Investigation Of Femtosecond Laser-Assisted Micromachining Of Lithium Niobate, A. Malshe, D. Deshpande, E. Stach, Kamlakar Rajurkar, Dennis R. Alexander

Department of Electrical and Computer Engineering: Faculty Publications

Lithium Niobate has a potential for applications in electronics and communication industries due to its unique electro-optical, piezoelectric and nonlinear properties. Femtosecond laser machining offers the best alternative to machine the mechanically fragile and optically delicate lithium niobate crystal. This paper reports a study of the effect of femtosecond laser machining on the surface integrity of lithium niobate. The transmission electron microscopy reveals a 100nm thin amorphous region and a void. The chemical analysis shows a loss of lithium and oxygen from the surface and sub-surface. Optical illumination facilitates the selective readout of the written spots of 2 microns size.

Grain sorghum (Sorghum bicolor) wax is composed mainly of aldehydes, alcohols, and acids. Aldehydes, comprising about one-half of the wax, are readily converted to acids in presence of air. In this study, whole sorghum wax and an aldehyde fraction from sorghum wax were subjected to oxidative conditions. Changes in the major components and thermal transition temperatures were determined using HPLC and differential scanning calorimeter (DSC), respectively. The aldehyde fraction was oxidized markedly to acids over 4 months in storage at room temperature. Acid content, in the fraction, was initially 5–7% and increased to 42–51% after 135 days in …


Controlled Release Systems For Dna Delivery, Angela K. Pannier, Lonnie D Shea Jan 2004

Controlled Release Systems For Dna Delivery, Angela K. Pannier, Lonnie D Shea

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Adapting controlled release technologies to the delivery of DNA has the potential to overcome extracellular barriers that limit gene therapy. Controlled release systems can enhance gene delivery and increase the extent and duration of transgene expression relative to more traditional delivery methods (e.g., injection). These systems typically deliver vectors locally, which can avoid distribution to distant tissues, decrease toxicity to nontarget cells, and reduce the immune response to the vector. Delivery vehicles for controlled release are fabricated from natural and synthetic polymers, which function either by releasing the vector into the local tissue environment or by maintaining the vector at …

Predicting Tractor Fuel Consumption, Robert D. Grisso, Michael F. Kocher, David H. Vaughan

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Reports from the Nebraska Tractor Test Laboratory (NTTL) show improved fuel efficiency during the past 20 years. A 4.8% decrease in average annual specific volumetric fuel consumption for the data used in the ASAE Standards was shown. Using fuel consumption and power data from the NTTL reports, new equations for fuel consumption were established that predict fuel consumption for diesel engines during full and partial loads and under conditions when engine speeds are reduced from full throttle.

Department of Biochemistry: Faculty Publications

The human hyaluronan receptor for endocytosis (hHARE) mediates the endocytic clearance of hyaluronan (HA) and chondroitin sulfate from lymph fluid and blood. Two hHARE isoforms (190 and 315 kDa) are present in sinusoidal endothelial cells of liver, spleen, and lymph nodes (Zhou, B., McGary, C. T., Weigel, J. A., Saxena, A., and Weigel, P. H. (2003) Glycobiology 13, 339–349). Here we report the specificity and function of the 190-kDa HARE, expressed without the larger isoform, in Flp-In 293 cell lines (190hHARE cells). Like the native protein, recombinant hHARE contains ~25 kDa of N-linked oligosaccharides, binds HA in a ligand blot …

Weeds [From Encyclopedia Of The Great Plains], Svata M. Louda

Svata M. Louda Publications

According to the U.S. Department of Agriculture, countless hours and millions of dollars are spent each year to control weeds, and millions more--hours and dollars--are lost in yield reductions. However, what exactly is a weed? And what makes a plant a weed? Many people are surprised to learn that a weed is technically "a plant out of place." So one person's weed can be someone else's salad green, pharmaceutical, transgenic crop, or wildflower! What are the characteristics of plants that often grow out of place? One characteristic is a tendency to reach high numbers rapidly and to replace or slow …


Metallic Single-Walled Silicon Nanotubes, Jaeil Bai, Xiao Cheng Zeng, Hideki Tanaka, J. Y. Zeng Jan 2004

