description: This Ph.D. thesis describes novel hardware/software architectures for adaptive low-power embedded multimedia systems. Novel techniques for run-time adaptive energy management are proposed, such that both HW & SW adapt together to react to the unpredictable scenarios. A complete power-aware H.264 video encoder was developed. Comparison with state-of-the-art demonstrates significant energy savings while meeting the performance constraint and keeping the video quality degradation unnoticeable.

The KK-Monopole/NS5-Brane in Doubled Geometry
Creators: name: Jensen, Steuard

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The Kaluza-Klein monopole has been recognized as a string background with significant non-geometric features: it must appear "localized" to winding strings to match the NS5-brane's localization on the T-dual circle. In this work, we explicitly construct this T-dual system in the doubled geometry formalism, which proves to successfully describe the duality despite a broken isometry on one side of the duality pair. We further suggest an extension of the doubled formalism to the gauged linear sigma models describing this system (both bosonic and supersymmetric) and show that previous calculations of worldsheet instanton effects are best understood in this doubled form.

Examining Inclusion: Social Entrepreneurship for People with Disabilities in Taiwan
Creators: name: Chih-Chieh Hsu
Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: In Taiwan, social entrepreneurship is a trend regarded as an innovative mode of assisting people with disabilities to solve their life challenges and further reduce their consumption of social welfare resources. This perspective focuses on the role of people with disabilities as service users in social enterprises but ignores their roles as service providers in social enterprises. Especially when I reviewed studies on social entrepreneurship and disabilities in Chinese literature, the studies on social entrepreneurs with disabilities were almost nonexistent. By integrating literature on Disability Studies, Human Rights-based Approach, and social entrepreneurship theory, this dissertation conducted in-depth interviews with fifteen social entrepreneurs with disabilities and seven key stakeholders to explore disability entrepreneurial experience within a socio-political context of Taiwan, including their social impacts, startup reasons, and startup barriers. This research finding highlights the social contributions of fifteen disabled social entrepreneurs and further discovers the entrepreneurial resources that can assist them in strengthening their social impacts. The research result will bridge the research gap on disability and entrepreneurship and can be used as a reference for the Taiwanese government to improve current disability employment policy.

description: We have measured velocity dispersions for a sample of 36 galaxies with J < 21.2 or Mr < -20.6 mag in MS1054-03, a massive cluster of galaxies at z = 0.83. Our data are of uniformly high quality down to our selection limit, our 16-hour exposures typically yielding errors of only δ(dispersion)~10% for L* and fainter galaxies. By combining our measurements with data from the literature, we have 53 cluster galaxies with measured dispersions, and HST/ACS-derived sizes, colors and surface brightnesses. This sample is complete for the typical L* galaxy at z~1, unlike most previous z~1 cluster samples which are complete only for the massive cluster members (>1e11 M_sun). We find no evidence for a change in the tilt of the fundamental plane (FP). Nor do we find evidence for evolution in the slope of the color-dispersion relation and M/L_B-dispersion relations; measuring evolution at a fixed dispersion should minimize the impact of size evolution found in other work. The M/L_B at fixed dispersion evolves by Δlog10 M/L_B=-0.50 +/- 0.03 between z=0.83 and z=0.02 or d(log10 M/L_B)=-0.60 +/- 0.04 dz, and we find Δ(U-V)_z=-0.24 +/- 0.02 mag at fixed dispersion in the rest-frame, matching the expected evolution in M/L_B within 2.25 standard deviations. The implied formation redshift from both the color and M/L_B evolution is z*=2.0 +/- 0.2 +/- 0.3 (sys), during the epoch in which the cosmic star-formation activity peaked, with the systematic uncertainty showing the dependence of z* on the assumptions we make about the stellar populations. The lack of evolution in either the tilt of the FP or in the M/L- and color-dispersion relations imply that the formation epoch depends weakly on mass, ranging from z*=2.3 +1.3 -0.3 at 300 km/s to z*=1.7 +0.3 -0.2 at 160 km/s and implies that the IMF similarly varies slowly with galaxy mass.

