Published: November 2021

Purpose: This study investigated the correlations of hemodynamic parameters measured to quantify stenosis between the gold-standard duplex ultrasonography and the dual-gate Doppler mode.Methods: Patients examined due to suspicion of carotid artery stenosis or for surveillance of known stenosis were invited to participate in this prospective single-center study. Upon acceptance, the hemodynamic characteristics of the carotid arteries were determined successively in standard duplex and dual-gate Doppler modes. The correlations between the two modes were analyzed by computing Pearson coefficients (r2) and Lin concordance coefficients (ρc). The degree of agreement between the two methods was visualized using Bland-Altman graphical representations.Results: The correlation between internal carotid artery peak systolic velocity measured by standard duplex ultrasonography and dual-gate Doppler mode was good (r2=0.642). The same high level of correlation was observed for the carotid ratio (r2=0.544). However, the Bland-Altman graphical representation and the Lin concordance coefficients (ρc=0.75 and ρc=0.74 for the internal carotid artery peak systolic velocity and carotid ratio, respectively) showed that a lack of precision generated some discrepancies between the two measurement methods.Conclusion: Although some discrepancies were observed, the hemodynamic measurements were closely correlated between the two ultrasonography modes. Therefore, the dual-gate Doppler mode may have obvious advantages over conventional ultrasonography, offering interesting development possibilities.
O indisciplinado patológico em Augusto Cury
Authors: Gonçalves Machado Dimitrius
Published: November 2021

Este artigo tem como objetivo analisar o transbordamento da literatura de autoajuda na Educação e compreender, a partir de obras do Augusto Cury, a discursividade que circula e produz uma categorização do indivíduo indisciplinado na escola atual. Para esta análise, me alio aos estudos foucaultianos e busco por relações de saber e poder que conduzam a práticas de divisão ao categorizar certos indivíduos como indisciplinados e não outros, bem como as redes discursivas que sustentam a atualização deste modo de visibilidade. Focalizando as discursividades presentes nas obras de Cury pude elaborar o eixo de análise, que apresenta maneiras de compreender distúrbios da mente, como central para a categorização: o indisciplinado patológico. Com esse eixo produzi três divisões argumentativas: Causas, Gestão e resolução e Características. Assim, o indisciplinado patológico é produzido por enunciações que o reconhecem a partir de características de distúrbios da mente e das condutas, Síndrome do Pensamento Acelerado, excesso de cansaço, irritabilidade, ansiedade, fadiga e informações além da capacidade de processamento cerebral. A causa é uma sociedade patologizante, uma sociedade que produz doenças. A solução são ações educativas que ensinem cada um a cuidar de si mesmos, uma individualização e divisão de si e do fora. Uma necessidade de gestão de si mesmo com ferramentas vistas como adequadas, é com elas que os educadores precisam, então, estar atentos ao olhar que examina, percebe e dispõe as ferramentas corretas para a autogestão da mente e das emoções. Desse modo, busco contribuir tanto para as discussões sobre a proliferação da autoajuda na Educação quanto propondo elementos que ajudem a desnaturalizar o modo que se categoriza um indivíduo como indisciplinado.

The objective of this work was to evaluate the antioxidant and antimicrobial capacity of Kale leaves, as well as to quantify the levels of phenolic compounds and flavonoids present in its aqueous extract, and the viability when added to a fermented milk drink. The leaves were subjected to four treatments: fresh crushed in a blender, fresh sprayed with liquid nitrogen, dried in an oven at 45°C for 72 hours and frozen. Antioxidant activity, concentration of total phenolic compounds, flavonoids and antimicrobial activity were determined. To prepare the dairy drink, the amounts of 5%, 10% and 15% of the dry extract of Kale leaves were added, as well as 15% of the dry extract with sorbate and the control treatment. Furthermore, it determined the antioxidant activity and the number of lactic acid bacteria in the drink. The dried and frozen leaves showed better antioxidant activity and, when compared to fresh powdered leaves, they did not differ in phenolic compounds, presenting the best contents. Fresh powdered leaves showed the highest flavonoid yield. The aqueous extracts of kale leaves did not show antibacterial activity against the studied microorganisms. The abstract did not show antioxidant capacity contents of total phenolic compounds and flavonoids in kale subjected to different treatments.

