description: We have studied the sensitivity to variations in the triple alpha and 12C(alpha, gamma)16O reaction rates, of the yield of the neutrino process isotopes 7Li,11B, 19F, 138La, and 180Ta in core collapse supernovae. Compared to solar abundances, less than 15% of 7Li, about 25-80% of 19F, and about half of 138La is produced in these stars. Over a range of two sigma for each helium-burning rate, 11B is overproduced and the yield varies by an amount larger than the variation caused by the effects of neutrino oscillations. The total 11B yield, however, may eventually provide constraints on supernova neutrino spectra.

description: This  study  focused  mainly  on  river  training  and  water  utilization  option  in
Derek  Wuha  Catchment  of  North  Wolo  zone  of  Amhara  National  Regional
State.  In  the  study,  a  GIS  based  semi-distributed  watershed  model  (HEC­
HMS),  HEC-GeoHMS  and  arcHYDRO  softwares  were  used  to  establish
rainfall-runoff  transformations  of  the  ungauged  basin  while  HEC-RAS  was
utilized  for  flood  depth  estimation  and  bank  stability  analysis  input  parameter
generation  in  the  catchments.
From  the  hydrological  analysis  the  peak  discharge  of  the  catchments  was
found  to  be  103 . 7m

catchments.
For  the  discharge  of  103.7m
3
/sec  which  is  obtained  from  hydrology  model,
the  corresponding  flow  depth  was  generated  using  HEC-RAS  and  about
326m  of  the  left  river  channel  [at  nursery  site  starting  at  2872m  from  bridge]
is  incapable  of  safely  passing  the  discharge  without  over  topping .
Furthermore,  the  bridge  near the  outlet  of  the  catchment was  simulated  with
different  flood  magnitudes  and  it  was  observed  that  the  capacity  of  the
bridge  could  not  safely  pass  a 25  year  return  period  discharge.
The  river  bed  and  bank  material  was  tested  in  soil  laboratory  at  Kombolcha
Soil  and  construction  materials  testing  laboratory  to  determine  various
engineering  properties  of  the  soils  and  it  was  found  that  31.6%  of  the  bed
material  is  voids  at  the  subsurface  dam  proposed  site.  Based  on  this  water
holding  capacity  of  the  river  bed  materials,  if  subsurface  barrier  or  dam  is
constructed  across  the  river  with  a  depth  of  8m,  a  water  requirement  of  the
local  residents  can  be  fulfilled  at  least  for  6months  of  the  year  without  any
recharge.
The  river  bank just  downstream  of  bridge  location  was  analyzed  using  Bank
Stability  and  Toe  Erosion  Model  with  the  protection  work  incorporated  and  it
responds to  conditionally stable  safety  factor.
title: DEPRECATED: THE CARDIOTOXICITY OF CARBON MONOXIDE
Creators: name: PATEL, ASHVIN P.
Publisher: name: University of Plymouth
Year: 2003

description: The mechanism(s) responsible for the cardiotoxicity of CO are not clear and do not appear to arise solely from tissue hypoxia. Tissue hypoxia is produced by CO binding to haemoglobin and reducing the amount of oxygen carried by the blood in vivo. CO-induced hypoxia in vivo may be responsible for producing conditions such as those found during ischaemia/reperfusion (l/R) injury. Reactive oxygen species (ROS) produced during l/R injury is established and responsible for cellular/tissue damage from the oxidative damage. We postulate that oxidative stress is responsible for the CO-associated cardiac morbidities found in some cases following severe acute exposure to CO. Isolated perfused rat hearts were used to investigate the physiological and biochemical changes in hearts following CO exposure. Hearts were perfused with buffer equilibrated with different mixtures of CO (0-0.05% CO for 30 minutes) in the presence of 21% oxygen during and after CO exposure (for 90 minutes), i.e. normoxic conditions were used throughout. Some hearts were perfused with water-soluble antioxidants (ascorbic acid and TroloxC) before and during the CO exposure. The reduced heart rate and perfusate flow suggest that CO may have a direct effect in heart tissue. Biochemical measurements suggest that no tissue hypoxia occurred under these conditions. The results provide evidence to suggest that oxidative stress occurred in ventricle tissue after CO exposure and was attenuated by the antioxidants. However, isolated rat liver mitochondria exposed to CO and/or hyperoxia showed no ROS production suggesting that mitochondria may not be a source of the oxidative stress. CO exposure may also produce altered myocardial energetics by oxidatively modifying and/or binding to myoglobin. Tissue damage initiated by CO-induced oxidative stress and hypoxia may potentiate ageing within heart tissue in vivo and could be responsible for producing the observed CO-associated heart morbidity in an MR-like injury.
Magnetic helicity fluxes in interface and flux transport dynamos

