Determinación de la Cinética de Extracción de Aceite de la Semilla de Nim empleando Hexano como Solvente, por Método Discontinuo
Creators: name: Espinosa Morales, Rodolfo
Publisher: name: Universidad Nacional de Ingeniería (UNI)
Year: 1993

description: El presente trabajo está dirigido al estudio de la influencia de algunas variables de operación sobre la cinética de la extracción de aceite de la semilla de nim, y a la selección de los valores más adecuados de esas variables. Las evaluaciones se realizaron por el método discontinuo empleando hexano comercial como solvente. Se realizó una revisión bibliográfica para seleccionar un método de laboratorio y condiciones similares a las existentes en una planta piloto en la cual se planea continuar los estudios. También se hizo una revisión bibliográfica acerca de los factores que influyen en la cinética de la extracción, y las leyes que la rigen con el fin de seleccionar la expresión más simplificada para la construcción de las curvas de velocidad de extracción. Dado que la mayoría de los parámetros han sido establecidos durante el tratamiento previo de la semilla, se han considerado como variables la temperatura de extracción y la relación másica solvente - sólido. Se observa el cambio de concentración del aceite en el extracto respecto al tiempo. Se realizó una comparación cualitativa de los resultados experimentales y las curvas cinéticas construidas con estos. Además, se hace un análisis de su comportamiento frente a lo indicado en la teoría. Se comprobó que la velocidad de extracción y la cantidad de soluto que difunde fuera del sólido son apreciablemente mayores a la mayor temperatura, a la cual la variación de la relación másica no presenta influencias significativas. Se propone como condiciones más adecuadas de trabajo la temperatura de ebullición del solvente y la relación másica mínima investigada. A estas condiciones se espera que en 3 horas casi el 100% del soluto haya difundido hacia el extracto.

description: Background: Sexual violence is a serious public health and human rights problem with both short-and long-term consequence on women's physical, mental, sexual and reproductive health. Objective: To assess the prevalence and determinants related to sexual violence among house maids of Addis Ababa, Ethiopia Methods: School based cross sectional study design was conducted among female housemaid students from January 27-march7, 2015 in Addis Ababa, Ethiopia. A total of 473 sample sizes were considered. Multistage sampling techniques were employed. Data was collected using closed ended and open ended self-administered questionnaire. Five percent of the questionnaire was pretested. Data was entered through Epi-data version 3.1 and was analyzed through SPSS version 20. Measurements of central tendency like mean were presented. Odds Ratio and 95% Confidence Interval was calculated for each independent variable against the dependent variables. Result: A total of 451 housemaid's had participated with a response rate of 95.3%. The study has indicated that the prevalence of sexual violence was 28.6%.Housemaid monthly income <300birr were three times [AOR=3.112(1.484, 6.523)] more likely to be sexually violated than those whose monthly income is >450birr. Housemaids whose employer drunk alcohol were 14 times [AOR=14.53(7.62, 27.703)] more likely to be sexually violated compared to those housemaids whose employer do not drink alcohol. Conclusion and Recommendation Sexual violence among housemaids is rampant. Low income of the housemaid and alcohol drinking by perpetrator was found to be a risk for sexual violence. Empowering housemaids to develop self-confidence through education, and improving their ability to find employment and income, along with increasing public awareness of human rights issues is vital.

Economic Analysis and Design for the Selection of Two Units of Single Cell and One Unit of Double Cell Pre-stressed Box girder Railway Bridges
Creators: name: Misiker, Jemberu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Currently, railway transport system is being the most efficient, environmentally friendly, space-saving means of land transport system. Due to the new technologies and innovations made to such way of transporting goods and passengers, a lot of studies and documentations are being politicized. Among the new technologies added to this transport system is segmental bridge construction where simple span railway bridges are placed over two successive piers. As such long distances of railway bridges are being constructed by assembling simple span pre-fabricated segmental girders placed on the piers. One of the ways to prefabricate girders before on site erection on the piers is to pre-stress the structural member and modify its material properties (i.e. a reduced weight of concrete, reaching the full strength of the concrete and steel). In this research, an attempt is made to economically compare analysis and design of two units of single cell pre-stressed box girders and one unit of double cell pre-stressed box girder railway bridges and to select an economical one on the basis of construction material cost. For both cases, cost versus span is made so as to meet the economic comparison objectives of the study. Bases on the study, it is obtained that applying two units of single cell pre-stressed box girder railway bridges is uneconomical way of arrangement than one unit of double cell pre-stressed box girder railway bridge for simple spans greater than 34m.
ARCHAEOLOGICAL INVESTIGATIONS OF SITE 36LU312, CANAL STREET, LATTIMER LUZERNE COUNTY, PENNSYLVANIA

