Hydrogel swelling and nutrient release data were obtained over time at varying temperatures and pH conditions. The experimental data were fit into the power law, Tsai and Strieder, and Johansson’s models to determine the kinetic parameters for the swelling behavior and nutrient release. Under the experimental swelling conditions, the maximum and minimum swelling capacities of the hydrogel blend were 322.9245% and 228.0483%, respectively. The data fit to the power law suggested that a pseudo Fickian behavior describes the diffusion mechanism. The data fit to the Tsai and Strieder and Johansson’s models provided the experimental values for the α and temperature correlation as 3.69×10-5 and 0.0278, respectively, which implies that the diffusion behavior within the hydrogel does not vary significantly within the temperature range. Lastly, the inconsistency observed in the nutrient release behaviors at varying pH suggested that additional trials may be required in order to establish a clearer relation between pH and nutrient release behavior.","PeriodicalId":399788,"journal":{"name":"7th GoGreen Summit 2021","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131043184","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}

Both of which can be proceeded for use as soil amendments. This research had two objectives: 1) to study the appropriate characteristics of the ratio between grease trap waste and water hyacinth for compost production and 2) to study the efficiency of compost from the growth rate of kale. The results of the analysis revealed that moisture, organic carbon, pH, conductivity, C/N ratio, nitrogen, phosphorus, and potassium are conformed to organic fertilizer standards of the Announcement by the Department of Agriculture: Criteria for organic fertilizers 2014, Thailand. Comparison of compost quality from macronutrients revealed that the ratio between grease trap waste and water hyacinth (2:1) was of the highest quality. Comparing the average growth rate of kale by plant height, a number of leaves, leaf width, leaf length, and fresh weight, found that the efficiency of compost containing grease trap waste and water hyacinth (2:1) affected the maximum growth rate of kale. In conclusion, the study found that the utilization of residues can reduce costs for waste management and increase resource renewal, which contributes to sustainability in future.","PeriodicalId":399788,"journal":{"name":"7th GoGreen Summit 2021","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116258629","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 pandemic has made urban residents to realize the importance of converting their grey to green roofs. The benefits of green roofs is manifold in nature as they not only add to aesthetically pleasing landscape but rather absorb rainwater, keeps the building warm, minimize air pollution, decrease stress of the people, improved human health and air quality. People now realize that green roof is the need of the hour because it promotes healthy living in cities in terms of nutritious food consumption, better air quality, and provide sense of mental peace and an agent of destressing busy life of the urban dwellers. Cities have been gradually been a better place since pandemic due to people’s choice to opt for gardening due to lockdown. So, in order to kill boredom, the urban residents opted gardening like vegetables, trees, and flowers on their grey roofs which in turn contributed to healthy cities. Thus, this paper will accentuate the significance of green roofs which in turn betters urban environment that have contributed for healthy living in cities.","PeriodicalId":399788,"journal":{"name":"7th GoGreen Summit 2021","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133883144","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}

Electric cars, as part of the alternative energy sector, have drawn worldwide interest due to their environmental friendliness. As a safer alternative to traditional combustion engines, electric cars and hybrid electric vehicles (EV/HEV) have gotten a lot of recognition around the world and are fast becoming a great alternative to internal combustion engine-powered vehicles. Electric vehicles are a great alternative to traditional vehicles. However, various characteristics of electric vehicles, such as performance, cost, battery life, and battery safety, restrict their growth. As a result, battery management is required to get optimal performance. A Battery Heat Management System is used to remove heat geenrated by the battery pack. The cost of a battery pack used in Electric Vehicle is high, which makes research in this area substantial in order to increase the lifespan of the battery pack. A battery heat management system that is powered by solar power from Photo-Voltaic with implementation of Maximum Power Point Tracking (MPPT) can be very substantial. The paper aims to do the same i.e. show the results of a simulation done to observe the effectiveness of the use of a Battery Thermal Management System, employing a Thermoelectric Cooler that is powered by a Photo-Voltaic with implementation of Maximum Power Point Tracking. The paper further proposes an arrangement of a copper casing outside the battery pack which consists of four Peltier devices, cooling the battery pack from four sides, and observe the effectiveness of the same via simulation.","PeriodicalId":399788,"journal":{"name":"7th GoGreen Summit 2021","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132036933","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}

A cross-sectional study was done. Three hundred eighty-four patients were selected by systematic random sampling and interviewed to answer the questionnaire at 2 diabetic centers in Alexandria. We found the respondents had fair knowledge (7.17±2.21 out of 10) and a positive attitude (3.682±0.87 out of 5) towards sharps disposal. However, the majority (95.1%) had poor disposal practices. Only (4.9%) of participants had acceptable disposal techniques through health care facilities. Good knowledge scores were related to high educational level, single marital status, living in an urban area, and being employed. Based on both crude and multivariable regression models, the study found that attitude was influenced by occupation status and that the parameters predicting disposal in healthcare settings were receiving advice from healthcare workers (HCW), knowledge score, and using insulin outside the house. In conclusion, most patients had inappropriate sharps disposal practices. Accordingly, the researchers expect a massive public health problem towards diabetic sharp waste discarding which implied the necessity to implement a proper community sharps disposal program in the future.","PeriodicalId":399788,"journal":{"name":"7th GoGreen Summit 2021","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127764452","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}

One of the significant changes is relating to the fast development of transportation infrastructures in these areas which gives rise to a quick change on the travel behaviours. Changing life style along with the city’s expansion, increasing population growth in urban areas and vehicular growth demand the design of new transportation system which is capable of meeting the free flow of traffic by assessing the carrying capacities of road network to accommodate increasing growth of vehicles on a time scale. Carrying capacity is a commonly used concept to represent the maximum flows that can pass through the roads without traffic congestion in transportation system. The authors of the present paper have designed a hypothetical ideal city having population of 10000 people with projected population up to year 2051 and corresponding estimation of increased vehicles through well-defined methods. The authors have also designed the road network to accommodate estimated vehicles to ensure free flow of traffic without any congestion by assessing the carrying capacity of such road network through compatible simulation models.","PeriodicalId":399788,"journal":{"name":"7th GoGreen Summit 2021","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130253205","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}
