description: The aim was to assess the impact of the COVID-19 pandemic on French Poison Control Centre (PCC) call characteristics. Reported cases of xenobiotic exposures from 1 March to 30 April in 2018, 2019, and 2020 were extracted from the French National Database of Poisonings. The collected data included call, patient, and exposure characteristics for both general calls and for calls involving sentinel xenobiotic categories related to the COVID-19 pandemic. The 2020 exposures were compared to 2018–2019 exposures by using simple logistic models in order to provide effect size with odds ratios. From March to April 2020, 32,182 exposures were reported to French PCCs with an overall increase of 5.6% compared to exposures in the same time frame in 2018–2019. A similar increase in calls was observed in non-epidemic and epidemic COVID-19 areas with an increase in calls from the public (+13.6%) while calls from health-professionals decreased (−7.5%). Despite the increase in exposures, the incidence of symptomatic exposures remained stable (−0.4%) with a decrease in severity (moderate/severe −17.2%). A significant increase in exposures to home cleaning products containing biocides, essential oils, and alcohol-based hand sanitizers (odds ratio >1.3, p The COVID-19 pandemic altered calls to French PCCs with a small increase in calls during the study period and changes in the pattern of exposure. These changes possibly reflected the indirect consequences of the COVID-19 pandemic i.e., limited access to primary care, fear of contracting COVID-19 and anxiety related to home isolation.

description: Onion crop is one of the most important vegetables produced in Ethiopia for both commercial and consumption purposes. However, due to different constraints the potential of the crop was not utilized to the fullest extent by economic entities along the commodity chain. Thus, the study was conducted in order to assess the opportunities, constraints and to develop strategic interventions in onion production and value chain in Ambo and Toke Kutaye districts of West Showa Zone, Oromia Regional State, Ethiopia in the year 2015 with the objective of identifying the constraints and opportunities for onion value chain functions in the study areas. From the districts, seven onion producing kebeles were selected randomly and the data were collected from both primary and secondary sources. The primary data were collected using interview guided questionnaires from 183 respondents’ of different actors in onion value chain and four focus group discussions of onion producers. Descriptive statistics and value chain analysis were used to analyze the constraints and opportunities data. Onion value chain in the area contains different actors at the stages of input suppliers, onion producers, wholesalers, retailers and consumers. Thus, diseases, drought, insects, lack of sufficient irrigation water, limited supply of agricultural inputs, limited knowhow and skill, low price of produce and poor linkage with value chain actors were major producers’ constraints identified in the study areas. Supply shortage, lack of organized market information, low produce quality, loss of produce due to poor handling, competition with unlicensed traders, price fluctuation and lack of support from government bodies were major marketing constraints studied on the traders. Thus, onion value chain is affected by several aforementioned constraints at each stage of the chain functions those influenced the efficiency and competitiveness of the whole chain in the study areas. The recommendations forwarded to accelerate the onion value chain’s development are strengthening extension system and other supportive services; supporting producers in order to use improved agricultural inputs, modern technologies, controlling diseases and insects (pests) problems; constructing additional irrigation facilities/schemes; organizing, strengthening and supporting vegetable producer cooperatives and controlling unlicensed traders.

