description: The empirical evidence for an upper mass limit for the red supergiant (RSG) progenitors of the Type II-P SNe at about 18 Msun, raises questions about the fate of the most luminous, most massive RSGs. These stars may evolve back to warmer temperatures to end their lives as hotter stars or collapse directly to black holes. The yellow hypergiants, many with extensive circumstellar dust and high mass loss, are excellent candidates for post-RSG evolution. We have identified six high luminosity yellow supergiants (YSGs) in the LMC with circumstellar dust including two of the FYPS (Dorn et al, 2022). We discuss their SEDs, mass lost and mass loss rates. Together with three additional FYPS, these nine stars are about 1/3 of the YSGs above 10^5 Lsun. We conclude that the high luminosity YSGs with surface pulsations and circumstellar dust, distinct from other YSGs, are candidates for post-RSG evolution in the LMC.

description: Background: ANC plays an important role in reducing maternal mortality and morbidity by detecting early risk factors in order to have an effective intervention in time and by linking the pregnant women to a planned delivery with a skilled birth attendant. Quality Antenatal care service can save the life of many pregnant mothers. Understanding quality of antenatal care in a health facility may be important for improvement of the service that could increase utilization of facility delivery. Objective of the study: To assess the quality of antenatal care and its association on intention to deliver in public health facility among ANC service utilizes in Bishoftu town. Method: Cross- sectional study supplemented by qualitative method was done at four public health facility found in Bishoftu town. Data was collected by using questionnaires at exit interview of clients, on provider competency and facility supply. Observational check list was used for provider performance. The study was conducted among 352 mothers who come for antenatal care service at the facility and health professional working at ANC clinic. The data was cleaned and analyzed by using statistical soft ware SPSS version 21. Result:-This study showed that overall satisfaction of client was as high as 84.9%. The satisfaction of women with secondary educational level was lesser than illiterate pregnant women (AOR = 0.32; 95 % CI, 0.11, 0.93).Others those who were poorly satisfied were because of long weighting time to get the service. This study also showed that higher proportion of health care providers were provide proper advice and information related to complications can occur during pregnancy. Health facilities have basic structural and medical equipments which was important to give ANC service. This study showed that pregnant women getting satisfaction on ANC service have great willingness and intention to give birth at health facility. Conclusions:-Overall satisfaction of antenatal care is high most of health care providers give Proper antenatal care service and health facilities were equipped with essential medical equipment and drugs for ANC service provision. Recommendation: To increase the ANC service satisfaction it is important to decrease waiting time at facility to get service. It is important to increase number of health care provider and extra room for ANC service provision and to improve service on recording and registration room.

description: The presence of hydrogen traps within a metallic alloy influences the rate of hydrogen diffusion. The electro-permeation (EP) test can be used to assess this: the permeation of hydrogen through a thin metallic sheet is measured by suitable control of hydrogen concentration on the front face and by recording the flux of hydrogen that exits the rear face. Additional insight is achieved by the more sophisticated three stage EP test: the concentration of free lattice hydrogen on the front face is set to an initial level, is then dropped to a lower intermediate value and is then restored to the initial level. The flux of hydrogen exiting the rear face is measured in all three stages of the test. In the present study, a transient analysis is performed of hydrogen permeation in a three stage EP test, assuming that lattice diffusion is accompanied by trapping and de-trapping. The sensitivity of the three stage EP response to the depth and density of hydrogen traps is quantified. A significant difference in permeation response can exist between the first and third stages of the EP test when the alloy contains a high number density of deep traps.

