description: The second home is an important issue for a housing market and has effects on local land use. Conventional approaches do not consider second homes varying across space and time. Hence, spatial models, such as the Besag, York and Mollie (BYM) model and its variants, offer a feasible way to model both covariates and spatial, temporal dependence. This model is applied in our study to analyse the second home incidence rate at a county level in Corsica, France, over the period 2006–16. We investigate the spatially referenced covariates and localize ‘hot spots’ of the incidence rate across Corsican counties. Further, the temporally structured component reveals that there was a gradual increase in the incidence rate over the period under study.

description: The SPME-GC-MS analysis of the aroma components of Cephalanthera damasonium, Cephalanthera rubra, and Cephalanthera longifolia were reported. The main components found in C. damasonium were pentadecane, hexadecane, heptadecane and α-farnesene. The same compounds were found in the scent of C. rubra. Although C. damasonium and C. rubra have different pollination mechanisms, their spectrum of volatile compounds surprisingly does not differ significantly. In C. longifolia pentadecane and heptadecane were found together with cis-β-farnesene. As C. longifolia is allogamous, the differences in scent composition may play a role in pollinator attraction.

description: We investigate the classicality of linear dipolar droplet arrays through a normal mode analysis of the dynamical properties in comparison to the supersolid regime. The vibrational patterns of isolated-droplet crystals that time-evolve after a small initial kick closely follow the properties of a linear droplet chain. For larger kick velocities, however, droplets may coalesce and separate again, showing distinct deviations from classicality. In the supersolid regime the normal modes are eliminated by a counter-flow of mass between the droplets, signaled by a reduction of the center-of-mass motion.

Exact quantum conformal symmetry, its spontaneous breakdown, and gravitational Weyl anomaly

description: The classical Lagrangian of the Standard Model enjoys the symmetry of the full conformal group if the mass of the Higgs boson is put to zero. This is a hint that conformal symmetry may play a fundamental role in the ultimate theory describing Nature. The origin of scales, such as the Higgs vacuum expectation value (vev), may result from the spontaneous breakdown of the conformal symmetry by the dilaton field. In this work, we study whether this classical setup can be implemented in quantum theory and be phenomenologically viable by presenting an explicit construction where the exact conformal symmetry can be preserved and is anomaly free while being spontaneously broken. Not only the Higgs mass but also the genuine quantum scales like the QCD confinement radius are generated by the dilaton vev. We also discuss the extension of these ideas to the theories with dynamical gravity and show that the only finite subgroup of the local Weyl transformations which is anomaly free corresponds to the global scale symmetry. This means that the conformal invariance of the flat space theory is explicitly broken down to the scale symmetry by gravitational effects related to the Weyl anomaly.

description: Anisotropic D-dimensional polymerized phantom membranes are investigated within a nonperturbative renormalization group (NPRG) framework. One focuses on the transition between a high-temperature, crumpled, phase and a low-temperature, tubular, phase where the membrane is flat along one direction and crumpled along the other ones. While the upper critical dimension - Duc=5/2 - is close to D=2 the weak-coupling perturbative approach is qualitatively and quantitatively wrong. We show that our approach is free of the problems encountered within the perturbative framework and provides physically meaningful critical quantities.

description: Soybean (Glycine max L.) is one of the most important and widely consumed food plants worldwide. The objective of this study was to investigate the metabolite profiling of three Egyptian soybean cultivars (Giza 22, Giza 35 and Giza 111) and their in vivo antitumor effect. Random amplified polymorphic DNA (RAPD) analysis developed polymorphism level of 75% in 72 distinct markers. Applying LC-ESI-MS analysis, twenty-nine metabolites were recognized from the 80% methanol extract of all cultivars. In vivo antitumor activity of the 80% methanolic extract against solid Ehrlich ascites carcinoma (EAC) inoculated in mice model, showed a significant diminishing in tumor volume and reduced Glutathione (rGSH) and a significant increase in malondialdehyde (MDA) which was supported by histopathological examination. Among the studied cultivars, Giza 22 cultivar contained the highest total phenolic content (TPC) that may contribute to its impressive antioxidant capacity and antitumor activity.

