description: This study examines the relationship of English Canadian historical feature films to Canadian cinema, historical subjects, and the formation of Canadian national identity. The thesis analyses key Canadian historical films from 1970 to 2010 that stand out from Canadian cinema’s typically art-house fare, and includes original interviews with Canadian film professionals and a comparison of contrasting models in Quebec and the United States. This study concludes with an argument for this subgenre’s marginality in Canada, which is rooted in the relationship of Canadians to their own history, a lack of “mythic nationalism” in Canadians’ understanding of their identity, budget limitations, a reliance on state subsidies, and a general lack of interest in Canadian cinema. English Canadian historical cinema is anti-heroic, does not accept a single meta-narrative of identity, and is distinctly multicultural in its content, which contributes to the creation of a unique identity that reflects contemporary Canadian values.

description: In this talk it is reported on an analysis of the form factors for the transitions from a photon to one of the pseudoscalar mesons pi0, eta, eta', etac within the modified perturbative approach in which quark transverse degrees of freedom are retained. The report is focused on the discussion of the surprising features the new BaBar data exhibit, namely the sharp rise of the pi-gamma form factor with the photon virtuality and the strong breaking of flavor symmetry in the sector of pseudoscalar mesons.

description: A new ultra-low background high-purity germanium (HPGe) detector has been installed at the Kamioka underground experimental site. The background count rate in the energy range from 40 keV to 2700 keV is about 25% lower than that of the first HPGe detector installed in 2016, which has the same detector specification and similar shielding geometry. This paper describes the shielding configuration, including the cleaning of the material surface, the comparison of calibration data and simulation, the time variation of the background spectra, the sample measurement procedure, and some results of the radioactivity in the selected samples.

description: We present a far-ultraviolet (FUV) spectral atlas consisting of spectra of 91 pre-main sequence stars. Most stars in this sample were observed with the Space Telescope Imaging Spectrograph (STIS) and Advanced Camera for Surveys (ACS) on the \emph{Hubble Space Telescope} (\emph{HST}). We find strong correlations among the \ion{O}{1} $λ$1304 triplet, %\ion{C}{2} $λ$1335, the \ion{Si}{4} $λλ$1394/1403 doublet, the \ion{C}{4} $λ$1549 doublet, and the \ion{He}{2} $λ$1640 line luminosities. For classical T Tauri stars (CTTSs), we also find strong correlations between these lines and the accretion luminosity, suggesting that these lines form in processes related to accretion. These FUV line fluxes and X-ray luminosity correlate loosely with large scatters. The FUV emission also correlates well with H$α$, H$β$, and \ion{Ca}{2} K line luminosities. These correlations between FUV and optical diagostics can be used to obtain rough estimates of FUV line fluxes from optical observations. Molecular hydrogen (H$_{2}$) emission is generally present in the spectra of actively accreting CTTSs but not the weak-lined T Tauri stars (WTTSs) that are not accreting. The presence of H$_2$ emission in the spectrum of HD 98800 N suggests that the disk should be classified as actively accreting rather than a debris disk. The spectra in the atlas are available at http://archive.stsci.edu/prepds/ttauriatlas.

description: Increasing attention has been paid to resources on islands, thus microgrids on islands need to be invested. Different from onshore microgrids, offshore microgrids (OM) are usually abundant in ocean renewable energy (ORE), such as offshore wind, tidal power generation (TPG), etc. Moreover, some special loads such as seawater desalination unit (SDU) should be included. In this sense, this paper proposes a planning method for OM to minimize the investment cost while the ORE's fluctuation could be accommodated with robustness. First, a deterministic planning model (DPM) is formulated for the OM with TPG and SDU. A robust planning model (RPM) is then developed considering the uncertainties from both TPG and load demand. The Column-and-constraint generation (C&CG) algorithm is then employed to solve the RPM, producing planning results for the OM that is robust against the worst scenario. Results of the case studies show that the investment and operation decisions of the proposed model are robust, and TPG shows good complementarity with the other RESs.
Safety on a Shrinking Margin: Manual Fallers, Uncertainty and Culture in the Southeastern B.C. Logging Industry

