Ως εκ τούτου, επιλέχθηκε η συστηματοποιημένη ανάλυση του Συντονιστικού Κανονισμού και η σκιαγράφηση των αλλαγών που έχουν επέλθει υπό το καθεστώς του νέου Συντονιστικού Κανονισμού 883/04, σε αντιπαραβολή με τον προηγούμενο (παλαιό Κανονισμό 1408/71), προκειμένου να αποτυπώσουμε την παρεχόμενη προστασία, τα τυχόν υφιστάμενα κενά και την εφαρμογή του Κανονισμού εν γένει και ειδικότερα σε σχέση με τις συντάξεις. Εκκινούμε από τις γενικές διατάξεις (Τίτλος Ι) και εν συνεχεία εξετάζουμε τους κανόνες προσδιορισμού της εφαρμοστέας νομοθεσίας (Τίτλος ΙΙ), προκειμένου να υπεισέλθουμε στην κριτική παρουσίαση όλων των ειδικών διατάξεων που αφορούν τις συντάξεις και τους συνταξιούχους (Τίτλος ΙΙΙ). Τα πολυποίκιλα ζητήματα που προκύπτουν από την εφαρμογή του Κανονισμού αναλύονται σε βάθος. Η παρουσίαση των κανόνων συντονισμού μέσα από την αναπόφευκτη σύγκριση μεταξύ του παλαιού και του νέου Κανονισμού εμπλουτίζεται από τη σχετική αρθρογραφία και βιβλιογραφία, τη νομολογία του Δικαστηρίου της ΕΕ, σχετικές πράξεις των ευρωπαϊκών οργάνων, αλλά και τις αποφάσεις της Διοικητικής Επιτροπής για το Συντονισμό των Συστημάτων Κοινωνικής Ασφάλειας
description: The aim of the thesis was the presentation and study of the Coordinating Regulation focusing on pension protection. Therefore, the systematic analysis of the Coordinating Regulation and the outline of the changes that have occurred in the new Coordination Regulation 883/04, in comparison with the previous (old Regulation 1408/71) took place in order to capture the social protection provided, any existing gaps, as well as the application of the coordination rules in general and particularly in relation to pensions. Having the general provisions (Title I) as a starting point, the rules for determining the applicable legislation (Title II) are the next to be examined, and then all the special provisions relating to pensions and pensioners (Title III) are illustrated on a critical basis. The multifarious issues arising from the application of Coordination Regulation are analyzed in depth. The presentation of the coordination rules through the inevitable comparison between the old and the new regulation is enriched by the relevant literature, the case law of the Court of EU, studies of the European institutions, and the Administrative Commission’s decisions for the Coordination of Social Security Systems.

description: We conjecture that because of color confinement, the physical vacuum forms an event horizon for quarks and gluons which can be crossed only by quantum tunneling, i.e., through the QCD counterpart of Hawking radiation by black holes. Since such radiation cannot transmit information to the outside, it must be thermal, of a temperature determined by the chromodynamic force at the confinement surface, and it must maintain color neutrality. We explore the possibility that the resulting process provides a common mechanism for thermal hadron production in high energy interactions, from $e^+e^-$ annihilation to heavy ion collisions.

description: In India, traditional herbal medicines have been an essential part of therapy for the last centuries. However, a large portion of the general populace is using these therapies in combination with allopathy lacking a proper understanding of possible interactions (synergistic or antagonistic) between the herbal product and the allopathic drug. This is based on the assumption that herbal drugs are relatively safe, i.e. without side effects. We have established a comprehensive understanding of the possible herb–drug interactions and identified interaction patterns between the most common herbs and drugs currently in use in the Indian market. For this purpose, we listed common interactors (herbs and allopathic drugs) using available scientific literature. Drugs were then categorized into therapeutic classes and aligned to produce a recognizable pattern present only if interactions were observed between a drug class and herb in the scientific literature. Interestingly, the top three categories (with highest interactors), antibiotics, oral hypoglycemics, and anticonvulsants, displayed synergistic interactions only. Another major interactor category was CYP450 enzymes, a natural component of our metabolism. Both activation and inhibition of CYP450 enzymes were observed. As many allopathic drugs are known CYP substrates, inhibitors or inducers, ingestion of an interacting herb could result in interaction with the co-administered drug. This information is largely unavailable for the Indian population and should be studied in greater detail to avoid such interactions. Although this information is not absolute, the systematic literature review proves the existence of herb–drug interactions in the literature and studies where no interaction was detected are equally important.
Bis(hydrocarbyl) and alkylidene complexes of iridium
Creators: name: Massey, Roberta Lynn
Publisher: name: University of British Columbia

