Investigating The Prevalence Of An Insecticide Resistance Gene In Culex Mosquito Populations Of Central Illinois, Kylee R. Noel

Masters Theses

The globalization of society has led to the spread of the vectors, mosquitoes, and diseases. Each year millions of people are killed by diseases vectored by mosquitoes. For example, West Nile Virus alone killed over 2,000 people in North America in 2017; 8 of those deaths being in Illinois. Two prominent vectors of West Nile Virus are Culex pipiens and Culex restuans; which are difficult to differentiate based upon morphological features. In this study, mosquitoes collected from two Illinois counties, Coles County and Champaign County, were first identified based upon morphology and this identification was then compared to probe-based …

Pokemon Go And Mental Health, Nathaniel Ed

Much research has been conducted on the effects of gaming on mental health, but to date no research has been done on the possible correlations of the game Pokémon GO and mental health. The present study was conducted to determine whether Pokémon GO players scored significantly lower than a control group of traditional garners on scales of depression, anxiety, and pathological gaming, and if they reported …

Government Expenditure And Unemployment: Empirical Investigation Of Sub-Saharan African (Ssa) Countries, Grace Ayiwah Fosu

Masters Theses

Over the years, there have been increasing trends in government expenditures in most countries in Sub-Sahara Africa, but some of the social-economic indicators such as health, unemployment, education, inflation, and the others paint a blurry image of the effect of the rising public spending. It is worrisome to see that pictures painted by the economic indicators show that budgets made by governments in Sub-Sahara Africa look good on paper than their actual effect in the economy (Andrews, 2010; Peterson, 2010). As a result of this, the question that keeps emerging is that “does government spending actually impact economic indicators in …

Asphaltene Stability In Crude Oil During Carbon Dioxide Injection And Its Impact On Oil Recovery: A Review, Data Analysis, And Experimental Study, Sherif M. Fakher

Masters Theses

"Crude oils are usually associated with many compounds, some of which are favorable and others, which are not. One of the most unfavorable components of crude oil that pose severe operational problems and decreases oil production significantly are asphaltenes. These compounds are solids that are homogenized in the crude oil at room temperature but tend to separate from solution when agitated. They can deposit in the reservoir pores, wellbore, and transportation pipelines thus causing severe operational problems and oil recovery reduction.

Even though researchers have been studying asphaltenes for more than 100 years, there is still an ambiguity concerning asphaltene …

Practical Methods For Source Separation In Emc Measurements, Yuanzhuo Liu

Masters Theses

"Electromagnetic emission is critical in the electronic industry with the rapid growth of the development of the electronic device. To identify the emission from the multipule sources, two methods are proposed in the near field scan and total radiated power measurement respectively.

The first method can be applied in the measurement of the field generated by multiple non-correlated sources. The contribution of each source is determined using a blind source separation (BSS) technique. The measurements are performed using one scanning probe and stationary reference probes, avoiding the need to measure the spatial correlations of the random field. The resolving result …

Design And Implementation Of Applications Over Delay Tolerant Networks For Disaster And Battlefield Environment, Karthikeyan Sachidanandam

Masters Theses

"In disaster/battlefield applications, there may not be any centralized network that provides a mechanism for different nodes to connect with each other to share important data. In such cases, we can take advantage of an opportunistic network involving a substantial number of mobile devices that can communicate with each other using Bluetooth and Google Nearby Connections API(it uses Bluetooth, Bluetooth Low Energy (BLE), and Wi-Fi hotspots) when they are close to each other. These devices referred to as nodes form a Delay Tolerant Network (DTN), also known as an opportunistic network. As suggested by its name, DTN can tolerate delays …

Detection Of Beta-Lactamase Variants In Municipal Wastewater And Fresh Water, Sunil Pandey

