description: We present a fully relativistic calculation of the matter bispectrum at second order in cosmological perturbation theory assuming a Gaussian primordial curvature perturbation. For the first time we perform a full numerical integration of the bispectrum for both baryons and cold dark matter using the second-order Einstein-Boltzmann code, SONG. We review previous analytical results and provide an improved analytic approximation for the second-order kernel in Poisson gauge which incorporates Newtonian nonlinear evolution, relativistic initial conditions, the effect of radiation at early times and the cosmological constant at late times. Our improved kernel provides a percent level fit to the full numerical result at late times for most configurations, including both equilateral shapes and the squeezed limit. We show that baryon acoustic oscillations leave an imprint in the matter bispectrum, making a significant impact on squeezed shapes.

In the pursuit of sons: sex-selective abortion and differential stopping in Pakistan
Creators: name: Zaidi, Rukh-e-Batool
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: Even though Pakistan is a highly patriarchal society, it has not featured prominently in studies focusing on son preference and sex ratios at birth. But with fertility declining and given strong son preference (Pakistan has one of the highest desired sex ratios in the world), how will Pakistani families respond? Using data for 2006-07, I show clear evidence of both sex selection practice and differential stopping behavior. An earlier survey (1990-91) shows only modest evidence of differential stopping behavior. The comparison of the two survey rounds also supports the increasing role of son preference in fertility behavior in Pakistan. With increasing access to contraceptive and sex selection technology, both differential stopping and sex selection are likely to continue increasing for some time.

description: The problem of scattering of harmonic plane acoustic waves by fluid spheroids (prolate and oblate) is addressed from an analytical approach. Mathematically, it consists in solving the Helmholtz equation in an unbounded domain with Sommerfeld radiation condition at infinity. The domain where propagation takes place is characterised by density and sound speed values $ρ_0$ and $c_0$, respectively, while $ρ_1$ and $c_1$ are the corresponding density and sound speed values of an immersed object that is responsible of the scattered field. Since Helmholtz equation is separable in prolate/oblate spheroidal coordinates, its exact solution for the scattered field can be expressed as an expansion on prolate/oblate spheroidal functions multiplied by coefficients whose values depend upon the boundary conditions verified at the medium-immersed fluid obstacle interface. The general case ($c_0 \neq c_1$) is cumbersome because it requires to solve successive matrix systems that are ill-conditioned when $c_1/c_0$ is far from unity. In this paper, a numerical implementation of the general exact solution that is valid for any range of eccentricity values and for $c_0 \neq c_1$, is provided. The high level solver code has been written in the Julia programming language while a software package recently released in the literature has been used to compute the spheroidal functions. Several limit cases (Dirichlet and Neumann boundary conditions, spheroid tending to sphere) have been satisfactorily verified using the implemented code. The corresponding example scripts can be downloaded from the authors' web (GitHub) site. Additionally, the new code has been used to extend results reported in the literature.

description: We consider a macroscopic quantum system in a tilted double-well potential. By solving Hamiltonian equation, we obtain tunneling probabilities which contain oscillation effects. To show how one can decide between quantum mechanics and the implications of macrorealism assumption, a given form of Leggett-Garg inequality is used. The violation of this inequality occurs for a broader range of decoherence effects, compared to previous results obtained for two-level systems.

description: TGFβs, BMPs and Activins regulate numerous developmental and homeostatic processes and signal through hetero-tetrameric receptor complexes composed of two types of serine/threonine kinase receptors. Each of the 33 different ligands possesses unique affinities towards specific receptor types. However, the lack of specific tools hampered simultaneous testing of ligand binding towards all BMP/TGFβ receptors. Here we present a N-terminally Halo- and SNAP-tagged TGFβ/BMP receptor library to visualize receptor complexes in dual color. In combination with fluorescently labeled ligands, we established a Ligand Surface Binding Assay (LSBA) for optical quantification of receptor-dependent ligand binding in a cellular context. We highlight that LSBA is generally applicable to test (i) binding of different ligands such as Activin A, TGFβ1 and BMP9, (ii) for mutant screens and (iii) evolutionary comparisons. This experimental set-up opens opportunities for visualizing ligand-receptor binding dynamics, essential to determine signaling specificity and is easily adaptable for other receptor signaling pathways.
Superfluid behavior of quasi-1D p-H$_2$ inside carbon nanotube

