Initially, the jet diffuses in theway the same as a three-dimensional wall jet. Depending on the relative width of the channel a transition zone occurs, downstream of which the characteristics of the jet are akinto those of a plane wall jet...

Schofieldand Mrs L. Martin, The University o Ulster at f Jordanstown In describing ship behaviour in channels, the Author does notdistinguish between the action of orthodox screw-driven vessels and those which are towed by externally applied forces-factors which are of prime importance in considering these phenomena. Depending on the applied force, towed shipsare able to move in one of three speed ranges, namely the sub-critical, critical super-critical...

Rutenberg, Technion-Israel Institute of Technology, Haifa In this Paper, the transfer matrix of a uniform cantilever has been used to formulate the free vibration problem of an outrigger-braced core structure. The general formulation of the problem considers shear deformation, rotatory inertia, and the additional massof the outrigger itself. As is well known, these effects are usually of minor significance for the lower vibration modes of slender tall buildings...

Chana, Cement and Concrete Association The Authors have presented some interesting test data which indicate that the shear capacity is considerably reduced if the main tension bars are positioned in briefly the top of the section when the concrete poured. I would like to comment is on three aspects of the Authors' Paper, namely the significance and analysisthe of results and the possible reasons the reduction in strength...

Chen Professor D. I. H. Barr, University ofStrathclyde The Author attributes equation(7) to Blasius, but without specific citation. However, the most commonly quoted Blasius'' smooth turbulent formula as follows is f = 0.3164Re-0"5 (25) 21. Although the general form of equation (7) was indeed proposed by Blasius directly, I have shown" that much earlier this form was indirectly also proposed by Reynolds...

Bulman, Consultant The Authorhas presented an ingenious method of transforming a unit hydrograph to an adjacent site using an extension of the S-curve. Unfortunately, this does not overcome the inherent disability of the unit hydrograph in its contradiction of hydraulic theory. 24. While the unit hydrograph may be a useful tool within the range of events from which it is derived, there are serious dangers to be considered before extrapolating from it...
