Assessment of Healthcare Waste Generation Rate, Composition and Its Management System in Menellik Ii Referral Hospital, Addis Ababa, Ethiopia
Creators: name: Debalkie, Desta
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Background: Healthcare facilities provide health service and prevent the public from health risk such as communicable disease. However, hospitals by virtue of handling patients generate hazardous waste which is potentially harmful to the environment if not handled and disposed properly. The amount and type of waste generated from the healthcare facilities is not well documented and managed in Ethiopia. Objective: The objective of this study is to assess the health care waste generation rate, composition and its management system in Menellik II referral hospital, Addis Ababa. Methods: An institutional based descriptive cross-sectional study design using both quantitative and qualitative methods was employed to assess the waste generation rate and management system in Menellik II referral hospital in Addis Ababa City. Standard weighing scale was used to quantify the generation rate of healthcare waste for seven days and observational check list for participatory walk through survey. The key informant interview guide also conducted to assess healthcare waste management practice. Data collectors and supervisor were recruited and trained. Data was entered in to Microsoft office excel version 2007 and transported to SPSS version 20 for analysis. Mean generation rates were determined based on important factors, the type of case teams. Patient flow, healthcare waste and its type generation rate among case teams were compared using Kruskal Wallis test and relation of visitors and amount of healthcare waste were determined by Pearson correlation. Results: The mean waste generation rate was found to be 1.94 Kg/bed/day±0.335, comprised of 40.9% general and 59.1% hazardous wastes. The amount of waste generated was significantly increased as the number of patient flow increased (r=0.835, p<0.05). Inpatients generated high proportion of total healthcare wastes than outpatient case teams (t=4.353, p<0.01). The mean waste generation rate was significantly varied among case teams (X2=56.558, p<0.0001). The staff wrong attitude, resistance to wards waste segregation, collection and treatment practice, and lower managerial commitment resulted in poor healthcare waste management system. Conclusions: The mean generation rate in the hospital is comparable to other studies in Ethiopia but higher than Sub Saharan African countries and the management of healthcare waste was poor. The composition of hazardous waste was 1.5 that of general waste (t=2.8, P<0.05) and the generations vary with patient load. The hospital should audit generation of waste to develop and implement effective and efficient waste management systems and conduct periodical surveillance of health care waste management practices.

description: We analyze the physical properties of 8 X-ray selected active galactic nuclei (AGN) and one candidate protoquasar system (ADF22A1) in the $z = 3.09$ SSA22 protocluster by fitting their X-ray-to-IR spectral energy distributions (SEDs) using our SED fitting code, Lightning. We recover star formation histories (SFH) for 7 of these systems which are well-fit by composite stellar population plus AGN models. We find indications that 4/9 of the SSA22 AGN systems we study have host galaxies below the main sequence, with $\rm SFR/SFR_{MS} \leq -0.4$. The remaining SSA22 systems, including ADF22A1, are consistent with obscured supermassive black hole (SMBH) growth in star forming galaxies. We estimate the SMBH accretion rates and masses, and compare the properties and SFH of the 9 protocluster AGN systems with X-ray detected AGN candidates in the Chandra Deep Fields (CDF), finding that the distributions of SMBH growth rates, star formation rates, SMBH masses, and stellar masses for the protocluster AGN are consistent with field AGN. We constrain the ratio between the sample-averaged SSA22 SMBH mass and CDF SMBH mass to $<1.41$. While the AGN are located near the density peaks of the protocluster, we find no statistically significant trends between the AGN or host galaxy properties and their location in the protocluster. We interpret the similarity of the protocluster and field AGN populations together with existing results as suggesting that the protocluster and field AGN co-evolve with their hosts in the same ways, while AGN-triggering events are more likely in the protocluster.

description: It has recently been shown that if the dark matter is in thermal equilibrium with a sector that is highly decoupled from the Standard Model, it can freeze-out with an acceptable relic abundance, even if the dark matter is as heavy as ~1-100 PeV. In such scenarios, both the dark and visible sectors are populated after inflation, but with independent temperatures. The lightest particle in the dark sector will be generically long-lived, and can come to dominate the energy density of the universe. Upon decaying, these particles can significantly reheat the visible sector, diluting the abundance of dark matter and thus allowing for dark matter particles that are much heavier than conventional WIMPs. In this paper, we present a systematic and pedagogical treatment of the cosmological history in this class of models, emphasizing the simplest scenarios in which a dark matter candidate annihilates into hidden sector particles which then decay into visible matter through the vector, Higgs, or lepton portals. In each case, we find ample parameter space in which very heavy dark matter particles can provide an acceptable thermal relic abundance. We also discuss possible extensions of models featuring these dynamics.

