Impact of H in H2O thermal scattering data on criticality calculation: uncertainty and adjustment

open access: yesEPJ Nuclear Sciences & Technologies, 2022
In this paper, the impact of the thermal scattering data for H in H20 is estimated on criticality benchmarks, based on the variations of the CAB model parameters. The Total Monte Carlo method for uncertainty propagation is applied for 63 keff criticality

A new look at NICMOS transmission spectroscopy of HD189733, GJ-436 and XO-1: no conclusive evidence for molecular features [PDF]

open access: yes, 2010
We present a re-analysis of archival HST/NICMOS transmission spectroscopy of three exoplanet systems; HD 189733, GJ-436 and XO-1. Detections of several molecules, including H20, CH4 and CO2, have been claimed for HD 189733 and XO-1, but similarly sized features are attributed to systematic noise for GJ-436. The data consist of time-series grism spectra

Cigarette taxation and consumption in The Czech Republic. Have these factors influenced tax revenue?

open access: yesFinancial Internet Quarterly
The article evaluates the development of the tax burden on cigarettes in the Czech Republic from 1993 to the end of 2023. Tax burden is represented by effective tax rate. The research results show that the tax burden on these products is still increasing.

Degree of Phosphorous Saturation in Intensively Cultivated Soils in Sri Lanka

open access: yesTropical Agricultural Research, 2011
The loss of Phosphorous (P) from intensively cultivated soil is one of the major causes of reducing water quality. The Degree of Phosphorous Saturation (DPS) which relates the extractable P of a soil to its P adsorption capacity is a good indicator of ...

The CHESS survey of the L1157-B1 bow-shock: high and low excitation water vapor [PDF]

open access: yes, 2013
Molecular outflows powered by young protostars strongly affect the kinematics and chemistry of the natal molecular cloud through strong shocks resulting in substantial modifications of the abundance of several species. As part of the "Chemical Herschel Surveys of Star forming regions" guaranteed time key program, we aim at investigating the physical ...

The generation of latent-ion-transport capacity [PDF]

open access: yes, 1959
Of the various hypotheses designed to explain the movement of ions from the environment into the plant cell, the most attractive suggests that ions traverse cell membranes in combination with an endogenously produced carrier substance.(1,2) The ...

Saturn's south polar cloud composition and structure inferred from 2006 Cassini/VIMS spectra and ISS images [PDF]

open access: yes, 2019
We used 0.85 - 5.1 micron 2006 observations by Cassini's Visual and Infrared Mapping Spectrometer (VIMS) to constrain the unusual vertical structure and compositions of cloud layers in Saturn's south polar region, the site of a powerful vortex circulation, shadow-casting cloud bands, and spectral evidence of ammonia ice clouds without the lightning ...
