Exploring Stress Overshoot Phenomenon Upon Startup Deformation Of Entangled Linear Polymeric Liquids, Yangyang Wang, Shi-Qing Wang
Exploring Stress Overshoot Phenomenon Upon Startup Deformation Of Entangled Linear Polymeric Liquids, Yangyang Wang, Shi-Qing Wang
College of Polymer Science and Polymer Engineering
This work explores the picture associated with stress overshoot during sudden continual (i.e., startup) external deformation of entangled polymeric liquids and proposes a specific scaling form to depict the intermolecular interactions responsible for chain deformation. Following a previously proposed idea that the stress overshoot in startup deformation is a signature of yielding, we search for ingredients that should go into the description of the force imbalance at the yield point and show that the expression for the intermolecular locking force f(iml), derived from the characteristics associated with the yield point, can be tested against experiment. New rate-switching experiments support the …
Nature Of Steady Flow In Entangled Fluids Revealed By Superimposed Small Amplitude Oscillatory Shear, Pouyan E. Boukany, Shi-Qing Wang
Nature Of Steady Flow In Entangled Fluids Revealed By Superimposed Small Amplitude Oscillatory Shear, Pouyan E. Boukany, Shi-Qing Wang
College of Polymer Science and Polymer Engineering
We carry out a systematic investigation into steady-state shear behavior of six entangled solutions based on a superposition of continuous shear and small amplitude oscillatory shear (SAOS). During steady shear in the shear thinning regime, the superimposed SAOS frequency sweep measurements reveal characteristics of viscous liquids, e. g., terminal dynamics, on the experimental time scale of the reciprocal shear rate. The residual entanglement network retains the same level of elastic stiffness as the equilibrium system does. Consistent with the convective constraint release idea, chains in the network are forced to pass around each other as they must do so to …
Study Of Take-Up Velocity In Enhancing Tensile Properties Of Aligned Electrospun Nylon 6 Fibers, Johnny F. Najem
Study Of Take-Up Velocity In Enhancing Tensile Properties Of Aligned Electrospun Nylon 6 Fibers, Johnny F. Najem
Mechanical Engineering Faculty Research
The variation of both the tensile properties and thermal properties of aligned electrospun fibers with the take-up velocity (TUV) of disc collector has not been widely investigated due to the difficulty of handling aligned nanofibers and measuring low loads. In this thesis, 25% of nylon 6 was dissolved in formic acid and then electrospun into fibers and the fibers were aligned using a rotating disc collector. We evaluated the tensile and thermal properties, average fiber diameter, crystallinity, crystalline morphology, molecular and crystalline orientation of aligned electrospun nylon 6 nanofibers as a function of TUV based on a disc collector. It …

Masters Theses & Doctoral Dissertations
More and more organizations are evaluating the best route to mobilize their workers, whether field service personnel, sales representatives or on the move executives.
Amway is the largest multi-level marketing (MLM) organization in the world. In Amway, one is recruited as an "independent" distributor of Amway products by buying a couple of hundred dollars' worth of the products from the one who recruits you, known as your "up line." Every distributor in turn tries to recruit more distributors. Income is generated by sales of products by the distributor plus "bonuses" from sales of his or her recruits and their recruit-descendents. …

