In the algorithm we first determine an explicit constant $D_p$ so that $|D|> D_p$ implies that the map is necessarily surjective and then we compute explicitly the cases $|D|

description: We discuss the Kaluza-Klein threshold correction to low energy gauge couplings in theories with warped extra-dimension, which might be crucial for the gauge coupling unification when the warping is sizable. Explicit expressions of one-loop thresholds are derived for generic 5D gauge theory on a slice of AdS_5, where some of the bulk gauge symmetries are broken by orbifold boundary conditions and/or by bulk Higgs vacuum values. Effects of the mass mixing between the bulk fields with different orbifold parities are included as such mixing is required in some class of realistic warped unification models.

description: We present our study of the hadronization structure of both vector and axial-vector currents leading to decays of the tau into two kaons and a pion. The cornerstones of our framework are the large-N_C limit of QCD, the chiral structure exhibited at low energies and the proper asymptotic behaviour, ruled by QCD, that is demanded to the associated form factors. The couplings of the theory are mostly constrained by this procedure and upon the analysis of BaBar data on e^+e^- -> KK pi we are able to predict the hadronic spectra.

description: RR Lyrae stars (RRLS) belong to population II and are generally used as a tracer of the host galaxy halo. The surface as well as vertical distribution of RRLS in the inner Large Magellanic Cloud (LMC) are studied to understand whether these stars are actually formed in the halo. RRLS identified by the OGLE III survey are used to estimate their number density distribution. The scale-height of their distribution is estimated using extinction corrected average magnitudes of ab type stars. The density distribution mimics the bar, confirming results in the literature. The distribution of their scale height indicates that there may be two populations, one with smaller scale-height, very similar to the red clump stars and the other, much larger. The distribution of the reddening-corrected magnitude along the minor axis shows variation, suggesting an inclination. The inclination is estimated to be i = 31.3 (3.5) degrees, very similar to the inclination of the disk. Thus, the RRLS in the inner LMC mimic the bar and inclination of the disk, suggesting that a major fraction of RRLS is formed in the disk of the LMC. The results indicate that the RRLS in the inner LMC trace the disk and probably the inner halo. They do not trace the extended metal-poor halo of the LMC. We suggest that a major star formation event happened in the LMC at 10-12 Gyrs ago, resulting in the formation of most of the inner RRLS, as well as probably the globular clusters, inner halo and the disk of the LMC.

description: Choice of source, nitrogen rate, and its application method affect cotton productivity. In absence of new recommendations for recently introduced neem-coated urea (NCU) in India, farmers have been applying either similar or above optimal levels of NCU in cotton just like conventional urea. The present study aimed to evaluate the optimum dose and better method of NCU application to improve cotton productivity and profitability under arid climates. A total of eight different treatments were evaluated in a randomized complete block design. Two NCU doses [i.e., 112.5 kg ha−1 (75% of conventional nitrogen [urea] recommendation-CNR) and 150 kg ha−1 (100% of CNR)] were applied using three methods, i.e., (a) band application, (b) spot application, and (c) broadcasting constituted six treatments. In addition, foliar sprays of NCU@1% and KNO3@2% were also evaluated to study their effect in improving seed cotton yield (SCY) and fiber parameters. These findings elucidated that the spot method of NCU application proved better than the broadcasting and band application method owing to better nitrogen use efficiency (NUE). NCU@ 112.5 kg N ha−1 applied through spot application along with three foliar sprays of KNO3@2% resulted in similar profitability as that of broadcasting 150 kg NCU ha−1 along with four foliar sprays of KNO3. Improved physiological parameters like net photosynthesis and chlorophyll coupled with higher NUE played a decisive role for at par SCY despite 25% low nutrient input besides enhanced environment safety. Therefore, under semi-arid climates, 37.5 kg N ha−1 could be saved without compromising cotton productivity.

description: We report on an experimental study of the dynamics of the reflection of ultracold atoms from a periodic one-dimensional magnetic lattice potential. The magnetic lattice potential of period 10 \textmu m is generated by applying a uniform bias magnetic field to a microfabricated periodic structure on a silicon wafer coated with a multilayered TbGdFeCo/Cr magneto-optical film. The effective thickness of the magnetic film is about 960 nm. A detailed study of the profile of the reflected atoms as a function of externally induced periodic corrugation in the potential is described. The effect of angle of incidence is investigated in detail. The experimental observations are supported by numerical simulations.

