[{"id":1031,"title":"A mobile app to promote self-limiting Carbon emissions and improve the rationality of choices among the students.","sha":"00532261a308bc92f5b9ab5a0054608d","user_id":null,"state":"published","body":"Global warming has increased due to accumulation of Carbon Dioxide, creating serious impacts on the existence of humans and their activities. The learning- teaching efficiency is also impacted by higher temperatures. The educational institutes also have contributed to the global warming by little quantities due to their activities and energy use. Thus, they have a role to promote the self-limiting Carbon emissions of their main stakeholders. As a practical method to promote self-limiting among students, a mobile app can be introduced via educational institutes which will add points upon the choices, i.e. demand e-books, attending virtual conferences, use a bicycle instead of the school bus. In here, the average Carbon emission level per student, maximum Carbon emission allowance per student and average Carbon emission per different activity are needed to be calculated first. The points can be allocated as per the scale of reduction due to the selected activities via an algorithm. Further, similar algorithms can be used to show the best options to be within the permitted limits. The earned points can be used to offer rewards, assign marks for some fundamental requirements, i.e. ethical behaviour, rationality assessments or exchange with  money  to make the use as a habit.","created_at":"2022-12-04T16:33:52.535Z","updated_at":"2023-01-16T06:00:18.051Z","zenodo_id":7539340,"doi":"https://doi.org/10.5281/zenodo.7539340","subject":null,"tags":["global warming","carbon emissions","self - limiting","greenhouse gas emissions","higher education and carbon emissions"],"vote_count":0,"view_count":1,"score":0.1,"deleted":false,"muted":false,"tweeted":false,"attachment_file_name":null,"attachment_content_type":null,"attachment_file_size":null,"attachment_updated_at":null},{"id":415,"title":"Operational and lifecycle advantages of hybridized iron ore reduction and biomass gasification","sha":"d579f9e2301065453dde71408f1be61c","user_id":null,"state":"published","body":"Recent research has demonstrated that biomass can be used as a reducing agent for iron ore but also that iron ore reduction can be coupled with biomass gasification, co-producing reduced iron and synthesis gas which can itself be converted to liquid fuels through the Fischer Tropsch process. \r\nEconomic analysis has revealed that iron is the preferred product from a financial standpoint and that such processes will tend to focus on producing iron, with a trade-off in terms of synthesis gas production. However, critical operational considerations have yet to be considered. An iron smelter's design capacity is constant but the productivity of an iron mine is initially far below that capacity, taking years to reach full capacity, fluctuating over the course of its lifespan and then diminishing to nothing when the iron deposit is depleted. Co-production permits this operational deficit to be met with increased gasification and allows for conversion to dedicated gasification after the mine's lifespan. \r\nBesides offering a carbon-neutral alternative to coal for iron smelting, this technology therefore offers a means of increasing smelter productivity and a pathway toward a renewable fuels industry, with the capital expenses covered by the iron smelting phase of operation.","created_at":"2017-10-18T08:54:54.610Z","updated_at":"2017-10-19T06:00:33.311Z","zenodo_id":1018918,"doi":"https://doi.org/10.5281/zenodo.1018918","subject":null,"tags":["renewability","carbon emissions","engineering"],"vote_count":0,"view_count":1,"score":0.1,"deleted":false,"muted":false,"tweeted":true,"attachment_file_name":null,"attachment_content_type":null,"attachment_file_size":null,"attachment_updated_at":null}]
