Development of a novel numerical platform for the assessment of atherosclerotic plaque vulnerability
Creators: name: Zareh Bannad Kouki, Mehrdad
Publisher: name: University of British Columbia
Year: 2016

description: It is well known that mechanics of atherosclerotic plaques significantly depend on plaque geometry, location, composition, and loading conditions. Computational studies have shown great potential to characterize this mechanical behavior. Different types of plaque morphologies and mechanical properties have been used in two-dimensional (2D) and three-dimensional (3D) computational platforms mostly based on the finite element method to estimate the stability of rupture-prone plaques and detect their locations. It is well-known that 2D models are not reliable as they do not provide a consistent assessment on the vulnerability of plaques and are highly erroneous. 3D models offer a more effective evaluation but creating 3D models to be further assessed by computational means such as the finite element method is time-consuming. However, 2D models are easier to develop and are less time-consuming to assess. In this thesis, a novel computational platform was developed by which the plaque vulnerability is assessed using only 2D plaque models. We develop idealistic 2D models and their corresponding idealistic 3D models. The idealistic 3D models resemble the worst- and best- case scenarios for each 2D model. Using these 3D idealistic models, a standard error (SE) is estimated and then added to the peak stress values calculated earlier using 2D models. These SEs are also used to assess the probability of plaque stability. In this platform, the effect of viscoelasticity and anisotropy of the plaque composition is taken into consideration and the transmural pressure considered is similar to that of physiological conditions. Also, for the first time heart rate (HR) was introduced as a major predictor of vulnerable plaque ruptures that should be taken into account while mechanics of plaques is studied. A tunable viscoelastic constitutive material model was developed for the fibrous cap tissue in order to calculate the peak cap stress (PCS) in normal physiological conditions while HR changes from 60 bpm to 150 bpm. A critical discussion on stress distribution in the fibrous cap area is made with respect to HR. Results strongly suggest the viscoelastic properties of the fibrous cap tissue and HR together play a major role in the estimation of the PCS values. The results obtained in this thesis may provide a better understanding of the mechanics of atherosclerosis.

description: The recently discovered charmed-strangemeson Ds0*(2317) has been speculated to be a tetraquark mesonium. We study this suggestion with overlap fermions on 2+1 flavor domain wall fermion configurations. We use 4-quark interpolating operatorswith Z4 grid sources on two lattices (16\times16\times16\times32 and 24\times24\times24 times64) to study the volume dependence of the states in an attempt to discern the nature of the states in the four-quark correlator to see if they are all two-meson scattering states or if one is a tetraquark mesonium. We also use the hybrid boundary condition method for this purpose which is designed to lift the two-meson states in energy while leaving the tetraquark mesonium unchanged. We find that the volume method is not effective in the present case due to the fact that the scattering states spectrum is closely packed for such heavy states so that one cannot separate out individual scattering states since the volume dependence is skewed as a result. However, the hybrid boundary condition method works and we found that the four-quark correlators can be fitted with a tower of two-meson scattering states. We conclude that we do not see a tetraquark mesonium in the Ds0*(2317) meson region.

Formation of stars and planets: the role of magnetic fields

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Star formation is thought to be triggered by gravitational collapse of the dense cores of molecular clouds. Angular momentum conservation during the collapse results in the progressive increase of the centrifugal force, which eventually halts the inflow of material and leads to the development of a central mass surrounded by a disc. In the presence of an angular momentum transport mechanism, mass accretion onto the central object proceeds through this disc, and it is believed that this is how stars typically gain most of their mass. However, the mechanisms responsible for this transport of angular momentum are not well understood. Although the gravitational field of a companion star or even gravitational instabilities (particularly in massive discs) may play a role, the most general mechanisms are turbulence viscosity driven by the magnetorotational instability (MRI), and outflows accelerated centrifugally from the surfaces of the disc. Both processes are powered by the action of magnetic fields and are, in turn, likely to strongly affect the structure, dynamics, evolutionary path and planet-forming capabilities of their host discs. The weak ionisation of protostellar discs, however, may prevent the magnetic field from effectively coupling to the gas and shear and driving these processes. Here I examine the viability and properties of these magnetically-driven processes in protostellar discs. The results indicate that, despite the weak ionisation, the magnetic field is able to couple to the gas and shear for fluid conditions thought to be satisfied over a wide range of radii in these discs.