description: Simulation of conditional master equations is important to describe systems under continuous measurement and for the design of control strategies in quantum systems. For large bosonic systems, such as BEC and atom lasers, full quantum field simulations must rely on scalable stochastic methods whose convergence time is restricted by the use of representations based on coherent states. Here we show that typical measurements on atom-optical systems have a common form that allows for an efficient simulation using the number-phase Wigner (NPW) phase-space representation. We demonstrate that a stochastic method based on the NPW can converge over an order of magnitude longer and more precisely than its coherent equivalent. This opens the possibility of realistic simulations of controlled multi-mode quantum systems.

Exploring barriers to success for community-based organizations engaged in the adaptive co-management of parkland
Creators: name: Jerowsky, Micheal
Publisher: name: University of British Columbia
Year: 2019

description: For decades, leaders in environmental governance have been directing the attention of their peers towards co-management frameworks. These participatory approaches to land management connect local communities and governments through power-sharing, and enhanced stakeholder engagement. Adaptive co-management is a distinct approach within this tradition that encourages flexibility and adaptability within environmental management through participatory governance, and an iterative, trial-by-error approach to understanding social-ecological systems. However, while the conceptual understanding of adaptive co-management has grown considerably over the years, critics have highlighted that the knowledge and representation of how this process occurs is lacking. This is particularly true regarding parkland. To begin addressing this concern, I conducted a multiple ethnographic case-study of four community-based organizations in Vancouver, British Columbia that are engaged in the adaptive co-management of parkland alongside their regional land manager. Specifically, I aimed to: (1) explore barriers to adaptive co-management related to citizen monitoring, institutional culture, and stakeholder engagement; (2) highlight the lived experience of participants to provide a thicker description for understanding the adaptive co-management process; and (3) suggest solutions and avenues for future research. A broad array of barriers existed for participants in this study. First, a lack of understanding regarding the quality of citizen data has led to funding shortages for citizen monitoring programs, and a regional disparity in their utilization. Second, rigid communication and information technology policies have resulted from unequal organizational growth, and an institutional fear of decentralized technology. Finally, stakeholder engagement has been reduced due to the marginalization of “outsider organizations,” and a lack of actor-level diversity on community boards. In response to these findings, I conclude this thesis with a series of five best practices that are based on suggestions emerging from the literature and my participants: These include: (1) Increased internal funding for citizen monitoring programs; (2) the use of a holistic data quality assessment framework; (3) the adoption of more flexible and transparent communication policies; (4) the adoption of an Agile information technology framework; and (5) the formalization of community-led bridging organizations to support stakeholder mediation.

description: We propose and benchmark a modified time evolution block decimation (TEBD) algorithm that uses a truncation scheme based on the QR decomposition instead of the singular value decomposition (SVD). The modification reduces the scaling with the dimension of the physical Hilbert space $d$ from $d^3$ down to $d^2$. Moreover, the QR decomposition has a lower computational complexity than the SVD and allows for highly efficient implementations on GPU hardware. In a benchmark simulation of a global quench in a quantum clock model, we observe a speedup of up to three orders of magnitude comparing QR and SVD based updates on an A100 GPU.