description: The University of Maryland Anthracite Heritage Program summer archaeological field methods course (ANTH496) was taught in Lattimer, Luzerne County, Pennsylvania (previously Lattimer Village No.1). From May 29th to July 6th of 2012, the previously undocumented Canal Street site (36LU312) was investigated. The following report outlines the Phase I and II archaeological investigations at the Canal Street Site. All archaeological review, curation, and writing were completed in accordance with The Pennsylvania State Historic Preservation Office, Pennsylvania Historical and Museum Commissions Guidelines for Archaeological Investigations in Pennsylvania as amended. Site 36LU312 consisted of coal company-constructed houses. From as early as 1878, up to nine structures of varying sizes and shapes lined the Canal Street road, and over the course of the following seven decades, the structures in this area changed size and shape as additional outbuildings, we added and subtracted to meet the needs of their occupants. The Canal Street section of Lattimer No.1 consisted of an ethnic enclave of primary Slavic and Italian immigrants; this ethnic diversity in the northeast area of town provides a unique perspective in an otherwise ethnically segregated company town. The objective of this work was to assess the integrity of archaeological deposits at the sites to aid in research themes related to the lives of 19th- and 20th-century immigrants and an examination of ethnic enclaves in patch-towns. These research themes include land usage, access to commodities, household demographics, and structural violence. The field school investigations included historical research and excavation of shovel test pits and test units of varying sizes. In total, 32 shovel test pits (STPs) and 13 test units were excavated. The site yielded 9,992 artifacts, 6% of which were ceramics, 35% of which were glass, and 49% of which were metal. A minimum of 76 ceramic and glass vessels were identified. Analysis of the Canal Street artifact assemblage is guided by research themes to provide a coherent framework of understanding the occupation and lifestyle of household residents. The research themes include: (1) a spatial analysis of land usage, (2) an analysis of residents' access to commodities and the effects of such access, (3) an analysis of household and neighborhood demographics, (4) and a discussion about structural violence. The large portion of the material culture recovered from these investigations consisted of modern materials or non-diagnostic materials. The diagnostic materials recovered from the Canal Street assemblage provide a framework that can be used as a model in the analysis of ethnical diverse company towns.

description: The paper has made a study on the practices and challenges of logistics in Ethiopian plastic recycling companies with regard to customer service, inventory management, supply, transportation and warehousing activities. The main objective of the study was to describe the current logistics practices. Descriptive research type was used, and quantitative and qualitative data was collected related with the extent of companies' logistics practices using structured questionnaires and different secondary documents. Since the total population is small in number, the target population covers all the seventeen Plastic recycling companies and from logistics perspective, 3 respondents selected by using expert purposive sampling who work in main logistics activity of Purchasing, Production & Marketing and have glean knowledge in particular expertise in logistics activity. Questionnaires distributed to 48 respondents but filled and returned only from 42. Finally, the collected data was analysed using descriptive statistics, and secondary document analysis is done for confirming the findings. The result indicates almost all the modern logistics infrastructures like ERP, EDI and Radio frequency are not applied by these firms for ease of logistics operation, and commonly logistics is practiced at the lesser extent. Even though these firms practiced the logistics activities in their day to day operations, most of the firms have no logistics department in their organizational structure. Foreign currency shortages, higher taxes, lack of integrated system and long lead time in ports are found to be the critical challenges of logistics for plastic recycling companies in Ethiopia. It is recommended that, the companies can measure their logistics performance by applying different metrics like financial, productivity, quality and cycle time that help to know the gaps easily and to take corrective actions.

