Abstract. Re-investigation of the type material beraunite from Hrbek Mine, Svatá Dobrotivá, Czech Republic, proved identity and eleonorite. Based on this study, mineral eleonorite was discredited, ideal formula redefined Fe2+Fe53+(PO4)4(OH)5 ⋅ 6H2O to Fe63+(PO4)4O(OH)4 6H2O. Beraunite Mine usually forms prismatic crystals flattened {100}; elongated along b axis, striated {100} || b, up 0.2 × 0....

the main objective of the present study is to elaborate the contrasts between males and females in their use of different strategies of complaint in english and persian and ascertain the degree to which independent variables like gender and language affect the application of these strategies during informal communication. furthermore, it offers comparable corpora which provide a good basis for ...

introduction: e-learning is one of the most important and common paradigms of ict in educational areas. it may help promote creativity, an important, basic and effective component of human life. the aim of this paper is to study the effect of e-learning on students' creativity at meshkinshahr payame noor university in the 2012-2013 academic year.materials and methods: a quasi experimental ...

Abstract. Dissolution dynamic nuclear polarization is used to prepare spin polarizations approaching unity. At present, 1H quantification in the solid state remains fastidious due requirement of measuring thermal equilibrium signals. Line shape polarimetry solid-state magnetic resonance spectra determine several useful properties regarding system under investigation. In case highly polarized sp...

Abstract. On 4 March 2021, two tsunamigenic earthquakes (Mw 7.4 and Mw 8.1) occurred successively within 2 h in the Kermadec Islands, offshore New Zealand. We examined sea level records at tide gauges located ?100 to ?2000 km from epicenters, conducted Fourier wavelet analyses as well numerical modeling of both tsunamis. indicated that energy first tsunami is mainly distributed over period rang...

Abstract. We developed thermal dissociation cavity-enhanced absorption spectroscopy (TD-CEAS) for the in situ measurement of NO2, total peroxy nitrates (PNs, RO2NO2), and alkyl (ANs, RONO2) atmosphere. PNs ANs were thermally converted to NO2 at corresponding pyrolytic temperatures detected by CEAS 435–455 nm. The instrument sampled sequentially from three channels ambient temperature, 453 653 K...

The metabolism of adenosine 3',5'-monophosphate (cyclic AMP) was studied in specific pathogen-free mice exposed to neonatal infection with mouse enterovirus or to malnutrition during early life. Metabolic activity was determined by measuring the turnover of cyclic AMP-8-(14)C to respiratory (14)CO(2), its incorporation into various organs and plasma, and the binding activity of synaptosome for ...

When whole urinary bladders of the toad were incubated with adenosine 3',5'-monophosphate-(3)H (cyclic AMP-(3)H) > 95% of the radioactivity could be extracted from the tissue with trichloroacetic acid (TCA). The TCA-soluble radioactivity was separable by cation-exchange (Dowex-50) chromatography into residual cyclic AMP-(3)H, 5'-AMP-(3)H, adenosine diphosphate (ADP)-(3)H and inosine-(3)H. Thus,...
