EFFECTIVE COLLEGE TEACHING AND STUDENTS’ RATINGS OF TEACHERS: WHAT STUDENTS THINK, WHAT FACULTY BELIEVE, AND HAT ACTUAL RATINGS SHOW IMPLICATIONS FOR POLICY AND PRACTICE IN TEACHING QUALITY ASSURANCE AND CONTROL IN HIGHER EDUCATION IN OMAN
… examines the extent to which teachers’ (N=248) and students’ (N=968) perceptions of effective teaching and students’ evaluations of teachers in six colleges of technology in Oman match or mismatch. It also investigates Omani students’ (N=922) ability to identify the teaching dimensions …

Comprehensive modeling of process-molten pool condition-property correlations for wire-feed laser additive manufacturing
… high level of automation, high deposition rates, and good quality of printed parts. The complexity of modeling the directed energy deposition (DED) process, high characterization and printing cost, and the destructive testing of the final build part for quality testing motivates the need for …

Application of diffusive gradient in thin-film passive samplers to assess mercury availability and mobility in a fresh water river system
… require removal of sediment, transportation, and processing. Passive sampling is an alternative technique that measures sediment porewater concentrations in-situ and without significant sample disturbance. One passive sampling technique for mercury in sediment porewater is Diffusive Gradient …

The development of PCR internal controls (PICs) for forensic DNA analysis
… interpretation of DNA profiles depends on the quality of the DNA samples, the amplification efficiency and the success of post-PCR processing. Chemicals associated with forensic samples can affect the amplification process while random errors occurring during pipetting and electrokinetic …

Recognising cryptic alteration surrounding the Mount Isa Copper Deposits: Implications for controls on fluid flow, and mineral exploration
… mineralisation at Mount Isa, Northwest Queensland, Australia. New insights from hydrothermal alteration were used to constrain aspects of hydrothermal fluid flow and fluid-rock interactions that occurred as part of the mineralising system responsible for forming this world-class orebody. This …

Development and Evaluation of Infilling Methods for Missing Hydrologic and Chemical Watershed Monitoring Data
… success rates due to a variety of field and laboratory factors. A major source of error in many stream-gaging records is lost or missing data caused by malfunctioning stream-side equipment. Studies estimate that between 5 and 20 percent of stream-gaging data may be marked as missing for …