description: We investigate two-dimensional liquid bridges trapped between pairs of identical horizontal cylinders. The cylinders support forces due to surface tension and hydrostatic pressure which balance the weight of the liquid. The shape of the liquid bridge is determined by analytically solving the nonlinear Laplace-Young equation. Parameters that maximize the trapping capacity (defined as the cross-sectional area of the liquid bridge) are then determined. The results show that these parameters can be approximated with simple relationships when the radius of the cylinders is small compared to the capillary length. For such small cylinders, liquid bridges with the largest cross sectional area occur when the centre-to-centre distance between the cylinders is approximately twice the capillary length. The maximum trapping capacity for a pair of cylinders at a given separation is linearly related to the separation when it is small compared to the capillary length. The meniscus slope angle of the largest liquid bridge produced in this regime is also a linear function of the separation. We additionally derive approximate solutions for the profile of a liquid bridge making use of the linearized Laplace-Young equation. These solutions analytically verify the above relationships obtained for the maximization of the trapping capacity.

The Impact of Foreign Direct Investment on Poverty Reduction in Ethiopia: Co-integrated Var Approach
Creators: name: Kedir, Remla
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: Many developing countries are competing to attract foreign direct investment with a belief that it can be a tool for poverty reduction. The Ethiopian government has opened several economic sectors to foreign investors and issued several investment incentives for foreign investors. Since the market oriented economic reforms took place in 1992 emphasis has been given to attracting FDI. In this study, the relationship between FDI and poverty reduction is analyzed empirically. It is based on secondary data which was collected from the Ethiopian investment agency, UNCTADs database and the World Bank's world development indicators. The period covered in the study is 1970-2009. The model was estimated using the Co-integrated VAR approach. The results show that FDI has a negative, impact on economic growth and hence does not reduce poverty in the country. This may be due to the under development of human capital, backward institutions, crowding out of domestic investment or other reasons which require further investigation. The fact that FDI does not contribute to poverty reduction has an important implication for policy makers, especially trade and FDI policies must be checked closely in order to make FDI growth enhancing in Ethiopia
Transitioning youth with disabilities into society postsecondary: supports and implications

description: Triennial data collected by districts and reported by states identify students with emotional and behavioral disorders (EBD) as the subset of students with disabilities (SWD) most negatively affected by the transition from high school to postsecondary school or employment. Unfortunately, the quantitative data collected by the state does not provide sufficient information to understand the experiences of youth with EBD or for districts to improve transition outcomes. Specifically, the data reported does not inform the instructional content at the district level. In this mixed methods study, I analyzed disaggregated state-level data and explored the perceptions of youth with EBD in relation to their transition-specific instruction and outcomes to answer the following research questions: (1) How do the post-school outcomes for all SWD at West High compare to the post-school outcomes available for New Jersey?; (2) How do the post-school outcomes for students with EBD at West High compare to the post-school outcomes for the larger NJ population of students with EBD?; (3) What was the experience of students with EBD in the Disability Awareness and Transition (DAT) program post- graduation?; and (4) What do DAT students describe as influencing factors in their postsecondary outcomes? I interviewed eight high school graduates to explore their lived experiences postsecondary. More specifically, I explored how their time in one district’s disability awareness and transition program informed these experiences. Six themes emerged explaining their experiences and four in relation to their recommendations. The experiences of the participants were like a Roller Coaster Ride (Theme 1) beginning with the Disconnect (Theme 2) between understanding the need for applying what was taught in high school in postsecondary environments. Students described the impact of new Social Experiences (Theme 3) and the transition from supported decision making to intended independent decision making (Theme 4), emerging self-awareness (Theme 5), and self-determination (Theme 6) with many ups and downs. Themes emerged indicating that participants experienced support in small (Theme 7) community college/home environments and that they relied on support systems (Theme 8) and disabilities services to calm their ride (Theme 9). It is within all of these experiences that the participants identified age and lived experiences (Theme 10) as one of the most important influencing factors. Results inform disability awareness and transition instruction, recommendations for program improvement, and means of improving outcomes.