Esta pesquisa teve como objetivo caracterizar o lodo de uma Estação de Tratamento de Água (ETA) de uma cidade costeira e tropical do nordeste brasileiro. Os parâmetros físico-químicos (cor, pH, turbidez, sólidos totais e sedimentáveis, demanda química de oxigênio e alumínio total), análises microbiológicas (coliformes termotolerantes) e ecotoxicológicas (semente de alface - Lactuca sativa) e do microcrustáceo marinho (Mysidopsis juniae) foram analisados em amostras de lodo do decantador e da água de lavagem dos filtros. Como esperado, o lodo do decantador apresentou maior quantidade de sólidos do que o filtro, mas, apesar disso, a concentração total de sólidos no filtro ultrapassou 86 vezes o limite para ser despejado nos corpos hídricos, segundo as diretrizes brasileiras. Além disso, as concentrações de alumínio estavam acima das diretrizes para água doce (910% - lodo do decantador e 210% - lodo do filtro). Em relação à ecotoxicidade, o lodo de ambos os estágios não afetou a germinação das sementes e ainda promoveu o crescimento de 30 a 60% das radículas. Por outro lado, o lodo do decantador mostrou-se significativamente tóxico para microcrustáceos em concentrações acima de 15%. Considerando que esses lodos podem ser lançados diretamente no rio em zona estuarina, destaca-se seu potencial de toxicidade ao meio aquático e a importância do tratamento adequado antes de sua disposição final.

Societal Constitutionalism: Background, Theory, Debates
Authors: Golia Angelo Jr , Teubner Gunther
Published: November 2021

The article provides a systematic outline and refinement of societal constitutionalism (SC), one of the frameworks emerged in contemporary legal theory to analyse constitutional phenomena. After an introduction in Section 1, Section 2 summarises SC’s theoretical background, namely the debates on the Economic Constitution (2.1), legal pluralism (2.2), systems theory (2.3), and the work of David Sciulli (2.4). Section 3 explains SC’s analytical limb, which on the one hand criticises some tenets of state-centred constitutionalism (3.1); and on the other hand identifies functions, arenas, processes, and structures of a constitutionalised social system (3.2). Section 4 turns to SC’s normative limb, pointing to some constitutional strategies that increase social systems’ capacities of self-limitation (4.1); and develop a law of inter-constitutional collisions (4.2). Section 5 addresses the main competing approaches and criticisms, which are based on state-centred constitutionalism (5.1); on international/global constitutionalism (5.2); and on contestatory/material constitutionalism (5.3).
A Review on the Material Development and Corresponding Properties for Power Plant Applications
Authors: Patil Jeet P. , Paliwal Manas , Mishra Sushil K.
Published: November 2021

Over the past decade, increased demand for energy generation at affordable rates and in a clean state has been the driving force for material development for energy generation. In developing countries, coal-fired thermal power plants are the major source of electricity generation. However, coal-fired plants induce a higher carbon footprint and contribute to greenhouse gas emissions. Hence, several strategies have been formulated to mitigate environmental pollution while maintaining high energy output. This review comprehensively presents the historical material development process that led to an increase in the efficiency of a coal-fired power plant. Candidate material identification and application, essential alloying elements, and their impact on service life are comprehensively reviewed. Adapting the ultra-supercritical (USC) and advanced ultra-supercritical (A-USC) power generation technology requires the development of new alloys that can withstand harsh operating conditions (700–725°C and 25–35 MPa), which demands the replacement of conventional materials (ferritic/austenitic steel) with better ones. The candidate alloys should be evaluated across several key issues such as high-temperature material response to loading, creep strength, high-temperature oxidation, and component fabricability. The evaluation of creep strength data suggests that nickel-based alloys like Inconel alloy 282 are preferred because of the high stability of the γ′ phase. Moreover, at higher temperatures, nickel-based alloys are preferred over ferritic/austenitic steel alloys because of their superior corrosion resistance. The fireside corrosion and high-temperature oxidation resistance are governed by the formation of different oxide layers depending on the temperature, pressure, and alloy content. Furthermore, the weldability of different candidate alloys is discussed in detail, along with the microstructural evolution in the heat-affected zone. This review also focuses on the cost of constructing a greenfield USC/A-USC power plant. Lastly, a perspective on new alloy development for A-USC/USC application is presented, and the microstructure and property relationships of these alloys are discussed.