description: The purpose of this study was to investigate Teachers‟ andStudents „awareness and  preferences
of  online  sources  for  English  Language  Learning/Teaching  at  Wachemo  University.  The
researcher selected the sample University because he had information about it and it is not far
for  the researcher. In order to collect data, questionnaire and interview were  used. Besides, EFL
teachers  and  students  were  participants  of  the  study.  Regarding  selection  of  the  sample,
purposive  sampling  was  used  to  determine  participant  teachers  and  students.  Accordingly,  6
teachers  and  65  students  were  included  as  respondents  of  the  study.  With  regard  to  research
design, the researcher used  both  descriptive survey  and correlation designs. This method was
preferably used to collect information from various participants. Moreover, to analyze data, both
quantitative  and  qualitative  approaches  were  employed.  The  study  showed  that  both  teachers
and  students  had  negative  attitude  towards  awareness  and  preference  of  online  sources  for
English  Language  Learning/Teaching.  It  was  also  found  that  there  was  an  attitudinal  and
preference  link  between  teachers  and  students.  Issues  that  were  identified  as  barriers  to  use
online sources for ELL/ELT were commonly shared by both teachers and students.   Based on
the above findings,  some recommendations  were  forwarded.   These were: there were teachers
and  students  who  did  not  have  awareness  and  preference  for  ELL/ELT.  Therefore,  students,
teachers, concerned bodies like EFL departments, education offices  should prepare trainings to
provide  EFL  teachers  and  students  with  potential  knowledge  and  usage  of  online  sources  for
ELL/ELT.

description: The color neutral two-flavor superconducting (2SC) phase of cold and dense quark matter is studied in the presence of constant magnetic fields and at moderate baryon densities. In the first part of the paper, a two-flavor effective Nambu--Jona-Lasinio model consisting of a chiral symmetry breaking mass gap sigma_{B}, a color superconducting mass gap Delta_{B} and a color neutrality coefficient mu_{8} is introduced in the presence of a rotated U(1) magnetic field B. To study the phenomenon of magnetic catalysis in the presence of strong magnetic fields, the gap equations corresponding to sigma_{B} and Delta_{B}, as well as mu_{8} are solved in the lowest Landau level approximation. In the second part of the paper, a detailed numerical analysis is performed to explore the effect of any arbitrary magnetic field on the above mass gaps and the color neutrality coefficient. The structure of the chiral symmetry breaking and color superconducting phases is also presented in the mu_{c}-B plane, and the effect of the color neutrality coefficient mu_{8} on the phase structure of the model is explored. As it turns out, whereas the transition from the chiral symmetry breaking to color superconducting phase is of first order, nonvanishing mu_{8} affects essentially the second order phase transition from color superconducting to the normal phase.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Observations of white dwarfs in dark matter-rich environments can provide strong limits on the strength of dark matter interactions. Here we apply the recently improved formalism of the dark matter capture rate in white dwarfs to a general model in which dark matter interacts with the white dwarf ion components via a light scalar mediator. We compute the dark matter capture rate in the optically thin limit in a cold white dwarf from the globular cluster Messier. We then estimate the threshold cross-section, which significantly varies as a function of the light scalar mediator mass $m_ϕ$ in the range of $0.05\, m_χm_χ$. We also show that the bounds obtained from the dark matter capture in a white dwarf from the globular cluster Messier 4 are complementary to direct detection experiments and particularly strong in the sub-GeV regime.

description: Unmovable nodal points (UNP) and lines (UNL) are band crossings which positions in the Brillouin zone are unaltered by symmetry preserving perturbations. Not only positions but also the band structure in the vicinity is determined by the little group of a wave vector and it's irreducible (co)representations. In this paper we give the full set of electronic dispersions near all UNPs and UNLs in non-magnetic, quasi two-dimensional (2D) materials both with and without spin-orbit coupling (SOC). Analysis of all layer gray single and double groups gives nineteen different quasiparticles, great majority of which are unavoidable for a 2D material which belongs to certain layer groups. These include Weyl and Dirac nodal lines, dispersions with quadratic or cubic splitting, anisotropic Weyl and Dirac cones which orientation can be varied by e.g. strain etc. We indicated qusiparticles that are robust to SOC. For convenience, our results are concisely presented graphically - as a map, not in a tabular, encyclopedia form. They may be of use as checkpoints or for fitting of experimentally (via e.g. ARPES) and numerically obtained electronic band structures as well as for deeper theoretical investigations.

