In this work, PVP-CMC-Gums hydrogel films were created from a variety of materials using casting and room-temperature drying processes; however, the impacts of adding bentonite clay, SEM, FTIR, XRD, TGA, swelling, melting, contact angle, and a set of experiments were performed to clarify and analyze a variety of physical, mechanical, thermal, and other characterizations. The main results revealed new peaks indicative of the presence of cross-linking, which is a major driver of loading and release properties, suggesting that these films can be used for drug delivery and a variety of other applications. PCXB film has the best properties in color, surface hydrophobicity, solubility, and swelling, while PCGB film has the best results in biodegradability and permeability, and the two films have strong thermal, and mechanical and release properties. Accordingly, the addition of bentonite clay to hydrogel films improves all their properties, making them suitable for diverse biomedical applications such as root canal fillings, tissue engineering, contact lenses, and dressings.","PeriodicalId":15747,"journal":{"name":"Journal of engineering sciences and information technology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88758555","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 water levels and velocity were recorded for periods, different stretches between the months of December of 2018 and March of 2019. The study dealt with the most important postural relationships that can be used to estimate the depth of future drift around the pillars. Description of the site of the studying region within Garmian region includes site measurements of the bridge span, height and pillars. Hydraulic properties of the basins was studied as well as the soil texture depending on clay, silt and sand portions was detected. The depth of the site erosion did not exceed the critical limit for some pillars because it did not reach the depth of the foundation, while reach the depth of the foundation of the others pillars. The flow around the abutments of the Dardween Bridge is of a critical type, so high drifts are -+expected. The results of the gradient examination of the size of the particles in the Garmian region, shows a high proportions of the Coarse and Fine aggregates \"gravel and sand\" in the soil which increasing the porosity and the permeability of the soil, thus increasing the possibility of erosion at the bases of the supports for bridges in this area due to high increasing water seepage. A proposal method was obtained by the current study to estimate the erosion around bridges pillars. Using deep piles foundations for the pillar bases instead and rock dam in front of the pile foundations to reduce the impact of the flow was recommended in this study.","PeriodicalId":15747,"journal":{"name":"Journal of engineering sciences and information technology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83484062","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 results from the increase of the internet-based-communications including the transfer of the digital data in text files, audio, video, and/or image formats. Which is why, multimedia and IT became one of the crucial parts of people’s daily lives. There are numerous threats that target Image integrity, confidentiality, and authentication, therefore, the information security is a very important concept. The Reversible Data Hiding (RDH) is a data hiding method. RDH-Encrypted Image (RDH-EI) procedure which is working through embedding additional data to an image had emerged. Lately, the RDH-EI with the wide range is used, which is why, it has attracted the interest and focus of the employers as well as the academics. Thus, a survey that discusses previous researches will be carried out for the purpose of identifying the most significant (RDH-EI) approaches throughout the past five years. Several methods of RDH-EI with the different embedding rate, when its value is low (< 0.1 bpp), it is impossible to reconstruct the image without fault. Otherwise in the case where the embedding rate is high (>0.1 bpp), it is possible to obtain an image that is quite similar to the original image but it still needed for preprocessing step.","PeriodicalId":15747,"journal":{"name":"Journal of engineering sciences and information technology","volume":"78 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81233093","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}
