The Challenge Of Crafting And Maintaining Democracy In Zimbabwe And South Africa, Robert W. Compton Jr.

Journal of African Policy Studies

This paper examines the impact of land reform policies on the political development of South Africa and Zimbabwe. In particular, it focuses on the past policy approaches to land reform, principally the "willing seller and able buyer" market approach in the context of past injustices involving land reform. The politics of land reform and the inability of the hegemonic parties in South Africa and Zimbabwe, the African national Congress (ANC) and Zimbabwe African National Union (ZANU) respectively, to implement satisfactory policy contributes to negative political and economic consequences for both countries. Simultaneously, opposition parties in both countries, in particular the …

The Future Of Monetary Integration In Southern Africa: Lessons From The European Union?, Richard Dutu, Donald L. Sparks

Journal of African Policy Studies

The 14-member Southern African Development Community (SADC) has a long-term goal of becoming a full common market. A major component of fuller integration would be a common currency arrangement. The states of southern Africa, however, face a dilemma: While the region already sustains a successful and long-running monetary union, the Common Monetary Area (CMA, known as the "Rand Zone"), the region's leading economic integration organization, the SADC, is opposed to joining the union.

The Common Market for East and Southern Africa (COMESA)—a less successful, but rival economic organization—favors, for its part, a monetary union. Is the SADC ready for monetary …

Smes In Developing Countries And The Problem Of Exporting: Market Entry Costs, Exchange Rate Shocks And The Capital Structure Of Firms, Trond-Arne Borgersen

Journal of African Policy Studies

This paper integrates a sunk-cost model of foreign trade with a discussion on the capital structure of small and medium-sized enterprises (SMEs) in developing countries. A model of foreign trade where firms have to incur irrecoverable market entry costs in international markets is presented. As a result of the market entry costs the foreign trade structure is non-linear. This non-linearity complicates the relationship between foreign trade flows and exchange rates, compared to the predictions of conventional foreign trade theory. Both the entry and the operating decision are affected, as the non-linearity puts pressure on the capital structure of firms. In …

300-900 Mhz Midband Array Design For The Lunar Farside Technosignatures And Transients Telescope, Daniel A. Kemp, Jamie A. Frei, Caleb S. Edmunds, Karl F. Warnick

Utah Space Grant Consortium

The Lunar Farside Technosignature & Transients Telescope (LFT3), planned as an ultra-high frequency (UHF) phased array near the lunar antipode, is introduced as a pioneering mission capitalizing on recent advancements in analog beamforming. LFT3's midband array specifically leverages a described analog beamformer to achieve critical baseline measurements, enabling observations of astrophysical phenomena free from terrestrial interference. The authors describe the development of a wideband, low-power analog beamformer suitable for lunar-based radio astronomy, evaluating the primary architectures: a combiner tree, Rotman lens, Butler matrix, Nolen matrix, and Blass matrix. Each approach is analyzed in terms of performance, complexity, reliability, and suitability …

Multiple Wavepacket Decomposition Of F404 Engine Military Jet Noise, Tyce W. Olaveson, Kent L. Glee

Utah Space Grant Consortium

Jet noise sources are challenging to measure directly due to the extreme environment. Inverse methods, such as acoustic beamforming, using data collected near these sources can be used to construct equivalent source models that accurately describe the acoustic radiation. However, generating these models for a complex source can require thousands of parameters for a complete description. To address this challenge, a multiple wavepacket decomposition is introduced, reducing the source model into a set of analytic wavepackets, which recreate the full-rank model. This paper provides an overview of the decomposition procedure and applies it to acoustic data collected near a T-7A-installed …

A Comparison Of Surrogate Modeling Techniques For Predicting Radial Turbomachinery Flow Fields, Chase Oliphant

Utah Space Grant Consortium

Radial pumps and compressors are used in various engineering applications, including rocket turbopumps, automotive turbochargers, refrigeration systems, etc. Several different physical effects, including viscous losses, flow separation, compressibility, and rotational dynamics, dominate the flow in a radial impeller. These effects make predicting the flow field in a radial impeller very difficult, requiring computationally expensive CFD. However, a majority of an individual flow field calculated using CFD is often not pertinent to a designer, who only requires information at certain positions within the flow field. This often results in most of the simulation data generated being unused. Accurately predicting the flow …

Bistatic Continuous Wave Radar Using Sdrs, Matthew Finger

Utah Space Grant Consortium

This paper describes a research project at Weber State University (WSU) to create a small-scale passive-bistatic radar (PBR) using a low-cost software-defined-radio (SDR). SDRs have improved (in terms of performance versus cost) to where an affordable, low-power, receive-only radar system may be used in suitable RF environments.