description: We perform ab-initio Quantum Monte Carlo simulations of para-hydrogen (pH$_2$) at $T=0$ K confined in carbon nanotubes (CNT) of different radii. The radial density profiles show a strong layering of the pH$_2$ molecules which grow, with increasing number of molecules, in solid concentric cylindrical shells and eventually a central column. The central column can be considered an effective one-dimensional (1D) fluid whose properties are well captured by the Tomonaga-Luttinger liquid theory. The Luttinger parameter is explicitly computed and interestingly it shows a non-monotonic behavior with the linear density similar to what found for pure 1D $^3$He. Remarkably, for the central column in a (10,10) CNT, we found an ample linear density range in which the Luttinger liquid is (i) superfluid and (ii) stable against a weak disordered external potential, as the one expected inside realistic pores. This superfluid behavior could be experimentally revealed in bundles of carbon nanotubes, where deviations from classical inertial values associated with superfluid density could be measured via torsional oscillator techniques. In summary, our results suggest that pH$_2$ within carbon nanopores could be a practical realization of the long sought-after, elusive superfluid phase of parahydrogen.

Charge quantization from a number operator

description: We explain how an unexpected algebraic structure, the division algebras, can be seen to underlie a generation of quarks and leptons. From this new vantage point, electrons and quarks are simply excitations from the neutrino, which formally plays the role of a vacuum state. Using the ladder operators which exist within the system, we build a number operator in the usual way. It turns out that this number operator, divided by 3, mirrors the behaviour of electric charge. As a result, we see that electric charge is quantized because number operators can only take on integer values. Finally, we show that a simple hermitian form, built from these ladder operators, results uniquely in the nine generators of $SU(3)_c$ and $U(1)_{em}$. This gives a direct route to the two unbroken gauge symmetries of the standard model.

description: As obesity rates have risen around the world, so to have pregnancies complicated by maternal obesity. Obesity during pregnancy is not only associated with negative health outcomes for the mother and the baby during pregnancy and birth, there is also strong evidence that exposure to maternal obesity causes an increased risk to develop obesity, diabetes and cardiovascular disease later in life. Animal models have demonstrated that increased weight gain in offspring exposed to maternal obesity is usually preceded by increased food intake, implicating altered neuronal control of food intake as a likely area of change. The hypothalamus is the primary site in the brain for maintaining energy homeostasis, which it coordinates by sensing whole body nutrient status and appropriately adjusting parameters including food intake. The development of the hypothalamus is plastic and regulated by metabolic hormones such as leptin, ghrelin and insulin, making it vulnerable to disruption in an obese in utero environment. This review will summarise how the hypothalamus develops, how maternal obesity impacts on structure and function of the hypothalamus in the offspring, and the factors that are altered in an obese in utero environment that may mediate the permanent changes to hypothalamic function in exposed individuals.

description: We consider spectral sequences in smooth generalized cohomology theories, including differential generalized cohomology theories. The main differential spectral sequences will be of the Atiyah-Hirzebruch (AHSS) type, where we provide a filtration by the Cech resolution of smooth manifolds. This allows for systematic study of torsion in differential cohomology. We apply this in detail to smooth Deligne cohomology, differential topological complex K-theory, and to a smooth extension of integral Morava K-theory that we introduce. In each case we explicitly identify the differentials in the corresponding spectral sequences, which exhibit an interesting and systematic interplay between (refinement of) classical cohomology operations, operations involving differential forms, and operations on cohomology with U(1) coefficients.

Modulation of interleukin-8 protein expression by micro-RNA 181 in human pulpal fibroblasts
Creators: name: Galicia, Johnah
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: MicroRNAs (miRNA) regulate the synthesis of cytokines in response to Toll-like receptor (TLR) activation. miRNA-181 is differentially expressed in pulpitis, which represents an immune reaction to bacteria and is also the most common cause of emergency room visits due to dental pain. We employed an in-vitro model to determine the role of miRNA in pulpitis, which has been shown in several studies to overexpress Interleukin-8 (IL-8). Primary human dental pulp fibroblasts (HDPF) were stimulated with the TLR-2/4 agonist P. gingivalis lipopolysaccharide. An inversely proportional relationship between IL-8 and miRNA-181a was observed, which was validated by in-silico identification of a miR-181a binding site on the 3'UTR of IL-8 and by dual-luciferase assays. This is the very first report demonstrating miR-181a regulation of IL-8. Considering that both mir-181 and IL-8 have been implicated in various systemic conditions, the findings of this study extend well beyond the confines of Endodontics.
Black Power GIs: How the Rising Storm of Radical Black Masculinity in the Vietnam War Shaped Military Perceptions of African-American Soldiers
Creators: name: Dong, Cheryl Xue
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: During the Vietnam War, a new generation of African-American men entered the military. These young soldiers grew up in the crucible of the Civil Rights Movement and brought new expectations of racial equality to the military. At the same time, an escalating war in Vietnam and the racial inequity of the draft caused many soldiers to turn to radical expressions of black masculinity. These demonstrations of radical black masculinity renegotiated meanings of citizenship and military service for young, African-American men. These soldiers questioned the traditional narrative that military service could serve as a path to American citizenship and even questioned the value of American citizenship itself. These soldiers explored alternatives to American citizenship through experimentation with black nationalism and black power. After the Vietnam War, the military had to re-think the relationship of military service to American citizenship itself. In a nation without the draft, military service could no longer be the ultimate test of masculine citizenship. Instead, the military had to re-package itself as economic opportunity instead of patriotic duty.