description: The iridium(m) bis(hydrocarbyl) complexes Ir(R)R'[N(SiMe₂CH₂PPh₂)₂] for R = CH₃, C₆H₅, CH₂Ph, and R' = CH₃, C₆H₅, CH₂Ph, CH₂CMe₃, CH₂SiMe₃ were synthesized in high yields from the hydrocarbyl halide precursors Ir(R)X [N(SiMe₂CH₂PPh₂)₂], where X = I or Br, by reaction with the appropriate organolithium salt LiR’. The geometry of the five-coordinate complexes was determined to be trigonal bipyramidal both in solution, on the basis of NOEDIFF experiments, and in the solid state by comparison to the previously determined X-ray structures of the methyl neopentyl and dibenzyl derivatives. The complexes were found to be thermally stable, however, they did react when exposed to sunlight to give the alkylidene complexes Ir(=CHR)[N(SiMe₂CH₂PPh₂)₂] for R = H, Ph. Although the benzylidene complex (R = Ph) has not yet been isolated in the pure state, the =CHPh ligand was found to be rotating about the Ir=C bond axis on the ¹H NMR time scale with a ΔG‡[sub rot] = 9.3 kcal/mol. The reactivity of the methylidene complex (R = H) was also briefly explored with CH₃I, C₂H₄, C₂H₂, CO, PMe₃, and H₂. On the basis of the observed spectroscopic data, several of these reactions involve carbon-carbon bond formation, and the methylidene carbon appears to be nucleophilic in nature.
A unified projection formalism for the Al-Pd-Mn quasicrystal Xi-approximants and their metadislocations

description: The approximants xi, xi' and xi'_n of the quasicrystal Al-Mn-Pd display most interesting plastic properties as for example phason-induced deformation processes (Klein, H., Audier, M., Boudard, M., de Boissieu, M., Beraha, L., and Duneau, M., 1996, Phil. Mag. A, 73, 309.) or metadislocations (Klein, H., Feuerbacher, M., Schall, P., and Urban, K., 1999, Phys. Rev. Lett., 82, 3468.). Here we demonstrate that the phases and their deformed or defected states can be described by a simple projection formalism in three-dimensional space - not as usual in four to six dimensions. With the method we can interpret microstructures observed with electron microscopy as phasonic phase boundaries. Furthermore we determine the metadislocations of lowest energy and relate them uniquely to experimentally observed ones. Since moving metadislocations in the xi'-phase can create new phason-planes, we suggest a dislocation induced phase transition from xi' to xi'_n. The methods developed in this paper can as well be used for various other complex metallic alloys.