Masters Theses

The occurrence and spread of antibiotic-resistant genes (ARGs) are pressing public health problems worldwide. A key factor contributing to the spread of ARGs is lateral gene transfer. Wastewater treatment plants (WWTPs) are measured hot spots of microbial diversity and resistance because they receive polluted wastewater from diverse sources and contain a variety of different environments with dense bacterial loads. Due to the overuse of antibiotics the genetic capacities of microbes have profited. This helps every source of resistance gene and every means of horizontal gene transmission to develop the multiple mechanism of resistance to each antibiotic used clinically, agriculturally, or …

Construct Validity Of The Teate Depression Inventory (Tdi) With A Middle Eastern/Arab American Sample, Dalia Bunni

Masters Theses

The purpose of the study was to examine the construct validity of a newer test used to measure depressive symptoms, the Teate Depression Inventory (TDI). The primary focus of the study was on Middle Eastern/Arab Americans (ME/AA). Previous research has demonstrated that ethnic minority groups may experience and present internalizing disorders, such as depression and anxiety differently than the majority ethnic group, White/Caucasian (W/C) individuals. Further, research suggests that there is a disparity in mental health care among ethnic minority groups, starting with detecting and diagnosing mental health disorders. Inaccurate detection and diagnoses informs inaccurate treatment, further creating a disparity. …

A Pipeline For Exogenous Gene Expression And Biomass Analysis In Plants, Bijay Bisunke

Masters Theses

Biological pretreatment of biomass is typically required for the production of liquid biofuels, which are viable alternatives to traditional fossil fuels. While traditional thermomechanical pretreatments are effective at helping to deconstruct lignocellulose, they are often expensive and tend to generate environmentally dangerous waste materials. An alternative to traditional pretreatment strategies is biological pretreatment, which has focused on lignocellulose-degrading organisms, such as white-rot fungi. While direct pretreatment of biomass with white-rot fungi has shown great promise, directly expressing functional white-rot fungi genes in plants (i.e. in planta expression) has the potential to be even more efficient because the biomass itself …

Context Dependency Of Invasion Impacts On The Controllers Of Invasibility In Microstegium Vimineum, Scott Vincent Janis

Masters Theses

Although plant invasions are of major conservation concern, understanding of the natural controls on invasion and their impacts is largely limited to static observational studies or artificially manipulated systems. Linking patterns of invasion with subsequent impacts in natural systems is necessary to fully assess invasion causes and consequences. Therefore, I employed a long-term approach to sequentially assess the controls on invasion and their subsequent impacts in a self-assembled system for the highly invasive annual grass Microstegium vimineum. I modeled likely factors contributing to the probability of invasion and local invasion success of a natural invasion of M. vimineum in a …

The Impact Of Academic Enablers Instruction On Academic Achievement Of Elementary School Children, Bryce Kirk

Masters Theses

The present study investigated the relationship between Academic Enablers (AEs) instruction and student achievement. Specifically, whether such behaviors and attitudes explicitly taught in a small group setting would improve students' academic performance. Students struggle academically and behaviorally for a variety of reasons, poor or lack of instruction, lack of motivation, or related to a disability, to recognize a few. Existing literature has identified several factors, (e.g., interpersonal/social skills, motivation, study skills, and engagement), known as AEs, that meaningfully contribute toward students' academic success. However, unlike previous studies that focused on such AEs in isolation, this study addressed this limitation and …

What We Expected From National Socialism: Hermann Rauschning And Danzig's Lnterwar Radical Right (1918-1942), Nima Lane

Masters Theses

This project uses Dr. Hermann Rauschning as a case study to analyze the transformation of the German intellectual right, stretching from his early career in the Weimar Era to the post-1945 era. Rather than offer a purely narrative biography, this study uses the figure of Rauschning to examine the fate of the German right from the Kaisserreich to the aftermath of World War II. Rauschning, born in 1887, was both a political and intellectual figure. However, these aspects of Hermann Rauschning are not necessarily separate. Although some historians see Hermann Rauschning as unique, I argue that he is in fact …
