description: Abstract Background: The study focuses on the evidence of the relationship between water quality and the health of populations. Colombia, a country with high levels of economic, social, and environmental vulnerability, does not have a population that has full access to drinking water. The study analyzes this relationship in Guamachito, Zona Bananera, Colombia. Objective: Analyze the water quality and the effect on the health of the population of Guamachito, Zona Bananera, Colombia. Method: Cross-sectional quantitative study, which was carried out in phases: First, an analysis of secondary data was carried out through a review of the web pages of the government institutions of public health in the region and the country; subsequently, a survey was applied to contrast the results of the documentary review to 450 inhabitants of Guamachito, Colombia, corresponding to members of a rural educational institution in the municipality, with 24 teachers and 426 students. Results: The results suggest that the microbiological characteristics are above the reference limits, as well as poor procedures for collecting and cleaning water in the houses, likewise, high rates of water-borne diseases are identified. Conclusion: It is inferred that there is an incidence of water quality on the health of the inhabitants of the Guamachito municipality. [Ethiop. J.

description: We present a multi-mission X-ray analysis of a bright (peak observed 0.3-10 keV luminosity of ~ 6x10^{40} erg s^{-1}), but relatively highly absorbed ULX in the edge-on spiral galaxy NGC 5907. The ULX is spectrally hard in X-rays (Gamma ~ 1.2-1.7, when fitted with an absorbed power-law), and has a previously-reported hard spectral break consistent with it being in the ultraluminous accretion state. It is also relatively highly absorbed for a ULX, with a column of ~ 0.4-0.9x10^{22} atom cm^{-2} in addition to the line-of-sight column in our Galaxy. Although its X-ray spectra are well represented by accretion disc models, its variability characteristics argue against this interpretation. The ULX spectra instead appear dominated by a cool, optically-thick Comptonising corona. We discuss how the measured 9 per cent rms variability and a hardening of the spectrum as its flux diminishes might be reconciled with the effects of a very massive, radiatively-driven wind, and subtle changes in the corona respectively. We speculate that the cool disc-like spectral component thought to be produced by the wind in other ULXs may be missing from the observed spectrum due to a combination of a low temperature (~ 0.1 keV), and the high column to the ULX. We find no evidence, other than its extreme X-ray luminosity, for the presence of an intermediate mass black hole (~ 10^2 - 10^4 Msun) in this object. Rather, the observations can be consistently explained by a massive (greater than ~ 20 Msun) stellar remnant black hole in a super-Eddington accretion state.

description: Abstract Background: Coronavirus pandemic has drastically change health institutions due to modifications to the health service delivery system. In line with this, patients visiting health institutions have markedly reduced numbers resulting in a reduced caseload of practicing physicians. Objective: This paper assessed the caseload in the radiology department of Tikur Anbessa Specialized Hospital and reported turnaround times before and after the COVID-19 pandemic in a tertiary teaching hospital. Methods: Institution-based Cross-sectional study design was employed for the radiology caseload. All patients’ groups seen in radiology department in all the modalities 6 months before and after the announcement of the COVID-19 in Ethiopia. For the evaluation of radiology report turnaround time, simple random sampling was employed using the source population as those 6 months before in 6 months after the declaration of Covid in Ethiopia. Data entry and analysis were done using SPSS version 16 statistical software. Time series analysis with 95% CI was used to determine the association between different variables for radiology caseloads. Result: The trend of patient load showed a marked decrease after the COVID-19 pandemic in the radiology department. The turnaround time from study time to residents’ report time (ST-RT) - after COVID-19 for MRI was increased by 17 hours. But resident report time to consultant verification time (RRT-CVT) was decreased by 1 day after the COVID-19 pandemic. For computed tomography [CT], ST-RT has decreased by 1 day and 4 hours but RRT-CVT time showed a slight increment by 1 hour and 30 min as compared to before COVID-19. This resulted in reduced exposure of residents and delays of verified patient reports. Conclusion: there is a decrease in patient load and an increase in turnaround time of radiology case reports after the COVID-19 pandemic compared with the trend before the pandemic. This will affect patient care and resident teaching. The department should look for ways of improving patient care and resident teaching through different innovative methods like the introduction of virtual education and teleradiology. [Ethiop. J.

