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 the silicon ribbon on a sacrificial template process silicon is deposited on both sides of a carbon ribbon, thus forming a Si/carbon/Si trilayer. The fast cooling of the ribbon in large temperature gradients generates stresses that are detrimental to both the electrical performance and the mechanical behaviour of the wafers. The assessment of the stresses is crucial for the setting-up of thermal treatments allowing for the stress relaxation of the wafers, prior to the cell fabrication. We present an analysis of the stress in the as-grown trilayer by a simulation of the thermomechanical behaviour of the cooling ribbon. Experimental measurements of the stress in as-grown and annealed trilayers are also presented. The results permit to establish the conditions for optimized growth and annealing.

Opis:
Shells of Bouchardia rosea (Brachiopoda, Rhynchonelliformea) are abundant in Late Holocene death assemblages of the Ubatuba Bight, Brazil, SW Atlantic. This genus is also known from multiple localities in the Cenozoic fossil record of South America. A total of 1211 valves of B. rosea, 2086 shells of sympatric bivalve mollusks (14 nearshore localities ranging in depth from 0 to 30 m), 80 shells of Bouchardia zitteli, San Julián Formation, Paleogene, Argentina, and 135 shells of Bouchardia transplatina, Camacho Formation, Neogene, Uruguay were examined for bioerosion traces. All examined bouchardiid shells represent shallow−water, subtropical marine settings. Out of 1211 brachiopod shells of B. rosea, 1201 represent dead individuals. A total of 149 dead specimens displayed polychaete traces (Caulostrepsis). Live polychaetes were found inside Caulostrepsis borings in 10 life−collected brachiopods, indicating a syn−vivo interaction (Caulostrepsis traces in dead shells of B. rosea were always empty). The long and coiled peristomial palps, large chaetae on both sides of the 5th segment, and flanged pygidium found in the polychaetes are characteristic of the polychaete genus Polydora (Spionidae). The fact that 100% of the Caulostrepsis found in living brachiopods were still inhabited by the trace−making spionids, whereas none was found in dead hosts, implies active biotic interaction between the two living organisms rather than colonization of dead brachiopod shells. The absence of blisters, the lack of valve/site stereotypy, and the fact that tubes open only externally are all suggestive of a commensal relationship. These data document a new host group (bouchardiid rhynchonelliform brachiopods) with which spionids can interact (interestingly, spionid−infested sympatric bivalves have not been found in the study area despite extensive sampling). The syn−vivo interaction indicates that substantial bioerosion may occur when the host is alive. Thus, the presence of such bioerosion traces on fossil shells need not imply a prolonged post−mortem exposure of shells on the sea floor. Also, none of the Paleogene and Neogene Bouchardia species included any ichnological evidence for spionid infestation. This indicates that the Spionidae/ Bouchardia association may be geologically young, although the lack of older records may also reflect limited sampling and/or taphonomic biases.

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.

We approach this answer through a wider investigation (Martinez, 2010) conducted in two phases: an initial qualitative one using an interview as a tool for obtaining information, and a second one more quantitative with an electronic questionnaire. The results show the importance that tutors attribute to “being available for students”, “integration into the center” and “providing contextual knowledge and access to documentation of the institution”.

Opis:
This paper presents an approach to optimize a Convolutional Neural Network using the Fuzzy Gravitational Search Algorithm. The optimized parameters are the number of images per block that are used in the training phase, the number of filters and the filter size of the convolutional layer. The reason for optimizing these parameters is because they have a great impact on performance of the Convolutional Neural Networks. The neural network model presented in this work can be applied for any image recognition or classification applications; nevertheless, in this paper, the experiments are performed in the ORL and Cropped Yale databases. The results are compared with other neural networks, such as modular and monolithic neural networks. In addition, the experiments were performed manually, and the results were obtained (when the neural network is not optimized), and comparison was made with the optimized results to validate the advantage of using the Fuzzy Gravitational Search Algorithm.

