Variation In Leaf Morphology Of An Alpine Shrub Community Along Environmental Gradients, Abdulssalam Khafsha

Masters Theses

Mountains represent complex environment gradients which strongly affect local temperature regimes and rainfall. These changes in climate conditions drive a diversity of plant responses. As alpine environments are expected to change dramatically in response to climate change, understanding plant responses to environmental variation is critical in these environments. Although they are a critical component of alpine communities, the environmental responses of shrubs have been much less examined than trees, representing an important knowledge gap. Leaves, as the primary photosynthetic organs on plants, would be expected to respond strongly to local climate conditions. In this study, I documented how the leaf …

Haplotype Diversity And Population Genetic Structure Of Antistrophus Gall Wasps Associated With Two Silphium Species And Implication For Host Mediated Speciation, Jiaxin Deng

Masters Theses

Gall making insects form a special feeding guild of phytophagous animals, and by manipulating host plant tissue differentiation, are able to avoid plant chemical defenses and thus have no need for counter defense mechanisms. Host plant selection is crucial to the evolution of these insects because successful gall formation is largely dependent on host plant ability to respond to stimuli. In Illinois and neighboring states, Antistrophus gall wasps associated with the rosin weed (S. integrifolium) and the cup plant (S. perfoliatum) are morphologically indistinguishable and thus have been treated as belonging to single species. However, the wasps from the host …

The vector autoregressive model (VAR) has been adopted to estimate the long run causal relationship among exports, foreign direct investment and GDP. Results for the cointegration test show that there exists a long run equilibrium relationship among exports, FDI and GDP. The estimated Error Correction Model finds FDI negatively affecting exports with a two-year gap. Our findings …

Social Anxiety And Fear Of Evaluation In Middle Schoolers, Leslie Hunt

Masters Theses

Social anxiety can have a significant effect on adults and adolescents alike, causing significant distress and impairment. Fear of negative evaluation has been found to be positively correlated to social anxiety in adults and adolescents. Thus, an individual who has social anxiety tends to worry that they will be judged negatively by others in social situations. More recently, fear of positive evaluation also has correlated positively to social anxiety in adults (Weeks, Heimberg, & Rodebaugh, 2008); thus, adults with social anxiety tend to also fear when they are given positive feedback, such as a compliment. This study examines the links …

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 …
