Evaluation of the Effectiveness of Avian Influenza Vaccines in Native Chicken Using Two by Two Contingency Table
Abstract. The aim of this study was to evaluate the effectiveness of vaccination program analysis method using the 2 x 2 contingency table to provide better assessment to the vaccination program management and implementation. This study used survey methods. A total of 230 serum samples from vaccinated chickens and 20 serum samples from unvaccinated chickens were used. The blood serum samples were then examined with the Hemagglutination Inhibition Test/HI to measure antibody levels. The data were analyzed using a 2 x 2 contingency table. Results showed that the level of vaccine protection was 68.92% with 31.31% vaccines failure rate, the level of natural protective immunity in samples was 0%, 100% vaccines specificity and the effectiveness of the vaccine was 71.20%. Keywords: Vaccination, contingency table, hemaglutination inhibition.

Dispelling the Myths Behind First-author Citation Counts
We 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
Following 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
Includes 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
In Vitro and in vivo Test of Exctract of Morinda citrifolia and Allium sativum on Subclinical Mastistis Cows
Two subsequent experiments were conducted in the current study. Experiment I (in vitro), milk obtained from sub-clinical mastitis dairy cows were used to identify the content of bacteria types causing mastitis. It was identified that the milk contained Staphylococcus sp (76.92%), Streptococcus sp (15.38%) and E. coli (7.69%). In order to determine the optimum combination of Morinda citrifolia (M) and Allium sativum (A) for reducing the number of the identified bacteria. The milk were randomly assigned to one of four treatments with six replicates in each treatment (Completely Randomized Designed). There were four treatments, which were four kinds of Morinda citrifolia (M) to Allium sativum (A) ratio, i.e. T1 (80:20); T2 (60:40); T3 (40:60); and T4 (20:40). Collected data were analysed using analysis of variance. When analysis of variance indicated significant effects, Least significant different (LSD) was then employed. It is indicated that T1 was the most optimum treatment to reduce bacteria counts. Experiment II (in vivo), the purpose of the experiment was to detemine the optimum dose of T1 to cure sub-clinical mastitis dairy cows and to investigate the effects of different doses of T1 on milk quality. A total of 20 sub-clinical mastitis dairy cows were randomly treated with one of five treatments for 3 days, which were C (received penicillin), P1 (received T1:100 ml/d); P2 (received T1:200 ml/d); P3 (received T1:300 ml/d) and P4 (received T1:400 ml/d). Analysis for variance was applied followed by dunnet’s test. Milk production and somatic cell counts were not significantly (P>0.05) affected by the treatments, but they significantly (P<0.005) influenced milk dry matter content. Dairy cows treated with P4 produced milk with the highest dry matter content (11.92 ± 1.90%). In conclusion, The mixtures of Morinda citrifolia and Allium sativum can cure mastitis and improve milk dry matter content.

Transition to turbulence in a qblique shock-wave/boundary-layer interaction at M=15
Direct numerical simulations are carried out for different forcing techniques to trigger transition during the interaction between an oblique shock-wave and a laminar boundary-layer at M = 1.5. Three forcing methods are used: a) forcing of oblique unstable modes, whose shape and behaviour are determined by the local linear stability theory, b) broadband free-stream acoustic disturbances, and c) a cold plasma flow control device. While the oblique-mode breakdown is dominant for low-amplitude forcing, long streaky structures drive the transition process in a high-amplitude disturbance environment. LES are also performed on the experimental setup by the Institute of Theoretical and Applied Mechanics (ITAM) from Novosibirsk State University with cold plasma actuation. As well as the disturbance type, the effect of Reynolds number and forcing amplitude will be investigated