subject: Ethnography

description: In recent decades the rates of serious injuries and fatalities in the British Columbia logging industry have consistently remained higher than those in other dangerous workplaces, such as petroleum exploration and heavy construction, despite the implementation of technological improvements and safety awareness programs. Within the logging industry, manual tree fallers — workers who use chain-saws to fell trees — are the occupational category at greatest risk. Government inquests have suggested that the absence of a strong “safety culture” in the logging industry is a contributing factor in accident rates, but the inquests do not explain where the existing culture came from or how it might be changed. This dissertation presents an ethnographic study of manual tree fallers in the East Kootenay/Columbia region of British Columbia, focussed on the nature of their occupational culture and how it is perpetuated within their physical and social environment. The ensuing analysis draws on several areas of anthropological and social theory but throughout this thesis the emphasis is on the ethnographic material and on the perspectives of manual fallers and their colleagues. The ethnographic chapters focus on the organizational cultures of logging crews, the common experiences manual fallers have during their work tasks, as well as the economic and regulatory systems the industry operates within. This thesis argues that the occupational culture of manual fallers and the culture in the wider logging industry emerge mainly in response to continuous exposure to physical and financial uncertainty. Logging contractors and their employees, particularly manual fallers, assume that they cannot control important parts of their work and therefore their practices revolve around the trading off of alternative risks and an occupational tendency to keep several options available so that they can reduce the damage from hazardous events. In contrast, forest product companies and government agencies focus on control and respond to high accident rates by placing greater constraints on logging operations. However, by doing this, they reinforce loggers’ sense of uncertainty. The thesis concludes by discussing intervention strategies and suggesting how more effective workplace safety interventions might be achieved through partnerships between government agencies, forest product companies, and local loggers.
Comment on "Interaction of two solitary waves in quantum electron-positron-ion plasma" [Phys. Plasmas \textbf{18}, 052301 (2011)]

description: Recently, Yan-Xia Xu, et al. in the article Ref. [Phys. Plasmas \textbf{18}, 052301 (2011)] have studied the effects of various plasma parameters on interaction of two ion-acoustic solitary waves in an unmagnetized three-dimensional electron-positron-ion quantum plasma. They have used the extended reductive perturbation technique, the so-called, extended Poincare'-Lighthill-Kuo (PLK) technique, to deduce from the model governing the quantum hydrodynamics (QHD) differential equations leading to the soliton dynamical properties, namely, Korteweg-de Vries evolution equations (one for each wave) and coupled differential equations describing the phase-shift in trajectories of solitons due to the two dimensional collision. The variation of the calculated collision phase-shifts are then numerically inspected in terms of numerous plasma fractional parameters. In this comment we give some notes specific to the validity of the results of above-mentioned article and refer to important misconceptions about the use of the Fermi-temperature in quantum plasmas, appearing in this article and many other recently published ones.

description: Using a Levy process we generalize formulas in Bo et al. (2010) to the Esscher transform parameters for the log-normal distribution which ensures the martingale condition holds for the discounted foreign exchange rate. We also derive similar results, but in the case when the dynamics of the FX rate is driven by a general Merton jump-diffusion process. Using these values of the parameters we find a risk-neural measure and provide new formulas for the distribution of jumps, the mean jump size, and the Poisson process intensity with respect to this measure. The formulas for a European call foreign exchange option are also derived. We apply these formulas to the case of the log-double exponential and exponential distribution of jumps. We provide numerical simulations for the European call foreign exchange option prices with different parameters.

description: The excitation of quasi-particles near the extrema of the electronic band structure is a gateway to electronic phase transitions in condensed matter. In a many-body system, quasi-particle dynamics are strongly influenced by the electronic single-particle structure and have been extensively studied in the weak optical excitation regime. Yet, under strong optical excitation, where light fields coherently drive carriers, the dynamics of many-body interactions that can lead to new quantum phases remain largely unresolved. Here, we induce such a highly non-equilibrium many-body state through strong optical excitation of charge carriers near the van Hove singularity in graphite. We investigate the system's evolution into a strongly-driven photo-excited state with attosecond soft X-ray core-level spectroscopy. Surprisingly, we find an enhancement of the optical conductivity of nearly ten times the quantum conductivity and pinpoint it to carrier excitations in flat bands. This interaction regime is robust against carrier-carrier interaction with coherent optical phonons acting as an attractive force reminiscent of superconductivity. The strongly-driven non-equilibrium state is markedly different from the single-particle structure and macroscopic conductivity and is a consequence of the non-adiabatic many-body state.

description: We study local superspace contributions to low-energy effective action in general chiral three-dimensional superfield model. The effective Kahler and chiral potentials are computed in explicit form up to the two-loop order. In accordance with the non-renormalization theorem, the ultraviolet divergences appear only in the full superspace while the effective chiral potential receives only finite quantum contributions in the massless case. As an application, the two-loop effective scalar potential is found for the three-dimensional N=2 supersymmetric Wess-Zumino model.

