In this study, nutrients were recovered in concentrate solution from wastewater sludge liquid discharge by using electrodialysis. Calcium and sodium values in concentrated solution increased 10 times, values of potassium and chloride 5 times. The amount of ammonia nitrogen raised from 60 mg/l to 1700 mg/l. The concentrate enriched by nutrients may be used in further processes, e.g. phosphorus and ammonia nitrogen can be precipitated into the form of struvite.","PeriodicalId":79497,"journal":{"name":"Immunotechnology : an international journal of immunological engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41728301","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}

According to the theory of body objectification (Fredrickson, Roberts, 1997), both forms of gender discrimination can induce attention to one's body and appearance, which ultimately can lead to reduced satisfaction of one's body (Szymanski et al. 2011). Since body dissatisfaction is one of the leading causes of eating disorders (Brechan, Kvalem, 2015; Cruz-Sáez et al. 2018), it is important to have a better understanding of sexual harassment and gender harassment relationship with body objectification and disordered eating behavior. The study aims to assess the relationships between sexual harassment and gender harassment experiences, body-objectification, and disordered eating behavior tendencies. 181 (23 males, 158 females) aged 18-38 (M=24.12) participated in this research. Sexual Harassment Experience Questionnaire (Fitzgerald et al. 1998) was used to measure both Unwanted Sexual Attention (Cronbach α – 0,893) and Quid Pro Quo sexual harassment (Cronbach α – 0,876), and Gender Harassment experience (Cronbach α – 0,868). Objectified Body Consciousness Scale (McKinley et al. 1996) was used to measure body objectification: Body Shame (Cronbach α – 0,825) and Body Surveillance (Cronbach α – 0,804).  The Eating Attitudes Test (Garner et al. 1979) was used to evaluate disordered eating behavior tendencies: Dieting (Cronbach α – 0,924), Bulimia and Food Preoccupation (Cronbach α – 0,725) and Oral Control (Cronbach α – 0,714). The results revealed significant sexual harassment and gender harassment experience differences between genders showing that women report significantly higher results of all forms of sexual harassment and gender harassment than men. Data analysis also revealed a statistically significant relationship between higher results of sexual harassment, gender harassment experience, and more pronounced disordered eating tendencies and higher body objectification. Data analysis has shown that gender harassment experience is a significant prognostic factor for higher body surveillance and body shame results, more frequent dieting.","PeriodicalId":79497,"journal":{"name":"Immunotechnology : an international journal of immunological engineering","volume":"92 1","pages":"8-27"},"PeriodicalIF":0.0,"publicationDate":"2021-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48395452","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}