description: Background: Globally, HIV and tuberculosis (TB) are a leading cause of death if they occur as co morbidities in affected individuals. The aim of this study was to evaluate the collaboration between TB and HIV control activities by determining the co-morbidity rate in Oromia Region, Ethiopia, during the period 2009–2015. Methods: A retrospective health facility-based study was conducted. Data were collected from health facilities implementing the directly observed treatment short-course (DOTS) strategy in the region. A structured World Health Organization (WHO) reporting format was used as the data collection tool. Pre antiretroviral therapy (ART)/voluntary counselling and testing for HIV (VCT) and TB unit registers were considered as the data sources. Data were collected quarterly and analyzed using IBM SPSS Statistics version 20. The odds ratio was used to assess statistical differences among variables. Results: A total of 115 268 TB patients were counselled and tested for HIV during the study period. Among the patients tested, 60 086 (52.1%) were male, of whom 13 680 (11.8%) were found to have an HIV infection. Among TB patients who were co-infected with HIV, there were slightly higher odds of HIV infection in females than in males (odds ratio 1.13, 95% conﬁdence interval 1.09–1.17). Between 2009 and 2013, about 56% of TB and HIV co-morbid patients were put on co-trimoxazole preventive therapy (CPT) and 35% on ART. HIV infection occurred predominantly within the age group of 25–34 years (31%). On the other hand, 197 152 HIV-infected patients were screened for TB symptoms and 8.4% were found to have active TB. The odds of having TB among males who were initially infected with HIV were higher as compared to females (odds ratio 1.31, 95% conﬁdence interval 1.27–1.37). Conclusions: The prevalence of TB and HIV co-morbidity was 11.8% at TB clinics in the region. Low proportions of co-infected patients were put on CPT and ART. Therefore, it is essential to strengthen the WHO recommended TB and HIV collaborative activities in the region to reduce the burden of co morbidity and mortality. © 2018 The Author(s).

description: Understanding the principles of real-world biological multi-agent behaviors is a current challenge in various scientific and engineering fields. The rules regarding the real-world biological multi-agent behaviors such as team sports are often largely unknown due to their inherently higher-order interactions, cognition, and body dynamics. Estimation of the rules from data, i.e., data-driven approaches such as machine learning, provides an effective way for the analysis of such behaviors. Although most data-driven models have non-linear structures and high prediction performances, it is sometimes hard to interpret them. This survey focuses on data-driven analysis for quantitative understanding of invasion team sports behaviors such as basketball and football, and introduces two main approaches for understanding such multi-agent behaviors: (1) extracting easily interpretable features or rules from data and (2) generating and controlling behaviors in visually-understandable ways. The first approach involves the visualization of learned representations and the extraction of mathematical structures behind the behaviors. The second approach can be used to test hypotheses by simulating and controlling future and counterfactual behaviors. Lastly, the potential practical applications of extracted rules, features, and generated behaviors are discussed. These approaches can contribute to a better understanding of multi-agent behaviors in the real world.

description: Blepharitis is a chronic eye infection affecting the eyelid commonly result from exacerbation of normal microbial flora on the skin and occasionally due to meibomian gland dysfunction. Aim: Identifying organisms responsible for blepharitis with a view to enhancing its management. Method: Investigations of these patients were carried out with the use of slit lamp biomicroscopy after recording their habitual visual acuity. Patients were initially screened out at the GP department before eye examination. Samples were collected with swaps and pure strains were isolated. Samples’ DNA were extracted and amplified through polymerase chain reaction before sequencing. Result: Various strain of Staphylococcal organisms and Pseudomonas aeruginosa were the common organisms identified by 16S rRNA sequencing. Susceptibility tests were performed with most of the organisms found to be insensitive to the antibiotics tested. Conclusion: Blepharitis is known as one of the anterior ocular infection often encountered in clinical practice. It has been noted that clinical presentation does not provide enough diagnostic evidence in management thereby prompting the need for further microbial analysis. Proper identification of causative organisms with the help of more sophisticated and enhanced technique of molecular identification is believed to proffer better outcome in clinical practice.

description: Motivated by the severity of the bounds on Lorentz violation in the presence of ordinary gravity, we study frameworks in which Lorentz violation does not affect the spacetime geometry. We show that there are at least two inequivalent classes of spontaneous Lorentz breaking that even in the presence of gravity result in Minkowski space. The first one generically corresponds to the condensation of tensor fields with tachyonic mass which in turn is related to ghost-condensation. In the second class, realized by the DGP model or theories of massive gravitons, spontaneous Lorentz breaking is induced by the expectation value of sources. The generalization to de-Sitter space is also discussed.