description: Maximally stable component detection is a very popular method for feature analysis in images, mainly due to its low computation cost and high repeatability. With the recent advance of feature-based methods in geometric shape analysis, there is significant interest in finding analogous approaches in the 3D world. In this paper, we formulate a diffusion-geometric framework for stable component detection in non-rigid 3D shapes, which can be used for geometric feature detection and description. A quantitative evaluation of our method on the SHREC'10 feature detection benchmark shows its potential as a source of high-quality features.

description: The Rajang Group sediments in central Borneo form a very thick, deep-water sequence that was deposited in one of the Southeast Asian's largest ancient submarine fans. In Sarawak, the Lupar and Belaga Formations from the Reagan Group, characterized by turbidities and large debris flows, deposited in an interval of at least 30 Ma between the Late Cretaceous (Maastrichtian) and late Middle Eocene. Borneo is one of the few places in SE Asia where sediments of this age are preserved. The Belaga Formation is the oldest and most widespread formation (covers more than 95% area) in the lower Rajang area (Sarawak) and is of Upper Cretaceous to Upper Eocene age. The Belaga Formation is believed to reach great thickness between 10 km and 15 km, even allowing for repetitive sequences through folding and thrusting. Numerous researchers had tried to study the Rajang Group and Belaga Formation. Stratigraphy of both these interrelated units is still not much clear. The purpose of this study is to report about the various divisions that have been proposed for both of these geological mysteries in Sarawak, with a special emphasis on the occurrence of different sedimentological facies in Belaga Formation. “Belaga deep marine fan” or “Belaga system” in ancient “Rajang Basin” might have received deep marine sediment in three possible phases, i.e. (i) Late Cretaceous – Early Eocene, (ii) Early Eocene – Middle Eocene, and (iii) Middle Eocene – Late Eocene. The new finding suggests that each member of this formation consists of at least five major types of deep-marine sedimentary facies i.e (1) Thick sandstone facies, (2) Interbed sand silt facies, (3) Heterolithic facies, (4) Slump facies, and (5) Black shale facies.

description: Diversity-multiplexing tradeoff (DMT) was characterized asymptotically (SNR-> infinity) for i.i.d. Rayleigh fading channel by Zheng and Tse [1]. The SNR-asymptotic DMT overestimates the finite-SNR one [2]. This paper outlines a number of additional limitations and difficulties of the DMT framework and discusses their implications. Using the recent results on the size-asymptotic (in the number of antennas) outage capacity distribution, the finite-SNR, size-asymptotic DMT is derived for a broad class of fading distributions. The SNR range over which the finite-SNR DMT is accurately approximated by the SNR-asymptotic one is characterized. The multiplexing gain definition is shown to affect critically this range and thus should be carefully selected, so that the SNR-asymptotic DMT is an accurate approximation at realistic SNR values and thus has operational significance to be used as a design criteria. The finite SNR diversity gain is shown to decrease with correlation and power imbalance in a broad class of fading channels, and such an effect is described in a compact, closed form. Complete characterization of the outage probability (or outage capacity) requires not only the finite-SNR DMT, but also the SNR offset, which is introduced and investigated as well. This offset, which is not accounted for in the DMT framework, is shown to have a significant impact on the outage probability for a broad class of fading channels, especially when the multiplexing gain is small. The analytical results and conclusions are validated via extensive Monte-Carlo simulations. Overall, the size-asymptotic DMT represents a valuable alternative to the SNR-asymptotic one.

description: We report on the full analysis of a Rossi X-ray Timing Explorer (RXTE) Proportional Counter Array (PCA) monitoring of the γ-ray binary system LS I +61 303. The data set covers 42 contiguous cycles of the system orbital motion. Analyzing this X-ray monitoring dataset, the largest to date for this source, we report on the variability of the orbital profile and the spectral distribution, and provide strong evidence for an anti-correlation between flux and spectral index (the higher the flux, the harder the spectral index). Furthermore, we present the analysis of two newly discovered ks-timescale flares, which present significant variability also on shorter timescales, and tend to occur at orbital phases between 0.6-0.9. However, a detailed timing analysis of the flares does not show any coherent or quasi-coherent (QPO) structure in their power spectra. We also investigated the possible appearance of the radio super-orbital modulation at X-rays energies, but we could not unambiguously detect such modulation in the system flux history, nor in the evolution of its orbital modulation fraction.

