IMPACT OF URBAN EXPANSION ON THE LIVELIHOODS OF THE PERIPHERAL  COMMUNITY: A CASE STUDY FROM HOLETA TOWN, OROMIA, ETHIOPIA
Creators: name: ASMERA BEKELE INKI
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Holeta town’s expansion program which had been experiencing a horizontal expansion
starting from its historical expansion  pattern  currently  implemented  via  expropriating
peripheral land holders  of earlier rural dwellers  by  solely decision  of  town
administration and the investigation randomly targeted to per-urban areas like;  Galgal
Kuyu, Tullu Harbu and Burka Welmera   from five peripheral kebeles surrounding of
town. Rapid expansion of the town and in proportional expansion of town with community
livelihood is a serious issue for conducting research. Thus the  study investigated the
impact of urban  expansion on the peripheral community livelihood in case of Holeta
town. Questionnaire, survey, focus group discussion and key informants interviews were
tools of data collection from 313 sampled households  living in  sampled kebeles via
systematic random sampling technique and judgmental technique for FGD and interview.
The results of the study indicated that there is infrastructural improvement, socio
economic growth, rapid population growth and also socio-economic problems related to
urban expansion in studied area. There is great spatial and temporal land use land cover
modification more towards to build up land uses. The livelihood condition of per-urban
community changed to non-agricultural form but there are policy and strategy gaps of
expropriating, compensating for affected community in ground implementation.  The
dislocation program implemented is not rehabilitative and negatively affected the
livelihood of the dislocated farming community. Furthermore, the study revealed that
children losses right of family inheritance in town administration.   Landholder
expropriated should be recompensed for equal socio-economic  beneficially from
urbanization and further skill oriented training for new livelihood strategy and also
accessing credit and rehabilitating strategy were recommended for affected community
livelihood.

Tissue factor-related mechanisms of coagulation initiated on the virus envelope
Creators: name: Lin, Huan-Jih
Publisher: name: University of British Columbia
Year: 2019

description: Infectious diseases do not always manifest in a predictable manner and may go undetected, especially in asymptomatic individuals. Here, virus infection as an underlying cause of vascular disease is investigated. When considered independently, both have major impacts on healthcare systems globally. However, a relatively unexplored area of investigation is that many virus types have been tied to cardiovascular and haemostatic diseases. The mechanisms by which viruses accomplish this is not understood. As a model, I have used herpes simplex virus type 1 (HSV1) to explore the concept that viruses that obtain an outer phospholipid bilayer membrane can acquire the main physiological initiator of coagulation, tissue factor (TF). The Pryzdial lab has previously shown that several herpesviruses, including HSV1, incorporate TF when they are propagated in TF-expressing cells. TF is involved in the activation of the coagulation pro-enzyme factor X through the enhancement of factor VIIa proteolytic activity. This was shown to enhance virus infectivity through coagulation protease-dependent activation of cell signaling. HSV1 also expresses its self-encoded membrane protein, glycoprotein C (gC), which is involved in cell adhesion and immune escape. As gC is also capable of binding factor X, I postulated that gC regulates factor X activation through TF on the virus surface. To study how gC affects TF function, protein interactions were followed via cross-linking, chromogenic activity assays and microscale thermophoresis. In this study, I discovered that gC interacted with factor VIIa and factor X, rather than with TF, to form a unique enzyme complex that activates factor X. Similar to TF and factor VIIa interaction, gC requires factor X to efficiently assemble with factor VIIa. This complex can directly activate factor X and induce fibrin formation in plasma. Although this pro-coagulant function of gC may be restricted to homologous gene products in all herpesvirus family members, I have demonstrated that other viruses can incorporate TF into their membranes. In addition to purified viruses propagated in cell culture, I found that patient plasma-derived human immunodeficiency virus and hepatitis C virus can incorporate TF into their virus envelope. This could explain some of the haemostatic abnormalities associated with viral infection.
ASSESSMENT OF FARMERS’ PERCEPTION TO DEFORESTATION,  IN SODO WOREDA, GURAGE ZONE, SOUTH CENTRAL ETHIOPIA