Opis:
An integrated biostratigraphic approach, based on ammonites, calcareous nannofossils, dinoflagellates, combined with sedimentology, carbon-isotope and physical stratigraphy, is proposed for the Subalpine Basin (Thuoux and Saint-Pierre d’Argençon sections). Within the expanded marl deposits of the Terres Noires Fm., the Callovian-Oxfordian boundary is particularly well defined by ammonite taxa from different families (i.e. Cardioceratidae, Oppeliidae, Aspidoceratidae and Perisphinctidae), calcareous nannoplankton (first occurrence of large-sized Stephanolithion bigotii) and dinoflagellate cysts (first occurrence of Wanaea fimbriata). This precise biostratigraphy and diversity of ammonites permit long-range correlations with Boreal and Pacific domains. The exceptional outcrop conditions and continuous sedimentation allow high-resolution chemostratigraphy and cyclostratigraphy to be used. Variations of the δ13C record (1.5‰ increase during the Lamberti Zone), consistent with data from other sections of the Subalpine Basin and with the Paris Basin, provide additional markers to characterise the Callovian-Oxfordian boundary. Promising results from cyclostratigraphy should serve to constrain the duration of biostratigraphic units and thus improve the Late Jurassic Geologic Time Scale. Comparisons are made with the two other candidates for an Oxfordian GSSP, Redcliff Point (UK) and Dubki (Russian Platform). Finally, the advantages of the Subalpine Basin sections support the proposal of Thuoux as a suitable GSSP candidate for the base of the Oxfordian Stage

Opis:
In order to improve the physiology of plants, this research evaluated the effect of high-intensity LED light (red, blue and green) on the following variables: germination (PG), hypocotyl length (HL), fresh (FW) and dry (DW) weight, in three types of lettuce seed (White Boston, Romana and Black Simpson). Exposure times with colour light were 12, 6 and 3h, with a complement of time for treatments with 6 and 3h of white LED light. We used a completely randomised design with four replications of 30 seeds. Treatments with green and red light to 12h had increases above 90% in HL against the control for the three varieties. The blue light treatment (3h) increased 23% in FW White Boston variety and the red light (3h) increased 14% the DW variable in Roman variety, compared to the control. In this study, treatments with colour light presented results above the control; however, a treatment with a single type of light is not optimal to improve plant physiology. The physiological responses evaluated showed variation related to the genotype of seed and to the time of exposure to high-intensity LED light, so this type of light is a viable option for improving the physiology of plants.
W celu uzyskania poprawy fizjologii roślin, w badaniach dokonano oceny wpływu światła LED wysokiej intensywności (czerwone, niebieskie i zielone) na następujące zmienne: kiełkowanie (PG), długość hipokotylu (HL), świeżej (FW) i suchej (DW) masy nasion trzech odmian sałaty (White Boston, Romana i Black Simpson). Czasy naświetlania światłem barwnym wynosiły 12, 6 and 3 h, z uzupełniającym doświetlaniem wariantów z czasami 6 i 3 h białym światłem LED. Zastosowano kompletnie zrandomizowany układ doświadczenia, w czterech powtórzeniach po 30 nasion. Warianty ze światłem zielonym i czerwonym oraz czasami naświetlania do 12 h wykazały ponad 90% wzrost HL w stosunku do kontroli dla trzech odmian. W wariancie ze światłem niebieskim (3 h) uzyskano 23% wzrost parametru FW u odmiany White Boston, a w wariancie ze światłem czerwonym (3 h) 14% wzrost zmiennej DW u odmiany Roman, w porównaniu do kontroli. W badaniach zastosowanie naświetlania światłem barwnym dało lepsze wyniki niż w przypadku kontroli, jednak naświetlanie jednym rodzajem światła nie jest optymalne dla uzyskania poprawy fizjologii roślin. Oceniane reakcje fizjologiczne zmieniały się w zależności od genotypu nasion i czasu naświetlania światłem LED wysokiej intensywności, tak więc zastosowanie tego typu światła stanowi możliwą opcję w poprawie fizjologii roślin.

