Abstract In the present work, form factors of $$B_{(s)}$$ B ( s ) to light P-wave tensor mesons ( $$a_2(1320)$$ a 2 1320 , $$K^*_2(1430)$$ K...
This paper explores an aspect of the legacy Declaration Arbroath and expands upon earlier research into tensions surrounding commemorations in 1814 battle Bannockburn. It considers evidence for connections between those radical artisans their leaders who attempted to rouse popular insurrection 1820, Scotland’s so-called ‘radical war’, Bruce’s now-celebrated missive papacy 6 April 1320, five cen...

The basic element of the design a power module is metallized ceramic substrate. In this work, formation metallization coatings by method thermal transfer pastes (Mo-Mn-Si + binder) for alumina and aluminum nitride ceramics was carried out. fixing coating on substrate performed firing at temperature 1320 °C. subsequent deposition copper layer out cold gas-dynamic spraying (CGDS) followed anneali...
geographical location and climatic condition in the northern coast of persian gulf provided a suitable condition for the spread of epidemic diseases and their continuity. in qajar period, increased relations with india, mesopotamia and lack of health facilities caused the death of many residents in these areas. at the beginning of reza shah’s reign and the government’s attitude towards moderniz...
Optical cavity enhancement is a highly desirable process to make sensitive direct-absorption spectroscopic measurements of unknown substances, such as explosives, illicit material, or other species of interest. This paper reports advancements in the development of real-time cavity ringdown spectroscopy over a wide-bandwidth, with the aim to make headspace measurements of molecules at trace leve...
sance writings, from scholars like Hostiensis (ca.1200–71), Oresme (1320–82) and Copernicus (1473–1543), and from mint officials like Henri Poullain (1612). As we have just seen, Aristophanes, in the 5th century B.C.E., had already anticipated the mechanism. And it was the British economist, Stanley Jevons, who originated the expression “bad money drives out good money” in his 1875 book, Money ...
High power semiconductor lasers with wavelengths in the eye-safer region have application to a variety of defense, medical and industrial applications. We report on the reliability of high power multimode and single mode InGaAsP/InP diode lasers with wavelengths in the range 1320 to 1550 nm in a variety of configurations, including single-chip, conduction-cooled arrays, arrays incorporating int...
From the Tait equation an equation of state containing five adjustable parameters was developed which fits experimental density data of molten potassium chloride to 1320 K and 6 kbar with a standard deviation of 0.04%. The thermal expansion coefficient, isothermal compressibility, internal pressure, and molar heat capacities at constant pressure and constant volume were calculated as functions ...
Franck-Condon effects associated with intervalence excitation of the Creutz-Taube ion (a prototypical delocalized mixed-valency system) have been evaluated via a time-dependent analysis of resonance Raman scattering intensities and the intervalence absorption lineshape. Quantitative studies in the extended near infrared (1320 nm excitation) revealed that at least eight, and possibly nine, vibra...