description: Background: Nurse Managers are nurses in management level positions in hospitals such as matron, head nurse as well as coordinators. Effective nursing management and leadership are essential for the provision of desired patient care that will contribute to the improvement of any country's health indicators. Objective: To assess managerial decision making involvement and associated factors by nurse managers at selected public hospitals, Tigray, north Ethiopia, in 2015. Methods: Institution based cross sectional study design was used. Sample size was 113 and selected using simple random sampling technique. Odds Ratio and 95% Confidence interval were calculated. A binary logistic regression with its statistical significance and multivariate analysis was employed. Result: Of the total respondents majority, 71(68.9%) of them didn't involve in managerial decision making. Those nurse mangers who were working in surgical ward 15.74 were more times likely to be involved in managerial decision making than those working in medical ward:[AOR =15.74 (95%CI: 1.32-186.99)]. Those nurse mangers who were working in ICU 86.6 times were more likely to be involved in managerial decision making than those working in medical ward :[AOR =86.6 (95%CI: 2.71 -2764.78)]. Matrons were 18.61 times more likely to be involved in managerial decision making than head nurse: [AOR= 18.61 (95CI%:1.03-335.41)] The odds of involvement of decision making among the respondents who had poor knowledge and skill were 2.56 lower than the odds of the respondents who hadn't poor knowledge and skill towards decision making: [AOR = 0.39( 95% CI (0.14-0.78)] Conclusion and recommendation Majority respondents were not involved in managerial decision making. Efforts of MOH, RHB, and administrators of the hospitals may be needed to improve managerial decision making of nurse managers and use their power regularly Key words: nurse manager, decision making, power, public hospital
Atmospheric constituents and surface-level UVB: implications for a paleoaltimetry proxy and attempts to reconstruct UV exposure during volcanic episodes

description: Chemical and morphological features of spores and pollens have been linked to changes in solar ultraviolet radiation (specifically UVB, 280-315 nm) at Earth's surface. Variation in UVB exposure as inferred from these features has been suggested as a proxy for paleoaltitude. While UVB irradiance does increase with altitude above sea level, a number of other factors affect the irradiance at any given place and time. In this modeling study we use the TUV atmospheric radiative transfer model to investigate dependence of surface-level UVB irradiance and relative biological impact on a number of constituents in Earth's atmosphere that are variable over long and short time periods. We consider changes in O3 column density, and SO2 and sulfate aerosols due to periods of volcanic activity, including that associated with the formation of the Siberian Traps. We find that UVB irradiance may be highly variable under volcanic conditions and variations in several of these atmospheric constituents can easily mimic or overwhelm changes in UVB irradiance due to changes in altitude. On the other hand, we find that relative change with altitude is not very sensitive to different sets of atmospheric conditions. Any paleoaltitude proxy based on UVB exposure requires confidence that the samples under comparison were located at roughly the same latitude, under very similar O3 and SO2 columns, with similar atmospheric aerosol conditions. In general, accurate estimates of the surface-level UVB exposure at any time and location require detailed radiative transfer modeling taking into account a number of atmospheric factors; this result is important for paleoaltitude proxies as well as attempts to reconstruct the UV environment through geologic time and to tie extinctions, such as the end-Permian mass extinction, to UVB irradiance changes.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: The paper examines whether a long-run relationship between financial development and economic growth exist in Ethiopia. It employs Co-integrated Vector Autoregressive (CVAR) approach to asses how the financial sector contributes to growth. It further used the granger causality test so as to find the direction of causality between financial development and economic growth. Impulse response and variance decomposition tests are also applied so as to see the interaction between financial development and economic growth. The study utilized time-series data of Ethiopia over the period 1980-2010. The findings support the existence of a uni-directional causality from economic growth to financial development. The emperical evidence, in addition, shows the presence of positive and significant long-run relationship between financial development and economic growth and an insignificant effect in the short-run. The results of Impulse response and variance decompositions also indicate the permanent effect of financial development on economic growth. The policy implication is that long-run policies of financial development are believed to provide significant effect on economic growth.