The Radio Properties of Type 2 Quasars

description: This paper presents the first high-resolution and high-sensitivity study of the radio properties of optically selected type~2 quasars. We used the Very Large Array at 8.4 GHz to observe 59 sources drawn from the Sloan Digital Sky Survey sample of Zakamska et al. (2003). The detection rate of our survey is 59% (35/59), comparable to the detection rate in FIRST at 1.4 GHz. Ongoing star formation, although present, contributes negligible radio emission at the current sensitivity limit. Comparing the radio powers with the [O III] $λ$5007 luminosities, we find that roughly 15%$\pm$5% of the sample can be considered radio-loud. Intriguingly, the vast majority of the detected sources in our sample fall in a region intermediate between those traditionally occupied by radio-loud and radio-quiet quasars. Moreover, most of these "radio-intermediate" sources tend to have flat or inverted radio spectra, which we speculate may be caused by free-free absorption by ionized gas in the narrow-line region. The incidence of flat-spectrum sources in type 2 quasars appears to be much higher than in type 1 quasars, in apparent violation of the simple orientation-based unified model for active galaxies.

The relationship between the blood flow and the marrow cavity pressure of bone
Creators: name: Hawk, Hubert Edmund
Publisher: name: University of British Columbia
Year: 2011

description: An experimental animal model was developed to study and define the relationship between the blood flow and the marrow cavity pressure of bone. The study was carried out in 24 rabbits and 32 dogs under nembutol anesthesia. A multichannel physiograph was used to record simultaneously the systemic blood pressure, bone blood flow, marrow cavity pressure of bone and time sequence. The systemic blood pressure was measured by cannulating a brachial or carotid artery. The bone blood flow was measured by cannulating the nutrient vein and/or the nutrient artery. The marrow cavity pressure was measured by inserting a steel cannula through a drill hole in the cortex into the marrow cavity. The bones studied were mainly the tibia and femur. During the normal control condition, the marrow cavity pressure was found to have a wide range from animal to animal. In the rabbits, the range was from 20 to 60 mm. Hg. (15 to 50 percent of the systemic blood pressure). In the dogs, it ranged from 40 to 120 mm. Hg. (20 to 90 percent of the systemic blood pressure). However, the systemic blood pressure, intramedullary pressure and nutrient venous outflow were remarkably constant in a control period, therefore, their changes under experimental conditions were readily recordable. Various factors affecting bone circulation were studied. If the femoral vein is occluded the marrow cavity pressure rises and the nutrient venous outflow increases indicating venous congestion of bone. Nutrient artery occlusion causes a sharp fall in marrow cavity pressure coupled with a marked decrease in the nutrient venous outflow. Adrenalin and noradrenalin intravenous infusions produce a fall in marrow cavity pressure coupled with a decreased bone blood flow, despite an elevation in the systemic blood pressure. Isoproterenol hydrochloride generally causes a fall in the systemic blood pressure, widening of the pulse pressure, a fall in the marrow cavity pressure and a decrease in the nutrient venous outflow. Electrical sympathetic stimulation produces a fall in the marrow cavity pressure and a decrease in bone blood flow. Lumbar sympathectomy causes a rise in the marrow cavity pressure and an increase in the bone blood flow. Skeletal muscle contraction produces bone venous congestion with elevation of the marrow cavity pressure and increased nutrient venous outflow. Muscular relaxation causes a momentary sharp fall in the marrow cavity pressure to sub control levels before returning to the normal pressure. It is concluded that the marrow cavity pressure is bone blood flow dependent and reflects well the changes in the hemodynamics of bone. The narrow pressure rises if the arterial blood supply to bone increases or the venous congestion occurs in bone. The marrow pressure falls if the arterial blood supply to bone decreases or the venous drainage of bone is facilitated.
A study of George Herbert's Passio Discerpta and Lucus in the context of the tradition of the sacred epigram
Creators: name: Alexander, Irene Rosalyn
Publisher: name: University of British Columbia
Year: 2011