description: Even though natural resources have a certain contribution for development of tourism in Ethiopia with its major contribution to livelihoods of the majority of Ethiopians, large of attractive natural and cultural resources are exposed to degradations or threats due to negligence (EPA, 1997). Therefore, the main objective of this study was assessing Ecotourism Development or alternative options for sustainable use of natural resources which will improve the livelihood of local communities and conservation of SSHS. To this end, the research has attempted to integrate both qualitative and quantitative approaches. Questionnaire, Key informant interview, Focused group discussion, direct observation and literature reviews were employed as instruments of data collection. The participants of the study were members of the local community, community leaders (Aba Geda), and related stakeholders like Agriculture and Rural Development office, Cultural and Tourism office, SSHS experts and Small and Micro enterprise office at woreda administration level. Four Kebeles were selected purposefully from 8 Kebeles which were surrounding the Sanctuary. The collected data using households’ survey were analyzed by frequency and Percentage. The findings showed that SSHS and the surrounding community have an excellent opportunity to develop ecotourism as an alternative livelihood. The analyses of the study revealed that natural and cultural resources such as abundance and diversity of bird, mammals, scenic landscape, hot springs, natural caves, waterfall and attractive vegetations are the main ecotourism potential in SSHS. Other opportunities include favorable weather conditions, local institutions and policy. So, developing ecotourism can engage a wide cross section of people and it is the most promising strategy to reduce the sever livelihood and diversify local livelihood options. However, at current time major constraints keep the potential opportunities from being developed. These include: lack of adequate infrastructure, lack of local community involvement and participation and unsustainable livelihood, inter-ethnic conflict, natural resource exploitation and lack of trained manpower. Thus, it is a crucial time for developing ecotourism to protect the beauty and environmental quality of the area and to improve local livelihood. In light of those circumstances, I strongly recommend all the concerned bodies to focus on the significance of developing ecotourism in the SSHS and the surrounding area. Keywords: Ecotourism, attractions, conservation, livelihood, Senkele Swayne’s Hartebeest Sanctuary, Protected area.

description: One possibility for identifying the inflaton in the framework of string theory is that it is a $D$-brane modulus. This option involves a specific, non-canonical form of the kinetic energy -- the Dirac-Born-Infeld action. This note investigates the applicability of the slow roll approximation in inflationary models of this type. To this end the slow roll expansion of Liddle, Parsons and Barrow is derived for the case of the DBI action. The resulting slow roll conditions augment the standard ones valid in the case of canonical kinetic terms. It is also shown that in DBI models inflation does not require that the potential dominate the energy density.

description: In the framework of the Einstein-Maxwell-axion-aether theory we establish the model, the Lagrangian of which contains the sin-type generalization of the term describing the axion-photon coupling, and the axionically induced cosine-type modification of the term attributed to the dilaton-photon interactions. The extension of the axion-dilaton-aether electrodynamics is inspired by the Jackson's idea concerning the internal symmetry of the equations of electromagnetism. The application of the extended theory to the anisotropic homogeneous cosmological model of the Bianchi-I type is considered. The exact solutions to the model evolutionary equations are obtained for the case, when the axionic dark matter is in the state of equilibrium, which is characterized by vanishing potential of the pseudoscalar field and its first derivative. The state of the axion-photon system, which is of a new type and is indicated as a dynamic equilibrium, is studied in the framework of electrodynamics with axionic non-linearity. We show that the nonlinear axion-photon interactions can mimic the dilaton-photon coupling. We discuss the stability of the model with respect to homogeneous fluctuations of the axion field.

description: We propose and experimentally demonstrate a single-mode fiber length and dispersion measurement system based on a novel frequency-shifted asymmetric Sagnac interferometer incorporating an acousto-optic modulator (AOM). By sweeping the driving frequency of the AOM, which is asymmetrically placed in the Sagnac loop, the optical length of the fiber can be determined by measuring the corresponding variation in the phase delay between the two counter-propagating light beams. Combined with a high-resolution data processing algorithm, this system yields a dynamic range from a few centimeters to 60km (limited only by our availability of long fibers) with a resolution about 1ppm for long fibers.