description: Asteroids smaller than about 100 meters are observed to rotate very fast, with periods often much shorter than the critical limit of 2.2 h. Some of these super-fast rotators can also achieve a very large semi-major axis drift induced by the Yarkovsky effect, that in turn, is determined by internal and surface physical properties. We consider the small super-fast rotating near-Earth asteroid 2016 GE1. This object rotates in just 34 seconds, and a large Yarkovsky effect has been determined from astrometry. Here we aim to constrain the thermal inertia of the surface of this extreme object. We used a recently developed statistical method to determine the thermal properties of near-Earth asteroids. The method is based on the comparison between the observed and the modelled Yarkovsky effect, and the thermal conductivity (inertia) is determined by a Monte Carlo approach. Parameters of the Yarkovsky effect model are either fixed if their uncertainty is negligible, modelled with a Gaussian distribution of the errors if they are measured, or deduced from general properties of the population of near-Earth asteroids when they are unknown. Using a well-established orbit determination procedure, we determined the Yarkovsky effect on 2016 GE1, and verified a significant semi-major axis drift rate. Using a statistical method, we showed that this semi-major axis drift rate could be explained only by low thermal inertia values below 100 J m$^{-2}$ K$^{-1}$ s$^{-1/2}$: namely, 90\% of the probability density function of the model outcomes is contained at values smaller than 100 J m$^{-2}$ K$^{-1}$ s$^{-1/2}$. We propose two possible interpretations for the extremely low values: a high porosity or a cracked surface, or a thin layer of fine regolith on the surface. Though this seems unexpected in either case, it opens up the possibility of a subclass of low thermal inertia, super-fast rotating asteroids.

description: Loop extrusion by motor proteins mediates the attractive interactions in chromatin on the length scale of megabases, providing the polymer with a well-defined structure and at the same time determining its dynamics. The mean square displacement of chromatin loci varies from a Rouse-like scaling to a more constrained subdiffusion, depending on cell type, genomic region and time scale. With a simple polymeric model, we show that such a Rouse-like dynamics occurs when the parameters of the model are chosen so that contacts are local along the chain, while in presence of non-local contacts, we observe subdiffusion at short time scales with exponents smaller than 0.5. Such exponents are independent of the detailed choice of the parameters and build a master curve that depends only on the mean locality of the resulting contacts. We compare the loop-extrusion model with a polymeric model with static links, showing that also in this case only the presence of nonlocal contacts can produce low-exponent subdiffusion. We interpret these results in terms of a simple analytical model.

description: One of the great triumphs in the history of numerical methods was the discovery of the Conjugate Gradient (CG) algorithm. It could solve a symmetric positive-definite system of linear equations of dimension N in exactly N steps. As many practical problems at that time belonged to this category, CG algorithm became rapidly popular. It remains popular even today due to its immense computational power. But despite its amazing computational ability, mathematics of this algorithm is not easy to learn. Lengthy derivations, redundant notations, and over-emphasis on formal presentation make it much difficult for a beginner to master this algorithm. This paper aims to serve as a starting point for such readers. It provides a curt, easy-to-follow but minimalist derivation of the algorithm by keeping the sufficient steps only, maintaining a uniform notation, and focusing entirely on the ease of reader.

description: The added value of the use of augmented reality in various cognitive educational fields as well as the limited research based on studies in Literature, demonstrated the need to typeset this work. Its main purpose is to propose a new approach to the teaching of poetry in secondary education, through mobile devices, such as are phones, tablets, that will make use of Augmented Reality technology. For this purpose, the application, ARPoetry, was created through the Unity Platform, with the help of which specific poems with audio, image, video, text or 3D model files were augmented. Specifically, the application was based on cards with the quick response code printed (QRcode). Finally, this particular application was given to teachers who teach poetry to evaluate it. Regarding the evaluation, the usability of the AR application was checked and it was stated that the application is easy to use and will be potentially used by teachers for teaching poetry. Of course, a satisfactory percentage stated that they will need help to be able to use this application which indicates their reticence about its wide functionality.

description: We study the loosely bound Skyrme model with the addition of two different pion mass terms; this is the most general potential of polynomial form up to second order in the trace of the Skyrme field. The two pion mass terms are called the standard pion mass term and the modified pion mass term. We find that the binding energies are not reduced by the introduction of the modified pion mass, but it is analogous to the standard pion mass term with a decrease in the value of the mass parameter of the loosely bound potential (for large values of the latter parameter). We find by increasing the overall pion mass that we can reduce the classical binding energy of the 4-Skyrmion to the 2.7% level and the total binding energy including the contribution from spin/isospin quantization is reduced to the 5.8% level.