description: The critical neglect of the neo-Latin poetry of English writers, particularly those of the Renaissance and seventeenth century, presents a difficulty for those students interested in understanding the entire career of an Anglo-Latin author. In Herbert's case, his neo-Latin poetry presents very distinctive aspects of his literary character and techniques, a knowledge of which may enable future readers to better appreciate The Temple, Herbert's major English work. This thesis deals with Passio Discerpta (The Events of the Passion) and Lucus (The Sacred Grove) in particular, and demonstrates their firm place in the tradition of the sacred epigram. In order to form a clearer impression of the tradition and Herbert's work within it and of the contemporary models and sources upon which he drew, Chapter Two surveys briefly the epigrammatic conventions and religious background from which the sacred epigram derived. The differences between the epigrammatic style of Martial and of The Greek Anthology are discussed as well as the similarities between the satiric and the sacred epigram. Chapter Three presents a comparison with other poets of the period working within the same convention, most notably Crashaw, but also such writers as John Saltmarsh, Francis Thynne, and John Pyne. This comparison shows Herbert's superiority to previous writers in his use of the epigram for religious subject-matter. Herbert's skilful use of the conventions of the sacred epigram as a means of expressing his own deep religious feeling is demonstrated in the critical studies of Passio Discerpta and Lucus which form Chapters Four and Five, the core of this thesis. These chapters deal with the poems under the headings of arrangement, imagery, and narrative voice. The analysis of these various aspects reveals significant links between the arrangement of the poems within each volume and the imagery Herbert uses to express his themes. The thematic unity, the conscious selectivity of subject-matter, and the skilful use of the narrative voice as an integral part of the rhetorical structure are shown. On the basis of this study, Herbert's sacred epigrams as exemplified by Passio Discerpta and Lucus are seen as forming aesthetic landmarks in that tradition, and as providing a new perspective from which students of The Temple may understand more fully Herbert's entire literary career.
Fostering engagement with the first R and the ELs : teachers' practices withstanding the test of time

description: Reading has the power to take control of our emotions, to make us laugh and to bring tears to our eyes. Through reading, we can inhabit and experience worlds and cultures past, present and of the imagination. Time can pass unnoticed as we engage \\Vith the characters of a book, characters so reai to us that they can vanquish loneliness, and support us through times of trouble. Reading is also the single most important tool for learning and so the visionary teachers who can give their students the gift of a love of reading are equipping them with a potent force. This case study investigated the practice of four upper pnmary teachers to discover their motivations and objectives for the implementation of a specific combination of three literacy practices: reading aloud to students, providing dedicated silent reading time and engaging students in 'book talk'. The teachers' and students' perceptions of the benefits to students of the programs were also investigated. As this study took place in a time of politico-theoretical debate on reading instruction, and during a time of a change to a values- and futures-oriented curriculum within Tasmania, this study also sought to determine the relevance of these teachers' practices in a time of curriculum change. Results indicated that the teachers' personal love of reading and their understanding of the importance of well-developed reading skills to the future success of their students were the primary motivating factors for teachers' programs. Teachers also had a nai:ve conceptual understanding of the attitude influence model that framed the boundaries of this study. This study provides support for the implementation of the practices implemented by the participating teachers and it shows the power of teacher modelling as a vitaJ component of pedagogical practice. The teachers' narrative accounts provide access to their emotional commitment to their work, and their stories suggest that they implicitly understand the crucial importance of student motivation to any educational endeavour.
Access to power: the organisational structure of the wilderness conservation and anti-nuclear movements in Australia
Creators: name: Holloway, G
Publisher: name: University Of Tasmania
Year: 2023

