¹⁸⁶Ir gamma transitions are studied via the reaction
Hf (¹⁴N, xn) Au at ¹⁴N beam energy 130 MeV. The beta decay
chain of Au is Au + Pt + Ir + Os. Singles and coincidence
data are from measurements by Ge gamma-ray detectors.
Conversion electrons are measured by Si(Li) detector....
A new general method is developed for the optimization of
HPLC ternary or pseudo-quaternary mobile phases which are
represented by the trilinear coordinate system. This method can
predict the global optimum of the mobile phase composition. The
global optimum composition along each edge of the triangle and
the corresponding selectivity...
The Va nationality, despite its small population compared
to other nationalities in China, has preserved most of its
traditions largely due to limits placed by historical
circumstances and geographical isolation. To non-Chinese
anthropologists, the Va people still remain unknown, as there
is little or no information about them in English...
This study uses an anthropological perspective
to discuss the cultural differences between Chinese
and Americans in business contexts. Through an
analysis of case studies related by businesspersons
involved in Sino-US trade, and by an analysis of
literature on the subject, it describes how cultural
differences contribute to the problems and...
Gender relations as well as the social situation of Manchu women have long been ignored in studies of the cultural evolution of the Manchu. By setting the discussion of Manchu women in the context of cultural adaptation, this study reintroduces gender and women's problems into the research on the Manchu...
Culture, thought worldview and language have been
discussed for a long time in different fields from various
perspectives. However, the basis of this study is the view
of language as both the product and producer of people just
as people are the producer and product of language. Each
language requires...
The DNA-binding domains of E. coli uracil-DNA glycosylase (Ung) and human replication protein A (hRPA) were studied using a general protocol developed in our laboratory for probing protein-DNA interactions. The procedure involves purification and mass spectrometric analysis of the nucleopeptide-products of a tryptically digested UV-crosslinked protein-nucleic acid complex. In the...
Multi-stage delta-sigma (ΔΣ) architectures, commonly known as MASH, are the preferred choice for analog-to-digital converters (ADCs) used in broadband communication applications, where high-resolution (above 14 bits) and high-bandwidth (several MHz) performances are required. Current state-of-the-art designs are capable of as much as 5-MS/s output data rates with 90-dB SNR. However,...
