This study uses the social network analysis methodology, applied to bibliometric authorship for VI research, to discover trends in collaboration, identify lead scientists, organisations, and countries. Furthermore, some of the external factors influencing the collaboration and productivity were assessed. The data suggests that the global research network for VI produced over a time span of 54 years 566 publications via 157 sources. The research network is composed of 437 organisations and 1053 authors from 33 countries. This suggests an increasingly active international collaborative research effort. However, inter-continental cooperation is much less than continental. The top five most central countries in the network are the USA, followed by Canada, China, The Netherlands, and Italy. The researchers with the most publications are from these five countries as well as the top organisations. The social network analysis conducted shows a good approximation of the collaborative structure for the key countries, organisations and researchers involved. Since 2010, the research community has become more stable.","PeriodicalId":11724,"journal":{"name":"Environment and Pollution","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79936620","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}

{"title":"Seedling and Adult Plant Resistance in the Ethiopian Bread Wheat Landraces to Stripe Rust Disease","authors":"F. Yirga, A. Badebo, M. Dejene","doi":"10.5539/EP.V10N1P57","DOIUrl":"https://doi.org/10.5539/EP.V10N1P57","url":null,"abstract":"High yielding farmers’ bread wheat cultivars are threatened by emerging race(s) of stripe (yellow) rust caused by Puccinia striiformis f.sp. tritici (Pst) in the highlands of Ethiopia. In depletion of rust resistance in commercial cultivars, researchers often look for new sources from close relatives and landraces. The objective of this study was to determine stripe rust resistance in selected Ethiopian bread wheat landraces obtained from the Ethiopian Institute of Biodiversity (IBCE). In 2017, a total of 152 accessions were exposed to the prevailing stripe rust races in hot spot areas (Kulumsa and Meraro) in Arsi zone of Oromia region. In the second year (2018), only promising landraces (57) were evaluated both at seedling and adult plant growth stages. The seedling test was conducted in the greenhouse at Kulumsa research center using three (PstS2 (v32), (PstS11) and (PstS11 v25) Pst races. In field evaluations, terminal severity (TRS), coefficient of infection (CI), area under disease progress curve (AUDPC), disease progress rate (DPR) and head infection (HI) were considred. High disease pressure was noted with 100% severity on susceptible entries at both locations and seasons. Highly significant (P<0.001) differences were noted among the landraces for all disease parameters indicated above. Of the 152 landraces, 57(38%) exhibited lower or equal disease reaction compared to the resistant check(Enkoy) across locations. Overall, 18 accessions showed resistance to the prevailing Pst races both at seedling stage and field conditions whereas14 exhibited susceptible /intermediate reaction at seedling stage, but had lower disease reaction under field conditions. This study has identified potential sources of overall and adult plant resistance in the Ethiopian bread wheat landraces to the prevailing Pst races. The authors recommend further studies to determine the diversity and/or novelity of resistance genes in selected accessions. Future wheat improvement should focus on utilization of these genetic resources to minimize the re-current outbreak of rust diseases.","PeriodicalId":11724,"journal":{"name":"Environment and Pollution","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82268104","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}

Also, the majority of the respondents preferred non-monetary incentives as an effective strategy to motivate individuals to improve the accuracy of waste sorting. Then the participants are given nine strategies as separate behavioural nudges to improve the waste sorting behavior. The responses are highly varied and the majority prefer to use a combination of different colours and detailed labels as a motivational strategy. Thus, the preferred strategy was examined at the faculty premises throughout three stages and tested three hypotheses.

So, examine people's attitudes and a reaction to smog is theoretically and realistically meaningful. Recent projects of coal as a source of energy, high rates of outpouring from unmonitored industries, a large number of automobiles on roads, play a major role in trends of deforestation to construct new roads and recently the burning of crops leftovers has added fuel to the fire. Vehicles increase by 9% compared to the last five years due to a lack of public transport systems.

Batch adsorption were performed and pH (3.0, 4.0, 6.0, 9.0, 11.5), adsorbent dosage (0.1, 0.2, 0.3, 0.4, 0.5 g), contact time (10, 20, 30, 40, 50, 60 minutes) and initial concentration (25, 50, 100, 125, 250 mg/L) were optimized for Indigo dye using the adsorbents.

The concentrations of nine micronutrients, Sodium (Na), Magnesium (Mg), Chlorine (Cl), Potassium (K), Calcium (Ca), Vanadium (V), Manganese (Mn), Copper (Cu) and Iodine (I), in polished Jasmine 85 rice, locally cultivated in five rice farming areas in Ghana (Afienya, Afife, Dawhenya, Ashaiman and Aveyime), were determined using Neutron Activation Analysis. The standard materials used as reference were the International Atomic Energy Agency (IAEA)-530 Tuna fish homogenate and the National Institute of Standard and Technology (NIST) USA 1566b Oyster Tissue. Recoveries of the elemental concentrations ranged from 88% to 111% of the certified values. Relative standardization method was used in the quantification of the elements. The range of concentrations measured in the rice are: 142.3-188.1 mg/kg for Na, 483.2-875.7 mg/kg for Mg, 465.6-718.0 mg/kg for Cl, 514.62949.0 mg/kg for K, 2303.0-2622.0 mg/kg for Ca, 0.0698-0.1925 mg/kg for V, 9.956-14.460 mg/kg for Mn, 0.8728-1.6790 mg/kg for Cu and 0.1181-0.1447 mg/kg for I. Using Hierarchical clustering analysis and Principal Component Analysis to evaluate the intensities of measured concentrations, K was established to be the most abundant, and was used to categorize two distinct clusters; Group 1 farms (Ashaiman, Afienya, and Dawhenya) and Group 2 farms (Aveyime and Afife). Group 2 farms recorded elevated intensities of micronutrients. With Pearson's correlation coefficient, some noteworthy correlations realized were between Na and K (r = 0.951), Na and V (r = 0.842) and K and V (r = 0.812). This indicated the same or similar source inputs for each pair. The calculated mean daily intake of K exceeded the mean Recommended Dietary Allowable and Adequate Intake for all Life Stage Groups. Estimated health risk associated with the consumption of rice was only present for children between the ages of 1 and 3 for Mg. The information on these nine micronutrients content of the rice from these five farming areas would be valuable in rice consumption studies to evaluate the overall availability of micronutrients to the Ghanaian populace and age groups and also in nutrition planning for analysis of nationwide rice supplies, mainly for regions and countries known to be susceptible to deficiencies of these micronutrients. The techniques espoused in this research can be used to accurately determine the concentration of micronutrients in rice and also trace the area where the rice was produced.","PeriodicalId":11724,"journal":{"name":"Environment and Pollution","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89217351","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}
