Raman spectroscopy of Fe2O3 to 62 GPa

Abstract Raman spectra of Fe2O3 were measured to 62 GPa in a diamond anvil cell. All group theoretically predicted Raman-active phonon modes were detected to 54 GPa. In addition, some high-pressure spectra show an IR-active Eu mode (~660 cm-1), possibly induced by surface defects or stress. This mode is related by a factor of two to a mode at 1320 cm-1. The assignment of the 1320 cm-1 mode has been controversial (two-magnon scattering or two-phonon scattering), and our observation supports the phonon assignment. All Raman-active phonons show nonlinear pressure-induced shifts. The mode Grüneisen parameters and their logarithmic volume dependences for two low-frequency phonons, A1g and Eg, become negative and infinite, respectively, near 50 GPa as a result of the instability of the corundum structure at this pressure. Using the observed Raman-active phonons together with acoustic phonons previously measured by ultrasonics, and Kieffer’s model, we calculate the phonon contribution to the thermodynamic parameters of hematite. Comparison with experimentally measured values allows an estimation of an upper bound to the magnon contribution to the heat capacity at ambient pressure. This increases continuously above the Morin temperature and reaches a maximum at the Néel temperature (~37%). The Raman spectra change dramatically at pressures greater than 54 GPa as indicated by the appearance of new peaks and a significant increase in background. Although direct structural analysis is not possible due to the low signal-to-background ratio and the lack of polarization information, we were able to examine the consistency of our Raman observation with the corundum-to-perovskite phase transformation using the results for an analog system: MgSiO3 ilmenite (ordered corundum type) and perovskite. This analysis shows that observed new features in Fe2O3 Raman spectra may not be consistent with the GdFeO3 perovskite structure.
Diabetic Retinopathy: Battling the Global Epidemic

Blindness is increasing rapidly worldwide due to diabetes mellitus, a devastating disease that has assumed the proportions of a global epidemic. Over 415 million people in the world have diabetes, and it is estimated that this number will reach around 642 million by 2040.1 Early detection and prompt treatment are still the gold standards of managing diabetic retinopathy (DR), and landmark clinical trials have shown that such treatment can effectively decrease visual disability by 90%. Despite tremendous progress in the developments of treatment for this disease, many questions remain unanswered.

THE EFFECT OF APPLYING OREM SELF-CARE MODEL ON SELF CARE ABILITY IN PATIENTS HOSPITALIZED IN THE INTERNAL CARDIAC MEDICINE UNIT IN EMAM REZA HOSPITAL, SIRJAN

The most important causes for mortality rate and re admission in patients with heart disease arise from insufficient education and inappropriate self care. This study determines the effect of applying Orem self-care model on self care ability in patients hospitalized in the internal cardiac unit in Emam Reza hospital of Sirjan. Materials and Methods: In this clinical trial study, 80 patients with known heart disease were selected randomly, and they were divided in to two groups of experimental and control. A pre test was performed. The patients, in the experiment group, received 5 education sessions by implementing Orem's model, each lasting twenty minutes during the hospital stay, and also they were given an educational pamphlet. The control patients received routine care the patients in both groups. Post test was performed. The data were analyzed via SPSS soft ware version 16. Result: The mean score for self care cognitive abilities in the experimental group before the intervention increased from 2/03 ± 0/15 to12 ±0/001 after the intervention. The mean score of self care performance ability in the experimental group, increased from 32/28 ± 9/51 to 105/43 ± 3/96 after the intervention. Significant differences between self care ability before and after the intervention were observed (p 0/05). Conclusion: Applying of Orem's self care model had a positive influence on raising the self care ability of the patients with heart disease. Therefore, the application of Orem's model is suggested in the care of patients with chronic, especially heart patients
STUDY OF BODY DIMENSION OF GAGA CHICKEN, GERM PLASM OF LOCAL CHICKENFROM SOUTH SULAWESI-INDONESIA