description: Abuse of new psychoactive substances is an emerging social problem. Several phenethylamines are internationally controlled substances as they are likely to be abused and have adverse effects. Phenethylamine analog 2-(4-iodo-2,5-dimethoxyphenyl)-N-(2-methoxybenzyl)ethanamine (25I-NBOMe) has been reported as one of the most commonly abused psychoactive substance. However, the cardiotoxicity of this compound has not been extensively evaluated. Thus, in this study, we investigated the adverse cardiovascular effects of 25I-NBOMe, related to p21 (CDC42/RAC)-activated kinase 1 (PAK1). The cardiotoxicity of 25I-NBOMe was evaluated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, live/dead cytotoxicity assay, PAK1/CDC42 kinase assay, and in vivo electrocardiography (ECG). Also, we analyzed the expression level of PAK1, which is known to play key roles in the cardiovascular system. In the MTT assay, cell viability of 25I-NBOMe-treated H9c2 cells or primary cardiomyocytes of ICR mice decreased in a concentration-dependent manner. Results from the in vitro cytotoxicity assay in cardiomyocytes showed that 25I-NBOMe decreased the viability of H9c2 rat cardiomyocytes, and TC50 of 25I-NBOMe was found to be 70.4 μM. We also observed that 25I-NBOMe reduced PAK1 activity in vitro. Surface ECG measurement revealed that intravenous injection of 25I-NBOMe (doses of 1.0 and 3.0 mg/kg, corresponding to serum concentrations of 18.1 and 28.6 ng/mL, respectively) prolonged the QTc interval in SD rats. Furthermore, treatment with 25I-NBOMe downregulated the expression of PAK1 in the hearts of SD rats and H9c2 cells. In summary, our findings indicate that PAK1-related adverse effects of 25I-NBOMe can cause toxicity to cardiomyocytes and induce an abnormal ECG pattern in animals.
Two-Frequency Radiative Transfer. II: Maxwell Equations in Random Dielectrics

description: The paper addresses the space-frequency correlations of electromagnetic waves in general random, bi-anisotropic media whose constitutive tensors are complex Hermitian matrices. The two-frequency Wigner distribution (2f-WD) for polarized waves is introduced to describe the space-frequency correlations and the closed form Wigner-Moyal equation is derived from the Maxwell equations. Two-frequency radiative transfer (2f-RT) equations is then derived from the Wigner-Moyal equation by using the multiple scale expansion. For the simplest isotropic medium, the result coincides with Chandrasekhar's transfer equation. In birefringent media, the 2f-RT equations take the scalar form due to the absence of depolarization. A number of birefringent media such as the chiral, uniaxial and gyrotropic media are examined. For the unpolarized wave in the isotropic medium the 2f-RT equations reduces to the Fokker-Planck equation previously derived in Part I. A similar Fokker-Planck equation is derived from the scalar 2f-RT equation for the birefringent media.

Leed studies on two surfaces of copper
Creators: name: Parkin, Sean Richard
Publisher: name: University of British Columbia
Year: 2010

description: The work presented in this thesis includes investigations using low energy electron diffraction (LEED) of the clean stepped Cu(311) surface and its interactions with sulphur, and also for a half monolayer oxygen superstructure on Cu(110) designated Cu(110)-(2x1)-O. In each case, intensity versus energy (1(E)) curves were measured with a video LEED analyzer for sets of independent diffracted beams for future comparison to the results of multiple scattering calculations. The clean Cu(311) surface was cut and polished from a single crystal copper rod and cleaned by sputter-etching with argon ions followed by annealing. Intensity measurements were recorded for 14 symmetry inequivalent diffraction beams at normal incidence, followed by six at 10° off normal incidence. Adsorption of sulphur on the Cu(311) surface was carried out by dosing with H₂S followed by its presumed dissociation and loss of hydrogen to the vacuum. This study indicated that S atoms order themselves on Cu(311) only in the [Oil] direction. In addition to experimental work on the Cu(311) surface, a discussion is made of the difficulties associated with the application of LEED to adsorption on stepped surfaces. The Cu(110)-(2x1)-O stucture was prepared by the adsorption of oxygen on the (110) surface of copper. The conditions necessary to produce the best LEED pattern were found by analysis of adsorption spot profiles, and experimental LEED 1(E) curves were recorded for nine independent beams at normal incidence and a further six at 10° off normal incidence.

