Behavioral Response of Rhyzopertha dominica, Lesser Grain Borer, to Wheat Volatiles

The lesser grain borer is a grain pest that eats and damages grain products such as rice, corn, wheat, and millet (Edde, 2012). The lesser grain borer has a tendency to to reproduce rapidly and explode into big infestations under optimal conditions, which become hard to control (Johnson, 2000). Controlling these infestations has been moderately successful with the use of pheromones, which attract the beetles (El-Azi, 2011). The purpose of this research is to pinpoint the lesser grain borer’s potential preference of different wheat volatiles it is given, and find the strongest response. The hypothesis is that certain samples that have higher moisture, a stronger odor, or an added pheromone that could elicit the strongest response to the volatiles than samples that do not have these conditions. The results obtained from this research indicate that our hypothesis is fairly correct, showing the aged, wet wheat with an added pheromone had the highest preference among all samples tested. The significance of this research should bring the gap closer between effectively controlling the lesser grain borer and grain safety, which will maximize the product, reduce the potential hazards to human health, and be the framework for other similar problems with grain pests around the worl

Pace/Place/Space/Tempo—The choreography of equity and expressions of Black Living

My skin is natural. My skin is political. My hair is natural. My hair is political. My speech is natural. My speech is political. There’s no such thing as apolitical. My current interdisciplinary practice in painting and performance focuses on how Black diasporic identities hold, create, and process subsistence narratives. For this research, I am asking the questions: What role does pace play in resistance strategies and how can it be communicated through tempo? How are unspoken histories conveyed through movement, silence, the glance of an eye, fat crackling in a cast iron, pushing play on a walkman, and seeds thrown in the garden? How can my practice ‘map’ these diasporic ways of knowing and amplify ongoing struggles for Black womxn living? As a study of embodied histories, my inquiry begins with a dialogue between the external and internal which I will describe through the lens of movement, informed by Black Feminist Theory, The Black Radical Tradition, and In The Shadow Of Slavery. I will conclude with how diasporic these ways of knowing are dynamically choreographed to create liberatory experiences within oppression through experimentalisms in pace, place, space, and tempo. we made ourselves small so we’d have room to move room to dance room to sing room to laugh room to scream room to think without their eyes watching so that we’d have room to breathe and more comfortably sit and move our wrists and our hips so that we would know in the marrow of our bones what freedom feels like

The Development Of Old-Growth Structural Characteristics In Second-Growth Forests Of The Cumberland Plateau, Kentucky, U.s.a.

Prior to Euro-American colonization beginning in the late 1700s and subsequent periods of land conversion and intensive resource extraction, most forest on the Cumberland Plateau in Kentucky would have existed in a state meeting one or more of the definitions of old-growth forest in use today. However, many recovering, mature forests currently exist that might be redeveloping old-growth structure and function. To assess the development of old-growth forest characteristics in second-growth forests, 70 - 90 year old (young) and 140 - 160 year old (old) hardwood forests in the Daniel Boone National Forest were examined for a suite of structural characteristics to discern patterns of structural and successional development. Old forest was distinguishable from young forest, having reached thresholds similar to old-growth for presence of large canopy trees, coarse woody debris volume and size distribution, multi-age distribution, age of oldest trees, and complex canopy structure. Both ages of forest met thresholds for total basal area and met some proposed thresholds for stem density. Neither age of forest met suggested minimum densities for old-growth for snags \u3e 30 cm DBH, though old forest had almost three times that of young forest, and nearly approached values reported for old-growth forest. Young and old forest also exhibited different patterns in oak and maple dynamics. Understory maples and overstory oaks recruited synchronously in young forest during the 1920s and 1930s, while recruitment of both species in old forest was temporally more broadly distributed

Nondestructive testing of concrete bridge decks using ground-penetrating radar and the chain drag method

This thesis presents the findings of two different nondestructive techniques that are used for bridge deck analysis: the chain drag method and ground penetrating radar (GPR). The chain drag testing was performed in the laboratory with 23 simulated concrete bridge deck specimens. The specimens contained varying internal conditions such as with/without steel reinforcement and with air and water filled cracks. The tests were to determine if the chains could uncover the different characteristics of each specimen, and to see if the varying sizes of the three chains had any influence on the outcome of the results.;The GPR testing was performed in the field on three highway bridge decks. The purpose of this testing was to determine if the GPR technique could accurately assess the depths to the different deck interfaces (overlay/concrete, 1st layer rebar, deck bottom, etc.), and to examine whether the radar software could find bridge deterioration

Evaluation for Intensive Home Community Based Services: A Program for At-Risk Youth and their Families

The purpose of this longitudinal evaluation study was to examine client perceptions of the Home Community Based Services Program (HCBS) located in two rural counties in Central Minnesota. It was hypothesized that adjudicated youth (ages 12-17), who have access to the HCBS Program may experience less out-of-home placements and less criminal re-offending. Data was collected utilizing two surveys, one at exit of services, and one six months after discharge of services. Findings indicated clients perceived the HCBS Program a positive experience introducing change in the family system. Less out-of-home placement was experienced for youth involved in the HCBS Program. The literature review formulated that a need exists for specialized intensive programs targeting high-risk youth. Previous research provided a construct supporting community based programs as intervention sites for high-risk youth and their families. Cost effectiveness gained relevance in conducting the literature search. The cost per residential placement for one youth is approximately $40,000 per year, (Social Services Census Report, 1995), HCBS Program\u27s cost$53,000 per year