description: The variability of submillimeter emission provides a useful tool to probe the accretion physics in low-luminosity active galactic nuclei. We accumulate four years of observations using Submillimeter Array for Centaurus A, NGC 4374, NGC 4278, and NGC 5077 and one year of observations for NGC 4552 and NGC 4579. All sources are variable. We measure the characteristic timescale at which the variability is saturated by modeling these sources' light curve as a damped random walk. We detect a timescale for all the sources except NGC 4552. The detected timescales are comparable to the orbital timescale at the event horizon scale for most sources. Combined with previous studies, we show a correlation between the the timescale and the black hole mass over three orders of magnitude. This discovery suggests the sub-mm emission is optically thin with the emission originating from the event horizon. The mass scaling relationship further suggests that a group of radio sources with a broadband spectrum that peaks at submillimeter wavelengths have similar inner accretion physics. Sources that follow this relationship may be good targets for high-resolution imaging with the Event Horizon Telescope.

description: The purpose of this thesis is to investigate the role of hypertext in the cultural articles “Der Spiegel” magazine. In order to fulfil this purpose, a triple analysis is followed in the empirical part of the thesis: A Critical Discourse Analysis, a hypertext analysis and a comparison between the corresponding printed version of each hypertext, with view to demonstrate the hypertextual characteristics and identify any discrepancies between the two different forms of the same article. Various research issues are addressed, such as the definition of the hypertext, its relationship with Cultural Journalism, the possibilities it offers, etc. In addition, extensive references are included about Cultural Journalism, Critical Discourse Analysis and the philosophy of “Der Spiegel” magazines in general and its cultural articles in particular. Therefore, based on the above, the research which was developed in the context of this thesis makes an effort to answer the three following questions: Which is the role of the hypertext in Spiegel's cultural articles? Which is the relationship between cultural articles with socio-political issues, history and current affairs? Which are the differences between the printed and hypertextual form of the same article?
Does Nature allow formation of ultra-compact black hole X-ray binaries via accretion-induced collapse of neutron stars?

description: The formation path to ultra-compact X-ray binaries (UCXBs) with black hole (BH) accretors is still unclear. In the classical formation scenario, it is difficult to eject the massive envelope of the progenitor star of the BH via common envelope process. Given that some neutron stars (NSs) in binary systems evidently have birth masses close to $\sim 2.0\;M_\odot$, we explore here the possibility that BH-UCXBs may form via accretion-induced collapse (AIC) of accreting NSs, assuming that these previously evolved in LMXBs to masses all the way up to the maximum limit of a NS. We demonstrate this formation path by modelling a few cases of NS-UCXBs with initial NS masses close to the maximum mass of a NS that evolve into BH-UCXBs after the NS accretes material from its He~WD companion. We follow the evolution of the post-AIC BH-UCXB and, based on simple arguments, we anticipate that there is about one BH-UCXB with an AIC origin and a He~WD donor within the current sample of known UCXBs and that 2--5 such BH-UCXBs may be detected in gravitational waves by LISA. In addition, we find that the X-ray luminosity of NS-UCXBs near their orbital period minimum exceeds $\sim 10^{39}\;{\rm erg\;s^{-1}}$ and thus such systems may appear as ultraluminous X-ray sources.

description: We propose a multi-component generalization of the modified short pulse (SP) equation which was derived recently as a reduction of Feng's two-component SP equation. Above all, we address the two-component system in depth. We obtain the Lax pair, an infinite nember of conservation laws and multisoliton solutions for the system, demonstrating its integrability. Subsequently, we show that the two-component system exhibits cusp solitons and breathers for which the detailed analysis is performed. Specifically, we explore the interaction process of two cusp solitons and derive the formula for the phase shift. While cusp solitons are singular solutions, smooth breather solutions are shown to exist, provided that the parameters characterizing the solutions satisfy certain condition. Last, we discuss the relation between the proposed system and existing two-component SP equations.

