Hybridization Of Dna By Sequential Immobilization Of Oligonucleotides At The Air-Water Interface, Murali Sastry, Vidya Ramakrishnan, Mrunalini Pattarkine, Anand Gole, K. N. Ganesh

Faculty Works

The hybridization of DNA by sequential electrostatic and hydrogen-bonding immobilization of single-stranded complementary oligonucleotides at the air-water interface with cationic Langmuir monolayers is demonstrated. The complexation of the single-stranded DNA molecules with octadecylamine (ODA) Langmuir monolayers was followed in time by monitoring the pressure-area isotherms. A large (and slow) expansion of the ODA monolayer was observed during each stage of complexation in the following sequence: primary single-stranded DNA followed by complementary single-stranded DNA followed by the intercalator, ethidium bromide. Langmuir-Blodgett (LB) films of the ODA-DNA complex were formed on different substrates and characterized using quartz-crystal microgravimetry (QCM), Fourier transform infrared …

Commercial Irrigation And Nutrition Practices For Strawberries In Western Australia, D. Phillips, D. Gatter, T. Calder, D. Pitman

Horticulture research reports

Irrigation practices employed by five commercial strawberry growers on sandy soils of the Swan Coastal Plain near Perth Western Australia were monitored for two consecutive seasons, 1995 and 1996 during the Spring production period.

Nutritional practices for the same grower group plus one Albany grower were monitored by plant, soil and sap analysis at 14 day intervals throughout the 1996 season.

Irrigation records showed that market quality strawberries could be produced at this time of year (August to December in Perth) on soils with very poor water retention properties with an average crop factor(E Pan) for the season of 0.7 …

Food For Thought On Cognitive Scripts And Genetically Engineered Food, Ibpp Editor

International Bulletin of Political Psychology

This article identifies some of the common thought sequences seemingly harbored by members of the sociopolitical opposition to the production and sale of genetically engineered food.

The Risks And Benefits Of Genetically Modified Crops: A Multidisciplinary Perspective, Garry D. Peterson, Saul Cunningham, Lisa Deutsch, Jon Erickson, Allyson Quinlan, Ernesto Ráez-Luna, Robert Tinch, Max Troell, Peter Woodbury, Scot Zens

Dartmouth Scholarship

Worldwide, the area planted in genetically modified (GM) crops has increased dramatically in recent years. Between 1996 and 1999, it rose from 1.6 X 10⁶ ha to more than 35 X 10⁶ ha (James 1998, May 1999). This rapid increase has provoked an explosion of concern, particularly in Europe, over the health and environmental impacts of these crops. Despite claims of safety and warnings against popular panic, public concern over GM crops has resulted in changes in their marketing, labeling, planting, and trade. These changes have fueled an increasingly heated debate among environmental advocates, critics of industrial agriculture, …

The Intellectual And Technical Property Components Of Pro-Vitamin A Rice (Goldenricetm): A Preliminary Freedom-To-Operate Review, R. David Kryder, Stanley P. Kowalski, Anatole F. Krattiger

Law Faculty Scholarship

Rice is a staple food for millions of people, predominantly in Asia, but lacks essential nutritional components such as Vitamin A. This is very important for over 180 million children and women of child bearing age who suffer from Vitamin A deficiency in Asia alone. For this reason, an improvement was made under an effort led by Profs. Ingo Potrykus and Peter Beyer by inserting several genes into rice to produce an improved product called GoldenRice. Because GoldenRice has the potential to be easily integrated into the farming systems of the world's poorer regions, the advent of GoldenRice promises to …

Prediction Of Rice Sensory Texture Attributes Using Spectral Stress Strain Analysis And Jack-Knife Model Optimization, Marura Lenjo, Jean-Francois Meullenet

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Sensory texture characteristics of cooked rice were predicted using an extrusion test and a novel multivariate analysis method. Eleven sensory texture characteristics were evaluated via a trained descriptive panel and predicted for force/deformation spectra with partial least squares regression. Only four sensory attributes—adhesion to lips (Rcal = 0.83), cohesion of bolus (Rcal = 0.78), cohesiveness (Rcal = 0.69), and hardness (Rcal = 0.72)—were successfully predicted from instrumental measurements.

Stock Market Reactions To Unfavorable Product Information: A Case Study Of Comments On Beef Safety Made On An Oprah Winfrey Show, Elpida Ormanidou, Michael Thomsen

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

This study examines the impact of unfavorable media coverage on the stock market prices of major food companies, an issue of increasing importance to the food industry. The study focuses on the 16 April 1996 Oprah Winfrey Show, a popular television program that raised questions about the safety of the U.S. beef supply. The show resulted in considerable controversy, and some cattle feeders blamed the show for a drop in cattle prices. The focus of this study is on the impact of the program at other stages of the food system. We examined the stock returns of two major beef …

Fissure Characterization Of Rice Kernels Using Video Microscopy, Jerry W. Fendley, Terry J. Siebenmorgen, Rustico C. Bautista

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Fissures are fractures of a rice kernel that can be created during the drying and tempering process. They cause tremendous postharvest losses in milling yield. Understanding why and how rice kernels fissure will lead to optimal drying and tempering operations. This information could also provide input to plant breeders for producing rice cultivars that are more resistant to fissuring. Rice kernels were dried using various air conditions in a controlled environment chamber. The kernels were viewed by video microscopy to observe the occurrence of fissures. A videocassette recorder recorded the images for a 24-hour period after the drying process. The …
