Uncovering limitations and opportunities in nitrogen fixation in soybean using genetic mapping and transgenic approaches
(University of Missouri--Columbia, 2023)
is limited and is important in modern agriculture as it benefits farmers and the environment by eliminating the requirement of synthetic N fertilizers to achieve high yields. Development of legume nodules and active SNF are complex processes which involve...
Ion-selective electrodes for simultaneous real-time analysis for soil macronutrients
(University of Missouri--Columbia, 2006)
, and of cobalt rod-based phosphate ISEs were satisfactory for measuring N, P, and K ions over typical ranges of soil concentrations. The nitrate ISEs, when used in conjunction with the Kelowna extractant (0.25M CH₃COOH + 0.015M NH₄F), provided soil NO₃-N values...
Minimum milk requirement for calf raising
(University of Missouri--Columbia, 1919)
The dairyman is keenly interested in knowing how he can raise his calves in an economical and successful manner. This thesis reports the results of several experiments in early weaning and minimum use of milk for calf ...
An economic analysis of the agricultural development potential for Southern Honduras
(University of Missouri--Columbia, 1975)
for various resources r which would provide guidance for making investment decisions; and (3) to derive policy recommendations for the purpose of agricultural development in Southern Honduras. A survey of 449 randomly selected sample farms, including 686...
Value addition to acid whey from Greek yogurt processing with millets (kodo and proso) for development of nutritious food products
(University of Missouri--Columbia, 2022)
properties and if there was any enhancement or degradation. The matrix was also analyzed for its encapsulation potential for folic acid (Vitamin B9) In terms of chemical properties, increase in antioxidant properties and decrease in antinutritional factors...
Estimates of correlation between estrus behavior and estradiol concentrations during estrus
(University of Missouri--Columbia, 2020)
-class correlation (r) for rump touches and steps was approximately 0.45. Experiment 3 focused on the association between circulating concentrations of estradiol and overt phenotypes for estrus [greater activity and (or) rump touches (mounts, chinrests, etc...
Hierarchical nonlinear, multivariate, and spatially-dependent time-frequency functional methods
(University of Missouri--Columbia, 2013)
through carefully chosen basis expansions (empirical orthogonal functions) and feature-extraction stochastic search variable selection (SSVS). Properties of the methodology are examined through an extensive simulation study. Finally, we illustrate...
Multi-scale factors influencing detection, site occupancy and resource use by foraging bats in the Ozark Highlands of Missouri
(University of Missouri--Columbia, 2007)
Conservation of bat populations requires understanding the associations between bats and their use of resources. We used maximum likelihood to estimate probability of site occupancy using acoustic data for ten species of ...
Average treatment effect evaluation with time-to-event data in randomized clinical trials and observational studies
(University of Missouri--Columbia, 2023)
contained in the initial event. Corresponding to this, Chapter 3 presents a sieve maximum likelihood approach that makes use of the ancillary information contained in the initial event. The logistic model and Cox proportional hazards model are employed...
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
(University of Missouri--Columbia, 2017)
step in assessing populations. We surveyed 14 sites in the Meramec River Basin in East-central Missouri to determine the effectiveness of visual sampling methods and to determine the effects of habitat variability on the effectiveness of these methods...
Middle and late woodland period cultural transmission, residential mobility, and aggregation in the deep South
(University of Missouri--Columbia, 2009)
This research attempts to reconstruct the extent of prehistoric human interaction within the lower Chattahoochee-Apalachicola River valley and neighboring Gulf Coast for the period spanning 200 B.C. to A.D. 1000. Using evolutionary models...
Animals in Rome
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Humans have coexisted intimately with animals for thousands of years, yet our relationship with them is still fraught with uncertainty. Animal behavior is so similar to our own...
"Rape is a part of life where I live" the normalization of girl-child sexual abuse in Jamaica
(University of Missouri--Columbia, 2022)
This research focused on understanding the role of institutions, social and cultural factors, and women's socio-economic status in (re)producing and perpetuating the sexual abuse of girls in Jamaica. Using an interpretive ...
