Fully Adaptive Ridge Detection Based on STFT Phase Information Colominas, Marcelo Alejandro; Kuppel, Sylvain; Pham, Duong-Hung This letter deals with the problem of the estimation of the instantaneous frequencies of the modes of multicomponent signals from their linear time-frequency representations. In most approaches, such an estimation consists of extracting the ridges associated with each mode in the time-frequency plane. A major issue associated with these techniques is that ridge detection relies on some ad-hoc parameters which essentially bound the modulation of the studied modes and put some constraints on the type of filter used in the time-frequency representation. In this paper, we alternatively propose a novel fully adaptive approach for ridge detection whose relevance is shown throughout numerical simulations.

Platelet toll-like receptors mediate thromboinflammatory responses in patients with essential thrombocythemia Marin Oyarzún, Cecilia Paola; Glembotsky, Ana Claudia; Goette, Nora Paula; Lev, Paola Roxana; de Luca, Geraldine; Baroni Pietto, Maria Constanza; Moiraghi, Beatriz; Castro Ríos, Miguel A.; Vicente, Angeles; Marta, Rosana Fernanda; Schattner, Mirta Ana; Heller, Paula Graciela Essential thrombocythemia (ET) is comprised among chronic myeloproliferative neoplasms (MPN) and is caused by driver mutations in JAK2, CALR and MPL, which lead to megakaryocyte proliferation and prominent thrombocytosis. Thrombosis remains the main cause of morbidity in ET and is driven by the interplay between blood cells, the endothelium, the clotting cascade and host-derived inflammatory mediators. Platelet activation plays a key role in the thrombotic predisposition, although the underlying mechanisms remain poorly defined. In addition to their role in hemostasis, platelets participate in innate immunity and inflammation owing to the expression of toll-like receptors (TLR), which recognize inflammatory signals, triggering platelet functional responses. Considering the impact of inflammation on ET procoagulant state, we assessed the contribution of TLR2 and TLR4 to platelet hemostatic and inflammatory properties in ET patients, by using Pam3CSK4 and lipopolysaccharide (LPS) as specific TLR2 and TLR4 ligands, respectively. TLR2 ligation induced increased surface translocation of α-granule-derived P-selectin and CD40L, which mediate platelet interaction with leukocytes and endothelial cells, respectively, and higher levels of dense granule-derived CD63 in patients, whereas PAC-1 binding was not increased and LPS had no effect on these platelet responses. Platelet-neutrophil aggregate formation was elevated in ET at baseline and after stimulation of both TLR2 and TLR4. In addition, ET patients displayed higher TLR2- and TLR4-triggered platelet secretion of the chemokine RANTES (CCL5), whereas von Willebrand factor release was not enhanced, revealing a differential releasate pattern for α-granule-stored inflammatory molecules. TLR-mediated hyperresponsiveness contrasted with impaired or preserved responses to classic platelet hemostatic agonists, such as TRAP-6 and thrombin. TLR2 and TLR4 expression on the platelet surface was normal, whereas phosphorylation of downstream effector ERK1/2 was higher in patients at baseline and after incubation with Pam3CSK4, which may partly explain the enhanced TLR2 response. In conclusion, exacerbated response to TLR stimulation may promote platelet activation in ET, boosting platelet/leukocyte/endothelial interactions and secretion of inflammatory mediators, overall reinforcing the thromboinflammatory state. These findings highlight the role of platelets as inflammatory sentinels in MPN prothrombotic scenario and provide additional evidence for the close intertwining between thrombosis and inflammation in this setting.