True catalases are tyrosine-liganded, usually tetrameric, hemoproteins with subunit sizes of ∼55-84 kDa. Recently characterized hemoproteins with a catalase-related structure, yet lacking in catalatic activity, include the 40-43 kDa allene oxide synthases of marine invertebrates and cyanobacteria. Herein, we describe the 1.8 Å X-ray crystal structure of a 33 kDa subunit hemoprotein from Mycobacterium avium ssp. paratuberculosis (annotated as MAP-2744c), that retains the core elements of the catalase fold and exhibits an organic peroxide-dependent peroxidase activity. MAP-2744c exhibits negligible catalatic activity, weak peroxidatic activity using hydrogen peroxide (20/s) and strong peroxidase activity (∼300/s) using organic hydroperoxides as co-substrate. Key amino …
How Do Animal Mitochondria Tolerate Water Stress?, Michael A. Menze, Steven C. Hand
How Do Animal Mitochondria Tolerate Water Stress?, Michael A. Menze, Steven C. Hand
Faculty Publications
The vast majority of animal species do not tolerate severe water stress, but the encysted embryo of the brine shrimp Artemia franciscana is an exceptionally useful organism to investigate physiological mechanisms for enduring extreme environmental insults. Any substantial reduction in cellular water poses a threat to survival. Nevertheless anhydrobiotic animals survive virtually complete loss of cellular water. The mechanisms that govern " life without water" (anhydrobiosis) are still not well understood. With certain exceptions, it seems that a recurring strategy for tolerating severe water loss involves the accumulation of both low molecular weight solutes (e.g., trehalose or other polyol) and …
Creation And Implementation Plan For A Sales Engineering Minor At California Polytechnic University, San Luis Obispo, Joshua M. Checkis
Creation And Implementation Plan For A Sales Engineering Minor At California Polytechnic University, San Luis Obispo, Joshua M. Checkis
Biomedical Engineering
The profession of Sales Engineering (S.E.) offers engineers a unique opportunity to fuse their technical background with communication and business skills in order to seek a rewarding alternative to the typical engineering career path. The shortfall of this niche industry is the lack of formal academic programs that seek to develop the skills necessary to prepare engineers for the field. At this time only two sales engineering minors exist in the nation, one at Iowa State University and the other at the University of Florida. The process for this senior project was to clearly identify the scope of a competitive …

Existing Biomass Infrastructure And Theoretical Potential Biomass Production In The U.S, Jeremy R. Porter, Frank M. Howell, Philip B. Mason, Troy C. Blanchard
Faculty Publications
The recent and projected status of energy production and consumption in the U.S., resulting in substantial dependencies upon foreign oil, has continued to provide pressure on domestic energy security. All told, bio-energy systems, and biomass crop production in particular, will be important elements of national security, economic vitality, and public policy. Using biomass crop estimates based upon models developed at the Oak Ridge National Laboratory, we identify potential biomass crop production zones within the contiguous 48 states of the United States using spatially centered analytic methods. The Midwest and the South regions of the United States are, by far, the …
The Role Of Is Project Critical Success Factors: A Revelatory Case, Cecil Eng Huang Chua, Wee-Kiat Lim
The Role Of Is Project Critical Success Factors: A Revelatory Case, Cecil Eng Huang Chua, Wee-Kiat Lim
CCX Research
Research in Critical Success Factors (CSFs) of Enterprise Systems (ES) projects has identified numerous practitioner governance mechanisms for ensuring project success. However, such research has not developed a theory of why certain critical success factors encourage project success. Our research develops such theory on a case study where even though the levels of several critical success factors were weak, the project nevertheless succeeded. Specifically, the logistics ES project succeeded even though there was (1) only marginal top management support, (2) low key user commitment, and (3) change management, training and other critical aspects of user management and communication were not …

Empirical Mode Decomposition Operator For Dewowing Gpr Data, Bradley M. Battista, Adrian Addison, Camelia C. Knapp
Faculty Publications
Signal processing tools available to ground penetrating radar data used for shallow subsurface imaging and hydrogeophysical parameter estimation are significantly handled using the same tools available to seismic reflection data. Overall, the same tools produce interpretable images from both data types, but particular noise (wow noise) in electromagnetic data must be removed before stable and accurate quantitative results can be produced. Wow noise is an inherent, nonlinear electromagnetic interference and a significant component of GPR data. Further, the nonlinear and non-stationary nature of wow noise provides a strong argument for preprocessing radar traces with time-domain operators. Time-domain operators designed for …