description: A chromatographic analysis method for determining inorganic anions and melamine in fertilizers was established using ion chromatography (IC). The fertilizer samples were extracted by ultrasonic method with 7 g/L trichloroacetic acid solution and centrifuged. The supernatant is purified by a solid phase extraction column. Then, the anions in the solution were purified using SH-AP-1 (250 mm×4.0 mm) as a separation column, and measured by a suppressed conductivity detector; the melamine in the solution was separated using SH-CC-4 (200 mm×4.0 mm) as a separation column and detected by a UV detector. The results show that the mass concentration of anions had a linear relationship with its peak area within a certain range, the linear correlation coefficient r of the standard curve was greater than 0.999, the recovery rate of spiked samples was 93.4%-104.4%, and the relative standard deviation (RSD) of the measured value (n = 6) was less than 4%. Thus, this method is widely suitable for detection of anions and cations in a variety of fertilizer samples.
The role of solvation in proton transfer reactions: implications for predicting salt/co-crystal formation using the ΔpKa rule

description: The ΔpKa rule is commonly applied by chemists and crystal engineers as a guideline for the rational design of molecular salts and co-crystals. For multi-component crystals containing acid and base constituents, empirical evidence has shown that ΔpKa > 4 almost always leads to salts, ΔpKa < −1 almost always leads to co-crystals and ΔpKa between −1 and 4 can be either. This paper reviews the theoretical background of the ΔpKa rule and highlights the crucial role of solvation in determining the outcome of the potential proton transfer from acid to base. New data on the frequency of the occurrence of co-crystals and salts in multi-component crystal structures containing acid and base constituents show that the relationship between ΔpKa and the frequency of salt/co-crystal formation is influenced by the composition of the crystal. For unsolvated co-crystals/salts, containing only the principal acid and base components, the point of 50% probability for salt/co-crystal formation occurs at ΔpKa ≈ 1.4, while for hydrates of co-crystals and salts, this point is shifted to ΔpKa ≈ −0.5. For acid–base crystals with the possibility for two proton transfers, the overall frequency of occurrence of any salt (monovalent or divalent) versus a co-crystal is comparable to that of the whole data set, but the point of 50% probability for observing a monovalent salt vs. a divalent salt lies at ΔpKa,II ≈ −4.5. Hence, where two proton transfers are possible, the balance is between co-crystals and divalent salts, with monovalent salts being far less common. Finally, the overall role played by the “crystal” solvation is illustrated by the fact that acid–base complexes in the intermediate region of ΔpKa tip towards salt formation if ancillary hydrogen bonds can exist. Thus, the solvation strength of the lattice plays a key role in the stabilisation of the ions.
Different eyes, ears, and bodies : pianist Nobuyuki Tsujii and the education of the sensorium through musical performance
Creators: name: Honisch, Stefan Sunandan
Publisher: name: University of British Columbia
Year: 2016

description: My dissertation explores the educative possibilities and limits of musical performance as a medium through which musicians and audiences reimagine sensory, affective, bodily, and cognitive experiences of music. The dissertation's focal point is a 2013 recital at the University of British Columbia by pianist Nobuyuki Tsujii, as part of Beyond the Screen: disAbility and the Arts, a series that raised questions about the reception of musicians with disabilities, the inclusion of disabled bodies in music pedagogy, and the meritocratic ethos that underpins competitive practices in music, education, and society. The polemical reception of Tsujii's shared gold medal with Haochen Zhang at the 2009 Van Cliburn International Piano Competition in Fort Worth, Texas serves as the larger context for the present study. Speculation as to the role that Tsujii's blindness played in his favorable evaluation by the competition jury (Ivry, 2009) was countered by denial of any such influence (Kaplinsky, quoted in Wise, 2009), throwing into sharp relief a profound discomfort among musicians, critics and the general public with the disabled body in music. Tsujii himself declared shortly after the competition that he would like to be received as "simply a pianist" (Oda, 2009, para. 6) and has continued to resist the category of "blind pianist" (Ikenberg, 2014b, para. 8). Interviews with Tsujii and a purposive sample of eleven individual audience members following his 2013 UBC recital, combined with textual analysis of newspapers, magazines, and films documenting the pianist's career since 2009 locate Tsujii's reception in an educative gap between performer and audience, akin to that between teacher and student, a philosophical stance which emphasizes education as an interaction between the one who teaches and the one who learns (Biesta, 2004, p. 13). Showing how different levels of familiarity with the conventions of musical performance lead performers, critics, and audiences to interact with Tsujii as pianist and blind pianist in multiple and sometimes contradictory ways, this dissertation contributes to scholarship on the aesthetic and pedagogical significance of "person-first" versus "disability-first" language, the educative capacities of musical performance, and on the place of disabled bodies in music pedagogy.

