Opis:
The subject of the article António Salazar and his "New State" – the genesis, ideological foundations, the specificity is the long-term Prime Minister of Portugal, and de facto its dictator, who formulated the concept of state functioning, which was later defined as the New State (Estado Novo). The text shows the leader of the Portuguese Republic as a man and an ideologist as well as the process of development of his views on the background of landmark events in the Iberian Peninsula in the early twentieth century. The aim was to present all the theoretical assumptions of Estado Novo's ideas rather than its practical implementation after the proclamation of the New State constitution in 1933. That is why the mentioned date closes the article's timing framework. The ideology of António Salazar and the structures he created survived in virtually unchanged form until 1974. Hence, the second important goal of the text is to try to answer the question of Salazar's government's longevity.

Opis:
On Precariousness of Maritime Labor. The Case of Mexico (1980–2006) Currently, the debate on employment and economic performance develops along the lines of two traditional approaches to labor. One side of the debate is represented by the ‘neoclassical’ promoters of the idea that the market is the only factor regulating relations between employers and workers; the other side is represented by institutionalists proposing models for reform of labor markets based on business productivity and competitiveness of nations. However, those occupying the middle ground integrate in their arguments both the need for economic efficiency and the need for social justice, recognizing that forms of state regulation and control in the labor market are necessary. Hence, also the situation of maritime transport is suspended between two systemic assumptions: first, that the regulation of maritime labor should be governed by international standards, with no institutional freedom for each country to design its own rules, and that it should be based on a general model ratified by most nations. Second, compared to the neoclassical model, the present day condition of the shipping industry testifies to the fact that the ‘lack of laws regulating competition is responsible for the serious deterioration of the working conditions’ and that it curtails the space of collective negotiations warranting the seagoing personnel acceptable working conditions. Such a shortage of international regulations renders healthy balance in labor relations impossible. However, despite the present-day diagnosis of the situation, the discussion on the likely paths for the development of labor regulations on board of merchant vessels tends towards arguments presented by the institutionalists, who advocate the need to establish forms of regulation and state control over the market and its players. At present, such a form appears to be the only one leading to the achievement of at least a measure of labor protection at sea. Today, the mechanisms of the market for maritime work impacting the living conditions of the personnel may be seen as exemplified by the phenomenon of the so-called ‘crews of convenience’, i.e.: crews hired under precarious working conditions, which the workers accept seeing no other alternative to unemployment. Such contracts, signed without government or union mediation, in the context in which no international fair trade laws respecting work at sea exist, reinforce the case for national and international regulation. The phenomenon of the crews of convenience and, generally, the intensification of the deregulatory tendencies in the shipping industry, point to the actual as well as potential role of trade unions in the sector. The globalization of shipping has taken unions, born in the context of state regulations, by surprise. The proliferation of free flag shipping and the consequent reduction of national fleets, caused by the liberalization of markets, resulted simultaneously in the increase of the number of sailors hired under substandard conditions and in the growth of the scale of the exchange of goods across the world. The deregulation in this sector allows for both phenomena to expand: on the one hand, it facilitates the free registration of vessels, it energizes the search for tax havens, but on the other, it fosters the free choice in hiring and firing crews and in pricing the freight solely on the basis of the market principles of supply and demand. Exemplifying the situation are the characteristics of the system of labor regulation in Mexico’s maritime labor law, which show that the actual dynamics of the labor market has been accommodated by the system’s flexibility. Yet, it must be noted that this flexibility of flags of convenience effectively undermines the safety of employment for Mexican sailors, because in the context of the reduction of the national fleet, given the precarious conditions of labor, crews must compete with Asians, who make up 80% of the global maritime workforce. To mitigate this situation, efforts have been taken by some nations to find a solution to the problem. Such efforts have been recorded by the International Maritime Organization (IMO) and the International Labour Organisation (ILO), who promote the implementation of international norms and standards of their application. As a result, the Maritime Labour Convention (2006), sponsored by the ILO, has become a milestone in the process leading to improvements in the international working environment. With its working documents amounting to more than 65 conventions and recommendations, its adoption in March 2006 and implemenation on August 21st, 2013, will continue to impact the lives of 1.2 million seafarers in the world, whose work makes 80% of world trade possible. Therefore, it is important to study the effects of the implementation of such regulations in the context of the actual work conditions on board of on ships since international organizations (such as the ILO, which seeks to curb casualization of employment through international rules that protect the interests of workers on board) became active in the process. In this context, the first part of this article illustrates how the merchant navies weaken in the face the processes of economic liberalization (which translates into working conditions on board). In the second part, this phenomenon is studied on the basis of the case of Mexico. Finally, the impact of the 2006 Convention, which aims to address the global maritime job insecurity, is analyzed, with particular emphasis on the prospective consequences of the systematic implementation of the Convention’s regulations of the Convention, whose cornerstone is the protection of the seagoing personnel, yet whose provisions meet with a serious degree of resistance on the part of the advocates of deregulation.

