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

No full textSome ultrastructural aspects on the Aeolosoma viride nervous system
No full textAccording to Bunnke (1967), the nervous system of the aelosomatid Aeolosoma consists of a brain, situated dorsally in the prostomium, a periesophageal girdle connecting the brain with the first suboesophageal ganglion, and a ventral nerve cord. We have observed ultrstructural aspects of the Aeolosoma viride nervous system.
All the parts of the nervous system are adjacent to the integument cells.
In the brain the neurons are found, mostly, dorso-laterally with respect to the nerve fibers (neuropil) and constitute most of the brain. Ultrastructurally, these neurons are diversified by the presence of granulated vesicles of various sizes, respectively 90-120 nanometers (type A) and 60-70 nanometers (type B). Furthermore, type-A neurons have a denser cytoplasm than that of electrons, rich in free ribosomes; conversely, those of type B have a less dense cytoplasm and a smaller number of free ribosomes. Both contain clear not granulated vesicles, of about 40-60 nm in diameter.
The nerve fibers of the neuropil have, mostly, a diameter of 0.1-0.5 m and a plasma membrane of about 9 nm and contain granulated vesicles corresponding to those present in the two types of neurons described.
Next to these thin fibers, the neuropil contains some thick fibers (0.5-2 m in diameter) and can be regarded as giant fibers (GF).
The GF do not have myelin-type sheaths and their plasma membrane (about 9 nm), is separated from that of the thin fibers by a space of about 20 nm.
The ganglions of the ventral nerve cord, also placed subepithelially, are formed by a peripheral crown of neurons (about ten) and a central area of fibers. The neurons are of type A and B (the latter slightly predominant) and do not have differentiated characteristics with respect to those described for the brain apart from some lisosomes and/or myelin figures. As for the fibers of the central area their direction is essentially oral-aboral. The GF are visible. The commissures are very reduced.
The nerve fibers of the connective tissues, which join ganglions of successive metameres, have a longitudinal direction and have the same type of fibers present in the brain and ventral ganglions.
Fibres were found also near the intestine.
The structure of the ventral nerve cord looks like that of the polychaetes in the surface position of the ganglions and those of the oligochaetes in the marked shortening of the commissures
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
Experimental investigation of the effects of chicken and turkey biodiesel blends on diesel engine noise emissions
No full textIn today's technology age, especially in urban areas, one of the most important sources of environmental noise pollution is diesel engines. Due to the limited availability of petroleum-based fuels, produced in only certain regions of the world maps, high cost, and being one of the most important causes of environmental pollution, in recent years, researchers have intensively focused on the study of alternative energy sources. Today, one of the most important alternative energy sources is biodiesel obtained from various natural sources. In this study, the effect of broiler chicken and turkey biodiesel on the noise emission of diesel engines was investigated experimentally. The biodiesels were produced with special methods using broiler chicken and turkey rendering fats. Two different kinds of biodiesels were homogeneously blended into the diesel fuel at proportions of 10%, 20%, and 50%. Engine tests were carried out at full load at various engine speeds and partial loads at a constant speed of 2000 rpm. During the experiments, noise measurements of the engine were taken by hand-held noise analyser. For more detailed assessment, 1/3 octave band noise analysis between 10 and 10 kHz was performed as well. Compared with diesel fuel, results of the noise analyses showed that use of biodiesel blends produced from broiler chicken and turkey rendering fat in diesel fuel has no significantly effect on engine noise emissions. Biodiesels produced from broiler chicken and turkey fats can be used safely in terms of noise emissions as engine fuels
Very ductile polymer concrete using carbon nanotubes
No full textReda Taha, Mahmoud M./0000-0002-3707-9336; Emiroglu, Mehmet/0000-0002-0214-4986WOS: 000456755400042Polymer concrete (PC) is a type of concrete where a polymer is used to replace cement as the binder. PC is an impermeable and chemical resistant concrete with appreciable mechanical properties. However, for most structural engineers, PC advantages do not outweigh its higher cost when compared with normal cement concrete. We report on the production of very ductile PC (measured by tensile strain at failure) with appreciable tensile strength utilizing a hybrid mixture of pristine and carboxyl (COOH) functionalized multi-walled carbon nanotubes (MWCNTs) at 2.0 wt% of epoxy resin. Experimental investigations reveal that COOH functionalization maximizes PC ductility reaching unprecedented 5.5% failure strains and increasing toughness by 184%. Fourier transformation infrared spectroscopy and dynamic modulus analysis indicate an increase in crosslinking density of the epoxy matrix up to 84% due to the carbonyl band formation induced by the COOH functionalization of MWCNTs. The significant improvement in ductility and energy absorption provides a promising platform for creating very ductile PC with attractive properties. (C) 2018 Elsevier Ltd.

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