description: This study  was designed to investigate  the “benefits  and challenges of computer assisted
language learning” between summer and regular TEFL MA students of Arba Minch University.
A descriptive design with a mixed approach (quantitative and qualitative), and a comprehensive
sampling technique were  employed using  39  (35  summer  and  4 regular)  respondents.
Questionnaire and interview were used to accomplish this  study. Descriptive statistics, such as
frequencies and percentages were used  to determine  the summer and regular students‟ benefits
and challenges of CALL. Content analysis technique was used to analyze the interview and non-
parametric, Mann-Whitney- Test (SPSS version 20) used to analyze and check  the summer and
regular students‟ differences on the benefits and challenges of CALL. The results indicated that
the majority of  summer and almost all  regular students had practiced CALL  very well. When
seeing both groups‟ benefits of CALL, there is no significant difference. On the other hand, the
summer and regular students‟ challenges of CALL were identified, and both experienced various
challenges in learning CALL. The result  indicated that there was no significant difference
between the two groups. The findings of the study indicated that students have got the benefits of
computer assisted language learning. Moreover, the findings showed that students need basic
computer skills/training should be required to learn with computers, and adequate time should
also be given for CALL learners.

This review has been carried out following similar work performed under the auspices of OECD/WPEC-Subgroup 25 (2005-2007) and the International Atomic Energy Agency (2010, 2014), and various highly relevant TAGS measurements completed as a consequence of such assessments. We present our recommendations for new decay-data evaluations, along with possible requirements for total absorption and discrete high-resolution gamma-ray spectroscopy studies that cover approximately 120 fission products and various isomeric states.

description: We study the fluctuations and correlations of conserved charges, i.e. the baryon number, electric charge and the strangeness at finite temperature and nonzero baryon chemical potential with an effective model. The fluctuations are calculated up to the fourth-order and the correlations to the third-order. We find that the second-order fluctuations and correlations have a peak or valley structure when the chiral phase transition takes place with the increase of the baryon chemical potential; the third-order fluctuations and correlations change their signs during the chiral phase transition and the fourth-order fluctuations have two maximum and one minimum. we also depict contour plots of various fluctuations and correlations of conserved charges in the plane of temperature and baryon chemical potential. We find that higher order fluctuations and correlations of conserved charges are superior to the second-order ones to be used to search for the critical point in heavy ion collision experiments.

description: We investigate the ground-state phase diagram of a modified spinless Haldane-Hubbard model with broken threefold rotational symmetry, employing exact diagonalization calculations. The interplay of asymmetry, interactions, and topology gives rise to a rich phase diagram. The non-interacting limit of the Hamiltonian exhibits a higher-order topological insulator characterized by the existence of corner modes, in contrast to known chiral edge metallic states of the standard Haldane model. Our investigation demonstrates that these symmetry-protected states are robust to the presence of finite interactions. Furthermore, in certain regimes of parameters, we show that a topological Mott insulator exists in this model, where a non-trivial topological bulk coexists with an interaction-driven charge-density-wave, whose emergence is characterized by a $Z_2$-symmetry breaking within the 3$d$-Ising universality class.

ENLISH LANGUAGE TEACHERS’ ATTITUDES, PRACTICES AND  CHALLENGES IN TEACHING WRITING SKILLS THROUGH PROCESS  APPROACH: THE CASE OF KINDO HALALE PREPARATORY SCHOOL
Creators: name: MELESE YOHANNES WADA
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The  purpose of this study was  firstly,  to examine  the extent of implementation of process  approach;
secondly, to explore English language teachers’ attitudes towards teaching writing skills through
process approach and thirdly to identify the  major  challenges  which English language have been
facing during teaching writing as process at Halale  preparatory school grade 11 and 12. To achieve
this,  the  researcher  adopted  case  study  design.  The  major  research  tool  was  semi-structured
interview conducted  with  six English teachers to answer two research questions. The second one
was classroom observation conducted with both grades  (1 from grade 11 and 2 from grade 12).
The third one was evaluation of documents (teachers’ annual and daily lesson plans) to support
the data collected through observation. In an attempt to investigate the attitudes of teachers about
teaching  writing  skills  through  process  approach,  the  results  from  both  open  and  close  ended
interviews revealed that  all  the respondents were of the attitude that they like process approach
than the product one, however, the product approach was  mostly practiced in grade 11 and in grade
12 both approaches were employed side by side but still the process approach was implemented to
the minimal extent. In investigating the challenges which were responsible not to appropriately
implement the process  approach in  writing skills classes, the following problems were identified
as dominant constraints: time constraint, students’ weak background in writing, large class size,
lack of in-service training and shortage of reference materials were  some  among others. In sum,
though  the  teachers  positively  perceive  teaching  writing  skills  through   process  approach,  its
practice has not yet been given full attention at Halale secondary and preparatory schoo
EXPLORING STUDENTS‟  AWARENESS AND TEACHERS‟ CONSIDERATION  OF  PERCEPTUAL LEARNING STYLE PREFERENCES  IN ENGLISH CLASSROOMS:  THE CASE OF GRADE 10  STUDENTS AND  EFL TEACHERS  OF FOUR  SECONDARY SCHOOLS IN HOSSANA TOWN ADMINISTRATION

