Higher Education Experiences Of International Faculty In The U.S. Deep South, Elizabeth Omiteru, James Martinez, Rudo Tsemunhu, Eugene F. Asola

Journal of Multicultural Affairs

Immigration was one of the key issues from within the Obama administration. One focus of the administration was to retain brilliant foreign scholars who have studied in the United States (U.S). Rather than let International Faculty return to their countries after completing their programs, employers found it advantageous to retain these professionals to boost the United States workforce. Higher education was one of the government sectors that experienced an increase in the numbers of foreign nationals choosing to remain in the United States after completing their degrees. What many International Faculty may be oblivious of, and which their programs of …

The purpose of this article is to provide a framework for engineering education …

Assessing Mechanistic Reasoning: Supporting Systems Tracing, Paul J. Weinberg

Journal of Pre-College Engineering Education Research (J-PEER)

Reasoning about mechanism is central to disciplined inquiry in science and engineering and should thus be one of the foundations of a science, technology, engineering, and mathematics education. In addition, mechanistic reasoning is one of the core competencies listed in the Next Generation Science Standards (NGSS) Engineering Concepts and Practices (NGSS Lead States, 2013). Mechanistic explanations focus on the processes that underlie cause–effect relationships and consider how the activities of system components affect one another.

While some assessment work has been accomplished in engineering education, to date mechanistic reasoning is an area where limited assessment development has been accomplished for …

Ways Of Rational Enhancements Of Passage And Transportable Ability On Railways Jsc "Uty", S.K. Xudayberganov, A.A. Svetashev, Sh.Sh. Kayumov

Journal of Tashkent Institute of Railway Engineers

The constant increase in the number of passenger trains has led to the fact that the semi-automatic blocking does not cope with the timely passing trains through the section. This article discusses the carrying capacity of railway section "N-B". The reserve capacity of this section is practically absent, the removal rate of passenger trains increases, which negatively affects the work of the entire railway section. Disposable and required carrying debility is determined. The method of increasing the capacity is chosen for each line depending on the given dimensions of movement, local conditions and technical and economic efficiency of different options.

Transport Logistics Of Transit Potential Of “Uzbekistan Temir Yullari” Jsc, U.N. Ibragimov, O.T. Aliyev, M.M. Tohirov

Journal of Tashkent Institute of Railway Engineers

Uzbekistan occupies an important geostrategic position in Central Asia, through the territory of which the Great Silk Road, where numerous trade routes converged, was in ancient times, and an intensive process of mutual enrichment of the cultures of the peoples of the world was under way. And today, there are crossroads of transport routes leading from the East to the West, from the South to the North. For us, the task of preserving a place in international transport with the purpose of developing the efficiency of transportation must be urgent.

Growing In The Womb: The Effect Of Seismic Activity On Fetal Growth, Rocío Álvarez-Aranda, Serafima Chirkova, José Gabriel Romero

Fondazione Eni Enrico Mattei Working Papers

We study how prenatal maternal stress, caused by sustained seismic activity, affects birth outcomes in Chile during the period 2011-2015. A mother-fixed-effect model together with the spatiotemporal variation of earthquakes in Chile allow us to deal with identification issues that have obscured previous estimates. Our findings show that prenatal maternal stress seems to affect fetal growth, because infants born to mothers exposed to earth tremors in early and/or mid gestation are more likely to be large for gestational age. The estimates suggest that relatively poorer Chilean mothers are more vulnerable to earthquakes, because their babies seem to drive the reported …

Capital Accumulation, Green Paradox, And Stranded Assets: An Endogenous Growth Perspective, Wei Jin, Zhongxiang Zhang

Fondazione Eni Enrico Mattei Working Papers

The existing studies on Green Paradox and stranded assets focus on dirty exhaustible assets (fossil fuel reserves) and show that environmental regulations, by changing the costs of dirty inputs relative to clean ones, lead to replacements of the former by the latter and stranding of dirty assets due to perfect substitution. It, in turn, induces acceleration of dirty resource extractions and pollution emissions for fear of dirty assets becoming stranded - the Green Paradox effect. This paper uses an endogenous growth framework to revisit the problem of Green Paradox and stranded assets by taking a new perspective that focuses on …

Nano-Based Systems And Biomacromolecules As Carriers For Metallodrugs In Anticancer Therapy, Mina Poursharifi, Marek T. Wlodarczyk, Aneta J. Mieszawska

Publications and Research

Since the discovery of cisplatin and its potency in anticancer therapy, the development of metallodrugs has been an active area of research. The large choice of transition metals, oxidation states, coordinating ligands, and different geometries, allows for the design of metal-based agents with unique mechanisms of action. Many metallodrugs, such as titanium, ruthenium, gallium, tin, gold, and copper-based complexes have been found to have anticancer activities. However, biological application of these agents necessitates aqueous solubility and low systemic toxicity. This minireview highlights the emerging strategies to facilitate the in vivo application of metallodrugs, aimed at enhancing their solubility and bioavailability, …

Communication, Democracy, And Intelligentsia, Dmitri N. Shalin

Sociology Faculty Research

In the early 1990s, a group of Russian and American scholars teamed up to investigate the impact of Gorbachev’s reform on Soviet society, focusing especially on the role the intelligentsia played in fomenting glasnost and perestroika. Results of this collaborative study were published in a volume Russian Culture at the Crossroads: Paradoxes of Postcommunist Consciousness (Shalin, 1996a). The contributors worked on the assumption that perestroika was an irreversible achievement, that distortions the reforms wrought in Russian society would be smoothed out over time. Today, this assumption appears overoptimistic. After nearly twenty years in power, Vladimir Putin dismantled key democratic institutions, …

