Show moreNorovirus is one of the leading causes for foodborne illness. Transmission of virus from surface to food has been known to cause a number of outbreaks. Studies of norovirus have been conducted using Murine Norovirus to simulate the behaviors. Pulsed light (PL) is a promising surface decontamination technology, which has the potential to be applied in a food service setting. PL uses intense pulses of short duration and a broad spectrum to accomplish microbial inactivation. This study evaluates the effect of PL on MNV-1, artificially inoculated onto various food contact surfaces including 304 stainless steel, glazed tile, polypropylene, and ultra-high molecular weight (UHMW) polyethylene. The virus was allowed to inoculate on the coupons for 20mins and treated with PL in a Xenon Steripulse XL-3000TM pulsed light treatment system for up to 60 s, at a distance of 8.3 cm 10.8 cm or 13.3cm from the central axis of the lamp. An infrared (IR) camera was used to record surface temperatures, in 1-s increments. After PL treatments, remaining viruses were recovered from surfaces and quantified by plaque assay. At a distance of 10.8cm, MNV-1 was reduced by 2.22-, 2.27- 2.75- and 3.12-log, after 20s treatment on inoculated stainless steel, glazed tile, UHMW polyethylene and polypropylene, respectively. After 50s treatment, MNV-1 was reduced by 4.86- and 5.93- log on glazed tile and stainless steel surface respectively. The surface temperature on tile and stainless steel increased at the rate of 1.08±0.20 and 1.28±0.32°C /s respectively. A relatively short treatment using pulsed light is sufficient to inactivate MNV-1 on the surface of materials commonly used in food preparation. The results suggest that the technology has the potential to reduce surface viral contamination in a food preparation setting.

Show moreStroke survivors often experience long-term upper extremity impairment. This can greatly impair activities of daily living. The eXtension Glove (X-Glove) is a soft robotic device to aid hand therapy. It uses cables serving as external extensor tendons to assist digit extension and control digit flexion. Load cells are located on each motor to detect the force value of fingers. This paper provides a way to add a biofeedback function on the X-Glove and update the microprocessor to a PIC32MX795. So the X-Glove can establish a wireless communication transmit data with terminals, like PC. In order to display the biofeedback, a graphic user-interface is also developed so that therapists can optimize the therapy for each individual patient in real time.

Show moreLarge-scale spatially distributed systems provide a unique and difficult control challenge because of their nonlinearity, spatialdistribution and generally high order. The control structure for these systems tend to be both discrete and distributed as well and contain discrete and continuous elements. A layered control structure interfaced with complex arrays of sensors and actuators provides a flexible supervision and control system that can deal with local and global challenges. An adaptive agent-based control structure is presented whereby local control objectives may be changed in order to achieve the global control objective. Information is shared through a global knowledge environment that promotes the distribution of ideas through reinforcement. The performance of the agent-based control approach is illustrated in a case study where the interaction front between two competing autocatalytic species is moved from one spatial configuration to another. The multi-agent control system is able to effectively explore the parameter space of the network and intelligently manipulate the network flow rates such that the desired spatial distribution of species is achieved.

Show moreSalmonella enterica has been frequently linked to the major foodborne disease outbreaks. The molecular mechanisms underlying this pathogen survival on the fresh fruit surface remain largely unexplored. In this study, the environmental factors that affect the survival of Salmonella strains on the surface of selected fruits were studied. Grape tomatoes (or cantaloupe peels) were inoculated in three separate trials with 1 mL Salmonella enterica serotypes Enteritidis or Typhimurium (approximately 1010-11 CFU/mL). Storage of grape tomatoes at 4 ℃ resulted in significant decrease in populations of S. Enteritidis; this trend was observed at both of the tested relative humidity with the D-value as 7.25±1.05 d and 7.28±2.34 d, respectively. At different temperatures, relative humidity only had marginal effects on the bacterial survival on the surface of grape tomato and cantaloupe. In addition, S. Typhimurium apparently survived better than S. Enteritidis on the surface of grape tomato. Furthermore, a transposonmutagenesis library with random transposon insertion mutants of S. Enteritidis and high-throughput sequencing analysis showed that the expression of genes rcsB and nlpD were hypothesized to be associated with the survival of S. Enteritidis on grape tomatoes. Inframe deletions of the two genes in S. Enteritidis were constructed by lambda red recombinase system and respective complementation mutants were also obtained for identification of the contribution of the two genes to the bacterial survival on the surface of grape tomato. Thus, this study provided microbiological and molecular microbiological basis to probe the roles of putative genes in Salmonella enterica survival on the surface of fresh fruits.