Naturally small neutrino mass with asymptotic safety and gravitational-wave signatures

description: We revisit the dynamical generation of an arbitrarily small neutrino Yukawa coupling in the Standard Model with trans-Planckian asymptotic safety and apply the same mechanism to the gauged $B-L$ model. We show that thanks to the presence of additional irrelevant couplings, the described neutrino-mass generation in the $B-L$ model is potentially more in line with existing theoretical calculations in quantum gravity. Interestingly, the model can accommodate, in full naturalness and without extensions, the possibility of purely Dirac, pseudo-Dirac, and Majorana neutrinos with any see-saw scale. We investigate eventual distinctive signatures of these cases in the detection of gravitational waves from first-order phase transitions. We find that, while it is easy to produce a signal observable in new-generation interferometers, its discriminating features are washed out by the strong dependence of the gravitational-wave spectrum on the relevant parameters of the scalar potential.

Cortical Porosity in Bone

Publisher: name: Graduate Studies

subject: Cortical Porosity

description: Osteoporosis (porous bones) is a disease that is characterized by decreased bone strength and increased risk of fracture due to loss of bone strength from decreased bone mass and deterioration of bone micro-architecture. In particular, cortical porosity (CtPo) significantly impacts bone strength and has been associated with the progression of the disease and the occurrence of fracture. Very recently, it has become possible to assess CtPo in the appendicular skeleton in vivo through the use of high-resolution peripheral quantitative computed tomography (HR-pQCT). There are two approaches to assessing CtPo from HR-pQCT imaging data based on a threshold-based or a density-based approach. The performance of both methods was compared against gold-standard synchrotron radiation micro computed tomography (SRu CT) measurements. The threshold-based approach was found to be more highly correlated with true values of CtPo than a density-based approach. Improved CtPo measures may lead to better imaging diagnostics to detect and monitor osteoporosis.

description: The framed standard model (FSM) suggested earlier, which incorporates the Higgs field and 3 fermion generations as part of the framed gauge theory structure, is here developed further to show that it gives both quarks and leptons hierarchical masses and mixing matrices akin to what is experimentally observed. Among its many distinguishing features which lead to the above results are (i) the vacuum is degenerate under a global $su(3)$ symmetry which plays the role of fermion generations, (ii) the fermion mass matrix is "universal", rank-one and rotates (changes its orientation in generation space) with changing scale $μ$, (iii) the metric in generation space is scale-dependent too, and in general non-flat, (iv) the theta-angle term in the QCD action of topological origin gets transformed into the CP-violating phase of the CKM matrix for quarks, thus offering at the same time a solution to the strong CP problem.

Music as a "language" of expression for understanding multiplication in grade three
Creators: name: Moriarty, Corry Suzanne
Publisher: name: University of British Columbia
Year: 2010

description: Abstract This study explored how music could be used as a language of expression for understanding multiplication for grade three children. Using a/r/tography as a research methodology, a class of grade three students, their teacher, and I worked together on a coemergent inquiry project to create musical compositions that conveyed meanings about multiplication to the listener. The design of this a/r/tographic inquiry involves the components of the cyclical Inquiry Process used by the International Baccalaureate program, as well as the Reggio Emilia’s approach, known as Progettazione, which involves emergent, child centered project work. Through my research I offer credence to the area of interdisciplinary studies at the early childhood level. Such studies support the development of new notions and forms of music instruction—created by and for children—that advance both music and related learning. As is evident in my account, I demonstrated how music (1) can be taught in and of itself, (2) can be thought of as a medium (i.e., a “language,” as in the Reggio definition) for the expression of concepts in multiplication, (3) is instrumental in fostering knowledge of both musical and mathematical concepts, and (4) when linked with mathematics, can show learning transfer and access related learning between the two disciplines. This study contributes to on-going scholarly conversations concerning the present structure and role of the music teacher (and other “specialists”) in our schools.
CO Oxidation in the Presence of Claus Tail Gas Species over Au/RE2O3-TiO2 Catalysts