Publisher: name: Springer International Publishing
Year: 2021

description: Vertical profiles of the wind speed, turbulence components, and the temperature in the lower regions of the atmospheric boundary layer can be determined by performing active acoustic and radioacoustic sounding with ground-based devices. This chapter introduces two types of instruments — sound detection and ranging (sodar) devices and radioacoustic sounding systems (RASS) — that can be used to carry out such measurements. While sodars can provide quantitative vertical wind and turbulence profiles and qualitative mixed-layer height and inversion height data, RASS can provide that as well as quantitative temperature profiles. Both types of instruments have a typical height range of several hundreds of meters, and their vertical resolution is on the order of 20m.

description: The nonlocal spin injection in lateral spin valves is highly expected to be an effective method to generate a pure spin current for potential spintronic application. However, the spin valve voltage, which decides the magnitude of the spin current flowing into an additional ferromagnetic wire, is typically of the order of 1 μV. Here we show that lateral spin valves with low resistive NiFe/MgO/Ag junctions enable the efficient spin injection with high applied current density, which leads to the spin valve voltage increased hundredfold. Hanle effect measurements demonstrate a long-distance collective 2-pi spin precession along a 6 μm long Ag wire. These results suggest a route to faster and manipulable spin transport for the development of pure spin current based memory, logic and sensing devices.

Role of the first coordination shell in determining the equilibrium structure and dynamics of simple liquids

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: The traditional view that the physical properties of a simple liquid are determined primarily by its repulsive forces was recently challenged by Berthier and Tarjus, who showed that in some cases ignoring the attractions leads to large errors in the dynamics [L. Berthier and G. Tarjus, Phys. Rev. Lett. 103, 170601 (2009); J. Chem. Phys. 134, 214503 (2011)]. We present simulations of the standard Lennard-Jones liquid at several condensed-fluid state points, including a fairly low density state and a very high density state, as well as simulations of the Kob-Andersen binary Lennard-Jones mixture at several temperatures. By varying the range of the forces, results for the thermodynamics, dynamics, and structure show that the determining factor for getting the correct statics and dynamics is not whether or not the attractive forces {\it per se} are included in the simulations. What matters is whether or not interactions are included from all particles within the first coordination shell (FCS) - the attractive forces can thus be ignored, but only at extremely high densities. The recognition of the importance of a local shell in condensed fluids goes back to van der Waals; our results confirm this idea and thereby the basic picture of the old hole- and cell theories for simple condensed fluids.
Homeless and street-involved youth access to primary health care services : what helps and what gets in the way?
Creators: name: Pitcher, Claire
Publisher: name: University of British Columbia
Year: 2017

description: Introduction: On any given night, thousands of Canadian youth face homelessness in either absolute (living on the street) or relative (couch surfing) terms. Youth experiencing homelessness report disproportionately high rates of illness and unique influences on their access to health care as compared to their stably housed peers. Method: I conducted a mixed methods study to examine influences on homeless youth access to health care. First, I interviewed eight homeless youth about their experiences accessing health care. Next, I conducted a focused analysis of the 2014 Homeless and Street-Involved Youth Survey which was conducted in 13 communities across British Columbia with 671 youth. Finally, I facilitated a solutions-focused dialogue with a panel of 4 health care and allied service providers who work with homeless youth. Data analysis was informed by procedures consistent with interpretive description as the methodological orientation. Results: I identified three themes from the interviews: youth experiencing homelessness feel powerless when interacting with health care providers; health care systems exist as ‘rule-based’ bureaucracies; and homeless youth are in ‘survival mode’ when it comes to their health. At the same time, findings from the focused survey analysis suggest that the effect of individual factors (e.g., age) on access to health care is confounded by more systemic factors, such as discrimination and access to stable shelter, which are themselves associated with foregone care. The expert panel supported these findings and further suggested that hurtful interactions may damage not only a youth’s relationship with the health care system but also their overall trust in others. The panel also suggested that before health care providers can ‘do health stuff’ with a youth they need to have had several opportunities to cross paths and connect in more informal ways first. Discussion and Implications: A multi-pronged intersectoral approach founded on communication, collaboration and coordination of care is needed to facilitate access to health care for homeless youth. Additionally, specialized training is needed for people who work with these youth. More work is also needed across health care and social service sectors to empower youth in relation to their health and seeking health care.

