چکیده
We present high resolution VLT UVES observations of the active K dwarf GJ 117. 6 Li enhancement has been shown for energetic solar events, one chromo-spherically active binary, and several dwarf halo stars. Our analysis reveals the detection of 6 Li on this source with 6 Li 7 Li = 0.030±0.010. We found no significant contribution from other lines, including Ti I, in the Li profile of GJ 117 and a template star of similar spectral type and metallicity. We discuss the possibility for 6 Li production by spallation and find it to be consistent with the activity levels of the object.

The Electrochemical Behavior of Al Alloys in NaCl Solution in the Presence of Pyrazole Derivative
This paper studies the corrosion inhibition of Al-Mg alloy system in 0.5 mol/dm3 NaCl solution in the presence of pyrazole derivative using potentiodynamic polarization and linear polarization method. The inhibition efficiency as a function of concentration and temperature was investigated. From the polarization curves, it can be concluded that the pyrazole derivative be...

متن کاملNew strategy to improve quality control of Montenegro skin test at the production level.
INTRODUCTION The production of the Montenegro antigen for skin test poses difficulties regarding quality control. Here, we propose that certain animal models reproducing a similar immune response to humans may be used in the quality control of Montenegro antigen production. METHODS Fifteen Cavia porcellus (guinea pigs) were immunized with Leishmania amazonensis or Leishmania braziliensis , an...
متن کاملComparative immunohistological analysis of the Montenegro skin test reaction in asymptomatic infection and in acute and chronic cutaneous leishmaniasis.
INTRODUCTION The Montenegro skin test reaction and leishmaniasis lesions share fundamental characteristics of a delayed type hypersensitivity reaction. OBJECTIVES To determine whether the Montenegro skin test reaction (response to leishmanin) might approximate and thereby provide insight into the early inflammatory and immune response to Leishmania infection. MATERIALS AND METHODS We compar...