description: Our previous study showed that datumetine modulates NMDAR activity with long term exposure leading to memory deficit and altered NMDAR signaling. We aim to explore the neurotransmitters perturbations of acute datumetine-NMDAR interaction. Fifteen C57/BL6 mice were used for the study, they are divided into three groups of 5 animals each. Animals were administered DMSO (DMSO/Control), 0.25 mg/kg body weight of datumetine (0.25 Datumetine) and 1 mg/kg bodyweight of datumetine (1.0 Datumetine) intraperitoneally for 14 days. At the end of treatment, animals were euthanized in isofluorane chamber, perfused transcardially with 1XPBS followed by PFA. Immunofluorescence procedure was done to check the distribution of neurons, astrocytes, microglia and major neuronal subtypes in the hippocampus. Expansion and electron microscopy techniques were used to assess the condition of the synapses. Quantitative data were expressed as mean ± SEM and analyzed using ANOVA with Tukey post hoc using p

description: Abridged... Blue stragglers (BSS) are thought to be the product of either primordial or collisional binary systems. In the context of dwarf spheroidal galaxies it is hard to firmly disentangle a genuine BSS population from young main sequence (MS) stars tracing a ~1-2 Gyr old star forming episode. Assuming that their blue plume populations are made of BSS, we estimate the BSS frequency for 8 Local Group non star-forming dwarf galaxies, using a compilation of ground and space based photometry. Our results can be summarized as follows: (i) The BSS frequency in dwarf galaxies, at any given Mv, is always higher than that in globular clusters of similar luminosities; (ii) the BSS frequency for the lowest luminosity dwarf galaxies is in excellent agreement with that observed in the Milky Way halo; and most interestingly (iii) derive a statistically significant anti-correlation between the BSS frequency and the galaxy Mv. The low density, almost collision-less, environments of our dwarf galaxy sample allow us to infer (i) their very low dynamical evolution; (ii) a negligible production of collisional BSS; and consequently (iii) that their blue plumes are mainly made of primordial binaries. The dwarf galaxies anti-correlation can be used as a discriminator: galaxies obeying the anti-correlation are more likely to possess genuine primordial BSS rather than young main sequence stars.

description: Some education researchers have claimed that we should not teach the Bohr model of the atom because it inhibits students' ability to learn the true quantum nature of electrons in atoms. Although the evidence for this claim is weak, many have accepted it. This claim has implications for how to present atoms in classes ranging from elementary school to graduate school. We present results from a study designed to test this claim by developing a curriculum on models of the atom, including the Bohr and Schrodinger models. We examine student descriptions of atoms on final exams in transformed modern physics classes using various versions of this curriculum. We find that if the curriculum does not include sufficient connections between different models, many students still have a Bohr-like view of atoms, rather than a more accurate Schrodinger model. However, with an improved curriculum designed to develop model-building skills and with better integration between different models, it is possible to get most students to describe atoms using the Schrodinger model. In comparing our results with previous research, we find that comparing and contrasting different models is a key feature of a curriculum that helps students move beyond the Bohr model and adopt Schrodinger's view of the atom. We find that understanding the reasons for the development of models is much more difficult for students than understanding the features of the models. We also present interactive computer simulations designed to help students build models of the atom more effectively.

description: In this paper, we find computational formulae for generalized characteristic polynomials of graph bundles. We show that the number of spanning trees in a graph is the partial derivative (at (0,1)) of the generalized characteristic polynomial of the graph. Since the reciprocal of the Bartholdi zeta function of a graph can be derived from the generalized characteristic polynomial of a graph, consequently, the Bartholdi zeta function of a graph bundle can be computed by using our computational formulae.

Quintessential Kination and Leptogenesis

description: Thermal leptogenesis induced by the CP-violating decay of a right-handed neutrino (RHN) is discussed in the background of quintessential kination, i.e., in a cosmological model where the energy density of the early Universe is assumed to be dominated by the kinetic term of a quintessence field during some epoch of its evolution. This assumption may lead to very different observational consequences compared to the case of a standard cosmology where the energy density of the Universe is dominated by radiation. We show that, depending on the choice of the temperature T_r above which kination dominates over radiation, any situation between the strong and the super--weak wash--out regime are equally viable for leptogenesis, even with the RHN Yukawa coupling fixed to provide the observed atmospheric neutrino mass scale ~ 0.05 eV. For M< T_r < M/100, i.e., when kination stops to dominate at a time which is not much later than when leptogenesis takes place, the efficiency of the process, defined as the ratio between the produced lepton asymmetry and the amount of CP violation in the RHN decay, can be larger than in the standard scenario of radiation domination. This possibility is limited to the case when the neutrino mass scale is larger than about 0.01 eV. The super--weak wash--out regime is obtained for T_r << M/100, and includes the case when T_r is close to the nucleosynthesis temperature ~ 1 MeV. Irrespective of T_r, we always find a sufficient window above the electroweak temperature T ~ 100 GeV for the sphaleron transition to thermalize, so that the lepton asymmetry can always be converted to the observed baryon asymmetry.

