Opis:
Here we describe a new notoungulate mammal from the early Eocene (Itaboraian SALMA) of Chubut, Argentinian Patagonia, from the localities of Las Flores and Las Violetas Farm, represented by fragments of maxilla and isolated teeth. The specimens were found in the Las Flores Formation, Río Chico Group, and assigned to the Henricosborniidae, a primitive family within the order Notoungulata. Orome deepi gen. et. sp. nov. differs from other henricosborniids in a less developed metacone column in the upper molars, a larger metaloph in the third upper molar and a larger mean size. The morphometric analysis does not show any difference between the individuals of the two studied localities. The new addition to the henricosborniid diversity in Patagonia allows to provide a better understanding of the early radiation of notoungulates in South America.

Opis:
Structural properties were studied in the orthorhombic perovskite $La_{0.7}Dy_{0.3}Mn_{1-x}Zn_{x}O_3$, synthesized in the range 0 ≤ x ≤ 0.4. X-ray diffraction data, refined by the Rietveld analysis, shows for x < 0.1 the presence of stretched octahedra on the Mn-O plane, and, for x > 0.1, the existence of elongated octahedra along the c axis. Increased Zn doping causes a direct structural effect: one Zn atom distorts four neighboring MnO₆ octahedra on the Mn-O plane. It was observed that the unit cell volume containing Dy decreases as x increases, whereas the unit cell volume containing La increases as x decreases.

Opis:
Ten to 16 ethanol-soluble carbohydrate components were identified in the seeds of six Mexican wild lupins. The analysed carbohydrates included: monosaccharides, disaccharides, cyclitols, galactosyl cyclitols and raffinose family oligosaccharides. Stachyose and sucrose were the main carbohydrate component in the Lupinus montanus, L. rotundiflorus, L. exaltatus, L. mexicanus and L. elegans seeds. Only trace quantities of verbascose were detected in Lupinus mexicanus seeds. The analysed seeds accumulated 38 to 78 mg/g d.m. carbohydrates. The raffinose family oligosaccharides constituted 41 to 85.2% of the identified carbohydrate component pool. The analysed Lupinus seeds contained 3 to 8 unidentified carbohydrate components.

Opis:
A simple and efficient procedure for non-linear analysis of frames is presented, under the hypothesis that the non-linear effects, if appear, are concentrated in the beam-ends.We consider a damage model based on Continuum Damage Mechanics, but affecting the cross-section as a whole. The elastoplastic behaviour is included formulating the tangent elastoplastic stiffness matrix in such a way that the yield function, in terms of internal forces (axial, shear and bending moment), is affected by the damage in each plastic cross-section. After the verification of the model, an example of application is solved for different assumptions on the yield function (depending on the internal forces considered) with the damage being taken into account or disregarded. The differences on the collapse load, for each case, are shown and some conclusions obtained, among them that the method can evaluate in a more accurate way the load that causes the collapse of frames under increasing loading, considering a fully plastic non-linear analysis.
W pracy zaprezentowano prostą i skuteczną metodę nieliniowej analizy dwuwymiarowych ram przy założeniu hipotezy, że efekty nieliniowe, jeśli występują, są skoncentrowane na końcach belek tworzących układ ramy. Rozważono kontynualny model procesu zniszczenia obejmujący przekrój belki jako całość. Właściwości elasto-sprężyste materiału ujęto poprzez zdefiniowanie macierzy stycznej sztywności sprężysto-plastycznej w taki sposób, że funkcja uplastycznienia wyrażona w kategoriach obciążeń wewnętrznych (sił osiowych, tnących oraz momentu gnącego) zależy od stanu zniszczenia w każdym uplastycznionym przekroju. Po zweryfikowaniu modelu, rozwiązano przykład zastosowania analizy dla różnych założeń narzuconych na funkcję uplastycznienia (w zależności od wziętych pod uwagę obciążeń wewnętrznych) z uwzględnieniem zniszczenia lub bez. Dla każdego przypadku pokazano różnice w wartościach obciążenia zewnętrznego prowadzącego do wyboczenia ramy oraz sformułowano wnioski. Wykazano, że przedstawiona metoda nieliniowej analizy uplastycznienia pozwala na bardziej precyzyjne określenie krytycznych obciążeń prowadzących do zniszczenia konstrukcji.

