17925. Production And Quality Evaluation Of Spray Dried Fruit Products
Fruits and fruit products are the enigma of food in modern society. Fresh fruits are perishablernand have limited shelf life. To prolong shelf life, various processing and preservation methodsrnsuch as drying, chemical treatments and various packaging methods are used. Spray drying ofrnmango and...
17926. Synthesis Of Anionic Surfactant From Jatropha Oil
Due to the high cost of surfactant production caused by petrochemical feedrnstocks, considerable attention has been given to non-edible vegetable oils as anrnalternative source of feedstock. In this paper, a new non-edible oil derivedrnsurfactant based on Jatropha plant is synthesized. In this...
17927. Simulation Of Municipal Solid Waste Gasification In Updraft Fixed Bed Reactors
A steady state simulation of syngas production from municipal solid waste gasification process using fixed bed gasification technology was performed using Aspen Plus. For the simulation, the average proximate and ultimate compositions of municipal solid waste obtained from the koshe open dump site...

The discharge of tannery effluents to different water bodies increase pollution because of heavyrnaccumulation of toxic compounds such as sulfur and nitrogen containing organic wastes, chromium,rnarsenic etc. Thitty-six strains of Sulfur Oxidizing Bacteria (SOB) belonging to sixteen genera...
17932. Study On Macroinvbertebrates Abundance And Community Structure Of Lake Kuriftu Ethiopia
The aim of the study was to investigate the abundance, diversity and community structurernof macrobenthos in relation to some environmental variables. Benthic macroinvertebratesrnof Lake Kuriftu were sampled on a monthly basis from September 2009 to February 2010.rnEkman grab (0.0225m2) samples...
17933. Interior And Exterior Penalty Methods To Solve Nonlinear Optimization Problems
The methods that we describe presently, attempt to approximate a constrained optimiza-rntion problem with an unconstrained one and then apply standard search techniques suchrnas exterior penalty function method and interior penalty method to obtain solutions. Thernapproximation is accomplished in...
17934. Species Diversity And Abundance Of Birds Of Addis Ababa Bole International Airport
Ecological investigation of species diversity and abundance of birds was conducted fromrnAugust 2010 to March 2011 in Addis Ababa Bole International Airport. Transect count andrnpoint count methods were used to investigate the abundance of birds. Observation wasrnconducted by periodically walking...
17935. Nonlinear Transportation Problems
Some times there may be many di®erent ways to model a particular problem,rnchoosing the best one minimizes the complexity of the problem and time to solve.rnSince, as we have said earlier, any programming problem with constraint matrixrnstructure the same as the transportation problem is...
17936. Virological And Immunological Features Of Human Immunodeficiency Virus Type-l (hiv-l) Pre And Post Treatment Of Tuberculosis In Coinfected Patients
The association between HIVand Tuberculosis (I'B) is complex and bi- directional. Recentrnstudies demonstrated that TB accelerates the course of AIDS. In the present study lI'ernsought for virological and immunological features of HIV in TB co-ilifected individuals.rnThe study subjects are selected...
17937. Integration And Convergence Theorem
The purpose of this study is an attempt to explore sufficient condition for the convergence of Riemann integrable functions on any positive linear functional. The Arzela dominated convergence theorem holds for the Riemann integral provided it is assumed that the limit function is Riemann...
17938. Ear Infections Etiologic Agents Isolated From Patients Visiting Two Hospitals In Addis Ababa And Their Susceptibilities To Antimicrobials
Infonnation pertaining to the etiologic agents responsible for ear infection are absent inrnEthiopia. Therefore, this study was initiated to identify the causative agents together withrntheir sensitivities to antimicrobials. Microbiological samples were collected from 389 earsrnof 355 patients...