description: The brine barrier remediation technique (BBRT) has been proposed as a novel Brine barrier remediation techniques (BBRT) that use surfactants have been proposed for remediating subsurface environments contaminated by dense non-aqueous phase liquids (DNAPLs). Their successful implementation requires an understanding of surfactant phase behavior including surfactant accumulation at the water/DNAPL interface and surfactant precipitation due to the presence of high aqueous-phase concentrations of brine. Multiscale modeling based upon thermodynamics and molecular dynamics (MD) was performed to investigate surfactant precipitation and molecular details at the surfactant-modified water/DNAPL interface. While these modeling results advance the understanding of surfactant behavior, a few open issues must be addressed before these new methods can be considered reliable and mature.

description: We describe 2016 January to April observations of the fragments of 332P/Ikeya-Murakami, a comet earlier observed in a 2010 October outburst (Ishiguro et al 2014). We present photometry of the fragments, and perform simulations to infer the time of breakup. We argue that the eastern-most rapidly brightening fragment ($F4$) best corresponds to the original nucleus, rather than the initial bright fragment $F1$. We compute radial and tangential non-gravitational parameters, $A_1 = (1.5 \pm 0.4) \times 10^{-8}$ AU day$^{-2}$ and $(7.2 \pm 1.9) \times 10^{-9}$ AU day$^{-2}$; both are consistent with zero at the $4σ$ level. Monte Carlo simulations indicate that the fragments were emitted on the outbound journey well after the 2010 outburst, with bright fragment $F1$ splitting in mid--2013 and the fainter fragments within months of the 2016 January recovery. Western fragment $F7$ is the oldest, dating from 2011. We suggest that the delayed onset of the splitting is consistent with a self-propagating crystallization of water ice.

description: A Multipartite entangled state has many different kinds of entanglement specified by the number of partitions. The most essential example of multipartite entanglement is the entanglement of multi-qubit Greenberger-Horne-Zeilinger (GHZ) state in white noise. We explicitly construct the entanglement witnesses for these states with stabilizer generators of the GHZ states. For a $N$ qubit GHZ state in white noise, we demonstrate the necessary and sufficient criterion of separability when it is divided into $k$ parties with $N\leq 2k-1$ for arbitrary $N$ and $k$. The criterion covers more than a half of all kinds of partial entanglement for $% N $-qubit GHZ states in white noise. For the rest of multipartite entanglement problems, we present a method to obtain the sufficient conditions of separability. As an application, we consider $N$ qubit GHZ state as a codeword of the degenerate quantum code passing through depolarizing channel. We find that the output state is neither genuinely entangled nor fully separable when the quantum channel capacity reduces from positive to zero.

Within this model, we discuss an analytic solution and explore it in the context of previously known results. We discuss the existence of one-dimensional domain walls localized on two-dimensional ones, and construct the corresponding effective action. In the low-energy limit, which is the $\mathbb{O}(3)$ sigma-model, we discuss the existence of skyrmions localized on domain walls, and provide a solution for a skyrmion configuration, based on an analogy with instantons. We perform symmetry analysis of the initial model and of the low-energy theory on the domain wall world volume.

