Methods: Two sorption isotherm imitations namely, Langimuir and Frendlich sorption imitations had been utilized for descriping equilibria isotherm. Evaluation of the activating forces of sorption were carried out regarding sorption of indigo dye on both composites. Kinetics of the sorption model were studied and two kinetic imitations were utilized in an attempt for descriping the kinetics of the process with regard to the practically obtained information. Key findings: Regarding both composites, the psodo-second order kinetics imitation was suitable and is consistent with the practically obtained information. The activating force (Ea), difference in liberated energies (∆G), entalpy (∆H) and enthropy (∆S) of sorption methodology had been determined regarding the sorption of the indigo dye via both composites. The termodynamics of the sorption proved that the process regarding both composites had been both spontaneously and endothermically happening. Conclusion: The practically obtained information indicated that both of methylmethacrylate/sodium-Y-Zeolite composite and amidoximated polyacrylonitrile/sodium-Y-Zeolite composite might serve well as inexpensive, efficient and reproducible adsorbants to get rid of indigo dyes from wastewaters.","PeriodicalId":21655,"journal":{"name":"Scientific Journal for Damietta Faculty of Science","volume":"130 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90705519","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}

This paper proposes an image generation- based coverless steganography system which has the capability to transmit the secret message safely. The generated image is similar to the famous Quick Response (QR) code image; it is called semi-QR code in that paper. The proposed system consists of two processes, the first process, secret message hiding process, is used at the sender of the message and is responsible for generating the semi-QR code image from only the secret message bits using the hiding algorithm. While the second process, secret message extraction process, is used by the receiver of the message who can retrieve the secret message from the received semi-QR code image using the extraction algorithm. Finally, a coverless steganography system that implements the proposed algorithms has been built. To evaluate the effectiveness of these algorithms, experiments have been carried out using different evaluation measures, namely the Bit Error Rate (BER) and Success Rate (SR). The results confirmed that the proposed system is better than other traditional steganography systems achieving higher capacity and a higher level of robustness than them.","PeriodicalId":21655,"journal":{"name":"Scientific Journal for Damietta Faculty of Science","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90101404","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 background radiation levels, human exposure, dose rates, and potential radiation effects on the environment are all studied. The field geological investigation of the different rock units, with orientations to their mode of occurrence, common relationships, petrographic study and regional structure indicated that the investigated area is covered by Late Proterozoic igneous and metamorphic rocks. These basement rocks are included metavolcanics, metagabbros , granodiorites , younger gabbros, monzogranites, syenogranites, alkaline granites and alkaline syenites. The studied rock types have low uranium and thorium contents. The yearly effective dose, external absorbed dose rate in both indoor and outdoor environments, internal absorbed dose rate in both indoor and outdoor environments, and radium equivalent activity are all estimated. The investigation indicates that all the environmental impacts dose rates values in the studied rocks are lower than the public permissible values in these rocks and they are within the safety range for the public and workers. So, these rocks are safe for the building materials and can be used as ornamental stones.","PeriodicalId":21655,"journal":{"name":"Scientific Journal for Damietta Faculty of Science","volume":"47 2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81175570","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}