description: Dynamos in the Sun and other bodies tend to produce magnetic fields that possess magnetic helicity of opposite sign at large and small scales, respectively. The build-up of magnetic helicity at small scales provides an important saturation mechanism. In order to understand the nature of the solar dynamo we need to understand the details of the saturation mechanism in spherical geometry. In particular, we want to understand the effects of magnetic helicity fluxes from turbulence and meridional circulation. We consider a model with just radial shear confined to a thin layer (tachocline) at the bottom of the convection zone. The kinetic alpha owing to helical turbulence is assumed to be localized in a region above the convection zone. The dynamical quenching formalism is used to describe the build-up of mean magnetic helicity in the model, which results in a magnetic alpha effect that feeds back on the kinetic alpha effect. In some cases we compare with results obtained using a simple algebraic alpha quenching formula. In agreement with earlier findings, the magnetic alpha effect in the dynamical alpha quenching formalism has the opposite sign compared with the kinetic alpha effect and leads to a catastrophic decrease of the saturation field strength with increasing magnetic Reynolds numbers. However, at high latitudes this quenching effect can lead to secondary dynamo waves that propagate poleward due to the opposite sign of alpha. Magnetic helicity fluxes both from turbulent mixing and from meridional circulation alleviate catastrophic quenching.

description: We derive the exact Foldy-Wouthuysen transformation for Dirac fermions in a time independent external electromagnetic field in the basis of the Ritus eigenfunctions, namely the eigenfunctions of the operator $(γ\cdot Π)^2$, with $Π^μ= p^μ- e A^μ$. In this basis, the transformation acquires a free form involving the dynamical quantum numbers induced by the field.

description: The transverse electron scattering response function of 3He was recently studied by us in the quasi-elastic peak region for momentum transfers q between 500 and 700 MeV/c. Those results, obtained using the Active Nucleon Breit frame (ANB), are here supplemented by calculations in the laboratory, Breit and ANB frames using the two-fragment model discussed in our earlier work on the frame dependence of the the longitudinal response function R_L(q,omega). We find relatively frame independent results and good agreement with experiment especially for the lower momentum transfers. This agreement occurs when we neglect an omega-dependent piece of the one-body current relativistic correction. An inclusion of this term leads however to a rather pronounced frame dependence at q=700 MeV/c. A discussion of this term is given here. This report also includes a correction to our previous ANB results for R_T(q,omega).

Density-functional investigation of rhombohedral stacks of graphene: topological surface states, nonlinear dielectric response, and bulk limit

description: A DFT-based investigation of rhombohedral (ABC)-type graphene stacks in finite static electric fields is presented. Electronic band structures and field-induced charge densities are compared with related literature data as well as with own results on (AB) stacks. It is found, that the undoped AB-bilayer has a tiny Fermi line consisting of one electron pocket around the K-point and one hole pocket on the line K-$Γ$. In contrast to (AB) stacks, the breaking of translational symmetry by the surface of finite (ABC) stacks produces a gap in the bulk-like states for slabs up to a yet unknown critical thickness $N^{\rm semimet} \gg 10$, while ideal (ABC) bulk ($β$-graphite) is a semi-metal. Unlike in (AB) stacks, the ground state of (ABC) stacks is shown to be topologically non-trivial in the absence of external electric field. Consequently, surface states crossing the Fermi level must unavoidably exist in the case of (ABC)-type stacking, which is not the case in (AB)-type stacks. These surface states in conjunction with the mentioned gap in the bulk-like states have two major implications. First, electronic transport parallel to the slab is confined to a surface region up to the critical layer number $N^{\rm semimet}$. Related implications are expected for stacking domain walls and grain boundaries. Second, the electronic properties of (ABC) stacks are highly tunable by an external electric field. In particular, the dielectric response is found to be strongly nonlinear and can e.g. be used to discriminate slabs with different layer numbers. Thus, (ABC) stacks rather than (AB) stacks with more than two layers should be of potential interest for applications relying on the tunability by an electric field.