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.

The availability of dynamic resource management will be crucial for the deployment of future wireless systems characterized by high data rate services with rigid quality of service demands. Flexible radios appear as the technological answer required to achieve constraint goals under different channel conditions and transmission scenarios. This paper is focused on enhancing another step of flexibility within the resource management by including an efficient handling of computing resources. This concept towards flexible architectures represents a key word for a real successful implementation due to the relationship between the radio applications, which face the scarcity of resources within a heterogeneous environment, and the processing power needed to execute them.

The aim of the article is to show how the creator of Estado Novo was perceived by the youngest generation throughout almost 40 years. It is also an indirect attempt to appraise the moods of young Portuguese people and children of foreigners who had been living then in Portugal, to outline their attitude to the regime, to show the background of the reality which had been described in their letters. The analysis of over 240 letters and postcards, written in the period of 1929–1968 and addressed to the creator of Portuguese dictatorship, collected in the Institute of the National Archives (The National Archive of Torre do Tombo) was the origin of writing the text.

Opis:
Sections yielding late Maastrichtian ammonite assemblages are rare in Latin America and precise biostratigraphic correlation with European type sections remains difficult. In all, the extinction pattern of ammonites appears to differ between sites in southern high latitudes and those in the tropics to subtropics. In austral sections of Chile, and possibly also in southern Argentina, diverse assemblages range throughout most of the substage and then show a gradual decline prior to the Cretaceous–Paleogene (K–Pg) boundary. Further north, in northeast Brazil, only two genera (Diplomoceras, Pachydiscus) range into the uppermost Maastrichtian, but disappear within the last 0.3 Ma of the Cretaceous. In tropical sections of Columbia and Mexico, the decline of ammonites started earlier and Sphenodiscus is the last ammonite known to occur in the late Maastrichtian. In all sections revised here the disappearance of ammonites was completed prior to the end of the Maastrichtian and was thus independent of the asteroid impact at, or near, the end of the Cretaceous.

Opis:
This study is based on the paradox that the democratic values sustaining the West during the Cold War were not applied in all anti-Communist countries, specifically in the Iberian countries. For the Iberian Peninsula to be a block, it was necessary for Portugal, which had been part of the Hispanic Monarchy, to abandon the ongoing mistrust of its neighboring country, founded on the so-called perigo espanhol ("Spanish danger"). Cordial relations between Salazar and Franco contributed to the Portuguese losing their feeling of mistrust. The reason for this was that the Regime leaders in Spain during the Second World War, as can be seen from Army General Staff documents serving as the basis for this study, saw Portugal as a true friend and believed that both countries had to work together to avoid becoming involved in the war. The Iberian Block survived and when the Cold War started, Portugal sided firmly with the West.

Opis:
Glaucoma is one of the main causes of blindness worldwide. Periodical retinal screening is highly recommended in order to detect any sign of the disease and apply the appropriated treatment. Different systems for the analysis of retinal images have been designed in order to assist this process. The segmentation of the optic disc is an important step in the development of a retinal screening system. In this paper we present an unsupervised method for the segmentation of the optic disc. The main obstruction in the optic disc segmentation process is the presence of blood vessels breaking the continuity of the object. While many other methods have addressed this problem trying to eliminate the vessels, we have incorporated the blood vessel information into our formulation. The blood vessels inside of the optic disc are used to give continuity to the object to segment. Our approach is based on the graph cut technique, where the graph is constructed by considering the relationship between neighbouring pixels and by the likelihood of them belonging to the foreground and background from prior information. Our method was tested on two public datasets, DIARETDB1 and DRIVE. The performance of our method was measured by calculating the overlapping ratio (Oratio), sensitivity and the mean absolute distance (MAD) with respect to the manually labeled images.

