(North Dakota State University, 2011)
Throughout the history of Western Music, composers have written works on rural and agricultural subjects. The first half of this dissertation examines a number of important works from the Baroque era through the present ...
Studies on the Biology of Soybean Cyst Nematode
(North Dakota State University, 2011)
Soybean cyst nematode (SCN), Heterodera glycines, is a threat to soybean production in North Dakota. Studies on the biology of SCN were conducted to improve my understanding and management of this plant parasitic nematode. ...
Phenotypic and Genotypic Effects of FlhC Mediated Gene Regulation in Escherichia Coli O157:H7
(North Dakota State University, 2011)
Escherichia coli (E.coli) 0157:H7, a pathogen belonging to the enterohemorrhagic group of E.coli, has long been a concern to human health. The pathogen causes a myriad of symptoms in humans, ranging from diarrhea and malaise ...
Gene Regulation in Biofilms
(North Dakota State University, 2011)
Sessile bacterial communities which form on the solid surface or solid-liquid interface
are known as biofilms. Both single species and multispecies biofilms are characterized
by an extracellular matrix of polymeric ...
Prevalence of Pathogenicity Groups of the Blackleg Species Complex on Canola in North Dakota
(North Dakota State University, 2011)
North Dakota is the leading producer of canola (Brassica napus) in the United States. Blackleg, caused by two species of Leptosphaeria, L. maculans (Desm.) Ces & De Not and L. biglobosa, is an economically important disease ...

(North Dakota State University, 2011)
Blackleg is a disease of canola and rapeseed cultivars that is caused by the fungus Leptosphaeria maculans (Desm.) Ces. & de Not., and it is by far the most destructive pathogen of canola in North America. In recent years, ...
Factors Affecting Grapevine Establishment in Northern Production Regions
(North Dakota State University, 2011)
Two experiments were conducted to detect differences in growth and cold hardiness during establishment of northern grown wine grapevines. One experiment tested the use of four grow tube treatments and two pruning levels ...
Comparison of Proposed K Sample Tests with Dietz's Test for Nondecreasing Ordered Alternatives for Bivariate Normal Data
(North Dakota State University, 2011)
There are many situations in which researchers want to consider a set of response variables simultaneously rather than just one response variable. For instance, a possible example is when a researcher wishes to determine ...
Mass Spectrum Analysis of a Substance Sample Placed into Liquid Solution
(North Dakota State University, 2011)
Mass spectrometry is an analytical technique commonly used for determining elemental composition in a substance sample. For this purpose, the sample is placed into some liquid solution called liquid matrix. Unfortunately, ...
A Proposed Nonparametric Test for Simple Tree Alternative in a BIBD Design
(North Dakota State University, 2011)
A nonparametric test is proposed to test for the simple tree alternative in a Balanced Incomplete Block Design (BIBD). The details of the test statistic when the null hypothesis is true are given. The paper also introduces ...