description: Fucoidan of Sargassum echinocarpum was extracted using the UAE method. This method produced a fucoidan extract with a yield of 2.82-3.93% and antioxidant activity of 44.57-98.77 ppm at different temperatures and extraction times. The total sulphate, fucose, phenolic, protein, and uronic acid contents were 5.50-6.24%, 17.22-63.22%, 14.66-78.20 mgGAE/g, 0-14.42 mg/g, and 191.43-353.76 mg/g, respectively. Furthermore, extraction treatment with UAE also affected the topology and morphology of the fucoidan extract. The analysis results showed the presence of monosaccharides such as galactose 1.37%, mannose 0.642%, and xylose 2.86%, while glucose and rhamnose were not detected. The extract also had the same absorption band as the fucose and fucoidan standard (F. vesiculosus) as well as a similar basic skeletal structure. Based on the experimental results, the fucoidan extract had excellent antioxidant properties.
Direct detection of WIMPs : Implications of a self-consistent truncated isothermal model of the Milky Way's dark matter halo

description: Direct detection of Weakly Interacting Massive Particle (WIMP) candidates of Dark Matter (DM) is studied within the context of a self-consistent truncated isothermal model of the finite-size dark halo of the Galaxy based on the "King model" of the phase space distribution function of collisionless DM particles. Our halo model takes into account the modifications of the phase-space structure of the halo due to the gravitational influence of the observed visible matter in a self-consistent manner. The parameters of the halo model are determined by a fit to a recently determined circular rotation curve of the Galaxy that extends up to $\sim$ 60 kpc. Unlike in the Standard Halo Model (SHM) customarily used in the analysis of the results of WIMP direct detection experiments, the velocity distribution of the WIMPs in our model is non-Maxwellian with a cut-off at a maximum velocity that is self-consistently determined by the model itself. For our halo model that provides the best fit to the rotation curve data, the 90% C.L. upper limit on the WIMP-nucleon spin-independent cross section from the recent results of the CDMS-II experiment, for example, is $\sim 5.3\times10^{-8}\pb$ at a WIMP mass of $\sim$ 71 GeV. We also find, using the original 2-bin annual modulation amplitude data of the DAMA experiment, that there exists a range of small WIMP masses, typically $\sim$ 2 -- 16 GeV, within which DAMA collaboration's claimed annual modulation signal purportedly due to WIMPs is compatible with the null results of other experiments. These results strengthen the possibility of low-mass ($\lsim 10\gev$) WIMPs as a candidate for dark matter as indicated by several earlier studies performed within the context of the SHM. A more rigorous analysis using DAMA bins over smaller intervals should be able to better constrain the "DAMA regions" in the WIMP parameter space within the context of our model.

description: In quantum optics and its applications, there is an urgent demand for photon-number resolving detectors. Recently, there appeared multi-pixel detectors (MPPC) that are able to distinguish between 1,2,..10 photons. At the same time, strong coupling between different pixels (cross-talk) hinders their photon-number resolution. In this work, we suggest a method for `filtering out' the cross-talk effect in the measurement of intensity correlation functions.