Assessment of the Management and Contribution of Special Pharmacies to Health Care Financing in West Shoa Zone of Oromia National Regional State
Creators: name: Refissa, Abera
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2006

description: Low income developing countries have started reforming their health care deliveries and health care financing systems. One of the components of health care financing reforms is cost – recovery mechanism. A Bamako Initiative Revolving Drug Fund system is a cost-recovery mechanism which has been adopted by many developing countries. Ethiopia is one of the low income Sub-Saharan African countries which have adopted BI RDF system of cost-recovery mechanism to improve its health care financing which is crucial in improving health service delivery. In West Shoa Zone five special pharmacies were established in five health facilities to generate more revenue to finance health care service deliveries. A cross-sectional health facility based assessment was conducted from January 2006 to March 2006 in West Shoa to assess the organizational management of the special pharmacy schemes, the drugs and supplies management in the special pharmacies, the financial contribution of the revenue of the special pharmacies to the other health programs in the health facilities and the perceptions of the health professional about the contribution of the special pharmacies to the health facilities. What was found out from the assessment was poor organizational management system with no comprehensive activity, planning, organizing, executing and controlling. There were poor financial managements in all facilities and there were no financial statements, proper auditing and documentations. There were also very poor drugs and supplies management system and except in one health facility (Holota health center) there were no impressive contributions in health care financing. Community participations which are very determinant factors were not vii there and the involvement and participation of the health professionals in the health facilities were very limited. Therefore, based on the results of the assessments it is concluded that in all facilities the management of the special pharmacies must be well structured to act according to the guideline to attain the goals of the SPs, timely supportive supervisions from concerned bodies, community participation should prevail and sound participation of the health professionals in the activities of the special pharmacies is necessary.

description: The characteristic orbital period of the inner-most objects within the galactic census of planetary and satellite systems appears to be nearly universal, with $P$ on the order of a few days. This paper presents a theoretical framework that provides a simple explanation for this phenomenon. By considering the interplay between disk accretion, magnetic field generation by convective dynamos, and Kelvin-Helmholtz contraction, we derive an expression for the magnetospheric truncation radius in astrophysical disks, and find that the corresponding orbital frequency is independent of the mass of the host body. Our analysis demonstrates that this characteristic frequency corresponds to a period of $P\sim3$ days, although intrinsic variations in system parameters are expected to introduce a factor of $\sim2-3$ spread in this result. Standard theory of orbital migration further suggests that planets should stabilize at an orbital period that exceeds disk truncation by a small margin. Cumulatively, our findings predict that the periods of close-in bodies should span $P\sim2-12$ days - a range that is consistent with observations.

description: Background: Our ability to optimize the care of older adults with cancer and comorbid illnesses is insufficient because most clinical trials lack systematic measurement. The primary purpose of this study was to evaluate the association between patient-reported comorbidity and all-cause mortality using various comorbidity scoring algorithms. Materials and Methods: The Carolina Senior Registry was linked with the North Carolina Central Cancer Registry to obtain mortality data. Comorbidity was assessed using the patient-reported Older Americans Resources and Services Questionnaire subscale that assesses 13 specific conditions and the degree to which each impairs activities. Multivariable Cox proportional hazard regression models were used to evaluate the association between comorbidities and all-cause mortality. Results: The study sample included 539 patients; the median age was 72 years, 72% were female, and 47% had breast cancer. Overall, 92% reported ≥1 comorbid condition, with a mean of 2.7 conditions (range 0–10), with arthritis and hypertension the most common (52% and 50%, respectively). Approximately 60% reported a functional limitation related to comorbidity. After adjusting for time from diagnosis to geriatric assessment, age, cancer type, and stage, the risk of death increased by 5% for each unit increase in comorbidity burden score (adjusted hazard ratio [HR] = 1.05, 95% confidence interval [CI]: 1.01–1.10) and 12% for each comorbid condition impacting function (HR = 1.12, 95% CI: 1.02–1.23). Conclusion: Comorbid conditions in older adults with cancer are highly prevalent and associated with all-cause mortality, particularly those conditions that impair function. Routine comorbidity assessment should be included in clinical trials and can be measured via a simple one-page patient-reported questionnaire. Implications for Practice: In order to optimize and personalize the care of older adults with cancer, systematic measurement of comorbidities is necessary in both clinical trials and routine practice. Patient-reported comorbid conditions in older adults with cancer are highly prevalent and are associated with increased risk of all-cause mortality, particularly for those conditions that impair function. Comorbidity can be systematically measured via a one-page patient-reported questionnaire and should be incorporated into future clinical trials and considered for use in oncology clinics to aid in assessing older adults with cancer.

