The effect of various operational parameters on the COD removal efficiency was investigated based on response surface methodology (RSM). Optimal conditions were the current density of 20mA/cm2, FeSO4 concentration of, and time of  It achieved a COD elimination efficiency of 97.964 % at a specific energy consumption of 10.78 kWh/kg. The results indicated that time had the least effect on the efficiency with which chemical oxygen demand is eliminated, however, the share of current density had the greatest effect, followed by the FeSO4 concentration. The adequacy of the model equation was confirmed by its high R2 value (99.62%). The present study shows that the graphite–graphite EF system was an efficient tool for removing COD from hospital wastewaters.","PeriodicalId":227530,"journal":{"name":"Al-Qadisiyah Journal for Engineering Sciences","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124111070","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}

Thus, the primary issue that frequently arises in urban areas is on-street parking. In Al- Diwaniyah city's urban streets, on-street parking is a common occurrence. In order to analyze on-street parking characteristics, this study has concentrated on three congested sites: Al-Orzady Street, Al Saray Street, and Almusawreen Stree. Thus; field data were collected using in -out method. The characteristics and kind of parking were looked into. According to the activities at the three sites, it was mostly discovered that the peak time is in the afternoon between 3:10 PM and 4:40 PM. The results of the data analysis show that St3 has a high parking turnover of 1.348 and St1 has a low turnover of 0.67. It was also found through the questionnaire paper that the majority of the vehicles parked on the street are for the purpose of shopping. Finally, the results indicate that weekdays in the research area are a typical time for illegally parking.","PeriodicalId":227530,"journal":{"name":"Al-Qadisiyah Journal for Engineering Sciences","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133247444","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}

Dis/reassembly activities are delicate and need precise intervention due to the obligation of equipment refunctioning constraints.

The invisible architecture and in accordance with the environmental tendencies appeared as one of the contemporary trends to be that formation that achieves blend with the environmental surrounding and based on techniques that reduce its appearance in order to Emphasizing the importance of the external environment and trying to return to nature and increase green spaces in a manner that reduces pollution to a minimum so that this architecture is part of the site and not an added part to it, as well as its quest to increase operational efficiency and to reduce its negative impact on the environment in addition to improving the built environment that enhances health and well-being of the user. Many previous international studies highlighted various aspects of invisible architecture and the techniques and technologies for achieving them, noticing the limitation of Arabic and local studies that dealt with this topic. This research came to provide clear and comprehensive knowledge of the techniques of achieving invisible architecture in its environmental perspective with its multiple formations, which can be adopted effectively by The designer in general, and in a manner, that serves the reality of the Arab and local experience, in particular.