description: In the last decade, Pd(0) nanoparticles have attracted increasing attention due to their outstanding utility as nanocatalysts in a wide variety of key chemical reactions. Remarkably, it has now been well-recognized that the encapsulation of Pd(0) nanoparticles as catalysts in various porous systems can protect the catalyst from deactivation, facilitate its separation and significantly increase its reusability. Encapsulated Pd(0) nanoparticles have also had great impact on the catalytic process in terms of reactivity and selectivity, through imposing confinement effects. In this review, we have tried to underscore the potential advantages associated with various organic, inorganic and hybrid porous systems, such as dendrimers, silica mesoporous systems, MOFs and zeolites, for Pd(0) encapsulation between 2005-2016 and disclose the role of confinement effects on the promotion of catalytic activity of the Pd(0) encapsulated species, which have been used as catalysts in some important organic transformations such as C-C coupling reactions, hydrogenation and oxidation reactions. The advantages and merits provided and observed using the encapsulated Pd(0) nanoparticles are compared with those of the corresponding conventional species. These qualities, particularly in terms of Pd leaching, reusability and activity, are systematically discussed.
Alkene Amidooxysulfonylation: Development & Application to the Common Daphniphyllum Alkaloid Core

description: The electrophile addition (AdE) reaction of alkenes to form 1,2-bifunctional products is among the more widely studied processes in the field of organic chemistry, reflecting its value as a means to rapidly install chemical complexity. Despite long-standing interest in this type of reaction, the oxyamination, or addition of nitrogen and oxygen-based groups, of alkenes remains a challenging transformation. This thesis describes the development of a synthetic method for the amidooxysulfonylation of alkenes, employing hypervalent iodine reagents. A discussion of the application of this method to the synthesis of bicyclic alkaloid natural product targets follows. Chapter 1 opens with a review of the chemistry of O-alkyl hydroxamates and the nitrenium ions, or equivalent species, accessed through the N-oxidation of these substrates. Details of the development of a versatile method for the amidooxysulfonylation of unsaturated O-alkyl hydroxamates employing hypervalent iodine reagents are then discussed. In Chapters 2 and 3, the application of this methodology to the preparation of the functionalized core structures of two alkaloid families, namely those belonging to the Daphniphyllum and Delphinium groups, is described. More specifically, the A/B/C-ring system of (-)-himalensine A and the A/E/F-ring system of (+)-methyllycaconitine are prepared. In the final chapter, we described the development and implementation of a synthetic strategy for the selective diastereoselective preparation of 4-substituted 1,2-trans-cyclohexyldiamines, and the application of this method to the synthesis of a functional CyDTPA-based metal chelator for use in PET imaging.

On Eling-Oz formula for the holographic bulk viscosity

description: Recently Eling and Oz [1] proposed a simple formula for the bulk viscosity of holographic plasma. They argued that the formula is valid in the high temperature (near-conformal) regime, but is expected to break down at low temperatures. We point out that the formula is in perfect agreement with the previous computations of the bulk viscosity of the cascading plasma [2,3], as well as with the previous computations of the bulk viscosity of N=2^* plasma [4,5]. In the latter case it correctly reproduces the critical behaviour of the bulk viscosity in the vicinity of the critical point with the vanishing speed of sound.

Acoustic Frequency Analysis Investigating Frequency Differences in Acute Chest Syndrome

Publisher: name: University of Illinois at Chicago

Subjects: Uncategorized

description: Acute chest syndrome (ACS) is the leading cause of death among people with sickle cell disease, which affects the hemoglobin in red blood cells causing them to sickle in shape. ACS is clinically defined and diagnosed by the presence of a new pulmonary infiltrate on chest imaging with accompanying fever and respiratory symptoms like hypoxia, tachypnea, and shortness of breath. However, the characteristic chest x-ray (CXR) findings necessary for a clinical diagnosis of ACS can be at times difficult to detect, as is determining which patient needs a CXR. This makes early detection hard, but it is critical for limiting the severity of ACS and subsequent fatalities. The other diagnostic method currently used is computed tomography (CT), but these are more expensive and expose patients to more radiation. This research project looks to apply percussion and auscultation techniques that can provide an immediate diagnosis of acute pulmonary conditions by using a standardized input called the Tabla and electronic auscultation for post frequency analysis. Sickle cell patients having acute chest syndrome, vaso-occlusive crisis (VOC), and regular clinic visits were recorded from and analyzed using MATLAB. Those subjects with a clear clinical diagnosis of ACS were analyzed separately to compute the frequency spectrum of the recordings. These spectrums were averaged to give the ACS subject pool average and the same was done for the healthy subject group. This analysis revealed that there was an average of 10-14 dB decrease in sound intensity in the ACS subject group compared to the healthy group. Because of acute chest syndrome’s complex clinical presentation and pathogenesis, a thorough retrospective analysis of each patient’s EMR was performed to identify confounding variables that might remove them from the subject pool. This review along with frequency analysis revealed a new classification label for subjects who had complicated VOC, meaning some sort of pulmonary infiltrate was present. A random under-sampling boosted tree classification model was performed identifying with 89% accuracy the positive ACS observations and healthy observations. Future work will continue to gather more ACS data to continue to train and test more classification algorithms.