description: We present results of an investigation into the formation of nitrogen-bearing molecules in the atmosphere of Titan. We extend a previous model (Li et al. 2015, 2016) to cover the region below the tropopause, so the new model treats the atmosphere from Titan's surface to an altitude of 1500 km. We consider the effects of condensation and sublimation using a continuous, numerically stable method. This is coupled with parameterized treatments of the sedimentation of the aerosols and their condensates, and the formation of haze particles. These processes affect the abundances of heavier species such as the nitrogen-bearing molecules, but have less effect on the abundances of lighter molecules. Removal of molecules to form aerosols also plays a role in determining the mixing ratios, in particular of HNC, HC3N and HCN. We find good agreement with the recently detected mixing ratios of C2H5CN, with condensation playing an important role in determining the abundance of this molecule below 500 km. Of particular interest is the chemistry of acrylonitrile (C2H3CN) which has been suggested by Stevenson et al. (2015) as a molecule that could form biological membranes in an oxygen-deficient environment. With the inclusion of haze formation we find good agreement of our model predictions of acrylonitrile with the available observations.

Investigation on LTE for Advanced Real Time Two Way Communication for Railway Operational Excellence: Case of Addis Ababa – Djibouti Line
Creators: name: Farah, Mourad
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Railway communication network constitute an important element of the railway environment. It plays a crucial role in railway's operation effectiveness, capacity, safety and passenger experience. The actual communication system for the Addis Ababa-Djibouti railway line provides basic train operation and protection. However in the long term stage (2035), due to the increase of expected cargo and passenger traffic, it may become an obstacle. Hence the communication system would need an upgrade and alternative mobile technologies are considered to replace it. In this research work, GSM-R technology, which is state-of-the-art railway mobile communication technology, is investigated and its main shortcomings are exposed, namely: lack of capacity, limited data transmission capabilities, inefciency in radio resource usage and risk of obsolescence. Due to these signicant drawbacks, the Long Term Evolution (LTE) mobile technology is selected. This thesis is focused on designing LTE radio coverage network for the Ababa-Djibouti route. LTE relevant features and capacity is analyzed. A set of critical and non-critical applications, which enhance railway operation in terms of capacity, safety as well as passenger comfort, are proposed for the line. LTE radio network design parameters and appropriate algorithms are well selected. The link budget calculation is done by selecting a suitable path loss model. Radio coverage is based on an extensive work on the geographical and morphological nature of Addis Ababa-Djibouti route. Atoll software is used for simulation so as to optimize the network. Results of the simulation show that the whole line is well covered in terms of signal strength. Also the required total data rate capacity to be able to support the proposed applications is achieved. All in all, this thesis has tried to design LTE radio coverage network specific to the railway environment since LTE technology has only been designed for commercial purposes. Moreover it presents a feasible evolution in the eld of railway communications

The Banks-Zaks (BZ) expansion in a0=(8/321)(16.5-nf) is straightforward to obtain from perturbative results in MSbar or any renormalization scheme (RS) whose nf dependence is `regular.' However, `irregular' RS's are perfectly permissible and should ultimately lead to the same BZ results. We show here that the `optimal' RS determined by the Principle of Minimal Sensitivity does yield the same BZ-expansion results when all orders of perturbation theory are taken into account. The BZ limit provides an arena for exploring optimized perturbation theory at arbitrarily high orders. These explorations are facilitated by a `master equation' expressing the optimization conditions in the fixed-point limit. We find an intriguing strong/weak coupling duality a -> a*^2/a about the fixed point a*.

description: The Ehrhart polynomial of a lattice polygon P is completely determined by the pair (b(P),i(P)) where b(P) equals the number of lattice points on the boundary and i(P) equals the number of interior lattice points. All possible pairs (b(P),i(P)) are completely described by a theorem due to Scott. In this note, we describe the shape of the set of pairs (b(T),i(T)) for lattice triangles T by finding infinitely many new Scott-type inequalities.

description: Most street gang members use Twitter to intimidate others, to present outrageous images and statements to the world, and to share recent illegal activities. Their tweets may thus be useful to law enforcement agencies to discover clues about recent crimes or to anticipate ones that may occur. Finding these posts, however, requires a method to discover gang member Twitter profiles. This is a challenging task since gang members represent a very small population of the 320 million Twitter users. This paper studies the problem of automatically finding gang members on Twitter. It outlines a process to curate one of the largest sets of verifiable gang member profiles that have ever been studied. A review of these profiles establishes differences in the language, images, YouTube links, and emojis gang members use compared to the rest of the Twitter population. Features from this review are used to train a series of supervised classifiers. Our classifier achieves a promising F1 score with a low false positive rate.