description: In this manuscript of poems, I seek to address the seeming polarities of sacrifice and excess with respect to the sacred and to show that not only may they co-exist, but that they may actually be viewed as one and the same. With respect to the idea of chaff, the central uniting metaphor of the manuscript, the point I'm working toward is that there actually is no chaff unless everything is chaff--that, in terms of both the inner and outer life, asceticism may have its place, but it should not be looked upon as ''higher" than abundance. The life of the soul is the life of the body, and vice versa; the life of the mind is also the life of the world.

description: We generalize the rotationally-invariant formulation of the slave-boson formalism to multiorbital models, with arbitrary interactions, crystal fields, and multiplet structure. This allows for the study of multiplet effects on the nature of low-energy quasiparticles. Non-diagonal components of the matrix of quasiparticle weights can be calculated within this framework. When combined with cluster extensions of dynamical mean-field theory, this method allows us to address the effects of spatial correlations, such as the generation of the superexchange and the momentum dependence of the quasiparticle weight. We illustrate the method on a two-band Hubbard model, a Hubbard model made of two coupled layers, and a two-dimensional single-band Hubbard model (within a two-site cellular dynamical mean-field approximation).

description: We derive the general continuum model for a bilayer system of staggered-flux square lattices, with arbitrary elastic deformation in each layer. Applying this general continuum model to the case where the two layers are rigidly rotated relative to each other by a small angle, we obtain the band structure of the twisted bilayer staggered-flux square lattice. We show that this band structure exhibits a "magic continuum" in the sense that an exponential reduction of the Dirac velocity and bandwidths occurs in a large parameter regime. We show that the continuum model of the twisted bilayer system effectively describes a massless Dirac fermion in a spatially modulating magnetic field, whose renormalized Dirac velocity can be exactly calculated. We further give an intuitive argument for the emergence of flattened bands near half filling in the magic continuum and provide an estimation of the large number of associated nearly-zero-energy states. We also show that the entire band structure of the twisted bilayer system is free of band gaps due to symmetry constraints.

description: A general class of nonlocal cosmological models is considered. A new method for solving nonlocal Friedmann equations is proposed, and solutions of the Friedmann equations with nonlocal operator are presented. The cosmological properties of these solutions are discussed. Especially indicated is $p$-adic cosmological model in which we have obtained nonsingular bouncing solution and string field theory tachyon model in which we have obtained full solution of nonlocal Friedmann equations with $w=-1$ at large times. The possibility of obtaining realistic value of cosmological constant from nonlocal cosmological models is also discussed.

description: Endophytic fungi are promising sources of bioactive substances; however, their secondary metabolites are toxic to plants, animals, and humans. This study aimed toevaluate the toxic, cytotoxic, mutagenic and oxidant/antioxidant activities of acetonitrile extract (AEPc), citrinin (CIT) and dicitrinin-A (DIC-A) of Penicillium citrinum. For this, the test substances at 0.5; 1.0; 1.5 and 2 μg/mLwere exposed for 24 and 48 h in Artemia salina, and 48 h in Allium cepa test systems. The oxidant/antioxidant test was evaluated in pre-, co- and post-treatment with the stressor hydrogen peroxide (H2O2) in Saccharomyces cerevisiae. The results suggest that the AEPc, CIT and DIC-A at 0.5; 1.0; 1.5 and 2 μg/mL showed toxicity in A. saline, with LC50 (24 h) of 2.03 μg/mL, 1.71 μg/mL and 2.29 μg/mL, and LC50 (48 h) of 0.51 μg/mL, 0.54 μg/mL and 0.54 μg/mL, respectively.In A. cepa, the test substances also exerted cytotoxic and mutagenic effects. The AEPc, CIT and DIC-A at lower concentrations modulated the damage induced by H2O2 in the proficient and mutant strains of S. cerevisiae for cytoplasmic and mitochondrial superoxide dismutase. Moreover, the AEPc at 2 μg/mL and CIT at the two highest concentrations did not affect the H2O2-induced DNA damage in the test strains. In conclusion, AEPc, CIT and DIC-A of P. citrinum may exert their toxic, cytotoxic and mutagenic effects in the test systems possibly through oxidative stress induction pathway.
On the failure of subadditivity of the Wigner-Yanase entropy

