Application And Comparison Of Geomorphological And Hydrological Pool And Riffle Quantification Methods, Amy M. Krueger, Kelly M. Frothingham

The Geographical Bulletin

Pools and riffles have long been recognized as fundamental geomorphological elements of meandering streams. As such, the quantification of pool and riffle characteristics and development of techniques to identify these bed forms has been an important research field for decades. The definition and identification of pools and riffles, however, can vary amongst disciplines. This research compares methods used in two different disciplines, geomorphology and hydrology, and determines the level of agreement between them. Initially, we identified pools and riffles using the bed differencing technique (bdt) in fifteen reaches of Ransom Creek, Clarence, New York. We then calculated the hydrological index, …

An All-Hazards Approach To Us Military Base Camp Site Selection, Mark Corson, Christopher Jasperro

The Geographical Bulletin

Throughout history, military forces have built encampments and bases in hostile areas to defend and sustain themselves while on campaign. The predominant criteria for site selection were and continue to be tactical and logistical concerns. This article applies a geographic perspective to US military base camp site selection in contingency operations such as Bosnia, Kosovo, Iraq, or Afghanistan. In particular, it argues that an all-hazards approach should be employed in the site selection process, and that the all-hazards approach be an integral part of the planning phase of base camp development and emerging site selection doctrine. This project begins with …

Ecological Marginalization And Hill Tribe Security In Northern Thailand, Richard A. Crooker

The Geographical Bulletin

In recent decades, Thai elites have ecologically marginalized hill tribe farmers in northern Thailand. A region-wide population boom has fueled a ‘land grab’ by the elites and forced hill tribe farmers to live on less land with few off-farm options. The marginalized farmers are less secure in their livelihoods, and as a result, there has been conflict over resources between them and governmental authorities and ethnic Thais. This paper analyzes the hill tribes’ marginalization in order to assess the risk of heightened social conflict in the region. I chose hill tribe villages in the Mae Sa Valley as a “best-case” …

Tunable Blended Collagen I/Ii And Collagen I/Iii Hydrogels As Tissue Mimics, Paulina M. Babiak, Carly M. Battistoni, Leonard Cahya, Rithika Athreya, Jason Minnich Ii, Alyssa Panitch, Julie C. Liu

School of Chemical Engineering Faculty Publications

Collagen (Col) is commonly used as a natural biomaterial for biomedical applications. Although Col I is the most prevalent col type employed, many collagen types work together in vivo to confer function and biological activity. Thus, blending collagen types can better recapitulate many native environments. This work investigates how hydrogel properties can be tuned through blending collagen types (col I/II and col I/III) and by varying polymerization temperatures. Col I/II results in poorly developed fibril networks, which softened the gels, especially at lower polymerization temperatures. Conversely, col I/III hydrogels exhibit well-connected fibril networks with localized areas of fine fibrils and …

Tanzania Journal of Science

The use of improved beehives in beekeeping is emphasized to facilitate easier colony manipulations. The improved beehives used in Tanzania are either imported or manufactured locally by adopting dimensions for European honey bees. However, the dimensions adopted are faulty to the dimensions of local honey bees, leading to problems such as cross-combing which hinder realization of the expected management advantages. This study assessed the characteristic natural bee space and comb cell dimensions of honey bee colonies occupied the traditional split log hives in Mwinkantsi village, Babati district. Results showed that honey bee colonies in Mwinkantsi village exhibited an overall bee …

Navigating Past The Tragedy Of The Commons, Maximilian Theriot, Walter E. Block

Journal of New Finance

Privatization of environmental resources is a promising approach for mitigating the tragedy of the commons. The present paper focuses on the impact and theoretical underpinnings of privatization within economic structures. The first part lays out a strong ethical case against state ownership, rooted in the belief that the state's claim to ownership inherently involves coercion, which likens taxation to theft due to its compulsory nature. The second part provides evidence that privatization leads to enhanced profitability and efficiency across sectors. The third part discusses the necessity of robust corporate governance and legal reforms post-privatization to ensure environmental protections are not …

Mutation In Prkra Results In Cerebellar Abnormality And Reduced Elf2Α Phosphorylation In A Model Of Dyt-Prkra, Samuel B. Burnett, Allison M. Culver, Tricia A. Simon, Taylor Rowson, Kenneth Frederick, Kristina Palmer, Stephen A. Murray, Shannon W. Davis