description: We derive the quantum Teichmüller space, previously constructed by Kashaev and by Fock and Chekhov, from tensor products of a single canonical representation of the modular double of the quantum plane. We show that the quantum dilogarithm function appears naturally in the decomposition of the tensor square, the quantum mutation operator arises from the tensor cube, the pentagon identity from the tensor fourth power of the canonical representation, and an operator of order three from isomorphisms between canonical representation and its left and right duals. We also show that the quantum universal Teichmüller space is realized in the infinite tensor power of the canonical representation naturally indexed by rational numbers including the infinity. This suggests a relation to the same index set in the classification of projective modules over the quantum torus, the unitary counterpart of the quantum plane, and points to a new quantization of the universal Teichmüller space.

Investigating the protein-protein interactions between TAR DNA-binding protein 43 AND p65 subunit of NF-κB
Creators: name: Lee, Joseph
Publisher: name: University of British Columbia
Year: 2016

description: TAR DNA-binding Protein 43 (TDP-43), a ubiquitous protein that regulates gene expression, has been found to play a crucial role in the pathogenesis of Amyotrophic Lateral Sclerosis (ALS), in which the disease is characterized by TDP-43 protein inclusion bodies. Relevant literature suggests that the protein either self-aggregates or interacts with various partners to cause this proteinopathy. One of these binding partners was suggested to be the p65 domain of the nuclear factor kappa-B (NF-κB), a transcription protein complex which plays a crucial role in inflammatory and immune responses. It is upon this hypothetical disease pathogenesis that the study of TDP-43 and NF-κB p65 is rationalized. Hence, the first part of the thesis describes the methods that were developed to obtain pure recombinant TDP-43 from an E.coli expression system. Subsequently, the preparation of NF-κB p65 peptides using solid phase peptide synthesis (SPSS) is described in the thesis. Furthermore, the structural conformation of proteins and peptides was explored using molecular dynamics (MD) simulations to predict how they will behave in vivo and also to allow a comparison to in vitro experimentation.

description: We present new deep and accurate space (Advanced Camera for Surveys -- Wide Field Planetary Camera 2 at the Hubble Space Telescope) and ground-based (Suprime-Cam at Subaru Telescope, Mega-Cam at Canada-France-Hawaii Telescope) photometric and astrometric data for the Local Group dwarf irregular IC10. We confirm the significant decrease of the young stellar population when moving from the center toward the outermost regions. We find that the tidal radius of IC10 is significantly larger than previous estimates of $r_t \lesssim$ 10\min. By using the $I$,\vmi\ Color Magnitude Diagram based on the Suprime-Cam data we detect sizable samples of red giant (RG) stars up to radial distances of 18-23$'$ from the galactic center. The ratio between observed star counts (Mega-Cam data) across the tip of the RG branch and star counts predicted by Galactic models indicate a star count excess at least at a 3$σ$ level up to 34-42\min\ from the center. This finding supports the hypothesis that the huge H{\size{I}} cloud covering more than one degree across the galaxy is associated with IC10 \citep{huchtmeier79,cohen79}. We also provide new estimates of the total luminosity ($L_V\sim9\times$$10^7$ $L_\odot$, $M_V$$\sim$-15.1 mag) that agrees with similar estimates available in the literature. If we restrict to the regions where rotational velocity measurements are available (r$\approx13'$), we find a mass-to-light ratio ($\sim$10 $M_\odot$ $L_\odot$) that is at least one order of magnitude larger than previous estimates. The new estimate should be cautiously treated, since it is based on a minimal fraction of the body of the galaxy.

description: In this paper we study some aspects of search for an immobile target by a swarm of N non-communicating, randomly moving searchers (numbered by the index k, k = 1, 2,..., N), which all start their random motion simultaneously at the same point in space. For each realization of the search process, we record the unordered set of time moments \{τ_k\}, where τ_k is the time of the first passage of the k-th searcher to the location of the target. Clearly, τ_k's are independent, identically distributed random variables with the same distribution function Ψ(τ). We evaluate then the distribution P(ω) of the random variable ω\sim τ_1/barτ, where barτ = N^{-1} \sum_{k=1}^N τ_k is the ensemble-averaged realization-dependent first passage time. We show that P(ω) exhibits quite a non-trivial and sometimes a counterintuitive behaviour. We demonstrate that in some well-studied cases e.g., Brownian motion in finite d-dimensional domains) the \textit{mean} first passage time is not a robust measure of the search efficiency, despite the fact that Ψ(τ) has moments of arbitrary order. This implies, in particular, that even in this simplest case (not saying about complex systems and/or anomalous diffusion) first passage data extracted from a single particle tracking should be regarded with an appropriate caution because of the significant sample-to-sample fluctuations.