description: The Replica Exchange Wang-Landau Method is used to estimate the energy landscape of a polymer composed of a simple hydrophobic and polar sequence using the HP protein model. Calculations of state transitions between the energy levels of the derived energy landscape are made using an equation of motion from the steepest-entropy-ascent quantum thermodynamic (SEAQT) framework. The SEAQT framework makes it possible to determine the unique kinetic paths from an arbitrary quasi-equilibrium or non-equilibrium initial state to stable equilibrium. Calculations performed with SEAQT require significantly reduced computational time versus comparable Monte Carlo simulations while providing otherwise unavailable thermodynamic and structural properties. Expected values for state averaged structural parameters are used to produce representative reconstructions of the calculated state-based evolution. Results show continuous transitions between states with no distinct folding phases. Changes in chain conformations during heating and cooling are more drastic along non-equilibrium paths than along quasi-equilibrium paths. In addition, SEAQT-derived kinetics are compared to experimentally derived intensity profiles describing the kinetics of the cytochrome c protein using Rouse dynamic relations.

description: We use a multiscale approach to study a lattice-gas model of submonolayer growth of Fe/Mo(110) by Molecular Beam Epitaxy. To begin with, we construct a two-dimensional lattice-gas model of the Fe/Mo(110) system based on first-principles calculations of the monomer diffusion barrier and adatom-adatom interactions. The model is investigated by equilibrium Monte Carlo (MC) simulations to compute the diffusion coefficients of Fe islands of different sizes. These quantities are then used as input to the coarse-grained Kinetic Rate Equation (KRE) approach, which provides time evolution of the island size distributions for a system undergoing diffusion driven aggregation within the 2D submonolayer regime. We calculate these distributions at temperatures T=500 K and 1000 K using the KRE method. We also employ direct kinetic MC simulations of our model to study island growth at T=500 K, and find good agreement with the KRE results, which validates our multi-scale approach.

description: Pseudo-magnetic field becomes an experimental reality after the observation of zero-field Landau level-like quantization in strained graphene, but it is not expected that the time-reversal symmetric pseudo-magnetic fields will have any effect on the spin degree of freedom of the charge carriers. Here, we demonstrate that spin-orbit coupling (SOC) could act as a bridge between pseudo-magnetic field and spin. In quantum spin Hall (QSH) states, the direction of the spin of edge states is tied to their direction of motion because of the SOC. The pseudo-magnetic field affects the clockwise and counter-clock-wise edge currents of the QSH states, and consequently lifts the degenerate edge states of opposite spin orientation. Because of opposite signs of the pseudo-magnetic field in two valleys of graphene, the one-dimensional charge carriers at the two opposite edges have different group velocities, and in some special cases the edge states can only propagate at one edge of the nanoribbon and the group velocity at the other edge becomes zero.

We briefly describe a method for constructing surfaces with a given symmetry. We discuss all minimal embeddings of the Schwarzschild metric obtained using this method and show how the method can be used to construct all minimal embeddings for the Friedmann models. We classify all the embeddings in terms of realizations of symmetries of the corresponding solutions.

title: Catastrophic disruption of layered ice-silicate bodies
Creators: name: Lightwing, Andrew
Publisher: name: University of Kent
Year: 2023

description: Large icy Kuiper Belt Objects (KBOs) such as Pluto have observed densities on the order of 1.8 - 2.0 g cm⁻³. This indicates that they are made up of some combination of ice and silicate material; their size further implies that they will possess a differentiated structure with ice dominating towards the surface and silicate material dominating towards the core. A series of impact experiments using the University of Kent’s light gas gun have been carried out in order to determine the impact strength of spherical layered ice-silicate targets that reflect the suspected structure of these bodies. Impacts are also carried out on unlayered ice-silicate targets and pure ice targets for the purposes of comparison. Impact velocities ranged from 1 to 7 km s⁻¹ using a range of projectile sizes and materials including stainless steel, titanium, aluminium and copper. Data from previous work undertaken at the University of Kent is incorporated in order to provide a more complete picture of target behaviour. Basic spherical ice-silicate targets with diameters of 40mm yield critical energy densities (Q*) of 270 (+2/-26) J kg⁻¹ for 0.8mm stainless steel projectile impacts and 309 (+55/4) J kg⁻¹ for 1mm titanium projectile impacts. This makes them much stronger than large spherical pure ice targets (diameter 0.4 - 1 m) and pure ice cylinders which have critical energy densities of 5.7 (+1.6/-1.2) J kg⁻¹ and 8.1 (+4/- 2.7) J kg⁻¹ respectively when impacted with 1mm copper projectiles. 40mm diameter spherical pure ice targets have a higher energy density of 45 ± 3 J kg'1 when impacted with 1mm aluminium projectiles, indicating some Q* dependence on target size and projectile size which is borne out by other data sets. Size distribution and energy density plots indicate that targets also exhibit different behaviour when impacted at very high energy densities compared to the behaviour displayed at energy densities around the critical energy density. The addition of an ice layer has little to no effect up to a thickness of five times the projectile diameter, after which target strength is increased dramatically to a Q* of 912 (+20/-18) J kg⁻¹ for impacts by 1mm titanium projectiles. However this may not be an accurate reflection of the true strength of large KBOs due to the still-basic nature of the layered targets.