Year: 2018

description: Deforestation in Ethiopia  is  remained  increasingly at alarming rate and the rate of
afforestation was  not  adequately  equal  with  high rate of clearing  forest resources  for
different purposes.  This study was aimed at  assessing  farmer’s  perception  to
deforestation, and its causes and consequences in Sodo-Woreda (Gurage zone) based on
the perception of  households.  The study was based on descriptive  survey and followed
cross sectional design encompassing both qualitative and quantitative data. A total of 192
sample respondents were selected through systematic random sampling. The data were
analysed by using simple descriptive statistics such as percentage, frequency, tables and
charts. Qualitative data were  analysed  through interpretation and conceptual
generalization. Result of the study showed that deforestation is not only a real threat but
it  is also a critical problem in Soddo  Woreda  (Gurage-  Zone).  Poverty  is a major
determinant of the way in which people make decisions about resource use. In the study
area human induced mismanagement of natural resource is a root cause of forest
degradation together with concomitant climate changes. Unwise utilization of natural
resources such as forest basically implies the risk of over using and degrading these
resources in the area. Factors such as production of fire wood and charcoal, expansion
of crop farming, exploitation of forest for construction  materials (ex. timber) over-
browsing and over grazing, and settlement, infrastructure and urban expansion were the
main direct cause of deforestation problem in the study area underlain by growing
population and  poverty. Results  of the study also indicated that, increasing local
temperature and soil erosion, drought, shortage of forest products, loss of bio-diversity
(plant and animal species), etc., were the major negative effects of deforestation problem
in the study area. Therefore,  the woreda agriculture and rural development offices and
every concerned stakeholder  should be a promotion of environmental education and
awareness, and the  expansion  of alternative energy  sources, training, fuel saving
technology, diffusion should be facilitated in order to reduce their dependency on fuel
wood.

