Reducing Broadband Shortwave Radiometer Calibration-Bias Caused by Longwave Irradiance in the Reference Direct Beam  [PDF]
Ibrahim Reda, Afshin Andreas, Mike Dooraghi, Manajit Sengupta, Aron Habte, Mark Kutchenreiter
Atmospheric and Climate Sciences (ACS) , 2017, DOI: 10.4236/acs.2017.71004
Abstract: Shortwave radiometers such as pyranometers, pyrheliometers, and photovoltaic cells are calibrated with traceability to consensus reference, maintained by Absolute Cavity Radiometers (ACRs). The ACR is an open cavity with no window that measures the extended broadband spectrum of the terrestrial direct solar beam irradiance, unlike shortwave radiometers that cover a limited range of the spectrum. The difference between the two spectral ranges may lead to calibration bias that can exceed 1%. This article describes a method to reduce the calibration bias resulting from using broadband ACRs to calibrate shortwave radiometers by using an ACR with Schott glass window to measure the reference broadband shortwave irradiance in the terrestrial direct solar beam from 0.3 μm to 3 μm. Reducing the calibration bias will result in lowering the historical solar irradiance by at least 0.9%. The published results in this article might raise the awareness of the calibration discrepancy to the users of such radiometers, and open a discussion within the solar and atmospheric science community to define their expectation from such radiometers to the radiometers’ manufacturers and calibration providers.
The practice of essential nutrition actions in healthcare deliveries of Shebedino District, South Ethiopia  [PDF]
Habte Bolka, Amanuel Alemu Abajobir
Advances in Reproductive Sciences (ARSci) , 2014, DOI: 10.4236/arsci.2014.21002
Abstract: The essential nutrition actions explain nutrition through life cycle approach addressing women’s nutrition during pregnancy and lactation, optimal infant and young children feeding, nutritional care for sick children and control of anemia, iodine and vitamin A deficiencies. Essential nutrition action has been implemented and resulted in positive outcome in less developed countries. However, the status of practice and associated factors were not studied in Ethiopia. Thus, institution-based cross-sectional study was conducted to assess the practice of essential nutrition actions in healthcare deliveries of Shebedino District, South Ethiopia. Quantitative data were collected though face-to-face interview with health workers and triangulated with data obtained through in-depth interview with health managers in the district and non-participatory observation of client-provider interaction in health facilities. Data were analyzed using SPSS16.0 software. Descriptive and logistic regression analyses were undertaken. The study revealed that 61 (56.0%) health workers practiced essential nutrition actions. Seventy one (65.1%) health workers were trained on essential nutrition actions. The practice of essential nutrition actions was associated with career structure of the health workers (AOR = 6.79, 95%CI: 2.31, 19.98), essential nutrition actions knowledge of health workers (AOR = 6.87, 95%CI: 2.11, 21.51) and availability of monthly nutrition related report form (AOR = 4.95, 95%CI: 1.46, 16.81). The practice of essential nutrition actions was low. The factors affecting the practice were inadequate training and knowledge of essential nutrition actions, career structure of the health workers and availability of monthly report form. Training should be provided for health workers on essential nutrition actions; moreover, essential nutrition actions indicators should be included in monthly report forms of the health institutions.
E-Learning in Engineering through Videoconferencing: The Case of the Addis Ababa Institute of Technology
Bedilu Habte
International Journal of Engineering Pedagogy , 2013, DOI: 10.3991/ijep.v3i2.2385
Abstract: In addition to their ability to reach distant learners, interactive e-learning environments have the potential to make the teaching-learning process more effective. This paper highlights some of the e-learning implementation efforts at the Addis Ababa Institute of Technology (AAiT) in Ethiopia. This case study shows that limited resources do not deter a developing nation to exploit the power of e-learning. Based on feedback from participants in the first national videoconferencing program held in Ethiopian higher education system between October 2011 and June 2012, the paper addresses the lessons learned and recommended actions for moving forward to a successful implementation of e-learning in Ethiopia, particularly in a videoconferencing mode.
Upper extremity deep vein thrombosis in a 25 years old apparently healthy man
Fitsum Habte
Pan African Medical Journal , 2010,
Abstract: This case of upper extremity deep vein thrombosis is selected for case report as it is a rare form of deep vein thrombosis without a very well established treatment modality and prognosis. The objective of this study was to report the outcome of a 25 years old male patient with idiopathic upper extremity deep vein thrombosis treated conservatively with low molecular weight heparin (LMWH) and oral warfarin. The data sources used were patient interview, laboratory and radiology investigation results and patient charts. The patient had no apparent recurrence or complication for 3 years except the presence of occasional dull pain over the affected left upper extremity
Runoff and Sediment Modeling Using SWAT in Gumera Catchment, Ethiopia  [PDF]
Kaleab Habte Michael Mamo, Manoj K. Jain
Open Journal of Modern Hydrology (OJMH) , 2013, DOI: 10.4236/ojmh.2013.34024
Abstract: This study was undertaken to examine the applicability of the SWAT model in Gumera river basin upstream of Lake Tana, Ethiopia for simulating stream runoff and sediment load. The area of river basin was discretized into 24 sub-catchments using ArcSWAT interface of the model. The semi automated Sequential Uncertainty Fitting (SUFI2) and fully automated Parameter Solution (ParaSol) calibration process built in SWAT calibration and uncertainty program (SWAT-CUP) were used to calibrate the model parameters using time series of flow and sediment load data of 1994 to 2002 and validated with the observed data from years 2003 to 2006. The performance of the model was evaluated using statistical and graphical methods to assess the capability of the model in simulating the runoff and sediment yield for the study area. The coefficient of determination (R2) and NSE values for the daily runoff by using [ParaSol] optimization technique was obtained as 0.72 and 0.71 respectively for the calibration period and 0.79 and 0.78 respectively for the validation period, R2 and NSE values of monthly flow calibration using SUFI2 are 0.83 and 0.78 respectively for validation it was 0.93 and 0.93. For monthly sediment yield by using SUFI2 calibration technique the model evaluation coefficients R2 and NS for calibration was computed as 0.61 and 0.60 respectively, for validation it was 0.84 and 0.83 respectively. The sensitivity analysis on 13 runoff producing parameters was also carried out and discussed.

Adult Infectious Disease Consultation over a 10-Year Period in a Community-Base Teaching Hospital  [PDF]
Eyassu Habte-Gabr
Open Access Library Journal (OALib Journal) , 2015, DOI: 10.4236/oalib.1102128
Abstract: This is a descriptive review of a large number (5606) of both in and outpatient adult infectious disease consultation from a major teaching hospital over extended period (2001-2010). The purpose of the study is to get spectrum of ID and determine trends in occurrence by age and sex. The common inpatients ID consultations were SSTIs, septicemia, osteomyelitis and that for outpatient by far most common were HIV/AIDS in over a third, followed by SSTI, osteomyelitis. There was equal distribution by sex and race (African-American and Caucasian), but consultations increased with age (33% in 60 and 32% in 45 - 59 year) especially septicemia and osteomyelitis. This data base shows spectrum of ID consultations (in and outpatient) over a long period has significance to teaching, performance for future possibly prospective studies and research priorities.
