The corn cob-derived biochar (CDB), generally, had a stronger restorative effect on soil ammonium nitrogen, nitrate and total organic nitrogen concentrations than the bone-derived biochar (BDB). Both biochar types had a more robust impact on restoration of Nitrosomonas, Nitrobacter and Azotobacter abundance (with the re-establishment of pre-pollution levels) than on Rhizobium and Pseudomonas aeruginosa. Biochar amendment restored the activity of AMO enzyme in the soil by week 15. The CDB (72.4% – 73.7%) showed more effective total petroleum hydrocarbon (TPH) elimination capacity than the BDB (51.1% – 57.7%). Biochar amendments exhibited great potential for restoration of nitrogen cycling while facilitating remediation of petroleum-polluted soils.","PeriodicalId":15885,"journal":{"name":"Journal of Fundamental and Applied Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41932540","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 UPDT switch is a software-based timer with an interface that can be connected to a variety of devices to act as a switch for their operations. It is designed to perform a cyclic operation up to 100 times with a maximum switching time of 100 hours.

The result of the analysis shows that the stress concentration is localized at the volute nozzle for all the three types of forms. This founding is an interesting element as regards to the possibilities of adaptation of a pump to a particular operation. Also it is found that the tangential volute is the least stressed compared to the other two forms. The displacements are more pronounced in the case of a radial volute. These data can be exploited in order to predict the possibility of accidental rupture of this element. From another point of view this can have an indirect influence on the appearance of vibration, noise and fluctuations of pressures and speeds due to the interaction between the fixed part (volute) and the mobile part (impeller).","PeriodicalId":15885,"journal":{"name":"Journal of Fundamental and Applied Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47386691","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}