description: We present a high-cadence multi-epoch analysis of dramatic variability of three broad emission lines (MgII, H$β$, and H$α$) in the spectra of the luminous quasar ($λL_λ$(5100Å) = $4.7 \times 10^{44}$ erg s$^{-1}$) SDSS J141041.25+531849.0 at $z = 0.359$ with 127 spectroscopic epochs over 9 years of monitoring (2013-2022). We observe anti-correlations between the broad emission-line widths and flux in all three emission lines, indicating that all three broad emission lines "breathe" in response to stochastic continuum variations. We also observe dramatic radial velocity shifts in all three broad emission lines, ranging from $Δ{v}$ $\sim$400 km s$^{-1}$ to $\sim$800 km s$^{-1}$, that vary over the course of the monitoring period. Our preferred explanation for the broad-line variability is complex kinematics in the broad-line region gas. We suggest a model for the broad-line variability that includes a combination of gas inflow with a radial gradient, an azimuthal asymmetry (e.g., a hot spot), superimposed on the stochastic flux-driven changes to the optimal emission region ("line breathing"). Similar instances of line-profile variability due to complex gas kinematics around quasars are likely to represent an important source of false positives in radial velocity searches for binary black holes, which typically lack the kind of high-cadence data we analyze here. The long-duration, wide-field, and many-epoch spectroscopic monitoring of SDSS-V BHM-RM provides an excellent opportunity for identifying and characterizing broad emission-line variability, and the inferred nature of the inner gas environment, of luminous quasars.
SMALL-SCALE CATTLE FARMING IN DENDI WOREDA, OROMIA REGION,  ETHIOPIA
Creators: name: MITIKU LELISA AMENTE
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The  objective  of  this  study  is  to  identify  the  socio-economic  and  environmental  factors
affecting small-scale cattle farming in Dendi  Woreda, West Shewa Zone, Central Ethiopia.
To do so, firstly the study Woreda was stratified by agro-ecology into two (Dega and WoinaDega).  Secondly,  three  rural  kebeles  namely  Dano  Ejersa  Gibe,  Golole  Bolo  and  Galesa
Koftu were selected using lottery method from Woina-Dega and Dega agro-ecological zone
respectively.   Thirdly,  300  sample  respondents  were  selected  by  using  random  sampling
techniques  from  selected  kebeles  including  both  male  and  female  headed  households.  To
achieve the objective, the researcher used a survey design. The primary data were collected
through questionnaire, semi-structured  interview, and  observation from the field. To  support
the primary data, secondary data also collected from different documents and studies and all
were  analyzed  qualitatively.  Simple  statistical  descriptions  like  frequency  and  percentages
were employed with the aid of Statistical Packages for Social Studies for analyzing
and interpreting the data collected. The analysis of the study was also supplemented with
visual  photographs  recorded  during  field  observation.  From  the  findings  of  the  study  it  is
simple to conclude that, Dendi Woreda has various livestock resource that played a vital role
for economic development.  However, this sector has not grown significantly when compared
to the cattle resource of the Woreda. The finding also indicates that a cattle farming in Dendi
Woreda has several constraints.  The constraints of cattle rearing system were feed shortage,
water  impurity,  diseases  and  parasites  particularly  tick  (silmi),  shortage  of  grazing  land,
veterinary  services  and  extension  services.  Therefore,  more  emphasis  should  be  given  to
improving cattle productivity through strong extension services in proper management of the
grazing lands, feed conservation, crop residues treatment and healthcare provision. Based
on the findings, the study forwards some suggestions and recommendations for  researchers,
policy makers and development practitioners for future action.
THE  SOCIO-ECONOMIC  and Environmental  ROLE  OF  ENSET  (ENSET  VENTRICOSUM) IN CHEHA WEREDA, GURAGE ZONE, SOUTHERN ETHIOPIA
Creators: name: TANE BESIR YIRORGA
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Enset (Ensete ventricosum ) is a multipurpose indigenous crop in Ethiopia. The
cultivation of enset is a central farming activity due to its various social, economic and
environmental significances for farm households. The main objective of this research was
to assess the socio-economic and environmental roles of enset in Cheha wereda,
southwestern Ethiopia. To meet the objectives, qualitative  research approaches was
employed. To determine the size of sample kebeles, random sampling technique  was
utilized. In this case, 278  sample households were selected from three  kebeles. To
supplement and bridge household survey data, focus group discussion, key informant
interview and field observation were undertaken. Data were analyzed by and qualitative
methods, using simple descriptive statistics, frequency, percentage, tables, graphs and
photographs. The findings show that enset plays a vital role in the socio-economic life of
the people in the study area. In line with this, farm households consider that enset is a
cultural identity crop, an indication of status symbol, as a medicinal purpose, primary
source of food for farm households and source of livestock feed. Its complex spongy root
system form mate-like structure in the root zones and its leaf canopy enabled an excellent
mechanism for protecting soil against erosion, runoff and land degradation, conserve soil
and moisture and increase soil fertility. Furthermore, it is drought tolerant as compared
to root or tuber crops. Based on this research finding the major constraints that hinder
the role of enset identified by farmers were disease and lack of  disease controlling
measures for enset disease and lack of modern technology. Moreover, the attention given
by concerned bodies (government, NGOs and research organizations) to improve the
productivity of enset is low. Hence, this research recommends that its sustainability needs
close attention from research institutions, government and non-government organizations
working in the area.

description: Despite extensive search efforts, direct observations of the first (Pop III) stars have not yet succeeded. Theoretical studies have suggested that late Pop III star formation is still possible in pristine clouds of high-mass galaxies, coexisting with Pop II stars, down to the Epoch of Reionization (EoR). Here we reassess this finding by exploring Pop III star formation in six $50h^{-1} ~$cMpc simulations performed with the hydrodynamical code dustyGadget. We find that Pop III star formation ($\sim 10^{-3.4} - 10^{-3.2} ~ \mathrm{M_\odot yr^{-1} cMpc^{-3}}$) is still occurring down to $z \sim 6 - 8$, i.e. well within the reach of deep JWST surveys. At these epochs, $\gtrsim 10 \%$ of the rare massive galaxies with $M_\star \gtrsim 3 \times 10^9 ~ \mathrm{M_\odot}$ are found to host Pop III stars, although with a Pop III/Pop II mass fraction $\lesssim 0.1 \%$. Regardless of their mass, Pop III hosting galaxies are mainly found on the main sequence, at high star formation rates, probably induced by accretion of pristine gas. This scenario is also supported by their increasing star formation histories and their preferential location in high-density regions of the cosmic web. Pop III stars are found both in the outskirts of metal-enriched regions and in isolated, pristine clouds. In the latter case, their signal may be less contaminated by Pop IIs, although its detectability will strongly depend on the specific line-of-sight to the source, due to the complex morphology of the host galaxy and its highly inhomogeneous dust distribution.