Description of the putative mature larva of the Neotropical genus Stenhelmoides Grouvelle (Coleoptera: Elmidae) Gonzalez Cordoba, Marcela; Martínez Román, Nicolás Rafael; Zúñiga, María del Carmen; Manzo, María Verónica; Archangelsky, Miguel Stenhelmoides Grouvelle is a Neotropical genus of Elmidae and although it exhibits a wide distribution, until now no larvae had been associated with adults of this genus. Larvae, very likely belonging to this genus, were associated based on co-occurrence with adults. Eleven larvae and nine adults were examined from ten localities at altitudes between 30 and 682 m a.s.l. in the Andean, Caribbean and Pacific regions in Colombia. Mature larvae of the Stenhelmoides rufulus (Hinton) are described and illustrated for the first time. A larval diagnosis for the genus is presented; body shape, distribution and form of setae and number of pleural sclerites are diagnostic characters for larvae of this genus. comparative notes with similar larvae of other elmidae genera are presented. the existing generic keys are updated to include larvae of Stenhelmoides. comments on distribution and habitat of Stenhelmoides larvae are also provided. This work contributes to enhance the knowledge of Neotropical larvae, which have have been described for only approximately 56% of genera and 8% of species of Elmidae.

Do small cities affect bird assemblages? An evaluation from Patagonia Gorosito, Cristian Andrés; Cueto, Víctor Most studies about the impact of urbanization on bird assemblages are from the Northern Hemisphere and most previous research has reported that cities reduced bird species richness and favored the settlement of exotic bird species. However, most of these studies took place in large cities and few of them were focused on riparian environments. The aim of our study was to investigate how richness and abundance of riparian birds change along the urban-rural gradient of Esquel, a small city in Patagonia. We established two rural riparian sites upstream, two urban riparian sites and two rural riparian sites downstream, and set up six point counts in each site. We counted birds twice (once in November 2013 and January 2014) and sampled vegetation coverage at each point count location. We used GLMMs to analyze data. Bird species richness decreased from rural to urban sites while bird abundance increased. Omnivores thrived in the city whereas insectivores and insectivore-frugivores were abundant in rural sites. Birds species richness was associated with plant species richness, while abundances of insectivores and insectivore-frugivores birds were related to shrub coverage and foliage height diversity. Our study highlighted that small cities can modify bird communities in the same way as large cities, thus policies for conservation of birds should be created to coincide with urbanizations. We recommend planting native species in all urban green spaces and informing citizens about the benefits of this action. If everybody collaborates, conservation of native birds in developing areas of Andean Patagonia will be possible.

Hitting the wall: Human sperm velocity recovery under ultra-confined conditions Bettera Marcat, Matías Alejandro; Gallea, Maria Noel; Miño, Gastón Leonardo; Cubilla, Marisa Angelica; Banchio, Adolfo Javier; Giojalas, Laura Cecilia; Marconi, Veronica Iris; Guidobaldi, Héctor Alejandro Infertility is a common medical condition encountered by health systems throughout the world. Despite the development of complex in vitro fertilization techniques, only one-third of these procedures are successful. New lab-on-a-chip systems that focus on spermatozoa selection require a better understanding of sperm behavior under ultra-confined conditions in order to improve outcomes. Experimental studies combined with models and simulations allow the evaluation of the efficiency of different lab-on-a-chip devices during the design process. In this work, we provide experimental evidence of the dynamics of sperm interacting with a lateral wall in a shallow chamber. We observe a decrease in average sperm velocity during initial wall interaction and partial recovery after the alignment of the trajectory of the cell. To describe this phenomenon, we propose a simple model for the sperm alignment process with a single free parameter. By incorporating experimental motility characterization into the model, we achieve an accurate description of the average velocity behavior of the sperm population close to walls. These results will contribute to the design of more efficient lab-on-a-chip devices for the treatment of human infertility.