description: At present most tail gas incineration units operate at 973 K to oxidize CO. Catalytic incineration offers an economic advantage as a result of lower operating temperatures; however, the catalysts in use to date, are not efficient for oxidation of CO and H2 in presence of sulfur species. Mixed metal oxide supported gold nanoparticles have received considerable attention regarding CO oxidation. This study focuses on synthesizing catalysts operational under Claus tail gas incineration that involves high concentration of sulfur species and water. Gold nano-particles supported on TiO2 doped with rare earth oxide (i.e., La, Eu, Er) catalysts were synthesized and compared against the well-known Au/TiO2 catalyst through characterization and catalytic activity analyses. XPS data pointed to the presence of electron-rich gold nanoparticles. The catalytic activity results showed a relatively superior catalytic activity of Au/Eu2O3−TiO2 for CO oxidation in the presence of sulfur species. However, the synthesized Au/RE2O3-TiO2 catalysts have not been able to significantly out-perform Au/TiO2 catalyst.

description: Discrete-variable (DV) and continuous-variable (CV) schemes constitute the two major families of quantum key distribution (QKD) protocols. Unfortunately, since the setup elements required by these schemes are quite different, making a fair comparison of their potential performance in particular applications is often troublesome, limiting the experimenters' capability to choose an optimal solution. In this work we perform a general comparison of the major entanglement-based DV and CV QKD protocols in terms of their resistance to the channel noise, with the otherwise perfect setup, showing the definite superiority of the DV family. We analytically derive fundamental bounds on the tolerable channel noise and attenuation for entanglement-based CV QKD protocols. We also investigate the influence of DV QKD setup imperfections on the obtained results in order to determine benchmarks for the parameters of realistic photon sources and detectors, allowing the realistic DV protocols to outperform even the ideal CV QKD analogs. Our results indicate the realistic advantage of DV entanglement-based schemes over their CV counterparts and suggests the practical efforts for maximizing this advantage.

description: Antiperovskites are a rich family of compounds with applications in battery cathodes, superconductors, solid-state lighting, and catalysis. Recently, a novel series of antimonide phosphide antiperovskites (A$_3$SbP, where A = Ca, Sr, Ba) were proposed as candidate photovoltaic absorbers due to their ideal band gaps, small effective masses and strong optical absorption. In this work, we explore this series of compounds in more detail using relativistic hybrid density functional theory. We reveal that the proposed cubic structures are dynamically unstable and instead identify a tilted orthorhombic Pnma phase as the ground state. Tilting is shown to induce charge localisation that widens the band gap and increases the effective masses. Despite this, we demonstrate that the predicted maximum photovoltaic efficiencies remain high (24-31% for 200 nm thin films) by bringing the band gaps into the ideal range for a solar absorber. Finally, we assess the band alignment of the series and suggest hole and electron contact materials for efficient photovoltaic devices.

To block the monitoring system in the internet the attackers are targeted the ITM system. In this paper we address the flooding attack of DDoS against ITM monitors to exhaust the network resources, such as bandwidth, computing power, or operating system data structures by sending the malicious traffic. We propose an information-theoretic frame work that models the flooding attacks using Botnet on ITM. One possible way to counter DDoS attacks is to trace the attack sources and punish the perpetrators. we propose a novel traceback method for DDoS using Honeypots. IP tracing through honeypot is a single packet tracing method and is more efficient than commonly used packet marking techniques.