study area was selected purposively and the data from 285 sample households were collected
in the three rural kebeles, which were selected by considering agro-ecological zones,  from
each agro-ecological  zone, the  kebeles were selected by using stratified random sampling
method.  Survey  was conducted to collect primary data that were gathered  by using
structured household  questionnaire, focus group discussions,  and key  informant interview
and field observations. Descriptive statistics were used to characterize  the farming in terms
of their socio-economic and demographic back ground,. The role of crops in the integrated
farming was source of feed for livestock, medicinal, utilization of resources and reducing the

improve productivity of crops and animal products that can easily tap into organic
production. A clear evidence of wide spread interest to experience the practice with strong
positive perception. Constraints to integrating crops and livestock include the competition
for resources,  especially  land, managing  two types of farming on the same farm was
perceived as difficulty  and low Extension  services.  The  farmers were facing challenges in

description: Jets are a ubiquitous phenomenon in all classes of accreting stellar-mass compact objects; white dwarfs, neutron stars, and black holes. While jet production appears to be fundamentally related to the process of accretion, the exact nature of the coupling between the accretion flow and jets remains to be determined. In this talk, I will introduce and review our current understanding of the connection between the accretion inflow and jet outflows during an outburst. In particular, I will focus on this relationship around and during X-ray state transitions, with a discussion on what we can learn about jet launching from the observations. I will also briefly discuss what the immediate future holds for accretion-ejection studies of X-ray binaries.

description: Abstract
Resettlement program is one of the development strategy designed and implemented by the
existing government in Ethiopia. Gechi Woreda is one of Woreda in Ilu Aba Bora Zone in
Oromia Regional State, in which resettlement program was undertaken to improve the living
conditions of the settlers. The study was conducted to assess Contribution of Resettlement on
the  Livelihood Improvement in Gechi Woreda, at Chate Resettlement Site. To convey
information, both primary and secondary data were used. A total of 171 sample respondents
were sampled to fill questionnaires by using simple random sampling technique and
interviewees were purposely selected from concerned bodies those have detail ideas on the
issue. The collected data were analyzed using frequency, percentages and mean and finally
each data were interpreted qualitatively. All settlers were voluntarily settled, 56.2% of the
populations are educated, 76.02% and 45.6% were respectively used firewood and animal
residuals before resettlement where 58.47%, 52.63%, and 23.39% were users of firewood,
animal residuals and solar energy respectively after resettlement. It was found that, 88.3% of
the respondents had access to credit service after resettlement, 67.3% of population in the
study areas were living in house made of mud walls and tin roofed, 56.1% were users of
hand water pump, mean land holding of settlers were 2.91 hectares per household, the
average income of the settlers reached 3564.80 in birr per month after the program and
mean production per hectare on the basis of before resettlement was 8.83 quintal per hectare
after resettlement.  Finally recommendations were given: family size of the settlers should be
in consideration by the stakeholders, relationship among settlers and local communities
should be encouraged, the efforts of the government bodies and families are must in order to
increase educational level of settlers, adopting different types of livelihood strategies, use of
different ways of savings should be cultured.
Gate-controlled Magnetotransport and Electrostatic Modulation of Magnetism in 2D magnetic semiconductor CrPS$_4$

description: Using field-effect transistors (FETs) to explore atomically thin magnetic semiconductors with transport measurements is difficult, because the very narrow bands of most 2D magnetic semiconductors cause carrier localization, preventing transistor operation. Here, we show that exfoliated layers of CrPS$_4$ -- a 2D layered antiferromagnetic semiconductor whose bandwidth approaches 1 eV -- allow the realization of FETs that operate properly down to cryogenic temperature. Using these devices, we perform conductance measurements as a function of temperature and magnetic field, to determine the full magnetic phase diagram, which includes a spin-flop and a spin-flip phase. We find that the magnetoconductance depends strongly on gate voltage, reaching values as high as 5000 % near the threshold for electron conduction. The gate voltage also allows the magnetic states to be tuned, despite the relatively large thickness of the CrPS$_4$ multilayers employed in our study. Our results show the need to employ 2D magnetic semiconductors with sufficiently large bandwidth to realize properly functioning transistors, and identify a candidate material to realize a fully gate-tunable half-metallic conductor.

