We report a method for determining the specific heat capacity in solids by means of the photoacoustic (PA) technique in a heat transmission configuration. This method involves a modulation frequency range where the samples are thermally thin and a liquid (i.e., distilled water) as a reference sample. It is free of PA cell parameters and was tested in some metals and semiconductors. The results agree very well with literature reported values for these samples.

We foundKlebsiella ozaenaein only six women of 30 patients (20 females, ten males) suffering from atrophic rhinitis. These isolates were confirmed three times at intervals of 15 days. In the remaining 24 patients a wide variety of microorganisms were isolated,Proteus mirabilishaving the highest incidence.

Its persistence in wild boar (WB), longer than in domestic pig farms, and the knowledge gaps in ASF epidemiology hinder ASF virus (ASFV) eradication. Even in areas where disease is effectively controlled and ASFV is no longer detected, declaring eradication is difficult as seropositive WBs may still be detected. S u i f o r m S o u n d i n g s 1 9 (2) 1 0 7 were convinced of the potential of vaccination in controlling ASF. [Extracted from the article]