Gaga’ chicken is the local chicken at South Sulawesi that have unique, specific, and different crowing sound with the other types of crowing chicken in the world. This uniqueness of Gaga’ chicken was especially at the ending of crowing sound which is like the voice character of human laughing. Unfortunately, the scientific information of the phenotypic description and morphological traits of Gaga’ chicken was limited. This study was carried out to determine some body dimensions of Gaga’ chicken and to demonstrate the correlations between these body measurements and live weight for providing more accurate data that can be used in breeding and development of Gaga’ chicken as one of the ornamental chicken in Indonesia. The body measurement parameters, which were recorded from 57 birds Gaga’ chicken, were body weight, shank length, shank circumference, drumstick length, thight lenght, keel length, chest girth, breast width, body length, wing length, beak width, and comb height. The measurement were using weight scale, metric line, and caliper. Some body dimensions of Gaga’ chicken were similar to Kampong chicken except shank circumference, drumstick length, wing length, and comb height of Gaga’ chicken tended to be larger. The correlation coefficient range between body dimensions of Gaga’ chicken were low to high (0.171 to 0.710). Highest correlation was shown between body weight and chest girth and that result can be choosed as one of the selection criteria of Gaga’ chicken.

PERFORMANCE EVALUATION OF NEURAL NETWORK BASED HAND GESTURE RECOGINITION

With the development of information technology in our Society one can expect that computer systems to a larger extent will be embedded into our daily life. These environments lead to the new types of human-computer interaction (HCI). The use of hand gestures provides an attractive alternative to cumbersome interface devices for human-computer interaction (HCI). The existing HCI techniques may become a bottleneck in the effective utilization of the available information flow. Gestures are expressive, meaningful body motions. Interpretation of human gestures such as hand movements or facial expressions, using mathematical algorithms is done using gesture recognition. Gesture recognition is also important for developing alternative human-computer interaction modalities. This research will have tested the proposed algorithm over 100 sign images of ASL. The simulation will show that the true match rate is increased from 77.7% to 84% while the false match rate is decreased from 8.33 % to 7.4%.
Strong dust processing in circumstellar discs around 6 RV Tauri stars. Are dusty RV Tauri stars all binaries

We present extended Spectral Energy Distributions (SEDs) of seven classical RV Tauri stars, using newly obtained submillimetre continuum measurements and Geneva optical photometry supplemented with literature data. The broad-band SEDs show a large IR excess with a black-body slope at long wavelengths in six of the seven stars, R Set being the noticeable exception. This long wavelength slope is best explained assuming the presence of a dust component of large grains in the circumstellar material. We show that the most likely distribution of the circumstellar dust around the six systems is that the dust resides in a disc. Moreover, very small outflow velocities are needed to explain the presence of dust near the sublimation temperature and we speculate that the discs are Keplerian. The structure and evolution of these compact discs are as yet not understood but a likely prerequisite for their formation is that the dusty RV Tauri stars are binaries.
Parametrically Temperature-Dependent Potential for Molecular Dynamics Simulation of Uranium Dioxide Properties

The present paper justifies the application of the temperature-dependent potential to the molecular dynamics method through the example of uranium dioxide. Substantiation of the temperature dependence of interatomic potential is carried out based on the Newton quantum equation. Mean force can be represented as a sum of derivative of potential at the average atomic coordinate and the summand that depends on square dispersion of the coordinate depending on the temperature of the crystal. Temperature dependence of potential is introduced as linear slightly varying functions of the Coulomb plus Buckingham potential. The selection of parameters of potential was done at three temperature values: the initial temperature and temperatures of phase transitions – 2670 and 3120K, parameters of potentials for all other temperatures were found by approximation. We calculated temperature dependencies for the lattice constant, enthalpy, heat capacity under constant pressure and volume. Application of the temperature-dependent potential well complies with experimental data; the difference did not exceed 0.5% in the entire temperature range of 300-3120K.
Equity Market Integration of New EU Member States

This study assesses the degree of equity market integration for a selected number of new EU member states among themselves and with the euro zone. Within the framework of a factor model for market returns, we adopt an intuitive measure of integration: the higher the amount of return variance explained by the global factor relative to the local components, the higher the degree of integration. Next we derive a relationship between return correlation and the measure of integration. Equity market integration is measured with a regression quantilebased methodology. Evidence suggests that for Czech Republic, Hungary and Poland the degree of integration has increased significantly over the last few years. This is not the case for Cyprus, Estonia, Latvia and Slovenia.
Fabrication and near-infrared optical responses of 2D periodical Au/ITO nanocomposite arrays

