Józef Wyrobek (1850-1924). A contribution to the biography based on editing his letters Kazimierz Bartoszewicz (1850-1924) is regarded be first historian of Dębica, a former Galician town, where he was secondary school teacher for 20 years. So far no has been created. His two (1852-1930), well-known author, bookseller and publisher, preserved in State Archive, have become pretext having look at...

Examination of Coccinellidae material recently collected from Napo Province in Ecuador revealed 38 species ladybird beetles, which six are new: Chnoodes yanayacu sp. nov., Cyrea mcclarini Eupalea borowieci Exoplectra misahualli Hyperaspis rutai Toxotoma gonzalezi nov. Seven recorded for the first time Ecuador: noticollis (Mulsant, 1850), formosa Mulsant, 1850, Epilachna transverselineata (Mader...

A new sample of 175,000 individuals is analyzed to assess the effect of socioeconomic status on mortality in the nineteenth century U.S. The sample consists of decedents from the mortality schedules and survivors from the population schedules of the 1850 and 1860 federal censuses. In 1850, for males age 20-44 in fifty rural counties, occupation was a poor predictor of all-cause mortality, thoug...

Global surface temperature records (e.g. HadCRUT4) since 1850 are characterized by climatic oscillations synchronous with specific solar, planetary and lunar harmonics superimposed on a background warming modulation. The latter is related to a long millennial solar oscillation and to changes in the chemical composition of the atmosphere (e.g. aerosol and greenhouse gases). However, current gene...

The intentional use of mercury (Hg) in products and processes ("commercial Hg") has contributed a large and previously unquantified anthropogenic source of Hg to the global environment over the industrial era, with major implications for Hg accumulation in environmental reservoirs. We present a global inventory of commercial Hg uses and releases to the atmosphere, water, soil, and landfills fro...

Despite recognizing their importance, hospital historians have traditionally been less interested in the administrative and financial aspects of institutions under study, although paradoxically this documentation has survived much better than clinical records. We tend easily to forget that most hospitals periodically teetered on the brink of insolvency even though many had been initially launch...

The Accellera Property Specification Language (PSL) was developed to provide a standard assertion language for use in both simulation and formal verification tools and in the context of a variety of hardware description languages. After four years of development in Accellera, PSL has now been transferred to the IEEE for standardization. This paper presents an overview of the IEEE 1850 PSL activ...

Using longer wavelength laser drivers for high harmonic generation is desirable because the highest extreme ultraviolet frequency scales as the square of the wavelength. Recent numerical studies predict that high harmonic efficiency falls dramatically with increasing wavelength, with a very unfavorable lambda(-(5-6)) scaling. We performed an experimental study of the high harmonic yield over a ...