The G2019S mutation in leucine-rich repeat kinase 2 (LRRK2) causes familial Parkinson’s disease (PD) and is also found in a subset of idiopathic cases. Prior studies inDrosophilaand human induced pluripotent stem cell (iPSC)-derived dopamine neurons uncovered a pronounced effect of G2019S LRRK2 on mRNA translation. It was previously reported that G2019S LRRK2 promotes translation of mRNAs with complex 5′ untranslated region (UTR) secondary structure, resulting in increased expression of calcium channels and dysregulated calcium homeostasis in human dopamine neurons. Here, we show that dysregulated translation occurs in the brains of mammalian LRRK2 modelsin vivo. Through ribosome profiling studies of global translation, we observe that mRNAs with complex 5′UTR structure are also preferentially translated in the G2019S LRRK2-expressing mouse brain. Reporter assays suggest that this 5′UTR preference is independent of translation initiation factors. Conversely, translation of mRNAs with complex 5′UTR secondary structure is downregulated in LRRK2 knock-out (KO) mouse brain, indicating a robust link between LRRK2 kinase activity and translation of mRNA with complex 5′UTR structure. Further, substantia nigra pars compacta (SNpc) dopamine neurons in the G2019S LRRK2-expressing brain exhibit increased calcium influx, which is consistent with the previous report from human dopamine neurons. These results collectively suggest that LRRK2 plays a mechanistic role in translational regulation, and the G2019S mutation in LRRK2 causes translational defects leading to calcium dysregulation in the mammalian brain.
Silent Synapses in Cocaine-Associated Memory and Beyond
Authors: Wright William J. , Dong Yan
Published: November 2021

Glutamatergic synapses are key cellular sites where cocaine experience creates memory traces that subsequently promote cocaine craving and seeking. In addition to making across-the-board synaptic adaptations, cocaine experience also generates a discrete population of new synapses that selectively encode cocaine memories. These new synapses are glutamatergic synapses that lack functionally stable AMPARs, often referred to as AMPAR-silent synapses or, simply, silent synapses. They are generatedde novoin the NAc by cocaine experience. After drug withdrawal, some of these synapses mature by recruiting AMPARs, contributing to the consolidation of cocaine-associated memory. After cue-induced retrieval of cocaine memories, matured silent synapses alternate between two dynamic states (AMPAR-absent vs AMPAR-containing) that correspond with the behavioral manifestations of destabilization and reconsolidation of these memories. Here, we review the molecular mechanisms underlying silent synapse dynamics during behavior, discuss their contributions to circuit remodeling, and analyze their role in cocaine-memory-driven behaviors. We also propose several mechanisms through which silent synapses can form neuronal ensembles as well as cross-region circuit engrams for cocaine-specific behaviors. These perspectives lead to our hypothesis that cocaine-generated silent synapses stand as a distinct set of synaptic substrates encoding key aspects of cocaine memory that drive cocaine relapse.
Pets and Politics: Do Liberals and Conservatives Differ in Their Preferences for Cats Versus Dogs?
Authors: Ivanski Chantelle , Lo Ronda F. , Mar Raymond A.
Published: November 2021

Liberals and conservatives are perceived to disagree on most aspects of life, even seemingly trivial things like pet choice. Although the question of whether liberals and conservatives differ in their liking for cats and dogs has been sporadically investigated, few peer-reviewed reports exist, results are mixed, and most reports examine this topic indirectly. In this registered report we employed a large existing dataset to examine whether political identity predicts liking of cats and dogs, and a preference for one over the other. Self-reported political identity was used to predict explicit evaluations of both pets, in addition to performance on an Implicit Association Test (IAT) measuring pet preference. Greater conservativism predicted more negative evaluations of cats and an overall preference for dogs over cats, even after controlling for relevant demographics.
γENaC/CD9 in urinary extracellular vesicles as a potential biomarker of MR activity
Authors: Hayakawa Tomoaki , Fukuhara Atsunori , Saiki Aya , Otsuki Michio , Shimomura Iichiro
Published: November 2021

