An Interdisciplinary Journal of Research, Theories, and Observations
Volume 22, Number 1
A Semi-Annual Publication of Akamai University
The Pacific Journal of Science and Technology (PJST) is a peer-reviewed electronic journal of interdisciplinary scientific research, theories, and observations. PJST is a semi-annual publication of Akamai University (Hilo, Hawaii and Durham, North Carolina). The mission of this journal is to provide a non-commercial platform for the dissemination of scientific research and theory across the academic disciplines. We seek to facilitate greater communication between the scientific assembly at Akamai University and the larger scientific community. To this end, the PJST provides a platform for research conducted both inside and outside of our university. As a non-profit institute of higher learning, Akamai University seeks no distribution or subscription fees from the PJST. The journal is provided strictly in the spirit of academic and scientific discourse and in support of our institutional mission of improving the human condition.
