Latest Research: Summary 5. A Review On The Impact Of Climate Change On Food Security And Malnutrition In The Sahel Region Of Cameroon

Journal of Nonprofit Innovation

Climate change has direct and indirect impacts on human health. One indirect impact is food insecurity, which can lead to malnutrition. In the Sahel region of Cameroon, the population regularly experiences high levels of malnutrition, because harsh climate conditions (including extreme drought) have a negative influence on agriculture. In particular, the extreme drought conditions lead to a reduction in agricultural production, an important parameter of food security.

Steering Particles Via Micro-Actuation Of Chemical Gradients Using Model Predictive Control, Mark N. Mcdonald, Cameron K. Peterson, Douglas R. Tree

Faculty Publications

Biological systems rely on chemical gradients to direct motion through both chemotaxis and signaling, but synthetic approaches for doing the same are still relatively naïve. Consequently, we present a novel method for using chemical gradients to manipulate the position and velocity of colloidal particles in a microfluidic device. Specifically, we show that a set of spatially localized chemical reactions that are sufficiently controllable can be used to steer colloidal particles via diffusiophoresis along an arbitrary trajectory. To accomplish this, we develop a control method for steering colloidal particles with chemical gradients using nonlinear model predictive control with a model based …

In this endeavor, students must and will engage with individuals who hold deep convictions of religious faith and affiliation, …

Latest Research: Summary 3. Exploring The Impact Of Climate Change On The Future Of Community-Based Wildlife Conservation

Journal of Nonprofit Innovation

Rural populations with local, small-scale agricultural economies across southern and eastern Africa have adopted community-based conservation (CBC) as their wildlife governance approach. This approach is based on the idea that communities will sustainably govern their wildlife resources when they “receive an enduring interest in and are able control and profit from those resources” (p. 1). The key to the success of this approach is the people within those communities need to believe that the benefit from CBC outweighs the costs associated with living with human-wildlife conflicts (HWC). Human-wildlife conflicts include killing of crops or livestock, destruction of infrastructure, and human …

Dengue Fever In South And Southeast Asia, Mikaela D. Lubin

Ballard Brief

Dengue fever is a mosquito-borne illness that impacts South and Southeast Asia at significant rates. It is carried primarily by the aedes aegypti mosquito, a species that thrives in warm, tropical climates. Features of dengue include excruciating pain and, in severe cases, internal bleeding, shock, and death. The spread of dengue in South and Southeast Asia is due to several factors, including advancements in transportation, poor preventative measures, poor sanitation, and subsequent standing water, which is an ideal breeding ground for mosquitoes. Dengue causes many negative consequences on individuals and communities it affects, including pain and suffering, lasting physiological effects, …

Forgotten Brother Reuben Lewis: Missouri River Fur Trader And Indian Agent For The Arkansas Cherokees, Jay H. Buckley, Deveney Reber

Faculty Publications

Reuben Lewis was born in 1777, the fourth and youngest child of William Lewis and Lucy Meriwether. Their oldest child, Jane, married and lived out her days at Locust Hill, the family estate in Virginia. The Lewis’ second child, baby Lucinda, died in infancy. Their third child, Meriwether – the closest in age and friendship to Reuben – became the famous first half of the Lewis and Clark Expedition which explored the uncharted West before he met his tragic and mysterious death on the Natchez Trace in Tennessee. While Reuben’s life has been rightly overshadowed by his older brother Meriwether’s …

Ash Aerosol Particle Size Distribution, Composition, And Deposition Behavior While Co-Firing Coal And Steam-Exploded Biomass In A 1.5 Mwth Combustor, Rajarshi Roy, Brian Schooff, Xiaolong Li, Scott Montgomery, Jacob Tuttle, Jost O.L. Wendt, Kingsley Dickson, Brian Iverson, Andrew R. Fry

Faculty Publications

Five different blends of Utah bituminous coal and steam-exploded pine (100/0, 75/25, 50/50, 25/75, 0/100 by mass) were fired in a 1.5 MWth combustor. Primary objectives were to understand mineral matter behavior by analyzing aerosol size distribution, aerosol size-segregated composition, ash deposition mass, and ash composition. For particle size < 0.1 μm, pure coal had the lowest aerosol concentration and pure biomass showed the highest (higher nucleation of potassium salts), a trend which reversed for particles >0.1 μm. During pure biomass combustion, aerosol particles >15 μm contained higher mass fractions of potassium (+126%), calcium (+132%), and iron (+115%) and lower fractions of aluminum (−49%) and silicon (−29%) than pure coal. Ash deposition mass decreased with increasing biomass blends. …

Origami-Based Design Of Conceal-And-Reveal Systems, Bryce P. Defigueiredo, Kyler A. Tolman, Spencer P. Magleby, Nathan A. Pehrson, Erica Crampton, Larry L. Howell

Faculty Publications

This work introduces a type of motion termed “conceal-and-reveal” which is characterized by a state that protects a payload, a state that exposes the payload, and coupled motions between these two states. As techniques for thick, rigid origami-based engineering designs are being developed, origami is becoming increasingly more

attractive as inspiration for complex systems. This paper proposes a process for designing origami-based conceal- and-reveal systems, which can be generalized to design similar thick, rigid origami-based systems. The process

is demonstrated through the development of three conceal-and-reveal systems that present a luxury product to the consumer. The three designs also confirm …

Regional Stiffness Reduction Using Lamina Emergent Torsional Joints For Flexible Printed Circuit Board Design, Bryce P. Defigueiredo, Brian Dale Russell, Trent K. Zimmerman, Larry L. Howell