Opis:
CONTRIBUTION OF EXAFS-LIKE TECHNIQUES TO THE DETERMINATION OF LOCAL ORDER: APPLICATION TO TRIBOLOGY: The determination of local order at atomic scale becomes more and more fundamental for understanding superficial phenomena such as tribology and catalysis. Among a few techniques available in this field, we are only concerned with the EXAFS-like ones (EXAFS, SEXAFS, EXELFS, SEELFS, etc.). The difficulties appearing all along the numerical treatment of such spectra are carefully analysed and a methodology is proposed in view to obtain reliable radial distribution functions. Some applications of these techniques are presented in two fields connected with tribology: friction induced amorphisation in high vacuum and characterization of interfacial solid bodies created during a wear process including an antiwear additive.

Opis:
In this work a strip of a transformation induced plasticity (TRIP) steel was welded using gas metal arc welding (GMAW) and Laser CO2 welding (LBW) processes and the resultant strength and ductility of the welded joints evaluated. It was found that LBW lead to relatively high hardness in the fusion zone, FZ where the resultant microstructure was predominantly martensite. The relative volume fractions of phases developed in the welded regions were quantitatively measured using color metallography combined with X-ray diffraction analyses. It was found that the heat affected zone, HAZ developed the maximum amount of martensite (up to 32%) in the steel welded using LBW besides a mixture of bainite, retained austenite and ferrite phases. In contrast, a relatively low percent of martensite (10.8%) was found in the HAZ when the GMAW process was implemented.
Pas ze stali typu TRIP poddano spawaniu elektrodą topliwą oraz spawaniu laserowemu i oceniono wytrzymałość i plastyczność uzyskanych połączeń spawanych. Stwierdzono, że spawanie laserowe prowadzi do uzyskania stosunkowo wysokiej twardości w strefie łączenia, gdzie powstała mikrostrukturę stanowi głównie martenzyt. Względne udziały objętościowe faz w spawanych obszarach zmierzono ilościowo za pomocą barwnej metalografii w połączeniu z dyfrakcyjną analizą rentgenowską. Stwierdzono, że w przypadku stali spawanej laserowo strefa wpływu ciepła zawiera najwięcej martenzytu (do 32%), a oprócz tego mieszanine bainitu, resztkowego austenitu i ferrytu. Natomiast w strefie wpływu ciepła uzyskanej podczas spawania elektrodą topliwą stwierdzono stosunkowo niską zawartość martenzytu (10,8%).

Opis:
Speckle technique is based on the light intensity distribution randomly formed when a laser light is reflected on a rough surface, creating a pattern of illuminated grains (constructively) and dark (destructive) on scales of 1 μm. When the samples are displaced or deformed, the speckle pattern is altered. In this paper we present speckle patterns obtained from samples of gastric mucosa that is physically altered for the carcinogenesis process. Biopsies were studied with different diagnoses and were grouped according to the characteristics of speckle patterns. Speckle patterns were obtained by illuminating the samples with green laser. Morphological parameters of the speckle patterns reveal existence of 3 descriptors: the average grain size, hydraulic radius and the radio of the Weddel disc, which showed a high, intermediate and low value. The comparison shows agreement between the histopathological diagnosis and the values obtained by the speckle technique, making this technique emerge as a new classification system for quantitative diagnosis of precancerous lesions.

Opis:
The overall aims of this project are to assess the safety and immunogenicity of the Schistosoma japonicum vaccine paramyosin among water buffaloes residing in endemic areas. The study was conducted in four villages in Leyte, the Philippines, an area highly endemic for schistosomiasis japonica. One hundred and fifteen (N=115) animals provided baseline stool samples for coprologic examination, with preliminary results using FLOTAC showing a 10% prevalence of schistosomiasis. Forty-nine (N=49) animals consented to treatment with 25 mg/kg Praziquantel, and 40, 36 and 32 animals consented to the first, second and third dose of the paramyosin vaccine, respectively. The safety trial involved the first 20 animals and included skin testing, vaccination, anaphylaxis monitoring, as well as hematology and serum chemistry analysis. Skin tests revealed that only three out of 20 animals exhibited redness at the injection site, with none greater than 1 cm. None of the animals exhibited anaphylaxis, and all hematology and serum chemistry markers were within normal range or were similar to pre-vaccination levels. None of the 40 animals administered with the first dose exhibited anaphylaxis, nor any of the subsequent vaccine doses. Immunogenicity assessment of sera collected prior to every vaccination and one month after the last dose showed that the paramyosin vaccine induced robust antibody responses to all animals, as assessed by ELISA. The cytokine levels of whole blood culture supernatants will be further assessed. Our findings demonstrate that the S. japonicum paramyosin vaccine is a safe, well-tolerated and immunogenic treatment among water buffalos residing in endemic areas.

