A Study of Sample Size in Macadamia Nuts (Macadamia Integrifolia)
Replicated samples of 10, 20, 30, AO, and 50 in-shell macadamia nuts were set up to determine optimum sample size needed to determine the number of nuts necessary to obtain acceptably reliable values for percent grade 1 kernels, percent kernel, and average shell diameter. Average shell diameter was found to be most variable with an average coefficient of variation of 150 percent for the 5 sample sizes. A 30 nut sample was necessary for +3 percent accuracy at the 95 percent probability level. The lowest average coefficient of variation found in the experiment was 2.4 percent for percent kernel. A 30 nut sample was required for accuracy of +2 percent at the 95 percent probability level. The average coefficient of variation for percent grade 1 kernels was 7.3, and a 100 nut sample was required for accuracy of +5 percent, at the 95 percent probability level
Entrepreneurship: One Key To Integrated Business Education
This paper presents a case study of the key issues in implementing an innovative approach to teaching the business core curriculum. The program utilizes entrepreneurship as a key integrating theme and is designed to include two major active learning components: the development of a business plan and the implementation of a student business. The course integrates cross-functional topic areas including accounting, finance, international business, management, and marketing. The paper describes the program in detail and identifies the key challenges and opportunities that remain. From the student and faculty feedback it appears obvious that while certain improvements need to be made and institutional resources increased, the course offers a unique educational experience
Mapping and Analysis of Coral Reef Damage Related to Boating in Kāneʻohe Bay with Unmanned Aerial Systems
MA University of Hawaii at Manoa 2016Includes bibliographical references (leaves 63–71).Low-cost unmanned aerial systems have been underutilized in mapping damage to coral reefs due to recreational boating activities. The need for fast and accurate mapping is important when making sense of situations where coral reefs require emergency restoration and damage assessments.
With coral reefs under increasing stress from global climate change and other anthropogenic factors, the need to protect them is more important than ever. There are inherent challenges in mapping benthic habitats with typical methods such as scuba surveys and satellite photo interpretation. This study aims to use unmanned aerial vehicles to map damage to coral reefs related to boating in Kāneʻohe Bay. Images were taken at relatively low altitudes from an unmanned aerial vehicle and then mosaicked together using commercially available software. The image orthomosaics were georeferenced and digitized into vector files for further analysis. The vector files can reveal patterns and concentrations of vessel related damage to coral reefs in the bay. Continued data collection can serve to monitor damage and predict future locations of boat interactions with these important marine resources

Swelling behaviour of unsaturated fine grained soils
The aim of this research was to investigate the swelling behaviour of unsaturated fine grained soils by means of various laboratory tests such as a 100 mm stress path triaxial cell and a computer controlled oedometer. Centrifuge modelling was used as a link between the laboratory tests performed and an existing prototype experimental wall. Three types of soils with different plasticity have been tested simulating the boundary conditions that act on a soil element behind a stiff wall. Therefore the laboratory equipment was designed or modified to enable the measurement of the swelling pressure of the soil under conditions of lateral confinement. The results show that the swelling behaviour of these soils is controlled by the testing conditions imposed on the soil as well as the initial state of the soil as described by dry density and water content. Suction measurements made using the filter paper method, showed that dry density and water content can be used instead of specific volume and suction when defining the state of an unsaturated soil. The results from the centrifuge model tests, in which soil was compacted behind a stiff instrumented wall, showed that measurements of lateral stress change on the model wall were consistent with the swelling behaviour observed in the laboratory tests as well as in a previous full scale prototype test. Analysis of the experimental data indicated a possible method of extending the current specification set in the United Kingdom (Manual of Contract Documents for Highway Works, 1991) for the use of fine grained soils as backfill material near to structures

Critical behaviour of thin films with quenched impurities
The critical behaviour of thin films containing quenched random impurities
and inhomogeneities is investigated by the renormalization-group method. The
finite-size crossover in impure films has been considered on the basis of the
fundamental relationship between the effective spatial dimensionality and the
characteristic lengths of the system. The difference between the critical
properties of infinite systems and films is demonstrated and investigated. A
new critical exponent, describing the scaling properties of the thickness of
films with extended impurities has been deduced and calculated. A special
attention is paid to the critical behaviour of real impure films.Comment: 27 pages LaTex; figures are available in the journal varian
