Comparative Evaluation Of Cotesia Flavipes And C. Sesamiae (Hymenoptera: Braconidae) For The Management Of Chilo Partellus (Lepidoptera: Pyralidae) In Kenya, M. N. Sallam, W. A. Overholt, E. Kairu

All Peer-Reviewed Publications

Cotesia flavipes Cameron, a gregarious larval endoparasitoid native to the Indo-Australian region, was imported from Pakistan and released in Kenya in 1993 for management of the exotic stemborer, Chilo partellus (Swinhoe). Recent reports confirmed the successful establishment of the parasitoid in three locations in Kenya and in northern Tanzania. Functional response studies on this parasitoid and an indigenous congener, Cotesia sesamiae (Cameron), indicated that C. flavipes had a higher searching ability and attacked more larvae when Chilo partellus was the host. When a native stemborer, Sesamia calamistis Hampson, was the host, there was no significant difference between numbers attacked by …

A Model-Based Approach For Compression Of Fingerprint Images, Fikret Erçal, M. Gokmen, Ilker Ersoy

Computer Science Faculty Research & Creative Works

We propose a new fingerprint image compression scheme based on the hybrid model of an image. Our scheme uses the essential steps of a typical automated fingerprint identification system (AFIS) such as enhancement, binarization and thinning to encode fingerprint images. The decoding process is based on reconstructing a hybrid surface by using the gray values on ridges and valleys. In this compression scheme, the ridge skeleton is coded efficiently by using differential chain codes. The valley skeleton is derived from the ridge skeleton and the gray values along the ridge and valley skeletons are encoded using the discrete cosine transform. …

The Brine Shrimp Artemia Franciscana In Closed Microalgal-Based Microcosms (Biospheres), Rachel L. Yung, Mark A. Gouthro, James R. Rosowski

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The purpose of this study was to examine the effects of three experimental variables on the stability and fecundity of a brine-shrimp community in a closed, micro algal-based microcosm. Xenic microalgal cultures and brine shrimp (Artemia franciscana Kellogg) in 300-cc acrylic spheres (referred to as biospheres or microcosms) were subjected to three experimental variables: (1) the culture volume (150 ml or 250 ml), (2) presence or absence of daily culture mixing (sphere rotation), and (3) a microcosm atmosphere that was either closed or open to the surrounding atmosphere. Each sphere started with 200 brine shrimp cysts and the microalga …

Electron Liquid Beyond The Random Phase Approximation, Mehmet Tomak, Ceyhun Bulutay

Turkish Journal of Physics

A deeper understanding of low-dimensional and small-scale electronic systems requires an accurate characterization of the many-electron effects. Based on the electron liquid (EL) model, these many-body effects in the three-dimensional (3D) and two-dimensional (2D) electronic systems are dealt going beyond the random phase approximation within the zero-temperature framework. The dielectric formulation of the many-body problem is recapitulated and the longitudinal dielectric function of the EL is obtained using the self-consistent local-field correction scheme, known as STLS, under a general spin-valley degeneracy. Extensive explicit expressions are provided for the use of other researchers. The performance of this formalism is compared in …

Magnetic Excitations In Random Anisotropic Magnets, İbrahim Avgin

Turkish Journal of Physics

A study is made for the magnetic excitations and their Anderson localization properties for a Heisenberg ferromagnet with random anisotropic fields. The system is assumed to be in a strong applied field so that complete spin alignment is established. The magnetic excitations, i.e., the harmonic spin waves, are computed using coherent-field-anisotropy approximation (a version of coherent potential approximation of the electronic problem). The spin wave shift and damping are calculated using the computed coherent field which is a complex function of energy approximating the random medium as a mean field level. The localizaton of the excitations are calculated by adopting …

Dam Nation: A Geographic Census Of American Dams And Their Large-Scale Hydrologic Impacts, William L. Graf

Faculty Publications

Newly available data indicate that darns fragment the fluvial system of the continental United States and that their impact on river discharge is several times greater than impacts deemed likely as a result of global climate change. The 75,000 dams in the continental United States are capable of storing a volume of water almost equaling one year's mean runoff, but there is considerable geographic variation in potential surface water impacts. In some western mountain and plains regions, darns can store more than 3 year's runoff, while in the Northeast and Northwest, storage is as little as 25% of the annual …

Creating A New University Through Object Oriented Enterprise Modeling: A Study Of Communications Knowledge Management & Distributed Cognition, Armando A. Arias Jr., Beryl L. Bellman

SSGS Faculty Publications and Presentations

Enterprise based object oriented (OO) and Unified Modeling Language (UML) modeling makes it possible to build the needed visual environments to organize people, technologies and activities (Arias, 1999d). In our modeling approach, the focus is on "things and relationships between things" described in commonly used terms. The modeling software bridges the so-called "semantic gap" between the people and the computer language (Booch, Rumbaugh & Jacobson, 1999). An object can be a product, a process, a person, a team, a company, an application or the inter-relationship between other objects. Objects can be pictured on the screen as maps formed by personalized …

Synthesis Of Benzoxazoles Containing Allyl Crosslinking Sites Via Claisen Rearrangements, Leslie K. Hutson

Browse all Theses and Dissertations

The reaction of diethyl 2,5-dihydroxyterephthalate with allyl bromide/K2CO3 in DMF followed by hydrolysis provided 2,5-di(allyloxy)terephthalic acid. The conversion of 2,5-di (allyloxy)terephthalic acid to 1,4-di(2-benzoxazolyl)-2,5-di(allyloxy)benzene in PPSE was unsuccessful. However, the reaction of 1,4-di(2-benzoxazolyl)-2,5- dihydroxybenzene with allyl bromide/K2CO3 provided 1,4-di(2-benzoxazolyl)-2,5- di(allyloxy)benzene. DSC analysis indicated that 1,4-di(2-benzoxazolyl)-2,5- di(allyloxy)benzene undergoes a Claisen rearrangement to the corresponding diallyl product. The synthesis of 2-allyloxy-1,4-di(2-benzoxazolyl)benzene was carried out using 2-hydroxy-1,4-di(2-benzoxazolyl)benzene as starting material. DSC analysis was inconclusive with respect to a Claisen rearrangement. The reaction of 2-allyloxybenzoic acid with 2,2-bis(3-amino-4-hydroxyphenyl)-1,1,1,3,3,3-hexafluoropropane in PPSE was unsuccessful but the reaction of 2,2-bis(2-(2-hydroxyphenyl)-5-benzoxazolyl)-1,1,1,3,3,3-hexafluoropropane with allyl bromide/K2CO3 in DMF provided 2,2-bis(2-(2- …

Sic And Si3N4 Recession Due To Sio2 Scale Volatility Under Combustor Conditions, James L. Smialek, R. Craig Robinson, Elizabeth J. Opila, Dennis S. Fox, Nathan S. Jacobson

United States National Aeronautics and Space Administration: Publications

SiC and Si3N4 materials were tested under various turbine engine combustion environments, chosen to represent either conventional fuel-lean or fuel-rich mixtures proposed for high speed aircraft. Representative CVD, sintered, and composite materials were evaluated in both furnace and high pressure burner rig exposure. While protective SiO₂ scales form in all cases, evidence is presented to support paralinear growth kinetics, i.e. parabolic growth moderated simultaneously by linear volatilization. The volatility rate is dependent on temperature, moisture content, system pressure, and gas velocity. The burner tests were used to map SiO₂ volatility (and SiC recession) over a range of temperature, …