description: A number of transition disks exhibit significant azimuthal asymmetries in thermal dust emission. One possible origin for these asymmetries is dust trapping in vortices formed at the edges of dead zones. We carry out high-resolution, two-dimensional hydrodynamic simulations of this scenario, including the effects of dust feedback. We find that, although feedback weakens the vortices and slows down the process of dust accumulation, the dust distribution in the disk can nonetheless remain asymmetric for many thousands of orbits. We show that even after $10^4$ orbits, or $2.5$ Myr when scaled to the parameters of Oph IRS 48 (a significant fraction of its age), the dust is not dispersed into an axisymmetric ring, in contrast to the case of a vortex formed by a planet. This is because accumulation of mass at the dead zone edge constantly replenishes the vortex, preventing it from being fully destroyed. We produce synthetic dust emission images using our simulation results. We find that multiple small clumps of dust may be distributed azimuthally. These clumps, if not resolved from one another, appear as a single large feature. A defining characteristic of a disk with a dead zone edge is that an asymmetric feature is accompanied by a ring of dust located about twice as far from the central star.

description: Background: Food borne illnesses are prevalent in all parts of the world. However, number of related problems keep food borne diseases at high levels within the African Region, the root cause is poverty, which exacerbates food safety problems in many ways and contributes to unsanitary conditions in rapidly growing urban centers, lack of access to clean water, unhygienic transportation and storage of foods. Just like many other African countries, food borne illnesses are prevalent in Ethiopia and the loss of human life and suffering is enormous. Objective: The purpose of this study was to assess the sanitary condition of food catering establishment in Addis Ketema Sub-City, Addis Ababa City Administration. Methods: A cross sectional study was conducted from March to April 2014 at different Food catering establishments in Addis Ababa city Administration Addis Ketema Sub-City selected by using Stratified random sampling method followed by population proportion to size allocation. Three hundred fifty two establishments were enrolled in this study. Microbiological tests of food utensils were conducted using standard laboratory procedures. The collected data was cleaned and entered by developing a template using Epi info 3.5.3 and the sanitary condition of food catering establishments were analyzed by using SPSS version 16 Software. Results: Latrine facilities were available in 297 (84.6%) catering food establishments. However, the toilets were not separately constructed from kitchen room. 234 (66.7%) of the kitchens had access to running tap water inside the facility. Conventional types of sinks fixed with running tap water were available in 245(69.8%) of the catering food establishments. Of the examined food utensils for bacteriologic content. Staphylococcus aureus were found in 14(36.8%), Escherichia Coli in 6 (15.8%) and 4(10.5%) Shigella species were found from the swabbed utensils Conclusion and recommendation: The sanitary condition of catering food establishments in the study area were found to have poor sanitation and were not fulfil the requirements of catering food establishments. Appropriate regular inspection of food catering establishment should be strengthening by regulatory body Sub-City and Woreda health to the fulfilment of catering food establishments to acceptable sanitary conditions.

description: Theoretical consideration of the propagation of femtosecond-Gaussian pulses in a 1D composite medium, consisting of alternating self-focusing (SF) and self-defocusing (SDF) waveguide segments with normal group-velocity dispersion predicts the generation of trains of bright solitons when an optical pulse first propagates in the SF segment, followed by the SDF one. The multiple temporal compression (MTC) process, based on this setting, offers a method for controllable generation of multiple ultrashort temporal solitons. Numerical solutions of the generalized nonlinear Schrödinger equation modeling this system demonstrate that the intrapulse Raman scattering plays a major role in the temporal and spectral dynamics. Collisions between ultrashort solitons with different central wavelengths are addressed too. The paper provides, for the first time, a procedure for producing controllable trains of ultrashort temporal solitons by incident optical pulses propagating in a composite medium.

