Discovery of copper chloride cancer in ancient Egyptian polychromic wall paintings and faience: A developing archaeological disaster

We are deeply indebted to the Stiftung Volkswagenwerk for the generous financial support to conduct a detailed research program on ancient Egyptian pigments in time and space. We are grateful to the Egyptian Antiquities Organization specifically to its former Presidents Dr. Ahmed Kadry and Dr. Abdel Halim Nour El Din for their support and for the permission to collect pigment samples from various archaeological sites. During the course of this study we enjoyed the continuous encouragement of Dr. Ahmed Kadry and Dr. Abdel Halim Nour el Din and their deep understanding for the importance of the link between scientific research and Egyptology in solving archaeological problems. We also enjoyed constructive discussions with Dr. Ali Radwan Dean of the Faculty of Archaeology, Cairo University. We are also grateful to the following Directors, officials, and inspectors of the Egyptian Antiquities Organization: Dr. M. Abdel Razeq, Dr. Ali Hassan, Mr. M. Balbush, Dr. M. El Sughair, Dr. M. Saleh, Mr. M. Nasr, Mr. Ismail El Masri and other colleagues at various sites in Egypt. We are also grateful to Dr. Shawki Nakhla, Director of the Conservation Center of the Egyptian Antiquities Organization. This work has benefited from discussions with Dr. E. Martin-Pardey, Mrs. I. Blom, and Dr. A. Eggebrecht. Specifically Dr. E. Martin-Pardey laid the sampling plan for and participated in the field campaign in March 1988 and we enjoyed her egyptological support.

Kernstrakturuntersuchungen mit langsamen Neutronen

Die hier besprochenen Arbeiten wurden dank intensiver Förderung durch viele Menschen und Institutionen durchführbar. Mein besonderer Dank gilt den Professoren H. Maier-Leibnitz, N. Bohr, B. Mottelson und A. Bohr sowie den Mitarbeitern der dänischen Atomenergiekommission, des Instituts Laue Langevin und des Bundesforschungsministeriums. Die Arbeiten wurden durch Kollaborationen mit Wissenschaftlern aus den USA, Belgien und Schweden sehr erleichtert, schon zu einer Zeit, wo Kollaborationen dieser Art völlig unüblich waren. Es ist mir darum ein besonderes Anliegen, meinen Kollegen, besonders Prof. R. Sheline, Prof. T. v. Egidy, Dr. H. Motz, Dr. H. R. Koch, Dr. B. P. Maier, Dr. H. G. Börner, Dr. H. Seyfarth und allen meinen Mitarbeitern von Herzen zu danken.

西辽河流域不同土地利用结构沙土磷解吸特征

采用小型回填式土柱淋溶试验方法,研究了西辽河流域沙土的磷解吸特征.结果表明,西辽河流域沙土的磷解吸特征符合Freundlich和Langmuir解吸等温式;沙土磷的解吸比率(D_r)在0.32～0.98之间,平均值为0.70;最大解吸量(D_m)与饱和吸附量(Г_m)呈极显著正相关;沙土对磷的吸附方式以物理吸附为主,解吸可逆性较强.被吸附的磷在环境中较易发生淋失,仍然存在一定的环境风险.土壤中w(有机质)和w(团聚体)对磷的固持能力有较大影响;不同土地利用结构磷的D_r排序为农田(0.64)=草地(0.64)＜林地(0.67)＜沙荒地(0.91),农田、草地和林地磷淋失的环境风险较小;沙荒地磷淋失的环境风险最大,D_r与土壤中w(粗黏粒),w(黏粒)和w(有机质)呈极显著负相关.