description: The Gaia-ESO survey recently reported on a large sample of lithium (Li) abundance determinations for evolved stars in the rich open cluster Trumpler 20. They argue for a scenario where virtually all stars experience post main sequence mixing and Li is preserved in only two objects. We present an alternate explanation, where Li is normal in the vast majority of cluster stars and anomalously high in these two cases. We demonstrate that the Li upper limits in the red giants can be explained with a combination of main sequence depletion and standard dredge-up, and that they are close to the detected levels in other systems of similar age. In our framework, the two detected giants are anomalously Li-rich, and we propose that both could have been produced by the engulfment of a substellar mass companion of 16(+6-10) M_J. This would imply that ~5% of 1.8 solar mass stars in this system, and by extension elsewhere, should have substellar mass companions of high mass that could be engulfed at some point in their lifetimes. We discuss future tests that could confirm or refute this scenario.

description: We consider a real, massive scalar field on ${\rm PAdS}_{d+1}$, the Poincaré domain of the $(d+1)$-dimensional anti-de Sitter (AdS) spacetime. We first determine all admissible boundary conditions that can be applied on the conformal boundary, noting that there exist instances where "bound states" solutions are present. Then, we address the problem of constructing the two-point function for the ground state satisfying those boundary conditions, finding ultimately an explicit closed form. In addition, we investigate the singularities of the resulting two-point functions, showing that they are consistent with the requirement of being of Hadamard form in every globally hyperbolic subregion of ${\rm PAdS}_{d+1}$ and proposing a new definition of Hadamard states which applies to ${\rm PAdS}_{d+1}$.

description: Low mass stars ($\leq 1$ M$_{\odot}$) are some of the best candidates for hosting planets with detectable life because of these stars' long lifetimes and relative planet to star mass and radius ratios. An important aspect of these stars to consider is the amount of ultraviolet (UV) and X-ray radiation incident on planets in the habitable zones due to the ability of UV and X-ray radiation to alter the chemistry and evolution of planetary atmospheres. In this work, we build on the results of the HAZMAT I (Shkolnik & Barman 2014) and HAZMAT III (Schneider & Shkolnik 2018) M star studies to determine the intrinsic UV and X-ray flux evolution with age for M stars using Gaia parallactic distances. We then compare these results to the intrinsic fluxes of K stars adapted from HAZMAT V (Richey-Yowell et al. 2019). We find that although the intrinsic M star UV flux is 10 to 100 times lower than that of K stars, the UV fluxes in their respective habitable zone are similar. However, the habitable zone X-ray flux evolutions are slightly more distinguishable with a factor of 3 -- 15 times larger X-ray flux for late-M stars than for K stars. These results suggest that there may not be a K dwarf advantage compared to M stars in the UV, but one may still exist in the X-ray.

description: This thesis examined the use of TikTok videos as a platform for political education among overseas Filipino voters in Qatar during the May 2022 elections. With the increasing popularity and influence of social media in political discourse, this study aimed to explore the potential of TikTok as a tool for engaging and informing voters, particularly the overseas Filipino community residing in Qatar. Through an internet survey approach, data was collected from a sample of 1.5% registered voters in Qatar, focusing on their perception and behavioral intention towards using TikTok for political education. The study revealed optimistic perceptions among respondents, highlighting the effectiveness of TikTok's visual and interactive features in disseminating political information. However, the study also acknowledges limitations, including the small sample size and the need for further investigation into specific candidates or political parties. The research emphasizes the need for future studies to examine the influence of TikTok on voting patterns and expand the scope to include a larger sample size and multiple social media platforms.