Show moreThe goal of IPRO 320 is to create an online professional network for school teachers at the kindergarten through twelfth grade level to allow for the sharing of ideas, lesson plans and other professionally relevant information. This is a continuing project which saw limited success in the previous semester in that a functioning web site was constructed based on surveys of public school teachers but it saw very little use. This semester, the planned approach is to build on the research generated last semester by performing additional market research with teachers. Following that, IPRO 320 will rework much of the previous web site by refining some of the features, adding additional ones as the research indicates and improving the website in general, both functionally and aesthetically.

Show moreThe flight muscle of Manduca sexta has some interesting properties. It is synchronous, like mammalian skeletal and cardiac striated muscle, but it is structurally similar to the more widely studied asynchronous insect flight muscles of Drosophila and Lethocerus. One of the main goals of the thesis is to generate a useful skinned preparation for mechanical studies in vitro. A number of different skinning protocols were tried and evaluated for preservation of structural integrity by using light and X-ray diffraction. In all muscles studied to date, isometric force is a function of the [Ca2+] of the bathing solution and also a function of the sarcomere length whereby more force is generated at a longer sarcomere length than at a shorter for the same [Ca2+]. This phenomenon is termed “length dependent activation” (LDA). To date no real studies on the force-pCa relationship has been done on Manduca sexta flight muscle. This force-pCa analysis would give us some insight into the length dependent activation (LDA) in this novel insect flight muscle system. The present studies were undertaken to characterize and analyze the force-pCa relationships in Manduca sexta. Conditions were found that allowed skinning muscles while maintaining good structural order. We found that both DLMs dorsal and ventral show length-dependent activation at longer SL. Our study also shows that ventral muscles are more cooperative than the dorsal muscles which may be related to their different functions in vivo.

Show moreThis article demonstrates the use of a diary technique in a construction setting. The advantage of a diary study over other methods for capturing subjective experience is its ability to capture the thoughts, decisions, actions, and emotions of individuals in situ – while they are working in their natural setting – at multiple points in time during an individual’s workweek. Hence, the diary method is uniquely designed to answer questions about group-level trends as well as individual behavior. The specific goal of the study reported in this article was to derive an understanding of the types of fast decisions and actions that are made following a workflow disruption and how the disruption impacts the worker’s state of mind. The analyses revealed that there was a group-level positive correlation between experiencing a disruption and initiating a fast improvised decision and action. However, some workers tended to improvise frequently when disrupted while others did not. The analyses also revealed that the workers’ emotions fluctuated throughout the week, and two emotions – determined and interested – tended to decline following a disruption. But, some of the workers also experienced increases in their negative emotions while others did not, suggesting that not all workers react in the same way to disruptions. Consequently, the diary technique provides a novel way to identify the impact of disruptive events on worker decision-making and performance.

Show moreStochastic differential equations (SDEs) driven by non-Gaussian L´evy noises have attracted much attention recently [1, 29]. In [12], the authors studied a scalar SDE driven by a non-Gaussian L´evy motion, and numerically investigate mean exit time and escape probability for arbitrary noise intensity in one dimensional case. In the present thesis, we utilize a different strategy to explore a numerical method for the problem in two dimensional cases. To be specific, we assume the solution u(x) is radially symmetric with respect to the origin, and then represent the equation using radial coordinate, reducing the problem into one dimensional case. Then main difficulty is that, in the integral term, appears a Gauss Hypergeometric function and the unknown function u(r), which makes the error estimates complicated. We exploit some properties of Gauss Hypergeometric function, and finally make out a way for estimating the error [19]. Up to now we are only able to deal with this problem with 0 < α ≤ 1, since our numerical scheme does not converge when 1 < α < 2. Then we compare our numerical solutions with the analytical ones which are given in [3], and they coincide very well.

Show moreThrough analyzing data from posts and about users, we describe how one particular Facebook group helps immigrants to the U.S. use social media to build a local community. As a preliminary study in intercultural communication through social media, we analyze one case, the Asian American Chicago Network (AACN) Facebook group, and uncover common topics users discuss and relationships between user tenure and various indicators of leadership and interaction. Our small finalized results from this preliminary project suggest that members of AACN likely use it (1) to build a professional network in the U.S.A., and (2) to reinforce and affirm their Asian culture and identities.

Show moreThe olfactory system is an important chemosensory system. Our identification of odorants is occurred through binding of odorant molecules with olfactory receptors in the olfactory epithelium. In zebrafish, there are four classes of olfactory receptors: trace amine-associated receptor (TAAR), odorant receptor (OR), vomeronasal type 1-like receptor (V1R-like) and vomeronasal type 2-like receptor (V2R-like). In this study, I amplified four olfactory receptors taar1a, or1016, ora5 and olfcc1, which are respectively belong to the four olfactory receptor classes, from cDNA of the zebrafish olfactory epithelium and cloned genes into a mammalian expression vector pCI. The gene sequences of these receptors were not identical as the sequences obtained from GenBank database. The possible reasons for the inconsistency of gene sequence are discussed. I further tranfected these four cloned olfactory receptors in a mammalian cell line Hana3A. Expression of all four olfactory receptors in Hana3A cells was confirmed by immunocytochemistry. In summary, these four olfactory receptors taar1a, or1016, ora5 and olfcc1 were successfully cloned into the pCI vector and can be expressed on cell membrane surface of Hana3A cells.

