Optimizing The Use Of A Liquid Handling Robot To Conduct A High Throughput Forward Chemical Genetics Screen Of Arabidopsis Thaliana, B. Kirtley Amos, Victoria G. Pook, Seth Debolt

Horticulture Faculty Publications

Chemical genetics is increasingly being employed to decode traits in plants that may be recalcitrant to traditional genetics due to gene redundancy or lethality. However, the probability of a synthetic small molecule being bioactive is low; therefore, thousands of molecules must be tested in order to find those of interest. Liquid handling robotics systems are designed to handle large numbers of samples, increasing the speed with which a chemical library can be screened in addition to minimizing/standardizing error. To achieve a high-throughput forward chemical genetics screen of a library of 50,000 small molecules on Arabidopsis thaliana (Arabidopsis), protocols using a …

Service Drive 2020 - Fine Design, David Sirotinsky, Ling Marshall

Senior Design Project For Engineers

This report explores a cloud network solution for the automotive industry. The project scope was defined with a problem statement. Robust connectivity solutions offered by the OEM manufacturers provide data communication between the customer and the connected car, but lack data communication from the customer to the private franchise dealers. This antiquated business model creates variation in operation from one dealer to the other and creates a challenge to apply a standardized solution. One fundamental requirement is to provide a network solution that can seamlessly integrate into existing hardware, software and process infrastructure.

Beneficiation of Phosphates VIII

Sole active mining phosphate operation in European Union (EU) is in Finland Siilinjärvi with limited resources available for approximately next 20-30 years [1]. In this context it is important that Estonia holds the largest unused sedimentary phosphate rock reserve in EU. Estonian phosphate is a sedimentary rock composed of variegated sandstone that contains abundant remains (detritus) of (biogenic) phosphatic brachiopod shells [2]. Phosphate enriched beds occur stratigraphically at the transition between Cambrian and Ordovician and the phosphatic sandstones belong to Kallavere formation. The biogenic phosphate is dominated by francolite mineral phase. The P2O5 content of the sandstone beds is quite …
