Opis:
The Greek city of Emporion is one of the few Greek emporia which ultimately became a polis. Consequently, the city had to adapt the previously held structures of an emporion to cope with the new circumstances which being a polis required; thus its urban space, territory, population, laws, government had to be modifi ed in the conversion from one situation to another. Furthermore, this change had to be fulfi lled in the midst of a non-Greek environment, which obviously had consequences in the development of Greek identity within the city. Fortunately, in the case of Emporion we have both archaeological and literary evidence (although not very abundant) to observe these processes. The aim of this paper is, consequently, to consider this evidence in order to see how interactions worked in Emporion itself as well as in the surrounding region in different historical moments and how those interactions contributed to shaping several interrelated identities within the Greek city, which also became a strong point for building the identity of the non-Greek peoples in that region of north-eastern Iberia.

Opis:
The aim of this study is to describe the impact on particle matter and CO2 emissions of converting an existing heavy-duty diesel engine for on-highway truck applications to a dual-fuel engine (diesel + natural gas), especially in transient operation. A dual-fuel engine with homogeneous gas charge injection in the intake line before turbocharger was considered. The results showed the feasibility of this kind of technology for transient operation reaching a significant reduction of particle matter plus a decrement in CO2 emissions at the expense of a small decrement of brake fuel conversion efficiency and an increment of unburned hydrocarbons in the exhaust gases.

Opis:
Due to their nutritional and sensorial characteristics, tropical fruits like guava, mamey sapote, and passion fruit are regularly incorporated into daily diets. Their by-products, especially peels, are approximately 10 to 35% of their weight and possess an important content of bioactive compounds, such as dietary fiber and phenolics. The nutritional, technological, physio-functional properties and phenolic compound compositions of guava, mamey sapote, and passion fruit peels were studied. Peels had promising techno- and physio-functional characteristics, good dietary fiber contents (45.18-61.42 g/100 g), and phenolic profiles with ferulic acid, gallic acid, p-coumaric, and catechin as the main compounds. Peel powders also showed excellent DPPH radical scavenging activity (125.3–252.4 µmol TE/100 g) and Trolox equivalent antioxidant capacity, TEAC (369.2–656.8 µmol TE/100 g). The α-amylase and lipase inhibitory activity varied from 28.15 to 51.4% and 30.89 to 57.15%, respectively. Higher values of α-glucosidase inhibition capacity were found, ranging from 51.64 to 70.32%. The chemical composition and properties reported in the present work suggest that peel powders of these guava, mamey sapote, and passion fruit could be used as constituents in different foods, such as bakery and meat goods, with beneficial health effects like control of hyperglycemia, improved intestinal function, and control of overweight; however, more studies are necessary for animal models and humans to confirm these bioactivities conclusively.

Opis:
A novel method for calculation of the entropy measure in wavelet space is proposed. This perceived-based entropy measure uses a Second Order Model entropy estimator, in which the occurrence of neighbors is considered in formulation. It has the intention to allow the implementation of a more suitable measure in coding processes and a relationship between the metric and the description of perceptual features. This method is used for the Rate-Distortion optimization in order to improve the bit-allocation coding algorithm, demonstrating that the wavelet-based entropy estimates a truncation step close to the target rate. The hypothesis is founded in the effect of distortion on the coefficient allocation. Because entropy measure is a close approximation of the conditional probability of image in multiresolution space, it provides an adequate representation for the information of a Detail feature. A definition of Detail-based homogeneity variance criteria is used for the information quantity - wavelet representation space, in order to find the image that fits a given Quality Level criteria. Experimental results are obtained for artificial and natural databases.

Amorphous ribbons of composition (Co$\text{}_{0.95}$Fe$\text{}_{0.05}$)$\text{}_{100-x}$Si$\text{}_{0.4x}$ B$\text{}_{0.6x}$, with x=25 and 30 were prepared by the melt-spinning technique. Current annealings at 600 mA were performed for annealing times between 15 s and 60 min. The magnetoimpedance response was investigated by submitting the ribbons to ac currents at frequencies in the 10-200 kHz range, with amplitudes between 1 and 15 mA (rms), and measuring their voltage response. The observed results show that a transverse anisotropy is induced by the thermal treatments, which can be evaluated by means of the magnetoimpedance effect. Due to its lower Curie temperature, the x=30 ribbons exhibited lower sensibility to the current annealings.