Year: 2018

description: The purpose of this study was to explore students‟ awareness and teachers‟ consideration
of perceptual learning style preferences in English classrooms. To conduct the study,
descriptive survey deign was used. And both quantitative and qualitative data gathering
method was applied.  The study was carried out in Hadiya Zone Hossana Town
Administration. Among eleven secondary schools of Hossana Town Administration, four
secondary schools were selected by using simple random sampling technique.
Comprehensive sampling  technique  was employed to take all grade 10 English language
teachers from the selected schools. The main instruments of data collection were
questionnaire and observation.  Accordingly, a questionnaire was administered to 200
randomly selected grade 10 students from the four secondary schools.  And the
observation  of teachers  was  substantiated by an interview. Then, the data were analyzed
using percentage and overall mean of each preferences. The finding of the study revealed
that there is lack of students‟ awareness of their perceptual learning style preferences with
the exception of visual learners, and  English Language  teachers, except teachers who
considered auditory learners,  did not have clear consideration about their students‟
perceptual learning style preferences  as well. Finally, the recommendations were
forwarded based on the findings. To control their own learning, students need to be aware
of their perceptual learning style preferences, and  to meet the need of individuals‟
learning preferences, English Language teachers need to survey  and identify  their
students‟ perceptual learning style preferences  first;  were some of the recommendations
from  the findings.  So as to reduce and gradually solve the problems encountered in
effective implementation of varying instructional methods of teachers based on the
students‟  preferred needs of perceptual learning style preferences,  English Language

description: We present LDA band structure of novel hole doped high temperature superconductors (Tc~30K) KxFe2Se2 and CsxFe2Se2 and compare it with previously studied electronic structure of isostructural FeAs superconductor BaFe2As2 (Ba122). We show that stoichiometric KFe2Se2 and CsFe2Se2 have rather different Fermi surfaces as compared with Ba122. However at about 60% of hole doping Fermi surfaces of novel materials closely resemble those of Ba122. In between these dopings we observe a number of topological Fermi surface transitions near the G point in the Brillouin zone. Superconducting transition temperature Tc of new systems is apparently governed by the value of the total density of states (DOS) at the Fermi level.

description: Three-dimensional topological insulators possess various interesting properties that are promising for various modern applications, including in the recently emerging fields of ultrafast THz photonics and spintronics. Their gapless spin-momentum-locked topological surface states with the presence of chiral spin structure are relevant for the development of light helicity-sensitive THz emitters and detectors. In this paper, we report femtosecond excitation pulse wavelength and helicity-dependent response of the three-dimensional topological insulators for an enhanced broadband THz pulse emission. Specifically, the excitation wavelength has been varied in a large range from near UV to near IR and two model systems of Bi2Te3 and Bi2Se3 single crystals have been studied. It was observed that the photoexcitation at shorter wavelengths enhances the THz emission from both the surface and bulk states. Primarily, circular photogalvanic effect is responsible for the surface contribution, while the prominent contribution in the bulk is from photon-drag effect. The wavelength-dependence of the THz emission is explained by accounting for the free carrier absorption of THz radiation within the material accurately.