description: We construct a class of nuclear equations of state based on a schematic potential model, that originates from the work of Prakash et. al. \cite{Prakash-88}, which reproduce the results of most microscopic calculations. The equations of state are used as input for solving the Tolman-Oppenheimer-Volkov equations for corresponding neutron stars. The potential part contribution of the symmetry energy to the total energy is parameterized in a generalized form both for low and high values of the baryon density. Special attention is devoted to the construction of the symmetry energy in order to reproduce the results of most microscopic calculations of dense nuclear matter. The obtained nuclear equations of state are applied for the systematic study of the global properties of a neutron star (masses, radii and composition). The calculated masses and radii of the neutron stars are plotted as a function of the potential part parameters of the symmetry energy. A linear relation between these parameters, the radius and the maximum mass of the neutron star is obtained. In addition, a linear relation between the radius and the derivative of the symmetry energy near the saturation density is found. We also address on the problem of the existence of correlation between the pressure near the saturation density and the radius.

description: We describe a pulsed multi-frequency electron paramagnetic resonance spectrometer operating at several frequencies in the range of 110-336 GHz. The microwave source at all frequencies consists of a multiplier chain starting from a solid state synthesizer in the 12-15 GHz range. A fast PIN-switch at the base frequency creates the pulses. At all frequencies a Fabry-Perot resonator is employed and the pi/2 pulse length ranges from ~100 ns at 110 GHz to ~600 ns at 334 GHz. Measurements of a single crystal containing dilute Mn2+ impurities at 12 T illustrate the effects of large electron spin polarizations. The capabilities also allow for pulsed electron nuclear double resonance experiments as demonstrated by Mims ENDOR of 39K nuclei in Cr:K3NbO8.

Publisher: name: University of British Columbia

description: This study examines the concept of entrepreneurship as it relates to the culture and purpose of the university. An integrative review is employed to examine literature covering entrepreneurial theory, academic culture, and educational initiatives geared toward building enterprising or entrepreneurial competence. Chapter one provides an introduction to the problem, the questions, the terms and the methodology. Chapter two sets the preoccupation with entrepreneurship now shared by most western societies in contemporary historical perspective. Economic theories of entrepreneurship that have long stressed the importance of instrumental knowledge are briefly introduced, with emphasis on the ideas of Joseph Schumpeter, who remains the authority on entrepreneurship. Schumpeter stressed that values are the starting point for any new economic system, a principle that forms the basis for the remainder of the thesis. The chapter concludes with a discussion of the university community's different perceptions of entrepreneurship as an organizing principle for the creation and diffusion of knowledge, and a contrast of select "enterprise cultures" in western societies. In chapter three, competencies that the literature suggests are part of the entrepreneurial function are delineated. Chapter four discusses educational theories and practices intended to strengthen the enterprising capacities of individuals and societies, focusing upon programs currently implemented and others being proposed. The concluding chapter synthesizes the implications of the study and provides suggestions for further research.

Αναδείξαμε τα σημεία ταύτισης της κοσμοθεωρίας του Καζαντζάκη με αυτή του Νίτσε, αλλά και την ένταση με την οποία βίωσε προσωπικά ο Κρητικός αυτή την επίδραση.
description: The aim of this thesis was to study and present the elements of F. Nietzsche’s philosophy, as they can be found in N. Kazantzaki’s work. Our purpose was to show Nietzsche’s influence on the Cretan writer, the acquisition of the main parts of the German’s philosophy and its assimilation to Kazantzaki’s worldview. We initially pointed out the main corpus of Nietzsche’s philosophical view and how it influenced Greek writers and scholars. In addition, there was an extensive analysis on some of Kazantzaki’s novels, poems or essays which contain significant references to Nietzsche’s philosophy. Furthermore, we examined specific points of N. Kazantzaki’s writings on which he refers directly to Nietzsche, to whom he pays tribute and analyses his philosophy. We presented the common points of Nietzsche’s and Kazantzaki’s worldview and the intensive effect on Cretan’s life.