Opis:
The effect of UV-C light as a means of control of natural mycobiota of grains of maize (Zea mays L.) hybrids “San Juan” and ”H-159” (productive cycle, 2009) was investigated. UV-C lamps of 15 W were used and the exposure times applied were 0, 5, 10, 15, 20, 25 and 30 min. The experiment was established in the randomised complete block design with eight and four replicates. The unit pilot was 50 grains. For the determination of mycobiota the agar plate test was used, after disinfection of the grains with sodium hypochlorite diluted to 3% for 1 min. Differences (P ≤ 0.001, P ≤ 0.05) between treatments were found, the best treatments being those of 30 and 10 min, observing reductions of 42.85 and 52.05% in the number of grains infected with Fusarium spp. with respect to control for “San Juan” and “H-159”, respectively. For Fusarium monoliforme it was found that in 30 min there was a reduction of 53.74% for the hybrid “San Juan”, while for H-159 a reduction of 61.7% in 10 minutes was observed. These results show that UV-C radiation may be useful for application as a germicide in future experiments on a wide variety of grains.
Badano wykorzystanie promieniowania UV-C jako metody zwalczania naturalnych mikobiot ziarna hybryd kukurydzy (Zea mays L.) “San Juan” i ”H-159” (cykl produkcyjny, 2009). Zastosowano lampy UV-C o mocy 15 W, a czasy ekspozycji wynosiły 0, 5, 10, 15, 20, 25 oraz 30 min. Doświadczenie założono metodą kompletnych bloków randomizowanych w ośmiu i czterech powtórzeniach. Jednostka pilotażowa wynosiła 50 ziaren. Dla określenia mikobiot zastosowano test agarowy po uprzedniej dezynfekcji ziarna 3% roztworem podchlorynu sodu przez 1 min. Stwierdzono różnice (P ≤ 0,001, P ≤ 0,05) pomiędzy obiektami doświadczenia. Najlepsze wyniki uzyskano dla czasów ekspozycji 30 i 10 min, uzyskując odpowiednio 42,85 oraz 52,05% redukcję ilości ziaren zakażonych Fusarium spp. dla ziarna hybryd “San Juan” i “H-159” w odniesieniu do kontroli. W odniesieniu do Fusarium monoliforme stwierdzono, że po czasie naświetlania 30 min nastąpiła redukcja o 53,74% dla hybrydy “San Juan”, a dla H-159 stwierdzono spadek o 61,7% po 10 minutach. Te wyniki wykazują, że promieniowanie UV-C może być użyteczne do stosowania jako zabieg zarodnikobójczy w przyszłych doświadczeniach na rożnych rodzajach ziarna.

This study investigates area-specific Sediment Yield (SY) in Mediterranean badland areas at different spatial scales using a SY-database compiled from scientific literature. Relationships between the plot and catchment characteristics and the corresponding SY-data are analyzed. Results indicate that in Mediterranean environments SY is larger than in other environments,especially in badlands where a high variability of SY is observed depending on the spatial scale. In intensively gullied badlands,a complex plot or drainage area (A) -SY relationship is observed: for A ranging between 10-5 and 10 ha,SY is very high (mean SY equals 475 t ha-1 yr-1),whereas for A greater than 10 ha,SY decreases with increasing A (mean SY less than 100 t ha-1 yr-1).

Opis:
It is a common practice to mount a catalytic converter directly at the outlet of the exhaust manifold in order to reduce the cold start emissions from the automotive engines by improving the light-off time. The so called Close-Coupled Converter, because of its nearness to the engine, is more exposed to non-uniform fluid flows comingfrom the individual manifold runners, what frequently yields a stream of gases flowing mainly through a section of the monolith causing the aging of the catalyst and low conversion efficiency, among other negative effects. Computational Fluid Dynamics (CFD) has became a very useful and widely used tool to analyze and optimize this kind of exhaust after-treatment systems in a relatively fast and accurate way for design purposes. There are several designs of exhaust manifolds whose shape and dimensions are mainly restricted not only by the engine characteristics but by the space constraints of the particular vehicles they are designedfor. In this work the commercial CFD code ANSYS FLUENT was used to evaluate and compare the effect of three shapes of exhaust manifolds on the fluid flow uniformity at the entrance of the Close-Coupled Converter. Pressure drop in the entire Manifold-Converter device is also an important parameter considered for the design evaluation. The manifolds investigated are of type cast, 4-2-1 and L-shaped, which are commonly used in the automotive industry.