Metodología para el análisis de las prácticas y políticas de ordenamiento territorial en América Latina. El caso de Argentina, Ecuador, México y Paraguay; Methodology for the analysis of land use practices and policies in Latin America. The case of Argentina, Ecuador, Mexico and Paraguay Villagómez, Martha; Cuesta, Rosa; Sili, Marcelo Enrique; Vieyra, Antonio El presente artículo es producto de un proyecto de investigación cuyo objetivo principal fue presentar, sobre la base de experiencias de casos multiescalares (nacional, regional, rural y metropolitano), una metodología que permita conocer el estado de situación de las iniciativas de ordenamiento territorial en cuatro países de América Latina, señalando los principales factores que limitan o inhiben su puesta en marcha y sus resultados, de manera tal que se puedan plantear algunas pistas y recomendaciones para la mejora de las políticas y las prácticas de ordenamiento territorial en toda la región.; This article is the product of a research project whose main objective was to present, on the basis of experiences of multiscale cases (national, regional, rural and city), a methodology that allows us to know the status of territorial planning initiatives in four Latin American countries, pointing out the main factors that limit or inhibit its implementation and its results, so that some clues and recommendations can be raised for the improvement of land use policies and practices throughout the region.The study was executed between 2017 and 2018, within the technical assistance projects (PAT) sponsored by the Pan American Institute of Geography and History (PAIGH) that is dependent on the Organization of American States (OAS) and had the participation of the Military Geographic Institute of Ecuador, the National Autonomous University of Mexico through the Environmental Geography Research Center (CIGA) of the Morelia Campus, the Development Research Center of Paraguay and the National University of the South through the ADETER Center (Territorial Action and Development) of Argentina. To this was added the support of numerous researchers from other universities and research centers in the countries involved. In this research framework, the strategy included field work through interviews with important actors and knowledgeable about the problem. In addition, secondary information was collected from the official sources of each nation, based on all these instruments several workshops and discussions were held that allowed to obtain several products.The result of the investigation recognized common problems around the territorial planning present in the four countries analyzed, and which are also manifested at all scalar levels; Subsequently, based on these common themes for all, based on the methodological instruments developed and the expert criteria of the participants, proposals were generated that provide practical ideas in order to improve territorial planning policies in Latin America.

Comparative analysis of the biosimilar and innovative G-CSF modulated pathways on umbilical cord blood–derived mononuclear cells Ávila Portillo, Luz Mabel; Aristizabal, F.; Perdomo, S.; Riveros, A.; Ospino, B.; Avila, J. P.; Butti, M.; Abba, Martín Carlos Biosimilars of granulocyte colony-stimulating factor (G-CSF) have been routinely introduced into clinical practice. However, not functional genomics characterization has been performed yet in comparison with the innovator G-CSF. This study aimed to evaluate the transcriptomic changes in an in vitro model of umbilical cord blood cells (UBC) exposed to G-CSF for the identification of their modulated pathways. Umbilical cord blood cells–derived mononuclear cells (MNCs) were treated with biosimilar and innovator G-CSF for further gene expression profiling analysis using a microarray-based platform. Comparative analysis of biosimilar and innovator G-CSF gene expression signatures allowed us to identify the most commonly modulated pathways by both drugs. In brief, we observed predominantly upmodulation of transcripts related to PI3K-Akt, NF-kappaB, and tumor necrosis factor (TNF) signaling pathways as well as transcripts related to negative regulation of apoptotic process among others. In addition, hematopoietic colony-forming cell assays corroborate the G-CSF phenotypic effects over UBC-derived MNCs. In conclusion, our study suggests that G-CSF impacts UBC-derived cells through the modulation of several signaling pathways associated with cell survival, migration, and proliferation. The concordance observed between biosimilar and innovator G-CSF emphasizes their similarity in regards to their specificity and biological responses.