Two-dimensional (2D) periodical Au and indium tin oxide (ITO) nanocomposite arrays have been fabricated based on a self-assembled nanosphere lithography technique. A button-shaped Au nanoparticle was formed on each hollow hemisphere-shaped ITO shell. Importantly, the underlying formation mechanism during the thermal treatment has been thoroughly explored by comparing structures resulting from different deposition conditions in detail. Compared to the Au nanoparticle arrays without ITO shells, the Au/ITO nanocomposite arrays showed a stronger localized surface plasmon resonance effect and higher absorption in the near-infrared (NIR) region, benefiting from the free-electron interaction enhancement between Au and ITO. The nonlinear optical properties were investigated using a modified femtosecond intensity-scan system, and the results demonstrated Au/ITO nanocomposite arrays with a remarkable two-photon absorption saturation effect for femtosecond pulses at 1030 nm. The versatile NIR optical responses indicate the great potential of the elaborately prepared 2D periodical Au/ITO nanocomposite arrays in many applications such as solar cells, photocatalysis, and novel nano optoelectronic devices.
Evaluation of two precipitation data sets for the Rhine River using streamflow simulations

Abstract. This paper presents an extended version of a widely used precipitation data set and evaluates it along with a recently released precipitation data set, using streamflow simulations. First, the existing precipitation data set issued by the Commission for the Hydrology of the Rhine basin (CHR), originally covering the period 1961–1995, was extended until 2008 using a number of additional precipitation data sets. Next, the extended version of the CHR, together with E-OBS Version 4 (ECA & D gridded data set) were evaluated for their performance in the Rhine basin for extreme events. Finally, the two aforementioned precipitation data sets and a meteorological reanalysis data set were used to force a hydrological model, evaluating the influence of different precipitation forcings on the annual mean and extreme discharges compared to observational discharges for the period from 1990 until 2008. The extended version of CHR showed good agreement in terms of mean annual cycle, extreme discharge (both high and low flows), and spatial distribution of correlations with observed discharge. E-OBS performed well with respect to extreme discharge. However, its performance of the mean annual cycle in winter was rather poor and remarkably well in the summer. Also, CHR08 outperformed E-OBS in terms of temporal correlations in most of the analyzed sub-catchment means. The length extension for the CHR and the even longer length of E-OBS permit the assessment of extreme discharge and precipitation values with lower uncertainty for longer return periods. This assessment classifies both of the presented precipitation data sets as possible reference data sets for future studies in hydrological applications.
Crime and public transport : designing a safer journey

One of the major concerns of the majority of South Africans is the relatively high levels of crime. The transport sector faces its own set of challenges in this regard. For instance, the fact that the majority of poorer people stay relatively far away from their places of employment requires them to spend a considerable amount of time travelling. Commuters are very vulnerable to crime during these journeys. They are exposed to being victimised on busses, trains or minibus taxis, while changing from one mode of transport to another at stations, or when walking from drop-off points to their places of work or to their homes. This paper addresses issues related to transport and security with a particular focus on the role that the physical environment plays in increasing or reducing opportunities for crime. The focus is on crime problems on public transport and the use of specific planning and design interventions to reduce crime in the South African context.
Compact Microstrip Low-pass Filter with Wide Stop-band Using P-Shaped Resonator

This paper, a compact lowpass filter (LPF) with an Elliptic function response using P-shaped resonators is presented. The LPF with simple structure results in the low insertion loss less than 0.1 dB and high return loss better than 20 dB, in the passband. The proposed filter with a -3 dB cutoff frequency of 2.61 GHz is fabricated and measured. The measured results show that the proposed LPF has significant advantages such as a wide stopband from 2.9 GHz to 17.3 GHz with the suppression level better than -20 dB, and it has an acceptable sharp frequency response in the transition band. The measurement results are in good agreement with the simulation results.
The generalized optical memory effect

The optical memory effect is a well-known type of wave correlation that is observed in coherent fields that scatter through thin and diffusive materials, like biological tissue. It is a fundamental physical property of scattering media that can be harnessed for deep-tissue microscopy or 'through-the-wall' imaging applications. Here we show that the optical memory effect is a special case of a far more general class of wave correlation. Our new theoretical framework explains how waves remain correlated over both space and angle when they are jointly shifted and tilted inside scattering media of arbitrary geometry. We experimentally demonstrate the existence of such coupled correlations and describe how they can be used to optimize the scanning range in adaptive optics microscopes.
PREGNANCY RATES AFTER COMPULSATORY ONE AND CONDITIONAL TWO EMBRIYO TRANSFER POLICY