description: An algebraic Riccati equation for linear operators is studied, which arises in systems theory. For the case that all involved operators are unbounded, the existence of infinitely many selfadjoint solutions is shown. To this end, invariant graph subspaces of the associated Hamiltonian operator matrix are constructed by means of a Riesz basis with parentheses of generalised eigenvectors and two indefinite inner products. Under additional assumptions, the existence and a representation of all bounded solutions is obtained. The theory is applied to Riccati equations of differential operators.

description: The subject of graduate work is search of integral characteristics of exhaust hood.
The goal of the work is to compare integral characteristics of by results of computation results with different border conditions. To achieve the goal, itâs necessary to carry out numerical computations of last turbine stage, exhaust hood with different border conditions in exhaust hood inlet.
The relevance of this work lies in the fact that the LP exhaust system of steam turbine is an object the improvement of which can lead to a significant increase in the efficiency of the steam turbine. Comparison of results and processes of numerical calculations gives an understanding in the choice of a more operationally simple and effective method fluid dynamic calculations

description: We have performed an angle-resolved photoemission spectroscopy study of a new iron-based superconductor Sr4V2O6Fe2As2. While V 3d orbitals are found to be in a Mott insulator state and show an incoherent peak at ~ 1 eV below the Fermi level, the dispersive Fe 3d bands form several hole- and electron-like Fermi surfaces (FSs), some of which are quasi-nested by the (pi, 0) wave vector. This differs from the local density approximation (LDA) calculations, which predict non-nested FSs for this material. However, LDA+U with a large effective Hubbard energy U on V 3d electrons can reproduce the experimental observation reasonably well. The observed fermiology in superconducting Sr4V2O6Fe2As2 strongly supports that (pi, 0) interband scattering between quasi-nested FSs is indispensable to superconductivity in pnictides.

Efficient assembly of large genomes

description: Genome sequence assembly presents a fascinating and frequently-changing challenge. As DNA sequencing technologies evolve, the bioinformatics methods used to assemble sequencing data must evolve along with it. Sequencing technology has evolved from slab gel sequencing, to capillary sequencing, to short read sequencing by synthesis, to long-read and linked-read single-molecule sequencing. Each evolutionary jump in sequencing technology required developing new bioinformatic tools to address the unique characteristics of its sequencing data. This work reports the development of efficient methods to assemble short-read and linked-read sequencing data, named ABySS 2.0 and Tigmint. ABySS 2.0 reduces the memory requirements of short-read genome sequencing assembly by ten fold compared to ABySS 1.0. It does so by using a Bloom filter probabilistic data structure to represent a de Bruijn graph. Tigmint uses linked reads to identify large-scale errors in a genome sequence assembly. Correcting assembly errors using Tigmint before scaffolding improves both the contiguity and correctness of a human genome assembly compared to scaffolding without correction. I have also applied these methods to assemble the 12 gigabase genome of western redcedar (Thuja plicata), which is four times the size of the human genome. Although numerous mitochondrial genomes of angiosperm are available, few mitochondria of gymnosperms have been sequenced. I assembled the plastid and mitochondrial genomes of white spruce (Picea glauca) using whole genome short read sequencing. I assembled the mitochondrial genome of Sitka spruce (Picea sitchensis) using whole genome long read sequencing, the largest complete genome assembly of a gymnosperm mitochondrion. The mitochondrial genomes of both species include a remarkable number of trans-spliced genes. I have developed two additional tools, UniqTag and ORCA. UniqTag assigns unique and stable gene identifiers to genes based on their sequence content. This gene labeling system addresses the inconvenience of gene identifiers changing between versions of a genome assembly. ORCA is a comprehensive bioinformatics computing environment, which includes hundreds of bioinformatics tools in a single easily-installed Docker image, and is useful for education and research. The assembly of linked read and long read sequencing of large molecules of DNA have yielded substantial improvements in the quality of genome assembly projects.