Landscape and drainage evolution during the Cenozoic in the Salinas Grandes Basin, Andean Plateau of NW Argentina López Steinmetz, Romina Lucrecia; Avila, Pilar; Davila, Federico Miguel Endorheic basins are distinctive features of the modern Andean plateau. These basins record thick Neogene-to-Modern evaporite successions that are considered as the onset of internal drainage and aridity. Some isolated older (Paleogene) evaporites and intermontane depocenters have been also described across the Argentine Puna, suggesting that some degree of hydrological isolation would have pre-dated the main Miocene-Pliocene plateau uplift. Evaporites beds, however, are not conclusive evidence for endorheism, given that their formation depends not only on the tectonically-driven paleo-drainage, but also on other sensitive variables as climate, and salinity of the sources. Here, we discuss the paleo-drainage evolution across the eastern Puna plateau at 23°-24° S, combining landscape numerical modeling with seismic stratigraphy. Seismic observations suggest an intermontane configuration as early as the late Paleogene, and relief formation to the east and west basin margins. Using different combinations of precipitation rates, our landscape models allowed us to reproduce the modern elevations observed in the study region as well as published thermochronological data. Our results suggest that endorheism would have started in the Paleogene, and would have dominated most (>70%) of the Cenozoic basin history. Models show the recurrence of endorheism, interrupted by intermittent phases of drainage connectivity (exorheism) to the east (foreland) in the upper half Eocene and the early Miocene. According to these results, the formation of closed basins in the Puna region would have pre-dated the main Miocene-Pliocene uplift stage of the Andean plateau.

Exact and heuristic approaches for multi-objective garbage accumulation points location in real scenarios Rossit, Diego Gabriel; Toutouh, Jamal; Nesmachnow, Sergio Municipal solid waste management is a major challenge for nowadays urban societies, because it accounts for a large proportion of public budget and, when mishandled, it can lead to environmental and social problems. This work focuses on the problem of locating waste bins in an urban area, which is considered to have a strong influence in the overall efficiency of the reverse logistic chain. This article contributes with an exact multiobjective approach to solve the waste bin location in which the optimization criteria that are considered are: the accessibility to the system (as quality of service measure), the investment cost, and the required frequency of waste removal from the bins (as a proxy of the posterior routing costs). In this approach, different methods to obtain the objectives ideal and nadir values over the Pareto front are proposed and compared. Then, a family of heuristic methods based on the PageRank algorithm is proposed which aims to optimize the accessibility to the system, the amount of collected waste and the installation cost. The experimental evaluation was performed on real-world scenarios of the cities of Montevideo, Uruguay, and Bahía Blanca, Argentina. The obtained results show the competitiveness of the proposed approaches for constructing a set of candidate solutions that considers the different trade-offs between the optimization criteria.

Las Lecciones de Derecho Constitucional de Florentino González en la Universidad de Buenos Aires (1869-1874): Diseños políticos nacionales y circulación trasnacional de doctrinas en la construcción de los estados sudamericanos; Florentino González Lectures on Constitutional Law at the University of Buenos Aires (1869-1874): National political designs and transnational circulation of doctrines in South America during State- Formation. Cucchi, Laura Este trabajo analiza los itinerarios intelectuales del colombiano Florentino González y de sus Lecciones de Derecho Constitucional impartidas en la Universidad de Buenos Aires, entre 1869 y 1874, con el objetivo de indagar las formas que adquirieron en esos años la traducción y adaptación crítica de diferentes facetas de la doctrina constitucional de los Estados Unidos en la Argentina. Examina, además, la difusión de las Lecciones en otros países del sur del continente, combinando un análisis histórico situado en un caso nacional, con un enfoque atento a las interconexiones transnacionales.; This paper analyzes the intellectual biography of the Colombian Florentino González and his Lectures on Constitutional Law at the University of Buenos Aires, between 1869 and 1874. It aims to explain one of the many ways in which the translation and critical adaptation of US Constitutional Law took place in Argentina. It also examines the dissemination of the Lectures in other south American countries during those years, combining a historical analysis located in a national case, with a focus on transnational interconnections.

