INSIGHTS INTO THE NATURAL DEGRADATION RATE OF PLASTICS IN THE SEAWATER ENVIRONMENT AND THEIR DEGRADATION BY-PRODUCTS (PHTHALATES AND BISPHENOL A)
(2023 , Master Thesis)Most plastics end up in the oceans. Their chemical additives that leach out into the ocean can be detrimental to humans and animals. This study investigates the degradation-fragmentation of different plastic types for 140 ... -
INSTITUTIONALISM AND THE DYNAMICS OF RESOURCE-BASED DEVELOPMENT IN THE ARAB GULF STATES: AN EMPIRICAL ANALYSIS
(2025 , Dissertation)This study aimed to address a theoretical and practical issue in Gulf and Middle East studies, namely the dominance of the rentier paradigm in understanding the relationship between natural resource abundance and socio-economic ... -
An Integrated Approach to Benthic Habitat Classification of the North Eastern Qatar Marine Zone Using Remote Sensing, Geographic Information System, and in Situ Measurements
(2014 , Master Thesis)A key aspect in the conservation management of the coastal marine zone is mapping the benthic habitat, which is the focus of the work presented in this project. Multispectral Worldview-2 (WV2) satellite data acquired in ... -
INVESTIGATING THE MOLECULAR MECHANISMS UNDERLYING THE ANTI-CANCER ACTIVITIES OF DIOSMETIN IN COLORECTAL CANCER CELLS: AN IN VITRO STUDY
(06-2 , Master Thesis)Diosmetin, a bioflavonoid isolated from citrus fruits, has been reported to have cytotoxic effects against various types of cancer. Although Diosmetin is found to have cytotoxic effects in Colorectal Cancer (CRC) cells, ... -
Investigation and Biological Control of Toxigenic Fungi and Mycotoxins in Dairy Cattle Feed
(2020 , Master Thesis)Mycotoxins are secondary metabolites synthesized by mycotoxigenic fungi, contaminating human and animal food and feed. Aflatoxin B1 (AFB1) and ochratoxins (OTA) are frequently detected in animal feed products causing ... -