The initial effort will generate a PBR testbed. Controlled measurement campaigns will validate radar-signal processing algorithms using two-dimensional geometries with a controllable transmitted signal. Follow-on research will integrate a two-element phased-array antenna at the receive SDR.

Using Nasa Awe Observations To Investigate The Global Distribution Of Concentric Gravity Waves, Anastasia King-Brown, Ludger Scherliess

Utah Space Grant Consortium

Upward propagating atmospheric gravity waves (GWs) originating from various lower atmosphere sources can transport energy and momentum into the Earth's upper atmosphere. In the ionosphere, GWs produce traveling ionospheric disturbances (TIDs), generate electric fields, and appear to contribute to the seeding of equatorial plasma bubbles that have detrimental effects on navigation, communication, and surveillance systems. Despite their importance and decades of research there are still many open questions regarding the morphology and dynamics of gravity waves. Of particular interest are concentric gravity waves (CGWs), as they are the direct result of the coupling between lower and upper atmosphere . For …

Nitrogen Form Determines Lettuce Yield In Continually Replanted Systems, Noah J. Langenfeld, Bruce Bugbee

Utah Space Grant Consortium

Nitrogen (N) recycling is essential in closed root-zones for bioregenerative life support in crewed missions. Microorganisms recycle organic N forms from human waste into ammonium and nitrate for plant growth. We used lettuce as a model crop to examine yield under multiple N sources modelled from N recycling. Plants were grown in peat moss media adjusted to pH 6 or 7 for five repeated plantings in the same containers without replacing the media. A nutrient solution was used for both studies that contained N as either ammonium nitrate, ammonium, nitrate, urea, or microbial biomass from the N-fixing microorganism Azotobacter vinelandii …

Al-Mustaqbal Journal of Pharmaceutical and Medical Sciences

Brain tumor classification is one of the crucial uses of medical image processing. A longer life is possible if the tumor is correctly and promptly diagnosed. Because manually segmenting brain tumors for cancer diagnosis is difficult and time-consuming, automatic classification of brain tumor images is necessary for this task. Pre-processing, feature extraction, feature selection, and classification are the four stages of the general framework for automatic tumor detection from MRI images. The method for automatic brain tumor classification described in this research combines machine learning and deep learning algorithms. We used three pre-trained deep networks to extract the most detailed …

A Simple Sonication Method For Generating Monodispersed Nanoparticles Of Hydrophobic Antioxidants, Kyle Jackson, David Britt, Yu Huang

Utah Space Grant Consortium

Various hydrophobic antioxidants remain unexplored for the treatment of space radiation and oxidative stress due to their inability to enter the cell without a drug delivery vehicle as their surface properties cause them to suffer from a poor solubility. In this paper you will find a recent breakthrough of a new method to create neat antioxidant nanoparticles free of any surfactant whatsoever vastly improving inherent solubility. These nanoparticles are synthesized monodispersed with a low polydispersity. This is even more suitable for astronauts then other generation methods, as the cocktail is without any solvent or surfactant which can have unknown effects …

Biosignature Analysis In Saline Environments Using The Microfluidic Organic Analyzers For Biosignatures (Moab), Andrew Pack, Parker Jenkins, Jungkyu (Jay) Kim

Utah Space Grant Consortium

This study examines amino acid stability in high-salinity environments to enhance biosignature detection technologies. Using both absorption spectroscopy and capillary electrophoreses (CE), we investigated the survivability of valine and serine in laboratory-created brines simulating those found on celestial bodies throughout the solar system. Our findings reveal a protective effect of brines on amino acids, with reduced degradation rates compared to control samples containing no salts. During the 12-day observation period, both polar and non-polar amino acids showed enhanced stability in high-salinity environments, though non-polar amino acids exhibited more pronounced benefits from this protective effect. Valine concentrations in saline conditions decreased …