Poeta que es y se dice mujer: las tensiones entre los géneros en la poética de Marina Mariasch; Poet who is and says woman: the tensions between the genres in the poetics of Marina Mariasch Mallol, Anahí Diana El trabajo analiza el modo en que, a principios del siglo XXI, la poeta Marina Mariasch, explora la redistribución de estereotipos, máscaras, roles y síntomas, de una subjetividad femenina, tanto en su narrativa como en los poemas. Para Mariasch la ficción normativa de género creada por los discursos sociales difiere de la experiencia del sujeto, y los textos dan cuenta del desgarro que se produce en la subjetividad de una mujer en las distintas etapas de la vida. Así, su escritura poética marca el borde dentado de las relaciones sexo/género, y alza una voz disidente que obliga a repensar el heteropatriarcado, poniendo de manifiesto diversos matices en la larga cadena de violencias y contradicciones que sufren los sujetos de la sociedad actual.; The paper analyzes the way in which, at the beginning of the 21st century, the poet Marina Mariasch, explores the redistribution of stereotypes, masks, roles and symptoms, of a feminine subjectivity, both in its narrative and in the poems. For Mariasch, the normative fiction of gender created by social discourses differs from the experience of the subject, and the texts give an account of the tear that occurs in the subjectivity of a woman in the different stages of life. Thus, his poetic writing marks the jagged edge of sex / gender relations, and raises a dissident voice that forces us to rethink the heteropatriarchy, revealing different nuances in the long chain of violence and contradictions suffered by the subjects of today's society. The poetic writing of Marina Mariasch marks the jagged edge of sex / gender relations, and raises a dissident voice that forces us to rethink the heteropatriarchy, giving an account of the nuances in the long chain of violence and contradictions that suffer the subjects of the current society.

To this end, asubset of tools from UML is used in an intuitive and orderedway starting with an informal description of the system untilimplementation details are obtained. However, the codificationof the system is left out as the programming language dependson the hardware platform to be used. The method has beenused in grade courses for several years now with an importantaccumulated experience that shows how students are able toadopt it and learn to elicit the different types of requirements,actors and functions.

Skull ontogeny of the pronghorn (Antilocapra americana) in the comparative context of native North American ungulates Moyano, Silvana Rocio; Morales, Miriam Mariana; Giannini, Norberto Pedro The pronghorn (Antilocapra americana (Ord, 1815)) is the single survivor of a largely extinct, isolated pecoran lineage (Antilocapridae) native to North America. We describe postnatal ontogeny of its skull in a comparative framework inclusive of representatives of other typical North American ungulate linages, all of which partially overlap in geographic distribution and share habitat with A. americana. To describe allometric growth, we took 23 linear cranial measurements in 30 specimens of A. americana and applied bi-and multi-variate statistics. The skull of A. americana generally grew with negative rates in width and height dimensions, and with positive rates in length, including an elongation of rostrum, particularly the nasals, and a relative narrowing of the braincase. We compared skull development in A. americana with development in two cervids (white-tailed deer (Odocoileus virginianus (Zimmermann, 1780)) and wapiti (Cervus canadensis Erxleben, 1777)) and two bovids (bighorn sheep (Ovis canadensis Shaw, 1804) and American bison (Bison bison (Linnaeus, 1758))). The multivariate ontogenetic trajectory of A. americana overlapped greatly with that of Odocoileus virginianus, and differed from the other species in varying degrees. These results indicated an essentially convergent pattern of skull growth with species showing important functional similarities, such as cervids of comparable size and feeding habits.