Primary aldosteronism (PA) is caused by autonomous overproduction of aldosterone, which induces organ damage directly via activation of the mineralocorticoid receptor (MR); however, no specific or sensitive biomarkers are able to reflect MR activity. Recently, it is found that urinary extracellular vesicles (uEVs) are secreted by multiple cell types in the kidney and are an enriched source of kidney-specific proteins. Here, we evaluate sodium transporters in uEVs as candidates of biomarkers of MR activity in the clinical setting. Sixteen patients were examined to determine their plasma aldosterone concentration (PAC) and renin activity, and their morning urine was collected. The protein levels of two sodium transporters in uEVs, γ-epithelial sodium channel (γENaC) and thiazide-sensitive sodium chloride cotransporter (NCC), were quantified by Western blot analysis, and their clinical correlation with PAC was determined. Consequently, we found PAC was significantly correlated with the γENaC protein level adjusted by the CD9 protein level in uEVs (correlation coefficient = 0.71). PAC was also correlated with the NCC protein level adjusted by the CD9 protein level in uEVs (correlation coefficient = 0.61). In two PA patients, treatment with an MR antagonist or adrenalectomy reduced γENaC/CD9 in uEVs. In conclusion, γENaC/CD9 in uEVs is a valuable biomarker of MR activity in PA patients and may be a useful biomarker for other MR-associated diseases.
Repensando el modelo de “Desarrollo Sostenible”. De la competitividad a la cooperación
Authors: Torres Rojas José Eduardo
Published: November 2021

El actual modelo de desarrollo, basado en la idea de un crecimiento económico con el único propósito de potenciar la creación de “puestos de trabajo”, e incentivar el consumo, olvidando las fronteras de los límites de producción y el hecho de que es imposible un crecimiento infinito, en un planeta con recursos limitados, debe ser repensado en pro de ajustarlo a una realidad innegable. Se proponen por tanto un cambio de paradigma y guías de trabajo, basados en el conocimiento previo y la toma de conciencia de la sumatoria de problemas creados por el actual sistema de producción y consumo. Un claro desfase de escala que nos ha llevado a crear una tecnosfera que no encaja con la biosfera, unido a una ineficiencia manifiesta en lo producido y una fe extrema puesta en la tecnología como solución a la problemática medioambiental, social y económica, desconociendo para ello el principal departamento de I+D+I que representa la naturaleza, que nos provee además de las soluciones a la inmensa mayoría de desafíos. Desafíos que, gracias al antropocentrismo, creemos solucionar con nuestros propios diseños. Se hace así prioritario un cambio de enfoque, con una visión eco sistémica y holística, basada en una retoma de la ética y los valores, donde se clarifica que no necesariamente el crecimiento debe asociarse a crecimiento económico y mucho menos pensar que la revaluación del modelo conlleva a una pérdida de calidad de vida.

Authors: Gu Wenhui , Wang Guangce
Published: November 2021

The concentrates of coking effluents are toxic and technically challenging to treat. Environmental protection demands an efficient and cost-effective technique for coking wastewater treatment. The intertidal marine macro alga Ulva prolifera has a high tolerance to various environmental stresses. In this study, U. prolifera was collected from an intertidal field and tested in a laboratory-scale photobioreactor for potential bioremediation of coking effluent concentrate. Algal physiology and water quality were measured. During treatment, the quantum yield Fv/Fm and effective quantum yield Y(II) values showed 12% and 15% decreases in 24 h, respectively, and a complete recovery in 168 h. The algal physiological characteristics indicated that light irradiance provided in a sine pattern of enhanced algal growth by 53% in the coking concentrate. The removal efficiency for total nitrogen and total phosphorus was up to 26.1% and 68.5% in 24 h, respectively. It also showed high removal efficiencies for some heavy metals, chemical oxygen demand, biological oxygen demand, and nutrients within 24 h. The feasibility of using U. prolifera for coking concentrate treatment was also considered. This study provided a possible bioremediation technique for wastewater treatment, especially for concentrates of coking effluent, in the coking industry.

