A method for measuring chemical reaction rates in order to
distinguish between different reaction mechanisms is presented.
This method was used to study zero -, first- and second -order reactions
by analyzing the output response to a sinusoidal input of
reactant concentrations in an isothermal continuous stirred tank
reactor.
The...
The concept of terroir is commonly used as marketing tool to highlight unique characteristics of regional food products, however there is little scientific evidence of terroir pertaining to cheese. The purpose of this research was to investigate the potential impact of milk origin, pasteurization, and commingling on the sensorial, chemical,...
Milk collected from individual cows (n= 31) was centrifuged to equalize fat composition and was tested during chymosin-induced coagulation to compare the influences of somatic cell level, breed, parity, protein composition, and lactation stage on coagulation rate. Coagulation rate was determined using diffuse reflectance. Pearson correlation coefficients were calculated for...
Hauling is a critical part of the commercial milk supply chain, yet very few studies have aimed to understand its impact on raw milk quality. Consolidation of the American milk industry has led to the use of tanker trucks for up to 24 h between cleanings, which is the maximum...
This study examined the sex education practices of middle class parents with preschool children. Subjects were 128 parents of three- to five year -old children, including 37 mothers of daughters, 37 mothers of sons, 27 fathers of daughters, and 27 fathers of sons. These parents were administered a sex education...
This study examined children's memory for traditional and nontraditional
parental behaviors displayed in story content. Subjects
were 40 male and 40 female preschool children between the ages of 47
and 60 months. Children were read a story portraying a mother and a
father as the main characters. Each character performed...
The objective of this research was to investigate the influence of physicochemical
properties of lignocellulosic biomass on the rate and extent of cellulose conversion, i.e.
the "hydrolyzability" of the substrate.
The initial two parts of this thesis investigated the interactions between various
components of pretreated biomass. The relevance of cellulase...
Mycobacterium avium subsp. paratuberculosis (MAP) is a cause of
Johne's disease (JD) in cattle and other ruminants. MAP infection in the bovine
host is not well characterized. It is assumed that crossing the bovine intestinal
mucosa is important for MAP to establish infection. MAP's ability to infect
bovine epithelial cells...
A sensory method was developed to determine cheese texture by hand evaluation. Cheese sensory evaluation was conducted by panelists (n=8) on four commercial samples in duplicates. Standards, descriptors, methods of each attribute evaluation, sample size, and ballot were developed based on panelists' consensus. Fifteen total attributes, divided into five groups,...
