Abstract:
... To explore how older adults in rural communities navigate food insecurity, ten focus groups were held in Indiana, USA with 65 discussants. Recordings underwent inductive qualitative data analysis. Driving and transport remain a barrier to rural food access. Living alone is another contributor to food insecurity, while older adults’ social networks are protective. Congregate meal sites are critical ...

Abstract:
... Traditional hyperspectral image (HSI) classification methods mainly include machine learning and convolutional neural network. However, they extremely depend on the large training samples. To obtain high accuracy on limited training samples, we propose a novel end-to-end spectral-spatial multi-scale network (SSMSN) for HSI classification. The SSMSN uses the multi-scale spectral module and the mult ...

Abstract:
... The Operational Land Imager (OLI) onboard the Landsat 8 satellite has a panchromatic band (503–676 nm) that has been used to compute a virtual spectral band known as “orange contra-band” (590–635 nm). The major application of the orange contra-band is the monitoring of cyanobacteria which is usually quantified by the measurement of the concentration of phycocyanin (PC) which has an absorption peak ...

Abstract:
... Quantitatively assessing attenuation and dispersion of elastic‐wave velocities in partially saturated reservoir is difficult because of its sensitivity to fluid distribution. We conducted experiments on homogeneous Indiana limestone samples, partially saturated by two methods: drying and imbibition which lead to different fluid distribution for a given saturation. Forced oscillations (from 0.004 t ...
Indiana, etc ; corn; ethanol; farms; market power; models; prices; spatial variation; transportation; Show all 9 Subjects
Abstract:
... We estimate the degree of spatial differentiation–primarily driven by transportation costs–among downstream firms that buy corn from upstream farmers and examine whether such differentiation softens competition enabling buyers to exert market power (defined as the ability to pay a price for corn that is below its marginal value product net of processing cost). We estimate a structural model of spa ...

Abstract:
... An understanding of how CO₂ foam flows through a reservoir rock is useful for many subsurface applications, including enhanced oil recovery and CO₂ storage. There are economic and environmental benefits in identifying surfactants that exhibit good foaming behavior with CO₂ at both low concentrations and high foam qualities. Core flood experiments have been carried out to investigate the behavior o ...

Abstract:
... Understanding retention of chemicals onto the rock surface with varying wettabilities allows for better understanding of behavior and performance of the chemicals for applications in oil-bearing rocks. This work studied dynamic retention properties of the low-cost encapsulated petroleum sulfonate nanofluid–Nano-Surfactant (NS)–to the Indiana limestone outcrop surfaces at various wettabilities and ...

Abstract:
... Position-specific (PS) isotopes of propane have been proposed as a potential geochemical tool to decipher various geological processes (e.g., thermal cracking, biodegradation, H exchange) in natural reservoirs. The limited studies have been conducted on the PS isotopes of propane from the pyrolysis gases from marine shales, and natural gases sourced from lacustrine and marine kerogens, but little ...

Abstract:
... Hyperspectral datasets are widely used in many applications of remote sensing in the fields of agriculture, forestry, weather, urban planning, water study, biodiversity and surface changes. Our focus is agriculture with different perspectives such as classifications of crops, identification of different crop growth stages, fallow land, etc. However, the major challenge in working with hyperspectra ...

Abstract:
... Understanding the transactions that occur between humans and their environments requires research focused on phenomena that explain behavioral patterns, particularly values that serve as guiding principles in life. Mounting evidence has suggested that pro-environmental behavior is motivated by the long-term goal of living a meaningful life, as reflected by Aristotle's concept of eudaimonia. Howeve ...

Abstract:
... Channelization has changed the form and dynamics of rivers on a global scale. In the midwestern United States, widespread straightening of meandering headwater streams has been undertaken for the purpose of improving land drainage. Few studies have examined in detail how meandering streams respond to straightening, especially over timescales of nearly a century following straightening. This study ...

Abstract:
... Midwest oak savannas contain some of the highest plant diversity in the United States and are among the rarest terrestrial ecosystems globally. Consequently, understanding diversity patterns within these ecosystems is important for setting management and restoration goals. This study aimed to understand the role of canopy cover and heterogeneity in canopy cover in influencing plant alpha and beta ...

Abstract:
... Climate change presents serious risks to human communities around the world. To ensure rapid, widespread and equitable adaptation to these risks, government policy must be enacted to support community-wide adaptation. Public support for adaptation policy will be key to its passage. To date, few studies have focused on what factors motivate public support for adaptation policy, especially at the su ...

Abstract:
... Electric roadways (ERs) represent a new paradigm for electrified transportation that is enabled by the emerging technology of dynamic (in-motion) wireless power transfer to electric vehicles (EVs). This kind of ubiquitous charging capability alleviates range anxiety, and can thus stimulate the adoption of EVs. However, large-scale deployment of ERs is challenging due to its high capital cost and r ...
... Environmentally sustainable food consumption is one component of addressing climate change. Previous research has largely approached sustainable food consumption by investigating individual behaviors, without a broader conceptualization of what motivates food consumers to act sustainably. Using a representative sample of Indiana consumers, we explore sustainability across a range of food behaviors ...

Abstract:
... In enhanced oil recovery, surfactants are injected to recover the residual oil by reducing the oil/water interfacial tension or by altering the wettability of the rock. Viscoelastic surfactants are a special class of surfactants that can also control mobility due to their viscoelastic nature, in addition to lowering interfacial tension. However, detailed studies of wettability alteration by viscoe ...
... Serum samples from 24 subjects (6 mother–daughter and 6 mother–son dyads) in a rural community (Columbus Junction, Iowa) and 24 subjects (6 mother–daughter and 6 mother–son dyads) in an urban community (East Chicago, Indiana) were analyzed for 74 sulfated metabolites of polychlorinated biphenyls (PCBs). We detected significantly higher mean concentrations of total assessed PCB sulfates in the urba ...
... Senecavirus A (SVA) infection in pigs causes vesicular disease and results in a short viremia and transient shedding of the virus, mainly in oral fluids and feces. Here we describe the consistent prolonged shedding of SVA in the semen of 2 boars, and persistence of SVA within the tonsils and testes of 3 adult boars. Two SVA-infected boars that were identified on a Minnesota sow farm in 2017 shed S ...

Abstract:
... CONTEXT: Maximum clique analysis (MCA) can approximate landscape carrying capacity (Nₖ) for populations of territorial wildlife. However, MCA has not been widely adopted for wildlife applications, mainly due to computational constraints and software wildlife biologists may find difficult to use. Moreover, MCA does not incorporate uncertainty into estimates of Nₖ. OBJECTIVES: We extended MCA by app ...