description: The charge-exchange spin-dipole (SD) excitations of 208Pb are studied by using a fully self-consistent Skyrme Hartree-Fock plus Random Phase Approximation (HF+RPA) formalism which includes the tensor interaction. It is found, for the first time, that the tensor correlations have a unique, multipole-dependent effect on the SD excitations, that is, they produce softening of 1- states, but hardening of 0- and 2- states. This paves the way to a clear assessment of the strength of the tensor terms. We compare our results with a recent measurement, showing that our choice of tensor terms improves the agreement with experiment. The robustness of our results is supported by the analytic form of the tensor matrix elements.

description: The stellar activity of M dwarfs is the main limitation for discovering and characterizing exoplanets orbiting them since it induces quasi-periodic RV variations. We aim to characterize the magnetic field and stellar activity of the early, moderately active, M dwarf Gl205 in the optical and nIR domains. We obtained high-precision quasi-simultaneous spectra in the optical and nIR with the SOPHIE spectrograph and SPIRou spectropolarimeter between 2019 and 2022. We computed the RVs from both instruments and the SPIRou Stokes V profiles. We used ZDI to map the large-scale magnetic field over the time span of the observations. We studied the temporal behavior of optical and nIR RVs and activity indicators with the Lomb-Scargle periodogram and a quasi-periodic GP regression. In the nIR, we studied the equivalent width of Al I, Ti I, K I, Fe I, and He I. We modeled the activity-induced RV jitter using a multi-dimensional GP regression with activity indicators as ancillary time series. The optical and nIR RVs have similar scatter but nIR shows a more complex temporal evolution. We observe an evolution of the magnetic field topology from a poloidal dipolar field in 2019 to a dominantly toroidal field in 2022. We measured a stellar rotation period of Prot=34.4$\pm$0.5 d in the longitudinal magnetic field. Using ZDI we measure the amount of latitudinal differential rotation (DR) shearing the stellar surface yielding rotation periods of Peq=32.0$\pm$1.8 d at the stellar equator and Ppol=45.5$\pm$0.3 d at the poles. We observed inconsistencies in the activity indicators' periodicities that could be explained by these DR values. The multi-dimensional GP modeling yields an RMS of the RV residuals down to the noise level of 3 m/s for both instruments, using as ancillary time series H$α$ and the BIS in the optical, and the FWHM in the nIR.

description: We investigate lattice Weinberg - Salam model without fermions numerically for the realistic choice of coupling constants correspondent to the value of the Weinberg angle $θ_W \sim 30^o$, and bare fine structure constant around $α\sim 1/150$. We consider the values of the scalar self coupling corresponding to Higgs mass $M_H \sim 100, 150, 270$ GeV. It has been found that nonperturbative effects become important while approaching continuum physics within the lattice model. When the ultraviolet cutoff $Λ= \fracπ{a}$ (where $a$ is the lattice spacing) is increased and achieves the value around 1 TeV one encounters the fluctuational region (on the phase diagram of the lattice model), where the fluctuations of the scalar field become strong. The classical Nambu monopole can be considered as an embryo of the unphysical symmetric phase within the physical phase. In the fluctuational region quantum Nambu monopoles are dense and, therefore, the use of the perturbation expansion around trivial vacuum in this region is limited. Further increase of the cutoff is accompanied by a transition to the region of the phase diagram, where the scalar field is not condensed (this happens at the value of $Λ$ around 1.4 TeV for the considered lattice sizes). Within this region further increase of the cutoff is possible although we do not observe this in details due to the strong fluctuations of the gauge boson correlator. Both mentioned above regions look unphysical. Therefore we come to the conclusion that the maximal value of the cutoff admitted within lattice Electroweak theory cannot exceed the value of the order of 1 TeV.