description: In this work, we predict two charged charmonium-like structures close to the $D^\ast\bar{D}$ and $D^\ast\bar{D}^\ast$ thresholds, where the Initial Single Pion Emission mechanism is introduced in the hidden-charm dipion decays of higher charmonia $ψ(4040)$, $ψ(4160)$, $ψ(4415)$ and charmonium-like state Y(4260). We suggest BESIII to search for these structures in the $J/ψπ^+$, $ψ(2S)π^+$ and $h_b(1P)π^+$ invariant mass spectra of the $ψ(4040)$ decays into $J/ψπ^+π^-$, $ψ(2S)π^+π^-$ and $h_b(1P)π^+π^-$. In addition, the experimental search for these structures in the $J/ψπ^+$, $ψ(2S)π^+$ and $h_c(1P)π^+$ invariant mass spectra of the $ψ(4260)$ hidden-charm dipion decays will be accessible at Belle and BaBar.

Engineering high performance electrodes for energy storage devices from low-cost, sustainable and naturally abundant biomaterials
Creators: name: Watson, Timothy
Publisher: name: University of British Columbia
Year: 2017

description: With the increased global push towards sustainable energy utilization, the need for advanced energy storage technologies has become increasingly important as countries seek to integrate rapidly advancing renewable energy technologies like wind and solar. At the same time, the burgeoning electric vehicle and wearable electronics industries are fuelling demand for lower-cost energy storage devices with high energy capacities and longer cycle lives. Currently, despite huge leaps in performance of Li-Ion batteries in recent years, the technology is approaching its predicted limits and new solutions will be needed to keep up with the demand of current and future electrical devices. At a time where scientific applications of nanomaterials and nanofabrication is on the rise, there exists an opportunity to take advantage of our increased understanding of nanotechnology to significantly improve existing energy storage devices and to unlock the potential of next-generation energy storage technologies. In this work, binder-free and porous graphitic nanofibre electrodes produced from low-cost and sustainable softwood kraft lignin are devised and proposed as a platform for the development of high-performance energy storage devices. Motivated by difficulties facing some key energy storage technologies, scalable electrospinning of lignin and polyethylene oxide (PEO) precursor materials, followed by a hydrothermal treatment and carbonization in an inert atmosphere yields free-standing interconnected nanofibre electrodes with tunable porosity, high conductivity and superior electrochemical performance. Electrical impedance spectroscopy measurements of the optimized porous nanofibre electrodes demonstrate a conductivity reaching 18.39 S cm-¹, while Brunauer-Emmett-Teller specific surface area measurements yield a specific surface area as high as 1258.41 m² g-¹. Supercapacitor devices revealed highly symmetric cyclic voltammetry results which demonstrated a gravimetric capacitance approaching 112 F g-¹ at a voltage scan rate of 5 mV s-¹. Galvanostatic charge/discharge experiments show reversible supercapacitor behaviour, a high capacity even at elevated voltage scan rates up to 200 mV s-¹ and exhibit excellent cyclic stability, retaining 91% of their initial capacity after 6000 cycles. This work demonstrates the use of sustainable and abundant softwood Kraft lignin as source for porosity-tunable electrodes with high capacitance and stability as a demonstration of nature sourced and high performance electronic devices.