Mechanical Suppression Of Osteolytic Bone Metastases In Advanced Breast Cancer Patients: A Randomised Controlled Study Protocol Evaluating Safety, Feasibility And Preliminary Efficacy Of Exercise As A Targeted Medicine, Nicolas H. Hart, Daniel A. Galvão, Christobel Saunders, Dennis R. Taaffe, Kynan T. Feeney, Nigel A. Spry, Daphne Tsoi, Hilary Martin, Raphael Chee, Tim Clay, Andrew D. Redfern, Robert U. Newton

Research outputs 2014 to 2021

BACKGROUND: Skeletal metastases present a major challenge for clinicians, representing an advanced and typically incurable stage of cancer. Bone is also the most common location for metastatic breast carcinoma, with skeletal lesions identified in over 80% of patients with advanced breast cancer. Preclinical models have demonstrated the ability of mechanical stimulation to suppress tumour formation and promote skeletal preservation at bone sites with osteolytic lesions, generating modulatory interference of tumour-driven bone remodelling. Preclinical studies have also demonstrated anti-cancer effects through exercise by minimising tumour hypoxia, normalising tumour vasculature and increasing tumoural blood perfusion. This study proposes to explore the promising …

Vegetation Trends In A Restored Coastal Wetland At Prisoners Harbor, Santa Cruz Island, Channel Islands National Park, Paula J. Power, Marie Denn, Joel Wagner, Mike Martin

Western North American Naturalist

Prisoners Harbor on Santa Cruz Island, California, formerly supported a 5-ha wetland and riparian system, the largest on the California Channel Islands. During the late 1800s ranchers filled in about half of the wetland area in order to support ranching activities. They also rerouted the stream channel to the canyon edge and built an earthen berm along its west bank, which disconnected the stream from its floodplain. The National Park Service developed a wetland and riparian restoration design for Prisoners Harbor based on topographic and hydrologic analyses and on vegetation community depth-to-water-table relationships developed from neighboring reference wetlands. In 2011 …

Geomorphology Of Shell Ridges And Their Effect On The Stabilization Of The Biloxi Marsh, East Louisiana, Frances R. Crawford

LSU New Orleans Theses and Dissertations

Extensive shell ridges frame the edges of marsh platforms in parts of the Biloxi Marsh of southeast Louisiana. The exact sources of the shells in these accumulations have not been clearly identified but the most likely source is a combination of shells from modern offshore and shells excavated from buried St. Bernard delta deposits. Larger or fetch-protected ridges remain stable through time, whereas ridges facing open water are more mobile, moving as much as 38 m inland from July 2017 to January 2018. Behind stable ridges, marsh platform biomass is relatively unaffected. When ridges are mobile, vegetation is smothered, leaving …

Legacy Habitat Suitability Of Eastern Oysters (Crassostrea Virginica) In Louisiana: A Prelude To Mississippi River Delta Freshwater Diversions, Tasia Mv Denapolis

LSU New Orleans Theses and Dissertations

The Louisiana oyster industry is greatly impacted by freshwater and sediment diversions that are part of the effort to restore the state’s coastline. A habitat suitability index (HSI) proposes species-habitat relationships that can be instrumental in creating impact assessments and suitability predictions for management as new diversions are implemented. An oyster (Crassostrea virginica) HSI was developed using three variables crucial to oyster sustainability: average annual salinity, minimum monthly salinity, and average salinity during the spawning season. These Legacy HSI visualizations show annual fluctuations in the distribution of zones suitable for oyster cultivation prior to proposed diversions in Pontchartrain …

Performance Optimization Of The Differential Protection Schemes, Monir Hossain

Current differential protection principle is superior in terms of sensitivity and speed of operation in comparison with other protection principle used in power systems. From the last five decades, various current differential protection schemes are widely used to protect busbars, transformers, and short-transmission lines. The deployment of high capacity microwave and optical fiber technologies redefined

the line protection systems by facilitating the use of current differential protection schemes for long transmission lines. The common application issue of these schemes is mis-operation due to current transformer (CT) saturation during close-in external faults. Moreover, transformer differential protection schemes face mis-trip due to …

The Effects Of Sediment Properties On Barrier Island Morphology And Processes: A Numerical Modeling Experiment, Brittany Kime

LSU New Orleans Theses and Dissertations

Barrier island restoration and nourishment is necessary for sustaining coastal systems worldwide. In the Mississippi River Delta Plain, the lack of sediment supply, relative sea level rise, and reworking of abandoned delta lobes promote rapid disintegration of barriers, which can contribute to mainland storm impacts. Barrier island restorations that utilize higher quality sediments (Outer Continental Shelf- OCS) are expected to exhibit higher resiliency, withstanding coastal erosion, event-induced erosion, and ongoing transgression when compared to barriers nourished using lower quality nearshore (NS) sands. Additionally, use of OCS sediments increases sediment supply by adding material to the system supporting increased barrier longevity …

On The Reversible Effects Of Bias-Stress Applied To Amorphous Indium-Gallium-Zinc-Oxide Thin Film Transistors, Anish Suresh Bharadwaj

Theses

The role of amorphous IGZO (Indium Gallium Zinc Oxide) in Thin Film Transistors (TFT) has found its application in emerging display technologies such as active matrix liquid crystal display (LCD) and active matrix organic light-emitting diode (AMOLED) due to factors such as high mobility 10-20 cm2/(V.s), low subthreshold swing (~120mV/dec), overall material stability and ease of fabrication. However, prolonged application of gate bias on the TFT results in deterioration of I-V characteristics such as sub-threshold distortion and a distinct shift in threshold voltage. Both positive-bias and negative-bias affects have been investigated. In most cases positive-stress was found to have negligible …