Psammophis indochinensis Smith, 1943 was reported in the eastern Java and Bali of Indonesia despite its primary geographic range being in the Indochina region. We confirm its presence in Bali based on a newly collected specimen and provide morphological and genetic data. The specimen was found in a lowland, urban areas near open grassland habitat, which confirms the distribution of P. indochinensis along the northern coast of Bali. We note some character aberrations in the supralabials compared to Thailand specimens, suggesting an extended character. The basal clade position of P. indochinensis raises the possibility of an intercontinental dispersal scenario of this African-origin snake.
PHENOTYPIC AND GENETIC PARAMETERS ESTIMATED FOR FRESH CORN UNDER DIFFERENT NUTRIENT AVAILABILITY1

Published: November 2021

ABSTRACT The objective of this work was to estimate and compare phenotypic and genetic parameters after three cycles of intrapopulation recurrent selection for fresh corn grown under three nutrient availability conditions. Three experiments derived from the same population (MV-003) were conducted to assess the ability of progenies to absorb nutrients, one under adequate fertilization (control; MV-006), one under low nitrogen availability (N; MV-006N), and one under low phosphorus availability (P; MV-006P). The experiments were carried out in randomized blocks, with 64 half-sib progenies and three replications for each nutritional condition. Chlorophyll index, plant height, ear insertion, ear diameter, ear length, unhusked ear yield, and marketable husked ear were evaluated. The populations showed variability for the three nutrient availability conditions. The variability reduced after only three selection cycles; thus, evaluating a higher number of half-sib progenies, above 64, under low N and P availability is indicated. The rates used to identify the most efficient progenies in breeding programs should be close to the appropriate one, with a slow reduction after the selection cycles. The variability will be thus maintained, with a greater possibility of identifying more promising progenies. In addition, the frequency of favorable alleles increases more gradually and effectively. The N and P rate of 60 kg ha-1 is not indicated as a critical level for the initial phase of the program.

Published: November 2021

ABSTRACT Vegetable intercropping systems use complementarity between species to increase agricultural profitability. This study evaluated the effects of intercropping chicory and arugula species with collard greens on crop yield and land use efficiency (LUE). Six treatments, consisting of species planted as monocultures or intercropped in various combinations, were evaluated in a randomized block design with four replicates. The cultivars ‘Top Bunch’ (collard greens), ‘Pão de Açúcar’ (chicory) and ‘Folha Larga’ (arugula) were used. The yield of collard greens in monoculture did not differ from those obtained when they were intercropped with chicory, arugula, or both species, whereas chicory and arugula yields were higher in monoculture. However, even with yield losses for chicory and arugula in intercropping, LUE indices were greater than 1.0 in all intercropping systems, indicating their viability. The highest LUE index (2.41) was obtained in the chicory-arugula-collard green intercropping system.

Published: November 2021

ABSTRACT To evaluate seed vigor, electrical conductivity and ethanol tests are fast and efficient methodologies. They have the potential to be used in several species, such as red rice. However, there are no protocols or information about their efficiency. Thus, the objective was to evaluate the efficiency, and define parameters of execution for electrical conductivity and ethanol tests, to evaluate the vigor of red rice seeds. The study was conducted using four lots of ‘BRS 901’ red rice, which was subjected to a germination test, as well as first count, accelerated aging, and field seedling emergence tests. The electrical conductivity test was performed with 25, 50, and 100 seeds soaked in 50 mL and 75 mL of water, at 25 °C and 30 °C, for 3, 6, 20, and 24 hours, respectively. The ethanol test was performed with 50 and 100 seeds soaked in a volume of water equivalent to 1.0, 1.5, 2.0, 2.5, and 3.0× the mass of the seed sample. To assess the vigor of red rice seeds, the electrical conductivity test is an efficient method when conducted with 50 seeds soaked in 50 mL of water at 25 °C for 20 hours. Meanwhile, the ethanol test is most effective when performed with 50 seeds, in a volume of water that is 2.5× the mass of the sample, at 40 °C for 24 hours.