Opis:
The applications of nanostructured materials are close related to their shape and properties. A comprehensive understanding of the properties modification by controlling the material size, thickness or shape is of key importance. A nanostructure can become a building block to create the upcoming nano-technological stages, where the final characteristics of devices can be fine-tuned from design. In this report it is shown that several physicochemical properties, such as refractive index, band gap or thermal resistance can be modified in a controlled fashion. ALD is a very versatile fabrication technique for building nanotubes (Al2O3 and TiO2), nanolaminates (Al2O3-ZnO, Y2O3-ZrO2 and ZrO2-TiO2) and core-shell materials (diamond-Al2O3) with an exquisite precision on the thickness of the coatings.

Opis:
In the High Valleys of Mexico maize is produced with varied yield and quality which sometimes do not meet the parameters established by maize flour milling and nixtamalization industry for making tortilla. Therefore, an evaluation of the yields and quality of the grain of maize hybrids (Zea mays L.) and their relationship with the environment was performed. During the spring-summer cycle 2012, the hybrids HP-1, H-52, H-68, HP-2, H-70, Buho, HP-3, H-57E, H-64, Prospecto-1, H-72 and H-66 were evaluated in Texoloc and Benito Juárez (2240 and 2530 masl), Tlaxcala, Mexico in a design of completely randomised blocks with three replications. Grain yield (GY), thousand grain weight (TGW), hectolitric weight (HW), width (WG), length (LG) and thickness (TG) of grains were measured. The results showed highly significant differences (p = 0.01) between locations, hybrids and the interaction locality x hybrids for physical parameters. Among the localities, Texoloc had 86.59% and 24.32% higher GY and TGW compared to Benito Juarez, respectively, while the HW was slightly lower (73.68 kg hL-1). Average yields of the hybrids were 7.7 t ha-1; HP-2, HP-3, H-57E and H-66 hybrids had yields of more than 8 t ha-1 and the lowest yield was noted for H-70. The hybrids had an average HW of 74.30 kg hL-1; HP-1, H-68, H-70, Buho, HP-3 and H-72 had values > 74 kg hL-1, complying with the provisions of the quality standard NMX-FF034/1-SCFI- 2002 for maize destined for the nixtamalization process. The variation in agroclimatic conditions between the localities affected the yield and physical quality of maize grain.
W Wysokich Dolinach Meksyku produkowana jest kukurydza o zróżnicowanej jakości i poziomie plonowania, która nie zawsze spełnia wymagania przemysłu młynarskiego i nixtamalizacji mąki kukurydzianej do produkcji tortilli. Z tego powodu przeprowadzono badania, mające na celu ocenę plonowania i jakości ziarna hybryd kukurydzy (Zea mays L.) oraz ich zależności od warunków środowiskowych. W sezonie wiosenno-letnim roku 2012 przeprowadzono badania na hybrydach HP-1, H-52, H-68, HP-2, H-70, Buho, HP-3, H-57E, H-64, Prospecto-1, H-72 oraz H-66 w Texoloc i Benito Juárez (2240 i 2530 m n.p.m.), Tlaxcala w Meksyku. Badania przeprowadzono w systemie bloków losowych, w trzech powtórzeniach, dokonując pomiarów plonu ziarna, masy tysiąca ziaren, masy hektolitra ziarna oraz szerokości, długości i grubości ziarna. Stwierdzono istotne różnice (p = 0,01) pomiędzy lokalizacjami, hybrydami oraz interakcjami lokalizacja- hybryda w zakresie parametrów fizycznych ziarna. Wartości plonu i masy 1000 ziaren w Texoloc były wyższe odpowiednio o 86,59% i 24,32% w porównaniu do wartości otrzymanych w Benito Juarez, podczas gdy wartość masa hektolitra była nieznaczenie niższa (73,68 kg·hL-1). Średni plon ziarna hybryd wyniósł 7,7 t·ha-1; plony hybryd HP-2, HP-3, H-57E i H-66 były powyżej 8 t·ha-1, a najniższy plon uzyskano dla hybrydy H-70. Średnia wartość masy hektolitra dla hybryd kukurydzy wyniosła 74,30 kg·hL-1; dla hybryd HP-1, H-68, H-70, Buho, HP-3 i H-72 były > 74 kg·hL-1, spełniając wymagania jakościowe normy NMX-FF034/1-SCFI-2002 dla kukurydzy przeznaczonej do procesu nixtamalizacji. Zróżnicowanie warunków agroklimatycznych pomiędzy badanymi lokalizacjami miało wpływ na plonowanie i charakterystyki fizyczne ziarna kukurydzy.