Metallic Single-Walled Silicon Nanotubes, Jaeil Bai, Xiao Cheng Zeng, Hideki Tanaka, J. Y. Zeng

Xiao Cheng Zeng Publications

Atomistic computer-simulation evidences are presented for the
possible existence of one-dimensional silicon nanostructures: the
square, pentagonal, and hexagonal single-walled silicon nanotubes
(SWSNTs). The local geometric structure of the SWSNTs
differs from the local tetrahedral structure of cubic diamond
silicon, although the coordination number of atoms of the SWSNTs
is still fourfold. Ab initio calculations show that the SWSNTs
are locally stable in vacuum and have zero band gap, suggesting
that the SWSNTs are possibly metals rather than wide-gap
semiconductors.

The Ecology Of Interorganizational Information Sharing, Jane Fedorowicz, Janis L. Gogan, Amy W. Ray Jan 2004

The Ecology Of Interorganizational Information Sharing, Jane Fedorowicz, Janis L. Gogan, Amy W. Ray

Journal of International Technology and Information Management

Increasingly, companies use interorganizational information systems to support business process partnerships, such as automatic replenishment systems and other supply chain initiatives, invoicing and payments, and insurance claims processing. Inter-firm networking in turn can increase the visibility of information generated and used by business partners. These business partners may experience intended and unintended impacts from the changes in the partnering relationship, in effect altering the ecology of the organization. Yet IT researchers rarely study an organization’s ecology, focusing instead on impacts upon internal processes. Our goal in this paper is to propose a definition of interorganizational information ecology, to provide IT …

A Conceptual Framework For E-Branding Strategies In The Non-Profit Sector, Horst Treiblmaier, Irene Pollach, Arne Floh Jan 2004

A Conceptual Framework For E-Branding Strategies In The Non-Profit Sector, Horst Treiblmaier, Irene Pollach, Arne Floh

Journal of International Technology and Information Management

E-branding provides non-profit organizations (NPOs) with new opportunities to communicate their missions, which is of paramount importance in a market segment that competes for donations and voluntary labor. Since successful e-branding is determined by both internal and external communication strategies, we developed a framework which explains the interdependency of these two factors in NPOs. Our findings are based on qualitative interview data and a website analysis of eleven Austrian NPOs. The NPOs' internal and external e-communication strategies are categorized into three successive levels each and combined in a two-dimensional grid, which shows how NPOs integrate their communication strategies.

Building Relationships That Last: Integrating Public Relations Into Web Design, Richard V. Mccarthy, Jay E. Aronson, Robert Petrausch Jan 2004

Building Relationships That Last: Integrating Public Relations Into Web Design, Richard V. Mccarthy, Jay E. Aronson, Robert Petrausch

Journal of International Technology and Information Management

This paper explores the relationship between web site design, public relations strategy, and a consumer’s intention to return to a web site. This relationship is defined through a model that explores the influence of information satisfaction, particularly when the web site design is congruent with the consumer’s expectations. The public relations dimension extends the consumer web site design model by interjecting a long-term focus on relationship building that organizations will need to make electronic commerce a viable investment in information technology resources. This is significant because it recognizes the importance of developing loyalty and trust online.


Deciding On The Appropriateness Of B2b Reverse Auction Technology Adoption: An Ahp Approach Combined With Integer Programming, Tobias Schoenherr Jan 2004

Deciding On The Appropriateness Of B2b Reverse Auction Technology Adoption: An Ahp Approach Combined With Integer Programming, Tobias Schoenherr

Journal of International Technology and Information Management

Although Business-to-Business online reverse auctions have emerged as a promising purchasing tool, no research has been found that provides a model to assess the reverse auction decision in a systematic way. This paper fills this gap by presenting an integrated approach, utilizing Analytic Hierarchy Process techniques and an Integer Programming Formulation, to decide whether Reverse Auction Technology (RAT) adoption is cost-effective and appropriate. The model developed is a practical decision support tool that allows for the consideration of both qualitative and quantitative decision factors, and for the adoption of multiple modes of RATs, which are contrasted to traditional purchasing.