Thermal Infrared Sky Background for a High-Arctic Mountain Observatory

description: Nighttime zenith sky spectral brightness in the 3.3 to 20 micron wavelength region is reported for an observatory site nearby Eureka, on Ellesmere Island in the Canadian High Arctic. Measurements derive from an automated Fourier-transform spectrograph which operated continuously there over three consecutive winters. During that time the median through the most transparent portion of the Q window was 460 Jy/square-arcsec, falling below 32 Jy/square-arcsec in N band, and to sub-Jansky levels by M and shortwards; reaching only 36 mJy/square-arcsec within L. Nearly six decades of twice-daily balloonsonde launches from Eureka, together with contemporaneous meteorological data plus a simple model allows characterization of background stability and extrapolation into K band. This suggests the study location has dark skies across the whole thermal infrared spectrum, typically sub-200 micro-Jy/square-arcsec at 2.4 microns. That background is comparable to South Pole, and more than an order of magnitude less than estimates for the best temperate astronomical sites, all at much higher elevation. Considerations relevant to future facilities, including for polar transient surveys, are discussed.

Rokhlin dimension for flows

description: We introduce a notion of Rokhlin dimension for one parameter automorphism groups of C*-algebras. This generalizes Kishimoto's Rokhlin property for flows, and is analogous to the notion of Rokhlin dimension for actions of the integers and other discrete groups introduced by the authors and Zacharias in previous papers. We show that finite nuclear dimension and absorption of a strongly self-absorbing C*-algebra are preserved under forming crossed products by flows with finite Rokhlin dimension, and that these crossed products are stable. Furthermore, we show that a flow on a commutative C*-algebra arising from a free topological flow has finite Rokhlin dimension, whenever the spectrum is a locally compact metrizable space with finite covering dimension. For flows that are both free and minimal, this has strong consequences for the associated crossed product C*-algebras: Those containing a non-zero projection are classified by the Elliott invariant (for compact manifolds this consists of topological K-theory together with the space of invariant probability measures and a natural pairing given by the Ruelle-Sullivan map).

Thermal Comfort for Passenger Train from Addis Ababa to Dire Dawa
Creators: name: Dawit, Getachew
Publisher: name: National Academic Digital Repository of Ethiopia

description: Air conditioning in passenger train is an effort to obtain controlled environmental conditions in accordance with the needs of passenger comfort and the passenger does not feel cold or hot. However, passengers will feel comfortable during the trip despite travel long distances and ravel times. Thermal comfort for the passengers inside the carriage is influenced by external and internal loads. The thermal environment when the passenger train travel from Dire dawa to Addis Ababa is hot that affect the driver's and passengers' health, performance and comfort. Due to spatial and temporal variation of state variables and boundary conditions in the vehicle cab, the heating, ventilating and air-conditioning (HVAC) does not have to be designed to provide a uniform environment, especially because of individual differences regarding to physiological and psychological. The objective of this paper focused on the design of a passenger railway air conditioning system through the route of Addis Ababa to Dire Dawa using Hourly Analysis program (HAP) software for estimating the thermal loads analysis and system design ,and Analytical method to estimate a thermal load only. Finally, the total cooling load using both methods HAP and Analytical methods 49.9kw and 48.74kw respectively, we designed the vehicle HVAC system and select the suitable Roof mounted package unit(RMPU) . Based on the design, conditioned the passenger compartment temperature at 23.5 o C with a humidity of 50% during winter or summer can feel comfortable. When the air condition inside the car less than 23 C with RH 60% felt uncomfortable.
