Opis:
Most of the heterocorals described up to now from strata older than Famennian are of doubtful affinities. Numerous specimens of the new genus and new species here described were collected during a sedimentological study of the Santa Lucía Formation in La Pola de Gordon (León province, Cantabrian Mountains, NW Spain). Stellaphyllia luciensis gen. et sp. nov. is characterized by cylindrical coralla, with a diameter of less than 2 mm and more than 2 cm long, having stellate to more or less rounded outer profile. Four to six septa, less frequently seven, are cojoined axially by a short oblique septum. The few tabulae present are steeply arched. The microstructure of the septa and interseptal elements shows thin elongate microlamellae parallel to a median plate which is granular in appearance. The new genus dated to the lower Eifelian age could be important in understanding the early phylogeny and origin of the order Heterocorallia.

Opis:
Pochodzenie bagien Parku Narodowego Las Tablas de Daimiel w środkowej Hiszpanii jest związane z wypływem wód podziemnych ze zbiornika regionu zachodniego La Mancha. Wypływ tych wód do bagien zmalał z powodu intensywnej eksploatacji zbiornika. Postępujący zanik bagien skłonił do podjęcia działań zapobiegawczych, w postaci budowy szeregu małych zapór i przepompowywania wody do basenu Las Tablas. Głównym przedsięwzięciem zmierzającym do ratowania bagien było przesyłanie wody z innych basenów, jednak jej część była tracona w obrębie basenu bagiennego, ze względu na infiltrowanie do leżącego niżej zbiornika wód podziemnych. Infiltracja ta stała się ważnym parametrem przy projektowaniu metod utrzymania wody w basenie bagiennym, a także przy zintegrowanym zarządzaniu zasobami wodnymi, związanymi z obszarami bagiennymi. Rzeczywisty rozmiar strat jest trudny do określenia zarówno ze względu na złą jakość istniejących danych, jak i braku określenia różnych ważnych parametrów. Metodyka badań oparta na dziennym bilansie wód w basenie bagiennym pozwala określać te straty i może być stosowana przy zarządzaniu wodami Parku Narodowego.

Opis:
The first case of prostatitis in a ten year old mixed breed dog due to Acanthamoeba genotype T4 is reported. The dog was suffering from kidney dysfunction and was admitted for exploration of its organs by echography. All organs were in normal conditions with the exception of the prostate which showed signs of inflammation. An ultrasound-guided puncture was thus performed for further cytological and microbiological study. When the obtained fluid was observed under the microscope, Acanthamoeba trophozoites were detected in a high number. No other pathogens were isolated. Both culture and PCR were positive for Acanthamoeba genus and the isolate was later identified as genotype T4. Unfortunately at this stage, the dog’s owner decided to reject any kind of treatment or therapy. To the best of our knowledge, this is the first report of prostatitis in a dog due to Acanthamoeba genus.

Opis:
In a martensitic-bainitic microalloyed steel, the effect of hydrogen on fatigue crack growth was studied using rotary bending fatigue tests. The steel was subjected to a rapid thermal cycle to get a microstructure similar to that which would be formed within the coarse-grained heat-affected zone of a weld. Crack growth was monitored as a function of the number of cycles applied during fatigue tests on three types of specimens: 1) those without hydrogen charge, 2) those charged with hydrogen and 3) those charged with hydrogen which was then discharged through low-temperature heat treatment. All types showed persistent slip marks, and cracks propagated along high-shear-stress planes. In the presence of hydrogen, crack growth was affected by microstructural defects caused by the hydrogen charging process, and the persistent slip marks developed in an area closer to the crack tip and crack path. On the contrary, without hydrogen, crack growth occurred perpendicular to the applied force, and the persistent slip marks were fewer in number and further from the crack tip and crack path. This indicates that the plasticity increased (i.e., the damage that occurred in the presence of hydrogen matched the hydrogen-enhanced local plasticity mechanism).

Opis:
We present an alternative method to detect and measure the concentration changes in liquid solutions. The method uses Digital Holographic Interferometry (DHI) and is based on measuring refractive index variations. The first hologram is recorded when a wavefront from light comes across an ordinary cylindrical glass container filled with a liquid solution. The second hologram is recorded after slight changing the liquid’s concentration. Differences in phase obtained from the correlation of the first hologram with the second one provide information about the refractive index variation, which is directly related to the changes in physical properties related to the concentration. The method can be used − with high sensitivity, accuracy, and speed − either to detect adulterations or to measure a slight change of concentration in the order of 0.001 moles which is equivalent to a difference of 0.003 g of sodium chloride in solutions. The method also enables to measure and calculate the phase difference among each pixel of two samples. This makes it possible to generate a global measurement of the phase difference of the entire sensed region.

Opis:
In maize plant breeding aimed at producing a hybrid, it is necessary to characterize the parents and hybrids by their agronomic aspects and grain quality so that the processing industry may offer consumers a quality product and also improve its efficiency. This study evaluated the viscoelastic parameters of masa and the chemical and texture properties of tortillas obtained from parent lines (M-54, M55, and CML-242), two single crosses (M54xM55 and M55xM54), and one hybrid (H-70). The morpho- logy of the maize grains and tortillas was analyzed using scanning electron microscopy. The firmness of masa obtained from CML-242 and H-70 maize was higher than that from the other maize genotypes. M-54 tortillas showed the lowest crude fiber content. Otherwise, tortillas obtained from the M55xM54 hard grain had the lowest fat content and extensibility, while H-70 tortillas showed an intermediate breaking point and extensibility. M-54 and M54xM55 tortillas were softer due to their more swollen starch granules. In contrast, rigid tortillas were obtained from CML-242 and H-70. Grain hardness causes different morphology in starch and tortilla of maize genotypes. However, grain hardness did not influence the characteristics of texture in tortillas.

Opis:
In this paper, explain the preparation of CaTiO3 ceramics synthesized by the solid-state reaction method. Calcium carbonate and titanium dioxide were high energy mixed in stoichiometric amounts, and the obtained mixture was calcined at different temperatures (800, 900, 1000 and 1300ºC) for 2h. The obtained samples were characterized by measurement of particle size, Energy Dispersive X-Ray (EDX) Analysis; differential thermal analysis, X-ray diffraction and SEM images. XRD patterns indicated that CaTiO3 ceramics with the structure of perovskite is obtained from calcined powders at 1,300°C for 2h. SEM images show the formation of a very fine and homogeneous morphology. The measured values of electrical resistivity were within the typical range of insulating materials and approach values corresponding to insulating ceramics.