description: It was recently shown by Hansen that the Wigner-Yanase entropy is, for general states of quantum systems, not subadditive with respect to decomposition into two subsystems, although this property is known to hold for pure states. We investigate the question whether the weaker property of subadditivity for pure states with respect to decomposition into more than two subsystems holds. This property would have interesting applications in quantum chemistry. We show, however, that it does not hold in general, and provide a counterexample.

description: We investigate the physical property of the kappa parameter and the kappa-distribution in the kappa-deformed statistics, based on Kaniadakis entropy, for a relativistic gas in an electromagnetic field. We derive two relations for the relativistic gas in the framework of kappa-deformed statistics, which describe the physical situation represented by the relativistic kappa-distribution function, provide a reasonable connection between the parameter kappa, the temperature four-gradient and the four-vector potential gradient, and thus present for the case kappa different from zero a clearly physical meaning. It is shown that such a physical situation is a meta-equilibrium state of the system, but has a new physical characteristic.

Pyrazolyl based ligands in transition metal complexes
Creators: name: Olson, Michael David
Publisher: name: University of British Columbia

description: Several uninegative/ multidentate pyrazolyl based ligands were synthesized [eg. HBPZ₃₋, HBpz”₃₋, MeGapz₃₋/ MeGapz” ₃₋, H2BpZ₂₋/ Me2Bpz₂₋/ Me2GapZ₂₋/ Me2Gapz"₂₋/ Me₂Gapz(OCH₂CH₂NH₂)⁻Me₂Gapz(OCH₂CH₂CH=CH₂)⁻ ; pz pyrazolyl/ pz" = 3, 5 dimethylpyrazolyl]. These ligands were reacted with the sterically hindered metal complex, HBpz*₃MCl (M = Co, Ni; pz* = 3-iPr-4-Br-pyrazolyl) and the mixed-ligand transition metal complexes of general formulae, HBpz*₃ML, were isolated. The X-ray crystal structure of one such complex, HBpz*₃Nipz"₃BH was determined showing a near octahedral arrangement of ligands about the nickel centre. The electronic spectra of the nickel complexes were recorded and compared to predicted transitions. The electronic spectra of the four coordinate nickel complex, HBpz*₃NiCl, fit a d⁸, tetrahedral, ligand field model. The six coordinate complexes, HBpz*₃NiL (L = HBPZ₃, HBpz"₃, MeGapz₃, MeGapz”₃), fit a d⁸, octahedral, ligand field model. The unsymmetrical pyrazolylgallate ligands were reacted with the rhodium dimer [Rh(CO)₂CI]₂ to give the square planar complexes, LRh(CO) [L = Me2Gapz(OCH₂CH₂NH₂), Me₂Gapz(OCH₂CH₂CH=CH₂)]. These rhodium[I] complexes appeared to undergo oxidative additions of Mel, allylbromide and I₂. Furthermore these rhodium[I] complexes appeared to bind the small gas molecules, CO and ethene. A number of heterobimetallic complexes, with direct metal-metal bonds, were prepared and isolated from the reaction of the molybdenum anion, HBpz"₃(CO)₃MO⁻ with the transition metal halides, [CuPPb₃Cl]₄, SnR₃Cl (R = Me, Ph) and GePh₃Cl.