Show moreIt is well known that the exponential growth in popularity of wireless devices has created a demand for radio spectrum that cannot be met with current regulatory policies. Despite the difficulty in procuring access to new spectrum resources, many empirical studies have indicated that the majority of spectrum is in-fact unused in the temporal, spatial and/or spectral domains, representing an untapped wealth that must be exploited. Dynamic Spectrum Access (DSA) is a promising technology which aims to improve the efficiency of future radios and alleviate the issue of spectrum under-utilization. This dissertation utilizes the data from the IIT Spectrum Observatory to develop models of channel activity on the Land Mobile Radio (LMR) band (used for critical communication by organizations such as public safety) and shows how such models can be applied to improve the performance of DSA. We demonstrate that LMR traffic may possess multi-timescale behavior – such as clustering and dispersion over different time periods – and propose a novel statistical model to account for these observations based on a multiple emission hidden Markov model. We then used this model to design a collision constrained channel selection algorithm that can permit the re-use of licensed spectrum while minimizing interference with incumbent users. The findings in this work are primarily developed for public safety, however the techniques developed are general enough to be applied to other types of traffic possessing similar characteristics. The proposed model, in particular, is well suited for further analytic work and simulations studies in this area.

Show moreDuchenne muscular dystrophy, DMD, is a severe X-linked recessive disease that kills boys in their second or third decade of life. A related condition Becker Muscular Dystrophy, BMD, is very heterogeneous with clinical severity ranging from nearly as bad as DMD, to nearly benign. Both of these are caused by defects in the dystrophin gene, which encodes a 427 kDa cytoskeletal protein, dystrophin, which can provide a mechanical link between the cytoskeleton and the muscle membrane and stables muscle tissue. In general, DMD results from defects that eliminate all dystrophin expression, whereas BMD patients carry mutated products: modified and malfunctioned dystrophin proteins. Since DMD is invariably fatal, monogenic, has a high incidence (1:3500 male births) and afflicts a charismatic patient profile, it has been an attractive target for gene therapy. However, the huge size of the dystrophin gene (2.4 Mbp) and more importantly its processed mRNA (14.2 kb) poses a problem for viral gene therapy which is limited to payloads of about 8 kb. This has prompted efforts to reduce the size of the dystrophin protein while still maintaining functionality. A major inspiration for such efforts was the identification of a very unusual, very large deletion serendipitously found in an extremely mild BMD case. The patient identified with this defect was ambulatory at 65 year of ages. This edit removes more than half the central rod region, from exon 17 to 48, Δe17-48, and, fortunately, the size of this BMD type edit protein is available for viral vector loading. In this project, edited dystrophin with central rod region deletion (D2:22 Δe17-48) and other two related edits, D2:22 Δe17-47 (exon 48 is added in D2:22 Δe17-48) and D2:22 Δe17-49 (exon 49 is deleted from D2:22 Δe17-48), were studied. According to these results, D2:22 Δe17-47 demonstrated the best biophysical and biochemical properties, but D2:22 Δe17-48 displayed higher to protease sensitivity, and D2:22 Δe17-49 had the worst thermal stability. This work will help us to understand the factors that result in benign large scale edits, and facilitate the development of effective viral gene therapy vectors.

Show moreHigh temperature, short time pasteurization was used to evaluate a computer-based system for controlling the pasteurization process, acquiring data, and monitoring records. Software was used for the control of hot water temperature, flow rate through the centrifugal timing pump, and diversion of under-processed product. Three types of control strategies were conducted: single loop, cascade, and multivariable. The single loop control strategy showed the most rapid responses to temperature changes, but the temperature response curve was slowest to return to its set point. The cascade control strategy showed slower recoveries to temperature changes, but the temperature response curve was smoother. The multivariable control strategy responded slightly faster than the cascade control strategy, and the temperature response curve was slightly smoother than the cascade control strategy. The multivariable control strategy was able to control the flow diversion valve by the use of a lethality controller. The data acquisition system, used to monitor the data obtained from the high temperature, short-time pasteurization system, was within +/- 0.1 degrees C of the temperature recorded by the safety thermal limit recorder. Reliability was determined by examining the changes in the position of the flow diversion valve to identify process deviations and by comparing the changes to the event marker on circular charts. The data acquisition system was an effective alternative for monitoring the completeness of data.