description: Semiflexible slender filaments are ubiquitous in nature and cell biology, including in the cytoskeleton, where reorganization of actin filaments allows the cell to move and divide. Most methods for simulating semiflexible inextensible fibers/polymers are based on discrete (bead-link or blob-link) models, which become prohibitively expensive in the slender limit when hydrodynamics is accounted for. In this paper, we develop a novel coarse-grained approach for simulating fluctuating slender filaments with hydrodynamic interactions. Our approach is tailored to relatively stiff fibers whose persistence length is comparable to or larger than their length, and is based on three major contributions. First, we discretize the filament centerline using a coarse non-uniform Chebyshev grid, on which we formulate a discrete constrained Gibbs-Boltzmann equilibrium distribution and overdamped Langevin equation. Second, we define the hydrodynamic mobility at each point on the filament as an integral of the Rotne-Prager-Yamakawa kernel along the centerline, and apply a spectrally-accurate quadrature to accurately resolve the hydrodynamics. Third, we propose a novel midpoint temporal integrator which can correctly capture the Ito drift terms that arise in the overdamped Langevin equation. We verify that the equilibrium distribution for the Chebyshev grid is a good approximation of the blob-link one, and that our temporal integrator samples the equilibrium distribution for sufficiently small time steps. We also study the dynamics of relaxation of an initially straight filament, and find that as few as 12 Chebyshev nodes provides a good approximation to the dynamics while allowing a time step size two orders of magnitude larger than a resolved blob-link simulation. We conclude by studying how bending fluctuations aid the process of bundling in cross-linked networks of semiflexible fibers.

description: We study a device formed by a Bose Einstein condensate (BEC) coupled to the field of a cavity with a moving end-mirror and find a working point such that the mirror-light entanglement is reproduced by the BEC-light quantum correlations. This provides an experimentally viable tool for inferring mirror-light entanglement with only a limited set of assumptions. We prove the existence of tripartite entanglement in the hybrid device, persisting up to temperatures of a few milli-Kelvin, and discuss a scheme to detect it.

description: The W boson can obtain a small right-handed coupling to quarks and leptons through mixing with a hypothetical W' boson that appears in many extensions of the Standard Model. Measuring or even bounding this coupling to the light quarks is very challenging. Only one model independent bound on the absolute value of the complex mixing parameter has been obtained to date. Here we discuss a method sensitive to both the real and CP-violating imaginary parts of the coupling, independent of assumptions on the new physics, and demonstrate quantitatively the feasibility of its measurement at RHIC.

description: The  practices  of FGM are  a trans-generational problem across the world. It is a
national problem and a sensitive cultural issue in Ethiopia. It affects the live of girls
and women in the country. The objective of the study is to assess community‟s
perception toward the  practices of FGM in wonchi district. The researcher used
mixed research approach and triangulation design for the study. Data source for the
study were generated from primary and secondary data sources. By using simple
random sampling three kebeles were selected from 26 kebeles of the study woreda
and 285-sample household heads were selected from 998 total household heads. The
data for the study were collected through questionnaire, interview and focus group
discussion. Quantitative data were analyzed by using table, frequency and
percentage. While, qualitative data were analyzed in description form by using
words. The findings of the study from both quantitative and qualitative information
revealed that all community do not have similar perception on harmfulness of FGM.
Underlying  reasons that forced community to practices FGM are: culturally
uncircumcised girl is not get husband in the community. Similarly, there is
discrimination and insult against  uncircumcised girl in the community.  The main
reasons for  the continued practices of FGM in the community includes FGM is very
much intertwined with long held  cultural beliefs and social norms within the
community, and  the  existing laws against FGM is not put in to practice effectively.
Based on the findings the  following recommendations were suggested. Government
should strengthen public awareness on harmfulness of FGM, and mobilize all
educational institutions and media to change negative attitudes and customary action
towards women and children.  Similarly, community should collaborate with local
authorities and other institutions to learn, teach, and take violators to legal bodies.