Τα εμβόλια mRNA μπορεί να είναι είτε εμβόλια που προφυλάσσουν από ασθένειες, είτε θεραπευτικά.

description: Vaccines are one of the most important tools in public health and play an important role in controlling various kinds of diseases. Due to their accuracy, safety profile and flexible construction, mRNA vaccines are emerging as a new alternative to conventional vaccines. mRNA vaccines were the technology used by several companies to produce vaccines against the COVID-19 pandemic, where mRNA vaccines were administered globally for the first time. mRNA vaccines can be either disease-preventive or therapeutic. For this reason, they specialize in clinical studies to treat a wide range of diseases, including cancer, HIV, influenza, Ebola and many others. Therefore, mRNA vaccines are the innovation in the medical field to address these issues. This paper reviews the history of mRNA vaccines and describes areas of mRNA production and purification, methods by which mRNA is modified for optimal performance, delivery systems and routes of administration for best results, and analyzes preclinical and infectious disease trials, various types of cancer and for the COVID-19 pandemic. Finally, the perspectives that can lead to even better results in the future are mentioned.

description: In this paper, we consider Einstein gravity coupled to a vector field, either minimally or non-minimally, together with a vector potential of the type $V=2Λ_0+\ft 12 m^2 A^2+γ_4 A^4$. For a simpler non-minimally coupled theory with $Λ_0=m=γ_4=0$, we obtain both extremal and non-extremal black hole solutions that are asymptotic to Minkowski space-times. We study the global properties of the solutions and derive the first law of thermodynamics using Wald formalism. We find that the thermodynamical first laws of the extremal black holes are modified by a one form associated with the vector field. In particular, due to the existence of the non-minimal coupling, the vector forms thermodynamic conjugates with the graviton mode and partly contributes to the one form modifying the first laws. For a minimally coupled theory with $Λ_0\neq 0$, we also obtain one class of asymptotically flat extremal black hole solutions in general dimensions. This is possible because the parameters $(m^2,γ_4)$ take certain values such that $V=0$. In particular, we find that the vector also forms thermodynamic conjugates with the graviton mode and contributes to the corresponding first laws, although the non-minimal coupling has been turned off. Thus all the extremal black hole solutions that we obtain provide highly non-trivial examples how the first law of thermodynamics can be modified by a either minimally or non-minimally coupled vector field. We also study Gauss-Bonnet gravity non-minimally coupled to a vector and obtain asymptotically flat black holes and Lifshitz black holes.

description: Abuse by an intimate partner (marital or spousal abuse) and coercion are the two most globally prevalent forms of violence against women. However community based studies on this subject is limited. In Ethiopia there is also little research work in the area of physical partner violence. The objective of this study is to measure the magnitude of physical violence experienced by married women; men own use of physical violence, factors associated with experience of physical violence, its immediate outcomes and describe cultural and societal perspectives of partner violence. Community based cross sectional survey was conducted with complementary Focus Group Discussions in Kofele district, Arsi zone, Oromia region. Households were selected with systematic random sampling from randomly selected Peasant associations. Married adult men age 15 years and above & women aged 15-49 years, living in the households sampled were included in the study. A field-tested, structured and pre-tested questionnaire was used to collect the information for the quantitative study and semi-structured guideline was used for focus group discussions. A total of 400 men and 396 women participated in the study. The majority of the study participants (99.75 % of men and 94.7% of women) belong to Oromo ethnic group. About 64% and 55% of women had experienced physical violence in their life time and last 12months before survey respectively and 59% and 22% of men reported to use physical violence against their most recent partners in lifetime and last year respectively. Women's experience of partner physical violence is associated with presence of other person in the household (OR & 95%CI=0.6(0.39, 0.92), family history of violence( OR & 95% CI= 1.54( 1.01, 2.35), type of marital arrangement with current partner by abduction (OR & 95%CI= 3.96(1.58, 9.96) compared with those married with their agreement), number of children less than five years age in the house hold (OR & 95%CI=3.6 (1.9, 7.0) for only one child & 1.89(1.1, 3.8) for three or more children relative to no child in household), parity of women(OR & 95%CI=2.5(1.4, 4.7) for 4-7 births relative to 0-3 births) and belief about whether battering woman who failed to complete her household works is acceptable (OR & 95%CI=2.0 (1.1, 3.5) for agreeing with the situation ). Physical partner violence is very high in the study area and is associated with avoidable factors. There are also important cultural practices useful in protecting women from violence in this study population. This calls for immediate interventions that include education on gender roles, family relations and improving women's reproductive health and supporting structures for cases of violence and encouraging and maintaining supporting useful cultural practices.

