(5+6)/7, (3+4)/2, (11+12)/8 and ii. 3/2, (3+4)/2, (6+7)/5] were demonstrated to the oil spills that occurred off Mauritius, Indian Ocean, on August 06, 2020, and Norilsk region, Russia on May 29, 2020, and the results were published in the peer-reviewed research journals. Recently (August 19, 2021), our methodology was recognized by the Sentinel-Hub (a repository of custom scripts) https://custom-scripts.sentinel-hub.com/sentinel-2/oil-spill-index/ for OSI calculation. We validated the remote sensing results with the drone images taken during the incident. Our OSI index is the first to be applied to Sentinel-2 optical data to map oil spills. We proved the potential of indices and the capability of Sentinel sensors to detect, map, monitor, and assess the oil spill, which can be used for emergency preparedness of oil spills.","PeriodicalId":9295,"journal":{"name":"Building Resilience at Universities: Role of Innovation and Entrepreneurship","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88476926","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}

Unfortunately, malignant tumors has the capability to metastasis, which involves both migration and invasion of cancer cells which are the most threatening aspects of cancer (McSherry et al., 2007). Consequently, researchers have concentrated on Complementary and Alternative medicine (CAM) modalities, as conventional medicine has been facing various challenges such as; poor understanding of the mechanisms with BC proliferation and invasion within various groups of patients, drug resistance, and the failure of current therapies to completely cure the disease. A significant CAM method have been raised which is the treatment with herbs and extracts derived from seeds, leaves, fruits and roots of plants; each of these invariably represents a combination of several bioactive compounds. Our biofuel has provided us with a crude extract of a microalgae coded as T1 that consist of carotenoids, chlorophyll a, and chlorophyll b. Carotenoids is a bioactive molecule that inhibits the proliferation, migration, invasion and induce apoptosis to tumor cells.","PeriodicalId":9295,"journal":{"name":"Building Resilience at Universities: Role of Innovation and Entrepreneurship","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80854161","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}

Therefore, it is of utmost relevance to developing strategies that can repair the damaged part of the coatings to protect the base metal and restrict the initiation of corrosion. Towards this direction, the concept of double-layered polymeric coatings (DLPCs) for corrosion protection is introduced as a novel strategy to bring different healing functionalities into coating matrices. The developed DLPCs are composed of a top layer containing 5wt. % of melamine urea-formaldehyde microcapsules (MUFMC) encapsulating boiled linseed oil (self-healing agent), and bottom layer having 3wt. % benzotriazole (corrosion inhibitor) loaded into halloysite nanotubes (HNTs). The DLPCs were developed on mild steel substrate employing a doctor blade technique. The electrochemical analyses indicates that the DLPCs demonstrate improved corrosion resistant properties. This improved performance can be ascribed to the efficient triggering of the individual carriers in the quarantined matrix, resulting in enhanced corrosion efficiency of the DLPCs. The promising characteristics of DLPCs make them suitable for many potential industrial applications.","PeriodicalId":9295,"journal":{"name":"Building Resilience at Universities: Role of Innovation and Entrepreneurship","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80962243","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}

T2DM is associated with a high risk of cardiovascular (CV) morbidity and mortality, and progression of renal disease. Sodium glucose co-transporter 2 inhibitors (SGLT2is) are the most recently approved class of glucose lowering medications (GLMs). To date, there is a limited knowledge about the adoption of SGLT2is by clinicians compared to other oral GLMs in Qatar and Middle East and North Africa (MENA) region. Accordingly, this proposed study aims to explore the trends in SGLT2is use compared to other oral GLMs in Qatar from 2016 to 2020. Methods: This is a descriptive, retrospective cross-sectional study where information on all oral GLMs prescriptions dispensed as in- or out-patient from 2016 to 2020 in all Hamad Medical Corporation (HMC) hospitals were collected. Outcomes included the number and relative frequency of quarterly prescriptions of different oral GLMs classes [metformin, sulfonylureas (SUs), dipeptidyl peptidase 4 inhibitors (DPP-4is), thiazolidinediones (TZDs), meglitinides (MEGs), α-glucosidase inhibitors (AGIs), and SGLT2is] from 2016 to 2020. Results: Overall, the prescription rate of GLMs increased during the last five years. SGLT2is use increased over the years after being introduced to the formulary in 2017, replacing SUs which exhibited significant decline between 2017 and 2020. There was a slight reduction in metformin use, and a slight increase in DPP-4is use. TZDs, MEGs, and AGIs prescriptions remained stable. Among SGLT2is, empagliflozin showed considerable increase on the expense of dapagliflozin which decreased significantly by the end of 2018. Conclusion: SGLT2is have been gradually replacing SUs in Qatar and the trend of their use is similar to that reported in other countries. The trend among SGLT2is suggests greater preference for empagliflozin over dapagliflozin.","PeriodicalId":9295,"journal":{"name":"Building Resilience at Universities: Role of Innovation and Entrepreneurship","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81737580","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}
