The effects of dietary algal and lipid supplements on the gonadal and larval development of Crassostrea gigas kumamoto (Thunberg)

Creator:: Robinson, Anja M.
Abstract:: Under laboratory conditions, elevated temperatures accelerated production of gametes. However, when conditioning for spawning at elevated temperatures was initiated early in the season (January-March), larval survival and number of spat collected were significantly lower than when conditioning was initiated in may or June. At elevated temperatures, broodstock oysters were fed...

Carrying Things Home from School : Can a Child-Based School Intervention Affect Parenting Strategies and Home Climate?

Creator:: Godlewski, Bethany J.
Abstract:: School interventions have typically focused on academic and psychological outcomes for children, but can children carry positive effects home from school to influence their parents and home environments? Developmental research typically focuses on how parents influence development in their children, but this study flips this lens to ask whether children...

Gender Matters : The Perspectives and Experiences of Living Unit Staff in Juvenile Correctional Facilities

Creator:: Galardi, Tasha Randall
Abstract:: Front line staff members in youth correctional facilities are generally the primary adults in the lives of incarcerated young people. In many ways, they serve as surrogate parents who may promote positive development while holding delinquent youth accountable for their actions. They accomplish these often conflicting goals through the provision...

Disengaged and untrusting? Young adults' feelings of social integration and trust during the Great Recession

Creator:: Day, Jack K.
Abstract:: Navigating the transition to adulthood is fraught with challenges, especially for those coming of age during an economic crisis. Individuals often rely on support from existing social networks, and establish social capital through deepening and expanding social ties, as they establish footholds in roles marking adulthood. Yet investing in social...

Formation of N-nitrosamines from the nitrosation of spermidine and spermine

Creator:: Hildrum, K. I. (Kjell Ivar), 1940-
Abstract:: The reactions between sodium nitrite and the polyamines spermidine and spermine were investigated. When reacted at 80°C for 1 hr at pH 3.5 with a 1:3 molar ratio of amine groups to sodium nitrite, five volatile nitrosamines were identified as products in the nitrosation of spermidine. 3HC1, and two volatile...

Determination of selected secondary and tertiary amine alkaloids in barley malt

Creator:: Poocharoen, Boonthong
Abstract:: The malt alkaloids N-methyltyramine, N,N-dimethyltyramine (hordenine), N-methyl-3-aminomethylindole and N,N-dimethyl-3-aminomethylindole (gramine) are known precursors for N-nitrosamines. Analytical procedures were developed and applied to extract and quantify these alkaloids from malt, green malt, malt roots, and raw barley. A ground malt sample under nitrogen atmosphere was extracted with 5 percent concentrated ammonium...

Identification and quantitation of 3-hydroxy-N-nitrosopyrrolidine in fried bacon and fried-out fat

Creator:: Lee, Jae-sung
Abstract:: The formation of 3-hydroxy-N-nitrosopyrrolidine from decarboxylation of 4-hydroxy-N-nitrosoproline was demonstrated in model heating system designed to simulate the conditions of frying bacon. The identification of the nitrosamine was achieved by comparison of its TLC R [subscript f] value, gas chromatographic retention time, and mass spectral fragmentation pattern with those of...

Formation of N-nitrosodimethylamine and nonvolatile N-nitrosamines from barley malt alkaloids

Creator:: Mangino, Mario M.
Abstract:: Amines formed by biosynthesis in germinated barley have been suggested as precursors for N-nitrosodimethylamine (NDMA) in barley malt dried by direct-fired kilning. This hypothesis was verified by germinating raw barley and exposing the resulting malt roots and clean malt to nitrous acid. Quantitation of the NDMA formed indicated that malt...

Family planning and sexual risk-taking among Mexican immigrant men : how does fatherhood matter?

Creator:: Cancel-Tirado, Doris I.
Abstract:: Men are frequently left out of the picture in the study of family planning and sexual risk behavior. This approach means few programs and policies address men's family planning and sexual health issues. There is also a lack of understanding of the role fatherhood plays in men's development and in...
