A new rose hybrid was found in Slovakia, Malé Karpaty Mts, close to the Plavecky Peter on the hill Ježovka. This rose taxon called Rosa × braunii was described by Jenő B. Keller from the Bruck an der Leitha (Austro-Hungarian Empire) in 1882. It is a hybrid of R. tomentosa Sm. and R. spinosissima L. Its morphology, diagnostic features, chorology and conservational status are discussed. Legal protection of this taxon is highly recommended, because this is its second population in the world, the only currently known locality, and it is a unique taxon, not an introgressive hybrid.
Although porcine adenoviruses (PAdV) are present in the swine populations worldwide, they usually do not cause any disease, or the infection is only manifested in a mild diarrhoea or respiratory signs. The importance of adenoviruses, however, is constantly growing as there is a possibility of developing them into viral vector vaccines against more significant swine pathogens. A short summary of the well-established facts of porcine adenoviruses is given and recent developments of the genetic analysis of these viruses are discussed in detail. The possibilities of vector development and examples of vector vaccines already reported in the literature are mentioned.
Dynamic mechanical thermal analysis and isothermal thermogravimetry yield useful information on the temperature dependence
of the mechanical properties and thermal stability of silicone rubbers.
In the thermal mechanical relaxation spectra, only one characteristic phenomenon may be observed.
Isothermal thermogravimetry reveals that the thermal degradation is a first-order reaction. The experimental results provide
a possibility for the calculation of overall (apparent) reaction rate constants characteristic of the thermal decomposition
process, and for the calculation of half-time values.
The Kiskunhalas-NE (KIHA-NE) fractured hydrocarbon reservoir is part of the structurally rather complex crystalline basement of the Great Hungarian Plain. In the course of petrologic and thermometric examinations various rock types of the investigated area have been classified and characterized. There are four basic lithological units in the area. In the lowest structural position orthogneiss is common, which according to its petrographic features is assumed to be identical to the orthogneiss body of the adjacent Jánoshalma (JH) basement high (metamorphic peak temperature T < 580 °C according to Zachar and M. Tóth 2004). The next rock unit upward is the highly mylonitized variety of the orthogneiss with textural features suggesting deformation in an extensional stress regime. In the higher section of the mylonite zone graphitic gneiss mylonite is characteristic, with a peak metamorphic T of 410±45 °C. The lithology in the shallowest position of the area is a graphitic carbonate phyllite, with a T of 375 ± 15 °C. Estimation of the deformation temperature for both mylonitic rocks results in approximately Tdef ∼ 455 °C. All data together suggest that between the top (graphitic carbonate phyllite) and the bottom (orthogneiss) of the ideal rock column there is about 200 °C peak metamorphic temperature deviation. The two extreme metamorphic blocks probably became juxtaposed along an extensional fault zone in the basement at approximately 15 km depth.
The combination of lactofermentation and enzyme-treatment (Rohament-PL as endo-polygalacturonase and the mixture of Rohament-PL and Rohalase 7069 as cellulase) of sliced carrot and orange juice resulted in a homogeneous product, with pleasant organoleptic features, after 18 h fermentation period. Two ways of inoculation were applied with Lactobacillus plantarum. The addition of Rohament-PL, even at 150 mg kg-1 concentration, simultaneous inoculation with Lactobacillusplantarum (circumstances: 28 °C, 80 r.p.m. shaking) promoted the growth of lactobacilli. By 42 h fermentation time LAB count increased up to 3.2-4.8´109 cm-3. Furthermore the surface colour of the samples was more intensive (higher L-, a- and b-values) than without Lactobacillus plantarum inoculation. The application of Rohament-PL (50-100 mg kg-1) resulted in a homogeneous carrot puree, the combination of Rohament-PL (150 mg kg-1) and Rohalase 7069 (150 mg kg-1) in the process gave a more fluid product, as proved by the lower specific viscosity values.
The adsorption kinetics of strontium ion was studied on seven natural clay samples with radioactive tracer method. The kinetic
curves were determined and the kinetic data were evaluated by forms of first-rate kinetic equations with different terms,
generally used for adsorption of ions of low concentration. The adsorption process was reduced to two steps. Film diffusion
and participle diffusion were found in the case of five samples. Gel diffusion, film diffusion and participle diffusion were
found in the case of the other two samples. The presence of significant amount of cristobalite can explain the gel phase in
these two samples. The rate coefficients of steps were calculated from the kinetic curves.
This study aimed to examine the effectiveness of CO2 laser-assisted sclerectomy surgery (CLASS) in eyes with primary open-angle glaucoma (POAG) showing progression in spite of maximal local antiglaucomatous therapy.
Materials and methods
Patients with progressive POAG received CLASS treatment. We performed CLASS on 15 eyes (eight males and seven females). The primary endpoint was the change in the intraocular pressure (IOP), and additionally best spectacle-corrected visual acuity (BSCVA), C/D ratio (cup-to-disc), as well as use of antiglaucomatous drops were also investigated. Following the preoperative assessment, measurements were performed at 6-month follow-up.
The average preoperative IOP was 26.13 ± 6.79 mmHg that dropped to 9.57 ± 4.09 mmHg at 1 day. IOP was stable at 1 month, 3 months, and 6 months. The BSCVA decreased to the 1-day and 1-week follow-up but returned to its original value to the 1-month check-up. Preoperatively, all patients were on maximal antiglaucoma drop therapy, after CLASS none of the patients needed antiglaucomatous treatment at 1 month. However, at 3 months, one of them needed antiglaucoma drops. C/D ratio showed non-significant changes.
CLASS procedure was found to be effective in decreasing IOP in POAG patients whose IOP was not compensated with maximal antiglaucomatous local therapy; patients needed significantly less local therapy following the CO2 laser surgery.
