Horizons: nuclear astrophysics in the 2020s and beyond
Nuclear astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the chemical elements. This white paper summarizes progress and status of the field, the new open questions that have emerged, and the tremendous scientific opportunities that have opened up with major advances in capabilities across an ever growing number of disciplines and subfields that need to be integrated. We take a holistic view of the field discussing the unique challenges and opportunities in nuclear astrophysics in regards to science, diversity, education, and the interdisciplinarity and breadth of the field. Clearly nuclear astrophysics is a dynamic field with a bright future that is entering a new era of discovery opportunities

Horizons: Nuclear Astrophysics in the 2020s and Beyond
Nuclear Astrophysics is a field at the intersection of nuclear physics and
astrophysics, which seeks to understand the nuclear engines of astronomical
objects and the origin of the chemical elements. This white paper summarizes
progress and status of the field, the new open questions that have emerged, and
the tremendous scientific opportunities that have opened up with major advances
in capabilities across an ever growing number of disciplines and subfields that
need to be integrated. We take a holistic view of the field discussing the
unique challenges and opportunities in nuclear astrophysics in regards to
science, diversity, education, and the interdisciplinarity and breadth of the
field. Clearly nuclear astrophysics is a dynamic field with a bright future
that is entering a new era of discovery opportunities.Comment: 96 pages. Submitted to Journal of Physics
Decolorization of mono-azo dyes in aqueous medium by ozonation process
Ozonation of C.I. 18735 Mordant Red 19 (5-hydroxy-3-methyl-1-phenyl-4[5- chloro-2-hydroxy-3-sulfophenyl)-azo]-pyrazole, sodium salt), HFANS (1,2-hydroxo phenyl azo,8-amino naphthalene,3,6-disulfonic acid mono sodium salt) and their metal complexes with chromium, C.I. 18736 Acid Red 180 and HFANS-Cr, has been carried out in aqueous medium. Various parameters, such as ozone consumption and colour elimination percentage, were investigated. The biodegradability of these dyes was determined and supported with the standard method for methylene blue active substances. The metal complexes of the mono-azo dyes consumed more ozone than that without metal. Finally, the differences between ozonation of azo dyes and their metal complexes were outlined, based on the experimental results obtained
Difficulties Experienced During Preparation And Administration Of Oral Drugs
AIM: It was aimed to determine the difficulties experienced by pediatric nurses working in the wards of a university hospital during preparation and administration of drugs and to determine solution recommendations. MATERIAL AND METHODS: One hundred and eight nurses who accepted to participate in the study constituted the sample of the study. Open-ended questions were asked in order to obtain detailed information about the attitudes and views of the participants and face to face interview was used. The problems experienced during preparation and administration of drugs were collected using the data collection form prepared by the investigators. Institution approval, ethics committee approval (HEK12/193) and written informed consent from the nurses who wished to participate in the study were obtained to conduct the study. The data obtained were expressed as figures and percentages. RESULTS: The most commonly reported problems in preparation of drugs included incomplete dissolution of tablets or non-homogeneous distribution in fluids (54.6%) and difficulty in breaking tablets in appropriate doses (45.3%). The most commonly reported problem experienced during administration of drugs was rejection of drugs which tasted bad by babies/children or spitting out the drug (75.9%). In our study, the nurses also mentioned the problems related with drug administration equipment. These problems included fear of injectors (25.9%), escape of the drugs into the respiratory way (15.7%) and lack of appropriate equipment for administering the drugs (7.4%). CONCLUSIONS: In our study, it was found that all nurses experienced difficulty in preparing and administering drugs. The problems experienced by the nurses and solution recommendations for these problems were reported to the hospital administration