The structure of a family of high entropy alloys based on the composition CoCrFeNi, to which Pd and Sn have been added, is presented. The results stem from combined investigations by atom probe tomography as well as by scanning and transmission electron microscopy on samples produced by arc melting. Although CoCrFeNi is of fcc structure, the sample is not homogeneous on atomic scale. The addition of Pd as a fifth element retains the fcc lattice with the indication of the coexistence of at least two additional phases. The addition of Sn changes the general structure considerably.

Opis:
As neuron models become more plausible, fewer computing units may be required to solve some problems; such as static pattern classification. Herein, this problem is solved by using a single spiking neuron with rate coding scheme. The spiking neuron is trained by a variant of Multi-objective Particle Swarm Optimization algorithm known as OMOPSO. There were carried out two kind of experiments: the first one deals with neuron trained by maximizing the inter distance of mean firing rates among classes and minimizing standard deviation of the intra firing rate of each class; the second one deals with dimension reduction of input vector besides of neuron training. The results of two kind of experiments are statistically analyzed and compared again a Mono-objective optimization version which uses a fitness function as a weighted sum of objectives.

Opis:
The understanding of the structure and the stability of high entropy alloys is still incomplete and the mechanisms behind the composition-property relationships are unclear. One reason is that few systematic and accurate determinations of their composition-dependent structure on atomic level have been made. In this paper some results on the structure obtained by X-ray and neutron diffraction of the CoCrFeNi alloy, to which Pd, Sn and Cu have been added in different amounts, are reported. The investigations make it obvious that none of the alloys is completely homogeneous, as has earlier been suggested, and that they do not form a perfect solid solution.

Opis:
The agronomic management of maize (Zea mays L.) modifies the structure and composition of maize grain and its products like flour, masa, and tortillas. Results have shown that the protein content in flour obtained from maize grains treated with nejayote applied at 150 m3 ha-1 (10.36 g × 100 g-1) and nejayote applied at 75 m3 ha-1 with ovine manure applied at 25 t ha-1 (10.17 g × 100 g-1) was higher than that determined in flour treated with chemical fertilizer (10.05 g × 100 g-1). The flours obtained from maize fertilized without nejayote showed the highest viscosity values and the lowest values were for chemical fertilizer (2816 mPa s) and 75 m3 ha-1 of nejayote with ovine manure applied at 25 t ha-1 (2498 mPa s). The highest elastic and viscous moduli were obtained for masa with the following fertilization regimes: 75 m3 ha-1 of nejayote with 25 t ha-1 of ovine manure, and 150 m3 ha-1 of nejayote with 25 t ha-1 of ovine manure and the lowest values of these parameters were obtained for 75 m3 ha-1 of nejayote with 50 t ha-1of ovine manure. The cohesiveness of masa was the lowest for maize fertilized with nejayote applied at 75 to 150 m3 ha-1, and 50 t ha-1 of ovine manure. The highest concentration of 150 m3 ha-1 for nejayote and the lowest level for ovine manure applied at 25 t ha-1 had a positive influence on the production of nixtamal and tortilla.

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.