description: A multiple scale model approach is presented in order to investigate Al2O3 thin film growth in the framework of an existing Ion Beam Sputtering (IBS) coating process. Therefore, several simulation techniques are combined via optimized interfaces for realizing the concept of a virtual coater. Characteristic coating process parameters of the IBS coating plant are applied as input parameters to model the material transport in the chamber, the energy and angular distribution of the coating material at the substrate, the formation of structural thin film properties, and the optical as well as the electronic layer properties. The resulting thin film properties are validated to the data of an experimental IBS Al2O3 single layer prepared applying the underlying coating facility. The comparison accounts for a good agreement between the modeled layer properties using the virtual coater concept and the experimental characterization data. © 2015 SPIE.

description: We have studied quantized transport in HgTe wells with inverted band structure corresponding to the two-dimensional topological insulator phase (2D TI) with locally-controlled density allowing n-p-n and n-2D TI-n junctions. The resistance reveals the fractional plateau $2h/e^{2}$ in n-p-n regime in the presence of the strong perpendicular magnetic field. We found that in n-2D TI-n regime the plateaux in resistance in not universal and results from the edge state equilibration at the interface between chiral and helical edge modes. We provided the simple model describing the resistance quantization in n-2D TI-n regime.

description: Augmentations to the Euler-Heisenberg Lagrangian (QED one-loop effective action in homogeneous electromagnetic fields) under a constant background axial gauge are examined. Two special configurations admit an exact eigendecomposition, and hence effective action as a spectral sum, of the augmented Dirac operator: one with a magnetic field with chiral chemical potential, and the other with an electric field with spatial axial gauge, which resembles an emergent vorticity. An enhancement to Schwinger pair production is found for the latter, which is more fully analyzed using the worldline instanton formalism. There it is found the overall enhancement is due to the spatial axial gauge serving as a negative mass shift. Finally, we remark on the exactly solvable massless case for arbitrary electromagnetic and axial gauges.

description: We present a fringe projection system to measure glowing hot hybrid components in between production processes. For this a high power green light projector, based on TI DLP technology, is used to create the highest possible contrast between fringes on the red glowing specimen. It has a resolution of 1140 x 912 pixels with a maximum frame rate of 120 images per second for fast measurement. We use a green bandpass filter (525 nm) on the camera lens to block unwanted incoming radiation from the specimen caused by self-emission. Commercial measurement standards are not calibrated for temperatures other than 20° C, so they cannot be used to validate measurement data at the required temperatures of up to 1000°C since thermal expansion invalidates the geometry specification from the calibration data sheet. In our first development we use a uniformly heated pipe made of stainless steel as a dummy specimen to examine the measured geometry data. A pyrometer measures the temperature of the pipe so the expansion can be easily calculated using the thermal expansion coefficient. Different impact and triangulation angles are investigated to identify the effects of hot ambient air on the measurement. The impact of the induced refractive index gradient is examined to check the need for pre-processing steps in the measurement routine. © 2017 SPIE.

description: Abstract Background: Bread is one of the most consumed foods by humankind throughout history. It is important to evaluate the factors affecting the food preferences of individuals and to examine the effect of frequently consumed food on anthropometric measurements and daily energy and macronutrient intake in order to improve public health and develop nutrition policies of society. Objective: The aim of the current study was two-fold: (1) to determine the factors affecting the bread type preferences of individuals (2) to compare anthropometric measurements and macronutrient differences according to bread type preferences. Methods: The study was conducted cross-sectional from January to October 2018 with randomly selected 1554 volunteer individuals aged between 18-65 years in Istanbul Province of Turkey. The data of the study were collected through a questionnaire form applied by the face-to-face interview method. Demographic information, anthropometric measurements, the most consumed bread types, and dietary records were examined in the questionnaire form. Results: It was determined that the preference for white bread was high (%66.3). White bread and whole-grain bread were consumed 159.4±94 g/day and 131.2±89.2 g/day, respectively. BMI and waist circumference were lower, while the difference was not significant. It was determined that the group who preferred whole-grain bread had fewer carbohydrates, higher fiber, higher protein, higher fat, higher saturated fat, and higher cholesterol intakes in their daily diets. Women, having high education status and old-age popularity increased the preference of whole-grain bread 1.73, 3.39, and 1.03 times compared to the preference of white bread (p<0.001). Conclusion: It has been determined that white bread is preferred more in society. Bread type preference was not associated with anthropometric measurements. It has been determined that the distribution of daily macronutrients of individuals who prefer whole-grain bread is more unbalanced. It was found that gender, educational status, and age were the factors affecting the preference of bread type. [Ethiop. J.

