Unhinged: Kairos And The Invention Of The Untimely, Robert Leston

Publications and Research

Traditionally, kairos has been seen as a “timely” concept, and so invention is said to emerge from the timeliness of a cultural and historical situation. But what if invention was thought of as the potential to shift historical courses through the injection of something new or alien into a situation? This essay argues that kairos has not been able to free itself from its historical constraints because it has been bound to a human sense of temporality. By evolving along patterns different from print, the apparatus of the cinema developed in a way where it was not bound to illustrating …

Research About Low Permeability Measurement, Jun He

Theses and Dissertations

Petroleum exploration and production from shale formations have gained great attention throughout the world in the last decade. Producing the hydrocarbons from shale is challenging because of the low porosity and permeability. It is imperative to investigate permeability of the shale formations in order to better understand the performance of wells that are producing hydrocarbons from shale. Permeability is also one of key parameters in modeling fluids flow in matrix in reservoir simulation. Due to the low or very low permeability, the measurement of permeability is time consuming and expensive. These factors often limited the ability to perform permeability measurement …

Many studies have used data collected from field observations, while other studies relied solely on computer modeling. This Dissertation research used a spatial analysis approach, which has been less widely employed, to investigate neighborhood level biophysical, built environmental and socio-demographic determinants of the El Paso and Juárez UHI. The research utilized inexpensive data obtained from US and …

Geomechanics And Elastic Anisotropy Of The Bakken Formation, Williston Basin, Mehdi Ostadhassan

Theses and Dissertations

Many of the earth’s rocks exhibit anisotropic characteristics. Anisotropy is particularly common in many sedimentary rocks, such as shales. Anisotropy is defined as the spatial alignment of mineral grains, layers, fractures and stresses which causes elastic wave velocity and other elastic properties to vary with direction. There are two types of anisotropy: intrinsic and stress-induced. Intrinsic anisotropy is caused by beddings, microstructures or aligned fractures formed during deposition. Stress-induced anisotropy is caused by strain associated with external stresses. Intrinsic anisotropy originates in the absence of external stresses, while stress-induced anisotropy results from tectonic and overburden stresses. The style of earth …

Knowledge, Perceptions, Discrimination, Health Self-Efficacy, And Risky Behaviors For Hiv/Aids And Its Association With Migration Time Among Mixtec And Zapotec Men Who Migrate, 2012, Sandra Iveth Bejarano

Open Access Theses & Dissertations

BACKGROUND AND SIGNIFICANCE: Historically, there has been a transnational migration flow from Mexico to the United States. There are many reasons for which people make the decision to migrate; the most common ones are unemployment and economic hardship. Currently, Oaxaca is considered one of the states with the highest poverty levels in Mexico. As a result of extreme poverty groups of indigenous people, such as Zapotec and Mixtec, are forced to migrate out of their communities in order to find jobs. Migration has been associated with various health outcomes, including diabetes, high blood pressure, and heart disease as well as …

Preparation Of Cobalt/Nickel Molybdenum Sulfide Catalysts Supported By Aqueous Media Soluble Multi-Wall Carbon Nanotubes., Hassan Ahmad Bleibel

Open Access Theses & Dissertations

Multi-walled carbon nanotubes (MWCNTs) have been subjected to chemical treatment in order to introduce hydrophilic functional groups on their surfaces. These covalently bonded groups did enhance the solubility of MWCNTs in aqueous media as expected. Functionalized MWCNTs were characterized using FTIR, Raman spectroscopy, TGA, X-ray diffraction, dispersion test and TEM. Then, functionalized MWCNTs were incorporated in the hydrothermal synthesis method of transition metal sulfide catalysts (CoMo, NiMo, and Ethylenediamine-CoMo Sulfides). Catalysts were characterized using X-ray diffraction, TEM, SEM, N2 Gas adsorption-desorption, elemental analysis, and Hydrodesulfurization (HDS) reaction of dibenzothiophene (DBT). The objective was to study the functionalized MWCNTs' effect; being …

Routes Of Compromise: Road Building And Motor Transportation In Modern Mexico, 1920-1952, Michael K. Bess

Open Access Theses & Dissertations

"Routes of Compromise" studies the creation and function of the government bureaucracy that built motor roads and highways, and the everyday impact of those roadways on public life in Mexico. It covers roughly thirty years of construction efforts from 1920 to the early 1950s as foreign and domestic actors, working at the transnational, national, state, and local levels, established a series of policy and investment programs that became the primary model for infrastructure development in Mexico during the mid-twentieth century. Road building offers a unique perspective to the study of Mexican state formation, underscoring how the national government sought to …

Seismic Reflection Exploration Of Geothermal Reservoir Atnaval Air Station (Nas) Fallon, Nevada, Alay Ghebremariam Gebregiorgis

Open Access Theses & Dissertations

The Primary objective of this study is to increase geologic and tectonic understanding of the geothermal resources at the Naval Air Station (NAS) Fallon, Nevada. The seismic reflection method is employed to study faults, fractures and other tectonic structures in the subsurface in order to identify geothermal drill targets. The efficiency of geothermal systems is strongly dependent on water circulation. Discrete faults may be permeable and provide pathways for water flow depending on the fracture density. It is therefore desirable to detect and map faults and fracture zones and characterize their physical properties when evaluating a geothermal prospect.