description: Social movements open new modes of political participation. The placement of social movements exclusively in the domain of 'unconventional' politics ignores their 'conventional' aspects and reinforces the ideological stereotypes that devalue social movements as 'abnormal'. On the other hand, treating social movements as a mere extension of 'conventional' politics tends to ignore the semiinstitutional nature of some social movements bodies. A discussion of these theoretical and ideological issues in Chapters One and Two opens the way for an empirical examination of social movement bodies in Chapters Four to Six. Empirical analysis of organisations and groups forming the wilderness conservation and the anti-nuclear movements in Australia reveals their multi-modal structure and operation. Both movements include formalised organisations, which operate in 'conventional' ways (Institutional Mode) similiar to other interest and lobby groups, as well as movement bodies that are 'unconventional' in their structure and operation. The latter include two types analysed, under the labels 'Social Movement Mode' and the 'New Mode'. The characteristics of these three modes are investigated using a survey of 330 movement bodies (formal and semi-formal). Cluster analysis of the organisational characteristics reveals both the three-modal structure of the movements and some interesting differences between the wilderness conservation and the anti-nuclear movements.

description: We present results from a deep Chandra observation of Abell 2052. A2052 is a bright, nearby, cooling flow cluster, at a redshift of z=0.035. Concentric surface brightness discontinuities are revealed in the cluster center, and these features are consistent with shocks driven by the AGN, both with Mach numbers of approximately 1.2. The southern cavity in A2052 now appears to be split into two cavities with the southernmost cavity likely representing a ghost bubble from earlier radio activity. There also appears to be a ghost bubble present to the NW of the cluster center. The cycle time measured for the radio source is approximately 2 x 10^7 yr using either the shock separation or the rise time of the bubbles. The energy deposited by the radio source, including a combination of direct shock heating and heating by buoyantly rising bubbles inflated by the AGN, can offset the cooling in the core of the cluster.

description: A spin relaxation mechanism is proposed based on a second-order spin-flip intersubband spin-orbit coupling together with the spin-conserving scattering. The corresponding spin relaxation time is calculated via the Fermi golden rule. It is shown that this mechanism is important in symmetric GaAs (110) quantum wells with high impurity density. The dependences of the spin relaxation time on electron density, temperature and well width are studied with the underlying physics analyzed.

Statics and dynamics of suspension bridges with notes on suspension cables and nets
Creators: name: Hegab, HIA
Publisher: name: University Of Tasmania
Year: 2023

description: A historical review of the construction and erection of suspension bridges, and of the literature on them, is presented. Suspension bridges are of ten analysed as plane structures, as if a bridge has only one cable supporting a narrow deck with no torsional stiffness and no torsional stresses. The statics and dynamics of a laboratory model of such a single cable bridge are investigated both experimentally and analytically, followed by a short chapter on the dynamics of suspension cables and nets . A real suspension bridge has usually two or more cables supporting a deck with some width and some torsional stiffness, and undergoes torsion . A laboratory model for a two-cable bridge was designed and built. A method for the static analysis of such a two-cable bridge is derived and used for both the static and dynamic analyses of the model. Measurements of the static deflections and natural frequencies and modes of vibration of the model showed good agreement with calculations. A chapter comprising some notes on the aerodynamic instability of suspension bridges is also included.

description: Hard X-ray surveys have proven remarkably efficient in detecting intermediate polars and asynchronous polars, two of the rarest type of cataclysmic variable (CV). Here we present a global study of hard X-ray selected intermediate polars and asynchronous polars, focusing particularly on the link between hard X-ray properties and spin/orbital periods. To this end, we first construct a new sample of these objects by cross-correlating candidate sources detected in INTEGRAL/IBIS observations against catalogues of known CVs. We find 23 cataclysmic variable matches, and also present an additional 9 (of which 3 are definite) likely magnetic cataclysmic variables (mCVs) identified by others through optical follow-ups of IBIS detections. We also include in our analysis hard X-ray observations from Swift/BAT and SUZAKU/HXD in order to make our study more complete. We find that most hard X-ray detected mCVs have P_{spin}/P_{orb}<0.1 above the period gap. In this respect we also point out the very low number of detected systems in any band between P_{spin}/P_{orb}=0.3 and P_{spin}/P_{orb}=1 and the apparent peak of the P_{spin}/P_{orb} distribution at about 0.1. The observational features of the P_{spin} - P_{orb} plane are discussed in the context of mCV evolution scenarios. We also present for the first time evidence for correlations between hard X-ray spectral hardness and P_{spin}, P_{orb} and P_{spin}/P_{orb}. An attempt to explain the observed correlations is made in the context of mCV evolution and accretion footprint geometries on the white dwarf surface.