description: Pink pepper (Schinus terebinthifolius Raddi) is a native species native from Central and South America that produces an essential oil (EOpp) with promising applications. This work aimed to investigate the chemical composition and cytotoxic activity of EOpp extracted from unripe (U-EOpp) and ripe (R-EOpp) pink pepper fruits. U-EOpp and R-EOpp were extracted using the hydrodistillation technique and analysed using NMR and GC-MS. U-EOpp and R-EOpp cytotoxic activity was assessed using HL-60 (acute promyelocytic leukemia) and SK-MEL-28 (malignant melanoma) cell lines by MTT assay. Results showed that α-pinene (29.16%), dl-Limonene (20.65%), and ρ-cymene (15.86%) were U-EOpp major components. In addition, l-phellandrene (38.91%), Sylvestrene (23.02%), and α-pinene (21.62%) were R-EOpp major components. U-EOpp showed cytotoxic activity at 37.5 and 18.7 µg/mL for SK-MEL-28 and HL-60, respectively. R-EOpp showed cytotoxic activity for HL-60 at 100 µg/mL. Therefore, EOpp may represent a remarkable source of active natural compounds used in traditional Brazilian medicine.

description: We propose a class of inflation models in which the coefficient of the inflaton kinetic term rapidly changes with energy scale. This may occur especially if the inflaton moves over a long distance during inflation as in the case of large-scale inflation. The peculiar behavior of the kinetic term opens up a new way to construct an inflation model. As a concrete example we construct a linear inflation model in supergravity. It is straightforward to build a chaotic inflation model with a fractional power along the same line. Interestingly, the potential takes a different form after inflation because of the running kinetic term.

In situ TEM to Study Iron Crystallization Mechanism in Ferritin
Creators: name: Narayanan, Surya
Publisher: name: University of Illinois at Chicago

Subjects: Uncategorized

description: Ferritin is an iron storage protein that regulates iron, stores excess iron, and prevents free radical formation in the human body. The iron in stored as iron oxides inside the protein through the process of biomineralization. Despite several years of research, the iron biomineralization mechanism in ferritin is sparsely known. Further, with evidences of brain iron accumulation in neurological conditions, it is important to understand the iron regulation mechanism in ferritin. Transmission electron microscopy has revolutionized our current understanding of nanostructures and chemistry of ferritin. While it is possible to obtain high spatial resolution with traditional electron microscopy, the application was limited to material sciences for a long time. The need to dry and condition the sample before imaging, restricted its application towards certain specific biological applications. While the evolution of Cryo-electron microscopy tapped the potential to study the structure of hydrated proteins such as ferritin, the applications were still limited to the structural aspects. With recent advancements in microfluidics and chip design, it has become possible to study the dynamics of biomolecules. Although this technology provided several opportunities to study ferritins in liquid phase, it also raises question about the resolution that the microfluidic technology can offer. On the other hand, advancements in graphene liquid cell-transmission electron microscopy (GLC-TEM) enabled atomic resolution imaging of ferritin without compromising the liquid environment of the protein. xxvii The focus of this dissertation will be, firstly to introduce ferritins and its structure, morphology, chemistry and biology as discussed in Chapter 1. Further, the focus will be on the TEM sample preparation techniques utilized to study the ferritin’s structure as discussed in Chapter 2. Different techniques, its advantages and benefits are discussed in this chapter. Further, this chapter also emphasizes the utilization of GLC-TEM to study ferritins in hydrated state. Chapter 2 is further extended as the characterization of GLC-TEM and its significance in imaging biological materials such as ferritin is emphasized in Chapter 3. By utilizing GLC-TEM, the morphology, structural, and chemical characteristics of iron oxides in human ferritins were compared as described in Chapter 4. The significance of this work is to emphasize the role of naturally distinct ratios of amino acid subunits in different organ ferritins in producing iron oxides of different structural and chemical composition. Further, GLC-TEM technique was utilized to study in situ biomineralization in ferritin in realtime as described in Chapter 5. The results obtained through the novel in situ GLC-TEM technique can result in new frontiers in science to study biological structures and better understand human health which is discussed in Chapter 6.
Measurement of the production cross section for W-bosons in association with jets in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