description: A solid oxide fuel cell (SOFC) is an energy conversion device, which directly converts chemical fuels (e.g., H2, CxHy) into electricity and heat with high efficiency up to 90%. The byproduct of CO2 can be safely sequestrated or subsequently chemically transformed back into fuels(e.g., CO, CH4) by electrolysis using renewable energy sources such as solar and wind. The stateof-the-art Ni-YSZ anode is de-activated in the presence of ppm level of H2S and forming coke in hydrocarbons. Currently, mixed ion and electron conductors (MIECs) are considered as alternatives for Ni-YSZ in SOFCs. The key goal of the research was to develop mixed ion-electron conducting metal oxides based on B-site disordered perovskite-type Ba(Ca,Nb)1-xMxO3-δ (M = Mn, Fe, Co), the B-site 1:1 ordered perovskite-type (M = Mn, Fe, Co) and the Sr2PbO4-type Sr2Ce1-xPrxO4 for SOFCs. Ba2(Ca,Nb)2-xMxO6-δ was chemically stable in 30 ppm levels of H2S at 600 °C for 24 h and in pure CO2 at 800 °C for 24 h. The thermal expansion coefficients (TEC) of the as-prepared ordered perovskites was found to be comparable to Zr0.84Y0.16O1.92 (YSZ). The near-surface concentration of Fe2+ in Ba2Ca0.67Fe0.33NbO6-δ was found to be about 3 times higher than that in the bulk sample. The electrochemical performance of Ba2Ca0.67M0.33NbO6-δ was assessed by ac impedance spectroscopy using a YSZ supported half-cell. The area specific polarization resistance (ASR) of all samples was found to decrease with increasing temperature. The ASR for H2 gas oxidation can be correlated to the higher concentration of low valence Fe2+ species near-surface (nano-scale). BaCa0.335M0.165Nb0.5O3-δ crystallizes in the B-site disordered primitive perovskite (space group Pm-3m) at 900 °C in air, which can be converted into the B-site 1:2 ordered perovskite (space group P-3m1) at 1200 °C and the B-site 1:1 ordered double perovskite phase (space groupFm-3m) at 1300 °C. The chemical stability of the perovskites in CO2 and H2 highly depends on the B-site cations ordering. The B-site disordered primitive perovskite phase is more readily reduced in dry and 3% H2O in 10% H2 balanced with 90% N2, and is less stable in CO2 at elevated temperatures, compared to the B-site 1:1 ordered double perovskite phase. The thermal decomposition is highly suppressed in Sr2Ce1−xPrxO4 compounds for Pr > 0, suggesting that Pr improves the thermal stability of the compounds. Rietveld analysis of PXRD and SAED supported that both Pr and Ce ions are located on the 2a site in Pbam. Conductivity increases with Pr content in Sr2Ce1−xPrxO4. The highest total conductivity of 1.24 x 10−1 S cm−1 was observed for Sr2Ce0.2Pr0.8O4 at 663 °C in air.

description: This research sought to influence clinical management and treatment of Achilles tendinopathy by: 1) evaluating the efficacy of sclerotherapy (with a 25% dextrose and 0.5% lidocaine sclerosant) over the course of one year; 2) evaluating the effectiveness of a 12 week standardized home based heavy load eccentric training program; and 3) describing the prevalence of neovascularisation in adults with disease and without, and prevalence after treatment. Specifically, it provides the first short term data from a prospective triple blinded randomized controlled trial on the efficacy of ultrasound guided sclerosing 25% dextrose and 0.5% lidocaine injections following failure of eccentric exercises. Sclerotherapy was an efficacious treatment in the short term (3 months) with all patients showing statistically significant improvement in pain and function (as measured by the Victorian Institute of Sport Assessment-Achilles outcome measure), but its positive effects decreased for some patients after one year. With regards to neovascularisation, it was present in all affected tendons (and in one individual without the disease), but change in the number of neovessels does not appear to affect symptoms. With regard to eccentric training, it was found to not be effective in the majority of patients with only two patients considering themselves satisfied with treatment. Based on these results, a treatment paradigm and future research directions are provided. Most notably, eccentric training is not recommended as an effective treatment option for Achilles tendinopathy. Sclerotherapy is recommended as a treatment option for both mid-portion and enthesopathy.

description: In most star formation history (SFH) measurements, the reported uncertainties are those due to effects whose sizes can be readily measured: Poisson noise, adopted distance and extinction, and binning choices in the solution itself. However, the largest source of error, systematics in the adopted isochrones, is usually ignored and very rarely explicitly incorporated into the uncertainties. I propose a process by which estimates of the uncertainties due to evolutionary models can be incorporated into the SFH uncertainties. This process relies on application of shifts in temperature and luminosity, the sizes of which must be calibrated for the data being analyzed. While there are inherent limitations, the ability to estimate the effect of systematic errors and include them in the overall uncertainty is significant. Effects of this are most notable in the case of shallow photometry, with which SFH measurements rely on evolved stars.

description: The Fourth Industrial Revolution, ushered by the deeper integration of digital technologies into professional and social spaces, provides an opportunity to meaningfully serve society. Humans have tremendous capability to innovatively improve social well-being when the situation is clear. Which was not the case during the first three revolutions. Thus, society has been accepting lifestyle changes willingly and several negative consequences unwillingly. Since the fourth one is still in its infancy, we can control it better. This paper presents a unified model of the industrialized ecosystem covering value creation, value consumption, enabling infrastructure, required skills, and additional governance. This design thinking viewpoint, which includes the consumer side of digital transformation, sets the stage for the next major lifestyle change, termed Digital Transfiguration. For validation and ease of comprehension, the model draws upon the well-understood automobile industry. This model unifies the digital penetration of both industrial creation and social consumption, in a manner that aligns several stakeholders on their transformation journey.