Opis:
Using ultrastructural cytochemical techniques we have found differences in the distribution of surface coat components between the invasive protozoan parasite Entamoeba histolytica and the non-invasive Entamoeba dispar. Carbohydrate-containing components and anionic sites in the cell surface of both species were detected by staining with ruthenium red and cationized ferritin, respectively. Ruthenium red staining revealed a thicker surface coat in E. histolytica trophozoites, whereas trophozoites of E. dispar showed a higher concentration of cationized ferritin particles on its surface. Mannose or glucose residues were found at the plasma membrane of both parasites treated with Concanavalin A (Con A)-peroxidase; the surface reaction product was more evident in E. dispar, compared with E. histolytica. Con A rapidly produced surface caps in E. histolytica trophozoites, whereas E. dispar showed a much less efficient mobilization of surface Con A receptors. Agglutination with Con A produced much larger clumps in E. histolytica in comparison with E. dispar. In turn, biotinylation assays revealed striking differences in the composition of surface membrane proteins in both amebic species. Overall, these results further emphasize the phenotypic differences between these two common parasites of the human intestinal tract, once considered to be the same protozoan.

Opis:
A major goal in modern flight control systems is the need for improving reliability. This work presents a health-aware and fault-tolerant control approach for an octorotor UAV that allows distributing the control effort among the available actuators based on their health information. However, it is worth mentioning that, in the case of actuator fault occurrence, a reliability improvement can come into conflict with UAV controllability. Therefore, system reliability sensitivity is redefined and modified to prevent uncontrollable situations during the UAV’s mission. The priority given to each actuator is related to its importance in system reliability. Moreover, the proposed approach can reconfigure the controller to compensate actuator faults and improve the overall system reliability or delay maintenance tasks.

Literature about PES sustains that increasing tenure security might be an additional element of participating in such programs. We focused on the “Socio Páramo” conservation program to analyze how the inclusion of land in this program has influenced perception on limits and tenure security for the local communities. With two case studies in the high grasslands (páramo) of Ecuador, we first used sketch maps to elicit how the area inscribed in the PES program has modified the spatial structures of the community territory and what type of limits are found in this territory. Then, we conducted narrative walking to track GPS points with descriptions of land uses, perceived communitarian limits and narratives about meaning or concerns with regard to limits for the community and the relation between the legalized area inscribed in the PES program and tenure security. Maps were produced through GIS support and narratives were analyzed through thematic coding. The study reveals that: a) legal tenure obtained in frame of PES implementation is perceived as a pre-condition to participate in the program and has influenced positively or negatively land tenure security for the entire community; b) knowledge about community limits of páramo is the main concern for elder members, who regard this knowledge as the key element to maintain community cohesion. We conclude that participatory mapping is a powerful tool to elucidate concerns about limits, rules and control over land use and persistence of communitarian life, elements that should be considered when implementing PES.
W artykule przedstawiono, w jaki sposób mapowanie partycypacyjne może przyczynić się do zrozumienia lokalnych znaczeń w zakresie ograniczeń społeczności i postrzegania bezpieczeństwa posiadania wśród rolno-pasterskich społeczności Andów, które uczestniczą w programie płatności z tytułu świadczeń na rzecz ekosystemu (PES). Literatura przedmiotu wskazuje, że zwiększenie bezpieczeństwa posiadania może być dodatkowym elementem uczestnictwa w takich programach. Autorzy skupili się na programie ochrony „Socio Páramo” w celu przeanalizowania, w jaki sposób włączenie gruntów do tego programu wpłynęło na kwestię postrzegania limitów oraz bezpieczeństwa wśród lokalnych społeczności. Zostały zrealizowane dwa studia przypadków na wysoko położonych pastwiskach (páramo) w Ekwadorze. Najpierw użyto map szkicowych, aby dowiedzieć się, w jaki sposób obszar wpisany w program zmodyfikował struktury przestrzenne terytorium społeczności i jaki typ ograniczeń znajduje się w danej strukturze. Następnie przeprowadzono spacery narracyjne. Badanie ujawniło, że: a) tytuł własności gruntów uzyskany w ramach wdrażania programu jest postrzegany jako warunek wstępny uczestnictwa w programie; b) kwestia wiedzy na temat ograniczeń społeczności páramo jest głównym problemem w przypadku osób starszych, którzy uważają taką wiedzę za kluczowy aspekt, jeśli chodzi o utrzymanie spójności danej społeczności. Wnioskujemy, że mapowanie partycypacyjne jest skutecznym narzędziem służącym wyjaśnianiu obaw dotyczących ograniczeń, zasad i kontroli użytkowania gruntów oraz trwałości życia wspólnotowego, czyli elementów, które należy uwzględnić przy wdrażaniu PES.