description: Extended object tracking deals with estimating the shape and pose of an object based on noisy point measurements. This task is not straightforward, as we may be faced with scarce low-quality measurements, little a priori information, or we may be unable to observe the entire target. This work aims to address these challenges by incorporating ideas from active contours and exploiting information from negative measurements, which tell us where the target cannot be.

description: In this paper, we focus on the performance of a nanowire Field Effect Transistor (FET) in the Ultimate Quantum Capacitance Limit (UQCL) (where only one subband is occupied) in the presence of interface traps ($D_{it}$), parasitic capacitance ($C_L$) and source/drain series resistance ($R_{s,d}$) using a ballistic transport model and compare the performance with its Classical Capacitance Limit (CCL) counterpart. We discuss four different aspects relevant to the present scenario, namely, (i) gate voltage dependent capacitance, (ii) saturation of the drain current, (iii) the subthreshold slope and (iv) the scaling performance. To gain physical insights into these effects, we also develop a set of semi-analytical equations. The key observations are: (1) A strongly energy-quantized nanowire shows non-monotonic multiple peak C-V characteristics due to discrete contributions from individual subbands; (2) The ballistic drain current saturates better in the UQCL compared to CCL, both in presence and absence of $D_{it}$ and $R_{s,d}$; (3) The subthreshold slope does not suffer any relative degradation in the UQCL compared to CCL, even with $D_{it}$ and $R_{s,d}$; (4) UQCL scaling outperforms CCL in the ideal condition; (5) UQCL scaling is more immune to $R_{s,d}$, but presence of $D_{it}$ and $C_L$ significantly degrades scaling advantages in the UQCL.

description: Swift X-ray observations of the ~60 day super-soft phase of the recurrent nova RS Ophiuchi 2006 show the progress of nuclear burning on the white dwarf in exquisite detail. First seen 26 days after the optical outburst, this phase started with extreme variability likely due to variable absorption, although intrinsic white dwarf variations are not excluded. About 32 days later, a steady decline in count-rate set in. NLTE model atmosphere spectral fits during the super-soft phase show that the effective temperature of the white dwarf increases from ~65 eV to ~90 eV during the extreme variability phase, falling slowly after about day 60 and more rapidly after day 80. The bolometric luminosity is seen to be approximately constant and close to Eddington from day 45 up to day 60, the subsequent decline possibly signalling the end of extensive nuclear burning. Before the decline, a multiply-periodic, ~35 s modulation of the soft X-rays was present and may be the signature of a nuclear fusion driven instability. Our measurements are consistent with a white dwarf mass near the Chandrasekhar limit; combined with a deduced accumulation of mass transferred from its binary companion, this leads us to suggest RS Oph is a strong candidate for a future supernova explosion. The main uncertainty now is whether the WD is the CO type necessary for a SN Ia. This may be confirmed by detailed abundance analyses of spectroscopic data from the outbursts.

