We explore the conservation of orbital angular momentum (OAM) in the four-wave mixing (FWM) process in hot rubidium vapor. Since most modern communication systems send data in pulses corresponding to bits, we can use OAM to encode more information in each pulse by assigning structure to each signal. Furthermore, because FWM can be used to generate entangled photon pairs, we can use this process to bring enhanced signal security. We experimentally studied FWM with a wide range of Laguerre-Gaussian modes and their superpositions and observed OAM transfer from the probe field to a generated Stokes field. By studying the output Stokes intensity and phase distributions, we confirm l mode (OAM) conservation for pure l and p modes, as well as for the superpositions of l and -l for the mode numbers up to l = 4, p = 4. We also found that p index is generally not conserved and its conservation is highly dependent on the relative sizes of the probe and pump beams in the Rb cell. We also identify parameters to improve FWM gain with OAM transfer and propose an analytical method for determining OAM p number.

Another novel for the great woman writer, Hana K. Saba. The novel depicts a family life during and after Iraqi savage invasion to peaceful Kuwait. The novel describes how the baby: Maryam was born in difficult situation and how she survived with her family. We selected this novel as a part of Ihyaa al Turath al Arabi fil Mahjar (Revival of Arab heritage in Diaspora) project supported by the Arab American Encyclopedia originated by the managing editor.The managing editor and publisher is a well known Arab American scholar, poet, and author of more than 200 books, who initiated the project as well as the Arab American Encyclopedia. Dr. Yahya resides in Michigan-USA, and has four children and ten grandchildren.

Arab women writers are increasing in recent years, one of the distinguished authors is Hana Karam Saba Lives in Cyprus. She wrote “hakatha Wolidat Maryam” Novel (Thus, Maryam was Born). A story on Iraqi invasion to Kuwait, and the situation of refugees. Hana wrote short stories and Here “Hiba” (Charity or the Gift). The author shows more talents of great Arab women writers in Diaspora. The Novel reflects the Arab woman situation in the Eastern typical culture in the last half century and is expected to be a serial on TV. The book is part of Ihyaa al Turath al Arabi fil Mahjar (Revival of Arab heritage in Diaspora) project supported by the Arab American Encyclopedia originated by the managing editor, a well known Arab American scholar, poet, and author of more than 200 books, Dr. Yahya resides in Michigan-USA, and has four children and ten grandchildren.