description: At the beginning, this thesis proposes an algorithm inspired by ant's scout-and-recruit for foraging providing a low-cognition algorithm to rescue civilians in distress and explaining how it could be achieved. Being low-cognition algorithm, this algorithm is characterized by having minimal computation and communication between the agents of the MAS as well as being applicable for large scale environment due to its inspiration from ants. Then, an algorithm inspired by human's conformity is provided which is considered a high-cognition algorithm. This algorithm is applied to a rescue mission that is simulated using \emph{RoboCup Rescue Simulator}. Being high-cognition algorithm, this algorithm is characterized by having heavy computation and communication made by the agents of the MAS. Finally, the conformity algorithm is integrated on top of the scout-and-recruit algorithm to enhance its performance. While the low-cognition part insures its applicability to large scale, the high-cognition algorithm pushes the agents to make smarter decisions enhancing the overall system performance.

description: Predator Free 2050 (PF2050) is an ambitious goal that aims to remove three types of invasive mammals from New Zealand by 2050. It will require a significant amount of funding, research, and support. Young adults will have an important role to play for this programme to be successful. Therefore, understanding the awareness and attitudes of young adults towards PF2050, and predator control, is an essential consideration. A survey of 1479 18- to 24-year-olds was conducted in 2017. The results showed that a higher percentage of young adults than members of the broader public view the small, introduced mammals as threats to New Zealand’s environment. Furthermore, this study highlights support for the control of feral, stray, and domestic cats. More focused research on attitudes towards cats is recommended to gauge which control methods are approved of by young adults. Indeed, methods appear to be a key factor to young adults supporting PF2050. The aerial distribution of poison was largely viewed negatively, and moderate concern was expressed about the targeted animal’s welfare. Interestingly, young adults appeared to be open to the use of gene editing and gene drive, although they expressed caution. Targeted communication towards young adults on toxins and genetic methods is recommended.

description: We introduce a detection scheme for the state of a qubit, which is based on resonant few-photon transitions in a driven nonlinear resonator. The latter is parametrically coupled to the qubit and is used as its detector. Close to the fundamental resonator frequency, the nonlinear resonator shows sharp resonant few-photon transitions. Depending on the qubit state, these few-photon resonances are shifted to different driving frequencies. We show that this detection scheme offers the advantage of small back action, a large discrimination power with an enhanced read-out fidelity, and a sufficiently large measurement efficiency. A realization of this scheme in the form of a persistent current qubit inductively coupled to a driven SQUID detector in its nonlinear regime is discussed.

description: Demand response is an attractive topic due to the opportunities offered by the coming of Smart Grid, and increasing concern of greenhouse gas emissions. To increase the responsiveness of demand, residential energy management systems (REMS) have been proposed to automate and schedule electric energy consumption within a dwelling. This work addresses several challenges and implications associated to REMS in the electricity grid. First, this work presents a framework for modelling residential electric load and tariff structures for creating optimal consumption schedules for electrical devices in a dwelling. Second, this work provides a framework for evaluating a multi-criteria performance of REMS, and compares the performance of REMS under various electricity tariff structures. Third, this work presents two scheduling algorithms that reduces the impact of scheduling errors and provides analysis on the improvement on computational tractability. Numerical simulations based on real-life data are provided. Each of the simulations includes optimizing the energy consumption patterns of several load types, subject to forecasting errors and variable electricity prices. The results allow us to describe the trade-offs between solution quality and various parameters.

description: Size-exclusion chromatography (SEC) coupled to an inductively coupled plasma atomic emission spectrometer (ICP-AES) was employed to study the effect of the human serum albumin (HSA) concentration on the metabolism of cisplatin (CP) in human blood plasma in vitro. Plasma from 14 healthy adults and 11 pediatric cancer patients was spiked with CP and the Pt distribution was determined at the 5 min and 2 hr time point. The results revealed that as the HSA concentration decreased, the percent of Pt-bound to HSA decreased; whereas the percent of Pt-hydrolysis products increased, while other Pt-species were largely unaffected. These changes were corroborated by fortifying the cancer patient plasma with HSA to healthy concentrations followed by the addition of CP. In summary, these findings imply that the infusion of cancer patients with HSA to healthy plasma levels may decrease the fraction of free hydrolysis products, which may alleviate the severe toxic side effects of CP.