Determination of Aliphatic Amines in Urine as Biomarkers of Exposure to 1,6-hexamethylene Diisocyanate and Isocyanurate
Creators: name: Robbins, Zachary G.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: Biological monitoring of 1,6-hexamethylene diisocyanate (HDI) exposure has been limited to the hydrolysis product of HDI monomer. The determination of acetylated 1,6- diaminohexane (HDA) and isotriamine as biomarkers of HDI and isocyanurate exposure, respectively, can provide important insight into the metabolism and dose-response relationships of these compounds. The objective of this study was to develop a liquid chromatography-mass spectrometry (LC-MS) method to detect HDA, monoacetyl-HDA, diacetyl-HDA, and isotriamine in urine. The LC-MS method was developed using the four standards spiked into urine at concentrations between 0.019-10.144 μg/L. Quantification of serial dilutions of the standards in urine was performed using selected reaction monitoring on a triple quadrupole mass spectrometer. The limit of detection and the limit of quantification in spiked urine were 0.01 and 0.02 μg/L for monoacetyl-HDA, respectively, and 0.16 and 0.31 μg/L for diacetyl-HDA, respectively. HDA and isotriamine were not detectable in urine at concentrations below 10 μg/L because of high background level of other unspecified compounds. The developed LC-MS method is sensitive and specific for the quantification of acetylated metabolites of HDI. However, modifications to the method are necessary to improve the specificity and sensitivity of HDA and isotriamine analyses.

description: $Λ$-Warm Dark Matter (WDM) has been proposed as alternative scenario to $Λ$ cold dark matter (CDM), motivated by discrepancies at the scale of dwarf galaxies, with less small-scale power and realized by collisionless particles with energies in the range $1-3$ keV. We present a new approach to constrain the viability of such WDM models using star formation histories of the dwarf spheroidal galaxies (dSphs) in the Local Group. We compare their high time-resolution star formation histories (SFHs) obtained with HST-based color magnitude diagrams with the range of possible collapse redshifts of their dark matter halos expected in CDM and in different WDM scenarios. The collapse redshift is inferred after determining a plausible infall mass of the subhalo. This is based on the current mass of individual dwarf inferred from stellar kinematics combined with results of cosmological simulations providing information on the subhalo evolution. Since WDM subhalos close to the filtering mass scale form significantly later than CDM, we show that they are in the first place difficult to reconcile with a truncation of star formation occurring as early as $z\geq 3$. The Ultra-Faint Dwarfs (UFDs) provide the most stringent constraints. Using 6 UFDs with the best determination of the SFHs, we show that we can exclude a 1 keV warm particle to a 2-$σ$ confidence interval consistently with other methods reported in the literature. For some objects the $2$ keV model is also excluded. We discuss the various caveats of the method, most notably the low number of dwarfs with accurately determined star formation histories and the uncertainties in the determination of the infall mass of the subhalos. Our preliminary analysis serves as a pathfinder for future investigations that will combine upcoming accurate SFHs for more local dSphs with direct analysis of WDM cosmological simulations with baryons.

description: As the name suggests, type-logical grammars are a grammar formalism based on logic and type theory. From the prespective of grammar design, type-logical grammars develop the syntactic and semantic aspects of linguistic phenomena hand-in-hand, letting the desired semantics of an expression inform the syntactic type and vice versa. Prototypical examples of the successful application of type-logical grammars to the syntax-semantics interface include coordination, quantifier scope and extraction.This chapter describes the Grail theorem prover, a series of tools for designing and testing grammars in various modern type-logical grammars which functions as a tool .

Macrostate equivalence of two general ensembles and specific relative entropies

description: The two criteria of ensemble equivalence, i.e. the macrostate equivalence and the measure equivalence, are investigated for a general pair of states. The macrostate equivalence implies the two ensembles are indistinguishable by the measurement of macroscopic quantities obeying the large-deviation principle, and the measure equivalence means that the specific relative entropy of these two states vanishes in the thermodynamic limit. It is shown that the measure equivalence implies the macrostate equivalence for a general pair of states by deriving an inequality connecting the large-deviation rate functions to the specific relative Renyi entropies. The result is applicable to both quantum and classical systems. As applications, a sufficient condition for thermalization, the timescale of quantum dynamics of macrovariables, and the second law with strict irreversibility in a quantum quench are discussed.

Storytelling ability and mate attraction
Creators: name: Donahue, John K.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Relationship research examines what traits affect mate attraction. Green and Brock's theory of Transportation into the Narrative World suggests an author can immerse a reader into a narrative, and effective storytelling could be a positive influence on mate attraction by inducing effects such as excitement. The following studies examined the effect of storytelling ability on perceptions of a person's physical attractiveness, attractiveness as a casual date, as a long-term date, and as a friend. In Study 1, information about a potential mate's storytelling ability was provided. In Study 2, good and poor stories were provided to assess attraction. The results of both studies suggest that only females' attractiveness assessments of males as a long-term date increased for good versus poor storytellers. In Study 3, the results suggest that the effect of storytelling ability on long-term attractiveness for males may be mediated by perceived status of the potential mate.

