To my two girls, Angela and Stephanie The first half of the year 2009 was the hardest time in my life — a trip through hell and back. I cannot thank Angela enough for all her love and support she gave to me. Without her I couldn’t have made it through that. Stephanie was born shortly after medical treatment and was the biggest motivation during that time. I love you both! —Christian Nagel To Tuija, always. —Bill Evjen For donna —Karli Watson Dedicated to my parents, Joan & Donald Skinner. There are many things that I’d like to say to my Mum and Dad, but I’m in the privileged position of not needing to say anything to them. They were both wonderful people, are greatly missed, and the world was made a sweeter place by their being in it. Thanks Mum, thanks Dad, you were brilliant. —Morgan Skinner [...]... 41 2 41 3 41 9 41 9 42 0 42 0 42 1 42 1 42 2 42 2 42 2 42 3 42 3 III S 42 4 42 6 42 7 43 1 43 1 43 2 43 2 43 3 43 4 43 4 43 4 43 4 43 5 43 5 43 6 43 8 44 1 44 5 44 5 44 6 44 6 44 7 44 7 44 8 44 8 44 9 45 0 45 1 45 2 XXiV 45 2 45 3 45 4 45 5 45 5 45 6 45 7 45 8 45 8 S 46 1 46 1 46 3 46 4 46 5 46 5 46 7 46 8 46 9 47 0 47 1 47 2 47 5 47 6 47 7 47 8 47 9 47 9 48 3 48 3 48 4 48 6 48 8 48 9 49 2 49 2 49 3 49 3 49 4 49 5 49 6 49 7 49 8 49 9 49 9... 2 84 285 286 287 288 289 289 290 290 291 293 2 94 295 295 296 297 300 302 302 3 04 305 I S II 307 307 308 309 311 312 313 3 14 315 317 317 325 329 332 333 3 34 3 34 337 340 340 342 344 345 349 351 352 353 355 359 359 360 360 362 363 3 64 367 369 S 373 373 378 383 386 386 3 94 398 40 1 40 3 40 4 40 4 40 5 40 6 t 40 7 40 7 40 8 40 8 40 9 40 9 41 0 41 1 41 1 41 2 41 2... 23 23 24 24 25 26 27 28 29 31 31 31 33 33 35 37 37 40 43 44 45 46 47 48 48 49 O 50 51 53 53 53 55 55 56 57 57 57 58 58 I 58 59 64 S 65 65 66 66 67 78 79 80 81 82 82 82 84 84 84 85 86 87 89 89 89 90 90 90 91 92 93 93 94 94 99 99 99 100 101 1 04 105 II S 107 107 108 109 109 109 110 110 113 1 14 1 14 117 117 118 118 119 120 121 123 1 24 125 126 126... 731 732 732 733 7 34 735 736 739 741 742 744 744 745 747 747 7 54 755 759 S 760 762 7 64 765 767 769 771 772 775 775 780 780 781 7 84 7 84 786 787 788 789 793 799 800 802 802 803 805 806 806 808 810 8 14 817 817 818 818 I S 819 820 821 822 8 24 825 826 829 832 835 835 840 842 844 850 850 851 852 852 8 54 855 855 857 859 860 k 861 861 862 II 863 8 64 865 866 867 867... 502 503 5 04 5 04 506 507 507 507 509 510 510 513 5 14 515 520 521 522 522 523 5 24 526 529 530 533 5 34 535 539 543 545 545 545 547 547 548 I 552 5 54 556 558 561 562 S F 562 567 568 569 569 570 570 5 74 578 579 579 579 580 581 5 84 5 84 588 590 590 591 591 593 5 94 5 94 598 598 600 600 601 601 603 605 605 606 607 607 609 609 II S 610 611 612 6 14 616 618 6 24 626 627... 133 1 34 1 34 135 136 139 139 140 III 140 S 141 141 142 146 147 149 151 151 153 157 157 158 161 162 162 163 163 1 64 165 171 172 173 179 182 183 183 1 84 185 188 190 190 193 196 197 198 198 199 200 XiX S 200 202 203 205 207 208 209 211 212 217 218 219 221 223 2 24 225 225 226 228 236 236 240 241 246 248 248 250 253 2 54 255 256 258 XX 258 260 262 2 64 266...