ABSTRACT Corn, one of the main grain crops in Brazil, needs to have its nutritional requirements fully satisfied to achieve high biological productivity. Thus, the objective of this work was to evaluate the influence of increasing doses of poultry litter biochar on nutrient concentrations in the leaves of hybrid corn BRS 2022 and in the soil after harvest. The experiment was carried out in a completely randomized design, with four replicates, evaluating six doses of biochar (0; 2.02; 4.05; 6.07; 8.10 and 10.12 t ha-1) and the plots composed of one plant per pot with a volume of 20 dm3. The collection of leaves for leaf diagnosis was carried out at the time of flowering, removing the opposite leaf from the ear base in the middle third region. These leaves were dried in a forced air circulation oven, 65 °C, for a period of 48 hours, ground, sieved through 20 mesh and analyzed for the concentrations of macronutrients in the leaf tissue. At the end of the experiment, 83 days after corn sowing, soil samples were collected as a function of the treatments and then analyzed chemically. Biochar application promoted an increase in the leaf contents of N, P and K, resulting in improvements in the nutritional status of plants for these nutrients. The chemical characteristics of the soil, analyzed after the corn harvest, revealed that there was an influence of the doses of biochar on the levels of calcium, organic carbon, potassium and phosphorus.

ABSTRACT Previous investigations showed that diverse varieties of melon may have different attractiveness for bees. Therefore, the objective of this study was to evaluate the composition, frequency and behavior of flower visitors of some melon (Cucumis melo) cultivars (Amarelo, Pele de Sapo, Cantaloupe, Gália) in different conditions (conventional and organic farming, dry and rainy seasons, with and without mulching and introduction or not of honey bee hives) in the main production poles in the Brazilian Northeast (Petrolina-PE/Juazeiro-BA, Pacajus-CE and Mossoro-RN). Observations and collections of flower visitors occurred from 5p.m. to 6p.m, in non-consecutive days. We recorded 12 species of insects, mostly bees. The most frequent was Apis mellifera (99.68%), but other species appeared sporadically (less than 0.5%): Xylocopa grisescens, Trigona spinipes, Plebeia sp., Melipona mandacaia, Frieseomelitta doedereleini, Halicitidae. Apis mellifera was present in all studied cultivars and sites. Xylocopa grisescens appeared in two poles, but not in Pacajus-CE, Amarelo cultivar. In addition, Trigona spinipes, although present in the three poles, was not recorded on Pele de Sapo. The Amarelo cultivar, under organic farming, without the use of mulching, and presence of honey bee hives, in the Petrolina-PE/Juazeiro-BA pole, in the dry season, was the combination of factors showing the largest number of Apis mellifera as the main visitor of melon flowers.

A pandemia da Covid-19 e suas medidas de enfrentamento trouxeram pressões sobre a assistência social e previdenciária. Junto a isso estão os desafios de a informação estar dispersa, ser complexa, suscetível às distorções e uma sociedade com capacidades distintas de assimilação e análise. Este artigo tem o objetivo de apresentar a experiência do Observatório Covid-Prev como instrumento para a transparência e accountability na gestão pública da seguridade social e previdenciária em tempos de pandemia. Essa experiência com o observatório social abrangeu a escolha de temas e variáveis a serem divulgados e analisados, a estratégia de planejamento visual e de divulgação, bem como a discussão do papel e potencial do observatório. Assim, uma equipe multidisciplinar desenvolveu projeto visando analisar o impacto da Covid-19 no Sistema de Previdência Brasileiro, sob diferentes perspectivas, tanto com a reprodução de dados e informações como para elaboração de análises: impactos da pandemia no mercado de trabalho e seus efeitos sobre a evolução das receitas e despesas previdenciárias, efeitos da pandemia nos grupos vulneráveis, sustentabilidade dos fundos de pensão, impactos no mercado financeiro, entre outras. Essas informações foram divulgadas primeiramente na plataforma Blogger e depois em sítio eletrônico cuja divulgação foi feita tanto nas redes sociais dos próprios participantes da pesquisa como nas redes sociais de entidades interessadas no tema, como a Associação Brasileira de Instituições de Previdência Estaduais e Municipais (ABIPEM). Em seu curto período de existência o observatório ultrapassou 10 mil acessos, oriundos tanto do Brasil como de outros países. O observatório apresentou dados e análises de forma simples, com base em informações que se encontram dispersas e com níveis diferentes de complexidade. Nestas análises buscou-se estabelecer as relações entre fatos correlacionados à seguridade social e previdenciária. Desse modo, entende-se que o observatório colaborou como instrumento de transparência e accountability com relação ao tema da previdência no Brasil e serve como discussão dos desafios e potencialidades dos observatórios sociais.