description: Phase slips in a one-dimensional closed array of Josephson junctions hybridize the persistent current states (PCS) and plasmon branches of excitations. The interference between phase slips passing through different junctions of the array makes the hybridization sensitive to the charges of the superconducting islands comprising the array. This in turn results in the Aharonov-Casher effect for plasmons, which in absence of phase slips are insensitive to island charges.

description: Architectural Design Rewriting (ADR, for short) is a rule-based formal framework for modelling the evolution of architectures of distributed systems. Rules allow ADR graphs to be refined. After equipping ADR with a simple logic, we equip rules with pre- and post-conditions; the former constraints the applicability of the rules while the later specifies properties of the resulting graphs. We give an algorithm to compute the weakest pre-condition out of a rule and its post-condition. On top of this algorithm, we design a simple methodology that allows us to select which rules can be applied at the architectural level to reconfigure a system so to regain its architectural style when it becomes compromised by unexpected run-time reconfigurations.

description: Il 23 ottobre 2021, l’Istituto Nazionale di Astrofisica (INAF) ha lanciato la seconda edizione del Concorso di scrittura a tema astronomico ispirato a Gianni Rodari, “A Gianni Rodari, via Lattea quaraquarinci”. Il Concorso, a cura del Gruppo Storie dell’INAF e in collaborazione con EduINAF, è rivolto agli studenti della scuola primaria e secondaria di primo grado (6-13 anni). In questa seconda edizione, il Concorso ha aperto le porte alla partecipazione di classe oltre a quella individuale, ricevendo 168 opere individuali e 44 di classe. Come nella prima edizione, l’accoglienza è stata estremamente calorosa, i giovani partecipanti – e in generale il loro contesto scolastico e famigliare – hanno risposto positivamente e con entusiasmo alla sfida. La collaborazione del Concorso con i progetti dell’INAF PRISMA e Sorvegliati Spaziali ha portato alla scelta del tema dell’edizione che quest’anno ha riguardato gli “Asteroidi e altri sorvegliati spaziali”. La seconda edizione ha goduto di un aumento di personale INAF nel gruppo di lavoro del Concorso, permettendo un più efficace divisione dei ruoli e del carico di lavoro: persone di diversi profili e sedi dell’INAF hanno collaborato fra loro e con professionalità esterne quali Emanuela Bussolati (autrice e illustratrice per l’infanzia), Cesare Sottocorno (docente) e Francesca Poppi (illustratrice, graphic e web designer). In questo Report sono discussi i punti salienti della seconda edizione del Concorso, un confronto con la prima edizione e le criticità rilevate.

description: Abstract Objective: To explore the clinical effects of procedural health exercises on the prevention of postoperative deep vein thrombosis in patients following pneumonectomy. In this manuscript patients who had thoracic surgery were included in this study to explore the effects of DVT after exercise. Method: 118 patients admitted to the hospital from January to December 2020 were selected and assigned into two groups according to the time of admission. 51 patients from January to June 2020 were set as the control group, 67 patients from July to December 2020 were selected as part of the observation group. The control group was provided with routine nursing following a lung operation. The observation group was opened 6 hours after the operation except for the routine nursing. The blood flow velocity of the femoral vein and popliteal vein and the occurrence of deep vein thrombosis were compared between the two groups. Results: There were three cases of lower extremity venous thrombosis in the observation group, which was significantly lower than that in the control group (6 cases). The blood flow velocity of the lower extremity deep vein in the observation group was higher than that of the control group (p<0.05). Conclusion: Routine health exercises can effectively improve the blood flow velocity of the lower extremity vein, by reducing the incidence of lower extremity deep vein thrombosis following pneumonectomy, and by improving the quality of life of patients, which is worthy of clinical promotion.