description: This Letter reports on a first measurement of the inclusive W+jets cross section in proton-proton collisions at a centre-of-mass energy of 7 TeV at the LHC, with the ATLAS detector. Cross sections, in both the electron and muon decay modes of the W boson, are presented as a function of jet multiplicity and of the transverse momentum of the leading and next-to-leading jets in the event. Measurements are also presented of the ratio of cross sections sigma(W+ \ge n) / sigma(W+ \ge n-1) for inclusive jet multiplicities n=1-4. The results, based on an integrated luminosity of 1.3 pb-1, have been corrected for all known detector effects and are quoted in a limited and well-defined range of jet and lepton kinematics. The measured cross sections are compared to particle-level predictions based on perturbative QCD. Next-to-leading order calculations, studied here for n \le 2, are found in good agreement with the data. Leading-order multiparton event generators, normalized to the NNLO total cross section, describe the data well for all measured jet multiplicities.

description: One new cyclopeptide, cyclo-(L-Trp-L-Phe-L-Phe) (1), one new 2-pyridone derivative, fusarone A (3), and one new natural indole derivative, ethyl 3-indoleacetate (4), along with six known compounds were isolated from the endophytic fungus Fusarium proliferatum T2-10. The planar structures of three new compounds were identified by spectral methods including 1D and 2D NMR techniques, and the absolute configuration of compound 1 was elucidated by Marfey-MS method. In addition, all compounds were evaluated for their cytotoxic and antibacterial activities in vitro. Compound 2 showed remarkable cytotoxic activities against two human hepatoma cell lines SMMC7721 and HepG2 with IC50 values of 5.89 ± 0.74 and 6.16 ± 0.52 μM, and showed moderate antibacterial activities against Staphylococcus aureus and Enterococcus faecalis with MIC values of 7.81 and 15.62 μg/mL, respectively.

description: Foodborne illness is a growing concern world-wide, and Campylobacter in particular has been reported to cause approximately 145,000 foodborne illness cases every year in Canada. A recent annual report from the Canadian Integrated Program for Antimicrobial Resistance Surveillance reveals an increasing trend of antibiotic-resistant Campylobacter isolated from poultry sources across Canada. The large number of foodborne illnesses and emergence of the resistant strains of Campylobacter pose a serious threat in the agri-food industry. Hence, there is increasing urgency to find alternatives to conventional antimicrobials to reduce the prevalence of Campylobacter in the food supply chain while reducing the likelihood of resistance. Combining antimicrobials is a potential intervention strategy to reduce the growth of pathogens by expanding the spectrum of antimicrobial activity. In this study, carvacrol and zinc oxide nanoparticles (ZnO NPs) were investigated in regards to their synergistic antimicrobial effect against C. jejuni. The combination of these two agents for treatment is based upon current evidence of their individual antimicrobial activity. The objectives of this thesis project were to (1) determine the synergistic antimicrobial effect of carvacrol and ZnO NPs against C. jejuni, (2) investigate the macromolecular fingerprints and gene expression profile of C. jejuni after the combinational treatment, and (3) explain the potential mechanism of the synergistic antimicrobial effect. In this work, a macrobroth dilution method was used to test the antimicrobial effect of the compounds against C. jejuni. The macromolecular fingerprints of C. jejuni cells treated with carvacrol and ZnO NPs were investigated using confocal micro-Raman spectroscopy, whereas Real-Time Quantitative Polymerase Chain Reaction (RT-qPCR) was employed to study the variation in bacterial gene expression after the antimicrobial treatment. The synergistic antimicrobial effect of carvacrol and ZnO NPs against C. jejuni was clearly demonstrated using the time-kill curve. The macromolecular fingerprints and gene expression profile revealed the role of carvacrol in the synergistic antimicrobial effect against C. jejuni. The results of this study provide fundamental knowledge about bacterial stress in response to the synergistic antimicrobial effects. This antimicrobial combination may be utilized as an intervention strategy to reduce the prevalence of C. jejuni in agri-foods.
