There has been an increasing interest in recent years in developing and using computer-based tests in educational assessment. To replace pap er-based tests with computer-based ones, the standa rds for developing computerized-assessme nt (International Test Commission., 2004 ) requires equivalent test scores to be established for the new computer-based test and the conventional paper-based test....

Advances in modern day technology are rapidly increasing the ability of engineers to automate ever more complicated tasks. Often these automated aids are paired with human operators who can supervise their work to ensure that it is free of errors and to even take control of the system if it malfunctions (e.g., pilots supervising an autopilot feature). The goal of this collaboration, between hum...

INTRODUCTION Mobile work is not equivalent with telework, but the two share some characteristics. Our definition of mobile CSCW (Computer Supported Co-operative Work) includes (1) Individual workers move among several locations, as required by the objects of activity being to at least some part located outside of the computer; (2) People working together may be physically separated. Let us at s...

We examine spatial competition along a waterway when shippers are distributed over space. Competition is between barge and rail companies and among barge companies. Equilibrium prices are derived for two variations: oligopolistic rivalry between barge and rail operators, and oligopolistic rivalry among barge operators with terminals located at different points on the waterway. In the first vari...

Supervising Supervisors and Ph.D. Candidates on the development of supervision as a form of instruction and a pedagogic instrument in postgraduate education

Expression levels of the NAC gene family were studied in rice infected with Rice dwarf virus (RDV), Rice black-streaked dwarf virus (RBSDV), Rice grassy stunt virus (RGSV), Rice ragged stunt virus (RRSV), and Rice transitory yellowing virus (RTYV). Microarray analysis showed that 75 (68%) OsNAC genes were differentially regulated during infection with RDV, RBSDV, RGSV, and RRSV compared with th...

Rice Bran Protein Fractions (RBPFs) albumin, globulin, glutelin and prolamin were extracted from untreated and parboiled rice bran and their comparative studies were made for the yield, protein content, bulk densities, water absorption capacities, Nitrogen Solubility Index (NSI), emulsion property and least gelation concentration. The maximum yield of the protein fractions were obtained in parb...

The influence of oil rate and quality of rice bran oil by enzymatic extraction ultrasonic assisted were studied through designed experiment. The optimum enzymatic hydrolysis conditions were determined by the way of the orthogonal test. The results showed: after lipase enzyme in the rice bran (40 mesh sieve) was killed by the hot steam, the solution compounding material liquid ratio was 1:5 (W/V...

Rice bran is a simple item that delivers fantastic health benefits in our daily diet. This study delivers the importance of utilising all parts of the whole grain, including the bran. The objective was to develop the recipes incorporated with rice bran and evaluate their organoleptic properties and estimate their glycemic index. Ten standard Indian subcontinent recipes namely, chapati, mixed ve...

To establish the effectiveness of a new phytosterol-containing spread derived from rice bran oil (RBO), a randomised, double-blind, cross-over human clinical trial was conducted over 12 weeks. A total of eighty mildly hypercholesterolaemic (total blood cholesterol level ≥ 5 and ≤ 7·5 mmol/l with a serum TAG level of ≤ 4·5 mmol/l) individuals were randomised into two groups (n 40). Group 1 consu...
