Journal Article Problems

PUJ-1 After reading the article Designing gas-sparged vessels for mass transfer [Chem.Eng., 89(24), p. 61 (1982)], design a gas-sparged vessel to saturate 0.6 mVs of water up to an oxygen content of 4 X 10 Itg/m at 20°C. A liquid holding time of 80 s is required.

A number of books and journal articles reviewing computational methods relevant to biophysical problems have been published in the last decade. Two of the most popular texts, however, were published more than ten years ago those of McCammon and Harvey in 1987 and Brooks, Karplus, and Pettitt in 1988. There has been significant progress in theoretical and computational methodologies since the publication of these books. Therefore, we feel that there is a need for an updated, comprehensive text including the most recent developments and applications in the field.

Moves 2 and 3 of the conference abstract also parallel the moves of the journal article Introduction. Move 2 points out a gap in the field (e.g., a problem that needs to be solved, work that needs to be done) and serves as a transition to move 3, which describes the work to be presented. Depending on the goals of the project, different aspects of the work may be highlighted. In some instances, methods will be emphasized in others, results will be the focus of attention. When possible and appropriate, numerical data should be included in the conference abstract. If this is not possible, because you are still completing parts of the work, at least state in the abstract what data will be presented at the conference (e.g., Arsenic levels from two different lakes will be reported. ). Results are the... 

Proposals score high points if they present a creative approach or an innovative idea. A good idea that has already been explored, by you or by others, is seldom funded. A winning proposal must demonstrate that the proposed work will accomplish something new. Gap statements and gap-fillers, as in journal articles (see chapter 6), are used in research proposals to call attention to the new steps that your proposed work will take. By addressing problems that were left unsolved in the past, and by showing how your new approach will solve them, you underscore the creativity of your work. 

The course has many components, such as Chemistry and Society, Development of Industrial Chemistry, and Genealogy, to connect chemistry to history, world events, and real-case problems. Students are required to research resources such as journal articles, society news magazines, books, and patent literature to enhance skills in decision making, inter-... 

Process control books and journal articles tend to emphasize problems with a single controlled variable. In contrast, many processes require multivariable control with many process variables to be controlled. In fact, for virtually any important industrial process, at least two variables must be controlled product quality and throughput. In this section, strategies for multivariable control are considered. 

There are many excellent introductory books and journal articles on the subject of neural networks. Just a few of them are listed below in the references. Additionally, there are tutorials online at various web sites. However, the applications of neural network techniques to problems in molecular biology and genome informatics are largely to be found in scientific journals and symposium proceedings.

Another recent publication, List of Journal Articles by Bureau of Mines Authors Published July 1, 1910, to Jan. 1, 1960, mentions 9000 articles. It is complete with a subject and author index and is available from GPO for 1.75. Mineral Facts and Problems, an encyclopedia of U.S. minerals, is issued every five years. Latest edition (1960) sells for 6 (cloth) at GPO. 

They research information about their question, or problem. When gathering information, scientists use observation to watch what they are studying very carefully. They might write down, or record their observations when collecting the information. Scientists call this information data. They also collect data by reading other scientists books and journal articles. The Internet is another useful tool for gathering information. 

The next step is to consult the literature for information. Useful sources include books and standard methods from sources such as EPA, AOAC and ASTM, company literature, and journal articles. It is likely that other workers have faced situations similar or even identical to the problem at hand. It is interesting to note that difficult problems frequently garner more publications than easier problems. At this point, it should be possible to select an analytical method. The method selected is likely to reflect the personnel and equipment available and the worker s own preferences. The method selected need not be ideal a method that simply works is sufficient. It is also necessary to consider any modifications needed to apply the selected method to your own analytical problem. 

The first technical problem is encountered immediately upon beginning to test how well a periodic system concept agrees with the data. The problem consists of the surprisingly large errors that often accompany data in journal articles (occasionally as much as 20% for dissociation potentials and 100% for oscillator strengths of diatomic molecules). The errors are far less serious in quality critical tables.