Water Committee Activities and Characteristics Affecting Water System Management in Northern Ghana
Creators: name: Fechter, Allison

Year: 2017

description: Water committees are believed to play an important role in managing community water systems in rural Africa. While past research suggests a relationship between water committee effectiveness and long-term sustainability of water systems, the relationship between committee activities and improved management outcomes is unclear. This study examines survey data from 124 communities in Northern Ghana. Two statistical models were developed to analyze the effect of water system management on water point functionality and user satisfaction with water service. Holding community meetings, practicing non-monetary resource mobilization, and preparing maintenance schedules were indicators of better management. Although existing research mostly focuses on pre-construction participation, these results highlight the role that water committees can play in engaging community members after construction is complete. Additionally, the supporting environmental factors of (a) access to tools and spare parts, (b) access to outside support, and (c) training were associated with improved outcomes.

description: We have fabricated ultra-thin YBa2Cu3O7-x nanowires with a high critical current density and studied their voltage switching behavior in the 4.2 - 90 K temperature range. A comparison of our experimental data with theoretical models indicates that, depending on the temperature and nanowire cross section, voltage switching originates from two different mechanisms: hotspot-assisted suppression of the edge barrier by the transport current and the appearance of phase-slip lines in the nanowire. Our observation of hotspot-assisted voltage switching is in good quantitative agreement with predictions based on the Aslamazov-Larkin model for an edge barrier in a wide superconducting bridge.

description: The theory of dependency graphs is a powerful toolbox to prove asymptotic normality of sums of random variables. In this article, we introduce a more general notion of weighted dependency graphs and give normality criteria in this context. We also provide generic tools to prove that some weighted graph is a weighted dependency graph for a given family of random variables. To illustrate the power of the theory, we give applications to the following objects: uniform random pair partitions, the random graph model $G(n,M)$, uniform random permutations, the symmetric simple exclusion process and multilinear statistics on Markov chains. The application to random permutations gives a bivariate extension of a functional central limit theorem of Janson and Barbour. On Markov chains, we answer positively an open question of Bourdon and Vallée on the asymptotic normality of subword counts in random texts generated by a Markovian source.

description: A novel phosphine-free pyrimidine-based palladium(II) complex have been synthesized from easily accessible starting materials and its ability to be a catalyst for cross-coupling reactions namely, Suzuki-Miyaura (SMC) has been investigated. The structure of the new formamidinyl pyrimidine-based complex has been elucidated by using spectroscopic as well as physical characterization techniques. The novel palladium(II) complex showed its applicability as a catalyst for SMC of 2-bromothiophene and 2,5-dibromothiophene with arylboronic acids under conventional and microwaves irradiation conditions. The developed catalytic system exhibited reasonable catalytic activity to obtain 2-aryl and 2,5-diarylthiophene derivatives using mild reaction conditions.

An Offer You Can't Refuse: Private Security and State Protection in Post-Soviet Russia
Creators: name: Cooke, Dawes
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: It is typically the responsibility of governments to safeguard the rights, property, and physical safety of its citizens. However, in Russia, as in many other countries, private organizations exist which operate as profitable businesses by offering these same protections to paying clients. Such organizations generally exist in a niche created by a government's inability or unwillingness to provide such protections and to monopolize the provision of them. Yeltsin's reforms in the aftermath of the Soviet collapse often left small businesses unprotected, leading to a rapid growth in the private security industry. However, as the central government strengthened and the economy improved under Putin, the industry continued to grow at a rapid pace thanks to adaptation by the private security industry to changes in demand for protection as well as cooption methods utilized by the state security structures.