description: Density-functional calculations on the polar TiX(111) (X = C, N) surfaces show (i) for clean surfaces, strong Ti3d-derived surface resonances (SR's) at the Fermi level and X2p-derived SR's deep in the upper valence band and (ii) for adatoms in periods 1-3, pyramidic trends in atomic adsorption energies, peaking at oxygen (9 eV). A concerted-coupling model, where adatom states couple to both kinds of SR's in a concerted way, describes the adsorption. The chemisorption versatility and the general nature of the model indicate ramifications and predictive abilities in, e.g., growth and catalysis.

description: The nature of the Fermi surface observed in the recently discovered family of unconventional insulators starting with SmB$_6$ and subsequently YbB$_{12}$ is a subject of intense inquiry. Here we shed light on this question by comparing quantum oscillations between the high magnetic field-induced metallic regime in YbB$_{12}$ and the unconventional insulating regime. In the field-induced metallic regime beyond 47 T, we find prominent quantum oscillations in the contactless resistivity characterised by multiple frequencies up to at least 3000 T and heavy effective masses up to at least 17 $m_\text{e}$, characteristic of an $f$-electron hybridised metallic Fermi surface. The growth of quantum oscillation amplitude at low temperatures in electrical transport and magnetic torque in insulating YbB$_{12}$ is closely similar to the Lifshitz-Kosevich low temperature growth of quantum oscillation amplitude in field-induced metallic YbB$_{12}$, pointing to an origin of quantum oscillations in insulating YbB$_{12}$ from in-gap neutral low energy excitations. The field-induced metallic regime of YbB$_{12}$ is characterised by more Fermi surface sheets of heavy quasiparticle effective mass that emerge in addition to the heavy Fermi surface sheets yielding multiple quantum oscillation frequencies below 1000 T observed in both insulating and metallic regimes. We thus observe a heavy multi-component Fermi surface in which $f$-electron hybridisation persists from the unconventional insulating to the field-induced metallic regime of YbB$_{12}$, which is in distinct contrast to the unhybridised conduction electron Fermi surface observed in the case of the unconventional insulator SmB$_6$. Our findings require a different theoretical model of neutral in-gap low energy excitations in which the $f$-electron hybridisation is retained in the case of the unconventional insulator YbB$_{12}$.

description: Sustainable utilization of wildlife resources is assured through implementing efficient and regulated consumption strategy. Therefore, to ensure the sustainability of the wildlife resources of the controlled hunting areas, timely follow ups, monitoring and evaluation to take proper measures is very essential. Accordingly, the objective of this study is to assess wild animals’ population, habitat condition, and set hunting quota in Munessa Kukke Controlled hunting area. Line transects are used to conduct the wildlife census as per the habitat nature of the area. Six lines transect ranging from 2.5km to 5.5km were randomly selected covering 22km length in total. In this case perpendicular sighting distance of 150 meters on both sides of the line transects covering 300 meters in total was used to count forest and thicket animals. All larger mammals encountered along the transects were counted and recorded on the census sheet. Counts were made every morning at dawn from 6:00 AM to 10:00 AM hours.Regarding the distribution of the wild animals Mountain Nyala, and Colobus Black and White are relatively evenly distributed throughout the sampled area; whereas Annubis Baboon and Menelik’s Bushbuck are recorded in four out of the six line transects.On the subject of the age and sex structure of the recorded wild animals the male to female ratio is more or less fairly represented except in the case of Menelik’s Bushbuck where the number of males is about double of the females and no age structure difference is observed and only adults were recorded. Therefore, to investigate the problems and to find out a solution, the team suggests further study to conduct research by concerned bodiesPopulation estimate of the recorded wild animals shows that Mountain Nyala is a relatively at a good population number with an estimate of 985, followed by Annubis Baboon, Colobus Black and White, and Menelik’s Bushbuck having 684 ,423 , and 258 respectively.The unfavorable human activities like poaching and expansion for agriculture would have a greater impact on the abundance and distribution of wild animals in the controlled hunting area. It is therefore advisable to all the stake holders to take immediate actions to counter the problems and make sure the wellbeing of the wild animals in the area. Additionally, wildlife conservation awareness program should be further strengthened by concerned stake holders to get the overall support of the community.