Heme Reversibly Damps Period2 Rhythms In Mouse Suprachiasmatic Nucleus Explants, C. J. Guenthner, David Bickar, Mary E. Harrington
Psychology: Faculty Publications
The hypothalamic suprachiasmatic nucleus (SCN), which in mammals serves as the master circadian pacemaker by synchronizing autonomous clocks in peripheral tissues, is composed of coupled single-cell oscillators that are driven by interlocking positive/negative transcriptional/translational feedback loops. Several studies have suggested that heme, a common prosthetic group that is synthesized and degraded in a circadian manner in the SCN, may modulate the function of several feedback loop components, including the REV-ERB nuclear receptors and PERIOD2 (PER2). We found that ferric heme (hemin, 3-100 μM) dose-dependently and reversibly damped luminescence rhythms in SCN explants from mice expressing a PER2::LUCIFERASE (PER2::LUC) fusion protein. …
A Bandwidth Aware Modification To The Dsr Routing Protocol For Wireless Mesh Networks, Mustafa Ramadhan, Mark Davis
A Bandwidth Aware Modification To The Dsr Routing Protocol For Wireless Mesh Networks, Mustafa Ramadhan, Mark Davis
Conference papers
This work proposes a bandwidth aware cross-layer modification to the DSR routing protocol. We include the Access Efficiency Factor (AEF) parameter in addition to the hop-count in the routing discovery mechanism. AEF is a measure to the local availability of bandwidth at a node. Employing the AEF as a metric in the routing discovery mechanism attempts to avoid routing through a congested area in the network. In this modification, we impose a limit on the hop-count in order to control the delay time in the network. The path selection procedure operates by finding a path with the highest minimum AEF …

The 2009 Personal Firewall Robustness Evaluation, Ken Pydayya, Peter Hannay, Patryk Szewczyk
Australian Information Security Management Conference
The evolution of the internet as a platform for commerce, banking, general information and personal communications has resulted in a situation where many individuals who may not have previously required internet access now require this connectivity as part of their everyday lives. In addition to this the widespread adoption of mobile broadband has lead to an increasing number of individuals having public facing IP addresses with no firewall appliances present. This situation has dramatically increased reliance on personal firewalls as the first and often last defence against intruders (human and malware alike). The evaluation performed demonstrates the capabilities of current …

Electronic-Supply Chain Information Security: A Framework For Information, Alizera Bolhari
Australian Information Security Management Conference
Over the last few years, the materials and distribution management has developed into a broader strategic approach known as electronic supply chain management by means of information technology. This paper attempts to visibly describe supply chain management information security concepts which are necessary for managers to know about. So, the depth of information presented in this paper is calibrated for managers, not technical security employees or agents. Global supply chains are exposed to diverse types of risks that rise along with increasing globalization. Electronic supply chains will be more vulnerable from information security (IS) aspect among other types of supply …

Exploring The Relationship Between Organizational Culture And Information Security Culture, Joo S. Lim, Shanton Chang, Sean Maynard, Atif Ahmad
Australian Information Security Management Conference
Managing Information Security is becoming more challenging in today’s business because people are both a cause of information security incidents as well as a key part of the protection from them. As the impact of organizational culture (OC) on employees is significant, many researchers have called for the creation of information security culture (ISC) in organizations to influence the actions and behaviour of employees towards better organizational information security. Although researchers have called for the creation of ISC to be embedded in organizations, nonetheless, literature suggests that little past research examining the relationship between the nature of OC and ISC. …

Pozzolanic Activity Of Rice Husk Ash: Comparison Of Various Electrical Methods, S Wansom, S Janjaturaphan, S Sinthupinyo
Journal of Metals, Materials and Minerals
The great abundance of rice husk ash (RHA) as low-cost agricultural waste in Thailand makes it the most suitable material for cement-based applications. However, the use of RHA as a supplementary cementitious material (SCM) is not yet widespread in Thailand due to the poor pozzolanic activity of most agricultural RHA. Most RHA is incinerated at too high temperatures (usually in excess of 1000ºC) or under uncontrolled conditions as biomass fuel. This reduces the amount of amorphous SiO2 and hence worsens the pozzolanic activity of the resulting RHA. To enhance the use of RHA as an SCM in Thailand, a proper …