description: We present a sample of accreting supermassive black holes (SMBHs) in dwarf galaxies at $z<1$. We identify dwarf galaxies in the NEWFIRM Medium Band Survey with stellar masses $M_{\star}<3\times 10^{9} M_{\odot}$ that have spectroscopic redshifts from the DEEP2 survey and lie within the region covered by deep (flux limit of $\sim 5\times 10^{-17} - 6\times 10^{-16} \rm{erg \ cm}^{-2} \ \rm{s}^{-1}$) archival Chandra X-ray data. From our sample of $605$ dwarf galaxies, $10$ exhibit X-ray emission consistent with that arising from AGN activity. If black hole mass scales roughly with stellar mass, then we expect that these AGN are powered by SMBHs with masses of $\sim 10^5-10^6 \ M_{\odot}$ and typical Eddington ratios $\sim 5\%$. Furthermore, we find an AGN fraction consistent with extrapolations of other searches of $\sim 0.6-3\%$ for $10^9 \ M_{\odot} \leq M_{\star} \leq 3\times 10^{9} \ M_{\odot}$ and $0.1

description: 3-(Naphthalen-1-yl)-2-thioxo-2,3-dihydroquinazolin-4(1H)-one 1, and its S-alkylated products 2–6, were effectively synthesized under ultrasonic irradiation under greener reaction condition with lower amount of solvent and in shorter reaction time to afford higher yield of the targeted compounds. 1H and 13C NMR, %CHN and FT-IR confirmed the structure of the synthesized products. The theoretical DFT calculations were carried out to study the electronic effect of the S-alkylated group on the structural as well as the thermal parameters for the investigated compounds. Further, the partition coefficient and other molecular properties of compounds 1–6 and their molecular docking studies were carried out with the target protein VEGFR-2 to determine the specific binding preferences at the target site. Structure–activity relationship (SAR) was inferred for future optimization based on the performed docking studies.

description: We consider random search processes alternating stochastically between diffusion and ballistic motion, in which the distribution function of ballistic motion directions varies from point to point in space. The specific space dependence of the directional distribution together with the switching rates between the two modes of motion establishes a spatially inhomogeneous search strategy. We show that the mean first passage times for several standard search problems - narrow escape, reaction partner finding, reaction-escape - can be minimized with a directional distribution that is reminiscent of the spatial organization of the cytoskeleton filaments of cells with a centrosome: radial ballistic transport from center to periphery and back, and ballistic transport in random directions within a concentric shell of thickness $Δ_{\rm opt}$ along the domain boundary. The results suggest that living cells realize efficient search strategies for various intracellular transport problems economically through a spatial cytoskeleton organization that involves radial microtubules in the central region and only a narrow actin cortex rather than a cell body filled with randomly oriented actin filaments.

description: This work is focused on the study of the nonlinear elliptic higher order equation \begin{equation}\nonumber \left( -Δ\right)^m u = S_k[-u] + λf, \qquad x \in \mathbb{R}^N, \end{equation} where the $k-$Hessian $S_k[u]$ is the $k^{\mathrm{th}}$ elementary symmetric polynomial of eigenvalues of the Hessian matrix of the solution and the datum $f$ belongs to a suitable functional space. This problem is posed in $\mathbb{R}^N$ and we prove the existence of at least one solution by means of topological fixed point methods for suitable values of $m \in \mathbb{N}$. Questions related to the regularity of the solutions and extensions of these results to the nonlocal setting are also addressed. On the way to construct these proofs, some technical results such as a fixed point theorem and a refinement of the critical Sobolev embedding, which could be of independent interest, are introduced.

description: The concentrations of the 16 US EPA polycylic aromatic hydrocarbons (PAHs) were investigated in oil and tomato-based sauces from some popular brands of canned fish products (mackerel, sardine and tuna) commonly consumed in Nigeria. The aim of the study was to provide data on the PAH compositions and likely risks arising from ingestion of these oil and tomato-based sauces. The PAH content in these oils and sauces was determined by gas chromatography-mass spectrometry. The concentrations of PAHs in these samples varied from 101 to 698 µg kg−1 for tomato sauces from canned mackerel, 168 to 733 µg kg−1 for oils from canned sardines, and 204 to 459 µg kg−1 for oils from canned tuna. The benzo(a)pyrene and PAH4 (benzo(a)anthracene [BaA] + Chrysene [Chry] + benzo(a)pyrene [BaP] + benzo(b)fluoranthene [BbF]) concentrations in the majority of the samples exceeded their respective limits as specified by the European Union regulations. The benzo(a)pyrene carcinogenic (BaPTEQ) and mutagenic (BaPMEQ) potency values ranged from not detected (nd) to 288 µg kg−1 and nd-217 µg kg−1 respectively. The probable cancer risk arising from consumption of oils and tomato sauces from these canned fish products were above the acceptable risk value of 10−6, which indicates that there is a considerable risk associated with the consumption of sauces and oils from these canned fish products.