description: Introduction  The commonest type of cancer in head and neck region is oral squamous cell carcinoma due to its high rates of occurrence and mortality, Cluster of differentiation 44 (CD44) is a surface glycoprotein present on tumor cell. It regulates cell proliferation, adhesion, migration an invasion of cancer stem cell. Immunoexpression of CD44 in surgical margins indicates poor prognosis of disease and increased risk of local recurrence.[4] Objectives To evaluate and correlate CD44 immunoexpression in tumor tissue and surgical margins of oral squamous cell carcinoma with 3 years survival. Methodology All tissue sections will be proceed for CD44 Immunohistochemistry. After that light microscopic evaluation of CD44 expression will be done. Dark brown color of membranous staining of neoplastic cells will be evaluated for CD44 positivity which have to be observed in tumor core, basal layer because most of stem cells are present in basal layer of oral mucosa and in invasive front of tumor. Expected results  The present study will find the immunohistochemical expression of CD44 tumor tissue and surgical margins of OSCC, in order to evaluate the prognosis of OSCC. Immunoexpression may vary in according to their different grades. Conclusion We hypothesized that, as the disease stage advances, intensity of CD44 expression immunohistochemically may increases and it can affect overall survival adversely, hence it is considered as an independent predictor of prognosis of OSCC. Keywords* CD44, CSCs, Oral squamous cell carcinoma, surgical margins of OSCC, Immunohistochemistry.

description: Introduction  Commonest type of malignancy in the head & neck region is Oral Squamous Cell Carcinoma. Brandwein provided a risk model that includes scores for the following three factors: worst invasion pattern, lymphocytic host response and perineural invasion. This risk model accounts for overall survival and local recurrence. p53 is considered to be one of the most significant prognostic marker[2]. Objectives To Assess & Correlate Brandwein Gensler criteria with p53 immunoexpression in Oral Squamous cell carcinoma. Methodology In this study, total 80 samples will be included. Histopathologically diagnosed OSCC patients will be taken for the study. H & E stained slides of all cases will be evaluated using Brandwein Gensler criteria and then immunostaning will be done for p53 immunoexpression. The correlation of Brandwein Gensler criteria and p53 immunoexpression will be carried out. Expected results  The present study will find out the assessment & correlation of Brandwein Gensler criteria with p53 immunoexpression. As the Brandwein Gensler criteria score will increase, intensity of p53 immunoexpression will also increase. Conclusion We hypothesize that, Brandwein Gensler criteria may be significantly assessed & correlated with p53 immunoexpression in OSCC. As the Brandwein Gensler criteria score increases, intensity of p53 immunoexpression may also increase in OSCC.

description: We analyse observed fractions of core-collapse SN types from the Lick Observatory SN Search, and we discuss corresponding implications for massive star evolution. For a standard IMF, observed fractions of SN types cannot be reconciled with expectations of single-star evolution. The mass range of WR stars that shed their H envelopes via their own mass loss accounts for less than half the observed fraction of SNeIbc. Progenitors of SNeIbc must extend to a much lower range of initial masses than classical WR stars, and we argue that most SNIbc and SNIIb progenitors must arise from binary Roche-lobe overflow. SNeIc still trace higher mass and metallicity, because line-driven winds in the WR stage remove the He layer and propel the transition from SNIb to Ic. Less massive progenitors of SNeIb and IIb may not be classical WR stars; they may be underluminous with weak winds, possibly hidden by overluminous mass-gainer companions that appear as B[e] supergiants or related objects having aspherical circumstellar material. The remaining SN types (II-P, II-L, and IIn) are redistributed across the full range of initial mass. We consider direct collapse to black holes without visible SNe, but find this problematic. Major areas of remaining uncertainty are (1) the influence of binary separation, rotation, and metallicity, (2) mass differences in progenitors of SNeIIn compared to SNeII-L and II-P, and (3) SNeIc arising from single stars with eruptive mass loss, its dependence on metallicity, and how it relates to diversity within the SNIc subclass.

