DIVERSE SUPERNOVA SOURCES FOR THE r - PROCESS
We present a simpliÐed analysis using equations for the charge Ñow, which include capture, for the l e production of r-process nuclei in the context of the recent supernova hot bubble model. The role of l e capture in speeding up the charge Ñow, particularly at the closed neutron shells, is studied together with the b Ñow at freezeout and the e†ect of neutrino-induced neutron emission on the ab...
متن کاملABUNDANCES OF ACTINIDES AND SHORT-LIVED NONACTINIDES IN THE INTERSTELLAR MEDIUM: DIVERSE SUPERNOVA SOURCES FOR THE r-PROCESSES
Abundances of Pu, U, U, and Th in the early solar system are about those expected for uniform production over most of galactic history. The inferred abundance of Hf is also compatible with this model. We here associate production of Hf with the same r-process SN sources that produce actinides (SNACS). This requires that r-process nucleosynthesis in SNACS took place rather uniformly over the age...
متن کاملA Search for Supernova-Remnant Masers Toward Unidentified EGRET Sources
Supernova remnants expanding into adjacent molecular clouds are believed to be sites of cosmic ray acceleration and sources of energetic gamma-rays. Under certain environmental conditions, such interactions also give rise to unusual OH masers in which the 1720 MHz satellite line dominates over the more common 1665/7 MHz emission. Motivated by the apparent coincidence of a handful of EGRET sourc...
متن کاملCombining Information from Diverse Sources
Research synthesis plays a central role in the process of scientific discovery, providing a formal methodology for the systematic accumulation and evaluation of scientific evidence. There are many situations in which research synthesis is required because obtaining the required information from an individual trial is not possible or practical. This thesis proposes a general method to synthesize...
متن کاملClonal Relatedness of Enterotoxigenic and Enteropathogenic Escherichia coli Isolates from Diverse Human, Foods and Calf Sources
Background: Foodborne infection caused by EnterotoxigenicEscherichia coli (ETEC) and Enteropathogenic Escherichia coli (EPEC) is one of the major health problems, particularly in the developing countries. Therefore, it is vital to identify the origin of food contamination to plan control strategies efficiently. Method: A tota...