description: Given a supervector bundle $E = E_0\oplus E_1 \to M$, we exhibit a parametrization of Quillen superconnections on $E$ by graded connections on the Cartan-Koszul supermanifold $(M;Ω(M))$. The relation between the curvatures of both kind of connections, and their associated Chern classes, is discussed in detail. In particular, we find that Chern classes for graded vector bundles on split supermanifolds can be computed through the associated Quillen superconnections.

description: The intricacy of 3D surfaces often results cutting-edge point cloud denoising (PCD) models in surface degradation including remnant noise, wrongly-removed geometric details. Although using multi-scale patches to encode the geometry of a point has become the common wisdom in PCD, we find that simple aggregation of extracted multi-scale features can not adaptively utilize the appropriate scale information according to the geometric information around noisy points. It leads to surface degradation, especially for points close to edges and points on complex curved surfaces. We raise an intriguing question -- if employing multi-scale geometric perception information to guide the network to utilize multi-scale information, can eliminate the severe surface degradation problem? To answer it, we propose a Multi-offset Denoising Network (MODNet) customized for multi-scale patches. First, we extract the low-level feature of three scales patches by patch feature encoders. Second, a multi-scale perception module is designed to embed multi-scale geometric information for each scale feature and regress multi-scale weights to guide a multi-offset denoising displacement. Third, a multi-offset decoder regresses three scale offsets, which are guided by the multi-scale weights to predict the final displacement by weighting them adaptively. Experiments demonstrate that our method achieves new state-of-the-art performance on both synthetic and real-scanned datasets.

description: Abstract Background: Maternal mortality remains a public health challenge in most developing countries. Adequate utilisation of maternal health care services could be an effective means of reducing maternal mortality and morbidity. Mass media has the potential to promote maternal healthcare utilisation because it has been used successfully in several health programs. Objective: This study is aimed at exploring associations between exposure to different types of mass media and maternal healthcare utilisation among women in Zimbabwe. Methods: The study used a -cross-sectional study design to conduct a secondary analysis of data collected in the 2015 Zimbabwe Demographic and Health Survey (ZDHS). Women who had given birth in the last 5 years preceding the survey were included in this study. Women with missing information about their maternal healthcare and media exposure were excluded, leaving 4988 women in the final analytical sample. Multivariable logistic regression was used to determine the association between exposure to different types of mass media and maternal healthcare utilisation. Result: Overall, our study showed that exposure to any type of mass media was positively associated with making at least four ANC visits and PNC in two days. Women who listened to the radio at least once a week had higher odds of 4+ ANC visits (AOR 1.26, 95% CI: (1.07-1.49)), and receiving PNC in 48 hours (AOR 1.26, 95% CI: (1.01-1.57) than women who did not. Conclusion: Exposure to mass media is associated with maternal healthcare use in Zimbabwe. Mass media can potentially reach women in low-resource settings and encourage them to utilise maternal health services. The study recommends the development of mass media interventions and programs to increase awareness of maternal healthcare services. [Ethiop. J.

title: An Evaluation of How Repealing West Virginia’s Prevailing Wage Law Affected the Cost of Public Construction
Creators: name: Clark, Michael W.

description: This study compared school construction costs before and after legislative changes to prevailing wage laws in West Virginia. The study uses data provided by the School Building Authority of West Virginia (SBA). The data suggests that school construction costs increased in the years prior to the legislative changes and decreased after. Comparing projects bid with and without prevailing wages since 2013 suggests construction costs per square foot decreased by 7.3 percent since the removal of the wage requirement. However, the magnitude of the decrease depends on the time-period examined and the individual schools included in the analysis. States that border West Virginia did not experience similar decreases in the costs of school construction during this time.

description: Observations of very low-mass stars with Kepler represent an excellent opportunity to search for planetary transits and to characterize optical photometric variability at the cool end of the stellar mass distribution. In this paper, we present low-resolution red optical spectra that allow us to identify 18 very low-mass stars that have Kepler light curves available in the public archive. Spectral types of these targets are found to lie in the range dM4.5--dM8.5, implying spectrophotometric distances from 17 pc to 80 pc. Limits to the presence of transiting planets are placed from modelling of the Kepler light curves. We find that the size of the planets detectable by Kepler around these small stars typically lie in the range 1 to 5 Earth radii within the habitable regions (P$\le$10 days). We identify one candidate transit with a period of 1.26 days that resembles the signal produced by a planet slightly smaller than the Moon. However, our pixel by pixel analysis of the Kepler data shows that the signal most likely arises from a background contaminating eclipsing binary. For 11 of these objects reliable photometric periods shorter than 7 days are derived, and are interpreted as rotational modulation of magnetic cool spots. For 3 objects we find possible photometric periods longer than 50 days that require confirmation. H$_α$ emission measurements and flare rates are used as a proxies for chromospheric activity and transversal velocities are used as an indicator of dynamical ages. These data allow us to discuss the relationship between magnetic activity and detectability of planetary transits around very low-mass stars. We show that Super-Earth planets with sizes around 2 Earth radii are detectable with Kepler around about two thirds of the stars in our sample, independently from their level of chromospheric activity.

