Ramanand IR-spectra of four compounds of the general composition TlelöMj/",, (I4) \n: formal valence of the M-atom, M = Ag, Au, Pb and (Bio.sTlo.s)] were investigated in order to identify the polyiodide species present. In accordance with structural results comparable amounts of l4 2 and l3~/I~-groups were found for M = Ag, Pb and (Bio.sTlo.s), while in Tl6l6Au2(Li) I3_/I~groups predominate.

Studies of crime at micro places have generally relied on crosssectional data and reported the distributions of crime statistics over short periods of time. In this paper we use official crime data to examine the distribution of crime at street segments in Seattle, Washington, over a I4-year period. W e go beyond prior research in two ways. First, we view crime trends at places over a much long...

The recent recovery of ancient DNA from a growing number of human samples shows that mitochondrial DNA haplogroup I was introduced to Europe after the end of the Last Glacial Maximum. This paper provides a spatio-temporal analysis of the various subhaplogroups of mitochondrial DNA I. The study suggests that haplogroup I diversified into haplogroups I1, I2’3, I4 and I5 at specific regions in Eur...

Violence and aggression in the workplace are problems that most Americans confront on a daily basis. The present study is an exploration of the predisposition to conflict in a work environment in which personality traits responsible for increased sarcasm and increased anger in response to sarcasm are identified. Participants represented two subdepartments within a city general hospital. The Kei...

One effect of stressors such as chronic drug administration is that sequence within the terminal exon of the transcription factor FosB is recognized as intronic and removed by alternative splicing. This results in an open-reading-frame shift that produces a translation stop codon and ultimately a truncated protein, termed DeltaFosB. In vitro splicing assays with control and mutated transcripts ...

Clinical results were evaluated 6 months to I4 years after mitral annuloplasty in 89 operative survivors. Before operation, 13 patients were grade 2, 63 grade 3, and I3 grade 4 (N. Y.H.A. classification). After operation all patients were improved symptomatically. Sixty-one patients were grade I, 27 grade 2, and I patient grade 3. Early clinical deterioration occurred in 5 patients, caused by d...

We present a study of order-disorder phenomena in the series of tetrahedral ordered vacancy compounds Zn1-xMnxGa2Se4 by means of time-of-flight neutron diffraction at high temperature together with dc magnetic susceptibility, Raman spectroscopy, differential thermal analysis and optical absorption experiments. Samples of nominal composition x = 0, 0.24, 0.5, 0.77 and 1 have been studied. An ord...

Raman spectroscopy and angle dispersive X-ray diffraction (XRD) experiments of bismuth selenide (Bi2Se3) have been carried out to pressures of 35.6 and 81.2 GPa, respectively, to explore its pressure-induced phase transformation. The experiments indicate that a progressive structural evolution occurs from an ambient rhombohedra phase (Space group (SG): R-3m) to monoclinic phase (SG: C2/m) and e...

Bernstein (1967) hypothesized that preparation of the periphery was crucial for correct responses to motor output. To test this hypothesis in a behaving animal, we examined the roles of two identified motor neurons, B7 and B8, which contribute to feeding behavior in the marine mollusk Aplysia californica. Neuron B7 innervates a hinge muscle and has no overt behavioral effect during smaller-ampl...