Opis:
The textile industry is very important because its products are widely used by society, however, this activity has a great contribution to the contamination of water resources due to its effluents that contain large amounts of colorants, among which is the blue of methylene (MB) and methyl orange (MO) that can cause damage to the health of living being. For this reason the present study concerned the removal of these dyes by adsorption using Eichhornia Crassipes (Water lily) with different treatments. The results show that the chemisorption removal process using two sites per dye molecule having an exothermic nature for the water-treated lily and for the NaOH-treated lily is endothermic. The maximum adsorption capacities of 228.9 mg/g for MB (60 °C) and 155.38 mg/g (30 °C) for MO with the NaOH treatment were achieved. The SEM analysis shows that there are significant changes in the surface due to the treatments. The XRD patterns indicate that with the pretreatment with NaOH the crystallinity of WL increases while the treatment with water maintains the presence of amorphous cellulose. In the FTIR spectra, the bands corresponding to different functional groups such as lignin, cellulose and hemicellulose that participate in the adsorption of both dyes are observed.

Opis:
Soil acidity is one of the factors affecting agricultural productivity worldwide, and it is corrected with materials from carbonates or hydroxides of Ca and Mg of different origins, including products from the cellulose industry such as ash + dregs (AD) and ash + dregs + sludge (ADS). Field experiments in a split plot design were conducted to evaluate the cellulose industry residues on chemical properties associated with soil acidity in three volcanic soils in Chile, cultivated with wheat in the 2019-2020 season. Treatments included a control without amendment, CaCO3 at an adjusted dose to achieve pH 6.0 (dose 1) and AD and ADS at dose 1 and double dose 1 (dose 2). Results indicated that AD and ADS in the three soils increased pH in the first 30 to 120 day after being applied, and achieved the same overall acidity correction effect at dose 1, with values that increased from pH 5.85 of control to 5.99 and 6.10, for dose 1 of AD and ADL respectively, at Santa Rosa location. In Carillanca location, the increase was from 5.52 of control to 6.27 and 6.24 for AD and ADL respectively, and in Remehue location – the soil reaction rose from pH 5.54 of Control to 5.91 and 5.89 for AD and ADL respectively (p<0.05). Using AD at dose 1 in the three soils had less effect on increased exchangeable Ca, but a greater effect on exchangeable Na and K concentrations. Using ADS at dose 1 showed a quantitatively lower effect on exchangeable Ca and higher exchangeable Mg and Na concentrations in soils. Results indicate that AD and ADS are an alternative to CaCO3.

La presente investigación analiza las relaciones entre los Estados Unidos de América y Venezuela en tiempos del gobierno democrático del general Isaías Medina Angarita. Partimos de la hipótesis que considera que las relaciones entre Venezuela y los Estados Unidos en función del reconocimiento diplomático y de la consecuente aceptación política estuvieron condicionadas por factores de orden económico y político derivado por el interés estadounidense en el petróleo venezolano y por la necesidad de garantizar la estabilidad de los mercados comerciales, inclusive durante la Segunda Guerra Mundial.
This research paper analyzes the relations between the United States of America and Venezuela in times of the democratic government of General Isaías Medina Angarita. We start from the hypothesis that the relations between Venezuela and the United States, based on diplomatic recognition and the consequent political acceptance, were conditioned by economic and political factors derived from the US interest in Venezuelan petroleum and the need to guarantee stability of commercial markets, even during World War II.
