    Effect of Apples on Serum Cholesterol Levels in Humans
    Seventy-six free living male volunteers in the age group 30 to 50 years were paired in two groups based on similar cholesterol levels. Each individual in one group ate at least two apples per day over the period November 17 to March 10 while the corresponding individuals in the other group ate only three apples, or their fruit equivalent, per week. No other dietary control was exerted on the subjects. Serum cholesterol levels were measured every 3 to 4 weeks during the experiment and the apple group had consistently lower mean levels, significantly so on the last two analysis dates, than the 'non' apple group. The largest difference found in mean serum cholesterol levels between the groups was 8.1%. The results of this experiment could have application in the context of long-term modification of dietary patterns in relation to heart disease risk both in a general community sense and also in hyperlipidaemic subjects.

    Definition of a useful minimal-set of accurately-specified input data for Building Energy Performance Simulation
    Developing BEPS models which predict energy usage to a high degree of accuracy can be extremely time consuming. As a result, assumptions are often made regarding the input data required. Making these assumptions without introducing a significant amount of uncertainty to the model can be difficult, and requires experience. Even so, rules of thumb from one geographic region are not automatically transferrable to other regions. This paper develops a methodology which can be used to determine useful guidelines for defining the most influential input data for an accurate BEPS model. Differential sensitivity analysis is carried out on parametric data gathered from five archetype dwelling models. The sensitivity analysis results are used in order to form a guideline minimum set of accurately defined input data. Although the guidelines formed apply specifically to Irish residential dwellings, the methodology and processes used in defining the guidelines is highly repeatable. The guideline minimum data set was applied to practical examples in order to be validated. Existing buildings were modelled, and only the parameters within the minimum data set are accurately defined. All building models predict annual energy usage to within 10% of actual measured data, with seasonal energy profiles well-matching.

    Comparison of The Quality of Irish and French Grown Golden Delicious Apples
    (An Foras Talúntais, 1977) ;
    The quality of Irish and French grown Golden Delicious apples, purchased at retail outlets in Dublin, was compared in 1974-75 and in 1975-76. The French Goldens were on average about 48 and 28% more expensive per kg than the Irish in 1974-75 and 1975-76 respectively. The main quality difference between fruit from the two sources was in colour, the French fruit being green and the Irish, green-yellow to golden. The French Goldens were generally larger and had a higher juice yield while the Irish were firmer and had more ribbing. On average, there was no taste panel preference for fruit from either source and there were only small differences in soluble solids, acidity and bruising.
