The load over an elliptical wing with 30 degrees sweepback has been calculated by a method, based on vortex theory, which takes account of the chordwise distribution of lifting area. The theory indicates a 14-percent loss in total lift due to the introduction of sweepback, with the greatest loss taking place at the center of the span. An increase in concentration of load at the tips is also indicated. The results are compared with the results previously obtained by somewhat simpler calculations based on the assumption of a single lifting vortex.

This text introduces and draws together pertinent aspects of fluid dynamics, physical oceanography, solid mechanics, and organismal biology to provide a much-needed set of tools for quantitatively examining the biological effects of ocean waves. "Nowhere on earth does water move as violently as on wave-swept coasts," writes the author, "and every breaker that comes pounding on the shore places large hydrodynamic forces on the organisms resident there." Yet wave-swept coral reefs and rocky shores are home to some of the world's most diverse assemblages of plants and animals, and scientists have chosen these environments to carry out much of the recent experimental work in community structure and population dynamics. Until now these studies have been hampered because biologists often lack a working understanding of the mechanics of the wave-swept shore. Mark Denny here supplies that understanding in clear and vivid language. Included are an introduction to wave-induced water motions and the standard theories for describing them, a broad introduction to the hydrodynamic forces these water movements place on plants and animals, and an explanation of how organisms respond to these forces. These tools are put to use in the final chapters in an examination of the mechanisms of "wave exposure" and an exploration of the mechanical determinants of size and shape in wave-swept environments.

The ancient prophets were a different breed. Though embedded in the midst of the people, administering and serving in much the same capacity as their counterparts, an inner longing to know set them apart. It was not enough to be a minister of the Lord; they wanted to know the intent of the one for whom they ministered. For them the morning sunrise was the beginning of another days inquiry, an inner desire to belie life on a rock eternal. It is through them the Creator finds voice, as the prophet scans the worlds panorama with spiritual eyes, ever longing that all people would see what they see and understand what is heard. It is the cry Moses had for Israel, that all would be prophets. Above all, you must understand that no prophecy of Scripture came about by the prophets own interpretation. For prophecy never had its origin in the will of man, but men spoke from God as they were carried along by the Holy Spirit (2 Peter 1:2021 NIV). The Bible is both history and a prelude of history with an impeccable purpose. It does not deviate in dealing with three objectives: the fall of humanity, its redemption, and final liberation. As a worlds best seller, it is faulted for removing the mystique, updating and critiquing future events only as those events occur. Until the Bible deliberates, the archives of world history are mere fillers of rampant human instinct. But its final resolution is here, with immense biblical documentation, with the promise to be understood by all people. Keeping in mind that Gods intent remains to redeem and liberate, even to the very door of human extinction.

Span load distributions of swept-back wings have been calculated. The method used was to replace the wing with a bound vortex at the quarter-chord line and to calculate the downwash due to the system of bound and trailing vortices to conform at the three-quarter-chord line to the slope of the flat-plate wing surface. Results are given for constant-chord and 5:1 tapered plan forms, for swee-pback angles of 0, 30 and 45 degresss, and for aspect ratios of 3, 6, and 9. Some comments on the stalling of swept-back wings are included.