description: We use the thermoacoustic Helmholtz equation to model thermoacoustic oscillations as an eigenvalue problem. We solve this with a Finite Element method. We parameterize the geometry of an annular combustor geometry using Free Form Deformation (FFD). We then use the FFD geometry, define the system parameters and impose the acoustic boundary conditions to calculate the eigenvalue and eigenvector of the problem using a Helmholtz solver. We then use adjoint methods to calculate the shape derivatives of the unstable eigenvalue with respect to the FFD control points. According to these gradients, we propose modifications to the control points that reduce the growth rate. We first demonstrate the application of this approach on the Rijke tube. Then we extend the method to a simulation of a laboratory combustor and lower the growth rate of the unstable circumferential mode. These findings show how this method could be used to reduce combustion instability in industrial annular combustors through geometric modifications.

description: Context. We report the detection by the AGILE satellite of an intense gamma-ray flare from the gamma-ray source 3EG J1255-0549, associated to the Flat Spectrum Radio Quasar 3C 279, during the AGILE pointings towards the Virgo Region on 2007 July 9-13. Aims. The simultaneous optical, X-ray and gamma-ray covering allows us to study the spectral energy distribution (SED) and the theoretical models relative to the flaring episode of mid-July. Methods. AGILE observed the source during its Science Performance Verification Phase with its two co-aligned imagers: the Gamma- Ray Imaging Detector (GRID) and the hard X-ray imager (Super-AGILE) sensitive in the 30 MeV - 50 GeV and 18 - 60 keV respectively. During the AGILE observation the source was monitored simultaneously in optical band by the REM telescope and in the X-ray band by the Swift satellite through 4 ToO observations. Results. During 2007 July 9-13 July 2007, AGILE-GRID detected gamma-ray emission from 3C 279, with the source at ~2 deg from the center of the Field of View, with an average flux of (210+-38) 10^-8 ph cm^-2 s^-1 for energy above 100 MeV. No emission was detected by Super-AGILE, with a 3-sigma upper limit of 10 mCrab. During the observation lasted about 4 days no significative gamma-ray flux variation was observed. Conclusions. The Spectral Energy Distribution is modelled with a homogeneous one-zone Synchrotron Self Compton emission plus the contributions by external Compton scattering of direct disk radiation and, to a lesser extent, by external Compton scattering of photons from the Broad Line Region.

Catholic response to the educational crisis, 1850-1900
Creators: name: Haley, E

description: Fogarty in his history of Catholic Education in Australia makes certain basic assumptions. In the first place he equates the decline of the denominational system of education and the consequent emergence of the national and secularised system of today, with increasing liberalism during the second half of the 19th century and its Catholic reaction. This may lave been so on the Australian mainland colonies, but its impact as far as Tasmania was concerned was practically negligible. As a direct response to this ideology, Fogarty implies that the system of Catholic education was a spontaneous rather than a deliberately planned occurrence. In all colonies the same principles and interests were involved, making the same forces operative. The validity of these factors in relation to Tasmania must be modified to a considerable extent. Here obstacles to the establishment and implementation of the Hierarchy's decrees, while probably more readily apparent, were possibly greater. Van Diemen's Land was one of the earliest of the colonies to be settled. Consequently no matter how primitive, the foundations of its educational system were laid during it's convict era. As well these penal origins were to have a marked bearing on the impact and primary purpose of education.