Faculty Publications

Variants in the PRKRA gene, which encodes PACT, cause the early-onset primary dystonia DYT-PRKRA, a movement disorder associated with disruption of coordinated muscle movements. PACT and its murine homolog RAX activate protein kinase R (PKR; also known as EIF2AK2) by a direct interaction in response to cellular stressors to mediate phosphorylation of the α subunit of eukaryotic translation initiation factor 2 (eIF2α). Mice homozygous for a naturally arisen, recessively inherited frameshift mutation, Prkra^lear-5J, exhibit progressive dystonia. In the present study, we investigated the biochemical and developmental consequences of the Prkra^lear-5J mutation. Our results indicated that the …

Faculty, Staff and Student Publications

Starting in the 1970s, individuals, businesses and the public have increasingly benefited from policies prohibiting smoking indoors, saving thousands of lives and billions of dollars in healthcare expenditures. Smokefree policies to protect against secondhand smoke exposure, however, do not fully protect the public from the persistent and toxic chemical residues from tobacco smoke (also known as thirdhand smoke) that linger in indoor environments for years after smoking stops. Nor do these policies address the economic costs that individuals, businesses and the public bear in their attempts to remediate this toxic residue. We discuss policy-relevant differences between secondhand smoke and thirdhand …

Low-Frequency Stimulation Of Corpus Callosum Suppresses Epileptiform Activity In The Cortex Through Γ-Aminobutyric Acid Type B Receptor And Slow Afterhyperpolarization-Mediated Reduction In Tissue Excitability, Nrupen Pakalapati, Chia Chu Chiang, Dominique M. Durand

Faculty Scholarship

Objective: Deep brain stimulation, particularly low-frequency stimulation (LFS) targeting fiber tracts, has emerged as a potential therapy for drug-resistant epilepsy (DRE) and for generalized epilepsy, both of which pose significant treatment challenges. LFS diffusely suppresses seizures in the cortex when applied to fiber tracts like the corpus callosum (CC). Nevertheless, the specific processes responsible for suppressing epileptic activity in the cortex induced by LFS remain unclear. This study investigates the mechanisms underlying the antiepileptic effect in the cortex of LFS of the CC in coronal rodent brain slices. Methods: An in vitro 4-aminopyridine (4-AP) seizure model of cortical seizures was …

Glucose Metabolism Controls Monocyte Homeostasis And Migration But Has No Impact On Atherosclerosis Development In Mice, Alexandre Gallerand, Gyu Seong Heo, Hannah Luehmann, Yongjian Liu, Et Al.

2020-Current year OA Pubs

Monocytes directly contribute to atherosclerosis development by their recruitment to plaques in which they differentiate into macrophages. In the present study, we ask how modulating monocyte glucose metabolism could affect their homeostasis and their impact on atherosclerosis. Here we investigate how circulating metabolites control monocyte behavior in blood, bone marrow and peripheral tissues of mice. We find that serum glucose concentrations correlate with monocyte numbers. In diet-restricted mice, monocytes fail to metabolically reprogram from glycolysis to fatty acid oxidation, leading to reduced monocyte numbers in the blood. Mechanistically, Glut1-dependent glucose metabolism helps maintain CD115 membrane expression on monocytes and their …

We review the functioning and sustainability of coastal marshes and mangroves. Urbanized humans have a 7,000-year-old enduring relationship to coastal wetlands. Wetlands include marshes, salt flats, and saline and freshwater forests. Coastal wetlands occur in all climate zones but are most abundant in deltas. Mangroves are tropical, whereas marshes occur from tropical to boreal areas. Quantification of coastal wetland areas has advanced in recent years but is still insufficiently accurate. Climate change and sea-level rise are predicted to lead to significant wetland losses and other impacts on coastal wetlands and the humans associated with them. Landward migration and coastal retreat …

Determination Of A New Spring-Flying Species Of The Pterourus Glaucus Complex (Papilionidae) In Southern New England, Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

The Pterourus glaucus complex in three southern New England states is analyzed for cryptic speciation. What was historically considered to be one species, P. glaucus (Linnaeus, 1758), was recently split to separate P. canadensis (Rothschild & Jordan, 1906) at species rank (Hagen et al., 1991). Additionally, P. appalachiensis Pavulaan & Wright, 2002, was described as an Appalachian Mountain endemic. The western member of the complex, P. rutulus (Lucas, 1852), has frequently been considered a subspecies of P. glaucus (Scott, 1986; Tyler, Brown & Wilson, 1994), as was P. alexiares (Höpffer, 1866) (Tyler, Brown & …