Faculty Publications

Flexible printed circuit boards (PCBs) make it possi- ble for engineers to design devices that use space efficiently

and can undergo changes in shape and configuration. How- ever, they also suffer from trade-offs due to non-ideal mate- rial properties. Here, a method is presented that allows en- gineers to introduce regions of flexibility in otherwise rigid

PCB substrates. This method employs geometric features to reduce local stiffness in the PCB, rather than reducing

the global stiffness by material selection. Analytical and fi- nite element models are presented to calculate the maximum

stresses caused by deflection. An example device is produced …

Kinematic/Static Model Of Complex Compliant Mechanisms With Serial-Parallel Substructures: A General Approach, Mingxiang Ling, Junyi Cao, Larry L. Howell

Faculty Publications

Kinematic and static analyses of compliant mechanisms are crucial at the early stage of design, and it can be difficult and laborsome for complex configurations with distributed compliance. In this paper, a general and concise kinematic/static modeling method of flexure-hinge-based compliant mechanisms with arbitrary serial-parallel substructures is presented to provide accurate and efficient solutions by combining the matrix displacement method with the transfer matrix method. The transition between the elemental stiffness matrix and the transfer matrix of the flexure hinge and the flexible beam is straightforward, enabling the condensation of a hybrid serial-parallel substructure into one equivalent element simple. Then, …

Origami-Inspired Sacrificial Joints For Folding Compliant Mechanisms, Todd G. Nelson, Alex Avila, Larry L. Howell, Just L. Herder, Davood Farhadi Machekposhtic

Faculty Publications

Folding is a manufacturing method which can create complex 3D geometries from flat materi- als and can be particularly useful in cost-sensitive or planar-limited fabrication applications.

This paper introduces compliant mechanisms that employ folding techniques from origami to evolve from a flat material to deployed state. We present origami-inspired sacrificial joints, joints which have mobility during assembly of the mechanism but are rigid in their final position, to create regions of high and low stiffness and the proper alignment of compliant flexures in folded mechanisms. To demonstrate the method we fold steel sheet to create some well-known and complex compliant …

A Pseudo-Static Model For Dynamic Analysis On Frequency Domain Of Distributed Compliant Mechanisms, Mingxiang Ling, Larry L. Howell, June Cao, Zhou Jiang

Faculty Publications

This paper presents a pseudo-static modeling methodology for dynamic analysis of distributed compliant mechanisms to provide accurate and efficient solutions. First, a dynamic stiffness matrix of the flexible beam is deduced, which has the same definition and a similar form as the traditional static compliance/stiffness matrix but is frequency-dependent. Second, the pseudo-static modeling procedure for the dynamic analysis is implemented in a statics-similar way. Then, all the kinematic, static and dynamic performances of compliant mechanisms can be analyzed based on the pseudo- static model. The superiority of the proposed method is that when it is used for the dynamic modeling …

Normalized Coordinate Equations And Energy Method For Predicting Natural Curved-Fold Configurations, Jacob Badger, Todd G. Nelson, Rober J. Lang, Denise M. Halverson, Larry L. Howell

Faculty Publications

Of the many valid configurations that a curved fold may assume, it is of particular interest to identify natural—or lowest energy—configurations that physical models will preferentially assume. We present normalized coordinate equations—equations that relate fold surface properties

to their edge of regression—to simplify curved-fold rela- tionships. An energy method based on these normalized

coordinate equations is developed to identify natural con- figurations of general curved folds. While it has been noted

that natural configurations have nearly planar creases for curved folds, we show that non-planar behavior near the crease ends substantially reduces the energy of a fold.

Remembering Sarah Duvall, Norm Krasne

Newsletter of the Jussi Björling Societies of the USA & UK

After suffering a catastrophic stroke last summer, one of our fellow JBSers, my partner Sarah Duvall, passed away on August 15th. Compared to most in our Society, she was a relative newcomer to opera and to Jussi’s heavenly tenor. As her exposure to the art form grew, she came to prefer more contemporary operatic works to the more traditional classics, but she recognized superior singing when she heard it. Portland (OR) Opera was our home base and over a decade we became more involved with the Company and made many friends among its supporters and staff. Sarah was a volunteer …

Bidú: Passion And Determination By Denis Allan Daniel, Tom Hines

Newsletter of the Jussi Björling Societies of the USA & UK

According to the author, this is the first biographical study in English of the world-renowned Brazilian soprano, Bidú Sayão, who had a storied career in opera during the l930s, 1940s, and1950s. Of considerable interest to members of the Jussi Björling Societies, this study emphasizes her collaboration with Jussi in major Metropolitan Opera productions...notably Gounod’s Roméo et Juliette (1947)and Puccini’s La bohème (especially the 1948 performance). Blessed with a haunting lyric soprano voice, she specialized in bel canto roles that took her to the major operatic houses of the world and left an indelible impression on critics and audiences alike. She …

Jussi Björling: We Remember (Jussi Björling En Minnesbok), Sue Flaster

Newsletter of the Jussi Björling Societies of the USA & UK

Short weeks after Jussi Björling’s death in September of 1960, Bertil Hagman launched himself on an ambitious project: to record reminiscences of the great tenor while those memories were still fresh. Hagman interviewed several dozen friends and colleagues who knew Jussi and had performed with him, and by the end of 1960 had published Jussi Björling en Minnesbok (JB A Memory Book).