description: We inspect the microlensing data of the KMTNet survey collected during the 2018--2020 seasons in order to find lensing events produced by binaries with brown-dwarf companions. In order to pick out binary-lens events with candidate BD lens companions, we conduct systematic analyses of all anomalous lensing events observed during the seasons. By applying the selection criterion with mass ratio between the lens components of $0.03\lesssim q\lesssim 0.1$, we identify four binary-lens events with candidate BD companions, including KMT-2018-BLG-0321, KMT-2018-BLG-0885, KMT-2019-BLG-0297, and KMT-2019-BLG-0335. For the individual events, we present the interpretations of the lens systems and measure the observables that can constrain the physical lens parameters. The masses of the lens companions estimated from the Bayesian analyses based on the measured observables indicate that the probabilities for the lens companions to be in the brown-dwarf mass regime are high: 59\%, 68\%, 66\%, and 66\% for the four events respectively.

description: Background: Financial relationships between physicians and the pharmaceutical industry are common, but factors that may determine whether such relationships result in physician practice changes are unknown. Materials and Methods: We evaluated physician use of orally administered cancer drugs for four cancers: prostate (abiraterone, enzalutamide), renal cell (axitinib, everolimus, pazopanib, sorafenib, sunitinib), lung (afatinib, erlotinib), and chronic myeloid leukemia (CML; dasatinib, imatinib, nilotinib). Separate physician cohorts were defined for each cancer type by prescribing history. The primary exposure was the number of calendar years during 2013–2015 in which a physician received payments from the manufacturer of one of the studied drugs; the outcome was relative prescribing of that drug in 2015, compared with the other drugs for that cancer. We evaluated whether practice setting at a National Cancer Institute (NCI)-designated Comprehensive Cancer Center, receipt of payments for purposes other than education or research (compensation payments), maximum annual dollar value received, and institutional conflict-of-interest policies were associated with the strength of the payment-prescribing association. We used modified Poisson regression to control confounding by other physician characteristics. Results: Physicians who received payments for a drug in all 3 years had increased prescribing of that drug (compared with 0 years), for renal cell (relative risk [RR] 1.81, 95% confidence interval [CI] 1.58–2.07), CML (RR 1.22, 95% CI 1.08–1.39), and lung (RR 1.69, 95% CI 1.58–1.82), but not prostate (RR 0.97, 95% CI 0.93–1.02). Physicians who received compensation payments or >$100 annually had increased prescribing compared with those who did not, but NCI setting and institutional conflict-of-interest policies were not consistently associated with the direction of prescribing change. Conclusion: The association between industry payments and cancer drug prescribing was greatest among physicians who received payments consistently (within each calendar year). Receipt of payments for compensation purposes, such as for consulting or travel, and higher dollar value of payments were also associated with increased prescribing. Implications for Practice: Financial payments from pharmaceutical companies are common among oncologists. It is known from prior work that oncologists tend to prescribe more of the drugs made by companies that have given them money. By combining records of industry gifts with prescribing records, this study identifies the consistency of payments over time, the dollar value of payments, and payments for compensation as factors that may strengthen the association between receiving payments and increased prescribing of that company's drug.
Improving the Implementation of Nursing Care Process in Mekelle Hospital

description: Background: Despite the important role Nursing Process plays for the betterment of the health care, its implementation status is far below expected, particularly in developing countries. Similarly, the baseline assessment in this study showed that the implementation of Nursing Care Process in Mekelle hospital is poor. Thus, in light of the national and regional efforts to improve health care delivery, it is critically important to improve the implementation of the Nursing Process in Mekelle Hospital. Objectives: To improve the implementation of Nursing Care Process from 37% to 60 in Medical and Surgical ward of Mekelle Hospital, by the end of September 2013 Methodology: A facility based pre- post interventional study was conducted from December to July, 2013 in Mekelle Hospital, Tigray Ethiopia. The interventions included training of ward nurses; strengthening internal supportive supervision and providing nursing process forms. A total of 97 Medical Records were reviewed (48 at baseline and 49 at the end of the study) to compare the Nursing Process implementation status pre and post-intervention periods. The proportion of patients with complete documentation of the Nursing Process forms and Chi – square test was calculated to test the difference in the outcome of interest between the pre – and post –intervention periods. Result: The percentage of patient cards with complete Nursing Care Process increased from 37.5% in baseline to 63.3% after intervention. This change was statistically significant at (df = 6.44, P =0.011). Similarly, the implementation of all components of the Nursing Process has increased: Nursing Admission Assessment (from 58.3% to 87.8,/ P =0.001), Nursing Diagnosis (from 66.7% to 93.9%, P =0.001); Nursing Care Plan (from 68.8% to 91.8% / P =0.004 ); Nursing Implementation (from 64.6% to 91.8% / P =0.001 ) and Nursing Evaluation (from 45.8% to 65.3% / P = 0.054), with all changes showing statistically significant at P < 0.05, except Nursing Evaluation. Conclusion and Recommendations: Continuous internal Supportive Supervision of Nurses followed by on job training continuous flow of related forms can improve the implementation of the Nursing Process. Mekelle hospital managers should consider strengthening the internal Supportive Supervision to improve the Nursing Process in their health facility.