Background: Populus luziarum and P. primaveralepensis are endemic species of western Mexico; growing in riparian forests they are critically endangered. The best way to conserve their seeds is unknown, which could be limiting for their conservation.
Hypothesis: The germinability of both subtropical species is like that of boreal and template Salicaceae species that disperse seeds in spring and early summer, as they germinate quickly with high percentages, and rapidly lose their viability when stored at ambient temperature.
Studied species: Populus luziarum and P. primaveralepensis.
Study site and dates: Western Trans-Mexican Volcanic Belt. Jalisco, Mexico. October 2019.
Methods: The physical integrity of the seeds was assessed by X-ray imaging and compared with germinability. In addition, the effect of storage time (nine weeks) under two temperatures (4 and 21 °C) on the percentage and mean germination rate was evaluated.
Results: No significant differences were found between physical integrity and germination in freshly collected seeds for both species. Germination in the first 24 hrs was 91 and 95 % for Populus luziarum and P. primaveralepensis, respectively (week 0). Germination percentages were lower when stored at 21 °C, but P. primaveralepensis was decreased more slowly.
Conclusions:  Seeds of subtropical Populus respond similarly to those of species from temperate and boreal climates with early seed dispersal, a crucial condition for establishing ex situ reforestation and conservation programs.
Caracterización in silico y análisis de la expresión expresión génica de proteínas abundantes en la embriogénesis tardía de Agave tequilana Weber var. azul

Published: November 2021

Background/ Studied species: Agave tequilana Weber var. azul is an important crop in Mexico, used for tequila production. Many species of Agave grow in arid lands and are highly tolerant to those environmental conditions. However, the molecular bases of mechanisms selected in agaves to face abiotic stress, have not been described.
Hypotheses: Late-embryogenesis abundant proteins (LEAPs), a superfamily closely associated to abiotic stress responses in plants, are a key element in agave responses to arid environments.
Methods: Transcriptomic data from A. tequilana were used to perform in silico analyses to identify genes encoding Agave LEAPs. We compare their structural characteristics and their similarity/divergence with described LEAPs from other plant species using bioinformatics. The abundance of the AteqLEAP transcripts in vegetative organs and in response to high temperatures was determined by qRT-PCR.
Results: We identified three structurally different AteqLEAPs. AteqLEA_5Bs show low similarity to LEAPs known as “atypical” (containing LEA_3 domain); and they exhibit an unexpected high and constitutive expression pattern in leaves. But AteqLEA_5C (LEA_2) transcripts are low-expressed in all the organs analyzed. Two isoforms of AteqDHN type SK3 show the typical structural disorder and hydrophilicity of dehydrins and are highly expressed in undeveloped leaves, vegetative meristem and stem.
Conclusions: AteqLEAP_5Bs seem to play a major and preventive protective role in fully photosynthetic leaves as in a “primed state”; whereas AteqDHNs presumably play a role protecting tissues in differentiation stage as meristem and developing leaves, and storage tissues such as the agave stem.
Convergence and nuances of Net Neutrality in South America
Authors: Triviño Roberto D. , Franco-Crespo Antonio , Ochoa-Urrego Leonardo
Published: November 2021