description: We report unsuccessful searches for pulsations from the neutron star RX J1836.2+5925 identified with the EGRET source 3EG J1835+5918. A 24 hr observation with the NRAO Green Bank Telescope at 820 MHz placed an upper limit on flux density of 17 uJy for P > 10 ms, and gradually increasing limits for 1 < P < 10 ms. The equivalent luminosity is lower than that of any known pulsar with the possible exception of the radio-quiet gamma-ray pulsar Geminga. A set of observations with the Chandra X-ray Observatory HRC totaling 118 ks revealed no pulsar with 1 ms < P < 10 s. The upper limit on its pulsed fraction is 35% assuming a sinusoidal pulse shape. The position of RX J1836.2+5925 in Chandra observations separated by 3 years is unchanged within errors, leading to an upper limit on its proper motion of <0.14"/yr, or v < 530 km/s at d = 800 pc, a maximum distance estimated from its thermal X-ray spectrum. With these null results, the properties of 3EG J1835+5918 and its X-ray counterpart RX J1836.2+5925 are consistent with a more distant or older version of Geminga, or perhaps a recycled pulsar. Having nearly exhausted the capabilities of current instrumentation at all wavelengths, it will likely fall to the Gamma-ray Large Area Space Telescope to discover pulsations from 3EG J1835+5918.

description: As an alarming group of pollutants, polycyclic aromatic hydrocarbons (PAHs) gather much public health concern not only because of their carcinogenic or co-carcinogenic risk but also by interfering with hormone systems or by causing oxidative damage, henceforth liable to toxic actions on reproduction. Accordingly, the present study was aimed to explore the association between in-utero exposure to PAHs by evaluating their placental levels and infant birth weight among 110 healthy and nonsmoking pregnant women. Placental tissue samples were collected instantly after delivery and were analyzed for the presence of sixteen Environmental Protection Agency (EPA) listed PAHs with the help of Gas chromatography equipped with flame ionization detector (GC-FID). Chrysene and benzo(k)fluoranthene were the predominant PAHs detected in tissue samples. To assess the source of origin of PAHs in placenta tissue samples, the ratio of low molecular weight PAHs to high molecular weight (∑LMW/∑HMW PAHs) was calculated, showing the predominance of pyrogenic sources of PAHs possibly responsible for the exposure of the studied population. Results of regression analysis demonstrated the inverse although not significant association of naphthalene (Nap), acenaphthylene (Acy), anthracene (Anth), pyrene (Pyr), benzo(b)fluoranthene (BbF), benzo(k)Fluoranthene (BkF), benzo(a)pyrene (BaP), indeno (123 cd pyrene (IcdP), dibenzo(ah)anthracene (DahA) and benzo(ghi)Perylene (BghiP) with birth weight of neonates. Additionally, the regression model lay light upon the significant association of fluoranthene (Fla) (coefficient= −1.41 gram, p

description: We construct a new giant graviton solution in AdS_5 x Y_5, with Y_5 a quasi-regular Sasaki-Einstein manifold, consisting on a Kaluza-Klein monopole wrapped around the Y_5 and with its Taub-NUT direction in AdS_5. We find that this configuration has minimal energy when put in the centre of AdS_5, where it behaves as a massless particle. When we take Y_5 to be S^5, we provide a microscopical description in terms of multiple gravitational waves expanding into the fuzzy S^5 defined as an S^1 bundle over the fuzzy CP^2. Finally we provide a possible field theory dual interpretation of the construction.

description: The phase transition of Bose-Einstein condensation is studied in the critical regime, when fluctuations extend far beyond the length scale of thermal de Broglie waves. Using matter-wave interference we measure the correlation length of these critical fluctuations as a function of temperature. The diverging behavior of the correlation length above the critical temperature is observed, from which we determine the critical exponent of the correlation length for a trapped, weakly interacting Bose gas to be $ν=0.67\pm 0.13$. This measurement has direct implications for the understanding of second order phase transitions.
