Evaluating Different Densities Of Lettuce (Lactuca Sativa L) With Varying Levels Of Feeding Regimes On Tilapia Fish (Oreochromis Niloticus L) In Aquaponics System, Ahmed Salem Mohammed Suhail Alkaabi

Theses

Aquaponics uses waste generated by fish as plant nutrients within a re-circulating system that returns clean water back to the fish. The purpose of this study was to cultivate the high quality of lettuce (Lactuca sativa L.) and Tilapia (Oreochromis niloticus L.) production in an integrated aquaponic system with recirculating aquaculture system in the UAE climatic condition on three different densities and feeding regimes. An experiment was conducted under greenhouse conditions in the United Arab Emirates in 2016 (from April to August). The evaluation of the production was based on three parameters viz., head of the …

Study Of Rheological, Chemical, And Microbiological Properties Of Chami, A Traditional Emirati Soft Chees, Aysha Othman Abdullah Al Katheeri

Theses

In this work, ten Emirati Chami cheese samples were collected and analyzed to determine their chemical composition, texture, rheology, and microbiological properties. Chami cheeses showed large variations in moisture (60.9–84.1%), protein (7.5–14.6%), fat (0.5–7.8%), and ash (3.4–8.0%) contents as well as in pH (3.6–4.4), and water activity (0.977–0.999%). The variation in fat content of samples suggested that extra fat was added; this added fat was either butter or vegetable oil as indicated by the fatty acid composition. The different samples showed peaks of variable size for fat melting. The sodium content in the 10 cheese samples varied from 223–2410 mg/kg, …

Role Of The Snf2 Homolog, Irc20, In Yeast Genome Maintenance, Deena Mohamed Galal Eldin Ahmed

Theses

In eukaryotes, DNA is wrapped around histone proteins forming a highly compact structure, the chromatin. All DNA-based processes must occur within the complex organization of the chromatin, and this requires modulation of its structure when needed. This is accomplished by covalent histone modifications that alter histone-DNA contacts, as well as through the actions of ATP-dependent chromatin remodelers. These multi-subunit complexes play major roles in transcription regulation, replication and repairing DNA damage. This thesis aims to characterize a poorly studied member of the SWI/SNF family of ATPases/helicases, Irc20, from Saccharomyces cerevisiae. Previously, Irc20 has been shown to be involved in …

Determination Of The Ideal Plant Density Of Tomato Solanum Lycopersicum Under An Aquaponic Production System With Tilapia Oreochromis Aureus Under Uae Conditions, Mohamed Ahmed Al Dhanhani

Theses

Aquaponics is an agricultural system that saves water and fertilization and offers a way of growing plants without soil pest infestation or pesticide residues. This system ensures the production of hazardous chemical free food for humans. This system also ensures sustainability by creating a natural relationship between fish and plants and makes gardening more productive and economical.

Aquaponics system is a dynamic ecosystem that can be integrated to achieve food security through the production of fish and vegetables without the intervention of fertilizers.

The focus of this study is optimizing planting density of tomato in an aquaponics system; with assess …