description: We present the results of an analysis of data collected by IceCube/DeepCore in 2010-2011 resulting in the first significant detection of neutrino oscillations in a high-energy neutrino telescope. A low-energy muon neutrino sample (20-100 GeV) containing the oscillation signal was extracted from data collected by DeepCore. A high-energy muon neutrino sample (100 GeV -10 TeV) was extracted from IceCube data in order to constrain the systematic uncertainties. The non-oscillation hypothesis was rejected with more than $5σ$. We fitted the oscillation parameters $Δm^2_{23}$ and $\sin^22 θ_{23}$ to these data samples. In a 2-flavor formalism we find $Δm^2_{23}= (2.5\pm0.6)\cdot10^{-3}$ eV$^2$ and $\sin^22 θ_{23}>0.92$ while maximum mixing is favored. These results are in good agreement with the world average values.

description: Abstract Background: Water-borne diseases are becoming more common because of inadequate water treatment procedures and unsanitary conditions. Aim: This study involved performing comparative microbial analyses at five different sites to assess the presence of enteric bacteria in the soil and groundwater used by poultry farms. Methods: Groundwater and soil samples obtained from four rural communities in Ijebu North region, Nigeria, were investigated using physicochemical and bacteriological analysis. Following the dilution plating method, enteric bacteria species were identified and characterized with the aid of colonial characteristics, gram-stain reaction, and biochemical tests Results: The findings demonstrated high contamination of groundwater sources in these communities, the presence of enteric bacteria including Salmonella species (38%), Escherichia coli (27%), Klebsiella species (9%), Staphylococcus species (4%) and Shigella species (22%) were reported in water samples, soil sample analysis also revealed the presence of Enteric bacteria including Salmonella species (47%), Escherichia coli (24%), Klebsiella species (5%), Staphylococcus species (5%) and Shigella species (19%). Conclusion: The analysis of water and soil samples provided strong evidence that soil can contaminate groundwater on poultry farms with enteric bacteria. To reduce the risk of enteric bacteria present, appropriate precautions such as proper poultry water treatment should be followed. [Ethiop. J.

description: We present photometric reverberation mapping of the narrow-line Seyfert 1 galaxy ESO399-IG20 performed with the robotic 15 cm telescope VYSOS-6 at the Cerro Armazones Observatory. Through the combination of broad- and narrow-band filters we determine the size of the broad-line emitting region (BLR) by measuring the time delay between the variability of the continuum and the H_alpha emission line. We use the flux variation gradient method to separate the host galaxy contribution from that of the active galactic nucleus (AGN), and to calculate the 5100A luminosity L_AGN of the AGN. Both measurements permit us to derive the position of ESO399-IG20 in the BLR size -- AGN luminosity R_BLR-L_AGN^0.5 diagram. We infer the basic geometry of the BLR through modelling of the light curves. The pronounced sharp variability patterns in both the continuum and the emission line light curves allow us to reject a spherical BLR geometry. The light curves are best fitted by a disk-like BLR seen nearly face-on with an inclination angle of 6+/-3 degrees and with an extension from 16 to 20 light days.

description: Comparisons were made between 55 heterosexual males, 49 heterosexual females, 56 homosexual males, and 35 homosexual females on measures of attachment, relationship satisfaction and relationship success. Results indicated that adult homosexuals experience greater difficulty than adult heterosexuals in becoming close to others. Individuals endorsing the secure attachment style reported greater relationship satisfaction than individuals endorsing either of the two insecure attachment styles. In addition, females reported greater relationship satisfaction than males. Significantly more individuals endorsing the secure attachment style reported their mothers to have been warm/responsive; significantly more heterosexual males and females than homosexual females reported their mothers to have been warm/responsive; significantly more homosexual males than homosexual females reported their fathers to have been cold/rejecting. A discussion of the findings and suggestions for future research are given.