Planet formation bursts at the borders of the dead zone in 2D numerical simulations of circumstellar disks

description: As accretion in protoplanetary disks is enabled by turbulent viscosity, the border between active and inactive (dead) zones constitutes a location where there is an abrupt change in the accretion flow. The gas accumulation that ensues triggers the Rossby wave instability, that in turn saturates into anticyclonic vortices. It was suggested that the trapping of solids within them leads to a burst of planet formation on very short timescales. We perform two-dimensional global simulations of the dynamics of gas and solids in a non-magnetized thin protoplanetary disk with the Pencil Code. We use multiple particle species of radius 1, 10, 30, and 100 cm, solving for the particles' gravitational interaction by a particle-mesh method. The dead zone is modeled as a region of low viscosity. Adiabatic and locally isothermal equations of state are used. We find that the Rossby wave instability is triggered under a variety of conditions, thus making vortex formation a robust process. Inside the vortices, fast accumulation of solids occurs and the particles collapse into objects of planetary mass in timescales as short as five orbits. Because the drag force is size-dependent, aerodynamical sorting ensues within the vortical motion, and the first bound structures formed are composed primarily of similarly-sized particles. In addition to erosion due to ram pressure, we identify gas tides from the massive vortices as a disrupting agent of formed protoplanetary embryos. We also estimate the collisional velocity history of the particles that compose the most massive embryo by the end of the simulation, finding that the vast majority of them never experienced a collision with another particle at speeds faster than 1 m/s.

Two-sided estimates of minimum-error distinguishability of mixed quantum states via generalized Holevo-Curlander bounds

description: We prove a concise factor-of-2 estimate for the failure rate of optimally distinguishing an arbitrary ensemble of mixed quantum states, generalizing work of Holevo [Theor. Probab. Appl. 23, 411 (1978)] and Curlander [Ph.D. Thesis, MIT, 1979]. A modification to the minimal principle of Cocha and Poor [Proceedings of the 6th International Conference on Quantum Communication, Measurement, and Computing (Rinton, Princeton, NJ, 2003)] is used to derive a suboptimal measurement which has an error rate within a factor of 2 of the optimal by construction. This measurement is quadratically weighted and has appeared as the first iterate of a sequence of measurements proposed by Jezek et al. [Phys. Rev. A 65, 060301 (2002)]. Unlike the so-called pretty good measurement, it coincides with Holevo's asymptotically optimal measurement in the case of nonequiprobable pure states. A quadratically weighted version of the measurement bound by Barnum and Knill [J. Math. Phys. 43, 2097 (2002)] is proven. Bounds on the distinguishability of syndromes in the sense of Schumacher and Westmoreland [Phys. Rev. A 56, 131 (1997)] appear as a corollary. An appendix relates our bounds to the trace-Jensen inequality.
description: It was not realized at the time of publication that the lower bound of Theorem 10 has a simple generalization using matrix monotonicity (See [J. Math. Phys. 50, 062102]). Furthermore, this generalization is a trivial variation of a previously-obtained bound of Ogawa and Nagaoka [IEEE Trans. Inf. Theory 45, 2486-2489 (1999)], which had been overlooked by the author
The art of environmental personhood and the possibility of environmental statehood
Creators: name: Ward, Devon
Publisher: name: Universitat Oberta de Catalunya, The International Symposium for Electronic Art (ISEA)
Year: 2023