SUMMARY 2011. Results: Our clinical pregnancy rate was 31% and implantation rate was 25%. Our pregnancy rates after one or two ET were 30 and 32 % respectively ( P>0.05). We transferred embryos at second, third day or blastocyst stage. Pregnancy rates were 19, 30 and 48 % respectively (p< 0.001), implantation rates were 14.5, 23.5 and 42.4 % respectively ( P< 0.001). Our freezing rate was 39.5 %. From not to have freezing quality embryos to have, increased the pregnancy rate from 21% to %45 significantly. When one ET ed 95 % single and 5 % twins observed. When two embryos were transferred 81% single,17% twin and 2 % triplets observed. Conclusion: Pregnancy rates for one or two ET were statistically similar. If embryo quality allows us to culture up to blastocyt stage pregnancy rates were statistically increased.New Turkish ET policy resulted 95 % to 81 % single gestational sacs according to 1 or 2 ET at Gazi University IVF center.
Exploring the Reasons Why University Students Prefer Print over Digital Texts: An Australian Perspective

ABSTRACT This paper presents findings from an Australian survey that provides an analysis of the reasons why university students prefer to read print or digital course materials. This survey was undertaken as part of the Academic Reading Format International Study (ARFIS), which is investigating print versus digital reading preferences in 31 countries (Mizrachi et al., 2018). A total of 582 students completed the survey with 471 students providing comments. This article provides an in-depth analysis of the comments from the survey. The comments provided in this survey provide rich data on the reasons why students prefer reading in print or electronic formats, an area of importance due to the increasing prevalence of digital only collections in university libraries. Based on comments, students preferred print due to reasons such as accessibility, eyestrain, tactile features, better focus and ability to highlight and take notes. Although students prefer print, they acknowledge the convenience and cheaper costs of e-texts. Students who were e-preferring were influenced by issues such as cost, environment and convenience. In light of library collections prioritising digital content, tertiary institutions and libraries should carefully consider the role that print textbooks and collections, as well as printing services, may play in supporting student learning.
A lambda=3 mm molecular line survey of NGC1068. Chemical signatures of an AGN environment

We aimed to study the molecular composition of the interstellar medium (ISM) surrounding an Active Galactic Nucleus (AGN), by making an inventory of molecular species and their abundances, as well as to establish a chemical differentiation between starburst galaxies and AGN. We used the IRAM-30 m telescope to observe the central 1.5-2 kpc region of NGC1068, covering the frequencies between 86.2 GHz and 115.6 GHz. Using Boltzmann diagrams, we calculated the column densities of the detected molecules. We used a chemical model to reproduce the abundances found in the AGN, to determine the origin of each detected species, and to test the influence of UV fields, cosmic rays, and shocks on the ISM. We identified 24 different molecular species and isotopologues, among which HC3N, SO, N2H+, CH3CN, NS, 13CN, and HN13C are detected for the first time in NGC1068. We obtained the upper limits to the isotopic ratios 12C/13C=49, 16O/18O=177 and 32S/34S=5. Our chemical models suggest that the chemistry in the nucleus of NGC1068 is strongly influenced by cosmic rays, although high values of both cosmic rays and far ultraviolet (FUV) radiation fields also explain well the observations. The gas in the nucleus of NGC1068 has a different chemical composition as compared to starburst galaxies. The distinct physical processes dominating galaxy nuclei (e.g. C-shocks, UV fields, X-rays, cosmic rays) leave clear imprints in the chemistry of the gas, which allow to characterise the nucleus activity by its molecular abundances.

Discretionary Bonuses as a Feedback Mechanism

This paper studies the use of discretionary rewards in a finitely repeated principal-agent relationship with moral hazard. We show that the principal, when she obtains a private subjective signal about the agent’s performance, may pay discretionary bonuses to provide credible feedback to the agent. Conistent with the often observed compression of ratings, we show that in equilibrium the principal communicates the agent’s interim performance imperfectly, i.e. she does not fully di? erentiate good and bad performance. Furthermore, we show that small rewards can have a large impact on the agent’s effort provided that the principal’s stake in the project is small. Our analysis further reveals that, also in accordance with the empirical findings, the principal may ex ante prefer to choose a ’smoky’, rather than a fully transparent performance monitoring system, thereby acquiring an implicit commitment device to reward the agent through discretionary bonuses.