Background. Physalis peruviana L. fruit contains nutritional and bioactive compounds of immense importance to public health and represents a potential ingredient for the development of functional foods and beverages. Objective. This study aimed to determine the chemical and nutritional composition as well as the antioxidant capacity of the P. peruviana L. fruit grown in Peru in three areas of the Central Andean region. Material and methods. Proximal and physicochemical analyses and estimation of mineral content, vitamin C, total carotenoids, total polyphenols, and antioxidant capacity (2, 2-diphenyl-1-picrylhydrazyl [DPPH] and 2, 2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) [ABTS] assays) were performed using standardized methods. Results. The fruits were collected from three regions of the Peruvian Andes (Ancash, Cajamarca, and Cusco). The results showed that the content of potassium (306.54–327.60 mg/100 g) and iron (12.93–14.47 mg/kg) was prominent. The Physalis fruit had high levels of vitamin C (47.20–52.20 mg/100 g), total polyphenols (68.17–83.40 mg equivalents of gallic acid/100 g), and carotenoids (1.12–1.73 mg β-carotene/100 g). Higher values for antioxidant capacity were obtained with the ABTS method (896–1003.33 μmol Trolox/100 g) than with the DPPH method (290–309 μmol Trolox/100 g). Conclusions. This study confirms that the P. peruviana fruit has properties that could provide important health benefits and that it could be used for the development of functional foods and food supplement.

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.

Here we report a new Early Pleistocene record of agamid lizards (Agamidae indet.) from the Spanish locality of Quibas (ca. 1.3–1.0 Ma), which represents the latest evidence of the family in Western Europe. Up to now, the family Agamidae was considered to have disappeared in this region at 1.8 Ma. This new record implies the survival of agamid lizards for a large part of the Early Pleistocene in the southernmost Iberian Peninsula, probably because of favourable climatic and environmental conditions. Consequently, the formerly detected Pliocene / Pleistocene boundary is no longer recognisable in the evolution of the herpetological assemblages in Western Europe.

Opis:
n this work, morphology of Beta vulgaris L. cells permeabilized with 0.7 mM of Triton X-100® was evaluated using digital image processing and concepts of fractal dimension (perimeter- area relations). Important morphometric changes were found when the contact-time with chemical agent was increased.The size of cells decreased, the cells lost the roundness and their shape was more sinuous; this behaviour was a result of a probable shrinkage caused by the excess of exposure with the permeabili- zation agent. Morphology of B. vulgaris cells after permeabili- zation, exhibited a fractal nature since the slope of the ratio of the logarithm of the perimeter vs logarithm of the area was higher than unit. Fractal geometry of the cell morphology was affected as a re- sult of the exposure to Triton X-100®. Those changes can be attri- buted to the loss of turgor and structure of the cell wall.

Opis:
Reactions between heavy-ions at various energy regimes produce many nuclear fragments which can be populated in highly excited states. The study of these fragments, detected at the end of their particle decay, is important to investigate nuclear forces and structure effects. In recent years there have been many efforts to extend these studies towards the drip-lines, i.e. to systems far from the β-stability valley, by using accelerated radioactive beams. The development of such infrastructures is accompanied by the development of more powerful detectors and associated electronics, capable to identify ions with very different sizes and kinetic energies. Here we give two examples which show how advanced arrays can contribute to the studies on nuclear phenomena. The examples come from the European FAZIA collaboration and from recent campaigns with the GARFIELD apparatus, the latter in operation at the INFN Legnaro Laboratory (Italy) where the SPES RIB facility is under construction.