description: The present study focuses on the emitted and endogenous scent profiles of Uvaria hamiltonii flowers. Among the 34 compounds identified, sesquiterpenoids were found to dominate the floral volatiles composition. Profiles from endogenous scent volatiles showed higher number of compounds than the emitted ones. The anthocyanin pigment responsible for the flower colour was also explored. It was found that a single anthocyanin compound, cyanidin-3-O-glucoside, was principally responsible for petal colour. Total phenolic content was evaluated and antioxidant capacities were studied with the help of DPPH, FRAP and ABTS assays. The total phenolic content and the antioxidant capacity were higher in methanolic extract as compared to aqueous, petroleum ether and ethyl acetate extracts of U. hamiltonii flowers.
LEARNERS’ PERCEPTIONS OF TEACHERS’ ORAL AND WRITTEN  FEEDBACK ON WRITING ESSAYS IN EFL CLASSES: WAKA SENIOR  SECONDARY AND PREPARATORY SCHOOL GRADE 11 STUDENTS IN  FOCUS
Creators: name: ABRAHAM ABERA
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: This study was conducted to assess the learners’ perceptions of teachers’ oral and written
feedback on writing essays. Descriptive survey with correlation design was used to conduct
the research.  To conduct the study, the researcher took 169 students from 482 students by
systematic random sampling method. Then to collect data, questionnaire and interview were
employed. The questionnaire data was collected by using likert scales. Moreover, to analyze
the data gathered by using questionnaire, SPSS was used. To know deeply the learners’
perceptions oral feedback, the researcher classified oral feedback to corrective oral feedback
and positive oral feedback. The finding showed that the learners wanted to receive corrective
oral feedback more than positive oral feedback to improve their essays. Furthermore, to
know the learners’ perceptions’ of written feedback, the researcher  classified written
feedback in to corrective written feedback and positive written feedback. Then the corrective
written feedback classified into direct corrective written feedback and indirect  corrective
written feedback. The finding showed that the learners perceived  both  direct and indirect
corrective written feedbacks as important ingredient to improve their essays. In aggregation,
the finding indicated that  learners give more attention to corrective written feedback than
positive written feedback.  Moreover, the  relation between oral and  written feedback
indicated that corrective oral feedback has positive relation with direct and indirect
corrective written feedback.  It has also negative relation with positive written and positive
oral feedback. Finally, the recommendation and further study areas were made based on
findings.

description: The phytochemical investigation of the methanol extract of the bark of Croton oligandrus Pierre ex Hutch yielded a new clerodane-type diterpenoid crotoliganfuran (1) along with ten other compounds including 12-epicrotocorylifuran (2), lupeol (3), syringic acid (4), aleuritolic acid acetate (5), aleuritolic acid (6), scopoletin (7), geddic acid (8), β-sitosterol (9), vanilic acid (10) and stigmastane-3,6-dione (11). Their structures were established by spectroscopic means. The extract and all the isolates were screened for their inhibitory properties against butyrylcholinesterase and urease enzymes, respectively. The extract and compounds 1, 4 and 7 displayed the most potent urease inhibitory properties with IC50 values, 22.2, 26.7 and 28.5 µM, respectively. Compound 9 was the most active of all the tested compounds against butyrylcholinesterase enzyme with an IC50 value of 36.3 µM.
NOVICE AND EXPERIENCED ENGLISH LANGUAGE TEACHERS’  TEACHING TECHNIQUES, CLASSROOM MANAGEMENT,  LESSON  PLANNING AND PRESENTATION SKILLS: THE CASE OF FIVE SELECTED  SECONDARY SCHOOLS OF WOLAITA ZONE
Creators: name: ELIAS JUTA
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The main purpose of this study was to investigate novice and experienced English language
teachers’ teaching techniques, classroom management, lesson  planning and presentation
skills. The design employed in the study was descriptive survey. The sampling technique used
in the study was comprehensive sampling technique. The sample size was 37 experienced
teachers and 15 novice teachers with the total of  52 participants involved in this study. The
data gathering instruments were  observation and questionnaire.  Questionnaire was
administered to 37 experienced and 15 novice teachers, and all 52 of them properly filled and
returned the questionnaire. Primary data were collected from observation and questionnaire.
The collected data were analyzed using  both qualitative and  quantitative methods of data
analysis. The study indicated that teaching techniques used by novice teachers in the study
area were  discussions;  pair work and lecture whereas experienced teachers highly used role
play, group work and drills as a teaching technique.  Findings of this study showed that
novice teachers have poor experience on managing misbehaving students, were not well
prepared to  maintain discipline in the classroom, had no ability to handle students’
individual differences in the classroom and had minimal plan of activities designed to involve
all students while maintaining discipline in the classroom. the findings of this study depicted
that experienced teachers had better understanding in writing clear lesson objectives, had the
capacity to plan instruction based on curricular goal, decide on steps necessary to teach the
lesson and had the ability to plan suitable assessment procedures for  learning procedures.  It
was recommended that experienced teachers should share their knowledge and experiences
to novice teachers about the use of teaching techniques. It was also recommended that the
Ministry of Education and other concerned bodies should organize successive workshops,
seminars and in-service trainings so that experienced teachers can get the chance to share
experiences to novice teachers on how to cope with the existing problems encountered in
teaching techniques in secondary schools.