The seismic …

Chapter 5 Biotic Interactions And Temporal Patterns Forlandslide Ecology, Lawrence R. Walker, Aaron B. Shiels

United States Department of Agriculture Wildlife Services: Staff Publications

1. Landslide succession is the sequential replacement of plant communities following landslide creation. It is affected by biotic interactions and abiotic conditions and occurs in the intervals between recurrent erosion events.

2. Plant species can facilitate or inhibit landslide succession by direct species interactions or indirectly by the alteration of resources including light levels, soil stability, soil moisture, or soil nutrients. Species replacements may also occur due to differences in the life histories of landslide colonizers.

3. Herbivores, pathogens, and non-native species influence landslide succession and contribute to the variety of successional trajectories found on landslides, potentially with long-term consequences. …

Chapter 2 Spatial Patterns For Landslide Ecology, Lawrence R. Walker, Aaron B. Shiels

United States Department of Agriculture Wildlife Services: Staff Publications

1. Remote sensing tools have greatly improved the mapping of both terrestrial and submarine landslides, particularly at global scales. At regional and local scales, environmental correlates are being found that help interpret spatial patterns and related ecological processes on landslides.

2. Landslides are frequent on only 4% of the terrestrial landscape and coverage varies over time because new landslides do not occur at a constant rate.

3. Multiple landslides triggered by the same event, such as an earthquake or severe rainstorm, can vary in physical characteristics. This variety contributes to a mosaic of landslide conditions across the landscape.

4. A …

Wildlife In Airport Environments: Chapter 9 Managing Airport Stormwater To Reduce Attraction To Wildlife, Bradley F. Blackwell, David Felstul, Thomas W. Seamans

United States Department of Agriculture Wildlife Services: Staff Publications

An airport is a component of the landscape, contributing to and subject to local- and landscapelevel factors that affect wildlife populations and the hazards that these species pose to aviation (Blackwell et al. 2009, Martin et al. 2011). Water resources at and near an airport, in the form of both surface water and contained runoff, are recognized by the Federal Aviation Administration (FAA) as potential attractants to wildlife that pose hazards to aviation safety (FAA 2007). Surface water, including aboveground stormwater detention/retention facilities (see U.S. Environmental Protection Agency 2006), can represent a substantial proportion of the area within siting criteria …

Wildlife In Airport Environments: Chapter 8 Identification And Management Of Wildlife Food Resources At Airports, Travis L. Devault, Brian E. Washburn

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife use airport habitats for a variety of reasons, including breeding, raising young, resting, taking refuge from predators, and locating sources of water. But the chief motivation for most individuals to encroach on airports is food. Depending on the specific habitat types present and habitat management strategies employed, airports can harbor large numbers of small mammals, insects, earthworms, and palatable vegetation that attract many species hazardous to aircraft. Often the best way to reduce populations of hazardous wildlife at airports is to determine which sources of food are being used, and then remove or modify those foods to make them …

Fixing Copyright In Three Impossible Steps: Review Of How To Fix Copyright By William Patry, Mark P. Mckenna

Journal Articles

This review of William Patry’s How to Fix Copyright highlights three of Patry's themes. First is Patry’s insistence that copyright policy be based on real-world evidence, a suggestion that should be uncontroversial but instead runs headlong into the near-religious commitments of copyright stakeholders. Second is Patry’s emphasis on the difference between the interests of creators, on the one hand, and owners of copyright interests, on the other. Third, and finally, is Patry’s focus on the copyright system’s strong tendency to entrench business models and resist change, particularly in the face of new technology.

Perception And Decision At The Threshold Of Tort Law: Explaining The Infrequency Of Claims, David M. Engel

Journal Articles

Although numerous studies have confirmed that tort victims rarely litigate and that most simply "lump" their losses, we lack an understanding of why this should be so. Why do the vast majority of injured persons choose inaction over action? Explanations relying on rational actor theories on the one hand or cultural determinism on the other have been sharply challenged by recent studies of mind, culture, and cognition, particularly with respect to individual responses to physical trauma and disablement. This article, drawing on a broad interdisciplinary literature dealing with injury victims, proposes a new model of perception and decision by persons …
