Newly hatched Drosophila melanogaster larvae of the same age and adult individuals were used. While the individuals in the control group were tested in standard media, the individuals in the experimental group were tested under 3 different conditions at the rates of 25%, 50%, and 100% of each water sample. The effects of polar water added to the media on mortality rates on Drosophila melanogaster eggs, larvae, and adults were investigated. The effect of water samples collected from Ardley and Horseshoe Islands on the survival percentage in Drosophila melanogaster larvae was found to be similar to the control group. Furthermore, while the viability rate in Ardley and Horseshoe Island was 92% and 96%, respectively, in the control group individuals, similar results were obtained in all rates in the experimental group. The water samples obtained from 3 different points from the Antarctic region have not reached a level that will adversely affect the lives of the larvae and adults of the creature as of the present day. Nevertheless, although pollution was detected in some areas in the Antarctic region in the literature, we consider that this pollution can be prevented before it reaches dangerous levels with some measures to be taken.","PeriodicalId":287513,"journal":{"name":"International Journal of Science Letters","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130708836","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}

For this purpose, two different dyestuff extracts, red and blue are gained from its roots with acetone and ethanol solvents, as well. Wool fabrics (194 pieces) dyed with AIK(SO4)·12H2O, FeSO4·7H2O, CuSO4·5H2O, AgNO3 and CoCI2·6H2O mordants at pH 2, 4, 6 and 8, respectively. Unmordanting, pre-mordanting, meta-mordanting, and post-mordanting methods were used for the dyeing experiments. In addition, wool fabrics were pretreated with artificial animal urine system (AAUS) including NH3 (3%, v/v), CaC2O4 (3%, m/v) and urea (3%, m/v) before dyeing processes in order to see the improvement in the fastness properties of the dyed samples with meta-mordanting method. The color codes were determined with Pantone Color Guide, and also washing-, rubbing fastness levels were evaluated using gray scale. According to the evaluations, it is observed that AAUS mordant system helps to improve the light fastness values in general. Good results were obtained both for the dyeings with red and blue components, as well. Optimum dyeing parameters were also evaluated for wool fabric in terms of usage in textile industry.","PeriodicalId":287513,"journal":{"name":"International Journal of Science Letters","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133252805","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}

Activated carbon, which has started to be used in many fields in recent years, is observed to be preferred as an important additive in the food industry. This study aimed to investigate the reliability of the use of activated carbon as a food additive in different model organisms, such as Drosophila melanogaster , Artemia salina , and Daphnia magna . To this end, the organisms were kept alive in nutrient media containing activated carbon at different concentrations (0.1 mgmL -1 , 0.5 mgmL -1 , 1 mgmL -1 , 2.5 mgmL -1 , and 5 mgmL -1 ), and changes that occurred in their percentage of survival were determined for 48 h. According to the data obtained, for all three organisms, it was found that in comparison with the control group, there was no decrease in survival percentages in any of the experimental groups in which activated carbon was used. On the contrary, there were increases depending on concentration. Especially in A.salina, the percentage of survival, which was 78 % in the control group, increased up to 87 % (P <0.05). As a result of the study, it was concluded that activated carbon at the specified doses might be used reliably as a food additive. It was evaluated that these results should be supported by in vivo and in vitro studies to be conducted in different organisms.","PeriodicalId":287513,"journal":{"name":"International Journal of Science Letters","volume":"38 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130734641","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}