description: The self-energies and the spectral densities of longitudinal and transverse gluons at zero temperature in the color-flavor-locked (CFL) phase are calculated. There appears a collective excitation, a light plasmon, at energies smaller than two times the gap parameter and momenta smaller than about eight times the gap. The minimum in the dispersion relation of this mode at some nonzero value of momentum corresponds to the van Hove singularity.

title: Investigation of Material Removal Mechanism of SiC in Nano-scale Machining Using Molecular Dynamics Simulation
Creators: name: Tian, Z
Publisher: name: Liverpool John Moores University

description: Single crystal silicon carbide is widely used for microelectronics, optoelectronics and medicine sectors because of its specific properties. It is critical to completely eliminate the damaged layer and further reduce the surface roughness of the substrates to meet the requirements of epitaxy processes. Both mechanical removal and chemical removal play significant roles in the ultra-precision polishing. This research aims to investigate the nanomechanical performance, chemical reaction and removal mechanism of 4H-SiC and 6H-SiC polishing using molecular dynamics simulations and experimental validation. Material deformation in the forms of amorphous transformation and dislocations are found to be the primary mechanisms of material removal, which are evidenced in both MD simulation and experiments. The dislocations in the scratched 4H-SiC and 6H-SiC are prone to crack growth when the fractured bonds do not recover. During scratching, dislocations and slips could occur on both the C face and the Si face, mainly on the (0001) basal plane and the (10-10) plane. It is found that the stress peak of scratching on C face is lower, which means the dislocations at C face on the (0001) plane occur more easily. Material removal efficiency of the C face is higher than that of the Si face, and there is less subsurface amorphous deformation on the C face. Moreover, in both experimental and simulation results, machining conditions, such as shape of abrasive particles, scratching speed and scratching direction, also have significant effects on nanometric material removal performance. Setting the scratching cutting depth as an integer multiple of the height of a half lattice crystal may be more beneficial for removing materials and better subsurface quality of substrates. The occurrence of silicon dioxide when pure water is applied as the cooling liquid indicates that the 6H-SiC wafers can be oxidized by the water during polishing without any acid or alkali conditions. The occurrence and extent of the reactions between SiC and H2O are influenced by the destruction of the 6H-SiC lattice structures. The material on the C face of 6H-SiC is oxidized faster than that on the Si face, directly resulting in a larger removal efficiency of the C face than the Si face in the same conditions. The research methods introduced in this research could also be applicable for the investigation of different SiC polytypes and other brittle materials. Understanding these problems could be beneficial to nanomachining of these hard and brittle materials.

Classical dynamics on triangleland

description: In Euclidean relational particle mechanics (ERPM) only relative times, relative angles and relative separations are meaningful, while in similarity relational particle mechanics (SRPM) only relative times, relative angles and ratios of relative separations are. These theories are clearly of interest in the absolute or relative motion debate. In this paper, ERPM and SRPM are provided in fully reduced form for 3 particles in 2D, i.e. the classical dynamics on triangleland in 2D with and without scale. Exact solutions to each of these are then found, and simple Newton--Coulomb-like and harmonic oscillator-like SRPM models are studied numerically. The mathematics one arrives at thus overlaps in many ways with that which arises in the absolutist approach. The ERPM gives standard mathematics, while the SRPM has standard small-relative-scale behaviour and an unexpected but in itself standard universal large-relative-scale behaviour. One way in which SRPM is unusual is that it is a model in which a symmetry principle underlies an unexpected departure from standard physical behaviour at sufficiently large relative scales (interpolation between the abovementioned two behaviours). ERPM and SRPM are also theoretically interesting at the quantum level, both on their own merit and as toy models for the development of various approaches to the problems of time and of observables in quantum general relativity.
