Thresholds of uncertainty : radiation and responsibility in the fallout controversy

Creator:: Jolly, J. Christopher
Abstract:: The public controversy over possible health hazards from radioactive fallout from atomic bomb testing began in 1954, shortly after a thermonuclear test by the United States spread fallout world wide. In the dissertation, I address two of the fundamental questions of the fallout controversy: Was there a threshold of radiation...

Interrelationships among changes in flavor and aroma, and composition of stored strawberry juice concentrate

Creator:: Lundahl, David S.
Abstract:: Sensory evaluation and instrumental methods were applied to the evaluation of strawberry juice concentrate (68°Brix) stored at 20°C which had been produced both commercially (C-SJC) and in a pilot plant (SJC). Sensory evaluation included taste and aroma ratings by intensity scaling and time-intensity of taste, and visual colorimetry by matching...

Purification of strawberry polyphenol oxidase and its role in anthocyanin degradation

Creator:: Wesche-Ebeling, Pedro Alfredo E.
Abstract:: Polyphenol oxidase (PPO) from strawberries was purified, partially characterized, and used to study its role in the degradation of anthocyanin pigments. The extraction method included the use of a buffered solution containing the phenolic binders Polyclar AT and Amberlite XAD-4. Addition of Triton X-100 resulted in an increase of the...

Perceptual characteristics of selected acidulants by different sensory and multivariate methods

Creator:: Rubico, Sonia Mendoza
Abstract:: The taste qualities of acidulants have not been studied in detail despite the fact that they are widely used by the food industry. Studies on characterizing the sensory properties of organic and inorganic acids are very limited. Reported studies are commonly on threshold, equi-sour and the time intensity values of...

Utilization of wastes from Pacific whiting surimi manufacturing : proteinases and protein hydrolysate

Creator:: Benjakul, Soottawat
Abstract:: Both liquid and solid wastes from Pacific whiting surimi manufacturing were characterized and value-added products were recovered. A proteinase in surimi wash water (SWW) was determined to be cathepsin L with Mr 54,200 on SDS-substrate gel. Heat treatment and acidification shifted the activity zone to M [subscript r] 39,500. No...

Influence of vine vigor and shading in Pinot noir (Vitis vinifera L.) on the concentration and composition of phenolic compounds in grapes and wine

Creator:: Cortell, Jessica M.
Abstract:: In 2003 and 2004 vigor zones were delineated in two commercial vineyard sites based on vine growth variation to assess fruit and wine phenolic chemistry. In 2004, the effects of shading on the accumulation of phenolic compounds were also investigated. Model extractions were done from the shading experiment and the...

Deterministic and stochastic behaviors of a piecewise-linear system

Creator:: Mha, Ho-Seong
Abstract:: The (nonlinear) response behavior of a piecewise-linear system is investigated under both deterministic and stochastic excitations in this study. A semi-analytical procedure is developed to predict the system behavior by evaluating the joint probability density functions of the Fokker-Planck equations of the stochastic piecewise-linear system under random excitations via a...

“I Could Make Impossible Things Happen”: Latina Entrepreneurs Nurturing Intuitive, Spiritual, and Relational Knowledge to Grow a Business

Creator:: Fonseca, Ana Lucia
Abstract:: Entrepreneurship is regarded as a viable way for women to enter the economy and improve their quality of life (Morris et al., 2018). However, little attention has been paid to understanding how women, and specifically women of color, utilize their ways of knowing to learn entrepreneurship. Grounded in Chicana/Latina feminism...

The effects of N-1-Naphthylphthalamic acid on growth of yellow nutsedge and its control with N-Phosphonomethyl glycine

Creator:: Paller, Enrique C.
Abstract:: Greenhouse and growth chamber experiments were conducted with the following objectives: (a) to study the effects of N-1-naphthylphthalamic acid (naptalam) on shoot and tuber production, rhizome transformation, and growth of yellow nutsedge (Cyperus esculentus L.) plants; (b) to study the effects of N-phosphonomethyl glycine (glyphosate) on nutsedge plants at different...
