The objective is to advance the knowledge on the current status of marine plastic pollution in the Gulf of Gabes area of the Mediterranean Sea, by quantifying and qualifying the microplastics in water and biota samples. The results obtained show a high abundance of microplastics in all marine compartments studied with an average abundance of 1.16 items/m3 ± 0.83 SD in the water sample. This concentration is relatively high compared to those reported in other Mediterranean regions. Dominance in number of fragments over other shapes of microplastics was reported in all sites. Polyethylene was the main plastic polymer for water samples (73% of the items analyzed are Polyethylene). These data underscore that the Gulf of Gabes region is a hotspot for plastic pollution, and this calls urgently for precautionary measures. Concerning the ingestion of microplastics by marine organisms, one blue plastic particle of 0.13 mm was found in 20 tested fishes. In addition, ecotoxicological tests were run in order to verify whether 1-4 and 20-25 μm polyethylene beads are likely to trigger lethal and sub-lethal responses in marine planktonic crustaceans and the results show that microplastics were accumulated in crustaceans, and may affect mortality.","PeriodicalId":31081,"journal":{"name":"Lebanese Science Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43535508","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 first two groups of 36 plants each are fertilized according to the recipes recommended by two companies (A and B), treatments 1 and 2 respectively. The third is fertilized according to the conventional method in the soil adopted by farmers (group C). Company A applies standard fertilizer application protocol throughout the life of the plant with a stable pH and electro conductivity of 6 and 2.8 mS / cm respectively. Company B applies an upward fertilizer scheme during the plant's production cycle with a stable pH of 5.6, but an electro conductivity that varies from 2.1 mS / cm at the vegetative phase to 2.5 mS / cm from the appearance of the 1st fruit. Despite its high investment, the two hydroponic treatments T1 and T2 showed greater plant size (127 cm and 129 cm respectively at the 12th week), more fruits (15 fruits per plant each week, compared to 8 fruits per plant in the soil), and higher yield (average mass per plant reached a maximum value at the 11th week of 1.192 g for T1 and 1,189 g for T2 compared to 499 g for the soil). The difference in revenues shows a negligible financial advantage in favor of Company B. Adopting fertilization recipe of Company A or B is not a limiting factor at the financial level hence either one of the two formulations is adequate.","PeriodicalId":31081,"journal":{"name":"Lebanese Science Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46474425","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}

Due to their supposed role in public debate as well as persuasion and promotion of opinions and new behaviours among users of such networks, they are called Influences. In the last few decades, communication research has explored opinion leaders as effective influences on their environments and societies. They present and interpret information, give opinions and adopt innovation before the audience, in addition to mediating between the audience and media in the communication process. More particularly, Facebook represents a new space for discussion in the Arab World. The phenomenon spread during the Arab Spring in 2011 and even expanded later. It took different forms, like the transfer of information, interpretation of incidents, and mobilization for mass events, political and cultural polarization and new critical discourse. However, what is taking place in cyberspace is still debatable. The present study looks into the new opinion leaders’ phenomenon in the Arab public sphere and their part in political and religious polarization. The discourse of posts on three Facebook accounts of new opinion leaders (Influences) in Jordan is analysed. As these figures play disparate roles in national political and cultural events and dilemmas, lessons can be derived from such a rising phenomenon. The study aims at exploring the discourse features of the posts addressing public issues which sparked widespread controversies in the period 2017-2018, such as the civil state, theocratic state, school curriculum reform and political reform in Jordan. Study has found that the new opinion leaders’ phenomenon on social media in Jordan is on the rise, in terms of political and religious polarization. That would reveal some characteristics and roles of new opinion leaders, in addition to the features of their discourse with reference to major political and religious issues and values as well as political and religious polarization.","PeriodicalId":31081,"journal":{"name":"Lebanese Science Journal","volume":"8 24","pages":"211-229"},"PeriodicalIF":0.0,"publicationDate":"2020-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41308480","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}