The policing of biomarine resources in the Southern Ocean
Creators: name: Ash, John Stewart
Publisher: name: Apollo - University of Cambridge Repository
Year: 1994

description: The Southern Ocean constitutes some 22 % of the world ocean, and has some of the worst climatic conditions on the planet. Historically, marine biota have been one of the most important benefits derived from the Antarctic. The history of living resource utilisation in the region is a record of pillage, with market forces as the only constraint. Recently, this has changed, with the emergence of international agreements and public demand for conservation. The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) is unique both in the ecosystem approach it takes to the management of the fisheries and living resources, and in the lineage of the Antarctic Treaty System from which it stems. Despite its endeavours within the purview of treaty law, its greatest powers may derive from the coincidence of the richest fishing grounds and the Exclusive Economic Zones (EEZs) surrounding the peri-Antarctic islands possessed by member states. Despite the range of approaches available to address the problems of biomarine resource policing, no single approach emerges as a complete and cheap solution. The most promising surveillance technique is satellite remote sensing, utilising synthetic aperture radar. At present, the most economical existing technology for surveillance around the peri-Antarctic islands is light aircraft, and on the high seas, onboard inspectors representing CCAMLR interests. The most economical patrol vessels are likely to be those purchased outright as working vessels, and converted to government use.

description: In this work, we aim to take a detailed experimental picture of the positive streamer. We apply optical emission spectroscopy to the first negative system (FNS, ${\rm B}^2Σ_{\rm u}^+\rightarrow {\rm X}^2Σ_{\rm g}^+$) of N$_2^+$ and the second positive system (SPS, ${\rm C}^3Π_{\rm u}\rightarrow {\rm B}^3Π_{\rm g}$) of N$_2$. Large, centimeter wide, and highly reproducible streamers are created in pure nitrogen and synthetic air, at pressures ranging from 33 to 266\,mbar. Direct time resolved spectral imaging of the space charge layer resulted in spatiotemporal maps of the calculated reduced electric field strength ($E/N$) and rovibrational temperature in sub-nanosecond and sub-millimetre resolution. The $E/N$ peaks at approximately 540 and 480\,Td, directly in front of the space charge layer, for synthetic air and pure nitrogen respectively, as determined by using the intensity ratio method of FNS and SPS. A global model for pure nitrogen in PLASIMO uses the experimentally determined $E/N$ distribution to draw a picture of the gas kinetics around the space charge layer passage. In addition, the results of the global model serve as a reference to interpret the rotational and vibrational temperatures obtained from experimental FNS and SPS emissions, which emphasize the streamers' non-equilibrium gas heating.
