Population Structure of Woody Plant Species at Jello-Muktar Dry Afromontane Forest, South-Eastern Ethiopia
No full textThere is limited quantitative information with regard to the vegetation structure in South-eastern Ethiopia. This study was therefore carried out to determine the density, DBH, Basal area and height distributions of woody plant species at Jello-Muktar dry afromontane forest. Systematic sampling design was used to collect vegetation data in total of 90 circular sample plots of each 30cm radius. In each plot all woody plants which are ≥2 cm diameter at breast height and height > 1m were identified, measured and recorded. Analysis of Size class distribution was performed for height (100 cm and above) and diameter classes (2 cm and above) and BA of each woody plant species with DBH ≥ 2 cm was computed The study revealed that more than 93% of the individuals had the DBH class distribution of more than 40.01 cm DBH. The DBH class distribution showed an inverted J-shape curve with the presence of more individuals in the lower DBH classes which is an indication of the active regeneration. The basal area in this study ranged from 10.9 m 2/ha for DBH class 1 to 59.02 m 2/ha for DBH class 11. The total basal area was found to be 245.65m2 and there was a J-shape curve relationship between DBH class and basal area class distribution. About 89 % of trees and shrubs had heights of more than 5m tall but only 3.45% the total individuals recorded were more than 30m. The population structure of the entire forest showed higher stem densities in the Lower diameter classes and progressively declining stem densities with increasing Diameter classes. Study of woody plant species population structure is an invaluable strategy for planning management actions and also helps in identifying the status of the forest stand with regard to its rate of disturbance. Hence it is better to manage those parts of forest stands with less number of individuals through enrichment planting of indigenous tree species.

Comparative study of woody species diversity, composition, structure and aboveground biomass carbon stock of Jello Muktar Dry Afromontane Forest with adjacent agroforestry, Southeastern Ethiopia
No full textReduction in plant species diversity, influences the potential of carbon stocks in a given land use. The forest are disappearing at an alarming rate in the tropics, so the role of agroforestry (AF) as a conservation tool and carbon sequestration needs to be further explored by comparing with forests. Thus, the aims of this study was to evaluate and compare woody species diversity, Composition, Structure and above ground biomass (AGB) carbon stock of Jello Muktar Dry Afromontane forest (JMF) and its adjacent AF. Dataset from forest inventory (n = 30), undertaken in JMF was used. For AF forty sample plots with 20 m × 20 m were sampled with stratified systematic sampling techniques. Woody species diversity analysis were carried out using Shannon Weiner Diversity index (H'), Simpson diversity (D) and Evenness index (J) whereas, similarity was carried out using Sørensen coefficient of similarity (Ss) index respectively. General and species or site specific allometric equations were used to calculate the AGB. A total of 74 woody species belonging to 47 families were recorded across the two land uses. The species similarity index between the two studied land uses was low (17.65%). The independent samples test indicated higher values of H' (3.20), D (0.95), and J (0.95) indices in JMF compared to the adjacent AF values of H' (2.09), D (0.83), and J (0.80). However, no statistically significant difference (p < 0.05) was observed for the H' index between JMF and AF. AGB carbon stock was significantly (p<0.05) higher in JMF than and its adjacent AF. There was a positive relationship between diversity and carbon stock in the two studied land uses. The study revealed that preserving forests for both biodiversity and climate change mitigation is vital along with the complementary role AF to buffer the forest

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied

Intern experience at CH���M Hill, Inc.: an internship report
No full textIncludes author's vita"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesA review of the author's internship experience with CH���M HILL, Inc.
during the period September 1975 through May 1976 is presented. During this nine month
internship the author worked as an Engineer II in the Industrial Processes discipline of this
large consulting engineering firm... The author's prime responsibility was as one of three
lead design engineers on the design of a large wastewater treatment facility for a pulp mill
in Hoquiam, Washington owned by ITT Rayonier Inc. The work generally consisted of the design
of individual treatment units and associated piping and pumping. The purpose of the project
was to provide wastewater treatment capabilities that would satisfy the effluent limitations
(standards) imposed upon the mill by the State of Washington Department of Ecology and the
U.S. Environmental Protection Agency. The author's assignment also entailed necessary
interaction with the project manager and other CH���M HILL design engineers and support staff
members, the client's representatives, and representatives of two other consulting engineering
firms working on the project. Thus, the internship position at CH���M HILL provided considerable
experience coordinating the author's work with the work of other engineers, guiding the design
and administrative efforts of a support staff, and interacting regularly with the client and
other consulting firms. This broad exposure to a variety of engineering and organizational
problems provided a valuable educational experience