description: This paper examines the impact that the concept of environmental personhood has had on art and culture, and suggests that projects such as The Embassy of the North Sea hint at the possibility of environmental statehood. First, it reviews how the Te Awa Tupua (Whanganui River Claims Settlement) Act 2017 – which granted juridical personhood to the Whanganui River in New Zealand – inspired the creation of new works such as Weathering, Embedding: Ochopee Trail, terra0, A Voice for the Eel, and F/EEL. Next, a heuristic model called the agency-personhood continuum (APC) is used to identify the aesthetic tropes of environmental personhood. Analysis indicates that artworks that represent environmental personhood often utilize strategies of amplification, translation, performance, time compression, and metonymy. Finally, this paper seeks to encourage new discussions by suggesting that The Embassy of the North Sea and “Theatre of Negotiations” anticipate the concept of environmental statehood, which has the potential to provide greater protections for natural entities that span multiple countries – such as the Amazon River, the Andes, the Atlantic Ocean, and the Pacific Ocean. Theoretically, environmental statehood could also provide greater representation in supra-governmental assemblies such as the UN General Assembly. Ultimately, this article suggests that the culture-law feedback loop for environmental personhood presents a new ontological paradigm that provides greater recognition of the agency, identity, and sovereignty of natural entities.
Effect of dimensionality on the charge-density-wave in few-layers 2H-NbSe$_2$

description: We investigate the charge density wave (CDW) instability in single and double layers, as well as in the bulk 2H-NbSe$_{2}$. We demonstrate that the density functional theory correctly describes the metallic CDW state in the bulk 2H-NbSe$_{2}$. We predict that both mono- and bilayer NbSe$_{2}$ undergo a CDW instability. However, while in the bulk the instability occurs at a momentum $\mathbf{q}_{CDW}\approx{2/3}\mathbf{ΓM}$, in free-standing layers it occurs at $\mathbf{q}_{CDW}\approx{1/2}\mathbf{ΓM}$. Furthermore, while in the bulk the CDW leads to a metallic state, in a monolayer the ground state becomes semimetallic, in agreement with recent experimental data. We elucidate the key role that an enhancement of the electron-phonon matrix element at $\mathbf{q}\approx\mathbf{q}_{CDW}$ plays in forming the CDW ground state.

description: From the point of view of computational cost, theoretically higher FEM's are very promising. For the realization of the possible advantage in engineering practice it is necessary to predict computer time savings for typical structures. The thesis supplements information on this issue.The importance of obtaining results. It is established that the use: of FEM with the second order finite elements for the important class; of thin walled structures allows to reduce the computational time approximately in 5 times. Among numerical methods of engineering analysis, the finite element method is the most widely used. This method is able to reproduce with satisfactory accuracy stress and deformation states of rather complex engineering structures, made from different materials and exhibiting various specific mechanical properties. In this thesis, the stress/deformation state of beams was numerically analyzed with the use of finite elements of the first and the second accuracy orders. It was revealed, that the element of second order is more accurate and requires much less computer time for reaching the target accuracy of the numerical results at analysis of buildings structures.
Shear Unzipping of DNA

description: We study theoretically the mechanical failure of a simple model of double stranded DNA under an applied shear. Starting from a more microscopic Hamiltonian that describes a sheared DNA, we arrive at a nonlinear generalization of a ladder model of shear unzipping proposed earlier by deGennes [deGennes P. G. C. R. Acad. Sci., Ser. IV; Phys., Astrophys. 2001, 1505]. Using this model and a combination of analytical and numerical methods, we study the DNA "unzipping" transition when the shearing force exceeds a critical threshold at zero temperature. We also explore the effects of sequence heterogeneity and finite temperature and discuss possible applications to determine the strength of colloidal nanoparticle assemblies functionalized by DNA.

description: We obtain equilibrium solutions for rotating compact stars including the special relativistic effects. The gravity is assumed to be Newtonian, but we used the active mass density, which takes into account all the energies such as motions of the fluids, internal energy, pressure energy in addition to the rest mass energy, in computing the gravitational potential using Poisson's equation. Such a treatment could be applicable to the neutron stars with relativistic motions or relativistic equation of state. We applied the Hachisu's self-consistent field (SCF) method to find spheroidal as well as toroidal sequences of equilibrium solutions. Our solutions show better agreement than Newtonian relativistic hydrodynamic approach that does not take into account the active mass, with general relativistic solutions. The physical quantities such as the peak density, equatorial radii of our solutions agree with general relativistic ones within 5%.Therefore our approach can be a simple alternative to the fully relativistic one when large number of model calculations are necessary as it requires much less computational resources.
