Convergence of Infinite Series (open access)

Convergence of Infinite Series

The purpose of this paper is to examine certain questions concerning infinite series. The first chapter introduces several basic definitions and theorems from calculus. In particular, this chapter contains the proofs for various convergence tests for series of real numbers. The second chapter deals primarily with the equivalence of absolute convergence, unconditional convergence, bounded multiplier convergence, and c0 multiplier convergence for series of real numbers. Also included in this chapter is a proof that an unconditionally convergent series may be rearranged so that it converges to any real number desired. The third chapter contains a proof of the Silverman-Toeplitz Theorem together with several applications.

Relationship Between Self-Reported Stress Levels and Job Satisfaction Among Elementary and Secondary School Principals (open access)

Relationship Between Self-Reported Stress Levels and Job Satisfaction Among Elementary and Secondary School Principals

The problem with which this investigation is concerned is that of determining the nature of the differences and relationships between self-reported levels of stress and job satisfaction of elementary and secondary school principals in a selected school support region. This research effort employed a co-relational design. A random sample of 100 elementary and 100 secondary school principals were selected to participate in the study, for which the response rate was 93 per cent. The principals were mailed the Morse Index of Employee Satisfaction and the Spielberger State-Trait Anxiety Inventory, Part A, and asked to assess their own job satisfaction and stress levels.

Factors Influencing Nigerian Adults to Participate in the Adult Basic Education Programs of the Nigerian Baptist Convention Which Lead to the First-School-Leaving-ertificate (open access)

Factors Influencing Nigerian Adults to Participate in the Adult Basic Education Programs of the Nigerian Baptist Convention Which Lead to the First-School-Leaving-ertificate

The problem with which this study is concerned is that of determining the specific stated factors that influenced Nigerian adults to participate in adult basic educational programs of the Nigerian Baptist Convention which lead to the first-school-leaving-certificate. The purpose of the study was to identify and examine the factors that influence Nigerian adults to participate in the adult basic and certificate educational programs of the Nigerian Baptist Convention, and to make recommendations for program improvements based on these findings. The data for this study were collected from questionnaires which included demographic information about the participants and a list of reasons for educational participation and needs-met statements. Questionnaire items were rated on a five-point scale. The researcher mailed 600 questionnaires to both adult basic and certificate education students in the adult education programs of the Nigerian Baptist Convention in Ibadan, Nigeria. The basic education group responded to 126 questionnaires, while the certificate groups responded to 122 questionnaires.

Tunnel nitrogen spill experiment (open access)

Tunnel nitrogen spill experiment

The Energy Saver Safety Analysis Report (SAR) found the tunnel oxygen deficiency considerations emphasized helium spills. These reports concluded the helium quickly warms and because of its low denisty, rises to the apex of the tunnel. The oxygen content below the apex and in all but the immediate vicinity of the helium spill is essentially unchanged and guarantees an undisturbed source of oxygen especially important to fallen personnel. In contrast nitrogen spills warm slower than helium due to the ratio of the enthalpy changes per unit volume spilled spread more uniformly across the tunnel cross-section when warmed because of the much smaller density difference with air, and generally provides a greater hazard than helium spills as a result. In particular there was concern that personnel that might fall to the floor for oxygen deficiency or other reasons might find less, and not more, oxygen with dire consequences. The SAR concluded tunnel nitrogen spills were under-investigated and led to this work.

(4+2)-Cycloaddition Reactions of Ketenes; Pyranones (open access)

(4+2)-Cycloaddition Reactions of Ketenes; Pyranones

This study deals with the (4+2)-cycloaddition reactions of 4-Ï€ electron compounds with ketenes. Chloroketenes were generated in situ from the corresponding chlorinated acid chlorides in the presence of the ketenophiles. Chloro-, dichloro- and diphenylketenes reacted with 1-methoxy-3-trimethylsiloxy-l,3-butadiene, and 2,4-bis(trimethylsiloxy)-1,3-pentadiene to yield the corresponding dihydropyrans. The dihydropyrans yielded substituted 4-pyranones on hydrolysis.

Effect of grain size on the mechanical properties of dual phase Fe/Si/C steels (open access)

Effect of grain size on the mechanical properties of dual phase Fe/Si/C steels

For an Fe/2Si/0.1C steel with an intermediate quenching heat treatment, it was found that as the prior austenite grain size is refined, significant improvements in total elongation, reduction in area and impact toughness can be achieved, while uniform elongation, yield and tensile strengths are not affected. These improvements are analyzed in terms of microstructure and fracture characteristics. The cleavage cracks propagate nearly straight without deviation at the ferrite/martensite interfaces within the sub-units of the DFM structure, but change their path at high angle sub-unit boundaries. The crack is less likely to be deflected at the ferrite/martensite interface because the interface is coherent. Comparison of optical micrographs and SEM fractographs has shown that there is close agreement between the sub-unit size and cleavage facet size. The observations lead to the conclusion that the sub-unit size is the basic microstructure unit controlling the fracture behavior of DFM steels produced by the intermediate quenching heat treatment. A controlled rolling process was undertaken to obtain grain refined DFM steels. Results showed that this produces micro-duplex structures with attractive mechanical properties in an economicl way.