Functional characterization and spatial and temporal patterns of expression of genes involved in gibberellin and diterpene resin acid biosynthesis in white spruce
Creators: name: Storey, Kathryn Madeleine

description: Conifers produce large quantities of diterpene resin acids (DRAs) as major components of the constitutive and induced oleoresin defense system. Like all vascular plants, conifers also produce gibberellin (GA) diterpene phytohormones, which influence growth and development. Conifers thus provide an interesting biological system for comparing the GA and DRA diterpene biosynthetic pathways. Despite serving different functions in growth and defense, respectively, the GA and DRA biosynthetic pathways are biochemically similar, utilizing the same isoprenoid precursors, evolutionarily related diterpene synthases (diTPSs), and functionally similar cytochrome P450 monooxygenases (CYP450s) to produce structurally similar diterpene intermediates and diterpene acid products. Functional characterization of central diTPS genes (ent-copalyl diphosphate synthase [CPS], ent-kaurene synthase [KS], levopimaradiene/abietadiene synthase [LAS]) and CYP450 genes (ent-kaurene oxidase [CYP701] and CYP720B4) in white spruce (Picea glauca), described in this thesis, allowed for comparative analysis of GA and DRA pathway genes. This thesis characterized the DXS (1-deoxy-D-xylulose 5-phosphate synthase) gene family in white spruce as additional analysis of the isoprenoid biosynthetic pathway producing the common precursor to both GAs and DRAs. Transcript expression of genes was analyzed to understand their seasonal (year-long time course of apical bud and shoot development), sample-specific (e.g. needle, stem, bud, bark/phloem, wood/xylem), and stress-specific (methyl jasmonate [MeJA] exposure) spatial and temporal patterns. Functionality of the DRA pathway was also assessed via quantification of DRA products. Expression of DRA and GA pathway genes was generally spatially separated. Expression of DRA genes was low in photosynthetic tissues but up-regulated during the time of year when trees are most likely to encounter seasonal attack from insect pests; expression declined sharply well before dormancy showing a strong seasonality to DRA production. GA related genes had broader expression across sample types and throughout the year, but spatially were mainly allocated to photosynthetic tissues. GA and DRA pathway genes all showed differential responses to MeJA treatment, and within corresponding sample types, age also played a role in expression. These studies improve our understanding of the organization of conifer chemical defenses, showing distinct differences compared with GA gene expression, and providing information on the spatial, seasonal and stress-responsive expression of DRA pathway genes.

description: We calculate the diffusion coefficients of persistent random walks on cubic and hypercubic lattices, where the direction of a walker at a given step depends on the memory of one or two previous steps. These results are then applied to study a billiard model, namely a three-dimensional periodic Lorentz gas. The geometry of the model is studied in order to find the regimes in which it exhibits normal diffusion. In this regime, we calculate numerically the transition probabilities between cells to compare the persistent random-walk approximation with simulation results for the diffusion coefficient.

description: Aims: Integral Field Spectroscopy (IFS) is a powerful approach for the study of nearby galaxies since it enables a detailed analysis of their resolved physical properties. Here we present the sample of nearby galaxies selected to exploit the two dimensional information provided by the IFS. Methods: We observed a sample of 48 galaxies from the Local Universe with the PPAK Integral Field Spectroscopy unit (IFU), of the PMAS spectrograph, mounted at the 3.5m telescope at Calar Alto Observatory (Almeria, Spain). Two different setups were used during these studies (low -V300- and medium -V600- resolution mode) covering a spectral range of around 3700-7000 Angs. We developed a full automatic pipeline for the data reduction, that includes an analysis of the quality of the final data products. We applied a decoupling method to obtain the ionised gas and stellar content of these galaxies, and to derive the main physical properties of the galaxies. To asses the accuracy in the measurements of the different parameters, we performed a set of simulations to derive the expected relative errors obtained with these data. In addition, we extracted two aperture, central and integrated spectra, from the datacubes. The main properties of the stellar populations and ionised gas of these galaxies and an estimate of their relative errors are derived from those spectra, as well as from the whole datacubes. Results: The comparison of the central spectrum extracted from the datacubes and the SDSS spectrum for those galaxies in common shows a good agreement between the derived values from both samples. We find differences in the properties of galaxies when comparing a central and an integrated spectra, showing the effects of the extracted aperture in the interpretation of the data. Finally, we present two dimensional maps of some of the main properties derived with the decoupling procedure.