description: We study the effect of thermal blurring caused by the use of (momentum-space) rapidity as a proxy of coordinate-space rapidity in experimental measurements of conserved charge fluctuations in relativistic heavy ion collisions. In theoretical studies assuming statistical mechanics, calculated fluctuations are those in a spatial volume. Experiments, on the other hand, can measure fluctuations only in a momentum-space in the final state. In a standard argument to compare experimental results for a momentum space with theoretical studies for a coordinate space, rapidities of particles are implicitly regarded as equivalent to their coordinate-space rapidity. We show that the relation of two fluctuations is significantly altered by the existence of the thermal motion, i.e. thermal blurring. We discuss that the thermal blurring can be regarded as a part of the diffusion process, and the effect can be understood by studying the rapidity window dependences of fluctuations. Centrality dependence of the thermal blurring effect is also discussed.

Variables with p-value <0.2 in the bivariate analysis were entered in to multivariate analysis and with p-value <0.05 in the final model were considered as significant. Results: Occupational injuries in the past 12 months were reported by 34.9% (1.65± 0.48) of workers. The most common body parts injured were lower and upper limbs (73.3% and16%). The majority of injuries were puncture/cuts/lacerations (75%) and contusions (22.1%). Walking on/Handling of sharp objects (61.4%), falls (10.7%) and injuries by manual tools (10.7%) were the main causes of injuries. All of injured workers (100%) reported complete recovery. Extended working hours, job dissatisfaction, not using PPE, substance usage and job stress were predictors of occupational injuries. Conclusion: Non-fatal occupational injuries are common among this sample of construction workers with significant relation to extended working hours and job stress and other risk factors. So, workers training and orientation to raise safety awareness and consciousness to improve safety practices, effective communication between management and workers, general housekeeping and falls protections should be fulfilled.

description: Exchange coupling in an interfacial context is crucial for spin-torque nano oscillator (STNO) that consists of a non-magnetic spacer which is alloyed with a ferromagnetic material. Currently, investigations on the dynamics of the free layer magnetization and frequency enhancement in the STNO with bilinear coupling are still being actively pursued. In the present work, we investigate the dynamics of the STNO in the presence of bilinear coupling but in the absence of an external magnetic field by analyzing the associated Landau-Lifshitz-Gilbert-Sloncewski(LLGS) equation, and consequently the impact of the bilinear coupling on the dynamics of the magnetization of the free layer is studied. It is observed that the frequency of the oscillations in the magnetization component along the direction of the pinned layer polarization can be enhanced above 300 GHz by positive bilinear coupling and up to around 30 GHz by negative bilinear coupling. We further reveal a transition from in-plane to out-of-plane precession both for positive and negative bi-linear couplings. We also analyze the switching of the magnetization for different values of current and bilinear coupling. Our detailed investigations of STNO with bilinear coupling aim at the possibilities of high-frequency devices by considering the applied current and bilinear coupling in the absence of a magnetic field.

description: Background: Older adults are often exposed to multiple medications, some of which could be inappropriate or have the potential to interact with each other. Older cancer patients may be at increased risk for medication-related problems due to exposure to cancer-directed treatment. Methods: We described patterns of potentially inappropriate medication (PIM) use and potential drug-chemotherapy interactions among adults age 66+ years diagnosed with stage I-III breast, stage II-III colon, and stage I to II lung cancer. Within the Surveillance, Epidemiology, and End Results-Medicare database, patients had to have Medicare Part D coverage with 1+ prescription in the diagnosis month and Medicare Parts A/B coverage in the prior 12 months. We estimated monthly prevalence of any and cancer-related PIM from 6 months pre- to 23 months post-cancer diagnosis and 12-month period prevalence of potential drug- chemotherapy interactions. Results: Overall, 19,318 breast, 7,283 colon, and 7,237 lung cancer patients were evaluated. Monthly PIM prevalence was stable prediagnosis (37%-40%), but increased in the year following a colon or lung cancer diagnosis, and decreased following a breast cancer diagnosis. Changes in PIM prevalence were driven primarily by cancer-related PIM in patients on chemotherapy. Potential drug-chemotherapy interactions were observed in all cohorts, with prevalent interactions involving hydrochlorothiazide, warfarin, and proton-pump inhibitors. Conclusions: There was a high burden of potential medication-related problems among older cancer patients; future research to evaluate outcomes of these exposures is warranted. Impact: Older adults diagnosed with cancer have unique medication management needs. Thus, pharmacy specialists should be integrated into multidisciplinary teams caring for these patients.
Self-force corrections to the periapsis advance around a spinning black hole