Η εκδοχή αυτή συμπυκνώνεται στον ρόλο της μνήμης στη συγκρότηση του «εαυτού», την αναζήτηση της ταυτότητας και την ανάγκη για εξέλιξη προς την επιβίωση. Το σχήμα αυτό φαίνεται να παρουσιάζει συγκεκριμένη δυναμική, στην οποία θα καταλήξει η εργασία.
Οι θεματικές αναλύονται τόσο σημειολογικά βάσει των επιλογών του Mamoru Oshii σε σκηνοθετικό βαθμό, όσο και συγκριτικά με άλλες σκηνοθετικές προσεγγίσεις συναφούς θεματολογίας.

description: Σκοπός της παρούσας διπλωματικής είναι η μελέτη διαφόρων φυσικοχημικών παραμέτρων, για την παραγωγή συνθετικού ζεόλιθου από ιπτάμενη τέφρα. Οι φυσικοχημικές παράμετροι που μελετήθηκαν αφορούσαν: την αναλογία στερεού (τέφρας) - υγρού (καυστικού νατρίου) (S/L), την αναλογία διοξειδίου του πυριτίου-οξειδίου του αργιλίου SiO2Al2O3, την περιεκτικότητα οξειδίου του ασβεστίου (CaO), το χρόνο (t) παραμονής του δείγματος στον κλίβανο κατά την υδροθερμική επεξεργασία και τη θερμοκρασία (T) του κλίβανου.
Αρχικά, έγινε προσδιορισμός  υγρασίας (%), τέφρας (%) και απώλειας πύρωσης (%) του υλικού και στη συνέχεια τα δείγματα υπέστησαν χημική ανάλυση με τη μέθοδο φασματοσκοπίας φθορισμού -Χ (XRF), προκειμένου να ρυθμιστεί κατάλληλα η αναλογία SiO2Al2O3. Στη συνέχεια, έγινε επεξεργασία της τέφρας με HCl (πλυμένη τέφρα) προκειμένου να μειωθεί η περιεκτικότητα σε οξείδιο του ασβεστίου. Έτσι τα πειράματα πραγματοποιήθηκαν με δύο υλικά: την αρχική (ανεπεξέργαστη) και την πλυμένη τέφρα.
Στην πρώτη σειρά πειραμάτων η τέφρα (αρχική ή πλυμένη), αναμίχθηκε με καυστικό νάτριο (NaOH) και σε μερικές περιπτώσεις έγινε προσθήκη SiO2 ή Al2O3. Το διάλυμα επεξεργάστηκε υδροθερμικά για τη δημιουργία κρυσταλλικής δομής.
Στη δεύτερη σειρά πειραμάτων, τέφρα (αρχική ή πλυμένη) αναμίχθηκε με λειοτριβημένες πελλέτες καυστικού νατρίου (NaOH). Η θέρμανση των στερεών του μίγματος στους 5500C (σε μερικά πειράματα), η υδροθερμική επεξεργασία, η ανάδευση του μίγματος καθώς επίσης η επεξεργασία με τη μέθοδο των υπερήχων, εφαρμόστηκαν με διαφορετική σειρά σε κάθε πείραμα, ώστε να αξιολογηθεί η πιο αποτελεσματική αλληλουχία (σειρά) για τη σύνθεση ζεολιθικών δομών. Φαίνεται πως η χρήση υπερήχων μετά την υδροθερμική επεξεργασία είχε θετική επίδραση στη μείωση του άμορφου υλικού.
Επιπρόσθετα, έγινε ορυκτολογική ανάλυση με περιθλασίμετρο ακτίνων-X (XRD) στα υλικά που προέκυψαν μετά το πέρας των πειραμάτων, ώστε να ανιχνευθεί η ύπαρξη ζεολιθικού σχηματισμού. Ακόμη διεξάχθηκε κοκκομετρική ανάλυση τέφρας και προσδιορίστηκε η ειδική επιφάνεια (BET) η οποία δείχνει να επηρεάζεται από το μέγεθος της διαμέτρου των κόκκων του υλικού. Oι λεπτόκοκκες τέφρες δείχνει να ευνοούν τη σύνθεση ζεόλιθων.
Σύμφωνα με τα αποτελέσματα, η θερμοκρασία είναι η πιο σημαντική παράμετρος για τη σύνθεση κρυσταλλικών δομών. Από την άλλη, για τη σύνθεση ενός είδους ζεόλιθου ο πιο σημαντικός παράγοντας φαίνεται να είναι ο λόγος S/L, ακολουθούμενος από την θερμοκρασία και την αναλογία SiO2Al2O3. Συμπερασματικά, η σύνθεση ζεόλιθου αποτελεί μια αρκετά περίπλοκη διαδικασία που εξαρτάται από πολλούς παράγοντες.

