I?-Turns

I have not kept records of the lectures I gave during my career at seminars, symposia, meetings, and congresses or at different universities around the world. There were many, and although these days I turn down most invitations, I still lectnre regularly (but more selec-... 

Figure 2.8 Adjacent antiparallel P strands are joined by hairpin loops. Such loops are frequently short and do not have regular secondary structure. Nevertheless, many loop regions in different proteins have similar structures, (a) Histogram showing the frequency of hairpin loops of different lengths in 62 different proteins, (b) The two most frequently occurring two-residue hairpin loops Type I turn to the left and Type II turn to the right. Bonds within the hairpin loop are green, [(a) Adapted from B.L. Sibanda and J.M. Thornton, Nature 316 170-174, 1985.]...

Dislocations are involved in various important aspects of materials apart from mechanical behaviour, such as semiconducting behaviour and crystal growth. I turn next to a brief examination of crystal growth. 

The great disadvantage of any battery, however advanced, for automobile power trains, is the long time required to charge a battery, and in my view this will be decisive. Here, fuel cells have an enormous advantage over batteries, and so I turn to fuel cells next. 

The four major quantities on which we will focus are atomization energies, electro afiinities, ionization potentials and proton affinities. We ll look at each of them i turn in this section. Note that all of them are conventionally defined to be greater tha...

Stanley G. Thompson joined my group on October 1, 1942 and it fell to his lot to discover the process that was chosen for use at Clinton Laboratories (in Tennessee) and the Hanford Engineer Works (in the state of Washington) for the separation of plutonium from uranium and the immense intensity of radioactive fission products with which it was produced in the nuclear chain reactors. Again I turn to my journal to tell the story ... 

An acid is classically known as a substance whose aqueous solution (i) turns blue litmus red (ii) neutralizes bases (iii) reacts with active metals with the evolution of hydrogen and (iv) possesses a sour taste. A base is again classically known as a substance which in aqueous solution (i) turns red litmus blue (ii) neutralizes acids (iii) tastes offensive and (iv) gives a soapy feel. These given descriptions of acids and bases may also be regarded as being operational or or experimental definitions. 

I do not sleep so well, these days, and wake early. This morning I stood watching the sun rise over the Fosse and Sheriff Hutton village, and listening to more noise of business from below than I have been accustomed to hear so early in these long days. When the sun had risen in all its blind glory, I turned away. 

Had my time come already I wondered, as it faded. We had not yet made preparation for my lying-in. Perhaps it would pass if I lay quietly and went on with my prayers. When they were done I turned my head, and looked toward the tapestry of Melusina that my mother, as good as her word, had caused to be made and hung above my bed. Melusina in her dragon form, her ancestress and... 

Of course, he says, and vanishes. For a mad moment I wonder if it s my hallucination haunting me that I ve dreamed him. Then I turn and look at Uncle Gareth. 

They gathered up their skirts and backed away, hesitantly. I turned my back on them and made for the paddocks and trees beyond the stables. 

Let s go and find a drink, says Uncle Gareth quickly. I turn aside to wipe my eyes discreetly. It s all in the workshop, Mark. He leads the way, though the back-door latch rattles for a moment before he lifts it. 

While he bent to lower the bag to the ground, I turned so as to come down backwards, feet and hands moving independently, childlike, monkeylike I d been climbing trees all my life. But then... 

Mon seigneur It was Louis s voice. I turned. Milord le Connetable would have speech with you. He has word from the Mayor. ... 

Sire Sire I turned. Ned had escaped his nurse and was galloping over the cobbles as fast as his fat little legs would go. Is froggies Come and see ... 

And then the up train was signaled and I had to hurry. Usually Uncle Gareth would have got a platform ticket and helped me onto the train with my bags, and stayed to wave me off. But when I turned around from the ticket-office window, he d gone.