description: The linear in mass ratio correction to the periapsis advance of equatorial orbits around a spinning black hole is calculated for the first time and to very high precision, providing a key benchmark for different approaches modelling spinning binaries. The high precision of the calculation is leveraged to discriminate between two recent incompatible derivations of the 4PN equations of motion. Finally, the limit of the periapsis advance near the innermost stable orbit (ISCO) allows determination of the ISCO shift, validating previous calculations using the first law of binary mechanics. Calculation of the ISCO shift is further extended into the near extremal regime (with spins up to $1-a=10^{-20}$), revealing new unexpected phenomenology. In particular, we find that the shift of the ISCO does not have a well defined extremal limit, but instead continues to oscillate.

description: Last complete novel completed by Charles Dickens and is one of his most sophisticated works, combining savage satire with social analysis. In the opening chapters a body is found in the Thames and identified as that of John Harmon, a young man recently returned to London to receive his inheritance. Were he alive, his father's will would require him to marry Bella Wilfer, a beautiful, mercenary girl whom he had never met. Instead, the money passes to the working-class Boffins, and the effects spread into various corners of London society. Issued monthly from May 1864 to November 1865 in illustrated green paper covers.

description: Introduction: Solid waste collection is a daily task all over the world with significant variation in its amount and type. Waste is automatically regarded as the harbinger of disease and the bringer of illness. Inadequate understanding of magnitude of the problem & poor financial resources, occupational risk behaviors of waste collectors is major problems in most of developing countries. Ethiopia as one of the developing countries, municipal solid waste is collected manually and lifting, carrying, pulling, pushing, and loading it is a common task. Objective: This study aimed at assessing health risk protection behaviors, knowledge, attitude and practice among solid waste collectors in Addis Ababa city. Method: A cross sectional survey complemented by qualitative key in-depth interview was carried out among solid waste collectors working as home to home waste collectors under small scale enterprise unions at Addis Ababa city administration. Sample populations were selected using multi stage sampling technique. A total of 654 solid waste collectors and 2 woreda solid waste management heads and 3 supervisors were interviewed from February to March, 2015. Data was entered into a computer by using Epi-Info version 3.5.1and analyzed using SPSS version 20 for windows. Frequencies, means, tables and graphs were used to present data. Logistic regression analysis was used in order to identify the association between predictor variables and dependent variable and to control confounders. Thematic analysis using open code soft ware was used for qualitative data analysis. Result: The response rate of this study was 98.2% and male respondent were 60.7%. The median age of the study subjects was 29 ranging from 18 to 68 years. Above half of SWC had low level of knowledge (52%) in term of alertness, positive attitude (53.7%) about health risk protection and inappropriate practice (55.5%) on prevention of infections, injury and disability. Training on occupational health safety were associated significantly with both frequently hand wash and wearing PPE during duty (AOR=2.41; 95% CI, 1.47-3.96 and AOR=1.77; 95% CI, 1.21-2.61) respectively. Lack of concern, addiction, carelessness, lack of PPE supply and nature of job were reasons mentioned for SWC health risk practice. Conclusion and Recommendation: Health risk protection behavior among solid waste collectors in Addis Ababa city was inappropriate. Solid waste collectors should be packaged in health related programs to enhance their health care information and health service utilization. Training SWC about safety and provision of standardized PPE is highly recommended.
