The material for the entire wing structure is AL2024-T3. The compressive strength of the material is equal to tensile strength of the material. In rib sizing section‚ the cross section of the wing is constant that the wing thickness and chord are wing root thickness and mean geometric chord length to simplify the sizing process

including the unit weight and the compressive strength has been reported based on the variation in its ingredient proportions. The unit weight of EPS composite soil‚ which ranges from 5 to 18 kN/m3‚ is lighter than that of natural soils because of adding super-light EPS into the mixture. The reported values of compressive strength are in the range of 50~550kPa‚ which meet almost all the requirements for fill materials. Both the unit weight and the compressive strength of this geomaterial can be easily adjusted

either socially‚ physically or financially. Constraints can be found in various forms for instance with respect to our project the constraints are both social and physical. The materials chosen have been checked with respect to their load bearing capacities as earlier during market research it was found that there are two materials abundantly available which were steel and aluminum. Since steel was found in various shapes and sizes in comparison to aluminum and more importantly its load bearing capacity

DEVELOPMENT OF MAXIMUM SPRINTING SPEED By Frank W. Dick‚ BAAB Director of Coaching‚ Great Britain The 15th Annual Congress of the European Athletics Coaches Association (held in East Germany last January) focused on sprints and hurdles. We are fortunate to have this contribution firom EACA president and British director of coaching Frank Dick. Dick analyzes the Seoul 100m results and points out the important differences in sprint technique and training between men and women. REPRINTED FROM TRACK

to show the difference between Mohr-Coulomb and Hoek-Brown‚ in addition‚ describes the relation between the seismic force and rock slope stability. Currently‚ the Hoek-Brown failure criterion is widely accepted approach to estimating rock mass strength and it applicability of this criterion is suited to isotropic and homogeneous intact rock‚ or heavily jointed rock masses. However‚ for the most geotechnical software applied to rock slopes‚ still are based on the Mohr-Coulomb failure criterion

Composite microspheres with noble metal nanoshells have great advantages in catalysis‚ optics‚ conductivity‚ chemical sensors‚ and so on [1–5]. Moreover‚ these hybrid materials can prevent noble metal nanoparticles from agglomerating without the use of a stabilizer and can be easily retrieved‚ owing to the relatively large size of the supports. In particular‚ silver‚ with its outstanding combination of properties‚ has continued