The Internet has become the ultimate platform for convergence, closely associated with network, technology, and media, due to its open and nondiscriminatory architecture. Convergence in telecommunications is propelled by ideas, ideologies, and policies progressively and cyclically, bringing further technological advancement, market, business, and policy changes. As a response to convergence, net neutrality seeks to regulate the relationship between Internet service providers and users to avoid discriminatory practices and ensure the openness of the Internet as a platform for innovation, economic development, and access to information for all. The objective of this work is to analyze the development of convergence in the telecommunications sector and the progress of net neutrality policies in South America, with five specific cases using a qualitative empirical approach. Within the findings, we identify different approaches for legislating net neutrality, controversies concerning the levels of commitment to the principles, ambiguity for effective enforcement of the rules, and commercial arrangements that in practice violate net neutrality.
Transfer learning en la clasificación binaria de imágenes térmicas

La clasificación de imágenes térmicas es un aspecto clave en el sector industrial, debido a que suele ser el punto de partida en la detección de fallos en equipos eléctricos. En algunos casos, esta tarea se automatiza mediante el uso de técnicas tradicionales de inteligencia artificial, mientras que en otros, es realizada de manera manual, lo cual puede traer consigo altas tasas de error humano. Este artículo presenta un análisis comparativo entre once arquitecturas de transfer learning (AlexNet, VGG16, VGG19, ResNet, DenseNet, MobileNet v2, GoogLeNet, ResNeXt, Wide ResNet, MNASNet y ShuffleNet) mediante el uso de fine-tuning, con la finalidad de realizar una clasificación binaria de imágenes térmicas en una red de distribución eléctrica. Para ello, se dispone de una base de datos con 815 imágenes, divididas mediante la técnica tipo hold-out 60-20-20 y validación cruzada con 5-folds, para finalmente analizar su rendimiento mediante el test de Friedman. Luego de los experimentos, se obtuvieron resultados satisfactorios con exactitudes superiores a 85 % en diez de las arquitecturas previamente entrenadas. Sin embargo, la arquitectura que no se entrenó previamente presentó una exactitud baja; concluyéndose que la aplicación de transfer learning mediante el uso de arquitecturas previamente entrenadas es un mecanismo adecuado en la clasificación de este tipo de imágenes, y representa una alternativa confiable frente a técnicas tradicionales de inteligencia artificial.

Peran Pemerintah dalam Pemenuhan Hak untuk Mendapatkan Pekerjaan bagi Penyandang Disabilitas
Authors: Sukmawati Nindiya
Published: November 2021

Pasal 1 Ayat (3) Undang-Undang Dasar 1945 berbunyi “Negara Indonesia adalah negara hukum”, yang memiliki tujuan persamaan dalam hukum atau di kenal dengan (eduality before the law), memiliki hak dan kewajiban serta perlakuan yang sama di hadapan hukum. Jaminan dan perlindungan hak dapat diperoleh seluruh masyarakat Indonesia tidak hanya berlaku untuk masyarakat normal, tetapi juga dapat diperoleh untuk masyarakat berkebutuhan khusus tentunya perlu ditingkatkan. Tujuan penelitian ini untuk mengetahui peran pemerintah dalam penangan ketenagekerjaan penyandang disabilitas serta hambatan yang dihadapinya. Perda Kota Yogyakarta Nomor 4 Tahun 2019 tentang perlindungan dan pemenuhan hak-hak penyandang disabilitas, merupakan salah satu bentuk peran pemerintah.  Pemerintah merealisasikan kegiatan-kegiatan yang mendukung penyandang disabilitas ikut dalam pemenuhan haknya yaitu 1% untuk dipekerjakan. Pemberian bekal keterampilan juga merupakan salah satu peran yang telah dijalankan. Peraturan sanksi yang kurang tegas bagi perusahaan yang tidak mempekerjakan penyandang disabilitas, ketidaksadaran mengenai kewajiban mempekerjakan penyandang disabilitas, masyarakat sekitar yang kurang peduli dengan penyandang disabilitas menjadi penghambat pelaksanaan program kerja pemerintah dalam penanganan ketenagekerjaaan penyandang disabilitas. Pada dasarnya pemerintah telah berperan besar dalam permasalahan ketenagakerjaan bagi penyandang disabilitas dengan segala hambatan yang di temui. Pelaksanaaan perda yang ada terkait ketenagakerjaan bagi penyandang disabilitas telah di maskimlakan pelaksannanya.