Rotation and interaction of the September 8 and 10, 2014 CMEs tested with EUHFORIA

description: Solar coronal mass ejections (CMEs) can catch up and interact with preceding CMEs and solar wind structures to undergo rotation and deflection during their propagation. We aim to show how interactions undergone by a CME in the corona and heliosphere can play a significant role in altering its geoeffectiveness predicted at the time of its eruption. We consider a case study of two successive CMEs launched from the active region NOAA 12158 in early September 2014. The second CME was predicted to be extensively geoeffective based on the remote-sensing observations of the source region. However, in situ measurements at 1~au recorded only a short-lasting weak negative Bz component followed by a prolonged positive Bz component. The EUropean Heliosphere FORecasting Information Asset (EUHFORIA) is used to perform a self-consistent 3D MHD simulation of the two CMEs in the heliosphere. The initial conditions of the CMEs are determined by combining observational insights near the Sun, fine-tuned to match the in situ observations near 1~au, and additional numerical experiments of each individual CME. By introducing CME1 before CME2 in the EUHFORIA simulation, we modelled the negative Bz component in the sheath region ahead of CME2 whose formation can be attributed to the interaction between CME1 and CME2. To reproduce the positive Bz component in the magnetic ejecta of CME2, we had to initialise CME2 with an orientation determined at 0.1~au and consistent with the orientation interpreted at 1~au, instead of the orientation observed during its eruption. EUHFORIA simulations suggest the possibility of a significant rotation of CME2 in the low corona in order to explain the in situ observations at 1~au. Coherent magnetic field rotations, potentially geoeffective, can be formed in the sheath region as a result of CME-CME interactions in the heliosphere even if the individual CMEs are not geoeffective.

description: Suppose that $X,Y$ are positive random variable and $m$ a numerical (commutative) mean. We prove that the inequality ${\rm E} (m(X,Y)) \leq m({\rm E} (X), {\rm E} (Y))$ holds if and only if the mean is generated by a concave function. With due changes we also prove that the same inequality holds for all operator means in the Kubo-Ando setting. The case of the harmonic mean was proved by C.R. Rao and B.L.S. Prakasa Rao.

description: This paper discusses the charmonium and bottomonium correlators in the pseudoscalar channel and the corresponding spectral reconstruction on the lattice. The absence of a transport peak in the pseudoscalar channel spectral function allows for an easier study of the in-medium modification of bound states. However, extracting spectral information from Euclidean correlators is still a numerically ill-posed problem. To constrain the spectral reconstruction, we use an ansatz motivated from perturbation theory. The perturbative model spectral function has two main contributions: a thermal part around the threshold obtained from pNRQCD and the vacuum part well above the threshold. These two regions are matched continuously, and the model spectral function is obtained by introducing parameters that control the overall thermal shift of the peak and the overall amplitude. The lattice correlator data is computed using clover-improved Wilson valence fermions on large and fine gauge field configurations generated using $N_f=2+1$ flavors Highly Improved Staggered Quark (HISQ) action with physical strange quark mass $m_s$, and slightly heavy degenerate up and down quark masses $m_l=m_s/5$ that corresponds to $m_π\simeq 320$ MeV. Our results obtained at $T=220$ MeV and $T=251$ MeV suggest that no resonance peaks are needed to describe the charmonium lattice data at these temperatures, while for bottomonium thermally broadened resonance peaks persist.