description: In the Big Data world, where information continuously and rapidly keeps increasing, research interest focuses on the discovery of new and more effective methods for data analysis. On this premise, studies are being conducted and combined from multiple research fields, such as Business Administration (Optimization, Multi-Criteria Aid, etc.), as well as new ways of implementation and collaboration with the development of new classifiers or ensemble classifiers. The purpose of this thesis is to develop a system that supports the application of optimization methods to Big Data Analysis, combining the Multi-Criteria Decision Aid methods TOPSIS, UTASTAR and UTADIS with machine learning methods, such as k-means. First off, various datasets were gathered from open data libraries on the web (UCI repository), followed by the required pre-processing procedures. The methods implemented on the system were applied on these datasets, both individually and in combination, with the purpose of supporting the greater knowledge extraction from data regarding ranking and classification/clustering problems. Lastly, the results of the aforementioned methods were evaluated for greater information gain and future research proposals.

description: Spitzer/IRS has revealed many sources with very deep Si features at 9.7micron (tau>1). We set out to investigate whether a strong Si absorption feature is a good indicator for the presence of a heavily obscured AGN. We compile X-ray spectroscopic observations available in the literature on the optically-thick,tau(9.7)>1 sources from the IRAS Seyfert sample. We find that the majority of the high-tau optically confirmed Seyferts (6/9) in this sample are probably CT. Thus we provide direct evidence for a connection between mid-IR optically-thick galaxies and CT AGN, with the success rate being close to 70% in the local Universe. This is at least comparable, if not better, than other rates obtained with photometric information in the mid to far-IR, or even mid-IR to Xray. However, this technique cannot provide complete CT AGN samples,ie there are many CT AGN which do not show significant Si absorption, with the most notable example being N1068. Having assessed the validity of the high 9.7micron technique locally, we attempt to construct a sample of candidate CT AGN at higher redshifts. We compile a sample of 7 high-tau sources in the GOODS and 5 in the Spitzer FLS. All these have been selected to have no PAH features EW(6.2)<0.3 in order to maximize the probability that they are AGN. 6 out of 7 sources in the GOODS have been detected in X-rays, while for the five FLS sources only X-ray flux upper limits are available. The high X-ray luminosities of the detected GOODS sources corroborates that these are AGN. For FLS, ancillary optical spectroscopy reveals hidden nuclei in two more sources. SED fitting can support the presence of an AGN in the vast majority of sources. We cannot derive useful X-ray spectroscopy constraints on whether these are CT. However, the low LX/L6 ratios, suggest that at least 4 out of the 6 detected sources in GOODS may be associated with CT AGN.

description: Radiative transfer has a strong impact on the collapse and the fragmentation of prestellar dense cores. We present the radiation-hydrodynamics solver we designed for the RAMSES code. The method is designed for astrophysical purposes, and in particular for protostellar collapse. We present the solver, using the co-moving frame to evaluate the radiative quantities. We use the popular flux limited diffusion approximation, under the grey approximation (one group of photon). The solver is based on the second-order Godunov scheme of RAMSES for its hyperbolic part, and on an implicit scheme for the radiation diffusion and the coupling between radiation and matter. We report in details our methodology to integrate the RHD solver into RAMSES. We test successfully the method against several conventional tests. For validation in 3D, we perform calculations of the collapse of an isolated 1 M_sun prestellar dense core, without rotation. We compare successfully the results with previous studies using different models for radiation and hydrodynamics. We have developed a full radiation hydrodynamics solver in the RAMSES code, that handles adaptive mesh refinement grids. The method is a combination of an explicit scheme and an implicit scheme, accurate to the second-order in space. Our method is well suited for star formation purposes. Results of multidimensional dense core collapse calculations with rotation are presented in a companion paper.