Strong multiplicity one theorems for locally homogeneous spaces of compact type Lauret, Emilio Agustin; Miatello, Roberto Jorge Let G be a compact connected semisimple Lie group, let K be a closed subgroup of G, let Γ be a finite subgroup of G, and let τ be a finitedimensional representation of K. For π in the unitary dual G of G, denote by nΓ(π) its multiplicity in L2(Γ\G). We prove a strong multiplicity one theorem in the spirit of Bhagwat and Rajan, for the nΓ(π) for π in the set Gτ of irreducible τ-spherical representations of G. More precisely, for Γ and Γ finite subgroups of G, we prove that if nΓ(π) = nΓ (π) for all but finitely many π ∈ Gτ , then Γ and Γ are τ-representation equivalent, that is, nΓ(π) = nΓ (π) for all π ∈ Gτ . Moreover, when Gτ can be written as a finite union of strings of representations, we prove a finite version of the above result. For any finite subset Fτ of Gτ verifying some mild conditions, the values of the nΓ(π) for π ∈ Fτ determine the nΓ(π)’s for all π ∈ Gτ . In particular, for two finite subgroups Γ and Γ of G, if nΓ(π) = nΓ (π) for all π ∈ Fτ , then the equality holds for every π ∈ Gτ . We use algebraic methods involving generating functions and some facts from the representation theory of G.

The structure and migration patterns of the population of Uruguay through isonymy Carrieri, A.; Sans, M.; Dipierri, Jose Edgardo; Alfaro Gómez, Emma Laura; Mamolini, E.; Sandri, M.; Rodríguez Larralde, A.; Scapoli, C.; Barrai, I. Surname distribution can be a useful tool for studying the genetic structure of a human population. In South America, the Uruguay population has traditionally been considered to be of European ancestry, despite its trihybrid origin, as proved through genetics. The aim of this study was to investigate the structure of the Uruguayan population, resulting from population movements and surname drift in the country. The distribution of the surnames of 2,501,774 people on the electoral register was studied in the nineteen departments of Uruguay. Multivariate approaches were used to estimate isonymic parameters. Isolation by Distance was measured by correlating isonymic and geographic distances. In the study sample, the most frequent surnames were consistently Spanish, reflecting the fact that the first immigration waves occurred before Uruguayan independence. Only a few surnames of Native origin were recorded. The effective surname number (α) for the entire country was 302, and the average for departments was 235.8 ± 19. Inbreeding estimates were lower in the south-west of the country and in the densely populated Montevideo area. Isonymic distances between departments were significantly correlated with linear geographic distance (p < 0.001) indicating continuously increasing surname distances up to 400 km. Surnames form clusters related to geographic regions affected by different historical processes. The isonymic structure of Uruguay shows a radiation towards the east and north, with short-range migration playing a major role, while the contribution of drift, considering the small variance of α, appears to be minor.

The Pliocene canid Cerdocyon avius was not the type of fox that we thought Ruiz Ramoni, Damián; Prevosti, Francisco Juan; Lucenti, Saverio Bartolini; Montellano Ballesteros, Marisol; Carreño, Ana Luisa During the 1980s, a Pliocene canid from Baja California Sur, Mexico, was described as a new Cerdocyon species, C. avius. Whereas some investigators believe that C. avius was related to the origin of South American foxes of the tribe Cerdocyonina, others suggested that it is related to members of the tribe Vulpini. Our observations and analyses confirm that it is a vulpine with a morphological combination of features that has not been described previously: marked subangular lobe in the hemimandible, m1 hypoconulid is practically absent, and the m3 is single-cusped. We propose Ferrucyon, gen. nov., as a genus including at present one species, F. avius. In the phylogenetic analysis, this species is related to North American Metalopex macconnelli, and to the Eurasian Nyctereutes spp., which creates a relationship between the foxes of the Old and New World.

