SOAs are important components for optical communication systems with applications as in-line amplifiers and as functional devices in evolving optical networks. The functional applications of SOAs were first studied in the early 1990's; since then, the diversity and scope of such applications have been steadily growing. Semiconductor Optical Amplifiers is self-contained and unified in presentation.

Other migrants tell of the corpses they pass--bodies that are never recovered or counted. Crossing With the Virgin collects stories heard from migrants about these treacherous treks--firsthand accounts told to volunteers for the Samaritans, a humanitarian group that seeks to prevent such unnecessary deaths by providing these travelers with medical aid, water, and food. Other books have dealt with border crossing; this is the first to share stories of immigrant suffering at its worst told by migrants encountered on desert trails. The Samaritans write about their encounters to show what takes place on a daily basis along the border: confrontations with Border Patrol agents at checkpoints reminiscent of wartime; children who die in their parents' desperate bid to reunite families; migrants terrorized by bandits; and hovering ghost-like above nearly every crossing, the ever-present threat of death. These thirty-nine stories are about the migrants, but they also tell how each individual author became involved with this work. As such, they offer not only a window into the migrants' plight but also a look at the challenges faced by volunteers in sometimes compromising situations--and at their own humanizing process. Crossing With the Virgin raises important questions about underlying assumptions and basic operations of border enforcement, helping readers see past political positions to view migrants as human beings. It will touch your heart as surely as it reassures you that there are people who still care about their fellow man."- from eBook Central 606 $aUndocumented immigrants$zMexican-American Border Region 606 $aHumanitarian assistance$zMexican-American Border Region 606 $aBorder crossing$zMexican-American Border Region 607 $aUnited States$xEmigration and immigration$xSocial aspects 607 $aMexico$xEmigration and immigration$xSocial aspects 608 $aElectronic books. 615 0$aUndocumented immigrants 615 0$aHumanitarian assistance 615 0$aBorder crossing 676 $a304.8/730720922 700 $aFerguson$b Kathryn$0990892 701 $aPrice$b Norma A.$f1942-$0990893 701 $aParks$b Ted$f1955-$0990894 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910452073103321 996 $aCrossing with the Virgin$92267287 997 $aUNINA 999 $p$63.00$u04/13/2016$5Soc LEADER 00988nam a2200265 i 4500 001 991000755509707536 005 20020509175003.0 008 931215s1982 it ||| | ita 035 $ab11405235-39ule_inst 035 $aPARLA214818$9ExL 040 $aIstituto di Filosofia$bita 100 0 $aTommaso :$cd'Aquino $0452087 245 12$aL'uomo e l'universo :$bOpuscoli filosofici /$cTommaso d'Aquino.
