A separate air channel between ports 3 and 4 allows the application of a temporary vacuum at the PDMS interface to draw fluid from the main perfusion channel into the culture chambers. Ports 57 comprise the DAW dynamic stimulation generator. e chambers. Upon the application of a vacuum in the air channel at time 0, fluid containing cells is rapidly drawn into the culture chambers and fills the traps within 2 min, at which point the vacuum is turned off. </p>

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
Teaching of cartography in the 2. treee-year period of elementary school based on the example of students of the 4. and 5. grade of elementary school
No full textKartografsko opismenjevanje je dolg in zahteven učni proces, s katerim se učenci v manjši meri srečajo že v prvem triletju, bolj podrobno pa se z njim spoznajo v 4. in 5. razredu osnovne šole. Bistvo kartografskega opismenjevanja je posameznika usposobiti za uporabo kartografskih prikazov. Namen magistrskega dela je na osnovi načrtovanega in izvedenega pedagoškega eksperimenta ugotoviti, kako kartografsko opismenjeni so učenci 4. in 5. razreda izbrane osnovne šole in ali lahko s pomočjo dodatnega gradiva in terenskega dela izboljšamo njihovo kartografsko pismenost. Z analizo veljavnega Učnega načrta družba za 4. in 5. razred smo ugotavljali številčno zastopanost učnih ciljev, vezanih na kartografijo in njihovo vsebinsko ustreznost. Rezultati analize Učnega načrta družba so pokazali, da kartografski učni cilji za 4. in 5. razred skupaj predstavljajo le 12,5 % vseh operativnih ciljev. V praktičnem delu naloge sta bili uporabljeni metodi pedagoškega eksperimenta in kvalitativna metoda – intervju z učiteljico učencev, ki so bili vključeni v pedagoški eksperiment. V slednjega je bila vključena kombinirana učna skupina učencev, ki v šolskem letu 2019/20 obiskujejo 4. in 5. razred. Skupno je sodelovalo 10 učencev, štirje učenci 4. razreda in šest učencev 5. razreda. Rezultati praktičnega dela so pokazali, da so vsi učenci izboljšali svojo kartografsko pismenost. Ugotovili smo tudi, da je terensko delo bistveno pripomoglo k boljši kartografski pismenosti, kjer pa se je pokazalo tudi, da so se učenci bolje orientirali z ročnim kompasom v primerjavi z uporabo GPS-a na mobilnih napravah. Učiteljica, ki poučuje predmet družba v kombiniranem oddelku, meni, da so izdelano učno gradivo in učne priprave primerne za uporabo tudi v prihodnjeCartographic literacy is a long and complex learning process. The students are introduced to it already in the first three-year period to a lesser extent, but a more in-depth engagement follows in the 4th and 5th year of primary school. The essence of cartographic literacy is to train a person for the use of cartographic images. The purpose of this master’s thesis is to determine, based on a planned and executed pedagogical experiment, how much cartographic literacy do the students of the 4. and 5. year of primary school possess and is it possible to enhance their cartographic literacy with the help of some additional material and field work. With the analysis of the current syllabus for the 4th and 5th class of primary school we determined the number of learning goals connected with cartography and their content adequacy. The results of the analysis of the syllabus Society showed that the cartographic learning goals for the 4th and 5th class represent only 12,5 % of all operative goals. The practical part of the thesis included the method of a pedagogical experiment and a qualitative method – an interview with the teacher of the students included in the pedagogical experiment. The latter included a combined student learning group, which attended the 4th and 5th class in the year 2019/20. A total of 10 students were included in the experiment, four from the 4th class and six from the 5th class. The results of the practical part showed that all students improved their cartographic literacy. We also determined that the field work has significantly contributed to a better cartographic literacy, but it also showed that the students were able to orient themselves better with the help of a compass rather than a GPS app on their mobile phones. The teacher of the subject Society in a combined department believes that the set learning materials and learning preparations are adequate for future use