Measurement of soft-drop jet observables in p p collisions with the ATLAS detector at s = 13TeV Aad, G.; Abbott, B.; Abbott, D. C.; Abed Abud, A.; Abeling, K.; Abhayasinghe, D. K.; Abidi, S. H.; AbouZeid, O. S.; Abraham, N. L.; Abramowicz ,H.; Abreu, H.; Abulaiti, Y.; Acharya, B. S.; Achkar, B.; Adachi,S.; Adam, L.; Adam Bourdarios, C.; Adamczyk, L.; Adamek, L.; Adelman, J.; Adersberger, M.; Adiguzel, A.; Adorni, S.; Adye, T.; Affolder, A. A.; Afik, Y.; Agapopoulou, C.; Agaras, M. N.; Aggarwal, A.; Piegaia, Ricardo Nestor Jet substructure quantities are measured using jets groomed with the soft-drop grooming procedure in dijet events from 32.9 fb−1 of pp collisions collected with the ATLAS detector at s=13 TeV. These observables are sensitive to a wide range of QCD phenomena. Some observables, such as the jet mass and opening angle between the two subjets which pass the soft-drop condition, can be described by a high-order (resummed) series in the strong coupling constant αS. Other observables, such as the momentum sharing between the two subjets, are nearly independent of αS. These observables can be constructed using all interacting particles or using only charged particles reconstructed in the inner tracking detectors. Track-based versions of these observables are not collinear safe, but are measured more precisely, and universal non-perturbative functions can absorb the collinear singularities. The unfolded data are directly compared with QCD calculations and hadron-level Monte Carlo simulations. The measurements are performed in different pseudorapidity regions, which are then used to extract quark and gluon jet shapes using the predicted quark and gluon fractions in each region. All of the parton shower and analytical calculations provide an excellent description of the data in most regions of phase space.

Determination of safe storage moisture content of soybean expeller by means of sorption isotherms and product respiration Maciel, Gisele; de la Torre, Diego Antonio; Cardoso, Leandro Marcelo; Cendoya, María Gabriela; Wagner, Jorge Ricardo; Bartosik, Ricardo Soybean expeller (SBE) is rich in protein and has a relatively high and variable oil composition (7–15%). With the increasing use of the SBE for animal nutrition there arose a need for understanding the quality deterioration during storage. The goal of this research was to determine the storability of SBE by developing a model for predicting its equilibrium moisture content (EMC), using the EMC model to determine its safe storage moisture content (SSMC), and by measuring dry matter loss (DML) for SBE incubated at 10 °C and 20 °C for 46 days. Samples of SBE with different residual oil contents were collected and an EMC experiment was carried out to determine the sorption isotherms at 65, 70, 75 and 80% RH; at 10 and 20 °C for samples with 6.2, 9.6 and 15.3% oil content. A second set of samples was used for determining the respiration rate at 20 °C. The Enhanced Halsey model was fitted to the SBE EMC/equilibrium relative humidity (ERH) data and it was established that the residual oil content significantly affected the sorption isotherms. By considering an ERH of 67% or below to be a safe storage condition, the SBE should be stored at or below 12.2% moisture content (m.c.) if the temperature is at or below 20 °C and an the oil content is 7%. However, according to the respiration experiments it would be safe to store SBE up to 16% m.c. (equivalent to 75% ERH). Considering a DML limit of 0.1%, the allowable storage time of SBE at a m.c. lower than 15.4% (ERH of 75%) was at least 46 days. The widely accepted practice of incorporating the gums present in the extracted oil, diluted in water, back into the SBE should be avoided since it increases the m.c. of the product and substantially reduces the allowable storage time.

Reformulating the tourism-extended environmental Kuznets curve: A quantile regression analysis under environmental legal conditions Porto, Natalia; Ciaschi, Matías Omar This work aims to empirically study the environmental Kuznets curve (EKC) in a model that takes into account the tourism sector. We use two novel approaches in this framework: an own developed environmental legal index and an instrumental quantile regression methodology. Our study comprises 18 Latin American countries between 1995 and 2013. We have found that tourism activity causes carbon emissions increases but, because of the restrictions imposed by environmental regulations, further tourism activity can mitigate these adverse environmental effects, mainly in high-polluted countries. These results suggest a step forward in the tourism-extended EKC estimations: they indicate the need for analysis considering the heterogeneities in environmental conditions across countries and the role of environmental regulation within this framework.
