Sommario/riassunto

""3-D modeling and inversion is a reality, and not an illusion."" This is the clear conclusion of the Second International Symposium on Three-Dimensional Electromagnetics held at the University of Utah in 1999. Containing papers submitted by 36 authors, this volume, by the sheer number of works, their diversity, and the truly international character of the efforts attests to the vigor with which the problems of the field are pursued today. The papers in this book are grouped in three parts: 3-D EM modeling; 3-D EM inversion; and 3-D EM in practice. They cover a wide range of to

Sommario/riassunto

Previously published (2014 Forever More Publishing. Being a loner, moving by herself from a city to a small town, is something Rikki is more than capable of handling. Having a strong hunk who offers to help with the heavy lifting was just an added bonus. And one she couldn't pass up.Torger had sat at the coffee shop across the street and watched the woman who'd snagged his interest carry boxes out of a moving trailer before he could no longer stay away. His interest in her is a sign his vampire side considered her a mate. Once he had her scent in his nose, his werewolf one agreed.With his vampire side of the family still hunting him, his sister and brother, Torger knows he puts Rikki at risk, but there is no denying the mating instincts of a hybrid. Even though his closeness to her puts a target on her back.

Sommario/riassunto

Famiglia, ancora famiglia. Mentre l'oggetto, gli oggetti che sono compresi entro questo grande denominatore mutano e si differenziano sempre di più, il nostro parlarne e il nostro comprendere fatica a inseguire l'universo polimorfico dei legami familiari, una volta detti "di sangue", oggi forse di fatto, e, in forme ancora oscure, di geni. La diade natura/cultura stenta a conservare il suo doppio regime di competenza. Oggi i processi biologici di formazione delle discendenze, delle consanguineità e delle affinità attraversano spavaldamente il confine che un tempo separava il mondo del bios da quello del logos, così come la distinzione fra legge ( by law ) e sentimento, love. Un intenso lavoro di osservazione e passione classificatrice esplora oggi su scala globale, nella ricerca bio-genetica, le piste ramificate della genesi delle popolazioni, e delle etnie, dissolve le identità di razza e ne polverizza i residui in una rete sconfinata di incroci e meticciati. I saggi riuniti e amalgamati in questo volume attraversano diversi scenari di

espressione della identità di appartenenza, delle identità di discendenza e del loro destrutturarsi: in Europa, in India, nel Nuovo Mondo. I paradigmi della parentela, la genealogia, le affinità vengono qui esposti alle prove dei mutamenti del nostro tempo: famiglie di fatto, famiglie ricomposte, relazioni ex e parentele step in un confronto insistente con i dati in progress della ricerca genetica e con la passione amatoriale della parentela postmoderna.
