Ultraviolet energy has been used in the past to disinfect drinking water and fruit juice. This paper will discuss the impact of ultraviolet energy on strawberry shelf life. The ultraviolet tunnel used in the study utilizes lamps that are designed to emit specific narrow wavelength spectrum, of 253.7 nanometers. The tunnel was made of polished aluminum and reflects beams of energy within the tunnel. Ultraviolet energy can improve food safety by destroying the microorganisms, such as E coli and salmonella that cause food-borne illnesses. Ultraviolet energy can extend shelf life of produce and make it possible to keep these foods for greater periods of time while keeping the integrity of the berry intact. A review of literature was conducted to identify the pathogens that affected this study, these pathogens were: Grey Mold, Botrytis cinerea ; Dry Crown Rot Botryotinia fuckeliana ; Phomopis Leaf Blight, Phomopsis obscurans and Dendrophoma obscurans ; Rhizopus Rot (leak), Rhizopus stolonifer ; and Tan-brown rot, Discohainesia oenotherae . It was found that ultraviolet viable application range rate were 88.1mj/cm3, 140mj/cm3, 191.9mj/cm3, 243.8mj/cm3, 295.7mj/cm3 and 347.6mj/cm3 lasted longest and these rates were used in the full test run. Results indicated that a significant shelf life extension of strawberries was achieved at each of these treatment levels. The average shelf life of non-treated berries was 14.9 days whereas the average treated strawberries range from 17.25 to 20.9 days. A lowest level of treatment was reached at 15 seconds or 88mj/cm3. A statistical relationship between application rates and shelf life was determined. Using an ANOVA table at 95% confidence interval, it was determined when all samples, as individuals, were considered that the shelf life was extended by exposure to ultraviolet energy. Another ANOVA table was used for each treatment group versus the control group, all treatment groups showed a significant difference opposed to the control group. In conclusion, this study shows that applying ultraviolet energy to strawberries significantly improves shelf life. There was not a significant benefit to exposing the strawberries to added ultraviolet energy.

Observations from 1995 and 1996 described the seasonal evolution of the threedimensional density field in the western Irish Sea. A cold, dense pool flanked by strong nearbed density gradients was present from May until October. Temperature had the dominant effect on density from June onwards. The trajectories of 55 satellite-tracked drifters defmed the full spatial extent of the cyclonic circulation that is the western Irish Sea gyre. Several distinct recirculation paths were observed and drifter speeds were in good agreement with geostrophic calculations based on the observed density field. The existence of such organised, baroclinic flows in shelf seas demands that coastal ocean models should reproduce their dynamics correctly, if the models are to be useful as environmental management tools. One such model, ECOMsi, was applied to the study area and results from seasonal simulations were compared with the observations. A new technique was developed to perform quantitative comparisons between modelled and observed flow fields. The model successfully reproduced the three-dimensional temperature structure throughout the seasonal simulations, and also predicted the cyclonic, near-surface residual circulation of the gyre. The model demonstrated conclusively that the gyre is density-driven and revealed the same recirculation paths that were visible in the drifter tracks. The vertical structure of the modelled density-driven flow confirmed the geostrophic nature of the currents and emphasised the important dynamical role of sharp density gradients near the bed (bottom fronts). A quantitative comparison of different model runs identified the critical parameterisations and forcing quantities for this application. An accurate specification of air temperature over the sea region was required for the model to achieve the correct timing of the stratification breakdown. During this phase, convective cooling at the surface was seen to be as important as the mixing by autumnal winds in eroding the density structure. The possibility of a seasonal reversal in density-driven flow along the east coast of Ireland was also identified. A new interaction between the wind and the density field, which could defme where the strongest currents in the gyre are to be found, is described. The model is now considered to be sufficiently well tested to use in a predictive capacity and for biological transport studies. This work highlights the benefits that can be obtained using high quality spatial and temporal field observations in the critical testing of numerical models, and furthermore suggests that shelf seas are the perfect location for such tests to be performed.

The objective of this study was to determine the effects of feeding endophyte-infected tall fescue seed to Angus steers during the stocker phase on beef shelf life. Endophyte-infected tall fescue seed had no effect on pH, TBARS, activity of superoxide dismutase and metmyoglobin reductases, and sensory attributes of strip loin steaks or patties (P >= 0.082). However, E+ patties had 0.5% more DMb (P = 0.017) and 27% greater redness (a*) on d 5 of display (P < 0.001). Retail display of steaks decreased lightness (L*), redness, oxymyoglobin percentage (OMb), and MRA from 45.01, 32.60, 67.61%, and 9.54 µM/min/g on d 0 to 40.11, 21.83, 48.95%, and 2.30 µM/min/g, respectively on d 7 (P <= 0.001). Retail display of patties decreased L*, OMb, and, MRA from 52.30, 64.04%, and 5.56 µM/min/g on d 0 to 48.88, 58.5%, and 2.16 µM/min/g, respectively on d 5 (P <= 0.001).

The purpose of this study was to clarify the ambiguity in the law relating to the extended continental shelf in Article 76 of the 1982 United Nations Convention on the Law of the Sea. Another aim was to study the application of the law in a more focused part of the world, the region of East Asia, and in particular, Malaysia. The study also sought to propose solutions to issues relating to the extended continental shelf. The history of the law relating to the continental shelf, the codification of the law, and the enforcement of the law by the Commission on the Limits of the Continental Shelf is presented. Besides that, Article 76 was also thoroughly discussed in order to identify the problems involved. Besides that, the two biggest issues which determine the outer limits of the continental shelf are examined. These are issues relating to ridges and submarine elevations and the application of the foot of continental slope provisions. The study examined the problems involved with the legal and scientific interface found in Article 76 and addressed them by referring to the legislative history of Article 76, State practice and the practice of the Commission. The continental shelf in the East Asian region is also analysed in order to provide an overview of the continental shelf issues in the region. Special reference to Malaysia is made as a State that has made a submission on its outer limits of the continental shelf. A thorough analysis was made based on the findings made in this study. This study also explored possible solutions to the continental shelf issues discussed.

International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / The rapid technology growth in the aerospace industry continues to manifest itself in increasingly complex computer systems and weapons systems platforms. To meet the data processing challenges associated with these new weapons systems, the Air Force Flight Test Center (AFFTC) is developing the next generation of data acquisition and processing systems under the Advanced Data Acquisition and Processing Systems (ADAPS) Program. The ADAPS program has evolved into an approach that utilizes Commercial-Off-The-Shelf (COTS) components as the foundation for Air Force enhancements to meet specific customer requirements. The ADAPS program has transitioned from concept exploration to engineering and manufacturing development (EMD). This includes the completion of a detailed requirements analysis and a overall system design. This paper will discuss the current status of the ADAPS program including the requirements analysis process, details of the system design, and the result of current COTS acquisitions.
