Crisis impact on the Romanian economy compared to European Union countries
Get PDFThe second half of 2008 marked, in Romania, the entry into technical recession, and during the following periods of time the economic contractions led to a widespread crisis in almost all sectors. In the first half of 2010, Europe recorded the first increase, more or less timid, meaning leaving the recession, but in Romania we continue to record an economic contraction – in other words, the fourth quarter of crisis. Business analysts and business people consider that this setback was caused by the lowering of the population’s purchasing power and government measures taken or just announced, in the first half of 2010, as well as the bankers’ reluctance to lend to firms.

THE VIRUCID ACTIVITY OF DECONTAMINOL* BIOCIDE
No full textThe purpose of the paper was to investigate the virucide activity of a disinfecting, product based on quaternary amines mixed with glutaraldehyde. The virucide activity was determined against the viruses of the Newcastle disease (ND), aviary influenza (AI), infectious aviary bursitis (IAB) and the infectious aviary bronchitis (IB). Solutions in phosphate buffered saline (PBS), each of 10-4 DIE50/ml of the mentioned viruses were put into contact for 10, 30 and 60 minutes with Decontaminol 0.1% dilutions in sterile hard water4. After the time for contact ended, the mixtures of virus and Decontaminol have been into SPF embryos, with an age of 9 days. Each embryo received 2x10-3 DIE50. The alanto-amniotic fluid was examined for hemaglutinant activities (ND, AI), the embryos for the presence of the specific lesions of IAB, IB. Decontaminol 0.1% dilution had an intense virucide activity (100%) against ND, AI and IAB viruses, which were destroyed after 10 minutes of contact. IAB virus was by the 0.1% Decontaminol solution after 60 minutes of contact.Key words: quaternary amines, glutaraldehyde, virucide activity, aviary viruses (ND, AI, IAB, IB)4 The hard water contains 300 µl/calcium carbonate
ANATOMIC CONSIDERATIONS ON THE MIDDLE EAR IN DOGS
No full textThe middle ear is a bone cavity coated with mucous and full of air. This cavity is implanted inside the temporal bone between the ear drum. Inside the cavity there are four small bones articulated between them in a chain. The lateral wall is membraneous, formed of the tympanum membrane and of a tympanum ring. The median wall is formed of the stone part of the temporal bone and displays three characteristic anatomic formations: promontory, oval window and round window. The promontory looks like an elongated prominence which separates the oval window from the round one. The oval window or the vestibular window is like a slightly ovoid orifice located dorso-medial from the promontory, by which the vestibule communicates with the middle ear. The round window or the cochlear window is a circular orifice located caudo-lateral from the promontory. It is covered by a membrane called the secondary tympanum, which separates the tympanum cavity from the tympanic ramp of the cochlea. In the ventro-lateral side, the tympanum cavity has the tympanum opening. The acoustic bones, the hammer, the anvil, the lenticular bone and the ladder, are articulated between them and form a chain which connects the tympanum and the vestibular window. The bones are driven by two muscles, the tensor muscle and the ladder muscle. The mucus lining the irregularities inside the cavity is in connection with the pharyngeal mucous by means of the auditive tube