description: Our theory holds that the ultra-high pressure inside the sun produces high-energy neutrinos, and high-energy neutrinos produce a variety of secondary particles in the solar atmosphere to form solar cosmic rays. There is a gamma ray experiment and two AMS-01 experiments to support our theory; one is the anomalous positron-electron ratio near the equator in the AMS-01 experiment, and the other is the helium-3 distribution near the equator in the AMS-01 experiment.
Craniofacial differences between obese and non-obese orthodontic patients

description: Introduction: Although childhood obesity has recently seen a plateau in the USA and Canada, it still effects 10-20% of children and adolescents. Increasing evidence points to obesity contributing to changes in growth and development, puberty, bone metabolism and tooth movement. For this study, we compared craniofacial differences in obese and non-obese orthodontic patients between the ages of 7-16 years old, focusing on a younger age cohort than studied previously. Objectives: To evaluate the craniofacial form of obese and non-obese adolescent patients using 2D cephalometric data and geometric morphometric approaches. Methods: Height, weight, age, and lateral cephalometric radiographs were gathered from patients aged 7-16, before beginning orthodontic treatment at the University of British Columbia (UBC). A group of 24 obese patients were age, sex and Angle-classification of malocclusion matched, with non-obese controls. Cephalometric radiographs were annotated, and coordinates of landmarks used to obtain traditional linear and angular measurements. Additionally, geometric morphometric (GM) analyses was performed to determine overall craniofacial form. Dental maturation index scores were assessed from panoramic films using the Demerijian method and cervical vertebral maturation (CVM) scores were recorded from the cephalograms, as an indicator for skeletal maturation. Results: Our conventional cephalometric analysis revealed that the maxillary length and gonial angle are larger in obese individuals (p=0.041 and p=0.028 respectively). GM analyses confirmed that the overall craniofacial form of obese patients differs statistically from the form of control patients and also reveal that obese patients present with a more dolichocephalic facial type. Dental maturation index scores were statistically higher in the obese group compared to the control group with no statistical difference in CVM scores. Conclusions: Our data reveals a subtle but significant difference in cranial skeletal morphology between obese and non-obese adolescent patients, suggesting a correlation between dental maturation, craniofacial form and physiologic/metabolic phenotypes of individuals. Body Mass Index should be included as part of the orthodontic assessment to aid in appropriate diagnosis of the underlying craniofacial form.

description: Superconducting magnet training is one of the accelerator related issues attracting attention due to significant operational costs and time budget associated to it. It is especially worrisome that magnets based on the next-generation Nb3Sn technology are affected by long training. While various efforts are underway to better understand and resolve the problem a parallel path could also be investigated, a path bypassing the issue. Following the concept of fast induced over-current during magnet powering, FNAL has developed an upgradable capacitor-based device to discharge through a superconducting magnet at quench detection or operator chosen time. The 0.4 F/1 kV device has been tested on a 1-m-long dipole-coil in a mirror magnet configuration and conclusive results on magnet training elimination have been observed. In this paper we discuss the main characteristics of the device, compare simulated response and actual performance, elaborate on test drivers and outcomes. Next steps and perspectives for future use are debated.

description: The time-space evolution of the field is described by the transport equation for the 2-dimensional wave energy spectrum density, S(x,t), spread in the space, x, and time, t. This equation has the forcing named the source function, F, depending on both the wave spectrum, S, and the external wave-making factors: local wind, W(x, t), and local current, U(x, t). The source function contains certain physical mechanisms responsible for a wave spectrum evolution. It is used to distinguish three terms in function F: the wind-wave energy exchange mechanism, In; the energy conservative mechanism of nonlinear wave-wave interactions, Nl; and the wave energy loss mechanism, Dis. Differences in mathematical representation of the source function terms determine general differences between wave models. The problem is to derive analytical representations for the source function terms said above from the fundamental wave equations. Basing on publications of numerous authors and on the last two decades studies of the author, the optimized versions of the all principal terms for the source function, F, have been constructed. Detailed description of these results is presented. The final version of the source function is tested in academic test tasks and verified by implementing it into numerical shells of the well known wind wave models: WAM and WAVEWATCH. Procedures of testing and verification are presented and described in details. The superiority of the proposed new source function in accuracy and speed of calculations is shown. Finally, the directions of future developments in this topic are proposed, and some possible applications of numerical wind wave models are shown, aimed to study both the wind wave physics and global wind-wave variability at the climate scale, including mechanical energy exchange between wind, waves, and upper water layer.
