We obtain abundances of α, iron peak and neutron capture (n-capture) process elements in four Ba stars HD26886, HD27271, HD50082 and HD98839 based on high resolution, high signal-to-noise spectra. We find that all of these Ba stars are disk stars. Their α and iron peak elements are similar to the solar abundances. The n-capture process elements are overabundant relative to the Sun. In particula...

We present the €rst baŠery-free cellphone design that consumes only a few micro-waŠs of power. Our design can sense speech, actuate the earphones, and switch between uplink and downlink communications, all in real time. Our system optimizes transmission and reception of speech while simultaneously harvesting power which enables the baŠery-free cellphone to operate continuously. Œe baŠery-free d...

Business intelligence (BI) combined with business analytics (BA) is an increasingly prominent strategic objective for many organizations. As a pedagogical subject, BI/BA is still in its infancy, and, in order for this to mature, we need to develop an undergraduate model BI/BA curriculum. BI/BA as an academic domain is emerging as a hybrid of disciplines, including information systems, statistic...

by immunizing mice with killed whole bacterial cells of brucella abortus s (99), a panel of six hybridomas producing monoclonal antibodies (mab) specific for the surface antigens of this bacterium were produced. elisa was used to screen the hybridoma supernatants. immunoblots of the cell extract indicated that three mab were specific for s-lps (ba-1, ba-2, ba-3) and three others were reactive w...

BACKGROUND AND PURPOSE Both Doppler sonography (DS) and spiral CT angiography (CTA) are noninvasive vascular assessment tools with a high potential for application in acute cerebral ischemia. The usefulness of CTA for vascular diagnosis in acute basilar artery (BA) ischemia has not yet been studied. METHODS We prospectively studied 19 patients (mean+/-SD age, 58+/-11 years) with clinically su...

The simultaneous detection of Pb and Pb ions has been made by multiple-ion counting ICP-mass spectrometry using two Daly detectors (MC-ICPMS). To evaluate the long-term gain stability of the detectors, Ba/Ba and Ba/Ba ratios have been measured by a combination of Daly and Faraday detectors (Ba(D)/Ba(F)) and an electron multiplier and Faraday detectors (Ba(EM)/Ba(F)). The measured Ba(EM)/Ba(F) r...

We conducted an event-related, functional MRI investigation of 12 male's and 12 female's reasoning about conditional deontic rules, rules regulating people's behavior. We employed two different types of rules: social contracts and nonsocial, precautionary rules. Although the rules and the demands of the task were matched in terms of their logical structure, reasoning about social contracts and ...

Few morphological differences have been identified so far that distinguish the human brain from the brains of our closest relatives, the apes. Comparative analyses of the spatial organization of cortical neurons, including minicolumns, can aid our understanding of the functionally relevant aspects of microcircuitry. We measured horizontal spacing distance and gray-level ratio in layer III of 4 ...

Barium/Calcium profiles of bivalve shells are characterized by flat background signals periodically interrupted with sharp peaks, with the background signals correlated with water Ba/Ca. To test if the peaks are an environmental signal related to productivity, we analyzed high resolution Ba/Ca profiles in bivalve shells that grew adjacent to one another. Two aragonitic Saxidomus giganteus show ...

Influence of bronchial asthma (BA) severity on physical development in children patients was evaluated in comparison with healthy population. Materials and Methods. 1042 children and adolescents (768 boys) with atopic BA were evaluated. All children underwent standard examination in a clinical setting, including anthropometry. The control group included 875 healthy children of a comparable age ...
