    Opis:
    In this work, the influence of both characteristics of the lens and misalignment of the incident beams on roughness measurement is presented. To investigate how the focal length and diameter affect the degree of correlation between the speckle patterns, a set of experiments with different lenses is performed. On the other hand, the roughness when the beams separated by an amount are non-coincident at the same point on the sample is measured. To conclude the study, the uncertainty of the method is calculated.

    Opis:
    The environmental characterization of the Lower Permian mesosaur−bearing strata of the Mangrullo Formation (Paraná Basin, northeastern Uruguay) has been controversial. Historically, marine conditions were suggested for this unit, despite the absence of any normal marine fossils. More recently, some authors have argued for freshwater to brackish settings, inferring fluctuating environmental conditions, which would have generated abrupt changes in the composition of the communities. Mesosaurs are the only tetrapods found in this unit, and they colonized the basin at the time of highest isolation, and apparently increased salinity, coincident with a gradual global rise in aridity. An assemblage of extremely low diversity (the “mesosaur community”) developed, with mesosaur reptiles, pygocephalomorph crustaceans, and the vermiform producers of the trace fossil Chondrites as the dominant components. This community may have existed under temporary hypersaline, lagoon−like conditions, as suggested by ecological, anatomical and physiological attributes of its member taxa. This interpretation is supported by sedimentological and mineralogical features of the enclosing rocks, also seen in the correlative Brazilian Iratí and South African Whitehill formations. In the Uruguayan deposits, as well as in their Brazilian correlatives, relatively close volcanic events affected the basin. This particular environment, where bottom waters were depleted of oxygen and hypersaline, retarded decay of the carcasses, and precluded the development of bioturbating organism, and together with bacterial sealing, favoured exquisite preservation of the fossils, including soft tissues. This leads us to consider the fossil−bearing strata of the Mangrullo Formation as a Konservat−Lagerstätte, the oldest known for South America.

    Opis:
    In this article, a review of energy mix, electricity production and emissions from power sector of Ethiopia, Pakistan, Poland, Spain and Turkey is investigated. The choice of countries is varied to let see how it looks in different parts of the world. The time interval chosen to show some changes that follow. Primary energy consumption of the countries is given in percentage of resources used. Electricity production of the countries are analyzed in 2006 and 2011 respectively. Furthermore, emissions of CO2, NOx SOx and PM are compared with respect to population and area and GDP. As a result, the analysis of the highest and lowest emitting countries are presented in the article.
    W artykule przedstawiono przegląd źródeł miksu energetycznego, produkcji energii elektrycznej i emisji z sektora energetycznego w Etiopii, Pakistanie, Polsce, Hiszpanii i Turcji. Wybór krajów jest zróżnicowany aby przybliżyć jak wygląda to w różnych częściach świata. Przedział czasu dobrano tak, aby pokazać pewne zmiany, które następują. Zużycie energii pierwotnej krajów podane jest w procentach zasobów używanych. Produkcja energii elektrycznej z wymienionych krajów jest analizowana odpowiednio dla danych z roku 2006 i 2011. Ponadto, emisje CO2, NOx SOx i PM są porównywane pod względem ludności , powierzchni i produktu krajowego brutto - PKB. W rezultacie, przedstawiono analizę najbardziej i najmniej uciążliwych pod względem emisji krajów porównywanych.

    Opis:
    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:
    Root-knot nematodes, genus Meloidogyne, are among the most plant damaging pathogens worldwide. The action of natural products against plant pathogens has been investigated to assess their effectiveness in the control of diseases. Thus, the present study aimed to evaluate the phytochemistry potential of the Ficus species for the control of Meloidogyne javanica. In vitro inhibitory activity assays were performed with crude ethanolic extracts of leaves and branches from 10 Ficus species. Among these, Ficus carica extracts exhibited strong paralysis activity against second stage juveniles (J2) (EC50 = 134.90 μg ∙ ml–1 ), after 72 hours. In addition, high efficacy was observed in egg-hatching inhibition at different embryonic stages. Microscopy analysis revealed severe morphological alterations in the nematode tissues at the J2 stage, as well as immotility of juveniles released from eggs in the presence of F. carica extracts. The efficacy of the treatments for the other species was very low. These differences were supported by the variation in the compound classes, mainly for alkaloids and metabolite profiles by Gas Chromatography/Mass Spectrometry (GC/MS) when F. carica was compared with the other species. The results indicated that F. carica is a promising source for the isolation and identification of molecules capable of acting in the control of M. javanica.
